Embodiment

[0015] Such as figure 1 As shown, a new production device for anti-corona belts for generators includes a feeding device, a dipping tank 4, a rolling device 6, a drying box 7, a shearing device 8 and a winding device 9.

[0016] The feeding device includes a rolled gray cloth 1 and a power motor (not shown in the figure) for rotating and discharging the gray cloth 1; a lower shaft 2 and an upper shaft are respectively arranged below and above the discharging direction of the gray cloth 1 3. After the gray cloth 1 is pulled by the lower rotating shaft 2 and the upper rotating shaft 3, the texture and void distribution of the gray cloth 1 can be made more uniform, which is beneficial to the infiltration of the anti-corona paint impregnating liquid.

[0017] The gray cloth 1 turns to enter the dipping tank 4 after passing through the upper rotating shaft 3; a rolling device 6 for removing excess anti-corona paint impregnating liquid is arranged above the dipping tank 4, and the r...

Abstract

The invention discloses a novel production device for a generator corona-proof belt. The novel production device comprises a feeding device, a dipping groove, a milling device, a drying device, a cutting device and a rolling device. Grey cloth after pull is dipped and is then cut and subpackaged after milling and drying. The novel production device is advantaged in that, (1), the grey cloth after pull is dipped, textures and gaps are uniformly distributed, thickness of the corona-proof belt after dipping, drying and molding is uniform, after wrapping, the surface of workpieces has no obvious unevenness; (2), the grey cloth can be cut and subpackaged after drying, and secondary processing process is avoided; the grey cloth can be driven to realize circulation through two power motors till the grey cloth is subpackaged into finished products; (3), the novel production device is simple and convenient to operate, realizes energy saving and high efficiency, reduces production cost and is suitable for industrialized mass production.

Description

technical field [0001] The invention relates to the technical field of anti-corona belts, in particular to a novel production device for anti-corona belts for generators. Background technique [0002] At present, the high-resistance anti-corona belts for generators produced in China are mostly made of alkali-free glass ribbons, polyester interwoven belts, etc., coated with high-resistance anti-corona paint. Due to the double-sided locking of the material used for the base material, the thickness of the high-resistance anti-corona tape is uneven, resulting in uneven surface after the electrical workpiece is wrapped, and the corona inception voltage is low after dipping, the final product is unqualified, and this process consumes a lot of power , low efficiency and high cost. [0003] Therefore, optimizing the production process and devices, preparing high-resistance anti-corona belts with uniform thickness, improving efficiency and reducing costs have become one of the urgen...
