Abstract
Description
Technical Field
[0001] This invention belongs to the field of stirring device technology, and more specifically, relates to a stirring device for cosmetic raw materials used in cosmetic production. Background Technology
[0002] In the cosmetic production process, mixing is a crucial step. However, traditional cosmetic mixing equipment has many problems.
[0003] Traditionally, the angle of the mixing blades is fixed and cannot be automatically changed according to the rotation direction of the drive shaft. As a result, when the drive shaft rotates forward or backward, it cannot properly adjust the shear angle to match the rotation direction, which affects the mixing effect and efficiency.
[0004] Moreover, since the blade angle is not adjustable, it is difficult to generate an ideal flow field and shear force, making it impossible to effectively mix and disperse raw materials. This results in long mixing time and high energy consumption. During the mixing process, cosmetic raw materials are prone to sticking to the inner wall of the mixing tank, which not only wastes raw materials and affects the stability of product quality and performance, but also increases the cost and time of manual cleaning of the inner wall and reduces production efficiency.
[0005] Meanwhile, existing mixing devices are not good at dealing with the problems of mixing dead zones and uneven material flow, and cannot fully mix the raw materials in all locations, resulting in insufficient overall uniformity.
[0006] In summary, traditional cosmetic mixing equipment has shortcomings in terms of blade angle adjustment, internal wall adhesion treatment, mixing uniformity, and efficiency, and needs to be improved to meet the production requirements of high quality and high efficiency. Summary of the Invention
[0007] To address the aforementioned technical problems, this invention provides a cosmetic raw material mixing device for cosmetic production.
[0008] A cosmetic raw material mixing device for cosmetic production includes a mixing tank. An electric motor is fixedly mounted on the top of the mixing tank, facing downwards. A drive shaft is fixedly mounted on the end of the motor's output shaft. An inner groove is formed inside the drive shaft, and a central frame is positioned at the center of the inner groove. A spur bevel gear is fixedly fitted onto the surface of the central frame near its top. At least two bevel gears mesh with the lower part of the spur bevel gear. A second gear is positioned on the back of each bevel gear. Multiple fixed sleeves are fixedly fitted onto the surface of the drive shaft. At least two main blades are positioned on the outer ring of each fixed sleeve. A first rotating shaft is fixedly mounted on the back of each main blade, passing through the fixed sleeve and the drive shaft. The first gear is located within the inner groove. A first gear is fixedly mounted at the end of each first rotating shaft. A sliding rod meshes with the side of each first gear. A second gear meshes with the upper section of the sliding rod.
[0009] Preferably, a second rotating shaft is fixedly installed on the back of each bevel gear, each second gear is fixedly sleeved on the outside of the second rotating shaft, the rear end of each second rotating shaft is rotatably connected to the inner wall of the transmission shaft, each sliding rod has a section of teeth near the second gear and the first gear, and each sliding rod is slidably installed inside the transmission shaft.
[0010] Preferably, each sliding rod has an L-shaped sliding rod fixedly installed on its side wall, and the inside of the drive shaft has a groove that matches the L-shaped sliding rod. Each L-shaped sliding rod is located in the groove of the drive shaft. The lower end of the drive shaft is rotatably connected to the bottom of the mixing tank, and the lower end of the central frame is fixedly connected to the bottom of the mixing tank. An upper fixing plate is fixedly sleeved on the outer ring of the drive shaft near the top. A connecting frame is fixedly installed on the lower side of the upper fixing plate near the outer side wall. A cylindrical groove is opened on the side wall of the connecting frame, and a pressure switch is fixedly installed on the top of the cylindrical groove.
[0011] Preferably, the inner wall of the mixing tank is provided with a threaded groove, and an annular frame is installed inside the mixing tank. The outer wall of the annular frame is threaded to engage with the inner wall of the mixing tank. A connecting box is fixedly installed on the inner wall of the annular frame. A circular groove is provided on the side wall of the connecting box. Two clips are fixedly installed on the side wall of the connecting box located on the upper and lower sides of the circular groove. A connecting ball is rotatably installed inside the circular groove, and the connecting ball can rotate between the two clips. The characteristic is that the two clips and the connecting ball on the side wall of the connecting box are all located in the cylindrical groove provided by the connecting frame.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] In this invention, multiple bevel gears revolve below a spur bevel gear. Because the spur bevel gear and the bevel gear mesh, the revolve of the bevel gear causes it to rotate. This rotation of the bevel gear then causes the second gear to rotate. The rotation of the second gear meshes with the teeth on the sidewall of the sliding rod, simultaneously causing the sliding rod to move upwards or downwards. This upward or downward movement of the sliding rod causes the first gear below to rotate. The rotation of the first gear changes the angle of the main impeller. By designing the main impeller to automatically change its angle according to the rotation direction of the drive shaft, the shearing angle can be changed in accordance with the rotation direction of the drive shaft. This allows for effective stirring of the cosmetic raw materials in the mixing tank when the drive shaft rotates in both directions.
