Description

Technical Field

[0001] This invention relates to the field of stirring device technology, and specifically to a non-contact centrifugal stirring device. Background Technology

[0002] Mixing devices play a crucial role in modern industry, widely used in various fields, including pharmaceuticals, materials, and cosmetics / skincare. Their core function is to promote material mixing, reaction, and mass transfer, ensuring product stability. Pharmaceutical mixing is used in the synthesis of active pharmaceutical ingredients (APIs), the preparation of pharmaceutical solutions, and granulation. For example, in antibiotic fermentation, it evenly disperses microorganisms and nutrients to increase yield; in wet granulation, it helps binders and powders combine to form stable granules. Material mixing processes chemical raw materials, battery slurries, and architectural coatings. For instance, in the production of stone paint, it mixes colored sand and emulsions to prevent sedimentation; in concrete mixing, it ensures the full integration of aggregates and cement. Cosmetics / skincare mixing achieves oil-water emulsification in emulsions and creams, evenly dispersing fragrances and active ingredients. For example, in the production of toners, it blends water-soluble and oil-soluble substances to ensure a fine texture. The selection of a mixing device must match the characteristics of the materials and process requirements to improve production efficiency.

[0003] In the production of lip gloss products, the mixing process is the core step to ensure uniform texture and stability. Existing mixing equipment, in order to meet the three core engineering requirements of handling high-viscosity materials, large-scale production, and process stability, works by having a motor drive a sprocket tower via a transmission chain. The sprocket tower is connected to a planetary gearbox, which in turn drives a mixing paddle to mix the materials in the mixing tank. Such mixing structures are usually large and cannot be mass-produced for civilian use. Users cannot use this type of equipment to add different pigments to create their own custom lip glosses. There is no lightweight mixing equipment on the market that meets users' needs. Summary of the Invention

The base shell is fixedly disposed on the periphery of the base inner support, and the stirring mounting part is a stirring mounting column extending upward from the upper end surface of the base inner support.

[0009] The invention is further improved by including a main control board, and a main control mounting position that cooperates with the main control board is provided on the lower end face of the inner support of the base. The main control board is set in the main control mounting position, and wiring holes that cooperate with the stirring stator are provided on the inner support of the base.

[0010] The invention is further improved by including a magnetic encoder, which is set on the upper end face of the stirring mounting column, and an encoding magnet that cooperates with the magnetic encoder is set on the lower end face of the stirring plate. The main control board can read the rotation angle of the stirring support through the cooperation of the magnetic encoder and the encoding magnet.

[0011] The invention is further improved by providing a wiring channel in the stirring mounting column that works with a magnetic encoder, with the lower end of the wiring channel connected to the main control mounting position.

[0012] In a further improvement, the present invention includes a second rotary bearing in the stirring base, and a second rotary mounting position that mates with the second rotary bearing is provided on the inner wall of the base shell. The second rotary bearing is sleeved around the drive cylinder, and the second rotary bearing can prevent wear caused by rotation between the drive cylinder and the base shell.

[0013] The present invention is further improved in that the first magnet driving part is a plurality of first magnet slots arranged on the rotating drive disk, and a first magnet body is arranged in the first magnet slot. The plurality of first magnet slots are evenly arranged around the outer periphery of the rotating drive disk.

[0014] The invention is further improved in that the second magnet driving part is a plurality of second magnet slots arranged on the stirring base, and a second magnet body is arranged in the second magnet slot.

Through the cooperation of the mixing stator 3 and the mixing rotor 4, the mixing stator 3 drives the mixing support 2 to rotate. The cup holder assembly 5 revolves around the mixing mounting part through the mixing support 2. At the same time, under the magnetic coupling of the first magnet driving part 531 and the second magnet driving part 111, the cup holder assembly 5 rotates, thereby driving the various materials in the cup holder assembly 5 to tumble, realizing non-contact mixing, eliminating the traditional mixing paddle structure. At the same time, during the rotation of the mixing support 2, the cup holder assembly 5 is tilted, which reduces the probability of materials falling off the cup holder assembly 5 when the centrifugal force is generated by the rotation of the mixing support, realizing stable and efficient mixing, simplifying the mixing structure, and meeting the user's need for lightweight equipment.

