With the development of technology, the driving method of the jacquard machine is also gradually improving. At present, high-speed magnetic levitation driven jacquard knitting needle circular knitting machine has appeared. Its advantages are that the magnetic levitation strong needle movement is contactless, frictionless, high efficiency, fast needle response speed, and high needle selection frequency.

The knitting needles are driven by the connecting rod device to perform upper, middle and lower three-station movements, which effectively solves the problem of too small gaps between the outer cylinders of adjacent magnetic suspension drive devices. The principle of mechanical levers can be used to change the force application points at the same time, eliminate the shortcomings caused by the bending torque of the knitting needles, and optimize the load form of the magnetic suspension drive device.

[0023] It should be noted that the top of the thimble 10 is connected to the structure such as the needle plate of the double-layer magnetic suspension device connecting rod driving the knitting needle jacquard circular knitting machine, which is a mature and public technology in the prior art. Therefore, the working principle of the thimble 10 driving the jacquard machine to weave is not repeated in this article. In addition, the coil part 5 control circuit can be realized by simple programming by technicians in this field, and the provision of power is also common knowledge in this field. This application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.

[0024] See also Figure 1-3The fixing mechanism includes eight clamping plates 601 respectively connected to the opposite sides of the first mounting block 2 and the second mounting block 4 in a sliding manner. Four rectangular grooves 602 are provided on the opposite sides of the first mounting block 2 and the second mounting block 4. A guide rod 603 is fixed between the inner walls of the rectangular grooves 602 and horizontally penetrates the clamping plate 601 and is slidably connected thereto. A spring 604 is sleeved on the outer peripheral wall of the guide rod 603. A limiting block 605 is fixed on the side of the clamping plate 601 facing the coil member 5. The back of the clamping plate 601 is fixed with a limit block 605. A roller 606 is rotatably connected to one side of the limit block 605. The eight clamping plates 601 are evenly divided into two groups and are distributed up and down. The guide rod 603 is a square rod. A square guide hole for the guide rod 603 to pass through is provided on the side of the clamping plate 601 facing the coil member 5. The spring 604 is located on the side of the clamping plate 601 facing the coil member 5. The four clamping plates 601 on the first mounting block 2 and the second mounting block 4 are all distributed in a circle with equal angles along the central axis of the outer cylinder 3. When the coil member 5 is damaged, When maintenance is required, the threaded cylinder 9 is rotated to disengage the connecting rod 8 from the ejector pin 10, and then the outer cylinder 3 is rotated to disengage it from the first mounting block 2. When the outer cylinder 3 is disengaged from the first mounting block 2, the roller 606 on the first mounting block 2 no longer abuts against the inner wall of the outer cylinder 3. At this time, the spring 604 pushes the clamping plate 601 to slide along the guide rod 603 to the side away from the coil member 5, thereby driving the limit block 605 to disengage from the top surface of the coil member 5, so that the coil member 5 can be easily taken out for replacement, and then the second The mounting block 4 slides downward, and when the guide block 11 slides to the bottom of the guide groove 12, the bottom end of the clamping plate 601 on the second mounting block 4 just extends to the bottom of the outer cylinder 3 so that the roller 606 does not abut against the inner wall of the outer cylinder 3, and the top coil part 5 can be disassembled. When the inspection is completed, the coil part 5 is placed between the four clamping plates 601, and then put into the outer cylinder 3. The inner wall of the outer cylinder 3 cooperates with the four rollers 606 to squeeze the clamping plate 601 for relative movement to clamp and limit.

[0025] See also Figure 4 Two guide blocks 11 are fixed on the outer wall of the second mounting block 4, and two guide grooves 12 for sliding connection of the guide blocks 11 are provided on the inner wall of the outer cylinder 3. When the second mounting block 4 slides up and down, the guide grooves 12 cooperate with the guide blocks 11 to facilitate improving the stability of the second mounting block 4 sliding up and down.

[0026] The outer cylinder 3 is a circular cylinder with a hollow interior and an open bottom. The bottom surface of the guide groove 12 is higher than the top surface of the lower coil member 5. The first mounting block 2 and the second mounting block 4 are both circular blocks and face each other vertically.

[0027] The working principle of the above embodiment is:

[0028] When in use, a set regular current is provided to the two coil members 5 to generate magnetic force, so that the top coil member 5 is suspended inside the outer cylinder 3 and drives the second mounting block 4 to cooperate with the guide block 11 and the guide groove 12 to slide up and down. The second mounting block 4 drives the connecting rod 8 and the ejector pin 10 to reciprocate up and down, thereby driving the jacquard machine to work. When the coil member 5 is damaged and needs to be repaired, the threaded cylinder 9 is rotated to disengage the connecting rod 8 and the ejector pin 10, and then the outer cylinder 3 is rotated to disengage it from the first mounting block 2. When the outer cylinder 3 is disengaged from the first mounting block 2, the roller 606 on the first mounting block 2 no longer abuts against the inner wall of the outer cylinder 3. At this time, the spring 604 pushes the clamping plate 601 along the guide groove 12. The rod 603 slides to the side away from the coil component 5, thereby driving the limit block 605 to separate from the top surface of the coil component 5, so that the coil component 5 can be easily taken out for replacement, and then the second mounting block 4 slides downward. When the guide block 11 slides to the bottom of the guide groove 12, the bottom end of the clamping plate 601 on the second mounting block 4 just extends to the bottom of the outer cylinder 3 so that the roller 606 does not abut against the inner wall of the outer cylinder 3, and the top coil component 5 can be disassembled. When the inspection is completed, the coil component 5 is placed between the four clamping plates 601, and then put into the outer cylinder 3. The inner wall of the outer cylinder 3 cooperates with the four rollers 606 to squeeze the clamping plate 601 for relative movement to clamp and limit.
