DETAILED DESCRIPTION

[0022] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0023] See also Figures 1 to 3 A tablet pressing device includes a rectangular bottom plate 1, a first bracket 2 is provided at the upper end of the bottom plate 1, the first bracket 2 is composed of two vertical plates, a rectangular lower receiving plate 3 is horizontally fixed in the middle of the first bracket 2, a rectangular pressing plate 10 is horizontally fixed on the top of the first bracket 2, a mold cavity 12 penetrating up and down is vertically opened at the center of the pressing plate 10, a through hole 4 is vertically opened at the center of the lower receiving plate 3, a horizontal circular lower mounting plate 7 is placed on the lower receiving plate 3 above the through hole 4, and a lower top column 9 for sliding into the mold cavity 12 is fixed at the center of the top of the lower mounting plate 7. Two sliding holes 11 are also vertically opened upward at the bottom of the pressing plate 10, and the two sliding holes 11 are symmetrically distributed with the mold cavity 12 as the center, and two sliding rods 8 are also vertically fixed at the upper end of the lower mounting plate 7, and the sliding rods 8 are used to slide into the sliding holes 11 in a one-to-one corresponding manner.

[0024] When the above solution is used, when the lower mounting plate 7 abuts against the lower receiving plate 3 , the lower ejector column 9 is in the mold cavity 12 , the slide bar 8 is in the slide hole 11 , and the top of the slide bar 8 is lower than the top of the lower ejector column 9 .

[0025] The bottom plate 1 is also provided with a first electric push rod 5, and the top of the telescopic rod of the first electric push rod 5 is provided with a top block 6, and the top of the top block 6 is a horizontal surface. The telescopic rod and the top block 6 pass through the through hole 4 and abut against the bottom of the lower mounting plate 7, so that the lower mounting plate 7 moves up and down.

[0026] When the above scheme is used, when the upper push column 24 is pressed into the mold cavity 12 to press the tablet, the lower mounting plate 7 and the lower receiving plate 3 are against each other, thereby giving support force to the lower push column 9. When the tablet is pressed, the telescopic rod of the first electric push rod 5 extends upward, and the top block 6 pushes the lower mounting plate 7, lifting the lower mounting plate 7, so that the lower push column 9 moves up in the mold cavity 12. At this time, the extension amount of the telescopic rod of the first electric push rod 5 is set so that the top of the lower push column 9 exceeds the upper end surface of the pressing plate 10 by 0 to 0.5 mm, so that the tablet is completely ejected from the mold cavity 12, preparing for the next step of the tablet to leave the airspace above the mold cavity 12. By setting the non-connective contact between the first electric push rod 5 and the lower mounting plate 7, the assembly of the first electric push rod 5 and the lower mounting plate 7 is simpler to prevent the lower push column 9 from being offset and stuck with the mold cavity 12 when the first electric push rod 5 is tilted.

[0027] Four support columns 13 are provided at the upper end of the pressing plate 10, and the four support columns 13 are distributed along the sides of the virtual rectangle, preferably, distributed at the four corners of the virtual rectangle. A rectangular upper receiving plate 20 is fixed on the top of the support column 13. A through hole 21 is vertically opened downward at the center of the upper receiving plate 20 directly above the mold cavity 12, and the size and shape of the through hole 21 are the same as those of the mold cavity 12. Two rectangular support plates 22 are fixed opposite to each other above the upper receiving plate 20, and the opposite sides of the two support plates 22 are vertically opened with a slide groove 25, and the two side walls of the upper mounting plate 26 protrude outward to form a slider 27 that matches the slide groove 25, and the upper mounting plate 26 is slidably connected in the slide groove 25 of the two support plates 22 through the sliders 27 on both sides so as to slide up and down. An upper pillar 24 for slidingly inserting into the through hole 21 and the mold cavity 12 is fixedly provided at the bottom of the upper mounting plate 26 . A spring 23 is also sleeved on the outer side of the upper pillar 24 . The top of the spring 23 is connected to the upper mounting plate 26 , and the bottom of the spring 23 is connected to the upper receiving plate 20 .

[0028] When the above solution is used, when the spring 23 is not subjected to any external force except the upper mounting plate 26 , the upper push column 24 is located in the through hole 21 .

[0029] A third bracket 29 is also provided at the upper end of the bottom plate 1, a cross frame 30 is fixed on the third bracket 29, and a third electric push rod 28 is fixed on the cross frame 30. The bottom of the telescopic rod of the third electric push rod 28 abuts against the top of the upper mounting plate 26 to move the upper mounting plate 26 up and down.

