In the production and processing of paper products, a series of processing operations such as cutting and trimming are required for cardboard, which often produces a large amount of scraps. The cardboard scraps can be produced as cardboard after further processing. Therefore, the cardboard scraps need to be recycled. Generally, the scraps need to be transported by conveyor belts and transported to collection boxes. Therefore, the conveying efficiency of cardboard scraps directly affects the progress of its collection work. The conveying efficiency of scraps is very important for its collection. At present, when conveying scraps, some glue and printing ink will remain on the scraps. When transported by the conveying device, the scraps are easy to stick to the conveyor belt, which affects the transportation of the scraps.

[0003] To this end, the Chinese invention patent with patent number CN116946655A discloses a ground transmission device for paper processing scraps that is easy to clean, including a fixed frame; a pair of drive rollers are rotatably connected to the inner side wall of the fixed frame; a conveyor belt is sleeved in the middle of the pair of drive rollers; a fixed block is fixedly connected to the side wall of the fixed frame; a connecting plate is provided on the side wall of the fixed block; a plurality of groups of bristles are fixedly connected to the side wall of the connecting plate; the bristles are symmetrically arranged, and the bristles are arranged at the end of the equipment, and contact the bristles when the conveyor belt rotates, thereby cleaning the surface of the conveyor belt, thereby effectively reducing the residue of impurities and scraps, and then cleaning the equipment to a certain extent, which is convenient for the staff to clean the equipment, reduces the workload of the staff during cleaning, and improves the transportation effect of the equipment.

[0004] However, the above-mentioned device drives the bristles to brush the surface of the conveyor belt through the connecting plate.

A worm gear 502 is fixed to the upper part of the brush rod 5, and the worm gear 502 and the worm 6 are meshingly connected.

[0036] The above scheme is adopted: through the transmission principle of the worm 6 and the worm wheel 502, when the worm 6 rotates, it is easy to drive each worm wheel 502 to rotate, and then it is easy to drive the brush rod 5 to rotate, and then it is easy to drive the plastic brush strip 501 to perform a rotational brushing operation on the scraps attached to the surface of the conveyor belt 2, which effectively improves the cleaning effect of the scraps attached to the conveyor belt 2, thereby effectively ensuring the transportation quality and efficiency.

[0037] Specifically, the lower end of the brushing rod 5 is fixedly connected with a fan blade 702 , and the fan blade 702 and the blowing pipe 7 are arranged correspondingly. The inner bottom of the cleaning box 4 is fixedly installed with a heating plate 701 .

[0038] The above scheme is adopted: the worm gear 502 drives the brush sweeping rod 5 to rotate, and then drives the fan blade 702 fixedly connected to the brush sweeping rod 5 to rotate synchronously, and the heating plate 701 is turned on to heat the inside of the cleaning box 4.
