Description

Technical Field

[0001] The present application relates to the technical field of cosmetic production, and in particular to an emulsifying stirring device and process for cosmetic production. Background Art

[0002] Emulsification refers to the physical process of adding an emulsifier between two immiscible liquids (such as oil and water) to form a uniform dispersion system. The role of the emulsifier is to reduce the interfacial tension between oil and water, so that the oil droplets are dispersed into fine oil droplets in the water, thereby forming a stable emulsion. Emulsions are widely used in the fields of cosmetics, food industry, pharmaceuticals, and chemical preparations. By selecting different emulsifiers and preparation conditions, the properties of the emulsion can be adjusted to meet the needs of specific uses.

[0003] In the production and preparation process of cosmetics, it is usually necessary to use an emulsifier to shear, disperse and impact the cosmetic raw materials to make the cosmetic raw materials more delicate, promote the blending of oil and water, and then evenly mix the various active ingredients, thickeners, moisturizers, etc. in the cosmetics to ensure the performance of the final product.

[0004] Referring to the Chinese patent document with announcement number CN118142407B and announcement date July 30, 2024, entitled "An emulsifier for homogenizing and stirring for use in a cosmetics production workshop", the device can form a strong negative pressure zone in its central area through the rotation of the crushing wheel, so that the material is sucked into the working chamber for continuous shearing, thereby improving the emulsification efficiency.

[0005] According to the above technical solution, when the cosmetic raw materials are directly poured into the preparation container for emulsification and stirring, the water phase material and the oil phase material in the cosmetic raw materials have poor fusion, and the water phase material and the oil phase material will be separated (that is, part of the oil phase material will float on the upper layer of the water phase material). In this case, when the subsequent emulsification and stirring work is carried out, the cosmetic raw materials in the middle of the preparation container closer to the stirring shaft have better fluidity, and the water phase material and the oil phase material here are more likely to mix, while the cosmetic raw materials at the edge of the preparation container farther away from the stirring shaft have poor fluidity, and the water phase material and the oil phase material here are difficult to mix effectively, which may lead to inconsistent overall shear dispersion of the cosmetic raw materials in the preparation container, thereby affecting the final emulsification effect of the cosmetic raw materials. Summary of the invention

[0006] In view of this, the present application provides an emulsifying stirring device and process for cosmetic production, which is mainly used to solve the problem of stratification of water phase materials and oil phase materials affecting the final emulsification quality of cosmetic raw materials.

[0007] In order to solve the above technical problems, the present application provides an emulsifying stirring device and process for cosmetic production.

[0008] In the first aspect, the present application provides an emulsifying stirring device for cosmetic production, comprising a stirring barrel, a sealing cover installed at the top opening of the stirring barrel, and a stirring mechanism arranged in the middle of the sealing cover; the stirring mechanism comprises a driving motor arranged in the middle of the sealing cover, the bottom end of the driving motor output shaft is fixedly connected to the stirring shaft, the outer rotating sleeve of the stirring shaft is provided with a sleeve, the bottom end of the sleeve is threadedly connected to a threaded tube, and a first through hole is opened at the top of the threaded tube, and a second through hole is opened in the middle of the threaded tube, the stirring impeller arranged in the middle of the stirring shaft and the axial flow turbine arranged at the bottom are both located inside the threaded tube; a driving cylinder is arranged on the sealing cover, and a guide tube sleeved on the outside of the sleeve is arranged at the actuator end of the driving cylinder, and the threaded tube is axially slidably connected to the inside of the guide tube, an oil inlet pipe connected to the inner cavity of the guide tube and capable of vertical extension and contraction is arranged on the sealing cover, and a plurality of material distribution pipes are connected in the middle of the guide tube.

[0009] By adopting the above technical solution, the stirring impeller and the axial flow turbine can pre-disperse the oil phase material and the water phase material before they come into contact, and then the oil phase material and the water phase material can be mixed inside the threaded tube in the form of offset. Compared with the method of directly pouring the oil phase material into the water phase material, the possibility of stratification between the two can be reduced.

