Curved paper feeding humidifier for motor stator insulation paper

Abstract

The invention discloses a bend paper-feeding humidification device applied to motor stator insulation paper. The bend paper-feeding humidification device comprises a humidification chamber, wherein humidifiers are arranged at the top end and the bottom end in the humidification chamber; heaters are arranged on two opposite side walls in the humidification chamber in an up-and-down manner; one or more paper feeding devices are arranged in the humidification chamber; each automatic paper feeding device comprises a two-layer transmission belt which passes through a paper inlet and a paper outlet and a plurality of pressing rollers; each wo-layer transmission belt comprises a transmission belt sheet I in an upper layer, a transmission belt sheet II in a lower layer and a plurality of transmission shafts; one pressing roller is arranged between every two transmission shafts; each transmission belt sheet I is formed by two layer of belts; a magnetic stripe is pasted between the two layers of belts; the transmission belt sheet I winds between the plurality of transmission shafts and the plurality of pressing rollers to form a bend structure. The bend paper-feeding humidification device is good in tension and extension effects, uniform in humidification and long in humidification time; the paper breakage phenomenon of the insulation paper is solved; the bend paper-feeding humidification device is high in automation degree, stable in transmission process and high in working efficiency; the labor output can be alleviated.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a curved 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 cut off. ...

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.
