A varnishing device specially used for producing enameled wire by mould method

Abstract

The invention discloses a special enamel coating device for mold-process enameled wire production, which comprises an integral enamel cylinder and a combined enameled wire mold, wherein each side surface of the integral enamel cylinder is shared and dual grooves are arranged in each line interval of gratings, a tubular adjustable enamel liquid overflow device is installed in the enamel cylinder and the combined enameled wire mold is detachably arranged in a production field. The special enamel coating device for mold-process enameled wire production has the beneficial effects that the dual-groove integral enamel cylinder can improve the use efficiency of the cross section of a drying oven for mold-process enameled wire production, the production efficiency is improved, and during the transformation of a felt-process enameled wire production method, the exertion of the production efficiency of the original machines is not influenced; and the combined mold can reduce reasonable process consumption during mold-process enameled wire production, the operation is more convenient to conduct, and process and equipment conditions are created for comprehensively popularizing the mold-process enameled wire production method which is an advanced production technology.

Description

technical field [0001] The invention relates to production process equipment for enameled wires, in particular to a paint coating device for producing enameled wires using a mold method. Background technique [0002] In the production process of enameled wire, the traditional method of coating enameled wire is mostly coated by felt method. Since the cross-section of the painted liquid is lip-shaped, it needs to rely on the surface tension of the paint liquid to round the process. Moreover, Felt has a process from dry to wet to wet during use, so the amount of paint is easy to change, and the quality of the finished enameled wire is difficult to control, which is likely to cause quality problems; but the advantage of the felt method is that it is easy to operate, especially This is especially true when converting formats. Since the 1980s, my country has introduced many advanced enameled wire production equipment from abroad, and most of them use the mold method to coat the e...

Problems solved by technology

The design idea is that the paint moving line does not move. During the production process, when the wire needs to be painted or stops painting, the paint supply grid changes its position, and the paint supply grid starts to supply paint when it is in an inclined position. The paint supply grid is at When the paint supply is stopped in the vertical position, the wire is in the same position from the beginning to the end. The disadvantage is that the structure of the paint tank is relatively complicated, and there is no single-line paint stop function. If the paint is stopped, all the inner 9 lines or the outer 3 lines must be stopped together.

In addition, the current paint vats are all independent, that is, each production head has its own independent paint vat, and each independent paint vat must be installed at a certain interval, so the paint painted by the traditional felt method When chartering a machine for mold painting transformation, it is necessary to reduce the number of production heads, and each side needs to reduce the number of production heads by 2, and the output is reduced by more than 20%. Therefore, the utilization rate of the cross-section of the enamelling oven is low, and the production efficiency is reduced.

[0004] In addition, the current enameled wire painting molds are all integral molds, and the wires must be re-threaded every time the car is driven or the specification is changed, which not only wastes man-hours, but also wastes a lot of valuable raw materials, and increases the labor intensity of the operators. It also increases the helper cost of enameled wire production
