Anti-winding roller device for drawing machine

Abstract

The utility model relates to the technical field of drawing rollers, in particular to a roller winding prevention device for a drawing machine. The anti-winding device comprises a laser shredding mechanism, a mounting bracket, a sensing assembly and a negative pressure fan; the height of each group of sensing assembly is higher than the height of the highest position of the roller surface of the corresponding drafting roller or lower than the height of the lowest position of the roller surface of the corresponding drafting roller; the laser shredding mechanism is mounted on the drafting frame and the mounting bracket; the laser shredding mechanism and the negative pressure fan are positioned on the same side of the corresponding drafting rollers; the port positions of the negative pressure fans and the contact intersection positions of fibers on the corresponding drafting rollers and the roller surfaces are distributed on the two sides of the central axes of the corresponding drafting rollers; and the working end of the laser shredding mechanism points to the roller surface of the drafting roller corresponding to the extending direction of the port of the negative pressure fan. Through reasonable layout, the opportunity of direct contact between the laser shredding mechanism and fibers is reduced, so that the abrasion degree of the cutting mechanism is greatly reduced, and the service life of the cutting mechanism is prolonged.
