Description

Technical Field

[0001] This invention belongs to the technical field of powder packaging equipment, specifically, it relates to a packaging equipment for processing molluscicide ethanolamine salt powder. Background Technology

[0002] Snail-killing ethanolamine salt powder is a chemical agent specifically designed to kill Oncomelania snails. Its active ingredient is a water-soluble modified serotonin. It effectively kills Oncomelania snails, the intermediate host of schistosomiasis, by disrupting their nervous system and metabolic function. It is one of the key prevention and control products in the public health field used to block the spread of schistosomiasis. It usually needs to be diluted with water and sprayed on waters or mudflats where Oncomelania snails are rampant.

[0003] During the processing of molluscicide ethanolamine salt powder, when this fine powder needs to be dispensed into bottles using filling equipment, due to the powder's light texture and good flowability, some powder is easily scattered and spilled during filling due to air disturbance or mutual impact between powder particles. This not only causes it to fall into the equipment and work area, contaminating the clean workshop environment and posing a potential risk to the occupational health of operators, but also results in direct material loss, leading to unnecessary production waste and increased costs. On the other hand, some powder may remain on the bottle mouth, potentially affecting the sealing of the subsequent bottle cap. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a packaging device for processing molluscicide ethanolamine salt powder that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A packaging device for processing molluscicide ethanolamine salt powder includes a conveying device and further includes: a material hopper with a discharge pipe at the bottom, fixedly installed on the conveying device, wherein an inner tube is longitudinally slidably installed inside the discharge pipe; a lifting device is fixedly installed at the bottom of the material hopper; and a lifting plate fixedly connected to the inner tube is fixedly installed at the telescopic end of the lifting device; and a sealing component is disposed at the lower end of the inner tube, which remains in a sealed state when the inner tube moves upward and continuously fills the bottle.

[0006] Preferably, the sealing component includes a limiting plate fixedly connected to the outer wall of the inner tube, an annular sealing plate is arranged around the lower outer wall of the inner tube, and a spring is installed between the annular sealing plate and the limiting plate.

[0007] Furthermore, an annular inner groove is provided between the inner wall of the annular sealing plate and the outer wall of the inner tube. An annular outer plate is fixedly connected to the annular sealing plate around its perimeter via a frame. An annular outer groove is provided between the annular outer plate and the outer wall of the annular sealing plate. An inner ring plate and an outer ring plate are rotatably installed at the upper ends of the annular inner groove and the annular outer groove, respectively. An exhaust groove and an air inlet groove are respectively provided at the top of the inner ring plate and the outer ring plate, and the exhaust groove and the air inlet groove are radially aligned. A driving part is provided on the annular sealing plate to drive the inner ring plate and the outer ring plate to rotate synchronously and in the same direction. A negative pressure part is provided on the inner tube to draw air from the exhaust groove.

[0008] Furthermore, the drive unit includes a first motor fixedly mounted on the annular sealing plate, a drive gear fixedly mounted on the output shaft of the first motor, an inner ring gear meshing with the drive gear fixedly mounted on the inner wall of the outer ring plate, an outer ring gear fixedly mounted on the outer wall of the inner ring plate, and an inertial gear rotatably mounted on the annular sealing plate, meshing with the outer ring gear and the drive gear.

[0009] Furthermore, the negative pressure section includes an annular cover fitted onto the outer wall of the lower end of the inner tube. The lower end of the annular cover is rotatably connected to the upper end of the inner ring plate. The annular cover is fixedly connected to the frame, and a negative pressure pipe is fixedly connected to the annular cover.

[0010] Furthermore, a collection box is fixedly connected to the outer wall of the inner tube, a filter plate is installed inside the collection box, the end of the negative pressure pipe extends to the inner bottom of the collection box, a device pipe is fixedly connected to the top of the collection box, and a negative pressure fan is fixedly installed inside the device pipe.

[0011] Furthermore, the lower end of the annular sealing plate is fixedly connected to a downward-arched annular boss, and the lower end of the annular sealing plate is fixedly connected to an annular airbag resting on the surface of the annular boss. The inner tube is provided with a ventilation section for inhaling or exhaling air from the annular airbag.

