roller) of the ink transmission device can be automatically cleaned by manipulating
the button on the touch screen.
二、Notes
2.1、Use of UV offset printing inks
which are suitable for UV ink (UV curing ink) printing. When using printing ink,
because UV offset ink chemical properties are different from traditional offset ink,
the use of traditional offset ink will affect the transmission performance of water
and ink transfer.
(1)The quality of rollers is very important to ensure the printing quality. Only
good quality rollers can provide the best transmission effect.
(2)Accurate adjustment of the best pressure between the rollers can optimize the
performance of water and ink transmission and extend the service life of the rollers.
(3)High quality rollers and the best pressure can ensure that the offset press has
a high quality of printing
2.2、Basic requirements for printing
(1)Adjust the output parameters of UV dryer to printing requirements.
(2)Use PS plate suitable for UV offset printing. If you use an ordinary PS plate,
you must perform a toasting treatment to improve its corrosion resistance.
(3)Use UV self-adhesive blanket.
(4)Use UV ink special auxiliaries, additives and cleaning agents.
with other types of UV ink.
(6)Do not use UV ink that beyond warranty period.
(7)Do not overuse additives in UV ink. If overuse, it is easy to cause ink film
drying and other problem.
Page 28
28
(8)Compared with the traditional ordinary offset ink, UV ink balance tolerance is
narrower, it is easy to cause ink emulsification, dirty plate, etc.. Especially at
the beginning of printing, the supply of UV ink in the ink ductor is not very smooth,
and then ink is gradually increased. Therefore, it is important to adjust the amount
of ink and water supply to reach the balance.
2.3、Storage, Maintenance and Transportation of rollers
(1)After printing, make sure to clean the ink on the surface of the roller, and
the ink can not be left on the roller.
(2)If there is a hard film on the roller surface, it musts remove as early as
possible. If there is crack on roller glue surface, it musts grind in time.
(3)Temporary storage of rollers must be placed on the shelf.
(4)When the roller is kept for a long time, it must be supported at both ends of
the shaft. There should be space between the rollers. It is forbidden to squeeze
each other to prevent the adhesive from being deformed or sticking. The surface of
the long-term preservation rollers may produce cracks, which must be ground before
use.
(5)Rollers should be kept in a cool, dry, ventilated place in the room. Rollers
are wrapped in paper or plastic film to prevent aging of the rubber surface. Storage
should not be with acids, bases, oils, and sharp hard materials, so as to avoid
corrosion or bump. The metal parts exposed at both ends of the roller should be
protected against rust.
(6)Rollers should be loaded into wooden cases when transportation. In order to
and the boxes.
2.4、UV ink storage
UV ink should be kept in a cool and dry room, avoiding room temperature above 30 °C
or direct sunlight.
2.5、Clean rollers During the printing process, impurities such as paper hair, paper powder, ink will adhere to the surface of the roller, or they will be deposited in the micropores on the surface of the roller or in liquid, which will easily cause the surface of the roller to harden (glaze). Thus it makes influence on the ink transfer performance of the roller. Therefore, in addition to ink replacement, the ink transfer and dampening device should also be thoroughly cleaned once a week at least. When printing coated paper or plastic film, the time interval for cleaning rollers need
to be shortened to 3-4 days. When the ink transmission device is not used for a long
time, the ink bucket and the ink roller must also be cleaned. After cleaning, wipe with a soft, clean, fiberless fluff with a good absorbent cloth.
Specially Recommended Method for Cleaning UV Ink Roller
(1)Close the ink knife in the ink washers, use UV ink special cleaning agent to
pre-clean and remove ink till the ink roller surface is clean.
Page 29
29
for deep cleaning, then start the machine to make the ink roller running for 3 to 5
minutes, the deep cleaning cream can clean the stubborn ink wax.
(3)Then spray the calcium removal agent on the ink roller, start the machine to
make the ink roller running for 3 to 5 minutes, so that it is fully mixed with the
cleaning cream on the ink roller.
(4)About 5 minutes shut down, so that the roller calcium removal agent and
cleaning cream stay on the roller chemical effect.
(5)Close the ink knife once again, start the machine to make the ink roller
running 3 to 5 minutes, use the UV wash water to clean the roller again, and finally
use water to thoroughly wash the roller clean.
After deep cleaning, the surface of the roller is clean and the elastic of the
rubber layer is restored, and the ink transfer performance is improved.
If it is not possible to clean the surface of the roller with stubborn wax, remove
the roller from the machine for manual cleaning. If it is not possible to clean the
surface, the rollers must be replaced

