Description

Technical Field

[0001] This utility model relates to the field of conductor body production technology, and in particular to a thin-film wire coating production equipment. Background Technology

[0002] Film-wrapped wire is made by wrapping a film tape (such as polyimide) coated with a high-temperature resistant adhesive (such as polyvinyl fluoride propylene) around a conductor. After heating, the film tape is bonded and sealed to form a continuous insulation layer. It has the advantages of high temperature resistance, radiation resistance, sealing performance, good electrical performance and wear resistance. In order to improve electrical performance and better withstand overvoltage and overload, a film is usually wrapped around the enameled wire in the existing technology. This combined insulation method puts higher requirements on the enamel coating effect of the enameled wire.

[0003] Chinese utility model patent CN216419954U discloses a coating device for thin-film wrapped wires, including a wire body and a coating assembly. The coating assembly includes a housing, a coating component, a coating box, a drive component, and a guide component. The coating component includes pressure rollers and inclined grooves. Two pressure rollers are provided, and each pressure roller has a felt tube fixedly fitted on its outer circumference. Through holes are evenly distributed at the position where each pressure roller and the felt tube are in contact. The drive component is fixedly connected to the housing and to one of the pressure rollers. The wire body is movably pressed against the two felt tubes. The inner cavities of the two pressure rollers are filled with coating material. Under the capillary siphon characteristic of the felt tubes, the coating material in the inner cavities of the pressure rollers is drawn out through the through holes. The drive component drives one pressure roller to rotate, and through the friction of the felt tube, it drives the other felt tube to rotate, thus applying the coating material to the wire body.

[0004] Regarding the aforementioned technology, the inventors believe it suffers from the following drawbacks: The device uses two felt tubes to press the conductor body together, bringing the surfaces of the felt tubes into contact with the conductor body. Paint is then applied to the surface of the conductor body in the contact area. However, the tight clamping of the two felt tubes makes it inconvenient for workers to pass the conductor head through them. Furthermore, the clamping action between the two felt tubes and the conductor body creates an arc-shaped contact area, resulting in a larger contact area on the sides of the conductor body and a smaller, or even nonexistent, contact area at the top and bottom. This leads to uneven paint application on the top or bottom of the conductor body, or in some cases, the paint cannot be applied to these areas at all. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a thin film wrapping wire production equipment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a thin film wire coating production device, comprising a mounting frame and a paint supply assembly, wherein two inclined sliding rods are slidably arranged on the upper part of one side of the mounting frame, and a mounting seat is provided at one end of the two sliding rods located inside the mounting frame; a sliding unit for driving the mounting seat to slide is provided on the mounting frame; a paint coating assembly is respectively provided on the mounting seat and the mounting frame; the paint coating assembly includes an L-shaped plate, and a first mounting seat is provided on the horizontal section of the L-shaped plate; a first rotating part is horizontally rotatably provided on the first mounting seat. The L-shaped plate has a second mounting base on its vertical section, and a second rotating tube is rotatably mounted on the second mounting base. The axis of the first rotating tube is perpendicular to the axis of the second rotating tube. The L-shaped plate has a drive unit that drives the first and second rotating tubes to rotate synchronously. Felt cylinders are fixedly sleeved on the outside of both the first and second rotating tubes. Several through holes are circumferentially opened on the tubes connecting the first and second rotating tubes to the felt cylinders. A rotary joint is provided at one end of both the first and second rotating tubes, and the end of the rotary joint is connected to the paint supply assembly.

[0007] By adopting the above technical solution, an installation frame, sliding unit, paint supply assembly, mounting base, and paint coating assembly are set up. The wire body is passed through the middle of the installation frame, and its lower part contacts the felt tube on the first rotating tube of the lower paint coating assembly. Then, one side of its wire body contacts the felt tube on the second rotating tube of the lower paint coating assembly. Subsequently, the sliding unit drives the mounting base to slide, causing the upper paint coating assembly to move closer to the lower paint coating assembly, so that the felt tubes on the first rotating tubes of the two paint coating assemblies contact each other, and the felt tubes on the second rotating tubes of the two paint coating assemblies contact each other, pressing the wire body tightly. In the initial state, there is a certain distance between the two paint coating assemblies to facilitate the worker to pass the wire body through. The drive unit drives the first rotating tube, the second rotating tube, and the felt tube to rotate, thus conveying the conductor body. At the same time, the paint supply assembly feeds paint into the rotary joint, the first rotating tube, and the second rotating tube. The paint then flows through the through hole onto the felt tube and is finally applied to the surface of the conductor body. The felt tube on the first rotating tube applies paint to the upper and lower surfaces of the conductor body, while the felt tube on the second rotating tube applies paint to the left and right surfaces of the conductor body, ensuring uniform application.

