Description

Technical Field

[0001] This invention relates to the field of guiding equipment for wire coil winding machines, and more particularly to a winding guiding device for a circular cross-section wire coil winding machine. Background Technology

[0002] Currently, circular cross-section steel wire rings are usually wrapped using a winding machine. The working principle of the winding machine is to place the object to be wrapped in the center of the turntable, start the turntable motor to rotate, and naturally drive the turntable to rotate, so that the object is wrapped around the outside.

[0003] In existing winding machines, when winding steel wire rings, the ring core is passed through the center of the turntable, and then one end of the circular cross-section steel wire is passed through the guide roller and the winding device in sequence. It is then spot-welded to the surface of the ring core for fixation. Finally, the motor is started to drive the turntable in the winding device to rotate, which can drive the steel wire to wind around the surface of the ring core. However, the movement trajectory of the steel wire after passing through the guide roller is a back-and-forth oscillation. Therefore, when the steel wire oscillates upward or downward, it will squeeze the guide roller, which will increase the pressure at the contact point between the steel wire and the guide roller. Excessive pressure may cause plastic deformation of the steel wire, thus affecting the quality of the steel wire ring.

[0004] Based on this, we propose a winding guide device for a circular cross-section steel wire ring winding machine. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a winding guide device for a circular cross-section steel wire ring winding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winding guide device for a circular cross-section steel wire coil winding machine includes a mounting base and further includes:

[0008] The guiding mechanism includes two mounting boxes fixedly connected to the side wall of the mounting base. A sliding plate is slidably connected to the inner wall of each mounting box. Two adjusting rods are fixedly connected to the side wall of each sliding plate. One end of each adjusting rod passes through the side wall of the mounting box and is fixedly connected to a U-shaped frame. Two mounting slots are symmetrically formed on the inner wall of the U-shaped frame. A rotating shaft is rotatably connected to the inner wall of each mounting slot. A guide roller is fixedly connected to one end of each rotating shaft that is close to the other. A first lead screw is rotatably connected to the inner wall of each mounting box. The side wall of the first lead screw is threadedly connected to the sliding plate. A rotating rod is rotatably connected to the inner wall of each mounting box. A first bevel gear is fixedly connected to the side wall of the rotating rod. A second bevel gear is fixedly connected to the side wall of the first lead screw. The first and second bevel gears mesh with each other. One end of one rotating shaft passes through the side wall of the U-shaped frame and is fixedly connected to a driving wheel. One end of the rotating rod passes through the side wall of the mounting box and is fixedly connected to a driven wheel. The driving wheel is connected to the driven wheel via a synchronous belt.

[0009] Preferably, one of the rotating shaft sidewalls is fixedly fitted with a torsion spring, one end of which is fixedly connected to the inner wall of the mounting groove.

[0010] Preferably, a lubrication mechanism is installed on the guide roller. The lubrication mechanism includes an oil inlet chamber opened in the guide roller. The inner wall of the oil inlet chamber is provided with multiple oil outlet holes. A hollow groove is opened in one of the rotating shafts. The hollow groove is connected to the oil inlet chamber through a connecting groove. A rotary joint is fixedly connected to the side wall of the U-shaped frame through a bracket. One end of the rotating shaft passes through the side wall of the U-shaped frame and is fixedly connected to the rotary joint.

[0011] Preferably, the lubrication mechanism further includes an airbag fixedly connected to the upper end of the U-shaped frame, a one-way oil inlet pipe fixedly connected to the side wall of the airbag, a one-way oil outlet pipe fixedly connected to the inner wall of the airbag, and the other end of the one-way oil outlet pipe fixedly connected to a rotary joint.

[0012] Preferably, a tensioning mechanism is installed on the mounting box. The tensioning mechanism includes a groove formed on the side wall of the mounting box. A slider is slidably connected to the inner wall of the groove. A tensioning wheel is rotatably connected to the side wall of the slider via a pin. The driving wheel, the driven wheel, and the tensioning wheel are connected by a synchronous belt.

