Non-circulating paint supply device

Abstract

The invention relates to a non-circulating paint supply device. The device comprises painting rack bases mounted on two sides of a paint rack of an enamelling machine, and is characterized in that the painting rack is mounted on the painting rack bases; a plurality of painting grooves are arranged in sequence on the painting rack; upper insert plates are arranged on the one sides of the painting grooves; to be painted conducting wires are arranged between the upper insert plates and the painting rack; paint supply pipes are arranged on the other side of the painting grooves; one ends of the paint supply pipes face towards the conducting wires, and the other ends of the paint supply pipes are connected with a paint storage box through an externally connected paint supply flexible pipe; a paint supply valve is arranged on the externally connected supply flexible pipe; lower insert plates are arranged at the lower parts of the paint grooves respectively; clamping grooves are formed in the one sides of the lower insert plates; the shapes and sizes of the clamping grooves are matched with those of the conducting wires. According to the invention, the balance of the paint supply quantity and the paint consumption quantity is achieved by controlling the paint supply, so that the circulation caused by backflow of excessive paint is avoided.

Description

Technical field [0001] The invention relates to a non-circulating paint supply device, in particular to a paint supply device in the enameled wire production process. Background technique [0002] Insulating paint supply method is an important part of the enameled wire processing technology. In recent years, in the production of acetal enameled flat wire, the cyclic paint supply method is mostly used, that is, each machine separates the paint storage box and guides the wire to over-supply paint. The insulating paint returns to the paint storage tank through the return pipeline, and then is pumped to the wire by the paint to reciprocate. [0003] On the surface, it seems that the circulating paint supply is automated, which meets the painting requirements, improves the efficiency and reduces the labor intensity of the operator, but this method has great disadvantages. In the continuous reciprocating cycle of the insulating paint, the amount of paint carried by the wire per unit tim...

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
