Description

Technical Field

[0001] The utility model discloses a switching mechanism, belongs to the technical field of workpiece conveyor belts, and specifically relates to a fast switching mechanism. Background Art

[0002] A workpiece conveyor belt is a mechanical device used to transport items or products on a production line. It usually consists of a continuous belt-like structure that can move along a set path and transfer items from one location to another during operation. These conveyor belts can be made of rubber, plastic or metal, depending on the environment in which they are used and the type of items being transported. Workpiece conveyor belts are widely used in various fields in the manufacturing industry, such as automobile manufacturing, food processing, packaging industry, etc., to improve production efficiency and reduce labor costs.

[0003] However, the workpiece conveyor belt in the prior art can only convey forwards, and cannot convey left and right. At the same time, the traditional workpiece conveyor belt can only convey bows and arrows of fixed specifications. When there are different workpieces, the staff needs to stop the machine to manually adjust or select other conveyor belts, which results in low transmission efficiency. Utility Model Content
