Abstract

The invention belongs to the technical field of plastic film heat sealing processes, and particularly relates to an improved plastic film heat-seal production process. The process includes the steps of S1, firstly, respectively winding one ends of two groups of plastic films on the surfaces of an upper group of driven winding rollers and a lower group of the driven winding rollers in a heat sealing device; and then, the other ends of the two groups of the plastic films penetrate through the lower edges of the two groups of guide rollers and an elastic pressing roller and are wound on the surface of a driving winding roller. According to the improved plastic film heat-seal production process, the contact time of a hot pressing plate and the plastic films can be prolonged, and a driving motor in transmission connection with a rotating rod and a driving motor in transmission connection with the driving winding roller do not need to be stopped in the time period, so that the driving motoris prevented from being controlled to stop when a hollow pressing plate moves downwards each time, and therefore, control components and a system are saved; and the situation that the service life ofthe driving motor can be shortened by frequently switching on and off the driving motor, and the energy consumption can be increased is avoided.

Description

Technical field[0001]The invention belongs to the technical field of plastic film heat sealing technology, and specifically is an improved process for plastic film heat sealing production.Background technique[0002]With the development of industry and the further improvement of food hygiene requirements, more and more packaging bags, shopping bags, etc. are produced in large quantities, and the indispensable for the production of plastic packaging bags is the heat sealing machine. The heat sealing machine processes the edges of the plastic film. Sealing, and then forming the plastic film into a plastic bag with three sides sealed and one side open, which can be used to hold goods.[0003]In the prior art, in the production of random-weight shopping bags for supermarkets, the edges of the plastic film are mostly kneaded by a clamping device, and then sealed by a hot pressing device, and then the plastic film is formed into a continuous, edge-sealed strip. Plastic film strips, and then i...
