Description

Technical Field

[0001] This invention relates to the field of pharmaceutical tablet processing technology, and in particular to a tablet compression mold for medicinal fungal extract tablets. Background Technology

[0002] Medicinal fungal extracts, rich in polysaccharides, terpenes, sterols, alkaloids, proteins, and other active ingredients, possess excellent health and medicinal value and are often formulated into tablets for easy consumption and storage. One of the core processes in tablet preparation is tablet compression, which involves using a tableting mold to compress the powder or granules of medicinal fungal extract into tablets with a specific shape and hardness.

[0003] Currently, the tableting production of medicinal fungal extract tablets mainly utilizes conventional pharmaceutical tableting molds. However, existing molds have significant shortcomings in practical applications. Medicinal fungal extracts typically possess a certain degree of viscosity and hygroscopicity. During the tableting process, the material easily adheres to the punch surface (i.e., "punch sticking"), leading to defects on the tablet surface and severely affecting the product's appearance quality and content uniformity. Furthermore, the punches in conventional molds are not optimized for the characteristics of such viscous materials, making it difficult to effectively solve the punch sticking problem.

[0004] Therefore, there is an urgent need to develop a tablet compression mold for medicinal fungal extracts to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a tableting mold for medicinal fungal extracts, which solves the problems in the prior art where the stickiness and hygroscopicity of medicinal fungal extracts cause tablet sticking and defects on the tablet surface during compression, and the inability of existing molds to effectively optimize for sticky materials. This invention enables the upper and lower punches to actively demold via an ejector mechanism during the tableting process, completely preventing tablets from adhering to the punch surface. Simultaneously, it achieves fully automated continuous operation of feeding, scraping, tableting, demolding, ejecting, and collecting tablets, thereby improving the appearance quality and content uniformity of the tablets and increasing production efficiency.

[0006] To achieve the above objectives, the present invention provides the following solution: The present invention provides a tableting mold for medicinal fungal extracts, comprising: A base is provided, on which a plurality of first pillars, a plurality of second pillars, and a plurality of third pillars are fixedly connected.

The controller is fixedly connected to the base, and the first power mechanism, the second power mechanism, the pneumatic drive mechanism and the third power mechanism are all electrically connected to the controller.

[0007] Preferably, the feeding mechanism includes a top block and a movable block. Both the upper punch and the lower punch have cavities.

The top block is located within the first through hole, and the movable block is located within the cavity. The top block and the movable block are fixedly connected. The movable block extends into the cavity. A first spring is provided within the cavity and is sleeved on the top block. The pneumatic drive mechanism is drively connected to the movable block.

[0008] Preferably, the pneumatic drive mechanism includes several pressure tanks, each pressure tank being connected to an air source and a main air pipe. A solenoid valve is installed on the main air pipe. A first air passage is provided in both the upper punch and the lower punch. Several second air passages are provided in both the upper mold base and the lower mold base. The first air passages are connected to the second air passages. Several branch pipes are connected to the main air pipe, and the branch pipes are connected to the second air passages.

[0009] Preferably, the third power mechanism includes two motors, a plurality of fourth pillars are fixedly connected to the base, a mounting plate is fixedly connected to the fourth pillars, a rack is provided on the mounting plate, the material box is slidably connected to the mounting plate through a sliding mechanism, the motor is mounted on the material box, the motor is drivenly connected to the rack, and the motor is fixedly connected to the controller.

[0010] Preferably, the sliding mechanism includes a guide rod, connecting plates are fixedly connected to both sides of the material box, a slider is fixedly connected to the end of the connecting plate away from the material box, a groove is provided on the slider, and the guide rod is slidably disposed in the groove.

[0011] Preferably, a reinforcing plate is fixedly connected to the slider, the motor is fixedly connected to the reinforcing plate, a gear is fixedly connected to the motor drive shaft, a pad is fixedly connected to the mounting plate, the rack is fixedly connected to the pad, and the gear meshes with the rack.

[0012] Preferably, the first power mechanism includes a first cylinder, which is fixedly connected to the top plate, the output end of the first cylinder is fixedly connected to the upper mold base, and the first cylinder is electrically connected to the controller.

