Description

Technical Field

[0001] This application relates to the field of winding equipment technology, and in particular to a winding machine with a wire breakage self-detection device. Background Technology

[0002] A winding machine is a mechanical device used to wind metal wires onto various coil frames, iron cores or other workpieces according to specific requirements. Existing winding machines typically include a pay-off roller, a take-up roller and multiple guide rollers. The metal wire on the pay-off roller is wound onto the take-up frame of the take-up roller by the rotation of the take-up roller.

[0003] However, in the actual winding process, the metal wire needs to withstand a certain tension in the conveying path and will come into contact with the guide rollers through friction. During this process, the metal wire is very prone to breakage due to factors such as excessive instantaneous tension, accelerated local wear, material defects, or improper joint treatment.

[0004] If a metal wire breaks and cannot be detected and stopped in time, the free end of the broken wire will become tangled on the guide roller or take-up frame as the equipment runs, forming a messy clump of wire. This requires workers to spend a lot of time cleaning it up, which reduces the winding efficiency of the metal wire and has obvious shortcomings. Utility Model Content

[0005] In order to enable timely detection of broken metal wires and improve winding efficiency, this application provides a winding machine with a wire breakage self-inspection device.

[0006] The winding machine with a self-detection device for wire breakage provided in this application adopts the following technical solution: A winding machine with a wire breakage self-detection device includes a worktable, on which a pay-off roller and a take-up roller are arranged. A detection plate is arranged on the worktable via a support assembly. The detection plate is positioned above the pay-off roller. A wire breakage detection sensor is arranged on the detection plate. A metal wire passes through the wire breakage detection sensor. The wire breakage detection sensor is electrically connected to an alarm element via a control system.

[0007] By adopting the above technical solution, when the metal wire breaks, the wire breakage detection sensor detects the broken state of the metal wire and transmits the information to the control system, triggering the alarm to remind the operator to shut down the winding machine in time. This reduces the possibility that the broken wire will not be detected in time and will cause a large number of broken wires to entangle and form clumps as the equipment runs, reducing the time workers spend cleaning up the clumps and thus improving the winding efficiency of the metal wire.

[0008] Optionally, the support assembly includes a column mounted on the workbench, a support frame mounted on the column, and the detection plate being detachably connected to the support frame by bolt clamps.

[0009] By adopting the above technical solution, when the wire breakage detection sensor needs to be replaced due to failure, workers can disassemble and maintain the entire detection board by adjusting the tightness of the bolt clamps, thereby ensuring the detection component's function of detecting wire breakage.

[0010] Optionally, the support frame is provided with a tension compensation component, which includes a fixed frame mounted on the support frame, a tension arm rotatably connected to the fixed frame, an end of the tension arm extending out of the fixed frame and rotatably mounted with a tension wheel, a metal wire abutting against the tension wheel, a compensation spring mounted on the fixed frame, and a compensation spring having one end away from the fixed frame mounted on the tension arm. The compensation spring changes the tension on the tension arm through its extension and contraction deformation to dynamically compensate for changes in the tension of the metal wire.

[0011] By adopting the above technical solution, the metal wire passes through the wire breakage detection sensor and is wound around the tensioning wheel. When the tension of the metal wire increases, the additional tension acts on the tensioning wheel, driving the tension arm to rotate. The tension arm lengthens the compensating spring, and the elastic force of the compensating spring increases, thereby offsetting part of the additional tension and reducing the risk of the metal wire breaking due to a sudden increase in tension. When the tension of the metal wire decreases, the elastic force of the compensating spring is greater than the force exerted by the metal wire on the tensioning wheel. The compensating spring pulls the tension arm to rotate in the opposite direction, and the tension arm drives the transition wheel to tighten the metal wire, thereby increasing the tension of the metal wire and reducing the slack of the metal wire. In this way, the metal wire maintains a stable tension during the winding process, reducing the risk of metal wire breakage caused by tension fluctuations.

[0012] Optionally, the fixing frame is provided with a guide frame, and the tension arm is slidably connected inside the guide frame.

