Problems solved by technology

[0002] The needle plate of the weft insertion mechanism in the prior art circular loom has a structure such as figure 1 and figure 2 As shown, there is only one needle plate body 1, and several through-type threading holes 11 are arranged on the surface of the needle plate body 1. The tension of weft threads introduced is regulated by the number of holes passed through. The disadvantage is that the operation is inconvenient and the tension It is difficult to control, and during the process of weft thread perforation, the weft thread will rub against the threading hole, which will cause great damage to the strength of the weft thread

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0020] The invention provides a needle plate of a weft insertion mechanism for a circular loom, such as Figure 3-6 As shown, it includes the needle plate body 1, reversing roller 4, tensioner 3 and wire retaining plate 2. set up.

[0021] In one embodiment, the tensioner 3 includes a first column 31, a lower supporting plate 33, an upper pressing plate 32, a compression spring 34, a return spring 36 and a compression knob 35, and the first column 31 passes through the needle plate body 1, the l...

Abstract

The invention provides a weft insertion mechanism faller for circular weaving machines, which comprises a faller body, a reversing roller, a tensioner and a weft-blocking plate, and the weft-blocking plate, the tensioner and the reversing roller are arranged sequentially from the left to the right on the surface of the faller body. Compared with the prior art, the weft insertion mechanism faller for circular weaving machines has the following advantages: a weft sequentially passes through the reversing roller, the tensioner and the weft-blocking plate of the weft insertion mechanism faller disclosed by the invention, the materials of the surfaces for the passage of the weft are all wear-resistant ceramic, and tension for inserting the weft is controlled by manually adjusting the magnitude of the elastic force of the spring of the tensioner; and the weft insertion mechanism faller has the advantages of simplicity and convenience in operation, extremely little injury on weft strength, and ensures the compressive strength of a woven fabric.

Description

technical field [0001] The invention relates to a needle plate of a weft insertion mechanism for a circular loom, belonging to the technical field of weaving machinery. Background technique [0002] The needle plate of the weft insertion mechanism in the prior art circular loom has a structure such as figure 1 and figure 2 As shown, there is only one needle plate body 1, and several through-type threading holes 11 are arranged on the surface of the needle plate body 1. The tension of weft threads introduced is regulated by the number of holes passed through. The disadvantage is that the operation is inconvenient and the tension It is difficult to control, and in the process of weft thread perforation, the weft thread will rub against the threading hole, which will cause great damage to the strength of the weft thread. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a needle plate of a weft inse...
