Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pharmaceutical equipment, and specifically provides an oral solid tablet production device and method. Background Art
[0002] At present, with the booming development of the pharmaceutical industry, oral solid tablets have become one of the most widely used drug dosage forms due to their advantages such as accurate dosage, good stability, and convenient administration. With the continuous growth of medical needs and the increasingly fierce competition in the pharmaceutical market, extremely stringent requirements have been put forward for oral solid tablet production equipment in terms of production efficiency, product quality, and cost control.
[0004] The layout of each component of traditional equipment is scattered, lacking systematic collaborative design. Different processes such as raw material mixing, tablet pressing, and collection are often completed by independent modules, and there is no effective linkage mechanism between these modules. This results in a large amount of waiting time between processes. For example, after the raw material mixing is completed, manual labor or complex transfer equipment is required to transfer the mixed raw materials to the pressing process, which not only consumes time but also is prone to transfer failures. Moreover, during the replacement and adjustment of the tablet plate of traditional equipment, it usually requires long-term shutdown, interrupting the continuity of the production process, with a long overall production cycle and unable to meet the large-scale and high-efficiency production requirements.
[0005] In addition, the traditional tablet collection process lacks effective dust treatment measures. A large amount of dust carried on the surface of the tablets will not only pollute the production environment and endanger the health of operators, but also may affect the appearance quality and drug release performance of the tablets, reducing the market competitiveness of the drugs.
[0006] At the same time, cost control is also a major problem faced by traditional production devices. Due to the lack of an effective raw material recycling mechanism, a large amount of residual drug powder generated during the production process is directly discarded, causing serious raw material waste. For some expensive drug raw materials, this waste phenomenon is particularly prominent, significantly increasing the production cost. At the same time, traditional equipment has a complex structure and numerous components, not only with a high equipment purchase cost, but also with high maintenance difficulty and high maintenance cost, further increasing the economic burden on enterprises.
[0007] In summary, the development of a new type of oral solid tablet production device that can significantly improve production efficiency, ensure product quality stability, and effectively reduce production costs has become an urgent need in the pharmaceutical industry in China. The present invention precisely addresses the above problems and provides an oral solid tablet production device and its production method with a compact layout, high-efficiency collaborative work, continuous production capability, guaranteed product quality, and cost reduction.

[0010] Furthermore, the hydraulic device includes a hydraulic press fixedly installed above the hydraulic tank. A hydraulic plate is fixedly arranged below the hydraulic press. A positioning plate is fixedly arranged on one side of the hydraulic plate. The positioning plate is movably adapted to the positioning slide rail.

A number of pop-up rods adapted to the tablet plate are evenly arranged below the pop-up plate. A positioning plate is also fixedly arranged on the side of the pop-up plate.
[0011] Furthermore, the support device includes a support box fixedly installed above the bracket. A number of hydraulic rods are fixedly arranged above the support box. The hydraulic rods are adapted to the tablet plate. A number of collection grooves are opened on the surface of the support box. A conical box is fixedly arranged on the inner wall of the support box. A sleeve is fixedly arranged on the inner wall of the conical box.
[0012] Furthermore, the circulation device includes a feeding box fixedly installed on one side of the hydraulic tank. A feeding port is arranged above the feeding box. A feeding pipe is fixedly arranged below the feeding box. An electromagnetic valve is arranged on the surface of the feeding pipe. A powder suction machine is fixedly arranged on one side of the feeding box. A circulation pipe is arranged at the feeding end of the powder suction machine. The other end of the circulation pipe communicates with the conical box.
[0013] Further, the mixing device includes a mixing gear adaptively installed at the other end of the conveyor belt. Above the mixing gear, a mixing rod is fixedly provided. Above the mixing rod, a mixing damping rod is fixedly provided. Above the mixing damping rod, a mixing plate is fixedly provided. On both sides of the mixing plate symmetrically, mixing wiping plates are provided. One side of the mixing wiping plate is provided with an oblique angle adapted to the placement groove.
[0014] Further, the collection device includes a collection box fixedly installed on one side of the inner wall of the hydraulic tank. Below the inner wall of the collection box, a collection gear is provided. The collection gear meshes with the first gear. On one side of the inner wall of the collection box, a baffle is fixedly provided. On one side of the collection box, a collection inclined plate is fixedly provided. Inside the collection inclined plate, a number of dust meshes are evenly provided. Below the collection inclined plate, a convergence box is fixedly provided. Inside the convergence box, a convergence plate is movably provided.
