Description

Technical Field

[0001] The present application relates to the technical field of wire production, and particularly relates to a wire feeding tension mechanism for a winding machine. Background Art

[0002] Currently, during the winding process of a transformer coil, the stability of the wire feeding tension directly affects the quality of the coil. When the wire feeding tension is uneven or there is a speed difference before and after, it is easy to cause the wire to deform and break or the situation of wire feeding, thus affecting the wire feeding quality of the wire.

[0003] Existing wire feeding tension mechanisms mostly adopt manual adjustment or simple spring-type tension devices. Although these methods can ensure the basic requirements of wire feeding tension to a certain extent, there are still many problems in actual production. With the improvement of the degree of automation, the requirements for wire feeding tension are also getting higher and higher. The traditional manual adjustment method can no longer meet the high-efficiency and precise requirements of modern production. Therefore, it is particularly important to develop a mechanism that can automatically adjust the wire feeding tension. Summary of the Invention

[0004] In order to achieve uniform tension during the wire feeding process and reduce the possibility of wire breakage, the present application provides a wire feeding tension mechanism for a winding machine.

[0005] The wire feeding tension mechanism for a winding machine provided by the present application adopts the following technical solutions:

[0006] A wire feeding tension mechanism for a winding machine includes a frame, a wire pay-off reel, a tension adjustment assembly, and a stability assembly. A wire pay-off rotating shaft is vertically rotatably arranged on the frame. The tension adjustment assembly includes a lifting plate, which is horizontally arranged above the frame. The wire pay-off reel is sleeved on the wire pay-off rotating shaft and is placed on the lifting plate. A driving member for driving the lifting plate to move in the vertical direction is arranged on the frame. The stability assembly includes a supporting vertical plate, a first driving wire wheel, a second driving wire wheel, and a floating wire wheel. The supporting vertical plate is vertically arranged on the frame. The first driving wire wheel, the second driving wire wheel, and the floating wire wheel are all rotatably arranged on the same side of the supporting vertical plate. The floating wire wheel is arranged between the first driving wire wheel and the second driving wire wheel. The floating wire wheel is slidably arranged on the supporting vertical plate in the vertical direction. A counterweight is arranged on the floating wire wheel. A first driving motor and a second driving motor are arranged on the supporting vertical plate. The first driving motor is in transmission connection with the first driving wire wheel, and the second driving motor is in transmission connection with the second driving wire wheel.

[0007] By adopting the above technical solutions, when the winding machine feeds wire, the wire pay-off reel pays off wire. For different wire tensions, the driving source drives the lifting plate to move to adjust the wire pay-off tension.

[0008] The wire after wire pay-off sequentially passes through a first driving wire wheel, a floating wire wheel and a second driving wire wheel. Since a counterweight is arranged on the floating wire wheel, the pressure exerted by the floating wire wheel on the wire is always kept constant, and at the same time, the wire is always kept taut. Through the mutual cooperation of the machine frame, the wire pay-off reel, the tension adjusting assembly and the stabilizing assembly, the adjustment of the wire feeding tension is realized, and the effects of uniform tension in the wire feeding process and reduction of the possibility of wire breakage are achieved.

[0009] Optionally, a sliding groove is vertically formed on one side of the supporting vertical plate close to the floating wire wheel, several counterweights are slidably arranged vertically in the sliding groove, a connecting hole is arranged on one side of the counterweight far from the bottom of the sliding groove, a connecting shaft is arranged on the floating wire wheel, and the end of the connecting shaft is inserted into the connecting hole.

[0010] By adopting the above technical solution, for wires of different specifications, different wire feeding tensions are required. The connecting shaft is inserted into the connecting hole of the corresponding counterweight, and multiple counterweights are stacked together to realize the adjustment of the wire feeding tension.

