Problems solved by technology

[0003] Most of the current spinning devices adopt the structure of side feeding and top surface pressing. When the pressing plate completely extrudes the molten amount and moves to the bottom, it needs to rise to the top of the feeding port again before the next feeding can be carried out, so that the processing process In the process, there will be a waiting time for the pressure plate to reset, which makes the whole spinning process longer and less efficient; during processing, only spinning with a fixed diameter can be processed, and the spinneret cannot be quickly switched

Embodiment Construction

[0030] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the present invention will be further explained below in conjunction with specific embodiments.

[0031] Such as Figure 1-Figure 5 As shown, a regenerated polyester fiber spinning process of the present invention includes the following steps:

[0032] S1, put the scraps into the cleaning equipment for cleaning; then dry;

[0033] S2: Put the leftover material dried in S1 into the spinning device for spinning;

[0034] S3, cooling the filaments in S2, and then winding them on a reel;

[0035] The spinning device used in this method includes an upper box body 1, a lower box body 2, a feeding mechanism 3, an extrusion mechanism 4, a switching mechanism 5, a driving mechanism 6, a distribution plate 7, a spinning mechanism 8, a supporting mechanism 9, The second filter plate 9a and the discharge box 9b; the bottom surface of the upper box body 1 is pr...

Abstract

The invention relates to the technical field of spinning, in particular to a regenerated polyester fiber spinning process. The process includes the following steps of S1, putting leftover materials ina cleaning device to be cleaned, and then drying the leftover materials; S2, putting the leftover materials dried in the step S1 in a spinning device for spinning fiber; S3, cooling the fiber in thestep S2, and then winding the fiber on a roller. Through the spinning device adopted in the method, when a pressing plate completely extrudes the materials to rise, a first filter plate can be conveniently switched to be placed on the top of a discharge port, discharging can be conveniently realized when the pressing plate upwards returns, the area between the pressing plate and a second filter plate can be filled with the raw materials when the pressing plate moves to the top end, and the pressing plate can be driven again to move down for the next time of processing.

Description

Technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning process of regenerated polyester fiber. Background technique [0002] The raw materials of recycled polyester fiber are waste polyester bottle flakes and waste polyester textile scraps. The current recycled polyester fiber spinning device is mainly composed of component head cover, pressure plate, distribution plate and spinneret. The extrusion can realize spinning production. [0003] Most of the current spinning devices adopt the structure of side feeding and top surface pressing. When the pressing plate completely extrudes the melted amount and moves to the bottom end, it needs to rise to the top of the feeding port again to perform the next feeding, which makes the processing process In the process, there will be a waiting time for the pressure plate to reset, which makes the entire spinning process time longer and lower efficiency; during processing, only spinning with...
