Coating sheet yarn winder

Abstract

The invention relates to a coating sheet yarn winder, which is characterized in that: the winder is provided with a disc-head active unwinding mechanism (1), a device for controlling the synchronous operation of an unwinding motor (32) and a winding motor (18), and a yarn dividing device (6). The yarn dividing device (6) separates coating sheet yarns (3) into a plurality of layers of coating single yarns (7) which do not adhere to each other and remain a certain distance; and the coating single yarns (7) are led into yarn guiding porcelain plates (23) of the corresponding layers on a winding component (9) after passing through a tension adjusting gear (8), and enter a single yarn winding mechanism (22) after being guided to a tensioner (21) in one-to-one correspondence. The coating sheet yarn winding machine adopts a multi-layer multi-gear structure and a same-direction same-side yarn-guiding arrangement manner to achieve around 400 spindles in each winding, has the characteristics oflarge bobbin amount, small occupied space, convenient yarn guiding and bobbin replacement operations, high yield, low cost, capacity of satisfying the needs of coating cheese industrialization for high-count high-speed knitting, and the like, and opens up new ways for weaving novel fabrics which are energy-saving, emission-reducing, environmentally-friendly and good for health.

Description

Technical field: [0001] The invention belongs to the field of textiles, in particular to a kind of coating sheet yarn which is wound on the pan head after the raw yarn warped on the warp beam is circularly dyed with paint, and is directly collectively unwound to form a package yarn winder. Background technique: [0002] Paint dyeing is different from the traditional dyeing process of reactive dyes and oxidation dyes. Paint dyeing has the characteristics of energy saving, emission reduction, environmental protection, health, and wide color spectrum. Low, in the past, in order to obtain dope cheese, people used methods such as skein dyeing, loose cheese dyeing and color spinning that were easy to wind into cheese, all of which were caused by color difference, large color difference, low color fastness and lack of paint style, etc. unavailable for some reason. [0003] In recent years, people have solved the problem of yarn paint dyeing by adopting a new process of paint ring...

Problems solved by technology

[0002] Paint dyeing is different from the traditional dyeing process of reactive dyes and oxidation dyes. Paint dyeing has the characteristics of energy saving, emission reduction, environmental protection, health, and wide color spectrum. Low, in the past, in order to obtain dope cheese, people used methods such as skein dyeing, loose cheese dyeing and color spinning that were easy to wind into cheese, all of which were caused by color difference, large color difference, low color fastness and lack of paint style, etc. unavailable for reason

[0003] In recent years, people have solved the problem of yarn paint dyeing by adopting a new process of paint ring pad dyeing, but the dyed yarn is in the form of flakes and is wound on the pan head, and the number of heads is as high as several hundred or more. It is technically difficult to wind such a piece of yarn into a bobbin, because in the process of winding the piece of yarn, firstly, the surface of the piece of yarn on the pan head is not smooth, resulting in looseness of the single yarn after unwinding; The reason is that the unwinding diameter of the pan-head yarn and the diameter of the winding yarn are always changing. If they are not coordinated, the phenomenon of yarn collapse and wave yarn will be caused; the third is due to the low strength of the yarn, especially the high-count yarn; the fourth is that at the same time There are so many windings, if the instantaneous winding speed of each winding mechanism is inconsistent, it will also cause broken ends and yarn waves; fifth, the problems of untwisting and twisting of the yarn during the winding process directly affect the high-speed continuous winding. cylinder

At present, the existing winding machine series disclosed in the society all belong to single yarn winding, and there are also indigo warp yarn winding machines. Sub-sections up to about 40 heads and then winding methods cannot meet the industrialization needs of high-count and high-speed winding of coated yarns
