[0038] Working principle: The fixed plate 11 is installed with an electric push rod 12, the telescopic end of the electric push rod 12 is connected with a sliding block 13, a square sliding block 14 cooperates with the sliding block 13 and can slide on a fixed column 15, a threaded column 16 is connected with the square sliding block 14 and contacts with a blanking valve 17, the electric push rod 12 drives the sliding block 13 to move by accurately controlling its telescopic stroke, and then drives the square sliding block 14 to move up and down along the fixed column 15, so as to adjust the extrusion degree of the threaded column 16 to the blanking valve 17, when the blanking valve 17 is extruded more, the opening becomes smaller, and the powder feeding amount decreases, when the blanking valve 17 is extruded less, the opening becomes larger, and the powder feeding amount increases. In this way, automatic quantitative feeding of the powder is realized to meet the accurate requirements of different production processes or use scenarios for the powder feeding amount, the quantitative feeding device can strictly control the feeding amount of each raw material, ensure that the component ratio is accurate and correct, and thus ensure that the quality and performance of the product are stable, and accurate quantitative feeding can ensure that the amount of powder used each time is just right, avoiding waste of raw materials due to excessive feeding.

[0039] The container 1 serves as a container for storing powder, and a support frame 2 and a support plate 3 provide a stable support structure, a motor 4 is installed at a suitable position and connected with an oval plate 6 through a connecting column 5, when the motor 4 is started, the oval plate 6 is driven to do circular motion, the oval plate 6 contacts with a disc 7, due to the shape characteristics of the oval plate 6, the disc 7 is periodically pushed up and down during the rotation of the oval plate 6, the disc 7 is connected with a sliding rod 8, the sliding rod 8 is sleeved with a spring 9, one end of the spring 9 contacts with the disc 7, and the other end is connected with a baffle 10. When the disc 7 moves upward, the spring 9 is compressed, when the oval plate 6 rotates to a specific position, the pushing force on the disc 7 decreases, the spring 9 releases the elastic potential energy and pushes the disc 7 to move downward quickly, so that the components connected with the disc 7 vibrate. This vibration is transmitted to the powder barrel 18 and the blanking valve 17 through the related connection structure, preventing the powder from accumulating in these parts, ensuring that the powder can be smoothly fed, many powders have certain viscosity or are easy to be adsorbed and aggregated between particles, during the feeding process, these powders will accumulate in the hopper, pipeline 19 and other parts, block the channel, by vibrating the feeding device, the adsorption force and aggregation structure between the powders can be destroyed, which helps the powder to be more uniformly and quickly fed, especially suitable for precise feeding.
