Description

Technical Field

[0002] Punching is a processing technique widely used in materials such as leather and fabric. It applies a concentrated load to the material, separating it along a specific contour. In leather and fabric processing, punching technology enables precise and efficient cutting to meet diverse production needs.

[0003] During the die-cutting process for materials like leather and fabric, length measurement is a critical step in ensuring the die-cut products meet specification requirements. Leather products such as clothing, luggage, chairs, and footwear have strict dimensional accuracy requirements. Inaccurate die-cut dimensions directly affect the product's appearance, function, and durability. Furthermore, controlling die-cut dimensions through length measurement maximizes raw material utilization and minimizes waste.

[0004] In actual production, leather and cloth may appear in rolls for easy storage and transportation. However, during the punching process, they are usually directly unfolded and laid flat on the workbench of the punching machine. The length of the material is then measured with a ruler or other reference objects before punching, which makes length measurement inefficient.

[0005] For this purpose, a punching encoder length measuring device is proposed. Utility Model Content
