Description

Technical Field

[0001] This invention relates to the field of powder packaging technology, specifically to a packaging device for preparing artificial bezoar. Background Technology

[0002] Artificial bezoar is a traditional Chinese medicine. It is made from bovine bile powder, cholic acid, deoxycholic acid from pigs, taurine, bilirubin, cholesterol, trace elements, etc. It is a yellow, loose powder with the effects of clearing heat and detoxifying, resolving phlegm and calming convulsions. It is often used to treat symptoms such as delirium due to phlegm-heat, coma and aphasia, infantile convulsions, sore throat, mouth and tongue sores, carbuncles and boils.

[0003] In existing technologies, the packaging of artificial bezoar requires sealing it in plastic bags. For example, the artificial bezoar packaging bag proposed in Chinese patent document CN304868560S lacks an effective metering device on the plastic bag sealing machine during the sealing process, resulting in inconsistent bezoar packaging quality. To address this issue, Chinese patent document CN211543967U proposes an artificial bezoar packaging device. This device achieves the advantage of quantitative feeding and weighing by coordinating a weighing sensor, support mechanism, fixing plate, storage bin, cover plate, handle, inclined block, feeding pipe, electric valve, protection box, processor, touch screen display, and alarm mechanism. When weighing and packaging artificial bezoar, the material can be dispensed quantitatively, avoiding over- or under-dispensing. However, in actual use, this type of packaging device has many drawbacks. First, when batch sealing and packaging artificial bezoar, it is necessary to use a weighing sensor in conjunction with an electric valve for multiple intermittent weighing and opening / closing operations, which cannot achieve continuous metering and sealing packaging, thus hindering the mass production of artificial bezoar. In addition, after the artificial bezoar powder on the platform is weighed, it needs to be manually turned over and poured into the channel connected to the sealing bag, which is cumbersome and will delay the production efficiency of artificial bezoar. Therefore, this application discloses a packaging device for the preparation of artificial bezoar to meet the needs of efficient preparation of artificial bezoar. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a packaging device for the preparation of artificial bezoar, which has the following beneficial effects:

[0019] 1. The packaging device for preparing artificial bezoar involves pouring artificial bezoar powder into a hopper and simultaneously activating a motor. This causes the central rotating shaft to drive the loading ring and replenishing ring to rotate synchronously. The artificial bezoar powder in the hopper falls into the loading ring and is dispersed by multiple fan-shaped ramps within the loading ring before falling through corresponding discharge holes into multiple metering boxes below. Since this is the initial metering stage, the weight of artificial bezoar powder collected in a single metering box does not yet meet the predetermined requirement. Therefore, the tilted metering box, combined with the elastic support of corresponding thin springs, allows the powder in the replenishing ring to enter the corresponding metering box below through the replenishing holes. As the amount of powder in the metering box gradually increases, when the predetermined weight requirement is reached, the metering box rotates to a horizontal position around the corresponding eccentric shaft axis, thus releasing the powder through the traction rope. The traction action causes the baffle at the corresponding position to press down and seal the feeding hole, stopping the feeding. This allows multiple metering boxes to rotate synchronously and continuously discharge material while the outer feeding ring supplements the metering. When the metering box rotates to the discharge position, the attraction of the metal block by the sector magnet causes the corresponding discharge bottom plate to flip open, thus pouring the artificial bezoar powder that has reached the predetermined weight into the connecting pipe and conveying it to the input end of the plastic pad sealing machine. Then, the bagging and sealing operation is completed. At the same time, the rolling of the ball bearings in the first ball seat on the sector magnet can improve the stability of the metering box when it rotates around the central axis and is affected by magnetic traction. In this way, the continuous metering and packaging operation of artificial bezoar can be completed without stopping the machine and continuously discharging material, thus improving the packaging efficiency of artificial bezoar.

