AI Technical Summary
Plastic bags are prone to displacement when conveyed on guide rollers, deviating from the designated guide roller track, resulting in unstable slitting.
Limiting components are used to limit the two sides of the plastic bag. By cooperating with the limiting plate and the deflection head, the position of the limiting components can be adjusted to accommodate plastic bags of different widths. The electric push rod is controlled by the telescopic motor to drive the slitting blade for slitting.
This ensures the stability of plastic bags during transportation, prevents displacement, and guarantees the accuracy and consistency of cutting.
