Description

Technical Field

[0001] The invention relates to the technical field of medicine powder production, in particular to a feeding device for conveying medicine powder. Background Art

[0002] In the pharmaceutical industry and many other fields involving drug powder processing, efficient, accurate and stable feeding and conveying of drug powder is a crucial production link. Traditional drug powder feeding methods often have many limitations and cannot meet the requirements of modern production for accuracy, efficiency and flexibility.

[0003] On the one hand, during the production or subsequent processing of drug powder, it is often necessary to transport the drug powder from the storage container to a specific processing equipment or packaging station. In the past, the feeding device may only have a simple conveying function and lack effective control over the state of the drug powder. For example, drug powder may clump during storage, which not only affects the uniform delivery of the drug powder, but also may cause the delivery pipeline to be blocked, thereby interrupting the production process, reducing production efficiency and increasing maintenance costs.

[0004] On the other hand, when the height difference between the discharge port of the powder conveyor and the feed port of the production device is large, when the powder is conveyed, part of the powder will directly enter the production device due to the effect of gravity, but some of the powder will fly in the air, which not only causes waste of powder, but also easily causes air pollution.

[0005] In addition, monitoring the quality of drug powder is also a key link in the production process. Being able to take samples and observe the status of drug powder in real time during the transportation process in order to promptly discover possible quality problems, such as impurities mixed in and changes in drug powder uniformity, is crucial to ensuring drug quality. However, most traditional feeding devices lack a convenient and effective sampling and observation mechanism, which leaves a certain blind spot in quality control during the production process.

[0006] Moreover, some traditional feeding methods, such as vacuum feeding, still have the problem of unevenness. During the vacuum feeding process, due to the difference in suction force and other factors on materials of different weights, stratification may occur. This not only affects the uniformity and consistency of the powder in subsequent processing, but may also have an adverse effect on the quality of the final product, further highlighting the shortcomings of existing feeding methods in ensuring uniform powder delivery.

[0007] Therefore, it is necessary to design a feeding device for powder delivery to solve the above problems. Summary of the invention

At the same time, with the controllable partition (opening and closing control is achieved through the sliding connection of the second electromagnet, spring and partition in the rectangular box), the sampled powder can be isolated and observed when necessary, and possible quality problems can be discovered in time;

[0022] 4. Compared with the existing technology, a stirring assembly is set in the lifting barrel, and the driving motor drives the vertical rod and multiple stirring rods to rotate, which can fully stir the powder. This effectively solves the problem of agglomeration of powder during storage or transportation, ensuring that the powder maintains good fluidity. At the same time, compared with the existing technology such as vacuum extraction and feeding, which may produce stratification due to materials of different mass sizes, this device mixes the powder evenly through stirring, avoids stratification, ensures the uniformity and consistency of the powder in subsequent processing, and helps to improve the quality of the final product.

[0038] Among them, it also includes a sampling component, which includes a vertical conveying box fixedly connected to the lower end of the fixing plate 9, and a feeding port is provided at the inner bottom of the vertical conveying box. After each addition of powder, the powder will submerge the feeding port. An observation box 35 is fixedly connected to the rear side of the lifting barrel 10. The observation box 35 is made of glass material, which is convenient for staff to observe the quality of the powder. The top space of the observation box 35 is connected to the top space of the vertical conveying box through a feeding pipe, and the bottom space of the observation box 35 is connected to the rear space of the lifting barrel 10 through a The return pipe 40 is connected, and a second conveying rod 41 is vertically provided in the vertical conveying box.

A clamping block 43 is fixedly connected to the telescopic end of the third pneumatic rod 42, and a clamping groove 44 matching the clamping block 43 is provided at the upper end of the second conveying rod 41.

[0039] Among them, a rectangular box 36 is fixedly connected to the right side of the observation box 35, a partition 39 is slidably connected inside the rectangular box 36, the left side of the partition 39 extends into the observation box 35, and a second electromagnet 37 is embedded in the right inner wall of the rectangular box 36. The second electromagnet 37 is elastically connected to the adjacent side of the partition 39 through a second spring 38, and the partition 39 is made of iron material.

