[0039] Among them, the spring 1 725 is used for resetting the top tube 1 721 after it moves, and the spring 1 725 always pulls the top tube 1 721 upward, and the interior of the top tube 1 721 is used for storing medicine powder.

[0040] The medicine feeding part 73 includes a transmission rod 731, a plugging head 732, a stirring blade 733, an annular frame 734 and a second spring 735. The transmission rod 731 is located on the inner side of the top cylinder 721, the plugging head 732 is fixedly arranged at the end of the transmission rod 731, the plugging head 732 passes through and is slidably arranged on the inner side of the top cylinder 722, the stirring blade 733 is fixedly arranged on the side of the transmission rod 731, the annular frame 734 is fixedly arranged on the inner side of the top cylinder 721, the two ends of the second spring 735 are respectively fixedly arranged on the top of the annular frame 734 and the side of the transmission rod 731, and the transmission rod 731 is slidably arranged on the inner side of the annular frame 734.

[0041] Among them, there are multiple groups of stirring blades 733, each group of stirring blades 733 is provided with multiple stirring blades and fixedly set on the side of the transmission rod 731, which can move the powder when the transmission rod 731 slides up and down to prevent the powder from being blocked inside the top tube 721; the spring 2 735 always pulls the transmission rod 731 upward.

[0042] The boss member 74 includes boss one 741, boss two 742 and boss three 743. Boss one 741 is fixedly arranged on the bottom side of the top of the support frame 2, boss two 742 is fixedly arranged on the inner side of boss one 741, boss three 743 is fixedly arranged on the top of the base 1, the top of the transmission rod 731 is slidably arranged on the bottom of boss one 741, the pulley 727 is rollingly arranged on the bottom of boss two 742, and the top ball 728 is slidably arranged on the top of boss three 743.

[0043] Among them, the sides of boss 1 741, boss 2 742 and boss 3 743 are all provided with protrusions of inconsistent heights. The protrusions of boss 1 741 and boss 2 742 have four stages, ABCD, respectively, while boss 3 743 has only two stages, EF. The function of these protrusions is to control the lifting and lowering of transmission rod 731, top cylinder 1 721 and top cylinder 2 723, thereby achieving the purpose of pressing tablets, replenishing powder and ejecting finished tablets.

[0044] During use: In the prior art, the medicine powder is directly placed on the rotating table 711, and then when the rotating table 711 rotates, the medicine powder is automatically filled into the pressing hole 714, but the medicine powder will always spread on the surface of the rotating table 711, which is easy to cause waste and is unhygienic. The tablet press of this invention places the medicine powder inside the top cylinder 721, and when the top cylinder 721 rotates with the rotating disk 1 712, the medicine powder is released in the closed space formed by the top head 1 722, the top head 2 724 and the pressing hole 714, thereby avoiding the waste of medicine powder.

[0045] Before starting the machine, fill the powder into each top cylinder 721 respectively, and then start the motor 3, which drives the driving shaft 4 to rotate, and the driving shaft 4 drives the rotating table 711 and the rotating disk 1 712 and the rotating disk 2 713 to rotate. Driven by the rotating disk 1 712 and the rotating disk 2 713, the top cylinder 1 721, the top cylinder 2 723 and the transmission rod 731 interact with each boss.

[0046] In stage A, under the extrusion of boss 1 741 and boss 2 742, the top head 1 722 is partially immersed in the pressing hole 714, and the plugging head 732 is flush with the top head 1 722. Then, in stage B, under the action of the protrusion of boss 2 742, the height of the top cylinder remains unchanged, while boss 1 741 is concave, and the transmission rod 731 rises under the action of spring 2 735, so that the plugging head 732 slides out of the top head 1 722 and a certain gap is generated, and the powder falls from the gap inside the plugging head 732 and the top head 1 722 to the top end surface of the top cylinder 2 723.