[0013] Preferably, the tensioning mechanism further includes a slide rod fixedly connected to the inner wall of the slide groove, the side wall of the slide rod being slidably connected to the slider, and a first spring being sleeved on the side wall of the slide rod, with both ends of the first spring being fixedly connected to the side wall of the slider and the inner wall of the slide groove, respectively.

[0014] Preferably, the inner wall of the mounting groove is symmetrically slidably connected with two pressure rods, and an arc-shaped damping plate is fixedly connected to one end of each pressure rod that is close to the other.

[0015] Preferably, a resistance adjustment mechanism is installed on the U-shaped frame. The resistance adjustment mechanism includes two first cavities symmetrically opened in the U-shaped frame, and a second cavity is opened in the U-shaped frame. One end of each of the two first cavities is connected to the second cavity. Two fixed rods are symmetrically slidably connected to the inner wall of the second cavity. One end of each of the two fixed rods extends into the first cavity and is fixedly connected to a slide cylinder. One end of the pressure rod extends into the slide cylinder, and a second spring is fixedly connected between the inner wall of the slide cylinder and the pressure rod.

[0016] Preferably, the resistance adjustment mechanism further includes a movable block slidably connected to the inner wall of the second cavity, two connecting rods symmetrically rotatably connected to the side wall of the movable block, the other ends of the two connecting rods being rotatably connected to one end of two fixed rods respectively, and a second lead screw rotatably connected to the inner wall of the second cavity, the side wall of the second lead screw being threadedly connected to the movable block.

[0017] Preferably, one end of the second lead screw passes through the side wall of the U-shaped frame and is fixedly connected with a cross nut.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting a guiding mechanism, the guide roller can move with the swing of the steel wire during the winding process. This not only keeps the pressure at the contact point between the steel wire and the guide roller within a reasonable range, but also reduces the bending curvature of the steel wire, thereby preventing plastic deformation of the steel wire caused by the swing of the steel wire.

[0020] 2. By setting a torsion spring, the pressure will decrease accordingly during the movement of the guide roller until the pressure decreases to the point that the guide roller can no longer rotate. At this time, the guide roller will stop rotating. When the steel wire begins to swing downward, the pressure between the steel wire and the guide roller will decrease to the minimum, and the friction will be reduced to the minimum. At this time, the torsion spring can overcome the friction and drive the rotating shaft to rotate in the opposite direction to reset. This can then drive the first lead screw to rotate in the opposite direction, drive the slide plate to move downward to reset, and drive the guide roller to move downward slowly. This ensures that the guide roller always keeps in contact with the steel wire, limits the steel wire, and prevents the steel wire from swinging back and forth during its movement, causing deviation in the travel path and resulting in irregular winding.

[0021] 3. By setting up a lubrication mechanism, the increased pressure between the steel wire and the guide roller causes the U-shaped frame to squeeze the air bladder during the movement of the guide roller. As a result, the lubricating oil in the air bladder enters the hollow groove through the one-way oil outlet pipe, and then enters the oil inlet chamber through the connecting groove. Finally, the lubricating oil flows out through multiple oil outlet holes, which lubricates the steel wire, reduces the stress between the steel wire and the guide roller, and further reduces the risk of plastic deformation of the steel wire.

[0022] 4. By setting up a damping adjustment mechanism and adjusting the resistance between the arc-shaped damping plate and the rotating shaft, the torque required for the rotating shaft to rotate can be adjusted. Therefore, when guiding softer steel wires, less torque is needed for the rotating shaft to rotate. During the winding process, when the pressure between the steel wire and the guide roller increases by a small amount, the guide roller can also move accordingly to reduce stress, resulting in a more sensitive response. This effectively ensures that softer steel wires do not undergo plastic deformation. Conversely, for harder steel wires, more torque is needed for the rotating shaft to rotate. During the winding process, a larger increase in pressure between the steel wire and the guide roller is required for the guide roller to move accordingly to reduce stress. This results in a more sluggish response, ensuring that the guide roller provides sufficient pressure to limit the movement. Attached Figure Description