[0015] Further, a method for an oral solid tablet production device includes the following steps: S1: Pour the raw material dust into the feeding box, connect the power supply, turn on the control device, and perform an initialization operation on the equipment; S2: For the first tablet pressing operation, send an instruction through the control device to control the lifting telescopic rod to perform telescopic actions; the lifting telescopic rod pushes the lifting motor and the lifting rod downward, and the lifting rod drives the lifting plate at one end to descend synchronously, thereby causing the tablet plate to move downward until the tablet plate contacts the hydraulic rod of the support device. At this time, the hydraulic rod seals the bottom of the pressing groove of the tablet plate, and at the same time, the mixing wiping plate is in the placement groove; S3: After confirming the contact between the tablet plate and the hydraulic rod, use the control device to control the solenoid valve to open, so that the raw material dust in the feeding box is scattered onto the surface of the tablet plate through the feeding pipe; S4: Use the control device to start the drive motor. The drive motor drives the first gear and the second gear to start rotating. The rotation of the second gear drives the conveyor belt to rotate. The conveyor belt then drives the mixing gear to rotate. The mixing gear drives the mixing rod above to rotate. The mixing rod drives the mixing damping rod to rotate. The mixing damping rod drives the mixing wiping plate to rotate. Since the oblique angle on one side of the mixing wiping plate contacts the oblique angle on one side of the placement groove, the mixing wiping plate drives the mixing damping rod to extend, causing the mixing wiping plate to move out of the placement groove and rotate on the surface of the tablet plate. The mixing wiping plate levels the powder on the surface of the tablet plate, and smears the powder into several pressing grooves on the surface of the tablet plate until the pressing grooves are fully filled with powder; S5: When the pressing grooves are fully filled with powder, use the control device to stop the operation of the drive motor, so that the mixing wiping plate is restored to be placed in the placement groove to prevent interference with the operation during the subsequent tablet pressing hydraulic work; S6: Use the control device to start the hydraulic press. The hydraulic press drives the hydraulic plate to move downward. The hydraulic plate contacts the tablet plate to press the powder in the pressing grooves and complete the tablet production work; S7: After tableting is completed, the control device is used to control the lifting and telescopic rod to rise, so that the tablet plate is separated from the hydraulic rod. Since the pressed medicine powder has become a sheet, it will be fully filled in the pressing groove in the tablet plate and will not fall off. At this time, the lifting motor is started to drive the lifting rod to rotate, and the lifting rod drives the tablet plates on both sides to rotate 180 degrees; during this process, the angle sensor monitors the rotation angle in real time. When it rotates to 180 degrees, the lifting motor stops rotating. At this time, the tablet plate that has completed tableting is above the collection box, and the tablet plate without tablets rotates to above the supporting device.
[0016] Furthermore, a new round of tableting preparation is carried out on the tablet plate rotated above the supporting device, and a new round of tableting operation is carried out. During the second and subsequent tableting operations, when the hydraulic press drives the hydraulic plate to descend for tableting operation, the hydraulic plate will drive the ejection plate on one side to descend at the same time, and the ejection rod under the ejection plate is inserted into the pressing groove of the tablet plate to eject the prepared tablets, so that the tablets fall into the collecting box. At the same time, the operation of the transmission motor drives the second gear to rotate, and the second gear drives the collecting gear to rotate. The rotation of the collecting gear drives the tablets in the collecting box to rotate. The tablets are blocked by the baffle during the rotation, and thus move to the collecting inclined plate, and finally the collection of the tablets is completed. When the tablet plate is separated from the hydraulic rod, the residual powder falls into the conical box through the collecting groove, and is gathered into the circulation pipe through the conical box. The control device is used to start the powder suction machine, which sucks the powder in the conical box into the feed box, completing the recycling of the powder, reducing the waste of powder and the hindrance to the tableting work.
[0017] The beneficial effects of this technical solution are: (1) The components of the device of the present invention are compactly arranged and work well with each other. The transmission motor in the transmission device serves as the power core, and can provide power to the mixing device and the collecting device at the same time through the first gear, the second gear and the transmission belt. The mixing device can quickly and evenly mix the raw material dust and fill it into the pressing groove of the tablet plate, while the collecting device can collect the pressed tablets in time. This multi-component collaborative working mode avoids the waiting time between the various processes in traditional equipment, greatly shortens the entire production cycle, and significantly improves production efficiency.
