Description

Technical Field

[0001] This invention relates to the field of cosmetic processing technology, specifically to an emulsification device and method for processing liquid foundation. Background Technology

[0002] As a core product in daily beauty makeup, the quality of foundation's emulsification process directly determines the product's texture, sensory quality, and shelf-life stability. In the modern cosmetics industry, foundation formulations are becoming increasingly complex and diverse, incorporating not only basic aqueous and oil phase components but also bioactive factors, functional powder fillers, and special additives. These components exhibit significant differences in polarity, particle size distribution, and rheological properties, posing stringent requirements for precise control of the temperature field, flow field uniformity, and energy input methods during the emulsification process. In foundation liquid production equipment, the stirring and emulsification system is the core unit that determines the success or failure of the process, and the accuracy of its speed regulation directly affects the emulsification effect at each stage. A typical industrial emulsification process includes three key stages: premixing, coarse emulsification, and fine emulsification. The premixing stage requires laminar flow stirring at low speed (30-200 rpm) to ensure initial dispersion of materials and suppress bubble entrainment. The coarse emulsification stage requires high-speed shearing (800-1200 rpm) to break down and reorganize the two-phase interface. The fine emulsification stage requires a stable speed of 400-600 rpm to maintain the dynamic balance of the emulsion system. However, traditional emulsification equipment generally adopts a speed regulation method of direct start-stop motor. From an equipment maintenance perspective, frequent start-stop cycles cause periodic thermal stress in the motor windings, accelerating the aging process of insulation materials. At the same time, the bearing system is subjected to instantaneous impact loads, thereby reducing the lifespan of the motor and bearings and increasing equipment operation and maintenance costs and the risk of unplanned downtime. More importantly, abrupt changes in stirring torque can trigger an unsteady flow field within the reactor, causing micron-sized powders to settle due to gravity and resulting in dispersed particle size distribution in the oil phase droplets. For high-end products containing nanoscale functional fillers or heat-sensitive bioactive ingredients, this unsteady stirring process can easily lead to localized overheating, causing the active ingredients to deactivate and denature, ultimately resulting in quality problems such as rough paste and uneven color.

[0003] Therefore, developing new emulsification equipment and processes with smooth speed adjustment and excellent operational stability has become a key direction for breaking through the industry's technological bottlenecks. Summary of the Invention

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] Example In foundation production equipment, especially large-capacity equipment, the stirring and emulsification system is the core unit that determines the success or failure of the process, and the accuracy of its speed regulation directly affects the emulsification effect at each stage. A typical industrial emulsification process includes three key stages: premixing, coarse emulsification, and fine emulsification. The premixing stage requires laminar flow stirring at low speed (30-200 rpm) to ensure initial dispersion of materials and suppress bubble entrainment. The coarse emulsification stage requires high-speed shearing (800-1200 rpm) to break down and reorganize the two-phase interface. The fine emulsification stage requires a stable speed of 400-600 rpm to maintain the dynamic balance of the emulsion system. However, traditional emulsification equipment generally adopts a speed regulation method of direct start-stop motor.

[0022] From the perspective of equipment maintenance, frequent start-stop cycles cause periodic thermal stress in the motor windings, accelerating the aging process of insulation materials. At the same time, the bearing system is subjected to instantaneous impact loads. According to industry statistics, the average lifespan of motors in this type of equipment is shortened by 30%-40% compared to normal operating conditions, which significantly increases equipment operation and maintenance costs and the risk of unplanned downtime. More importantly, abrupt changes in stirring torque can trigger an unsteady flow field within the reactor, causing micron-sized powders to settle due to gravity and resulting in dispersed particle size distribution in the oil phase droplets. For high-end products containing nanoscale functional fillers or heat-sensitive bioactive ingredients, this unsteady stirring process can easily lead to localized overheating, causing the active ingredients to deactivate and denature, ultimately resulting in quality problems such as rough paste and uneven color.

