Description

A dispersion system for producing hair dye Technical Field

[0001] This invention belongs to the field of hair dye production technology, specifically relating to a dispersion system for producing hair dye. Background Technology

[0002] In the production of hair dye, a continuous powder-liquid disperser is a frequently used piece of equipment. A continuous powder-liquid disperser is an online device that continuously introduces powder into a liquid and completes wetting and dispersion. It typically combines multiple processes into one machine, reducing the need for tanks and manual feeding. The common features of mainstream models are: the liquid phase enters the dispersion chamber first; a special rotor-stator structure rotates at high speed, creating a strong turbulence and high shear zone within the chamber; and the structural design draws powder from the powder inlet, hopper, ton bag station, silo, etc., into the liquid flow, completing wetting and dispersion instantly upon entry, thereby reducing the probability of powder agglomeration followed by dispersion.

[0003] Chinese patent CN222641905U discloses a mixing device for raw materials in hair dye production. This device features a semi-automatic feeding mechanism, where manual weighing and batching are followed by mechanical transport. This significantly reduces the labor intensity of manual handling and allows for faster feeding. Furthermore, the material containers are easy to clean and highly adaptable, allowing for quick adjustments or changes to the raw materials to meet different production needs.

[0004] Some hair dyes are sensitive to air and temperature. For example, p-phenylenediamine is easily oxidized. In continuous production, the risk of material exposure is high, which can easily lead to premature oxidation or discoloration. Pure p-phenylenediamine is usually a white to light gray crystal or powder, but it will change color rapidly after being exposed to air, gradually changing from light color to pink, purple, dark brown, and eventually almost black. The purpose of using it in hair dyes is to take advantage of this property so that the color can be fixed on the hair. However, premature oxidation will cause it to lose its hair dyeing function. When these powders are fed into the powder-liquid disperser, the humidity of the environment may also cause the powder to clump, which will not only affect the feeding process, but also affect the dispersion work of the disperser. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dispersion system for producing hair dye.

[0006] The technical solution adopted to solve the above-mentioned technical problems is as follows: a dispersion system for producing hair dye, including a powder-liquid disperser and a feeder, wherein the output end of the feeder is sealed and connected to the inlet of the powder-liquid disperser; the feeder includes a hopper and a feeding cylinder, a sealing cover is sealed on the top of the hopper, a drive motor is installed at the middle position of the top of the sealing cover, a stirring shaft is installed in the drive motor, the stirring shaft passes through the sealing cover, and a feed inlet and an air inlet are opened on the top of the sealing cover; a spiral feeding rod is movably installed in the feeding cylinder, an isolation block is provided at the bottom of the sealing cover, a hollow cavity is opened in the isolation block, and the stirring shaft is located at one end of the hopper. The wall is equipped with a lifting bushing, and several stirring blades are fixedly mounted on the side wall of the lifting bushing. An internal motor is installed in the hollow cavity, and a closing ring is rotatably connected to the top of the hollow cavity. The side wall of the closing ring has a feed hole and an air inlet. The feed hole and the feed port have the same size, and the air inlet and the air outlet have the same size. The output end of the internal motor is equipped with an opening and closing mechanism for driving the closing ring. A fixed disk is also installed in the hollow cavity. Several fixed balls are fixedly mounted on the top of the fixed disk, and several fixed holes are opened at the bottom of the isolation block. Several fixed balls pass through several fixed holes respectively. The side wall of the fixed disk is equipped with a lifting mechanism to drive its lifting and lowering.

[0007] Through the above technical solution, a stirring blade for breaking up powder agglomerates is set inside the feeder of the powder-liquid disperser. And through the setting of the opening and closing mechanism and the lifting mechanism, the broken powder can enter the powder-liquid disperser together with the inert gas, thereby ensuring that the uniform pre-dispersed body inside the powder-liquid disperser is free from agglomeration and has high stability.

[0008] Furthermore, a spline is fixedly provided on the side wall of the stirring shaft, a keyway is provided on the inner wall of the lifting shaft sleeve, the spline is slidably connected to the inner wall of the keyway, an expansion ring is fixedly provided on the top of the lifting shaft sleeve, and several protrusions are fixedly provided on the top of the expansion ring.

