Description

Technical Field

[0001] The invention relates to tablet pressing technology, in particular to a tablet pressing machine for pharmaceutical tablets. Background Art

[0002] A tablet press is a device used to make tablets. It uses pressure to press raw drug powder or granules into tablets of fixed shape and size. This type of equipment is commonly used in the pharmaceutical industry to improve the efficiency and quality of drug production and can produce tablets of different specifications and shapes.

[0003] The Chinese invention patent with publication number CN118893857B discloses a pharmaceutical tablet press, wherein a positioning spring drives a positioning slide column via a positioning slide plate to maintain engagement with a linkage chute and linkage longitudinal slot. Since the linkage chute and linkage longitudinal slot are interconnected, when the upper die moves downward, the rotary table remains stationary, facilitating the upper and lower dies to cooperate in pre-pressing, tableting, and unloading operations. When the upper die moves upward, the rotary table first remains stationary and then rotates, thereby rotating the tableting chamber to perform the next step, improving operational continuity and production efficiency. Turning the adjustment lever can drive the limit rod to separate from the limit slot, thereby rotating the adjustment plate. Since the adjustment plate and the adjustment stud are threadedly engaged, and the fixed slot and the fixed block are slidably engaged, the height of the tableting sleeve can be adjusted by rotating the adjustment plate, thereby adjusting the height of the tableting rod, thereby adjusting the tablet compression pressure according to tablet production needs, expanding the scope of application and improving ease of use.

[0004] When existing equipment is used, due to the uneven distribution of powder or particles in the mold, some areas may be subjected to excessive pressure or insufficient pressing, which may cause cracks; at the same time, the materials are all in powder form, which leads to the internal agglomeration phenomenon when piled together, resulting in poor overall fluidity, and the material is prone to uneven distribution during the filling process.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention. The terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. In addition, unless otherwise expressly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, they can be fixedly connected, detachably connected, or integrally connected; they can be mechanically connected or electrically connected; they can be directly connected or indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example: See Figures 1-9 A pharmaceutical tablet press comprises a base 1, an end of the base 1 is fixedly mounted with a support column 11, and one side of the support column 11 is fixedly mounted with a transmission member 12.

[0024] In this solution, a guide rail is provided at the end of the base 1, which limits the pressing cylinder 13 so that after the pressing cylinder 13 is filled with material, it is transferred to the lower end of the pressing component to compact the material.

[0025] The transmission member 12 is a device with power output, such as a motor, and is connected to an external control device. When the transmission member 12 is started, it rotates in conjunction with the gear fixedly installed at its end.

[0026] Furthermore, the orienting component 2 is assembled on one side of the support column 11, and the balance adjustment of the conveyed material is performed through the orienting component 2; wherein, the orienting component 2 includes a positioning plate 23 that is interlocked and connected to the support column 11, and the end of the positioning plate 23 is rotatably mounted with a rotating drum 21, and the end of the rotating drum 21 is fixedly mounted with a transmission ring 22, and the end of the transmission ring 22 is in contact with the end of the transmission member 12.

[0027] In this embodiment, grooves corresponding to the gears are evenly formed at the ends of the transmission ring 22, and the inner walls of the grooves mesh with the outer surfaces of the gears, so that when the transmission member 12 is started, the transmission ring 22 is driven to rotate in conjunction with the gears.

[0028] Since the end of the transmission ring 22 is fixedly connected to the end of the drum 21 , and the end of the drum 21 is rotatably connected to the end of the positioning plate 23 , the entire drum 21 rotates.

[0029] Furthermore, a locking ring 231 is fixedly installed on one side of the positioning plate 23, a movable rod 24 is slidably installed on the inner wall of the locking ring 231, a clamping block 25 is rotatably installed on the end of the movable rod 24, and a guide groove 211 is provided on the outer surface of the rotating drum 21, and the outer surface of the end of the clamping block 25 is slidably connected to the inner wall of the guide groove 211.