[0032] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Reference Figure 1 - Figure 8 A winding guide device for a circular cross-section steel wire coil winding machine, comprising a mounting base 1, and further comprising:

[0034] The guiding mechanism includes two mounting boxes 2 fixedly connected to the side wall of the mounting base 1. A sliding plate 3 is slidably connected to the inner wall of each mounting box 2. Two adjusting rods 4 are fixedly connected to the side wall of the sliding plate 3. One end of each adjusting rod 4 passes through the side wall of the mounting box 2 and is fixedly connected to a U-shaped frame 5. Two mounting slots 6 are symmetrically formed on the inner wall of the U-shaped frame 5. A rotating shaft 7 is rotatably connected to the inner wall of each mounting slot 6. A guide roller 8 is fixedly connected to the end of each rotating shaft 7 that is close to each other. A first guide roller 8 is rotatably connected to the inner wall of the mounting box 2. The first lead screw 9 is threaded to the side wall of the slide plate 3. The inner wall of the mounting box 2 is rotatably connected to the rotating rod 10. The side wall of the rotating rod 10 is fixedly connected to the first bevel gear 11. The side wall of the first lead screw 9 is fixedly connected to the second bevel gear 12. The first bevel gear 11 and the second bevel gear 12 are meshed. One end of the rotating shaft 7 passes through the side wall of the U-shaped frame 5 and is fixedly connected to the driving wheel 13. One end of the rotating rod 10 passes through the side wall of the mounting box 2 and is fixedly connected to the driven wheel 14. The driving wheel 13 is connected to the driven wheel 14 through a synchronous belt.

[0035] Furthermore, under normal circumstances, when the wire travels along the wire profile, the two guide rollers 8 apply moderate surface pressure to the wire, maintaining the necessary limiting pressure without causing excessive pressure that could lead to plastic deformation. At this pressure, the friction between the wire and the guide rollers 8 during wire travel will not cause the guide rollers 8 to rotate. However, during the winding process of the wire coil, the wire will exhibit an upward or downward oscillating trajectory within the winding device. At this time, the wire will gradually increase its pressure on the guide rollers 8. As the pressure increases, plastic deformation may occur, and the friction between the wire and the guide rollers 8 will increase. When the friction increases to the point where the guide rollers 8 rotate, the rotation of the guide rollers 8 will drive the rotating shaft 7 to rotate, thereby driving the driving wheel 13 to rotate, which in turn drives the driven wheel 14 to rotate, which in turn drives the rotating rod 10 to rotate, which in turn drives the first bevel gear 11 to rotate, which in turn drives the second bevel gear 12 to rotate, which in turn drives the first lead screw 9 to rotate, causing the slide plate 3 to slide upwards (as shown). Figure 5 As shown), the slide plate 3 will move upward via the adjusting rod 4, which in turn will drive the U-shaped frame 5 to move upward, and drive the guide roller 8 to move upward. At this time, due to the upward displacement of the guide roller 8, the pressure between the guide roller 8 and the steel wire will decrease, and the bending curvature of the steel wire will also decrease, thereby preventing the steel wire from undergoing plastic deformation due to the swing of the steel wire. Conversely, when the steel wire swings downward, the guide roller 8 below will move downward synchronously.

[0036] One of the rotating shafts 7 has a torsion spring 15 fixedly sleeved on its side wall, and one end of the torsion spring 15 is fixedly connected to the inner wall of the mounting groove 6.

[0037] Furthermore, as the guide roller 8 moves, the pressure decreases accordingly until it decreases to the point where the guide roller 8 can no longer rotate. At this point, the guide roller 8 stops rotating. When the steel wire begins to swing downwards, the pressure between the steel wire and the guide roller 8 decreases to its minimum, and the friction is reduced to its minimum. At this point, the torsion spring 15 can overcome the friction and drive the rotating shaft 7 to rotate in the opposite direction to reset. This, in turn, can drive the first lead screw 9 to rotate in the opposite direction, drive the slide plate 3 to move downwards to reset, and drive the guide roller 8 to slowly move downwards. This ensures that the guide roller 8 always keeps in contact with the steel wire, limiting the movement of the steel wire and preventing it from swinging back and forth during its travel, causing deviation in the travel path and resulting in irregular winding.