[0011] Optionally, a connecting cover plate is arranged on one side of the supporting vertical plate close to the floating wire wheel. The connecting cover plate covers the sliding groove. A connecting sliding groove is arranged vertically on the connecting cover plate. The connecting sliding groove is correspondingly arranged with the connecting hole. A connecting slider is slidably arranged in the connecting sliding groove. The connecting slider is slidably connected with the connecting shaft. An anti-detachment spring is sleeved on the connecting shaft. One end of the anti-detachment spring is connected with the connecting slider, and the other end is connected with the floating wire wheel. In the natural state, the end of the connecting shaft is embedded in the connecting hole under the action of the anti-detachment spring.

[0012] By adopting the above technical solution, the setting of the anti-detachment spring realizes the automatic reset of the connecting shaft and reduces the possibility of the connecting shaft coming out of the connecting hole during use.

[0013] Optionally, a first induction switch and a second induction switch are arranged on the connecting cover plate. The first induction switch and the second induction switch are located on the same side of the connecting sliding groove. The first induction switch is located below the second induction switch. The first induction switch is in transmission connection with the first driving motor, and the second induction switch is in transmission connection with the second driving motor.

[0014] By adopting the above technical solution, when the rotation speed of the first driving wire wheel is greater than that of the second driving wire wheel, the floating wire wheel descends. When the floating wire wheel descends to a position corresponding to the first induction switch, the first driving motor receives an electrical signal and the rotation speed of the first driving motor decreases. Similarly, when the rotation speed of the second driving wire wheel is greater than that of the first driving wire wheel, the floating wire wheel ascends. When the floating wire wheel descends to a position corresponding to the second induction switch, the rotation speed of the second driving motor decreases. Through the settings of the first induction switch and the second induction switch, the rotation speed adjustment of the first driving wire wheel and the second driving wire wheel is achieved, reducing the possibility of the metal wire breaking or becoming loose.

A driving member for driving the moving block to move in the vertical direction is provided on the L-shaped mounting frame. Two wire guiding wheels are rotatably disposed on one side of the moving block, and the edges of the two wire guiding wheels are in contact with each other.

[0016] By adopting the above technical solution, the metal wire is wound around the wire pay-off reel in a certain pattern, and the positions of the two wire guiding wheels need to correspond to the metal wire. The settings of the moving block and the wire guiding wheels achieve the correspondence between the wire guiding wheels and the wire pay-off position, having the effects of guiding the wire releasing direction of the metal wire and stabilizing the wire releasing tension.

[0017] Optionally, the driving member includes an adjusting screw, a limiting rod, and a contact switch.

One contact switch is provided on the bottom surface of the horizontal portion and the top surface of the lifting plate respectively. The contact switches are electrically connected to the driving source, and the two contact switches are correspondingly disposed with the moving block in the vertical direction.

[0018] By adopting the above technical solution, the adjusting screw rotates under the drive of the driving source, and the limiting block moves in the vertical direction. When the moving block moves to squeeze the upper or lower contact switch, the adjusting screw rotates in the reverse direction, causing the moving block to move in the reverse direction, so that the wire guiding wheels can always correspond to the wire pay-off position.

[0020] By adopting the above technical solution, when the wire feeding speed of the second drive wheel is greater than the wire feeding speed of the first drive wheel, the floating wheel rises, and when the floating wheel is squeezed by the pressing plate located above, the output shaft of the driving cylinder located next to the second drive wheel is extended, and the driving ring slides toward the direction close to the friction block.

[0039] Refer to Figure 1 and Figure 2 , the mounting L-shaped frame 32 is arranged on the top surface of the lifting plate 31. The mounting L-shaped frame 32 includes a vertical portion and a horizontal portion arranged at its top end. The adjusting motor 37 is arranged at the top end of the horizontal portion.

The limiting block 36 is fixedly connected to the top end of the limiting rod 35. Two wire guiding wheels 33 are rotatably connected to one of the vertical side walls of the moving block 34. One end of the metal wire is wound around the wire paying-off cylinder 2. The metal wire passes between the two wire guiding wheels 33 and abuts against both wire guiding wheels 33 simultaneously. One contact switch 39 is arranged at the bottom end of the horizontal portion and one is arranged on the top surface of the lifting plate 31. The two contact switches 39 are arranged corresponding to the moving block 34 in the vertical direction.

