[0002] A powder forming machine is a device that processes loose powder into a certain size, shape, density and strength. The main implementation method of powder forming is to feed a certain amount of powder into a mold on the powder forming machine, and then use the mold to press the powder and then separate it into a mold.

[0003] Powders usually need to be screened before pressing and molding, but traditional powder molding machines do not have screening functions. The screening process is usually performed manually, with low screening efficiency and inconvenient multi-stage screening.

[0004] For example, a powder forming machine with a multi-stage screening function disclosed in Chinese patent CN216297079U can make the first sliding plate and the second sliding plate reciprocate, so that the first filter screen and the second filter screen can automatically screen the powder, saving manpower and having high screening efficiency. During the reciprocating motion of the first sliding plate and the second sliding plate, the setting of the vibration device can make the first sliding plate and the second sliding plate vibrate laterally during the motion, thereby accelerating the screening of the powder.

[0005] However, the powder added to the device during the powder screening process may have agglomerated parts, and the agglomerated powder may accumulate on the filter surface, thereby affecting the powder screening efficiency.

[0006] For this reason, we urgently need to provide a powder forming machine with a multi-stage screening function. Utility Model Content

By setting two pulling units, the powder is screened in multiple stages, and the two vibration units are used to collide with the two screen frames 602 to make the two screen frames 602 vibrate, thereby improving the powder screening efficiency of the screen frames 602.

[0029] The breaking up unit includes a feed port 401, a motor 402, a connecting rod 403, a bearing 404, a mounting plate 405 and a clapper 406. The feed port 401 is fixedly installed on the top of the screening box 2, the motor 402 is fixedly installed in the middle of the right side of the feed port 401, one end of the connecting rod 403 is fixedly installed on the output end of the motor 402 and is located inside the feed port 401, and the end of the connecting rod 403 away from the motor 402 is fixedly installed on the inner ring of the bearing 404. The connecting rod 403 is supported by the bearing 404, so that the connecting rod 403 rotates more smoothly. The bearing 404 is fixedly installed on the left side inside the feed port 401, the mounting plate 405 is fixedly installed on the outside of the connecting rod 403, and the clapper 406 is fixedly installed on the outer surface of the mounting plate 405.

Embodiment 2:

[0031] On the basis of Example 1: the vibration unit includes motor 2 501, rotating shaft 502, disc 503, outer rod 504, spring 505 and push rod 506, motor 2 501 is fixedly installed on the right side of screening box 2, rotating shaft 502 is fixedly installed on the output end of motor 2 501 is located inside screening box 2, disc 503 is fixedly installed on the outside of rotating shaft 502, outer rod 504 is fixedly installed on the outside of disc 503, one end of spring 505 is fixedly installed inside outer rod 504, push rod 506 is fixedly installed on the other end of spring 505, and the screen frame 602 is collided with by push rod 506, so that the screen frame 602 vibrates, thereby improving the powder screening efficiency.

[0033] When in use, the powder to be screened is added into the screening box 2 through the feed port 401, and the motor 1 402 is started at the same time to drive the connecting rod 403 to rotate. When the connecting rod 403 rotates, the clapper 406 is driven to rotate to beat the added powder to break up the agglomerated powder. The beaten powder is screened through the two screen frames 602 respectively. During the screening process, the motor 2 501 is started to drive the rotating shaft 502 to rotate. When the rotating shaft 502 rotates, the disc 503 is driven to rotate, so that the top rod 506 collides with the bottom of the screen frame 602, causing the screen frame 602 to vibrate, thereby improving the powder screening efficiency. The screened powder is transported to the powder molding machine body 1 by the feeding hose 3 for pressing and molding. When the screen frame 602 needs to be cleaned, the handle 603 is pulled to make the screen frame 602 slide outward along the slide rail 601, so that the screen frame 602 is taken out from the inside of the screening box 2, and the impurities on the surface of the screen frame 602 are cleaned.
