Squeeze-film material separating and expelling method of plastic packaging machine and its device

Abstract

The invention relates to a film pressing substance separating and discharging method of a plastic envelope machine and a device thereof. The method is that the film rolling speed is instantly increased by increasing the film retracting motors when an inductor senses that a piece of paper passes through between an upper cover and a lower cover at the back part of the plastic envelope machine; the film pressing substance is fast separated from a parting film by a separator and is discharged by a discharging roller. The device of the invention comprises the separator, the inductor, the film retracting motors and the discharging roller; the separator can separate the film pressing substance and the parting film; the film pressing substance is easily separated from the parting film by the film retracting motors which controls the speeding up time after the inductor senses the film pressing substance, then the film pressing substance is automatically discharged by the discharge roller; the device can also include a film retracting device which winds the rest parting film after the film pressing substance is separated and an idle-bar which maintains a certain angle of the parting film and the film pressing substance to be not changed when the winding amount is excessive. The film pressing substance separating and discharging method of the plastic envelope machine and the device thereof of the invention can be used for speeding up the motors winding the parting film after the inductor senses the paper, thus leading the separation to be easy and realizing to automatically separate the parting film and the film pressing substance after a film covering substance passes through the device after being covered on the film; furthermore, the method and the device of the invention leads each edge of the film covering substance after being separated to be tidy and clear.

Description

technical field [0001] The invention belongs to the technical field of plastic sealing machines, and more specifically refers to an improvement on a method and a device for separating and discharging laminated objects of a plastic sealing machine. Background technique [0002] When the existing plastic sealing machine separates the pressing film from the diaphragm, especially for the thermal transfer film that needs to separate a film, it can only be peeled off manually, which is very inconvenient. Moreover, the manual separation is not clean and thorough, and it is very easy to leave residual membranes on the edge of the pressed film. Simultaneously, there is no special structure for pressing film material to discharge. [0003] The so-called thermal transfer film is composed of an upper film and a release film. The upper film can be peeled off from the release film to realize single-sided lamination. Contents of the invention [0004] The purpose of the present inventi...

Problems solved by technology

[0002] When the existing plastic sealing machine separates the pressed film from the film, especially for the heat transfer film that needs to separate a film, it can only be peeled off manually, which is very inconvenient

Moreover, the manual separation is not clean and thorough, and it is very easy to leave residual membranes on the edge of the pressed film.

At the same time, there is no special structure for the discharge of pressed film
