Description

Technical Field

[0001] The invention relates to the technical field of wax coating devices, and in particular to a heating wax coating device and a method thereof for preventing a paper-wrapped conductor from being damaged. Background Art

[0002] Paper-wrapped composite conductors are made of bare copper flat wires wrapped with insulating paper, and then made of two or more composite outer-wrapped insulating papers; paper-wrapped transposed conductors are made of multiple enameled flat wires that are transposed and then wrapped with insulating paper. The outer-wrapped insulating paper of the conductor is mainly for insulation and heat dissipation, and can improve the overall strength of the conductor. During the production, transportation, winding, and operation of paper-wrapped conductors, friction, offset, and bumps will occur between the conductors. The surface of the insulating paper is relatively rough, so the friction coefficient is high. Once offset friction occurs between the conductors, it is easy to tear and wear the outer-wrapped insulating paper. Especially when the yield strength of the conductor is large, the outer-wrapped insulating paper may even be completely scratched off, and the copper conductor inside is damaged. There are hidden dangers in the insulation performance and overall strength. Therefore, a wax coating device is required to prevent the paper-wrapped conductor from being easily damaged during production, transportation, winding, and operation.

[0003] The existing patent (Announcement No.: CN106298099A) discloses a heating wax coating device for preventing paper-wrapped conductors from being damaged, including a heating and melting tank and a roller, wherein melted liquid paraffin is arranged in the heating and melting tank; the lower part of the roller contacts the liquid paraffin in the heating and melting tank, and the upper end of the roller contacts the paper-wrapped conductor. In the process of implementing this solution, it was found that the following problems existed in the prior art, which have not been well solved: when the device is used, the paraffin in the heating and melting tank is coated on the paper-wrapped conductor by the roller, but the temperature of the part of the paraffin in the heating and melting tank close to the heating mechanism is higher, and the temperature of the part away from the heating mechanism is lower, so the lower temperature paraffin is prone to partial solidification, which is easy to affect the device's wax coating treatment of the paper-wrapped conductor. Summary of the invention

[0004] In order to improve the problem that the above-mentioned device applies the paraffin in the heating and melting tank to the paper-wrapped conductor through a roller during use, however, the temperature of the paraffin in the heating and melting tank close to the heating mechanism is higher, while the temperature of the part away from the heating mechanism is lower. Therefore, the paraffin with a lower temperature is prone to partial solidification, which easily affects the wax coating process of the paper-wrapped conductor by the device. The present invention provides a heating wax coating device and a method for preventing the paper-wrapped conductor from being damaged.

When the cam plate 3 rotates, it is easy to drive the movable part 5 to move up and down.

[0027] Two vertical plates 4 are symmetrically arranged on the top of the hot wax box 1, and movable parts 5 are movably arranged on the opposite sides of the two vertical plates 4. The movable parts 5 are slidably matched with the outer wall of the cam plate 3. The outer wall of the vertical plate 4 is provided with a limiting groove 41, and a limiting block 42 is movably arranged in the limiting groove 41. The bottom surface of the limiting block 42 is connected to the inner bottom wall of the limiting groove 41 by setting a spring 43.
