[0002] A cloth laying machine, also called a cloth cutting machine, is a common device in the field of garment processing, which replaces manual labor to achieve automatic cloth cutting. A cloth cutting machine is a machine that stacks a roll of seamless fabric layer by layer on a cutting table for cutting. It mainly includes a walking mechanism, a cloth feeding mechanism, a cutting knife device, and an electrical control mechanism, etc. The cloth cutting machine mainly drives the cutting knife to perform the cloth cutting action through a walking motor. The automatic cloth cutting machine needs to sharpen the knife every once in a while. Most of the existing knife sharpening devices on cloth cutting machines are manually operated by workers. The workers press the knife sharpener manually, so that the grinding wheel on the knife sharpener contacts the blade of the cutting knife, and the blade is sharpened during the rotation of the cutting knife. The manual method not only increases the labor intensity of workers, but also cannot achieve standardized and precise operation, resulting in the blade not being sharp enough to affect the cloth cutting effect or excessive wear to affect the service life of the cutting knife.

[0003] In view of the above existing technology, it is necessary to improve the structure of the knife sharpening device of the existing cloth cutting machine.
