Description

Technical Field

[0001] This utility model relates to the field of stirring and mixing technology, specifically to a stirring structure and stirring tank for preventing powder agglomeration. Background Technology

[0002] In the wave of modern cosmetics manufacturing, consumers' pursuit of product quality and personalization is rising. This trend has driven the continuous progress of cosmetics production processes and equipment technology. As a core component in the cosmetics production process, the technological innovation of cosmetic powder-water mixing equipment plays a vital role in improving product quality, accelerating production efficiency, and flexibly responding to diversified market demands.

[0003] Cosmetic powder-to-water mixing equipment is specifically designed for the efficient and uniform mixing of powder raw materials (including the core powder ingredients in cosmetics such as foundation and eyeshadow) with water or other liquid raw materials, aiming to produce cosmetic products with high stability. Its operating mechanism is deeply rooted in complex mixing theory, encompassing multiple mechanisms such as overall flow, convection mixing, and diffusion mixing. In the powder-to-water mixing process, the powder raw materials and solution are introduced into a mixing container, and then, with the aid of a precise mixing mechanism (such as a stirrer or rotor), they achieve full contact and fusion with water or other liquid raw materials. During this process, the interaction forces between powder particles and liquid molecules promote the material to achieve an ideal uniform dispersion state. However, given the significant density and viscosity differences between powder and water, the simple stirrer structure used in existing powder mixing equipment cannot disperse the powder during stirring. This leads to problems such as powder agglomeration, sedimentation, and localized concentration imbalances when handling such significantly different powders, directly resulting in poor mixing effects and affecting the final quality of the cosmetics.

[0004] Therefore, the inventors have proposed a stirring structure and a stirring tank to prevent powder agglomeration in order to solve the above-mentioned technical problems. Utility Model Content

[0005] One objective of this invention is to provide a stirring structure that prevents powder agglomeration, thereby solving the problem that existing water-mixing equipment cannot disperse powder, leading to powder agglomeration and sedimentation during stirring; the second objective is to provide a stirring tank.

[0006] On the one hand, in order to achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A stirring structure for preventing powder agglomeration includes a rotating shaft, a first stirring component, and a driving component. The first stirring component is connected to the rotating shaft, and the rotating shaft is connected to the driving component. The driving component drives the first stirring component to rotate through the rotating shaft.

[0008] The first stirring assembly includes a rotating head and at least two rotating blades, each of which is rotatably mounted on the rotating head. The rotating head is provided with a pushing member, which is used to change the angle of the rotating blades.

[0009] Furthermore, the pushing member includes a pushing plate and a plurality of support rods, one end of each support rod being hinged to one of the corresponding rotating fan blades, and the other end of the support rod being hinged to the pushing plate.

[0010] Furthermore, the pusher also includes a first connecting rod that passes through the rotating head and is slidably connected to the rotating head. The top of the first connecting rod is fixedly connected to the push plate, and the bottom of the first connecting rod is connected to the drive assembly.

[0011] According to the above technical solution, the pushing component consists of a pushing plate, several support rods, and a first connecting rod. One end of the support rod is hinged to the rotating fan blade, and the other end is hinged to the pushing plate, forming a flexible linkage structure. When the first connecting rod moves up and down under the drive of the driving component, it pushes or pulls the pushing plate, which in turn changes the angle of the rotating fan blade through the support rod. The reciprocating motion of the first connecting rod causes the pushing plate to move up and down continuously, which is transmitted to the rotating fan blade through the support rod, resulting in the real-time adjustment of the angle of the rotating fan blade. This dynamic angle change not only enhances the uniformity of mixing, but also further promotes the dispersion and mixing of powder through the constantly changing airflow direction. It realizes the combination of mechanical stirring and airflow dispersion during the mixing process, significantly improving the mixing efficiency and mixing quality, and avoiding the phenomenon of powder agglomeration and deposition.

[0012] Furthermore, the rotating shaft is a hollow structure with openings at both ends, and the first connecting rod is sleeved inside the rotating shaft, and the first connecting rod can slide up and down inside the rotating shaft.

[0013] Furthermore, a second stirring assembly is provided on the rotating shaft, the second stirring assembly being coaxially fixed on the rotating shaft and located below the first stirring assembly.

[0014] Furthermore, the second stirring assembly includes a cylinder and at least one stirring element, wherein each stirring element is arranged at intervals along the axial direction of the cylinder;

[0015] The stirring component includes a plurality of stirring fans, each of which is evenly installed on the outer periphery of the cylinder.