[0010] Optionally, the inner top wall of the cover is rotatably connected to a stirring frame that can be extended and retracted vertically, and the inner top wall of the cover is provided with a transmission component for driving the stirring frame to rotate synchronously when the stirring shaft rotates.

[0011] By adopting the above technical solution, the stirring frame can rotate synchronously with the stirring shaft through the cooperation of the transmission component, so as to assist in stirring the cosmetic raw materials in the stirring barrel.

[0012] Optionally, the transmission assembly includes a large diameter gear ring arranged on the top of the stirring frame, a small diameter gear is arranged on the upper end of the stirring shaft, and the top wall inside the cover is rotatably connected to a transmission gear that meshes with the large diameter gear ring and the small diameter gear at the same time.

[0013] By adopting the above technical solution, the stirring frame can be rotated under the step-by-step meshing of the small-diameter gear, the transmission gear and the large-diameter gear ring.

[0014] Optionally, the distribution pipe is horizontally arranged and fixedly connected to the telescopic frame at the bottom of the stirring frame, and multiple distribution pipes are connected to the middle part of the guide pipe through a rotating joint in a rotating sleeve manner.

[0015] By adopting the above technical solution, the cosmetic raw materials can be more evenly distributed in the mixing barrel when passing through the distribution tube.

[0016] Optionally, a servo motor is provided on the cover, a driving gear is provided at the bottom end of the output shaft of the servo motor, a driven gear is provided at the top of the sleeve, a flexible scraper capable of abutting against the inner wall of the threaded tube is provided in the middle of the stirring shaft, and the flexible scraper is located above the stirring impeller.

[0017] By adopting the above technical solution, the axial-flow turbine inside the threaded tube can be exposed after it moves upward, and the flexible scraper can push out most of the cosmetic raw materials that may remain on the inner wall of the threaded tube, so as to reduce the burden of subsequent cleaning work.

[0018] In a second aspect, the present application provides an emulsification stirring process for cosmetic production, which is applied to an emulsification stirring device for cosmetic production described in the first aspect, and the emulsification stirring process includes:

[0019] S1, firstly, the water phase material is fed into the mixing barrel through the top opening of the mixing barrel, and then the top opening of the mixing barrel is sealed with the help of a cover. In this state, the oil inlet pipe is connected to the first through hole, and the material distribution pipe is connected to the second through hole;

[0020] S2, the driving motor then drives the stirring shaft and the axial flow turbine to rotate. Under the action of the axial flow turbine, the water phase material inside the stirring barrel will be sheared and dispersed and transferred upward through the bottom opening of the threaded tube;

[0021] S3, the oil phase material is sent into the threaded pipe through the oil inlet pipe and the first through hole, and then the oil phase material is transferred downward along the threaded pipe until the water phase material and the oil phase material contact to form a counter-attack and mix, and then the water phase material and the oil phase material are discharged into the mixing barrel through the second through hole and the distribution pipe.

[0022] By adopting the above technical solution, compared with the method of directly pouring the oil phase material into the water phase material, the water phase material and the oil phase material can be mixed more effectively after contacting in the form of offset, thereby reducing the probability of stratification of the water phase material and the oil phase material.

[0023] Optionally, in S3, the stirring impeller rotates along with the stirring shaft, and the stirring impeller corresponds to the position of the first through hole, so that the stirring impeller shears and disperses the oil phase material before the water phase material and the oil phase material contact, thereby improving the mixing effect of the water phase material and the oil phase material.

[0024] Optionally, after S3 is completed, the introduction of the oil-phase material is stopped, and then the cylinder is driven to move the guide tube and the distribution tube upward until the first through hole is connected to the distribution tube, and the distribution tube rises to the liquid level position inside the mixing barrel. During this process, the oil inlet pipe will adaptively shrink as the guide tube moves upward, and then the driving motor drives the mixing shaft and the axial flow turbine to reverse, so that the oil-phase material that may remain at the liquid level position passes through the distribution tube, the first through hole and the threaded tube in turn and is transferred from the bottom opening of the threaded tube to the middle of the mixing barrel, which is conducive to the full mixing of the oil-phase material and the water-phase material.

