[0072] The feeding rack 210 is installed obliquely on the top of the powder box body 100, and a material guiding space 211 is provided in the feeding rack 210;

[0073] The feed pipe 220 is threadedly connected to a side of the feed frame 210 away from the powder box body 100 , and the feed pipe 220 is communicated with the material guiding space 211 .

[0074] In this embodiment, the feeding rack 210 is installed on the powder box body 100 at an angle because it is convenient to pour powder when it is tilted. The feeding tube 220 is detachable to facilitate subsequent replacement and cleaning of the feeding tube 220.

[0075] In one embodiment, the stirring member a 300 includes a rotating rod 310, a stirring blade 320 and a stirring tooth set 330;

[0076] The rotating rod 310 is rotatably mounted in the powder box body 100. A stirring chamber 110 is provided in the powder box body 100. The rotating rod 310 is located in the stirring chamber 110. The vibration motor 600 is mounted in the rotating rod 310.

[0077] The stirring blade 320 is symmetrically mounted on the rotating rod 310;

[0078] The stirring tooth set 330 is symmetrically mounted on the rotating rod 310, and the cross section formed by the two stirring tooth sets 330 and the cross section formed by the two stirring blades 320 are perpendicular to each other;

[0079] The linkage assembly 400 includes a housing 410 , a first pulley 420 , a second pulley 430 , and a belt 440 ;

[0080] One end edge of the shell 410 is installed on one side of the powder box body 100, and the other end edge of the shell 410 is installed on one side of the driving device 500;

[0081] One end of the rotating rod 310 passes through the powder box body 100 and extends out of the powder box body 100, and the rotating rod 310 extending out of the powder box body 100 is fixedly connected to the first pulley 420;

[0082] The second pulley 430 is fixedly mounted on the driving shaft of the driving device 500;

[0083] The belt 440 is sleeved on the first pulley 420 and the second pulley 430;

[0084] The first pulley 420 , the second pulley 430 , and the belt 440 are all located in the housing 410 .

[0085] In this embodiment, by starting the driving device 500, the driving device 500 drives the second pulley 430 to rotate, and the second driving rotation drives the belt 440 to rotate, and the rotation of the belt 440 drives the first pulley 420 and the rotating rod 310 to rotate. After the rotating rod 310 rotates, it drives the stirring blade 320 and the stirring tooth group 330 to rotate. The powder is fully mixed by the rotation of the stirring blade 320 and the stirring tooth group 330. The stirring blade 320 is used to scrape off the powder attached to the inner wall of the powder box body 100, so as to prevent excessive adhesion of powder to the inner wall. The stirring tooth group 330 is used to fully stir the mixed powder. During the stirring process, the vibration motor 600 is started at the same time to prevent excessive adhesion of powder to the rotating rod 310, the stirring blade 320 and the stirring tooth group 330.

[0086] It should be noted that the housing 410 is used to prevent the overflowed powder or external dust from excessively adhering to the first pulley 420 and the second pulley 430 , thereby affecting the rotation of the first pulley 420 and the second pulley 430 .

[0087] Furthermore, there is a distance between each two stirring teeth of the stirring tooth group 330, and the distance between them is 2-5 cm. If the distance is too small, some powder will not be discharged from the gap between the two stirring teeth, which will affect the powder mixing effect. When the distance is 2-5 cm, the stirring and mixing effect is better, which is explained here.

[0088] In one embodiment, the stirring member b 700 includes a servo motor 710 and a rolling gear 720;

[0089] The servo motor 710 is symmetrically mounted on the feeding structure 200;

[0091] The rolling gear 720 is fixedly connected to the output shaft of the servo motor 710 that passes through the feeding structure 200;

[0092] The two servo motors 710 rotate in opposite directions.

[0093] In this embodiment, by starting two servo motors 710, the two servo motors 710 respectively drive the grinding gears 720 to rotate. The two grinding gears 720 are not meshed with each other. The two grinding gears 720 are separated by a distance of 0.8-1.2 cm. The two grinding gears 720 crush the larger lumps of powder, and then stir them through the stirring element a 300 after crushing, so that the powder can be mixed more fully.

[0094] In one embodiment, the powder box body 100 is symmetrically provided with mounting members 800 , and one of the mounting members 800 passes through the shell 410 and extends outside the shell 410 .

[0095] In this embodiment, the mounting member 800 is used to facilitate the installation of the powder box device on the powder forming equipment.

[0096] In one embodiment, a discharge port 900 is formed at the bottom of the powder box body 100 .

[0097] In this embodiment, the discharge port 900 discharges the stirred powder.

[0098] It should be noted that the stirring tooth group 330 is composed of multiple stirring tooth groups 330. Multiple stirring teeth can reduce energy loss and improve the working efficiency of the stirring and driving motors. After the powder is fully stirred, the powder goes out from the discharge port 900 and falls into the material hole that is in sliding contact with the powder box.

[0099] Furthermore, the driving device 500 may be a rotating motor or other components that drive the second pulley 430 to rotate, which is not limited here.

[0100] The working principle of this utility model:

[0101] By starting the driving device 500, the driving device 500 drives the second pulley 430 to rotate, and the second driving rotation drives the belt 440 to rotate, and the rotation of the belt 440 drives the first pulley 420 and the rotating rod 310 to rotate, and the rotating rod 310 rotates and drives the stirring blade 320 and the stirring tooth group 330 to rotate. The powder is fully mixed by the rotation of the stirring blade 320 and the stirring tooth group 330. The stirring blade 320 is used to scrape off the powder attached to the inner wall of the powder box body 100, so as to prevent excessive adhesion of powder to the inner wall. The stirring tooth group 330 is used to fully stir the mixed powder. During the stirring process, the vibration motor 600 is started at the same time to prevent excessive adhesion of powder to the rotating rod 310, the stirring blade 320 and the stirring tooth group 330.
