Description
Technical field
The present invention relates to a kind of manufacture fields of UV photocuring films, more particularly to a kind of UV photocuring films multipoint mode injecting glue
Coating waste water technique.
Background technology
UV photocuring films generally comprise base film and UV glue-lines, and base film is common for PET film, and UV glue-lines are that photocuring applies
Layer.When film is processed, it usually needs UV glue is inverted in ink tank in advance, the usual open design of the ink tank, film
When, mesh roller is dipped in dye ink in ink tank, and then the convex-concave surface of mesh roller is stored with UV glue；PET film is by being stored with UV glue
The mesh roller of water carries out printing coating, and then UV glue is coated on PET film, and UV glue cures finally after photosensitive device is handled
UV glue-lines are formed, UV photocuring films are collectively formed in PET film and UV glue-lines.Traditional film processing exists as following drawbacks：1, due to
Ink tank open design, UV glue is easy to be mixed with the dirts such as dust in slot, causes the texture of UV photocuring films unclear；2, by
It is in light-exposed state in the ink in ink tank open design, slot, UV glue is light-exposed to lead to its premature cure, therefore light meeting
Coating operation is interfered；3, due in slot glue be mixed with more dust or the easy premature cure of glue, it is therefore desirable to periodically
Ink wash is carried out to ink tank or changes glue, ink can be caused to waste in this way.Just may be used in addition, needing to hold more ink in ink tank
Dye ink is carried out convenient for mesh roller, when applying membrane operations stopping, the UV glue of surplus is finally typically due to pollution in slot and solidification is asked
It inscribes and can not be continuing with, further result in waste.
Invention content
In view of this, the purpose of the present invention is to provide it is a kind of it is easy to operate, save raw material, avoid outside contamination, UV
Photocuring film multipoint mode injecting glue coating waste water technique.
In order to achieve the above objectives, the technical scheme is that：
A kind of UV photocuring films multipoint mode injecting glue coating waste water technique, includes the following steps：
(1) material volume is installed on discharging roll, one end of material volume sequentially passes through between guide roller set, coating counter-pressure cylinder and texture
It between roller, between traction counter-pressure cylinder and carry-over pinch rolls, is finally connected on wrap-up, the membrane layer portion of material volume is overlaid on the coating back of the body
On pressure roller；
(2) the first cylinder is driven so that realize and be in rolling contact between coating counter-pressure cylinder and texture roller, form V-groove；It drives
Dynamic second cylinder so that realizes and is in rolling contact between traction counter-pressure cylinder and carry-over pinch rolls, between traction counter-pressure cylinder and texture roller there are
Gap；
(3) height and position to its outlet end for reducing injecting glue syringe needle is located in V-groove, and when injecting glue, starting switch valve makes
UV glue is obtained to wander in the bottom of vee-cut；
After the outlet end of injecting glue syringe needle is immersed under the liquid level of the UV glue in V-groove, starts workbench and enter painting
Cloth working condition, when coating, injecting glue syringe needle persistently keeps injecting glue state, while being coated with roller group and squeezing the UV glue in V-groove
Pressure is spread out coated on PET film, and UV function of glue coating is formed；
(4) when photocuring, UV function of glue coating passes through solidification and the second UV lamp of the first UV lamp successively during traveling
After solidification, UV light solidifying coatings are formed, UV photocuring films are collectively formed with PET film in UV light solidifying coatings；
(5) wrap-up winds UV photocuring films.
Further, when step (3) is coated with, while injecting glue by PLC control system control injecting glue syringe needle carry out it is reciprocal
It swings.
Further, when workbench enters coating work state in step (3), texture roller is occurred by the driving of servo motor
Rotation further drives coating counter-pressure cylinder reversely to roll by the extruding force between texture roller and coating counter-pressure cylinder；
The height of the outlet end of injecting glue syringe needle is kept to be located relatively at the position of UV glue liquid levels in 1/2~3/4V type grooves
It sets.
Further, when coating, the line pressure of texture roller is 10-280kg/cm2；Film roll curve speed is 8m/min.
Further, the exposure intensity of the first UV lamp is 400W/cm2, the exposure intensity of the second UV lamp is 2000W/cm2。
Further, in step (4), before photocuring, first start cooling system and distinguish texture roller and carry-over pinch rolls
It is set in constant temperature, thermostat temperature is less than or equal to 20 DEG C.
Further, the thickness difference of UV light solidifying coatings obtained is less than or equal to 0.1um in step (4).
A kind of UV photocuring films multipoint mode injecting glue coating waste water technique of the present invention, compared with traditional technology, it is easy to operate,
When coating, injecting glue coating is carried out using the cooperation of V-groove and injecting glue syringe needle, glue can be saved, will not cause to waste, solve simultaneously
Determined UV glue premature cures the problem of, and the UV light solidifying coatings uniformity after being coated with is good, and product quality is high.

It opens coated on PET film, forms UV function of glue coating；
(4) when photocuring, UV function of glue coating passes through the solidification of the solidification and the second UV lamp of the first UV lamp successively during traveling
Afterwards, UV light solidifying coatings are formed, UV photocuring films are collectively formed with PET film in UV light solidifying coatings；
(5) wrap-up winds UV photocuring films.
2. a kind of UV photocuring films multipoint mode injecting glue coating waste water technique as described in claim 1, it is characterised in that：Step
(3) pass through PLC control system when being coated with, while injecting glue and control injecting glue syringe needle and carry out reciprocally swinging.
3. a kind of UV photocuring films multipoint mode injecting glue coating waste water technique as described in claim 1, it is characterised in that：Step
(3) when workbench enters coating work state in, texture roller is rotated by the driving of servo motor, further, passes through line
It manages roller and the extruding force being coated between counter-pressure cylinder and coating counter-pressure cylinder is driven reversely to roll；
The height of the outlet end of injecting glue syringe needle is kept to be located relatively at the position of UV glue liquid levels in 1/2~3/4V type grooves.
4. a kind of UV photocuring films multipoint mode injecting glue coating waste water technique as described in claim 1, it is characterised in that：Coating
When, the line pressure of texture roller is 10-280kg/cm2, film roll curve speed is 8m/min.
5. a kind of UV photocuring films multipoint mode injecting glue coating waste water technique as described in claim 1, it is characterised in that：First UV
The exposure intensity of lamp is 400W/cm2, the exposure intensity of the second UV lamp is 2000W/cm2。
6. a kind of UV photocuring films multipoint mode injecting glue coating waste water technique as described in claim 1, it is characterised in that：In step
(4) in, before photocuring, first start cooling system texture roller and carry-over pinch rolls are set in constant temperature respectively, thermostat temperature be less than
Or it is equal to 20 DEG C.
7. a kind of UV photocuring films multipoint mode injecting glue coating waste water technique as described in claim 1, it is characterised in that：In step
(4) the thickness difference of UV light solidifying coatings obtained is less than or equal to 0.1um in.
