Double-roll paper-fed humidifier for motor stator insulation paper

Abstract

The invention discloses a dual-roller paper feeding type humidifying device for motor stator insulation paper. The dual-roller paper feeding type humidifying device comprises a humidifying chamber, wherein the top end and the bottom end of interior of the humidifying chamber are both provided with at least one humidifier, and two opposite side walls in the humidifying chamber are both provided with heaters arranged up and down; two opposite side surfaces of the humidifying chamber are respectively provided with a paper inlet and a paper outlet; the humidifying chamber is internally provided with at least one automatic paper feeding device; each automatic paper feeding device comprises a dual-layer conveying belt which passes through the paper inlet and the paper outlet, a first compression roller body arranged on the dual-layer conveying belt and a second compression roller body arranged between two layers of belts on the dual-layer conveying belt; transition holes with equal length are formed among the first roller body, the second roller body and the belt at the upper layer of the dual-layer conveying belt. The dual-roller paper feeding type humidifying device has the beneficial effects of uniformly moistening insulation paper, solving the paper breaking phenomenon of the insulation paper, being high in automation degree, reducing the labor output, increasing the economic benefit, and improving the working efficiency.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a double-roller paper-feeding humidifier for motor stator insulation paper. Background technique [0002] At present, the motor stator includes an iron core formed by laminating silicon steel sheets, a winding coil wound on the iron core, an upper insulating end plate located on the upper part of the stator, a lower insulating end plate located on the lower part of the stator, an upper insulating end plate and a lower insulating end The structure of the board is the same. A terminal shell is arranged above the upper insulating end plate, and the terminal shell and the winding coil are connected by wires. [0003] In order to prevent the iron core from contacting the coil and conduct electricity, the insulating paper is now passed through the wire slot of the iron core to the end of the insulating end plate, and then the excess part of the rear end of the insulating paper is cu...

AI Technical Summary

Problems solved by technology

The paper quality of the insulating paper is relatively hard. Before installing the insulating paper, the insulating paper has been folded into the same shape as the inner surface of the wire slot of the iron core. The coil passes through the wire slot where the insulating paper is placed and is wound on the connecting rib; When making electromagnetic wires, it is necessary to wrap bare copper wires with insulating paper to achieve the purpose of insulation. When using insulating paper to wrap bare copper wires, due to the high speed of wrapping and the different humidity of insulating paper, It is easy to break the paper. The existing technology mainly places the insulating paper directly in the basin-shaped container to humidify the surface of the paper by soaking it. The disadvantage of this method is that the degree of humidification of the humidification surface is uneven. There will also be a paper break when the humidity is too high, and the wrapped bare copper wire will also be oxidized; secondly, the humidification method of the existing technology has low work efficiency, more labor output, increased production costs, and reduced economic benefits.
