Coating machine with defoaming device

Abstract

The invention discloses a coating machine with a defoaming device. The coating machine comprises a machine base, and a coating machine back roller, a coating roller, a material taking roller and a metering roller which are sequentially arranged on the machine base, wherein a material storage disc is arranged below the coating roller, the material taking roller and the metering roller; the defoaming device is arranged at the side, close to the coating roller, in the material storage disc; a controller is further arranged on the machine base; the defoaming device is arranged at the side, close to the coating roller, in the material storage disc; a partition plate is fixed to the side, close to the metering roller, in the material storage disc; bubbles floating on the surface of a coating are eliminated through the defoaming device; and the bubbles and floating objects floating on the surface of the coating are isolated through the partition plate. According to the coating machine with the defoaming device, the surface of a product is free of water ripples and short line marks, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a coating machine with a defoaming device. Background technique [0002] Coating is a material that can be coated on the surface of an object by different construction techniques to form a solid film with strong adhesion, certain strength and continuity. The film formed in this way is commonly called a coating film, also known as a paint film or a coating. [0003] At present, paint construction needs to be evenly stirred, and then the paint is pumped into the construction tray through a diaphragm pump. There are two shortcomings in this method. One is that there will be some air bubbles after stirring, and the other is that when the material is pumped, the paint will be extruded through the filter to produce air bubbles, resulting in bubble marks and color difference on the surface of the product. [0004] Improvements such as figure 1 As shown, the coating machine back roll...

AI Technical Summary

Problems solved by technology

There are two shortcomings in this method. One is that there will be some air bubbles after stirring, and the other is that when the material is pumped, the paint will be extruded through the filter to produce air bubbles, resulting in bubble marks and color difference on the surface of the product.

[0004] Improvements such as figure 1 As shown, the coating machine back roller 11, coating roller 12, take-up roller 13, and metering roller 14 that are arranged in sequence are fixed with a partition 8 near the side of the coating roller in the storage tray 20, through which the partition 8 By isolating some air bubbles floating on the surface of the paint, the problems of water ripples and short line marks on the surface of the product can be alleviated to a certain extent, but the bubble marks on the product will still exist, which will also make the fluidity of the paint in the storage tray worse. The paint needs to be stirred manually, but the strength and speed of manual stirring cannot be guaranteed, resulting in color difference on the surface of the product, and there will also be bubble marks that affect the appearance of the product and affect the quality of the product
