Description

Technical Field

[0001] The utility model relates to the technical field of cloth processing, in particular to a positioning mechanism of a cloth punching machine. Background Art

[0002] In many applications, fabrics need to be punched for fixing or decoration. Fabric punching machines are usually able to adapt to fabrics of different materials, thicknesses and sizes, and can be adjusted as needed to meet different punching needs.

[0003] Fixing the fabric is the basis for ensuring the accuracy of punching. The fabric needs to maintain a stable position during the punching process. If the fabric moves or slips during punching, it will cause inaccurate punching positions or even damage the fabric. Traditional methods mostly use a single pressing mechanism to press the fabric, which is unable to flatten and tension the fabric, causing the fabric to easily overlap and wrinkle, affecting the accuracy of punching.