一、Die-cutting cylinder
The die-cutting cylinder assembly consists of magnetic die-cutting cylinder, axial
adjustment device, die-cutting gear and bearing seat, etc..
1.1 Magnetic die-cutting cylinder is the installation position of the die-cutting tool. There is a clear side busbar on the outer circle of the cylinder. It is the benchmark for tool installation. The edge of the tool plate at the time of installation must be the same as the side busbar. This will facilitate the overlap of the die-cutting tool and the die-cutting pattern, cutting out the perfect icon.
1.2 The role of the axial adjustment device is to adjust the position of the die-
cutting tool and the die-cutting pattern in the axial direction, to lift the
limited-position sign, and to rotate the drawing sleeve, which will cause the
magnetic die-cutting cylinder to shift in the axial direction, To reach our desired
position, put down the limit sign to lock the drawing sleeve position to avoid axial
displacement of the tool during work.
1.3 Every time a magnetic roller is used, it is important to check whether the die-
1.4 Don't try to check the cutting tool with your hand for sharpness, which will
cause you harm
二、Cutting board cylinder
2.1、The cutting board cylinder is used as a bearing cylinder for die-cutting unit.
The dimensions of the outer circle and the roller pillow are the same. The
Page 59
59
roller pillow is tangent to the die-cutting magnetic roller pillow to form a
gap of 0.48 mm for the installation of the die-cutting tool.
2.2、The cutting board cylinder is fixed in the die-cutting unit. It depends on the
bearing seat and driving roller at both ends to limit it. During use, the
bearings in the bearing seat at both ends must be lubricated regularly. The
lubrication period is once every quarter. Lithium-based lubrication is
recommended.
Page 60
60
三、driving roller
3.1、The driving roller is the source of the die-cutting cylinder and the cutting
board cylinder positioning and power. It forms a connection with the servo
motor through the gearbox, and controls the gear transmission moment and
direction of the side end to the die-cutting cylinder and the cutting board
cylinder gear.
3.2、In the die cutting unit, the driving roller, the cutting board cylinder, and
the die cutting cylinder are all used to control the clearence through the
roller pillow. Therefore, the lubrication and cleaning of the roller pillow are
very important. On the die-cutting frame, a pair of felt is pressed on the
roller pillow of the driving roller under the action of a Reed. It assumes the
role of cleaning the pillow and oil storage lubrication.
3.3、The lubricating oil model used in the gearbox is Mobile gear 629, ISO VG 150.
There is a cursor on the gearbox that can check the capacity of the oil at any
time. There is an internal hexagonal flat end tightening screw on the upper
part of the gearbox. The rotation can inject oil into the gearbox. The
injection period is twice per year.
Page 61
61
四、Die-cutting frame assembly
4.1、The die-cutting frame assembly is the framework for the installation of the
entire die-cutting unit and provides positioning and constraints for all
components installed on the frame.
4.2、The axial displacement of the long and short guide bar can be realized by
rotating the exposed handle, so that the pressure mechanism component can be
loaded and locked.
4.3、The guide roller in the middle position can be quickly dismantled. After
removing the sheet metal cover shells on both sides, the guide roller is
rounded with a hand-held guide roll. The other hand forces the quick handle to
press the inside of the handle to remove it from the limit slot. And rotate to
the exit channel, You can remove the quick handle, and after dismantling, you
can remove the guide roller.
Page 62
62
五、Pressure mechanism component
5.1、The main role of the pressure mechanism is to complete the installation and
disassembly of the die-cutting cylinder and the cutting board cylinder, and to
provide a stable cutting pressure to the die-cutting cylinder during work. The
installation and disassembly are achieved by connecting two screws ① with the
cylinder assembly. The steady cutting pressure is achieved by the pressure of
the top screw④.
5.2、When working, the screw cover ② on the two ends of the screw must be rotated
to ensure that the screw is in a tensionless state and avoid interference with
the pressure of the top screw ④. When die-cutting is not required, the top
slider③can be opened, the pressurized screw ④ can be lifted to the bottom and
locked after disengagement, the two ends of the sleeve can be rotated, and the
die-cutting cylinder and gear can be lifted away from the cutting board
cylinder and gear. This reduces the load of the die cutting unit motor and the
inertia of the equipment.
Page 63
63
六、Safety cover assembly
6.1、The safety cover is connected to the die-cutting frame through a sliding track.
There is a safety switch at the end of the safety cover. When the cover is open,
the switch is disconnected. At this time, the device can not start working.

