Description

Technical Field

[0001] The utility model relates to the technical field of tobacco manufacturing, in particular to an automatic regulating device for a proximity switch. Background Art

[0002] In the automated production process of cigarettes, proximity switches are often used to locate the position of the material distribution trolley, especially in the storage cabinets and material distribution trolleys for reciprocating material distribution. The proximity switches are installed on the walking track at the corresponding position of the material distribution cabinet, and the left limit proximity switch and the right limit proximity switch are respectively set on the walking track corresponding to the two sides of the material distribution cabinet to realize the reciprocating movement of the material distribution trolley.

[0003] In the production process, operators often need to adjust the distance between fabrics according to the actual situation of the fabrics, which usually means adjusting the position of the proximity switch on the walking track. However, the current process of adjusting the position of the proximity switch is quite cumbersome and inefficient. Specifically, every time the position of the proximity switch needs to be adjusted, it needs to be removed first and then reinstalled to the new position. Since each installation needs to ensure that the proximity switch is installed firmly and reliably, and it often takes multiple attempts and adjustments to find the best installation position, this makes the work of adjusting the proximity switch position cumbersome and time-consuming. Therefore, the current way of adjusting the position of the proximity switch obviously needs to be improved. Utility Model Content
