The invention provides a blanking device used in metal powder processing. It has the following beneficial effects:

1. The present invention sets up a unloading mechanism so that when the metal powder falls through the inner wall of the bearing, it will quickly rotate through the inner wall of the unloading tube. When the unloaded metal powder is scattered on the inner wall of the unloading tube, it will contact the scraper. And scrape it off quickly, fully cleaning the inner wall of the unloading tube, and ensuring that the metal powder will fully fall, and there will be no problem of dust accumulation blocking the unloading tube due to residue.

2. By setting up the unloading mechanism, the dust on the inner wall of the unloading tube is cleaned by scraping the scraper and the unloading tube to make it fall faster, and at the same time, the dust falling from the top is fully removed through the fixed rod. The dust is dispersed to ensure that the dust can fall evenly in the channel of the unloading pipe, reducing the problem of large amounts of slipping and adhering to the inner wall of the unloading pipe, and further dispersing the dust so that it can be unloaded and collected more evenly, and at the same time The outer wall of the scraper is fully wiped and cleaned by the sliding movement of the scraper, which avoids fully scraping off the residue adhered to the outer wall of the scraper while the discharge pipe is rotating for a long time, and comprehensively improves the cleaning effect of the discharge pipe and the outer wall of the scraper. , and ensure that the falling efficiency of dust is not affected.

3. By setting up a cleaning mechanism, as the connection cover rises, the threaded rod is cleaned through the bristles on the inner wall of the connection cover. At the same time, a large amount of dust swept away by the threaded rod is shaken off by lowering the lifting ring B, and then the bristles are connected to each other. While the threaded rod is cleaning, as the fan blade rotates, the lifting ring A and the lifting ring B are quickly pulled down and further moved the bristles so that they rebound with their own elasticity to achieve self-cleaning work and shake off the dust. Dust will also be discharged along with the bristles on the inner wall of the connecting cover, and the air flow caused by the rotation of the fan blades will achieve rapid cutting work, and because the connecting cover is driven by the sliding sleeve to rotate quickly, the bristles adhered to the outer wall can be The residue is centrifugally thrown out and discharged through the square groove opened.

4. By setting up a cleaning mechanism, since the sliding round sleeve is fixedly connected to the internal threaded sleeve, and the connecting cover is slidingly connected to the inner wall of the sliding groove opened on the outer wall of the threaded rod, when the internal threaded sleeve rises, it will drive the sliding round sleeve to rotate synchronously. And the connecting cover is limited by the sliding groove and will not rotate but is pushed up by the internal thread sleeve, so that the sliding circular sleeve will drive the fan blades through the square to rotate and fan quickly, realizing rapid ventilation of the inner wall of the unloading pipe, and fixing the fit The dust dispersed by the rod and the dust dropped by the scraper and the scraper block are fully blown and dropped to realize the air flow inside the feeding tube, increase the dust falling effect, and reduce the dust adhesion problem.

5. By setting up a cleaning mechanism, the air and dust can achieve a certain degree of turbulence, causing the dust to collide with each other and become looser, thus avoiding the problem of metal powder falling and not being completely dried and adhering to each other, further improving the efficiency of powder drying. Ensure that it is dry, and at the same time, when the connecting cover is pushed up to the small fan blade, the small fan blade will be pushed into the sliding groove, causing the small fan blade to squeeze the elastic strip to deform, and drive the rotating shaft to move in the sliding groove The inner wall rotates and closes, thereby scraping the outer wall of the small fan blade by itself through the rising of the connecting cover. As the small fan blade closes, the inner wall of the sliding groove is also scraped, and the inner wall of the discharge pipe is lifted in all directions. The overall cleaning and self-cleaning effect ensures that it can fully disperse the metal dust that has been dried and discharged efficiently and stably for a long time.

Based on Embodiments 1 and 2, the present invention provides a technical solution: the cleaning mechanism 4 includes a block 401, and the outer wall of the block 401 is fixedly connected to the outer wall of the sliding sleeve 312. The outer wall of 401 is fixedly connected with a fan blade 402. The outer wall of the fan blade 402 is slidingly connected with a sliding sleeve 405. The outer wall of the sliding sleeve 405 is fixedly connected with an elastic rope 406. One end of the elastic rope 406 is fixedly connected with a lifting ring A407. The lifting ring A407 is fixedly connected with the outer wall. The outer wall of the column 408 and the connecting cover 313 is provided with a thin chute 410. The outer wall of the connecting column 408 is slidingly connected to the inner wall of the thin chute 410. The outer wall of the connecting column 408 is fixedly connected with a lifting ring B409.

