[0029] Example 1

[0030] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a tension adjustment device for core-spun yarn elastic yarn, which enables convenient replacement of the guide wheel 201. It includes a drafting rod 100 installed on a CNC core-spun yarn machine. The outer peripheral wall of the drafting rod 100 is provided with an adjusting traction frame 200 and a guide wheel 201.

[0031] Assembly component 300 is disposed between the adjusting traction frame 200 and the guide wheel 201. Assembly component 300 includes a stabilizer bar 301, an assembly part 303 and a fastener 305.

[0032] The stabilizer bar 301 is inserted into the top of the guide wheel 201, the fitting 303 is snapped into the side wall of the guide wheel 201 to limit the guide wheel 201, and the fastener 305 is inserted into the side wall of the fitting 303 to fix the fitting 303.

[0033] In use, by rotating the fixing part 305 outward, the assembly 303 can be opened, which facilitates the quick disassembly and replacement of the worn guide wheel 201, avoiding the current situation where the guide wheel 201 is inconvenient to disassemble and replace, and improving its replacement efficiency.

[0034] Example 2

[0035] Reference Figures 1 to 4 This is the second embodiment of the present invention. Unlike the previous embodiment, the stabilizing rod 301 is fixedly connected to the bottom of the adjusting traction frame 200, and the top of the guide wheel 201 is provided with a stabilizing hole 301a. The stabilizing rod 301 is inserted into the inside of the stabilizing hole 301a. The stability of the guide wheel 201 after installation is improved by the stabilizing rod 301.

[0036] The bottom of the adjusting traction frame 200 is fixedly connected to a shaft 302, and the assembly 303 is rotatably connected to the outer peripheral wall of the shaft 302. A flexible pad 303a is fixedly connected to the side wall of the assembly 303. The flexible pad 303a abuts against the outer wall of the guide wheel 201, and the tightness of fixing the guide wheel 201 is improved by the flexible pad 303a.

[0037] The assembly 303 has a connector 304 fixedly connected to its side wall. The bottom of the adjusting traction frame 200 has a connecting groove 304a. The connector 304 is inserted into the connecting groove 304a. The side wall of the connector 304 has a fixing hole 305a. The fixing member 305 is threadedly connected to the side wall of the adjusting traction frame 200 and is inserted into the fixing hole 305a. By rotating the assembly 303 upward until the connector 304 on the assembly 303 is inserted into the connecting groove 304a, and then rotating the fixing member 305 inward until the fixing member 305 is inserted into the fixing hole 305a on the connector 304, the assembly 303 can be sealed and fixed.

[0038] The adjustable traction frame 200 is slidably connected to the outer peripheral wall of the extension rod 100. The top of the adjustable traction frame 200 is threadedly connected to a limiting member 306, and the bottom of the limiting member 306 is fixedly connected to a rubber pad 307. The rubber pad 307 abuts against the outer wall of the extension rod 100. By rotating the limiting member 306 upward, the distance between multiple sets of adjustable traction frames 200 can be moved. Then, by rotating the limiting member 306 downward until the rubber pad 307 abuts against the outer wall of the extension rod 100, the adjustable traction frame 200 can be limited.

[0039] In use, by rotating the fixing part 305 outward, the assembly 303 can be rotated downward to open it. At this time, the worn guide wheel 201 can be disassembled and replaced. Then, the new guide wheel 201 is inserted into the outer wall of the stabilizing rod 301, and the assembly 303 is rotated upward until the connecting part 304 on the assembly 303 is inserted into the connecting groove 304a. Then, the fixing part 305 is rotated inward until the fixing part 305 is inserted into the fixing hole 305a on the connecting part 304, which can close and fix the guide wheel 201. Finally, when the core-spun yarn is being drawn, the tension of the core-spun yarn can be adjusted by adjusting the position of the drawing rod 100 and the drawing frame 200.

[0040] It is worth noting that the specific functions and operating principles of the adjusting draft rod 100 and adjusting traction frame 200 on the above-mentioned CNC core-spun yarn equipment can be referenced from the CNC core-spun yarn equipment with model number ZP-40.
