Moreover, the traditional machine does not have a wire break detection mechanism. When a wire break occurs, it will not give an early warning and continue to work, which will lead to unqualified product quality. The broken steel wire may also wind inside the machine, causing blockage to the machine and damaging the machine. In severe cases, the production line may be paralyzed. Summary of the Utility Model
[0004] Aiming at the above-mentioned disadvantages of the prior art, the utility model provides a forming defect detection device applicable to an internal take-up stranding machine, which can effectively solve the problem of the lack of wire break detection in the prior art.
[0005] To achieve the above object, the utility model is realized through the following technical solutions:
[0006] The utility model provides a forming defect detection device applicable to an internal take-up stranding machine, including a base. On both sides of the top of the base, a support plate and a rope stranding seat are respectively fixedly installed. On one side of the support plate close to the rope stranding seat, a wire pay-off frame is rotatably connected, and on the other side, a motor for driving the wire pay-off frame to rotate is fixedly installed. Inside the wire pay-off frame, a plurality of wire pay-off components are arranged. On one side of the wire pay-off frame, a wire pay-off groove corresponding to the wire pay-off component is opened.

[0007] The detection component includes a fixing ring fixedly installed on the inner wall of the wire pay-off hole. On the inner wall of the fixing ring, a plurality of grooves are circularly arranged. On the inner wall of each groove and on one side far from the axis of the fixing ring, a first spring is fixedly installed, and the other end of the first spring is fixedly installed with a resisting rod. The other end of the resisting rod contacts the outer surface of the steel wire rope. On the inner wall of one of the grooves and on one side close to the axis of the fixing ring, a pressure sensor is fixedly installed. The pressure sensor is electrically connected to the motor and the rope stranding seat through a control system.
[0008] According to the above-mentioned forming defect detection device applicable to an internal take-up wire stranding machine, the wire pay-off assembly includes a wire pay-off roller rotatably connected inside a wire pay-off frame. Two baffles are symmetrically and fixedly installed on the outer side of the wire pay-off roller, and the steel wire rope is placed between the two baffles.

Specific embodiments
[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0021] The present utility model will be further described below with reference to the embodiments.
[0022] Embodiment: Refer to Figures 1 to 3 , a forming defect detection device applicable to an internal take-up wire twisting machine, comprising a base 1, support plates 2 and a rope twisting seat 21 are respectively and fixedly installed on both sides of the top of the base 1, a wire pay-off frame 3 is rotatably connected to one side of the support plate 2 close to the rope twisting seat 21, and a motor 31 for driving the wire pay-off frame 3 to rotate is fixedly installed on the other side. A plurality of wire pay-off components are arranged inside the wire pay-off frame 3, a wire pay-off groove corresponding to the wire pay-off components is formed on one side of the wire pay-off frame 3, a rotating shaft 32 is fixedly installed on one side of the wire pay-off frame 3, and a fixing plate 33 is fixedly installed on the outer side of the rotating shaft 32. A plurality of wire pay-off holes are formed inside the fixing plate 33, and a detection component is arranged inside each wire pay-off hole;
[0023] The detection component includes a fixing ring 4 fixedly installed on the inner wall of the wire pay-off hole. A plurality of grooves 41 are arranged in a circular array on the inner wall of the fixing ring 4. On the inner wall of each groove 41 and on one side away from the axis of the fixing ring 4, a first spring 42 is fixedly installed, and the other end of the first spring 42 is fixedly installed with a pressing rod 43. The other end of the pressing rod 43 contacts the outer surface of the wire rope. On the inner wall of one of the grooves 41 and on one side close to the axis of the fixing ring 4, a pressure sensor 44 is fixedly installed. The pressure sensor 44 is electrically connected to the motor 31 and the wire twisting seat 21 through a control system. During use, the wire rope is passed through the fixing ring 4, and the pressing rod 43 is squeezed by the wire rope to move it toward the mutually separated sides, so that the pressing rod 43 does not contact the pressure sensor 44, and at this time the first spring 42 is in a compressed state. When the wire rope is broken, the pressing rod 43 is pushed toward the mutually approaching sides by the resilience of the first spring 42, and the pressing rod 43 contacts the pressure sensor 44 during the rising process. At this time, the pressure sensor 44 is squeezed and receives a signal, and the motor 31 and the wire twisting seat 21 are controlled to pause operation through the control system.
