[0002] A circular knitting machine, scientifically named a circular weft knitting machine, mainly consists of a frame, a yarn feeding mechanism, a transmission mechanism, a lubrication and dust removal (cleaning) mechanism, an electrical control mechanism, a pulling and winding mechanism, and other auxiliary devices. Circular knitting machines can be divided into two major categories: single-sided series and double-sided series. Due to the circular knitting machine having many loop-forming systems (referred to as the number of yarn feeding paths or loop-forming paths in enterprises, abbreviated as the number of paths), high rotational speed, high output, fast pattern change, good fabric quality, few processes, and strong product adaptability, it has developed rapidly.

[0003] Several groups of needles are installed on the circular knitting machine, and embroidery processes are performed on the fabric through the needles. However, the needles have high requirements during processing and need to be detected. Currently, most needle detections are to place the needles one by one on the detection tabletop, and the defective products are detected through the detection module.

A second pulley 207 is fixedly connected to one end of the driving rod 208. The rotation of the driving rod 208 causes the second pulley 207 to rotate. A transmission belt 206 is sleeved on the second pulley 207, and the other end of the transmission belt 206 is sleeved on the first pulley 205.

By rotating the rotating cylinder 301, the scraper 314 scrapes the needles adsorbed on the surface of the suction plate 303, avoiding affecting the later detection efficiency of the needles.

[0026] As an implementation mode in this embodiment, the detection component includes a processing table 4 fixedly connected to the other side of the top surface of the device body 1. A limit seat 401 is fixedly connected to the processing table 4. A roller 402 is rotatably connected to the limit seat 401. One end of the roller 402 is fixedly connected to the output end of a third motor 403. The third motor 403 is fixedly connected to the limit seat 401. A pair of rollers 402 are provided.

The third shaft seat 416 is fixedly connected to the surface of the placement board 406.

[0027] Specifically, place the needle on the material belt 404. Through the operation of the third motor 403, the material belt 404 moves the needle to the bottom position of the detection board 101. Then, the fourth motor 407 starts to operate. Through the operation of the fourth motor 407, the disc 409 on the main shaft 408 rotates. The rotation of the disc 409 pushes the detection board 101 to move through the linkage plate 411 on the plug post 410. The movement of the detection board 101 causes the pulley 414 on the bracket 413 to slide on the slide bar 415, increasing the stability of the movement of the detection board 101. Through the movement of the detection board 101, the detection module 102 detects the quality of the needles on the material belt 404.

[0028] The working principle of the present invention: When it is necessary to move the position of the transfer table 213, the first motor 209 operates. The operation of the first motor 209 causes the driving rod 208 to rotate. A second pulley 207 is fixedly connected to one end of the driving rod 208. The rotation of the driving rod 208 causes the second pulley 207 to rotate. A transmission belt 206 is sleeved on the second pulley 207, and the other end of the transmission belt 206 is sleeved on the first pulley 205. The rotation of the second pulley 207 drives the first pulley 205 to rotate through the transmission belt 206, thereby facilitating the rotation of the rotating rod 204 on the first pulley 205. Arm plates 210 are fixedly connected to both ends of the rotating rod 204, and the other ends of the arm plates 210 are rotatably connected to the docking rod 211. The rotation of the rotating rod 204 facilitates the movement of the position of the transfer table 213; A rotating cylinder 301 is provided on the transfer table 213, and a second motor 302 is detachably installed on the rotating cylinder 301. A receiving groove 304 is formed in the second motor 302, and an electromagnet 305 is installed inside the receiving groove 304. When the electromagnet 305 is energized, it will adsorb the needles inside the box body 202. However, some needles will be adsorbed on the surface of the suction plate 303. By rotating the rotating cylinder 301, the scraping plate 314 scrapes the needles adsorbed on the surface of the suction plate 303 to avoid affecting the later detection efficiency of the needles. Place the needles on the material belt 404. Through the operation of the third motor 403, the material belt 404 moves the needles to the bottom position of the detection plate 101. Then the fourth motor 407 starts to operate. Through the operation of the fourth motor 407, the disk 409 on the main shaft 408 rotates. The rotation of the disk 409 pushes the detection plate 101 to move through the linkage plate 411 on the insertion post 410. The movement of the detection plate 101 causes the pulley 414 on the bracket 413 to slide on the slide rod 415, increasing the stability of the movement of the detection plate 101. Through the movement of the detection plate 101, the detection module 102 detects the quality of the needles on the material belt 404.

[0029] The present invention also provides a method for detecting needles of a circular knitting machine, including: S1. Place the processed needles inside the box body 202. Move the transfer table 213 inside the box body 202 through the transfer assembly. Rotate the rotating cylinder 301 to make the electromagnet 305 inside the receiving groove 304 adsorb the needles inside the box body 202. S2. When the rotating cylinder 301 rotates, scrape the needles adsorbed on the surface of the suction plate 303 through the scraping plate 314 to avoid affecting the later detection of the needles. S3. Finally, move the needles to the upper position of the material belt 404 through the transfer assembly. At this time, the electromagnet 305 is powered off and loses its magnetism, and the needles inside the receiving groove 304 will fall onto the material belt 404. The material belt 404 moves the needles to the bottom surface position of the detection plate 101 for step-by-step detection work.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.

The other end of the linkage plate (411) is rotatably connected to a second hinge seat (412). The second hinge seat (412) is fixedly installed on the detection plate (101). A pair of brackets (413) are fixedly connected to the top surface of the detection plate (101). A pulley (414) is rotatably connected to the pair of brackets (413). The pulley (414) is slidably connected to a slide bar (415). The two ends of the slide bar (415) are fixedly connected to a third shaft seat (416). The third shaft seat (416) is fixedly connected to the surface of the placing plate (406).

10. A method for detecting knitting circular machine needles, based on any one of claims 1-9, includes: S1. Place the processed needles inside the box body (202). Move the transfer table (213) inside the box body (202) through the transfer assembly. Rotate the rotating cylinder (301) to make the electromagnet (305) inside the accommodation groove (304) adsorb the needles inside the box body (202). S2. When the rotating cylinder (301) rotates, scrape the needles adsorbed on the surface of the suction plate (303) through the scraping plate (314) to avoid affecting the subsequent needle detection. S3. Finally, the transfer component moves the needle to a position above the material belt (404). At this time, the electromagnet (305) is powered off and loses its magnetic force, and the needle inside the receiving groove (304) will fall onto the material belt (404). The material belt (404) moves the needle to the bottom surface position of the detection board (101) to perform step-by-step detection work.
