Description

Technical Field

[0001] The utility model relates to the technical field of plaster machines, in particular to an automatic plaster machine. Background Art

[0002] Plaster machine is a general term for a series of machines for making and processing plasters, and generally refers to machines and equipment related to plaster making. The previous manual plaster spreading has gradually developed into fully automatic operation, which has also led to an increasing number of plaster machines. The development of plaster machines has evolved from manual plaster making to semi-automatic plaster making, and then to fully automatic operation. The production line is composed of many different machine models. The first process of plaster processing is stirring, which requires a plaster mixer, which is a primary plaster machine. The plaster raw materials are stirred and mixed to form a plaster. In the prior art, when the plaster mixer is used, in order to reduce the participation of staff, the plaster is often stirred by an electric machine. The stirring rod is driven by a motor to rotate, so that the stirring rod drives the plaster to move in the plaster tube to achieve the stirring of the plaster. After the stirring is completed, the discharge port of the plaster mixer needs to be opened to discharge the plaster. However, many plasters after stirring have a high viscosity. When discharging, the plaster is easy to adhere to the inner wall of the discharge space of the plaster mixer, resulting in a slow discharge speed of the plaster mixer, which affects the working efficiency of the plaster mixer.
