Film-feeding and film-cutting mechanisms of film packager

Abstract

The invention discloses film-feeding and film-cutting mechanisms of a film packager, which comprises a film roll supporting component, a film-tension component and a film-cutting transmission component according to the sequence of material transmission direction, wherein when one film roll in the film roll supporting component is in operation, another film roll is standby, and when the working film roll is used up, the spare film roll is enabled; an action of changing the film roll conveniently and efficiently can be finished by connecting the front end of the spare film roll to the end of the film roll in operation; the film-tension component comprises a frame, a transitional wheel and a tension-adjusting device, wherein the film-tension component is used as the transition between the film roll supporting component and the film-cutting transmission component, thus adjusting the tension strength between the two components; and the film-cutting transmission component comprises a film-cutting part and a film-feeding part, wherein the film-cutting part of the film-cutting transmission component is arranged at one end of the conveyor belt as an input end, which is connected to the film-tension component, thus lowering the height of the film-cutting part in an integral level and being convenient in maintenance.

Description

technical field [0001] The invention relates to a film packaging machine, especially a film feeding and film cutting mechanism in the film packaging machine, which is used to complete the film feeding and film cutting in the film packaging machine. Background technique [0002] In order to save cartons, manufacturers use heat shrinkable film packaging machines to pack bottled products. When packaging, the bottles are divided into groups and sent to the film cutting position of the packaging machine by the conveyor and push rod. The plastic film is used to wrap the bottle group by the film cutting device, then cut, and at the same time glue the cut, and then pass through The baked plastic film is heat-shrunk to complete the package. At present, the film packaging machine mainly includes a film feeding mechanism, a film cutting mechanism, and a film packaging mechanism. The film feeding mechanism is equipped with a film roll, which can continuously provide plastic films for ...

AI Technical Summary

Problems solved by technology

At present, the film packaging machine mainly includes a film feeding mechanism, a film cutting mechanism, and a film packaging mechanism. The film feeding mechanism is equipped with a film roll, which can continuously provide plastic films for the film packaging mechanism, so that it can realize automatic production. Generally, there is only one film roll in the film mechanism. After the film roll is used up, it needs to be replaced before the production can continue. This process takes a certain amount of time and reduces the production efficiency; the film cutting mechanism is used to transport the film feeding mechanism. The plastic film is cut in equal parts. Due to the instability of the motor in the film feeding mechanism, it is inevitable that there will be different speeds during the film feeding process, so that the tension of the plastic film between the film feeding mechanism and the film cutting mechanism is not stable. Uniform, sometimes even the film will be broken, which seriously affects the production efficiency