[0013] By adopting the above technical solution, the guide frame limits the movement path of the tension arm, preventing the tension arm from rotating excessively and causing the compensation spring to exceed its elastic limit or the metal wire to be stretched excessively, thereby improving the reliability of the tension compensation component.

[0014] Optionally, the support frame can be slidably sleeved on the outer surface of the column along the axis of the column. The support frame is fixed to the column by a first locking bolt. A connecting seat is slidably passed through the support frame. A pin is rotatably connected inside the connecting seat. The fixing frame can be rotatably sleeved on the outer surface of the pin around the axis of the pin. The connecting seat is fixed to the support frame by a second locking bolt. The fixing frame is fixed to the outer surface of the pin by a third locking bolt.

[0015] By adopting the above technical solution, workers can adjust the height of the support frame on the column by adjusting the tightness of the first locking bolt, adjust the horizontal position of the fixing frame on the support frame by adjusting the tightness of the second locking bolt, and adjust the angle of the fixing frame by adjusting the tightness of the third locking bolt. In this way, multi-dimensional adjustment of the tension compensation component can be achieved, so that the position and angle of the tension compensation component can be adapted to the needs of different winding paths of metal wire, thus improving the applicability of the winding machine.

[0016] Optionally, a transition assembly is provided on the workbench, the transition assembly is disposed between the pay-off roller and the take-up roller, the transition assembly includes a transition roller disposed on the workbench, a support block is sleeved on the transition roller, a first transition frame is detachably connected to the support block by bolt clamps, a second transition frame is detachably connected to the end of the first transition frame near the take-up roller by bolts, and a transition wheel is rotatably connected to the first transition frame and the second transition frame.

[0017] By adopting the above technical solution, the metal wire passes through multiple transition wheels in sequence after passing through the tensioning wheel. The transition wheels restrict the winding trajectory of the metal wire, reducing the possibility of sudden local tension increases or accidental friction with other components caused by wire deviation. At the same time, the detachable connection between the first and second transition frames and the adjustable function of the bolt clamps allow the distribution of the transition wheels to be adaptively adjusted according to the winding path of the metal wire, ensuring that the metal wire maintains a smooth transition during transportation, reducing stress concentration caused by excessive bending angles, and further reducing the risk of wire breakage.

[0018] Optionally, the outer surfaces of the plurality of transition wheels are covered with a wool felt layer.

[0019] By adopting the above technical solution, the soft texture of wool felt is used to provide support for the metal wire, avoiding surface scratches or coating peeling caused by excessive friction when the traditional hard transition wheel comes into contact with the metal wire, and reducing the risk of breakage of the metal wire caused by surface damage.

[0020] Optionally, a transparent protective cover is provided on the workbench, and the transparent protective cover covers the outer surface of the wire feeding roller.

[0021] By adopting the above technical solution, the transparent protective cover forms a physical protective barrier to prevent the free end from popping out when the wire suddenly breaks during the wire feeding process, thus avoiding safety hazards to the operators. Furthermore, due to its transparent nature, it does not affect the staff's real-time observation of the wire remaining amount and wire feeding status on the wire feeding wheel, making it convenient to replace the wire feeding wheel or handle abnormalities in a timely manner.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application sets up a wire breakage detection sensor and an alarm device. When the metal wire breaks, the wire breakage detection sensor detects the broken state of the metal wire and transmits the information to the control system, triggering the alarm device to remind the operator to shut down the winding machine in time. This reduces the possibility that the broken wire will not be detected in time and will cause a large number of broken wires to entangle and form clumps as the equipment runs. It also reduces the time that workers spend cleaning up clumps of wire, thereby improving the winding efficiency of the metal wire. 2. The embodiments of this application, by setting a tension compensation component, enable the metal wire to maintain a stable tension during the winding process, thereby reducing the risk of metal wire breakage caused by tension fluctuations; 3. This application reduces the possibility of sudden increase in local tension or accidental friction with other components caused by the wire deflection by setting a transition component and limiting the winding trajectory of the metal wire through the transition wheel.

Detailed Implementation

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a winding machine with a wire breakage self-detection device.

