Description

Technical Field

[0001] This utility model relates to the field of packaging bag production technology, and in particular to a high-pressure punching device for packaging bags. Background Technology

[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during production and distribution. They are widely used in daily life and industrial production. In the production of packaging bags, punching is required to make the packaging bags more aesthetically pleasing and practical.

[0003] In existing technologies, high-efficiency punching devices require the packaging bag body to be tightened and clamped during use. However, it is usually inconvenient for existing high-efficiency punching devices to tighten and clamp the packaging bag body during use. This makes it easy for the packaging bag body to shift or loosen when the high-efficiency punching device punches holes in the surface of the packaging bag body, resulting in inaccurate punching of the packaging bag body. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to provide a high-pressure punching device for packaging bags that can punch holes on the surface of the packaging bag and can tension the packaging bag.
