Background

At present, in the tobacco processing industry, a large number of belt conveyors are required to convey tobacco shreds, and before conveying the tobacco shreds, substances such as water, spice and the like are required to be added into tobacco raw materials, and have strong viscosity, so that the tobacco shreds can adhere to a conveying belt. When two belt conveyors are used in a crossed and overlapped mode, although the conveying belt of the upper belt conveyor exceeds the overlapping area of the lower belt conveyor, part of tobacco shreds adhered to the upper belt conveyor fall out of the range of the lower belt conveyor under the action of gravity, so that the sanitation condition and the cleanliness of a cigarette production site are seriously affected, the cleaning time of workers is prolonged, and a certain amount of tobacco shreds are lost.

For example, china patent (application publication number: CN 113716293A) discloses an elastic scraper for cleaning a conveyor belt, which comprises a supporting frame and two groups of supporting mechanisms. The supporting mechanism comprises a supporting plate, an adjusting plate, a first square tube and a second square tube, and a plurality of connecting holes are formed above the supporting plate, so that the two supporting plates are respectively fixed on two sides of the conveying belt; the below of backup pad is equipped with a plurality of regulation holes, and the regulating plate passes through bolted connection with the regulation hole, and first side pipe is fixed on the relative medial surface of regulating plate, and second side pipe box is established on first side pipe, and is equipped with the rubber strip between the lateral wall of first side pipe and the inside wall of second side pipe, and the upper surface at two second side pipes is lapped respectively at the both ends of support frame, is equipped with the scraper blade on the support frame, is equipped with the rubber on the side of the surface of scraper blade laminating conveyer belt. The scraper blade and the cleaned conveyer belt are tightly attached together by utilizing the elasticity of the scraper blade, so that sundries on the conveyer belt can be cleaned well, and the conveyer belt is not damaged.

However, in the above proposal, although the scraping plate can clean the tobacco shreds on the conveying belt, the tobacco shreds adhered on the conveying belt are easily accumulated at the rubber skin on the scraping plate, the appearance quality of the accumulated and compressed tobacco shreds is affected, and a certain amount of tobacco shreds are lost. And the elasticity that adopts the rubber strip between the lateral wall of first side pipe and the inside wall of second side pipe lets between scraper blade and the conveyer belt tight laminating be in the same place, when having the foreign matter on the conveyer belt, the rubber strip can take place plastic deformation under long-time compression or high pressure effect, leads to being difficult to restore to original state after the deformation, leads to the position of scraper blade to produce certain displacement.
