1. Whether the front part is on the center line is the reference of the front part of the elephant trunk and the film drawing wheel of the packaging machine. The former needs to be in the middle of the film drawing wheel. If it is not in the middle of the film drawing wheel, loosen the relevant screws and adjust it left and right. The bag over there has many wrong sides, so move the former over there.

2. Look at the parallelism of the shaper from the side, that is, from the side, the trunk shaper should be parallel to the longitudinal sealing veneer. This operation means that the packaging bag will not get stuck in the pocket, can pass through the molding machine smoothly or will not fold the packaging bag, and at the same time ensure the sealing stability of the packaging bag. The main operation is to loosen the relevant fastening screws, and at the same time, adjust the distance between the molding machine and the longitudinal sealing veneer to 7 mm.
