Automatic quantitative paint supply system

Abstract

The invention relates to an automatic quantitative paint supply system which comprises an enameling machine rack, wherein a painting groove rack holder is arranged on the enameling machine rack; multiple painting grooves are sequentially formed in the painting groove rack holder in parallel; to-be-painted wires are arranged in the painting grooves; a painting mold rack is arranged above the painting grooves; the automatic quantitative paint supply system is characterized in that a laser diameter measuring instrument is arranged on the enameling machine rack on one side above the painting grooves and is positioned between the painting grooves and the painting mold rack; a single wire paint supply pipe is arranged on each painting groove; one end of each single wire paint supply pipe is aligned with the to-be-painted wires, and the other end of each single wire paint supply pipe is connected with a paint storage box by virtue of a paint supply hose; and an electromagnetic valve is arranged between each paint supply hose and the paint storage box. According to the system disclosed by the invention, the condition that excessive paint returns to form a cycle can be avoided, and the balance between the paint supply quantity and the paint consumption is achieved.

Description

technical field [0001] The invention relates to an automatic quantitative paint supply system, in particular to a paint supply device in the enameled wire production process. Background technique [0002] The paint supply method of insulating varnish is an important part of the enameled wire processing technology. In recent years, in the production of acetal enamelled flat wire, the circular paint supply method is mostly adopted, that is, the paint storage boxes of each machine supply excessive paint to the wires, and the redundant The insulating varnish is returned to the paint storage tank through the return pipe, and then pumped to the wire by the varnish pump for reciprocating circulation. [0003] On the surface, the circular paint supply is automated, meets the painting requirements, improves the efficiency, and reduces the labor intensity of the operator, but this method has great disadvantages. During the continuous reciprocating cycle of the insulating varnish, the...

Problems solved by technology

During the continuous reciprocating cycle of the insulating varnish, the amount of varnish taken away by the wire per unit time is only equivalent to 10% of the total circulation. A large amount of solvent will volatilize into the air during the cyclic exposure of the insulating varnish, which not only changes the The viscosity affects the process parameters and pollutes the air in the painting room, and the longer the cycle is, the more obvious it is; because the air in the workshop contains dust that pollutes the insulating paint, it may be polluted by dust during the exposure process of the insulating paint cycle, which will affect the quality of the enameled wire; Insulating varnish is affected by various factors in the process of circulation and backflow, and overflow often occurs, polluting the guide wheel and painting room, and bringing hidden dangers to the quality of enameled wires; due to excessive varnish supply and large-scale reflow, a large amount of electric energy and insulating varnish are wasted
