Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a magnetically driven self-rotating and revolution-type mixer. Background Technology

[0002] Currently, self-rotating and revolution-rotating mixers on the domestic market can simultaneously achieve uniform dispersion and defoaming of materials, with a wide range of applications covering polymers, nanomaterials, cosmetics, inks, solder paste, adhesives, and many other fields. The transmission methods of these devices are mainly divided into belt pulley drive and gear drive. The basic structure includes a motor, a transmission system (belt pulley or gear), a frame, and a material container. The operating principle is as follows: After the equipment starts, the motor drives the revolution while simultaneously driving the material container to rotate via the belt pulley or gear transmission system, ultimately achieving mixing of the materials within the container.

[0003] However, the two traditional transmission systems mentioned above share many common drawbacks, as follows: Unable to work continuously for long periods: When the equipment is running continuously, the transmission components generate intense friction due to high-speed rotation, which releases a lot of heat. This causes the temperature of the transmission components to exceed their own thermal deformation temperature, resulting in damage to the transmission components in a short period of time. Therefore, the equipment can only work intermittently for short periods of time, which is difficult to meet the needs of scenarios that require long-term continuous operation. Short equipment lifespan and high operating costs: Even with short-term intermittent operation, the components of the transmission system will still show significant wear after a period of use; when the wear reaches a certain level, the transmission system cannot be repaired and must be replaced entirely, which not only causes inconvenience to users but also significantly increases operating costs. High operating noise: During the transmission process, the friction between the transmission components will generate high-frequency noise, resulting in a noisy working environment and affecting the operator's work experience; Overload can damage core components: When equipment encounters an overload (such as a material container being overloaded with material), it will accelerate the wear of transmission components such as pulleys or gears, and may even cause core components such as motors to be damaged or burned out due to overload. Poor dust and water resistance: Dust and moisture can easily seep into the gaps of pulleys or gear drives, directly affecting the operating efficiency of the transmission system and shortening the service life of the equipment. Cumbersome maintenance: In order to ensure transmission efficiency and equipment life, the transmission system needs to be lubricated with grease or lubricating oil regularly, which increases the workload and cost of manual maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically driven self-rotating and revolution-type mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetic drive type self-rotating and revolution-rotating mixer, comprising a self-rotating motor, a revolution-rotating motor, a frame, and a material container, wherein the self-rotating motor, the revolution-rotating motor, the frame, and the material container are arranged sequentially from bottom to top; The output end of the self-rotating motor is connected to a self-rotating drive shaft via a coupling. The orbital motor is a hollow shaft motor, and the orbital drive shaft at the output end of the orbital motor has a hollow structure. The frame is fixedly connected to the end of the orbital drive shaft. The self-rotating drive shaft movably passes through the orbital drive shaft and the frame and is fixedly connected to a driving magnetic wheel. One end of the frame is rotatably inserted with a rotating shaft. A material container is fixed to the top of the rotating shaft, and a driven magnetic wheel is fixed to the bottom of the material container. The driven magnetic wheel is sleeved on the shaft wall of the rotating shaft and is adapted to the driving magnetic wheel.

[0006] Preferably, the outer ring of the active magnetic wheel is N-grade, and the inner ring is S-grade.

[0007] Preferably, the outer ring of the driven magnetic wheel is of class S and the inner ring is of class N.

[0008] Preferably, a gap is provided between the active magnetic wheel and the driven magnetic wheel.

[0009] Preferably, both the self-rotating drive shaft and the rotating shaft are rotatably connected to the frame via bearings.

[0010] Compared with the prior art, the beneficial effects of this utility model are: Supports long-term continuous operation: The non-contact magnetic transmission eliminates the problem of frictional heat generation between transmission components. The temperature of the transmission components will never exceed their own thermal deformation temperature, and the equipment can stably achieve long-term continuous operation, fully meeting the usage requirements of high-load scenarios. Extending equipment life and reducing costs: There is no physical contact between the transmission components (driving magnetic wheel and driven magnetic wheel), so there is no wear and tear. The entire equipment does not need to be replaced due to damage to the transmission components, which greatly extends the service life of the equipment and significantly reduces the user's use and maintenance costs. Achieving silent operation: By eliminating mechanical friction between transmission components, only the motor generates slight noise during equipment operation, achieving an overall silent effect and effectively improving the working environment for operators; Equipped with automatic overload protection: When the equipment encounters an overload (such as excessive material), the magnetic force cannot maintain the synchronous rotation of the active and driven magnetic wheels, resulting in slippage. This slippage mechanism is similar to an "automatic overload protection device," which can effectively prevent damage to core components such as motors due to overload. Excellent dust and water resistance: The magnetic drive is a non-contact structure with no physical gaps between the transmission components (only air gaps exist). Dust and moisture cannot penetrate into the transmission system, and the equipment can work stably and continuously in humid and dusty environments, ensuring operating efficiency and lifespan. No need for regular lubrication: Since there is no physical friction between the transmission components, there is no need to add lubricating oil or grease to maintain transmission efficiency, completely eliminating the maintenance steps of regular lubrication, reducing labor costs and maintenance complexity.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4 The present invention provides the following technical solution: a magnetic drive type self-rotation and revolution mixer, including a self-rotation motor 1, a revolution motor 2, a frame 5 and a material container 9, wherein the self-rotation motor 1, the revolution motor 2, the frame 5 and the material container 9 are arranged in order from bottom to top; The output end of the self-rotating motor 1 is connected to the self-rotating drive shaft 3 via a coupling. The revolution motor 2 is a hollow shaft motor. The revolution drive shaft 4 at the output end of the revolution motor 2 is a hollow structure. The frame 5 is fixedly connected to the end of the revolution drive shaft 4. The self-rotating drive shaft 3 moves through the revolution drive shaft 4 and the frame 5 and is fixedly connected to the driving magnetic wheel 7. One end of the frame 5 is rotatably inserted with a rotating shaft 8. A material container 9 is fixed to the top of the rotating shaft 8. A driven magnetic wheel 10 is fixed to the bottom of the material container 9. The driven magnetic wheel 10 is sleeved on the shaft wall of the rotating shaft 8 and is adapted to the driving magnetic wheel 7.

