AI Technical Summary
In packaging bag film cutting devices, the impact force between the film cutting steel blade and the film cutting base frame is difficult to buffer, which makes the film cutting steel blade easy to damage, affecting the cutting ability and cutting accuracy.
A packaging bag film cutting device was designed. A feeding motor drives the feeding roller to rotate, and an electric push rod pushes the fixed pressure plate to descend and press and fix the film material. A cutting motor drives the threaded rod to rotate, so that the moving block moves along the guide slide and the cutting blade moves along the cutting groove to avoid hard impact. The fixed pressure plate fixes the film material to prevent position displacement.
It effectively reduces the wear of the cutting blade, ensures cutting accuracy, avoids cutting position deviation, and improves the service life and cutting quality of the film cutting device.
