AI Technical Summary

Technical Problem

Existing PET sheet winding devices are not convenient for weighing, making it difficult for operators to keep track of the winding weight in a timely manner. In addition, dust easily falls on the surface of the lead screw, affecting the continuity of work.

Method used

An insertion hole and extension rod are set on the base plate to connect the weighing plate and the weight sensor. The weight sensor measures the winding weight, and a cylinder is used instead of a lead screw to move the positioning seat, thereby improving the weighing accuracy and work efficiency.

Benefits of technology

It enables real-time monitoring of the PET sheet winding weight and stable movement of the positioning seat, improving the functionality and efficiency of the device and reducing the frequency of downtime for dust cleaning.