[0030] Specifically, when the drum 21 rotates, the guide groove 211 provided on its outer surface is synchronously driven to rotate. Since the inner wall of the guide groove 211 is slidingly connected to the outer surface of the end of the clamping block 25, the guide groove 211 is convex in the expanded state, so that when the drum 21 rotates, the clamping block 25 is driven to telescopically move along the inner wall of the locking ring 231.

[0031] Furthermore, an adjustment plate 28 is fixedly mounted on the end of the movable rod 24 , and a pressing cylinder 13 is slidably mounted on the end of the base 1 , and the inner wall of the pressing cylinder 13 is slidably connected to the outer surface of the adjustment plate 28 .

[0032] Specifically, when the movable rod 24 moves, the adjustment plate 28 fixedly installed at its end is simultaneously driven to move, and the material accumulated inside the pressing cylinder 13 is pushed flatly through the adjustment plate 28, so as to avoid the generation of cracks during subsequent pressing.

[0033] The lower end of the adjustment plate 28 is provided with a plurality of cleaning rods and cleaning grooves. The material is evenly distributed inside the pressing cylinder 13 through the squeezing and rotation of the adjustment plate 28 .

[0034] Furthermore, an adjustment slot 232 is formed at the end of the positioning plate 23 , a swing block 27 is slidably mounted on the inner wall of the adjustment slot 232 , and a rotating plate 26 is rotatably mounted on the end of the swing block 27 .

[0035] Specifically, a transmission plate is rotatably provided at the lower end of the positioning plate 23, and an adjustment groove 232 is provided on the transmission plate, wherein a transmission rod is rotatably installed at the end of the positioning plate 23, and tooth grooves are provided on the outer surfaces of the rotating drum 21 and the transmission plate, and the two ends of the transmission rod are respectively embedded in the tooth grooves on the rotating drum 21 and the transmission plate.

[0036] Therefore, when the rotating drum 21 rotates, the transmission rod synchronously drives the transmission plate to rotate, and synchronously drives the adjustment slot 232 to rotate.

[0037] The end of the swing block 27 is slidably connected to the inner wall of the adjustment groove 232 . The cross section of the adjustment groove 232 is elliptical, so that the swing block 27 is driven to move when the adjustment groove 232 rotates.

[0038] Furthermore, a clamping groove 261 is defined at the end of the rotating plate 26 , and a movable groove 241 is defined on the outer surface of the movable rod 24 . The outer surface of the movable rod 24 is slidably connected to the inner wall of the clamping groove 261 .

[0039] Specifically, since the engaging groove 261 on the rotating plate 26 is engaged with the movable groove 241 on the movable rod 24 , the movable rod 24 can only telescopically move along the inner wall of the engaging groove 261 .

[0040] At the same time, when the swing block 27 is subjected to force, the rotating plate 26 rotatably mounted on the end thereof is driven to move, thereby driving the movable rod 24 to rotate around the inner wall of the locking ring 231 .

[0041] Furthermore, the end of the positioning plate 23 is connected to a transmission tube 29 , and the end of the transmission tube 29 passes through and extends to the inner cavity of the positioning plate 23 .

[0042] Specifically, the inner wall of the transmission pipe 29 is made of a smooth material, and the cross section of the transmission pipe 29 is arc-shaped, which facilitates the transmission of materials.

[0043] Furthermore, the flow component 3 is assembled in the inner cavity of the directional component 2, and cooperates with the directional component 2 to uniformly transport the material; the flow component 3 includes a support plate 33 that is clamped with the end of the positioning plate 23, and a protective tube 312 is fixedly installed on the outer surface of the support plate 33, and a fixed plate 31 is rotatably installed on the end of the protective tube 312, and an annular groove 311 is opened at the end of the fixed plate 31.

[0044] In this embodiment, the support plate 33 and the positioning plate 23 are supported by a support rod. At the same time, a locking rod is clamped at the end of the fixed plate 31, and the end of the locking rod extends to the outside of the rotating drum 21 and is connected to the end of the support column 11, thereby keeping the flow component 3 stably in the inner cavity of the rotating drum 21.

