[0029] By adopting the above technical solution, the slide groove 43 limits the limit block 45, so that the slider 44 can be limited and moved up and down inside the through groove 42.

[0030] Specifically, the top of the lifting plate 46 is connected to a fixing sleeve 466, the tops of both sides of the frame 2 are provided with gear 2 463, the bottoms of gear 2 463 are connected with screws 465, and fixing plates 461 are installed on both sides of the frame 2, an operating rod 464 is embedded in the inside of the fixing plate 461, and two gears 1 462 are sleeved on the surface of the operating rod 464, the operating rod 464 and the fixing plate 461 are connected in a limited rotation connection, and gear 1 462 and gear 2 463 are both connected in gear meshing.

[0031] By adopting the above technical solution, the rotating operating rod 464 can drive the two gears 463 to rotate synchronously under the meshing transmission between the gear 1 462 and the gear 2 463.

[0032] Specifically, the surfaces of the screw rods 465 are sleeved with limit rings 467 , and the screw rods 465 and the frame 2 are both connected to each other in a limited rotational manner.

[0038] When this embodiment is used, the two rotating rollers 1 can drive the hot melt adhesive film to move, and the hot melt adhesive film can pass between the upper dust removal roller 6 and the lower dust removal roller 7, and drive the upper dust removal roller 6 and the lower dust removal roller 7 to rotate, so that the dust removal paper can be contaminated with and remove the dust on the surface of the hot melt adhesive film, and the deformation force of the spring 1 41 acts on the slider 44 to press the slider 44 downward, so that the upper dust removal roller 6 and the lower dust removal roller 7 between the two sliders 44 can fit tightly, thereby making the dust removal effect of the dust removal paper on the surface of the upper dust removal roller 6 and the lower dust removal roller 7 better on the hot melt adhesive film, and the two gears 1 462 on the surface are driven to rotate by rotating the operating rod 464, and between the gear 1 462 and the gear 2 463 Under the meshing transmission, the two gears 463 can be driven to rotate, and the limiting ring 467 forms a limit on the screw 465 so that the screw 465 can rotate within the limit position inside the frame 2. Under the meshing connection between the screw 465 and the fixing sleeve 466, the slide groove 43 forms a limit on the limit blocks 45 on both sides of the lifting plate 46 so that the lifting plate 46 can be limited and moved downward. The downward movement of the lifting plate 46 will squeeze the spring 1 41, thereby increasing the force of the spring 1 41 on the slider 44, and the up and down movement of the lifting plate 46 can be controlled to control the pressure between the upper dust removal roller 6 and the lower dust removal roller 7, so that the device can adapt to hot melt adhesive films of different thicknesses for effective dust removal, and the adjustment is convenient and the dust removal effect is good;
