Description

Technical Field

[0001] This application relates to the technical field of enameled wire production, and in particular to a lead wire device for coating enameled wire. Background Technology

[0002] Currently, in the production of enameled wire, bare conductors need to be threaded through the coating device multiple times to achieve layered coating. Traditional manual threading methods are cumbersome and inefficient. To address this issue, Chinese utility model patent CN212230148U discloses a semi-automatic threading device before enameling. This device adds a threading wheel 2 between adjacent threading wheels of four conductor rollers, and winds a threading tape 22 around the same group of threading wheels 2, allowing the bare conductor end to be detachably fixed to the threading tape 22. The drive mechanism is located on the wire inlet side of the frame and includes a pressing and rotating assembly 4 and a fixed support assembly 5. The pressing and rotating assembly 4 has a rotating rod 43 with a pressing member 44 circumferentially arranged. The drive motor drives the rotating rod 43 to rotate via gear transmission, causing the pressing member 44 to rub against the outer circumference of the threading wheel 2, thereby driving the threading wheel 2 and the threading tape 22 to move, achieving semi-automatic traction of the bare conductor.

[0003] However, such lead-lead devices have the following problems in practical use: In a structure where multiple pressing members 44 drive multiple lead-lead wheels 2 simultaneously, if there are deviations in the machining accuracy or installation position of the pressing members 44, the contact pressure between each pressing member 44 and the lead-lead wheel 2 will be inconsistent. Some pressing members 44 may be in close contact with the lead-lead wheel 2, while others may have gaps or insufficient pressure, thus affecting the stability and reliability of the transmission. Utility Model Content

[0004] In order to solve the problem of poor transmission stability and reduced reliability caused by inconsistent contact pressure between multiple pressing parts and the lead wheel in existing enameled wire lead-leading devices, this application provides a lead-leading device for enameled wire coating.

[0005] The lead wire device for coating enameled wire provided in this application adopts the following technical solution:

[0006] A wire guiding device for enameling wire coating includes a frame, a drive assembly, a wire guide roller, a pressing assembly, and a driven shaft. The wire guide roller is connected to the frame, a wire guide bracket is connected to the wire guide roller, and a wire guide wheel is connected to the wire guide bracket. The axis of the wire guide wheel is parallel to the axis of the wire guide roller. The driven shaft is connected to the frame, and the drive assembly is connected to the frame and drives the driven shaft to rotate. The pressing assembly includes a pressing lever frame, a pulling member, and a pressing wheel. The pressing lever frame is connected to the driven shaft, and the pressing wheel is connected to the pressing lever frame. The axis of the pressing wheel is parallel to the axis of the wire guide wheel. One end of the pulling member is connected to the frame, and the other end of the pulling member is connected to the pressing lever frame. The driven shaft is connected to the drive assembly, which drives the pressing wheel to rotate.

[0007] By adopting the above technical solution, this solution sets up multiple pressing components, each of which includes a pressing lever, a pulling member, and a pressing wheel. The pulling member uses a tension spring to independently apply pressure to the lead-wire wheel for each pressing wheel. This design allows each pressing component to adaptively adjust the contact state between its pressing wheel and the corresponding lead-wire wheel, thereby effectively ensuring the consistency of pressure at multiple traction points and significantly improving the stability and reliability of the entire lead-wire device transmission.

[0008] Preferably, a connecting frame is connected to the pressing lever frame, and the pressing wheel is connected to the connecting frame via a mounting component.

[0009] By adopting the above technical solution, the design of the connecting frame and mounting components makes the installation of the pressure roller more convenient, facilitates maintenance and replacement, and maintains the alignment of the pressure roller and the lead roller.

[0010] Preferably, the mounting component includes a screw and a nut, the screw being connected to a connecting frame, the nut being used to position the screw on the connecting frame, the axis of the screw being parallel to the axis of the driven shaft, and the pressure wheel being sleeved on the screw.

[0011] By adopting the above technical solution, the screw and nut have a simple structure and are easy to install, ensuring that the pressure wheel and the lead wheel are aligned, thus enhancing the accuracy of transmission.

[0012] Preferably, the frame is provided with a connecting horizontal plate, the pressing lever is connected with a hanging piece, the connecting horizontal plate is connected with a hanging post, and the hanging post is located above the hanging piece;

[0013] One end of the pulling member is attached to the hanging plate, and the other end of the pulling member is attached to the hanging post.

