[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] like Figure 1-5As shown, this utility model proposes an insulated wire winding shaft for a crystalline silicon stretching device, comprising a wire winding support component, an inner insulating component, a transfer assembly component, and a protective insulating component. The wire winding support component is connected to a rotation drive device and has a guide space for winding the wire. The inner insulating component is located inside the wire winding support component and is connected to the rotation drive device, providing insulation for the wire winding support component. The transfer assembly component is connected to the wire winding support component, with one side contacting the inner insulating component, providing a connection space with the drive device. The protective insulating component is located inside the wire winding support component and is connected to the transfer assembly component, providing static electricity protection. The tension adjustment component is located on one side of the wire winding support component.

[0035] In this embodiment, the wire winding support component includes a wire winding shaft 110, which is cylindrical in shape. The wire winding shaft has a through hole 111, a countersunk hole 112 on one side, and a plurality of threaded holes 113 on one side of the countersunk hole. The outer surface of the wire winding shaft has a guide groove 114 for guiding the wire.

[0036] In this embodiment, the guide groove has a depth of 6.6 mm and a width of 10 mm. The inner side of the guide groove is provided with an arc surface, which guides the wire to ensure the uniformity and stability of the wire winding.

[0037] In this embodiment, the inner insulating component includes a central insulating sleeve 210 and an inner insulating sleeve 220. The central insulating sleeve is inserted into the through hole of the wire winding shaft. The central insulating sleeve is provided with an assembly hole 211 corresponding to the threaded hole. The inner insulating sleeve is disposed in the wire winding shaft. The inner side of the inner insulating sleeve is in contact with the central insulating sleeve, and the inner insulating sleeve insulates the inner side of the wire winding shaft. After the central insulating sleeve is inserted into the wire winding shaft, its length is slightly longer than the length of the through hole of the wire winding shaft, and it completely covers the inner side of the wire winding shaft, thereby ensuring the protection of the inner side of the wire winding shaft.

[0038] In this embodiment, the adapter assembly component includes a stainless steel sleeve 310, an insulating bushing 320, an insulating gasket 330, and a hexagon socket screw 340. The stainless steel sleeve is disposed inside the wire winding shaft body, and its outer side is connected to the central insulating sleeve and the inner insulating sleeve. The stainless steel sleeve has a stepped hole 311 corresponding to the position of the assembly hole. The outer side of the stainless steel sleeve has a set of threaded holes 312. The insulating bushing is disposed in the stepped hole of the stainless steel sleeve. The insulating gasket is disposed on one side of the insulating bushing. The hexagon socket screw is disposed in the insulating bushing. The hexagon socket screw and the threaded hole of the wire winding shaft body form a threaded engagement. The hexagon socket screw fixes the stainless steel sleeve in the wire winding shaft body. The hexagon socket screw engages with the insulating bushing and the insulating gasket. The hexagon socket screw does not contact the stainless steel sleeve. When the stainless steel sleeve is connected to the wire winding shaft body, the stainless steel will not transmit current and static electricity to the wire winding shaft body through the hexagon socket screw.

[0039] Example 2

[0040] like Figure 1-5 The difference between this embodiment and embodiment 1 is that in this embodiment, the protective insulating component includes an insulating cover plate 410, which is disposed on one side of the stainless steel sleeve. The insulating cover plate is provided with an assembly hole 411 corresponding to the position of the threaded hole 411, and the insulating cover plate seals the internal hexagon screw.

[0041] In one embodiment of this utility model, the insulating cover is made of polytetrafluoroethylene (PTFE), which can effectively block current and static electricity.

[0042] In this embodiment, the outer and inner surfaces of the winding spool are provided with a polytetrafluoroethylene coating 115 (not shown in the figure). The polytetrafluoroethylene coating has excellent insulation properties, and its insulation resistance value can reach more than 10 to the power of 13 Ω, which can effectively prevent current conduction. At the same time, it has a low coefficient of friction, which can reduce the friction between the yarn and the winding spool, reduce yarn wear, and thus increase the quality of the yarn.

[0043] The working principle of this utility model:

[0044] During operation, the central insulating sleeve is inserted into the winding spool, followed by the inner insulating sleeve. The inner and central insulating sleeves work together to insulate the inner side of the winding spool. Next, a stainless steel sleeve is placed into the winding spool, contacting both the inner and central insulating sleeves, preventing direct contact between the stainless steel sleeve and the winding spool. An insulating bushing and insulating washer are then inserted into the stepped holes of the stainless steel sleeve. A hexagonal socket screw is then inserted into the insulating bushing, engaging with the threaded hole of the winding spool to fix the stainless steel sleeve within the spool. Simultaneously, the insulating bushing prevents the hexagonal socket screw from contacting the stainless steel sleeve, ensuring it is only connected to the winding spool. This prevents current from being transmitted to the winding spool while the stainless steel sleeve is fixed in place. An insulating cover is then placed on one side of the stainless steel sleeve to protect the hexagonal socket screw. The drive device can be threaded into the threaded hole of the stainless steel sleeve, causing the drive device to rotate the stainless steel sleeve and the winding spool, thus winding the wire.