[0025] By adopting the above technical solution, in the subsequent emulsification and stirring process, the oil phase material that may remain at the liquid surface can be transferred downward, forcing the oil phase material to contact the water phase material, thereby promoting the mixing of the oil phase material with the water phase material again.

[0026] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Before the oil phase material and the water phase material come into contact, the two can be pre-dispersed, and then the oil phase material and the water phase material are brought into contact in a counter-action manner, so as to promote the mixing of the oil phase material and the water phase material, reduce the probability of stratification of the water phase material and the oil phase material, and can transfer the oil phase material that may remain at the liquid surface downward during the subsequent emulsification and stirring process, which is conducive to the full mixing of the oil phase material and the water phase material.

[0028] 2. In the emulsification and stirring process of cosmetic raw materials, the use of multi-stage stirring can increase the mixing rate of water-phase materials and oil-phase materials in the cosmetic raw materials, and through the setting of the distribution pipe, the cosmetic raw materials can be more evenly distributed in the stirring barrel, further improving the mixing effect of water-phase materials and oil-phase materials.

[0029] 3. After the emulsification and stirring of the cosmetic raw materials are completed, the axial-flow turbine hidden inside the threaded tube can be exposed, and at the same time, most of the cosmetic raw materials that may remain on the inner wall of the threaded tube can be pushed out, which is conducive to the subsequent cleaning work.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 6 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0038] In the first aspect, the present application provides an emulsifying and stirring device for cosmetic production, which adopts the following technical solution:

[0039] Reference Figure 1 and Figure 2 This embodiment provides an emulsifying stirring device for cosmetic production, comprising a base, a stirring barrel 1, a cover 11, a stirring mechanism 2 and a feeding mechanism. The base is provided with a placement groove for the stirring barrel 1 to be embedded, and the cover 11 is arranged at the execution end of the built-in cylinder of the base. When the built-in cylinder of the base is running, the cover 11 will move up and down accordingly to realize the opening and closing of the top opening of the stirring barrel 1; the stirring mechanism 2 is arranged in the middle of the cover 11, and is used to stir the cosmetic raw materials; the feeding mechanism is arranged on the cover 11, and is used to feed the oil phase material into the stirring barrel 1.

[0040] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The stirring mechanism 2 includes a driving motor 21, a stirring shaft 22, a sleeve 23, a threaded tube 24, a first through hole 25, a second through hole 26, a stirring impeller 27 and an axial flow turbine 28. The driving motor 21 is arranged in the middle of the cover 11, the stirring shaft 22 is fixedly connected to the bottom end of the output shaft of the driving motor 21, the sleeve 23 is rotatably sleeved on the outside of the stirring shaft 22, the threaded tube 24 is threadedly connected to the bottom end of the sleeve 23, the first through hole 25 and the second through hole 26 are respectively opened at the top and the middle of the threaded tube 24, the stirring impeller 27 and the axial flow turbine 28 are respectively arranged in the middle and the bottom of the stirring shaft 22, and the stirring impeller 27 and the axial flow turbine 28 are both located inside the threaded tube 24.

[0041] Reference Figure 4 and Figure 5 The feeding mechanism includes a driving cylinder 3, a guide pipe 31, an oil inlet pipe 32 and a material distribution pipe 33. The driving cylinder 3 is arranged on the cover 11, the guide pipe 31 is fixedly connected to the execution end of the driving cylinder 3 and sleeved on the outside of the sleeve 23, and the guide pipe 31 is axially slidably sleeved on the outside of the threaded pipe 24; the oil inlet pipe 32 is arranged on the cover 11 and communicated with the inner cavity of the guide pipe 31, and the oil inlet pipe 32 can be adaptively vertically extended and retracted as the guide pipe 31 rises and falls; a plurality of material distribution pipes 33 are arranged, and each of the material distribution pipes 33 is connected to the middle of the guide pipe 31.

