A kind of positive and negative coating process of batch (-type) and coating machine thereof
[technical field]
The present invention relates to a kind of coating or technique and coating machine, this technique and coating machine can be answered
For coating or print field, particularly to the positive and negative coating process of batch (-type) and coating machine.
[background technology]
Due to actual demand, generally will in base material (such as laser film) front, reverse side coating,
And dispensing area on each face needs interval necessarily to have.Existing positive and negative coating process
More complicated, cause coating machine result complicated, work efficiency is the highest, and the precision of interval coating is not
Height, so that yield rate is low.
[summary of the invention]
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of technique is simple, painting
The positive and negative coating process of batch (-type) that cloth precision is high, its another purpose is a kind of structure list of offer,

[detailed description of the invention]
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings:
As shown in Figures 1 to 4, a kind of positive and negative coating process of batch (-type), it is characterised in that include
Following step:
A: feeding, is housed in base material to be coated on unwinding unit 1.
B: pan feeding draws, and is led by the base material on unwinding unit 1 by pan feeding traction apparatus 2
It is pulled out.
The interval coating of C: front, base material is linked into from the discharge end of pan feeding traction apparatus 2 and is just coated with list
Front coating roll 31 and first in unit 3 guides between dandy roll 32, at front coating roll
31 are coating coating fluid, then control front coating roll 31 and lead with first be just coated with on unit 3
To dandy roll 32 reciprocal near and be coated on base material away from by coating fluid, complete the one of base material
Face interval coating.It concretely comprises the following steps, and front coating roll 31 is provided with painting liquid bath 11, is just coated with
Being equipped with scraper 12 on unit 3, front coating roll 31 is by being just coated with the front on unit 3
After coating containment groove 35 makes painting liquid bath 11 load onto coating fluid, by scraper 12 by positive coating materials
The unnecessary coating fluid of roller 31 circumferential surface strikes off, and completes front coating roll 31 and coats coating fluid, this
Sample only has coating fluid in being coated with liquid bath 11, and first guides the fixing rotation of dandy roll 32 and to base material
Guiding, front coating roll 31 guides dandy roll 32 to first and moves, and will be coated with in liquid bath 11
Coatings is in base material one side.
D: dry for the first time, is linked into the first drying by the base material completing front interval coating
Device 4 is dried.
The interval coating of E: reverse side, the base material after drying for the first time is linked into anti-painting on unit 5
Reverse side coating roll 51 and second guide between dandy roll 52, at the anti-reverse side being coated with on unit 5
Coat coating fluid on coating roll 51, then control reverse side coating roll 51 and be coated with on unit 5 with anti-
Second guide dandy roll 52 reciprocal near and be coated on base material away from by coating fluid, complete base
The another side interval coating of material.It concretely comprises the following steps, front coating roll 31 and reverse side coating roll
Being equipped with painting liquid bath 11 on 51, the anti-unit 5 that is coated with is provided with scraper 12, reverse side coating roll 51
Painting liquid bath 11 is made to load onto coating fluid by the anti-reverse side coating containment groove 55 being coated with on unit 5
After, by scraper 12 by unnecessary for the circumferential surface of front coating roll 31 and reverse side coating roll 51
Coating fluid strikes off, and the most only has coating fluid at painting liquid bath 11, and second guides dandy roll 52 admittedly
Base material is also guided by fixed rotation, and reverse side coating roll 51 guides dandy roll 52 to second and moves, will
It is coated with the coatings in liquid bath 11 on base material another side.
F: second time is dried, is linked into second by the base material completing positive and negative interval coating
Drying unit 6 is dried;
G: discharging is drawn, and the base material after second time being dried is linked into discharging traction unit 7 and draws
Dynamic traction;
