Description

Technical Field

[0001] The utility model relates to the technical field of bag making, in particular to an anti-deviation punching device for a bag making machine. Background Art

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products. The bag making machine needs to punch holes in the plastic packaging bags during the bag making process.

[0003] A Chinese patent (application number: CN201721278138.3) discloses "a punching device for a bag making machine", which pushes a sliding support rod so that the sliding support rod and a sliding block fixed at the bottom thereof slide along a sliding groove, and the sliding support rod drives the punching plate to move through a support plate and a piston rod, and the punching plate drives the punch to move together, and is provided with a threaded joint with a distance equal to the punching hole, so that the support plate can be fixed by fixing the locking screw with different threaded joints, so that the locking screw can be operated to accurately adjust the position of the punching plate, thereby increasing the range of the punching operation and being very convenient to use. However, the above device is not provided with an anti-deviation structure. During the process of punching a plastic bag, when the plastic bag contacts the punch, the punch will press the plastic bag downward, causing the two sides of the plastic bag to move toward the middle, thereby causing the position of the punched hole to shift, and at the same time, the hole punched by the punch will have burrs, causing the punch to pull the plastic bag to move together when it moves upward, and the movement of the plastic bag causes the position of the next hole to shift.
