Description

Technical Field

[0001] The present invention and the technical field of surfactants particularly relate to a cosmetic powder-in-water mixing device. Background Art

[0002] Loose powder is a type of cosmetic, also known as "setting powder" or "honey powder"; it generally contains fine talcum powder, which can absorb excess facial oil and reduce facial shine. It can comprehensively adjust the skin tone, make makeup more lasting, smooth and delicate, and prevent makeup from coming off.

[0003] In the production process of loose powder, powder-water mixing is a crucial process, and its quality directly affects the quality of the final product. Although traditional powder mixers can meet production needs to a certain extent, they still have many shortcomings in mixing effect and efficiency. Especially when dealing with cosmetic raw materials with a high proportion of powder and water, traditional powder mixing uses a rotating shaft to drive the mixing blades for unidirectional mixing, which often makes it difficult to ensure uniform mixing of the raw materials and easily leads to unstable product quality.

[0004] In order to improve the uniformity of the mixing, it is currently proposed to put the disperser in a negative pressure state and rotate the mixed powder under the negative pressure state, such as a new cosmetic powder-in-water mixer with Chinese patent publication number CN209109085U, which includes a V-shaped disperser body, a solution feed pipe on the left side of the V-shaped disperser body, a powder feed pipe on the right side, and a mixing and stirring area at the bottom; a liquid booster pump and several first atomizing nozzles are provided at the left side of the solution feed pipe, the first atomizing nozzles are connected to the liquid booster pump, and a liquid injection peristaltic pump is provided in the solution feed pipe; a plurality of Second atomizing nozzle: a stirring device is provided in the mixing and stirring zone, a homogenizer probe connected to the homogenizer is provided on the side wall of the mixing and stirring zone, a discharge pipe is connected to the mixing and stirring zone, and a filter discharge valve is provided on the discharge pipe; the V-shaped disperser agitator body is provided with a vacuum pump and a vacuum pressure gauge, and the vacuum pump and the vacuum pressure gauge are both connected to the internal space of the V-shaped disperser agitator body; although the patent can greatly improve the uniformity of the mixed materials, the patent still has reservations on the specific structural design of the stirring device, and the working principle and construction details of the stirring device are not disclosed in detail, which to a certain extent limits its application and promotion in actual production.

[0005] Therefore, in view of this, the inventor proposes a cosmetic powder-in-water mixing device to solve the above technical problems. Summary of the invention

[0006] The object of the present invention is to provide a cosmetic powder-in-water mixing device to solve the problem that the existing powder mixing device has poor turbulence effect on powder due to unidirectional stirring, resulting in unstable adsorption oil content of the product.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A cosmetic powder-in-water mixing device comprises a V-shaped dispersing agitator body, the left side of the V-shaped dispersing agitator body is a solution feed pipe, the right side is a powder feed pipe, and the bottom is provided with a mixing and stirring zone; it also comprises a mixing drum arranged in the mixing and stirring zone and a rotating drum arranged in the mixing drum, the outer periphery of the rotating drum abuts against the inner wall of the mixing drum; A first stirring member, a second stirring member and a third stirring member are coaxially connected and rotated in the rotating drum, and the second stirring member rotates in the opposite direction to the first stirring member and the third stirring member; A fourth stirring member is disposed at the bottom of the rotating drum, and the fourth stirring member is fixed to the rotating drum; The invention also includes a driving member connected to the first stirring member, the third stirring member and the fourth stirring member, wherein the first stirring member and the third stirring member rotate along a first direction, and the second stirring member, the fourth stirring member and the rotating drum rotate along the second direction; The first direction and the second direction have opposite rotation directions.

[0008] Further, the fourth stirring member comprises a fourth connecting rod, a connecting ring and a fourth propeller fan, the fourth propeller fan and the connecting ring are fixedly arranged on the fourth connecting rod, and the fourth connecting rod is a hollow structure; The connecting ring is used to connect with the rotating drum; A first driven bevel gear is coaxially fixedly disposed on the bottom of the fourth connecting rod.

