Copper wire painting device for horizontal high-speed enamelling machine

Abstract

The invention belongs to the field of painting devices of enamelled wires, and particularly relates to a copper wire painting device for a horizontal high-speed enamelling machine. The copper wire painting device is provided with painting molds and a paint supplying device. The painting molds are used for carrying out multi-channel painting on each row wire, and the paint supplying device supplies paint liquid to the painting molds. The painting molds are horizontally arranged in parallel in the axial direction of mold holes in the molds, and containing boxes for containing paint liquid are arranged on wire inlets of the painting molds at the first painting working procedure and the last painting working procedure, each containing box is provided with a wire inlet end and a wire outlet end, copper wires to be painted pass through the wire inlet end and the wire outlet end of each containing box, the arrangement positions of the wire inlet end and the wire outlet end of each containing box are lower than the maximum containing height position of the paint liquid in the corresponding containing box, and the wire inlet end and the wire outlet end of each containing box are coaxial with the wire inlet of the corresponding painting mold. Due to the fact that the containing boxes are used as preparation painting units of the copper wires, painting stability of the enamelled wires at the painting technological position is effectively ensured, and the good film painting and coating effects of the enamelled wires are ensured.

Description

technical field [0001] The invention belongs to the field of enameled wire painting equipment, and in particular relates to a copper wire painting equipment for a horizontal high-speed enamelling machine used for maintaining a good painting effect during enameled wire processing. Background technique [0002] The enameled wire is made by annealing and softening the bare wire, and then going through several times of painting, baking and other processes. In the traditional enameled wire manufacturing process, mold coating is the most widely used coating process. Mold method painting uses a paint mold to form a fixed mold; when performing mold method painting, a paint outlet is arranged before the paint mold, and the paint outlet is located at the travel path of the copper wire to be painted, and the paint liquid is formed by the paint The inside of the box is pumped to the paint outlet through the paint pump. When the copper wire is traveling at high speed, it first passes t...

AI Technical Summary

Problems solved by technology

Due to the occasional paint pressure fluctuations when adjusting the paint supply valve of the paint pump, and even foreign matter such as some oxide scales may instantly block the paint conveying channel, often resulting in no paint or less paint in the paint conveying channel

Reflected at the paint outlet, there will be a situation where a certain section of copper wire is coated with too little paint or even cannot be coated smoothly, which will lead to unpainted copper wires or other poor coatings when this section of copper wire passes through the paint mould. Phenomenon

Moreover, since the above-mentioned paint pressure fluctuations and blockages occur instantaneously, the subsequent copper wires will be coated with paint normally, and the copper wires in this problematic section will immediately enter the next operation process, so the above-mentioned problems are extremely difficult to find, resulting in failure of subsequent products. The use is extremely dangerous, which will adversely affect the company's product reputation