[0040] Refer to Figure 2 and Figure 3 , the stabilizing assembly 4 is arranged on the top surface of the frame 1. The stabilizing assembly 4 includes a supporting vertical plate 41, a counterweight 42, a guiding rod 43, a connecting cover 44, a connecting slider 45, a first driving wire wheel 46, a second driving wire wheel 47 and a floating wire wheel 48. The supporting vertical plate 41 is vertically and fixedly connected to the top surface of the frame 1. The supporting vertical plate 41 is arranged on the side of the mounting L-shaped frame 32 away from the wire paying-off rotating shaft 5. Both the first driving wire wheel 46 and the second driving wire wheel 47 are rotatably arranged on one side of the supporting vertical plate 41. A rotating shaft 49 is connected to both the first driving wheel and the second driving wheel. The first driving wire wheel 46 is located on the side of the second driving wire wheel 47 close to the mounting L-shaped frame 32. A first driving motor 11 and a second driving motor 12 are arranged on the supporting vertical plate 41. The output shaft of the first driving motor 11 is in transmission connection with the rotating shaft 49 of the first driving wheel. The output shaft of the second driving motor 12 is in transmission connection with the rotating shaft 49 of the second driving wheel.

[0041] Referring to Figure 2 and Figure 3 On the supporting vertical plate 41, a sliding groove 411 is formed along the vertical direction. The sliding groove 411 is arranged between the first driving wire wheel 46 and the second driving wire wheel 47. A plurality of counterweight blocks 42 are slidably arranged in the sliding groove 411. Two guide rods 43 are connected along the length direction of the sliding groove 411. The counterweight blocks 42 are slidably connected with the two guide rods 43. The connecting cover 44 is connected to one side of the supporting vertical plate 41 by bolts and seals the sliding groove 411. A connecting sliding groove 441 is formed along the vertical direction on the connecting cover 44. The inner cavity of the connecting sliding groove 441 is communicated with the inner cavity of the sliding groove 411. A connecting slider 45 is slidably arranged in the connecting sliding groove 441. A connecting shaft 13 is horizontally slidably connected to the connecting slider 45. One end of the connecting shaft 13 extends into the sliding groove 411, and the other end of the connecting shaft 13 is connected to the floating wire wheel 48. The height of the floating wire wheel 48 is lower than the heights of the first driving wire wheel 46 and the second driving wire wheel 47. An anti-disengagement spring 14 is sleeved on the connecting shaft 13. One end of the anti-disengagement spring 14 is connected to the connecting slider 45, and the other end is connected to the floating wire wheel 48. Connecting holes 421 are formed on one side of the counterweight blocks 42 close to the connecting cover 44. The positions of the connecting holes 421 correspond to the connecting sliding groove 441. The connecting shaft 13 is embedded in the connecting hole 421 of one of the counterweight blocks 42 under the action of the anti-disengagement spring 14.

[0042] Referring to Figure 1 On the side of the connecting cover 44 away from the supporting vertical plate 41, a first induction switch 15 and a second induction switch 16 are connected. The first induction switch 15, the second induction switch 16 and the floating wire wheel 48 are arranged corresponding to each other in the vertical direction. The first induction switch 15 is located below the second induction switch 16. The first induction switch 15 is electrically connected to the first driving motor 11, and the second induction switch 16 is electrically connected to the second driving motor 12. The wire passing through the two wire wheels 33 successively bypasses above the first driving wire wheel 46, below the floating wire wheel 48 and above the second driving wire wheel 47.

