Locking nut 11, hinge plate 12 is hinged to the other end of the first U-shaped plate 6, and hinge plate 12 is locked to the first U-shaped plate 6 by locking bolt 13. One end of the first rotating shaft 7 is placed on the first U-shaped plate 6 through the mounting block 10 and the through hole, so that the other end of the first rotating shaft 7 is located in the through hole. Rotating hinge plate 12, the locking bolt 13 limits the hinge plate 12, thereby realizing the installation of the first rotating shaft 7 and the first cleaning roller 8. Two fixing plates 14 are symmetrically fixed on the worktable 1. The second rotating... Two locking blocks 16 are symmetrically fixedly installed on the shaft 15. The two locking blocks 16 are respectively engaged with two fixed plates 14. A second cleaning roller 17 is rotatably mounted on the second rotating shaft 15. Limiting plates 18 are rotatably installed on both fixed plates 14, and the two limiting plates 18 respectively engage with the two locking blocks 16. By engaging the two locking blocks 16 onto the two fixed plates 14 and rotating the two limiting plates 18, the two limiting plates 18 limit the two locking blocks 16, thus realizing the installation of the second cleaning roller 17. The two first electric cylinders are then activated. 5. The first U-shaped plate 6 and the first rotating shaft 7 are moved by the two first electric cylinders 5, so that the first cleaning roller 8 and the second cleaning roller 17 are brought closer to each other. The substrate is placed on the take-up roller 4, and one end of the substrate passes through the first cleaning roller 8 and the second cleaning roller 17. The dust attached to the substrate is cleaned by the cooperation of the limiting plate 18 and the second cleaning roller 17, so that the composite effect is better. The mounting frame 3 is rotatably mounted with a conveyor roller 20, which conveys the substrate and performs the composite through the laminating machine body 2.

The two limiting plates 18 are rotated to limit the two clamping blocks 16, thus achieving the installation of the second cleaning roller 17. The two second bolts 19 limit the two limiting plates 18, making the second cleaning roller 17 more stable. The two first electric cylinders 5 are started, and the two... The first electric cylinder 5 drives the first U-shaped plate 6 and the first rotating shaft 7 to move, bringing the first cleaning roller 8 and the second cleaning roller 17 closer together. The substrate is placed on the take-up roller 4, with one end of the substrate passing through the first cleaning roller 8 and the second cleaning roller 17. The dust adhering to the substrate is cleaned by the cooperation of the limiting plate 18 and the second cleaning roller 17, thereby improving the lamination effect. The two second electric cylinders 21 are activated, which drive the second U-shaped plate 22 and the auxiliary roller 23 to move, thereby facilitating the adjustment of the material tension.
