[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0029] like Figure 1-4 As shown, a powdered medicine packaging device includes a base plate, a guide nozzle 7, a longitudinal heat sealing mechanism, and a transverse heat sealing mechanism. The base plate is fixed on the main body 1, which is a box-type structure. A material tray 2 is rotatably connected above the base plate. The bottom of the material tray 2 is flat, and the base plate is circular with a flat contact surface corresponding to the bottom of the material tray 2. A rotating shaft is provided in the middle of the material tray 2. The rotating shaft passes downward through the base plate and is fixed to the main body 1. A stepper motor corresponding to the material tray 2 is provided above the main body 1. An external toothed ring is provided on the outer wall of the material tray 2. The main shaft of the stepper motor is connected to the external toothed ring of the material tray 2 through a drive gear, thereby driving the material tray 2 to rotate about the rotating shaft.
[0030] The material tray 2 contains powder. The bottom of the material tray 2 is provided with multiple material troughs 3 evenly distributed around its circumference. A discharge hole is provided on the bottom plate. The side of the bottom plate extends outward from the main body 1. The discharge hole is located on the part of the bottom plate that extends outward from the main body 1. As the material tray 2 rotates, the material troughs 3 pass through the discharge hole in sequence, thereby driving the powder in the material troughs 3 into the guide nozzle 7. The guide nozzle 7 is located below the discharge hole. Its upper end is fixedly connected to the bottom plate, and its lower end extends longitudinally, thereby guiding the powder inside.
[0031] The longitudinal heat sealing mechanism is fixed to the side wall of the main body 1 and located in the middle of the side of the guide nozzle 7 to perform longitudinal heat sealing on both sides of the packaging film passing through the longitudinal heat sealing mechanism; the longitudinal heat sealing mechanism is provided with guide plates 8 that hug the sides of the guide nozzle 7, and there is a gap between the guide plates 8 and the guide nozzle 7 corresponding to the packaging film. After the packaging film passes through the gap of the longitudinal heat sealing mechanism of the guide plates 8, a cylindrical structure including the guide nozzle 7 is formed, so that the powder inside the guide nozzle 7 can be introduced into the packaging film.
[0032] The packaging film is guided by a gap between the guide plate 8 and the guide nozzle 7 to ensure the stability of the packaging film and prevent displacement. The transverse heat sealing mechanism is located directly below the guide nozzle 7. The packaging film, after passing through the longitudinal heat sealing mechanism, is transversely sealed to form an independent cavity for the corresponding powdered medicine.
[0033] In an optional embodiment, the material trough 3 is a circular internal threaded assembly with a feeding plate 4. The feeding plate 4 has a central hole in the middle. The amount of powder feeding can be adjusted by replacing the feeding plate 4 with a central hole of different diameters.
[0034] Inside the material tray 2, there is a scraper 5 located directly above the discharge hole. The scraper 5 has a flat surface corresponding to the bottom of the material tray 2, so that it can stick to the upper surface of the bottom of the material tray 2, allowing only the powder in the material trough 3 or the feeding plate 4 to enter the discharge hole.
[0035] In this embodiment, a vibration module is provided on the base plate to prevent powder from remaining in the discharge hole or trough 3 through vibration.
[0036] The main body 1 of the scraper 5 is a disc corresponding to the material trough 3. The scraper 5 is provided with a connecting part, which is fixed to one end of the rotating shaft that extends into the material trough 2.
[0037] In an optional embodiment, the longitudinal heat sealing mechanism includes two fixed plates 9 spaced apart on the main body 1. The fixed plates 9 are fixed to the main body 1 by bolts. Each of the two fixed plates 9 is provided with a first heat sealing plate 14 extending longitudinally. The first heat sealing plate 14 is an electric heating plate. A sliding column is provided on the first heat sealing plate 14. The sliding column passes outward through the fixed plate 9. A compression spring 15 corresponding to the electric heating plate and the fixed plate 9 is provided on the sliding column, so that the two first heat sealing plates 14 have a relative compression tendency, thereby causing the two first heat sealing plates 14 to compress each other and heat seal the packaging film, so as to heat seal the edge of the packaging film and form a cylindrical structure corresponding to the guide nozzle 7.
[0038] Two guide plates 8 are fixed on two fixed plates 9. The side of the two guide plates 8 away from the fixed plates 9 is provided with a gap corresponding to the packaging film, so that the packaging film can be inserted between the fixed plate 9 and the guide nozzle 7. The upper end of the guide plate 8 expands outward to form a trumpet-shaped guiding structure corresponding to the packaging film, ensuring the guidance of the packaging film and making the packaging film less prone to deviation.
[0039] In this embodiment, a conveyor roller 10 is rotatably connected to the main body 1 between the longitudinal heat sealing mechanism and the transverse heat sealing mechanism. The main shaft of the conveyor roller 10 is rotatably connected to the side wall of the main body 1. The two conveyor rollers 10 clamp the side edge of the packaging film after it has been heat sealed. One of the conveyor rollers 10 is connected to a driving device to drive the packaging film to move downward. The driving device is a drive motor installed in the main body 1, thereby driving the packaging film to move downward.
[0040] The main body 1 is provided with a roller 6 corresponding to the packaging film. The packaging film is wound on the sleeve, and the sleeve is rotatably connected to the roller 6. In this way, the sleeve can be rotated on the roller 6 under the pull of the conveyor roller 10, so that the packaging film can be fed.
[0041] In an optional embodiment, the transverse heat-sealing mechanism includes two second heat-sealing plates 12, which are electric heating plates. One second heat-sealing plate 12 is horizontally fixed on the main body 1, and the other fixed plate 9 is connected to the main body 1 via a drive rod 13. Driven by the drive rod 13, the plate moves towards the main body 1 to clamp and heat-seal the packaging film. This clamping action divides the packaging film heat-sealed into a cylinder by the longitudinal heat-sealing mechanism. The transverse heat-sealing mechanism is located below the guide nozzle 7, allowing for the placement of powder. The heat sealing of the transverse heat-sealing mechanism forms independent cavities for the corresponding powder. A cutting blade cuts the heat-sealed portion of the transverse heat-sealing mechanism to form independent powder packages. The second heat-sealing plates 12 are correspondingly mounted on the support plate 16 for support. The drive rod 13 is a cylinder or electric cylinder located inside the main body 1, with its piston rod extending out of the main body 1 and connected to the support plate 16.
[0042] The guide nozzle 7 has downward-extending support bars 11 on both sides at the lower end to ensure that the powder completely enters the corresponding packaging film. The conveyor roller 10 is lower than the elevation of the lower end of the guide nozzle, and the support bars 11 extend in front of the conveyor roller 10.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