[0009] According to the above technical solution, during the stirring process, the fourth stirring member drives the drum to rotate together, and the fourth spiral fan, with its unique spiral shape, vigorously stirs the materials in the mixing and stirring area to ensure that the materials can be evenly mixed. At the same time, since the solution feed pipe will spray viscous refined water and volatile silicone oil, these materials may adhere to the inner wall of the mixing drum due to centrifugal force during the stirring process. When the drum rotates, the drum will be in close contact with the inner wall of the mixing drum and effectively scrape off the water-mixed powder adhering to the inner wall, which not only improves the stirring efficiency, but also avoids adhesion of the inner wall of the mixing drum, avoiding material waste and uneven stirring. Furthermore, the second stirring member includes a second connecting rod and a second propeller fan, the second propeller fan is fixedly sleeved on the outer circumference of the second connecting rod, and the second connecting rod is a hollow structure; The third stirring member comprises a third connecting rod and a third propeller fan, wherein the third propeller fan is fixedly sleeved on the outer periphery of the third connecting rod, and the third connecting rod is a hollow structure; The bottom of the third connecting rod passes through the fourth connecting rod and is coaxially fixedly connected to the second driven bevel gear, and the first driven bevel gear and the second driven bevel gear are coaxially arranged; A conversion member is provided between the second connecting rod and the third connecting rod, and the conversion member is rotatably installed in the rotating drum.

[0010] Further, the conversion member includes a mixing drum rotatably mounted in the rotating drum, wherein a first bevel gear, a second bevel gear and two third bevel gears are arranged in the mixing drum, the first bevel gear and the second bevel gear are symmetrically arranged along the height direction of the mixing drum, the two third bevel gears are arranged between the first bevel gear and the second bevel gear, and the two third bevel gears are respectively meshed with the first bevel gear and the second bevel gear; The first bevel gear is coaxially fixed to the second connecting rod, and the second bevel gear is coaxially fixed to the third connecting rod.

[0011] According to the above technical solution, the third stirring member includes a third connecting rod and a third spiral fan. During the stirring process, the third connecting rod rotates to drive the third spiral fan to rotate to mix the water-mixed powder. The present application cleverly arranges a first bevel gear, a second bevel gear and two third bevel gears inside the stirring drum. The first bevel gear is coaxially fixed with the second connecting rod, and the second bevel gear is coaxially fixed with the third connecting rod. When the third connecting rod rotates, it drives the second bevel gear to rotate, and the rotation of the second bevel gear drives the third bevel gear to rotate. Since the third bevel gear is meshed with the first bevel gear, the second bevel gear drives the first bevel gear through the third bevel gear. The bevel gear rotates to complete the conversion of the rotation direction, driving the second connecting rod and the second propeller fan to rotate in the opposite direction, ensuring that the third stirring member and the second stirring member stir in different directions. When the second stirring member and the third stirring member rotate in opposite directions, they will produce different fluid dynamic effects in the mixing and stirring area. This differential stirring method helps to break up the agglomeration and stratification between the powders and make the materials more fully mixed. Stirring in opposite directions can also produce stronger shear force and vortex, which help to disperse the powder into smaller particles, further improve the uniformity of the mixing, and enhance the stirring effect.

[0012] Furthermore, the first stirring member includes a stirring head and at least two stirring blades, each of the stirring blades is evenly installed around the stirring head, and each of the stirring blades can be turned over on the stirring head; A first connecting rod is fixedly arranged at the bottom of the stirring head, and the first connecting rod passes through the second connecting rod, the third connecting rod, and the fourth connecting rod is connected to a third driven bevel gear; The first driven bevel gear, the second driven bevel gear and the third driven bevel gear are coaxially arranged.

[0013] Further, the first stirring member further comprises a pushing arm, the pushing arm being arranged at the top of the stirring head, the pushing arm being provided with at least two hinged rods, each of the hinged rods being evenly distributed on the pushing arm, one end of the hinged rod being hinged to the stirring head, and the other end of the hinged rod being hinged to a corresponding one of the stirring blades; A push rod is fixedly arranged at the center position of the push arm. The push rod is located inside the second connecting rod and completely penetrates the second connecting rod. The push rod can rise or fall inside the second connecting rod.

