Description

Technical Field

[0001] This utility model belongs to the field of tablet preparation technology, specifically relating to a tablet compression device. Background Technology

[0002] In the pharmaceutical industry, tablets are the most widely used solid dosage form. Their production process mainly includes multiple stages such as granulation, drying, sizing, mixing, tableting, coating, and packaging. Among these, tableting is a key process that directly affects the physical properties and quality stability of the tablets. The tableting unit, as the core equipment for tablet forming, has a structural design and a degree of automation that directly determines the tablet pressing efficiency, quality consistency, and the cleanliness and continuity of the production process.

[0003] Existing tableting equipment typically lacks an effective mechanism for detecting and cleaning residual tablets in the compression chamber after tableting. This can easily lead to cross-contamination or mold damage during subsequent tablet compression processes, affecting tablet quality and equipment lifespan. Therefore, there is an urgent need for a tablet compression device with a reasonable structure, high degree of automation, efficient loading, precise compression, automatic detection and cleaning, and automatic tablet collection capabilities to meet the modern pharmaceutical industry's production demands for high efficiency, high quality, and high cleanliness.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0005] To solve the technical problems existing in the prior art, this utility model provides a tablet compression device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tablet compression apparatus includes a rotating table with a plurality of tableting stations, each tableting station including two parallel tableting slots. Three tableting mechanisms are provided on one side of the rotating table, each tableting mechanism including a filling assembly and a tableting assembly.

[0008] The canning assembly includes a first frame, on which a hopper is provided, and at the bottom of the hopper a guide pipe is provided, the outlet end of which corresponds to the position of the tableting groove;

[0009] The tableting assembly includes a second frame, on which a first drive assembly is provided. A tableting component is provided at the bottom of the first drive assembly. The first drive assembly is used to drive the tableting component to move up and down in the vertical direction. The tableting component corresponds to the position of the tableting slot. A support plate is provided at the bottom of each of the two tableting slots. A second drive assembly and a rotating assembly are provided at the bottom of the support plate. The second drive assembly is used to drive the support plate to move up and down in the vertical direction of the tableting slot. The rotating assembly is used to tilt the support plate.

[0010] The second frame is provided with a collection frame and a third drive assembly on both sides. The third drive assembly is used to drive the collection frame to reciprocate in the horizontal direction and is used to cooperate with the support plate when tilting.

[0011] The second drive assembly includes a horizontal plate, on which two first telescopic motors are provided, and the support plate is disposed on the first telescopic rods of the two first telescopic motors.

[0012] The rotating assembly includes a base with a rotating rod on it, and a horizontal plate rotatably mounted on the rotating rod. A vertical plate is mounted on the horizontal plate and positioned between two first telescopic motors. A rotating plate is mounted on the top of the vertical plate. A second telescopic motor is positioned between two second drive assemblies. One end of the rotating plate is rotatably mounted on the top of the vertical plate, and the other end is rotatably mounted on the second telescopic rod of the second telescopic motor. The rotating assembly is used to drive the parallel support plates to tilt or straighten simultaneously.

[0013] The bottom of the rotating platform is equipped with several support and guiding mechanisms.

[0014] The support and guiding mechanism includes a third frame, the top of which is provided with rollers, which are in contact with the bottom of the rotating platform.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) This application provides a tablet compression device, which realizes continuous and automated tablet compression operation by setting a rotating table and multiple parallel tablet compression slots, in conjunction with a filling component and a tablet compression component. Specifically, the hopper and guide pipe in the filling component can uniformly introduce the powder or granules into the tablet compression slot. The tablet compression component in the tablet compression component compresses the tablets under the drive of the first drive component. The structure is compact and the operation is stable. Then, through the cooperation of the support plate with the second drive component and the rotating component, the support plate can move up and down and realize the tilting action after the tablet is compressed, so as to smoothly discharge the tablets in the tablet compression slot. The third drive component drives the collection frame to move horizontally back and forth, which, in conjunction with the tilting action of the support plate, realizes the intelligent collection of tablets and improves the automation level of the equipment.

[0030] The present invention will be further described below with reference to specific embodiments.

[0031] In the following description, all directional (or orientational) concepts involving up, down, left, right, front, and back refer to the position of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be construed as a special limitation on the technical solution provided by this utility model.

[0032] like Figures 1-7 As shown, a tablet compression device includes a rotating table 1 with several compression stations 2 on it. Each compression station 2 includes two parallel compression slots 21. Three compression mechanisms are provided on one side of the rotating table 1. Each compression mechanism includes a filling assembly and a compression assembly, which are used to complete operations such as filling, compression, and tablet discharge. The filling assembly includes a first frame 31 with a hopper 32 on it. A guide pipe 33 is provided at the bottom of the hopper 32. The outlet end of the guide pipe 33 corresponds to the position of the compression slot 21. A valve is provided on the guide pipe 33 to control the precise introduction of powder or granular material into the compression slot 21, achieving uniform filling.