[0009] Through the aforementioned technical solution, the precise fit between the spline and keyway enables the lifting bushing to possess unique functions during mechanical operation. Specifically, this design allows the lifting bushing to rotate alongside the stirring shaft while simultaneously moving flexibly upwards or downwards along the axial direction of the shaft. This dual motion capability significantly enhances the functionality and operational flexibility of the equipment. Furthermore, the specially designed expansion ring on the side wall of the lifting bushing, along with the protrusions on it, further optimizes the performance of the entire system. The presence of these components not only improves structural stability but also facilitates the driving of the lifting bushing to complete lifting actions, thereby meeting diverse needs in practical applications.

[0010] Furthermore, a through hole is provided at the middle of the bottom of the isolation block, through which the stirring shaft extends. A feed pipe and an air inlet pipe are also provided at the bottom of the isolation block. The position of the feed pipe corresponds to the position of the feed inlet, and the position of the air inlet pipe corresponds to the position of the air inlet.

[0011] Through the above technical solution, the isolation block adopts a hollow design, with its top designed as a sealed cover and its bottom extending into the internal space of the hopper. The ingenious arrangement of the air inlet pipe and the feed pipe aims to more conveniently introduce powder or inert gas into the hopper. This design can effectively improve the dispersion efficiency of the powder-liquid disperser during operation, making the entire equipment operate more efficiently and stably, thereby meeting the usage requirements under different working conditions and optimizing the overall working performance.

[0012] Furthermore, the opening and closing mechanism includes a driving bevel gear, a rotating bevel gear, and an internal gear ring. The driving bevel gear is fixed to the output end of the internal motor, the rotating bevel gear is fixed to the top of the inner ring of the closed ring, the driving bevel gear meshes with the rotating bevel gear, and the internal gear ring is fixedly disposed on the inner ring sidewall of the closed ring. The distance between the air inlet and the feed inlet is not the same as the distance between the air inlet and the feed inlet.

[0013] Through the above technical solution, the start of the internal motor will cause the drive bevel gear to drive the rotating bevel gear to rotate, which in turn will drive the closed ring to rotate. Since the rotating bevel gear is circular, the rotation of the closed ring driven by the rotating bevel gear will not affect the rotation of the stirring shaft. At the same time, the rotation of the closed ring will drive the internal gear ring to rotate, which facilitates subsequent transmission actions.

[0014] Furthermore, the fixed plate is circular in shape, and self-returning telescopic rods are fixedly installed on the two side walls of the fixed plate. Two placement holes are opened on the side wall of the isolation block, through which the self-returning telescopic rods pass. A grab bar is fixedly installed at the end of the self-returning telescopic rod away from the fixed plate.

[0015] The aforementioned technical solution, by incorporating a telescopic rod with a self-returning function, aims to facilitate the easy return of the fixed disc to its initial position after it has been lifted. This allows the protrusions on the fixed disc to re-engage with the fixed ball and be lifted again, creating a repetitive cycle. The core significance of this design lies in achieving high-frequency, small-amplitude vibration between the lifting shaft sleeve and the stirring blades through this repetitive motion. This vibration is crucial for powder processing, as it enables more efficient and uniform dispersion of the powder, thereby improving overall work efficiency and dispersion quality.

[0016] Furthermore, the distance between the two self-returning telescopic rods is greater than the diameter of the expansion ring, the top sidewall of the expansion ring is arc-shaped, and the end of the grab rod facing the expansion ring is also arc-shaped.

[0017] Through the above technical solution, the grab bar fixedly installed at the end of the self-returning telescopic rod will naturally return to its initial position under the action of the self-returning telescopic rod's own rebound force. To ensure that the grab bar can more easily grasp the side wall of the expansion ring and smoothly lift the expansion ring after grasping it, special design and optimization of the grab bar's structure are required. One key design point is to provide the grab bar with an arc-shaped end that facilitates obstacle avoidance. This arc-shaped end design can effectively reduce the obstacles that the grab bar may encounter during operation, allowing it to more smoothly avoid obstacles when approaching the side wall of the expansion ring, thereby improving the success rate and efficiency of the grab bar grasping the expansion ring and lifting the entire structure.