[0020] 2. The packaging device for artificial bezoar preparation, by creating a chamfer, allows the powder in the discharge funnel to enter the carrying ring or replenishing ring, preventing accumulation at the top. Furthermore, by placing the discharge funnel close to the carrying ring, most of the bezoar powder falls into the carrying ring, facilitating rapid pre-filling of multiple metering boxes and shortening the overall metering time. As the metering box rotates under weight and the baffle is pulled downwards by the traction rope, the distance between the baffle and the replenishing hole gradually decreases, controlling the speed at which bezoar powder is added to the metering box. Combined with the slow rotation of the metering box, precise filling is achieved, improving metering accuracy. The hollow ramp, used in conjunction with the upper guide pipe, guides the powder falling into the metering box, causing it to fall to the side, promoting metering box deflection and improving metering accuracy. It also reduces the overall weight of the metering box, further enhancing the accuracy of the device at the metering level when used with lighter powdery materials.

[0021] 3. In this packaging device for artificial bezoar preparation, as the weight of bezoar powder in a single metering box is gradually increased using a feeding ring, the eccentric setting of the eccentric shaft and the metering box causes the metering box to flip. Simultaneously, a tension spring pulls one end of an arc-shaped rocker arm upwards. Utilizing the lever principle, the arc-shaped rocker arm rotates around its fulcrum on the corresponding connecting seat, while the other end presses down on the corresponding fan-shaped rocker plate. Compared to directly using a tension spring to pull the metering box, the arc-shaped rocker arm method allows for… The lighter bezoar powder makes it easier to control the angle of the metering box's rotation. At the same time, by utilizing the limiting block's restraining effect, when the corresponding metering box is located on the discharge hole for unloading, the attraction force of the fan-shaped magnet pulls the discharge base plate to deflect. The limiting block then abuts against the corresponding arc-shaped spring, and the metering box remains fixed under the "traction" of the arc-shaped spring and the arc-shaped rocker arm. This not only achieves stable unloading but also avoids the phenomenon of "accidental material falling" caused by the baffle loosening due to the accidental rotation of the metering box, thus improving the stability of the entire packaging device during operation.

[0022] 4. The packaging device for artificial bezoar preparation uses a snap-fit ​​installation method, which allows the loading ring to be easily removed from the central rotating shaft. By rotating the threaded tube, the height of the central plate can be adjusted. This allows the use of an arc-shaped spring, a fan-shaped seesaw, and an arc-shaped rocker arm, in conjunction with a tension spring, to change the initial tilt angle of the measuring box. This adjusts the loading capacity of the measuring box to a horizontal state, thereby achieving the measurement of bezoar packaging weights under different requirements and improving the practicality of the entire device. By setting a reduction hole, the fan-shaped seesaw can rotate unidirectionally in its natural state in conjunction with the arc-shaped spring, preventing the end of the fan-shaped seesaw near the central rotating shaft from deflecting downwards undesirably, thus improving the stability of the device when changing the measuring range of the measuring box.

[0039] 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.

[0040] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a packaging device for the preparation of artificial bezoar.