[0012] Furthermore, the ventilation section includes a vertical plate fixedly connected to the outer wall of the inner tube. A pressure plate is also horizontally installed on the vertical plate. A guide plate is fixedly connected to the lower end of the pressure plate. An elastic airbag is installed between the pressure plate and the outer wall of the vertical plate. A connecting pipe extending into the annular airbag is fixedly connected to the elastic airbag. When the vertical plate moves downward a preset distance with the inner tube, the edge of the annular outer plate will press the pressure plate towards the vertical plate.

[0013] Preferably, a horizontal frame is fixedly connected to the upper port of the material bucket, a second motor is fixedly installed on the horizontal frame, a vertical tube is fixedly connected to the output end of the second motor, an inner rod is slidably installed longitudinally inside the vertical tube, a spiral blade extending into the inner tube is fixedly connected to the lower end of the inner rod, a support frame is fixedly connected to the bottom of the inner tube, and the bottom of the spiral blade is rotatably connected to the support frame.

[0014] A method for packaging molluscicide ethanolamine salt powder includes the following steps: S1. The bottle is conveyed to the bottom of the inner tube by a conveying device; S2. Move the inner tube downwards and insert it into the bottle until the lower end of the inner tube is close to the bottom of the bottle, and make the annular sealing plate and the annular outer plate cover the bottle mouth. S3. While moving the inner tube upward, fill the bottle with powder; S4. Make the exhaust channel continuously draw air into the bottle opening, and make the air inlet channel continuously draw in outside air. S5. When the inner tube rises to the preset filling height of the bottle, stop filling the bottle with powder; S6. After the inner tube, the annular sealing plate, and the annular outer plate are separated from the bottle mouth, move the other bottle to directly below the inner tube. S7. Repeat steps S1-S6 above to fill all bottles in sequence.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. This invention uses a lifting device to drive the inner tube to slide downwards in the discharge pipe. The annular outer plate is limited by the bottle mouth, so that the annular sealing plate stays on the bottle mouth. Then, the powder in the material bucket is continuously transported into the bottle body through the inner tube by the spiral blade. At this time, the inner tube is continuously moved upwards and reset by the lifting device, so that the bottle body can be gradually filled. This bottom-up filling action can effectively reduce the probability of powder scattering. On the one hand, it makes the filling weight more accurate, and on the other hand, it makes the powder less likely to pollute the surrounding environment.

[0016] 2. By using a spring, the annular outer plate of this invention will always press against the bottle opening, ensuring that the powder generated during filling remains inside the bottle. This effectively prevents the powder from escaping from the bottle and indirectly reduces powder waste.

[0017] 3. This invention starts the first motor and the negative pressure fan inside the device tube, which drives the exhaust slot and the air inlet slot to revolve around the axis of the inner tube. The negative pressure fan collects the powder through the collection box. On the one hand, it can clean up the powder near the bottle mouth. After the subsequent annular sealing plate leaves the bottle mouth, the powder in the bottle mouth is less likely to drift into the surrounding environment and less likely to contaminate the bottle mouth, ensuring the sealing of the subsequent bottle cap. On the other hand, it can effectively recycle the powder and reduce powder waste.

[0018] 4. By having the exhaust groove and the air inlet groove revolve around the axis of the inner tube simultaneously, most of the airflow entering the bottle mouth from the air inlet groove will flow along the bottom surface of the annular sealing plate, thus better cleaning the bottom of the annular sealing plate. Furthermore, since the air inlet groove is close to the inner wall of the bottle mouth, it makes it difficult for powder to approach the bottle mouth. The exhaust groove is close to the outer wall of the inner tube, which can also suck away the powder on the outer wall of the inner tube, making it less likely for the powder on the outer wall of the inner tube to fall off and pollute the surrounding environment.

[0019] 5. By setting the annular protrusion, the present invention can increase the contact area at the bottom of the annular sealing plate, improve the powder collection rate, and allow the dispersed powder to be intercepted by the annular airbag on the lower surface of the annular protrusion before it approaches the bottle mouth. At the same time, it can make fuller use of the airflow passing through the lower surface of the annular sealing plate, thus improving the efficiency of collecting powder at the bottle mouth.

[0020] 6. In this invention, when the inner tube moves downward and the lower end of the inner tube exceeds the preset filling height of the bottle, the elastic airbag will be compressed. The elastic airbag will transport the internal gas to the annular airbag through the connecting tube, and the annular airbag will expand, thereby further increasing the surface area of ​​the annular airbag and thus improving the effect of collecting powder in the bottle mouth.

