Plastic-covered silk thread production line

Abstract

The invention discloses a plastic-covered silk thread production line. The plastic-covered silk thread production line comprises a yarn frame, thread guide frames, an extrusion unit, a diameter measurement instrument, a circular cooling water groove, a dryer, a traction machine, a take-up unit and a control cabinet; at least two rolls of silk threads to be covered are wound on the yarn frame, theextrusion unit is arranged on the rear side of the yarn frame in a spaced manner, when the silk threads penetrate through an extrusion film of an extruder, the plastic-covered silk thread is formed, the circular cooling water groove is arranged on the rear side of the extrusion unit in a spaced manner, a curing plastic layer of the plastic-covered silk thread is cooled, the dryer is arranged on the rear side of the circular cooling water groove in a spaced manner, and the dryer dries the plastic-covered silk thread; the traction machine is arranged on the rear side of the dryer in a spaced manner, and therefore, the plastic-covered silk thread is conveniently and backwards pulled out; the take-up unit is arranged on the rear side of the traction machine in a spaced manner, and is used forwinding finished product plastic-covered silk thread, the two thread guide frames are included, and the diameter measurement instrument is arranged on the rear side of the extrusion unit in a spaced manner, and is used for measuring the outer diameter of the plastic-covered silk thread. The production efficiency is greatly improved, the silk thread quality is effectively ensured, the production thread changing frequency is reduced, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of yarn manufacturing, in particular to a production line for plastic-coated silk yarns. Background technique [0002] Plastic-coated wire with a skin-core structure. These types of wires are made of a layer of plastic coated on the surface of the yarn. Because of the characteristics of the surface-coated plastic material, different effects can be achieved. In recent years, it has grown from industrial use to From household use to wearable use, its uses are becoming more and more extensive, and the market demand is increasing. [0003] For the manufacture of plastic-coated wire, at present, all manufacturers use the same equipment and processes as cable production, and then use textile equipment for oiling, rewinding, and splitting, etc. Due to the different characteristics of cables and wires, There are congenital defects in the production of wires with cable equipment, which leads to: 1. The production capacity is ...

AI Technical Summary

Problems solved by technology

[0003] For the manufacture of plastic-coated wire, at present, all manufacturers use the same equipment and processes as cable production, and then use textile equipment for oiling, rewinding, and splitting, etc. Due to the different characteristics of cables and wires, There are congenital defects in the production of wires with cable equipment, which leads to: 1. The production capacity is very low, and the production of cables is a single extrusion. Since the wires are very thin, they are generally below 600D or 0.3mm in diameter. Although the extrusion speed is greatly improved, a production line can extrude more than 1 million meters a day, and can only produce dozens of kilograms

2. Quality control is difficult. Generally speaking, the cross-loading surface of the cable is relatively large, and the wire diameter of the wire is very small, which is smaller than the tolerance value of the wire diameter of ordinary cables; It is easy to break, and the tension of the silk thread is relatively small, so it is easy to stretch and break; these problems make it difficult to guarantee the quality of the silk produced by the existing cable equipment

3. The process route is extended. Since the cable equipment is mainly designed for cable manufacturing, the finished products cannot be directly used in textile machinery. It needs subsequent reprocessing such as oiling, glazing, rewinding, and spindle division. use

4. The cost is high. Due to the small equipment capacity and low efficiency, the processing cost is very high, which affects the promotion and use of products
