Description

Technical Field

[0001] The present invention relates to the technical field of cigarette equipment, and more specifically, to a tobacco equipment belt deviation warning device. Background Art

[0002] In the production process of tobacco shreds, whether it is tobacco leaf flow control, precise formula proportioning or uniform material transportation, the conveyor belt is indispensable. The normal operation of the conveyor belt is the basis of tobacco shred production. The motor with a reducer drives the transmission gear at the bottom of the conveyor belt through the chain to realize the normal operation of the belt conveyor.

[0003] At present, due to uneven material distribution on the belt, vibration and deviation of the belt tensioner and other problems, the belt will deviate after a certain period of time. The traditional method of detecting belt deviation is to implant a metal segment in the belt. When the metal segment approaches the magnetic switch, a high-level signal will be generated. However, this method not only increases the production cost of the belt, but also causes the metal segment of the belt to wear out severely over time, resulting in detection failure, causing the belt to deviate seriously or even break.
