AI Technical Summary

Technical Problem

Existing feeding auxiliary devices are insufficient in handling the clumping of raw materials in large packages and efficiently compressing empty bags, leading to production stoppages and space occupation issues.

Method used

An automatic bag-opening and feeding auxiliary device was designed, which includes a crushing mechanism and a squeezing mechanism. The crushing roller crushes the lumpy raw materials, and the electric telescopic rod and squeezing plate squeeze the packaging bag to achieve smooth entry of raw materials and storage of the bag.

Benefits of technology

This effectively avoids production stoppages caused by clumping, improves production efficiency, reduces the space occupied by packaging bags, and ensures the uniformity of raw materials and the stability of subsequent production quality.
