Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and more specifically, to a high-mixing-output planetary mixer. Background Technology

[0002] Planetary mixers are highly efficient mixing equipment widely used in industries such as chemical, pharmaceutical, and food processing. Their main feature is that the mixer not only rotates on its own axis but also undergoes planetary motion during operation, achieving thorough mixing of materials. This design allows planetary mixers to effectively handle various viscous and high-viscosity materials, making them particularly suitable for applications requiring efficient mixing, homogenization, and dispersion. Thanks to their efficient mixing effect, fast discharge speed, and adjustable speed, planetary mixers can flexibly meet the processing needs of different materials. However, traditional planetary mixers also have some problems in practical applications: on the one hand, there are certain dead zones in the mixing effect, leading to uneven mixing, especially when processing high-viscosity and high-solids-content materials; on the other hand, there is a significant amount of material residue at discharge, making cleaning difficult and increasing equipment maintenance costs. These problems, to some extent, affect production efficiency and the long-term use of the equipment. Utility Model Content

[0003] The purpose of this invention is to provide a planetary mixer with high mixing output to solve the problems mentioned in the background art.

[0004] A high-mixing-output planetary mixer includes a mixing tank. A motor frame is fixedly connected to the top of the mixing tank, and a motor is fixedly connected to the top of the motor frame. A coupling is fixedly connected to the output end of the motor. A first driving gear and a second driving gear are fixedly connected to the external end of the output end of the coupling. A mounting frame is fixedly connected to the output end of the coupling. Two sets of mixing components are rotatably connected to the lower part of the mounting frame. A first driven gear and a second driven gear are fixedly connected to the external top of the two sets of mixing components. A cleaning component is fixedly connected to the lower part of one end of the mounting frame.

[0005] Preferably, the cleaning assembly includes a connecting rod, the outer part of which is fixedly connected to the lower part of one end of the mounting frame, and the bottom end of the connecting rod is fixedly connected to a mounting plate. A scraper is provided inside the mounting plate, and the outer part of the scraper abuts against the inner wall of the mixing tank.

[0006] Preferably, the mounting plate has an internal mounting groove, and multiple springs are fixedly connected inside the mounting groove. The other end of each spring is fixedly connected to a limiting plate.

[0007] Preferably, the side of the limiting plate away from the spring is fixedly connected to the inner side of the scraper, and the outer side of the limiting plate is slidably connected to the inside of the mounting groove.

[0008] Preferably, an electric push rod is rotatably connected to the outside of the mixing tank, and a discharge baffle is fixedly connected to the output end of the electric push rod. A fixing rod is rotatably connected to the top of the discharge baffle, and the fixing rod is fixedly connected to the outside of the mixing tank.

[0009] Preferably, the mixing tank is provided with feed inlets on both sides of the top.

[0010] Preferably, the driving gear and the driven gear are connected by a chain.

[0011] Preferably, the stirring assembly includes a stirring shaft and a stirring paddle, the top of the stirring shaft is fixedly connected to either driven gear one or driven gear two, and the bottom of the stirring shaft extends into the interior of the stirring tank.

[0012] Compared with existing technologies, the advantages of this utility model are: 1) In this utility model, by setting a transmission structure with a single motor driving double active gears, and cooperating with the revolution of the mounting frame and the rotation of the stirring component to form a compound planetary motion trajectory, the material is simultaneously subjected to the circumferential shear force generated by the revolution and the radial stirring force generated by the rotation, which greatly improves the mixing uniformity of high viscosity and high solid content materials and solves the problems of mixing dead corners and insufficient mixing in traditional mixers.

[0013] 2) In this utility model, the cleaning component adopts a spring-buffered scraper design. The spring applies continuous pressure to the scraper through the limiting plate to ensure that the scraper is always in close contact with the inner wall of the mixing tank, and achieves 360-degree scraping without dead angles during the revolution of the mounting frame. At the same time, the scraper and the mounting plate are detachably connected, and the scraper can be replaced separately when it is worn, which reduces the equipment maintenance cost.

[0014] 3) In summary, by integrating a high-efficiency planetary stirring structure, an adaptive cleaning component, and an electrically controlled discharge system, this utility model not only improves the mixing efficiency and uniformity of materials, but also solves the problems of excessive material residue, difficult cleaning, and inconvenient maintenance in traditional equipment. It is suitable for mixing and processing materials ranging from low viscosity to high viscosity. Attached Figure Description

[0019] Reference Figure 5The mounting plate 15 has an internal mounting groove 16. Multiple springs 17 are fixedly connected inside the mounting groove 16. A limiting plate 18 is fixedly connected to the other end of the springs 17. The side of the limiting plate 18 away from the springs 17 is fixedly connected to the inside of the scraper 19. The outside of the limiting plate 18 is slidably connected to the inside of the mounting groove 16.

