Composite shuttle for loom and production thereof

Abstract

A composite shuttle for a loom and its manufacturing process. The composite shuttle consists of a shuttle blank body and a composite plate embedded in a pre-processed groove on the side of the shuttle blank body by bonding. That is, the composite shuttle is produced by the cold inlay bonding process. The characteristics of this new process are: normal temperature, inlaying, and bonding—the phenolic resin laminated cloth board or ultra-high molecular polyethylene and other high-wear-resistant plates, through the adhesive, Adhesive, glued to the surface of the shuttle at room temperature. The advantages of the present invention are: there is no need to pre-process the side of the shuttle blank, since the entire production process does not require a press and a large number of molds, so the investment is very small, and the production and processing are carried out under normal temperature and pressure, without heating and pressing, and without Machine processing, so there is no energy consumption, the labor intensity of workers is low, and the production efficiency is high; most importantly, because it is processed at room temperature, it has no effect on the original excellent toughness of the shuttle body. Static and long life.

Description

technical field [0001] The invention relates to a loom accessory of textile equipment, in particular to a composite shuttle for a loom and a manufacturing process thereof. Background technique [0002] The shuttle is an important accessory of the shuttle loom and plays an important role in sending weft. Due to the shortage of wood, people use plastic instead of wood to produce plastic shuttles, and the development is very fast. For further improving the wear resistance and antistatic properties of plastic shuttles, people have developed composite plastic shuttles again. At present, the production of this kind of composite plastic shuttle adopts the traditional heat-coating process, that is, the surface of the plastic shuttle is heat-coated with phenolic resin cloth through high temperature (160-180°C) and high pressure (3MPA) to improve the wear resistance. and antistatic properties. This heat-covering production process has low efficiency, high energy consumption, and la...

AI Technical Summary

Problems solved by technology

[0008] 6. During heat-covering, once heat-covering quality problems occur, for example, local sol is uneven, etc., the entire shuttle will be scrapped

[0010] 1. Due to the use of hydraulic presses and molds for production and processing, the investment is relatively large;

[0011] 2. Since high temperature and high pressure are used during production and processing, and the duration is long, the energy consumption is high;

[0012] 3. The whole process includes installation, temperature rise, pressure maintenance, cooling, disassembly, etc. There are many steps and long time, so the production efficiency is low;

[0013] 4. Due to the high temperature and high pressure processing, the product deformation is large;

[0014] 5. Since there is no reworkability and the process requirements are high, the production rate is low;

[0015] 6. The most important thing is that under the action of high temperature and high pressure, the original excellent toughness of the shuttle blank is seriously lost, and the shuttle is easily brittle
