Synthetic fiber rotary spinning system and spinning method

Abstract

The invention relates to the technical field of textile, and provides a synthetic fiber rotary spinning system which comprises a shell, a mounting frame is fixedly connected to the outer wall of the shell, a gear is rotatably connected to the inner wall of the mounting frame, a spraying assembly is fixedly connected to the bottom of the gear, and a maintaining assembly is connected to the outer wall of the gear in a meshed mode. The bottom of the maintaining assembly is movably connected with a speed reduction assembly. According to the synthetic fiber rotary spinning system and spinning method, the transmission teeth are in meshed connection with the gear, the rotation linear speed of the transmission teeth is the same as that of the gear, and the distance between the transmission teeth and the circle center of the gear is lengthened, so that the angular speed of the gear is slowed down; the rotating speed of the motor cannot be reduced immediately, so that the meshing position of the transmission teeth and the gear is changed, the rotating speed of the screw is reduced, and the spinning stability can be maintained due to the fact that the meshing position of the transmission teeth and the gear is variable and the angular speed is kept unchanged.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a synthetic fiber rotary spinning system and spinning method. Background technique [0002] Spinning is to heat and melt the fiber-forming polymer slices in a screw extruder to form a melt, and then the melt is quantitatively, continuously and uniformly extruded from the pores of the spinneret. The spinning efficiency of the spinning equipment is high, and the spinning The silk quality is good, and the structure and performance of the fiber are perfected and improved. [0003] In the prior art, the extruding speed of the screw rotation directly affects the speed of the melt ejection, and the stall of the screw will cause the fiber polymer chips to be unable to melt completely, and the incompletely melted fiber polymer blocks the nozzle and cannot be spun , and the ejection speed is too fast, and the spinning quality has problems. [0004] Therefore, the demand for high-reliabi...

Problems solved by technology

[0003] In the prior art, the extruding speed of the screw rotation directly affects the speed of the melt ejection, and the stall of the screw will cause the fiber polymer chips to be unable to melt completely, and the incompletely melted fiber polymer blocks the nozzle and cannot be spun , and the ejection speed is too fast, the spinning quality has problems

[0004] Therefore, the demand for high-reliability products is imminent, so we proposed a synthetic fiber rotary spinning system and spinning method, which has the functions of preventing the fiber polymer from being completely melted and blocking the spinning and controlling the spinning speed to prevent spinning. Quality suffers