[0014] In this invention, the counterclockwise rotation of the second gear drives the sliding rod to move upward. The L-shaped sliding rod on the side wall of the sliding rod slides upward inside the transmission shaft. The upward movement of the sliding rod drives the main blade to rotate counterclockwise by a certain angle through the first gear and the first rotating shaft. Similarly, when the transmission shaft rotates counterclockwise, the main blade will rotate clockwise by a certain angle. At this time, the main blade can adaptively adjust its angle according to the rotation of the transmission shaft, thereby automatically adjusting the shear angle. Different blade angles can generate different flow fields and shear forces, thereby more effectively mixing and dispersing raw materials, shortening the mixing time, and effectively improving the mixing efficiency. A suitable blade angle can achieve the required mixing effect in a more energy-efficient way, reducing unnecessary energy consumption.
[0015] In this invention, the second gear engages with the sliding rod through its teeth. After the last tooth on the sliding rod surface is engaged, the sliding rod may fall downwards or move upwards due to resistance from the main blade. The distance the sliding rod moves each time is equal to the distance between two teeth on the second gear. Thus, when the transmission shaft is operating normally, the sliding rod continuously drives the main blade to rotate at small angles, causing the main blade to fan up and down during stirring. By utilizing the characteristics of the tooth spacing of the sliding rod to adjust the angle of the main blade, the flow path and velocity distribution of the material in the stirring container can be changed, reducing dead zones in the stirring process and ensuring that the raw materials are fully stirred in all positions, thereby improving the overall uniformity.
[0016] In this invention, the outer wall of the annular frame is threaded into the inner wall of the mixing tank. Therefore, the annular frame moves upwards during rotation, scraping the inner wall of the mixing tank and removing cosmetic raw materials adhering to it. Simultaneously, the rotation of the annular frame drives multiple auxiliary blades on the inner wall to rotate, providing secondary mixing of the cosmetics within the mixing tank. By designing a movable annular frame within the mixing tank, the amount of cosmetic raw materials adhering to the inner wall is reduced, effectively improving mixing efficiency. This prevents raw materials adhering to the inner wall from being unable to participate in mixing and subsequent processing, thereby increasing raw material utilization, reducing production costs, and preventing the adhering raw materials from deteriorating due to prolonged contact with the inner wall or mixing with subsequent batches, thus affecting the quality and performance stability of the entire batch of cosmetics. Furthermore, manual cleaning of the inner wall is unnecessary, saving time and manpower, increasing the effective operating time of the equipment, and ultimately improving production efficiency.
[0017] In this invention, the connecting frame applies force to the connecting ball, and the force on the connecting ball is transmitted to the ring frame. When the ring frame moves upward, it drives the connecting ball to move upward in the cylindrical groove opened in the connecting frame. At the same time, the connecting ball can rotate freely in the cylindrical groove. When the connecting box moves upward and contacts the pressure switch, the pressure switch sends a signal to the drive shaft to reverse. At this time, the ring frame can move downward again. By engaging the connecting ball into the connecting frame, the connecting frame drives the ring frame to rotate while ensuring that the ring frame can move normally upward or downward.

[0028] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0029] Please see Figures 1-9 This invention provides a cosmetic raw material mixing device for cosmetic production, including a mixing tank 1. A motor 11 is fixedly mounted on the top of the mixing tank 1, with the motor 11 facing downwards. A transmission shaft 22 is fixedly mounted on the end of the output shaft of the motor 11. An inner groove 35 is formed inside the transmission shaft 22, and a central frame 3 is provided at the center of the inner groove 35. A straight bevel gear 31 is fixedly fitted on the surface of the central frame 3 near the top. At least two bevel gears 34 mesh below the straight bevel gear 31. Multiple bevel gears 34 revolve below the straight bevel gear 31. Because the straight bevel gear 31 and the bevel gears 34 mesh, the revolve of the bevel gears 34 will drive their own rotation. The rotation of the bevel gears 34 will cause the second gear 33 to rotate. The rotation of the second gear 33 will interact with the sliding rod 27. The teeth on the sidewall mesh, simultaneously driving the sliding rod 27 to move up or down. The upward or downward movement of the sliding rod 27 will drive the first gear 26 below to rotate. The rotation of the first gear 26 will change the angle of the main blade 24. A second gear 33 is provided on the back of each bevel gear 34. Multiple fixed sleeves 23 are fixedly sleeved on the surface of the drive shaft 22. At least two main blades 24 are provided on the outer ring of each fixed sleeve 23. A first rotating shaft 25 is fixedly installed on the back of each main blade 24. The first rotating shaft 25 passes through the fixed sleeve 23 and the drive shaft 22. The first gear 26 is located in the inner groove 35. A first gear 26 is fixedly installed at the end of each first rotating shaft 25. A sliding rod 27 is meshed on the side of each first gear 26. The second gear 33 meshes with the upper section of the sliding rod 27.
