Description

Technical Field

[0001] The utility model relates to the technical field of edge trimming devices, in particular to an edge trimming device for nonwoven fabrics. Background Art

[0002] Non-woven fabric, also known as non-woven fabric, is made of directional or random fibers. It is called cloth because it has the appearance and certain properties of cloth. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, low price, and recyclable. For example, it mostly uses polypropylene (pp material) pellets as raw materials and is produced by a continuous one-step process of high-temperature melting, spinning, laying, and hot pressing and winding.

[0003] Non-woven fabrics are continuous strips after leaving the factory. Due to the processing technology, the head end of the non-woven fabric is uneven and has burrs, and needs to be cut with a trimming device. The existing trimming device often only uses a cutter for cutting. When cutting, there is often a lack of a clamping mechanism to press the non-woven fabric. As a result, the non-woven fabric is easy to slide when the cutter cuts, resulting in cutting failure or cutting errors, and the cutting quality cannot be guaranteed. Utility Model Content
