a first through hole (512) is formed in the baffle (53), and a plurality of cooling rods (513) which are distributed at equal intervals are fixedly connected in the first through hole (512);

two ends of the anti-fouling plate (56) positioned in the stain collecting hole (514) are respectively provided with a second through hole (515), and the insides of the two second through holes (515) are respectively and fixedly connected with an anti-leakage net (516);

when the device is used, firstly, the art paper body (2) on the unreeling roller (11) sequentially penetrates into the clamping plate (31), the laminating box (41) and the drying box (51), and finally the art paper body is wound on the reeling roller (12), the reeling roller (12) is rotated, the uniform rotation of the reeling roller (12) is guaranteed, meanwhile, a liquid spraying pipe (35) switch of the liquid storage tank (34) is opened, liquid spraying is started to be carried out on the surface of the art paper body (2), then the motor (410) is started, the output shaft rotates to drive the rotating arm (49) to rotate, because the laminating plate (43) is limited by the guide rod (42), the pushing block (48) can only move up and down in the sliding groove (47), and when the rotating arm (49) does circular motion, the pushing block (48) is firstly driven to reciprocate up and down in the sliding groove (47), the laminating plate (43) is further driven to reciprocate left and right on the guide rod (, thereby, the coating wheel (411) is used for coating the pasty polyvinyl chloride resin liquid on the surface of the coated paper body (2), the pasty polyvinyl chloride resin liquid is ensured to be flattened, a film is formed to be attached to the surface of the coated paper body (2) under the reciprocating coating and extrusion, finally, the U-shaped heating rod (54) and the fan device (55) are opened, the coated paper body (2) with the film can accelerate the surface drying after passing through the drying box (51), the filter screen (510) and the leakage-proof screen (516) can block the stain flowing in from the air pipe (511) and avoid falling onto the coated paper body (2) to influence the whole quality, meanwhile, a plurality of cooling rods (513) are arranged to avoid the coated paper body (2) from being damaged due to excessive heat, the dried coated paper body (2) can be finally wound on the winding roller (12), and the process only carries out the coating process on one side of the coated paper body (2), after the surface is completely coated, the coated paper body (2) on the winding roller (12) and the unwinding roller (11) need to be exchanged once to coat the other surface, and the process is the same and the circular operation is carried out.