[0018] (2) The design of the lifting device and tablet plate enables the production process to proceed continuously. After completing a tablet pressing operation, the lifting telescopic rod can quickly lift the tablet plate and rotate the lifting motor to transfer the pressed tablets to the top of the collection device for collection. At the same time, the empty tablet plate on the other side is transferred to the top of the support device for a new round of tablet pressing. This continuous alternating working mode does not require long-term shutdown for tablet plate replacement or adjustment, which ensures the continuity of production and further improves production efficiency.
[0019] (3) The hydraulic press of the hydraulic device can provide strong and stable pressure, causing the hydraulic plate to quickly descend to press the powder in the tablet plate, ensuring the formation of tablets in a short time. Moreover, during the second and subsequent tablet pressing operations, when the hydraulic plate descends, it will drive the ejection plate and ejection rod to quickly eject the pressed tablets into the collection box. This function of rapid pressing and ejection reduces the residence time of the tablets in the pressing grooves, speeds up the rhythm of the entire production process, and improves production efficiency.
[0020] (4) When the mixing and smoothing plate of the mixing device rotates on the surface of the tablet plate, through the cooperation with the bevel angle of the placement groove, it can fully stir and smooth the powder. The setting of the mixing damping rod enables the mixing and smoothing plate to adaptively adjust according to the accumulation of the powder during the rotation process, ensuring that the powder is evenly filled into each pressing groove of the tablet plate. The uniform filling of the raw materials guarantees the consistency of the composition and weight of each pressed tablet, improving the quality stability of the product.
[0021] (5) A number of dust nets are evenly arranged on the inner wall of the collection inclined plate in the collection device. During the tablet collection process, the dust nets can effectively filter out the dust carried on the surface of the tablets. This not only improves the production environment, reduces the harm of dust to the health of operators, but also avoids the impact of dust on the quality of the tablets.
[0022] (6) The setting of the circulation device realizes the efficient recycling of raw materials. When the tablet plate detaches from the hydraulic rod, the remaining powder falls into the conical box through the collection groove and is then sucked back into the feeding box by the powder suction machine through the circulation pipe. This raw material circulation mechanism greatly reduces the waste of raw materials and lowers the production cost. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0026] The specific implementation process is as follows: Embodiment 1: Please refer to Figures 1 - 5, a technical solution provided by the present invention: an oral solid tablet production device and method, including a bracket 1. The bracket 1 serves as the support structure of the entire device, providing an installation basis for other components, ensuring the stability and firmness of the device, enabling it to withstand the weights of various components and various forces generated during operation during the production process. A transmission device 2 is fixedly installed above the bracket 1. The transmission device 2 includes a transmission motor 201 fixedly installed on the inner wall of the bracket 1. A first gear 202 and a second gear 203 are fixedly installed at the output end of the transmission motor 201. A transmission belt 204 is adaptively installed on the surface of the second gear 203. The transmission motor 201 serves as the power source, generating rotational power after being powered on. The first gear 202 and the second gear 203 transmit and distribute the power of the transmission motor 201. Among them, the second gear 203 is connected to a mixing gear 701 in the mixing device 7 through the transmission belt 204, transmitting the power to the mixing device 7, enabling the mixing device 7 to perform mixing operations on the raw materials; at the same time, the first gear 202 meshes with a collecting gear 802 in the collecting device 8, driving the collecting device 8 to perform actions related to collecting the pressed tablets. A hydraulic tank 3 is fixedly installed above the bracket 1. The hydraulic tank 3 is mainly used to accommodate the hydraulic device 5 and provide an installation space for the lifting device 4, etc. Positioning slide rails 301 are symmetrically opened on the inner wall of the hydraulic tank 3. The positioning slide rails 301 provide an accurate movement track for a positioning plate 503 in the hydraulic device 5, enabling the hydraulic plate 502 to maintain stability and accuracy during the up and down movement, thereby ensuring the precision and reliability of the pressing operation on the powder in the tablet plate 408. A lifting device 4 is installed on the inner wall of the hydraulic tank 3. The lifting device 4 includes a lifting telescopic rod 401 