[0040] The functional principle of the present invention can be explained by the following operation mode: First, the whole device is installed in a suitable working position, and the moving plate 1 is ensured to be placed stably, the components are firmly connected and the electrical circuits are connected normally. The driving motor 11, the first electromagnet 33 and the second electromagnet 37, and the first pneumatic rod 4, the second pneumatic rod 8, and the third pneumatic rod 42 are in a ready-to-start state;

[0041] The two second pneumatic rods 8 are controlled to stretch, so that the lifting barrel 10 moves downward, which is convenient for the staff to add the powder into the lifting barrel 10. At this time, since the slider 6 is located at the extreme position on the left, the infrared distance sensor 5 senses the distance and generates a corresponding electrical signal to be transmitted to the controller. The controller controls the first electromagnet 33 to be powered off. At this time, the distance between the V-shaped tube 21 and the horizontal conveying box 16 is relatively close. When the powder is added, the output shaft of the drive motor 11 is controlled to run clockwise to stir the powder to avoid the agglomeration of the powder. Since the block 43 is not located in the slot 44 at this time, the operation of the drive motor 11 will only drive the stirring component to rotate, and at the same time drive the short rod 13 to rotate through the first transmission component 12, but will not drive the second conveying rod 41 to rotate. Since the solenoid valve is in a power-off state, the powder in the lifting barrel 10 will not enter the horizontal conveying box 16 at this time.

[0042] During the stirring process, the staff can control the third pneumatic rod 42 to stretch and control the second electromagnet 37 to cut off the power at regular intervals. After the second electromagnet 37 is cut off, the partition 39 enters the observation box 35 under the elastic action of the second spring 38. After the third pneumatic rod 42 is stretched, the block 43 will enter the card slot 44. At this time, the rotation of the short rod 13 drives the second conveying rod 41 to rotate, and drives the second spiral blade 46 to rotate, so that part of the powder in the lifting barrel 10 is conveyed upward and then enters the observation box 35 through the feeding pipe. The staff can observe the quality of the powder in the lifting barrel 10. After each observation, the third pneumatic rod 42 is controlled to contract and the second electromagnet 37 is cut off, so that the partition 39 can be moved back, so that the powder in the observation box 35 can re-enter the lifting barrel 10.

[0043] When the quality of the powder is good, the staff controls the second pneumatic rod 8 to contract, drive the lifting bucket 10 to move upward, and controls the first pneumatic rod 4 to stretch, so that the V-shaped tube 21 moves to the top of the funnel, and then controls the second pneumatic rod 8 to stretch, and moves the lifting bucket 10 and the horizontal conveying box 16 to the specified position. At this time, the electrical signal generated by the infrared distance sensor 5 is transmitted to the controller, and the controller controls the first electromagnet 33 to be in a powered state, which generates a repulsive force on the magnetic block 32 so that the magnetic block 32 drives the V-shaped tube 21 into the deepest part of the funnel;

[0044] Since a one-way bearing is provided between the transmission rod 22 and the corresponding first bevel gear 15, when the output shaft of the drive motor 11 rotates clockwise, the transmission rod 22 cannot be driven to rotate. When the lifting barrel 10 moves to the specified position, the output shaft of the drive motor 11 is controlled to rotate counterclockwise, and the solenoid valve is opened. At this time, the transmission rod 22 drives the first conveying rod 24 to rotate, and then drives the first spiral blade 47 to rotate. At this time, the powder enters the transverse conveying box 16, and is conveyed to the right side and added to the funnel.

[0045] When the first electromagnet 33 is just energized, the repulsive force on the magnetic block 32 is the largest, so that the V-shaped tube 21 is located at the bottom of the funnel. As the first conveying rod 24 rotates, the blanking tube 19 is driven to rotate, and the threaded rod 27 is driven to rotate, so that the conductive block moves upward. The rotation of the blanking tube 19 drives the V-shaped tube 21 to rotate, so that the powder is evenly sprinkled in the funnel.

[0046] In the process of the conductive block moving upward, the cross-sectional area of ​​the copper rod 48 is continuously reduced, and at the same time, the length of the copper rod 48 connected to the circuit is continuously increased, so that the resistance value of the copper rod 48 connected to the circuit is continuously increased, and then the current passing through the first electromagnet 33 is continuously reduced. As the height of the powder in the funnel continues to increase, the V-shaped tube 21 is continuously moved upward, thereby reducing the time for each powder to fall, and avoiding the occurrence of air pollution caused by powder dust.

[0047] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
