[0002] Tablets are solid preparations in the form of flakes or special-shaped flakes that are formed by evenly mixing the drug and excipients and compressing them. Tablets are mainly ordinary tablets for oral administration, but there are also lozenges, sublingual tablets, oral patches, chewable tablets, dispersible tablets, effervescent tablets, vaginal tablets, rapid-release, sustained-release, controlled-release tablets, and enteric-coated tablets.

[0003] After searching, it is found that the tablet pressing device for tablet drug preparation in the prior art is typically such as a tablet pressing device for tablet drug production disclosed in the publication number CN216610197U, which includes a base plate and a receiving box, a mounting frame is welded and installed on the top of the base plate, and the mounting frame is arranged in an inverted "U" shape. An extrusion mechanism is arranged on the mounting frame, and a mounting groove is provided in the middle of the top of the base plate, just below the extrusion mechanism. Working plates are rotatably installed on the inner walls of both sides of the mounting groove. Tablet grooves are provided on the top and bottom of the working plate, and a motor is welded and installed on one side wall of the base plate. The tablet pressing device for tablet drug production, by setting a working plate with a flip structure, can be flipped when unloading is required, which improves the convenience of unloading.

[0004] In the prior art, tableting and tablet unloading are performed separately during the production of tablet medicines. Therefore, tableting of medicines cannot be performed during tablet unloading, which reduces production efficiency. Therefore, we propose a tableting device for preparing tablet medicines. Utility Model Content

[0005] The utility model aims to provide a tablet pressing device for preparing tablet medicines, which has the advantage of being able to continuously and synchronously complete the tablet pressing and unloading of medicines in a double-station manner, thereby greatly improving the production efficiency and solving the problem in the prior art that, during the production of tablet medicines, the tablet pressing and the unloading of the tablets are carried out separately, and the tablet pressing of the medicines cannot be carried out during the tablet unloading, thereby reducing the production efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tablet pressing device for preparing tablet medicines, comprising a material receiving box, a lifting plate and a rotating plate, a fixed frame is installed on the upper surface of the material receiving box, a rotating motor is installed at the middle position of the upper surface of the fixed frame, the end of the output shaft of the rotating motor is connected to the rotating plate, a plurality of extrusion holes are evenly arranged at both sides of the upper surface of the rotating plate, a discharge port is arranged on one side of the upper surface of the material receiving box, hydraulic cylinders are symmetrically installed at both sides of the upper surface of the fixed frame, and the ends of the output shafts of the two hydraulic cylinders are respectively connected to the positions on both sides of the upper surface of the lifting plate, and the lower surface of the lifting plate is connected to an extrusion rod at the position above each extrusion hole.

[0011] Preferably, a medicine powder discharge port is provided on the lower surface of the material receiving box.

[0012] Preferably, a baffle ring is installed on the upper surface of the material receiving box, and the rotating plate is located inside the baffle ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model achieves the effect of being able to continuously and synchronously complete the tableting and unloading of medicines in a double-station manner by arranging a material receiving box, a discharge port, a rotating plate, an extrusion hole, a rotating motor, a hydraulic cylinder, a lifting plate, a sleeve, a spring and an extrusion rod, thereby greatly improving the production efficiency. The hydraulic cylinder drives the lifting plate to descend, and the extrusion rod enters the extrusion hole and extrude the medicine powder in the hole to make it into a sheet. After the extrusion is completed, the rotating motor drives the rotating plate to rotate so that the tablets rotate to the position above the discharge port. During the descent of the lifting plate, the extrusion rod is inserted into the extrusion hole, and the elastic force of the spring causes the tablets in the extrusion hole to be pushed out and fall into the material receiving box from the discharge port, while the extrusion holes on both sides of the upper surface of the rotating plate synchronously complete the extrusion of medicines into tablets and the unloading of tablets, thereby greatly improving the production efficiency.

[0015] 2. The utility model achieves the effect of enabling the extrusion hole to be accurately rotated to the position directly below the extrusion rod when the rotating plate rotates by arranging a photoelectric transmitter and a photoelectric receiver. During the rotation of the rotating plate, when the photoelectric receiver moves to the position directly below the photoelectric transmitter, the photoelectric receiver receives the light signal emitted by the photoelectric transmitter, and the rotating motor stops working, so that the extrusion hole is rotated to the position directly below the extrusion rod, and the extrusion rod can be accurately inserted into the extrusion hole.

[0016] 3. The utility model achieves the effect of collecting the powder in production for recycling by means of the inclined filter screen, the powder discharge port and the tablet discharge port. When the tablet falls onto the inclined filter screen, the powder remaining on the tablet passes through the inclined filter screen and is discharged from the powder discharge port and collected, while the tablet is discharged from the tablet discharge port.