[0042] When the emulsification and stirring of the cosmetic raw materials are carried out, the aqueous phase material is first fed into the stirring barrel 1 through the top opening of the stirring barrel 1, and then the cover 11 is buckled on the top opening of the stirring barrel 1. In this state, the oil inlet pipe 32 is connected to the first through hole 25, and the material distribution pipe 33 is connected to the second through hole 26.

[0043] Then, the driving motor 21 drives the stirring shaft 22 and the axial-flow turbine 28 to rotate. Under the action of the axial-flow turbine 28, negative pressure is generated inside the threaded tube 24 where the axial-flow turbine 28 is located, so that the water-phase material inside the stirring barrel 1 is sheared and dispersed by the axial-flow turbine 28 and transferred upward through the bottom opening of the threaded tube 24; at the same time, the oil-phase material is fed into the threaded tube 24 through the oil inlet pipe 32 and the first through hole 25, and the oil-phase material is broken up by the stirring impeller 27 rotating with the stirring shaft 22, and then the oil-phase material is transferred downward along the threaded tube 24 and contacts the water-phase material to form a counter-attack, so that the oil-phase material and the water-phase material are mixed, and then the preliminarily mixed water-phase material and oil-phase material are discharged into the stirring barrel 1 through the second through hole 26 and the distribution pipe 33.

[0044] After the oil phase material is completely introduced into the mixing barrel 1, due to the property of the oil phase material itself that it will float on the surface of the water phase material, the air cylinder 3 can be driven to drive the guide tube 31 and the distribution tube 33 to move upward until the first through hole 25 is connected to the distribution tube 33, and at this time the distribution tube 33 will rise to the liquid level inside the mixing barrel 1. Then the driving motor 21 drives the mixing shaft 22 and the axial flow turbine 28 to reverse, so that the negative pressure direction generated in the inner cavity of the threaded tube 24 is reversed, so that the oil phase material that may remain at the liquid level passes through the distribution tube 33, the first through hole 25 and the threaded tube 24 in sequence and is transferred from the bottom opening of the threaded tube 24 to the middle of the mixing barrel 1, forcing the oil phase material to contact the water phase material again, which is conducive to the full mixing of the oil phase material and the water phase material.

[0045] Reference Figure 3 and Figure 4 The cover 11 is provided with an auxiliary stirring member for auxiliary stirring of the cosmetic raw materials, and the auxiliary stirring member includes a stirring frame 4 and a transmission assembly 5. The stirring frame 4 is rotatably connected to the top wall inside the cover 11, and the stirring frame 4 can adaptively vertically extend and retract as the guide tube 31 rises and falls; the transmission assembly 5 includes a large-diameter gear ring 51, a small-diameter gear 52 and a transmission gear 53, the large-diameter gear ring 51 is arranged on the top of the stirring frame 4, the small-diameter gear 52 is arranged on the upper end of the stirring shaft 22, the transmission gear 53 is rotatably connected to the top wall inside the cover 11, and the transmission gear 53 can be meshed and connected with the large-diameter gear ring 51 and the small-diameter gear 52 at the same time.

[0046] During the rotation of the stirring shaft 22, through the step-by-step transmission of the small-diameter gear 52, the transmission gear 53 and the large-diameter gear ring 51, the stirring frame 4 can rotate at a speed lower than that of the stirring shaft 22 and in a rotation direction different from that of the stirring shaft 22, thereby assisting in stirring the cosmetic raw materials in the stirring barrel 1 and improving the mixing rate of the water phase material and the oil phase material in the cosmetic raw materials.

[0047] Reference Figure 2 and Figure 3 The distribution pipe 33 is horizontally arranged and fixedly connected to the telescopic frame at the bottom of the stirring frame 4, and multiple distribution pipes 33 are connected to the middle part of the guide pipe 31 by a rotating sleeve through a rotating joint 6; in addition, the outlet of the horizontally arranged distribution pipe 33 is close to the distal position of the stirring barrel 1, and the outlet of the longitudinally arranged distribution pipe 33 is close to the proximal position of the stirring barrel 1.

