Low-stretching-amount double-traction enamelling machine

Abstract

The invention discloses a low-stretching-amount double-traction enameling machine which comprises a painting device, a rotary encoder, a wire, an oven, a first traction wheel, a first synchronous motor, a second traction wheel and a second synchronous motor, the painting device is arranged on one side of the oven, and the head end and the tail end of the wire are fixedly connected. A quenching and dedusting system for quenching and dedusting the wire is also arranged in the oven. The first traction wheel and the second traction wheel are controlled to run synchronously at the same speed, the wire running resistance of a wire is reduced, meanwhile, multiple times of automatic spraying and drying of a wire insulating layer are achieved, the thickness of the insulating layer on the surface of the superfine metal enameled wire is increased, the insulating capacity is enhanced, and the quenching and dedusting system is arranged so that the quality of the wire after the insulating layer is sprayed and dried is enhanced.

Description

technical field [0001] The invention relates to the technical field of enamelling machines, in particular to a low-drawing double-drawing enamelling machine. Background technique [0002] Enameled wire is a common electrical connection wire in electrical equipment. It is mainly composed of two parts: a wire and an insulating layer. Common wires include copper wires and copper alloy wires. The insulating layer is formed after painting and baking on the surface of the wires. The wire forming the insulation layer is also called "bare wire". The production of enameled wire is usually carried out on an enameling machine, which generally includes the steps of setting out, annealing, painting, baking, cooling, lubricating and winding; [0003] Such as figure 1 As shown, the existing enamelling machine includes a paint applicator a, an oven b, a wire c, a guide wheel d and a traction wheel e; the existing line system of enameled wire production equipment is composed of a traction w...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 As shown, the existing enamelling machine includes a paint applicator a, an oven b, a wire c, a guide wheel d and a traction wheel e; the existing line system of enameled wire production equipment is composed of a traction wheel e at both ends of the oven outlet. It is composed of one or more sets of guide wheels d, the traction wheel e provides the line power (drive wheel), and the guide wheel d is a passive wheel. This combination is simple in structure, easy to control, and can use the passive resistance of guide wheel d to make The row wire is kept tight and straightened in the oven b to avoid sagging, but this mature structure will thin or even break the enameled wire due to the resistance of the guide wheel c when producing fine wire, especially the metal wire with low tensile strength It is even more difficult to produce normally, especially the aluminum wire in the production of enameled wire is more likely to be stretched, thus being thinned or even broken;

[0004] In addition, in the process of spraying and drying the wires for many times, it is necessary to thread them, fix the head and tail ends of the wires, and then adjust the tightness of the wires. The threading is slow and not convenient enough, and if the wire and the traction wheel e are loose, the traction wheel e cannot drive the wire to rotate. There is no lead wire structure and tension adjustment structure in the existing equipment, and the wire is easily exposed to the outside air. Attached dust affects the quality of the product when it is sprayed with insulating paint;
