Description

TECHNICAL FIELD

[0001] The present application belongs to the field of fabric cutting machines, in particular to a garment fabric edge-finding cutting machine. BACKGROUND

[0002] The existing garment fabric edge-finding cutting machine needs to place the fabric on the cutting table before cutting. Most cutting machines use manual placement of fabric or use a fabric pulling structure to pull and place the fabric, but do not perform subsequent flattening work on the fabric. This can easily cause local wrinkles to occur after the fabric is placed, and the existence of such wrinkles can directly affect the accuracy of edge-finding cutting, causing cutting size deviation, uneven edges, and other problems, thereby affecting the quality of finished products. The generation of wrinkles is mainly due to the softness and elasticity of the fabric itself, and uneven stress or improper operation during handling and laying can easily cause deformation.

[0003] To address this issue, conventional practices include manually flattening the fabric, increasing fabric tensioning devices, or using auxiliary tools to flatten the fabric before cutting. However, manual flattening is inefficient and difficult to ensure consistency, tensioning devices have poor adaptability to different fabric materials, and auxiliary flattening tools may cause indentations or damage to some delicate fabrics. Therefore, existing solutions have certain limitations in terms of operation efficiency, adaptability, and fabric protection, and there is an urgent need for more efficient and widely applicable surface flattening technology or structural design to improve cutting accuracy and production efficiency. Therefore, we hope to design a garment fabric edge-finding cutting machine with a new structure to solve this problem. SUMMARY
