[0002] The re-drying machine is a special equipment for drying, cooling and rehumidifying tobacco leaves. Its conveying part is mainly composed of a conveyor belt (mesh belt) with mesh and a transmission chain that drives the mesh belt to circulate. Since the temperature and humidity inside the re-drying machine are relatively high and the tobacco leaves themselves contain a lot of oily substances, the chain is prone to adhere to tobacco oil, dust, tobacco leaf fragments and other substances during the re-drying process, resulting in poor chain operation, loud noise and easy wear, so it must be cleaned regularly.

[0003] At present, the chain is usually cleaned by a handheld air pressure spray gun, which is not only labor-intensive and inefficient, but also easily affected by factors such as the operator's proficiency and technical experience. In addition, it can only clean the dust on the surface of the chain, while the smoke and oil stains adhering to the gaps in the chain are difficult to remove.

[0004] In order to overcome the above-mentioned defects of manual cleaning, the utility model patents named "An automatic cleaning device for the side chain of a tobacco re-roasting machine (CN216415999U)" and "A custodial maintenance device for improving the maintenance efficiency of the large chain of a re-roasting machine (CN210230855U)" respectively disclose chain cleaning devices installed on the re-roasting machine production line. Although they reduce labor intensity and improve cleaning efficiency, they have the following defects:

[0005] 1) It can only clean the dust layer on the surface of the chain, but cannot clean the oil stains on the back and gaps of the chain;

[0006] 2) No dust prevention measures were taken, and the mesh belt and the surrounding environment were easily contaminated during the cleaning process, affecting the quality of the tobacco products;

[0007] 3) It is a fixed structure and can only clean one redrying production line, and cannot meet the cleaning needs of multiple redrying production lines. Utility Model Content