[0038] A lubrication mechanism is installed on the guide roller 8. The lubrication mechanism includes an oil inlet chamber 16 opened in the guide roller 8. Multiple oil outlet holes 17 are opened on the inner wall of the oil inlet chamber 16. A hollow groove 18 is opened in one of the rotating shafts 7. The hollow groove 18 is connected to the oil inlet chamber 16 through a connecting groove 19. A rotary joint 20 is fixedly connected to the side wall of the U-shaped frame 5 through a bracket. One end of the rotating shaft 7 passes through the side wall of the U-shaped frame 5 and is fixedly connected to the rotary joint 20.

[0039] The lubrication mechanism also includes an airbag 21 fixedly connected to the upper end of the U-shaped frame 5. A one-way oil inlet pipe 22 is fixedly connected to the side wall of the airbag 21. The other end of the one-way oil inlet pipe 22 is connected to an external container storing lubricating oil. The one-way oil inlet pipe 22 only allows external lubricating oil to enter the airbag 21. A one-way oil outlet pipe 23 is fixedly connected to the inner wall of the airbag 21. The one-way oil outlet pipe 23 only allows the lubricating oil in the airbag 21 to be discharged. The other end of the one-way oil outlet pipe 23 is fixedly connected to the rotary joint 20.

[0040] Furthermore, the increased pressure between the steel wire and the guide roller 8 causes the U-shaped frame 5 to move and compress the air bladder 21 during the movement of the guide roller 8. Consequently, the lubricating oil in the air bladder 21 enters the hollow groove 18 through the one-way oil outlet pipe 23, and then enters the oil inlet chamber 16 through the connecting groove 19. Finally, the lubricating oil flows out through multiple oil outlet holes 17, which lubricates the steel wire and reduces the stress between the steel wire and the guide roller 8, further reducing the risk of plastic deformation of the steel wire. Moreover, the lubricating oil is only pumped out when the pressure between the steel wire and the guide roller 8 increases, and it will not be pumped out under normal circumstances, which can effectively reduce the waste of lubricating oil. When the guide roller 8 returns to its original position, it will stretch the air bladder 21. At this time, the external lubricating oil will be drawn into the air bladder 21 through the one-way oil inlet pipe 22 for storage and backup.

[0041] The mounting box 2 is equipped with a tensioning mechanism, which includes a slide groove 24 opened on the side wall of the mounting box 2. A slider 25 is slidably connected to the inner wall of the slide groove 24. A tensioning wheel 26 is rotatably connected to the side wall of the slider 25 via a pin. The driving wheel 13, the driven wheel 14 and the tensioning wheel 26 are connected by a synchronous belt.

[0042] The tensioning mechanism also includes a slide rod 27 fixedly connected to the inner wall of the slide groove 24. The side wall of the slide rod 27 is slidably connected to the slider 25. A first spring 28 is sleeved on the side wall of the slide rod 27. The two ends of the first spring 28 are fixedly connected to the side wall of the slider 25 and the inner wall of the slide groove 24, respectively.

[0043] It should be noted that when the U-shaped frame 5 moves, it will drive the drive wheel 13 to move. At this time, the slider 25 will move under the action of the first spring 28, thereby driving the tension wheel 26 to move horizontally, so that the synchronous belt always remains taut, thus ensuring the effective transmission of power.

[0044] Two pressure rods 29 are symmetrically slidably connected to the inner wall of the mounting groove 6. An arc-shaped damping plate 30 is fixedly connected to the end of each pressure rod 29 that is close to each other.

