[0053] Specifically, when the support assembly 2 rotates, the driving motor 209 drives the rocker arm 207 to rotate, the rocker arm 207 drives the transmission rod 208 to rotate, so that the two transmission rods 208 are alternately inserted into the sliding groove 206, in the process, the transmission rod 208 extrudes the inner wall of the sliding groove 206, so that the transmission disc 205 rotates, in the process of inserting the transmission rod 208 into the sliding groove 206, the transmission rod 208 does not contact the inner wall of the sliding groove 206, when the transmission rod 208 moves to one end inside the sliding groove 206, the transmission rod 208 extrudes the inside of the sliding groove 206, at this time, the transmission disc 205 rotates, the transmission rod 208 and the sliding groove 206 can realize intermittent driving of the transmission disc 205, when the transmission disc 205 rotates, it can drive the rotating rod 204 to rotate, and the two rotating rods 204 are synchronously rotated through the driving wheel 210 and the driven wheel 211, at this time, the support assembly 2 can drive the lower die 3 and the upper die 4 to rotate respectively, at the same time, the driving wheel 210 drives the transmission wheel 505 to rotate through the transmission belt, so that the feeding assembly 5 can be driven.
[0054] When the lower die 3 and the upper die 4 coincide, the top block 306 is extruded upward by the lower pressing wheel 102, the top block 306 drives the movable rod 304 to move upward, the movable rod 304 drives the movable seat 303 to move upward, at the same time, the pressing block 404 is driven downward by the upper pressing wheel 103, the pressing block 404 drives the inserting rod 401 to move downward, the inserting rod 401 drives the pressing seat 402 to move downward, so that the pressing seat 402 is inserted into the forming seat 302, at this time, the pressing seat 402 cooperates with the movable seat 303 to complete the tabletting of the methylprednisolone tablets. After the tabletting of the methylprednisolone tablets is completed, the lower die 3 and the upper die 4 rotate with the support assembly 2, at this time, the top block 306 and the lower pressing wheel 102 are separated, the pressing block 404 and the upper pressing wheel 103 are separated, at this time, the limiting plate 305 and the positioning plate 403 are reset by the extrusion spring;
[0055] When the lower die 3 rotates to the upper side of the discharging wheel 104, the top block 306 is driven upward by the discharging wheel 104, the movable rod 304 is driven upward by the top block 306, and the movable seat 303 is driven upward by the movable rod 304. Since the height of the discharging wheel 104 is higher than that of the lower pressing wheel 102, the movable seat 303 has a larger movement range when it is at the position of the discharging wheel 104, so that the movable seat 303 is lifted to the upper side of the fixed seat 301. Then, the cleaning component sweeps the meloxicam tablets after being pressed and formed from the movable seat 303, and the swept meloxicam tablets are collected in the collecting device, so as to prepare for the next process.

When the feeding groove 506 on the discharging disc 503 rotates to the lower side of the feeding cover 507, the raw material powder falls into the feeding groove 506. When the feeding groove 506 rotates to the upper side of the discharging cover 508, the raw material in the feeding groove 506 can fall into the fixed seat 301 through the discharging cover 508, so as to complete the feeding of the raw materials. Embodiment 2
[0057] When the meloxicam tablets are pressed, the pressing quality of the tablets depends on the dryness, particle size and other factors of the meloxicam raw materials, and is also affected by the mutual extrusion effect of the movable seat 303 and the pressing seat 402. The extrusion effect of the movable seat 303 and the pressing seat 402 depends on the parameters of the extrusion spring, the extrusion effect between the lower pressing wheel 102 and the movable seat 303, the extrusion effect between the upper pressing wheel 103 and the pressing seat 402, etc. When the device is used for a long time, the extrusion spring is fatigued, or the lower pressing wheel 102, the movable seat 303, the upper pressing wheel 103 and the pressing seat 402 are worn, or the parameters of the meloxicam tablet raw materials are changed, the pressing quality of the meloxicam tablets is affected. Moreover, only one pressing is used, and the pressing time is short, so the quality of the tablets is also affected. Therefore, the internal structures of the movable seat 303 and the pressing seat 402 are further improved.

