[0002] Fabric hair surface repair refers to the repair of the fabric surface through specific processes and technologies to restore its original appearance and performance. This repair process usually involves sanding the fabric surface to improve its feel and appearance. Sanding finishing is a post-processing process. Through the friction between the sanding machine and the emery leather, a layer of short fluff is formed on the fabric surface, thereby increasing the warmth and softness of the fabric. The sanding process uses sharp abrasives (such as emery grains or metal abrasives) to rub the fabric surface to form fluff in the fibers, making the fabric surface softer and more comfortable. Traditional hair surface repair mostly involves manual feeding, which is inefficient. In order to improve this situation, a feeding mechanism for a hair surface repair machine is proposed.

[0004] Although the arrangement of the pipe rack consisting of six equidistantly arranged cylinders is realized, it is beneficial for the fixed installation and positioning of the pipes; the arrangement of the driving components as two groups symmetrically arranged on the upper and lower sides of the fixed rack is beneficial for repairing the upper and lower sides of the pipes at the same time, thereby increasing the repair efficiency;

[0005] However, the problem that the existing feeding mechanism is not conducive to convenient elastic extrusion and feeding of cloth during use, is not conducive to centering and straightening the cloth for feeding, and affects the flatness of the cloth feeding. Utility Model Content
