AI Technical Summary

Technical Problem

The cutting device for the existing non-woven fabric production is difficult to effectively adjust non-woven fabrics of different widths and thicknesses, resulting in tilting during transmission and uneven cutting positions.

Method used

A cutting device including a bracket, a protective frame, a cutting blade, a limit groove, a bidirectional threaded rod and a stop is designed. The width and thickness of the non-woven fabric can be adjusted through the sliding groove, a bidirectional threaded rod and a limiting assembly to ensure the limit and smoothness of the transmission time.

Benefits of technology

It effectively avoids the inclination of the non-woven fabric during the transport process, ensures the flatness of the cutting position, and supports adaptive transmission and cutting of non-woven fabrics of different thicknesses.

Abstract

The utility model discloses a cutting device for non-woven fabric production, which belongs to the technical field of non-woven fabric production and comprises a support, the top of the support is connected with a protective frame, and the bottom of the protective frame is provided with a cutting blade capable of moving up and down. The non-woven fabric conveying device has the beneficial effects that by arranging the sliding grooves, the two-way threaded rods, the sliding plates, the check blocks and the like, when non-woven fabrics with different widths are placed, the rotating non-woven fabrics are conveniently limited, and the situation that when the non-woven fabrics are rotationally taken out, carrier rollers for the non-woven fabrics move in limiting grooves in the two sides of a supporting frame, the conveyed non-woven fabrics are inclined, and the non-woven fabrics are damaged is avoided. By arranging a limiting rod, a guide wheel and a first guide roller, non-woven fabrics with different widths can be conveniently limited during transmission, and by arranging a top plate, a screw rod and a screw cylinder, the distance between a roller on a rotating shaft and a second guide roller can be adjusted, and non-woven fabrics with different thicknesses can be adjusted during transmission.