[0021] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] Example 1: Refer to Figures 1-8 A packaging device for processing molluscicide ethanolamine salt powder includes a conveying device 1 for conveying bottles, which can be a conveyor belt. It also includes a material hopper 2 with a discharge pipe 3 at the bottom, fixedly installed on the conveying device 1. The material hopper 2 is used to store molluscicide ethanolamine salt powder. An inner tube 4 is longitudinally slidably installed inside the discharge pipe 3. A lifting device 33 is fixedly installed at the bottom of the material hopper 2. The lifting device 33 is an electric telescopic rod or a telescopic cylinder used to extend the inner tube 4 into the bottle. A lifting plate 34, fixedly connected to the inner tube 4, is fixedly installed at the telescopic end of the lifting device 33. A sealing component for sealing the bottle opening is located at the lower end of the inner tube 4. When the inner tube 4 moves upward and continuously fills, the sealing component maintains the state of sealing the bottle opening. The sealing component includes a limiting plate 22 fixedly connected to the outer wall of the inner tube 4. An annular sealing plate 5 is arranged around the lower outer wall of the inner tube 4. A spring 21 is installed between the annular sealing plate 5 and the limiting plate 22.

[0026] Specifically, in use, the bottle containing the molluscicide ethanolamine salt powder is conveyed to the area directly below the annular sealing plate 5 via the conveying device 1. Then, the lifting device 33 drives the inner tube 4 to slide downwards within the discharge pipe 3, allowing the annular sealing plate 5 to stop at the bottle opening. The continuously downward-moving inner tube 4 compresses the spring 21 via the limiting plate 22. When the lower end of the inner tube 4 approaches the inner bottom of the bottle, the inner tube 4 continuously pours powder into the bottle. The lifting device 33 then continuously moves the inner tube 4 upwards to reset it, gradually filling the bottle. This bottom-up filling action effectively reduces the probability of powder scattering, making the filling weight more efficient. This design improves precision while also preventing powder from contaminating the surrounding environment. Due to the spring 21, the annular sealing plate 5 always presses against the bottle opening, ensuring that the powder generated during filling remains inside the bottle. This effectively prevents the powder from escaping from the bottle, indirectly reducing powder waste. When the inner tube 4 reaches the preset filling height (the maximum accumulation height of the powder will be less than the height of the bottle, generally about 1cm), the inner tube 4 stops filling. When the inner tube 4 rises to the same level as the bottle opening, the upward-moving inner tube 4 will drive the annular sealing plate 5 to move upward and away from the bottle, allowing for filling of the next bottle.

[0027] In practice, to improve the level of automation, the position of the bottle can be located by industrial camera detection equipment and control equipment. For example, after the conveyor 1 conveys the bottle to the bottom of the inner tube 4, the industrial camera detects that the bottle has reached the designated position. Then, the control equipment shuts down the conveyor 1, so that the bottle stops moving during filling. Then the controller controls the inner tube 4 to move downward to complete the filling work.

[0028] A horizontal frame 35 is fixedly connected to the upper end of the aforementioned material hopper 2. A second motor 36 is fixedly installed on the horizontal frame 35. A vertical pipe 37 is fixedly connected to the output end of the second motor 36. An inner rod 38 is longitudinally slidably installed inside the vertical pipe 37. The axial cross-section of the inner rod 38 is a regular polygon, such as a hexagon. A spiral blade 39 extending into the inner pipe 4 is fixedly connected to the lower end of the inner rod 38. The spiral blade 39 is equivalent to an auger for conveying powder. A support frame 40 is fixedly connected to the bottom of the inner pipe 4. The bottom of the spiral blade 39 is rotatably connected to the support frame 40.

[0029] Specifically, when the inner tube 4 needs to continuously convey powder downwards, the second motor 36 is started. The second motor 36 will drive the inner rod 38 and the spiral blade 39 to rotate continuously through the vertical tube 37. The spiral blade 39 can then continuously convey the powder in the material bucket 2 to the bottle body through the inner tube 4. When it is necessary to stop conveying, the second motor 36 can be turned off. While the inner tube 4 drives the spiral blade 39 to move up and down, the spiral blade 39 will also drive the inner rod 38 to slide up and down inside the vertical tube 37.

[0030] In practice, during each filling, the second motor 36 can be rotated a fixed number of times by the controller.