[0013] Preferably, the second power mechanism includes a second cylinder, which is fixedly connected to the base, the output end of the second cylinder is fixedly connected to the lower mold base, and the second cylinder is electrically connected to the controller.

[0015] Preferably, two material guide channels are fixedly connected to the intermediate mold, and a collection box is placed on the base, with the collection box located at the discharge end of the material guide channels.

[0016] The present invention discloses the following technical effects: 1. Effectively solves the problem of tablet sticking and improves tablet quality. This invention features ejector mechanisms on both the upper and lower punches, working in conjunction with a pneumatic drive mechanism. After tableting, the pneumatic drive mechanism activates the ejector mechanism to actively loosen and remove tablets or materials adhering to the punch end face, achieving active mechanical demolding. Compared to conventional molds that rely solely on gravity or scrapers for passive separation, this invention's active ejector method completely solves the "sticking" problem caused by the stickiness and hygroscopicity of medicinal fungal extracts, effectively preventing defects such as pitting, missing corners, and delamination on the tablet surface, and significantly improving the appearance quality and content uniformity of the tablets.

[0017] 2. Feeding and scraping are completed simultaneously, resulting in high feeding accuracy. The top and bottom of the material box of this invention are both open, and the bottom surface of the material box is in contact with the top surface of the middle mold. During the process of the third power mechanism driving the material box to move on the top surface of the middle mold, the material in the material box continuously falls into the mold hole. At the same time, the bottom surface of the material box can automatically scrape off the excess powder on the top surface of the middle mold. The two actions of feeding and scraping are completed simultaneously, which not only ensures that the amount of material in each mold hole is accurate and level, but also eliminates the need for an additional independent scraping device, simplifying the equipment structure and improving feeding efficiency and accuracy.

[0018] 3. High degree of automation, enabling continuous operation throughout the entire process. This invention uses a controller to centrally electrically control the first power mechanism, the second power mechanism, the third power mechanism, and the pneumatic drive mechanism. Each mechanism automatically completes the entire set of processes of feeding, scraping, tableting, demolding, tablet ejection, and tablet collection according to the time sequence preset by the controller. The entire tableting process does not require manual intervention, realizing fully automated continuous production, significantly reducing labor costs, improving production efficiency, eliminating human operation errors, and ensuring the stability of product quality between batches.

[0019] 4. Bidirectional compression results in uniform tablet density. This invention employs a bidirectional pressing method where a first power mechanism drives the upper mold base downward and a second power mechanism drives the lower mold base upward. The material inside the mold hole is simultaneously subjected to pressing forces from both above and below. Compared to unidirectional pressing, the material is compressed more fully and evenly within the mold hole, resulting in tablets with better density and hardness consistency. This effectively avoids the density difference problem between the upper and lower layers of the tablet that may be caused by unidirectional pressing.

[0020] 5. The material pushing and feeding are linked, resulting in a compact and efficient structure. The present invention has a pushing mechanism on both sides of the material box. During the process of the material box returning to the starting position, the pushing mechanism pushes the tablets that have been pressed and formed on the top surface of the middle mold to the designated area. At the same time, the material box completes the feeding action into the mold hole again. The two processes of pushing tablets and feeding are completed in a single reciprocating motion, which reduces unnecessary action steps, shortens the cycle time of a single tableting cycle, and further improves the overall production efficiency of the machine.

[0021] 6. Simultaneous compression of multiple pores results in high production efficiency. The present invention has several upper punches installed on the upper mold base, several lower punches installed on the lower mold base, and several mold holes correspondingly opened on the middle mold. It can simultaneously complete the pressing, demolding and collection of multiple tablets, greatly improving the output per unit time, and is suitable for the large-scale industrial production of medicinal fungal extract tablets.

