Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building material grinding production, especially relate to a quantitative discharging device for building real stone paint powder grinding. BACKGROUND

[0002] The building real stone paint is a chemical mixture coating widely used in building outer wall decoration, which can firmly cover the object surface and has multiple functions such as protection, decoration and marking. The real stone paint is mainly mixed by natural color stone sand powder, synthetic resin, additives and other materials, and is processed by special process. The formed coating film has the characteristics of high molecular compound. In the production process of real stone paint, powder grinding is a crucial link. The fineness and uniformity of the powder directly affect the finished product quality and performance of the real stone paint. Therefore, an efficient and accurate grinding device is needed to ensure that the powder can reach the ideal fineness and uniformity during the grinding process, thereby improving the quality of the real stone paint.

[0003] At present, there are some devices for grinding building real stone paint powder on the market. For example, a building real stone paint powder grinding and screening device with the announcement number CN213669517U, which ensures the sufficient grinding of the powder through twice grinding. The device adopts advanced grinding technology and screening system, sends the powder into the grinding cavity, after the first grinding, the powder is sent into the second grinding area for further refinement, and finally the powder particles meeting the requirements are screened out through the screening assembly. This twice grinding design effectively improves the grinding efficiency and quality of the powder, and ensures the fineness and uniformity of the real stone paint powder.

[0004] However, there are still some problems in the discharging link. If the single discharging amount is too much, a large amount of powder is easy to accumulate between the grinding rollers, and even overflow from the edge of the grinding area, which will affect the grinding effect. If the staff needs to be responsible for uniform discharging all the time in order to ensure the grinding effect, it will increase the work difficulty and intensity of the staff. Long-time discharging operation in one state not only easily leads to the fatigue of the staff, but also may affect the grinding effect due to improper operation. UTILITY MODEL CONTENTS
