After winding, in order to improve the surface quality and performance of the crucible sleeve, needle punching treatment is usually required. The needle punching process can effectively enhance the bonding force of carbon fibers and improve the compactness of its structure, thereby enhancing the durability and thermal shock resistance of the crucible sleeve. In addition, after winding, the upper and lower ends need to be cut off to form the shape of the crucible sleeve that meets the usage requirements. This cutting process not only helps to ensure the dimensional accuracy of the crucible sleeve, but also eliminates possible burrs and irregular edges, thereby improving its safety and reliability in actual use.

[0020] The mold 6 is fixed on the needle punching tooling. A wire feeder with a guiding function is provided on one side of the thread roller 8 close to the second movable plate 23, and the wire is evenly wound on the mold 6. At this time, the mold 6 is in a state parallel to the second movable plate 23 for winding the wire. Then, the up and down adjusting assembly 24 and the angle adjusting assembly 25 adjust the position of the mold 6, and the needle punching tooling and the mold 6 are driven to rotate by the rotating assembly 26, and the wire is wound up to form a carbon fiber crucible sleeve. The overall operation is simple, which is beneficial to reducing the labor intensity of workers and improving the production efficiency at the same time, and has strong practicability.

[0021] The adjustment mechanism 2 includes a first movable plate 22, a front-back adjustment assembly 21 installed at the bottom of the frame 1 and used to drive the first movable plate 22 to move back and forth, a second movable plate 23 arranged above the first movable plate 22, four equidistantly and symmetrically installed up-down adjustment assemblies 24 between the first movable plate 22 and the second movable plate 23 and used to drive the second movable plate 23 to move up and down, an angle adjustment assembly 25 installed on one side of one of the mounting brackets 5 and used to adjust the inclination angle of the mold 6, and a rotation assembly 26 installed between the two mounting brackets 5 and used to drive the mold 6 to rotate. The mounting bracket 5 is fixedly connected to the top of the second movable plate 23.

[0022] After the winding is completed, the product is lifted below the needle punching plate 7 through the up-down adjustment assembly 24, and the angle adjustment assembly 25 and the rotation assembly 26 can ensure that the needle can reach every position of the product.
