Description

Technical Field

[0001] This utility model relates to the field of transformer winding processing technology, specifically a baking device for transformer winding processing. Background Technology

[0002] In the manufacturing process of transformer windings, baking is a crucial step to ensure the insulation performance, mechanical strength, and service life of the windings. After winding is completed, a certain amount of moisture and volatiles usually remain inside the winding, and the insulation layer needs to be cured and shaped through baking.

[0003] The inventors discovered that at least the following problems remain unresolved in existing technologies: While traditional baking devices achieve continuous conveying to some extent, most employ a single-temperature zone design. The windings, upon entering the baking channel, directly contact the high-temperature environment, making them prone to internal stress due to excessive instantaneous temperature differences, potentially leading to insulation layer cracking and other hazards. Furthermore, some conveying devices lack a winding rotation mechanism, causing the windings to maintain a fixed posture throughout the conveying process. This single contact angle with the heat source further exacerbates uneven heating, resulting in inconsistent curing degrees across different parts of the windings.

[0004] Therefore, we propose a baking device for transformer winding processing, which can solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a baking device for processing transformer windings, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a baking device for processing transformer windings, comprising a conveying track and an electric heating tube, a baking channel fixedly connected above the conveying track, a conveying plate horizontally arranged on the upper surface of the conveying track, electric rollers rotatably connected to both sides of the upper surface of the conveying track, the bottom side of the conveying plate being rotatably connected to the electric rollers, a baking tray arranged in the middle of the upper surface of the conveying plate, and a driving mechanism for driving the baking tray to rotate.

[0007] As an optional solution to the technical solution of this application, the driving mechanism includes a gear and a rack for driving the baking tray to rotate. A driving rod is vertically fixedly installed in the middle of the bottom side of the baking tray. The end of the driving rod away from the baking tray is fixedly connected to the middle of the upper surface of the gear. The rack meshes with the gear.

[0008] As an optional solution to the technical solution of this application, the heating tubes are installed at equal intervals from front to back on both sides of the inner wall of the baking channel.

[0009] As an optional solution to the technical solution of this application, the drive rod is rotatably connected to the middle of the conveyor plate through a bearing, and the size of the baking tray matches that of the baking channel.

[0010] As an optional solution to the technical solution of this application, a fixing strip is horizontally fixedly installed on the inner wall of the bottom end of the conveying track, and the rack is horizontally welded to the side of the fixing strip near the gear.

[0011] As an optional solution to the technical solution of this application, a limiting groove is horizontally formed on the lower surface of the conveyor plate, and the top end of the fixing strip is slidably connected to the limiting groove on the bottom side of the conveyor plate.

[0012] Compared with existing technologies, the advantages of this invention are as follows: By driving the conveyor plate along the conveyor track with electric rollers, the windings can be smoothly fed into the baking channel, achieving automated conveying. The heating elements equidistantly installed on both sides of the baking channel's inner walls employ a gradient heating design, with the heating temperature increasing sequentially from front to back, ensuring the windings are gradually heated during conveying and avoiding localized overheating or uneven heating. Through a gear and rack drive mechanism, as the conveyor plate moves, the rack fixed to the conveyor track meshes with the gear on the bottom side of the baking tray, driving the drive rod and baking tray to rotate synchronously, ensuring the windings are in full contact with the heat source and further improving heating uniformity.

[0017] Please see Figures 1-2This utility model provides a technical solution: a baking device for processing transformer windings, including a conveying track 1 and an electric heating tube 14. A baking channel 11 is fixedly connected above the conveying track 1. The electric heating tubes 14 are installed at equal intervals from front to back on both sides of the inner wall of the baking channel 11. A conveying plate 12 is horizontally arranged on the upper surface of the conveying track 1. Electric rollers 13 are rotatably connected to both sides of the upper surface of the conveying track 1. The bottom side of the conveying plate 12 is rolledly connected to the electric rollers 13. A baking tray 15 is arranged in the middle of the upper surface of the conveying plate 12.

[0018] In this technical solution, the winding to be baked is placed on the upper surface of the baking tray 15. The electric roller 13 is rotated by a corresponding controller, causing the conveyor plate 12 to move above the conveyor track 1. This further transports the winding from the upper surface of the baking tray 15 to the inner side of the baking channel 11. Since the heating elements 14 are equidistantly installed on both sides of the inner wall of the baking channel 11 from front to back, and the heating temperature of the heating elements 14 increases sequentially from front to back, the winding is heated evenly, further improving the baking effect. It should be noted that the baking time of the winding can be controlled by adjusting the moving speed of the conveyor plate 12.

[0019] In this embodiment, a drive mechanism for driving the baking tray 15 to rotate is also included. The drive mechanism includes a gear 21 and a rack 23 for driving the baking tray 15 to rotate. A drive rod 2 is vertically fixedly installed in the middle of the bottom side of the baking tray 15. The end of the drive rod 2 away from the baking tray 15 is fixedly connected to the middle of the upper surface of the gear 21. The drive rod 2 is rotatably connected to the middle of the conveyor plate 12 through a bearing. The baking tray 15 is matched with the size of the baking channel 11. A fixing strip 22 is horizontally fixedly installed on the inner wall of the bottom end of the conveyor track 1. The rack 23 is horizontally welded to the side of the fixing strip 22 near the gear 21, and the rack 23 meshes with the gear 21.

[0020] In this technical solution, during the movement of the electric roller 13 driving the conveyor plate 12, the drive rod 2 can drive the gear 21 on the bottom side of the baking tray 15 to move. Since the gear 21 meshes with the rack 23 at the bottom of the conveyor track 1, during the further movement of the conveyor plate 12, the rack 23 can drive the gear 21 to rotate, and the drive rod 2 can drive the baking tray 15 to rotate on the upper surface of the conveyor plate 12, further improving the baking effect of the upper surface of the baking tray 15.

[0021] In this embodiment, a limiting groove 24 is horizontally formed on the lower surface of the conveyor plate 12, and the top end of the fixing strip 22 is slidably connected to the limiting groove 24 on the bottom side of the conveyor plate 12.

[0022] In this technical solution, by sliding the top of the fixing strip 22 to the limiting groove 24 on the bottom side of the conveying plate 12, the movement stability of the conveying plate 12 can be improved, and the meshing accuracy of the rack 23 and the gear 21 can be further improved, thereby improving the rotational stability of the baking tray 15 during the movement of the conveying plate 12.

[0023] When using a baking apparatus for transformer winding processing, the winding to be baked is placed on the upper surface of the baking tray 15. The electric roller 13 is rotated by the corresponding controller, which enables the conveyor plate 12 to move above the conveyor track 1, further conveying the winding on the upper surface of the baking tray 15 to the inner side of the baking channel 11. Since the heating tubes 14 are installed at equal intervals from front to back on both sides of the inner wall of the baking channel 11, and the heating temperature of the heating tubes 14 increases sequentially from front to back, the winding can be heated evenly. At the same time, the rack 23 at the bottom of the conveyor track 1 meshes with the gear 21 on the bottom side of the baking tray 15. During the movement of the conveyor plate 12, the rack 23 can drive the gear 21 to rotate, which can drive the baking tray 15 to rotate on the upper surface of the conveyor plate 12 via the drive rod 2, further improving the baking effect of the winding on the upper surface of the baking tray 15.
