Renewable three-dimensional hollow spinning production line and production method

Abstract

The invention belongs to the field of chemical fiber production devices, and aims at providing a renewable three-dimensional hollow spinning production line and production method. The renewable three-dimensional hollow spinning production line is characterized by comprising a front spinning part and a rear spinning part, wherein the front spinning part comprises a proportioning apparatus and a drying apparatus, wherein the drying apparatus is set as a continuous working state; and the rear spinning part comprises a stretching apparatus, a drying box, a cutoff machine and a packaging machine, wherein the drying box is arranged as multiple layers. A material weight is controlled by virtue of a computer, so that the amount of the material can be increased; the drying apparatus continues to work without stopping, so that the working time can be saved, the working time in the unit time is increased, the working efficiency is increased, and more monofilaments can be produced. The large loadof the subsequent stretching apparatus is cooperated with a great amount of output of the front spinning part as well as the drying process in the drying box, the transportation route of the monofilament in the drying box is increased, so that not only can the drying degree be increased, but also the a great amount of output of the front spinning part can be matched. Compared with the conventionaldevice, the yield is apparently increased.

Description

technical field [0001] The invention relates to the field of chemical fiber production equipment, in particular to a regenerative three-dimensional hollow spinning production line and a production method. Background technique [0002] Three-dimensional hollow spinning is a kind of chemical fiber monofilament. Plastic bottle flakes are mostly used as raw materials for chemical fiber monofilament. The semi-finished monofilament is obtained by melt spinning, and then the semi-finished monofilament is drawn and dried to obtain the finished monofilament. [0003] At present, the Chinese patent with the notification number CN105014903B discloses a monofilament automatic production line, which successively includes a mixer, an extruder, a cooling device, a drafting device, a heat setting device, a winding machine, and a raw material bottle for the monofilament. The sheet passes through these mechanisms in turn, is melted into a liquid state, and then sprayed out into filaments, and...

AI Technical Summary

Problems solved by technology

For example, in the drying step of the extruder, it is usually necessary to dry a batch of bottle flakes before drying the second batch of bottle flakes. During this period, it works intermittently, and it is difficult to achieve mass production in a short period of time.