A square groove 403 is formed on the outer wall of the connecting cover 313, and bristles 404 are fixedly connected to the inner wall of the connecting cover 313. A spring is fixedly connected to the bottom of the inner wall of the thin chute 410, and one end of the spring is fixedly connected to the bottom of the connecting column 408.

A magnet block 411 is fixedly connected to the top of the connection cover 313. The magnet block 411 itself has magnetism, and the lifting ring A407 itself has magnetism.

The magnetic bits on the opposite side of the lifting ring A407 and the magnet block 411 have opposite polarity attraction, and the width of the fan blade 402 is equal to the inner diameter width of the sliding groove 314 .

During use, different metal powders are poured into the powder processing machine 2, and after rapid drying, mixing and dispersion by hot air inside the powder processing machine 2, they are successively dropped through the bearing 301 at the bottom of the powder processing machine 2 and enter the base. 5 is collected in the stacking basin 10 above, and when falling through the unloading pipe 302, the motor 7 is started synchronously, and the motor 7 controls the gear A8 to rotate forward and reverse back and forth, driven by the meshing of the gear A8 and the gear B9 Gear B9 rotates synchronously with the feeding tube 302. The feeding tube 302 rotates rapidly on the bearing 301 at the bottom of the powder processing machine 2. When the feeding tube 302 rotates, the inner wall of the feeding tube 302 will contact with the scraper fixed by the square rod 303. The plate 304 slides and scrapes, so that when the metal powder falls through the inner wall of the bearing 301, it will quickly rotate through the inner wall of the unloading tube 302, and when the metal powder is scattered on the inner wall of the unloading tube 302, it will pass through the scraper 304 Contact and scrape it off quickly, fully cleaning the inner wall of the unloading pipe 302, and ensuring that the metal powder will fully fall and avoid the problem of dust accumulation due to residues, blocking the unloading pipe 302;

And as the rotation of the unloading pipe 302 drives the ring 305 on the inner wall of the unloading pipe 302 and the fixed rod 306 to rotate synchronously, the falling dust is scattered, and the threaded rod 307 is driven to rotate synchronously. Through the rotation of the threaded rod 307, The scraper 308 limited by the outer wall of the scraper 304 and the long connecting rod 309 limit the internal thread sleeve 310 synchronously, and the internal thread sleeve 310 is threadedly connected to the outer wall of the threaded rod 307, so that the internal thread sleeve 310 is restricted. When it cannot rotate, as the threaded rod 307 rotates, the internal thread sleeve 310 is driven to slowly rise through the thread rotation. When the internal thread sleeve 310 rises, it will simultaneously drive the long connecting rod 309 and the scraper 308 on the scraper 304. The outer wall slides from bottom to top, thereby cleaning the dust on the inner wall of the blanking pipe 302 by scraping the scraper 304 and the blanking pipe 302 to make it fall faster, and at the same time, the top is removed by the fixed rod 306. The falling dust is fully dispersed to ensure that the dust can fall evenly in the channel of the unloading pipe 302, thereby reducing the problem of a large amount of slipping and adhering to the inner wall of the unloading pipe 302, and the dust is further dispersed to make it more uniform. At the same time, the scraper 308 slides upward to fully wipe and clean the outer wall of the scraper 304, which avoids fully scraping off the residue adhered to the outer wall of the scraper 304 under the rotation of the unloading pipe 302 for a long time, and comprehensively Improve the cleaning effect of the outer walls of the discharge pipe 302 and the scraper 304, and ensure that the dust falling efficiency is not affected;

