Specifically, a rectangular slot 81 is defined on the upper side of the combination disk 8, and the limit block 7 is inserted into the rectangular slot 81. When the rotating disk rotates, it drives the column 61 to rotate, and then drives the rotating disk and the combination disk 8 to rotate synchronously. The combination disk 8 improves the stability of the forming disk 23 as the rotating disk rotates.

[0060] Side slots 71 are provided on both sides of the limit block 7, and inner slots 82 are provided on both sides of the combination disk 8. The inner slots 82 are connected to the rectangular slots 81. When the limit block 7 is inserted in the combination slot state, the side slots 71 can be connected to the inner slots 82. Positioning rods 9 are slidably connected in the two inner slots 82. Both positioning rods 9 can be snapped into the side slots 71 to limit the movement of the forming disk 23 in the vertical direction, so that when the upper drive cylinder 33 moves back and forth, the forming disk 23 can be stabilized at a certain height and will not shake due to the up and down sliding of the forming rod 41, thereby improving the tableting quality.

[0061] An extension slot 821 is provided above the inner slot 82. The extension slot 821 and the inner slot 82 extend in the same direction. A third spring 822 is provided within the extension slot 821. A slider 823 is fixed to the end of the third spring 822. The slider 823 is fixed to the positioning rod 9. Under normal circumstances, the third spring 822 can drive the positioning rod 9 to move toward the rectangular slot 81. A third inclined surface 91 is provided above the end of the positioning rod 9 that is close to each other. The third inclined surface 91 can quickly push the positioning rod 9 away when the limit block 7 is inserted into the rectangular slot 81, allowing the limit block 7 to be quickly inserted into the rectangular slot 81.

[0062] A vertical rod 92 is fixed to one end of each positioning rod 9 away from each other. A relief groove 624 is provided on the surface of the trigger plate 62. The vertical rod 92 can be inserted into the relief groove 624 in the vertical direction. A fourth inclined surface 921 is provided on one side of the vertical rod 92.

The vertical portion is fixed to the trigger plate 62, and the horizontal portion is fixed to the upper end of the vertical portion. The horizontal portion can abut against the fourth inclined surface 921. When the forming plate 23 needs to be disassembled, it is only necessary to move the trigger plate 62 downward. On the one hand, the downward movement of the trigger plate 62 can trigger the receiving member 4 and the connecting member 5 to lose the clamping restriction. On the other hand, the trigger plate 62 will drive the curved rod 625 downward, thereby pushing the fourth inclined surface 921, and then pushing the vertical rod 92 to move horizontally, driving the positioning rod 9 away from the rectangular groove 81, so that the limit block 7 can be disengaged from the combination plate 8, and the forming plate 23 can be quickly removed.

[0063] Reference Figure 1 The down-pressing assembly 3 includes a main drive cylinder 31, a square plate 32, and an upper drive cylinder 33. The main drive cylinder 31 is fixed to the upper side of the connecting plate 13. The telescopic rod of the main drive cylinder 31 is set downward and extends to the lower side of the connecting plate 13. The square plate 32 is fixed to the lower end of the telescopic rod of the main drive cylinder 31. A second servo motor 321 is fixed to the lower side of the square plate 32. The output shaft of the second servo motor 321 is set downward. A lower pressure plate 322 is fixed to the lower end of the second servo motor 321. A plurality of upper drive cylinders 33 are provided, and a plurality of upper drive cylinders 33 are fixed to the lower side of the upper pressure plate. The lower end of the telescopic rod of the upper drive cylinder 33 can be fixed with a pressure-formed part (not shown in the figure) corresponding to the shape of the forming hole 231. During operation, powder or granules can be loaded into the positioning hole, which is located above the positioning rod 9. The main driving cylinder 31 adjusts the position of the pressing component 3 in a large range. The second servo motor 321 and the first servo motor can rotate synchronously. The upper driving cylinder 33 presses down the powder in the positioning hole. After one rotation, the compaction is completed. The lower driving cylinder 22 works to drive the positioning rod 9 to move upward to push the compacted tablets out of the forming hole 231 to complete the tableting.

[0064] A support frame 323 is fixed on the lower side of the square plate 32, and an inclined push plate 324 and a blanking plate 325 are fixed below the support frame 323. Both the push plate 324 and the blanking plate 325 can abut against the forming disk 23, and a blanking area is formed between the push plate 324 and the blanking plate 325. During operation, the forming disc 23 rotates clockwise, and the powder hopper discharges the powder into the discharge area. When the forming hole 231 rotates to the discharge area, the powder falls into the forming hole 231. As the forming disc 23 rotates, the push plate 324 pushes the powder evenly into the forming hole 231. When the forming hole 231 rotates away from the discharge area, the upper drive cylinder 33 presses down to perform tableting. After tableting, the telescopic rod of the upper drive cylinder 33 moves upward to avoid the push plate 324 and the discharge plate 325. The telescopic rod of the lower drive cylinder 22 pushes upward, pushing the tablets above the forming disc 23. The discharge plate 325 pushes the tablets below the forming disc 23 to be collected by the discharge device. It should be noted that the hopper for holding the powder and the discharge device are both prior art and will not be described in detail in this application.

[0065] As an embodiment, two arc-shaped plates 326 are fixed between the pushing plate 324 and the blanking plate 325. The two arc-shaped plates 326, the pushing plate 324 and the blanking plate 325 can close the blanking area and concentrate the powder in a smaller area to facilitate the flow of the powder into the forming hole 231.

[0066] The implementation principle of the present invention is: when working, the forming disk 23 rotates clockwise, and the powder hopper can discharge the powder into the unloading area. When the forming hole 231 rotates to the unloading area, the powder can fall into the forming hole 231. As the forming disk 23 rotates, the pushing plate 324 can push the powder into the forming hole 231 evenly. When the forming hole 231 rotates away from the unloading area, the upper driving cylinder 33 presses down to perform tableting. After tableting, the telescopic rod of the upper driving cylinder 33 moves up to avoid the pushing plate 324 and the unloading plate 325. The telescopic rod of the lower driving cylinder 22 pushes up to push the tablets to the top of the forming disk 23. The unloading plate 325 can push the tablets to the bottom of the forming disk 23 and be collected by the unloading device.

[0067] When installing, the forming disk 23 can be installed from top to bottom. The upper sleeve 43 is sleeved in the insert block 52 from top to bottom. The upper sleeve 43 touches the first inclined surface 524, and the block 523 can be pushed into the receiving groove 521. When the groove 431 and the receiving groove 521 are connected, the first spring 522 pushes the block 523 out, and the block 523 can be stuck in the groove 431, completing the combination of the connecting member 5 and the receiving member 4; at the same time, the limit block 7 is clamped in the combination disk 8 to complete the installation of the forming disk 23.

[0068] When the forming disc 23 needs to be replaced, the pressing assembly 3 is first moved up to leave space for removal. Only the trigger disc 62 needs to be pressed to move the trigger disc 62 downward, which can push the trigger rod 213 to press the block 523, so that the block 523 is retracted into the security receiving groove 521. At this time, the trigger disc 62 will drive the bending rod 625 to move downward, thereby pushing the fourth inclined surface 921, and then pushing the vertical rod 92 to move horizontally, driving the positioning rod 9 away from the rectangular groove 81, so that the limit block 7 can be disengaged from the combination disc 8. At this time, only the forming disc 23 needs to be pulled up to quickly remove and clean the forming disc 23. After removal, a new forming disc 23 can be replaced in time for tableting to maintain the working efficiency of the tablet press.