[0019] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, the present invention discloses a non-contact centrifugal mixing device, comprising a mixing base 1 and a mixing support 2. The mixing base 1 is provided with a mixing mounting part 121, and a mixing stator 3 is fixedly sleeved on the mixing mounting part 121. The mixing support 2 includes a mixing disc 21 and a drive cylinder 22 arranged vertically. The drive cylinder 22 is sleeved around the mixing stator 3, and a mixing rotor 4 that cooperates with the mixing stator 3 is provided on the inner wall of the drive cylinder 22. At least one cup holder assembly 5 is rotatably provided on the mixing disc 21. The cup holder assembly 5 can be used to store the material to be mixed, and the cup holder assembly 5 is inclined towards the central axis of the mixing disc 21. A rotating drive disc 53 is provided on the cup holder assembly 5. A first magnet drive part 531 is provided around the rotating drive disc 53. A second magnet drive part 111 that cooperates with the first magnet drive part 531 is provided around the mixing base 1.

[0022] Through the cooperation of the stirring stator 3 and the stirring rotor 4, the stirring stator 3 drives the stirring support 2 to rotate, and the cup holder assembly 5 revolves around the stirring mounting part through the stirring support 2. At the same time, under the magnetic coupling of the first magnet driving part 531 and the second magnet driving part 111, the cup holder assembly 5 rotates, thereby driving the various materials in the cup holder assembly 5 to tumble, realizing contactless stirring, eliminating the traditional stirring paddle structure. At the same time, during the rotation of the stirring support 2, the cup holder assembly 5 is tilted, which reduces the probability of materials detaching from the cup holder assembly 5 when the stirring support rotates and generates centrifugal force, achieving stable and efficient stirring, simplifying the stirring structure, and meeting the user's needs for lightweight equipment.

[0023] The cup holder assembly 5 also includes a cup holder cylinder 51 and a cup holder connecting rod 52. The two ends of the cup holder connecting rod 52 are respectively fixed on the cup holder cylinder 51 and the rotating drive disk 53. The stirring disk 21 is provided with a rotating channel for the cup holder connecting rod 52. The rotating channel passes through the upper and lower surfaces of the stirring disk 21. The cup holder connecting rod 52 is disposed in the rotating channel. The cup holder cylinder 51 is disposed inside the stirring disk 21. The rotating drive disk 53 is disposed on the outside of the stirring disk 21.

[0024] The cup holder 51 can support the material while its rotation can stir the material, fully blending different materials to create a customized lip gloss for the user.

[0025] When in use, the cup holder is inserted into the cup holder cylinder 51. The shape of the cup holder matches the inside of the cup holder cylinder 51. After stirring, the cup holder can be easily removed for cleaning. A decorative outer shell should be added to the stirring device to enhance the appearance of the equipment.

[0026] The cup holder 51 has a rectangular shape, and the cup holder assembly 5 is set at an angle. When the stirring support 2 is not rotating, the material in the cup holder 51 gathers on the lower side of the cup holder 51 under the action of gravity. Under the action of centrifugal force, the material in the cup holder 51 will move from the lower side of the cup holder 51 to the upper side of the cup holder 51 and tumble continuously. The side wall of the cup holder 51 blocks the material, reducing the probability that the material in the cup holder 51 will be thrown out of the cup holder 51.

[0027] A first rotary bearing 6 is fixedly installed inside the rotating channel, and the first rotary bearing 6 is sleeved on the cup holder connecting rod 52.

[0028] The first rotary bearing 6 prevents wear caused by the rotation between the cup holder connecting rod 52 and the rotating channel.