[0014] According to the above technical scheme, first, the first stirring member is composed of a stirring head, stirring blades, a pushing arm, a hinged rod and a push rod. At least two stirring blades are evenly installed on the stirring head so that the stirring blades can be turned over on the stirring head. The pushing arm is arranged at the top of the stirring head, and a push rod is fixed at its center. During the stirring process, the first stirring member is connected to the driving member through the first connecting rod to realize rotational motion. When the stirring head starts to rotate, the stirring blades also rotate accordingly to mix the materials. At this time, due to the uniform distribution of the stirring blades, it can ensure that the materials are fully covered in the mixing drum. At the same time, the push rod can rise or fall in the second connecting rod under the action of the driving member. When the push rod rises or falls, it drives the stirring blades connected to it to turn over through the pushing arm, thereby changing the position angle of the stirring blades. This turning motion enables the stirring blades to produce more complex fluid dynamic effects during the stirring process, which helps to break the agglomeration and stratification between the materials. With the continuous rotation of the mixing head and the flipping of the mixing blades, the materials in the mixing drum are constantly subjected to the effects of eddy currents and shear forces. These forces can disperse the materials into smaller particles, further improving the uniformity of mixing. At the same time, due to the flipping motion of the mixing blades, the flow direction of the materials can be continuously changed, so that the materials form a more complex flow pattern in the mixing drum, further enhancing the mixing effect.

[0015] Further, the driving member includes a driving shell arranged at the bottom of the mixing drum, a first motor is arranged in the driving shell, a first driving rod is connected to the output shaft of the first motor, the first motor is fixedly arranged in the driving shell, and the first driving rod is rotatably connected in the driving shell; A first driving bevel gear and a second driving bevel gear are coaxially mounted on the first driving rod, the first driving bevel gear and the second driving bevel gear have different numbers of teeth, and the first driving bevel gear is meshed with the first driven bevel gear and the second driven bevel gear; The second driving bevel gear is meshed with the third driven bevel gear.

[0016] According to the above technical solution, the driving member is the power source of the entire stirring system, and it is mainly composed of a driving shell, a first motor, a first driving rod, a first active bevel gear, a second active bevel gear, and a driven bevel gear. First, the first motor is fixedly arranged in the driving shell, and its output shaft is connected to the first driving rod. When the first motor is started, it drives the first driving rod to rotate in the driving shell. The first driving rod is coaxially mounted with the first active bevel gear and the second active bevel gear. The two bevel gears have different numbers of teeth, so they have different transmission ratios. This design enables the first active bevel gear and the second active bevel gear to generate different speeds when rotating, thereby meeting the speed requirements of different stirring members in the stirring system. Next, the first active bevel gear is meshed with the first driven bevel gear and the second driven bevel gear. When the first driving rod rotates, the first active bevel gear will drive the first driven bevel gear and the second driven bevel gear to rotate. Since the first driven bevel gear is connected to the fourth stirring member and the rotating drum, and the second driven bevel gear is connected to the third stirring member, stirring of the material is achieved; at the same time, the second active bevel gear is meshed with the third driven bevel gear. When the first driving rod rotates, the second active bevel gear will also drive the third driven bevel gear to rotate, thereby driving the first stirring member to rotate. Since the first active bevel gear and the second active bevel gear can generate different speeds when rotating, the first stirring member, the second stirring member and the third stirring member will rotate at different speeds, further participating in the stirring process of the material.

[0017] Further, a driving unit is arranged in the driving shell, and the driving unit comprises a support seat fixedly arranged in the driving shell, two toothed rings are fixedly arranged in the supporting seat, two second gears are meshed in the two toothed rings, a second driving rod is rotatably connected at the center of the two toothed rings, the second driving rod is rotatably connected in the driving shell, a connecting shaft is fixedly arranged along the radial direction of the second driving rod, the connecting shaft is connected to one of the second gears, and a movable rod is hinged between the two second gears; A guide cylinder is fixedly arranged on the top of the support seat, a piston column is slidably arranged in the guide cylinder, and the bottom of the piston column is hinged to the movable rod.

[0018] Furthermore, a driving gear is coaxially fixedly provided on the first driving rod, a driven gear is fixedly provided on the second driving rod, and a tensioning belt is tensioned between the driving gear and the driven gear.

[0019] According to the above technical solution, inside the drive housing, the drive unit realizes the transmission and conversion of power through a series of precise mechanical structures. The support seat is firmly installed in the drive housing, and two toothed rings are fixedly arranged on it. The two toothed rings are independent of each other and mesh with two second gears inside respectively. The second gears can rotate freely in the toothed rings and transmit power through meshing with the toothed rings; the second drive rod passes through the center of the support seat and is fixedly connected to the connecting shaft thereon. The connecting shaft is connected to one of the second gears to ensure that the second drive rod can drive the second gear to rotate when it rotates. The two second gears are hinged by a movable rod to form a connecting rod mechanism. When the second drive rod rotates, a second gear is driven to rotate through the connecting shaft, and then the other second gear is driven to rotate in the opposite direction through the movable rod. At the top of the support seat, the guide cylinder provides a stable sliding track for the piston column. The bottom of the piston column is hinged with the movable rod. Therefore, when the movable rod swings due to the rotation of the second gear, the piston column will slide up and down in the guide cylinder, and the circular motion is converted into linear motion.

