[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a trimming device for non-woven fabric production which is convenient for position adjustment. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, colorful, low-priced, and recyclable. In the process of cutting non-woven fabric raw materials, a trimming device is needed.

[0003] The cutting position of the existing trimming device is relatively constant, which makes it inconvenient to adjust the cutting position of the non-woven fabric, reducing the trimming efficiency of the device, and making it inconvenient to flatten the non-woven fabric, which easily causes the non-woven fabric to shift, affecting the cutting quality of the non-woven fabric and reducing the practicability of the device.