[0043] Referring to Figure 1 and Figure 2, when the wire winding machine feeds the wire, the wire releasing motor 6 starts and drives the wire releasing rotating shaft 5 to rotate, and the wire releasing cylinder 2 rotates with the wire releasing rotating shaft 5 to realize automatic wire releasing. For different wire releasing conditions and wire tensions, the lifting cylinder 7 drives the lifting plate 31 and the wire releasing cylinder 2 to move in the vertical direction to adjust the wire releasing tension. The setting of the fixing ring 8, the pressing ring 9 and the pressing spring 10 realizes the pressing of the wire releasing cylinder 2 and the lifting plate 31, so that the wire releasing cylinder 2 can always abut against the top surface of the lifting plate 31. Since the metal wire is wound around the wire releasing cylinder 2 in a certain pattern, the positions of the two wire guiding wheels 33 need to correspond to the positions of the metal wire on the wire releasing cylinder 2. The adjusting motor 37 starts to drive the adjusting screw 38 to rotate. Under the limiting and guiding action of the limiting rod 35 and the driving action of the adjusting screw 38, the limiting block 36 moves in the vertical direction. When the moving block 34 moves to contact the upper or lower contact switch 39, the adjusting motor 37 receives the electrical signal from the contact switch 39, and the adjusting motor 37 reverses, and the adjusting screw 38 rotates in the reverse direction, so that the moving block 34 moves in the reverse direction. The setting of the contact switch 39 realizes the correspondence between the wire guiding wheel 33 and the wire releasing position, and has the effects of guiding the wire releasing direction of the metal wire and stabilizing the wire releasing tension.

[0044] Refer to Figure 2 and Figure 3 , the wire after wire releasing passes through the first driving wire wheel 46, the floating wire wheel 48 and the second driving wire wheel 47 in sequence. The first driving motor 11 and the second driving motor 12 drive the first driving wire wheel 46 and the second driving wire wheel 47 to rotate, realizing the driving of the metal wire. Since the connecting shaft 13 of the floating wire wheel 48 is inserted into the connecting hole 421 of the corresponding counterweight block 42, the pressure exerted by the floating wire wheel 48 on the metal wire always remains constant, realizing the stabilization of the wire releasing tension and keeping the metal wire always in a tensioned state. For metal wires of different specifications, different wire releasing tensions are required. Pull the floating wire wheel 48 away from the connecting cover 44, the end of the connecting shaft 13 disengages from the connecting hole 421, move the connecting shaft 13 to the connecting hole 421 of the corresponding counterweight block 42, release the floating wire wheel 48, and the connecting shaft 13 is embedded in the connecting hole 421 of the corresponding counterweight block 42 under the action of the anti-detachment spring 14, realizing the adjustment of the metal wire tension.

[0045] Refer to Figure 2 and Figure 3, when the rotation speed of the first driving wire wheel 46 is greater than that of the second driving wire wheel 47, the floating wire wheel 48 descends along with the wire paying-off process of the metal wire. When the floating wire wheel 48 descends to a position corresponding to the first induction switch 15, the first driving motor 11 receives an electrical signal and the rotation speed of the first driving motor 11 decreases. When the rotation speed of the second driving wire wheel 47 is greater than that of the first driving wire wheel 46, the floating wire wheel 48 ascends along with the wire paying-off process of the metal wire. When the floating wire wheel 48 descends to a position corresponding to the second induction switch 16, the second driving motor 12 receives an electrical signal and the rotation speed of the second driving motor 12 decreases. Through the settings of the first induction switch 15 and the second induction switch 16, the rotation speed adjustment of the first driving wire wheel 46 and the second driving wire wheel 47 is realized, so that the driving speeds before and after the floating wire wheel 48 are consistent, and further reduces the possibility of the metal wire breaking or becoming loose during the wire feeding process due to inconsistent wire feeding speeds before and after.

[0046] The implementation principle of a wire feeding tension mechanism for a winding machine in Embodiment 1 of the present application is as follows: When the winding machine feeds wire, the wire pay-off reel 2 rotates with the wire pay-off rotating shaft 5 to achieve automatic wire pay-off. For different wire pay-off situations and wire tensions, the lifting cylinder 7 drives the lifting plate 31 and the wire pay-off reel 2 to move in the vertical direction to adjust the wire pay-off tension. The setting of the contact switch 39 realizes the correspondence between the guide wire wheel 33 and the wire pay-off position, and has the effects of guiding the wire pay-off direction of the metal wire and stabilizing the wire pay-off tension.

