Description

A yarn conveying device with adjustable tension

Technical Field

The utility model relates to the technical field of yarn conveying, in particular to a yarn conveying device with adjustable tension.

Background technique

Yarn is a textile product made of various textile fibers and processed into products of a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery, etc. It is divided into short-staple yarn, continuous filament, etc. There are many ways to express the fineness of yarn, such as number, metric count, imperial count, denier, etc. (see count). The twist of yarn is expressed in the number of twists per meter or per inch. Wool yarn and wool thread are generally used to weave wool sweaters, wool trousers, wool vests, scarves, hats and gloves and to weave various spring and autumn clothing items. In addition to keeping warm, they also have decorative effects. During production, the yarn needs to be transported and wound.

In the prior art, a yarn conveying device for a ribbon loom is proposed in publication number: CN 213538256 U. In this case, the yarn is placed between an upper cleaning roller and a lower cleaning roller, and the ribbon loom is started. The ribbon loom continuously drives the yarn forward. While the yarn moves forward, the upper cleaning roller and the lower cleaning roller are driven to rotate. The outer walls of the cleaning rollers are provided with a lint-clearing layer to remove impurities on the yarn. At the same time, the cleaning rollers are easy to disassemble and replace. The first support rod is pulled open to drive the telescopic rod to stretch. The insertion rod is no longer engaged with the insertion block, and the cleaning roller can be removed. The operation is simple and convenient, thereby improving the use effect of the existing yarn conveying device for a ribbon loom.

In actual application, the above cases still have some defects. For example, the tension of the yarn cannot be adjusted according to the actual conveying conditions of the yarn, which causes the yarn to become loose and detach from the conveying roller during conveying and subsequent winding, which easily causes the yarn to become knotted. In addition, the spacing between each group of yarns cannot be adjusted according to the winding requirements of the yarn, resulting in a single conveying condition and poor applicability. Therefore, further improvement is needed.