[0008] Furthermore, the paint supply assembly includes a paint box mounted on a frame, a feeding pump at the bottom of the paint box, an inlet of the feeding pump connected to the bottom of the paint box, and a discharge pipe at the outlet, with four feeding pipes connected to the discharge pipe and each feeding pipe connected to a corresponding rotary joint.

[0009] By adopting the above technical solution, a paint box, a feeding pump, a discharge pipe, and a feeding pipe are set up. The feeding pump pumps the paint in the paint box into the discharge pipe, and then flows through the four feeding pipes to the two first rotating pipes and the two second rotating pipes respectively.

[0010] Furthermore, two first mounting plates are spaced apart on the first mounting base, and the first rotating tube is rotatably disposed between the two first mounting plates.

[0011] Furthermore, two second mounting plates are spaced apart on the second mounting base, and the second rotating tube is rotatably disposed between the two second mounting plates.

[0012] Furthermore, the drive unit includes a drive motor vertically mounted on an L-shaped plate. A first gear and a first bevel gear are fixedly sleeved on the output shaft of the drive motor. A rotating shaft is horizontally rotatably mounted on the second mounting base. A first pulley and a second bevel gear are fixedly sleeved on the rotating shaft. The second bevel gear meshes with the first bevel gear. One end of the first rotating tube passes through the first mounting plate and is fixedly sleeved with a second pulley. The second pulley is connected to the first pulley via a transmission belt. A rotating shaft is vertically rotatably mounted on one of the second mounting plates. A second gear is fixedly sleeved on the rotating shaft. The second gear meshes with the first gear. One end of the second rotating tube passes through the second mounting plate and is fixedly sleeved with a third gear. The third gear meshes with the second gear.

[0013] By adopting the above technical solution, the drive motor drives the first gear and the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear, the first pulley, and the rotating shaft to rotate. Since the second pulley is connected to the first pulley through a transmission belt, the rotation of the second pulley drives the first rotating tube to rotate. The rotation of the first gear drives the second gear to rotate, thereby driving the third gear and the second rotating tube to rotate.

[0014] Furthermore, the sliding unit includes a drive cylinder mounted on the frame, the piston rod of the drive cylinder passing through the mounting frame and connected to the mounting base, and the drive cylinder being parallel to the slide rod.

[0015] By adopting the above technical solution, a drive cylinder is set up, which drives the mounting base to slide.

[0016] Furthermore, one of the first mounting plates is provided with a first connecting frame, which is connected to the outer surface of the rotary joint on the first rotating tube away from the first rotating tube. The L-shaped plate is provided with a second connecting frame, which is connected to the outer surface of the rotary joint on the second rotating tube away from the second rotating tube.

[0017] By adopting the above technical solution, a first connecting frame and a second connecting frame are set up to restrict the side of each rotary joint away from the first rotating tube and the second rotating tube, thereby ensuring the stability of the feeding tube.