[0015] The outer ring of the driving magnetic wheel 7 is N-grade, and the inner ring is S-grade. The outer ring of the driven magnetic wheel 10 is S-grade, and the inner ring is N-grade. A gap is provided between the driving magnetic wheel 7 and the driven magnetic wheel 10, which is a non-contact type and can avoid mutual friction. Both the self-rotation drive shaft 3 and the rotating shaft 8 are rotatably connected to the frame 5 through bearings 6, which can avoid friction and wear between the self-rotation drive shaft 3 and the rotating shaft 8 when rotating relative to the frame 5.

[0016] Specifically, when using this utility model: I. The methods by which revolution and rotation are realized 1. The revolution of material container 9 is realized. The revolution effect of the material container 9 is transmitted through the following path: After the revolution motor 2 starts, the revolution drive shaft 4 at its output end rotates synchronously, thereby driving the frame 5 (fixed at the end of the revolution drive shaft 4) to follow the revolution; during the revolution, the frame 5 drives the material container 9 connected to it through the rotating shaft 8, and finally realizes the revolution movement of the material container 9.

[0017] 2. The rotation of material container 9 is achieved. The rotational power of the material container 9 is transmitted through magnetic transmission. The specific path is as follows: After the rotation motor 1 starts, it drives the rotation transmission shaft 3 to rotate through the coupling; the active magnetic wheel 7 at the top of the rotation transmission shaft 3 rotates synchronously with the shaft; since the active magnetic wheel 7 (outer ring N-class, inner ring S-class) is compatible with the driven magnetic wheel 10 (outer ring S-class, inner ring N-class) at the bottom of the material container 9, and a gap is reserved between the two (non-contact), the active magnetic wheel 7 drives the driven magnetic wheel 10 to rotate through the magnetic field force; the driven magnetic wheel 10 is sleeved on the shaft wall of the rotating shaft 8, thereby driving the rotating shaft 8 and the material container 9 at the top to complete the rotational motion.

[0018] II. Equipment Operation and Mixing Effect After the equipment is started, the revolution motor 2 and the rotation motor 1 run synchronously, and the material container 9 simultaneously achieves "revolution + rotation" under the coordinated action of the two motors: The revolution motion generates centrifugal force, which can push air bubbles in the material to the edge of the container and squeeze them to burst (i.e., defoaming effect). The rotational motion causes convection and agitation of the materials inside the container, breaking up agglomerated particles or uneven components (i.e., dispersion effect). The combination of the two allows the materials in the material container 9 to undergo degassing and mixing simultaneously, ultimately achieving efficient and uniform mixing.

[0019] III. Core Technological Advantages 1. Supports stable operation over long periods, reducing usage costs. In this transmission system, the revolution motor 2 and the rotation motor 1 are driven independently and do not interfere with each other. The active magnetic wheel 7 and the driven magnetic wheel 10 are in a non-contact engagement. This eliminates the frictional heat generation problem of traditional transmission components (avoiding the temperature of transmission components exceeding the thermal deformation temperature), ensuring long-term continuous operation of the equipment. It also eliminates wear and tear on transmission components, significantly extending the overall service life of the equipment and reducing the user's replacement and maintenance costs.

[0020] 2. Quiet operation, optimizing the working environment Since the active magnetic wheel 7 and the driven magnetic wheel 10 have no physical contact, no high-frequency noise will be generated due to friction of the transmission components during operation. Only the self-rotating motor 1 and the revolution motor 2 make a slight noise during operation, achieving overall silent operation and effectively improving the working environment of the operators.

[0021] 3. Automatic overload protection to prevent component damage. When the equipment encounters an overload (such as excessive material loading in the material container 9 or abnormally high material viscosity), the magnetic force between the active magnetic wheel 7 and the driven magnetic wheel 10 cannot maintain their synchronous rotation, resulting in a "slippage" phenomenon. This slippage mechanism is similar to an "automatic overload protection device," which can directly cut off the power transmission of the magnetic drive to prevent core components such as the self-rotating motor 1 and the revolution motor 2 from being damaged or burned due to overload.

[0022] 4. Dustproof and waterproof, suitable for harsh environments The non-contact structure of the active magnetic wheel 7 and the driven magnetic wheel 10 eliminates the physical gaps of traditional belt pulley / gear transmissions, effectively preventing dust and moisture from penetrating into the transmission system. Therefore, the equipment can operate continuously and stably in humid and dusty industrial environments (such as fine chemical workshops and daily chemical production environments), ensuring that work efficiency and equipment lifespan are not affected by the environment.

[0023] 5. No lubrication required, simplifying operation. The magnetic drive between the driving magnetic wheel 7 and the driven magnetic wheel 10 does not rely on a lubricating medium. Therefore, there is no need to add lubricating oil or grease to the transmission system regularly, completely eliminating the lubrication maintenance steps and greatly reducing the labor cost and operational complexity of equipment maintenance.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
