[0050] To be further described in detail: the metal sheet after pressing can be pressed down by the pressing assembly 900, so that the metal sheet can fall smoothly from the opening 620; the driving part 910 adopts a hydraulic cylinder, and the free end of the hydraulic cylinder drives the pressing column 920 to move downward into the inside of the tablet pressing cylinder 610, pressing the metal sheet downward, and the metal sheet falls from the opening 620 and is collected;

[0051] In addition, the three tablet pressing cylinders 610 always rotate around the center point of the array, and the rotation angle interval is 120°, so that among the three tablet pressing cylinders 610, one tablet pressing cylinder 610 always corresponds to the position of the pressing rod 400, another tablet pressing cylinder 610 always corresponds to the position of the pressing assembly 900, and the third tablet pressing cylinder can be used for loading.

[0052] Specifically, support legs are fixed at the four corners of the bottom end of the base 100 .

[0053] To further explain in detail: the supporting legs support the base 100 .

[0054] When the high-precision fully automatic tablet press of the embodiment of the present application is actually used: first, add an appropriate amount of metal powder into the inside of the tablet pressing barrel 610 close to the personnel, then start the driving member 636, the driving member 636 drives the rotating rod 634 to rotate, the rotating rod 634 drives the one-third side gear 635 to rotate clockwise, the one-third side gear 635 and the bar gear 633 are meshed, the bar gear 633 drives the rotating shaft 632 to rotate 120° counterclockwise, the rotating shaft 632 drives the connecting member 631 to rotate, the connecting member 631 synchronously drives the tablet pressing barrel 610 filled with metal powder to rotate 120° counterclockwise and move to the position of the next tablet pressing barrel 610, then start the hydraulic cylinder of the telescopic member, the free end of the hydraulic cylinder drives the tablet pressing barrel 610 to rotate counterclockwise, and the connecting member 631 drives the connecting member 631 to rotate counterclockwise. The rod 400 moves downward to press the tabletting cylinder 610 with metal powder below into tablets. At the same time, the tabletting cylinder 610 moved to the previous position is hollow and can continue to be fed. After the tabletting is completed, as the one-third side gear 635 rotates one circle, the connecting member 631 continues to drive the tabletting cylinder 610 to rotate 120° counterclockwise, and the tabletting cylinder 610 with the pressed metal sheet moves to the opening 620, and the metal sheet falls from the opening 620. At the same time, the metal powder in the tabletting cylinder 610 moved to the bottom of the telescopic member can be pressed into metal sheets by the hydraulic cylinder of the telescopic member. In this way, the synchronous operations of feeding, tableting and metal sheet unloading can be performed simultaneously, thereby improving the working efficiency.

[0055] When the metal sheets do not fall, the hydraulic cylinder of the driving part 910 can be started, and the free end of the hydraulic cylinder drives the pressing column 920 to move downward into the tablet pressing cylinder 610 to press the metal sheets downward, and the metal sheets fall from the opening 620 and are collected together.

[0056] When replacing other types of metal powder for pressing into sheets, the free end of the hydraulic cylinder of the telescopic part is moved up to a suitable height so that the bottom end of the pressing rod 400 corresponds to the top end of the scraping assembly 500, and then the power part 714 is started. The power part 714 drives the lead screw 713 to rotate, and drives the fixed plate 700 to move back and forth through the connecting block to scrape the metal powder at the bottom end of the pressing rod 400. Among them, the cleaning brush 510 cleans the metal powder, and the scraper 520 further scrapes the metal powder to scrape off the adhered metal powder to avoid the mixing of the two metal powders resulting in inaccurate composition.