The most commonly method for the removal and disposal of waste belts is to remove
them from the material. The stripping roller is used to peel the waste belt from the
material after die-cutting. The adjustable bracket can be turned, and it can be
fitted with two sizes of stripping rollers. In order to ensure the most suitable
disposal related to anti-stick rollers, it is necessary to change the position of
the adjustment bracket and the size of the stripping roller, and adjust the
stripping roller to a suitable position. The clamping sensitive label is composed of
some surface materials and adhesives. In order to increase friction and avoid
adhesive affecting waste collection, a layer of diamond sand anti-slip tape is stuck
on the anti-stick roller.

Oil Storage Plot
The concentrated lubrication of dilute oil mainly provides lubrication for the ink
driving gears of each unit. The standard configuration provides three lubrication
points for each unit. The entire system is automatic lubrication, and users can use
it according to the specific circumstances of use. Set the fuel supply time and
period at the setting interface of the pump. After the setting procedure is
Page 76
76
completed and loaded, the system will perform lubrication according to the new
setting.
The centralized lubrication system is a system that can be lubricated with little
maintenance, but it does not mean that it can not be maintained. First of all, it
must ensure that the oil storage capacity in the oil tank of the oil pump is within
a safe scale. Secondly, the injection pipeline also needs to be filled. It is
recommended that the above contents be visually inspected. It is a simple and
effective method.

used more often in the equipment, and is distributed as below:
All gearboxes are equipped with cursors, exhaust valves, and fuel holes. It is very
important for the service life of the equipment to know clearly how much oil is
stored in the gearbox by the cursor. The main function of the exhaust valve is to
adjust the internal pressure of the sealed gearbox when the machine is running at
high speed for a long time. The fuel hole is a hole equipped with a flat end
fastening screw of M16 size. It is located in the upper part of the gearbox. When
installation, we have coated the perimeter of the device, which can be opened and
the gearbox is filled with oil when there is not enough oil in the cursor.
Dilute oil lubrication is also applied to all gears with no lubrication device
exposed. Generally, oil guns are used to fuel them. The locations that need
lubrication are distributed in the following locations.
二、Dry oil lubrication
Dry oil lubrication refers to the use of grease for lubrication, the use of a special pressure gun to press the grease through the pressure into the press type oil cup, lubrication of the bearings, these lubrication points are characterized by the existence of pressure type oil cups, they are mainly distributed in:

XII Maintenance
Proper maintenance and repair is the key to extend the service life of the machine
and ensure the normal use of the machine. The multi-function web machine should be
maintained according to the requirements of the manual for each unit.
1、Before the test run, the machine's oil, gas, circuit and parts of the machinery
should be fully inspected, the rust-proof oil should be cleaned, and the fuel tank,
the oil cup and the oil injection points should be refueled.
2、Check the operation status of lubricating workstation and lubricating oil route
regularly and troubleshoot in time. The new machine uses one month to clean the fuel
tank and replace the lubricant, and then cleans it every quarter to replace the
lubricant at the same time. All oil cups should be refueled in time, and no oil
cutting phenomenon should occur. Each oil injection point must be refueled with an
oil gun not less than twice per shift. The grease lubrication site shall be
supplemented promptly within 3000 hours of the cumulative working time of the
machine, and the oil shall be replaced regularly during the grease failure period to
ensure adequate lubrication.
3、Check frequently whether the air path is open, whether the air compressor and the
various gas circuit elements are normal. Weekly regular inspection of all interfaces
in the gas path, no leakage allowed
4、There is a power supply requirement of 380V10 % and 50HZ2 % three-phase AC power.
If the voltage fluctuation of the power grid may cause the automatic control to fail,
measures should be taken.
5、After the machine is installed and put into operation for about 70-80 shifts, the
level of the machine should be re-adjusted once, and it is recommended that the
level of the machine be re-adjusted every year.

