[0028] When the tablet press is working, the fan 12 is started, and the fan 12 generates suction to attract the powder floating around the tablet press, and the floating powder is sucked in through the suction hood 15 to ensure that no powder is scattered into the working environment during the tablet pressing process. Then, the collected powder is conveyed to the inside of the collection box 9 through the conveying pipe 14. The collection box 9 is equipped with a transparent window 27, and the operator can observe the collection of the powder inside the collection box 9 in real time through the transparent window 27. The transparent window 27 allows the operator to determine the amount of powder collected without opening the collection box 9, and make judgments and adjustments in time. When the transparent window 27 shows that the collection box 9 is full, the operator can pull the drawer 10 out of the collection box 9 to recycle the collected tablet powder, which can avoid the waste of raw materials, reuse the collected powder in the production process, and significantly reduce the production cost. The filter plate 13 is provided to facilitate the filtration of the powder inside the collection box 9. Avoid the suction of the fan 12 and extend the service life of the fan 12.
[0029] Reference Figure 5 and Figure 6 A mounting cavity 20 is provided inside the mounting block 17, a slider 21 is slidably connected inside the mounting cavity 20, a connecting rod 22 is fixedly connected to the left side of the outside of the slider 21, a handle 24 is fixedly connected to the outside of the connecting rod 22, an insertion rod 25 is fixedly connected to the right side of the outside of the slider 21, a spring 28 is sleeved on the outside of the connecting rod 22, a socket 26 is provided inside the mounting column 19, the insertion rod 25 is slidably connected to the inside of the socket 26, a through hole 23 is provided outside the mounting block 17, and the connecting rod 22 is slidably connected to the inside of the through hole 23.
[0030] When it is necessary to replace a different lower mold 18, the operator first pulls the handle 24 and pulls it outward along the track designed for the equipment. The movement of the handle 24 drives the connecting rod 22 to move together. The connecting rod 22 is fixed to the outside of the handle 24. When the handle 24 is pulled, the connecting rod 22 also moves. This movement drives the slider 21 fixed to the outside of the connecting rod 22 to move laterally inside the mounting cavity 20. During the movement of the slider 21, the plug rod 25 fixed to the outside of the slider 21 also moves, while compressing the spring 28 sleeved on the outside of the connecting rod 22. At this time, the plug rod 25 will gradually detach from the inside of the socket 26. When the plug rod 25 is completely detached from the socket 26, the mounting column 19 and the lower mold 18 can be taken out from the inside of the mounting block 17. At this time, the operator can easily remove the lower mold 18 and prepare to install a new lower mold 18, insert the new lower mold 18 and the mounting column 19 into the interior of the mounting block 17, ensure that they are correctly positioned, and the operator releases the handle 24. Under the reaction force of the spring 28, the insertion rod 25 automatically returns to its original position and inserts into the interior of the insertion hole 26. In this way, the newly installed lower mold 18 and the mounting column 19 are firmly fixed in the mounting block 17, completing the mold replacement process. The tablet compression device is convenient for replacing different lower molds 18, so that the device can adapt to the production of tablets of different specifications and shapes, meet diverse market demands, and improve the applicability of the device.
[0031] Reference Figure 1 and Figure 2 The compression assembly 3 includes a cylinder 301, which is fixedly connected to the inside of the mounting plate 2. The output end of the cylinder 301 is fixedly connected to a movable plate 302. The lower part of the movable plate 302 is fixedly connected to a connecting rod 303. The lower part of the connecting rod 303 is fixedly connected to an upper mold 304. Both sides of the inside of the mounting plate 2 are fixedly connected to telescopic rods 4. The tops of the two telescopic rods 4 are fixedly connected to the upper sides of the movable plate 302.
[0032] When compressing the tablet, the tablet powder enters the interior of the lower mold 18 through the discharge port 7, and then the hydraulic cylinder is started to drive the upper mold 304 to move downward, initially contacting the tablet powder in the lower mold 18, and the upper mold 304 applies a small initial pressure to pre-compress the powder. The purpose of pre-compression is to exhaust the air in the powder and preliminarily shape the powder. After the pre-compression is completed, the upper mold 304 is slightly lifted to relieve the pressure so as to enter the next compression stage. The upper mold 304 moves downward again to apply medium pressure to compress the tablet powder for the second time. At this time, the gaps between the powder particles are further reduced, and the density and strength of the tablet are increased. After the intermediate compression is completed, the upper mold 304 is slightly lifted again to relieve the pressure. The upper mold 304 moves downward for the last time, applies the maximum pressure, and completes the final compression of the tablet. At this time, the density and hardness of the tablet powder meet the requirements to form a final tablet.
[0033] Working principle: When compressing tablets, the fan 12 is started, and the tablet powder floating during compression is collected through the suction hood 15, and then the collected tablet powder is transported to the inside of the collection box 9 through the conveying pipe 14. The collection situation inside the collection box 9 can be observed through the transparent window 27. If it is full, the drawer 10 can be pulled out from the inside of the collection box 9 to recycle the collected tablet powder, so that it is convenient to collect the floating tablet powder when compressing the tablets. By collecting these powders, they can be reused to avoid waste and reduce production costs. Then, when it is necessary to replace a different lower mold 18, the handle 24 is pulled, and the handle 24 moves with the external fixed connecting rod 22, and the connecting rod 22 moves The slider 21 fixed externally moves laterally inside the mounting cavity 20, and when the slider 21 moves, the externally fixed insertion rod 25 moves, and at the same time, the spring 28 sleeved on the outside of the connecting rod 22 is squeezed. When the insertion rod 25 is separated from the inside of the socket 26, the mounting column 19 and the lower mold 18 can be taken out from the inside of the mounting block 17 for replacement. During installation, the new lower mold 18 and the mounting column 19 are inserted into the inside of the mounting block 17, and the handle 24 is released. The insertion rod 25 is inserted into the inside of the socket 26 under the reaction force of the spring 28. This makes it easy to replace different lower molds 18 in the tablet compression equipment, so that the equipment can adapt to the production of tablets of different specifications and shapes, meet diverse market demands, and improve the applicability of the equipment.
