[0002] Non-woven fabrics are also called non-woven fabrics, needle-punched cotton, needle-punched non-woven fabrics, etc. They are made of polyester fiber and polyester fiber (referred to as PET) and are made through a needle-punching process. They 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. In the process of producing, processing and rolling non-woven fabrics, it is usually necessary to trim the non-woven fabrics to make the edges of the non-woven fabrics smoother. Therefore, we proposed a non-woven fabric trimming machine.

[0003] According to the existing patent publication number: CN218538715U, a winding and trimming machine for non-woven fabric production includes an operating table, a fixed support column, a winding roller, a fixed positioning block, a movable adjustable trimming mechanism, a fixed guide rod, and a first connected limit plate. The non-woven fabric is pressed by a fixed adjustable pressing mechanism, the non-woven fabric is cut by a movable adjustable trimming mechanism, and the non-woven fabric is rolled up by a winding roller. However, the cutting blade can only move up and down but not left and right, and the length of the winding roller cannot be adjusted, so non-woven fabrics of different widths cannot be rolled up and cut. For this reason, we propose a non-woven fabric trimming machine. Utility Model Content
