DETAILED DESCRIPTION

[0041] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments will be described clearly and completely below with reference to the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but not to limit the scope of the present application.

[0042] Embodiment 1: Reference Figures 1-8 A packaging device for processing niclosamide ethanolamine salt powder, comprising a conveying device 1 for conveying bottle bodies, which can be a conveying belt, further comprising: a hopper 2 provided with a discharge pipe 3 at the bottom, which is fixedly installed on the conveying device 1, wherein the hopper 2 is used to store niclosamide ethanolamine salt powder, an inner pipe 4 is longitudinally and slidingly installed inside the discharge pipe 3, a lifting device 33 is fixedly installed at the bottom of the hopper 2, which is an electric telescopic rod or a telescopic cylinder, used to make the inner pipe 4 extend into the bottle body, and a lifting plate 34 fixedly connected with the inner pipe 4 is fixedly installed at the telescopic end of the lifting device 33; a sealing component for sealing the bottle opening, which is arranged at the lower end of the inner pipe 4, and when the inner pipe 4 moves upward and continues to fill, the sealing component keeps the state of sealing the bottle opening, the sealing component comprises a limiting plate 22 fixedly connected to the outer wall of the inner pipe 4, a ring-shaped sealing plate 5 is arranged around the outer wall of the lower end of the inner pipe 4, and a spring 21 is installed between the ring-shaped sealing plate 5 and the limiting plate 22.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In practice, at each filling, the second motor 36 is controlled by the controller to rotate a fixed number of turns.

[0048] Embodiment 2: Reference Figures 2-7 A packaging device for processing niclosamide ethanolamine salt powder, which is basically the same as embodiment 1, and further comprises:

[0049] The inner wall of the annular sealing plate 5 and the outer wall of the inner tube 4 are provided with an annular inner groove 9, the annular outer plate 6 is fixedly connected to the periphery of the annular sealing plate 5 through the frame body 7, the annular outer plate 6 and the outer wall of the annular sealing plate 5 are provided with an annular outer groove 8, the upper end of the annular inner groove 9 and the annular outer groove 8 are respectively rotatably installed with an inner ring plate 11 and an outer ring plate 10, the top of the inner ring plate 11 and the outer ring plate 10 are respectively provided with an exhaust groove 13 and an air inlet groove 12, 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 for driving the inner ring plate 11 and the outer ring plate 10 to synchronously and synchronously rotate, and the inner tube 4 is provided with a negative pressure part for inhaling air from the exhaust groove 13.

[0050] Specifically, when the inner tube 4 moves downward, the annular outer plate 6 will be placed on the bottle mouth of the bottle body, and the annular outer plate 6 will be limited by the bottle mouth, so that the annular outer plate 6 and the annular sealing plate 5 stay on the bottle mouth, and the annular outer groove 8 will be aligned with the inner wall of the bottle mouth. During the filling period, the negative pressure part inhales air from the exhaust groove 13, and the exhaust groove 13 inhales air from the upper end of the bottle body through the annular inner groove 9, and the bottle body inhales air from the air inlet groove 12 through the annular outer groove 8. When the airflow passes through the upper end of the bottle body, most of the scattered powder will be taken away, which can clean the powder near the bottle mouth on the one hand, and the powder in the bottle mouth is not easy to scatter in the surrounding environment and not easy to contaminate the bottle mouth after the annular sealing plate 5 and the bottle mouth are separated, which guarantees the sealing performance of the subsequent bottle cap. On the other hand, the powder can be effectively recycled, reducing the waste of powder.

[0051] The driving part includes a first motor 28 fixedly installed on the annular sealing plate 5, the output shaft of the first motor 28 is fixedly installed with a driving gear 29, the inner wall of the outer ring plate 10 is fixedly installed with an inner ring gear 30 engaged with the driving gear 29, the outer wall of the inner ring plate 11 is fixedly installed with an outer ring gear 31, and the annular sealing plate 5 is rotatably installed with an inert gear 32 engaged with the outer ring gear 31 and the driving gear 29.

[0052] Specifically, during the exhaust of the exhaust groove 13, the first motor 28 will drive the inert gear 32 to rotate synchronously with the inner ring gear 30 through the driving gear 29, and the inert gear 32 will drive the outer ring gear 31 to rotate synchronously, and the inner ring gear 30 and the outer ring gear 31 will drive the outer ring plate 10 and the inner ring plate 11 to rotate synchronously and in the same direction, so as to drive the exhaust groove 13 and the air inlet groove 12 to revolve around the axis of the inner tube 4 at the same time. Since the two are radially aligned, most of the airflow entering the bottle opening from the air inlet groove 12 will flow along the bottom surface of the annular sealing plate 5, thereby better cleaning the bottom of the annular sealing plate 5. Since the air inlet groove 12 is close to the inner wall of the bottle opening, the powder is less likely to approach the bottle opening. Since the exhaust groove 13 is close to the outer wall of the inner tube 4, the powder on the outer wall of the inner tube 4 can be sucked away (at the initial stage of filling the bottle body at the bottom, the generated powder is prone to stay on the outer wall of the inner tube 4), so that the powder on the outer wall of the inner tube 4 is less likely to fall and pollute the surrounding environment.