[0020] A cleaning component is fixedly connected to one end of the mounting bracket 20. This component includes a connecting rod 14, which is externally and fixedly connected to the inside of one end of the mounting bracket 20. A mounting plate 15 is fixedly connected to the bottom end of the mounting bracket 20, and a scraper 19 is provided inside the mounting plate 15. The scraper 19 contacts the inner wall of the mixing tank 1, and the material is stirred by the operation of the stirring component 13, ensuring thorough stirring of the material in the container. A mounting groove 16 is provided inside the mounting plate 15, and multiple springs 17 are fixedly connected within the groove. The other end of each spring 17 is connected to a limiting plate 18. The side of the limiting plate 18 away from the springs 17 is fixedly connected to the inner side of the scraper 19, and the outer side of the limiting plate 18 is slidably connected within the mounting groove 16, ensuring that the scraper 19 always remains in close contact with the inner wall of the mixing tank 1, effectively removing residual material during the stirring process.

[0021] Reference Figure 1 and Figure 2 An electric push rod 5 is rotatably connected to the outside of the mixing tank 1. A discharge baffle 7 is fixedly connected to the output end of the electric push rod 5. A fixing rod 6 is rotatably connected to the top of the discharge baffle 7. The fixing rod 6 is fixedly connected to the outside of the mixing tank 1.

[0022] Outside the mixing tank 1, an electric push rod 5 is rotatably connected, and its output end is fixedly connected to a discharge baffle 7. The top of the baffle 7 is rotatably connected to a fixing rod 6, which is fixedly connected to the outside of the mixing tank 1. Driven by the electric push rod 5, the discharge system can automatically open and close, ensuring that the material after mixing can be smoothly discharged.

[0023] Working principle of this utility model: The operator injects the materials to be mixed into the mixing tank 1 through the feed inlets 4 on both sides of the top of the mixing tank 1, and controls the feed rate according to the total amount of materials. The motor 2 is started, and the torque output by the motor 2 is synchronously transmitted to two parts through the coupling 9: one part of the torque drives the first drive gear 8 and the second drive gear 11 to rotate, and the two drive gears drive the driven gear 10 and the second driven gear 12 to rotate through the chain, which in turn drives the mixing shaft of the mixing assembly 13 to rotate at high speed. The mixing blades on the mixing shaft apply radial shear force and dispersing force to the materials. The upper blades tumble the lower materials upward, and the lower blades disperse the materials deposited at the bottom of the tank. Another portion of the torque directly drives the mounting frame 20 to slowly revolve around the axis of the mixing tank 1, causing the mixing component 13 to move circumferentially along the tank wall while rotating, forming a "planetary trajectory" to ensure that the mixing paddle can cover all areas inside the mixing tank 1 and avoid the formation of mixing dead zones.

[0024] During the revolution of the mounting frame 20, the cleaning component at one end moves synchronously: the connecting rod 14 drives the mounting plate 15 and the scraper 19 to slide along the circumference of the inner wall of the mixing tank 1, and the outer side of the scraper 19 is always in contact with the tank wall; when the scraper 19 encounters a small protrusion on the tank wall or experiences slight wear, the spring 17 in the mounting plate 15 will apply elastic pressure to the scraper 19 through the limiting plate 18, pushing the scraper 19 to adaptively adjust its position and maintain close contact with the tank wall, thereby scraping off the material adhering to the tank wall in real time, ensuring that all the material participates in the mixing, and reducing the amount of subsequent cleaning work.

[0025] Once the materials are mixed, turn off motor 2 and start the electric push rod 5 outside the mixing tank 1. The piston rod of the electric push rod 5 retracts, causing the discharge baffle 7 to rotate around the fixed rod 6 as the pivot, opening the discharge port at the bottom of the mixing tank 1. The materials are discharged from the discharge port under the action of gravity. If the material viscosity is high, motor 2 can be started briefly to gently push the material with the stirring paddle to assist in the discharge. After the discharge is completed, the piston rod of the electric push rod 5 extends, pushing the discharge baffle 7 to reset and close, completing one mixing and discharge cycle.
