Painting technique for ballast

Abstract

The invention relates to a painting process used for a ballast. Firstly, the preprocessing of de-rusting and de-oiling is performed to the insulation and the rustprevention of a ballast workpiece; then the preprocessed work piece is directly hung on a painting automated production line; heating is performed to the workpiece through a heating device installed at the front part of an impregnating pond, so as to improve the temperature of the paint around the front end of the impregnating pond and to improve the penetrability of the paint to the workpiece when the work piece enters the impregnating pond, simultaneously a certain distance is arranged between the front end and the rear end of the impregnating pond to ensure the temperature of the paint adhered to the work piece to be reduced when the workpiece moves to the rear end of the impregnating pond, thereby increasing the adhesive force of the paint to the work piece and further reducing the discharged hazardous material during the painting process. At the moment, the workpiece is air-dried gradually and naturally after leaving the impregnating pond under the guiding of the pulling device of the production line, then enters the heating device to be heated and dried, and leaves the heating device, thereby finishing the primary painting. A plurality of spraying / impregnating can be performed to the workpiece on the production line.

Description

1. Technical field [0001] The invention relates to an insulation and anti-rust coating process applied to small electrical products, especially the improvement of the coating process of ballasts. 2. Background technology [0002] The so-called coating process refers to the spraying / dipping process. At present, the coating process applied to small electrical products, such as the spraying / dipping process for ballast insulation and anti-rust, still stays in the original manual operation stage, and the corresponding degree of mechanization and automation is relatively low. The process steps of anti-rust spraying / dipping paint are as follows: <1> pre-treat the ballast workpiece that needs to be insulated and anti-rust, that is, firstly carry out rust removal and oil removal; <2> carry out the first spraying / Immerse the paint to play the role of insulation. Manually hang the ballast workpiece on the painting rack of the traditional painting process, and then manuall...

AI Technical Summary

Problems solved by technology

[0003] For the existing ballast insulation and anti-rust spraying / dipping process, there are problems such as low degree of automation, high labor intensity, high production cost, low production efficiency, unguaranteed quality of coated products, and physical damage to operators. Disadvantages of greater harm and serious environmental pollution, providing a coating process applied to ballasts to obtain insulation, anti-rust spraying / impregnation, good quality, environmental protection and energy saving
