Sixteen-color weft selecting device

Abstract

The invention provides a sixteen-color weft selecting device. The device comprises two rows of weft selecting needles arranged in parallel, the weft selecting needles are installed in a sector-shapedshell, and the number of the weft selecting needles in each row is eight; the device is characterized in that each weft selecting needle comprises a needle head, a guide rod, an inertia impact bar anda needle tail; the needle head, the guide rod, the inertia impact bar and the needle tail are connected through a boss, the guide rod is of a hollow structure and is internally provided with a compressed spring, and force is applied to the contact surface of the inertia impact bar, so that the compressed spring abuts against and is meshed with one end of the inertia impact bar; the inner diameterof the guide rod is larger than the outer diameter of the inertia impact bar, and the length of the guide rod is greater than the length of the inertia impact bar. Accordingly, the problem that whenthe weft is changed, the movement and inertia of a color selection mechanism are large is solved, and meanwhile the problem that, when electromagnetism is used for driving weft yarn to move, an electromagnetic coil is likely to be damaged is solved; therefore, the working efficiency of a loom is improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a sixteen-color weft selection device. Background technique [0002] At present, the weft yarn selection of the loom generally adopts a weft selection device of 8 colors or less, which is used to weave decorative fabrics such as curtains and wall coverings. [0003] Fabric, there are the following problems: the weft selection device with less than 8 colors can weave fabrics with relatively monotonous color and luster, and weave high-grade jacquard fabrics [0004] , the weft selection device is not sufficient. In order to enrich the patterns manufactured by the loom and the application range of the loom, and to obtain a loom with rich patterns and suitable for high-grade fabrics, the weft selection device is improved. One of the methods is to increase the number of weft selection needles, but after increasing the number of weft selection needles, the action and inertia of the c...

Problems solved by technology

[0005] Technical problem to be solved: the purpose of this invention is to provide a sixteen-color weft selection device, which overcomes the problem of large action and inertia of the color selection mechanism when changing wefts, and at the same time overcomes the easy damage of the electromagnetic coil when using electromagnetics to drive the weft yarn movement problems, thereby improving the efficiency of the loom and reducing production costs