[0031] Example 2: Refer to Figures 2-7 A packaging device for processing molluscicide ethanolamine salt powder is basically the same as in Example 1, but further: An annular inner groove 9 is provided between the inner wall of the annular sealing plate 5 and the outer wall of the inner tube 4. An annular outer plate 6 is fixedly connected around the annular sealing plate 5 by the frame 7. An annular outer groove 8 is provided between the annular outer plate 6 and the outer wall of the annular sealing plate 5. An inner ring plate 11 and an outer ring plate 10 are rotatably installed at the upper ends of the annular inner groove 9 and the annular outer groove 8, respectively. An exhaust groove 13 and an air inlet groove 12 are respectively provided at the top of the inner ring plate 11 and the outer ring plate 10, and the exhaust groove 13 and the air inlet groove 12 are radially aligned. The annular sealing plate 5 is provided with a driving part that drives the inner ring plate 11 and the outer ring plate 10 to rotate synchronously and in the same direction. The inner tube 4 is provided with a negative pressure part that draws air from the exhaust groove 13.

[0032] Specifically, when the inner tube 4 moves downward, the annular outer plate 6 rests on the bottle mouth and is limited by the bottle mouth, so that the annular outer plate 6 and the annular sealing plate 5 stay on the bottle mouth. The annular outer groove 8 is aligned vertically with the inner wall of the bottle mouth. During filling, air is drawn into the exhaust groove 13 through the negative pressure section, and the exhaust groove 13 draws air into the upper port of the bottle through the annular inner groove 9. The bottle body draws air into the air inlet groove 12 through the annular outer groove 8. When the airflow passes through the upper port of the bottle, it carries away most of the scattered powder. On the one hand, it can clean up the powder near the bottle mouth. After the annular sealing plate 5 leaves the bottle mouth, the powder in the bottle mouth is less likely to drift into the surrounding environment and less likely to contaminate the bottle mouth, ensuring the sealing of the subsequent bottle cap. On the other hand, it can effectively recycle the powder and reduce powder waste.

[0033] The aforementioned drive unit includes a first motor 28 fixedly mounted on the annular sealing plate 5. A drive gear 29 is fixedly mounted on the output shaft of the first motor 28. An inner ring gear 30 that meshes with the drive gear 29 is fixedly mounted on the inner wall of the outer ring plate 10. An outer ring gear 31 is fixedly mounted on the outer wall of the inner ring plate 11. An inertial gear 32 that meshes with the outer ring gear 31 and the drive gear 29 is rotatably mounted on the annular sealing plate 5.

[0034] Specifically, during the exhaust of the exhaust groove 13, the first motor 28 drives the inertial gear 32 and the inner ring gear 30 to rotate synchronously via the drive gear 29. The inertial gear 32 drives the outer ring gear 31 to rotate synchronously. The inner ring gear 30 and the outer ring gear 31 drive the outer ring plate 10 and the inner ring plate 11 to rotate synchronously and in the same direction. This causes the exhaust groove 13 and the air inlet groove 12 to revolve around the axis of the inner tube 4. Since the two are radially aligned, most of the airflow entering the bottle mouth from the air inlet groove 12 will flow along the bottom surface of the annular sealing plate 5, which can better clean the bottom of the annular sealing plate 5. Furthermore, since the air inlet groove 12 is close to the inner wall of the bottle mouth, it makes it difficult for the powder to approach the bottle mouth. The exhaust groove 13 is close to the outer wall of the inner tube 4, which can also suck away the powder on the outer wall of the inner tube 4 (in the initial stage of filling at the bottom of the bottle, the powder generated is easy to stay on the outer wall of the inner tube 4), making it difficult for the powder on the outer wall of the inner tube 4 to fall off and pollute the surrounding environment.

[0035] Example 3: Reference Figures 2-7 A packaging device for processing molluscicide ethanolamine salt powder is basically the same as in Example 2, but further: The aforementioned negative pressure section includes an annular cover 14 fitted onto the outer wall of the lower end of the inner tube 4. The lower end of the annular cover 14 is rotatably connected to the upper end of the inner ring plate 11. The annular cover 14 is fixedly connected to the frame 7. A negative pressure pipe 20 is fixedly connected to the annular cover 14. A collection box 17 for molluscicide ethanolamine salt powder is fixedly connected to the outer wall of the inner tube 4. A filter plate 19 for filtering molluscicide ethanolamine salt powder is installed inside the collection box 17. The end of the negative pressure pipe 20 extends to the inner bottom of the collection box 17. A device pipe 18 is fixedly connected to the top of the collection box 17. A negative pressure fan for sucking air from the collection box 17 is fixedly installed inside the device pipe 18.

