Description

Technical Field

[0001] The present invention belongs to the technical field of pharmaceutical equipment, and in particular relates to an intelligent tablet press. Background Art

[0002] With the continuous development of the pharmaceutical machinery industry, people have higher and higher requirements for tablet presses. At present, the development of tablet press technology is moving towards the direction of intelligence, flexibility, precision and meeting GMP requirements. New technologies of products are continuously improved, the reliability and stability of equipment are gradually enhanced, the overall intelligence of products is improved, the working intensity of operators is reduced, and reducing the result deviation caused by the operation of operators at different levels has become a new pursuit.

[0003] The tablet presses used at the present stage adopt traditional transmission methods. When the equipment runs for a long time, the temperature rises, which easily leads to changes in the wear degree of the equipment, thus affecting the stability of temperature-sensitive medicinal powders. Long-term lubrication of the equipment is likely to cause the accumulation of waste oil, resulting in the occurrence of oil splashing, thus affecting the appearance and quality of the finished products. When conducting routine inspections on the equipment, most inspections are carried out by manually selecting some inspection points. The selection of inspection points is not meticulous enough, which is likely to cause inestimable losses caused by some points not being inspected in place, and cannot be monitored in real time. For the wear state of some components of the equipment, they cannot be found and replaced in time, resulting in production stagnation. Summary of the Invention

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0043] The following further describes the embodiments of the present invention with reference to the accompanying drawings:

[0044] As Figure 1 、 Figure 2 shown, an intelligent tablet press includes a frame body. A bottom plate 11 is provided at the bottom of the frame body. An upright frame 10 is provided on the bottom plate 11. A main shaft 6 is provided at the center of the upright frame 10. A torque motor 9 is placed inside the upright frame 10. The torque motor 9 is installed on the main shaft 6. A base 7 is provided at the upper part of the upright frame 10. The base 7 is installed on the main shaft 6. One end of a column 5 is connected to the periphery of the upright frame 10 through a pull rod 8, and the other end of the column 5 is connected to a top plate 1. The top plate 1 is placed above the tablet pressing chamber 2. Preferably, the pull rod 8 includes multiple ones, and the multiple pull rods 8 are fixed to the upright frame 10 through nuts 12. Based on the original structure, this embodiment adjusts the way of stress-bearing parts, makes the base 7 and the upright frame 10 participate in the equipment stress at the same time, adds the pull rod 8, reduces the deformation of the equipment caused by work, increases the thickness of the top plate 1 and the layout position of the rib plates, changes the structural form of the upper pressing wheel, changes the stress points of the upper and lower pressing wheels to reduce vibration factors, and overcomes the problem of serious noise pollution of the existing equipment.

[0045] As Figure 3As shown, the torque motor 9 is respectively connected to the water chiller 13 through the first water inlet pipe 14 and the first water outlet pipe 15, changing the original two-stage deceleration method, that is, through the first-stage deceleration of the three-phase asynchronous motor pulley and the second-stage deceleration of the worm and worm gear. When the above pulley runs, it is easy to generate noise pollution, and the transmission efficiency of the worm and worm gear is low. Long-term operation causes the temperature to rise, which is transmitted to the tablet pressing chamber 2 and affects the physical or chemical property changes of the heat-sensitive raw materials. After replacing the torque motor 9, the temperature is lowered by the water chiller 13, and the temperature is adjusted according to the usage requirements to avoid the temperature being too high and being conducted to the tablet pressing chamber 2.

[0046] As Figure 1 shown, a tablet pressing chamber 2 is provided at the top of the main shaft 6. A monitoring device and a temperature lowering device are provided in the tablet pressing chamber 2. The monitoring device and the temperature lowering device are respectively connected to a processor, and the processor is connected to an alarm device.