[0018] In summary, this utility model has the following beneficial effects: It includes an installation frame, a sliding unit, a paint supply assembly, a mounting base, and a paint coating assembly. The wire body passes through the middle of the installation frame, and its lower part contacts the felt tube on the first rotating tube of the lower paint coating assembly. Then, one side of the wire body contacts the felt tube on the second rotating tube of the lower paint coating assembly. Subsequently, the sliding unit drives the mounting base to slide, causing the upper paint coating assembly to move closer to the lower paint coating assembly, so that the felt tubes on the first rotating tubes of both paint coating assemblies contact, and the felt tubes on the second rotating tubes of both paint coating assemblies contact, thus pressing the wire body tightly. Initially, there is a certain distance between the two paint coating assemblies, facilitating the worker to pass the wire body through. The drive unit drives the first rotating tube, the second rotating tube, and the felt tube to rotate, thus conveying the conductor body. At the same time, the paint supply assembly feeds paint into the rotary joint, the first rotating tube, and the second rotating tube. The paint then flows through the through hole onto the felt tube and is finally applied to the surface of the conductor body. The felt tube on the first rotating tube applies paint to the upper and lower surfaces of the conductor body, while the felt tube on the second rotating tube applies paint to the left and right surfaces of the conductor body, ensuring uniform application.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-6 As shown in the illustration, this application discloses a thin-film wire coating production device, including a mounting frame 10, a paint supply assembly 20, a sliding unit 40, a mounting base 31, and a painting assembly 50. The paint supply assembly 20 is mounted on the mounting frame 10, which is generally square. Two inclined sliding rods 30 are slidably mounted on the upper part of one side of the mounting frame 10, with the length direction of the sliding rods 30 aligned with the length direction of one diagonal of the square frame. The two sliding rods 30 share a mounting base 31 at one end within the mounting frame 10. The sliding unit 40 is mounted on the mounting frame 10 and is used to drive the mounting base 31 to slide. The driving unit 40 includes a driving cylinder 41 mounted on the frame. The piston rod of the driving cylinder 41 passes through the mounting frame 10 and connects to the mounting base 31. The driving cylinder 41 is parallel to the sliding rods 30 and drives the mounting base 31 to slide. There are two painting assemblies 50, one mounted on the mounting base 31 and the other located in the lower part of the mounting frame 10 away from the mounting base 31. In the initial state, there is a certain distance between the two painting components 50, which makes it easy for the staff to pass the wire body through.

[0028] Specifically, the painting assembly 50 includes an L-shaped plate 51. A first mounting base 52 is provided on the horizontal section of the L-shaped plate 51. A first rotating tube 53 is horizontally rotatably mounted on the first mounting base 52. A second mounting base 54 is provided on the vertical section of the L-shaped plate 51. A second rotating tube 55 is vertically rotatably mounted on the second mounting base 54. The axis of the first rotating tube 53 is perpendicular to the axis of the second rotating tube 55. A drive unit 60 is provided on the L-shaped plate 51 to drive the first rotating tube 53 and the second rotating tube 55 to rotate synchronously. Felt tubes 56 are fixedly sleeved on the outside of the first rotating tube 53 and the second rotating tube 55. Several through holes 57 are circumferentially opened on the tubes of the first rotating tube 53 and the second rotating tube 55 that connect to the felt tubes 56. One end of the first rotating tube 53 and the second rotating tube 55 is closed, and the other end is provided with a rotary joint 58. The end of the rotary joint 58 is connected to the paint supply assembly 20. Pass the wire body through the middle of the mounting frame 10, and make its lower part contact the felt tube 56 on the first rotating tube 53 of the lower painting assembly 50, and then make one side of it contact the felt tube 56 on the second rotating tube 55 of the lower painting assembly 50. Subsequently, the mounting base 31 is driven to slide by the sliding unit 40, causing the upper painting assembly 50 to move closer to the lower painting assembly 50, so that the felt tubes 56 on the first rotating tubes 53 and the second rotating tubes 55 of the two painting assemblies 50 come into contact, pressing the wire body together. The driving unit 60 drives the first rotating tubes 53, the second rotating tubes 55, and the felt tubes 56 to rotate, conveying the wire body. At the same time, the paint supply assembly 20 feeds paint into the rotary joint 58, the first rotating tubes 53, and the second rotating tubes 55, and then flows through the through hole 57 onto the felt tubes 56, and is finally coated on the surface of the wire body. The felt tubes 56 on the first rotating tubes 53 coat the upper and lower surfaces of the wire body, and the felt tubes 56 on the second rotating tubes 55 coat the left and right surfaces of the wire body, ensuring uniform coating.