[0041] In one typical implementation of this application, such as Figures 1-15As shown, a packaging device for preparing artificial bezoar includes a hopper 2 and a plastic bag sealing machine mounted on a support 1, and a metering component mounted between the support 1 and the hopper 2. The metering component works with the hopper 2 to divide the artificial bezoar into multiple uniform portions. The metering component includes inner and outer nested material-carrying rings 3 and replenishing rings 4, and multiple metering boxes 8 mounted on a turntable 36. The bottom of the hopper 2 is provided with a discharge funnel 5 corresponding to the positions of the material-carrying rings 3 and replenishing rings 4. A motor 6 for driving the metering component to rotate is also mounted on the support 1. The metering boxes 8 are rotatably mounted on corresponding rotating drums 18 via eccentric shafts 17. The rotating drums 18 are connected to the material-carrying rings 3. The eccentric shafts 17 are mounted on one side of the corresponding metering box 8, and tension springs 19 are also connected to the metering boxes 8. The bottom end is also provided with a matching feeding hole 23 and a baffle 27. The baffle 27 is mounted on the connecting ring 22 by a thin spring 24, and a traction rope 26 is also connected between the baffle 27 and the corresponding metering box 8. After the metering box 8 is fed by the material loading ring 3, it tilts and the feeding hole 23 opens simultaneously. The turntable 36 is also provided with a discharge assembly for conveying multiple portions of artificial bezoar powder to the input end of the plastic bag sealing machine. The discharge assembly includes a metal block 30 and a fan-shaped magnet 32. The metal block 30 is mounted on the corresponding discharge base plate 29. The discharge base plate 29 is mounted on the bottom end of the corresponding metering box 8 by a hinge 28 with a torsion spring. The discharge assembly also includes a connected discharge hole 33 and a connecting pipe 34. The turntable 36 is also provided with an amplification assembly for controlling the deflection of the metering box 8. The amplification component includes an arc-shaped rocker arm 44 connected at one end to a corresponding tension spring 19, and multiple fan-shaped rockers 38 rotatably mounted on a central disk 15. An arc-shaped spring piece 41 is also mounted on the central disk 15 to limit the rotation of the fan-shaped rockers 38. The arc-shaped spring piece 41 is also equipped with a limiting block 42 to limit its own deformation. One end of the arc-shaped rocker arm 44 abuts against the corresponding fan-shaped rocker arm 38, and the end of the arc-shaped rocker arm 44 near the central disk 15 is rotatably mounted at the bottom of the material-carrying ring 3. When it is necessary to package the powdered artificial bezoar in plastic bags, the artificial bezoar powder is poured into the hopper 2, and the motor 6 is turned on simultaneously, causing the metering component to rotate synchronously with the continuous feeding of powder. This causes the artificial bezoar powder in the hopper 2 to fall into the material-carrying ring 3 and pass through the material-carrying ring. 3. After dispersion processing, the powder falls into multiple metering boxes 8 below. Since this is the initial metering stage, the weight of artificial bezoar powder collected in a single metering box 8 has not yet reached the predetermined requirement. Therefore, through the tilted metering box 8 and the elastic support of the corresponding thin spring 24, the powder in the feeding ring 4 enters the corresponding metering box 8 below through the feeding hole 23. As the amount of powder in the metering box 8 gradually increases, when the predetermined weight requirement is reached, the metering box 8 flips to a horizontal position. Then, through the traction of the traction rope 26, the baffle 27 at the corresponding position presses down and seals the feeding hole 23, stopping the feeding. This achieves simultaneous synchronous rotation and continuous feeding of multiple metering boxes 8, while the outer feeding ring 4 supplements the metering. When the metering box 8 rotates to the discharge position...By utilizing the attraction of the sector magnet 32 ​​to the metal block 30, the corresponding discharge base plate 29 is flipped open, allowing the artificial bezoar powder of the predetermined weight to be poured into the connecting pipe 34 and conveyed to the input end of the plastic pad sealing machine. The bagging and sealing operation is then completed. This allows for continuous metering and packaging of artificial bezoar without stopping the machine, improving packaging efficiency. Furthermore, as the weight of the bezoar powder in a single metering box 8 is gradually increased using the replenishing ring 4, the eccentric setting of the eccentric shaft 17 and the metering box 8 causes the metering box 8 to flip, simultaneously pulling one end of the arc-shaped rocker arm 44 upwards via the tension spring 19, thus utilizing the lever principle of the arc-shaped rocker arm 44. This causes the other end of the arc-shaped rocker arm 44 to press down on the corresponding fan-shaped rocker arm 38. Compared to directly using the tension spring 19 to pull the metering box 8 to deflect, the arc-shaped rocker arm 44 makes it easier to control the angle at which the metering box 8 flips when handling lighter bezoar powder. Simultaneously, the limiting block 42 ensures that when the metering box 8 is unloading from the discharge hole 33, the attraction force of the fan-shaped magnet 32 ​​pulls the discharge base plate 29 to deflect. The metering box 8 remains fixed under the "traction" of the arc-shaped spring 41 and the arc-shaped rocker arm 44, achieving stable unloading and preventing accidental material drop due to the baffle 27 loosening caused by the accidental rotation of the metering box 8. This ensures stable operation of the entire packaging device.

