Description

An automatic wall plastering machine

technical field

The invention relates to the field of construction machinery, in particular to an automatic wall plastering machine.

Background technique

Under the rapid development of society, the population grows rapidly, more and more people gather in cities, the urbanization is accelerated, our living and housing conditions are getting better and better, and at the same time, more housing is needed to meet people's living needs, so we The country's housing construction has been developing faster and faster. After the housing rough is completed, it is generally necessary to apply mortar to the wall, which is a heavy task. Now, manual painting is generally used, which faces the following problems:

1) The amount of painting works is large, requiring a lot of manpower and material resources, and there are certain deficiencies in the quality of painting;

2) The lower part of the wall can be directly painted by hand, but the higher part is not easy to be painted. It requires workers to build a shelf and paint on the shelf, which wastes too much manpower and the painting efficiency is also low;

3) Due to working at high places and working for a long time, there are certain hidden dangers for the personal safety of workers.

Based on the above reasons, some automatic wall plastering machines have appeared in the prior art to realize automatic wall plastering and improve the efficiency of wall plastering. However, it has certain defects. For example, it cannot be automatically loaded and needs to be manually loaded, and the labor intensity of workers is still very high. It is more difficult to load materials when the wall is wiped at a higher position. Manually measure the verticality of the wall wiper and the wall and position it, which results in inaccurate positioning and low smoothness of the wiped wall.

In foreign countries, mortar spraying is often used for wall painting, and the design and use of automatic wall cleaning machines are not common.

For example, Hasco Company in South Korea has developed and produced an electric high-pressure airless sprayer PRO-60N. This sprayer is composed of a main engine, a high-pressure pipe, a nozzle, etc. Wall spraying is not limited by location, but it also has shortcomings. Its spraying materials have certain requirements, only medium and high viscosity rubber, latex paint, etc. can be sprayed.

The originator of the wall decoration machine is actually Germany. In 1958, the Germans invented the first spraying machine. So far, many companies in Germany have been working on the research and development of automatic wall plastering equipment. The most representative of them is WAGNER. The most advanced product is the PC830 sprayer, which is an electric airless sprayer with lighter weight. The particles that can pass through can pass through 3mm at most, which has strong practicability and is mainly used for the application of adhesives on the exterior walls of houses.

In addition, the United States is the largest industrial power in the world. Its industrialization has promoted the rapid development of the construction industry, so its automatic wall plastering machine has also developed rapidly. For example, the sprayer GPX220 is a model of wall plastering equipment. Long life and other characteristics; wide range of applications, suitable for spraying of various materials.

To sum up, the development of foreign wall plastering machines started earlier and the technology is skilled, but they tend to be sprayed, and automatic wall plastering machines are less involved.
