Description

Supplementary seal is cut and is drawn membrane mechanism

Technical Field

The utility model relates to an supplementary seal is cut and is drawn membrane mechanism.

Background

When the cigarette carton is shipped, a plurality of cigarette cartons need to be packaged together for distribution, for example, a batch of cigarette cartons are sent from a factory to a retail outlet such as a canteen. In the prior art, there are several methods for wrapping a strip cigarette with a film: the first packaging method is to wrap the cigarette in strip form by heat shrinking of PE film; a second method of packaging is to use a wrapping machine to form a stack of cigarette strips for shipping (e.g., patent 2017205232023 discloses a film roll packaging machine for cold-pack cigarette strips); the third packaging method is to wrap the film of the strip cigarette by using a seal-cutting packaging device.

For example, a sealing and cutting packaging machine for cold packaging of cigarette carton and a sealing and cutting winding machine for cold packaging of cigarette carton disclosed in chinese patent No. 2018213982168 and No. 2018213988554 are both packaging devices, and can be used in the third packaging method, and the sealing and cutting packaging machine and the sealing and cutting winding machine can reduce the usage amount of films by packaging through the sealing and cutting devices.

However, when the number of the cigarettes to be packaged is less, such as one, two, three, etc., the cigarettes are pushed into the sealing and cutting equipment through the external pushing plate, the stress of the film is concentrated, the film is easy to break, the film is concentrated and pulled to the stress side to form a notch, the film packaging is easy to loose, and the position of the corresponding notch of the cigarettes to be packaged next time is exposed, so that the packaging is incomplete. Further, the film which is intensively pulled against one side may form a multi-layer wrinkle, so that stable welding cannot be performed and film breakage easily occurs. In addition, the posture of the wrapped cigarettes in strips is also varied due to stress problems. Fig. 1 is a simplified schematic diagram showing a strip of cigarettes 15 packaged by the sealing and cutting device, fig. 2 is a schematic diagram showing various postures of the strip of cigarettes 15 when the strip of cigarettes 15 is packaged by the sealing and cutting device, fig. 3 is a schematic diagram showing that the film 18 is pulled back to one side due to concentrated force when the strip of cigarettes 15 is packaged by the sealing and cutting device, and a notch is formed on the other side of the film 18.
