Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical tableting technology, and in particular to a rotary pharmaceutical tableting machine. Background Technology

[0002] A rotary pharmaceutical tablet press is a widely used piece of equipment in the pharmaceutical industry, mainly used to compress powder or granular materials into tablets. Its working principle is to achieve the tableting process through rotating pressure rollers and molds.

[0003] When using a rotary pharmaceutical tablet press, the material (such as powder) is first fed into the tablet press mold through the hopper. The rotating part of the tablet press usually consists of multiple pressure rollers and upper and lower molds. The material is compressed in the mold to form tablets. During rotation, the pressure rollers apply pressure evenly to the material in the mold, causing it to form a compact tablet. After compression, the tablet is lifted by springs inside the mold. Then, the tablet is conveyed out by the rotation of the mold and can be further processed such as sorting and packaging.

[0004] Although rotary tablet presses can compress pharmaceutical powder, they cannot deliver the powder in a precise quantity, resulting in uneven powder distribution in each mold cavity. This affects the weight and drug content of the tablets, thereby reducing production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rotary pharmaceutical tablet press, which aims to improve the problem in the prior art that the powder cannot be quantitatively conveyed, resulting in uneven powder content in each mold cavity, which in turn affects the weight and drug content of the tablets, thereby reducing production efficiency.

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

[0007] A rotary pharmaceutical tablet press includes an operating table, a horizontal plate fixedly connected to the upper part of the operating table, a quantitative feeding component arranged on the left side inside the horizontal plate, a rotary pressing component arranged in the middle of the horizontal plate, and a collecting component arranged at the lower part of the operating table.

[0008] The quantitative feeding assembly includes a storage bin, which is fixedly connected to the inside left side of the horizontal plate. A connecting pipe is fixedly connected to the lower part of the storage bin, and a quantitative chamber is fixedly connected to the lower part of the connecting pipe. A motor is installed outside the quantitative chamber, and a quantitative roller is fixedly connected to the output end of the motor. Quantitative grooves are evenly opened on the circumference of the quantitative roller. The quantitative roller is rotatably connected to the inside of the quantitative chamber, and a discharge pipe is fixedly connected to the lower part of the quantitative chamber.

[0009] Furthermore, the collection assembly includes a collection box, which is fixedly connected to the lower part of the operating table. A drawer is slidably connected inside the collection box. A mounting shell is fixedly connected to the outside of the collection box. A fan is installed inside the mounting shell. A filter screen is installed inside the mounting shell. A conveying pipe is fixedly connected to the upper part of the collection box. A collection cover is fixedly connected to the top of the conveying pipe.

[0010] Furthermore, the rotary pressing assembly includes a second motor, which is fixedly connected to the middle of the horizontal plate. A rotating rod is fixedly connected to the output end of the second motor. A first rotating disk is fixedly connected to the outside of the rotating rod. A second rotating disk is installed below the first rotating disk. A fixed shell is evenly fixedly connected to the first rotating disk in a circular pattern. A pressing rod is slidably connected inside the fixed shell. A first spring is sleeved on the outside of the pressing rod. A pressing groove is evenly opened in a circular pattern on the upper part of the second rotating disk. A second spring is fixedly connected inside each of the multiple pressing grooves. A top plate is fixedly connected to the top of the second spring. A turntable is installed on the lower right side of the horizontal plate.

[0011] Furthermore, an installation ring is fixedly connected to the outside of the quantitative chamber, and the motor is fixedly connected inside the installation ring.

[0012] Furthermore, a feed inlet is fixedly connected to the upper part of the storage tank.

[0013] Furthermore, a baffle is installed on the upper part of the operating table, and a feeding plate is fixedly connected to the outside of the baffle.

[0014] Furthermore, fixing rods are fixedly connected to both sides of the lower part of the collection cover, and the bottoms of the two fixing rods are fixedly connected to the upper sides of the operating table.

[0015] Furthermore, a display panel is fixedly connected to the outer right side of the horizontal plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, during feeding, the material enters the storage tank through the feed inlet, enters the metering bin by gravity, and falls into the metering groove of the metering roller. The motor is started to drive the metering roller to rotate, and the material in the metering groove rotates accordingly. When the metering groove rotates to the discharge pipe position, the material falls into the discharge pipe under the action of gravity and is transported to the pressing groove on the rotating disk II through the discharge pipe, realizing quantitative addition and ensuring that the amount of powder in each mold cavity is consistent, thereby ensuring consistent tablet quality and improving work efficiency.

