Description

Technical Field

[0001] The invention belongs to the field of textile equipment, and in particular relates to a three-dimensional braiding tightening device. Background Art

[0002] At present, weaving mainly includes two-dimensional weaving and three-dimensional weaving. In two-dimensional weaving, the fabric mainly relies on adjusting the weaving angle to control the final fiber volume content. In three-dimensional weaving, in addition to relying on the weaving angle to control the fiber volume content of the fabric, manual assistance is also required to achieve the weaving of fabrics with a larger fiber volume content. After manual assistance, the weaving angle needs to be measured in real time, resulting in discontinuous production, inconsistent fabric tightness, and other phenomena, which ultimately results in uneven quality of fabric preforms, making it difficult to achieve large-scale, continuous production.

[0003] Based on this, two-dimensional weaving usually sets a weft beater to compact the weft. With the development of three-dimensional textiles, the textile threads of three-dimensional textiles also need machines similar to weft beaters to compact the woven layer. Since three-dimensional textiles often have a multi-layer textile thread structure, the weaving process is much more complicated than the two-dimensional textile process. Therefore, the design requirements for the tightening device used in the three-dimensional weaving process are more stringent. The tightening device not only needs to be able to compact the woven layer to make the fabric uniform in tightness, but also needs to realize the automated operation of the tightening process.

[0004] In view of this, the present invention is proposed. Summary of the invention

The rotating protrusion 212 is rotatably provided on the supporting seat 22, and the supporting seat 22 is provided on the vertical moving mechanism 3.

[0050] In the embodiment of the present invention, a wire-beating rod 1 is provided on the rotating seat 21. Figure 1 The state of the tie rod 1 at different rotation angles is shown in the figure. The rotating seat 21 may be provided with a plurality of plug holes 211, and the plurality of plug holes 211 are distributed at different positions of the rotating seat 21. The end of the tie rod 1 is selectively plugged into one of the plug holes 211 to adjust the position of the tie rod 1 on the rotating seat 21 to adapt to the tie rods at different positions.

[0051] The rotation of the threading rod 1 is realized by rotating the rotating protrusion 212 on the support seat 22. The support seat 22 is arranged on the vertical moving mechanism 3, and the vertical moving mechanism 3 drives the support seat 22 to move up and down, so that the threading rod 1 can move up and down.

[0052] Specifically, the bottom of the support seat 22 is provided with a first limiting groove 221 with a notch facing downward, and the front and rear sides of the first limiting groove 221 are respectively provided with openings, and the rotating protrusion 212 is inserted into the first limiting groove 221 through the front opening of the first limiting groove 221, and the rotating protrusion 212 turns upside down in the first limiting groove 221. The front opening of the first limiting groove 221 enables the rotating protrusion 212 to turn upside down in the first limiting groove 221;

[0053] A first through hole 213 is provided on the rotating protrusion 212, and two limiting protrusions 2211 protruding downward are provided at the bottom of the support seat 22. The two limiting protrusions 2211 and the bottom of the support seat 22 form a first limiting groove 221, and each limiting protrusion 2211 is provided with a second through hole 2212. The first through hole 213 overlaps with the two second through holes 2212, and a rotating shaft 23 for the rotating protrusion 212 to rotate is passed through the first through hole 213 and the two second through holes 2212.

[0054] The first through hole 213 overlaps with the two second through holes 2212, so that the rotating protrusion 212 can rotate smoothly on the rotating shaft 23, thereby ensuring the stability of the rotating protrusion 212; the setting of the two limiting protrusions 2211 can provide limiting support for the rotating protrusion 212, thereby improving the stability of the rotating protrusion 212 during rotation.

[0055] The first through hole 213 and the second through hole 2212 are circular holes, and the rotating shaft 23 is cylindrical, so as to improve the assembly strength of the first through hole 213, the second through hole 2212 and the rotating shaft 23.

[0056] The rotating protrusion 212 includes an upper side wall, a lower side wall, a left side wall and a right side wall. The upper side wall and the lower side wall extend horizontally front to back. The left side wall is in contact with the rear side of the rotating seat 21, and the right side wall is inclined from top to bottom toward the rear side of the rotating seat 21, so that the extension length of the upper side wall is greater than the extension length of the lower side wall.

[0057] Furthermore, a recessed portion recessed upward is provided at the bottom of the support seat 22, and the recessed portion and the two limiting protrusions 2211 form a first limiting groove 221, and the opening on the front side of the first limiting groove 221 includes an upper section and a lower section, the upper section gradually extends obliquely outward from the first limiting groove 221 from top to bottom, and the lower section extends vertically from top to bottom, and the opening on the rear side of the second limiting groove 413 gradually extends obliquely inward from top to bottom into the first limiting groove 221, so that the front side wall of the limiting protrusion 221 includes an upper limit section and a lower limit section, the upper limit section gradually extends obliquely outward from the first limiting groove 221 from top to bottom, and the lower limit section extends vertically from top to bottom, and the rear side wall of the limiting protrusion 2211 gradually extends obliquely inward from top to bottom into the first limiting groove 221, thereby realizing the adaptation of the shapes of the first limiting groove 221 and the rotating protrusion 212, so as to realize the upside and down flipping of the rotating protrusion 212 in the first limiting groove 221.

[0058] Furthermore, a first rotating cylinder 6 is connected to the rotating protrusion 212, and the first rotating cylinder 6 is arranged at the top of the support seat 22.

[0059] The first rotary cylinder 6 drives the rotary protrusion 212 to rotate in the up-down direction, and the second rotary cylinder 7 drives the rotary protrusion 212 to rotate in the left-right direction, thereby widening the rotation dimension of the rotary protrusion 212, and further widening the rotation dimension of the threading rod 1, enriching the braiding structure.

The motor is not shown in the accompanying drawings.

[0062] Specifically, the sliding protrusion can be arranged on the screw, and the screw drives the sliding protrusion to slide up and down on the vertical rod 8; the vertical opening 81 has a guiding effect on the sliding of the sliding protrusion to prevent the sliding protrusion from sliding out of position.
