[0001] This utility model relates to the field of weaving machine technology, specifically a Li ethnic brocade weaving device that can increase the density of warp yarns. Background Technology
[0002] The traditional textile dyeing, weaving and embroidery techniques of the Li ethnic group are one of China's national intangible cultural heritages. They are traditional handicrafts of Li women in Hainan Province who use natural fibers such as cotton and hemp to make clothing and other daily necessities. Through long-term practice of recognizing and utilizing plant fibers and dyes, they have gradually developed and formed a complete system consisting of four types of techniques: spinning, dyeing, weaving and embroidery.
[0003] The existing Li ethnic brocade weaving devices have the following shortcomings:
[0004] When multiple warp rolls release the warp yarns, the distance between the released warp yarns is constant because the position of the warp rolls is fixed. Therefore, it is impossible to adjust the warp yarn density. Thus, a Li ethnic brocade weaving device that can increase the warp yarn density is needed. Utility Model Content
[0005] In view of the problems existing in the existing Li ethnic brocade weaving device that can increase the warp density, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a Li ethnic brocade weaving device that can increase warp density. This solves the problem that in existing Li ethnic brocade weaving devices, when multiple warp rolls are released, the distance between the released warp yarns is constant because the position of the warp rolls is fixed, thus making it impossible to adjust the warp density. Therefore, it is necessary to set up a Li ethnic brocade weaving device that can increase warp density.
[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:
[0008] A Li ethnic brocade weaving device that can increase warp density includes a weaving machine body, on which a warp density adjustment mechanism is provided, which can adjust the distance between two adjacent warp yarns.

[0013] The top of the main body of the braiding machine is welded with a second support connecting seat, and a second support rod is inserted into the inner wall of the second support connecting seat. The second support rod and the second support connecting seat are fixed together by bolts.
[0014] The top of the main body of the weaving machine is welded with a third support connector, and a third support rod is inserted into the inner wall of the third support connector. The third support rod and the third support connector are fixed together by bolts.
[0015] As a preferred embodiment of the Li ethnic brocade weaving device that can increase warp density according to the present invention, wherein: a warp tension adjustment mechanism is installed on the second support rod;
[0016] The warp tension adjustment mechanism includes a damper mounted on a second support rod, a spring sleeved on the damper, and a U-shaped block connected to the other end of the damper.
[0017] As a preferred embodiment of the Li ethnic brocade weaving device that can increase warp density according to the present utility model, wherein: a seventh support connecting seat is welded on the second support rod, a damper is inserted into the inner wall of the seventh support connecting seat, and the damper and the seventh support connecting seat are fixed by bolts;
[0018] A fourth support connector is welded onto the U-shaped block. A damper is inserted into the inner wall of the fourth support connector, and the fourth support connector and the damper are fixed together by bolts.
[0019] As a preferred embodiment of the Li ethnic brocade weaving device that can increase warp density according to the present invention, the warp density adjustment mechanism includes a fixed block welded to a third support rod, an electric push rod installed on the fixed block, and a second threading spool welded to the other end of the electric push rod, through which the warp yarn passes.

[0022] Compared with existing technologies:
[0023] 1. By setting up a warp density adjustment mechanism, each electric push rod retracts, causing the threading bobbin to move, thereby bringing the warp yarns closer together and increasing the warp density, thus enabling the adjustment of warp density.
[0024] 2. By setting up a warp tension adjustment mechanism, the U-shaped block presses against the warp yarn, and the damper and spring are both in a compressed state. When the warp yarn is loose, the elasticity of the damper and spring can tighten the yarn; when the warp yarn is too tight, the damper and spring will be further compressed by the warp yarn, thus making the warp yarn looser. This ensures that the warp yarn tension is appropriate and also ensures the stability of the distance between each warp yarn after weaving, thereby further ensuring the reliability of warp density adjustment.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0031] This utility model provides a weaving device for Li ethnic brocade that can increase warp density. Please refer to [link / reference]. Figure 1-4 It includes a braiding machine body 1, which is equipped with a warp density adjustment mechanism. The distance between two adjacent warp yarns can be adjusted through the warp density adjustment mechanism.
[0032] The top of the main body 1 of the braiding machine has a yarn winding frame 2, on which a warp yarn roll 3 is installed, and warp yarn 7 is wound on the warp yarn roll 3.
[0033] The top of the braiding machine body 1 is equipped with a first support rod 4, a second support rod 5, and a third support rod 6. Specifically, a first support connecting seat 41 is welded to the top of the braiding machine body 1, and the first support rod 4 is inserted into the inner wall of the first support connecting seat 41. The first support rod 4 and the first support connecting seat 41 are fixed together by bolts. A second support connecting seat 51 is welded to the top of the braiding machine body 1, and the second support rod 5 is inserted into the inner wall of the second support connecting seat 51. The second support rod 5 and the second support connecting seat 51 are fixed together by bolts. A third support connecting seat 61 is welded to the top of the braiding machine body 1, and the third support rod 6 is inserted into the inner wall of the third support connecting seat 61. The third support rod 6 and the third support connecting seat 61 are fixed together by bolts. A first threading bobbin 8 is welded onto the first support rod 4, and the warp yarn 7 passes through the first threading bobbin 8.
[0034] A warp tension adjustment mechanism is installed on the second support rod 5. The warp tension adjustment mechanism includes a damper 11 installed on the second support rod 5. Specifically, a seventh support connecting seat 13 is welded to the second support rod 5. The damper 11 is inserted into the inner wall of the seventh support connecting seat 13. The damper 11 and the seventh support connecting seat 13 are fixed together by bolts. A spring 12 is sleeved on the damper 11. A U-shaped block 9 is connected to the other end of the damper 11. Specifically, a fourth support connecting seat 10 is welded to the U-shaped block 9. The damper 11 is inserted into the inner wall of the fourth support connecting seat 10. The fourth support connecting seat 10 and the damper 11 are fixed together by bolts. The U-shaped block 9 presses against the warp 7, and both the damper 11 and the spring 12 are in a compressed state. When the warp 7 is relaxed, the elastic force of the damper 11 and the spring 12 can tighten the warp 7.
[0035] The warp density adjustment mechanism includes a fixing block 14 welded to the third support rod 6. An electric push rod 16 is installed on the fixing block 14.

The sixth support connecting seat 17 and the electric push rod 16 are fixed together by bolts. The warp yarn 7 passes through the second threading tube 18.
[0036] In practical use, the U-shaped block 9 presses against the warp yarn 7, and the damper 11 and spring 12 are both in a compressed state. When the warp yarn 7 is relaxed, the elastic force of the damper 11 and spring 12 can tighten the yarn 7. When the warp yarn 7 is too tight, the damper 11 and spring 12 will be further compressed by the warp yarn 7, thereby making the warp yarn 7 looser.
[0037] Each electric push rod 16 retracts, causing the second threading spool 18 to move, thereby bringing the warp yarns 7 closer together and increasing the warp density.
