How to adjust the knife of cold cutting bag making machine?

Adjustment method of welding knife of cold cutting bag-making machine;

Put a piece of tissue paper on the support seat, turn the big handwheel in the cabinet by hand to make the welding knife at the bottom dead center, loosen the nut, adjust the nut (note: the adjusting nut of the pull rod is basically adjusted before leaving the factory), and pull the compression degree of both ends of the tissue paper by hand until it is roughly equal. After adjustment, lock the nut to prevent loosening.

Adjustment of upper and lower cutters

1. When the upper cutter moves to the bottom dead center, it should be completely closed left and right with the lower cutter. If the right end is not completely closed, adjust the adjusting nut of the connecting rod to lower the upper cutter slightly. After adjustment, tighten the upper nut.

2. After using for a period of time, when the gap between the plug iron increases, it should be adjusted immediately. At this point, loosen the nut first, gently push the adjusting screw of the inserted iron into the appropriate gap, and check with a feeler gauge. The gap should not be greater than 0.02 mm. After adjustment, tighten the nut.

3. Adjust the adjusting connecting screw of the upper cutter. There is a small gap between the initial cutting end of the upper cutter and the lower cutter to prevent the cutter from colliding and damaging it.
