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 both the sealing and cutting packaging machine and the sealing and cutting winding machine can reduce the usage amount of film.

However, in the operation process of the sealing and cutting packaging machine and the sealing and cutting device in the sealing and cutting winding machine, the film is conveyed by the film placing motor, the film is tensioned by the swing rod assembly, the film angle is detected by the sensor to control the operation of the film placing motor, the structure is complex, and the control difficulty is high. And when the film releasing motor rotates too fast, the film is easy to be tensioned in time, and the film is reversely rolled onto the film roll. In addition, the swing rod assembly always generates certain tension for tensioning the film, so that the welding position between the upper film and the lower film is easy to break.

SUMMERY OF THE UTILITY MODEL
