Description

Technical Field

[0002] Cement-based and gypsum-based plastering are widely used in the building materials industry. When manufacturers develop admixtures for plastering, they need to apply the mixed plastering mortar to evaluate its workability.

[0003] However, the current methods for judging plastering construction still have the following shortcomings:

[0004] 1. Currently, plastering is generally done by hand, and the performance of the work is judged by the plasterer's touch. However, the plastering thickness is uneven, and it is impossible to accurately control the size and thickness of the plaster blocks, resulting in inaccurate test data.

[0005] 2. When using existing coating tools for plastering, since the platform is a flat plate, different thicknesses and sizes of plaster can only be achieved by adjusting the height and stroke of the scraper. The performance of the plaster can only be judged by visual inspection, which cannot quantify the performance and results in poor accuracy. Utility Model Content

[0042] The lifting drive device lowers the lifting plastering platform to form a 30cm*30cm*2cm concave groove, which is then filled with the mortar to be evaluated. After filling, the lifting drive device raises the plastering platform to be level with the work platform, creating a 30cm*30cm*2cm plastering mortar block on the work platform. Then, the translation drive device moves the scraper forward at a constant speed through the moving frame, scraping from one side of the plastering mortar block to the other for plastering evaluation. During this process, force and displacement sensors detect and acquire changes in the force and displacement of the scraper in real time, displaying a force-displacement curve on the screen. After plastering is completed, the controller can calculate the torque based on the acquired force and displacement (lever arm) parameters, allowing the user to judge the quality of the mortar's workability based on the torque magnitude.