fixedly installed above the hydraulic tank 3. A lifting motor 402 is fixedly installed below the lifting telescopic rod 401. A lifting rod 403 is fixedly installed at the output end of the lifting motor 402. An angle sensor 404 is fixedly installed below the lifting rod 403. Lifting plates 405 are fixedly installed on both sides of the angle sensor 404. Lifting damping rods 406 are fixedly installed inside the lifting plates 405. A lifting connecting plate 407 is fixedly installed above the lifting damping rods 406. One end of the lifting connecting plate 407 is fixedly installed with a tablet plate 408. A placement groove 409 is opened in the middle of the tablet plate 408. One side of the placement groove 409 has an inclined angle. The lifting telescopic rod 401 controls the lifting height of the tablet plate 408 through telescopic movement. When raw material filling is required, it descends so that the tablet plate 408 contacts the hydraulic rod 602 of the support device 6; after pressing is completed, it rises so that the tablet plate 408 disengages from the hydraulic rod 602. After the lifting motor 402 is started, it can drive the lifting rod 403 to rotate, thereby realizing the rotation action of the tablet plate 408, so as to transfer the pressed tablets above the collecting device 8 and rotate the empty tablet plate 408 back above the support device 6 for a new round of operations. The angle sensor 404 real-time monitors the rotation angle of the lifting rod 403 to ensure that the tablet plate 408 can accurately rotate 180 degrees. The lifting damping rods 406 play a role in buffering and stabilizing, avoiding violent vibrations during the lifting process, and ensuring the stable lifting of the tablet plate 408.A hydraulic device 5 is fixedly installed inside the hydraulic tank 3. The hydraulic device 5 includes a hydraulic press 501 fixedly installed above the hydraulic tank 3. A hydraulic plate 502 is fixedly installed below the hydraulic press 501. A positioning plate 503 is fixedly installed on one side of the hydraulic plate 502. The positioning plate 503 is movably adapted to the positioning slide rail 301. A hydraulic connecting plate 504 is fixedly installed on the other side of the hydraulic plate 502. One end of the hydraulic connecting plate 504 is fixedly installed with a pop-up plate 505. A number of pop-up rods 506 adapted to the tablet plate 408 are evenly installed below the pop-up plate 505. Positioning plates 503 are also fixedly installed on the side of the pop-up plate 505. When the hydraulic press 501 works, it generates a powerful pressure, pushing the hydraulic plate 502 to move downward along the positioning slide rail 301 to press the powder filled in the tablet plate 408 to form solid tablets. In the second and subsequent tablet pressing operations, when the hydraulic plate 502 descends, the pop-up plate 505 is driven to descend synchronously through the hydraulic connecting plate 504. The pop-up rods 506 below the pop-up plate 505 are inserted into the pressing grooves of the tablet plate 408 to eject the pressed tablets from the pressing grooves so as to fall into the collecting device 8 for collection. The cooperation between the positioning plate 503 and the positioning slide rail 301 ensures the stability and accuracy of the hydraulic plate 502 and the pop-up plate 505 during the movement. A support device 6 is fixedly installed on one side of the inner wall of the hydraulic tank 3. The support device 6 includes a support box 601 fixedly installed above the bracket 1. A number of hydraulic rods 602 are fixedly installed above the support box 601. The hydraulic rods 602 are adapted to the tablet plate 408. A number of collecting grooves 603 are formed on the surface of the support box 601. A conical box 604 is fixedly installed on the inner wall of the support box 601. A sleeve 605 is fixedly installed on the inner wall of the conical box 604. The support box 601 is used to carry and support components such as the hydraulic rods 602. When the tablet plate 408 descends in place, the hydraulic rods 602 are in close contact with the tablet plate 408 to seal the bottom of the pressing grooves of the tablet plate 408 to prevent powder leakage and at the same time provide stable support for the tablet plate 408. The collecting grooves 603 are used to collect the residual powder dropped when the tablet plate 408 separates from the hydraulic rods 602. These powders fall into the lower conical box 604 under the action of gravity. The shape design of the conical box 604 is conducive to the convergence of the powder so that it can smoothly enter the circulation pipe 904 to realize the recycling of the powder. The sleeve 605 plays a role in protecting and positioning the mixing rod 702 to ensure the stability of the device operation. A mixing device 7 is movably installed on the surface of the support device 6. The mixing device 7 includes a mixing gear 701 adapted to be installed at the other end of the transmission belt 204. A mixing rod 702 is fixedly provided above the mixing gear 701. A mixing damping rod 703 is fixedly installed above the mixing rod 702. A mixing plate 704 is fixedly installed above the mixing damping rod 703. Mixing wiping