[0042] As a preferred embodiment of this example, please refer to the appendix. Figures 1-4 The output end of motor 6 is connected to a reduction gearbox, and the output end of the reduction gearbox is connected to a central rotating shaft 7. Turntable 36 is fixedly installed on the top of the reduction gearbox. A tray 9 is fitted onto the top of the central rotating shaft 7. A material-carrying ring 3 is coaxially arranged with the central rotating shaft 7 and slidably engaged on the top of the central rotating shaft 7, with the material-carrying ring 3 located on the tray 9. A feeding chamber 21 for storing artificial bezoar powder is provided inside the feeding ring 4, and the upper inner diameter of the feeding ring 4 is larger than the lower inner diameter of the feeding ring 4. The feeding ring 4 is fitted around the outer periphery of the material-carrying ring 3 and is flush with the top of the material-carrying ring 3. The discharge funnel 5... The bottom is set with a fan-shaped flat opening, and the bottom of the discharge funnel 5 is located between the material carrying ring 3 and the material replenishing ring 4 and close to the inner wall of the material carrying ring 3. The top of the material carrying ring 3 and the material replenishing ring 4 are both provided with matching chamfers. By providing chamfers, the powder in the discharge funnel 5 can enter the material carrying ring 3 or the material replenishing ring 4, avoiding accumulation at the top. In addition, by placing the discharge funnel 5 close to the material carrying ring 3, most of the bezoar powder can fall into the material carrying ring 3, completing the subsequent rapid pre-filling of multiple metering boxes 8, thereby shortening the overall metering time of the metering box 8.

