AI Technical Summary
Existing automatic bag-opening devices often fail to completely cut through plastic bags, resulting in plastic residue remaining inside.
The first and second cutters are arranged in parallel. The slider on the connecting arm is driven by the drive mechanism to reciprocate on the guide rail, so that the cutters can cut the material bag at the same time and ensure that the plastic particles can flow out smoothly.
It completely tears plastic bags, preventing plastic residue, and has a simple and practical structure.
