Description

TECHNICAL FIELD

[0002] In the production and research and development process of wet pressing of complex shape cement products, raw material fluidity experiments are of great necessity. Complex shape cement products, such as those containing thin walls, deep cavities and multiple corners, have very high requirements for the fluidity of raw materials. Insufficient fluidity of raw materials can result in incomplete filling of the mold cavity, and excessive fluidity can cause leakage from the mold plate gap during pressing. Through experiments, the optimal fluidity parameters of raw materials can be accurately determined to ensure that they can adapt to complex mold cavity structures and ensure the integrity of product molding.

[0003] A cement testing device with the publication number CN103063546A, specifically a cement fluidity rapid testing plate for quickly testing cement fluidity, includes a square transparent glass plate. At least four symmetrically diverging radial scale lines are engraved on the back of the glass plate test surface from the center point of the glass outward. Only the square transparent glass plate and the scale lines are used to realize basic fluidity testing, which cannot simulate the sealing environment and pressing conditions of complex shape mold cavities, and has poor adaptability.

[0004] A cement mortar fluidity tester with the publication number CN110108596B includes a jumping table and a cleaning device. The jumping table includes a rack base, a cam, a first motor, a sleeve, a push rod, a fixed table top and a jumping table top. The rack base is formed by three steel vertical rib plates fixed at an angle of 120 degrees on the sleeve. The push rod is a cylindrical rod in the sleeve. The device mainly tests the flow performance of mortar on the jumping table, lacks structure adaptation, automatic sealing control and mold plate cleaning functions for complex mold cavities, and cannot meet the precise testing requirements of the fluidity of complex shape cement products.

[0005] There is an urgent need for an experimental device that can realize automatic regulation and control and multifunctional assistance to fill the gap in the prior art. SUMMARY
