Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, specifically to a powder material metering and control device. Background Technology

[0002] Powders are aggregates composed of numerous small particles. Their common characteristics are: they have many discontinuous surfaces, a large specific surface area, and are composed of many small particles.

[0003] For example, utility model patent CN213111638U discloses a metering device for powder conveying, relating to the field of powder conveying technology. To address the problem that existing methods generally require metering of powder before conveying, and that the metering accuracy is easily reduced due to powder sticking together during the metering process, a heating layer is provided at the lower end of the powder hopper, and the heating layer is fixedly connected to the powder hopper. A motor housing is provided on the outer wall of one side of the heating layer, and the motor housing is fixedly connected to the heating layer. A first drive motor is fixedly installed inside the motor housing, and a first coupling is provided at the output end of the first drive motor. An electric heating roller is provided at one end of the first coupling, and the output end of the first drive motor is connected to the electric heating roller through the first coupling. However, there is a problem that while the electric heating roller disperses powder clumps within the heating layer, it cannot disperse powder clumps in the lower layer of the heating layer, resulting in incomplete dispersion of powder clumps and ultimately reduced dispersion efficiency. Therefore, we propose a powder material metering and control device. Utility Model Content

The side gear 410 drives the gear ring 412 to rotate, which in turn drives the rotating ring 413 to rotate. The powder clumps within the rotating ring 413 are driven to rotate, and at this time, the powder clumps are in contact with the heating roller 415 and then with the dispersing strip 416. Simultaneously, the first rotating shaft 43 rotates, which in turn drives the first pulley 44 to rotate. The first pulley 44 drives the second pulley 46 to rotate via the belt 45, which in turn drives the second rotating shaft 47 to rotate. The second rotating shaft 47 drives the feeding screw roller 48 to rotate. The feeding screw roller 48 performs a screw feeding action on the powder entering the discharge pipe 3, improving the synchronization of feeding.