[0033] The tableting assembly includes a second frame 41, on which a first drive assembly 42 is mounted. A tablet pressing component 43 is located at the bottom of the first drive assembly 42. The first drive assembly 42 drives the tablet pressing component 43 to move vertically up and down, pressing the material in the tableting groove 21 to form a tablet 12. (The first drive assembly 42 can be a cylinder, hydraulic cylinder, or servo motor drive structure, capable of precise control of the pressing force, thereby ensuring the consistency of the tablet 12's hardness and quality.) The tablet pressing component 43 corresponds to the position of the tableting groove 21. Support plates 51 are provided at the bottom of both tableting grooves 21. The bottom of the support plate 51 is provided with a second drive assembly and a rotating assembly. The second drive assembly is used to drive the support plate 51 to move up and down in the vertical direction of the tablet pressing groove 21. The rotating assembly is used to drive the support plate 51 to tilt, so that the tablets 12 can be smoothly discharged under the action of gravity, avoiding residue or jamming. The second frame 41 is provided with a collection frame 61 and a third drive assembly 62 on both sides (the third drive assembly 62 can be a telescopic motor or a cylinder). The third drive assembly 62 is used to drive the collection frame 61 to reciprocate in the horizontal direction, and is used to cooperate with the support plate 51 when tilting, that is, when the support plate 51 is tilted, the tablets 12 fall into the collection frame 61.

[0034] The second drive assembly includes a horizontal plate 52, on which two first telescopic motors 53 are mounted, and a support plate 51 is mounted on the first telescopic rods of the two first telescopic motors 53. The rotating assembly includes a base 71, on which a rotating rod 72 is mounted, and the horizontal plate 52 is rotatably mounted on the rotating rod 72; a vertical plate 73 is mounted on the horizontal plate 52, and the vertical plate 73 is positioned between the two first telescopic motors 53, with a rotating plate 74 mounted on top of the vertical plate 73; a second telescopic motor 75 is positioned between the two second drive assemblies, with one end of the rotating plate 74 rotatably mounted on the top of the vertical plate 73, and the other end rotatably mounted on the second telescopic rod of the second telescopic motor 75; the rotating assembly is used to drive the parallel support plates 51 to tilt or straighten simultaneously.

[0035] The bottom of the rotating platform 1 is provided with several support and guide mechanisms, including a third frame 81. The top of the third frame 81 is provided with rollers 82, which are in contact with the bottom of the rotating platform 1.

[0036] A cleaning mechanism and a detection mechanism are also provided on one side of the rotating table 1. The cleaning mechanism includes a fourth frame 90, on which a jet nozzle 91 and an air inlet pipe 92 connected to the jet nozzle 91 are provided. The jet nozzle 91 is configured to cooperate with the tablet compression chamber 21 for efficient cleaning of the tablet compression chamber 21 after the tablets 12 are discharged. The detection mechanism includes a fifth frame 10, on which a sensor 11 is provided for real-time detection of whether there are residual tablets 12 or abnormal compression in the tablet compression chamber 21, thereby improving the safety and intelligence level of the equipment operation.

[0037] Specifically, the rotating table 1 starts to rotate, with the tableting mechanism closest to the testing mechanism as the first working position. The material is introduced into the tableting groove 21 through the guide pipe 33. When the tableting table 2 rotates to the position of the second frame 41, the first drive assembly 42 is driven, and the tableting component 43 is used to press and prepare the material in the tableting groove 21. At the same time as the tableting component 43 finishes working, the second drive assembly drives the support plate 51 to move downward in the vertical direction of the tableting groove 21. The rotating assembly is used to drive the support plate 51 to tilt, so that the tablet 12 can be smoothly discharged under the action of gravity. At the same time as the support plate 51 tilts, the third drive assembly 62 drives the collection frame 61 to move towards the tableting table 2, so that when the support plate 51 tilts, the tablet 12 falls into the collection frame 61. After the tablet 12 falls into the collection frame 61, the collection frame 61 immediately moves away from the tableting table 2 to prevent collision when the rotating table 1 drives the tableting table 2 to rotate. After tableting at the three stations, the tableting table 2 rotates to the cleaning mechanism to clean the tableting tank 21 with air jets, and then rotates to the inspection mechanism to check whether there are residual tablets 12 or abnormalities in the tableting tank 21.

[0038] This application provides a tablet compression device. By setting a rotating table 1 and multiple parallel compression slots 21, in conjunction with a filling assembly and a compression assembly, continuous and automated tablet compression operation is achieved. Specifically, the hopper 32 and the guide pipe 33 in the filling assembly can uniformly introduce the powder or granules into the compression slots 21. The compression component 43 in the compression assembly, driven by the first drive assembly 42, compresses the tablets 12. The structure is compact and the operation is stable. Furthermore, the support plate 51, in conjunction with the second drive assembly and the rotating assembly, allows the support plate 51 to move up and down and tilt after compression, thereby smoothly discharging the tablets 12 from the compression slots 21. The third drive assembly 62 drives the collection frame 61 to reciprocate horizontally, which, in conjunction with the tilting action of the support plate 51, realizes intelligent collection of the tablets 12 and improves the automation level of the equipment.

[0039] This application also includes a cleaning mechanism and a detection mechanism. The jet nozzle 91 can efficiently clean the tablet compression chamber 21 to prevent residue from contaminating the next batch of tablets 12. The sensor 11 can detect in real time whether there are any tablets 12 remaining in the tablet compression chamber 21, thereby improving the safety and stability of the equipment operation. The support and guidance mechanism effectively improves the smoothness of the turntable 1 operation and extends the service life of the equipment.

[0040] In summary, this application has a reasonable structural design and high functional integration, and has the advantages of high automation, high tableting efficiency, strong cleaning ability, accurate detection, and convenient collection. It is suitable for the high standard requirements of tablet production in modern pharmaceutical industry.
