Abstract

The application discloses a preparation device of acne-removing, whitening and freckle-removing cream and relates to the technical field of cosmetic production equipment. The device comprises a tank body, a lifting mounting frame, filter cloth and a communication unit. The communication unit is installed on the top of the tank body and is used for connecting the inside of the tank body with an external condensing device. A lifting unit is used for driving the lifting mounting frame to move downward when the communication unit is in action. The lifting mounting frame is arranged. When the communication unit is in action, the lifting unit is triggered to move, and then the lifting mounting frame is driven to move downward. The lower end surface of the lifting mounting frame can scrape off the solute adhered to the inner wall of the tank body, so that the residue of the solute is reduced. The filter cloth is arranged. When the lifting mounting frame moves downward, the filter cloth is synchronously driven to move downward, so that the filter cloth has a compaction effect on the solute. In addition, under the action of extrusion force, the solvent can penetrate through the filter cloth, and the solute is left in the compression cavity because the solute particles are large.

Description

Technical Field

[0001] This invention relates to the field of cosmetic production equipment technology, and more specifically, to an apparatus and method for preparing an acne-removing, whitening, and spot-fading cream. Background Technology

[0002] In the production of cream-based cosmetics, the raw materials of each ingredient must first be crushed, then ground into powder, and mixed with solvents such as ethanol to form a mixture. The mixture is then distilled for extraction. During distillation, as the solvent evaporates, what remains is the solute of the mixture.

[0003] Current distillation equipment mainly uses heating to evaporate the solvent. During heating, the solvent content decreases as evaporation proceeds. Since the solvent and solute are mixed together, the solvent needs to be completely evaporated to achieve thorough separation of the solvent and solute. This results in low solvent and solute separation efficiency. In addition, when the mixture comes into contact with the distillation equipment, solute residue or adhesion to the inner wall of the distillation equipment is likely to occur. Although the solvent will separate from the solute as it evaporates, the adhesion between the solute and the distillation equipment makes it impossible to achieve rapid separation and cleaning, thus reducing the solute content after discharge to some extent. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an apparatus and method for preparing acne removal, whitening and spot fading cream. The technical problem to be solved by the present invention is that the distillation equipment in the prior art is prone to leaving solute residue on the inner wall, and the separation efficiency of solvent and solute needs to be improved.

[0019] An elastic abutting component is disposed within the connecting seat and elastically abuts against the sliding plug downwards, so that the lower end face of the sliding plug abuts against the top surface of the fixed block.

[0020] Furthermore, the resilient abutment component includes:

[0021] A stop ring, which is coaxially fixed to the upper opening of the connecting seat;

[0022] A spring is vertically installed inside the connecting seat, and its two ends in the direction of elastic force elastically abut against the sliding plug and the stop ring, respectively.

[0023] Furthermore, the sealing column is made of rubber.

[0024] Furthermore, the lifting unit includes:

[0025] Two hollow brackets are provided and are fixedly connected to the tank body from top to bottom;

[0026] A lead screw, the two ends of which are rotatably connected to the two hollow brackets along the length direction;

[0027] A threaded nut sleeve is fitted onto the lifting mounting frame, and the lead screw is threadedly engaged with the threaded nut sleeve.

[0035] Furthermore, the elastic swing arm is made of spring steel.

[0036] A method for preparing an acne-removing, whitening, and blemish-fading cream, applied to the apparatus for preparing the acne-removing, whitening, and blemish-fading cream as described above, comprising:

[0037] The mixture of raw materials and solvent is poured into the compression chamber of the tank, with the liquid level of the mixture below the filter cloth. The tank is heated using an electric heating device, which heats the mixture and causes the solvent to evaporate. The raw materials include: 10% by weight of traditional Chinese medicine ingredients, 80% by weight of base material, and 10% by weight of excipients. The traditional Chinese medicine ingredients include the following: Angelica dahurica, Bletilla striata, Poria cocos, calamine, Aconitum carmichaelii, Rosa rugosa, Paeonia lactiflora, and pearl powder. The base material includes the following: salicylic acid. The excipients include the following: stearic acid, glycerin, sorbitol, propylene glycol, polyethylene glycol, petrolatum, plant protein, alcohol, collagen, and alkali. The above raw materials are mixed together, then mixed with ultrasound, and then mixed with the relevant solvent to form a mixture.