[0022] This invention achieves active anti-sticking demolding by setting up a top material mechanism in conjunction with pneumatic drive. The material box moves synchronously to complete the feeding and scraping, and with the controller, it realizes fully automatic continuous tableting, effectively solving the sticking and punching problem and improving tablet quality and production efficiency.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figure 1-6 This invention provides a tableting mold for medicinal fungal extracts, comprising: The base 1 has several first pillars 2, several second pillars 3 and several third pillars 4 fixedly connected to it. The first pillars 2 have a top plate 5 fixedly connected to them to provide support for the upper structure. The second pillars 3 and the third pillars 4 have a middle mold 6 fixedly connected to them to ensure that the middle mold 6 remains absolutely stable during operation. The first pillars 2 have an upper mold base 7 slidably connected to them, and the third pillars 4 have a lower mold base 8 slidably connected to them to ensure the high precision and guidance of the movement of the upper and lower mold bases. The upper mold base 7 has several upper punches 9 installed on it, and the lower mold base 8 has several lower punches 10 installed on it, which can realize multi-hole simultaneous pressing and greatly improve production efficiency. Both the upper punch 9 and the lower punch 10 are equipped with ejector mechanisms to solve the problem of easy sticking of medicinal fungal extracts. The ejector mechanism is connected to a pneumatic drive mechanism, which uses compressed air as a power source, providing rapid response and clean, pollution-free operation. The top plate 5 is equipped with a first power mechanism, which provides the main driving force for the pressing action. The base 1 is equipped with a second power mechanism, which controls the lifting and lowering of the lower punch 10 to complete the loading, ejection, and resetting. The middle mold 6 has several mold holes 41, and the lower punch 10 extends into the mold holes 41. The upper punch 9 is correspondingly set with the mold holes 41. The three work together to complete the tablet forming within the mold holes 41. The end faces of both the upper punch 9 and the lower punch 10 are concave, which meets the shape requirements of the tablet. The feeding assembly includes a material box 11, which is open at both the top and bottom to facilitate the addition and falling of materials into the die hole 41. The material box 11 fits against the top surface of the middle die 6 to prevent material leakage during movement. A third power mechanism is provided on the base 1 to drive the material box 11 to move on the top surface of the middle die 6 to achieve automatic filling. Pushing mechanisms are provided on both sides of the material box 11 to push the finished tablets to one side while ensuring the cleanliness of the surface of the middle die 6. The controller 12 is fixedly connected to the base 1. The first power mechanism, the second power mechanism, the pneumatic drive mechanism and the third power mechanism are all electrically connected to the controller 12. The controller 12 can be a programmable logic controller (PLC) or a microcontroller. Through a preset program, it realizes the automated and intelligent control of the entire tableting process, ensuring that the timing of each action is accurate.

[0028] In operation, the controller 12 first activates the third power mechanism, driving the material box 11 to move above the die hole 41 of the middle mold 6. The medicinal fungal extract powder or granules in the material box 11 fall into the die hole 41 through its bottom opening and are supported by the lower punch 10. The material box 11 then moves to the other side. Because the bottom surface of the material box 11 is in contact with the upper surface of the middle mold 6, no excess powder overflows after the material box 11 passes through the die hole 41. The material box 11 also effectively scrapes away excess powder, ensuring accurate and uniform material quantity in each die hole 41. Next, the controller 12 activates the first and second power mechanisms, driving the upper mold base 7 and lower mold base 8 to move in opposite directions, respectively. The upper punch 9 extends into the die hole 41 and cooperates with the fixed lower punch 10 to apply bidirectional pressure to the material in the die hole 41, pressing it into shape. After compression, the upper die holder 7 drives the upper punch 9 to reset. During lifting, the pneumatic drive mechanism drives the ejector mechanism to disengage the upper punch 9 from the tablet. The second power mechanism drives the lower die holder 8 to continue moving upward, ejecting the formed tablet. Simultaneously, the ejector mechanism inside the lower punch 10 also operates under the action of the pneumatic drive mechanism, separating the tablet from the lower punch 10. Then, the material box 11 moves from one side to the other under the drive of the third power mechanism, pushing the formed tablet to one side of the middle die 6, allowing the tablet to fall into the designated area. During the movement of the material box 11, powder is also added into the die hole 41. Throughout the process, the controller 12 acts as the core, precisely controlling the action sequence, stroke, and time of each power mechanism to achieve automated and highly efficient tablet production.

