[0033] The following is combined with Figure 1 —5 further describes this application in detail.

[0034] The embodiment of the present application discloses a seamless underwear knitting machine head.

[0035] The observation view of this device (front, back, left, right) is as follows Figure 1 For reference benchmark.

[0036] Reference Figure 1 , 2 A seamless underwear machine head includes a sleeve 1, an extension mechanism 2, a circular groove 201 formed on the lower surface of the sleeve 1, a square groove 202 formed on the upper end surface of the circular groove 201, an outer wall of a sliding column 203 is slidably connected to the bottom of the circular groove 201, two ends of a sliding sheet 204 are respectively fixedly connected to the upper end of the sliding column 203 and the lower end of a groove block 205, an outer wall of the sliding sheet 204 slides inside the circular groove 201, and an upper end of the groove block 205 is slidably connected to the inner surface of the square groove 202. The symmetrical path array on one side of the extension block 206 is fixedly connected to the inside of the groove block 205, one end of the L-shaped block 207 is movably passed through both sides of the sleeve 1, and the other end of the L-shaped block 207 is slidably connected between the two extension blocks 206. A round groove 208 is opened on one side of an L-shaped block 207, and two ends of the spring 209 are respectively fixedly connected to the inside of the round groove 208 and one side of the fixed column 210, and the other side of the fixed column 210 is fixedly connected to one side of another L-shaped block 207.

[0037] When the operator needs to adjust the height of the needle, the operator manually or mechanically installs the sleeve 1 on the machine head, and then manually squeezes the L-shaped blocks 207 on both sides of the sleeve 1. Through the sliding of the L-shaped blocks 207, the fixed column 210 begins to slide inside the circular groove 208, and the spring 209 begins to shrink. At the same time, the other end of the L-shaped block 207 begins to slide between the two extension blocks 206. When the two L-shaped blocks 207 slide out of the extension blocks 206, the height of the needle can be adjusted.

[0038] When the needle height is adjusted, the operator manually loosens the L-shaped block 207. Through the elasticity of the round through groove 208, the round through groove 208 starts to push the fixed column 210, so that the L-shaped block 207 is re-locked in the extension block 206. When the L-shaped block 207 is locked inside the extension block 206, the height adjustment is completed.

[0039] Reference Figure 1 , 34, 5, the fixing mechanism 3 includes a circular groove 2 301 opened at the bottom of the sliding column 203, a round groove 2 302 opened at the center of the top surface of the circular groove 2 301, an annular groove 1 303 opened outside the round groove 2 302 on the top surface of the circular groove 2 301, a bottom outer side of the ladder block 304 is rotatably connected and clamped at the lower end of the circular groove 2 301, a lower end of the bevel gear 1 305 is fixedly connected to the outer upper surface of the ladder block 304, and a fixed column 2 306 is provided. The first end is fixedly connected to the inside of the bevel gear 305 on the upper surface of the step block 304, the other end of the fixed column 306 is rotatably connected and clamped in the inside of the annular groove 303, the upper end of the track block 307 is fixedly connected to the lower end of the step block 304, the outer wall of the T-shaped block 308 movably passes through the bottom of the circular groove 301, the bottom of the curved block 309 is fixedly connected to the top side of the T-shaped block 308, and the outside of the curved block 309 is slidably connected and clamped in the inside of the track block 307.

[0040] The upper end of the fixed block 310 is fixedly connected to the outside of the annular groove 303 on the top surface of the circular groove 301, and the internal thread groove 311 is non-penetratingly opened on the bottom side of the fixed block 310. The upper end of the fixed block 312 is fixedly connected to one side of the fixed block 310 on the top surface of the circular groove 301. The outer wall of the rotating column 313 movably penetrates the lower end of the sliding column 203. The annular groove 314 is opened on the outer wall of one side of the rotating column 313. The annular groove 314 is clamped at the bottom of the fixed block 312. One side of the bevel gear 315 is fixedly connected to one side of the rotating column 313. The lower end of the bevel gear 315 is meshed with one side of the bevel gear 305. The circular through hole 316 is penetrated and opened in the middle of the rotating column 313 and the bevel gear 2 315. The middle part of the threaded column 317 is rotatably connected to the inside of the circular through hole 316, and one end of the threaded column 317 is meshed with the inside of the internal thread groove 311.

[0041] When the operator is installing the needle, the operator first rotates all the threaded columns 317 out of the inner thread groove 311 through the hexagonal block, and then manually passes the replaced needle tail through the step block 304 to abut against the inner wall of the round groove 2 302. At this time, rotate any rotating column 313. Through the rotation of the rotating column 313, the bevel gear 2 315 begins to rotate with the bevel gear 1 305. Through the rotation of the bevel gear 1 305, the fixed column 2 306 begins to rotate inside the annular groove 1 303, and the curved block 309 inside the track block 307 begins to slide. Through the sliding of the track block 307, the T-block 308 begins to slide at the bottom of the sliding column 203. Through the sliding of the T-block 308, the needle can be clamped or not.

[0042] After completing the replacement and fixation of the needle, the operator manually places the threaded column 317 in the circular hole 316 through the hexagonal block, and then rotates the threaded column 317 to fix the threaded column 317 inside the internal thread groove 311. The fixation of the threaded column 317 can prevent the rotation of the bevel gear 2 315, thereby ensuring stability during operation.

[0043] The implementation principle of a seamless underwear machine head in an embodiment of the present application is as follows: the operator fixes the sleeve 1 at the machine head, then takes out the threaded column 317 from the inner thread groove 311, places the needle tail against the round groove 2 302, and then rotates the rotating column 313 to make the bevel gear 2 315 rotate with the bevel gear 1 305, and fixes the needle head with the T-shaped block 308 through the curved block 309 inside the track block 307, and finally manually rotates the threaded column 317 to fix the rotating column 313 to complete the fixation or replacement of the needle head.

[0044] When the height of the needle needs to be adjusted, the operator manually squeezes the L-shaped blocks 207 on both sides of the sleeve 1 to make the L-shaped blocks 207 slide out of the extension block 206. After the L-shaped blocks 207 slide out of the extension block 206, the height of the sliding column 203 and the needle can be adjusted. After the adjustment is completed, the L-shaped blocks 207 can be manually released to fix the adjusted height.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