[0023] Based on the above issues, please refer to Figures 1-6 An emulsification device for foundation liquid processing includes a fixed cylinder 1 located inside a tank 26, a stirring motor 27 fixed to the bottom of the tank 26 with its output end located inside the fixed cylinder 1, an isolation block 4 rotatably connected to the end of the fixed cylinder 1 and driven to rotate by the output rod 33 of the stirring motor 27, and several stirring blades 2 rotatably connected to the isolation block 4. A first helical gear 17 is rotatably connected inside the isolation block 4, and a driving cavity 31 is provided on the isolation block 4. An angle motor 3 for driving the rotation of the first helical gear 17 is fixedly connected to the driving cavity 31. Each stirring blade 2 has a second helical gear 18 fixedly connected to one end inside the isolation block 4, which meshes with the first helical gear 17. Therefore, when the angle motor 3 is started, the first gear 14, the second gear 15, and the first helical gear 17 will rotate, thereby driving the second helical gear 18 to rotate, and thus realizing the rotation of the stirring blades 2, thereby realizing the angle adjustment of the stirring blades 2. This solves the technical problem that the angle of the traditional stirring blades 2 is not adjustable, and can adjust the angle of the stirring blades 2 according to the needs of different emulsification stages, thereby adjusting the stirring capacity, which is similar to the effect achieved by adjusting the rotation speed. Furthermore, the output rod 33 of the stirring motor 27 drives the isolation block 4 to rotate through the speed change mechanism. The speed change mechanism is connected to the output end of the angle motor 3 through the adjustment mechanism. The angle motor 3 adjusts the transmission ratio of the speed change mechanism while adjusting the angle of the stirring blade 2. Therefore, this invention combines the speed and angle adjustment of the stirring blade 2 to achieve gradual adjustment of the stirring capacity of the stirring emulsification system during the three stages of premixing, coarse emulsification, and fine emulsification, and to achieve gradual control of the speed. This eliminates the problem of reduced motor life caused by frequent start-stop cycles. At the same time, it also solves the problem that a sudden change in stirring torque can cause an unsteady flow field in the reactor, resulting in the gravity sedimentation of micron-sized powders and the dispersion of oil droplet particle size.

[0024] Existing speed-changing mechanisms lack a stable support structure and a precise transmission ratio adjustment unit, leading to vibrations during speed transmission, affecting emulsification uniformity, and failing to meet the precise speed requirements of complex foundation formulas. Therefore, in one embodiment of the present invention, a support plate 34 located inside the isolation block 4 is provided on the fixed cylinder 1. The speed-changing mechanism includes a rotating shaft 7 rotatably connected to the support plate 34. The output rod 33 of the stirring motor 27 is connected to the rotating shaft 7 via a synchronous belt drive assembly 16. A support frame 12 is fixedly connected inside the isolation block 4, and the end of the support frame 12 is connected to the rotating shaft 7 via a stepless speed regulation assembly. The end connection allows the angle motor 3 to adjust the transmission ratio of the continuously variable speed control component via an adjustment mechanism, thereby adjusting the transmission ratio of the speed change mechanism. The support plate 34 and support frame 12 provide stable support for the speed change mechanism, while the synchronous belt drive component 16 ensures stable power transmission. The continuously variable speed control component, as the core adjustment unit, precisely changes the transmission ratio under the action of the adjustment mechanism. This solves the technical problems of unstable support and inaccurate transmission ratio adjustment in the speed change mechanism, improves the stability and adjustment accuracy of speed transmission, provides a reliable structural foundation for subsequent continuously variable speed control, and ensures precise speed control at different emulsification stages.