[0029] The scheme is further optimized. The ejector mechanism includes an ejector block 13 and a movable block 14. A cavity 15 is opened in both the upper punch 9 and the lower punch 10. A first through hole is opened on the end face of both the upper punch 9 and the lower punch 10. The first through hole communicates with the cavity 15. The ejector block 13 is located in the first through hole, and the movable block 14 is located in the cavity 15. The ejector block 13 and the movable block 14 are fixedly connected. The movable block 14 extends into the cavity 15. A first spring 16 is provided in the cavity 15. The first spring 16 is sleeved on the ejector block 13. The pneumatic drive mechanism is connected to the movable block 14 for transmission.

[0030] The top block 13 is used to eject the tablet, separating it from the upper punch 9 or the lower punch 10, thus preventing the tablet from sticking to the punch. The pneumatic drive mechanism is used to provide air pressure into the cavity 15, which enables the movable block 14 to move quickly, while the movable block 14 can overcome the elastic force of the first spring 16.

[0031] When the ejection action is required, the pneumatic drive mechanism introduces compressed gas into the cavity 15. The air pressure pushes the movable block 14 outward against the elastic force of the first spring 16. The movable block 14 then drives the ejector block 13 to extend out of the first through hole, thereby loosening and removing the tablets or materials adhering to the punch end face. After the pneumatic drive mechanism releases pressure, the restoring force of the first spring 16 pulls the movable block 14 and the ejector block 13 back to their original positions, preparing for the next pressing. This mechanism is ingeniously designed, requiring no additional mechanical transmission, and directly utilizes pneumatic pressure to achieve ejection. It has a compact structure and reliable operation.

[0032] The scheme is further optimized. The pneumatic drive mechanism includes several pressure tanks 17. The pressure tanks 17 are connected to an air source and a main air pipe 18. A solenoid valve 19 is installed on the main air pipe 18. A first air passage 20 is opened in both the upper punch 9 and the lower punch 10. Several second air passages 21 are opened in both the upper mold base 7 and the lower mold base 8. The first air passages 20 are connected to the second air passages 21. Several branch pipes 22 are connected to the main air pipe 18. The branch pipes 22 are connected to the second air passages 21.

[0033] Pressure tank 17 serves as an air storage device to store and provide stable compressed air. Solenoid valve 19 is used to precisely control the opening and closing of the air passage. Solenoid valve 19 is a two-position three-way solenoid valve, which can realize rapid air supply, air cut-off and air release, and avoid airflow remaining in the first air passage 20 and the second air passage 21, which would affect the reset of the top block 13. The main air pipe 18, the first air passage 20 and the second air passage 21 constitute a complete gas passage from the outside to the top block 13 at the end face of the punch. The setting of branch pipe 22 ensures that each punch can obtain air pressure power independently or synchronously.

[0034] In operation, when the controller 12 issues a ejection command, the solenoid valve 19 opens, and the high-pressure gas in the pressure tank 17 flows sequentially through the main air pipe 18, branch pipe 22, second air passage 21, and first air passage 20, finally entering the cavity 15 and driving the ejector block 13 to move. By controlling the opening time and pressure of the solenoid valve 19, the ejection force and stroke of the ejector block 13 can be precisely adjusted. When the solenoid valve 19 is closed, since it is a two-position three-way solenoid valve, the air pressure in the second air passage 21 and the first air passage 20 can be released.

[0035] The scheme is further optimized. The third power mechanism includes two motors 23. Several fourth pillars 24 are fixedly connected to the base 1. A mounting plate 25 is fixedly connected to the fourth pillars 24. A rack 26 is provided on the mounting plate 25. The material box 11 is slidably connected to the mounting plate 25 through a sliding mechanism. The motor 23 is set on the material box 11. The motor 23 is connected to the rack 26 for transmission. The motor 23 is fixedly connected to the controller 12.

[0036] Motor 23 provides sufficient and stable power for the movement of material box 11. The sliding mechanism ensures the linearity and stability of the movement of material box 11. The transmission connection between motor 23 and rack 26 can convert the rotational motion of motor into the linear reciprocating motion of material box 11. When material needs to be added, controller 12 starts motor 23. Motor 23 cooperates with rack 26. Since rack 26 is fixed, motor 23 and material box 11 fixedly connected to it will move along the direction of rack 26, so that material box 11 moves on the top surface of intermediate mold 6. After the material is added, material box 11 will stay on the other side without returning.