[0045] A resistance adjustment mechanism is installed on the U-shaped frame 5. The resistance adjustment mechanism includes two first cavities 31 symmetrically opened in the U-shaped frame 5. A second cavity 32 is opened in the U-shaped frame 5. One end of each of the two first cavities 31 is connected to the second cavity 32. Two fixed rods 33 are symmetrically slidably connected to the inner wall of the second cavity 32. One end of each fixed rod 33 extends into the first cavity 31 and is fixedly connected to a slide cylinder 34. One end of a pressure rod 29 extends into the slide cylinder 34 and is set therein. A second spring 35 is fixedly connected between the inner wall of the slide cylinder 34 and the pressure rod 29.

[0046] The resistance adjustment mechanism also includes a movable block 36 that is slidably connected to the inner wall of the second cavity 32. Two connecting rods 37 are symmetrically rotatably connected to the side wall of the movable block 36. The other ends of the two connecting rods 37 are rotatably connected to one end of two fixed rods 33 respectively. A second lead screw 38 is rotatably connected to the inner wall of the second cavity 32. The side wall of the second lead screw 38 is threadedly connected to the movable block 36.

[0047] One end of the second lead screw 38 passes through the side wall of the U-shaped frame 5 and is fixedly connected to a cross nut 39.

[0048] Furthermore, when guiding steel wires of different hardness, the Phillips head nut 39 can be turned using an external Torx screwdriver, which can rotate the second lead screw 38, thereby causing the moving block 36 to slide within the second cavity 32. The moving block 36, through the connecting rod 37, causes the two fixed rods 33 to slide closer or further apart, thus changing the compression degree of the second spring 35. The greater the compression degree of the second spring 35, the greater the reaction force it provides to the arc-shaped damping plate 30, and consequently, the greater the pressure exerted by the arc-shaped damping plate 30 on the rotating shaft 7. Therefore, the damping of the rotating shaft 7 is greater, and the rotation of the rotating shaft 7 requires greater torque. Conversely, the smaller the compression degree of the second spring 35, the less torque is required for the rotation of the rotating shaft 7. Therefore, when guiding softer steel wires, the Phillips head nut 39 can be turned using a Torx screwdriver. Nut 39 reduces the compression of the second spring 35, thus requiring less torque for the shaft 7 to rotate. During winding, when the pressure between the wire and guide roller 8 increases only slightly, the guide roller 8 can move accordingly to reduce stress, resulting in a more sensitive response. This effectively prevents the softer wire from undergoing plastic deformation. Conversely, harder wires do not easily undergo plastic deformation, allowing the second spring 35 to compress more. Consequently, the shaft 7 requires more torque to rotate, requiring a larger increase in pressure for the guide roller 8 to move and reduce stress. This more sluggish response ensures the guide roller 8 provides sufficient pressure for limiting its movement.

[0049] In this invention, the mounting base 1 is fixed to the wire coil winding machine using bolts, and then one end of the wire is passed from the right side to the left side of the guide roller 8 (e.g., ...). Figure 1 As shown), the steel wire is then passed through the winding device, and finally spot-welded to the core. During the winding process, the guide roller 8 can limit the movement of the steel wire to prevent the steel wire from swinging back and forth and causing irregular winding.

[0050] Under normal circumstances, when the wire travels along the wire guide, the two guide rollers 8 apply moderate surface pressure to the wire, maintaining the necessary limiting pressure without causing excessive pressure that could lead to plastic deformation. At this pressure, the friction between the wire and the guide rollers 8 during wire travel will not cause the guide rollers 8 to rotate. However, during the winding process of the wire coil, the wire will exhibit an upward or downward oscillating trajectory within the winding device. At this time, the wire will gradually increase its pressure on the guide rollers 8. As the pressure increases, plastic deformation may occur, and the friction between the wire and the guide rollers 8 will increase. When the friction increases to the point where the guide rollers 8 rotate, the rotation of the guide rollers 8 will drive the rotating shaft 7, which in turn drives the driving wheel 13, which in turn drives the driven wheel 14, which in turn drives the rotating rod 10, which in turn drives the first bevel gear 11, which in turn drives the second bevel gear 12, which in turn drives the first lead screw 9, causing the slide plate 3 to slide upwards (as shown). Figure 5 As shown), the slide plate 3 will move upward via the adjusting rod 4, which in turn will drive the U-shaped frame 5 to move upward, and drive the guide roller 8 to move upward. At this time, due to the upward displacement of the guide roller 8, the pressure between the guide roller 8 and the steel wire will decrease, and the bending curvature of the steel wire will also decrease, thereby preventing the steel wire from undergoing plastic deformation due to the swing of the steel wire. Conversely, when the steel wire swings downward, the guide roller 8 below will move downward synchronously.

