Embodiment Construction

[0016] The specific embodiment of the present invention sees Figure 2 to Figure 14 , including the following steps:

[0017] 1) Cutting the M-shaped cylindrical film: When the M-shaped cylindrical film on the old film roll at the working position (A) is about to be used up, the film feeding unit (4) stops conveying the cylindrical film, and the cutting and heat-sealing unit (2 ), the compression blocks (2-3) located on the upper and lower sides of the cylindrical membrane compress the cylindrical membrane back and forth, and the zigzag cutter (2-4) protrudes from the middle of the front and rear compression blocks (2-3) , cutting the cylindrical film into old film (1) and waste film (3);

[0018] 2), switch the cylindrical film roll: move the new film (5) in the storage position (B) laterally to the working position (A), and at the same time, the film roll core (6) and the waste film (3) in the original working position (A) ) traverse to the storage position (C);

Abstract

The invention relates to a method for automatically replacing an M-shaped cylindrical film roll. The method aims to solve the problem that the conventional method cannot realize automatic connection and replacement of the M-shaped cylindrical film roll. The method comprises the following steps of: (1) cutting off an M-shaped cylindrical film; (2) switching a cylindrical film roll; (3) opening a cylindrical old film; (4) inserting a new film into the old film; (5) thermally sealing the new film and the old film; and (6) placing the obtained film roll and clearing up a next film roll. The technical method of the invention can realize the automatic connection and replacement of the M-shaped cylindrical film roll, and the symmetric plane of the upper corrugated edge and the lower corrugated edge of the M-shaped cylindrical film after the connection can be coplanar with the symmetric plane of the upper corrugated edge and the lower corrugated edge of the M-shaped cylindrical film roller before the connection so as to automatically adapt to the requirements of packaging machines and improve the working efficiency of the packaging machines.

Description

technical field [0001] The invention relates to a method for automatically connecting M-shaped cylindrical films and automatically replacing M-shaped cylindrical film rolls, belonging to the technical field of packaging. Background technique [0002] With the further improvement of the performance of the FFS packaging machine, the M-shaped cylindrical film rolls used in the production of packaging bags need to be replaced frequently, and the equipment operation time delayed by replacing the cylindrical film rolls will reduce the production capacity of the packaging machine. Therefore, a device for automatically changing the M-shaped cylindrical film roll is needed, so as to reduce the time required for changing the film roll and improve the production capacity of the equipment. Patent document CN85101025A discloses a device for automatically switching film rolls, but this method is only suitable for the connection and replacement of single-layer films; patent document CN1150...
