Steel plate surface painting unit with magnetic stirring bar

Abstract

The invention relates to a steel plate surface painting device with a magnetic stirring rod. The steel plate surface painting device comprises a paint slot (1), wherein a paint liquid is arranged in the paint slot (1); and a steel roller (2), a rubber roller (3) and a back-to-back roller (4), which are longitudinally arranged, are erected on the paint slot (1) from left to right. The steel plate surface painting device is characterized in that the magnetic stirring rod (13) is arranged in the part, at the left side of the steel roller (2), of the paint slot (1), wherein the surface of the magnetic stirring rod (13) is provided with inclined threads which extend from the middle part to front and rear ends; the magnetic stirring rod (13) have magnetism, so that the magnetic stirring rod (13) can cling to the left side surface of the steel roller (2), and can rotate along with the rotation of the steel roller (2), and therefore, the paint liquid near the magnetic stirring rod (13) is dispersed for being conveyed from the middle part to the front and rear ends by virtue of the magnetic stirring rod (13). The steel plate surface painting device with the magnetic stirring rod has the advantages that a steel plate surface coating is uniform, and the product quality is good.

Description

technical field [0001] The invention relates to a steel plate surface painting device with a magnetic stirring bar. Background technique [0002] The color-coated steel plate is made of cold-rolled steel strip and galvanized steel strip (electro-galvanized and hot-dip galvanized) as the substrate on the continuous unit, and after surface pretreatment (degreasing and chemical treatment), it is coated with a layer of or multi-layer liquid paint, and the plate obtained after baking and cooling is the coated steel plate. Because the coating can have various colors, it is customary to call the coated steel plate as color coated steel plate. And because the coating is carried out before the steel plate is formed, it is called pre-coated steel plate abroad. [0003] The painting device on the traditional color-coated steel production line is to put the paint liquid to be coated in the paint tank, and transfer a layer of paint film to the rubber roller through the steel roller rot...

AI Technical Summary

Problems solved by technology

However, in the traditional steel plate surface painting device, the paint liquid is prone to precipitation in the paint tank, resulting in uneven paint liquid, or the mixture of various paint liquids is prone to produce floating colors, resulting in discoloration of the paint liquid coating on the final steel plate surface. spot, product quality is not up to standard and other defects
