Rolling type film heat sealing machine

Abstract

The invention discloses a rolling type film heat sealing machine which comprises a feeding roll and further comprises a heat sealing roll assembly. The heat sealing roller assembly is used for conducting heat sealing on a film fed by the feeding roll. The heat sealing roll assembly comprises a first traction roll, a second traction roll and a heat sealing roll arranged between the first traction roll and the second traction roll. The first traction roll and the second traction roll are arranged in parallel. The heat sealing roll is driven by a transmission mechanism to rotate and is further provided with an electric resistance wire. The electric resistance wire extends to the other end of the heat sealing roll from one end of the heat sealing roll to be connected with an external power source. The rolling type film heat sealing machine has the beneficial effects that the maintenance rate is low, the heat sealing stability is good, noise is small and a manufactured film bag is convenient to carry and easy to open.

Description

Technical field [0001] The present invention relates to the technical field of thin films, in particular to a rolling film heat sealing machine. Background technique [0002] The film is a thin and soft transparent sheet. Made of plastic, adhesive, rubber or other materials. The scientific explanation of polyester film is: a two-dimensional material formed by atoms, molecules or ions deposited on the surface of a substrate. Examples: optical films, composite films, superconducting films, polyester films, nylon films, plastic films, etc. Films are widely used in electronics, machinery, printing and other industries. [0003] The production process of the film bag includes the following steps: (1) The resin masterbatch is made into a film by a film blowing machine; (2) It is wound by a winder and cut to a set length by a film cutting machine; (3) A heat seal is used The machine is heat-sealed; (4) Cut out a film bag with the bottom side heat-sealed, both sides sealed, and the top...

AI Technical Summary

Problems solved by technology

[0004] The traditional heat sealing machine is a downward-pressing heat-sealing device, and the downward-pressing heat-sealing device performs a downward movement for a long time, which will fail and require frequent maintenance

Moreover, in the process of heat sealing under pressure, a certain amount of stamping is caused to the film, and the stability of heat sealing needs to be improved.

In addition, the press-type heat sealing machine is noisy when it is working.

[0005] The film bag made by heat-sealing and cutting of the traditional film has the shape of the opening, which is inconvenient to carry after installing the article; in addition, this kind of film bag is not easy to open
