Embodiment Construction

[0011] The present invention will be further described below in conjunction with the drawings.

[0012] Such as figure 1 As shown, the present invention includes a base 1, a positioning plate 3 with positioning holes 2, and a number of tension holders 4 that can maintain the tension of the weft yarn 7. The positioning plates are fixed on both sides of the base. The tension maintaining member is fixedly connected to the middle of the base.

[0013] The positioning plate can be arched, rectangular, or triangular. The positioning hole on the positioning plate can be of any shape, as long as the weft can pass smoothly. There are two positioning plates, located on both sides of the base. The positioning plate can be a large One small can also be the same size.

[0014] The tension maintaining member can be a cylindrical stopper or a rotating shaft that can rotate around its own axis. There is mainly sliding friction between the cylindrical stopper and the weft yarn, and the friction fo...

Abstract

The invention discloses a weaving machine weft yarn tension adjusting device which comprises a base (1), positioning plates (3) and a plurality of tension maintaining parts (4). Each positioning plate (3) is provided with a positioning hole (2), the tension of a weft yarn (7) can be maintained by the tension maintaining parts (4), the positioning plates are fixedly connected on two sides of the base, and the tension maintaining parts are fixedly connected in the middle of the base. The weaving machine weft yarn tension adjusting device has the advantages that pendulosity of the weft yarn is reduced by the aid of the positioning holes in the positioning plates, the uniform and stable tension of the weft yarn is basically maintained by the aid of the tension maintaining parts in the middle of the base, the end breakage rate of the weft yarn is effectively reduced in the weaving process, production efficiency is greatly increased, and product quality is improved.

Description

Technical field [0001] The invention relates to a device for adjusting the tension of a weft yarn, in particular to a weft yarn tensioning device of a loom. Background technique [0002] A yarn perpendicular to the length of the loom, from which the yarn is spun into fabric width threads. All kinds of fabrics have length and width. The length parallel to the edge of the fabric is called the length of the fabric, and the direction of the length of the fabric is the radial direction of the fabric; the length perpendicular to the edge of the fabric is called the width, and the direction of the width is the weft of the fabric. to. When weaving cloth, the yarns used in the radial direction are warp yarns, and the yarns used in the weft direction are called weft yarns. Only the warp yarn has the color of the pattern, while the weft yarn is white or plain. It can also print imitation warp yarn printing effect, but it is easy to distinguish, because the color of the pattern will be on...