[0038] As the solvent evaporates, the vapor pressure inside the evaporation chamber increases. When the vapor pressure increases to a certain level, it will trigger the connection unit to operate, allowing some of the vapor to enter the external condensation equipment, where the solvent vapor will be condensed and recovered.

[0039] When the connecting unit operates, it drives the lifting unit, which in turn drives the lifting mounting bracket to move downwards. When the lifting mounting bracket moves downwards, it scrapes the solute off the inner wall of the tank, and at the same time, it causes the filter cloth to move downwards and compress the mixture. During compression, the solvent will be filtered out by the filter cloth, while the solute particles are too large to pass through the filter cloth. As the filter cloth moves downwards intermittently, the physical separation of solvent and solute is achieved. Since the connecting unit operates continuously as evaporation proceeds, the filter cloth can move downwards intermittently and continuously, filtering solvent and solute. In addition, when the solute content is greater than the solvent content remaining in the compression chamber, the filter cloth compacts the solute.

[0040] The technical effects and advantages of this invention are as follows:

[0041] By setting up a lifting mounting frame, when the connecting unit is activated, the lifting unit will be triggered, which will drive the lifting mounting frame to move downward. The lower end face of the lifting mounting frame can scrape off the solute adhering to the inner wall of the tank, reducing the residue of the solute.

[0042] By setting up a filter cloth, when the lifting mounting frame moves downward, it simultaneously drives the filter cloth to move downward, thereby making the filter cloth compact the solute. In addition, under the action of extrusion pressure, because the solute particles are large, the solvent can pass through the filter cloth, while the solute is retained in the compression chamber.

[0043] By setting up a connecting unit, the vapor will only enter the external condensation equipment when the solvent vapor pressure in the evaporation chamber of the tank is relatively high. This reduces the heat loss inside the tank and improves the solvent evaporation efficiency inside the tank.

[0044] By setting the sliding plug to be pushed by the steam pressure, the sealing column gradually disengages from the insertion state with the through groove, so that the steam in the evaporation chamber can enter the connecting seat through the through groove, and then enter the external condensing equipment through the connecting groove of the sliding plug. When the steam pressure is low, the elastic abutment component will drive the sliding plug to move downward, so that the sliding plug and end face abut against the top surface of the fixed block, preventing the low temperature steam in the connecting seat from flowing back into the tank and causing heat loss in the tank.

[0045] By setting up an elastic swing arm and a lever, when the sliding plug moves downwards, the inclined surface of the lever contacts the inclined surface of the ratchet and slides relative to it. This causes the elastic swing arm to bend elastically toward the outside of the ratchet. As a result, when the sliding plug moves downwards, it does not drive the ratchet to rotate. Only when the sliding plug moves upwards will the upper surface of the lever contact the flat surface of the ratchet. As the sliding plug moves upwards, the lever moves the ratchet, causing the ratchet to rotate. This causes the first bevel gear and the second bevel gear to mesh and rotate, driving the filter cloth and the lifting mounting frame to move downwards. The structure is simple, requires no electrical components, has low cost, and requires no human intervention. Attached Figure Description

[0055] 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.

