Description

Technical Field

[0001] This invention relates to the field of cosmetic production equipment technology, specifically to a multi-channel automatic feeding vacuum emulsification reaction device. Background Technology

[0002] Emulsification is the process by which a liquid is uniformly dispersed into two immiscible liquids as extremely small droplets. Emulsification is a liquid-liquid interface phenomenon; two immiscible liquids, such as oil and water, separate into two layers in a container, with the less dense oil on top and the denser water on the bottom. If a suitable surfactant is added and vigorous stirring is applied, the oil is dispersed in the water, forming an emulsion. This process is called emulsification. Emulsions are the most widely used dosage form in cosmetics, ranging from watery fluids to viscous creams. Therefore, discussions of emulsions are of paramount importance for the research, production, preservation, and use of cosmetics.

[0003] In the cosmetics production process, emulsification is generally carried out using a vacuum emulsification mixing tank. Before emulsification, the raw materials to be emulsified need to be put into the emulsification tank manually or automatically. This pouring method puts the raw materials into the emulsification tank all at once, which puts a heavy load on the stirring components inside the emulsification tank. Sufficient stirring time is required to achieve uniform discharge of the emulsion, resulting in a high time cost for the emulsification stage. Summary of the Invention

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figure 1 As shown, the present invention provides a multi-channel automatic feeding vacuum emulsification reaction device, comprising:

[0049] Reaction vessel 10, used to form a chamber for emulsification reaction;

[0050] A vacuum pumping component 20 is connected to the reaction vessel 10, and the vacuum pumping component 20 is used to maintain a negative pressure environment in the reaction vessel 10;

[0051] The feeding component 30 is connected to the feed inlet of the reaction tank 10. The feeding component 30 is used to premix the raw materials of the emulsification reaction and then spray them into the reaction tank 10.

[0052] A swing-arm stirring component 40 is disposed inside the reaction vessel 10, and the swing-arm stirring component 40 is used to perform secondary mixing of the sprayed raw materials;

[0053] Based on the existing structure of the emulsification reaction device described above, one of the features of this embodiment of the invention is that the feeding component 30 can premix the emulsified raw materials before they enter the reaction tank 10.

[0054] In actual production, since the reaction tank 10 needs to maintain a vacuum state of different vacuum levels during the processing, and different ingredients need to be added at different time points according to requirements, the embodiments of the present invention are mainly aimed at the raw materials added at intermediate points, that is, the interior of the reaction tank 10 has a certain amount of emulsified raw materials before feeding.

[0055] Therefore, the feeding component 30 can premix the raw materials to be fed between feeding stages, thereby reducing the stirring load of the stirring components in the reaction tank 10. At the same time, the feeding component 30 sends the raw materials into the reaction tank 10 in the form of spraying, which can improve the uniformity of the distribution of the raw materials in the reaction tank 10 and further improve the quality of the emulsion.

[0056] Specifically, the feeding component 30 includes a feeding channel 31, a premixing mechanism 32, and an intermittent spraying mechanism 33;

[0057] Multiple feeding channels 31 are provided, and the feeding channels 31 are used to provide raw materials for the emulsification reaction;

[0058] The ends of the multiple feeding channels 31 are all connected to the premixing mechanism 32, which is used to premix multiple raw materials;

[0059] The feed end of the intermittent spraying mechanism 33 is connected to the premixing mechanism 32, and the discharge end of the intermittent spraying mechanism is located inside the reaction tank 10. The feeding spraying mechanism is used to release the premixed raw materials into the reaction tank in multiple quantitative increments. This quantitative release method avoids the load on the stirring components caused by adding all the raw materials at once.

[0060] Furthermore, the intermittent spraying mechanism 33 includes a collection pipe 331, an intermittent opening and closing component, and a rotating power component 332;

[0061] A discharge port is provided on the premixing mechanism 32, one end of the collecting pipe 331 is rotatably installed in the discharge port, and the other end of the collecting pipe 331 is arranged inside the reaction tank 10 along the inlet.

[0062] Multiple spray holes 333 are provided on the outer wall of the collecting pipe 331, and the intermittent opening and closing mechanism is used to intermittently open the spray holes 333;

[0063] The rotating power component 332 is connected to the material collection pipe 331, and the rotating power component 332 is used to drive the material collection pipe 331 to rotate so that the spraying hole 333 can rotate and spread material.

[0064] The specific structure of the rotating power component 332 here can be that a gear is set on the outside of the collecting pipe 331, and the rotation is driven by the gear meshing, or other direct or indirect methods can be used to achieve rotation.

[0065] The intermittent opening and closing component mentioned here can be any mechanism that can realize the intermittent opening and closing of the spray nozzle 333, such as a solenoid valve. In this embodiment of the invention, the intermittent opening and closing component includes a plug 334 and a power rod 335.

[0066] The collecting pipe 331 includes an installation section rotatably installed at the feed inlet of the reaction tank 10 and a working section connected to the installation section. The installation section has a circular cross-section, and the working section has a polygonal cross-section. The plug 334 is installed against the wall inside the working section. Due to the polygonal design, the plug 334 cannot rotate automatically along the inner wall of the working section but can only rotate with the working section. The thickness of the plug 334 is greater than the diameter of the spray hole 333. The power rod 335 is connected to the plug 334. The power rod 335 is used to drive the plug 334 to move up and down so that the plug 334 intermittently closes the spray hole 333.