[0030] Reference Figure 1 and Figure 2A winding machine with a wire breakage self-inspection device includes a workbench 01, a placement frame 1 is installed on one side of the workbench 01, a wire feeding roller 02 for placing the wire feeding spool is rotatably connected to the placement frame 1, and a transparent protective cover 101 is installed on the placement frame 1. The transparent protective cover 101 covers the outer surface of the wire feeding roller 02 to prevent the free end from popping out when the metal wire suddenly breaks during the wire feeding process, thus avoiding safety hazards to the operator.

[0031] Reference Figure 1 and Figure 2 The workbench 01 is rotatably connected to a take-up roller 03 for placing the take-up spool on the side away from the placement frame 1. A transition component 2 is provided between the pay-off roller 02 and the take-up roller 03 on the workbench 01. When winding, the worker fixes the fully loaded pay-off spool on the pay-off roller 02 and the unloaded take-up spool on the take-up roller 03. Then, the metal wire on the pay-off spool is passed through the transition component 2 and connected to the take-up spool. The metal wire is wound onto the take-up spool by the rotation of the take-up roller 03.

[0032] Reference Figure 1 and Figure 2 The workbench 01 is equipped with a support assembly 3. Specifically, the support assembly 3 includes a column 31 that is detachably connected to the workbench 01. The column 31 is vertically arranged and an L-shaped support frame 32 is installed on the column 31. A detection plate 4 is detachably connected to the support frame 32 by bolt clamps (not shown in the figure). The detection plate 4 is located above the transparent protective cover 101.

[0033] Reference Figure 1 and Figure 2 The end of the detection plate 4 is rotatably connected to a guide wheel 41. A wire breakage detection sensor 42 is fixedly installed on the detection plate 4. The wire breakage detection sensor 42 is electrically connected to an alarm element 43 through a control system. In this embodiment, the alarm element 43 is a warning light installed on the detection plate 4. In this embodiment, the wire breakage sensor is an infrared photoelectric wire detector. When the metal wire moves normally, the slight vibration of the metal wire will periodically block the infrared light, forming a continuous pulse signal. When the wire breaks, the pulse frequency decreases significantly or disappears. The sensor analyzes the signal change through the demodulation circuit and determines the trigger state. The specific detection principle is existing technology and will not be described in detail here.

[0034] After being released from the reel, the metal wire passes through the guide wheel 41 and is then threaded inside the wire breakage detection sensor 42. When the metal wire breaks, the wire breakage detection sensor 42 detects the broken state of the metal wire and transmits the information to the control system, triggering the alarm 43 to remind the operator to shut down the winding machine in time. This reduces the possibility of the broken wire not being detected in time, which may lead to a large amount of wire tangling and forming a clump as the equipment runs. It also reduces the time workers spend cleaning up the clumps, thereby improving the winding efficiency of the metal wire.

[0035] Reference Figure 2 and Figure 3 The support frame 32 is provided with a tension compensation component 5. The tension compensation component 5 includes a fixed frame 51 provided on the support frame 32. A tension arm 52 is rotatably connected to the fixed frame 51. The end of the tension arm 52 extends out of the fixed frame 51 and is rotatably connected to a tension wheel 53. The metal wire passes through the wire breakage detection sensor 42 and abuts against the tension wheel 53.

[0036] Reference Figure 2 and Figure 3 One end of the fixed frame 51 is fixedly installed with a guide frame 54, and the other end is fixedly installed with a positioning pin (not shown in the figure). The tension arm 52 slides through the inside of the guide frame 54. A compensating tension spring 55 is provided on the fixed frame 51. One end of the compensating tension spring 55 is fixedly hooked to the positioning pin, and the other end is hooked to the tension arm 52.

[0037] When the tension of the metal wire increases, the additional tension acts on the tension wheel 53, driving the tension arm 52 to rotate. The tension arm 52 stretches the compensating spring 55, and the elastic force of the compensating spring 55 increases, thereby offsetting part of the additional tension and reducing the risk of the metal wire breaking due to the sudden increase in tension. When the tension of the metal wire decreases, the elastic force of the compensating spring 55 is greater than the force exerted by the metal wire on the tension wheel 53. The compensating spring 55 pulls the tension arm 52 to rotate in the opposite direction. The tension arm 52 drives the transition wheel 26 to tighten the metal wire, thereby increasing the tension of the metal wire and reducing the slack of the metal wire. In this way, the metal wire maintains a stable tension during the winding process, reducing the risk of metal wire breakage due to tension fluctuations.

