Description

Technical Field

[0001] This utility model relates to the field of tablet pharmaceutical processing technology, and in particular to a high-efficiency tablet press for tablet pharmaceutical processing. Background Technology

[0002] Tablets are solid dosage forms produced by compressing a mixture of active pharmaceutical ingredients and excipients. They offer advantages such as precise dosage, high stability, and ease of carrying and administration, making them one of the most widely used formulations in the pharmaceutical industry. Tableting, as the core step in tablet production, is crucial in using a tableting machine to compress the mixture into tablets that meet quality standards. This process not only imparts specific shape, hardness, and disintegration properties to the drug but also enables precise drug delivery through coating, sustained-release, and other technologies.

[0003] However, existing tablet presses still have the following technical problems in practical applications:

[0004] 1) Tablet sticking or jamming during discharge: There is a type of tablet press that relies on adsorption to pick up the material. The suction head picks up the material by adsorbing the material with a suction fan, which can easily cause the tablets to stick to the tableting chamber. The suction fan has pressure fluctuations, which can easily lead to material picking failure. In addition, the accumulation of tablets can easily block the discharge pipe.

[0005] 2) Lack of dust control: During the tableting process, material friction causes dust to splash, which can easily lead to equipment failure or tablet contamination. In addition, the tableting block and the placement slot are connected by bolts, resulting in many dead corners for cleaning.

[0006] Therefore, there is an urgent need to develop a high-efficiency tablet press for tablet drug processing in order to solve the problems mentioned above. Utility Model Content

However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Please see Figure 1 , Figure 6 and Figure 7 A high-efficiency tablet press for tablet pharmaceutical processing includes a housing 1 and a partition 2. The partition 2 is horizontally positioned inside the housing 1, dividing it into upper and lower cavities. A material-carrying turntable assembly 3 is rotatably mounted in the middle of the partition 2.

A transparent sealing cover 7 is provided on the upper front side of the housing 1. A receiving box 8 and a servo motor 9 are installed inside the housing 1 below the partition 2. The material-carrying turntable assembly 3 includes a rotatable connection... The turntable 31 at the top of the partition 2 has several circumferentially evenly distributed placement slots. A second magnetic block 37 is fixedly installed at the bottom of each placement slot. A pressing block 32 is placed in the placement slot. A first magnetic block 36 that magnetically attracts and cooperates with the second magnetic block 37 is fixedly installed at the bottom of the pressing block 32. A pressing groove 33 is opened inside the pressing block 32. A small hydraulic pump 34 is fixedly installed at the bottom of the pressing groove 33. A top block 35 that slides and cooperates with the pressing groove 33 is fixedly connected to the output end of the small hydraulic pump 34.

[0029] It should be specifically noted that the output shaft of the servo motor 9 passes through the partition 2 and is fixedly connected to the center position of the turntable 31. The servo motor 9 is used to drive the turntable 31 to rotate at a constant speed.

[0030] Furthermore, the tableting block 32 is designed as a detachable and replaceable modular structure. To meet the needs of different drug dosage forms, the inner wall contour of the tableting groove 33 is available in various models, including but not limited to round, oval, and irregular shapes, to meet the appearance design requirements of different tablets. The shape of the tableting head is precisely matched with the tableting groove of the corresponding tableting block.

[0031] Furthermore, there are several tableting blocks 32, which are distributed equidistantly around the center of the turntable 31; the edge of the tableting groove 33 is provided with a 45° guide slope to guide the material to be evenly distributed and avoid accumulation.

[0032] Furthermore, the outer surface of the top block 35 is in close contact with the inner wall of the tableting groove 33 to avoid material residue. The tableting groove 33, the top block 35 and other material contact parts are made of 316L stainless steel with mirror polishing to achieve quick mold change and cleaning.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The material handling component 4 includes a positioning post 42 fixed to the top of the box 1 by a first fixing plate 41. An L-shaped dust cover 44 is fixedly installed at the bottom of the positioning post 42 by a second fixing plate 43. The tail end of the L-shaped dust cover 44 is integrally formed with a material handling port 45. Several fixing posts 46 are fixedly provided at the top inside the L-shaped dust cover 44. An arc-shaped guide block 47 is fixedly connected to the lower end of each fixing post 46.

[0034] It should be specifically noted that the front end of the L-shaped dust cover 44 is located directly above the tableting block 32, and the rear end extends to the outer edge of the turntable 31; the inner arc surface of the arc-shaped guide block 47 is adapted to the outer contour of the tableting groove 33, and the minimum installation height of the L-shaped dust cover 44 and the arc-shaped guide block 47 is 0.1-0.3mm higher than the upper surface of the turntable 31; the lower end of the feeding port 45 passes through the partition 2 and is connected to the receiving box 8.

[0035] Furthermore, the L-shaped dust cover 44 maintains a gap of 0.1-0.3mm with the upper surface of the turntable 31, which not only prevents dust from overflowing but also avoids interference with the turntable. The arc-shaped guide block 47 is adapted to the outer periphery of the tableting groove 33, guiding the tablets to fall accurately into the feeding port and preventing jamming and blockage.

