[0036] Working principle: In use, first connect the external power supply and switch to the electrical equipment in this device. When it is necessary to maintain and replace the brake pad 23, rotate the limiting plate 26 to drive the positioning rod 27 to rotate, compressing the torsion spring 29. After the limiting plate 26 rotates into the sliding groove 28 at the top of the rear surface of the positioning frame 22, the limiting plate 26 is in a vertical state. At this time, the brake pad 23 can be moved to slide the positioning block 24 out of the positioning groove 25, so that the brake pad 23 can be quickly removed. When installing a new brake pad 23, align the positioning groove 25 on the brake pad 23 with the positioning block 24 on the right side of the mounting plate 21. Since both the positioning block 24 and the positioning groove 25 are designed with... When the positioning groove 25 is shaped like a T, and the positioning groove 25 slides tightly against the outer wall of the positioning block 24, the direction of movement of the brake pad 23 to the right is limited. At the same time, the opening behind the positioning groove 25 restricts the movement distance of the positioning block 24 after insertion, thus initially fixing the position of the brake pad 23. Subsequently, when the limiting plate 26 is released, the reverse force generated by the compression of the torsion spring 29 quickly drives the limiting plate 26 to reset, tightly adhering to the front surface of the brake pad 23, thereby firmly limiting the brake pad 23. The brake pad 23 can be installed and replaced quickly without the need for complicated bolt disassembly and reinstallation. The operation is simple and quick, improving maintenance and replacement efficiency.

[0037] When the machine body 1 receives the anti-rotation signal, the cylinder 4 connected to the signal starts to work. The cylinder 4 pushes the mounting plate 21 fixedly connected to it. The mounting plate 21 drives the brake pad 23 on the right side to move to the right. During the movement of the mounting plate 21 to the right, the top of the connecting rod 31 hinged to the bottom of the mounting plate 21 is pushed, causing the connecting rod 31 to rotate downward around the hinge point and push the guide plate 33 downward. The bottom of the guide plate 33 is fixedly connected to the bottom of the inner wall of the machine body 1 through the telescopic rod 3. The telescopic rod 3 supports the guide plate 33 and restricts it to move only up and down. As the guide plate 33 moves downward, it drives the lower part of another set of connected rods 31 to move downward, thereby pulling another set of connected rods 31 to move downward. The upper part of the connecting rod 31 and the other set of mounting plates 21 are restricted to moving only left and right by the telescopic rod 32. Therefore, under the action of tension, the other set of mounting plates 21 moves to the left, which at the same time drives the other set of brake pads 23 to move to the left. Through this left-right symmetrical structure, the two sets of brake pads 23 can simultaneously press against the turntable 2. The two sets of brake pads 23 act on the turntable 2 at the same time, which greatly increases the friction area and the pressing effect. In a short time, a strong friction force is generated, which effectively prevents the turntable 2 from rotating and achieves the purpose of quickly limiting the turntable 2. This ensures the rapid response of the braking action, improves the stability and reliability of the brake, and meets the braking and anti-rotation requirements of the spinning machine during operation.
