Description

Technical Field

[0001] The utility model relates to a dry powder pressing and molding technology, in particular to a full-automatic feeding device for hard powder. Background Art

[0002] Traditional feeding devices cannot meet the fluidity of hard powders, especially since powders are difficult to pass through long and thin feeding pipes, which can easily cause agglomeration and blockage. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a fully automatic feeding device for hard powder, which can realize automatic feeding of hard powder.

[0004] The technical solution of this utility model:

[0005] A fully automatic feeding device for hard powder, the feeding device comprising a silo, a feeding box, and a feeding pipe, the silo and the feeding box are both mounted on the main body of a dry powder hydraulic press, the silo is located at the top and has an opening at the bottom, the feeding box is located at the bottom and has an opening at the top, and the feeding pipe connects the bottom opening of the silo and the top opening of the feeding box; the feeding device also comprises a stirring spring, the stirring spring is mounted in the silo, the lower end of the stirring spring extends through the bottom opening of the silo and extends into a section of the feeding pipe;

[0006] The stirring spring rotates to stir the powder in the silo and the feed pipe, breaking up the powder in the silo and the feed pipe, effectively preventing the powder from agglomerating and clogging. At the same time, when the stirring spring rotates, the stirring spring will vibrate elastically under the action of external force, thereby further improving its stirring effect.

[0007] The feeding device also includes a stirrer, which is composed of a stirring motor, a stirring shaft, and a stirring blade. The stirring motor is installed on the silo, and the stirring shaft is arranged in the silo. The upper end of the stirring shaft extends through the upper cover of the silo and is connected to the stirring motor. The lower end of the stirring shaft is installed with an elbow joint and is connected to the upper end of the stirring spring through the elbow joint. The stirring blade is installed on the stirring shaft, and the stirring blade is located in the silo.

[0008] The stirring motor drives the stirring shaft to rotate, and the stirring blade rotates with the stirring shaft to stir the powder in the silo to break up the powder in the silo to prevent agglomeration and blockage. The stirring spring also rotates with the stirring shaft. The stirring motor is used as a power source to drive the stirring spring to rotate. There is no need to set up an additional power source to drive the stirring spring to rotate, and the overall layout is more reasonable and compact.

[0009] There are two groups of stirring blades, one above and one below, so the stirring effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The stirring spring 1-4 rotates to stir the powder in the silo 1-1 and the feeding pipe 1-3;

[0015] The feeding device 1 also includes a stirrer, which is composed of a stirring motor 1-5, a stirring shaft 1-6, and a stirring blade 1-7. The stirring motor 1-5 is installed on the silo 1-1, and the stirring shaft 1-6 is arranged in the silo 1-1. The upper end of the stirring shaft 1-6 extends through the upper cover of the silo 1-1 and is connected to the stirring motor 1-5. The lower end of the stirring shaft 1-6 is installed with an elbow joint 1-8, and is connected to the upper end of the stirring spring 1-4 through the elbow joint 1-8. The stirring blade 1-7 is installed on the stirring shaft 1-6, and the stirring blade 1-7 is located in the silo 1-1;

[0016] The stirring motor 1-5 drives the stirring shaft 1-6 to rotate, and the stirring blade 1-7 rotates together with the stirring shaft 1-6 to stir the powder in the silo 1-1, and the stirring spring 1-4 also rotates together with the stirring shaft 1-6;