⑵、When adjusting the ink-fountain screw, prevent the phenomenon of the screw top
to the ink roller.
(3)Always keep the ink blade and roller clean. When the ink blade adjustment is
not flexible during use, remove and clean, including the reverse side of the ink
blade and the end of the adjustment screw.
(4)The residual ink on the machine should be cleaned immediately after the
printing is completed. Only when the ink roller is at rest, the ink fountain can be
cleaned.
[Note]: At any time, fingers should not be near the end of the ink blade; When
adjusting the pressure of the ink washer and ink vibrating roller, do not squeeze
the ink scraper too tight. After cleaning, remove the ink washer in time to avoid
hitting the string ink roller.
11、Alcohol dampening device:
⑴、It is appropriate that the pH of the circulation tank should be 4.8 to 5.2. Set
the thermostat, the temperature is generally controlled at 9 ~ 11 °C (depending on
room temperature, the minimum temperature can be controlled at 5 ~ 7 °C). Adjust
the "alcohol automatic compensation regulator" ruler to 8% to 10%.
⑵、Before each shift is turned on for the first time, the proportion of alcohol in
the circulation tank and the PH value of the solution must be checked. If it is
found that it does not meet the requirements, it must be properly added with
propanol or bucket fluid. Keep the solution clean, if oil flowers are found, it
should be cleaned in time.
⑶、When not working for more than two days, the metering roller should be removed
in advance to avoid long-term pressure on the water fountain roller. During a long
vacation, the metering roller, intermediate roller and form dampening roller should
be removed to avoid pressing the rubber roller.
⑷、Each shift should be cleaned with an appropriate cleaning agent, especially on
the surface of the plate roller. Rollers (including ink rolls and water rolls)
should be removed every 20 days for thorough cleaning.
⑸、When washing ink, the metering roller and the water fountain roller must be
cleaned by hand
⑹、Check the pressure bar at least once every two months. Please refer to the ink
guide for indentation size.
⑺、Observe the backwater area of the fountain regularly, and do not allow water to
overflow the fountain. When the alcohol moisture in the water fountain does not
circulate, it is strictly forbidden to turn on.

⑻、For details of other relevant maintenance and repair matters of alcohol
dampening device, please refer to its equipment instructions.
⑼、Due to the different mineral content of water sources in various regions of the
country, which affects the configuration of the liquid, it is recommended to use
pure water.
12、Printing rollers
⑴、When the pressure between the rollers of the rough adjustment rubber is not
allowed to use steel plug sheets, it should use a thick polyester sheet of about 0.1
mm to avoid damaging the water rubber rollers.
⑵、Be sure to adjust the contact pressure of the roller before turning on. The
pressure at both ends of the roller must be the same. Otherwise, the pressure at one
end of the roller will cause wear and tear due to excessive pressure.
⑶、Be sure to immediately release the roller from the printing plate during
downtime and remove the load pressure. In long-term printing, due to the continuous
and high-speed rotation of the rubber roller, it is affected by the temperature,
pressure and tension, it will often reduce its elasticity, poor ink transfer, and
even produce ink bars, so it should regularly allow the rubber roller to recover
fatigue.
⑷、Do not use gasoline, diesel, oil refining and other solvents to clean the roller,
strictly prohibit the use of benzene or aromatic cleaning agents, otherwise it is
easy to cause the roller to soften prematurely, reducing the performance of the
roller. Wash with sufficient time and water at the end.
⑸、During the period of machine maintenance or long repair, the roller must be
completely removed and cleaned. Sand paper is not allowed to scrub and polish, this
will make the surface rough, so that it is difficult to wash ink and change ink.
⑹、When replacing the new roller, the gap between the rollers should be retreated
to the maximum possible, because the diameter of the new roller is larger than the
diameter of the old roller.
⑺、Store rollers should be lightly put, so as not to scratch, and to shelve the
level of rollers. Do not squeeze pile and cause rollers deformation; At the same
time, light avoidance measures can be used. It is not allow to placed under strong
light and ultraviolet light, so as not to cause the surface of the roller aging,
decolorization, cracking. It is not suitable to store outdoors in winter.
⑻、Other related maintenance and maintenance matters of printing rollers, ink
manual.

⑴、The water tank must be installed in a well-ventilated area with ambient
temperature of 6-28 degrees. There must be no obstacles within 1 meter around and it
must be away from the heat source to facilitate heat dissipation.
⑵、Filter sponges are often cleaned with grease remover and warm water. If they can
not work, they should be replaced in time.
⑶、The condenser shall remove dust and loot by compressed air or other means on a
weekly basis to ensure optimum cooling and cooling effect.
⑷、The return water and alcohol automatic compensation system must be cleaned once
a week to ensure that it works properly.
⑸、When alcohol is used up, the tank is prone to foam. Please turn off the alcohol
control switch immediately, then add alcohol to the alcohol bucket, and turn on the
control switch after the alcohol is added.
⑹、For other instructions on the use and maintenance of circulating refrigeration
tanks, see related instructions.
[Note]: Alcohol and ink are flammable substances. Please do a good job in fire
prevention measures. Fireworks are strictly prohibited.
15、Vacuum pressure composite pump
⑴、The air pump should be placed in a clean and ventilated place. There should be
no obstacles at the cooling air entrance and exit of the pump so as not to affect
the cooling effect.
⑵、The direction of the air pump rotation shall be consistent with the steering
sign and no reversal shall be permitted. After each connection, the motor should be