[0014] By adopting the above technical solution, the hooking structure of the hook plate and the hook post makes the installation and tension adjustment of the pulling part easy, ensuring the stability of the position of the pressure lever frame, thereby maintaining the contact pressure between the pressure wheel and the lead wheel.

[0015] Preferably, a protective plate is connected to the connecting cross plate, and the protective plate is located on one side of the pulling member.

[0016] By adopting the above technical solution, the protective plate enhances the safety of the equipment. This protective plate effectively blocks the path of the pulling component in the event of accidental breakage or disengagement, providing safety protection for operators and reducing potential safety hazards.

[0017] Preferably, a wire drawing device for enameled wire coating further includes a clutch support shaft, which is rotatably connected to a frame. The axis of the clutch support shaft is parallel to the axis of the driven shaft, and the clutch support shaft is located above the driven shaft. A clutch block is rotatably connected to the clutch support shaft. A wrench is connected to a pressing lever frame, and the wrench abuts against the clutch block. A clutch groove is formed on the clutch block. When the wrench is in the clutch groove, the pressing wheel abuts against the wire drawing wheel. When the wrench is disengaged from the clutch groove, the pressing wheel disengages from the wire drawing wheel.

[0018] By adopting the above technical solution, the cooperation between the clutch support shaft and the clutch block provides a rapid clutch operation mechanism. Rotating the clutch block controls the separation and engagement of the pressure wheel and the lead wheel, eliminating the need to disassemble parts when replacing the lead belt or cleaning the wheel surface, significantly improving operation and maintenance efficiency.

[0019] Preferably, the drive assembly includes a drive motor, a drive gear, and a driven gear. The drive gear is connected to the output shaft of the drive motor, and the driven gear is connected to a driven shaft. The drive gear meshes with the driven gear.

[0020] By adopting the above technical solution, the drive motor transmits power through the meshing of the drive gear and the driven gear. This gear transmission method ensures smooth and reliable power transmission, guarantees the uniformity of the rotational speed of the driven shaft and the pressure wheel, and helps to maintain the stability of the lead wire speed.

[0021] Preferably, a first connecting gear is connected to the pressure wheel, and the driving component is a second connecting gear, wherein the first connecting gear meshes with the second connecting gear.

[0022] By adopting the above technical solution, the meshing of the second connecting gear and the first connecting gear transmits power from the driven shaft to the pressure wheel. This gear transmission avoids possible slippage, ensures the synchronicity and accuracy of the pressure wheel's rotation, and further improves the reliability of the lead wire.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This design incorporates multiple pressure-blocking components, each comprising a pressure-blocking lever, a pulling element, and a pressure-blocking wheel. The pulling element utilizes a tension spring to independently apply pressure to the lead-wire wheel for each pressure-blocking wheel. This design allows each pressure-blocking component to adaptively adjust the contact state between its pressure-blocking wheel and the corresponding lead-wire wheel, effectively ensuring the consistency of pressure at multiple traction points and significantly improving the stability and reliability of the entire lead-wire transmission system.

[0025] 2. The tension spring acts as a pulling element, providing continuous tension. The vertical section of the protective plate covers the extension range of the tension spring, reducing safety hazards by blocking its ejection path in the event that the tension spring accidentally detaches from the hook post or hook plate.

[0026] 3. The wrench of the pressure-operated frame rests against the clutch block under the action of the tension spring. Manually rotating the clutch block changes the position of its contact surface with the wrench, allowing precise control of the wrench's deflection angle. When the curved surface of the clutch block contacts the wrench, it restricts its deflection, separating the pressure roller from the lead wheel for easy replacement of the lead belt or cleaning and maintenance. When the notched surface of the clutch block contacts the wrench, the wrench is allowed to deflect fully under the action of the tension spring, ensuring reliable contact between the pressure roller and the lead wheel for lead-out operations.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a lead wire device for coating enameled wire, referring to... Figures 1-3 It includes a frame 1, a drive assembly 2, a painting device 3, a guide roller 4, a pressing assembly 6, and a clutch support shaft 7. The frame 1 is fixedly connected to the painting device 3, and the length direction of the frame 1 is parallel to the length direction of the painting device 3. A mounting bracket 11 is vertically fixedly connected to each end of the long shaft of the frame 1. (Refer to...) Figure 2 and Figure 4 A wire drawing device for coating enameled wire further includes a driven shaft 8. The drive assembly 2 includes a drive motor 21, a drive gear 22, and a driven gear 23. The drive motor 21 is fixedly connected to one of the mounting brackets 11, and the end of the output shaft of the drive motor 21 extends into the mounting bracket 11. The drive gear 22 is fixedly connected to the end of the output shaft of the drive motor 21. The driven shaft 8 is rotatably connected between two mounting brackets 11. The axis of the driven shaft 8 is parallel to the length direction of the frame 1. The end of the driven shaft 8 closest to the drive motor 21 extends into the mounting bracket 11, and the driven gear 23 is fixedly connected to one end of the driven shaft 8. The drive gear 22 on the output shaft of the drive motor 21 meshes with the driven gear 23 on the driven shaft 8.

