Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing, and specifically relates to a device for cutting non-woven fabric to a fixed length in non-woven fabric production. Background Technique

[0002] Spunlace non-woven fabric is a fabric obtained by spraying high-pressure micro water jets onto one or more fiber webs, so that the fibers are entangled with each other, thereby strengthening the fiber web to have a certain strength. When producing non-woven fabric, it is necessary to cut it to a fixed length.

[0003] The Chinese patent discloses a non-woven fabric cutting device with a cleaning function, with the publication number CN215542915U, which includes a base. A cloth winding roller is arranged on the left side of the base, and non-woven fabric is wound around the cloth winding roller. A conveyor belt is arranged on the right side of the cloth winding roller. A processing table is arranged on the right side of the base. The processing table and the conveyor belt are on the same horizontal plane. A filter plate is arranged on the top of the left part of the processing table. A fixing frame is arranged on the filter plate, and a cleaning mechanism is arranged inside the fixing frame. A cantilever is arranged on the right side of the processing table, a hydraulic pusher is arranged on the left side of the cantilever, and a cutting knife is arranged on the hydraulic pusher; the device is convenient for cleaning the non-woven fabric during cutting, and has high practicability.

[0004] However, it still has the following disadvantages: The device uses a hydraulic pusher to control the cutting knife to cut the non-woven fabric downward. However, when the device cuts the non-woven fabric, it does not press the non-woven fabric, which may cause the non-woven fabric to shift during cutting. For this reason, we have proposed a device for cutting non-woven fabric to a fixed length in non-woven fabric production to solve this problem. Content of the Utility Model
