[0002] An enameling machine is a large-scale, continuous, and precision wire and cable production equipment specifically designed for manufacturing enameled wires. Its core function is to uniformly coat the surface of a metal conductor (such as copper or aluminum wire) with an extremely thin, tough, and smooth insulating varnish film, and then cure it at high temperatures.

[0003] For example, a wire tensioning device for an enameling machine, as disclosed in Chinese Patent Publication No. CN214312769U, includes a base, a slide rail arranged along the tensioning direction, a slide block slidably arranged on the slide rail, an adjustment channel and an adjustment groove connecting the adjustment channel to the outside along the tensioning direction, a pusher seat, an adjustment seat, a mechanical pressure gauge and an adjustment screw slidably arranged in the adjustment channel, a tensioning spring fixed to a spring mounting post forming a fixed fit with the base, the pusher seat sliding in the adjustment channel, the adjustment screw arranged along the adjustment channel and rotatingly fitted with the base, one end of the adjustment screw located in the adjustment channel as a transmission end threadedly fitted with the pusher seat, and the other end extending outside the base as an operating end driving its rotation, the mechanical pressure gauge fixed to the pusher seat, and the detection end of the mechanical pressure gauge abutting against the adjustment seat.

[0004] In existing enameling machines, the tensioning wheel is made of metal, which causes varying degrees of wear on the lead wire when it comes into contact with the tensioning wheel due to increased pressure. This affects the lead wire's condition in subsequent use. Therefore, an improved device is needed to address this problem. Utility Model Content

[0020] Please see Figure 1-4 This utility model provides an embodiment of a wire tensioning device for an enameling machine, comprising a support device 3, a displacement device 2 slidably sleeved at the top of the support device 3, and a contact device 1 fixedly installed at the side end of the displacement device 2. The contact device 1 includes a support plate 4, a screw 5, a positioning plate 6, a nut 7, a sleeve 8, a plastic sleeve 9, and a central machine shaft 10. The central machine shaft 10 is fixedly installed at the center of the side end of the support plate 4, the screw 5 is fixedly installed at the center of the side end of the central machine shaft 10 away from the support plate 4, the sleeve 8 is slidably sleeved on the outer ring of the central machine shaft 10, the plastic sleeve 9 is slidably sleeved on the outer ring of the sleeve 8, the positioning plate 6 is slidably sleeved on the outer ring of the screw 5 away from the support plate 4, and the nut 7 is threadedly sleeved on the outer ring of the screw 5, and the nut 7 is located on the side end of the positioning plate 6 away from the central machine shaft 10.

[0021] The displacement device 2 includes a displacement bracket 11 and a bearing 12. The bearing 12 is fixedly installed inside the side end of the displacement bracket 11. The support device 3 includes a drive motor 13, a guide rod 14, a lead screw 15, a support side plate 16, a mating base plate 17, and a spool 18. The spool 18 is symmetrically and rotatably installed on one side of the support side plate 16. The drive motor 13 is fixedly installed at the bottom end of the other side of the support side plate 16. The lead screw 15 is fixedly installed at the top center of the drive motor 13. The mating base plate 17 is fixedly installed at the top center of the support side plate 16. The guide rod 14 is symmetrically and fixedly installed at the bottom end of the mating base plate 17. When the drive motor 13 is turned on, it can drive the lead screw 15 to rotate in both directions, so that the displacement bracket 11 can move up and down.

[0022] The displacement bracket 11 is threaded onto the outer ring of the lead screw 15, and the support plate 4 is fixedly installed inside the bearing 12, which can support the rotation of the support plate 4.

[0023] The outer rings of the central shaft 10 and the sleeve 8 are provided with slots, and the inner rings of the sleeve 8 and the inner rings of the plastic sleeve 9 are fixedly installed with key, which facilitates the disassembly and assembly of the plastic sleeve 9 and the sleeve 8.

[0024] A threaded hole is provided at the center of the top of the displacement bracket 11, and round holes are provided at both ends of the top of the displacement bracket 11 to facilitate the up and down movement of the displacement bracket 11.

[0025] The positioning disk 6 has a through hole in the center of its interior, which facilitates the assembly and disassembly of the positioning disk 6.

[0026] Working Principle: In use, the support side plate 16 is first installed on the outer surface of the enameling machine. Then, the external lead wire passes through the top of the wire wheel 18 and the bottom of the plastic sleeve 9. When the enameling machine is feeding the lead wire, the drive motor 13 can be turned on to drive the lead screw 15 to rotate. The center thread of the displacement bracket 11 is connected to the outer ring of the lead screw 15, so that when the lead screw 15 rotates, it can drive the displacement bracket 11 to move up and down. When the displacement bracket 11 is displaced, it can drive the support plate 4 to move until the plastic sleeve 9 moves to contact the lead wire. Thus, the plastic sleeve 9 can press and tension the lead wire. Through the setting of the plastic sleeve 9, the wear phenomenon of the lead wire can be prevented. Furthermore, a connecting rod is fixedly installed on the side end of the support plate 4 away from the center shaft 10, and the connecting rod is installed inside the bearing 12. Thus, the connecting rod can be located inside the bearing 12 to support the rotation of the support plate 4, improving the smoothness of the lead wire passing through the plastic sleeve 9. The two ends of the displacement bracket 11 are slidably connected to the guide rod 14. On the outer ring, this ensures that the displacement bracket 11 moves up and down in a straight line to complete the tensioning of the lead wire. Subsequently, when the plastic sleeve 9 is excessively worn and needs to be replaced, the nut 7 can be turned until it is removed from the outer ring of the screw 5, the positioning plate 6 can be released, and then the positioning plate 6 can be pulled away from the end away from the support plate 4 until the positioning plate 6 is removed from the outer ring of the screw 5. Then the plastic sleeve 9 can be removed from the outer ring of the sleeve 8 and pulled out. Then the new plastic sleeve 9 can be moved to the sleeve 8. On the outer ring, the plastic sleeve 9 slides in the groove on the outer ring of the sleeve 8 via the key on the inner ring, which improves the installation accuracy of the plastic sleeve 9 and prevents the plastic sleeve 9 from rotating when it comes into contact with the lead wire. Then, the positioning plate 6 is slidably fitted onto the screw 5, and the nut 7 is installed on the screw 5 until the nut 7 is tightened to be secure with the positioning plate 6. This can press the positioning plate 6 into contact with the side of the central machine shaft 10 away from the support plate 4, thus completing the replacement of the plastic sleeve 9.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
