Description

TECHNICAL FIELD

[0001] The utility model relates to homogenizing equipment technical field, concretely is homogenizing equipment for liquid cosmetic production. BACKGROUND

[0002] In the production process of liquid cosmetics, homogenization is a crucial link. The purpose of homogenization is to uniformly mix various ingredients in cosmetic raw materials, ensuring stable product quality and consistent performance. Currently, the common liquid cosmetic homogenizing equipment on the market has some shortcomings. For example, the traditional stirring type homogenizing equipment has a single structure and movement mode of stirring paddle, which is difficult to fully homogenize liquid cosmetic raw materials of different viscosities, easily leading to product quality problems such as stratification and sedimentation. SUMMARY

[0003] The utility model mainly provides homogenizing equipment for liquid cosmetic production, solves the single structure and movement mode of stirring paddle of the traditional stirring type homogenizing equipment, which is difficult to fully homogenize liquid cosmetic raw materials of different viscosities, easily leading to product quality problems such as stratification and sedimentation.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme:

[0005] A homogenizing device for liquid cosmetic production includes a support frame and a fixed cavity for holding the liquid. The support frame is equipped with a first lifting mechanism and a second lifting mechanism. The first lifting mechanism has a high-shear mechanism, and the second lifting mechanism has a movable cavity. The movable cavity moves up and down within the fixed cavity via the second lifting mechanism. A shear gap exists between the outer wall of the movable cavity and the inner wall of the fixed cavity. Multiple first guide holes are formed on the side wall of the movable cavity, with the inner diameter of each guide hole being larger than its outer diameter. The first, second, and third lifting mechanisms can be any existing technology, as long as they can drive the corresponding components up and down and achieve the corresponding technical principle. The high-shear mechanism can be any existing technology, such as the stirring and homogenizing structure of a conventional stirring homogenizing mechanism, to stir and homogenize the liquid. The bottom of the fixed cavity has a discharge port for discharging the liquid, and a valve can be installed on the discharge port. In use, after adding various liquid materials that need to be homogenized into the fixed cavity, the first lifting mechanism drives the high-shear mechanism to descend into the fixed cavity. Then, the second lifting mechanism drives the movable cavity into the fixed cavity. The high-shear mechanism then stirs and homogenizes the liquid materials in the fixed cavity. At the same time, during the operation of the high-shear mechanism, the second lifting mechanism drives the movable cavity to move up and down in the fixed cavity. The relative up and down movement of the movable cavity in the fixed cavity causes the material to be subjected to constantly changing pressure between the two cavities. As the movable cavity approaches the fixed cavity, the material enters the shear gap from the first guide hole and the lower end of the movable cavity, thus subjecting the material to strong shear force. After the movable cavity moves away from the fixed cavity, the material returns to the fixed cavity from the shear gap and the first guide hole. Using the structure of this application: 1. It can shear the material in the fixed cavity through the high shear mechanism, thereby generating strong shearing and mixing in the horizontal direction. The second lifting mechanism can drive the movable cavity to reciprocate within the fixed cavity during the operation of the high shear mechanism. The material is subjected to constantly changing pressure between the fixed and movable cavities. When the movable cavity approaches the fixed cavity, the material is squeezed through the narrow shear gap and subjected to strong shearing force. When the movable cavity moves away from the fixed cavity, the pressure inside the cavity suddenly decreases, and the material generates turbulence under the pressure difference, further promoting mixing. This effectively overcomes the poor flowability of high-viscosity materials, effectively improving the efficiency of homogenization and mixing, and preventing product stratification. 2. The setting of the first guide hole can further accelerate the material entering the shear gap. The inner diameter of the first guide hole is larger than the outer diameter, which can further pressurize the material moving to the shear gap through the first guide hole when the movable cavity moves towards the fixed cavity, improving the shearing and homogenization effect.

[0006] Furthermore, the support is equipped with a third lifting mechanism, which has a cover for covering the upper opening of the fixed cavity. This structure allows the upper part of the fixed cavity to be shielded by the cover, thereby preventing excessive material splashing out.

[0007] Furthermore, the upper wall of the movable cavity is provided with multiple second guide holes, the lower diameter of which is larger than the upper diameter; an impact baffle is positioned above the upper wall of the movable cavity. In use, after the movable cavity is moved along the line, the material flows out from the second guide holes and impacts the impact baffle, then moves and mixes in the gap between the impact baffle and the upper wall of the movable cavity. This structure further enhances the mixing of the material through the guide holes.

[0008] Furthermore, an annular baffle is provided at the upper end of the fixed cavity, with the inner end of the annular baffle being lower than the outer end. This structure allows the upper position within the cavity to be fixed by the annular baffle, thereby preventing material from being ejected directly from above the shear gap due to excessive pressure during the movement of the movable cavity.

[0009] Furthermore, the fixed cavity is provided with a feeding section and a pressurizing section from top to bottom, with the diameter of the pressurizing section being smaller than that of the feeding section. With this structure, the shear gap between the moving cavity and the fixed cavity of the pressurizing section is small when the moving cavity enters the pressurizing section from top to bottom, achieving a high shearing effect. When the moving cavity moves upward into the feeding section, the shear gap between the moving cavity and the fixed cavity of the feeding section increases, allowing the material to return to the fixed cavity more effectively.

