[0002] Plaster anti-cracking and waterproof mortar is a special mortar widely used in construction and decoration projects. It has the characteristics of crack resistance, waterproofness, bonding strength, construction performance, shrinkage and environmental protection.

[0003] For example, the announcement number CN 216658465 U discloses a preparation device for polymer cement waterproof mortar, including a processing box, a driving motor and a solenoid valve. Feed pipes are provided on the tops of the left and right ends of the processing box, a connecting shaft is installed at the output end of the driving motor, and limit blocks are provided on the upper and lower ends of the fixed pipe. The outer side of the positioning rod is connected to a bulk material tray, and a positioning ring is installed on the outer side of the middle part of the connecting shaft. The preparation device for polymer cement waterproof mortar can drive the bulk material tray to rotate while controlling the connecting shaft to drive the stirring rod provided on the outer side of the end thereof to rotate to stir the raw materials for production, and can break up the raw materials put into the device to avoid the accumulation of raw materials. During the rotation of the bulk material tray, under the extrusion of the fixed block with a triangular structure in the longitudinal section, the anti-wear block and the mounting frame can drive the bulk material tray to rise and fall reciprocally, so that the bulk material tray vibrates to avoid the raw materials from adhering to the bulk material tray.
