Automatic stain scraping and sweeping treatment device for indoor design

Abstract

The invention provides an automatic stain scraping and sweeping treatment device for indoor design. The automatic stain scraping and sweeping treatment device comprises a box body, wherein one side of the box body is open; a first rotating shaft is rotationally mounted in the lower part of the box body; a second rotating shaft is arranged above the first rotating shaft; a plurality of first chain wheels are fixedly mounted in the middle of the periphery of the first rotating shaft and the middle of the periphery of the second rotating shaft respectively; the first chain wheel on the lower side is in transmission connection with the corresponding first chain wheel on the upper side through a first chain; a plurality of crushing teeth are uniformly and fixedly mounted on the outer side of the first chain; and a coaxial first bevel gear is fixedly mounted at one end of the periphery of the first rotating shaft. The automatic stain scraping and sweeping treatment device is simple in structure and ingenious in conception; grinding tool bits are driven to rotate through the chain, and the grinding depths of the grinding tool bits which are distributed up and down are gradually increased from bottom to top, so that the grinding depths of the grinding tool bits are prevented from being too large; and meanwhile, the grinding tool bits can automatically reset after being separated from a wall every time, so that the situation that the uppermost grinding tool bit is excessively deeply fed to impact the wall surface too much to cause damage to the wall surface is avoided, and the service lives of the grinding tool bits are prolonged.

Description

technical field [0001] The invention belongs to the field of wall polishing devices, in particular to an automatic cleaning device for stains in interior design. Background technique [0002] When decorating a house, due to the many stains on the original wall skin, it is often necessary to clean up the original wall skin, or in order to eliminate some defects in the decoration process, it is necessary to clean up part of the wall surface, which is a very important and important part of wall decoration. For the process with a lot of tasks, it is usually time-consuming and labor-intensive to use a proprietary spatula to shovel, and the labor expenditure is large, or to use a grinding roller to polish the wall, but the grinding depth of the grinding roller is fixed. When deep grinding is required, the grinding roller The deeper the lower knife, the greater the damage to the wall, and at the same time affect the service life of the grinding roller cutter head, which cannot meet...

Problems solved by technology

[0002] When decorating a house, due to the many stains on the original wall skin, it is often necessary to clean up the original wall skin, or in order to eliminate some defects in the decoration process, it is necessary to clean up part of the wall surface, which is a very important and important part of wall surface decoration. For the process with a lot of tasks, usually use a proprietary spatula to remove it, which is time-consuming and labor-intensive, and the labor expenditure is large, or use a grinding roller to polish the wall, but the grinding depth of the grinding roller is fixed. When deep grinding is required, the grinding roller The deeper the knife, the greater the damage to the wall. At the same time, it affects the service life of the grinding roller head, which cannot meet the actual needs. Therefore, we have invented an automatic cleaning device for stains in interior design.
