[0040] like Figure 1-Figure 5 As shown, in this embodiment, the belt conveyor edge pressure unpowered cleaning device is used to clean the tobacco material on the belt conveyor. The belt conveyor includes a conveyor belt 100 and a side plate 200. The side plate 200 is arranged beside the conveyor belt 100, and the conveyor belt 100 is arranged in an inclined manner. The belt conveyor edge pressure unpowered cleaning device includes a bracket 1, a brush 2 and a suction cup 3. Among them, the bracket 1 is rolled on the side plate 200, the brush 2 is slidably arranged on the bracket 1, the brush 2 is used to clean the pressure edge of the conveyor belt 100, and the suction cup 3 is arranged on the brush 2. The suction cup 3 can slide relative to the bracket 1 along the height direction of the side plate 200 so that the brush 2 is in a cleaning state or a return state. When the brush 2 is in a cleaning state, the suction cup 3 is adsorbed on the conveyor belt 100, and the brush 2 is close to the pressure edge of the conveyor belt 100. When the brush 2 is in a return state, the suction cup 3 is separated from the conveyor belt 100 under the longitudinal force of the conveyor belt 100.

[0041] Specifically, the bracket 1 includes a moving part and a connecting part, the moving part is rollingly arranged on the top surface of the side plate 200, and the connecting part is vertically arranged on the moving part and located above the conveyor belt 100. The brush 2 and the suction cup 3 are both arranged at the connecting part of the bracket 1, the brush 2 is used to clean the connection between the conveyor belt 100 and the side plate 200, that is, the pressure edge of the conveyor belt 100, the suction cup 3 is made of a flexible material, the bottom of the suction cup 3 is flush with the bottom of the brush 2, the suction cup 3 can absorb the conveyor belt 100 to drive the bracket 1 to move synchronously, and the brush 2 can clean the materials on the pressure edge of the conveyor belt 100 onto the conveyor belt 100. The working process of the unpowered cleaning device for the pressure edge of the belt conveyor is as follows: manually press the suction cup 3, the suction cup 3 slides relative to the bracket 1 along the height direction of the side plate 200 and is adsorbed on the surface of the conveyor belt 100, at the same time, the brush 2 slides synchronously with the suction cup 3 relative to the bracket 1 and is tightly attached to the pressure edge of the conveyor belt 100, the brush 2 is deformed and generates interaction force with the pressure edge, the brush 2 is in a cleaning state, and under the conveyance of the conveyor belt 100 and the adsorption force of the suction cup 3, the brush 2 and the pressure edge of the conveyor belt 100 generate sliding friction, and the tobacco material accumulated on the pressure edge is swept onto the conveyor belt 100. When reaching the end of the conveyor belt 100, under the longitudinal force of the conveyor belt 100, the suction cup 3 is deformed and leaks, causing the negative pressure in the cavity of the suction cup 3 to disappear, and the suction cup 3 is separated from the conveyor belt 100. At the same time, the brush 2 changes from a close-fitting edge pressing state to a lightly touching edge pressing state. At this time, the brush 2 is in a return state, and the brush 2 slides from the end of the conveyor belt 100 to the initial position under the action of gravity. The brush 2 cleans the accumulated tobacco material on the edge pressing to the conveyor belt 100 for the second time, forming a reciprocating cleaning. The reciprocating cleaning operation of the conveyor belt 100 can be achieved without additional power, which is suitable for the edge pressing cleaning of the climbing belt conveyor in the silk workshop to avoid the accumulation of tobacco material to ensure the integrity of the leaf group formula. At the same time, no secondary equipment modification is required, and the cost is low.
