Description

Double station cutting and sealing integrated equipment for plastic bag production

technical field

The utility model belongs to the technical field of plastic bag production equipment, in particular to a double-station cutting and sealing integrated equipment for plastic bag production.

Background technique

Plastic bag cutting and sealing machine is an indispensable processing equipment in the continuous production of plastic bags. The integrated cutting and sealing machine uses the heat sealing mechanism to complete the heat sealing to form the bottom of the plastic bag, and then uses the cutter mechanism to cut the plastic bag. In the existing cutting and sealing integrated machine, the motor drives the driving roller to pull and transport the coil, and the coil rotates and releases the film material due to the action of the traction force. Since the coil is passively rotated, under the action of inertia, the speed at which the coil releases the film material is inconsistent, resulting in inconsistent tension of the film material during the conveying process, which in turn causes the heat sealing mechanism and the cutter mechanism to be unable to accurately cut and cut according to the set requirements. The consistency of the product cannot be guaranteed when the plastic bag of the required length is heat-sealed. Too much film material is released from the roll, and the hanging film material is easy to be stained or even stuck on the machine. In particular, it is difficult to ensure the consistency of the product for the integrated cutting and sealing machine with dual-station settings.