plates 705 are symmetrically installed on the side of the mixing plate 704. The installation angle on one side of the mixing wiping plate 705 is adapted to the placement groove 409. When the transmission belt 204 rotates driven by the second gear 203, the transmission belt 204 drives the mixing gear 701 to rotate.The mixing gear 701 drives the mixing rod 702, the mixing damping rod 703, the mixing plate 704 and the mixing wiping plate 705 to rotate in sequence. The mixing wiping plate 705 is initially located in the placement groove 409. As it rotates, due to the contact between the bevel angle on one side of it and the bevel angle on one side of the placement groove 409, the mixing wiping plate 705 drives the mixing damping rod 703 to extend, so as to move out of the placement groove 409 and rotate on the surface of the tablet plate 408. During the rotation process, the mixing wiping plate 705 evenly levels the medicinal powder scattered on the surface of the tablet plate 408 and fills it into the pressing grooves of the tablet plate 408, ensuring that the filling amount of the medicinal powder in each pressing groove is uniform, laying a foundation for pressing tablets with stable quality in the follow-up. The mixing damping rod 703 also plays a role in buffering and stabilizing the movement of the mixing wiping plate 705, ensuring the smoothness of the mixing operation. On the other side of the inner wall of the hydraulic tank 3, a collection device 8 is fixedly installed. The collection device 8 includes a collection box 801 fixedly installed on one side of the inner wall of the hydraulic tank 3. Below the inner wall of the collection box 801, a collection gear 802 is installed. The collection gear 802 meshes with the first gear 202. On one side of the inner wall of the collection box 801, a baffle 803 is fixedly installed. On one side of the collection box 801, a collection inclined plate 804 is fixedly installed. A number of dust nets 805 are evenly installed on the inner wall of the collection inclined plate 804. Below the collection inclined plate 804, a converging box 806 is fixedly installed. A converging plate 807 is movably installed in the converging box 806. When the first gear 202 rotates driven by the transmission motor 201, the collection gear 802 meshing with the first gear 202 rotates accordingly. The collection gear 802 drives the tablets in the collection box 801 to rotate. During the rotation process, the tablets are blocked by the baffle 803 and change the movement direction, so that they slide down along the collection inclined plate 804. The dust nets 805 on the inner wall of the collection inclined plate 804 filter the dust generated during the sliding process of the tablets, purifying the production environment and avoiding dust pollution of the tablets at the same time. The tablets after filtration fall onto the converging plate 807 in the converging box 806, completing the collection work of the tablets. The converging plate 807 can be conveniently taken out for subsequent processing of the collected tablets. Below the support device 6, a circulation device 9 is fixedly installed. The circulation device 9 includes a feeding box 901 fixedly installed on one side of the hydraulic tank 3. Above the feeding box 901, a feeding port 902 is installed. Below the feeding box 901, a feeding pipe 905 is fixedly installed. An electromagnetic valve is installed on the surface of the feeding pipe 905. On one side of the feeding box 901, a powder suction machine 903 is fixedly installed. The feeding end of the powder suction machine 903 is installed with a circulation pipe 904. The other end of the circulation pipe 904 communicates with the conical box 604. The feeding box 901 is used to store the raw material dust required for production. By controlling the opening and closing of the electromagnetic valve on the surface of the feeding pipe 905, the spreading amount and spreading timing of the raw material dust can be accurately controlled. When the tablet plate 408 is separated from the hydraulic rod 602, the residual medicinal powder falls into the conical box 604 through the collection groove 603. At this time, the powder suction machine 903 is started. The powder suction machine 903 generates a strong suction force to suck the medicinal powder in the conical box 604 back into the feeding box 901 through the circulation pipe 904, realizing the recycling of the medicinal powder, reducing raw material waste and pollution to the production environment.Meanwhile, it also avoids the obstruction to the tablet pressing work caused by the accumulation of medicine powder. A control device 10 is installed on one side of the hydraulic tank 3. As the control core of the whole device, the control device 10 precisely controls various components such as the drive motor 201 of the transmission device 2, the lifting telescopic rod 401 and the lifting motor 402 of the lifting device 4, the hydraulic press 501 of the hydraulic device 5, the powder suction machine 903 of the circulation device 9, and the solenoid valve of the feeding pipe 905 through the preset program and the instructions input by the operator, realizes the coordinated work among the components, and ensures the