[0030] When the above solution is used, the depth of the upper push column 24 inserted into the mold cavity 12 is controlled by setting the extension amount of the telescopic rod of the third electric push rod 28. When tableting is required, the telescopic rod of the third electric push rod 28 extends downward to push the upper mounting plate 26 downward, and the upper mounting plate 26 pushes the lower push column 9 downward to be inserted into the mold cavity 12 for tableting. When tableting is completed, the telescopic rod of the third electric push rod 28 retracts upward, and the upper mounting plate 26 moves upward under the reset action of the spring 23, so that the upper push column 24 is separated from the mold cavity 12 and returns to the through hole 21.

[0031] By designing a separate pushing structure for the third electric push rod 28 and the upper mounting plate 26, the installation and debugging of the third electric push rod 28 when driving the upper mounting plate 26 is simpler. Even if the telescopic rod of the third electric push rod 28 is slightly offset at an angle, it will not affect the downward movement of the upper push column 24, thereby avoiding damage to components due to offset movement.

[0032] A drug inlet pipe 31 is obliquely inserted into the upper receiving plate 20, and the lower end of the drug inlet pipe 31 extends to the lower end of the upper receiving plate 20 and points to the mold cavity 12.

A quantitative dosing mechanism is also provided on the support plate 22, and the quantitative dosing mechanism includes a drug storage hopper 33 fixed on the support plate 22, and the bottom of the drug storage hopper 33 is also connected to a solenoid valve 32, and the upper end of the drug inlet pipe 31 is connected to the solenoid valve 32.

[0033] When using the above solution, the medicine powder is added to the medicine storage hopper 33 in advance. When the medicine powder needs to be added to the mold cavity 12, the solenoid valve 32 is opened, and the medicine powder flows out from the medicine inlet pipe 31 and is sprayed obliquely under the action of gravity into the mold cavity 12. When the medicine powder exceeds the mold cavity 12, the solenoid valve 32 is closed.

[0034] A second bracket 17 is also fixedly provided on the base plate 1, and a second electric push rod 18 is fixedly provided on the second bracket 17. The telescopic rod of the second electric push rod 18 is horizontally telescopic, and a push plate is fixedly provided at the end. The push plate includes a hard plate 19 and a soft scraper strip 34. The hard plate 19 is provided above the soft scraper strip 34, and the hard plate 19 is connected to the telescopic rod of the second electric push rod 18. The bottom of the soft scraper strip 34 slides against the upper end surface of the die plate 10, and the movement trajectory of the push plate covers the mold cavity 12. When the push plate is farthest from the second electric push rod 18, the side wall of the push plate is flush with the side wall of the die plate 10 or exceeds the side wall of the die plate 10, and preferably, exceeds the side wall by less than 1 mm.

[0035] When the above solution is used, after the powder is supplied, the second electric push rod 18 is started, and the second electric push rod 18 pushes the scraper to scrape over the top of the mold cavity 12, flattens the powder beyond the mold cavity 12, and then the scraper returns to its position. After the tableting is completed and the tablet is lifted out by the lower push column 9, the second electric push rod 18 pushes the push plate again to push the tablet to the edge of the pressing plate 10.

[0036] A screen frame 14 is obliquely provided on the side wall of the pressing plate 10 , a recovery container 16 is provided on the bottom plate 1 just below the screen frame 14 , a medicine receiving plate 15 is horizontally provided at the lowest point of the screen frame 14 , and the telescopic rod of the second electric push rod 18 is telescopic toward the screen frame 14 .

[0037] When using the above solution, excess powder and tablets are pushed onto the screen frame 14, the powder passes through the screen in the screen frame 14 and falls into the recovery container 16, and the tablets slide along the screen frame 14 to the medicine receiving plate 15, waiting to be collected by the operator.

[0038] The device is also provided with a controller, which adopts an STM32 single-chip microcomputer or a SMART200 PLC controller, and the first electric push rod 5, the second electric push rod 18, the third electric push rod 28 and the electromagnetic valve 32 are all electrically connected to the controller. Through the controller, the above-mentioned electrical components can be simply programmed with one-key operation, such as setting the one-key opening time of the electromagnetic valve 32, setting the one-key first pressing down and then rising operation of the third point push rod, setting the first rising and then falling operation of the first electric push rod 5, setting the one-key short stroke back and forth powder scraping operation of the second push rod, and the one-key long stroke back and forth medicine pushing operation.
