The heat sealing and cutting all-in-one machine disclosed by the invention has a simple structure, and heat cutting and cutting procedures are combined, so that the machining efficiency is extremely improved.

Description

technical field [0001] The invention relates to plastic bag processing equipment. Background technique [0002] The plastic bag sealing machine refers to the machine that seals the container after the packaging container is filled with products. Its working principle is to use plastic bags or composite bags made of good thermoplastics. Generally, the sealing is directly heated and mechanical pressure is applied. , to fuse the seal. In the processing of some plastic bags, the remaining edge of the bag must be cut off after sealing. The traditional method is to first seal the plastic bag with a sealing machine, then remove the plastic bag, and use a cutting device to cut off the remaining edge of the plastic bag. Cutting the edge of the bag not only increases the labor intensity of people, but also has low work efficiency. Contents of the invention [0003] The present invention intends to provide an integrated heat-sealing and cutting machine for plastic bags that can sim...