[0016] Furthermore, the drive assembly includes a drive housing, a drive motor and a drive unit disposed within the drive housing, a first drive shaft connected to the output shaft of the drive motor, the first drive shaft being rotatably connected inside the drive housing, and a drive bevel gear being coaxially fixedly disposed at the end of the first drive shaft;

[0017] The bottom of the rotating shaft extends into the drive housing and is coaxially fixed with a driven bevel gear, which meshes with the driving bevel gear.

[0018] Furthermore, the drive unit includes a support base, a second drive shaft, toothed rings symmetrically fixed on the support base, and a sleeve fixed on the support base. Gears are rotatably connected inside both toothed rings. The second drive shaft is used to drive the gears to rotate around the toothed rings. An eccentric rod is provided between the two gears, and a push rod is hinged on the eccentric rod.

[0019] A piston rod is slidably connected inside the sleeve, and the top of the push rod is hinged to the bottom of the piston rod;

[0020] The bottom of the first connecting rod extends into the drive housing and is fixedly connected to the top of the piston rod.

[0021] Furthermore, the second drive shaft is rotatably disposed within the drive housing, a first pulley is fixedly disposed on the first drive shaft, a second pulley is fixedly disposed on the second drive shaft, and a tension belt is tensioned between the first pulley and the second pulley.

[0022] According to the above technical solution, the drive assembly is the core of the stirring structure that prevents powder agglomeration. It consists of a drive motor and a drive unit inside the drive housing. The output shaft of the drive motor is connected to the first drive shaft. When the first drive shaft rotates, the driving bevel gear at its end meshes with the driven bevel gear at the bottom of the shaft, thereby driving the shaft to rotate. Simultaneously, the second drive shaft rotates inside the drive housing and is connected to the first drive shaft via a tension belt to achieve synchronous rotation. The second drive shaft drives the gear on the support to rotate around the gear ring, and the push rod connected between the gears via an eccentric rod swings accordingly. The top of the push rod is hinged to the piston rod inside the sleeve, so the piston rod slides up and down inside the sleeve. This sliding motion is transmitted to the first connecting rod extending into the drive housing through a fixed connection, thereby driving the rotating blade angle in the first stirring assembly to adjust in real time. The entire drive assembly is ingeniously designed, achieving efficient transmission of motor power and dynamic adjustment of the stirring assembly.

[0023] On the other hand, this application also proposes a mixing tank, including a tank body, a solution inlet pipe and a powder inlet pipe, wherein the solution inlet pipe and the powder inlet pipe are connected to the tank body, and a discharge pipe is provided at the bottom of the tank body, and a valve is installed on the discharge pipe; it also includes a stirring structure as described above to prevent powder agglomeration, wherein the stirring structure to prevent powder agglomeration is installed on the tank body.

[0024] According to the above technical solution, when the mixing tank is working, the solution and powder enter the tank through the solution inlet pipe and the powder inlet pipe, respectively. After the stirring structure that prevents powder agglomeration is started, the rotating shaft drives the first and second stirring components to rotate and mix the materials. After the mixing is completed, the valve on the discharge pipe is opened to discharge the uniformly mixed material from the tank.

[0025] The beneficial effects of this utility model are:

[0026] This invention, upon activation by the drive assembly, causes the rotating head of the first stirring assembly to rotate at high speed via a rotating shaft. At least two rotating blades mounted on the rotating head rotate accordingly. This not only mechanically stirs the powder entering the mixing tank, but more importantly, the high-speed rotating blades also generate airflow. This airflow strongly disperses the powder entering the mixing tank, effectively preventing agglomeration and sedimentation, and ensuring more uniform dispersion in the liquid. Simultaneously, the pusher on the rotating head can dynamically adjust the angle of the rotating blades, thereby changing the intensity and direction of the airflow, further enhancing the stirring effect. This not only improves stirring efficiency but also makes the stirring process more flexible and controllable, better adapting to changes in different powders and stirring requirements. By combining mechanical stirring and airflow dispersion, this invention effectively solves the technical problem of uneven mixing of powder and liquid.

The objectives and other advantages of this application may be realized and obtained through the detailed embodiments described below. Attached Figure Description

Detailed Implementation

[0037] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0039] This embodiment proposes a stirring structure and its stirring tank to prevent powder agglomeration, such as... Figures 1 to 8As shown, it includes a rotating shaft 4, a first stirring assembly 5 and a driving assembly 6. The first stirring assembly 5 is connected to the rotating shaft 4, and the rotating shaft 4 is connected to the driving assembly 6. The driving assembly 6 drives the first stirring assembly 5 to rotate through the rotating shaft 4.

