Description

A powder press feeding device Technical Field

[0001] This utility model relates to the technical field of press feeding devices, specifically a powder press feeding device. Background Technology

[0002] By using the stirring blades, the feeding device can break up the powder aggregated near the discharge port under the drive of the drive component, preventing powder agglomeration from causing uneven discharge and thus ensuring normal powder supply. The powder forming press can achieve high-precision forming and is suitable for the production of parts that require strict dimensional control. Due to the precision of its forming mold and the uniformity of the powder material, the powder forming press can ensure the repeatability and consistency of the product.

[0003] For example, the powder press feeding device disclosed in the authorization announcement number CN211135521U includes a pressing force measuring sensor. Two supporting base plates are arranged above the pressing force measuring sensor. A fixing block is fixedly connected to one side of each of the two supporting base plates. A material cavity is formed on one side of the two fixing blocks. A feeding scraper shoe is slidably connected to the top of the fixing block. A gravity feeding pipe is arranged above the feeding scraper shoe.

[0004] Although it achieves the advantages of fully automatic and accurate feeding, adjusting feeding error based on the previous feeding result, eliminating spillage and waste, and high feeding efficiency by using the principle of servo drive to automatically adjust the feeding depth through the set controller, material chamber, servo drive unit, feeding scraper shoe, gravity feeding pipe, and pressing force measuring sensor, it can transmit the received signals to the controller in a timely manner. When the controller generates an instruction, it quickly transmits it to the servo drive unit, resulting in accurate and fast feeding with high efficiency and certain practicality.

[0005] However, this does not solve the problem that existing feeding devices for such presses are generally not conducive to the convenient sequential rotation and quantitative conveying of different types of powders during use. This affects the convenience of the powder press feeding device in conveying different types of powders in a sequential rotation and quantitative conveying, and it is not conducive to the convenient movement of powder to a designated area for conveying and discharging. This also affects the flexibility of the powder press feeding device in moving powder to a designated area for conveying and discharging. Summary of the Invention