[0036] Specifically, during the filling process, the negative pressure fan inside the device pipe 18 is activated. The negative pressure fan draws air into the collection box 17 through the device pipe 18, and the collection box 17 draws air into the annular cover 14 through the negative pressure pipe 20. The annular cover 14 then draws air into the exhaust groove 13, which in turn draws air into the upper port of the bottle through the inner annular groove 9. The bottle draws air into the air inlet groove 12 through the outer annular groove 8. When the airflow passes through the upper port of the bottle, it carries away most of the scattered powder and enters the collection box 17, where it is filtered by the filter plate 19. The collection box 17 then collects the collected powder.

[0037] Example 4: Reference Figures 2-7 A packaging device for processing molluscicide ethanolamine salt powder is basically the same as in Example 3, but further: The lower end of the aforementioned annular sealing plate 5 is fixedly connected to a downward-arched annular protrusion 15. The lower end of the annular sealing plate 5 is fixedly connected to an annular airbag 16 that rests on the surface of the annular protrusion 15. The annular airbag 16 is made of an elastic rubber membrane. The inner tube 4 is provided with a ventilation section for inhaling or venting air from the annular airbag 16. The ventilation section includes a vertical plate 23 fixedly connected to the outer wall of the inner tube 4. A pressure plate 24 is also horizontally installed on the vertical plate 23. A guide plate 27 is fixedly connected to the lower end of the pressure plate 24. An elastic airbag 25 is installed between the pressure plate 24 and the outer wall of the vertical plate 23. A connecting tube 26 extending into the annular airbag 16 is fixedly connected to the elastic airbag 25. When the vertical plate 23 moves downward a preset distance with the inner tube 4, the preset distance is the height of the cavity reserved at the bottle mouth after the bottle is filled. The edge of the annular outer plate 6 will press the pressure plate 24 towards the vertical plate 23.

[0038] Specifically, due to the setting of the annular protrusion 15, the contact area at the bottom of the annular sealing plate 5 can be increased, the powder collection rate can be improved, and the scattered powder can be intercepted by the annular airbag 16 on the lower surface of the annular protrusion 15 before it approaches the bottle mouth. At the same time, the airflow passing through the lower surface of the annular sealing plate 5 can be more fully utilized, because the airflow entering the bottle mouth from the air inlet groove 12 will enter the exhaust groove 13 in an arc path, and the arc surface of the annular protrusion 15 is close to the arc path of the airflow, thus improving the efficiency of collecting powder at the bottle mouth.

[0039] As the inner tube 4 moves downward, it also drives the vertical plate 23 downward. The vertical plate 23 drives the elastic airbag 25, the pressure plate 24, and the guide plate 27 to move downward simultaneously. When the lower end of the inner tube 4 passes the preset filling height of the bottle, the guide plate 27 slides over the edge of the annular outer plate 6, causing the pressure plate 24 to press against the vertical plate 23. The elastic airbag 25 is then compressed, and the elastic airbag 25 transmits the internal gas to the annular airbag 16 through the connecting pipe 26. The annular airbag 16 expands, further increasing its surface area and thus improving the collection effect of powder from the bottle opening. Meanwhile, as the inner tube 4 moves upward... When the preset filling height of the bottle is reached, the powder filling process will stop. The guide plate 27 will separate from the edge of the annular outer plate 6, the elastic airbag 25 will elastically reset, and the annular airbag 16 will elastically reset as well. The surface area of ​​the annular airbag 16 will decrease as it resets, so the powder on its surface will accumulate and may even fall back into the bottle. This allows the annular airbag 16 to be cleaned more thoroughly before the annular sealing plate 5 and the annular outer plate 6 leave the bottle opening, resulting in less powder remaining on the surface of the annular airbag 16 after the annular sealing plate 5 and the annular outer plate 6 leave the bottle opening. This effectively reduces the probability of powder contamination of the surrounding environment.