The pressure boosting piece 605 corresponding to the pressing block 404 is embedded in the upper end of the pressing seat 402 and the end face thereof is flush with the upper end face of the pressing seat 402.
[0059] The outer periphery of the top block 306 is provided with an arc-shaped structure in a hemispherical shape, and the other end of the pressure rod 601 corresponding thereto is flush with the lower end surface of the movable seat 303; the outer periphery of the pressure block 404 is provided with an arc-shaped structure in a hemispherical shape, and the other end of the pressure rod 601 corresponding thereto is flush with the lower end surface of the pressure block 404.
[0060] The outer periphery walls of the lower pressing wheel 102, the upper pressing wheel 103 and the discharging wheel 104 are uniformly provided with a plurality of extrusion blocks 606, and the extrusion blocks 606 on the upper pressing wheel 103 and the pressure blocks 404 correspond to each other, when the pressure block 404 moves directly below the upper pressing wheel 103, the extrusion block 606 can extrude the pressure rod 601 in the corresponding pressure block 404. Similarly, the extrusion blocks 606 on the lower pressing wheel 102 and the discharging wheel 104 correspond to the top blocks 306, when the top block 306 moves directly above the lower pressing wheel 102 or the discharging wheel 104, the extrusion block 606 can extrude the pressure rod 601 in the corresponding top block 306.
[0061] In the process of pressing the methylprednisolone tablets, the upper pressing wheel 103 first extrudes the arc-shaped outer periphery of the pressure block 404, and then extrudes the upper end surface of the pressure block 404, at the same time, the lower pressing wheel 102 first extrudes the arc-shaped outer periphery of the top block 306, and then extrudes the lower end surface of the top block 306; in this process, the pressure block 404 moves downward, the top block 306 moves upward, and then the raw material powder is first extruded and formed by the corresponding pressure tablet 605 of the pressure block 404, the lower end surface of the pressure seat 402, the corresponding pressure tablet 605 of the top block 306 and the upper end surface of the movable seat 303, completing the preliminary forming and preliminary compaction of the methylprednisolone tablets. With the forward movement of the top block 306 and the pressure block 404, when the top block 306 moves directly above the lower pressing wheel 102, the pressure block 404 also moves directly below the upper pressing wheel 103, at this time, the extrusion block 606 on the lower pressing wheel 102 extrudes the pressure rod 601 in the top block 306, making the pressure rod 601 move upward, at the same time, the extrusion block 606 on the upper pressing wheel 103 extrudes the pressure rod 601 in the pressure block 404, making the pressure rod 601 move downward; further, the upper and lower pressure rods 601 respectively drive the upper and lower pressure tablets 605 to move close to each other, and the methylprednisolone tablets preliminarily formed after the first extrusion are secondarily extruded and formed, improving the extrusion forming effect of the methylprednisolone tablets. After completing the secondary extrusion forming, when the corresponding top block 306 leaves the lower pressing wheel 102, the pressure rod 601 and the corresponding pressure tablet 605 are reset under the resetting action of the reset spring 602; similarly, when the corresponding pressure block 404 leaves the upper pressing wheel 103, the pressure rod 601 and the corresponding pressure tablet 605 are reset under the resetting action of the reset spring 602, preparing for the next pressing.
