Improved paint cylinder structure

Abstract

The invention provides an improved paint cylinder structure which can effectively reduce the waste of the insulating paint in a painting process, lowers the cost of raw materials, simultaneously reduces the influence of external temperature and humidity on the performance of the insulating paint, and ensures the production quality of lacquered wires. The improved paint cylinder structure comprises a paint groove, a felt, a felt pressing plate and a waste paint groove, wherein the painted surface of the paint groove is formed by the felt and the felt pressing plate, the felt is tightly pressedby the felt pressing plate, a U-shaped notch is formed on the felt pressing plate, and the waste paint groove is positioned at the lower part of the paint groove. The invention is characterized in that an oblique baffle plate is installed in the paint groove, the paint groove is divided into an upper part and a lower part by the oblique baffle plate, an insulating paint containing groove is formed at the upper part of the paint groove, and an insulating paint thermostat is installed at the lower part of the paint groove.

Description

technical field [0001] The invention relates to the field of enameled wire processing equipment, in particular to an improved paint vat structure. Background technique [0002] At present, the painting process of enameled wire production is mostly completed by vertical enamelling machine, which mainly adopts felt method or mold method. The mold controls the amount of paint, and the excess insulating paint returns to the paint tank and paints in a cycle as the wire continues to run upwards. The previous paint vat structure includes a paint tank 1, a felt 2, a felt pressing plate 3 and a waste paint tank 4, see figure 1 and figure 2 , the paint surface of the paint tank 1 is an inclined plane and is composed of a felt 2 and a felt press plate 3. The felt 2 is pressed by two felt press plates 3, and the two felt press plates 3 are all provided with U-shaped openings parallel to each other. To ensure the verticality of the wires, it is necessary to cut the felt 2 in the U-sh...

Problems solved by technology

Its disadvantage is that: in order to ensure the composition of three points and one line, there is still a margin at the bottom of the cut felt 2 and the felt press plate 3, so that the insulating varnish deposited at the bottom of the paint tank 1 cannot be fully utilized, resulting in a lot of waste of insulating varnish , which increases the cost of raw materials; and because the opening position of the felt 2 is not easy to determine, in the past, the cutting of the felt 2 was mostly performed with the experience of the operator, and it is easy to cause paint leakage due to the incision of the felt 2 not in place, which increases the cost of insulating paint. The waste also pollutes the environment; and the past paint pots do not have a constant temperature device, so the viscosity of the insulating varnish in the paint tank 1 is easily affected by the ambient temperature, which is not conducive to the stability of the quality of the enameled wire paint film; and the top of the paint tank 1 is open, so that the paint The insulating varnish in tank 1 is fully exposed to the air, which further reduces the insulation performance of the insulating varnish, and the insulating varnish easily absorbs water vapor in the air, thereby reducing the performance of the insulating varnish
