technical field

The invention relates to the field of automation equipment, in particular to equipment for producing solid water-based rock slices, in particular to a high-efficiency, energy-saving and environment-friendly scraping machine.

Background technique

Rock flake paint, also known as imitation granite paint and granite rock paint, is a new type of pure water-based sand wall-shaped architectural paint that does not contain any solvent-based substances. The solid water-based rock flakes produced through the production of rock flake paint are rich in the style of granite, the connotation of granite, the nobility of granite, and the grade of granite. It is an upgraded variety of traditional natural real stone paint. After spraying and decoration, the large patterns, big ideas, good-looking and firm, cool like the rich texture of stone, giving people a solemn, rough and atmospheric visual enjoyment like natural granite. A single boring sand wall-like real stone paint or other architectural coatings lack the artistic style of granite texture, and cannot match the effect of granite paint.

In the current existing technology for making solid water-based rock slices, it needs to be completed through multiple independent and separate process steps, including spraying, heating and drying, natural cooling and finished product retrieving. Among them, the production principle of spraying is to use manual brushing on plastic plates (such as PVC boards). Using manual brushing will waste a lot of labor, and there are certain technical requirements for labor, and the efficiency of manual production is low. The thickness of the product produced by the brushing method is uneven, and there will be color difference, and the production quality of the product is low. Or carry out spraying on plastic film with the mode of mechanical spraying, and the material of mechanical spraying is many, and waste is big, and environmental pollution is serious, also can easily cause mutual pollution when multi-color registering spraying. The heating and drying process is completed by outdoor drying or heating and drying. The production process is relatively primitive, and drying takes up a lot of outdoor space, and production is affected by factors such as weather. In addition, the traditional spraying process will cause the discharge of waste paint, causing serious environmental pollution, resulting in great waste.
