Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a material blocking prevention device for a material drop port of a belt conveyor. Background Art

[0002] Belt conveyor is a kind of machinery that transports materials in a friction-driven and continuous manner. It can form a material conveying process from the initial feeding point to the final unloading point on a certain conveying line. It can convey both loose materials and finished items. It is the most commonly used high-efficiency continuous transportation equipment on the tobacco silk production line in the cigarette factory. It is often used to transport tobacco raw materials such as leaves, leaf shreds, and stem shreds. The tobacco silk production line adopts an assembly line production method, which has high requirements for production continuity. Failure at any point will cause the production process to be interrupted, which has a great impact on product quality and raw material consumption.

[0003] However, large pieces of tobacco that have not been fully moistened often appear after the loosening machine. They are easily stuck at the material outlet when transported by the belt conveyor. At this time, the belt conveyor is still running with materials. If it is found that it is not in time, a large amount of material will accumulate at the head, causing the belt conveyor to be crushed. In serious cases, the belt will be torn or the equipment will be damaged, seriously affecting the sustainability of production organization and product quality. At present, an observation point is set up after the loosening machine, and a special person is arranged to check and timely find large pieces of tobacco that have not been loosened. They are manually loosened and then poured into the belt conveyor. Not only is the labor intensity high and the work efficiency low, it is difficult to ensure the complete removal of tobacco pieces, and there are certain safety hazards in picking during the startup process, which has a great impact on the refined management of the production site.