[0010] Beneficial effects: 1. The high-shear mechanism can shear the material in the fixed cavity, thereby generating strong shearing and mixing in the horizontal direction. The second lifting mechanism, during the operation of the high-shear mechanism, drives the movable cavity to reciprocate within the fixed cavity. The material is subjected to constantly changing pressure between the fixed and movable cavities. When the movable cavity approaches the fixed cavity, the material is squeezed through the narrow shear gap and subjected to strong shearing force. When the movable cavity moves away from the fixed cavity, the pressure inside the cavity suddenly decreases, and the material generates turbulence under the pressure difference, further promoting mixing. This effectively overcomes the poor flowability of high-viscosity materials, effectively improving homogenization and mixing efficiency and preventing product stratification. 2. The first guide hole further accelerates the material's entry into the shear gap. The inner diameter of the first guide hole is larger than the outer diameter, further pressurizing the material moving through the first guide hole to the shear gap as the movable cavity moves towards the fixed cavity, improving shearing and homogenization effects.

[0017] like Figure 1 , Figure 2 , Figure 3As shown, a homogenizing device for liquid cosmetic production includes a support 1 and a fixed cavity 2 for holding the liquid. The support 1 is equipped with a first lifting mechanism 3 and a second lifting mechanism 4. The first lifting mechanism 3 is equipped with a high-shear mechanism 5, and the second lifting mechanism 4 is equipped with a movable cavity 6. The movable cavity 6 moves vertically within the fixed cavity 2 under the action of the second lifting mechanism 4. The outer wall of the movable cavity 6 has a shear gap with the inner wall of the fixed cavity 2. Multiple first guide holes 7 are formed on the side wall of the movable cavity 6, with the inner diameter of each guide hole 7 being larger than its outer diameter. The bottom of the fixed cavity 2 has a discharge port for discharging material, and a valve can be installed on the discharge port. The support 1 is equipped with a third lifting mechanism 8, which has a cover 9 for covering the upper opening of the fixed cavity 2. The upper wall of the movable cavity 6 is provided with multiple second guide holes 10, the lower end diameter of the second guide holes 10 being larger than the upper end diameter; an impact baffle 11 is provided above the upper wall of the movable cavity 6. An annular baffle 12 is provided at the upper end of the fixed cavity 2, the inner end height of the annular baffle 12 being lower than the outer end height. Feeding is possible at the middle of the annular baffle 12. The fixed cavity 2 has a feeding section and a pressurizing section arranged from top to bottom, the diameter of the pressurizing section being smaller than the diameter of the feeding section. A first shaft gap is provided on the movable cavity 6 to accommodate the rotating shaft of the high-shear mechanism 5, and a second shaft gap is provided on the impact baffle 11 to accommodate the rotating shaft of the high-shear mechanism 5. A sealing ring 13 is provided within this second shaft gap. The sealing ring 13 rotates along with the impact baffle 11 as it moves up and down along the rotating shaft of the high-shear mechanism 5, thus achieving a seal. In use, after adding various liquid materials that need to be homogenized into the fixed cavity 2, the first lifting mechanism 3 drives the high-shear mechanism 5 to descend into the fixed cavity 2. Then, the second lifting mechanism 4 drives the movable cavity 6 into the fixed cavity 2. The high-shear mechanism 5 is then used to stir and homogenize the liquid materials in the fixed cavity 2. At the same time, during the operation of the high-shear mechanism 5, the second lifting mechanism 4 drives the movable cavity 6 to move up and down in the fixed cavity 2. The movable cavity 6 moves up and down relative to the fixed cavity 2, and the material is subjected to the constantly changing pressure between the two cavities. When the movable cavity 6 approaches the fixed cavity 2, the material will enter the shear gap from the first guide hole 7 and the lower end of the movable cavity 6, thus subjecting the material to strong shear force. Then, when the movable cavity 6 moves away from the fixed cavity 2, the material will return to the fixed cavity 2 from the shear gap and the first guide hole 7.Using the structure of this application: 1. The high-shear mechanism 5 can shear the material in the fixed cavity 2, thereby generating strong shearing and mixing in the horizontal direction. During the operation of the high-shear mechanism 5, the second lifting mechanism 4 can drive the movable cavity 6 to reciprocate within the fixed cavity 2. The material is subjected to constantly changing pressure between the fixed cavity 2 and the movable cavity 6. When the movable cavity 6 approaches the fixed cavity 2, the material is squeezed through a narrow shear gap and subjected to strong shearing force. When the movable cavity 6 moves away from the fixed cavity 2, the pressure inside the cavity suddenly decreases, and the material generates turbulence under the pressure difference, further promoting mixing. This effectively overcomes the poor flowability of high-viscosity materials, effectively improving the efficiency of homogenization and mixing, and preventing product stratification. 2. The first guide hole 7 further accelerates the material's entry into the shear gap. The inner diameter of the first guide hole 7 is larger than the outer diameter, further pressurizing the material moving through the first guide hole 7 to the shear gap when the movable cavity 6 moves towards the fixed cavity 2, improving the shearing and homogenization effect.