[0040] like Figure 2 and Figure 3 As shown, the first stirring assembly 5 includes a rotating head 51 and at least two rotating blades 52. As an exemplary embodiment, there are four rotating blades 52, which are evenly distributed around the rotating head 51. Of course, it is understood that the number of rotating blades 52 is not limited to four, but can also be more than four. Each rotating blade 52 is movably mounted on the rotating head 51. Specifically, the rotating blade 52 can rotate at a certain angle on the rotating head 51. A pushing member 53 is provided on the rotating head 51, which is used to drive the rotating blades 52 to change their angle.

[0041] According to the above technical solution, after the drive component 6 is started, it drives the rotating head 51 of the first stirring component 5 to rotate at high speed through the rotating shaft 4. The multiple rotating blades 52 installed on the rotating head 51 rotate accordingly to mechanically stir the powder entering the mixing tank. More importantly, the high-speed rotating blades 52 can also generate airflow. This airflow has a strong blowing effect on the powder entering the mixing tank, which can effectively disperse the agglomerated or deposited powder and make it more evenly dispersed in the mixing tank. At the same time, the pusher 53 on the rotating head 51 can dynamically adjust the angle of the rotating blades 52, thereby continuously changing the airflow and further enhancing the stirring effect. This allows the stirring to better adapt to changes in different powders and stirring requirements. Combining mechanical stirring and airflow dispersion, the problem of powder agglomeration is effectively solved.

[0042] As a preferred embodiment, such as Figure 4 As shown, the pusher 53 includes a push plate 531 and a plurality of support rods 532. One end of each support rod 532 is hinged to a corresponding rotating fan blade 52, and the other end of each support rod 532 is hinged to the push plate 531. Preferably, there are four support rods 532. The top of each support rod 532 is hinged to the push plate 531, and the bottom of each support rod 532 is hinged to the corresponding rotating fan blade 52.

[0043] The pusher 53 also includes a first connecting rod 533, which passes through the rotating head 51 and is slidably connected to the rotating head 51. The top of the first connecting rod 533 is fixedly connected to the push plate 531, and the bottom of the first connecting rod 533 is connected to the drive assembly 6. The pusher 53 consists of a pusher plate 531, several support rods 532, and a first connecting rod 533. One end of the support rod 532 is hinged to the rotating fan blade 52, and the other end is hinged to the pusher plate 531, forming a flexible linkage structure. When the first connecting rod 533 moves up and down under the drive of the drive component 6, it pushes or pulls the pusher plate 531, which in turn drives the angle of the rotating fan blade 52 to change through the support rod 532. The reciprocating motion of the first connecting rod 533 causes the pusher plate 531 to move up and down continuously, which is transmitted to the rotating fan blade 52 through the support rod 532, resulting in the real-time adjustment of the angle of the rotating fan blade 52. This dynamic angle change not only enhances the uniformity of mixing, but also further promotes the dispersion and mixing of powder through the constantly changing airflow direction. It realizes the combination of mechanical mixing and airflow blowing during the mixing process, effectively blowing away agglomerated or deposited powder, and significantly improving the mixing efficiency and mixing quality.

[0044] In a preferred embodiment, the rotating shaft 4 is a hollow structure with openings at both ends. The first connecting rod 533 is sleeved inside the rotating shaft 4 and can slide up and down inside the rotating shaft 4. A second stirring assembly 7 is provided on the rotating shaft 4. The second stirring assembly 7 is coaxially fixed on the rotating shaft 4 and is located below the first stirring assembly 5. The second stirring assembly 7 includes a cylinder 71 and at least one stirring element 72. The stirring elements 72 are arranged at intervals along the axial direction of the cylinder 71. In this embodiment, there are two stirring elements 72, and the two stirring elements 72 are symmetrically arranged. The symmetrical arrangement of the stirring elements 72 can ensure that the powder is evenly distributed during the stirring process. The two stirring elements 72 work at the same time, which can form a stronger stirring force field, thereby accelerating the mixing and homogenization process of the material, helping to eliminate stirring dead zones and improve the stirring effect.

