on the basis, the blanking method comprises the following steps,
a. scraping and conveying
The driving unit drives the rotating shaft 3 to rotate, the first scraper 5 rotates under the driving of the rotating shaft, the first scraper 5 scrapes and conveys materials when rotating, and the materials can circularly move around the rotating shaft along with the scraping and conveying of the first scraper 5;
b. discharging
When the material is moving around pivot 3, the centrifugal force that produces when rotating with the help of first scraper blade 5 moves to the edge by the middle part of the storehouse body 2, and the material moves to the edge of the storehouse body 2, falls perpendicularly when through discharge gate 1, realizes the ejection of compact.
The drive unit is the motor, motor drive pivot 3 rotates, pivot 3 drives cantilever 4 and carries out anticlockwise rotation, then, first scraper blade 5 rotates scrapes the material and send, when scraping and sending, the material can move towards storehouse body 2 lateral wall direction, fall down perpendicularly when the material passes through discharge gate 1, realize the ejection of compact of material, the material relies on first scraper blade 5 initiative to scrape and send, need not to rely on the gravity of material itself to carry out the ejection of compact, further avoid the emergence of putty phenomenon, and simultaneously, first scraper blade 5 still can play the effect of stirring to the material when scraping and sending the material, especially to powdery material, avoid the caking of powdery material, block up discharge gate 1 when the ejection of compact, storehouse body 2 adopts tubbiness structure, it is more convenient when scraping and sending at first scraper blade 5, and scrape the more thoroughly who sends, avoid appearing scraping and send the dead angle, cause the problem of material siltation in storehouse body 2, discharge gate 1 sets up in one side of storehouse body 2 bottom, first scraper blade 5 scrapes the material when sending to discharge gate 1, the material is automatic to cause the direct perpendicular falling down from discharge gate 1, avoid the problem of the easy putty of traditional taper structure.
As shown in fig. 2, the first scraper 5 is horizontally and obliquely arranged at the lower end of the cantilever 4, and the inclination direction of the end of the first scraper 5 away from the rotating shaft 3 is opposite to the rotating direction of the rotating shaft 3.
The first scraper blade 5 that the slope set up can scrape the material faster by 2 centers in the storehouse body to the lateral wall direction and send, scrapes and send efficiency higher, improves after scraping the speed of sending, makes scraping of material send the volume to be greater than the discharge gate 1's load, makes the material form with the help of scraping the reasoning of sending and rolls, realizes the secondary stirring of material, and especially powder can be with the powder stirring of mixing more even, can also break up the powder of caking.
As shown in fig. 2, the scraping and conveying unit further comprises a second scraping plate 6, one end of the second scraping plate 6 is fixed on the side surface of the rotating shaft 3, and the upper end of the second scraping plate 6 is attached to the lower end of the cantilever 4;
the blanking method also comprises the following steps of,
c. the material in the middle of the bin body 2 is scraped outwards by the second scraper 6.
Near the position of pivot 3 is first scraper blade 5 scrapes and send the dead angle, can the silting partial material around pivot 3, so scrape the material around the pivot 3 through setting up second scraper blade 6 and send, second scraper blade 6 scrapes the material around the pivot 3 and send the scope of scraping to first scraper blade 5, first scraper blade 5 is scraping the material and sending to discharge gate 1 and carry out the ejection of compact, avoid the material to remain in storehouse body 2, the not thorough problem of the ejection of compact has been solved, and can further improve stirring effect.
As shown in fig. 2, the second scraper 6 is disposed obliquely and has the same inclination direction as the first scraper 5, and the inclination angle of the second scraper 6 is larger than that of the first scraper 5.
The second scraper blade 6 is scraped the scope of sending of scraping of material around 3 pivots to first scraper blade 5 and is sent, first scraper blade 5 is scraped and is sent the scope big, it is many to scrape the material of sending, it is big to scrape the resistance of sending, second scraper blade 6 is scraped and is sent the scope little, it is few to scrape the material of sending, it is less to scrape the resistance of sending, so strengthen the inclination of second scraper blade 6, accelerate the speed that second scraper blade 6 scraped the material to the outside and sent, reduce the inclination of first scraper blade 5, slow down the speed that the outside that the material scraped under sending at first scraper blade 5 removed, avoid scraping and send the material that causes at discharge gate 1 dwell time short at the excessive speed, reduce discharging efficiency's problem.
As shown in fig. 2, the first squeegee 5 forms an angle of 20 ° to 70 ° with the cantilever 4.
The inclination angle of the first scraper 5 is set to be 20-70 degrees, so that the efficiency of scraping the materials outwards by the first scraper 5 is higher.
As shown in fig. 2, the number of the cantilevers 4 is not less than three, and the cantilevers 4 are uniformly distributed on the outer circumference of the rotating shaft 3.
Set up the cantilever 4 of no less than three groups, be no less than three first scraper blade 5 of group and second scraper blade 6 promptly, the quantity of cantilever 4, first scraper blade 5 and second scraper blade 6 is too little to cause scrapes and send the resistance too big, the damage of cantilever 4 and scraper blade appears easily, can not play better stirring effect moreover.
