[0025] Please refer to Figure 1-4A braking mechanism for an unwinding machine includes a support seat 1 and a brake disc 5. A support frame 2 is welded onto the support seat 1, and a bracket 3 is fixedly installed on the support frame 2. A brake seat 4 is installed on the bracket 3, and a brake pad 9 is installed inside the brake seat 4. A hydraulic cylinder 7 is installed on the bracket 3, and the telescopic end of the hydraulic cylinder 7 is connected to the brake pad 9. A locking block 11 is installed on the telescopic end of the hydraulic cylinder 7. A connecting seat 10 is fixedly installed on one side surface of the brake pad 9, and a locking groove 12 is opened on the side surface of the connecting seat 10 away from the brake pad 9. The locking block 11 engages with the locking groove 12. Positioning holes 13 are opened on the surfaces of the connecting seat 10 and the locking block 11, and a positioning rod 14 is inserted through the positioning hole 13. A pull ring 15 is installed on one end of the positioning rod 14, and a spring 16 is sleeved on the outside of the positioning rod 14 between the pull ring 15 and the connecting seat 10. A storage groove 8 is opened on the surface of the brake seat 4, and the brake pad 9 is used in conjunction with the storage groove 8.
[0026] In use, by setting up easily removable brake pads 9, pulling the pull ring 15 moves the positioning rod 14 out of the positioning hole 13, and then moving the brake pads 9 horizontally, the brake pads 9 can be removed, achieving the effect of convenient disassembly and replacement of brake pads 9. Maintenance and replacement of brake pads 9 are more time-saving and labor-saving, with strong practicality and worth promoting.

[0027] In this embodiment: the surface of the brake disc 5 is provided with ventilation holes 6, and there are multiple ventilation holes 6.
[0028] Specifically, while providing ventilation and heat dissipation, it also improves braking efficiency and suppresses braking noise.

[0029] In this embodiment, multiple brake pads 9 are provided, and the multiple brake pads 9 are arranged in a ring array on both sides of the brake disc 5.
[0030] Specifically, increasing the friction between the brake disc 5 and the brake rotor results in better braking performance.
[0031] In this implementation plan, the number of hydraulic cylinders 7 is the same as the number of brake pads 9.
[0032] Specifically, this allows multiple hydraulic cylinders 7 to drive the brake pads 9 one-to-one.
[0033] In this embodiment: multiple ventilation holes 6 are arranged in a ring array on the surface of the brake disc 5.
[0034] Specifically, further improve braking performance.
[0035] In this implementation scheme: the depth of the ventilation hole 6 is the same as the thickness of the brake disc 5.
[0036] Specifically, it improves ventilation and heat dissipation efficiency.
[0037] Working principle: In use, by setting up easily removable brake pads 9, pulling the pull ring 15, the pull ring 15 moves and causes the positioning rod 14 to move out of the positioning hole 13. Then, by moving the brake pads 9 horizontally, the brake pads 9 can be removed, achieving the effect of convenient disassembly and replacement of brake pads 9. Maintenance and replacement of brake pads 9 are more time-saving and labor-saving, with strong practicality and worth promoting. In addition, by setting up ventilation holes 6, ventilation and heat dissipation can be accelerated, while improving braking efficiency and suppressing braking noise. Furthermore, it can also reduce weight, balance pressure, and disperse braking force and temperature, achieving multiple benefits and strong practicality, which is worth promoting.