[0045] The mixing component 72 includes several mixing blades 721, each of which is evenly installed on the outer circumference of the cylinder 71. These mixing blades 721 are located on the outer circumference of the cylinder 71 and rotate with the rotation of the shaft 4. When the drive assembly 6 is started, the shaft 4 drives the first mixing assembly 5 and the second mixing assembly 7 to rotate simultaneously. The rotating blades 52 above the first mixing assembly 5 generate airflow during high-speed rotation, which disperses and initially mixes the powder. Meanwhile, the second mixing assembly 7 located below further mechanically mixes the material through its mixing blades 721, ensuring that the material is mixed in all directions within the mixing tank. This double-layer mixing design not only improves the mixing efficiency but also enhances the uniformity of the mixing, allowing the powder and liquid to mix more thoroughly. At the same time, since the mixing blades 721 of the second mixing assembly 7 are evenly installed on the outer circumference of the cylinder 71, they can generate a more uniform and stable mixing force, further improving the mixing quality.

[0046] As a preferred embodiment, such as Figure 5 As shown, the drive assembly 6 includes a drive housing 61, a drive motor 62 and a drive unit 63 disposed inside the drive housing 61. A first drive shaft 64 is connected to the output shaft of the drive motor 62. The first drive shaft 64 is rotatably connected inside the drive housing 61. A driving bevel gear 65 is coaxially fixedly disposed at the end (left end) of the first drive shaft 64. A driven bevel gear 41 is coaxially fixedly disposed at the bottom of the rotating shaft 4 inside the drive housing 61. The driven bevel gear 41 meshes with the driving bevel gear 65.

[0047] As a preferred embodiment, such as Figure 5 and Figure 6 As shown, the second drive shaft 632 is rotatably mounted inside the drive housing 61. A first pulley 641 is fixedly mounted on the first drive shaft 64, and a second pulley 642 is fixedly mounted on the second drive shaft 632. A tension belt 643 is tensioned between the first pulley 641 and the second pulley 642.

[0048] As a preferred embodiment, such as Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the drive unit 63 includes a support base 631, a second drive shaft 632, gear rings 633 symmetrically fixed on the support base 631, and a sleeve 634 fixed on the support base 631. Gears 635 are meshed in both gear rings 633, and the gears 635 can rotate within the gear rings 633. The second drive shaft 632 is used to drive the gears 635 to rotate around the gear rings 633. An eccentric rod 636 is provided between the two gears 635, and a push rod 637 is hinged to the eccentric rod 636. A piston column 638 is slidably connected inside the sleeve 634, and the top of the push rod 637 is hinged to the bottom of the piston column 638. The bottom of the first connecting rod 533 extends into the drive housing 61 and is fixedly connected to the top of the piston column 638.

[0049] According to the above technical solution, the drive assembly 6 is the core of the stirring structure that prevents powder agglomeration. It consists of a drive motor 62 and a drive unit 63 inside the drive housing 61. The output shaft of the drive motor 62 is connected to the first drive shaft 64. When the first drive shaft 64 rotates, the driving bevel gear 65 at its end meshes with the driven bevel gear 41 at the bottom of the rotating shaft 4, thereby driving the rotating shaft 4 to rotate. At the same time, the second drive shaft 632 rotates inside the drive housing 61 and is connected to the first drive shaft 64 through the tension belt 643 to achieve synchronous rotation. The second drive shaft 632 drives the gear 635 on the support base 631 to rotate around the gear ring 633. The push rod 637 connected between the gears 635 through the eccentric rod 636 swings accordingly. The top of the push rod 637 is hinged to the piston rod 638 in the sleeve 634. Therefore, the piston rod 638 slides up and down in the sleeve 634. This sliding motion is transmitted to the first connecting rod 533 extending into the drive housing 61 through a fixed connection, thereby driving the rotating fan blades 52 in the first stirring assembly 5 to adjust their angle in real time. The entire drive assembly 6 is ingeniously designed, realizing the efficient transmission of motor power and the dynamic adjustment of the stirring assembly.

[0050] On the other hand, this application also proposes a mixing tank, including a tank body 3, a solution inlet pipe 1 and a powder inlet pipe 2, the solution inlet pipe 1 and the powder inlet pipe 2 being connected to the tank body 3, and a discharge pipe 31 being provided at the bottom of the tank body 3, with a valve 32 installed on the discharge pipe 31; it also includes a stirring structure for preventing powder agglomeration as described above, the stirring structure for preventing powder agglomeration being installed on the tank body 3; when the mixing tank is working, the solution and powder enter the tank body 3 through the solution inlet pipe 1 and the powder inlet pipe 2 respectively, after the stirring structure for preventing powder agglomeration is started, the rotating shaft 4 drives the first stirring component 5 and the second stirring component 7 to rotate, mixing the powder, after the mixing is completed, the valve 32 on the discharge pipe 31 is opened, and the uniformly mixed material is discharged from the tank body 3.
