Respectively driving type high-speed synchronous lacquer-coated machine

Abstract

The invention relates to a respectively drive high-speed synchronous enamel-coated machine, wherein, primarily various speed setting wheels are respectively driven by variable frequency motors; each variable frequency motor consists of an asynchronous machine, a frequency converter and a rotating speed encoder, can respectively and flexibly control the speed of different speed setting wheels, greatly improve the linear velocity of machines which can reach 1000 meters per minute and also greatly reduce the noise of mechanical drive; moreover, the high-tech technical proposals like high-speed pulse synchronous control, closed-loop control means for encoder feedback and so on are adopted between the motors, and the proportional relations of any two paths of pulses can be set randomly, thereby accurate isochronous or differential synchronous control of front speed setting wheels and rear speed setting wheels can be realized; the speed stability of the speed setting wheels and the speed synchronism of the front speed setting wheels and the rear speed setting wheels are guaranteed; moreover, the minor difference between front speed and rear speed can be finely tuned according to productrequirements. Furthermore, the invention can be conveniently combined with pre-and-post movable type ovens and constant tension wrap-ups into various enamel-coated machines and is particularly suitable for use in production of ultrathin enameled wires by metal wires with a diameter of 0.014 to 0.10 millimeter and even thinner metal wires.

Description

technical field [0001] The invention relates to an enameled wire enamelling machine, in particular to a thin or ultra-fine enameled wire enamelling machine which drives each fixed speed wheel separately and can maintain high-speed synchronization. Background technique [0002] At present, the thin or ultra-fine enameled wire enamelling machines used in the domestic market are driven by the same motor for the front fixed speed wheel and the rear fixed speed wheel installed at both ends of the oven, that is, two belts are installed on the same motor to connect the front and rear wheels respectively. The fixed speed wheel and the rear fixed speed wheel use the same motor to drive the front and rear two fixed speed wheels. Although it has the advantage of simple structure, this transmission method cannot adjust and ensure the enameled wire on the front and rear fixed speed wheels. The accuracy and stability of wire speed synchronization will increase the probability of wire brea...

Problems solved by technology

[0002] At present, the thin or ultra-fine enameled wire enamelling machines used in the domestic market are driven by the same motor for the front fixed speed wheel and the rear fixed speed wheel installed at both ends of the oven, that is, two belts are installed on the same motor to connect the front and rear wheels respectively. The fixed speed wheel and the rear fixed speed wheel use the same motor to drive the front and rear two fixed speed wheels. Although it has the advantage of simple structure, this transmission method cannot adjust and ensure the enameled wire on the front and rear fixed speed wheels. The accuracy and stability of wire speed synchronization will increase the probability of wire breakage; for thin or ultra-fine enameled wires, the situation is even more serious, and it also greatly limits the speed of the front and rear fixed wheels. Improvement, the maximum linear speed of the high-speed varnishing machine used in the domestic market can only reach 600 m / min, and there are disadvantages such as poor synchronization performance, slow rotation speed, low production efficiency, easy disconnection and large mechanical transmission noise.