[0020] Furthermore, a plurality of clamping members are arranged on the outer periphery of the rotating drum, and the clamping members include two clamping plates, and a rubber strip is arranged between the two clamping plates.

[0021] According to the above technical solution, when the drum rotates, the rubber strip will be in close contact with the inner wall of the mixing drum, and with its elasticity and friction, it will effectively scrape off the water-mixed powder adhering to the inner wall, which not only improves the mixing efficiency, but also avoids adhesion to the inner wall of the mixing drum, avoiding material waste and uneven mixing.

[0022] Beneficial effects of the present invention: The solution of the present invention enters through the solution feed pipe on the left, and the powder enters through the powder feed pipe on the right, and they fall into the mixing and stirring zone at the bottom together. The driving member starts to work, driving the first stirring member, the third stirring member and the fourth stirring member to start rotating. Since the first stirring member and the third stirring member rotate in the first direction, and the second stirring member, the fourth stirring member and the rotating drum rotate in the second direction, this rotation in opposite directions can greatly enhance the fluidity and mixing effect of the material in the mixing and stirring zone. The rotation in opposite directions can form stronger shear force and vortex, which helps the material to reach a uniform mixing state faster, thereby improving the uniformity of mixing.

[0023] The driving gear on the first driving rod of the present invention is connected to the driven gear on the second driving rod through a tensioning belt. When the first motor drives the first driving rod to rotate, it not only drives the first bevel gear, the second bevel gear and the third bevel gear to rotate; it also drives the driven gear and the second driving rod to rotate through the tensioning belt, thereby transmitting power to the driving unit to realize the linkage of the entire stirring system.

DETAILED DESCRIPTION

[0027] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0029] This embodiment provides a cosmetic powder-in-water mixing device, such as Figures 1 to 12 As shown, the V-shaped dispersing stirrer body includes a solution feed pipe 1 on the left side of the V-shaped dispersing stirrer body, a powder feed pipe 2 on the right side, and a mixing and stirring zone at the bottom; a mixing drum 3 arranged in the mixing and stirring zone and a rotating drum 4 arranged in the mixing drum 3, and the outer periphery of the rotating drum 4 abuts against the inner wall of the mixing drum 3; specifically, as Figure 4As shown, a plurality of clamping members 41 are arranged on the periphery of the rotating drum 4, and the clamping members 41 include two clamping plates 411, and a rubber strip is arranged between the two clamping plates 411; since the solution feeding pipe 1 sprays viscous refined water and volatile silicone oil, when in contact with the powder, these water-mixed powders may adhere to the inner wall of the mixing drum 3 due to the centrifugal force during the stirring process, and when the rotating drum 4 rotates, the rubber strip on the rotating drum 4 will be in close contact with the inner wall of the mixing drum 3, and effectively scrape off the water-mixed powder adhered to the inner wall, which not only improves the stirring efficiency, but also avoids adhesion to the inner wall of the mixing drum 3, and avoids material waste and uneven stirring.

[0030] like Figure 4 , Figure 5 and Figure 6 As shown, a first stirring member 5, a second stirring member 6 and a third stirring member 7 are coaxially connected to the rotating drum 4, and the second stirring member 6 rotates in the opposite direction to the first stirring member 5 and the third stirring member 7; a fourth stirring member 8 is arranged at the bottom of the rotating drum 4, and the fourth stirring member 8 is fixed to the rotating drum 4; The device further comprises a driving member 9 connected with the first stirring member 5, the third stirring member 7 and the fourth stirring member 8. The driving member 9 is arranged at the bottom of the stirring drum 3. The first stirring member 5 and the third stirring member 7 rotate in the first direction, and the second stirring member 6, the fourth stirring member 8 and the rotating drum 4 rotate in the second direction; wherein the first direction is opposite to the second direction. When the device is working, the solution enters through the solution feeding pipe 1 on the left, and the powder enters through the powder feeding pipe 2 on the right, and falls into the stirring drum 3 in the mixing and stirring zone at the bottom together. The driving member 9 starts to work, driving the first stirring member 5, the third stirring member 7 and the fourth stirring member 8 to start rotating. Since the first stirring member 5 and the third stirring member 7 rotate in the first direction, and the second stirring member 6 and the fourth stirring member 8 and the rotating drum 4 rotate in the second direction, the rotation in opposite directions can greatly enhance the fluidity and mixing effect of the material in the mixing and stirring zone. The rotation in opposite directions can form stronger shear force and vortex, which helps the water-mixed powder to reach a uniform mixing state faster, thereby improving the uniformity of mixing.