[0018] Furthermore, the lifting mechanism includes an internal gear, a lifting screw, a lifting sleeve, a fixed rod, a lifting ring, and two connecting rods. The internal gear is rotatably connected to the side wall of the sealing cover and meshes with the internal gear ring. The lifting screw is fixedly connected to the side wall of the internal gear. The fixed rod is fixedly installed on the side wall of the sealing cover. The lifting sleeve is threadedly connected to the side wall of the lifting screw. The lifting ring is movably sleeved on the outside of the fixed rod. The two connecting rods are respectively fixedly installed at the bottom of the fixed plate. One of the connecting rods is fixedly connected to the side wall of the lifting sleeve, and the other connecting rod is fixedly connected to the side wall of the lifting ring.

[0019] Through the above technical solution, the rotation of the closed ring will drive the internal gear ring to rotate. Due to the meshing effect, the internal gear will also rotate, which in turn will drive the lifting screw to rotate. The lifting sleeve meshing with it will move up and down along the lifting screw. Under the drive of the connecting rod, the fixed plate will move up and down with the fixed ball, so that the fixed ball will extend out of the fixed hole.

[0020] Furthermore, both the lifting screw and the fixed rod are fixedly provided with a baffle plate at their tops. The outer diameter of the baffle plate is larger than the outer diameter of the lifting screw and also larger than the outer diameter of the fixed rod.

[0021] With the above technical solution, since the lifting screw sleeve and the lifting ring need to move up or down along the lifting screw and the fixed rod respectively during operation, in order to effectively prevent the lifting screw sleeve and the lifting ring from completely separating during movement, it is necessary to set up a baffle plate. The baffle plate can prevent the lifting screw sleeve and the lifting ring from separating by blocking the movement.

[0022] Furthermore, the sidewall of the grab bar abuts against the sidewall of the isolation block, and the grab bar is located outside several fixed balls.

[0023] With the above technical solution, given the self-returning telescopic rod's characteristic of pulling back the gripping rod, the gripping rod will continuously maintain a tight abutment against the side wall of the isolation block under its influence. In this situation, to ensure the gripping rod can smoothly and effectively grasp the side wall of the fixed disk, the dimensional fit between the various components must be fully considered during design and adjustment. Specifically, this requires carefully setting the distance between the two gripping rods to be slightly larger than the diameter of the fixed disk itself. This ensures that under the pull-back force of the self-returning telescopic rod, the gripping rod can maintain its abutment against the side wall of the isolation block without the distance being too small, thus preventing effective gripping of the fixed disk's side wall.

[0024] Furthermore, the feed pipe and the air inlet pipe have the same length, the feed pipe does not contact the side wall of the sealing ring, and a silicone guide ring is provided on the side wall of the feed pipe facing the feed hole.

[0025] With the above technical solution, since the closed ring needs to rotate under the drive of the opening and closing mechanism, in order to prevent unnecessary friction between the feed pipe and the air inlet pipe and the closed ring, the feed pipe and the air inlet pipe need to be set to be slightly shorter. However, a silicone guide ring that facilitates flow guidance also needs to be set between the feed pipe and the feed port.

[0026] The beneficial effects of this invention are as follows: This invention, by setting stirring blades inside the feeder of the powder-liquid disperser to break up powder agglomerates, and through the setting of the opening and closing mechanism and the lifting mechanism, allows the broken powder to enter the powder-liquid disperser along with inert gas. The inert gas can isolate air, thus preventing air from being mixed into the powder-liquid disperser during subsequent operation, thereby ensuring that the uniform pre-dispersed material inside the powder-liquid disperser is free of agglomeration and has high stability. This invention, by setting a fixed ball, a protrusion, and a self-returning telescopic rod, allows the stirring blades to rise and fall along the stirring shaft by lifting the protrusion when the stirring shaft is driven by the motor. The self-returning telescopic rod facilitates the return of the lifted fixed plate to its original position, allowing the protrusion on the fixed plate to be lifted again by the fixed ball, thereby achieving high-frequency, small-amplitude vibration of the lifting shaft sleeve and the stirring blades, resulting in better dispersion of the powder. The melanin dispersed by this invention... This hair dye, while meeting the relevant technical indicators and safety requirements for hair dyes as special-purpose cosmetics, further demonstrates good formulation compatibility, system mildness, and efficacy scalability. The manufacturing method is not limited to hair dye systems but can be directly compatible and adaptable to various common cosmetic carriers and dosage forms, achieving stable introduction and functional expression of melanin-related active ingredients. This manufacturing method can be used in, but is not limited to, the following hair care and styling products: shampoo coloring products, conditioners, hair conditioning agents, hair care products, hair masks, leave-in conditioners, scalp serums, hair oils, styling gels, scalp care gels, hair waxes, and 2-in-1 shampoos and conditioners. This invention enables the cross-scenario reuse of active ingredients between the special cosmetics and general cosmetics fields, significantly expanding the applicability and productization path of the same technical solution, and providing the cosmetics industry with a novel formulation technology solution with richer functional dimensions and extensible application scenarios.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] As shown in Figure 1, this embodiment provides a dispersion system for producing hair dye, including a powder-liquid disperser 1 and a feeder, wherein the output end of the feeder is sealed and connected to the inlet of the powder-liquid disperser 1.