[0048] When the stirring frame 4 rotates following the stirring shaft 22 , the distribution tube 33 will also rotate around the stirring shaft 22 . At the same time, due to the difference in the positions of the outlets of each distribution tube 33 , the cosmetic raw materials can be more evenly distributed in the stirring barrel 1 .

[0049] Reference Figure 1 , Figure 3 and Figure 6A servo motor 7 is arranged on the cover 11, a driving gear 71 is arranged at the bottom end of the output shaft of the servo motor 7, a driven gear 72 is arranged at the top of the sleeve 23, a flexible scraper 73 which can abut against the inner wall of the threaded tube 24 is arranged in the middle of the stirring shaft 22, and the flexible scraper 73 is located above the stirring impeller 27.

[0050] After the emulsification and stirring of the cosmetic raw materials are completed, the servo motor 7 drives the driving gear 71 to rotate, and the sleeve 23 rotates through the cooperation of the driven gear 72. At this time, the threaded tube 24 moves upward due to the threaded connection relationship between itself and the sleeve 23 and the axial sliding connection relationship between itself and the guide tube 31, so that the axial flow turbine 28 at the bottom end of the stirring shaft 22 is exposed, and the flexible scraper 73 can push out most of the cosmetic raw materials that may remain on the inner wall of the threaded tube 24 during its upward movement, which is conducive to the subsequent cleaning work.

[0051] The implementation principle of an emulsifying and stirring device for cosmetic production in the embodiment of the present application is as follows:

[0052] When the emulsification and stirring of the cosmetic raw materials are carried out, the aqueous phase material is first fed into the stirring barrel 1 through the top opening of the stirring barrel 1, and then the cover 11 is buckled on the top opening of the stirring barrel 1. In this state, the oil inlet pipe 32 is connected to the first through hole 25, and the material distribution pipe 33 is connected to the second through hole 26.

[0053] Then, the driving motor 21 drives the stirring shaft 22 and the axial flow turbine 28 to rotate. Under the action of the axial flow turbine 28, negative pressure is generated inside the threaded tube 24 where the axial flow turbine 28 is located, so that the water phase material inside the stirring barrel 1 is sheared and dispersed by the axial flow turbine 28 and transferred upward through the bottom opening of the threaded tube 24.

[0054] At the same time, the oil phase material is fed into the threaded tube 24 through the oil inlet pipe 32 and the first through hole 25, and the oil phase material will be broken up by the stirring impeller 27 rotating along with the stirring shaft 22, and then the oil phase material is transferred downward along the threaded tube 24 and contacts with the water phase material to form a counter-attack, so that the oil phase material and the water phase material are mixed, and then the preliminarily mixed water phase material and oil phase material are discharged into the stirring barrel 1 through the second through hole 26 and the distribution pipe 33.

[0055] After the oil phase material is completely introduced into the mixing barrel 1, due to the property of the oil phase material itself that it will float on the surface of the water phase material, the air cylinder 3 can be driven to drive the guide tube 31 and the distribution tube 33 to move upward until the first through hole 25 is connected to the distribution tube 33, and the distribution tube 33 will rise to the liquid level inside the mixing barrel 1. Then the driving motor 21 drives the mixing shaft 22 and the axial flow turbine 28 to reverse, so that the negative pressure direction generated in the inner cavity of the threaded tube 24 is reversed, so that the oil phase material that may remain at the liquid level passes through the distribution tube 33, the first through hole 25 and the threaded tube 24 in sequence and is transferred from the bottom opening of the threaded tube 24 to the middle of the mixing barrel 1, forcing the oil phase material to contact the water phase material again.

