Spinning process equipment for polyester production

Abstract

The invention discloses spinning process equipment for polyester production. The spinning process equipment comprises a grading box, a melting furnace, a spinneret device, a condensing box and a bidirectional winding device. The grading box comprises a pulverizing cover and a filtering box. The pulverizing cover is fixedly arranged at the head of the filtering box, and is hermetically connected with the filtering box. The spinning process equipment has the advantages that the structure of conventional spinning equipment for polyester production is improved to solve the problems of non-thorough melting and inconvenience in separation between spinneret plates and silks after spinning due to insufficiently disperse feeding and no cutting and screening structure of existing polyester production equipment, and the problem that winding structures do not have bidirectional winding functions; through the bidirectional winding device, users can conveniently and timely wind the spun silks; a motor is used for winding the silks in both forward and backward directions, so that intertwining during winding is effectively avoided, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of polyester production equipment, in particular to spinning process equipment for polyester production. Background technique [0002] At present, polyester filament production equipment includes slice conveying, drying, spinning, winding, stretching twisting, deformation, stretching deformation, stretching warping, spinning stretching and winding one-step method, micro-denier filament, industrial yarn , network yarn and air textured yarn, the main process flow: first spinning melt preparation, continuous polymerization worthy of the melt award, after pre-crystallization and drying, the fiber-forming high polymer slices are added from the polymer hopper, and heated in sections according to requirements The advanced screw extruder successively performs melting, mixing, metering and extrusion, and the elbow between the spinning boxes is sent to the melt metering pump through the extrusion machine, and then the...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of spinning process equipment for polyester production, aiming to improve the existing polyester production equipment, which has insufficient dispersion of feeding materials, does not have a segmentation and screening structure, and is likely to cause insufficient melting and spinnerets after spinning. It is easy to separate from the wire, and the winding structure does not have the problem of simultaneous two-way winding function
