[0018] The technical scheme in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] Please refer to Figure 1 And Figure 2The utility model provides a needle selection device of circular knitting towel machine, including the casing 1, magnetic control main body 2 and a plurality of needle selection piece 3, magnetic control main body 2 is arranged in the casing 1, the front side of casing 1 is provided with a plurality of movable slots 102 with a plurality of needle selection piece 3 one-to-one correspondence, needle selection piece 3 is rotatably connected with the pivot 4, needle selection piece 3 is rotatably connected in the corresponding movable slot 102 through the pivot 4, the inner end of needle selection piece 3 is magnetically connected with magnetic control main body 2, and the outer end of needle selection piece 3 is exposed outside the casing 1, and the left and right sides of movable slot 102 are provided with the insertion slot 103 matched with the pivot 4, and the insertion block 5 for limiting the rotation of the pivot 4 is slidably connected on the insertion slot 103.

[0020] Please refer to Figure 5 , the pivot 4 includes two detachably connected cylinders 401, and the two cylinders 401 are provided with limiting rings 402, the limiting rings 402 are used to limit the axial displacement of the needle selection piece 3, and ensure that the needle selection piece 3 stably rotates on the pivot 4.

[0021] Please refer to Figure 2 、 Figure 4 and Figure 5 , the two cylinders 401 are provided with two positioning columns 403, the insertion slot 103 of the casing 1 is provided with a positioning slot 104 matched with the positioning column 403, and the bottom of the insertion block 5 is matched with the two cylinders 401 and the positioning column 403 thereon, when the pivot 4 is located in the insertion slot 103, and the insertion block 5 is also inserted into the insertion slot 103, the two cylinders 401 are limited to rotate under the cooperation of the positioning column 403, the insertion block 5 and the positioning slot 104, further ensuring that the needle selection piece 3 stably rotates on the pivot 4.

[0022] Please refer to Figure 1 and Figure 3 , the front part of the casing 1 is detachably connected with the fixed plate 6, and the top of all insertion blocks 5 is connected to the bottom of the fixed plate 6, so that all insertion blocks 5 can be operated synchronously through the fixed plate 6.

[0023] Please refer to Figure 1 and Figure 3 , the opening of the casing 1 is provided with a closure 7, and the two ends of the closure 7 are rotatably connected with the fixed plate 6 and the casing 1 respectively, and the closure 7 is used for protecting the internal structure of the needle selection device.

[0024] Please refer to Figure 1 , the left and right sides of the casing 1 are provided with a plurality of heat dissipation holes 105.

[0025] Working principle: in use, the magnetic control body 2 generates a corresponding electromagnetic field according to the preset knitting instructions, and acts on the inner end of the specific needle selection piece 3, so that the needle selection piece 3 rotates around the rotating shaft 4 to the predetermined position. At the same time, the unselected needle selection piece 3 remains in place due to the lack of magnetic force. With the rotation of the needle selection piece 3, the knitting needle of the knitting machine performs corresponding knitting action according to the position of the needle selection piece 3. This process is carried out one by one under the continuous control of the magnetic control body 2 according to the preset knitting pattern, until the entire knitting cycle is completed. In the entire working process, the heat generated by the magnetic control body 2 is continuously discharged through the heat dissipation hole 105 of the shell 1, ensuring that the device can work stably for a long time.

[0026] When part of the needle selection piece 3 needs to be replaced due to long-term use or accidental damage, first, the fixed plate 6 is disassembled, then all the insertion blocks 5 are slid upward together out of the insertion slot 103 through the fixed plate 6, and then the closed cover 7 is rotated open. Subsequently, the damaged needle selection piece 3 is slid upward out of the insertion slot 103, and the positioning column 403 on the rotating shaft 4 of the new needle selection piece 3 is aligned with the positioning groove 104. Then, the needle selection piece 3 is slid downward and installed, and then the fixed plate 6 is reinstalled to ensure that the insertion block 5 is correctly returned to its original position and the rotating shaft 4 is locked. Finally, the closed cover 7 is closed, completing the replacement and maintenance of the damaged needle selection piece 3. In this way, for the partially damaged needle selection piece 3, it can be quickly replaced by simply plugging and unplugging without the need to disassemble the remaining intact needle selection pieces 3.
