[0036] By manual rotation screw rod 5, it is moved upwards with sliding plate 11 and two upper rollers 14, so that two upper rollers 14 are pulled apart from lower roll 8 by moving upwards, so that the difficulty of connecting decorative cloth between lower roll 8 and upper roller 14 is reduced by increasing distance, and the convenience of connecting decorative cloth is improved.

[0037] In example two, on the basis of example one, sliding slot 10 is slidably installed with sliding plate 11;Sliding plate 11 is connected with screw rod 5 by thread;Spring A12 is embedded between the top of sliding plate 11 and the top end of sliding slot 10;Upper shaft 13 is rotatably installed on sliding plate 11;Upper roll 14 is fixedly installed on the circumferential outer wall of upper shaft 13;Upper gear 15 is also fixedly installed in left-right symmetry on the circumferential outer wall of upper shaft 13;Upper gear 15 is connected with lower gear 9 by meshing;Pressure plate 17 is embedded on the outer wall of sliding plate 11 by spring B16;Force receiving part 18 is fixedly installed on the outside of pressure plate 17;The outer end of force receiving part 18 is inclined structure;Limiting column 19 is fixedly installed on the inside of pressure plate 17;Limiting column 19 is located at the left and right ends of upper shaft 13.

[0038] When upper roller 14 moves upwards, the slope of groove on fixed part 6 will push the slope of force receiving part 18, so that force receiving part 18 is forced to move inward with pressure plate 17 and limiting column 19, so that limiting column 19 is forced to rub with the two ends of upper shaft 13, so that the rotation flexibility of upper shaft 13 is reduced, so that the tooth angle of upper gear 15 can be maintained to a certain extent by the friction contact between limiting column 19 and upper shaft 13 after upper roller 14 and lower roll 8 are separated, and the secondary precise meshing of upper gear 15 and lower gear 9 is facilitated.

[0039] In example three, on the basis of example two, a groove is formed in the inner top of the fixing member 6, and the top of the groove is in an inclined structure; the inclined surface of the groove on the fixing member 6 is in contact with the inclined surface of the force receiving member 18; the front side of the fixing member 6 is fixedly installed with a lower splash-proof shell 20; the lower splash-proof shell 20 covers the lower coating pipe 4 in each group of coating pipes 4; the front side of the sliding plate 11 is fixedly installed with an upper splash-proof shell 21; the upper splash-proof shell 21 covers the upper coating pipe 4 in each group of coating pipes 4.

After the decorative cloth is spliced, the screw rod 5 is reversed to control the sliding plate 11 and the upper roller 14 to descend, so that the upper roller 14 is clamped with the lower roller 8 to facilitate the subsequent conveying of the decorative cloth. Then, the motor 2 directly or indirectly rotates the two lower shafts 7, so that the upper roller 14 and the lower roller 8 rotate relatively under the cooperation of the lower gear 9 and the upper gear 15, thereby realizing the conveying of the decorative cloth. During the conveying process, the coating material is released through the coating pipe 4 to coat the decorative cloth.