[0043] As a preferred embodiment of this example, please refer to the appendix. Figures 2-8 , Figures 10-15The bottom end of the material carrier ring 3 is provided with multiple evenly distributed discharge holes 11, which are located directly above the corresponding metering box 8. Multiple fan-shaped ramps 10 are also installed inside the material carrier ring 3. Each fan-shaped ramp 10 has a double slope, and the slope of adjacent fan-shaped ramps 10 corresponds to the position of the discharge hole 11. A guide pipe 12 connects the discharge hole 11 to the corresponding metering box 8. The top end of the guide pipe 12 matches the discharge hole 11, and the bottom end of the guide pipe 12 is set with a fan-shaped extension hole that fits the corresponding metering box 8. By setting the guide pipe 12 with an arc-shaped bottom end, the powder can be evenly dispersed in the metering box 8. Two end ears 16 are installed on one side of the metering box 8, and the two ends of the eccentric shaft 17 are respectively connected to... On the corresponding end ear 16, the rotating drum 18 is bolted to the inner wall of the bottom end of the material carrying ring 3. The eccentric shaft 17 is rotatably sleeved in the corresponding rotating drum 18. An extension plate is also provided on one side of the metering box 8. One end of the tension spring 19 is hung on the corresponding extension plate. A hollow slope 20 that fits against its side wall is also installed inside the metering box 8. By setting the hollow slope 20, in conjunction with the upper guide pipe 12, the powder falling into the metering box 8 is guided to the side, promoting the deflection of the metering box 8 and improving the metering accuracy. It can also reduce the overall weight of the metering box 8. When used with lighter powdery materials, it can further improve the accuracy of the device in terms of metering. The connecting ring 22 is sleeved on the bottom end of the feeding chamber 21. The feeding hole 23 is opened on the connecting ring 22. The bottom of the baffle 27 is connected to a vertical guide rod that is slidably sleeved on the connecting ring 22. The bottom of the connecting ring 22 is also connected to a guide cylinder 25. One end of the traction rope 26 is connected to the bottom end of the corresponding vertical guide rod, and the other end of the traction rope 26 passes through the corresponding guide cylinder 25 and is connected to the inner wall of the corresponding metering box 8. The bottom inner wall of the feeding chamber 21 is provided with an annular ridge 37 that matches the baffle 27. The discharge bottom plate 29 is hinged to the bottom of the corresponding metering box 8 and matches the position of the corresponding hollow slope 20. The metal block 30 is installed at the bottom of the corresponding metering box 8. The cross-sections of the fan-shaped magnet 32 ​​and the metal block 30 are both arc surfaces and match the rotation angle of the corresponding discharge bottom plate 29. In this application, magnets with opposite magnetic poles that attract each other can also be used instead of the metal block 30. The metal block 30 is connected to a sector magnet 32, and the bottom of the metal block 30 is also connected to a first ball seat 31. The first ball seat 31 is equipped with a ball bearing. The discharge hole 33 is opened on the turntable 36 and corresponds to the position of multiple discharge base plates 29. The discharge hole 33 is close to the discharge funnel 5. The top of the connecting pipe 34 is wide and located directly below the discharge hole 33. The other end of the connecting pipe 34 is connected to the input end of the plastic bag sealing machine. When it is necessary to continuously seal powdered artificial bezoar in plastic bags, the artificial bezoar powder is poured into the hopper 2, and the motor 6 is turned on at the same time. This causes the central rotating shaft 7 to drive the material carrying ring 3 and the replenishing ring 4 on it to rotate synchronously. This causes the artificial bezoar powder in the hopper 2 to fall into the material carrying ring 3 and be dispersed by multiple sector slides 10 in the material carrying ring 3.The material falls from the corresponding discharge hole 11 into multiple metering boxes 8 below. Since this is the initial metering stage, the weight of the artificial bezoar powder collected in a single metering box 8 has not yet reached the predetermined requirement. Therefore, through the tilted metering box 8 and the elastic support of the corresponding thin spring 24, the powder in the feeding ring 4 enters the corresponding metering box 8 below through the feeding hole 23. As the amount of powder in the metering box 8 gradually increases, when the predetermined weight requirement is reached, the metering box 8 rotates to a horizontal position around the axis of the corresponding eccentric shaft 17. Thus, through the traction of the traction rope 26, the baffle 27 at the corresponding position is pressed down and seals the feeding hole 23, stopping the feeding. This achieves simultaneous synchronous rotation and continuous feeding of multiple metering boxes 8, while the outer feeding ring 4 supplements the metering. When the metering box 8 rotates to the discharge position, the fan-shaped magnet 32 ​​is used to press the metal block 30. The adsorption effect causes the corresponding discharge bottom plate 29 to flip and open, thus pouring the artificial bezoar powder of the predetermined weight into the connecting pipe 34 and conveying it to the input end of the plastic pad sealing machine, where it is then bagged and sealed. Simultaneously, the rolling of the ball bearings in the first ball seat 31 on the sector magnet 32 ​​improves the stability of the metering box 8 when it rotates around the central axis 7 and is affected by magnetic traction. This allows for continuous metering and packaging of artificial bezoar without stopping the machine, improving packaging efficiency. Furthermore, as the metering box 8 flips under weight and the baffle 27 is pulled down by the traction rope 26, the distance between the baffle 27 and the feeding hole 23 gradually decreases, controlling the speed at which bezoar powder is added to the metering box 8. Combined with the slow rotation of the metering box 8, this achieves precise feeding and improves metering accuracy.

[0044] As a preferred embodiment of this example, please refer to the appendix. Figure 15 A material-gathering plate 35 is also installed on the edge of the turntable 36. The material-gathering plate 35 is positioned corresponding to the discharge hole 33, and the edges of the discharge hole 33 are rounded. By setting the material-gathering plate 35, the falling artificial bezoar can be guided, effectively preventing dust from overflowing. At the same time, by setting the rounded corners, the falling bezoar powder can enter the corresponding discharge hole 33 to a greater extent to complete the dropping and achieve accurate measurement.

