Spraying control method and device for wall 3D printer

Abstract

The invention discloses a spraying control method and device for a wall 3D printer. The spraying control method includes the following steps that the distance between a current spraying device and a target wall is obtained, and the distance between the spraying device and the target wall is controlled within the preset spraying distance range to complete the initialization process; a nozzle of thespraying device is controlled to move horizontally according to the preset speed, materials are sprayed in the process of horizontally moving, and the spraying thickness is checked in real time to becontrolled within the preset spraying thickness range; when the nozzle moves horizontally to the tail end and touches a side travel switch, thenozzle is controlled to stop moving horizontally and move vertically according to a nozzle vertically moving set value, the nozzle of the spraying device is continued to be controlled to move horizontally according to the preset speed, the materials are sprayed in the process of horizontally moving, and the spraying thickness is checked in real time to be controlled within the preset spraying thickness range, and the steps are carried out repeatedly until spraying work is completed. According to the spraying control method and device for the wall 3D printer, the materials can be accurately, uniformly, and quantificationally sprayed to the target wall.

Description

technical field [0001] The invention relates to the technical field of wall plastering, in particular to a spraying control method and device for a wall 3D printer. Background technique [0002] Nowadays, all kinds of wall plastering machines are widely used on construction sites to replace manual work. Wall plastering is a very important process in construction processing. This manual process occupies 10% of the total construction period. 30%~40%. However, this purely manual operation method has many unavoidable defects, which increases the labor intensity of workers, lengthens the construction period, increases construction costs, takes up more labor, and has a low degree of mechanization, making it difficult to control the construction quality. [0003] According to the construction industry standard, the thickness error of plastering the entire surface cannot exceed 3mm, but there are many problems with the plastering machines on the market, which cannot achieve the exp...

AI Technical Summary

Problems solved by technology

However, this purely manual operation method has many inevitable defects, which increases the labor intensity of workers, lengthens the construction period, increases construction costs, takes up more labor, and has a low degree of mechanization, making it difficult to control the construction quality.

[0003] According to the construction industry standard, the thickness error of plastering the entire surface cannot exceed 3mm, but there are many problems with the plastering machines on the market, and the expected effect cannot be achieved

Due to the inevitable mechanical vibration of the various parts of the entire plastering machine during the construction process, and the inability to accurately control the speed of the spraying material of the plastering machine, the material cannot be accurately, uniformly and quantitatively sprayed on the target wall.