smooth progress of the whole production process; In use, the operator inputs an instruction on the control device 10 to start the contraction of the lifting telescopic rod 401. The lifting telescopic rod 401 pushes the lifting motor 402 and the lifting rod 403 to move slowly downward. The lifting rod 403 drives the lifting plate 405, the lifting damping rod 406, the lifting connecting plate 407, and the tablet plate 408 to descend synchronously. When the tablet plate 408 approaches the hydraulic rod 602 of the support device 6, the descending speed slows down until the tablet plate 408 is in close contact with the hydraulic rod 602. At this time, the hydraulic rod 602 seals the bottom of the pressing groove of the tablet plate 408 to prevent the leakage of the powder, and at the same time ensures that the mixing wiping plate 705 is in the placement groove 409. After confirming that the tablet plate 408 and the hydraulic rod 602 are well sealed, the solenoid valve on the surface of the feed pipe 905 is controlled to open. The raw material dust in the feed box 901, under the action of gravity, is evenly scattered on the surface of the tablet plate 408 through the feed pipe 905. During the feeding process, the feeding amount is adjusted by controlling the opening time of the solenoid valve and the diameter of the feed pipe 905 to meet the requirements of different tablet production. The operator starts the drive motor 201 through the control device 10. The drive motor 201 runs at a high speed, and its output shaft drives the first gear 202 and the second gear 203 to rotate rapidly. The second gear 203 transmits the power to the mixing gear 701 through the transmission belt 204. The mixing gear 701 drives the mixing rod 702, the mixing damping rod 703, and the mixing plate 704 to rotate synchronously. Since the bevel angle on one side of the mixing wiping plate 705 cooperates with the bevel angle on one side of the placement groove 409, as the mixing wiping plate 705 rotates, the mixing damping rod 703 gradually elongates, causing the mixing wiping plate 705 to move out of the placement groove 409 and make a circular motion on the surface of the tablet plate 408. During the rotation process, the mixing wiping plate 705 continuously stirs and levels the powder on the surface of the tablet plate 408 and fills it into each pressing groove on the surface of the tablet plate 408. This process continues until the pressing grooves are fully filled with powder. When the pressing grooves are fully filled with powder, the operator stops the operation of the drive motor 201 through the control device 10. As the drive motor 201 stops rotating, the first gear 202, the second gear 203, the transmission belt 204, and the various components of the mixing device 7 also gradually stop moving. The mixing wiping plate 705 finally returns to the placement groove 409 to prevent interference with the operation during the subsequent hydraulic tablet production. The operator starts the hydraulic press 501 through the control device 10. The hydraulic press 501 starts to work, generating a strong pressure to push the hydraulic plate 502 downward. The positioning plate 503 on one side of the hydraulic plate 502 slides smoothly in the positioning slide rail 301 on the inner wall of the hydraulic tank 3 to ensure that the hydraulic plate 502 descends vertically. When the hydraulic plate 502 contacts the tablet plate 408, the pressure is gradually applied to the powder in the pressing groove, and the powder is compacted under the action of the pressure to form solid tablets. During the pressing process, according to the hardness requirements of the tablets, the operator can adjust the pressure magnitude and the pressing time of the hydraulic press 501 through the control device 10. After the tablet pressing is completed, the operator starts the elongation of the lifting telescopic rod 401 through the control device 10,The lifting telescopic rod 401 drives the lifting motor 402, the lifting rod 403, the lifting plate 405 and the tablet plate 408 to slowly rise, so that the tablet plate 408 is separated from the hydraulic rod 602. Since the pressed powder has become sheet-shaped and is tightly filled in the pressing grooves in the tablet plate 408 and will not fall off. When the tablet plate 408 rises to a certain height, the lifting motor 402 is started. The lifting motor 402 drives the lifting rod 403 to rotate, and the lifting rod 403 drives the tablet plates 408 on both sides to rotate synchronously by 180 degrees. During the rotation process, the angle sensor 404 monitors the rotation angle in real time and feeds the data back to the control device 10. When the angle sensor 404 detects that the rotation angle reaches 180 degrees, the control device 10 immediately controls the lifting motor 402 to stop rotating. At this time, the tablet plate 408 with the tablets pressed is above the collection box 801, and the tablet plate 408 without tablets rotates to above the support device 6; Second and subsequent tablet pressing operations: When the hydraulic press 501 drives the hydraulic plate 502 to descend again for the tablet pressing operation, different from the first tablet pressing, the hydraulic plate 502 