[0056] In a second aspect, the present application provides an emulsification stirring process for cosmetic production, which is applied to an emulsification stirring device for cosmetic production in the first aspect, and the emulsification stirring process includes:

[0057] S1, firstly, the water phase material is fed into the mixing barrel 1 through the top opening of the mixing barrel 1, and then the top opening of the mixing barrel 1 is sealed with the help of the cover 11. In this state, the oil inlet pipe 32 is connected to the first through hole 25, and the material distribution pipe 33 is connected to the second through hole 26;

[0058] S2, the driving motor 21 then drives the stirring shaft 22 and the axial flow turbine 28 to rotate. Under the action of the axial flow turbine 28, the water phase material inside the stirring barrel 1 will be sheared and dispersed and transferred upward through the bottom opening of the threaded tube 24;

[0059] S3, the oil phase material is sent into the threaded tube 24 through the oil inlet pipe 32 and the first through hole 25, and then the oil phase material is transferred downward along the threaded tube 24 until the water phase material and the oil phase material contact to form a counter-attack and mix, and then the water phase material and the oil phase material are discharged into the mixing barrel 1 through the second through hole 26 and the distribution pipe 33.

[0060] In S3, the stirring impeller 27 rotates along with the stirring shaft 22, and the stirring impeller 27 corresponds to the position of the first through hole 25, so that the stirring impeller 27 shears and disperses the oil phase material before the water phase material and the oil phase material contact, thereby improving the mixing effect of the water phase material and the oil phase material.

[0061] After S3 is completed, the introduction of the oil phase material is stopped, and then the cylinder 3 is driven to drive the guide tube 31 and the distribution tube 33 to move upward until the first through hole 25 is connected to the distribution tube 33, and the distribution tube 33 rises to the liquid level position inside the mixing barrel 1. During this process, the oil inlet pipe 32 will adaptively shrink as the guide tube 31 moves upward, and then the driving motor 21 drives the stirring shaft 22 and the axial flow turbine 28 to reverse, so that the oil phase material that may remain at the liquid level position passes through the distribution tube 33, the first through hole 25 and the threaded tube 24 in turn and is transferred from the bottom opening of the threaded tube 24 to the middle of the mixing barrel 1, which is conducive to the full mixing of the oil phase material and the water phase material.

[0062] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.

In this state, the oil inlet pipe (32) is connected to the first through hole (25), and the material distribution pipe (33) is connected to the second through hole (26); S2, the driving motor (21) then drives the stirring shaft (22) and the axial flow turbine (28) to rotate, and under the action of the axial flow turbine (28), the water phase material inside the stirring barrel (1) is sheared and dispersed and transferred upward through the bottom opening of the threaded tube (24); S3, the oil phase material is fed into the threaded tube (24) through the oil inlet pipe (32) and the first through hole (25), and then the oil phase material is transferred downward along the threaded tube (24) until the water phase material and the oil phase material contact each other to form a counter-action and mix, and then the water phase material and the oil phase material are discharged into the mixing barrel (1) through the second through hole (26) and the distribution pipe (33); the stirring impeller (27) rotates along with the stirring shaft (22), and the stirring impeller (27) corresponds to the position of the first through hole (25), so that the stirring impeller (27) shears and disperses the oil phase material before the water phase material and the oil phase material contact each other, thereby improving the mixing effect of the water phase material and the oil phase material; After S3 is completed, the introduction of the oil phase material is stopped, and then the cylinder (3) is driven to drive the guide pipe (31) and the distribution pipe (33) to move upward until the first through hole (25) is connected to the distribution pipe (33), and the distribution pipe (33) rises to the liquid level position inside the stirring barrel (1). During this process, the oil inlet pipe (32) will adaptively shrink as the guide pipe (31) moves upward, and then the driving motor (21) drives the stirring shaft (22) and the axial flow turbine (28) to reverse, so that the oil phase material remaining at the liquid level position passes through the distribution pipe (33), the first through hole (25) and the threaded pipe (24) in sequence and is transferred from the bottom opening of the threaded pipe (24) to the middle of the stirring barrel (1), which is conducive to the full mixing of the oil phase material and the water phase material.
