Description

Technical Field

[0001] The utility model relates to the technical field of coating powder grinding, and more specifically, to a superfine powder coating powder grinding device. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Powder coating is completely different from general coatings. It exists in the form of fine powder. Since it does not use solvents, it is called powder coating. Powder coating is mainly divided into two categories, thermosetting powder coating and thermosetting powder coating. Powder coating needs to be ground into powder using a fine powder coating grinding device during production;

[0003] Existing crushing equipment often needs multiple grindings to meet production needs, but multiple grindings seriously affect the processing efficiency, and it is very easy to get blocked during the grinding process, which requires a lot of time for maintenance, thus greatly delaying the processing progress.

[0004] The utility model of Chinese patent application number CN202220709165.6 discloses a multi-stage grinding ultrafine powder production equipment, including a grinding box, one side of the grinding box is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating shaft, the other end of the rotating shaft extends to the inside of the grinding box and is fixedly connected to a grinding disc, the inside of the grinding box is located below the grinding disc and is fixedly connected to a grinding plate, the middle of the grinding plate is provided with a feeding port, the outer surface of the rotating shaft is fixedly connected to a synchronous wheel, the synchronous wheel is connected to a rolling and crushing mechanism and a top pressure component through a belt drive, and an anti-blocking mechanism is provided at the bottom of the grinding box, so that the device can drive the rolling and crushing roller to perform primary crushing and rolling on the raw material through the motor, and then use the grinding disc and the grinding plate to perform secondary grinding on the processed ground powder, so that the device can quickly perform multi-stage grinding on the raw material, thereby greatly accelerating the processing efficiency of ultrafine powder;

[0005] Then, combined with the drawings in the specification, it can be seen that while the raw materials are primarily crushed and rolled by the crushing roller, the processed ground powder is then subjected to secondary grinding by the grinding disc and grinding plate. After grinding, it is inevitable that some powder particles will be larger, resulting in failure to meet the requirements. The inclusion in the finished product will affect the quality of the finished product, and it is inconvenient to perform vibration screening when unloading, which affects the quality of the finished product.