And when the internal thread sleeve 310 slides and rises on the outer wall of the threaded rod 307 as the thread rotates, it will simultaneously push the sliding circular sleeve 312 and the connecting cover 313 to rise, and because the sliding circular sleeve 312 and the internal threaded sleeve 310 are fixedly connected, the connecting cover 313 is slidingly connected to the inner wall of the sliding groove 314 opened on the outer wall of the threaded rod 307, so when the internal thread sleeve 310 rises, it will drive the sliding circular sleeve 312 to rotate synchronously, and the connecting cover 313 is limited by the sliding groove 314 and will not rotate. It is pushed up by the internal thread sleeve 310, so that the sliding circular sleeve 312 will drive the fan blade 402 through the block 401 to rotate and fan quickly, realizing rapid ventilation of the inner wall of the unloading pipe 302, and at the same time, the dust dispersed by the fixed rod 306 will be mixed with the material. The scraper 304 and the scraper block 308 scrape and impact the falling and floating dust to fully blow and fall, thereby realizing the air flow inside the unloading pipe 302, increasing the dust falling effect, and reducing the dust adhesion problem;

At the same time, the centrifugal force after the fan blade 402 rotates quickly throws out the sliding sleeve 405 on the outer wall of the fan blade 402, causing the sliding sleeve 405 to slide on the outer wall of the fan blade 402, and pulls the elastic rope 406 to deform, thereby causing the fan blade 402 to fan. While the air circulates, the fan blades 402 are further cleaned through the sliding sleeve 405. When the elastic rope 406 deforms to a certain extent, the elastic force is greater than the magnetic attraction between the lifting ring A407 and the magnet block 411, so the lifting ring A407 passes through the connecting column 408. The lifting ring B409 on the inner wall of the connecting cover 313 is driven to quickly separate from the magnetic attraction of the magnet block 411 and descend. As the connecting cover 313 rises, the bristles 404 on the inner wall of the connecting cover 313 clean the threaded rod 307 and at the same time, the threaded rod 307 is swept away. A large amount of dust is shaken off by the lowering of the lifting ring B409. Then, while the bristles 404 clean the threaded rod 307, the rotation of the fan blade 402 rapidly pulls the lifting ring A407 and the lifting ring B409 down to further clean the bristles. 404 is turned so that it rebounds with its own elasticity to achieve self-cleaning work. The dust shaken off by the movement will also be discharged with the bristles 404 provided on the inner wall of the connecting cover 313, and the air flow accompanied by the rotation of the fan blade 402 is achieved. Fast cutting operation, and because the connecting cover 313 is driven by the sliding sleeve 312 to rotate rapidly, the residue adhered to the outer wall of the bristles 404 can be centrifugally thrown out and discharged through the square groove 403 opened;

And when the threaded rod 307 rotates, the small fan blades 412 in the sliding groove 314 inside the threaded rod 307 will be thrown out along with the elastic force of the elastic strip 413, and stretch out to fan in a small range, so that the air in a small range can move. The flow causes the air flow inside the unloading pipe 302 to be fanned by the small fan blades 412 and 402, and is not a fixed and stable flow direction as a whole, causing the air and dust to achieve a certain degree of turbulence, causing the dust to collide with each other. It is looser and avoids the problem of metal powder falling and not being completely dried and sticking to each other, further improving the guarantee of powder drying, and at the same time, when the connection cover 313 is pushed up to the small fan blade 412, it will The small fan blade 412 is pushed into the sliding groove 314, which will cause the small fan blade 412 to squeeze the elastic strip 413 to deform, and drive the rotating shaft 414 to rotate and close on the inner wall of the sliding groove 314, thereby pushing the small fan blade 413 upward by itself through the connecting cover 313. The outer wall of the fan blade 412 is scraped, and as the small fan blade 412 is closed, the inner wall of the sliding groove 314 is also scraped, which comprehensively improves the overall cleaning and self-cleaning effect of the inner wall of the unloading tube 302, ensuring its It can effectively disperse the metal dust from drying and unloading for a long time and ensure the stability of the effect;

Since the motor 7 is in the working mode of continuous forward and reverse rotation, when it is about to reverse after rotating for a period of time, it will gradually decelerate, and after deceleration, the sliding sleeve 405 is pulled back by the elastic rope 406, and the connecting column 408 also It is pushed up by the spring on the inner wall of the thin chute 410, driving the lifting ring A407 and the lifting ring B409 to rise synchronously, thereby realizing the automatic return of the lifting ring A407. As it is about to start to reverse and accelerate, the sliding sleeve 405 will follow again. It is thrown out by centrifugal force and works reciprocatingly.

The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person familiar with the technical field can, within the technical scope disclosed in the present invention, implement the technical solutions of the present invention. Equivalent substitutions or changes of the inventive concept thereof shall be included in the protection scope of the present invention.
