[0030] The limiting mechanism 3 includes a driving part 31 and a limiting part 32;

[0031] The limiting part 32 is located on the front side of the drive part 31.

[0032] The conveying unit 21 includes two side plates 211, which are arranged on the left and right sides. The side plates 211 are fixedly connected to the worktable 1. Each side plate 211 has a fixed seat 212 on its rear side, which is fixedly connected to the side plate 211. Each fixed seat 212 has a motor 213 on its top surface, which is fixedly connected to the fixed seat 212.

[0033] The output end face of motor 213 extends through to the front side of side plate 211. Motor 213 is rotatably connected to side plate 211. A conveying roller 214 is fixedly installed on the output end face of motor 213 on the left side, and a conveying wheel 215 is installed on the output end face of motor 213 on the right side.

[0034] The tension adjustment unit 22 includes a vertical plate 221, which is fixedly connected to the worktable 1. A portal plate 222 is provided on the top surface of the vertical plate 221, and the portal plate 222 is fixedly connected to the vertical plate 221. A second motor 223 is provided on the inner side of the portal plate 222, and the second motor 223 is fixedly connected to the portal plate 222. A lead screw 224 is provided on the output end face of the second motor 223, and the lead screw 224 is fixedly connected to the second motor 223. The lead screw 224 extends through to the inner side of the vertical plate 221 and is threadedly connected to the inner wall of the vertical plate 221.

[0035] The bottom end face of the lead screw 224 is rotatably connected to the inner side of the vertical plate 221 through a bearing seat. Threaded blocks 225 are fitted on the surface of the lead screw 224. The threaded blocks 225 are threadedly connected to the lead screw 224. A straight plate 226 is provided on the front side of the threaded block 225. The straight plate 226 is fixedly connected to the threaded block 225. A slider 227 is fixedly provided on the rear side of the straight plate 226. A guide wheel 228 is provided on the front side of the slider 227. The guide wheel 228 is movably connected to the straight plate 226. A guide rod 229 is provided on the rear side of the guide wheel 228.

The outer end face of the guide rod 229 is fixedly connected to the inner side of the vertical plate 221.

[0036] Furthermore, in this embodiment, the tension adjustment mechanism 2 utilizes the conveying rollers 214 and 215 in the conveying section 21. The wire passes through the conveying rollers 214, guide wheels 228, and conveying wheels 215 in the conveying section 21. The motor 213 is started, and the motor 213 drives the conveying rollers 214 and 215 to rotate, thereby conveying the wire. When the tension is too low during the conveying process, the motor 223 is started, and the motor 223 drives the lead screw 224 to rotate. The rotation of the lead screw 224 further drives the threaded block 225 to move on the lead screw 224. The movement of the threaded block 225 drives the connected plate 226 and guide wheel 228. Under the action of the slider 227, the plate 226 and guide wheel 228 slide and rise along the surface of the guide rod 229. The rise of the guide wheel 228 changes the path of the wire, thereby increasing the tension of the wire.

[0037] Furthermore, in this embodiment, the tension adjustment mechanism 2 utilizes the conveying roller 214 and conveying wheel 215 in the conveying section 21 to pass the yarn through the conveying roller 214, guide wheel 228, and conveying wheel 215, thereby activating motor 213. Motor 213 drives the conveying roller 214 and conveying wheel 215 for conveying. When the tension is too low, motor 223 is activated. Motor 223 drives the lead screw 224, which drives the threaded block 225. The threaded block 225 drives the straight plate 226 and guide wheel 228 to slide on the surface of guide rod 229 under the action of slider 227, thereby increasing the tension and ensuring that the weft yarn maintains a constant tension during the weaving process to ensure the quality and uniformity of the textile.

[0038] Example 2:

[0039] Please see Figure 1 , Figure 2 , Figure 4Furthermore, based on Embodiment 1, the following is obtained: the drive unit 31 includes a placement column 311, the bottom surface of the placement column 311 is fixedly connected to the top surface of the workbench 1, an L-shaped plate 312 is provided on the top surface of the placement column 311, the L-shaped plate 312 is fixedly connected to the placement column 311, and a motor 313 is provided on the inner side of the L-shaped plate 312, the motor 313 is fixedly connected to the L-shaped plate 312.

[0040] The limiting part 32 includes a bidirectional threaded rod 321. The top surface of the bidirectional threaded rod 321 is fixedly connected to the output end face of the motor 313. The bidirectional threaded rod 321 extends through to the inner side of the placement column 311. The bidirectional threaded rod 321 is threadedly connected to the inner wall of the placement column 311. The bottom surface of the bidirectional threaded rod 321 is rotatably connected to the inner side of the placement column 311 through the bearing seat 2. T-shaped threaded blocks 322 are fitted on the surface of the bidirectional threaded rod 321. The T-shaped threaded blocks 322 are threadedly connected to the bidirectional threaded rod 321. Limiting wheels 323 are movably provided on the front side of the T-shaped threaded blocks 322.

[0041] Furthermore, in this embodiment, through the limiting mechanism 3, the motor 313 in the drive unit 31 is used. During the normal weaving process, the weft yarn runs in the device according to a predetermined path. When the weft yarn passes through the limiting mechanism 3, the motor 313 is started. After the motor 313 starts working, it drives the bidirectional threaded rod 321 to rotate. The rotation of the bidirectional threaded rod 321 causes the T-shaped threaded block 322 to move on the rod. The movement of the T-shaped threaded block 322 further drives the limiting wheel 323 to move to a predetermined position. The position adjustment of the limiting wheel 323 enables it to contact and restrict the further movement of the weft yarn.

[0042] Furthermore, in this embodiment, the limiting mechanism 3 utilizes the motor 313 in the drive unit 31. When the thread crosses the limiting mechanism 3, the motor 313 is activated. The motor 313 drives the bidirectional threaded rod 321, which in turn drives the T-shaped threaded block 322. This causes the T-shaped threaded block 322 to drive the limiting wheel 323 to limit the weft thread and prevent it from falling out of the device.

[0043] In use, the tension adjusting mechanism 2 utilizes the conveying rollers 214 and 215 in the conveying section 21. The wire passes through the conveying rollers 214, guide wheels 228, and conveying wheels 215 in the conveying section 21. Motor 1 213 is started, driving the conveying rollers 214 and 215 to rotate, thus conveying the wire. If the tension is too low during conveying, motor 223 is started, driving the lead screw 224 to rotate. The rotation of the lead screw 224 further drives the threaded block 225 to move on the lead screw 224. The movement of the threaded block 225 drives the connected straight plate 226 and guide wheels 228. Under the action of the slider 227, the straight plate 226... The guide wheel 228 slides and rises along the surface of the guide rod 229. The rise of the guide wheel 228 changes the path of the yarn, thereby increasing the tension of the yarn. Through the limiting mechanism 3, the motor 313 in the drive unit 31 drives the weft yarn to run along a predetermined path in the device during normal weaving. When the weft yarn passes through the limiting mechanism 3, the motor 313 is started. After the motor 313 starts working, it drives the bidirectional threaded rod 321 to rotate. The rotation of the bidirectional threaded rod 321 causes the T-shaped threaded block 322 to move on the rod. The movement of the T-shaped threaded block 322 further drives the limiting wheel 323 to move to a predetermined position. The position adjustment of the limiting wheel 323 enables it to contact and restrict the further movement of the weft yarn.
