Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows: referring to fig. 1, a dust adsorbing device for a carrier film includes a plurality of sets of dust suction units disposed in a conveying direction of a carrier film 2 between a wind-up roller 1 and a coating roller (not shown in the figure); each dust collection component comprises dust adhering rollers 3 which are oppositely arranged on two sides of the carrier film 2, a gap is arranged between each dust adhering roller 3 and the carrier film 2, and the dust adhering rollers 3 adsorb dust on the side surfaces of the carrier films 2 opposite to the dust adhering rollers through static electricity; each dust-binding roller 3 deviates from one side of carrier film 2 is equipped with paper-winding roller 4, paper-winding roller 4's surface with dust-binding roller 3's surface contacts, paper-winding roller 4 be used for adsorbing rather than relative dust on the dust-binding roller 3.

By arranging the dust collection assembly between the unwinding roller 1 and the coating roller along the conveying direction of the carrier film 2, dust on the carrier film 2 can be adsorbed before entering the coating roller, and when entering a coating area, the risk of adsorbing the dust again is avoided, so that the dust on the carrier film 2 is prevented from being adhered to the coating roller to influence the product quality and the processing efficiency in the process of coating glue solution.

The arrangement of a plurality of groups of dust suction assemblies can work alternately, so that at least one group of dust suction assemblies can clean the carrier film 2 in the movement process of the carrier film 2.

Referring to fig. 1, the device further includes racks 5 disposed on two sides of the extending direction of the adsorption device, each rack 5 is relatively provided with a chute 6, and the adsorption device is slidably connected in the chute 6.

The dust-binding roller 3 comprises a roller wheel and a dust-binding layer, wherein the roller wheel is arranged between the two oppositely-arranged sliding grooves 6, and the dust-binding layer is coated on the outer side of the roller wheel.

The paper winding roller 4 comprises an air expansion shaft arranged between two oppositely-arranged sliding grooves 6 and a paper roll sleeved on the air expansion shaft. The use of the inflatable shaft facilitates the replacement of the paper roll. The paper roll is a PP non-cutting paper roll.

The carrier film 2, such as a PET film, passes through the two dust-sticking rollers 3 without contact during the process of being conveyed from the unwinding roller 1 to the coating roller, and when the carrier film 2 is opposite to the dust-sticking rollers 3, the dust-sticking rollers 3 can clean both sides of the carrier film 2, so that dust on the surface of the carrier film 2 is completely cleaned.
