Description

Technical Field

[0001] This utility model relates to the technical field of tablet presses, and more particularly to a pharmaceutical tablet press. Background Technology

[0002] Currently, tablet compressors are mainly used in pharmaceutical industry research on tablet manufacturing processes. In operation, the tablet compressor adds pharmaceutical powder into the lower mold through an inlet. The upper mold then moves downwards to merge the upper and lower molds, thus compressing the drug into tablets. After separating the upper and lower molds, the formed tablets need to be removed. However, existing mold-separation methods mostly rely on manual demolding. Because the compressed tablets are easily stuck in the groove of the lower mold, demolding becomes more difficult, increasing the workload. Furthermore, manual, forceful demolding can easily cause the tablets to break. Utility Model Content

[0003] To address the above shortcomings, this utility model proposes a pharmaceutical tablet press, which uses a rotating frame to rotate the placement plate downwards and uses an electromagnet to de-energize the elastic element to push the end plate downwards, thereby pushing the tablets out of the stepped holes to achieve rapid tablet demolding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A pharmaceutical tablet compressor includes: a frame, with a receiving box at the lower part of the frame; a pressure plate, movably mounted on the frame, connected to a first drive mechanism, with multiple pressure rods on the lower end face of the pressure plate; a tilting frame, rotatably mounted on the frame, connected to a second drive mechanism, with a fixed placement plate on the tilting frame, the placement plate having multiple stepped holes, the larger end of each stepped hole being rotatable to face upward toward the corresponding pressure rod; a movable plate movably mounted on the tilting frame, with an elastic element between the movable plate and the tilting frame; multiple end plates connected to one side of the movable plate, each end plate being retractably housed within the larger end of the stepped hole; a magnetic block on the other side of the movable plate; and an electromagnet cooperating with the magnetic block on the tilting frame. The electromagnet is connected to a power supply mechanism via a circuit. When the electromagnet is energized, the electromagnet and the magnetic block magnetically attract each other, causing the elastic element to be in a compressed state.

[0005] Furthermore, the flipping frame includes four mounting rods connected to the placement plate, the movable plate is provided with guide holes that cooperate with the mounting rods, one end of the mounting rod is provided with a limit plate, the electromagnet is provided on the limit plate, one end of the elastic element is connected to the movable plate, and the other end of the elastic element is connected to the limit plate.

[0006] Furthermore, one end of the mounting rod is provided with a threaded section, the threaded section is provided with two nuts, the limiting plate is provided with a through hole through which the mounting rod can move, and the limiting plate is clamped between the two nuts.

[0007] Furthermore, the elastic element is a spring that is movably sleeved on the mounting rod, and a washer is connected to the nut near the movable plate, and the spring is connected between the movable plate and the washer.

[0008] Furthermore, one end of the end plate is connected to a connecting rod, and one end of multiple connecting rods is connected to the movable plate.

[0009] Furthermore, side plates are provided on both sides of the placement plate, and each side plate is connected to a mounting shaft. The mounting shaft is rotatably mounted on the frame, and one of the mounting shafts is connected to the second drive mechanism.

[0010] Furthermore, the second drive mechanism is a motor mounted on the frame, and the output end of the motor is connected to one of the mounting shafts.

[0011] Furthermore, the first driving mechanism is a cylinder mounted on the frame, and the telescopic end of the cylinder is connected to the upper end face of the pressure plate.

[0012] Furthermore, the frame includes two opposing upright plates, a guide plate is inclinedly arranged between the two upright plates, and the receiving box is located below the guide plate.

[0013] Compared with existing technologies, this utility model has at least the following beneficial effects: 1. This utility model, through the energization of an electromagnet and the cooperation of a magnetic block, helps each end plate to remain in contact with the step surface of the corresponding stepped hole downwards, and with the downward movement of the pressure rod, it helps to compress the powder in the stepped hole into tablets.

[0014] 2. This utility model uses a flipping frame to flip the tablet so that the large end of the stepped hole faces downwards, and uses the electromagnet to lose its magnetism when de-energized, so that the elastic element resets and pushes the end plate downwards, thereby pushing the tablet out of the stepped hole to achieve rapid tablet demolding.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] See Figures 1 to 3A pharmaceutical tablet compressor includes: a frame 100, with a receiving box 110 at the lower part of the frame 100; a pressure plate 200, which is vertically mounted on the frame 100 and connected to a first drive mechanism, with multiple pressure rods 210 on the lower end face of the pressure plate 200; and a tilting frame, which is rotatably mounted on the frame 100 and connected to a second drive mechanism. The tilting frame is fixedly mounted with a placement plate 300, which has multiple stepped holes 301. The larger end of each stepped hole 301 can rotate upwards to face the corresponding pressure rod 210. The tilting frame is movable. A movable plate 310 is provided, and an elastic element 320 is provided between the movable plate 310 and the flipping frame. Multiple end plates 311 are connected to one side of the movable plate 310. Each end plate 311 is retractably built into the large port of the stepped hole 301. A magnetic block 312 is provided on the other side of the movable plate 310. An electromagnet 330 that cooperates with the magnetic block 312 is provided on the flipping frame. The electromagnet 330 is connected to a power supply mechanism 304 through a line. When the electromagnet 330 is energized, the electromagnet 330 and the magnetic block 312 attract each other magnetically so that the elastic element 320 is in a compressed state.