[0037] The scheme is further optimized. The sliding mechanism includes a guide rod 27. Connecting plates 28 are fixedly connected to both sides of the material box 11. A slider 29 is fixedly connected to the end of the connecting plate 28 away from the material box 11. A groove is provided on the slider 29. The guide rod 27 is slidably disposed in the groove.

[0038] The guide rod 27 serves as a guide rail, and through the precise cooperation between the slider 29 and the guide rod 27, it provides low-friction, high-precision linear guidance for the material box 11, ensuring the accurate alignment and stable operation of the material box 11 with the top surface of the middle mold 6.

[0039] The scheme is further optimized. A reinforcing plate 30 is fixedly connected to the slider 29, the motor 23 is fixedly connected to the reinforcing plate 30, a gear 31 is fixedly connected to the drive shaft of the motor 23, a pad is fixedly connected to the mounting plate 25, and a rack 26 is fixedly connected to the pad. The gear 31 meshes with the rack 26.

[0040] The reinforcing plate 30 enhances the rigidity of the motor 23 installation. The gear 31 and rack 26 are engaged in a standard gear and rack transmission structure, which has high transmission efficiency, accurate positioning, and is easy to install and maintain. During operation, the motor 23 drives the gear 31 to rotate, and the gear 31 rolls on the rack 26, thereby realizing the sliding of the slider 29.

[0041] The scheme is further optimized. The first power mechanism includes a first cylinder 32, which is fixedly connected to the top plate 5. The output end of the first cylinder 32 is fixedly connected to the upper mold base 7. The first cylinder 32 is electrically connected to the controller 12.

[0042] The first cylinder 32, as an actuator, has the advantages of simple structure, rapid action and large output force. The supporting components of the first cylinder 32 all adopt existing technology. The controller 12 can accurately control the lifting action and pressing pressure of the upper mold base 7 by controlling the air intake and exhaust of the first cylinder 32.

[0043] The scheme is further optimized. The second power mechanism includes a second cylinder 33, which is fixedly connected to the base 1. The output end of the second cylinder 33 is fixedly connected to the lower mold base 8, and the second cylinder 33 is electrically connected to the controller 12.

[0044] In addition to providing the power for the lower punch 10 to rise and press and eject tablets, the second cylinder 33's descent action can also drive the lower punch 10 back to the loading position, preparing for the next feeding. The second cylinder 33 can be a servo cylinder for more precise extension.

[0045] The design is further optimized. The pushing mechanism includes a pushing plate 34, a number of straight rods 35 are fixedly connected to the material box 11, a number of sleeves 36 are fixedly connected to the pushing plate 34, a limit block 37 is fixedly connected to the straight rods 35, the limit block 37 is located inside the sleeve 36, the limit block 37 is slidably arranged inside the sleeve 36, and a second spring 38 is fixedly connected between the pushing plate 34 and the material box 11.

[0046] Under normal conditions, the pusher plate 34 maintains a certain distance from the material box 11 under the elastic force of the second spring 38. When the material box 11 moves to one side to add material under the drive of the motor 23, the pusher plate 34 moves accordingly. During the movement, the pusher plate 34 comes into contact with the molded tablet material accumulated on the top surface of the intermediate mold 6 and pushes the material forward. The buffering effect of the second spring 38 can prevent the pusher plate 34 from being damaged by rigid collision with hard obstacles.

[0047] The design is further optimized by fixing two material guide channels 39 on the middle mold 6 and placing a collection box 40 on the base 1. The collection box 40 is located at the discharge end of the material guide channel 39.

[0048] After the pusher plate 34 pushes the tablets on the surface of the intermediate mold 6 to one side of the intermediate mold 6, the tablets fall into the guide groove 39 and slide down along the guide groove 39 into the collection box 40. The collection box 40 can be easily removed.

[0049] The workflow is as follows: In the initial state, the upper mold base 7 is in a high position, the lower punch 10 is inserted into the mold hole 41 of the middle mold 6 and stays in the loading position, and the material box 11 is located at the starting position on one side of the middle mold 6.