[0047] Specifically, as Figure 1 、 Figure 4 shown, the tablet pressing chamber 2 successively includes an upper punch plate 19, a middle punch plate 20 and a lower punch plate 21 from top to bottom. The upper punch plate 19 is installed on the main shaft 6, and the middle punch plate 20 and the lower punch plate 21 are respectively installed on the upper punch plate 19. Upper punches 3 are annularly distributed at the edge of the upper punch plate 19, lower punches 4 are annularly distributed at the edge of the lower punch plate 21, and the upper punches 3 and the lower punches 4 are arranged oppositely. As Figure 5 、 Figure 6 shown, a guide rail 26 is provided at the bottom of the lower punch 4. The monitoring device includes sensors. There are multiple sensors, and the multiple sensors are evenly arranged on the guide rail 26. The multiple sensors are connected to a processor. Preferably, the sensors provided in this embodiment are temperature sensors 27. When the temperature sensors 27 detect that the temperature is too high, the processor drives the alarm device to issue an alarm. In this embodiment, the sensors sense the abnormal wear of the guide rail 26 and give early warning prompts. Through the early warning prompts, the detection response position is detected, and the abnormal monitoring and maintenance of the equipment operation state are completed. The wear state of the guide rail 26 is detected by the sensors, and an early warning is given when the guide rail 26 wears to a medium wear degree, and corresponding spare parts are prompted to be reserved. It improves the problems such as the increased jacking force caused by poor lubrication and the sluggish punching of the mold during the operation of the guide rail 26, resulting in increased wear and reduced service life of parts.

[0048] As Figure 4 shown, the temperature lowering device provided in this embodiment includes a water supply pipe 17, a water return pipe 18 and a diversion pipe 24. The diversion pipe 24 is arranged on the middle punch plate 20, and the diversion pipe 24 is respectively connected to the water chiller 13 through the water supply pipe 17 and the water return pipe 18. Preferably, a sealing ring 23 is installed inside the middle punch plate 20, a sealing ring pressing plate 22 is provided below the sealing ring 23, and the sealing ring pressing plate 22 and the middle punch plate 20 form a circulating cavity, and the diversion pipe 24 is placed in the circulating cavity.

[0049] As Figure 7As shown in the figure, the diversion pipe 24 includes a first shunt pipe 31, a second shunt pipe 29, a water inlet shunt pipe 25 and a water return shunt pipe 32. The first shunt pipe 31 and the second shunt pipe 29 are semi-circular with the same diameter. The water inlet shunt pipe 25 and the water return shunt pipe 32 are straight. One end of the water inlet shunt pipe 25 is communicated with one end of the shunt end cover 33. The other end of the water inlet shunt pipe 25 is connected to the first end of the water inlet three-way 28. One end of the water return shunt pipe 32 is communicated with the other end of the shunt end cover 33. The other end of the water return shunt pipe 32 is connected to the first end of the water return three-way 30. One end of the first shunt pipe 31 is connected to the second end of the water inlet three-way 28. The other end of the first shunt pipe 31 is connected to the second end of the water return three-way 30. One end of the second shunt pipe 29 is connected to the third end of the water inlet three-way 28. The other end of the second shunt pipe 29 is connected to the third end of the water return three-way 30. The first shunt pipe 31 and the second shunt pipe 29 are distributed in an annular shape. The water inlet shunt pipe 25 and the water return shunt pipe 32 are respectively placed on a straight line connecting the two ends of the annular shape. The water supply pipe 17 and the water return pipe 18 are vertically placed on the top of the shunt end cover 33. One end of the water supply pipe 17 and one end of the water return pipe 18 are respectively connected to the two ends of the shunt end cover 33. The other end of the water supply pipe 17 and the other end of the water return pipe 18 are respectively connected to the two ends of the rotary joint 16. The two ends of the rotary joint 16 are respectively connected to the water chiller 13 through the second water inlet pipe and the second water outlet pipe. Specifically, the cold water flows from the water chiller 13 through the second water inlet pipe and the water supply pipe 17 into the water inlet shunt pipe 25. After flowing through the water inlet three-way 28 into the first shunt pipe 31 and the second shunt pipe 29 respectively, it flows into the water return shunt pipe 32 through the water return three-way 30, and then flows into the water chiller 13 through the water return pipe 18 and the second water outlet pipe in sequence, realizing the temperature control of the middle punch plate 20.