[0030] Each bevel gear 34 has a second rotating shaft 32 fixedly mounted on its back. Each second gear 33 is fixedly sleeved on the outside of the second rotating shaft 32. The rear end of each second rotating shaft 32 is rotatably connected to the inner wall of the transmission shaft 22. The counterclockwise rotation of the second rotating shaft 32 will drive the second gear 33 to rotate counterclockwise. The counterclockwise rotation of the second gear 33 will drive the sliding rod 27 to move upward. The L-shaped sliding rod 28 on the side wall of the sliding rod 27 slides upward inside the transmission shaft 22. The upward movement of the sliding rod 27 will drive the main blade 24 to rotate counterclockwise by a certain angle through the first gear 26 and the first rotating shaft 25. Each sliding rod 27 has a section of teeth near the second gear 33 and the first gear 26. Each sliding rod 27 is slidably mounted inside the transmission shaft 22.
[0031] Each sliding rod 27 has an L-shaped sliding rod 28 fixedly installed on its side wall. The drive shaft 22 has a groove inside that matches the L-shaped sliding rod 28. Each L-shaped sliding rod 28 is located within the groove on the drive shaft 22. After the last tooth on the surface of the sliding rod 27 engages with the sliding rod 27, the sliding rod 27 may fall downwards or move upwards due to resistance from the main blade 24. The distance the sliding rod 27 moves each time is equal to the distance between two teeth on the second gear 33. When the drive shaft 22 is operating normally, the sliding rod 27 will continuously drive the main blade 24 to rotate at a small angle. The lower end of the drive shaft 22 is rotatably connected to the bottom of the mixing tank 1, and the lower end of the center frame 3 is fixedly connected to the bottom of the mixing tank 1. The upper fixed plate 12 is fixedly sleeved on the outer ring of the drive shaft 22 near the top. The connecting frame 13 is fixedly installed on the lower side of the upper fixed plate 12 near the outer side wall. The side wall of the connecting frame 13 is provided with a cylindrical groove 14, and a pressure switch 15 is fixedly installed on the top of the cylindrical groove 14.
[0032] The inner wall of the mixing tank 1 is provided with a threaded groove. An annular frame 16 is installed inside the mixing tank 1. The outer wall of the annular frame 16 is threaded to engage with the inner wall of the mixing tank 1. A connecting box 17 is fixedly installed on the inner wall of the annular frame 16. A circular groove 18 is provided on the side wall of the connecting box 17. Two clips 19 are fixedly installed on the side wall of the connecting box 17 located on the upper and lower sides of the circular groove 18. A connecting ball 2 is rotatably installed inside the circular groove 18. The outer wall of the annular frame 16 is threaded to engage with the inner wall of the mixing tank 1. Therefore, the annular frame 16 will move upward when rotating. When the annular frame 16 moves upward, it will scrape the inner wall of the mixing tank 1, scraping off the cosmetic raw materials adhering to the inner wall of the mixing tank 1. At the same time, the rotation of the annular frame 16 will drive the rotation of multiple auxiliary blades 21 on the inner wall, and the connecting ball 2 can rotate between the two clips 19. The characteristic is that the two clips 19 and the connecting ball 2 on the side wall of the connecting box 17 are all located in the cylindrical groove 14 opened in the connecting frame 13.
[0033] Working principle:
[0034] First, after placing the cosmetic raw materials into the mixing tank 1, the motor 11 is started. The motor 11 drives the transmission shaft 22 to rotate via the output shaft. The rotation of the transmission shaft 22 drives multiple fixed sleeves 23 to rotate, which in turn drives multiple main impellers 24 to rotate. Simultaneously, the rotation of the transmission shaft 22 also drives multiple sliding rods 27, bevel gears 34, and second gears 33 to rotate in a circular motion. The multiple bevel gears 34 revolve below the straight bevel gears 31. Since the straight bevel gears 31 and the bevel gears 34 are meshed, the revolution of the bevel gears 34 will cause them to rotate on their own axis. The rotation of the second gear 33 by the self-rotation mechanism causes the second gear 33 to rotate. The rotation of the second gear 33 will mesh with the teeth on the side wall of the sliding rod 27, and at the same time drive the sliding rod 27 to move up or down. The upward or downward movement of the sliding rod 27 will drive the first gear 26 below to rotate. The rotation of the first gear 26 will change the angle of the main blade 24. By designing the main blade 24 to automatically change its angle according to the rotation direction of the drive shaft 22, the shearing angle can be changed in accordance with the rotation direction of the drive shaft 22. Thus, the cosmetic raw materials in the mixing tank 1 can be effectively stirred when the drive shaft 22 rotates in both directions.