[0040] Example 5: Refer to Figures 1-8 A method for packaging molluscicide ethanolamine salt powder includes the following steps: S1. The bottle is conveyed to the bottom of the inner tube 4 by the conveying device 1; S2. Move the inner tube 4 downward and insert it into the bottle until the lower end of the inner tube 4 is close to the bottom of the bottle, and make the annular sealing plate 5 and the annular outer plate 6 cover the bottle mouth. S3. While moving the inner tube 4 upward, fill the bottle with powder. S4. The exhaust channel 13 continuously draws air into the bottle opening, and the air inlet channel 12 continuously draws in outside air. S5. When the inner tube 4 rises to the preset filling height of the bottle, stop filling the bottle with powder. S6. After the inner tube 4, the annular sealing plate 5 and the annular outer plate 6 are separated from the bottle mouth, move another bottle to directly below the inner tube 4. S7. Repeat steps S1-S6 above to fill all bottles in sequence.

[0041] In use, the bottle containing the molluscicide ethanolamine salt powder is conveyed to the area directly below the annular sealing plate 5 via the conveying device 1. Then, the lifting device 33 drives the inner tube 4 to slide downwards within the discharge pipe 3. When the annular outer plate 6 rests on the bottle opening, it is stopped by the opening, causing the annular sealing plate 5 to remain on the opening. The annular outer groove 8 is aligned vertically with the inner wall of the bottle opening. The continuously downward-moving inner tube 4 compresses the limiting plate 22 and spring 21. When the lower end of the inner tube 4 approaches the bottom of the bottle, the second motor 36 is activated. The second motor 36 drives the inner rod 38 and the spiral blade 39 to rotate continuously via the vertical pipe 37. The spiral blade 39 continuously conveys the powder from the material container 2 into the bottle through the inner tube 4. At this point, the lifting device 33 moves the inner tube 4 upwards to reset it, thus gradually... The gradual filling of the bottle, this bottom-up filling action, can effectively reduce the probability of powder scattering. On the one hand, it makes the filling weight more accurate, and on the other hand, it makes the powder less likely to pollute the surrounding environment. Due to the setting of spring 21, the annular outer plate 6 will always press against the bottle mouth, so that the powder generated during filling is always inside the bottle, which can effectively prevent the powder from scattering out of the bottle and indirectly reduce powder waste. When the height of the inner tube 4 reaches the preset filling height (the maximum accumulation height of the powder will be less than the height of the bottle, generally about 1cm), the second motor 36 is turned off, so that the inner tube 4 stops filling. When the inner tube 4 rises to the same level as the bottle mouth, the inner tube 4 continues to rise, which will drive the annular outer plate 6 and the annular sealing plate 5 to move upward and away from the bottle, and then the next bottle can be filled.

[0042] During filling, the first motor 28 and the negative pressure fan inside the device pipe 18 are started. The first motor 28 drives the inertial gear 32 and the inner ring gear 30 to rotate synchronously via the drive gear 29. The inertial gear 32 drives the outer ring gear 31 to rotate synchronously. The inner ring gear 30 and the outer ring gear 31 drive the outer ring plate 10 and the inner ring plate 11 to rotate synchronously and in the same direction. This causes the exhaust groove 13 and the air inlet groove 12 to revolve around the axis of the inner pipe 4. The negative pressure fan draws air into the collection box 17 through the device pipe 18. The collection box 17 draws air into the annular cover 14 through the negative pressure pipe 20. The annular cover 14 draws air into the exhaust groove 13. The exhaust groove 13 draws air into the upper port of the bottle through the inner annular groove 9. The bottle draws air into the air inlet groove 12 through the outer annular groove 8. When the airflow passes through the upper port of the bottle, it carries away most of the scattered powder and enters the collection box 17. The powder is filtered by the filter plate 19 and collected by the collection box 17. This serves two purposes: firstly, it cleans the powder near the bottle opening, preventing the powder from easily drifting into the surrounding environment and contaminating the bottle opening after the annular sealing plate 5 leaves the bottle opening, thus ensuring the sealing of the subsequent bottle cap; secondly, it effectively recycles the powder, reducing waste. Since the exhaust groove 13 and the air inlet groove 12 revolve around the axis of the inner tube 4 and are radially aligned, most of the airflow entering the bottle opening from the air inlet groove 12 flows along the bottom surface of the annular sealing plate 5, which better cleans the bottom of the annular sealing plate 5. Furthermore, since the air inlet groove 12 is close to the inner wall of the bottle opening, it prevents the powder from easily approaching the bottle opening. The exhaust groove 13 is close to the outer wall of the inner tube 4, which can also suck up the powder on the outer wall of the inner tube 4, preventing the powder on the outer wall of the inner tube 4 from falling and contaminating the surrounding environment.