[0062] In particular, by setting the size of the booster tablets 605, the upper booster tablet 605 is smaller than the lower end surface of the pressure seat 402 (in actual operation, the upper booster tablet 605 is slightly smaller than the lower end surface of the pressure seat 402, for example, the diameter of the pressure seat 402 is 8 mm, and the diameter of the upper booster tablet 605 is 5 mm), and the lower booster tablet 605 is smaller than the upper end surface of the movable seat 303 (in actual operation, the lower booster tablet 605 is slightly smaller than the lower end surface of the movable seat 303, for example, the diameter of the movable seat 303 is 8 mm, and the diameter of the lower booster tablet 605 is 5 mm). In this way, on the one hand, the upper and lower booster tablets 605 and the upper end surface of the movable seat 303 and the lower end surface of the pressure seat 402 can jointly perform primary extrusion molding on the raw material powder. Then, on the basis of the primary extrusion molding, the booster rod 601 is extruded by the corresponding extrusion block 606, so that the booster rod 601 drives the booster tablet 605 to move, and the primary extrusion molded methylprednisolone tablets are subjected to secondary extrusion molding, thereby improving the compactness of the extruded methylprednisolone tablets and further improving the molding quality of the methylprednisolone tablets. After the pressure block 404 leaves the upper pressure wheel 103 and the top block 306 leaves the lower pressure wheel 102, under the resetting action of the reset spring 602, the booster rod 601 and the corresponding booster tablet 605 are reset. In this process, since the booster tablet 605 and the lower end surface of the pressure seat 402 have moved relative to each other (i.e., the booster tablet 605 is retracted into the pressure seat 404), if the tablets adhere to the booster tablet 605 due to extrusion, when the booster tablet 605 is retracted into the pressure seat 404, the tablets adhering to the booster tablet 605 can be separated under the support of the pressure seat 402, thereby reducing the problem that the tablets adhere to the booster tablet 605 due to secondary extrusion, which is not conducive to subsequent collection of the tablets. Similarly, since the booster tablet 605 and the upper end surface of the movable seat 303 have moved relative to each other (i.e., the booster tablet 605 is retracted into the movable seat 303), if the tablets adhere to the booster tablet 605 due to extrusion, when the booster tablet 605 is retracted into the movable seat 303, the tablets adhering to the booster tablet 605 can be separated under the support of the movable seat 303, thereby reducing the problem that the tablets adhere to the booster tablet 605 due to secondary extrusion, which is not conducive to subsequent collection of the tablets. Example 3
[0063] Further, the height of the extrusion block 606 on the discharging wheel 104 is greater than the height of the extrusion block 606 on the lower pressing wheel 102 and the upper pressing wheel 103. Thus, after the methylprednisolone tablet in the movable seat 303 is extruded, when the top block 306 moves to the discharging wheel 104, the arc surface of the top block 306 first contacts the discharging wheel 104, and then the lower end surface of the top block 306 contacts the discharging wheel 104. In this process, the top block 306 is extruded upward by the discharging wheel 104, so that the top block 306 drives the movable rod 304 to move upward, and the movable seat 303 is lifted to the outside of the fixed seat 301, so as to prepare for the subsequent cleaning component to sweep the pressed methylprednisolone tablet from the movable seat 303. Further, as the top block 306 moves gradually, when the top block 306 moves to the position directly above the extrusion block 606 of the discharging wheel 104, the extrusion block 606 extrudes the booster rod 601 in the top block 306, so that the booster rod 601 moves upward, and the booster rod 601 drives the booster piece 605 to move upward. Since the height of the extrusion block 606 on the discharging wheel 104 is greater than the height of the extrusion block 606 on the lower pressing wheel 102 and the upper pressing wheel 103, the height of the upward movement of the booster piece 605 is higher than the height of the second extrusion piece, so that the second extrusion piece above the movable seat 303 is lifted upward, the second extrusion piece is separated from the movable seat 303, the second extrusion piece is prevented from being adhered to the movable seat 303 due to excessive extrusion force, the second extrusion piece is prevented from being damaged when the subsequent cleaning component cleans it, and the quality of the tablet product is ensured. The discharging wheel 104 (not shown in the figure) is also arranged on the other side of the support frame 101, and is used to clean the tablet adhered to the lower end surface of the pressing seat 402 (because in actual production, due to the second extrusion and the influence of the moisture of the material, a small amount of tablet will be adhered to the lower surface of the pressing seat 402). When the pressing seat 404 moves to the position directly below the extrusion block 606 of the discharging wheel 104, the extrusion block 606 extrudes the booster rod 601 in the pressing seat 404, so that the booster rod 601 moves downward, and the booster rod 601 drives the booster piece 605 to move downward. Since the height of the extrusion block 606 on the discharging wheel 104 is greater than the height of the extrusion block 606 on the lower pressing wheel 102 and the upper pressing wheel 103, the height of the downward movement of the booster piece 605 is lower than the height of the second extrusion piece, so that the second extrusion piece above the pressing seat 402 is lifted downward, the second extrusion piece is separated from the pressing seat 402, the second extrusion piece is prevented from being adhered to the pressing seat 402 due to excessive extrusion force, the second extrusion piece is prevented from being damaged when the subsequent cleaning component cleans it, and the quality of the tablet product is ensured.
