Description

Technical Field

[0001] This utility model relates to the technical field of wire retraction braking devices, and in particular to an automatic wire retraction braking device. Background Technology

[0002] In the production process of solder strip, the process is generally as follows: oxygen-free copper wire - rolling - annealing - flux - tin plating - winding - packaging. In recent years, with the improvement of the automation level of solder strip equipment, the original manual brakes have been replaced by automatic brakes.

[0003] In the use of automatic braking devices, the brake discs are mostly fixed by bolts. When the brake discs are disassembled and replaced, multiple tools are required, which is quite troublesome and affects work efficiency.

[0004] Therefore, since most of the existing automatic braking devices use bolts to fix the brake discs, disassembling and replacing the brake discs requires multiple tools, which is cumbersome and affects work efficiency. Therefore, an automatic cable rewinding braking device can be designed. By rotating the knob, the knob, through the transmission disc and transmission rod, causes the fixing block to be inserted into the inner side of the fixing seat on the front face of the brake disc, so that the brake disc and the cable rewinding mechanism can be quickly disassembled and fixed. After the welding tape inside the cable rewinding mechanism is wound up, the pneumatic disc brake, in conjunction with the brake disc, brakes the cable rewinding mechanism. Utility Model Content

[0005] To overcome the problem that most existing automatic braking devices use bolts to fix the brake discs, which requires multiple tools to disassemble and replace the brake discs, making it cumbersome and affecting work efficiency.

[0006] The technical solution of this utility model is as follows: an automatic cable retraction braking device, including a cable retraction device, a cable retraction mechanism at the front end of the cable retraction device, a brake disc at the front of the cable retraction mechanism, a mounting seat at the center of the front end of the cable retraction mechanism behind the brake disc, the mounting seat extending through the brake disc to the outer side of the brake disc, a knob at the front end of the mounting seat, the bottom end of the knob extending to the inner side of the mounting seat, a transmission disc at the bottom end of the knob located inside the mounting seat, a transmission rod at the outer side of the transmission disc, a fixing block on one side of the transmission rod, a fixing seat at one end of the fixing block located on the outer end face of the brake disc, and a pneumatic disc brake on one side of the brake disc located on the outer end face of the cable retraction device.

[0007] Preferably, by rotating the knob, the knob, through the transmission disc and transmission rod, causes the fixing block to be inserted into the inner side of the fixing seat on the front face of the brake disc, so that the brake disc and the take-up mechanism can be quickly disassembled and fixed. After the welding strip inside the take-up mechanism is wound up, the pneumatic disc brake, in conjunction with the brake disc, performs a braking operation on the take-up mechanism.

[0008] Preferably, the take-up mechanism and the mounting base are integrated into one structure.

[0009] Preferably, one end of the mounting bracket has a through hole at the center of the brake disc, and the other end of the mounting bracket extends through the through hole to the outside of the brake disc.

[0010] Preferably, the knob and the drive disc are integrated into one structure.

[0011] Preferably, gears are provided at both the upper and lower ends of the transmission rod.

[0012] Preferably, one side of the transmission rod is provided with a toothed block on the outer side of the fixed block, and the transmission rod meshes with the transmission disc and the fixed block respectively through gears.

[0013] Preferably, one side of the transmission rod is provided with a toothed block on the outer side of the fixed block, and the transmission rod meshes with the transmission disc and the fixed block respectively through gears.

[0014] The beneficial effects of this utility model are:

[0015] This take-up brake device works by rotating a knob, which drives a transmission rod to rotate via a transmission disc. The transmission rod is connected to both the transmission disc and a fixed block via gears. When the transmission rod rotates, it causes the fixed block to move outward from the mounting base. One end of the fixed block is located on the front face of the brake disc and has a fixed seat. The fixed block is then inserted into the inside of the fixed seat to fix the brake disc to the take-up mechanism. When the detection mechanism detects that the welding strip inside the take-up mechanism has been wound up, the pneumatic disc brake, in conjunction with the brake disc, applies the brakes to the take-up mechanism.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4 This utility model provides a technical solution: an automatic cable retraction braking device, including a cable retraction device 1, a cable retraction mechanism 4 at the front end of the cable retraction device 1, a brake disc 2 in front of the cable retraction mechanism 4, and a mounting seat 5 at the center of the front end of the cable retraction mechanism 4 behind the brake disc 2. The mounting seat 5 extends through the brake disc 2 to the outer side of the brake disc 2. A knob 6 is provided at the front end of the mounting seat 5, and the bottom end of the knob 6 extends to the inner side of the mounting seat 5. A transmission disc 10 is provided at the bottom end of the knob 6 inside the mounting seat 5 for transmission. A transmission rod 11 is provided on the outer side of the disc 10. A fixing block 7 is provided on one side of the transmission rod 11. A fixing seat 8 is provided at one end of the fixing block 7 on the outer end face of the brake disc 2. A pneumatic disc brake 3 is provided on one side of the brake disc 2 on the outer end face of the take-up device 1. A detection mechanism 12 is provided at the top of the take-up mechanism 4. The detection mechanism 12 is electrically connected to the pneumatic disc brake 3. When the detection mechanism 12 detects that the welding strip inside the take-up mechanism 4 has been wound up, the pneumatic disc brake 3 cooperates with the brake disc 2 to brake the take-up mechanism 4.

[0023] Please see Figures 2-3 In this embodiment, the cable take-up mechanism 4 and the mounting base 5 are an integral structure. One end of the mounting base 5 is provided with a through hole at the center of the brake disc 2. The other end of the mounting base 5 extends through the through hole to the outside of the brake disc 2, thereby facilitating the connection between the cable take-up mechanism 4 and the brake disc 2 through the mounting base 5.

[0024] Please see Figures 3-4 The knob 6 and the transmission disc 10 are integrated. Gears are provided at both the upper and lower ends of the transmission rod 11. A toothed block 9 is provided on one side of the transmission rod 11 on the outer side of the fixing block 7. The transmission rod 11 meshes with the transmission disc 10 and the fixing block 7 through the gears. By rotating the knob 6, the knob 6 drives the transmission rod 11 to rotate through the transmission disc 10. The transmission rod 11 is connected to the transmission disc 10 and the fixing block 7 through the gears. When the transmission rod 11 rotates, it drives the fixing block 7 to move outward of the mounting base 5. A fixing seat 8 is provided at one end of the fixing block 7 on the front end face of the brake disc 2. The fixing block 7 is inserted into the inner side of the fixing seat 8 to fix the brake disc 2 and the cable take-up mechanism 4.

[0025] During operation, the brake disc 2 is first connected to the take-up mechanism 4. By rotating the knob 6, the knob 6 drives the transmission rod 11 to rotate through the transmission disc 10. The transmission rod 11 is connected to the transmission disc 10 and the fixing block 7 through gears. When the transmission rod 11 rotates, it drives the fixing block 7 to move outward towards the mounting base 5. One end of the fixing block 7 is located on the front end face of the brake disc 2 and has a fixing seat 8. The fixing block 7 is inserted into the inside of the fixing seat 8 to fix the brake disc 2 and the take-up mechanism 4. Then, the power is turned on and the device is started. The take-up mechanism 4 performs the take-up operation on the welding strip. When the detection mechanism 12 detects that the welding strip inside the take-up mechanism 4 has been taken up, the pneumatic disc brake 3 works in conjunction with the brake disc 2 to brake the take-up mechanism 4.

[0026] Through the above steps, by rotating knob 6, the knob 6, through transmission disc 10 and transmission rod 11, causes fixing block 7 to be inserted into the inner side of fixing seat 8 on the front end face of brake disc 2, so that brake disc 2 and cable take-up mechanism 4 can be quickly disassembled and fixed. After the welding strip inside the cable take-up mechanism 4 is wound up, the pneumatic disc brake 3, in conjunction with brake disc 2, performs braking operation on cable take-up mechanism 4. This solves the problem that most existing automatic braking devices use bolts to fix brake discs, which requires multiple tools when disassembling and replacing brake discs, making it cumbersome and affecting work efficiency.