[0025] Traditional speed-changing mechanisms often employ stepped speed changes, resulting in discontinuous transmission ratio adjustments and an inability to achieve smooth speed switching. This can easily lead to flow field fluctuations, causing micron-sized powders to settle and oil droplets to disperse. Therefore, in one embodiment of the present invention, the rotating shaft 7 has a blind hole inside. The stepless speed-regulating assembly includes a first inclined cone 5 fixed to the rotating shaft 7, a second inclined cone 6 slidably connected to the rotating shaft 7 via internal and external gear rings, a first tension spring 19 with one end fixed to the bottom of the blind hole and the other end fixed to the second inclined cone 6, a third inclined cone 9 fixed to the end of the support frame 12 and rotatably connected to the end of the fixed cylinder 1, and a fourth inclined cone 10 slidably connected to the support frame 12 via internal and external gear rings. The input end of the adjusting mechanism is connected to the angle motor 3, and the output end of the adjusting mechanism is connected to the fourth inclined cone 10. The stepless speed-regulating assembly also includes a conical belt 8, one end of which is clamped by the first inclined cone 5 and the second inclined cone 6, and the other end of which is clamped by the third inclined cone 9 and the fourth inclined cone 10. The angle motor 3 is connected to the adjusting mechanism via the adjusting mechanism. The transmission ratio of the continuously variable speed control component is adjusted by adjusting the distance between the third inclined cone 9 and the fourth inclined cone 10. The continuously variable speed control component consists of a first inclined cone 5, a second inclined cone 6, a tension spring, a third inclined cone 9, a fourth inclined cone 10, and a conical belt 8. By adjusting the distance between the third inclined cone 9 and the fourth inclined cone 10, the contact radius of the conical belt 8 is changed, thus achieving continuous adjustment of the transmission ratio. The principle is that the angle motor 3 pushes the fourth inclined cone 10 to move through the adjustment mechanism, changing its distance from the third inclined cone 9. The contact radius of the conical belt 8 on the conical surface of the inclined cone changes accordingly. Combined with the preload of the tension spring, this ensures the conical belt 8 is in contact, thereby achieving continuously variable speed control. This solves the technical problem of discontinuous transmission ratio in traditional stepped speed change systems, achieving a smooth switching of speed from low to high speed, avoiding unsteady flow fields caused by sudden speed changes, and effectively preventing powder sedimentation and droplet dispersion. A positioning frame 13 is fixedly connected to the support plate 34, and the end of the third inclined cone 9 is rotatably connected to the positioning frame 13, thereby achieving stable rotation of the third inclined cone 9.

[0026] Because the sliding positioning stability of the inclined cone in the continuously variable speed control assembly is insufficient, it is prone to displacement due to vibration or uneven force, affecting the clamping force and contact accuracy of the tapered belt 8 and reducing the accuracy of transmission ratio adjustment. Therefore, in one embodiment of the present invention, a drive shaft is fixedly connected to the support frame 12, the third inclined cone 9 is fixedly connected to the drive shaft, and the fourth inclined cone 10 is slidably connected to the drive shaft through the meshing of internal and external gear rings. A second tension spring 20 is provided between the end of the fourth inclined cone 10 and the support frame 12. The drive shaft is provided with a first inner hole, and the first inner hole is provided with several slots 22. The telescopic rod of the adjustment mechanism is slidably connected to the first inner hole. A retaining ring 21 is fixedly connected to the end of the telescopic rod. The diameter of the retaining ring 21 is larger than the diameter of the first inner hole, and the fourth inclined cone 10 is connected to the second tension spring 20. Under the action of the spring, the spring is pressed against the retaining ring 21, and the retaining ring 21 is slidably connected to the slot 22. The third inclined cone 9 and the fourth inclined cone 10 are positioned by the transmission shaft. The second tension spring 20 provides preload to the fourth inclined cone 10. The slot 22 of the first inner hole cooperates with the retaining ring 21 at the end of the telescopic rod to restrict circumferential rotation. The principle is that the transmission shaft provides an axial sliding track for the fourth inclined cone 10, and the second tension spring 20 ensures that the fourth inclined cone 10 always presses against the retaining ring 21. The sliding cooperation between the retaining ring 21 and the slot 22 allows axial displacement and avoids circumferential rotation of the telescopic rod, ensuring the precise movement of the fourth inclined cone 10. This solves the technical problem of unstable inclined cone sliding positioning, improves the adjustment accuracy and operation stability of the stepless speed regulation component, ensures accurate and reliable transmission ratio adjustment, and further ensures stable speed control.