[0031] As shown in Figure 2, the feeder includes a hopper 2 and a feeding cylinder 3. A sealing cover 4 is installed on the top of the hopper 2. A drive motor 5 is installed in the middle of the top of the sealing cover 4. A stirring shaft 6 is installed in the drive motor 5. The stirring shaft 6 passes through the sealing cover 4. A feed inlet 7 and an air inlet 8 are opened on the top of the sealing cover 4. A thrust bearing can also be installed in the sealing cover 4 to withstand axial pressure.

[0032] As shown in Figures 3-6, a spiral feeding rod 9 is movably installed in the feeding cylinder 3, an isolation block 10 is installed at the bottom of the sealing cover 4, and a hollow cavity is opened in the isolation block 10. A lifting shaft sleeve 11 is movably installed on one side wall of the stirring shaft 6 located in the hopper 2. Several stirring blades 12 are fixedly installed on the side wall of the lifting shaft sleeve 11, a spline 20 is fixedly installed on the side wall of the stirring shaft 6, and a keyway 21 is opened on the inner wall of the lifting shaft sleeve 11. The spline 20 is slidably connected to the inner wall of the keyway 21. An expansion ring 22 is fixedly installed on the top of the lifting shaft sleeve 11, and several protrusions 23 are fixedly installed on the top of the expansion ring 22. The cooperation between the spline 20 and the keyway 21 allows the lifting shaft sleeve 11 to move up and down along the axial direction of the stirring shaft 6 while rotating with it. The expansion ring 22 on the side wall of the lifting shaft sleeve 11 and the protrusions 23 thereon can easily drive the lifting shaft sleeve 11 to move up and down.

[0033] Referring to Figure 10, it can be seen that a through hole 24 is provided at the middle of the bottom of the isolation block 10, and the stirring shaft 6 extends out of the through hole 24. The bottom of the isolation block 10 is also provided with a feed pipe 25 and an air inlet pipe 26. The position of the feed pipe 25 corresponds to the position of the feed inlet 7, and the position of the air inlet pipe 26 corresponds to the position of the air inlet 8. The isolation block 10 is a hollow design. The top of the isolation block 10 is a sealing cover 4, and the bottom is located inside the hopper 2. The air inlet pipe 26 and the feed pipe 25 are provided to facilitate the pouring of powder or inert gas into the hopper 2, thereby improving the dispersion efficiency of the powder-liquid disperser 1.

[0034] The feed pipe 25 and the air inlet pipe 26 have the same length. The feed pipe 25 does not contact the side wall of the sealing ring 14. A silicone guide ring is provided on the side wall of the feed pipe 25 facing the feed hole 15. Since the sealing ring 14 needs to rotate under the drive of the opening and closing mechanism, in order to prevent unnecessary friction between the feed pipe 25, the air inlet pipe 26 and the sealing ring 14, the feed pipe 25 and the air inlet pipe 26 need to be set to be slightly shorter. However, a silicone guide ring that facilitates flow guidance needs to be provided between the feed pipe 25 and the feed port 7 to prevent the introduced powder from falling into the hollow cavity. At the same time, the elastic silicone guide ring can also deform to a certain extent, thereby facilitating the movement of the feed pipe 25.