[0056] like Figures 1-8As shown in the figure, this embodiment discloses a preparation apparatus for an acne-removing, whitening, and blemish-fading cream, including a tank body 3 of a distillation vessel. An electric heating device (not shown in the figure) is installed at the bottom of the tank body 3. The tank body 3 is also provided with an inlet 4 and an outlet 15. The inlet 4 is connected to an external raw material conveying system via a pipeline. The raw material conveying system conveys a mixture of powdered raw materials and solvent to the inlet 4, and then from the inlet 4 into the tank body 3. Both the outlet 15 and the inlet 4 are equipped with... There is a control valve (not shown in the figure). A lifting mounting frame 13 is coaxially engaged inside the tank body 3. The lifting mounting frame 13 is hollow. In addition, the lifting mounting frame 13 can slide freely up and down inside the tank body 3. A filter cloth 12 is installed on the lifting mounting frame 13. The filter cloth 12 allows the solvent to pass through, while larger solute particles cannot pass through the filter cloth 12. In addition, the filter cloth 12 divides the interior of the tank body 3 into an evaporation chamber and a compression chamber from top to bottom. The feed port 4 and the discharge port 15 are connected to the compression chamber.

[0057] The mixture of powder raw materials and solvent is transported to the feed inlet 4 by the raw material conveying system and then enters the compression chamber of the tank 3. At this time, the liquid level of the mixture is lower than the filter cloth 12. Then the control valve on the feed inlet 4 is closed to isolate the inside of the tank 3 from the external environment. The electric heating equipment is started and works to heat the tank 3, thereby heating the mixture in the compression chamber.

[0058] In this embodiment, the raw materials of the acne-removing, whitening, and spot-fading cream include: 10% by weight of traditional Chinese medicine ingredients, 80% by weight of base material, and 10% by weight of excipients. The traditional Chinese medicine ingredients include the following raw materials: Angelica dahurica, Bletilla striata, Poria cocos, calamine, Aconitum carmichaelii, Rosa rugosa, Paeonia lactiflora, and pearl powder. The base material includes the following raw material: salicylic acid. The excipients include the following raw materials: stearic acid, glycerin, sorbitol, propylene glycol, polyethylene glycol, petrolatum, plant protein, alcohol, collagen, and alkali. The above raw materials are mixed together, then mixed by ultrasound, and then mixed with relevant solvents to form a mixture.

[0059] A hollow connecting seat 2 is screwed to the top of the tank body 3. The interior of the connecting seat 2 communicates with the connecting port opened at the top of the tank body 3. A connecting pipe 1, which communicates with the interior of the connecting seat 2, is screwed to the top of the connecting seat 2. The connecting pipe 1 is connected to the condensing equipment through a pipeline. A fixing block 17 is coaxially fixed to the lower opening of the connecting seat 2. A sliding plug 8, which can slide freely up and down, is coaxially engaged inside the connecting seat 2. Two through-hole-shaped connecting grooves 22 are opened on the end face of the sliding plug 8. A sealing post 18 is vertically fixed to the lower end face of the sliding plug 8. The fixed block 17 has a through groove for the sealing column 18 to pass through freely. The sliding plug 8 is located above the fixed block 17. A stop ring is coaxially fixedly connected to the upper opening of the connecting seat 2. A spring 7 is vertically installed inside the connecting seat 2. The two ends of the spring 7 elastically abut against the sliding plug 8 and the stop ring respectively. In the natural state, the spring 7 has a preload on the sliding plug 8, so that the lower end face of the sliding plug 8 abuts against the top face of the fixed block 17. At this time, the sealing column 18 is inserted into the through groove, so that the steam in the evaporation chamber cannot enter the interior of the connecting seat 2.