[0037] Reference Figures 3-5 Multiple pressing components 6 are arranged along the axial direction on the driven shaft 8. In this embodiment, one pressing component 6 is used as an example for explanation. The pressing component 6 includes a pressing lever 61, a pulling member 63 and a pressing wheel 64. The pressing lever 61 is rotatably connected to the driven shaft 8 through a bearing. A connecting frame 611 is fixedly connected to the side of the pressing lever 61 near the frame 1. The pressing wheel 64 is rotatably connected to the connecting frame 611 through a mounting member 62.

[0038] Reference Figures 5-6The mounting component 62 includes a screw 621 and a nut 622. The screw 621 is inserted into the connecting frame 611 and fixedly connected to the connecting frame 611 by the nut 622. The pressure wheel 64 is sleeved on the screw 621, and a first connecting gear 641 is fixedly connected to the pressure wheel 64.

[0039] Reference Figure 2 , Figure 4 and Figure 6 A number of driving components, matching the number of pressing lever frames 61, are fixedly connected to the driven shaft 8. In this embodiment, the driving component is a second connecting gear 81, which is located inside the pressing lever frame 61 and meshes with a first connecting gear 641. A connecting horizontal plate 12 is fixedly connected between the two mounting brackets 11. The length direction of the connecting horizontal plate 12 is parallel to the axis of the driven shaft 8, and the connecting horizontal plate 12 is located on the side of the driven shaft 8 away from the frame 1.

[0040] Reference Figure 2 , Figure 5 and Figure 7 A hanging post 121 is fixedly connected to the side wall of the connecting horizontal plate 12 away from the driven shaft 8, and every two hanging posts 121 form a group, with the number of groups of hanging posts 121 matching the number of the pressing lever frame 61. Two hanging pieces 613 are fixedly connected to the lower end of the pressing lever frame 61. The length direction of the hanging pieces 613 is perpendicular to the length direction of the connecting horizontal plate 12, and the end of the hanging piece 613 away from the frame 1 is located directly below the hanging post 121. The end of the hanging piece 613 away from the frame 1 also has a hanging hole 6131. ​​In this embodiment, the pulling member 63 is vertically arranged, and the number of pulling members matches the number of hanging posts 121. The pulling member 63 is a tension spring; the lower end of the tension spring is hooked onto the hanging hole 6131 on the hanging piece 613, and the upper end of the tension spring is hooked onto the hanging post 121. A wrench 612 is vertically fixed to the upper end of the pressure lever 61. Under the action of the pulling member 63, the upper end of the wrench 612 will deflect towards the machine frame 1.

[0041] Reference Figure 2 and Figure 5 A protective plate 122 is fixedly connected to the connecting horizontal plate 12. The protective plate 122 is an inverted L-shaped plate. The horizontal section of the protective plate 122 is fixedly connected above the connecting horizontal plate 12, and the vertical section of the protective plate 122 is located on one side of the tension spring. The vertical section of the protective plate 122 covers the entire extension range of the tension spring. The protective plate 122 is used to block the ejection path of the tension spring in the event of accidental disengagement. The protective plate 122 has isolation grooves 1221 along its length, the number of which is the same as the number of pressure levers 61. The upper end of the lever 612 of the pressure lever 61 extends out from the isolation groove 1221.

[0042] Reference Figures 2-4The clutch support shaft 7 is rotatably connected between the two mounting brackets 11. The axis of the clutch support shaft 7 is parallel to the long axis of the driven shaft 8, and the clutch support shaft 7 is located above the driven shaft 8. The clutch support shaft 7 has clutch blocks 71 rotating on it, the same number as the number of abutting levers 61. Under the action of the pulling member 63, the side of the wrench 612 closest to the frame 1 will abut against the clutch block 71. In this embodiment, the clutch block 71 is a partial cylinder, that is, a portion of the original cylinder is cut off along a vertical surface to form a notch, which forms a clutch groove. When the wrench 612 abuts against the arc surface of the partial cylinder, the angle of deflection of the wrench 612 towards the frame 1 is greater than the angle of deflection of the wrench 612 against the notch surface of the partial cylinder.