[0045] As a preferred embodiment of this example, please refer to the appendix. Figures 7-11The inner wall of the central disc 15 is slidably secured to the central rotating shaft 7 via multiple guide blocks 14. A threaded tube 13 is threadedly connected to the central rotating shaft 7. The central disc 15 is located on top of the threaded tube 13. Multiple evenly distributed fan-shaped grooves are also formed on the central disc 15. The sidewalls of the fan-shaped rocker 38 are rotatably mounted on the corresponding fan-shaped groove sidewalls via a flip shaft 39. Multiple sets of connecting seats 43 are installed at the bottom of the hopper 2. One end of the arc-shaped rocker 44 is rotatably mounted on the corresponding connecting seat 43. One end of the arc-shaped rocker 44 is connected to a second ball seat 45. A ball bearing that abuts against the top of the corresponding fan-shaped rocker 38 is installed inside the second ball seat 45. One side of the arc-shaped spring 41 is secured to the central disc 15 via a snap-fit ​​mechanism. The piece 41 is located in the corresponding fan-shaped groove. The arc-shaped spring piece 41 is a thin, elastic metal sheet. The limiting block 42 is installed on the corresponding buckle and remains in contact with the corresponding arc-shaped spring piece 41 in its natural state. The end of the fan-shaped rocker 38 near the central rotating shaft 7 is also provided with a reduction hole 40. When the weight of the bezoar powder in a single metering box 8 is gradually increased by the feeding ring 4, due to the "eccentric" setting of the eccentric shaft 17 and the metering box 8, the metering box 8 flips over. At the same time, the tension spring 19 pulls one end of the arc-shaped rocker 44 upward. Thus, by utilizing the "lever principle" of the arc-shaped rocker 44, the arc-shaped rocker 44 rotates around its "fulcrum" on the corresponding connecting seat 43, and presses down the corresponding fan-shaped rocker 38 through the other end. Compared to The metering box 8 is deflected directly by the tension spring 19. The use of the arc-shaped rocker arm 44 makes it easier to control the angle at which the metering box 8 flips when handling lighter bezoar powder. Simultaneously, the limiting block 42 restricts the metering box 8 when it is unloading from the discharge hole 33. When the fan-shaped magnet 32 ​​pulls the discharge base plate 29 to deflect, the limiting block 42 abuts against the corresponding arc-shaped spring 41. The metering box 8 remains fixed under the "traction" of the arc-shaped spring 41 and the arc-shaped rocker arm 44, achieving stable unloading and preventing accidental material drop due to loosening of the baffle 27 caused by accidental rotation of the metering box 8. This improves the overall stability of the packaging device. Furthermore, the snap-fit ​​mechanism... The installation method allows the loading ring 3 to be easily removed from the central rotating shaft 7. By rotating the threaded tube 13, the height of the central plate 15 can be adjusted. This allows the initial tilt angle of the metering box 8 to be changed using the arc-shaped spring 41, the fan-shaped rocker 38, and the arc-shaped rocker arm 44, in conjunction with the tension spring 19. This adjusts the loading capacity of the metering box 8 to a horizontal state, thereby enabling the measurement of the weight of bezoar packaging under different requirements and improving the practicality of the entire device. By setting the reduction hole 40, the fan-shaped rocker 38 can rotate unidirectionally in its natural state in conjunction with the arc-shaped spring 41, preventing the end of the fan-shaped rocker 38 near the central rotating shaft 7 from deflecting downwards undesirably, thus improving the stability of the device when changing the measurement range of the metering box 8.