[0018] 2. In this utility model, during pressing, the blower is started to collect the powder through the collection hood and convey it to the collection box through the conveying pipe. When the powder is taken out, the drawer is simply taken out of the collection box. Installing a filter screen can filter the powder, prevent the blower from sucking it in, extend its service life, reduce powder waste, ensure full utilization of materials, and thus reduce production costs.

Detailed Implementation

[0028] 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.

[0029] Reference Figure 1 , Figure 3 and Figure 6 This utility model provides an embodiment of a rotary pharmaceutical tablet press, including an operating table 1. A horizontal plate 2 is fixedly connected to the upper part of the operating table 1. A quantitative feeding component is provided on the left side inside the horizontal plate 2 to facilitate the quantitative addition of materials. A rotary pressing component is provided in the middle of the horizontal plate 2 to facilitate the pressing of powder. A collecting component is provided at the lower part of the operating table 1 to facilitate the collection of powder generated during pressing. A baffle 28 is installed on the upper part of the operating table 1. A feeding plate 27 is fixedly connected to the outside of the baffle 28 to facilitate the collection and feeding of the pressed tablets. A display panel 30 is fixedly connected to the right side outside the horizontal plate 2, and the working status of the tablet press can be displayed on the display panel 30 in real time.

[0030] The quantitative feeding assembly includes a storage bin 3, which is fixedly connected to the inside left side of the horizontal plate 2. A connecting pipe 5 is fixedly connected to the lower part of the storage bin 3, and a quantitative chamber 6 is fixedly connected to the lower part of the connecting pipe 5. A motor 8 is installed outside the quantitative chamber 6, and a quantitative roller 9 is fixedly connected to the output end of the motor 8. Quantitative grooves are evenly opened on the circumference of the quantitative roller 9. The quantitative grooves ensure the quantitative addition of materials. The quantitative roller 9 is rotatably connected inside the quantitative chamber 6. A discharge pipe 10 is fixedly connected to the lower part of the quantitative chamber 6 to facilitate the discharge of materials. An installation ring 7 is fixedly connected to the outside of the quantitative chamber 6, and the motor 8 is fixedly connected inside the installation ring 7 to facilitate the fixation of the motor 8. A feed inlet 4 is fixedly connected to the upper part of the storage bin 3 to facilitate the addition of materials.

[0031] Specifically, in the pharmaceutical tableting process, firstly, the material is poured into the storage tank 3 through the feed inlet 4. The storage tank 3 provides a temporary storage space for the material and guides it smoothly to the downstream metering hopper 6 by gravity. After entering the metering hopper 6, the material flows steadily into the metering trough under the action of gravity. Next, the motor 8 is started, which drives the metering roller 9 to rotate. The rotation of the metering roller 9 causes the material inside the metering trough to rotate. At this time, the material in the metering trough is subjected to a uniform rotational force, which makes the material fully distributed in the trough and maintains the consistency of the amount of material in each metering trough. When the metering trough containing the material rotates to the position of the discharge pipe 10, the material inside the metering trough will enter the discharge pipe 10 under the action of gravity. Finally, the material enters the pressing trough opened on the upper part of the rotating disk 21 through the discharge pipe 10. The metered addition ensures that the amount of powder in each mold cavity is completely consistent, so that the weight, appearance, density and drug content of each tablet can be kept highly consistent, which significantly improves the production efficiency in the tableting process.

[0032] Reference Figure 2 and Figure 5 The collection assembly includes a collection box 11, which is fixedly connected to the lower part of the operating table 1. A drawer 12 is slidably connected inside the collection box 11. A mounting shell 13 is fixedly connected to the outside of the collection box 11. A fan 14 is installed inside the mounting shell 13. A filter screen 15 is installed inside the mounting shell 13. The filter screen 15 facilitates the filtration of the collected powder. A conveying pipe 16 is fixedly connected to the upper part of the collection box 11. A collection cover 17 is fixedly connected to the top of the conveying pipe 16. The collection cover 17 facilitates the collection of the powder generated by pressing. Fixing rods 18 are fixedly connected to both sides of the lower part of the collection cover 17. The bottom of the two fixing rods 18 is fixedly connected to the upper sides of the operating table 1. The fixing rods 18 facilitate the fixation of the collection cover 17.

