[0002] In the process of developing new drugs, it is necessary to continuously analyze the properties of drugs with various formulations and conduct quantitative analysis on drugs with the same formulation in order to obtain the optimal formulation and optimal dosage. During the analysis process, a small amount of powdered drug needs to be compressed into tablets or pills for feeding experimental animals. Small pressing devices are commonly used for manual compression.

[0003] For example, the pressing device for drug production with Chinese patent number CN222039714U uses a pressure plate to compress drugs into tablets and a cleaning device to clean the surface of the tableting device. However, this device requires cleaning after each tableting operation before it can be used again, which reduces the efficiency of drug tableting and is inconvenient to use. Therefore, a pressing device for drug production is proposed to solve the above-mentioned problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A pressing device for drug production includes a receiving box 1, a conveyor 2 installed inside the receiving box 1, a drawer box 3 movably installed inside the receiving box 1, and a tablet pressing mechanism 4 provided inside the receiving box 1.

[0022] The tablet pressing mechanism 4 includes a placement box 401, which is fixedly installed on the outside of the conveyor 2. A first electric push rod 402 is installed inside the placement box 401. An ejector plate 403 is installed on the top of the first electric push rod 402. An electric slide 404 is installed on the inner rear wall of the receiving box 1. A horizontal plate 405 is installed on the front side of the electric slide 404. A measuring cylinder 406 is installed at the bottom of the horizontal plate 405. A second electric push rod 407 is installed inside the horizontal plate 405. A cylinder 408 is installed on the outside of the receiving box 1. A limit plate 409 is provided at the bottom of the cylinder 408. A pressure plate 410 is provided inside the receiving box 1.

[0023] exist Figure 1 and Figure 2 In the middle, a storage box 5 is fixedly installed on the rear side of the receiving box 1, and a guide pipe 6 is connected to the outside of the storage box 5.

[0024] Specifically, the controller drives the booster pump to start, at which point the powder enters each metering cylinder 406 through five feed pipes 6, thereby achieving the purpose of automatic feeding.

[0025] exist Figure 1 and Figure 2 In this context, the feed pipe 6 is a corrugated hose, and the side of the feed pipe 6 away from the storage tank 5 is connected to the rear side of the metering cylinder 406.

[0026] Specifically, through the coordinated operation of the various structures of the tableting mechanism 4, the powdered drugs can be quickly compressed and ejected into tablets without the need for manual cleaning, making it very convenient to use. Furthermore, the metering device ensures that each tablet has the same quality, thus resulting in better quality of the finished product.

[0027] exist Figure 1 and Figure 3 There are two sets of placement boxes 401, with five placement boxes 401 in each set. The two sets of placement boxes 401 are located at the top and bottom of the conveyor 2, respectively.

[0028] Specifically, the powder is added to the placement box 401. At this time, the controller drives the cylinder 408 to start, which moves the limit plate 409 and the bottom pressure plate 410 downward. The pressure plate enters the placement box 401, thereby achieving the purpose of tableting the medicine.

[0029] exist Figure 2 and Figure 3 In the middle, there are two electric slide tables 404, and both electric slide tables 404 are slidably connected to the horizontal plate 405.

[0030] Specifically, the controller drives the electric slide 404 to start, which in turn drives the measuring cylinder 406 to rise and fall.

[0031] exist Figure 2 and Figure 3 In the middle, the second electric push rod 407 extends into the interior of the metering cylinder 406 from the side away from the horizontal plate 405. A piston is connected to the bottom of the second electric push rod 407, and five extension rods are installed at the bottom of the limiting plate 409.

[0032] exist Figure 2 and Figure 4 In the middle, five extension rods are connected to five pressure plates 410 respectively, and the five pressure plates 410 correspond to the positions of five placement boxes 401 respectively.

[0033] In summary, the pressing device for drug production, by setting a first electric push rod 402, is driven by the controller to move the ejector plate 403 upward, ejecting the tablets from the placement box 401, preventing the medicine from sticking in the placement box 401 and making it inconvenient to use. By setting an electric slide table 404, when it is necessary to add medicine powder, the controller drives the electric slide table 404 to start, moving the measuring cylinder 406 close to the placement box 401. At this time, the controller drives the second electric push rod 407 to drive the piston to add the medicine powder into the placement box 401, thereby preventing the medicine powder from floating.

[0034] Furthermore, during use, when tableting is required, the controller drives the booster pump to start. At this time, the powder enters each metering cylinder 406 through five feed pipes 6. When the metering cylinder 406 is full, the controller drives the electric slide 404 to start, which moves the metering cylinder 406 close to the placement box 401. At this time, the controller drives the second electric push rod 407 to drive the piston to add the powder into the placement box 401. After the feeding is completed, the controller drives the electric slide 404 to move the metering cylinder 406 upward. At this time, the controller drives the cylinder 408 to start, which moves the limit plate 409 and the bottom pressure plate 410 downward. The pressure plate 410 enters the placement box 401, which makes the powder quickly form tablets. Finally, the controller drives the conveyor 2 to start, which moves the top receiving box 401 to the top of the drawer box 3. At this time, the controller drives the first electric push rod 402 to move the ejector plate 403 to eject the tablets out of the placement box 401. The tablets then enter the drawer box 3 for temporary storage.
