[0035] Working principle: When the device is in use, the staff can disassemble the connection between the needle cylinder body 2 and the knitting circular machine housing 1, and after disassembly, maintain the needle cylinder body 2. After the needle cylinder body 2 has been maintained, the needle cylinder body 2 can be replaced on the top of the knitting circular machine housing 1, and after placement, the bottom plate 301 can be placed on the inner side of the knitting circular machine housing 1, and at the same time, one of the output shafts of the dual-axis servo motor 305 is started. Through the operation of the dual-axis servo motor 305, the gear 3021 is driven to rotate, and through the rotation of the gear 3021, the two racks 3022 are driven to move in opposite directions. After moving to a certain distance, it can be supported inside the knitting circular machine housing 1, and at this time, the bottom plate 301 is smoothly and stably connected to the inner side of the needle cylinder body 2 through the support block 3023. At this time, the staff can start the other output shaft of the dual-axis servo motor 305, and through the rotation of the other output end, the drive rod 306 is driven to drive the rotating block 307 to rotate. During the rotation process, the rotating block 307 In the process, the slider 310 will be pushed by the pushing plate 308, so that the slider 310 slides along the top of the mounting plate 304. After the slider 310 slides to a certain distance, the rubber fixing block 312 can be used to push the needle cylinder body 2 to fix the needle cylinder body 2. After that, the staff can measure whether the position of the needle cylinder body 2 meets the required position. If the position of the needle cylinder body 2 does not meet the required position, the micro servo motor 3094 can be started. The operation of the micro servo motor 3094 drives the screw 3092 to rotate, and drives the moving block 3093 to drive the pushing ring block 3095 to move, thereby achieving a slight and fine adjustment of the position of the needle cylinder body 2. After the needle cylinder body 2 is adjusted to the appropriate position, the auxiliary mechanism 3 can be set, and the pushing ring block 3095 and the rubber fixing block 312 can be used to fix the inner support of the needle cylinder body 2, and the locking bolt can be connected to the inside of the knitting machine housing 1 and the needle cylinder body 2 to achieve the auxiliary function of installing the needle cylinder body 2 after maintenance.