[0045] Furthermore, a driving member 32 is fixedly installed at a middle position of the end of the supporting plate 33 , and an output end of the driving member 32 is fixedly connected to the end of the fixing plate 31 .

[0046] Specifically, the driver 32 activates a device with a power output, such as a motor, and is connected to an external control device. When the driver 32 is activated, it simultaneously drives the fixed plate 31 fixed to its output end to rotate. The rotation of the fixed plate 31 also drives the annular groove 311 defined at its end to rotate. The inner wall of the annular groove 311 is provided with multiple sets of teeth.

[0047] Furthermore, a plurality of locking blocks 381 are evenly and fixedly mounted on the inner wall of the protective tube 312 , a transmission rod 38 is rotatably mounted on the inner wall of the locking block 381 , and a push rod 39 is rotatably mounted on the end of the transmission rod 38 .

[0048] Specifically, a gear corresponding to the tooth block is provided at the end of the transmission rod 38, and the transmission rod 38 is driven to rotate around the inner wall of the locking block 381 by rotating the fixed plate 31 to cooperate with the tooth block, wherein the cross-section of the transmission rod 38 is Z-shaped, so that when the transmission rod 38 rotates, the push rod 39 is driven to move.

[0049] Furthermore, a driving plate 34 corresponding to the locking block 381 is rotatably mounted on the end of the support plate 33 , and a driving groove 341 is opened at the end of the driving plate 34 , and the inner wall of the driving groove 341 is slidably connected to the outer surface of the end of the push rod 39 .

[0050] Specifically, since the outer surface of the end of the push rod 39 is slidably connected to the inner wall of the driving groove 341, the driving plate 34 is driven to rotate around the connection with the supporting plate 33 when the push rod 39 moves.

[0051] Furthermore, an arc-shaped tooth block 35 is fixedly mounted on the outer surface of the driving plate 34 , and a positioning block 36 is fixedly mounted on the end of the support plate 33 . A transmission gear 361 is rotatably mounted on the end of the positioning block 36 , and the outer surface of the transmission gear 361 is meshed with the outer surface of the arc-shaped tooth block 35 .

[0052] Specifically, when the driving plate 34 rotates, the arc-shaped tooth block 35 fixedly mounted on its end is synchronously driven to move. Since the outer surface of the transmission gear 361 meshes with the outer surface of the arc-shaped tooth block 35, the transmission gear 361 rotates.

[0053] Furthermore, the end of the transmission gear 361 passes through and extends to the outside of the support plate 33, and the end of the transmission gear 361 is fixedly installed with a power rod 37, and the end of the power rod 37 is fixedly installed with a power plate 371, and the end of the power plate 371 is clamped with a limiting block 372, and the end of the limiting block 372 is fixedly installed with an elastic member 373, and the end of the elastic member 373 is fixedly installed with a conical block 374.

[0054] Specifically, when the transmission gear 361 rotates, it synchronously drives the power rod 37 fixedly installed at its end to move, and the power plate 371 is fixedly installed at one end away from the transmission gear 361, so that when the power plate 371 is subjected to force, it rotates around the transmission gear 361 and pushes the material at the end of the transmission pipe 29.

[0055] The elastic member 373 is an elastic component such as a spring, which cooperates with the conical block 374 fixedly installed at its end to push the material. At the same time, when the conical block 374 moves from the end of the positioning plate 23 to the inner wall of the transmission tube 29, the elastic member 373 causes the conical block 374 to contact the inner wall of the transmission tube 29, thereby generating vibration, which disperses the docking material and reduces material accumulation.

[0056] By adjusting the speed and vibration frequency of the flow component 3, the flow rate of the powder can be precisely controlled to ensure a consistent amount of powder for each tableting, thereby preventing inconsistent tablet hardness and weight due to excessive or insufficient powder.

[0057] The control device can use a single-chip microcomputer as the control terminal. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (MCU), consisting of an arithmetic unit, a controller, memory, and input / output devices, equivalent to a miniature computer. Compared to the general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its greatest advantages are its small size, allowing it to be placed inside the instrument, low memory capacity, simple input / output interfaces, and low functional consumption.

[0058] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
