DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figures 1 to 3 , the utility model provides a technical solution:
[0019] A PAM integrated dosing device comprises a base 1, a medicine storage shell 2 installed above the base 1, a medicine dispensing box 3 and a water storage shell 4, and a control panel 5 installed on the outer surface of the base 1. A lifting mechanism for conveying medicine powder to the top is installed inside the medicine storage shell 2, a funnel 6 and a pump body are installed on the top of the medicine dispensing box 3, and a guide pipe 7 for adding the medicine powder lifted to the top into the funnel 6 is installed on one side of the lifting mechanism. A support plate 9 is fixedly provided at the bottom of the medicine dispensing box 3, a medicine storage box 8 connected to the medicine dispensing box is installed below the support plate 9, and a mixing box 10 is installed above it. One end of the pump body is connected to the inside of the water storage shell 4 through a water inlet pipe, and a solenoid valve is installed at the connection point, and the other end is connected to the mixing box 10 through a water outlet pipe. A discharge pipe 11 is installed at one end of the top of the mixing box 10, and a stirring assembly and a liquid level sensor are installed inside. A dispensing pipe 12 is installed between the top of the dispensing pipe 11 and the funnel 6, and a quantitative dispensing assembly is installed inside the dispensing pipe 12 and the discharge pipe 11.
[0020] During operation, the pump is first started to extract the water inside the water storage shell 4 and transport it to the mixing box 10. The water addition value is monitored in real time by the liquid level sensor. When the water amount inside the mixing box 10 reaches the set value, the pump is closed to stop adding water. Then the lifting mechanism is started to transport the powder inside the medicine storage shell 4 to the top and automatically added to the funnel 6 through the guide pipe 7. The powder first enters the dispensing pipe 12 and is weighed by the quantitative feeding component. When the weight of the powder reaches the set value, it is discharged and enters the mixing box 10 through the feeding pipe 11 to complete the automatic quantitative addition of water and powder, thereby improving the work efficiency and the accuracy of the medicine. Then the stirring component is started to stir and mix the water and powder. After mixing evenly, the solenoid valve is opened to allow the prepared medicine to enter the medicine storage box 8 for storage.
[0021] The lifting mechanism includes a lifting shell 13 installed inside the medicine storage shell 2, a conveying screw 14 installed inside the lifting shell 13, and a servo motor 1 that drives the conveying screw 14. The servo motor 1 is installed at the bottom of the lifting shell 13. A feed port is opened at the bottom of one side of the lifting shell 13, and a discharge port is opened at the top of the other side. The guide pipe 7 is installed at the discharge port. The conveying screw 14 is driven by the servo motor 1, thereby conveying the powder to the top, and then the powder is automatically added to the funnel through the guide pipe.
[0022] The stirring assembly includes a servo motor 2 installed on the top of the mixing box 10, a stirring shaft connected to the output end of the servo motor 2, a plurality of stirring rods 15 installed on the outside of the stirring shaft, and a propeller 16 located below the stirring rod 15. The servo motor 2 drives the stirring shaft and the stirring rod 15 to rotate for automatic stirring and mixing. The propeller 16 can transport the medicine at the bottom to the top, making the mixing more uniform.
[0023] The quantitative unloading component includes a baffle 17 installed on the inner side of the feeding pipe and rotatably connected to it, an electric push rod and a gravity sensor installed below the baffle 17. The baffle 17 matches the feeding pipe 12 and is used to seal the feeding pipe 12. The electric push rod is installed on one side of the unloading pipe 11, and the output shaft end is connected to the bottom of the baffle 17. The gravity sensor is used to detect the weight of the powder above the baffle 17 in real time. When the setting is reached, a signal is sent to the control panel 5, and the electric push rod is started through the control panel 5 to drive the baffle 17 to rotate downward and open for unloading. It should be noted that a controller is installed inside the control panel 5. The controller can use an existing STM32 single-chip microcomputer to control the opening and closing of the electric push rod, pump body, servo motor 1, servo motor 2 and solenoid valve.
[0024] It should be noted that a slide groove is provided at the bottom of the baffle 17, and a rotating structure is provided inside the slide groove. The rotating structure is a slider installed in the slide groove and slidably connected to it. The output shaft end of the electric push rod is rotatably connected to the slider. This is the existing technology and will not be described in detail here.
[0025] The diameter of the batching pipe 12 is smaller than the diameter of the discharge pipe 11 to avoid clogging of the discharge pipe 11 during discharge.
[0026] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection.