[0027] Because the adjustment mechanism lacks a stable torque transmission and axial displacement conversion structure, the power of the angle motor 3 cannot be accurately transmitted to the stepless speed regulation component, affecting the synchronization of angle and speed linkage adjustment. Therefore, in one embodiment of the present invention, the adjustment mechanism further includes several support rods fixed inside the isolation block 4, an internal threaded column 25 fixed to the end of the support rod, and an external threaded column 24 threadedly connected to the internal threaded column 25. The external threaded column 24 has a square through hole inside, and the end of the external threaded column 24 abuts against the end of the telescopic rod. A square shaft 11 slidably connected to the square through hole is fixed to the output end of the angle motor 3. The internal threaded column 25 is fixed by the support rod, the external threaded column 24 is threadedly connected to the internal threaded column 25, and the square shaft 11 slides with the square through hole of the external threaded column 24 to transmit torque. The principle is that the angle motor 3 drives the square shaft 11 to rotate, and the square shaft 11 drives the external threaded column 24 to rotate through the square through hole. The threaded engagement between column 24 and internal thread column 25 converts rotational motion into axial displacement, thereby pushing the telescopic rod to move, thus realizing the movement of retaining ring 21, and then the movement of fourth inclined cone 10, thereby adjusting the distance between third inclined cone 9 and fourth inclined cone 10. While realizing the distance adjustment, it solves the problem of inaccurate power transmission of the adjustment mechanism, realizes stable torque transmission and precise conversion of motion form, and ensures that the synchronous adjustment of the angle motor 3 to the angle of stirring blade 2 and the transmission ratio of the speed change mechanism is more accurate and the response is faster. The end of the telescopic rod away from retaining ring 21 is provided with a second inner hole 23, and the end of external thread column 24 is provided with a positioning shaft rotatably connected to the second inner hole 23, thereby realizing the stable pushing of telescopic rod by external thread column 24 during the rotation of isolation block 4. In other embodiments, the ends of telescopic rod and external thread column can be connected by thrust ball to ensure the stable adjustment of telescopic rod when the angle of stirring blade 2 is adjusted.

[0028] Since the present invention is used in a large-capacity stirring system, the introduction of the above structure can fully realize the smooth adjustment of the angle and speed of the stirring blade 2. In one embodiment, a first gear 14 is fixedly connected to the output end of the angle motor 3, an internal gear is provided on the first helical gear 17, and a second gear 15 is rotatably connected inside the isolation block 4, which meshes with both the first gear 14 and the internal gear, thereby realizing the adjustment of the tilt angle of the stirring blade 2.

[0029] Because the angle motor 3, gear transmission assembly, and stirring motor 27 inside the isolation block 4 are prone to heat accumulation during emulsification, leading to local temperature rise, this not only accelerates the aging of the motor insulation material and shortens the equipment life, but may also cause the heat-sensitive bioactive ingredients inside the tank 26 to be deactivated due to local overheating, affecting product quality; therefore, in one embodiment of the present invention, a plurality of heat dissipation holes 38 are provided between the isolation block 4 and the fixed cylinder 1, and a plurality of heat dissipation grooves 39 are provided between the drive cavity 31 and the isolation block 4. A cooling fan 32 is provided on the output rod 33 of the stirring motor 27 located inside the fixed cylinder 1. A heat dissipation platform 28 is fixedly connected to the bottom of the tank 26, and the stirring motor 27 is fixedly connected to the heat dissipation platform 28. A heat dissipation cavity 35 is provided inside the heat dissipation platform 28. The heat dissipation cavity 35 is connected to the inside of the fixed cylinder 1 through an air inlet 36. A ring of air outlets 37 is provided on the heat dissipation cavity 35, and the stirring motor 27 is located inside the ring of air outlets 37; the cooling fan 32 is output along with the stirring motor 27. The rod 33 rotates synchronously, generating directional airflow. On one hand, it accelerates airflow between the fixed cylinder 1 and the isolation block 4 through the heat dissipation holes 38 between the isolation block 4 and the fixed cylinder 1, carrying away heat from the surface of the isolation block 4. On the other hand, the airflow enters the heat dissipation chamber 35 through the air inlet 36 of the heat dissipation platform 28, and forms a surrounding airflow through a ring of air outlets 37, directly blowing onto the housing of the stirring motor 27, achieving efficient heat dissipation for the stirring motor 27. At the same time, the heat dissipation groove 39 between the drive chamber 31 and the isolation block 4 increases the heat dissipation surface area of ​​the drive chamber 31, allowing the heat generated by the angle motor 3 and gear transmission to be quickly conducted to the outer wall of the isolation block 4, and then carried away by the airflow. This solves the problem of heat accumulation in multiple components inside the emulsification device, effectively reduces the working temperature inside the isolation block 4 and the stirring motor 27, avoids the deactivation of heat-sensitive bioactive ingredients caused by local overheating, and extends the service life of the stirring motor 27 and the angle motor 3, reducing the risk of equipment failure caused by high temperature.