[0035] As shown in Figures 7 and 9, an internal motor 13 is installed in the hollow cavity. A closed ring 14 is rotatably connected to the top of the hollow cavity. The side wall of the closed ring 14 has a feed hole 15 and an air inlet 16. The feed hole 15 and the feed inlet 7 have the same size, and the air inlet 16 and the air inlet 8 have the same size. The output end of the internal motor 13 is equipped with an opening and closing mechanism for driving the closed ring 14. The opening and closing mechanism includes a driving bevel gear 27, a rotating bevel gear 28, and an internal gear ring 29. The driving bevel gear 27 is fixed to the output end of the internal motor 13, and the rotating bevel gear 28 is fixed to the top of the inner ring of the closed ring 14. The driving bevel gear 27 meshes with the rotating bevel gear 28. The gear ring 29 is fixedly installed on the inner ring side wall of the closed ring 14. The distance between the air inlet 16 and the feed inlet 15 is not the same as the distance between the air inlet 8 and the feed inlet 7. Therefore, when the air inlet 16 is connected to the air inlet 8, the feed inlet 7 is not connected to the feed inlet 15. The start of the internal motor 13 will cause the drive bevel gear 27 to drive the rotating bevel gear 28 to rotate, which in turn causes the rotating bevel gear 28 to drive the closed ring 14 to rotate. Since the rotating bevel gear 28 is circular, the rotation of the closed ring 14 driven by the rotating bevel gear 28 will not affect the rotation of the stirring shaft 6. At the same time, the rotation of the closed ring 14 will drive the internal gear ring 29 to rotate, which facilitates the subsequent transmission action.

[0036] Referring to Figures 7 and 10, a fixed plate 17 is also provided in the hollow cavity. Several fixed balls 18 are fixedly installed on the top of the fixed plate 17. Several fixed holes 19 are opened at the bottom of the isolation block 10. Several fixed balls 18 pass through several fixed holes 19 respectively. The fixed balls 18 mentioned here are actually cylindrical with an arc-shaped top. The position of the fixed balls 18 corresponds one-to-one with the position of the fixed holes 19.

[0037] Referring to Figure 8, the fixed disk 17 is circular in shape. Self-returning telescopic rods 30 are fixedly installed on both sides of the fixed disk 17. Two placement holes 31 are opened on the side wall of the isolation block 10. The self-returning telescopic rods 30 pass through the placement holes 31. A gripping rod 32 is fixedly installed at the end of the self-returning telescopic rods 30 away from the fixed disk 17. The self-returning telescopic rods 30 are set to facilitate the fixed disk 17 that has been lifted back to its original position, so that the protrusion 23 on the fixed disk 17 can be lifted again by the fixed ball 18. This achieves high-frequency small-amplitude vibration of the lifting shaft sleeve 11 and the stirring blade 12, which better disperses the powder.

[0038] The side wall of the grab bar 32 abuts against the side wall of the isolation block 10. The grab bar 32 is located outside several fixed balls 18. Due to the pull-back effect of the self-returning telescopic rod 30 on the grab bar 32, the grab bar 32 will maintain the abutting effect against the side wall of the isolation block 10. In order to facilitate the grab bar 32 to grab the side wall of the fixed plate 17, the distance between the two grab bars 32 needs to be set slightly larger than the diameter of the fixed plate 17.

[0039] The distance between the self-returning telescopic rods 30 is greater than the diameter of the expansion ring 22. The top sidewall of the expansion ring 22 is arc-shaped, and the end of the grab rod 32 facing the expansion ring 22 is also arc-shaped. The grab rod 32 fixed to the end of the self-returning telescopic rod 30 will tend to return to the initial position under the action of the self-returning telescopic rod 30. In order to facilitate the grab rod 32 to grab the sidewall of the expansion ring 22 and lift the expansion ring 22, an arc-shaped end that is easy to avoid is required.

