[0020] The guide unit includes a scraper 705 and a guide tube 706; the scraper 705 is fixed on the inner wall of the cleaning box 1 and contacts the outer wall of the first electrostatic roller 4, and the scraper 705 is used to scrape off the dust attached to the first electrostatic roller 4; the guide tube 706 is fixed on both sides of the first gear 601, and the guide tube 706 is a hollow tube body, which is used to provide guidance for the removal of dust; a suction hole is opened on the bottom wall of the cleaning box 1 below the guide tube 706, and the suction hole is connected to the air inlet end of the air pump 11 through the air suction pipe 10, and the air outlet end of the air pump 11 is connected to the dust collection box.

[0022] In this embodiment: when the film material 2 needs to be dusted, the film material 2 is passed through the film strip entry hole 8 into the cleaning box 1, and the drive motor 3 is started. The drive motor 3 drives the first electrostatic roller 4 connected to its output end to rotate, and the rotating first electrostatic roller 4 will synchronously drive the first gear 601 fixed at the end to rotate, and the rotating first gear 601 will drive the second gear 602 to rotate, so that the third gear 605 meshing with the outer wall of the second gear 602 rotates synchronously, then the second electrostatic roller 5 fixed at the end of the second gear 602 and the third gear 605 will also rotate synchronously, thereby clamping the film material 2 so that it enters the two second electrostatic rollers 5. At the same time, the two second electrostatic rollers 5 electrostatically absorb the dust attached to the two side surfaces of the film material 2 respectively, and one end of the transmission rod 603 eccentrically connected to the outer wall of the second gear 602 will also rotate circumferentially, and a conveying roller 604 eccentrically connected to the other end of the transmission rod 603 will also be driven to rotate. Based on the same principle, the transmission rod 603 eccentrically connected to the outer wall of the third gear 605 will also synchronously drive the other conveying roller 604 to rotate, and the two relatively rotating conveying rollers 604 convey the film material 2 between them, thereby reducing the driving unit, and the dust on the film material 2 can be cleaned synchronously while transmitting and conveying.

[0023] During the rotation of the second electrostatic roller 5, the second electrostatic roller 5 and the first electrostatic roller 4 roll against each other but in opposite directions, so that the dust on the second electrostatic roller 5 that has just contacted the film material 2 can be adsorbed and transferred by the first electrostatic roller 4, and then the outer wall of the rotating first electrostatic roller 4 will contact the scraper 705 to clean the dust, so that the contact surface of the first electrostatic roller 4 and the second electrostatic roller 5 remains clean.

[0024] When the driving motor 3 drives the first electrostatic roller 4 to rotate, the fourth gear 701 on the outer wall of the rotating shaft of the driving motor 3 will also rotate synchronously. The rotating fourth gear 701 will synchronously drive the fifth gear 702 to rotate, so that the reciprocating screw 703 fixed on the outer wall of the fifth gear 702 will rotate synchronously. Then the cleaning block 704 sleeved on the outer wall of the reciprocating screw 703 will also move axially along the inner wall groove of the cleaning box 1 under the action of the rotational force of the reciprocating screw 703. The axially moving cleaning block 704 will move along the upper surface of the scraper 705 to clean the dust accumulated on the upper surface of the scraper 705, so that the dust is pushed to the upper open end of the guide tube 706 by the cleaning block 704, and is sucked out through the guide tube 706, the exhaust pipe 10 and the exhaust pump 11, and is collected through the dust collection box, thereby achieving the purpose of automatically cleaning the dust accumulated on the first electrostatic roller 4.

[0025] Please refer to Figure 1-Figure 6 The bottom end of the cleaning block 704 is fitted with the top end of the scraper 705, and the outer wall of one side of the cleaning block 704 matches the outer wall of the first electrostatic roller 4. The outer wall of the cleaning block 704 is in a "T"-shaped structure as a whole. The interior of the cleaning box 1 is formed with a sliding groove for matching the axial movement of the protrusion on one side of the cleaning block 704. The outer wall of the reciprocating screw 703 is formed with thread grooves with different rotation directions. The inner wall of the cleaning block 704 is threadedly matched with the outer wall of the reciprocating screw 703 through a crescent; when the reciprocating screw 703 rotates, the cleaning block 704 can move back and forth along the reciprocating screw 703.

[0026] In this embodiment: through this structure, the cleaning block 704 can be driven to move back and forth along the upper surface of the scraper 705 under the action of the reciprocating screw 703, and the dust on the scraper 705 can be pushed back and forth into the guide tubes 706 distributed on both sides to complete the cleaning of the dust.
