[0042] It should be noted that the limiting tube 261 and the piston rod 264 are in the structure of a cylinder, and when the piston rod 264 moves, it can pass through the limiting inclined rod 266, thereby limiting the extension distance of the limiting tube 261 and the limiting inclined rod 266. The surface of the limiting tube 261 is provided with the first air hole 262 and the second air hole 263, the hole diameter of the first air hole 262 is larger than that of the second air hole 263, so that when the piston rod 264 slides to the inside of the limiting tube 261, the speed can be slowed down to prevent the problem of impact caused by the rapid resetting of the cleaning piece 23, and the stability of the device operation is improved. When the rod on the first limiting block 265 is pressed by the first telescopic rod 15, the second limiting plate 268 can be rotated, so that the limiting inclined rod 266 can be raised, so that the piston rod 264 can be reset to slide in the inside of the limiting tube 261.

If the collecting bin 241 needs to be cleaned, the door plate 242 can be opened through the handle 244, and the inside of the collecting bin 241 can be cleaned.

[0045] As shown in the figure, Figures 2 to 8 A torsion spring is arranged at the connecting position between the first mounting plate 27 and the first limiting plate 22.

[0046] It should be noted that the torsion spring is arranged at the connecting position between the first mounting plate 27 and the first limiting plate 22, so that the plurality of extrusion cleaning pieces 23 on the two first limiting plates 22 have a force of approaching each other, so that when the extrusion cleaning piece 23 contacts the surface of the first polarizing plate 13, the surface of the first polarizing plate 13 can be rolled and extruded and flattened.

[0047] As shown in the figure, Figure 8 The bottom arc of the scraper 243 is the same as the outer arc of the extrusion cleaning piece 23.

[0048] It should be noted that the bottom arc of the scraper 243 is the same as the outer arc of the extrusion cleaning piece 23, so that the scraper 243 can contact the surface of the rubber extrusion cleaning ring 231, thereby improving the cleaning effect.