[0053] Embodiment 3: Refer to Figures 2-7 A packaging device for processing niclosamide ethanolamine salt powder, which is basically the same as embodiment 2, and further comprises:

[0054] The above-mentioned negative pressure part comprises a ring-shaped cover 14 sleeved on the outer wall of the lower end of the inner tube 4, the lower end of the ring-shaped cover 14 is rotatably connected to the upper end of the inner ring plate 11, the ring-shaped cover 14 is fixedly connected to the frame body 7, the ring-shaped cover 14 is fixedly connected with a negative pressure pipe 20, the outer wall of the inner tube 4 is fixedly connected with a collection box 17 for niclosamide ethanolamine salt powder, the collection box 17 is provided with a filter plate 19 for filtering the niclosamide ethanolamine salt powder, the end of the negative pressure pipe 20 extends to the inner bottom of the collection box 17, the top of the collection box 17 is fixedly connected with a device pipe 18, and the device pipe 18 is fixedly provided with a negative pressure fan for sucking air into the collection box 17.

[0055] Specifically, during the filling, the negative pressure fan in the device pipe 18 is started, the negative pressure fan sucks air into the collection box 17 through the device pipe 18, the collection box 17 sucks air into the ring-shaped cover 14 through the negative pressure pipe 20, the ring-shaped cover 14 sucks air into the exhaust groove 13, the exhaust groove 13 sucks air into the upper end of the bottle body through the annular inner groove 9, and the bottle body sucks air into the air inlet groove 12 through the annular outer groove 8. When the airflow passes through the upper end of the bottle body, most of the scattered powder will be carried away, and after entering the collection box 17, it will be filtered by the filter plate 19, and the collection box 17 will collect the sucked powder.

[0056] Embodiment 4: Refer to Figures 2-7 A packaging device for processing niclosamide ethanolamine salt powder, which is basically the same as embodiment 3, and further comprises:

[0057] The lower end of the annular sealing plate 5 is fixedly connected with a downward-arched annular boss 15, the lower end of the annular sealing plate 5 is fixedly connected with an annular air bag 16 which is arranged on the surface of the annular boss 15, the material of the annular air bag 16 is an elastic rubber film, the inner tube 4 is provided with an air exchange part for sucking or discharging air from the annular air bag 16, the air exchange part comprises a vertical plate 23 which is fixedly connected with the outer wall of the inner tube 4, a pressing plate 24 which is transversely arranged on the vertical plate 23, a guide plate 27 which is fixedly connected with the lower end of the pressing plate 24, an elastic air bag 25 which is arranged between the pressing plate 24 and the outer wall of the vertical plate 23, and a connecting pipe 26 which is fixedly connected with the elastic air bag 25 and extends into the annular air bag 16, when the vertical plate 23 moves downward by a preset distance along with the inner tube 4, the preset distance is the cavity height reserved in the bottle mouth after the filling is completed, the edge of the annular outer plate 6 will press the pressing plate 24 towards the vertical plate 23.

[0058] Specifically, due to the arrangement of the annular boss 15, the contact area of the bottom of the annular sealing plate 5 can be increased, the collection rate of the powder can be improved, the powder which is scattered can be intercepted by the annular air bag 16 on the lower surface of the annular boss 15 before reaching the bottle mouth, and 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 air outlet groove 13 in an arc-shaped path, and the arc-shaped surface of the annular boss 15 is just close to the arc-shaped path of the airflow, so that the efficiency of collecting the powder in the bottle mouth can be improved.

[0059] When the inner tube 4 moves downward, the vertical plate 23 will move downward, the vertical plate 23 will drive the elastic air bag 25, the pressing plate 24 and the guide plate 27 to move downward synchronously, when the lower end surface of the inner tube 4 passes through the preset filling height of the bottle, the guide plate 27 will slide over the edge of the annular outer plate 6, the pressing plate 24 will be pressed towards the vertical plate 23, the elastic air bag 25 will be pressed, the elastic air bag 25 will deliver the gas in the elastic air bag 25 to the annular air bag 16 through the connecting pipe 26, the annular air bag 16 will be inflated, the surface area of the annular air bag 16 can be further increased, and the effect of collecting the powder in the bottle mouth can be improved, when the inner tube 4 moves upward and reaches the preset filling height of the bottle, the filling work of the powder will be stopped, the guide plate 27 will be separated from the edge of the annular outer plate 6, the elastic air bag 25 will be elastically reset, the annular air bag 16 will be elastically reset, the surface area of the annular air bag 16 will be reduced, and the powder on the surface of the annular air bag 16 will be gathered or even fall back into the bottle, so that the annular air bag 16 can be more fully cleaned before the annular sealing plate 5 and the annular outer plate 6 leave the bottle mouth, the powder remaining on the surface of the annular air bag 16 will be less after the annular sealing plate 5 and the annular outer plate 6 leave the bottle mouth, and the probability of the powder polluting the surrounding environment can be effectively reduced.
