Problems solved by technology

The fixed front shuttle arm is composed of two identical parallel clamping bars and connecting pin shafts. The length of the clamping bar is fixed. When weaving fabrics with different folding diameters, the front shuttle arm must be customized or replaced on site. Time-consuming and labor-intensive and increased spare parts reserves
[0004] In the existing adjustable front shuttle arm (utility model patent: ZL 200720113380.5), the adjustment of the length of the front shuttle arm is realized by adjusting the relative position of the clip frame and the clip frame adjustment seat, which overcomes the problem that the length of the fixed front shuttle arm cannot be adjusted. defect
However, the angle cannot be adjusted, and at the same time it is adjusted manually, and the adjustment accuracy is not high
Therefore, this adjustable front shuttle arm can only reduce the reserve of spare parts, and cannot adapt to the size ring for real-time diameter change.

Embodiment 1

[0021] Such as Figure 1 ~ Figure 3 As shown, a circular loom weft inserter with variable diameter function includes a weft squeezing device 1 at the front end of a shuttle arm and an adjustable shuttle arm mechanism. The weft squeezing device 1, such as figure 2 As shown, the steel ball 11, the ball sleeve 12, and the second spring 13 are included. The steel ball 11 is closely attached to the weft at the weaving mouth, and at the same time, it has rolling friction with the yarn to reduce the damage to the yarn. It is suitable for carbon fiber and glass. Fibers and other brittle materials; the adjustable shuttle arm mechanism includes the left shuttle arm 2, the first compression spring 3, the stopper 4, the middle link 6, the middle link 7; during the weaving process, when the diameter of the cloth opening changes, The front end of the shuttle arm is affected by the tension of the yarn, the length of the left shuttle arm 2 changes, the middle link 7 rotates around point A, and...

Embodiment 2

[0023] Such as Figure 4 ~ Figure 6 As shown, a circular loom weft inserter with variable diameter function includes a weft squeezing device 1 at the front end of a shuttle arm and an adjustable shuttle arm mechanism. The weft squeezing device 1, such as Figure 5 As shown, it includes a deep groove ball bearing 14 and a bearing sleeve 15. The deep groove ball bearing 14 and the bearing sleeve 15 have an interference fit; the deep groove ball bearing is bolted to the left shuttle arm 2 and the right shuttle arm 8 to ensure the bearing sleeve 15 There is rolling friction with the yarn at the weaving mouth, which reduces the damage to the yarn. It is suitable for brittle materials such as carbon fiber and glass fiber; the adjustable shuttle arm mechanism includes the left shuttle arm 2, the compressed first spring 3, The stopper 4, the right curved shuttle arm 9, the third spring 16 and the right shuttle arm extension rod 10. During the weaving process, when the diameter of the c...

Abstract

The invention relates to a circular weaving machine weft insertion device with the reducing function. The circular weaving machine weft insertion device comprises a weft squeezing device arranged at the front end of a shuttle arm, and an adjustable shuttle arm mechanism. By utilizing steel balls or idler wheels, the weft squeezing device is closely attached to weft yarn at the position of a weaving opening. Rolling friction is formed between the weft squeezing device and the yarn, so that damage to the yarn is reduced. The adjustable shuttle arm mechanism can passively adjust the relative positions among rods under the effect of warp tension so as to adapt to real-time reducing of the weaving opening. The weft insertion device enables a circular weaving machine to adapt to real-time reducing of the weaving opening, and adaptively adjusts the length and the angle, so that fabric of different diameters is woven.

Description

Technical field [0001] The invention belongs to the technical field of textile equipment, and particularly relates to a circular loom weft inserter with a diameter-reducing function. Background technique [0002] The products produced by ordinary general-purpose circular looms are cylindrical knitted fabrics with a constant caliber, and the caliber adjustment is achieved by manually adjusting the position of the blade or changing the size ring. Zhai Daqing, Yan Zhongqing, and Zhang Bo proposed to realize on-line reduction products by restructuring the rim frame of the universal circular loom, using color difference to detect the change in the diameter of the blade, correcting the wrong teeth online, and assisting corresponding tension control and anti-skid measures. Production. [0003] At present, the front shuttle arm of the circular loom shuttle has two structures: fixed and adjustable. The fixed front shuttle arm is composed of two identical parallel clamping rods and connect...
