Twisting device for twisting polyamide yarns

Abstract

The invention discloses a twisting device for twisting polyamide yarns. The twisting device includes a machine body, a control mechanism, a servo motor, an overfeed motor, spindle speed motors, spindle mechanisms, yarn guide mechanisms, winding mechanisms and braking mechanisms, wherein the winding mechanisms are connected to the servo motor, photoelectric detectors are arranged on the braking mechanisms, the spindle mechanisms are connected to the spindle speed motors, and spacer boards are arranged between the adjacent spindle mechanisms. According to the twisting device, the winding tensionis controlled by adjusting the positions of guide rollers; by means of the spacer boards, the wear of the yarns between the adjacent spindle mechanisms is effectively blocked and accordingly the product processing quality is improved; through the mutual cooperation between the photoelectric detectors and the braking mechanisms, when yarn heads break or fall off from drums, the braking mechanismsautomatically perform stop brake, thereby saving labor and improving work efficiency; as each group of twisting mechanisms work in parallel, when a certain group of operating mechanisms fails, other operating mechanisms can continue to work without requiring overall shutdown maintenance.

Description

【Technical field】 [0001] The invention relates to the technical field of textile machinery, in particular to the technical field of a twisting device used for twisting nylon filaments. 【Background technique】 [0002] Twisting machine is an important part of textile machinery products, which is related to the development of wool and cotton spinning industry. Twisting is to twist two or more single-ply yarns into strands. In a broad sense, in the spinning process, any yarn (shaft, yarn, thread, silk) is twisted, twisted or axially wound around its axis, so that the yarn is "twisted" or wrapped. For "twisting". Twisting can make fibers or fibers or between monofilaments and monofilaments entangled or entangled without loosening or slipping, and has certain physical and mechanical properties (such as strength, elongation, elasticity, etc.) and appearance characteristics (such as gloss, hairiness, etc.) , feel, etc.). In the traditional twisting machine, there are often multi...

Problems solved by technology

In the traditional twisting machine, there are often multiple sets of twisting equipment on the machine tool, but often a failure of one set of equipment will cause the entire twisting machine to be shut down for maintenance, affecting production efficiency; It is easy to be entangled with each other, resulting in knotting, fluffing, cutting, etc., which will affect the strength and quality of the product, making the thread prone to broken ends; when the twisting machine is working, manual supervision is required at all times. Manual downtime, wasting labor