[0047] The wire after wire pay-off passes through the first driving wire wheel 46, the floating wire wheel 48, and the second driving wire wheel 47 in sequence. The connecting shaft 13 of the floating wire wheel 48 is inserted into the connecting hole 421 of the counterweight 42, so that the pressure exerted by the floating wire wheel 48 on the metal wire always remains constant, realizing the stabilization of the wire pay-off tension. The settings of the first induction switch 15 and the second induction switch 16 make the driving speeds before and after the floating wire wheel 48 consistent, and further reduce the possibility of the metal wire breaking or becoming loose during the wire feeding process due to inconsistent wire feeding speeds before and after.

A diaphragm spring 20 is provided on the side of the friction block 19 away from the transmission block 18. The diaphragm spring 20 is sleeved on the rotating shaft 49. The diaphragm spring 20 includes a connecting ring 201 and an elastic spring 202. The connecting ring 201 is connected to the friction block 19, and a plurality of elastic springs 202 are connected along the radial direction on the inner ring wall of the connecting ring 201. The end of the elastic spring 202 extends obliquely in a direction away from the friction block 19. A limiting ring 21 is sleeved on the rotating shaft 49 . The limiting ring 21 is located between the elastic spring sheet 202 and the friction block 19 . The limiting ring 21 abuts against the elastic spring sheet 202 .

[0051] Reference Figure 6, a driving ring 22 is provided on the sliding sleeve of the rotating shaft 49, and the driving ring 22 is arranged on the side of the diaphragm spring 20 away from the friction block 19. Two driving cylinders 23 are arranged on the support vertical plate 41, and the two driving cylinders 23 are arranged corresponding to the two rotating shafts 49. The output shaft of the driving cylinder 23 extends toward the direction of the supporting vertical plate 41 and is arranged parallel to the rotating shaft 49. A mounting plate 24 is connected to the output shaft of the driving cylinder 23, and the mounting plate 24 is connected to the driving ring 22. One end of the first connecting hose 176 is connected to the cylinder body of the driving cylinder 23 located next to the first driving wire wheel 46, and one end of the second connecting hose 177 is connected to the cylinder body of the driving cylinder 23 located next to the second driving wire wheel 47. In the natural state, the driving ring 22 is arranged to fit with the end of the elastic spring 202, and the friction block 19 is arranged to fit with the transmission block 18.

[0052] The implementation principle of a wire feeding tension mechanism for a winding machine in Example 2 of the present application is as follows: when the floating wire wheel 48 moves in the vertical direction under the action of the wire feeding speed difference, when the wire feeding speed of the second driving wire wheel 47 is greater than the wire feeding speed of the first driving wire wheel 46, the position of the floating wire wheel 48 rises, and when the floating wire wheel 48 rises to contact with the pressing plate 171 located above, the gas in the pressing cylinder 173 located above is input into the driving cylinder 23 next to the second driving wire wheel 47 through the second connecting hose 177 under the action of the piston plate 172, and the output shaft of the driving cylinder 23 extends and drives the driving ring 22 to move toward the direction close to the friction block 19. The elastic spring 202 is tilted up under the driving of the driving ring 22 and the limiting effect of the limiting ring 21, driving the connecting ring 201 to move in the direction away from the transmission block 18. The friction block 19 moves with the connecting ring 201, so that the friction between the friction block 19 and the transmission block 18 is reduced, the speed of the second driving wire wheel 47 is reduced, and the floating wire wheel 48 is reduced in height and separated from the upper pressing plate 171. The pressing plate 171 is reset under the action of the pressing spring 175, and the piston plate 172 moves downward, drawing the gas in the driving cylinder 23 back into the pressing cylinder 173 through the second connecting hose 177, shortening the output shaft of the driving cylinder 23, and the driving ring 22 moves in the opposite direction. The diaphragm spring 20 is reset, and the friction block 19 contacts the transmission block 18 again to realize transmission.

[0053] Referring to the figure, similarly, when the wire feeding speed of the first driving wire wheel 46 is greater than the wire feeding speed of the second driving wire wheel 47, the position of the floating wire wheel 48 is lowered. When the floating wire wheel 48 is lowered to press with the pressing plate 171 below, the above operation is repeated to realize the deceleration of the first driving wire wheel 46.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