[0046] The working principle of this invention is as follows: When continuous plastic bag packaging of powdered artificial bezoar is required, the artificial bezoar powder is poured into the hopper 2, and the motor 6 is turned on simultaneously. This causes the central rotating shaft 7 to drive the material carrying ring 3 and the replenishing ring 4 to rotate synchronously. The artificial bezoar powder in the hopper 2 falls into the material carrying ring 3, and after being dispersed by multiple fan-shaped ramps 10 in the material carrying ring 3, it falls through the corresponding discharge holes 11 into multiple metering boxes 8 below. Since this is the initial metering stage, the artificial bezoar powder collected in each metering box 8... If the material weight does not reach the predetermined requirement, the tilted metering box 8, in conjunction with the elastic support of the corresponding thin spring 24, allows the powdery material in the feeding ring 4 to enter the corresponding metering box 8 below through the feeding hole 23. As the powder in the metering box 8 gradually increases, when the predetermined weight requirement is reached, the metering box 8 rotates to a horizontal position around the axis of the corresponding eccentric shaft 17. Then, through the traction of the traction rope 26, the baffle 27 at the corresponding position presses down and seals the feeding hole 23, stopping the feeding and thus achieving... While multiple metering boxes 8 rotate synchronously and continuously discharge material, the outer feeding ring 4 supplements the metering. When the metering box 8 rotates to the discharge position, the attraction of the metal block 30 by the fan-shaped magnet 32 ​​causes the corresponding discharge bottom plate 29 to flip open, thereby pouring the artificial bezoar powder that has reached the predetermined weight requirement into the connecting pipe 34 and conveying it to the input end of the plastic pad sealing machine. Then, the bagging and sealing operation is completed. At the same time, the rolling of the ball bearings in the first ball seat 31 on the fan-shaped magnet 32 ​​can also improve the surrounding of the metering box 8. The stability of the rotating shaft 7 when it rotates and is affected by magnetic traction allows for continuous metering and packaging of artificial bezoar without stopping the machine and continuously discharging material, thus improving the packaging efficiency of artificial bezoar. In addition, as the metering box 8 is rotated under weight and the baffle 27 is pulled down by the traction rope 26, the distance between the baffle 27 and the feeding hole 23 can be gradually reduced to control the speed at which bezoar powder is added to the metering box 8. Combined with the slow rotation of the metering box 8, precise feeding is achieved, improving the metering accuracy.

[0047] When the weight of the bezoar powder in a single metering box 8 is gradually increased using the feeding ring 4, the eccentric setting of the eccentric shaft 17 and the metering box 8 causes the metering box 8 to flip. Simultaneously, the tension spring 19 pulls one end of the arc-shaped rocker arm 44 upwards. Utilizing the lever principle, the arc-shaped rocker arm 44 rotates around its fulcrum on the corresponding connecting seat 43, and the other end presses down on the corresponding fan-shaped rocker arm 38. Compared to directly using the tension spring 19 to pull the metering box 8, using the arc-shaped rocker arm 44 makes it easier to control the angle at which the lighter bezoar powder causes the metering box 8 to flip. Furthermore, the limiting block 42, when the metering box 8 is unloading at the discharge hole 33, causes the fan-shaped magnet 32 ​​to attract and deflect the discharge base plate 29. The limiting block 42 then contacts the corresponding arc-shaped spring 41, causing the metering box 8 to be pulled by the arc-shaped spring 41 and the arc-shaped rocker arm 44. "The fixed position under the action not only achieves stable unloading, but also avoids the phenomenon of 'accidental material drop' caused by the loosening of the baffle 27 due to the accidental rotation of the metering box 8, thus improving the stability of the entire packaging device during operation. In addition, the snap-fit ​​installation method makes it easy to remove the loading ring 3 from the central rotating shaft 7, and the height of the central plate 15 can be adjusted by rotating the threaded tube 13. Thus, the initial tilt angle of the metering box 8 can be changed by using the arc-shaped spring 41, the fan-shaped seesaw 38 and the arc-shaped seesaw rod 44 in conjunction with the tension spring 19. This allows the loading capacity of the metering box 8 to be adjusted to a horizontal state, thereby realizing the measurement of the weight of bezoar packaging under different requirements and improving the practicality of the entire device. By setting the reduction hole 40, the fan-shaped seesaw 38 can be rotated in one direction in a natural state in conjunction with the arc-shaped spring 41, avoiding the undesirable downward deflection of the end of the fan-shaped seesaw 38 near the central rotating shaft 7, thereby improving the stability of the device when changing the measurement range of the metering box 8."