[0051] As the guide roller 8 moves, the pressure decreases accordingly until it becomes so low that the guide roller 8 can no longer rotate. At this point, the guide roller 8 stops rotating. When the steel wire begins to swing downwards, the pressure between the steel wire and the guide roller 8 decreases to its minimum, and the friction is reduced to its minimum. At this point, the torsion spring 15 can overcome the friction and drive the rotating shaft 7 to rotate in the opposite direction to reset. This, in turn, drives the first lead screw 9 to rotate in the opposite direction, causing the slide plate 3 to move downwards to reset. This causes the guide roller 8 to slowly move downwards, ensuring that the guide roller 8 always remains in contact with the steel wire, thus limiting the movement of the steel wire and preventing it from swinging back and forth during its journey. This would cause the wire to deviate from its path and result in irregular winding.

[0052] The increased pressure between the steel wire and the guide roller 8 causes the U-shaped frame 5 to move and compress the air bladder 21 during the movement of the guide roller 8. As a result, the lubricating oil in the air bladder 21 enters the hollow groove 18 through the one-way oil outlet pipe 23, and then enters the oil inlet chamber 16 through the connecting groove 19. Finally, the lubricating oil flows out through multiple oil outlet holes 17, which lubricates the steel wire and reduces the stress between the steel wire and the guide roller 8. This further reduces the risk of plastic deformation of the steel wire. The lubricating oil is only pumped out when the pressure between the steel wire and the guide roller 8 increases. Under normal circumstances, it will not be pumped out, which can effectively reduce the waste of lubricating oil. When the guide roller 8 returns to its original position, it stretches the air bladder 21. At this time, the external lubricating oil is drawn into the air bladder 21 through the one-way oil inlet pipe 22 and stored for later use.

[0053] When guiding steel wires of different hardness, the Phillips head nut 39 can be turned using an external Torx screwdriver, which will rotate the second lead screw 38. This will cause the moving block 36 to slide within the second cavity 32. The moving block 36 will then drive the two fixed rods 33 to slide closer or further apart via the connecting rod 37, thereby changing the compression degree of the second spring 35. The greater the compression degree of the second spring 35, the greater the reaction force it provides to the arc-shaped damping plate 30. Consequently, the arc-shaped damping plate 30 exerts greater pressure on the rotating shaft 7, resulting in greater damping during the rotation of the rotating shaft 7. Therefore, the rotation of the rotating shaft 7 requires greater torque. Conversely, the smaller the compression degree of the second spring 35, the less torque is required for the rotation of the rotating shaft 7. Therefore, when guiding softer steel wires, the Phillips head nut 39 can be turned... 9. This reduces the compression of the second spring 35, resulting in less torque required for the rotating shaft 7 to rotate. During the winding process, when the pressure between the wire and the guide roller 8 increases slightly, the guide roller 8 can also move accordingly to reduce stress, making the response more sensitive. This effectively ensures that softer wires do not undergo plastic deformation. Conversely, harder wires do not easily undergo plastic deformation, thus increasing the compression of the second spring 35. Consequently, the rotating shaft 7 requires more torque to rotate. During the winding process, a larger increase in pressure between the wire and the guide roller 8 is needed for the guide roller 8 to move accordingly to reduce stress, resulting in a more sluggish response. This ensures that the guide roller 8 provides sufficient pressure to limit its movement.