[0043] Reference Figure 3 A support frame 14 is also fixedly connected to the frame 1. The length direction of the support frame 14 is parallel to the length direction of the frame 1, and the support frame 14 is located between the frame 1 and the clutch support shaft 7. A guide roller 4 is fixedly connected to the support frame 14. The axis of the guide roller 4 is parallel to the axis of the clutch support shaft 7. A number of lead wire brackets 41, the same as the number of pressure levers 61, are fixedly arranged on the guide roller 4 along its own axis. In this embodiment, one lead wire bracket 41 is used as an example. A lead wire wheel 411 is rotatably connected to one side wall of the lead wire bracket 41 facing the clutch support shaft 7. When the wrench 612 abuts against the notch surface of a portion of the cylinder, the pressure wheel 64 presses against the lead wire wheel 411. When the wrench 612 abuts against the arc surface of a portion of the cylinder, the pressure wheel 64 separates from the lead wire wheel 411.

[0044] Reference Figure 1 and Figure 3The function of the clutch block 71 is twofold: 1. To enable quick replacement of the lead wire strip 5: Each lead wire pulley 411 has a groove (not shown in the figure) on its outer circumference, and the lead wire strip 5 is hooked into the groove. The lead wire strip 5 will wear during use and needs to be replaced periodically. When the lead wire strip 5 reaches its replacement cycle, the operator can rotate the clutch block 71 in the corresponding position so that the arc surface of the clutch block 71 faces and abuts against the wrench 612 at the upper end of the pressure lever frame 61, thereby completely separating the pressure wheel 64 from the lead wire pulley 411. At this time, the operator can easily remove the worn old lead wire strip 5 from the groove of the lead wire pulley 411 and place the new lead wire strip 5 into the groove without disassembling any parts, significantly improving replacement efficiency. 2. To enable cleaning and maintenance of the pressure wheel 64 and the lead wire pulley 411: During the enameling process, paint or impurities may adhere to the contact surface of the pressure wheel 64 and the lead wire pulley 411 or into their grooves, affecting the traction effect. After the clutch block 71 is rotated to separate the pressure roller 64 from the lead roller 411, a clear operating space is formed between the two rollers. This allows the operator to easily and thoroughly clean the outer surface of the pressure roller 64 and the groove of the lead roller 411, removing accumulated paint residue or dirt, and ensuring the good operating condition of the equipment.

[0045] The implementation principle of the lead wire device for enameled wire coating in this embodiment is as follows: After the drive motor 21 starts, the output shaft drives the drive gear 22 to rotate. The drive gear 22 meshes with the driven gear 23, causing the driven shaft 8 to rotate. The second connecting gear 81 on the driven shaft 8 meshes with the first connecting gear 641 on the pressure wheel 64, thereby driving the pressure wheel 64 to rotate. The pulling member 63 is a tension spring, the upper end of which is attached to the hanging post 121 of the connecting horizontal plate 12, and the lower end is attached to the hanging hole 6131 of the hanging piece 613 of the pressure lever frame 61. Under the action of the tension spring, the wrench 612 on the pressure lever frame 61 deflects towards the frame 1. The clutch block 71 rotates on the clutch support shaft 7, and the clutch block 71 is designed as a partial cylinder. Rotating the clutch block 71 causes the wrench 612 to contact the notch surface of the clutch block 71, causing the pressure roller 64 to press against the lead wheel 411. Rotating the clutch block 71 causes the wrench 612 to contact the arc surface of the clutch block 71, causing the pressure roller 64 to separate from the lead wheel 411. When the pressure roller 64 and lead wheel 411 are in contact, the rotation of the pressure roller 64 drives the lead wheel 411 to rotate through friction, thereby pulling the bare wire end through the coating device 3, achieving a semi-automatic lead-leading process of layered coating. This application utilizes an independently configured pressure assembly 6 structure, where each pressure roller 64 is pressurized by a separate tension spring, allowing for adaptive adjustment of the contact state with the lead wheel 411, thus improving the stability and reliability of the transmission.

[0046] 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.
