Description

Technical Field

[0001] This utility model relates to the field of aluminum magnesium carbonate chewable tablet production technology, and in particular to a tablet press for producing aluminum magnesium carbonate chewable tablets. Background Technology

[0002] Magnesium aluminum carbonate chewable tablets are an over-the-counter antacid and gastric mucosa protectant. Its main ingredient is magnesium aluminum carbonate, chemically classified as basic magnesium aluminum carbonate, a layered crystalline structure of dihydroxy magnesium aluminum carbonate hydrate. The magnesium aluminum carbonate content in each tablet varies depending on the brand and dosage form, generally between 0.5 and 1.0 grams. This compound works in an acidic environment, neutralizing stomach acid and forming a protective film on the gastric mucosa.

[0003] In existing aluminum magnesium carbonate chewable tablet production equipment, after the stamping device is started, the aluminum magnesium carbonate particles in the hopper fall naturally under gravity and fill the mold cavity. The upper punch of the stamping device moves downward under the drive of the hydraulic system or mechanical transmission system to apply pressure to the particles and stamp the aluminum magnesium carbonate raw material into chewable tablets.

[0004] However, in the existing technology, after the aluminum magnesium carbonate chewable tablet production device is stamped, an additional drive source is needed to drive the feeding device to take the aluminum magnesium carbonate chewable tablet out of the device. The process is cumbersome and may lead to production incoordination and low production efficiency. Therefore, a tablet press for aluminum magnesium carbonate chewable tablet production is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tableting machine for producing aluminum magnesium carbonate chewable tablets, aiming to improve the problems of discontinuous production operations and low efficiency in the existing technology.

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

[0007] A tableting machine for producing magnesium aluminum carbonate chewable tablets includes a base plate, a support frame fixedly connected to the top of the base plate, a motor fixedly connected to one side of the support frame, a rotating shaft fixedly connected to the drive end of the motor, a turntable fixedly connected to the other end of the rotating shaft, a rotating bar rotatably connected to one side of the turntable, a lever rotatably connected to the bottom of the rotating bar, a top support plate fixedly connected to the top of the lever, and a feeding assembly for quantitative feeding provided at the rear of the support frame.

[0008] As a further description of the above technical solution:

[0009] The rotating bar is internally movably connected to one side of the support frame, the lever is externally rotatably connected to the inside of the base plate, and the top support plate is externally slidably connected to the inside of the base plate.

[0010] As a further description of the above technical solution:

[0011] A locking block is fixedly connected to the outside of the rotating shaft, and an eccentric wheel is provided on the outside of the rotating shaft. The outside of the locking block engages with the inside of the eccentric wheel. A sliding block is rotatably connected to the bottom of the eccentric wheel, and a stamping rod is fixedly connected to the bottom of the sliding block.

[0012] As a further description of the above technical solution:

[0013] The support frame is internally fixedly connected to a limiting plate, and the sliding block is externally slidably connected to the inside of the limiting plate.

[0014] As a further description of the above technical solution:

[0015] The sliding block is fixedly connected to a sliding plate on the outside, and two fixed plates are fixedly connected to the bottom of the sliding plate. Two rotating plates are rotatably connected to the bottom of the two fixed plates.

[0016] As a further description of the above technical solution:

[0017] The support frame is internally slidably connected to a pusher plate, and the rear sides of the two rotating plates are rotatably connected to the front side of the pusher plate.

[0018] As a further description of the above technical solution:

[0019] The feeding assembly includes a feeding box, the front side of which is fixedly connected to the rear side of the support frame. An electric push rod is fixedly connected inside the top support plate. A metering bucket is fixedly connected to the drive end of the electric push rod. A baffle is fixedly connected to one side of the metering bucket.

[0020] As a further description of the above technical solution:

[0021] A funnel is fixedly connected to the top of the feeding box, and a feeding hopper is fixedly connected to the bottom of the feeding box.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the motor drives the rotating shaft to rotate, which in turn drives the turntable to rotate, causing the rotating bar to move relative to each other, which in turn drives the lever to move, lifting the top support plate and pushing out the aluminum magnesium carbonate sheet that was previously stamped. Then, the two rotating plates rotate and pull the pusher plate to slide forward, pushing out the aluminum magnesium carbonate sheet, thus completing the automatic feeding operation. This connects multiple processes and improves production efficiency.