[0038] Reference Figure 2 and Figure 3 The support frame 32 can be slidably sleeved on the outer surface of the column 31 along the axis of the column 31. The support frame 32 is fixed to the column 31 by the first locking bolt 321. A connecting seat 322 is slidably passed through the support frame 32. A pin 323 is rotatably connected inside the connecting seat 322. The fixing frame 51 can be rotatably sleeved on the outer surface of the pin 323 around the axis of the pin 323. The connecting seat 322 is fixed to the support frame 32 by the second locking bolt 324. The fixing frame 51 is fixed to the outer surface of the pin 323 by the third locking bolt 325.

[0039] During adjustment, workers can adjust the height of the support frame 32 on the column 31 by adjusting the tightness of the first locking bolt 321, adjust the horizontal position of the fixing frame 51 on the support frame 32 by adjusting the tightness of the second locking bolt 324, and adjust the angle of the fixing frame 51 by adjusting the tightness of the third locking bolt 325. In this way, the tension compensation component 5 can be adjusted in multiple dimensions, so that the position and angle of the tension compensation component 5 can be adapted to the needs of different winding paths of metal wire, thus improving the applicability of the winding machine.

[0040] Reference Figure 2and Figure 4 The transition assembly 2 includes a transition roller 21 fixedly installed on the workbench 01. The transition roller 21 is parallel to the axis of the take-up roller 03. A support block 22 is detachably connected to the transition roller 21. A first transition frame 23 is detachably connected to the support block 22 by bolt clamps (not shown in the figure). The first transition frame 23 is T-shaped. A second transition frame 24 is detachably connected to the end of the first transition frame 23 near the take-up roller 03 by bolts. A clamping plate 25 is detachably connected to the other end of the first transition frame 23 by bolts. Transition wheels 26 are rotatably connected to the first transition frame 23 and the second transition frame 24. In this embodiment, one transition wheel 26 is installed on the first transition frame 23 and two transition wheels 26 are installed on the second transition frame 24.

[0041] Reference Figure 2 and Figure 4 The outer surface of the transition wheel 26 is covered with a wool felt layer (not shown in the figure). The soft texture of the wool felt provides support for the metal wire and reduces the risk of breakage caused by surface damage to the metal wire.

[0042] After passing through the tensioning roller 53, the metal wire passes through the clamping plate 25 and multiple transition rollers 26 in sequence. This restricts the conveying path of the metal wire between the pay-off and take-up drums, reducing the possibility of sudden increases in local tension caused by wire deviation or accidental friction with other components. At the same time, the worker can adjust the distribution of the transition rollers 26 and clamping plate 25 according to the wire winding path through the detachable connection between the first transition frame 23 and the second transition frame 24 and the adjustment function of the bolt clamps. This ensures that the metal wire maintains a smooth transition during the conveying process, reduces stress concentration caused by excessive bending angles, and further reduces the risk of wire breakage.

[0043] The implementation principle of a winding machine with a wire breakage self-detection device in this application embodiment is as follows: During winding, the worker fixes a fully loaded pay-off spool on the pay-off roller 02 and an empty take-up spool on the take-up roller 03. Then, the metal wire on the pay-off spool passes sequentially through the guide wheel 41, the wire breakage detection sensor, the tension wheel 53, the clamping plate 25, and multiple transition wheels 26, and finally fixes the free end of the metal wire on the take-up spool. When the metal wire breaks, the wire breakage detection sensor 42 detects the broken state of the metal wire and transmits the information to the control system, triggering the alarm 43 to remind the operator to shut down the winding machine in time. This reduces the possibility that the broken wire will not be detected in time and will cause a large amount of wire to entangle and generate clumps as the equipment runs, reducing the time for workers to clean up the clumps, thereby improving the winding efficiency of the metal wire.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
