In this process, because the dust removal roller is located in the box, and the sticky tape on the surface of the dust removal roller is actually used, each rotation will make the dust absorption effect worse than the previous one, which leads to uneven dust removal effect and affects the quality of the product.

[0025] Please refer to Figure 1-5 As shown, it shows the specific structure of the preferred first embodiment of the utility model, which is a film dust removal mechanism, including a dust removal bin 20 and a conveying frame 10 arranged at the inlet and outlet ends of the dust removal bin 20, a rotatable roller 21 is arranged in the dust removal bin 20, and a dust removal assembly 22 is connected to the side of the roller 21, and the dust removal assembly 22 includes a liquid supply end a and a cleaning end b that conflict with the roller 21;

[0026] When the roller 21 rotates, the liquid supply end a of the dust removal component 22 coats the solution on the surface of the roller 21; when the roller 21 rotates to the cleaning end b, the solution on the roller 21 is absorbed into the flow channel c of the dust removal component 22. Compared with the existing film dust removal mechanism in which the roller 21 is a roller body containing static electricity and the roller 21 is attached to the sticky side of the tearable paper to clean the dust adsorbed on the roller 21, the film dust removal mechanism wets and cleans the surface of the roller 21 through the dust removal component 22, thereby reducing the dust removal cost and enhancing the dust removal effect.

[0027] Specifically, the film is placed on the conveying rack 10, moved by the conveying rack 10 to the inlet end of the dust removal bin 20, and discharged from the outlet end of the dust removal bin 20 through the squeezing and pulling of the roller 21, and then moved to the conveying rack 10 again. During this process, the dust originally remaining on the surface of the film is adsorbed on the roller 21, and the roller 21 is an electrostatic roller to enhance the dust absorption effect. Taking the rotation direction of the roller 21 as an example, the cleaning end a is located behind the liquid supply end b, and the dust on the roller 21 is first soaked by the cleaning end a, and then the liquid is removed and dust is removed by the liquid supply end b. After the liquid supply end b removes the dust and liquid on the surface of the roller 21, the part of the liquid containing dust is sucked into it due to the negative pressure at the flow channel c, thereby forming an effective dust removal on the surface of the roller 21 and keeping the surface of the roller 21 dry to reduce the impact on the film.

[0028] like Figure 1As shown, the roller 21 includes two opposite first and second rotating rods 211 and 212, and the contact surface between the first and second rotating rods 211 and 212 corresponds to the conveying surface of the conveying frame 10. To facilitate the film entering the dust removal bin 20 to be smoothly removed from the dust removal bin 20, the roller 21 includes two first rotating rods 211, wherein the first rotating rod 211 is located above the second rotating rod 212, and there is a gap between the first and second rotating rods 211 and 212 for the film to be inserted, and the lower part of the gap corresponds to the conveying surface of the conveying frame 10, so that the first and second rotating rods 211 and 212 can squeeze the film inserted into the gap, so as to better remove dust on the film.

[0029] like Figure 5 As shown, the dust removal assembly 22 includes a liquid storage rod 23 disposed in the dust removal bin 20, and one side of the liquid storage rod 23 is provided with liquid outlet holes 231 for solution circulation at equal intervals, and the liquid supply end a is located at the contact end between the liquid outlet holes 231 and the roller 21. The liquid outlet holes 231 are arranged horizontally on the liquid storage rod 23 and are closely attached to the surface of the roller 21. As the roller 21 rotates, the liquid in the liquid storage rod 23 is discharged from the liquid outlet holes 231 and wets the surface of the roller 21, so as to facilitate the extrusion strip 24 to remove the dust adsorbed on the surface of the roller 21.

[0030] like Figure 3 As shown, the dust removal assembly 22 also includes an extrusion bar 24 in contact with the surface of the roller 21, and the cleaning end b is located at the contact surface between the extrusion bar 24 and the roller 21, and the cleaning end b is attached to the surface of the roller 21. The contact surface between the extrusion bar 24 and the roller 21 is in the shape of a blade, but is not sharpened. As the roller 21 rotates, the liquid mixed with dust on it is squeezed and moved to the surface of the extrusion bar 24, and the surface of the roller 21 becomes dry and tidy, thereby ensuring that the roller 21 can effectively remove dust on the film.

[0031] like Figure 3-4 As shown, illustratively, the dust removal component 22 also includes a guide bar 25 connected to the top of the extrusion bar 24, the guide bar 25 is hollow, and the flow channel c is located in the inner cavity of the guide bar 25, and the flow channel c corresponds to the side of the guide bar 25 close to the rotation direction of the roller 21. The dust removal component 22 also includes a reinforcing rib 26, and the flow channel c on the guide bar 25 is connected to the inner cavity of the reinforcing rib 26, and the inner cavity of the reinforcing rib 26 is connected to an external suction device. In order to recover the liquid moved to the extrusion bar 24, the suction device is started to allow the liquid on the extrusion bar 24 to enter the inner cavity of the reinforcing rib 26 from the flow channel c on the guide bar 25, so as to prevent the liquid on the extrusion bar 24 from flowing back, or overflowing from both sides of the extrusion bar 24 and affecting other structures.

[0032] like Figure 2As shown, the surface of the liquid storage rod 23 contains a rubber coating, and the liquid outlet hole 231 passes through the rubber coating. The rubber coating on the surface of the liquid storage rod 23 increases the degree of fit between the liquid storage rod 23 and the roller 21, and prevents the liquid in the liquid storage rod 23 from overflowing from the liquid outlet hole 231 when the roller 21 is not rotating.

[0033] The liquid storage rod 23 is a hollow rod, and an infusion piece 232 communicating with the inner cavity of the liquid storage rod 23 is provided on the liquid storage rod 23 .

[0034] To sum up, the design focus of the utility model is that when the roller rotates and pulls the plate to move, because the roller is an electrostatic rod, the dust on the plate will be adsorbed onto the roller 21. When the dust-containing side of the roller moves to the liquid outlet 231, the liquid in the liquid storage rod 23 flows out and soaks the surface of the roller 21. When the wetted side of the roller 21 moves to the extrusion bar 24, the liquid on the roller 21 is squeezed and moved to the extrusion bar 24, and is sucked into the reinforcing rib 26 through the negative pressure at the port of the guide bar 25, thereby ensuring the dust removal effect of the roller 21 on the plate.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