[0024] The wire pay-off component includes a wire pay-off roller 5 rotatably connected inside the wire pay-off frame 3. Two baffles 51 are symmetrically and fixedly installed on the outer side of the wire pay-off roller 5. The wire rope is placed between the two baffles 51. The wire rope on the outer side of the wire pay-off roller 5 can be limited by the baffles 51, improving the use effect of the device.
[0025] Two fixing grooves 6 are symmetrically opened inside the wire pay-off frame 3 at both ends of the wire pay-off roller 5. On the inner wall of each fixing groove 6 and on one side away from the wire pay-off roller 5, a second spring 61 is fixedly installed, and the other end of the second spring 61 is fixedly installed with a fixing block 62. The fixing block 62 is in a one-to-one limit sliding connection with the fixing groove 6, and the bottom of the fixing block 62 contacts the outer surface of the wire pay-off roller 5. The two fixing blocks 62 are pushed toward the mutually approaching sides by the elasticity of the second spring 61, so that the wire pay-off roller 5 can be fixed, preventing the wire pay-off roller 5 from falling during use, and at the same time facilitating the installation or disassembly of the wire pay-off component.
[0026] A first wire passing wheel 7 is rotatably connected inside each wire pay-off groove. The opposite sides of the two first wire passing wheels 7 both contact the outer surface of the wire rope, preventing the wire rope from directly contacting the wire pay-off frame 3 and causing wear.
[0027] Brackets 8 are staggeredly and fixedly installed on the outer wall of the fixing plate 33 on both sides of the wire pay-off hole. A second wire passing wheel 81 is rotatably connected inside each bracket 8, preventing the wire rope from directly contacting the fixing plate 33 and causing wear, and at the same time ensuring that the wire rope remains horizontal when passing through the wire pay-off hole, facilitating the detection component inside to detect the wire rope.
[0028] A warning light 9 is fixedly installed on the top of the fixing plate 33. The warning light 9 is electrically connected to each pressure sensor 44. When working normally, the warning light 9 emits green light. When a wire break occurs, the abutting rod 43 moves upward through the elastic force of the first spring 42 to contact the pressure sensor 44. By using the electrical connection between the pressure sensor 44 and the warning light 9, at this time, the warning light 9 emits red light and flashes continuously, alerting the staff.
[0029] The working principle of the present utility model is as follows: When in use, one end of the steel wire rope on the wire pay-off reel 5 passes through the wire pay-off groove and the wire pay-off hole. At the same time, the steel wire rope passes through the first wire guiding wheel 7, the fixing ring 4, and the second wire guiding wheel 81 in sequence on the way. By using the first wire guiding wheel 7 and the second wire guiding wheel 81, it can prevent the steel wire rope from being damaged due to friction when passing through the wire pay-off frame 3 and the fixing plate 33. When the steel wire rope passes through the fixing ring 4, it will squeeze the multiple abutting rods 43 inside it, causing them to move towards the other end of the first spring 42, and the abutting rod 43 no longer contacts the pressure sensor 44. At this time, the warning light 9 on the top of the fixing plate 33 also continuously emits green light, indicating that the device is working normally. Finally, the other end of the steel wire rope is fixed on the rope twisting seat 21, and then the motor 31 is started. The wire pay-off frame 3 is driven to rotate by the motor 31, so as to twist the steel wire rope fixed on the rope twisting seat 21. When a wire break occurs at a certain place of the steel wire, at this time, the steel wire rope no longer squeezes the abutting rod 43. The abutting rod 43 is pushed back to its original position by the resilience of the first spring 42. After one of the abutting rods 43 is reset, it will contact the pressure sensor 44, causing a change in the pressure of the pressure sensor 44. By using the fact that the pressure sensor 44 is electrically connected to the rope twisting seat 21, the motor 31, and the warning light 9 through the control system, at this time, the motor 31 and the rope twisting seat 21 stop running, and the warning light 9 flashes continuously and emits red light to warn the staff, ensuring that the staff can detect it in time and improving the use effect of the device.
[0030] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
