[0002] At present, in the process of transformer coil winding, the stability of wire feeding tension directly affects the quality of the coil. When the wire feeding tension is uneven or there is a speed difference between the front and back, it is easy to cause the metal wire to deform and break or wire feeding problems, thus affecting the wire feeding quality.

[0007] The metal wire that has been paid out passes through the first driving wire wheel, the floating wire wheel and the second driving wire wheel in sequence.

[0036] Reference Figure 2 and Figure 3 The support vertical plate 41 is provided with a sliding groove 411 along the vertical direction, and 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, and two guide rods 43 are connected in the sliding groove 411 along the length direction thereof, and the counterweight block 42 is slidably connected to the two guide rods 43.

One end of the connecting shaft 13 extends into the sliding groove 411. The other end of the connecting shaft 13 is connected to the floating line wheel 48. The height of the floating line wheel 48 is lower than the height of the first driving line wheel 46 and the second driving line wheel 47. The connecting shaft 13 is sleeved with an anti-slip spring 14. One end of the anti-slip spring 14 is connected to the connecting slider 45, and the other end is connected to the floating line wheel 48. The counterweight 42 is provided with a connecting hole 421 on one side close to the connecting cover 44. The position of the connecting hole 421 is set corresponding to the connecting slide groove 441. The connecting shaft 13 is embedded in the connecting hole 421 of one of the counterweights 42 under the action of the anti-slip spring 14.

[0037] Reference Figure 1 The first induction switch 15 and the second induction switch 16 are connected to the side of the connection cover 44 away from the support vertical plate 41. The first induction switch 15, the second induction switch 16 and the floating wire wheel 48 are arranged correspondingly in the vertical direction, and 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 metal wire passing through the two wire wheels 33 is passed around the top of the first driving wire wheel 46, the bottom of the floating wire wheel 48 and the top of the second driving wire wheel 47 in turn.

[0038] Reference Figure 1 and Figure 2When the winding machine is feeding the wire, the pay-off motor 6 starts and drives the pay-off shaft 5 to rotate, and the pay-off reel 2 rotates with the pay-off shaft 5 to realize automatic pay-off. According to different pay-off conditions and wire tension, the lifting cylinder 7 drives the lifting plate 31 and the pay-off reel 2 to move in the vertical direction to adjust the pay-off tension. The setting of the fixing ring 8, the clamping ring 9 and the clamping spring 10 realizes the clamping of the pay-off reel 2 and the lifting plate 31, so that the pay-off reel 2 can always abut against the top surface of the lifting plate 31. Since the metal wire is wound on the pay-off reel 2 in a certain pattern, the position of the two wire wheels 33 needs to correspond to the position of the metal wire on the pay-off reel 2. The adjusting motor 37 starts to drive the adjusting screw 38 to rotate, and the limit block 36 moves in the vertical direction under the limit guiding function of the limit rod 35 and the driving function of the adjusting screw 38. When the moving block 34 moves to contact the contact switch 39 above or below, the adjusting motor 37 receives an electrical signal from the contact switch 39, and the adjusting motor 37 reverses, and the adjusting screw 38 rotates in the opposite direction, so that the moving block 34 moves in the opposite direction. The setting of the contact switch 39 realizes that the wire wheel 33 corresponds to the wire-releasing position, which has the effect of guiding the wire-releasing direction and stabilizing the wire-releasing tension.

[0039] Reference Figure 2 and Figure 3 , the metal wire that has been paid out 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, thereby driving 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 applied by the floating wire wheel 48 to the metal wire is always kept constant, thereby stabilizing the pay-out tension and keeping the metal wire in a tensioned state. For metal wires of different specifications, the required pay-out tension is different. The floating wire wheel 48 is pulled in a direction away from the connecting cover 44, the end of the connecting shaft 13 is disengaged from the connecting hole 421, the connecting shaft 13 is moved to the connecting hole 421 of the corresponding counterweight block 42, the floating wire wheel 48 is released, and the connecting shaft 13 is embedded in the connecting hole 421 of the corresponding counterweight block 42 under the action of the anti-drop spring 14, thereby adjusting the tension of the metal wire.

[0040] Reference Figure 2 and Figure 3When the rotation speed of the first drive wheel 46 is greater than the rotation speed of the second drive wheel 47, the floating wheel 48 descends as the metal wire is released. When the floating wheel 48 descends to a position corresponding to the first induction switch 15, the first drive motor 11 receives an electrical signal, and the speed of the first drive motor 11 decreases. When the rotation speed of the second drive wheel 47 is greater than the rotation speed of the first drive wheel 46, the floating wheel 48 rises as the metal wire is released. When the floating wheel 48 descends to a position corresponding to the second induction switch 16, the second drive motor 12 receives an electrical signal, and the speed of the second drive motor 12 decreases. By setting the first induction switch 15 and the second induction switch 16, the speed adjustment of the first drive wheel 46 and the second drive wheel 47 is achieved, so that the driving speed of the floating wheel 48 is consistent before and after, further reducing the possibility of the metal wire breaking or loosening due to the inconsistent wire feeding speed before and after the wire feeding process.

[0041] The implementation principle of a wire feeding tension mechanism for a winding machine in Example 1 of the present application is as follows: when the winding machine is feeding the wire, the pay-off drum 2 rotates along with the pay-off shaft 5 to realize automatic pay-off. According to different pay-off conditions and wire tension, the lifting cylinder 7 drives the lifting plate 31 and the pay-off drum 2 to move in the vertical direction to adjust the pay-off tension. The setting of the contact switch 39 realizes the correspondence between the wire wheel 33 and the pay-off position, which has the effect of guiding the pay-off direction of the wire and stabilizing the pay-off tension.

[0042] The metal wire that is being paid out 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 block 42, so that the pressure applied by the floating wire wheel 48 to the metal wire is always kept constant, thereby achieving the stability of the pay-out tension. The setting of the first induction switch 15 and the second induction switch 16 makes the front and rear driving speeds of the floating wire wheel 48 consistent, further reducing the possibility of the metal wire breaking or loosening due to the inconsistent front and rear wire feeding speeds during the wire feeding process.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.
