[0032] The rotating shaft 22 is rotatably installed on the installation backplate 25, the adjusting plate 21 is fixedly installed on the rotating shaft 22, and the support roller 14 is slidably installed on the adjusting plate 21. The rotating shaft 22 can rotate on the installation backplate 25, thereby driving the adjusting plate 21 to rotate. The rotation of the adjusting plate 21 can drive the support roller 14 to slide along the first arc slot 26 and the second arc slot 27, thereby realizing flexible adjustment of the position of the support roller 14. In this way, the operator can easily remove the support roller 14 from the installation backplate 25, which facilitates the replacement of the weft yarn cylinder 16, improves the replacement efficiency, reduces the downtime of the equipment, and is conducive to improving the overall efficiency of textile production.
[0033] The circumferential surface of the supporting roller 14 is sleeved with the weft yarn cylinder 16, the weft yarn cylinder 16 is provided with the gasket 15 at the side end, the gasket 15 is slidingly installed through the supporting roller 14 of the circumferential surface, and is attached to the side end of the adjusting plate 21, the existence of the gasket 15 plays a buffering and positioning role, on the one hand, the friction between the weft yarn cylinder 16 and the adjusting plate 21 can be reduced, and the service life of the equipment can be prolonged; on the other hand, the installation position of the weft yarn cylinder 16 on the supporting roller 14 can be ensured to be accurate, and the conveying accuracy of the weft yarn in the weaving process can be ensured.
[0034] The limiting sliding plate 11 is fixedly installed with the tension spring 12, the tension spring 12 is fixedly installed with the circular top plate 13, the circular top plate 13 is attached to the weft yarn cylinder 16, the elastic force generated by the tension spring 12 acts on the weft yarn cylinder 16 through the circular top plate 13, the weft yarn cylinder 16 is pushed to be closely attached to the gasket 15 and the supporting roller 14, such a design can effectively avoid the left and right shaking of the weft yarn cylinder 16 in the operation process of the spinning machine, ensure that the weft yarn can be stably output in the weaving process, thereby improving the quality of the textile product and reducing the defective rate caused by unstable weft yarn.

[0036] Working principle:
[0037] Replacement operation: when the spinning machine needs to replace the weft yarn barrel 16, the user first pulls up the locking bolt 23, because the positioning plate 24 is made of high-friction material, a certain force needs to be applied to pull it out of the mounting back plate 25, after the positioning plate 24 is pulled out, the locking bolt 23 will be separated from the rotating shaft 22, at this time the rotating shaft 22 can be freely rotated, then the user rotates the adjusting plate 21, the adjusting plate 21 is fixedly connected with the rotating shaft 22, so when the adjusting plate 21 rotates, it will drive the supporting roller 14, the weft yarn barrel 16 and the limiting slide plate 11 to rotate together, in this process, the limiting slide plate 11 and the supporting roller 14 will make arc motion in the first arc-shaped groove 26 and the second arc-shaped groove 27 formed in the mounting back plate 25, because the inner diameter of the first arc-shaped groove 26 is smaller than that of the second arc-shaped groove 27, the limiting slide plate 11 will be limited after sliding into the second arc-shaped groove 27, and will not slide outwards, ensuring the stability of the movement, when the limiting slide plate 11 and the supporting roller 14 are rotated to a suitable position from the mounting back plate 25, the user pushes the supporting roller 14, and the supporting roller 14 can be pulled out of the adjusting plate 21, then the gasket 15 is disassembled, and the weft yarn barrel 16 can be easily removed, completing the replacement operation of the weft yarn barrel 16, when installing a new weft yarn barrel 16, the reverse steps can be performed.
[0038] After installation, the fixing and stability: after the installation of the new weft yarn barrel 16 is completed, the tension spring 12 fixed on the limiting slide plate 11 plays a role, the elastic force generated by the tension spring 12 will push the circular top plate 13, the circular top plate 13 is attached to the weft yarn barrel 16, thereby pushing the weft yarn barrel 16 to tightly attach to the gasket 15 and the supporting roller 14, this tightly attached state can effectively avoid the left and right shaking of the weft yarn barrel 16 during the operation of the spinning machine, ensuring that the weft yarn can be stably output during the weaving process, and improving the quality of the woven product.
