[0002] During the production process of spring steel wires, a wire pay-off stand is a device used to protect the steel wires or cables from external friction and extrusion, prevent damage, make the organization of the steel wires or cables more orderly, and facilitate winding, unwinding and transportation. The wire pay-off stand pays off wires by rotating. When paying off wires, a braking device is usually required to avoid emergencies. For example, when the equipment fails or needs to be stopped urgently, the braking device can respond quickly. Currently, most of them use automatic braking devices. However, the automatic braking system cannot accurately adjust the braking force when needed, resulting in the wire being paid off too fast or too slow, thus causing problems such as wire knotting or breaking, and it cannot effectively identify and handle all types of faults, such as wire breakage or equipment abnormalities, which leads to production interruption or product quality decline. Summary of the Invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a wire pay-off stand braking device, which can effectively solve the problems that the automatic braking system cannot accurately adjust the braking force when needed, resulting in the wire being paid off too fast or too slow, thus causing problems such as wire knotting or breaking, and it cannot effectively identify and handle all types of faults, such as wire breakage or equipment abnormalities, which leads to production interruption or product quality decline.

A strip-shaped hole is opened on the smooth surface of the screw rod, and the screw rod is limited on the vertical plate by a limiting rod passing through the strip-shaped hole. The threaded end of the screw rod is connected with a nut and is located on the right side of the vertical plate. A spring is sleeved on the screw rod between the right side wall of the vertical plate and the nut. One end of the screw rod located on the left side of the vertical plate is connected with a brake band. The other end of the brake band bypasses the rotating cylinder under the bearing plate and is connected with a vertical rod, and the vertical rod is fixedly connected to the right end of the top surface of the second top rod.

[0005] The structure of the utility model is simple. Only by tightening the nut in the brake mechanism, under the elastic force of the spring, the screw rod can generate a tensile force. Under the fixing action of the vertical rod at the other end, the brake belt is pulled to tighten the brake belt. By increasing the friction force between the brake belt and the contact surface of the rotating cylinder, the braking is realized. The utility model is a manual brake, which can cope with all types of failures. And the braking force can be adjusted accordingly as needed, avoiding the problems of wire knotting or breaking. It is convenient and fast to operate and has good economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0010] The following further describes the utility model in conjunction with the drawings and the detailed description of the embodiments:

[0011] As Figures 1 - 3 shown, a wire reel braking device includes a base 1. A rotating cylinder 2 is rotatably connected to the top surface of the base 1. A bearing plate 3 is sleeved on the lower part of the outer wall of the rotating cylinder 2. The bearing plate 3 is circular. A first ejector rod 4 and a second ejector rod 5 are fixedly connected to the front and rear parts of the bottom surface of the base 1. Both the first ejector rod 4 and the second ejector rod 5 are long strip-shaped rods. The right ends of the first ejector rod 4 and the second ejector rod 5 are both located on the right side of the base 1. A brake mechanism is provided on the top surface of the first ejector rod 4 located on the right side of the base 1.

[0012] The braking mechanism includes a vertical plate 6, which is fixed to the right end top surface of the first ejector rod 4. The vertical plate 6 is a rectangular plate, and a screw rod 7 is movably penetrated through the vertical plate 6. One end of the screw rod 7 is smooth, and the other end is provided with a thread on its peripheral wall. A strip-shaped hole 8 is opened on the smooth surface of the screw rod 7. The strip-shaped hole 8 is a long strip-shaped hole opened along the length direction of the screw rod 7. The upper and lower ends of the strip-shaped hole 8 respectively penetrate through the top surface and the bottom surface of the screw rod 7. The screw rod 7 is limited on the vertical plate 6 by a limiting rod 9 passing through the strip-shaped hole 8. The threaded end of the screw rod 7 is connected with a nut 10 and is located on the right side of the vertical plate 6. A spring 11 is sleeved on the screw rod 7 between the right side wall of the vertical plate 6 and the nut 10. One end of the screw rod 7 on the left side of the vertical plate 6 is connected with a brake belt 12. The other end of the brake belt 12 bypasses the rotating cylinder 2 under the bearing plate 3 and is then connected with a vertical rod 13. The vertical rod 13 is fixedly connected to the right end top surface of the second ejector rod 5.

[0013] The vertical plate 6 is vertically fixed on the first ejector rod 4, and the vertical rod 13 is vertically fixed on the second ejector rod 5. A straight hole 14 is opened on the outer wall of one end of the screw rod 7 on the left side of the vertical plate 6. The straight hole 14 penetrates through the screw rod 7 from front to back. A circular ring 15 is fixedly connected to the side wall surface of the vertical rod 13 facing the rotating cylinder 2.

[0014] One end of the brake belt 12 is connected to the screw rod 7 through a first steel wire rope 16 via the straight hole 14, and the other end is connected to the vertical rod 13 through a second steel wire rope 17 via the circular ring 15.

[0015] The brake belt 12 is a strip-shaped body woven from polyester material.

[0016] A through hole 19 for the screw rod 7 to movably pass through is provided on the vertical plate. A limiting rod 9 is provided on the top surface of the vertical plate 6. The lower end of the limiting rod 9 penetrates downward from the top surface of the vertical plate 6 through the strip-shaped hole 8 and extends into the vertical plate 6 below the through hole 19. When the nut 10 is rotated, the screw rod 7 can move horizontally along the strip-shaped hole 8 under the action of the limiting rod 9.

[0017] Reinforcing plates 18 are provided at the front and rear of the top surface of the first ejector rod 4. Both of the two reinforcing plates 18 are right-angled triangles. One straight side of the reinforcing plate 18 is connected to the first ejector rod 4, and the other straight side is connected to the vertical plate 6. The screw rod 7 is located between the two reinforcing plates.

[0018] During use, the steel wire rod is wound and sleeved around the outer periphery of the rotating cylinder 2 and is located on the bearing plate 3. When a failure occurs and the wire pay-off operation of the pay-off frame needs to be stopped, the operator tightens the nut 10 to make the nut 10 approach the vertical plate 6, squeezing the spring 11. Under the combined action of the spring 11 and the nut 10, the screw rod 7 is pushed to move to the right. Under the limitation of the limiting rod 9, the screw rod 7 moves along the length direction of the strip-shaped hole 8. When the screw rod 7 moves to the right, the brake band 12 will be pulled. Under the fixing action of the vertical rod 13 connected to the other end of the brake band 12, the brake band 12 is tightened, increasing the friction with the rotating cylinder 2, causing the rotating cylinder 2 to stop rotating and completing the braking. By adjusting the nut 10, the braking force can also be adjusted accordingly as needed.