[0036] Please see Figure 1 Figure 4 The tablet compression assembly 5 includes a fixed seat 52 fixed to the top of the box 1 by a third fixed plate 51. A cylinder 53 is fixedly installed in the middle of the lower end of the fixed seat 52. The movable end of the cylinder 53 is connected to the tablet compression head through a flange 55. A retractable dustproof conduit 56 is sleeved on the outside of the tablet compression head. Infrared sensors 54 are installed at the bottom of both sides of the fixed seat 52. The infrared sensors 54 are used to detect the position of the tablet compression block 32.

[0037] It should be specifically noted that the shape of the tablet press head is adapted to the tablet press groove 33, and the central axis of the tablet press head coincides with the central axis of the tablet press groove 33. The upper end of the dustproof conduit 56 is fixedly connected to the flange 55, and the lower end of the dustproof conduit 56 moves synchronously with the tablet press head to isolate the dust generated during the tablet pressing process and avoid contaminating the cylinder components.

[0038] Furthermore, the transparent sealing cover 7 seals the upper part of the box 1, and together with the L-shaped dust cover 44 and the dust duct 56, forms a semi-enclosed tableting space, reducing dust overflow by more than 90%.

[0039] Please see Figure 1 and Figure 5 The discharge assembly 6 includes a bucket-shaped discharge port 61 installed at the top of the box 1. The lower end of the bucket-shaped discharge port 61 passes through the box 1 and is connected to a material box 62. The front end of the material box 62 is provided with a viewing window 63. The lower end of the material box 62 is connected to a filling pipe 65 through a compression pump 64. The discharge end of the filling pipe 65 is located directly above the tableting groove 33.

[0040] Please see Figures 1-7 The working principle of the entire equipment in specific use is as follows: Step 1, initial preparation stage: The tableting block 32 is magnetically attracted to the second magnetic block 37 at the bottom of the rotating disk 31 by the first magnetic block 36 at the bottom. It can be quickly positioned and installed without bolts, ensuring that the tableting block 32 and the rotating disk 31 rotate synchronously, and the central axis of the tableting groove 33 is perpendicular to the rotating plane of the rotating disk 31. The material to be pressed is poured into the material box 62 of the discharge component 6 through the bucket-shaped discharge port 61. The operator observes the material inventory through the viewing window 63. The compression pump 64 is pre-adjusted to the set pressure and is ready to quantitatively fill the tableting groove 33 with material.

[0041] Step 2, Material Filling Process: When the tablet block 32 rotates with the turntable 31 to directly below the filling tube 65, the compression pump 64 starts and conveys the material in the material box 62 to the tableting groove 33 at a uniform speed through the filling tube 65. The 45° guide slope at the edge of the tableting groove 33 guides the material to be evenly distributed to avoid accumulation. The servo motor 9 drives the turntable 31 to rotate at a constant speed. After a single tablet block 32 is filled, the turntable continues to rotate to the next station.

[0042] Step 3, Tableting process: When the tableting block 32 rotates with the turntable 31 to below the tableting assembly 5, the infrared sensors 54 on both sides of the fixed base 52 detect the position of the tableting block 32, ensuring that the central axis of the tableting groove 33 is completely aligned with the central axis of the tableting head. The cylinder 53 drives the tableting head to move downward to press the material in the tableting groove 33 with the set pressure. The dustproof guide tube 56 extends and retracts synchronously with the tableting head to isolate the dust generated during the tableting process and avoid contaminating the cylinder components. The shape of the tableting head is completely adapted to the tableting groove 33. The pressing time is 0.5-2 seconds to ensure that the tablet hardness meets the pharmacopoeia standard. After the tableting is completed, the cylinder 53 drives the tableting head to reset, and the turntable 31 continues to rotate to the material picking station.

[0043] Step 4, Tablet Removal Process: When the tableting block 32 rotates to directly below the L-shaped dust cover 44, the small hydraulic pump 34 starts, pushing the top block 35 to slide upward along the inner wall of the tableting groove 33, pushing the compressed tablets out of the tableting groove 33. Under the rotational inertia of the turntable 31, the ejected tablets slide along the inner arc surface of the arc-shaped guide block 47 into the L-shaped dust cover 44, and fall into the receiving box 8 below the partition 2 through the feeding port 45. The L-shaped dust cover 44 maintains a gap of 0.1-0.3mm with the upper surface of the turntable 31, which not only prevents dust from overflowing, but also avoids interference with the turntable. The contour of the arc-shaped guide block 47 is adapted to the outer periphery of the tableting groove 33, guiding the tablets to fall accurately into the feeding port and preventing jamming.

[0044] Step 5, quick disassembly: The tablet block 32 comes in various models and is fixed by magnetic attraction. When replacing it, simply pull it upwards to remove it without tools.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
