Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a planetary mixer with an automatic cleaning function. Background Art

[0002] A stirring device utilizes various mixing device structures to generate relative motion between powder materials, continuously changing their relative positions and overcoming the tendency for materials to stratify due to differences in the materials. Publication No. CN213556661UU discloses a planetary mixer comprising a mixing drum with a cover plate, a transmission assembly disposed on the cover plate, and a stirring assembly disposed within the mixing drum. The drive assembly comprises a reduction motor, a sun gear, planetary gears, and a ring gear. The sun gear is located at the center of the cover plate and connected to the output end of the reduction motor. The planetary gears mesh with the sun gear and the ring gear, respectively. The stirring assembly comprises a first stirring paddle connected to the sun gear and a second stirring paddle connected to the planetary gear. Both the first stirring paddle and the second stirring paddle are provided with multiple layers of blades, and the blades of the first stirring paddle and the second stirring paddle are staggered in the axial direction. The blades of the first stirring paddle include a first pitched paddle with an upwardly inclined upper portion and a second pitched paddle with a downwardly inclined lower portion. The blades of the second stirring paddle include a third pitched paddle with a downwardly inclined upper portion and a fourth pitched paddle with an upwardly inclined lower portion. This utility model has the advantages of excellent stirring and mixing effects and no dead angles in stirring.

An observation window 11 is embedded in the surface of the mixing barrel 1, and the observation window 11 is made of transparent glass. The raw materials in the mixing barrel 1 can be observed here. A sealing ring 16 is provided between the mixing barrel 1 and the barrel cover 2. The sealing ring 16 is made of rubber, which can improve the sealing effect between the barrel cover 2 and the mixing barrel 1. A discharge pipe 19 is fixedly connected to the bottom of the mixing barrel 1, and a valve 20 is fixedly connected to the surface of the discharge pipe 19. The material in the mixing barrel 1 can be discharged through the discharge pipe 19, and the valve 20 can control the speed and volume of the material outflow.

[0035] Example 2

[0036] See also Figure 1-3 The surface of the mixing barrel 1 is fixedly connected with a fixing block 12, and the internal thread of the fixing block 12 is connected with a screw 13, and the surface of the screw 13 is rotatably connected with a blocking block 15, and the bottom of the screw 13 is fixedly connected with an adjusting knob 14, and the blocking block 15 is in contact with the surface of the barrel cover 2, which makes it convenient to disassemble and assemble the mixing barrel 1 and the barrel cover 2, making the installation and disassembly of the barrel cover 2 more convenient and without the aid of tools, thereby improving the convenience of maintaining or replacing the workpiece in the mixing barrel 1 in the later stage.

[0037] Working principle: During use, first add the raw materials into the mixing barrel 1 through the funnel 18. When the raw materials in the mixing barrel 1 are stirred, start the motor 3. The output end of the motor 3 drives the cylindrical rod 4 to rotate. The rotation of the cylindrical rod 4 drives the stirring rod 5 and the connecting rod 6 to rotate at the same time. The scraper 7 is always pressed against the inner wall of the mixing barrel 1 under the action of the slider 9 pushed by the elastic force of the spring 10 in the chute 8. Then the scraper 7 rotates with the stirring rod 5 to scrape off the raw materials attached to the inner wall of the mixing barrel 1, so that the scraped raw materials can continue to participate in the stirring and mixing process. During operation, the stirring condition of the raw materials in the mixing barrel 1 can be observed through the observation window 11. The sealing ring 16 can improve the sealing effect between the mixing barrel 1 and the barrel cover 2. When the raw materials are stirred, the valve 20 on the discharge pipe 19 is opened to discharge the stirred raw materials through the discharge pipe 19. After the raw materials are discharged from the mixing barrel 1, the motor 3 is started again so that the scraper 7 scrapes off the raw materials attached to the inner wall of the mixing barrel 1 and discharges them through the discharge pipe 19. Then, the water valve at the other end of the water pipe 22 is opened, and the water in the water pipe 22 enters the connecting pipe seat 23 and is sprayed through the spray head 24. The mixing drum 1 is sprinkled with water, and then the inner wall of the mixing drum 1 is cleaned with the cooperation of the scraper 7 and the raw materials adhering to the mixing are flushed, so that the raw materials adhering to the inner wall of the mixing drum 1 are scraped off to avoid waste of raw materials. At the same time, the inner wall of the mixing drum 1 can be automatically cleaned to keep the inside of the mixing drum 1 clean and tidy after use, so as to avoid affecting the next use of the mixing drum 1 and the mixing and mixing of different materials. When the workpiece in the mixing drum 1 needs to be maintained or replaced after long-term use of the device, first turn the adjustment knob 14 to adjust the The knob 14 drives the screw 13 to rotate inside the fixed block 12 and pushes the block 15 to move toward each other. When the block 15 is out of the slot 17, the block 15 is rotated to move the block 15 away from the top of the barrel cover 2. Then the barrel cover 2 is taken out together with the workpiece in the mixing barrel 1. Then the stirring rod 5 or the scraper 7 can be inspected or maintained. This makes it easy to disassemble and assemble the mixing barrel 1 and the barrel cover 2, making the installation and disassembly of the barrel cover 2 more convenient and without the need for tools, thereby improving the convenience of maintaining or replacing the workpiece in the mixing barrel 1 in the later stage.
