Production device and technological method of twisted yarn for ground retreating

Abstract

The invention relates to the technical field of plied yarn processes, in particular to a production device and process method of plied yarn for ground retreating. The production process method of the plied yarn for external retreating on the ground comprises the following steps: rotating a raw yarn cake to a creel, firstly passing through a probe yarn guide eye on the creel, then passing through a yarn guide bar on a suspension yarn regulator, continuously passing through a stand column yarn guide eye, then passing through a yarn guide eye beam splitting wheel on the ground, and finally passing through a yarn guide eye of a winder and a V-shaped guide wheel in the horizontal direction to enter the winder; plied yarns are obtained; and the yarn enters the winder at an angle of 42 degrees through the V-shaped guide wheel. According to the production process method for the ground twisted yarn for external retreating, the use efficiency of the twisted yarn product for external retreating is improved, and the quality requirement of customers for the product is guaranteed. The invention also provides a production device.

Description

technical field [0001] The invention relates to the technical field of plied yarns, in particular to a production device and a process method for plied yarns for ground receding. Background technique [0002] Ply yarn is a thread formed by twisting two or more single yarns. Its strength and wear resistance are better than single yarn. At the same time, the ply yarn can also be combined and twisted in a certain way to obtain a double twisted ply yarn. The existing ply yarn for retreating is to produce a ply yarn from the ply yarn, that is, a double twisted ply yarn. In the current glass fiber roving winding process, two methods are used to rewind the raw silk cake: one is to start from the inner layer of the raw silk cake and carry out the raw silk rewinding from the inside to the outside, this method is called It is the internal retreat process, and the other method is to carry out the original silk rewinding from the outside to the inside from the outer layer of the raw s...

Problems solved by technology

When adopting the external retreating process, the original yarn cake is used on the flat creel and the yarn car, which is suitable for engineering plastic yarn, twisted ply yarn, etc. This retreating method causes the monofilament to be damaged due to the different angles of the yarn cake during production Inconsistent tension will affect the yarn banding and drape, seriously affecting the smooth use of products and the quality of downstream products

[0003] The existing ply yarn production process for retreating is specifically the above-ground winding production process, that is, the ply yarn raw silk is wound on the creel, and the yarn is horizontally guided to the winder through the hanging yarn adjuster, idler rollers, and U-shaped guide wheels. The upper part is then bent downwards to enter the winding, and the inner sleeve of the paper tube is wound. The winding ratio is only 2.43. The bending angle of the yarn when entering the winding machine is as high as 90°, which greatly damages the bending and tension of the yarn.

Moreover, the products produced by this process often have problems such as wool, broken yarn, and knotted wool yarn during use, resulting in yarn breakage and production stoppage, and broken yarn joints cause the strength of the pultrusion materials to decrease and cause customer complaints And other issues