[0030] In one embodiment, the support plate 34 is provided with an exhaust ring plate 30, and the heat sink 28, the fixing column, the support plate 34, and the exhaust ring plate 30 are provided with an air intake channel 29. One end of the air intake channel 29 is connected to the outside, and the other end is located inside the isolation block 4 and points towards the drive cavity 31. The airflow generated by the cooling fan 32 generates suction, drawing outside air through the heat sink 28, the fixing cylinder 1, the support plate 34, and the exhaust ring plate 30, and finally blowing it directly from the output end of the air intake channel 29 inside the isolation block 4 to the drive cavity 31, precisely purging and cooling the angle motor 3 and the gear transmission assembly; thus forming a circulation of cooling airflow, blowing outside cold air towards the internal parts, and This effectively stabilizes the operating temperature of the angle motor 3 and the stirring motor 27, avoiding problems such as decreased gear meshing accuracy and delayed angle adjustment response caused by high temperature. It further ensures the accuracy of the linkage adjustment between the angle and speed of the stirring blade 2, and improves the operational stability of the entire emulsification device. In addition, the cooling fan 32 is located on the output rod 33 of the stirring motor 27. Its heat dissipation capacity does not change with the speed of the stirring blade 2, nor does it change the speed of the cooling fan 32 as was the case in the past when the speed of the stirring blade 2 needed to be adjusted by changing the speed of the drive motor output, which could have caused changes in the heat dissipation quality. Therefore, the heat dissipation capacity remains online throughout the entire emulsification process.

[0031] Please refer to Figure 7 The present invention also includes an emulsification method for foundation liquid processing, based on the above-described emulsification apparatus for foundation liquid processing, comprising the following steps: Step 1: Add the aqueous phase components, oil phase components, functional powders, bioactive factors, and special additives into tank 26 according to the formula ratio, and close the tank lid; Step 2, Premixing stage: Start the stirring motor 27, drive the rotating shaft 7 to rotate through the synchronous belt transmission assembly 16, start the angle motor 3 to adjust the angle of the stirring blade 2 to 15-20°, and at the same time adjust the speed change mechanism to correspond to a speed of 30-200 rpm through the adjustment mechanism, stir for 5-8 minutes; Step 3, coarse emulsification stage: The angle motor 3 continues to rotate, and the angle of the stirring blade 2 is adjusted to 45-60°. At the same time, the fourth inclined cone 10 is pushed close to the third inclined cone 9 through the adjustment mechanism, and the transmission ratio of the stepless speed regulating component is changed, so that the speed of the isolation block 4 is increased to 800-1200 rpm, and stirring is carried out for 8-12 minutes. Step 4, Fine Emulsification Stage: Angle motor 3 rotates in the opposite direction to adjust the angle of stirring blade 2 back to 30-35°, while the adjustment mechanism resets.
