Description

Technical Field

[0001] This utility model relates to the field of drug preparation technology, and in particular to a tablet press for drug preparation. Background Technology

[0002] Tablet presses are primarily used in pharmaceutical industry research on tablet manufacturing processes. A tablet press is an automated, continuous production line that compresses granular materials into round, irregularly shaped, or tablet-like objects with text, symbols, or graphics, with a diameter not exceeding 13mm. Some pharmaceutical tablet presses produce rough edges and dust during tablet compression; therefore, a sieve machine should be used in conjunction with the press for dust removal. GMP (Good Manufacturing Practice) standards must be met.

[0003] A search revealed a tablet compressor for drug preparation, disclosed in publication (announcement) number CN216373457U. The tablet compressor includes a body, a brake motor at the lower end of the body, brackets fixedly connected to the four corners of the lower end of the brake motor, a storage box at the upper end of the body, a closing plate movably connected to the upper end of the storage box, a discharge pipe fixedly connected to the center of one side of the body, a button at the center of one side of the brake motor, a feeding plate inside the storage box, a guide pipe connected to the lower end of the feeding plate, an upper punch ring connected to the lower end of the guide pipe, the guide pipe passing through the upper punch ring, an impact pipe connected to the lower end of the guide pipe, an electric valve inside the impact pipe, an extractor on one side of the upper punch ring, an extraction pipe inside the extractor, the upper end of the extraction pipe connected to the inside of the storage box, a guide port at the lower end of the extractor, and a filter screen inside the lower end of the guide port. This tablet compressor for drug preparation, by incorporating an extractor, an ultraviolet lamp, and a retaining plate, achieves a cleaner discharge port and prevents pills from being contaminated with drug powder during use.

[0004] While the above solution achieves the goal of cleaner discharge port and prevents pills from being contaminated with powder by setting up an extractor, ultraviolet lamp, and buckle plate, it cannot prepare tablets of different sizes according to different drug dosages. Therefore, we propose a tablet compressor for drug preparation. Utility Model Content

[0005] The main purpose of this invention is to provide a tablet press for drug preparation, which solves the problem of not being able to prepare tablets of different sizes according to different drug dosages by setting up a model unit and a pressing unit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A tablet compressor for drug preparation includes a main body unit, a mold unit and a pressing unit disposed inside the main body unit, and a discharge unit disposed on the side of the main body unit, wherein the pressing unit is located above the mold unit. The model unit includes a middle mold ring installed on the inner side wall of the main unit, a drive motor installed on the inner bottom wall of the main unit, a preparation plate installed at the output end of the drive motor and located inside the middle mold ring, a support member set inside the main unit and located below the preparation plate, and an injection member set inside the main unit and located above the preparation plate, and the preparation plate has multiple rings of molding holes of different sizes. The pressing unit includes a hydraulic telescopic rod installed on the top wall inside the main unit, a connecting seat installed on the telescopic end of the hydraulic telescopic rod, an electric telescopic rod installed on the inner side wall of the connecting seat, and a pressing component disposed at the end of the electric telescopic rod.

[0007] Preferably, the main unit includes a chassis, support feet mounted at the bottom of the chassis, and storage components disposed above the chassis.

[0008] Preferably, the storage component includes a storage box mounted on the top of the chassis and extending into the chassis, a sealing cover opened on the top of the storage box, and a lifting handle mounted on the top of the sealing cover.

[0009] Preferably, the support includes a hydraulic cylinder installed on the bottom wall of the machine housing, a fixed plate installed on the telescopic end of the hydraulic cylinder, and a support seat installed on the top of the fixed plate and corresponding to the forming hole.

[0010] Preferably, the dispensing component includes a dispensing tube installed at the bottom of the storage box and above the molding hole, and an electric valve installed inside the dispensing tube.

[0011] Preferably, the pressing component includes a connecting plate installed at the telescopic end of the electric telescopic rod, and a pressure column installed at the bottom of the connecting plate.

[0012] Preferably, the discharge unit includes a storage box installed on the inner side wall of the chassis and communicating with the middle mold ring, an extraction component installed between the storage box and the storage box, and a discharge pipe opened on the side wall of the chassis and communicating with the storage box.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In this invention, through the configured model unit and pressing unit, when it is necessary to prepare tablets of corresponding sizes according to the dosage of the drug, firstly, the extension end of the hydraulic cylinder extends, causing the fixed plate to move the support seat upward, sealing the bottom of the forming hole. The electric valve on the corresponding sized forming hole then opens, allowing the powder in the storage box to be injected into the forming hole through the injection tube. Subsequently, the extension end of the electric telescopic rod extends, positioning the pressing component directly above the forming hole. Then, the extension end of the hydraulic telescopic rod extends, causing the connecting plate to move the pressure column downward, thereby pressing the tablets through the pressure column and... The support base compresses the drug powder into tablets, thus enabling the preparation of tablets of the corresponding size according to the dosage of the drug. When it is necessary to discharge the tablets, the pressure column moves out of the forming hole, and the extension end of the hydraulic cylinder continues to extend. The tablets in the forming hole are pushed out by the support base and stop when they are above the preparation plate. The drive motor drives the preparation plate to rotate, and through the action of centrifugal force, the tablets are thrown from the middle mold ring into the storage box. Then, the extraction component works to suck up the drug powder on the tablets. After the tablets accumulate to a certain weight, they will be discharged from the storage box through the discharge pipe. Attached Figure Description