[0060] When the mixture is heated, the vapor from the evaporation of the mixture passes through the filter cloth 12 into the evaporation chamber, where it accumulates, causing the vapor pressure to increase. When the pressure reaches a certain level, it exerts a thrust on the sealing column 18, causing the sealing column 18 to move the sliding plug 8 upwards, disengaging it from the surface of the fixed block 17. When the sealing column 18 is completely disengaged from the through groove, the vapor enters the connecting seat 2 through the through groove 22, and then enters the external condensing equipment through the annular hole of the stop ring. The condensing equipment then processes the vapor. The evaporation chamber is condensed, and the solvent is then recovered. When the steam pressure in the evaporation chamber is less than the elastic force of the spring 7 on the sliding plug 8, the sliding plug 8 will be moved downward by the elastic force of the spring 7, so that the lower end face of the sliding plug 8 abuts against the top face of the fixed block 17. At the same time, the sealing column 18 is inserted into the through groove, so that the evaporation chamber and the inside of the connecting seat 2 are in an isolated communication state. In addition, the sealing column 18 is made of rubber, so that when the sealing column 18 is inserted into the through groove, the sealing effect on the evaporation chamber and the inside of the connecting seat 2 is better, so that the steam can be pressurized in the evaporation chamber.

[0061] A hollow bracket is coaxially welded to both the evaporation chamber and the compression chamber of the tank body 3. A lifting mounting frame 13 is located between the two hollow brackets. Ball bearings are embedded in each hollow bracket, and a lead screw 14 is inserted into the ball bearings of both hollow brackets. This allows the two ends of the lead screw 14 to be rotatably connected to the two hollow brackets along its length. A nut 16 is vertically embedded in the lifting mounting frame 13. The nut 16 is threaded onto the lead screw 14, and the lead screw 14 and nut 16 are threadedly engaged. That is, when the lead screw 14 rotates, it can drive the nut 16 to move axially along the lead screw 14. A first bevel gear 11 is sleeved on the upper end of the lead screw 14. A rotating shaft 6 is horizontally rotatably connected to the upper end of the tank body 3 via a mounting bearing. A second bevel gear 5 is sleeved on one end of the rotating shaft 6 that passes through the tank body 3. A bevel gear 11 and a second bevel gear 5 are in external meshing. In addition, a ratchet 9 is sleeved on the rotating shaft 6. Multiple ratchet teeth 10 are provided on the periphery of the ratchet 9. The ratchet teeth 10 are arranged in an array along the axial direction of the ratchet 9. A lifting rod 19 is coaxially fixedly connected to the end face of the sliding plug 8. The lifting rod 19 penetrates the fixing block 17, and the fixing block 17 has a through hole for the lifting rod 19 to pass freely. An L-shaped elastic swing arm 20 is welded to one end of the lifting rod 19 that extends into the evaporation chamber. The elastic swing arm 20 is made of spring steel. The horizontal section of the elastic swing arm 20 is welded to the lower end of the lifting rod 19, and a lever 21 is welded to the lower end of the vertical section of the elastic swing arm 20. The bottom of the lever 21 has an inclined surface that cooperates with the inclined surface of the ratchet teeth 10, so that the lever 21 and the ratchet teeth 10 cooperate.

[0062] When the solvent vapor in the evaporation chamber pushes the sliding plug 8 upward, the upward movement of the sliding plug 8 will drive the lifting rod 19 upward, causing the lifting rod 19 to drive the elastic swing arm 20 upward. When the elastic swing arm 20 moves upward, it will drive the lever 21 upward. When the lever 21 moves upward, the top surface of the lever 21 will generate an upward thrust on the flat surface of the ratchet 10, causing the lever 21 to drive one ratchet 10 to move upward, causing the ratchet 10 to drive the ratchet 9 to rotate. When the ratchet 9 rotates, it will drive the second bevel gear 5 to rotate. When the second bevel gear 5 rotates, due to the first bevel gear 11 It meshes with the second bevel gear 5, causing the second bevel gear 5 to rotate, which in turn drives the lead screw 14 to rotate. The rotation of the lead screw 14 will cause the lead screw sleeve 16 to move downward, causing the filter cloth 12 and the lifting mounting frame 13 to move downward for a fixed stroke. When the lifting mounting frame 13 moves downward, it can scrape the solute off the inner wall of the tank 3. At the same time, it causes the filter cloth 12 to move downward and compress the mixture. During compression, the solvent will be filtered out by the filter cloth 12, while the solute particles are too large to pass through the filter cloth 12. As the filter cloth 12 moves downward intermittently, the physical separation of solvent and solute is achieved.

