[0033] The positioning assembly 4 includes a placement plate 41, which is used to place a sliding bin 42, so that the sliding bin 42 can slide inside the placement plate 41. The sliding bin 42 is arranged in an array inside the placement plate 41. Two cavity areas are arranged inside the sliding bin 42 to limit the movement of the yarn clamping plate 44. The telescopic rod 43 is symmetrically arranged on the sliding bin 42, and the yarn clamping plate 44 is arranged on the other side of the telescopic rod 43. The yarn clamping plate 44 is used to place the yarn inside the yarn clamping plate 44 when the staff replenishes new yarn. It performs a clamping operation, and a U-shaped baffle 45 is arranged on the yarn clamping plate 44. The U-shaped baffle 45 is used to prevent the yarn from tilting when being placed, resulting in unstable clamping. The U-shaped baffle 45 passes through the yarn clamping plate 44 and is fixedly connected with the sliding bin 42. A positioning spring rod 46 is arranged outside the sliding bin 42. The positioning spring rod 46 is used to cooperate with the stop block 71 on the second cross plate 7 when the sliding bin 42 is moved and adjusted, so that the positioning spring rod 46 can be stuck on the guide ring on the second cross plate 7.

[0034] A spring 47 is sleeved on the outside of the telescopic rod 43, and the spring 47 is used to provide elastic force so that the yarn clamping plate 44 has sufficient squeezing force to firmly clamp the yarn. A sliding rod 48 is provided on the sliding bin 42, and a slider 481 is provided at the end of the sliding rod 48 away from the sliding bin 42. The sliding rod 48 is used to facilitate the movement of the sliding bin 42. An squeezing rod 49 is provided in the sliding bin 42, and one end of the squeezing rod 49 is a triangular block. During the downward movement of the squeezing rod 49, the yarn clamping plate 44 can be squeezed to separate the two. A sliding plate 491 is provided at the end of the squeezing rod 49 away from the sliding bin 42. The sliding plate 491 is engaged and slid with the squeezing rod 49, and the movement of the squeezing rod 49 can be ensured to be driven to move when the sliding plate 491 is displaced without affecting the movement of the squeezing rod 49.

[0035] A matching plate 441 is provided at one end of the yarn clamping plate 44 close to the squeezing rod 49, and the matching plate 441 has the same shape as the end in contact with the squeezing rod 49. The matching plate 441 is used to facilitate the squeezing rod 49 to be smoothly inserted into the gap of the yarn clamping plate 44 to separate the two yarn clamping plates 44. A limiting plate 442 is provided on the side of the matching plate 441 away from the yarn clamping plate 44. The limiting plate 442 is used to cooperate with the guide rail 423 to avoid angular deviation of the yarn clamping plate 44 when moving.

[0036] A sliding groove 421 is provided through the sliding bin 42, and the sliding groove 421 is slidably connected to the yarn clamping plate 44. A sliding groove 422 is provided inside the sliding bin 42, and the sliding groove 422 is slidably connected to the matching plate 441. A guide rail 423 is provided in the sliding bin 42, and the guide rail 423 slides with the limiting plate 442. The guide rail 423 is used to limit the limiting plate 442, so as to avoid angular deviation of the yarn clamping plate 44 under the limitation of the limiting plate 442.

[0037] The placement plate 41 is symmetrically provided with a rotating rod 493, one end of which is provided with a long plate 492, and the long plate 492 is in contact and plugged with the sliding plate 491.

The placement plate 41 is symmetrically provided with a matching rod 411, and a movable groove 412 is opened on the placement plate 41.

[0038] During use, when the yarn needs to be supplemented, the rotating rod 493 is rotated to push the sliding plate 491 downward through the drive of the elongated plate 492. Under the movement of the sliding plate 491, the two yarn clamping plates 44 are separated by the squeeze rod 49 connected by the snap-in connection. After the yarn clamping plates 44 are separated, the yarns are placed one by one in the middle of the yarn clamping plates 44, and then the rotating rod 493 is rotated again to release the contact between the squeeze rod 49 and the yarn clamping plates 44. The yarn clamping plates 44 are reset under the action of the spring 47 to clamp the yarn, and then the entire placement plate 41 is moved to the first first horizontal plate 5 through the drive assembly 3. At the top, the positioning spring rod 46 is driven to move by moving the sliding bin 42. When the positioning spring rod 46 slides against the stop block 71 on the second horizontal plate 7, it encounters the semi-shaped guide ring on the second horizontal plate 7. The positioning spring rod 46 will be against the inside of the guide ring. When moving, a certain resistance will be found, indicating that the positioning has been completed. Then each sliding bin 42 is positioned in this way. After the positioning is completed, the driving component 3 is started again to limit the limit groove 21, so that the entire placement plate 41 brings the yarn to the predetermined position, and then the first horizontal plate 5 is lowered and closed with the second horizontal plate 7 to avoid contact between the yarns, thereby completing the replenishment of the yarn.