[0031] As a preferred embodiment, Figure 6 As shown, the fourth stirring member 8 includes a fourth connecting rod 81, a connecting ring 82 and a fourth spiral fan 83. The fourth spiral fan 83 and the connecting ring 82 are fixedly arranged on the fourth connecting rod 81. The fourth connecting rod 81 is a hollow structure. The top of the connecting ring 82 is fixedly connected to the bottom of the rotating drum 4. During the stirring process, the fourth stirring member 8 drives the rotating drum 4 to rotate together, and the fourth spiral fan 83 stirs the water-mixed powder in the stirring drum 3 to ensure that the water-mixed powder can be evenly mixed. The bottom of the fourth connecting rod 81 is coaxially fixed with a first driven bevel gear 84.

[0032] As a preferred embodiment, the second stirring member 6 includes a second connecting rod 61 and a second propeller fan 62, the second propeller fan 62 is fixedly mounted on the outer periphery of the second connecting rod 61, and the second connecting rod 61 is a hollow structure; the third stirring member 7 includes a third connecting rod 71 and a third propeller fan 72, the third propeller fan 72 is fixedly mounted on the outer periphery of the third connecting rod 71, and the third connecting rod 71 is a hollow structure; the bottom of the third connecting rod 71 passes through the fourth connecting rod 81 and is coaxially fixedly connected with the second driven bevel gear 73, and the first driven bevel gear 84 is coaxially arranged with the second driven bevel gear 73; a conversion member 10 is arranged between the second connecting rod 61 and the third connecting rod 71, and the conversion member 10 is rotatably installed in the rotating drum 4.

[0033] Specifically, the conversion member 10 includes a mixing drum 3 rotatably mounted in a rotating drum 4, a first bevel gear 101, a second bevel gear 102 and two third bevel gears 103 are arranged in the mixing drum 3, the first bevel gear 101 and the second bevel gear 102 are symmetrically arranged along the height direction of the mixing drum 3, the two third bevel gears 103 are arranged between the first bevel gear 101 and the second bevel gear 102, and the two third bevel gears 103 are respectively meshed with the first bevel gear 101 and the second bevel gear 102; The first bevel gear 101 is coaxially fixed to the second connecting rod 61 , and the second bevel gear 102 is coaxially fixed to the third connecting rod 71 .

[0034] During the mixing process, the third connecting rod 71 rotates to drive the third propeller fan 72 to rotate to mix the water-mixed powder. The present application cleverly arranges a first bevel gear 101, a second bevel gear 102 and two third bevel gears 103 inside the mixing drum 3. The first bevel gear 101 is coaxially fixed with the second connecting rod 61, and the second bevel gear 102 is coaxially fixed with the third connecting rod 71. When the third connecting rod 71 rotates, it drives the second bevel gear 102 to rotate, and the rotation of the second bevel gear 102 drives the third bevel gear 103 to rotate. Since the third bevel gear 103 is meshed with the first bevel gear 101, the second bevel gear 102 is driven by the third bevel gear 103. The first bevel gear 101 is driven to rotate, completing the conversion of the rotation direction, and driving the second connecting rod 61 and the second propeller fan 62 to rotate in the opposite direction, ensuring that the third stirring member 7 and the second stirring member 6 are stirred in different directions. When the second stirring member 6 and the third stirring member 7 rotate in opposite directions, they will produce different fluid dynamic effects in the mixing and stirring area. This differential stirring method helps to break up the agglomeration and stratification between the powders, so that the water-mixed powder can be mixed more fully. Stirring in opposite directions can also produce stronger shear force and vortex, which help to disperse the powder into smaller particles, further improve the uniformity of the mixing, and enhance the stirring effect.