[0067] The intermittent opening and closing mechanism formed by the blockage 334 and the power rod 335 here, while completing the intermittent opening operation of the spray nozzle 333, also has another function:

[0068] As the plug 334 moves downward, the structure formed by the plug 334 and the collecting pipe 331 resembles a syringe. The raw material added to the premixing mechanism 32 can enter the collecting pipe 331 and be released into the reaction vessel 10 as the plug 334 moves downward.

[0069] As the blockage 334 moves upward, it can push the raw material in the collecting pipe 331 back into the premixing mechanism 32, thereby forming an upward jet in the premixing mechanism 32, thus adding the raw material in the premixing mechanism 32 to be mixed evenly.

[0070] The up-and-down movement of the power rod 335 is achieved by sequentially connecting a connecting rod 336, a linkage rod 337, and a flipping plate 338 to the end of the power rod 335.

[0071] The connecting rod 336 is rotatably mounted on the end of the power rod 335. One end of the linkage rod 337 is hinged to the connecting rod 336, and the other end of the linkage rod 337 is connected to the flipping plate 338. The flipping plate is horizontally arranged inside the reaction tank 10, and the middle of the flipping plate is rotatably connected to the inner wall of the reaction tank 10 through a rotating shaft 339.

[0072] The rotating shaft 339 is connected to a driving structure, which is used to drive the rotating shaft 339 to rotate. The linkage rod 337 is used to convert the rotation and flipping of the flipping plate into the up and down movement of the power rod 335.

[0073] In this embodiment of the invention, the premixing mechanism 32 includes a mixing chamber 321, a solid release box 322, and a stirring assembly. Since the raw materials are divided into solid raw materials and liquid raw materials in the emulsification reaction, the solid raw materials transported through the feeding channel 31 are easily left on the inner wall of the pipe. Therefore, multiple feeding channels 31 are connected to the mixing chamber 321, and the feeding channels 31 are used to provide liquid raw materials to the mixing chamber 321.

[0074] The solid release box 322 is disposed inside the mixing chamber 321, and a plurality of leakage holes are densely opened on the solid release box 322. The solid release box 322 is used to hold solid raw materials.

[0075] The stirring assembly is disposed inside the mixing chamber 321. The stirring assembly is used to accelerate the liquid flow in the mixing chamber 321 so that the solid raw material in the solid release box 322 is quickly dispersed into the liquid raw material.

[0076] The size of the drain hole can be adjusted according to the particle size of the solid raw material. The drain hole can prevent some clumps of solid raw material from entering the emulsification tank.

[0077] For agglomerated solid raw materials, in this embodiment of the invention, the stirring assembly includes a grinding pestle 323 and a stirring blade 324. The grinding pestle 323 is rotatably mounted inside the solid release box 322. The bottom of the solid release box 322 is connected to the mixing chamber 321 by a spring 325 so that the solid release box 322 can fit tightly against the bottom of the grinding pestle 323. The stirring blade 324 is mounted on the outer periphery of the grinding pestle 323 so that the stirring blade 324 can rotate together with the grinding pestle 323.

[0078] When the grinding pestle 323 rotates, a device similar to a traditional abrasive mechanism is formed between the grinding pestle 323 and the solid release box 322. The rotating grinding pestle can accelerate the crushing and dispersion of solid raw materials. When the material in the solid release box 322 becomes less and less, the spring 325 moves upward, and the solid raw materials in the solid release box 322 can always be in close contact with the bottom of the grinding pestle.

[0079] In addition, a second feature of this embodiment of the invention is that the swing-arm stirring component 40 can swing up and down to switch stirring angles. Specifically, the swing-arm stirring component 40 includes a telescopic stirring paddle 41. One end of the telescopic stirring paddle 41 is hinged to the power rod 335. An annular groove 11 is provided on the inner wall of the reaction tank 10. The other end of the telescopic stirring paddle 41 is slidably installed in the groove 11. When the power rod 335 moves up and down, the telescopic stirring paddle 41 can swing up and down.

[0080] Furthermore, the cross-section of the groove 11 is C-shaped, and a spherical ball bearing 42 matching the groove 11 is provided at the end of the telescopic stirring paddle 41. The telescopic stirring paddle 41 is slidably installed inside the groove 11 through the spherical ball bearing 42, so that when the power rod 335 rotates, the spherical ball bearing 42 moves in a circular motion along the groove 11.

[0081] Because the length of the telescopic stirring component changes during oscillation, such as Figure 2 As shown, the telescopic stirring paddle 41 includes a first stirring section 411 connected to the spherical ball bearing 42 and a second stirring section 412 rotatably connected to the power rod 335. An inner groove 413 for slidingly mounting the first stirring section 411 is provided in the second stirring section 412. Multiple auxiliary stirring sections 414 are installed on the outer circumferential surface of the first stirring section 411. An opening 415 for the auxiliary stirring sections 414 to extend from the outer wall of the second stirring section 412 is provided. The area of ​​the opening 415 is larger than the cross-section of the auxiliary stirring section 414. When the first stirring section 411 moves along the inner groove 413, the auxiliary stirring sections 414 can move synchronously, that is, the auxiliary stirring sections 414 vibrate in a direction perpendicular to the first stirring section 411, thereby accelerating the collision of raw materials in the reaction tank 10 and improving emulsification efficiency.

[0082] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