[0029] During setup, two first mounting plates 521 are spaced apart on the first mounting base 52, and the first rotating tube 53 is rotatably positioned between the two first mounting plates 521 to ensure stable rotation of the first rotating tube 53. Two second mounting plates 541 are spaced apart on the second mounting base 54, and the second rotating tube 55 is rotatably positioned between the two second mounting plates 541 to ensure stable rotation of the second rotating tube 55. The drive unit 60 includes a drive motor 61 vertically mounted on an L-shaped plate 51. A first gear 62 and a first bevel gear 63 are fixedly mounted on the output shaft of the drive motor 61. A rotating shaft 64 is horizontally rotatably mounted on a second mounting base 54. A first pulley 65 and a second bevel gear 66 are fixedly mounted on the rotating shaft 64. The second bevel gear 66 meshes with the first bevel gear 63. One end of the first rotating tube 53 passes through the first mounting plate 521 and is fixedly mounted with a second pulley 67. The second pulley 67 is connected to the first pulley 65 through a transmission belt 671. The drive motor 61 drives the first bevel gear 63 to rotate. The rotation of the first bevel gear 63 drives the second bevel gear 66, the first pulley 65, and the rotating shaft 64 to rotate. Since the second pulley 67 is connected to the first pulley 65 through the transmission belt 671, the rotation of the second pulley 67 drives the first rotating tube 53 to rotate. A rotating shaft 68 is vertically rotatably mounted on one of the second mounting plates 541. A second gear 681 is fixedly sleeved on the rotating shaft 68. The second gear 681 meshes with the first gear 62. One end of the second rotating tube 55 passes through the second mounting plate 541 and is fixedly sleeved with a third gear 69. The third gear 69 meshes with the second gear 681. The drive motor 61 drives the first gear 62 to rotate. The rotation of the first gear 62 drives the second gear 681 to rotate, thereby driving the third gear 69 and the second rotating tube 55 to rotate.

[0030] In a specific configuration, the paint supply assembly 20 includes a paint box 21 mounted on a frame. A feed pump 22 is located at the bottom of the paint box 21. The feed pump 22 has an inlet connected to the bottom of the paint box 21 and an outlet pipe 23 connected to its outlet. Four feed pipes 24 are connected to the outlet pipe 23, and each feed pipe 24 is connected to a corresponding rotary joint 58. The feed pump 22 pumps the paint from the paint box 21 into the outlet pipe 23, and then the paint flows through the four feed pipes 24 to two first rotary pipes 53 and two second rotary pipes 55, respectively. The rotary joints 58 connect the feed pipes 24 to the first rotary pipes 53 or the second rotary pipes 55, ensuring that the rotation of the first rotary pipes 53 or the second rotary pipes 55 does not affect the feed pipes 24. One of the first mounting plates 521 is provided with a first connecting frame 70, which is connected to the outer surface of the rotary joint 58 on the first rotating tube 53 away from the first rotating tube 53. The L-shaped plate 51 is provided with a second connecting frame 71, which is connected to the outer surface of the rotary joint 58 on the second rotating tube 55 away from the second rotating tube 55. The second connecting frame 71 restricts the side of each rotary joint 58 away from the first rotating tube 53 and the second rotating tube 55 to ensure the stability of the feeding tube 24.

[0031] The operating principle of the film-coated wire production equipment in this embodiment is as follows: The wire body is passed through the middle of the mounting frame 10, and its lower part contacts the felt tube 56 on the first rotating tube 53 of the lower coating assembly 50. Then, one side of the wire body contacts the felt tube 56 on the second rotating tube 55 of the lower coating assembly 50. Subsequently, the drive cylinder 41 is activated to drive the mounting base 31 to move, so that the upper coating assembly 50 moves closer to the lower coating assembly 50, so that the felt tubes 56 on the first rotating tubes 53 of the two coating assemblies 50 contact, and the felt tubes 56 on the second rotating tubes 55 of the two coating assemblies 50 contact, thus pressing the wire body together. The feed pump 22 is activated, and the feed pump 22 pumps the paint in the paint box 21 into the discharge pipe 23, and then flows through the four feed pipes 24 to the two first rotating tubes 53 and the two second rotating tubes 55 respectively, and flows through the through hole 57 to the felt tube 56. The drive motor 61 is started, driving the first gear 62 and the first bevel gear 63 to rotate. The rotation of the first bevel gear 63 drives the second bevel gear 66, the first pulley 65, the rotating shaft 64, the second pulley 67, and the first rotating tube 53 to rotate. The rotation of the first gear 62 drives the second gear 681, the third gear 69, and the second rotating tube 55 to rotate. This causes the four felt tubes 56 to rotate, conveying the conductor body. The paint is applied to the surface of the conductor body by the felt tubes 56. The felt tubes 56 on the first rotating tube 53 apply paint to the top and bottom surfaces of the conductor body, while the felt tubes 56 on the second rotating tube 55 apply paint to the left and right surfaces of the conductor body, ensuring even application.