[0047] As the drive shaft 4 rotates, the top cylinder 1 721 reaches the C stage, and the protrusions of the boss 1 741 and the boss 2 742 deepen, so that the transmission rod 731 and the top cylinder 1 721 descend at the same time, and the plug 732 of the transmission rod 731 slides back into the inside of the top head 1 722 and the end surface is restored to be flush. During the process of the top cylinder 1 721 descending, the plane formed by the plug 732 and the top head 1 722 suppresses the falling medicine powder by the end surface of the top head 2 724, and presses the medicine powder into tablets. Finally, in the D stage, the protrusions of the boss 1 741 and the boss 2 742 become shallow at the same time, and the top cylinder 1 721 and the transmission rod 731 rise at the same time, and finally the top head 1 722 is higher than the thickness of the inclined rod 6 under the pull of the spring 1 725.

[0048] At the same time, in the ABC stages, the top cylinder 2 723 at the corresponding position of the top cylinder 1 721 is in the E stage, that is, the top head 2 724 is partially inside the pressing hole 714, and in the D stage, the top cylinder 2 723 is in the F stage, and the end face of the top head 2 724 is lifted upward to the level with the top surface of the rotating table 711 under the support of the protrusion of the boss 3 743. At this time, as the rotating table 711 rotates, the tablets are stuck on the side of the inclined rod 6 and are gradually pushed into the medicine storage box 5 when the rotating table 711 rotates.

[0049] When the top cylinder 1 721 rotates with the rotating disk 1 712, under the action of the protrusions of the boss 1 741 and the boss 2 742, the plugging head 732 and the top head 1 722 are separated, so that the medicine powder is released in the closed space formed by the top head 1 722, the top head 2 724 and the pressing hole 714, thereby avoiding the waste of medicine powder. The medicine powder is always inside the top cylinder 1 721, avoiding contact with the outside world, which is more hygienic and convenient for subsequent cleaning.

[0050] The remaining structures are the same as those of Example 1.

[0051] Reference Figure 3~Figure 7 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the vibration member 81 includes a concave-convex disk 811, a top shaft 812, and a loose rod 813. The concave-convex disk 811 is fixedly arranged on the inner side of the boss three 743, the top shaft 812 is slidably arranged on the inner side of the top tube two 723, the loose rod 813 is fixedly arranged on the end of the top shaft 812 located on the inner side of the top tube two 723, and the end of the top shaft 812 away from the top tube two 723 is slidably arranged on the top surface of the concave-convex disk 811.

[0052] Among them, there are multiple loose rods 813 and they are evenly arranged on the end surface of the top shaft 812; the concave-convex disk 811 is avoided to be provided with a plurality of protrusions, and when the top shaft 812 slides on the surface of the concave-convex disk 811, it will rise and fall.

[0053] The limiting member 82 includes a conical platform 821 and a push rod 822. The conical platform 821 is sleeved and fixedly arranged on the side of the transmission rod 731. The push rod 822 is fixedly arranged on the inner side of the top tube 721. The push rod 822 is located directly below the conical platform 821.

[0054] Among them, there are multiple push rods 822, which are evenly surrounded on the surface of the top tube 721. When the bottom of the conical platform 821 and the push rod 822 are in contact, the end face of the plugging head 732 and the end face of the top head are exactly flush. Only after the two are flush can the tablets be pressed; when the powder slides off the edge of the conical platform 821, the powder falls from around the spring 2 735 to avoid the powder accumulating inside the spring 2 735.

[0055] During use: when the top cylinder 2 723 rotates following the rotating disk 2 713, the top shaft 812 continuously rises and falls under the support of the concave-convex disk 811, and in stage E, when the top shaft 812 is lifted, the scattering rod 813 can hit the inner wall of the top cylinder 2 723, causing the top cylinder 2 723 to vibrate, so that the medicine powder can be evenly distributed on the surface of the top head 2 724, making the tablets more compact.

[0056] After the push rod 822 of the limit member 82 cooperates with the conical platform 821, the transmission rod 731 can be lifted upward, but when descending, it can only be lowered to the level where the end faces of the plugging head 732 and the top head 724 are flush, to prevent the end face of the plugging head 732 from exceeding the top head 724 after the raised surface of the boss 2 742 is worn, resulting in a pressing failure.

[0057] The remaining structure is the same as that of Example 2.