[0033] Specifically, during the tableting process, the blower 14 is activated. The blower 14 draws in the generated powder through powerful suction. Subsequently, the powder is conveyed to the inside of the collection box 11 via the conveying pipe 16. The conveying pipe 16 efficiently transports the collected powder to the collection box 11, which can hold a large amount of powder, providing space for subsequent reuse. When removing the collected powder, the operator can easily retrieve it by simply removing the drawer 12 from inside the collection box 11. Through effective powder collection and filtration, the collected powder can be reused. This step significantly reduces waste in the production process, ensuring that every part of the material is fully utilized, thereby avoiding waste of raw materials and increased production costs, thus reducing production costs.

[0034] Reference Figure 4 and Figure 7The rotary pressing assembly includes a second motor 31, which is fixedly connected to the middle of the horizontal plate 2. A rotating rod 19 is fixedly connected to the output end of the second motor 31. A rotating disk 20 is fixedly connected to the outside of the rotating rod 19. A second rotating disk 21 is installed at the bottom of the first rotating disk 20. A fixed shell 22 is evenly fixedly connected to the first rotating disk 20 in a circular pattern. A pressing rod 23 is slidably connected inside the fixed shell 22. The pressing rod 23 facilitates the pressing operation of the tablets. A spring 24 is sleeved on the outside of the pressing rod 23. A pressing groove is evenly opened in a circular pattern on the upper part of the second rotating disk 21. The pressing groove facilitates the storage of materials. A spring 25 is fixedly connected inside each of the multiple pressing grooves. A top plate 26 is fixedly connected to the top of the spring 25. A turntable 29 is installed on the lower right side of the horizontal plate 2.

[0035] Specifically, during pressing, motor 231 is started, which drives the rotating rod 19 fixed at its output end to rotate. The rotation of the rotating rod 19 causes the externally fixed rotating disk 1320 and rotating disk 21 to rotate synchronously. When rotating disk 1320 and rotating disk 21 rotate, rotating disk 1320 causes the internally fixed housing 22 to rotate. The rotation of housing 22 causes the internally slidably connected pressing rod 23 to move. When the pressing rod 23 moves to the lower part of the rotating disk 29, the rotating disk 29 squeezes the pressing rod 23. After being subjected to force, the pressing rod 23 moves downward and deforms the externally sleeved spring 24. When the pressing rod 23 moves downward, it presses the material inside the pressing groove of the rotating disk 21 into shape. During pressing, the top plate 26 is subjected to force, causing the lower fixed spring 25 to deform. When the pressing rod 23 disengages from the rotating disk 29, the pressing rod 23 moves out of the pressing groove under the reaction force of the spring 1 24. At the same time, under the reaction force of the spring 25, the top plate 26 pushes out the tablets pressed inside the pressing groove. Then, when the tablets move to the position of the baffle 28, they will be discharged through the feeding plate 27 under the action of the baffle 28, thus completing the tablet pressing operation.

[0036] Working principle: During feeding, the material is first poured into the storage tank 3 through the feed inlet 4. Under the action of gravity, the material inside the storage tank 3 falls into the metering chamber 6. The material falling into the metering chamber 6 will fall into the metering groove opened inside the metering roller 9. Then, the motor 8 is started. The motor 8 drives the metering roller 9, which is fixed at the output end, to rotate. The rotation of the metering roller 9 drives the material in the metering groove to rotate. When the metering groove containing the material rotates to the position of the discharge pipe 10, the material in the metering groove falls into the discharge pipe 10 under the action of gravity. Finally, it is transported through the discharge pipe 10 to the pressing groove opened on the upper part of the rotating disc 21. This realizes the quantitative addition of materials during pharmaceutical tableting, ensuring that the amount of powder in each mold cavity is consistent, so that the weight, appearance, density and drug content of each tablet are consistent, thus improving the working efficiency of the equipment.

[0037] During compression, the powder produced by compression is collected by the collection hood 17 by starting the blower 14, and then transported to the inside of the collection box 11 through the conveying pipe 16. When removing the powder, the drawer 12 is removed from the inside of the collection box 11. The filter screen 15 installed inside the mounting shell 13 can filter the collected powder, prevent the blower 14 from sucking it in, and extend the service life of the blower 14. This makes it easy to collect the powder produced during pharmaceutical tablet compression, reduces powder waste, and allows the collected powder to be reused, ensuring that every part of the material is fully utilized, thereby reducing production costs.

[0038] 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.
