[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc., are made of polyester fiber and polyester fiber. They are made through a needle-punching process and can be made into different thicknesses, feels, hardness, etc. Non-woven fabrics are moisture-proof, breathable, flexible, thin, flame-retardant, non-toxic and tasteless, low-priced, and recyclable. They can be used in different industries, such as sound insulation, heat insulation, electric heaters, masks, clothing, medical, filling materials, etc. The corner cutting device used in the processing and production of non-woven fabrics is a device used to remove the corners of non-woven fabric rolls. In the production process of non-woven fabrics, the corners of the rolls are usually irregular or redundant parts that need to be cut off to obtain neat product edges. Using the corner cutting device, non-woven fabric manufacturers can effectively handle the corners of the rolls, improve product quality and production efficiency, and reduce waste and labor costs.

[0003] In actual use, the existing corner cutting device for non-woven fabric processing and production is not convenient for synchronously rotating the two sets of winding shafts, and it is difficult to ensure that the winding tension and density on the winding shafts are consistent.