[0035] In the second step, when the drive shaft 22 rotates clockwise, the bevel gear 34 revolves clockwise around the spur bevel gear 31, and simultaneously rotates counterclockwise. This counterclockwise rotation of the bevel gear 34 drives the second rotating shaft 32 to rotate counterclockwise, which in turn drives the second gear 33 to rotate counterclockwise. This counterclockwise rotation of the second gear 33 causes the sliding rod 27 to move upwards. The L-shaped sliding rod 28 on the side wall of the sliding rod 27 slides upwards inside the drive shaft 22. This upward movement of the sliding rod 27 is transmitted through the first gear 26 and the second gear 27... A rotating shaft 25 drives the main blade 24 to rotate counterclockwise by a certain angle. Similarly, when the drive shaft 22 rotates counterclockwise, the main blade 24 will rotate clockwise by a certain angle. At this time, the main blade 24 can adaptively adjust the angle according to the rotation of the drive shaft 22, thereby automatically adjusting the shear angle. Different blade angles can generate different flow fields and shear forces, thereby mixing and dispersing raw materials more effectively, shortening the mixing time, and effectively improving the mixing efficiency. A suitable blade angle can achieve the required mixing effect in a more energy-efficient way and reduce unnecessary energy consumption.
[0036] Because the teeth on the surface of the sliding rod 27 are not fully toothed, but only a short distance away from the second gear 33 and the first gear 26, the second gear 33 engages with the sliding rod 27 through its teeth. After the second gear 33 engages with the last tooth on the surface of the sliding rod 27, the sliding rod 27 may fall downwards or move upwards due to the resistance of the main blade 24. The distance the sliding rod 27 moves each time is equal to the distance between two teeth on the second gear 33. Thus, when the transmission shaft 22 is operating normally, the sliding rod 27 will continuously drive the main blade 24 to rotate at a small angle, causing the main blade 24 to fan up and down during stirring. By utilizing the characteristics of the tooth spacing of the sliding rod 27 to adjust the angle of the main blade 24, the flow path and speed distribution of the material in the mixing container can be changed, reducing the stirring dead zone and ensuring that the raw materials are fully stirred in all positions, thereby improving the overall uniformity.
[0037] Thirdly, the rotation of the drive shaft 22 will drive the upper fixed plate 12 to rotate, which in turn will drive the connecting frame 13 to rotate in a circular motion. The rotation of the connecting frame 13 will drive the annular frame 16 to rotate via the connecting ball 2. The outer wall of the annular frame 16 is threadedly engaged with the inner wall of the mixing tank 1. Therefore, the annular frame 16 will move upward when rotating. When the annular frame 16 moves upward, it will scrape the inner wall of the mixing tank 1, scraping off the cosmetic raw materials adhering to the inner wall of the mixing tank 1. At the same time, the rotation of the annular frame 16 will drive the multiple auxiliary blades 21 on the inner wall to rotate, and the rotation of the auxiliary blades 21 will cause the mixing tank to rotate. The cosmetics in mixing tank 1 are subjected to secondary stirring. By designing a movable ring frame 16 inside the mixing tank 1, the amount of cosmetic raw materials adhering to the inner wall of the mixing tank 1 can be reduced, which can effectively improve the stirring efficiency and prevent the raw materials adhering to the inner wall from being unable to participate in stirring and subsequent processing. This improves the utilization rate of raw materials, reduces production costs, and prevents the adhering raw materials from adhering to the inner wall for a long time and deteriorating or mixing with subsequent batches, which would affect the quality and performance stability of the entire batch of cosmetics. There is no need for manual shutdown to clean the inner wall, which saves time and manpower, increases the effective operating time of the equipment, and thus improves production efficiency.
[0038] When the connecting frame 13 rotates, it applies force to the connecting ball 2, which in turn transmits the force to the ring frame 16. As the ring frame 16 moves upward, it drives the connecting ball 2 to move upward within the cylindrical groove 14 of the connecting frame 13. Simultaneously, the connecting ball 2 can rotate freely within the cylindrical groove 14. When the connecting box 17 moves upward and contacts the pressure switch 15, the pressure switch 15 sends a signal to the drive shaft 22 to reverse. At this time, the ring frame 16 can move downward again. By engaging the connecting ball 2 within the connecting frame 13, the connecting frame 13 drives the ring frame 16 to rotate while ensuring that the ring frame 16 can move normally upward or downward.