will drive the ejector plate 505 on one side to descend simultaneously through the hydraulic connection plate 504. The ejector rods 506 evenly distributed below the ejector plate 505 accurately insert into the pressing grooves of the tablet plate 408 as the ejector plate 505 descends. When the ejector rods 506 contact the tablets in the pressing grooves, the continuously descending ejector plate 505 ejects the tablets from the pressing grooves, causing the tablets to fall into the collection box 801. At the same time, the transmission motor 201 keeps running, driving the second gear 203 to rotate. The second gear 203 drives the collection gear 802 to rotate. The rotation of the collection gear 802 drives the tablets in the collection box 801 to rotate. During the rotation process, the tablets are blocked by the baffle 803, changing the movement direction and gradually moving to the collection inclined plate 804. The dust screens 805 evenly arranged on the inner wall of the collection inclined plate 804 filter and absorb the dust generated by the tablets, removing the dust on the surface and ensuring the cleanliness of the tablets. Finally, the cleaned tablets slide down along the collection inclined plate 804 and fall onto the converging plate 807 in the converging box 806, completing the collection of the pressed tablets; During the process of the tablet plate 408 detaching from the hydraulic rod 602, due to the lifting and rotation of the tablet plate 408, a small amount of residual powder will fall from the tablet plate 408. These residual powders flow into the conical box 604 under the action of gravity through the collection groove 603 on the surface of the support box 601. When the control device 10 detects that the tablet plate 408 has completed a tablet pressing cycle and detached from the hydraulic rod 602, the powder suction machine 903 is started. The powder suction machine 903 generates a strong suction force, and sucks the powder in the conical box 604 into the feeding box 901 through the circulation pipe 904. During the suction process, the powder passes through the filtration and purification of the circulation pipe 904, removes impurities and then returns to the feeding box 901, mixes with the newly added raw materials, realizing the recycling of raw materials. This not only reduces the waste of raw materials, but also reduces the production cost. At the same time, it avoids the pollution of the production environment and equipment by the residual powder, ensuring the smooth progress of the tablet pressing work; Repeat the tablet pressing operation. For the tablet plate 408 rotated above the support device 6, repeat a new round of tablet pressing operation according to the steps of the first tablet pressing operation. In this way, it circulates until the production task of the required number of tablets is completed. During the whole production process, the control device 10 monitors the running states and production parameters of each component in real time, such as the rotation speed of the drive motor 201, the pressure of the hydraulic press 501, the position and angle of the lifting device 4, etc., and automatically adjusts and controls according to the preset production program and parameters to ensure the stability of the production process and the consistency of product quality.
[0027] Embodiment 2: Please refer to Figures 1 - 5 , a technical solution provided by the present invention: a method for an oral solid tablet production device, including the following steps: S1: Pour the raw material dust into the feeding box 901, turn on the power supply, turn on the control device 10, and perform an initialization operation on the equipment; S2: First tablet pressing operation. Send an instruction through the control device 10 to control the telescopic movement of the lifting telescopic rod 401; the lifting telescopic rod 401 pushes the lifting motor 402 and the lifting rod 403 to move downward, and the lifting rod 403 drives the lifting plate 405 at one end to descend synchronously, thereby causing the tablet plate 408 to move downward until the tablet plate 408 contacts the hydraulic rod 602 of the support device 6. At this time, the hydraulic rod 602 seals the bottom of the pressing groove of the tablet plate 408, and at the same time, the mixing wiping plate 705 is in the placement groove 409; S3: After confirming the contact between the tablet plate 408 and the hydraulic rod 602, use the control device 10 to control the solenoid valve to open, so that the raw material dust in the feeding box 901 is scattered onto the surface of the tablet plate 408 through the feeding pipe 905; S4: Use the control device 10 to start the drive motor 201. The drive motor 201 drives the first gear 202 and the second gear 203 to start rotating. The rotation of the second gear 203 drives the conveyor belt 204 to rotate. The conveyor belt 204 then drives the mixing gear 701 to rotate. The mixing gear 701 drives the upper mixing rod 702 to rotate. The mixing rod 702 drives the mixing damping rod 703 to rotate. The mixing damping rod 703 drives the mixing wiper 705 to rotate. Since the bevel angle on one side of the mixing wiper 705 contacts the bevel angle on one side of the