[0022] In the above-described pharmaceutical tablet press, when the electromagnet 330 is energized, the magnetic block 312 and the electromagnet 330 are magnetically attracted to each other, so that each end plate 311 abuts against the stepped surface of the corresponding stepped hole 301. Then, the pharmaceutical powder is first laid inside each stepped hole 301, and the first drive mechanism drives the pressure plate 200 to move downward, so that each pressure rod 210 presses down toward the corresponding stepped hole 301, thereby compressing the pharmaceutical powder into tablets. Then, the second drive mechanism drives the flipping frame to flip, so that the large end of the stepped hole 301 faces downward. Then, the power supply to the electromagnet 330 is disconnected, so that the electromagnet 330 loses its magnetism and the elastic element 320 restores its deformation, thereby driving the movable plate 310 to move downward. Finally, the tablets are released from the stepped holes 301 under the action of gravity and the downward pushing force of the end plate 311, and the tablets fall into the receiving box 110, thereby completing the rapid demolding of the tablets, which helps to reduce the difficulty of manual demolding.

[0023] It is understandable that multiple stepped holes 301 are distributed in a matrix on the placement plate 300, and each stepped hole 301 has a corresponding end plate 311 built into its large port. The end plate 311 and the peripheral wall of the stepped hole 301 enclose a cavity for placing the powder.

[0024] See Figures 1 to 3Furthermore, the tilting frame includes four mounting rods 340 connected to the placement plate 300. The movable plate 310 is provided with guide holes that cooperate with the mounting rods 340. A limit plate 350 is provided at one end of the mounting rod 340, and an electromagnet 330 is disposed on the limit plate 350. One end of the elastic element 320 is connected to the movable plate 310, and the other end of the elastic element 320 is connected to the limit plate 350. Specifically, the four mounting rods 340 facilitate the guiding and limiting of the movement of the movable plate 310, thereby facilitating the translation of the movable plate 310 relative to the mounting rods 340. The limit plate 350 provides a suitable position for the electromagnet 330. It can be understood that the multiple electromagnets 330 are connected in series, with a switch connected in series. The switch is electrically connected to the control panel, allowing users to easily turn the electromagnets 330 on and off via the control panel. The power supply mechanism 304 can be powered by a battery.

[0025] See Figures 1 to 3 Furthermore, one end of the mounting rod 340 is provided with a threaded section, and the threaded section has two nuts 341. The limiting plate 350 has a through hole through which the mounting rod 340 can move, and the limiting plate 350 is clamped between the two nuts 341. Specifically, by using the installation method of nuts 341, the installation position of the limiting plate 350 can be changed by adjusting the position of the nuts 341, thereby changing the deformation stroke of the elastic element 320.

[0026] See Figures 1 to 3 Furthermore, the elastic element 320 is a spring movably sleeved on the mounting rod 340. A washer 342 is connected to the nut 341 near the movable plate 310, and the spring is connected between the movable plate 310 and the washer 342. The arrangement of springs on each mounting rod 340 facilitates the return of the elastic element 320 to its original position through the compression of multiple springs. The washer 342 helps to regulate the deformation direction of the spring through planar contact. It is understood that the connections between the washer 342 and the nut 341, between the spring and the washer 342, and between the spring and the movable plate 310 are made by welding, which helps to improve the connection strength.

[0027] See Figures 1 to 3 Furthermore, one end of the end plate 311 is connected to a connecting rod 313, and one end of multiple connecting rods 313 is connected to the movable plate 310, thereby facilitating the movable plate 310 to drive the corresponding end plate 311 to move through multiple connecting rods 313.

[0028] See Figures 1 to 3Furthermore, side plates 302 are provided on both sides of the placement plate 300, and each side plate 302 is connected to a mounting shaft 303. The mounting shaft 303 is rotatably mounted on the frame 100, and one of the mounting shafts 303 is connected to the second drive mechanism, so that the tilting frame can be rotatably mounted on the frame 100 through the two mounting shafts 303, and thus the second drive mechanism can drive the tilting frame to rotate through one mounting shaft 303.

[0029] See Figures 1 to 2 Furthermore, the second drive mechanism is a motor 304 mounted on the frame 100. The output end of the motor 304 is connected to one of the mounting shafts 303, thereby driving the tilting frame to rotate. It can be understood that the frame 100 includes two opposing upright plates 101, each mounting shaft 303 is rotatably mounted on the corresponding upright plate 101, one of the upright plates 101 is provided with a horizontal plate, and the motor 304 is mounted on the horizontal plate.

[0030] See Figures 1 to 2 Furthermore, the first driving mechanism is a cylinder 120 mounted on the frame 100. The telescopic end of the cylinder 120 is connected to the upper surface of the pressure plate 200, thereby driving the pressure plate 200 to rise and fall vertically, which is beneficial for compressing the powder into tablets. It is understood that the frame 100 includes two opposing upright plates 101, with a flat plate connecting the upper ends of the two upright plates 101, and the cylinder is mounted on the flat plate. Alternatively, the cylinder 120 can be replaced with a hydraulic cylinder, which will not be detailed here.

[0031] See Figures 1 to 3 Furthermore, the frame 100 includes two opposing upright plates 101, with a guide plate 102 inclined between the two upright plates 101. The receiving box 110 is located below the guide plate 102, thereby guiding the demolded tablets to the receiving box 110 through the guide plate 102. This helps to reduce the falling height of the tablets and reduce damage, and also helps to speed up the collection efficiency of the tablets.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
