Description

An anti-backflow device for a pipeline

technical field

The invention belongs to the technical field of assembly line accessories, and in particular relates to an anti-backflow device for an assembly line .

Background technique

The assembly line is widely used in the modern industrial production of textiles and garments, plastic products, electronic appliances, automobile assembly, etc., that is, the assembly parts are placed on the transmission belt of the assembly line, processed by various stations, and finally assembled into a complete The product. The assembly line plays an important role in industrial production. Optimizing the assembly line is directly related to product quality and production efficiency, and is a topic that enterprises have to pay attention to. The assembly line is an effective combination of man and machine, which fully reflects the flexibility of the equipment. It generally includes traction parts, load-bearing components, driving devices, tensioning devices, redirecting devices and supporting parts, and is realized by the transmission mode of the drive shaft flow. When installing the assembly line, the flow direction of the assembly line is generally determined according to the production situation on the factory site. However, the large conveying capacity of the assembly line, the long transportation distance, and the large number of personnel involved in the operation make it inevitable that reverse transmission will occur during normal operation. For example: due to The inertia of the product stuck in the conveyor belt, or the sudden failure of the redirection device, or other human factors may cause the assembly line to go backwards. As long as a process goes retrograde, it will cause the entire assembly line to go retrograde, which will lead to production chaos and affect the production progress. Moreover, due to the long distance of the assembly line, it is often difficult to quickly troubleshoot where the assembly line fails.

Therefore, whether to provide an anti-backflow device that can effectively prevent the reverse transmission of the pipeline is a technical issue to be solved in the industry at present .