[0024] 2. In this utility model, the drive end of the electric push rod retracts, causing the metering bucket to slide and align with the feeding bucket. The metered amount of aluminum magnesium carbonate powder inside falls into the inside of the push plate through the feeding bucket. As the metering bucket slides, the baffle slides and blocks the funnel from continuing to fall, thus completing the metered feeding operation. This greatly reduces product quality fluctuations caused by dosage errors and improves the production quality of aluminum magnesium carbonate sheets. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of a tablet press for producing aluminum magnesium carbonate chewable tablets, comprising a base plate 1 made of high-strength, thick-walled carbon steel, finely forged and precision milled, forming a regular rectangular plate with a flat and smooth surface. Strict flatness checks ensure that the flatness error is controlled within a minimal range, providing a supporting foundation for numerous components above. A support frame 2 is fixedly connected to the top of the base plate 1. The support frame 2 is welded from steel and provides an installation foundation for the subsequent stamping structure. A motor 3 is fixedly connected to one side of the support frame 2, serving as the power source for the stamping and feeding structures. A rotating shaft 4, forged from high-quality alloy steel and finely ground and polished, possesses excellent smoothness, effectively reducing friction during rotation and significantly improving fatigue strength and wear resistance. A turntable 7 is fixedly connected to the other end of the rotating shaft 4. The turntable 7 is disc-shaped and amplifies the power range of the motor 3 by rotating. A rotating bar 13 is rotatably connected to one side of the turntable 7. One end of the rotating bar 13 moves in a circular motion under the rotation of the turntable 7, thereby driving the subsequent structure to move up and down to complete the unloading. A lever 14 is rotatably connected to the bottom of the rotating bar 13. The lever 14 is used to transmit power and change the direction of force, driving the subsequent structure to slide upward and push out the aluminum magnesium carbonate chewing tablet to complete the unloading. A [missing information - likely a component or material] is fixedly connected to the top of the lever 14. The top support plate 16 is a combination of a circular plate and a circular rod. It slides upward under the drive of the lever 14 to push out the aluminum magnesium carbonate sheet. The rear side of the support frame 2 is provided with a feeding component for quantitative feeding. The internal rotating bar 13 is movably connected to one side of the support frame 2 to provide a limit for the movement of the rotating bar 13. The external rotating part of the lever 14 is rotatably connected to the inside of the base plate 1 to provide a fulcrum for the movement of the lever 14. The external sliding part of the top support plate 16 is slidably connected to the inside of the base plate 1, and the aluminum magnesium carbonate sheet is pushed out by sliding the top support plate 16.

[0033] Reference Figures 1 to 2A locking block 6 is fixedly connected to the outside of the rotating shaft 4. The locking block 6 is cuboid in shape. An eccentric wheel 5 is set on the outside of the rotating shaft 4. The outside of the locking block 6 engages with the inside of the eccentric wheel 5. The eccentric wheel 5 is driven to make eccentric motion by the movement of the locking block 6, which pulls the subsequent stamping structure to slide up and down to stamp the tablet. A sliding block 9 is rotatably connected to the bottom of the eccentric wheel 5. The sliding block 9 is limited by the subsequent structure and slides up and down, thereby driving the stamping structure to move to stamp. A stamping rod 12 is fixedly connected to the bottom of the sliding block 9. The stamping rod 12 is cylindrical and made of food-grade stainless steel. It contacts and extrudes the aluminum magnesium carbonate raw material. A limit plate 8 is fixedly connected inside the support frame 2 to limit the sliding of the sliding block 9 so that it can only slide up and down. The outside of the sliding block 9 is slidably connected to the limit plate. Inside the support frame 8, a sliding plate 22 is fixedly connected to the outside of the sliding block 9. The sliding plate 22 is driven by the movement of the sliding block 9, thereby driving the subsequent structure to rotate and complete the pushing operation. Two fixed plates 10 are fixedly connected to the bottom of the sliding plate 22, and two rotating plates 11 are rotatably connected to the bottom of the two fixed plates 10. The rotating plates 11 are used to change the direction of the force, so that the force of vertical sliding becomes the pulling force of horizontal sliding. A push plate 15 is slidably connected inside the support frame 2. The push plate 15 is rectangular and has holes inside to receive the aluminum magnesium carbonate raw material put down by the feeding structure for the next stamping. The rear side of the two rotating plates 11 is rotatably connected to the front side of the push plate 15. The rotating plates 11 pull the push plate 15 to slide, pushing out the ejected aluminum magnesium carbonate sheet.

