Film cutting assembly structure facilitating bag film lap joint

Abstract

The invention discloses a film cutting assembly structure facilitating bag film lap joint, the structure comprises a film cutting fixing plate, a push-pull clamp fixing plate, a film cutting air cylinder fixing plate, a cylinder, a film cutting plate, a push-pull clamp fixing plate, a lead screw and an adhesive tape fixing plate, the film cutting plate is fixed on the film cutting fixing plate, a blade opening position is arranged on the film cutting plate, a film cutting roller assembly part is arranged at the joint of the film cutting fixing plate and a film winding roller, the film cutting air cylinder fixing plate is arranged on the inner edge side of the film cutting plate, an air cylinder is installed on the film cutting air cylinder fixing plate and connected with an air cylinder film pressing column, the air cylinder is further connected with and controls the lead screw and a long lead screw, the film cutting fixing plate is fixedly connected with the adhesive tape fixing plate, an adhesive tape fixing shaft is arranged on the adhesive tape fixing plate, the film winding roller is arranged on the upper portion of the film cutting plate, and a push-pull clamp fixing plate, a push-pull clamp upper fixing plate and a push-pull clamp pneumatic clamp are arranged on the inner side of the film cutting fixing plate. The accuracy of the adhesion position of a new bag film and an old bag film can be effectively controlled, the bag film replacement time is shortened, and bag film waste is reduced.

Description

technical field [0001] The invention relates to a packaging mechanism component, in particular to a film-cut assembly structure which facilitates overlapping of bag films. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the demand for various convenience foods has also increased. Vacuum packaging machines are one of the fastest-growing packaging machinery and have broad development prospects. The air nozzle is placed in the packaging bag of the packaged object, the air is evacuated, the air nozzle is withdrawn, and then the sealing is completed, and the packaging bag is made of a bag film. During the operation of the existing packaging machine, the bag film is used. , the replacement of the bag film is cumbersome and time-consuming, which greatly reduces the overall working efficiency of the packaging machine. [0003] At present, when replacing the bag film, the existing vertical back-seal packaging machine on th...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the vertical packaging machine existing in the prior art uses a knife to cut the old bag film when replacing the new bag film, since no pressing device is provided, the film alignment will often be caused when the adhesive tape is re-adhesive, and the bag is pulled There will be a position shift when the film is filmed, and multiple adjustments are required to adjust the position. When replacing the bag film, it will cause problems such as long replacement time of the bag film and waste of the bag film.