[0035] As a preferred embodiment, Fig. 9As shown, the first stirring member 5 includes a stirring head 51 and at least two stirring blades 52, each stirring blade 52 is evenly installed around the stirring head 51, and each stirring blade 52 can be flipped on the stirring head 51; in the present embodiment, the number of stirring blades 52 is four, which are evenly installed on the stirring head 51; of course, it can be understood that the number of stirring blades 52 is not limited to four, but may also be five, six or more.

[0036] A first connecting rod 53 is fixedly provided at the bottom of the stirring head 51, and the first connecting rod 53 passes through the second connecting rod 61, the third connecting rod 71 and the fourth connecting rod 81 and is connected to the third driven bevel gear 54; wherein the first driven bevel gear 84, the second driven bevel gear 73 and the third driven bevel gear 54 are coaxially arranged.

[0037] As a preferred embodiment, Fig. 9 As shown, the first stirring member 5 further includes a push arm 55, which is disposed on the top of the stirring head 51. The push arm 55 is provided with at least two hinged rods 56, and each hinged rod 56 is evenly distributed on the stirring head 51. In this embodiment, the number of the hinged rods 56 is the same as the number of the stirring blades 52, both of which are in the form of four. One end of the hinged rod 56 (i.e. Fig. 9 The top of the hinged rod 56 is hinged to the push arm 55, and the other end of the hinged rod 56 (i.e. Fig. 9 In the figure, the bottom of the hinged rod 56 is eccentrically hinged to the corresponding one of the stirring blades 52; a push rod 57 is fixedly provided at the center position of the push arm 55, and the push rod 57 is located inside the second connecting rod 61 and completely penetrates the second connecting rod 61. The push rod 57 can rise or fall inside the second connecting rod 61.

[0038] According to the above technical solution, the first stirring member 5 is composed of a stirring head 51, a plurality of stirring blades 52, a pushing arm 55, a hinged rod 56, a push rod 57 and other components. At least two stirring blades 52 are evenly installed on the stirring head 51, and the stirring blades 52 can be turned over on the stirring head 51. The pushing arm 55 is arranged on the top of the stirring head 51, and a push rod 57 is fixed at its center. During the stirring process, the first stirring member 5 is connected to the driving member 9 through the first connecting rod 53 to achieve rotational movement. When the stirring head 51 starts to rotate, the stirring blades 52 also rotate accordingly to mix the water-mixed powder. At this time, due to the uniform distribution of the stirring blades 52, it can ensure that the material is fully covered in the stirring barrel 3. At the same time, under the action of the driving member 9, the push rod 57 can rise or fall in the second connecting rod 61. When the push rod 57 rises or falls, it drives the stirring blade 52 connected thereto to change its angle through the push arm 55, thereby changing the transformation angle of the stirring blade 52. This angle flipping movement enables the stirring blade 52 to produce a more complex fluid dynamic effect during the stirring process, which helps to break up the agglomeration and stratification between materials. With the continuous rotation of the stirring head 51 and the flipping of the stirring blade 52, the material is continuously subjected to the action of eddy currents and shear forces in the mixing drum 3. These forces can disperse the powder into smaller particles, further improving the uniformity of the mixing; at the same time, due to the flipping movement of the stirring blade 52, the flow direction of the material can also be continuously changed, so that the water-mixed powder forms a more complex flow pattern in the mixing drum 3, further enhancing the mixing effect.

[0039] As a preferred embodiment, Figure 2 As shown, the driving member 9 includes a driving shell 91 arranged at the bottom of the mixing drum 3, a first motor 92 is arranged in the driving shell 91, a first driving rod 93 is connected to the output shaft of the first motor 92, the first motor 92 is fixedly arranged in the driving shell 91, and the first driving rod 93 is rotatably connected in the driving shell 91; a first driving bevel gear 94 and a second driving bevel gear 95 are coaxially mounted on the first driving rod 93, the first driving bevel gear 94 and the second driving bevel gear 95 have different numbers of teeth, the first driving bevel gear 94 is meshed with the first driven bevel gear 84 and the second driven bevel gear 73; the second driving bevel gear 95 is meshed with the third driven bevel gear 54.

