Problems solved by technology

[0007] However, there are many manufacturing devices in this method, and the manufacturing process is complicated.
The cost of conductive film, primer, powder coating, etc. is high, and of course the cost of coating glass containers is also high
In addition, due to the great differences in the composition materials, size and shape of glass containers, even with this method, it is difficult to form a uniform thickness of coating film on the surface of glass containers

[0035] The first embodiment refers to figure 1 As shown, the conductive treatment device 10 and the electrostatic coating device 100 are arranged in sequence to form a glass container coating production device 30 .

[0036] Using the glass container coating production device 30, the flow chart of coating production is as follows figure 2 shown. Among them, STEP2 represents the conductive treatment process, and STEP4 represents the electrostatic coating process. figure 2 Among them, there is a STEP3 between STEP2 and STEP4, that is, the drying process of the conductive layer. But in actual production, the conductive layer dries naturally quickly, so STEP3 can also be omitted, and STEP2 enters STEP4 directly.

Abstract

The invention relates to a coating preparation device for a glass container with high production efficiency, strong binding power, and uniform static coating layer on the surface of the glass container. The device comprises an electric-conducting treatment device and a static coating device, wherein the electric-conducting treatment device coats the conducting liquid with interfacial active agent on the glass container surface to form a conducting layer, and the static coating device coats the liquid paint on the conducting layer to form a uniform static coating layer.

Description

technical field [0001] The invention relates to a coating production device for a glass container and a coating production device with uniform coating film and high coating production efficiency. Background technique [0002] Generally, the coating method of glass containers mainly adopts the spraying method, that is, the liquid paint is sprayed on the surface of the glass container, and in order to improve the decoration, deep processing such as printing and bronzing is carried out on the coating surface. [0003] However, when spraying is used for painting, it is inevitable that the paint will be sprayed to places other than the surface of the glass container. In other words, most of the paint is not sprayed on to form a film on the surface of the glass container, but is wasted. From the perspective of saving resources and protecting the environment, it is necessary to effectively recycle these wasted paints. [0004] For this problem, there is a plan to use the electros...