[0050] The first step, feeding and scraping: Controller 12 activates the third power mechanism, and motor 23 drives gear 31 to roll on rack 26, causing material box 11 to move smoothly from one side of intermediate mold 6 to the other via sliding mechanism along guide rod 27. Because the bottom of material box 11 is open and fits against the top surface of intermediate mold 6, the medicinal fungal extract powder inside material box 11 continuously falls into the lower die hole 41 during the movement, where it is supported by the lower punch 10. When material box 11 reaches the end point on the other side, since the bottom surface of material box 11 fits against the upper surface of intermediate mold 6, material box 11 naturally scrapes away excess powder from the top surface of intermediate mold 6 after passing through die hole 41, ensuring that the amount of material in each die hole 41 is accurate and level.

[0051] The second step is bidirectional tableting: After feeding is complete, the controller 12 simultaneously activates the first and second power mechanisms. The first cylinder 32 drives the upper mold base 7 downward along the first support column 2, causing the upper punch 9 to extend into the mold hole 41; the second cylinder 33 drives the lower mold base 8 upward along the third support column 4, pushing the lower punch 10 upward within the mold hole 41. The upper punch 9 and the lower punch 10 apply bidirectional pressure to the material within the mold hole 41, compressing the medicinal fungal extract powder or granules into shape.

[0052] The third step is upper punch demolding: After pressing, controller 12 controls the first cylinder 32 to drive the upper mold base 7 and upper punch 9 to move upward and reset. At the same time, controller 12 activates the pneumatic drive mechanism, solenoid valve 19 opens, and high-pressure gas in pressure tank 17 enters the cavity 15 of upper punch 9 through main air pipe 18, branch pipe 22, second air passage 21 and first air passage 20. The air pressure pushes movable block 14 to move outward against the elastic force of first spring 16. Movable block 14 drives top block 13 to extend from the first through hole, pushing off any tablets that may be adhering to the end face of upper punch 9, so that upper punch 9 is completely separated from tablets. Then, solenoid valve 19 switches to depressurize, and first spring 16 pulls top block 13 and movable block 14 back to their original positions.

[0053] Step 4, Lower Punch Pushing: After the upper punch 9 is fully reset, the controller 12 controls the second cylinder 33 to continue driving the lower die base 8 upward. The lower punch 10 pushes the formed tablet in the die hole 41 upward to the top surface of the middle die 6. At the same time, the pneumatic drive mechanism is activated again, and compressed gas enters the cavity 15 in the lower punch 10 through the corresponding air passage, driving the push block 13 on the lower punch 10 to extend and push the tablet off the end face of the lower punch 10, ensuring that the tablet is completely detached from the lower punch 10 and placed flat on the top surface of the middle die 6. Then the push block 13 in the lower punch 10 resets, and the second cylinder 33 drives the lower die base 8 and the lower punch 10 downward back to the loading position.

[0054] Step 5, Tablet Pushing and Circulating Feeding: After the lower punch 10 resets, the controller 12 activates the third power mechanism, driving the material box 11 back to the starting position from the other side of the middle mold 6. During the return process, in the pushing mechanisms on both sides of the material box 11, the pushing plate 34, under the elastic force of the second spring 38, contacts the already pressed tablets on the top surface of the middle mold 6 before the material box 11, pushing the tablets forward to the edge of the middle mold 6. The tablets then fall into the guide groove 39 and slide along the guide groove 39 into the collection box 40, completing the tablet collection. At the same time, the material box 11 refills the die hole 41 with new powder during the return process, preparing for the next round of tableting cycle, thus realizing a fully automatic continuous cycle operation of feeding, scraping, tableting, demolding, ejecting, pushing, and collecting.

[0055] Throughout the process, the controller 12, as the core control unit, precisely controls the coordinated actions of the first cylinder 32, the second cylinder 33, the motor 23, and the solenoid valve 19 according to the preset timing sequence, ensuring smooth connection of each step and realizing the automated production of pharmaceutical fungal extract tablets with high efficiency, stability, and anti-sticking properties.