[0034] Reference Figure 4 The feeding assembly includes a feeding box 23, the front of which is fixedly connected to the rear of the support frame 2. The overall shape of the feeding box 23 resembles a regular rectangular box, and its outer shell is made of high-strength, corrosion-resistant stainless steel. An electric push rod 20 is fixedly connected inside the top support plate 16. The electric push rod 20 provides power for feeding the structure containing aluminum magnesium carbonate powder. A metering bucket 18 is fixedly connected to the drive end of the electric push rod 20. Its internal volume has been precisely calibrated and standardized. In accordance with different production needs, it can accurately measure a specific volume of aluminum magnesium carbonate raw material with the error controlled within a very small range, effectively ensuring the consistency of the dosage of each batch of tablet raw materials. A baffle 19 is fixedly connected to one side of the metering bucket 18. The baffle 19 can stop the material from falling when the metering bucket 18 moves, and accurately drop the aluminum magnesium carbonate raw material. A funnel 17 is fixedly connected to the top of the feeding box 23. The funnel 17 is shaped like a truncated cone with a larger opening at the top and a smaller opening at the bottom. The larger opening faces upward, which is designed to be wide and can easily pour in the material, reducing spillage and waste. The smaller opening faces downward, which can accurately connect to the metering bucket 18. A discharge bucket 21 is fixedly connected to the bottom of the feeding box 23. The discharge bucket 21 is used to guide the metered aluminum magnesium carbonate raw material into the interior of the pusher plate 15.

[0035] Working principle: First, the operator places magnesium aluminum carbonate powder inside the funnel 17, which falls into the metering container 18. Then, the drive end of the electric push rod 20 is activated to retract, causing the metering container 18 to slide and align with the feeding container 21. The metered amount of magnesium aluminum carbonate powder inside falls into the push plate 15 through the feeding container 21. As the metering container 18 slides, the baffle 19 slides to block the funnel 17 from continuing to fall, thus completing the metered feeding operation. This method can control the dosage of magnesium aluminum carbonate powder for each feeding with extreme precision, ensuring that the content of magnesium aluminum carbonate powder in each batch of medicine is exactly the same. This greatly reduces product quality fluctuations caused by dosage errors and improves the production quality of magnesium aluminum carbonate tablets.

[0036] Secondly, by turning on the switch of motor 3, the rotating shaft 4 is driven to rotate, which in turn drives the turntable 7 to rotate. The eccentric rotation of the turntable 7 drives the rotating bar 13 to move relative to each other, which in turn drives the lever 14 to move, lifting the top support plate 16 and ejecting the aluminum magnesium carbonate sheet from the previous stamping. At the same time, the rotation of the rotating shaft 4 drives the eccentric wheel 5 to rotate eccentrically, pulling the sliding block 9 upward to slide inside the limit plate 8, thereby driving the sliding plate 22 to slide upward, driving the two rotating plates 11 to rotate and pulling the pusher plate 15 to slide forward, pushing out the aluminum magnesium carbonate sheet, completing the automatic unloading operation. At the same time, the aluminum magnesium carbonate inside the pusher plate 15 continues to fall into the stamping hole for the next stamping operation. By providing the ejection of aluminum magnesium carbonate sheet during stamping and the subsequent pushing of aluminum magnesium carbonate sheet unloading, multiple processes are smoothly connected, improving production efficiency.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
