Opposite-cutting adjusting device for bag making machine

Abstract

The invention relates to an adjusting device, particularly relates to an opposite-cutting adjusting device for a bag making machine, and belongs to the technical field of bag making machines. The opposite-cutting adjusting device for the bag making machine comprises a right connecting plate support and a left connecting plate support, wherein a second right fan-shaped gear and a second left fan-shaped gear are arranged on an adjusting strut; the outer side of the left connecting plate support is connected with a left supporting plate through a bolt; the inside of the left supporting plate is slidably connected with a left adjusting screw; one end of the left adjusting screw is provided with a first left fan-shaped gear which is meshed with the second left fan-shaped gear; and the other end of the left adjusting screw is in threaded connection with the left end of a supporting shaft. The outer side of the right connecting plate support is connected with a right supporting plate through a bolt; the inside of a right supporting plate is slidably connected with a right adjusting screw; one end of the right adjusting screw is provided with a first right fan-shaped gear meshed with the second right fan-shaped gear; and the other end of the right adjusting screw is connected with the right end of the supporting shaft through a bolt. The travel of an upper film and the travel of a lower film can be adjusted to be consistent; the production efficiency and the bag making quality are improved; and adjustment is convenient, quick and effective.

Description

technical field [0001] The invention relates to an adjusting device, in particular to a half-cut adjusting device of a bag making machine, which belongs to the technical field of bag making machines. Background technique [0002] When the bag making machine is processing single-feeding three-side-sealed bags, the film is folded in half by a triangular plate and cut into two pieces of film. After the half-cut film passes through the tension correction device, the upper and lower films are joined together to complete the vertical sealing and horizontal sealing heat sealing, and finally cut off by the cutter. After half-cutting, the upper and lower films must travel the same distance when moving to the tension correction device. This distance is relatively long, and at the same time, the error caused by the tension part to the film will easily cause the strokes of the upper and lower films to be inconsistent. affect normal production.