[0029] The mixing base 1 includes a base shell 11 and a base inner support 12. The base shell 11 is fixedly installed on the periphery of the base inner support 12. The mixing mounting part 121 is a mixing mounting column that extends upward from the upper end of the base inner support 12.

[0030] The non-contact centrifugal mixing device also includes a main control board 7. The lower end face of the inner support 12 of the base is provided with a main control mounting position that cooperates with the main control board 7. The main control board 7 is set in the main control mounting position. The inner support 12 of the base is provided with a wiring hole 122 that cooperates with the mixing stator 3.

[0031] The wiring hole 122 facilitates wiring of the stirring stator 3.

[0032] The non-contact centrifugal mixing device also includes a magnetic encoder 8, which is set on the upper end face of the mixing mounting column, and an encoding magnet 9 that cooperates with the magnetic encoder 8 is set on the lower end face of the mixing plate 21.

[0033] The main control board 7 can read the rotation angle of the stirring bracket 2 through the magnetic encoder 8 and the encoding magnet 9, so that it can be rotated to a specified angle for material receiving.

[0034] The mixing mounting column is provided with a wiring channel 1211 that cooperates with the magnetic encoder 8, and the lower end of the wiring channel 1211 is connected to the main control mounting position.

[0035] The cable routing channel 1211 facilitates cable routing while protecting the cables.

[0036] The stirring base 1 is also provided with a second rotary bearing 10. The inner wall of the base shell 11 is provided with a second rotary mounting position that cooperates with the second rotary bearing 10, and the second rotary bearing 10 is sleeved around the drive cylinder 22.

[0037] The second rotary bearing 10 prevents wear caused by rotation between the drive cylinder 22 and the base housing 11.

[0038] The number of second rotary bearings 10 is two.

[0039] The first magnet driving part 531 consists of a plurality of first magnet slots disposed on the rotating drive disk 53. A first magnet body is disposed in the first magnet slot, and the plurality of first magnet slots are evenly arranged around the outer periphery of the rotating drive disk 53.

[0040] By setting up multiple first magnet bodies, a magnetic driving effect can be achieved, while avoiding the need to set up a whole magnetic ring, which would increase the weight of the stirring device.

[0041] The second magnet drive unit 111 consists of multiple second magnet slots disposed on the stirring base 1. A second magnet body is disposed inside each second magnet slot, and the multiple second magnet slots are evenly arranged around the outer perimeter of the stirring base 1.

[0042] By setting multiple second magnet bodies, they can stably cooperate with multiple first magnets to stably drive the rotating drive disk 53 to rotate, achieving a magnetic driving effect while avoiding the need to set up a whole magnetic ring to increase the weight of the stirring device.

[0043] Both the mixing base 1 and the mixing bracket 2 are made of plastic, which can further reduce the weight of the mixing device and achieve lightweight design.

[0044] As can be seen from the above, the beneficial effects of the present invention are: by adopting its structure, it can effectively solve the problem that the existing stirring devices are too large to be used in civilian applications. Through the cooperation of the stirring stator 3 and the stirring rotor 4, the stirring stator 3 drives the stirring support 2 to rotate, and the cup holder assembly 5 revolves around the stirring mounting part through the stirring support 2. At the same time, under the magnetic coupling of the first magnet driving part 531 and the second magnet driving part 111, the cup holder assembly 5 rotates, thereby driving the various materials in the cup holder assembly 5 to tumble, realizing contactless stirring, eliminating the traditional stirring paddle structure. At the same time, during the rotation of the stirring support 2, the cup holder assembly 5 is tilted, which reduces the probability of materials detaching from the cup holder assembly 5 when the stirring support rotates and generates centrifugal force, realizing stable and efficient stirring, simplifying the stirring structure, and meeting the user's need for lightweight equipment.

The scope of the present invention includes, but is not limited to, these specific embodiments. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