[0040] The side wall of the fixed plate 17 is provided with a lifting mechanism to drive its lifting and lowering. The lifting mechanism includes an internal gear 33, a lifting screw 34, a lifting sleeve 35, a fixed rod 36, a lifting ring 37, and two connecting rods 38. The internal gear 33 is rotatably connected to the side wall of the sealing cover 4 and meshes with the internal gear ring 29. The lifting screw 34 is fixedly connected to the side wall of the internal gear 33. The fixed rod 36 is fixedly installed on the side wall of the sealing cover 4. The lifting sleeve 35 is threadedly connected to the side wall of the lifting screw 34. The lifting ring 37 is movably sleeved on the outside of the fixed rod 36. The two connecting rods 38 are respectively... Fixedly installed at the bottom of the fixed plate 17, one connecting rod 38 is fixedly connected to the side wall of the lifting screw sleeve 35, and the other connecting rod 38 is fixedly connected to the side wall of the lifting ring 37. The rotation of the closed ring 14 will drive the internal gear ring 29 to rotate. Due to the meshing action, the internal gear 33 will also rotate, thereby driving the lifting screw 34 to rotate. The lifting screw sleeve 35, which meshes with it, will move up and down along the lifting screw 34. Driven by the connecting rod 38, the fixed plate 17 will move up and down together with the fixed ball 18, thereby causing the fixed ball 18 to extend out of the fixed hole 19.

[0041] During the rotation of the stirring shaft 6, a very small up-and-down reciprocating motion is simultaneously superimposed, with a displacement range of approximately ±0.1 to 0.5 mm. This motion creates an effect similar to hammer shearing. This special motion pattern is generally more advantageous than radial oscillation of the same amplitude in breaking up agglomerates, mainly due to its more significant effect and relatively higher safety during operation. Because the high-frequency, small-amplitude motion can further generate "micro-shear peaks" in the impeller area, it is usually very effective against soft agglomerates, flocs, and secondary agglomerates, thus better achieving the purpose of breaking up agglomerates.

[0042] Both the lifting screw 34 and the fixed rod 36 are fixedly provided with a baffle plate 39. The outer diameter of the baffle plate 39 is larger than the outer diameter of the lifting screw 34 and also larger than the outer diameter of the fixed rod 36. Since the lifting sleeve 35 and the lifting ring 37 need to move up and down along the lifting screw 34 and the fixed rod 36 respectively, in order to prevent the lifting sleeve 35 and the lifting ring 37 from completely separating, the baffle plate 39 is required to prevent the two from separating.

[0043] The working principle of this embodiment is as follows: In the initial state, the feed hole 15 is aligned with the feed inlet 7, while the air inlet 16 is not aligned with the air inlet 8. Therefore, the operator can feed powder into the feed inlet 7. After feeding, the internal motor 13 is started. The rotation of the internal motor 13 will cause the drive bevel gear 27 to drive the rotating bevel gear 28 to rotate, which in turn causes the rotating bevel gear 28 to drive the closed ring 14 to rotate, thus causing the feed hole 15 and feed inlet 7 to be misaligned. Then, the air inlet 16 is connected to the air inlet 8, and the operator can then introduce inert gas into the hopper 2. While the internal motor 13 drives the closed ring 14 to rotate, the internal gear ring 29 inside the closed ring 14 will drive the internal gear 33 to rotate, which in turn drives the lifting screw 34 to rotate. The lifting sleeve 35, which meshes with it, will move up and down along the lifting screw 34. Driven by the connecting rod 38, the fixed plate 17 will move up and down along with the fixed ball 18, thus causing the fixed ball 18 to extend out of the fixed hole 19. After the inert gas has been introduced for a period of time, The internal motor 13 is driven to rotate again, which cuts off the connection between the air inlet 16 and the air inlet 8. At this time, both the feed inlet 7 and the air inlet 8 are closed, and the fixed ball 18 extends completely out of the fixed hole 19. Since the fixed ball 18 is fully extended, the fixed plate 17 will also be in the position closest to the expansion ring 22. At this time, the self-returning telescopic rod 30 will also descend together with the fixed plate 17, so that the arc-shaped end gripping rod 32 passes over the side wall of the expansion ring 22 and grabs the back of the expansion ring 22. Then the drive... When the motor 5 starts, it drives the stirring shaft 6 to rotate. Since the fixed ball 18 has been extended, under the action of the self-returning telescopic rod 30, the fixed ball 18 will be in a state of abutting against the top of the expansion ring 22. The rotation of the expansion ring 22 will cause the protrusion 23 to rotate synchronously, thereby causing the protrusion 23 to contact the fixed ball 18. This causes the lifting shaft sleeve 11 and the stirring blade 12 to rotate and lift at the same time, thereby performing hammer-type shearing on the powder. Then, the powder will be introduced into the powder-liquid disperser 1 for the production of hair dye.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