[0050] The working principle of the embodiment of the present invention is as follows:

[0051] After the water chiller 13 works, the cold water is sent into the torque motor 9 through the first water inlet pipe 14, and after cooling it, it flows back to the water chiller 13 through the first water outlet pipe 15 to ensure the working temperature of the torque motor 9. Avoid the change of the equipment wear degree caused by the temperature rise during the long-term operation of the equipment.

[0052] After the water chiller 13 works, the cold water flows into the water inlet shunt pipe 25 through the second water inlet pipe and the water supply pipe 17. After flowing through the water inlet three-way 28 into the first shunt pipe 31 and the second shunt pipe 29 respectively, it flows into the water return shunt pipe 32 through the water return three-way 30, and then flows into the water chiller 13 through the water return pipe 18 and the second water outlet pipe in sequence, realizing the temperature control of the middle punch plate 20 and avoiding the change of the physical properties of the material caused by the too high temperature of the turntable.

[0053] A temperature sensor 27 is provided on the guide rail 26. When the temperature sensor 27 detects that the temperature of a certain place on the guide rail 26 is too high, the temperature sensor 27 sends a signal to the processor, and the processor drives the alarm device to give an alarm to remind the staff to repair and replace the guide rail 26.

[0054] The advantages and positive effects of the present invention are as follows:

[0055] 1. The present invention overcomes the existing transmission method, adopts a new type of motor, and changes the original two-stage deceleration method, that is, through the first-stage deceleration of the V-belt pulley of the three-phase asynchronous motor and the second-stage deceleration of the worm and worm gear. When the above-mentioned V-belt pulley runs, it is easy to generate noise pollution, the transmission efficiency of the worm and worm gear is low, and the temperature rises after long-term operation, which is transmitted to the tablet pressing chamber and affects the physical or chemical property changes of heat-sensitive raw materials. After replacing the torque motor, it is cooled by a water chiller, and the temperature is adjusted according to the usage requirements to avoid the temperature being too high and being conducted to the tablet pressing chamber.

[0056] 2. The present invention sets a circulating cavity on the middle punch plate, and connects the circulating cavity and the water chiller through the water inlet pipe and the water outlet pipe to avoid the temperature of the turntable being too high and causing changes in the physical properties of the material; the present invention overcomes the problem that it is difficult to export the heat generated by the friction between the traditional turntable and the material and the work done by the mold, and can control the temperature of the middle punch plate according to the characteristics of the material, with a wide application range and strong practicability.

[0057] 3. On the basis of the original structure, the present invention adjusts the way of stress-bearing parts, enables the base and the vertical frame to participate in the equipment stress at the same time, adds a pull rod, reduces the deformation of the equipment caused by work, increases the thickness of the top plate and the layout position of the rib plates, changes the structural form of the upper pressure wheel, and changes the stress points of the upper and lower pressure wheels to reduce the vibration factor, thus overcoming the problem of serious noise pollution of the existing equipment.

[0058] 4. The present invention uses sensors to sense abnormal wear of the guide rail and gives early warning prompts. Through the early warning prompts, the detection response position is detected to complete the abnormal monitoring and maintenance of the equipment operation status. The wear status of the guide rail is detected by sensors, and an early warning is given when the guide rail wears to a medium wear degree, prompting to reserve corresponding spare parts. It improves the problems such as increased jacking force caused by poor lubrication and stuttering punching of the mold during the operation of the guide rail, resulting in increased wear and reduced service life of parts.

[0059] 5. The present invention can adjust the tablet pressing speed of the tablet press according to key information such as the pressure of the tablet press, the temperature of the track, the current, and the tablet weight and appearance of the tablets, improve the production efficiency of the tablet press, and truly reflect the production information of a certain section, batch or multiple batches during the production process, which is convenient for identifying the batch differences of the tablets.