[0040] According to the above technical solution, the first motor 92 is fixedly arranged in the driving housing 91, and its output shaft is connected to the first driving rod 93. When the first motor 92 is started, it drives the first driving rod 93 to rotate in the driving housing 91. The first driving rod 93 is coaxially mounted with a first active bevel gear 94 and a second active bevel gear 95. The two bevel gears have different numbers of teeth, so they have different transmission ratios. This design enables the first active bevel gear 94 and the second active bevel gear 95 to drive the corresponding mechanism to generate different speeds when rotating, thereby meeting the speed requirements of different stirring parts in the stirring system. The first active bevel gear 94 is meshed with the first driven bevel gear 84 and the second driven bevel gear 73. When the first driving rod 93 rotates, the first active bevel gear 94 will drive the first driven bevel gear 84 and the second driven bevel gear 73 to rotate. Since the first driven bevel gear 84 is connected to the fourth stirring member 8 and the rotating drum 4, and the second driven bevel gear 73 is connected to the third stirring member 7, when the third stirring member 7 rotates, it drives the second stirring member 6 to rotate in the opposite direction to achieve the stirring of the water-mixed powder; at the same time, the second active bevel gear 95 is meshed with the third driven bevel gear 54. When the first driving rod 93 rotates, the second active bevel gear 95 will also drive the third driven bevel gear 54 to rotate, and then drive the first stirring member 5 to rotate. Since the number of teeth of the first active bevel gear 94 and the second active bevel gear 95 are different, the first stirring member 5 can rotate at different speeds with the second stirring member 6 and the third stirring member 7, and further participate in the stirring process of the water-mixed powder.

[0041] As a preferred embodiment, Fig.10 , Fig.11 and Fig.12 As shown, a driving unit 96 is arranged in the driving shell 91, and the driving unit 96 includes a support seat 961 fixedly arranged in the driving shell 91, two toothed rings 962 are fixedly arranged in the supporting seat 961, two second gears 963 are meshed in the two toothed rings 962, a second driving rod 964 is rotatably connected at the center of the two toothed rings 962, the second driving rod 964 is rotatably connected in the driving shell 91, a connecting shaft is fixedly arranged along the radial direction of the second driving rod 964, the connecting shaft is connected to one of the second gears 963, and a movable rod 965 is hinged between the two second gears 963; A guide cylinder 966 is fixedly provided on the top of the support seat 961, a piston column 967 is slidably provided in the guide cylinder 966, and the bottom of the piston column 967 is hinged to the movable rod 965. A driving gear 971 is coaxially fixedly provided on the first driving rod 93, and a driven gear 972 is fixedly provided on the second driving rod 964. A tensioning belt 973 is tensioned between the driving gear 971 and the driven gear 972, and the driving gear 971 drives the driven gear 972 to rotate through the tensioning belt 973.

[0042] According to the above technical solution, the driving gear 971 on the first driving rod 93 is connected to the driven gear 972 on the second driving rod 964 through the tensioning belt 973. When the first motor 92 drives the first driving rod 93 to rotate, it not only drives the first bevel gear 101, the second bevel gear 102 and the third bevel gear 103 to rotate; it also drives the driven gear 972 and the second driving rod 964 to rotate through the tensioning belt 973, thereby transmitting power to the driving unit 96 to realize the linkage of the entire stirring system.

[0043] Inside the drive housing 91, the drive unit 96 realizes the transmission and conversion of power through a series of precise mechanical structures. The support seat 961 is firmly installed in the drive housing 91, and two toothed rings 962 are fixedly arranged thereon. The two toothed rings 962 are independent of each other and mesh with two second gears 963 inside respectively. The second gears 963 can rotate freely inside the toothed rings 962 and transmit power through the meshing with the toothed rings 962. The second drive rod 964 passes through the center of the support seat 961 and is fixedly connected to the connecting shaft thereon. The connecting shaft is connected to one of the second gears 963 to ensure that the second drive rod 964 can drive the second gear 963 to rotate when rotating. The two second gears 963 are hinged by a movable rod 965 to form a connecting rod mechanism. At the top of the support seat 961, the guide cylinder 966 provides a stable sliding track for the piston column 967. The bottom of the piston column 967 is hinged to the movable rod 965. Therefore, when the movable rod 965 swings due to the rotation of the second gear 963, the piston column 967 will slide up and down in the guide cylinder 966, converting circular motion into linear motion, driving the push rod 57 to move up and down, thereby realizing the angle change of the stirring blade 52.

[0044] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