placement groove 409, the mixing wiper 705 drives the mixing damping rod 703 to extend, causing the mixing wiper 705 to move out of the placement groove 409 and rotate on the surface of the tablet plate 408. The mixing wiper 705 levels the powder on the surface of the tablet plate 408 and smears the powder into several pressing grooves on the surface of the tablet plate 408 until the pressing grooves are fully filled with powder; S5: When the pressing grooves are fully filled with powder, use the control device 10 to stop the operation of the drive motor 201, so that the mixing wiper 705 is restored to be placed in the placement groove 409 to prevent interference with the operation during subsequent tablet pressing hydraulic work; S6: Use the control device 10 to start the hydraulic press 501. The hydraulic press 501 drives the hydraulic plate 502 to move downward. The hydraulic plate 502 contacts the tablet plate 408 to press the powder in the pressing grooves and complete the tablet pressing work; S7: After tablet pressing is completed, use the control device 10 to control the lifting telescopic rod 401 to rise, so that the tablet plate 408 is separated from the hydraulic rod 602. Since the pressed powder has become tablet-shaped and will fully fill the pressing grooves in the tablet plate 408 and will not fall off, at this time, start the lifting motor 402 to drive the lifting rod 403 to rotate. The lifting rod 403 drives the tablet plates 408 on both sides to rotate 180 degrees; during this process, the angle sensor 404 monitors the rotation angle in real time. When it rotates to 180 degrees, the lifting motor 402 stops rotating. At this time, the tablet plate 408 with tablet pressing completed is above the collection box 801, and the tablet plate 408 without tablets rotates to above the support device 6; According to S7, a new round of tablet pressing preparation is carried out on the tablet board 408 rotated above the support device 6, and a new round of tablet pressing operation is performed. During the second and subsequent tablet pressing operations, when the hydraulic press 501 drives the hydraulic plate 502 to descend for the tablet pressing operation, the hydraulic plate 502 will drive the ejection plate 505 on one side to descend simultaneously. The ejection rod 506 below the ejection plate 505 is inserted into the pressing groove of the tablet board 408 to eject the formed tablets, so that the tablets fall into the collection box 801. At the same time, the drive motor 201 operates to drive the second gear 203 to rotate. The second gear 203 drives the collection gear 802 to rotate. The rotation of the collection gear 802 drives the tablets in the collection box 801 to rotate. The tablets are blocked by the baffle 803 during the rotation process, and thus move to the collection inclined plate 804, and finally the collection of the tablets is completed. When the tablet board 408 disengages from the hydraulic rod 602, the residual powder falls into the conical box 604 through the collection groove 603, and converges into the circulation pipe 904 through the conical box 604. The control device 10 is used to start the powder suction machine 903. The powder suction machine 903 sucks the powder in the conical box 604 into the feeding box 901 to complete the recycling of the powder, reduce the waste of powder and the obstruction to the tablet pressing work.
[0028] Working principle: During production, the drive motor 201 of the drive device 2 drives the first and second gears to rotate. The second gear 203 drives the mixing gear 701 of the mixing device 7 to operate through the transmission belt 204, and drives the mixing wiping plate 705 to mix and level the raw materials. At the same time, the first gear 202 drives the collection gear 802 of the collection device 8 for subsequent tablet collection. The lifting device 4 controls the lifting motor 402 and the lifting rod 403 by the lifting telescopic rod 401 to realize the lifting and 180-degree rotation of the tablet board 408. The angle sensor 404 ensures the rotation accuracy. The hydraulic press 501 of the hydraulic device 5 generates pressure to push the hydraulic plate 502, and slides on the positioning slide rail 301 through the positioning plate 503 to ensure smooth movement and press the powder in the pressing groove. During the second and subsequent tablet pressing, it can also drive the ejection plate 505 and the ejection rod 506 to eject the pressed tablets. The hydraulic rod 602 of the support device 6 seals the bottom of the pressing groove of the tablet board 408. The collection groove 603 collects the residual powder, which converges into the circulation pipe 904 through the conical box 604. The circulation device 9 controls the raw material distribution through the feeding pipe 905 and the solenoid valve. The powder suction machine 903 sucks the residual powder in the conical box 604 back into the feeding box 901 for recycling. In the collection device 8, the collection gear 802 drives the tablets to rotate. The baffle 803 blocks them and makes them move to the collection inclined plate 804. After the dust net 805 filters the dust, the tablets fall into the converging box 806 to complete the collection.
