Problems solved by technology

[0002] When the existing air cushion machine is making cushion airbags, the radius of the roll film gradually decreases during the operation of the air cushion machine, and the amount of roll film delivered to the air cushion machine per unit time will increase, which will cause the roll film to be in the air cushion. The tension at the guide bar of the air cushion machine decreases, and even the film rolls will be stacked in the front section of the air cushion machine, which will affect the normal inflation, heat sealing, and transmission, and even cause safety accidents, and will also affect the inflation and heat sealing effects, reducing the work efficiency

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0018] Figure 1 to Figure 3 Schematically shows the structure of an automatic membrane tension adjustment device and an air cushion machine including it according to an embodiment of the present invention.

[0019] Such as Figure 1 to Figure 3 As shown, an automatic membrane tension adjustment device includes a friction plate 1 , a roller 2 , a friction column 3 , a compression spring 4 , a swing lever 5 , a compression lever 6 and a bracket 7 . In addition, the film tension automatic adjusting device may also include a fixed frame 8 , a tension spring 9 , an adjusting bolt 82 , a fixed box 10 and a rotating shaft 11 .

[0020] Such as figure 1 As shown, one end of the drum 2 is installed on the top of the bracket 7, and the drum 2 is rotatably connected with the bracket 7, that is, the drum 2 can rotate.

[0021] Such as figure 1 As shown, the frictio...

Abstract

The invention discloses a membrane tension automatic adjustment device and an air-cushion machine containing the same. Along with operation of a system, the radius of a coiled membrane is reduced gradually, and under the same friction force, the membrane tension is enlarged, and the membrane putting speed is reduced; the right end of a swing rod swings upwards, the left end of the swing rod swings downwards, the compression amount of a compressed spring is reduced, and the friction force between a friction pillar and a friction disc is reduced; the rotation speed of a roller is increased, the membrane putting seed is increased, the tension of the membrane at a compression bar is reduced, and the balanced state is reached; when the tension of the membrane is reduced, the right end of the swing rod swings downwards, the left end of the swing rod swings upwards, the compression amount of the compressed spring is increased, the friction force between the friction pillar and the friction disc is increased, the rotating speed of the roller is lowered, the membrane putting speed is reduced, the tension of the membrane at the compression bar is enlarged again, and the balanced state is reached again; and the coiled membrane always operates under relatively constant tension, the tension of the coiled membrane at the compression bar is adjusted automatically, and it is guaranteed that the membrane amount of the coil membrane conveyed to the air-cushion machine in unit time can maintain a relatively constant range.

Description

technical field [0001] The invention relates to an automatic adjustment device for film tension, and also relates to an air cushion machine including the automatic adjustment device for film tension. Background technique [0002] When the existing air cushion machine is making cushion airbags, the radius of the roll film gradually decreases during the operation of the air cushion machine, and the amount of roll film delivered to the air cushion machine per unit time will increase, which will cause the roll film to be in the air cushion. The tension at the guide bar of the air cushion machine decreases, and even the film rolls will be stacked in the front section of the air cushion machine, which will affect the normal inflation, heat sealing, and transmission, and even cause safety accidents, and will also affect the inflation and heat sealing effects, reducing the work efficiency. Contents of the invention [0003] The object of the present invention is to provide an aut...
