AI Technical Summary
The feeding port of existing quantitative packaging electronic scales is prone to clogging during the shrinkage process, especially the symmetrical opening design, which causes clogging by irregular granular materials.
Multiple horizontally movable baffles are arranged around the feed tube. The baffles are driven to move horizontally by a drive unit to form a square opening instead of a narrow opening, thus avoiding blockage.
It effectively avoids clogging at the feed inlet, improves the accuracy and speed of feeding, and ensures the normal feeding of irregular granular materials.