[0063] When steam enters the connecting seat 2, the steam pressure in the evaporation chamber decreases. At this time, the elastic resisting force of spring 7 on sliding plug 8 is greater than the upward pushing force of steam on sliding plug 8, causing sliding plug 8 to move downward. When sliding plug 8 moves downward, lifting rod 19 moves downward, causing the inclined surface of the lever 21 to slide into contact with the inclined surface of the corresponding ratchet 10. The inclined surface of ratchet 10 exerts a squeezing force on lever 21 toward the radially outward side of ratchet 9, causing the vertical section of elastic swing arm 20 to elastically bend toward the radially outward side of ratchet 9. In this way, when sliding plug 8 moves downward, lever 21 will not drive ratchet 9 to rotate, thus avoiding the reciprocating up and down movement of lifting mounting bracket 13. In addition, because The steam pressure in the evaporation chamber increases rapidly, so in a short time, the steam pressure increases and drives the sliding plug 8 to move upward. As evaporation proceeds, the sliding plug 8 moves continuously, so the filter cloth 12 can move downward intermittently and continuously, filtering the solvent and solute. In addition, when the solute content is greater than the solvent content remaining in the compression chamber, the filter cloth 12 compacts the solute. Furthermore, a rotating handle is installed at one end of the rotating shaft 6 that extends out of the tank 3. After discharge, the rotating handle is manually rotated to rotate the rotating shaft 6, which in turn rotates the lead screw 14 and causes the filter cloth 12 to move upward and reset, facilitating the next distillation operation.

[0064] The working principle of this invention: The mixture of powder raw materials and solvent is transported to the feed inlet 4 by the raw material conveying system, and then enters the compression chamber of the tank 3. At this time, the liquid level of the mixture is lower than the filter cloth 12. Then the control valve on the feed inlet 4 is closed, so that the inside of the tank 3 is isolated from the external environment. The electric heating device is started, and the electric heating device works to heat the tank 3, thereby heating the mixture in the compression chamber.

[0065] When the mixture is heated, the vapor from the vaporization of the mixture passes through the filter cloth 12 and enters the evaporation chamber, where it accumulates and increases the vapor pressure. When the pressure reaches a certain level, it will exert a pushing force on the sealing column 18, causing the sealing column 18 to drive the sliding plug 8 upward, thus disengaging the sliding plug 8 from the surface of the fixed block 17. When the sealing column 18 is completely disengaged from the through groove, the vapor will enter the connecting seat 2 through the through groove, and then enter the external condensing equipment through the connecting groove 22 and the annular hole of the stop ring. The condensing equipment condenses the vapor and recovers the solvent. When the vapor pressure in the evaporation chamber is less than the elastic force of the spring 7 on the sliding plug 8, the sliding plug 8 will move downward under the elastic force of the spring 7, causing the lower end face of the sliding plug 8 to abut against the top surface of the fixed block 17. At the same time, the sealing column 18 is inserted into the through groove, thus isolating the evaporation chamber from the interior of the connecting seat 2.

[0066] When the solvent vapor in the evaporation chamber pushes the sliding plug 8 upward, the upward movement of the sliding plug 8 will drive the lifting rod 19 upward, causing the lifting rod 19 to drive the elastic swing arm 20 upward. When the elastic swing arm 20 moves upward, it will drive the lever 21 upward. When the lever 21 moves upward, the top surface of the lever 21 will generate an upward thrust on the flat surface of the ratchet 10, causing the lever 21 to drive one ratchet 10 to move upward, causing the ratchet 10 to drive the ratchet 9 to rotate. When the ratchet 9 rotates, it will drive the second bevel gear 5 to rotate. When the second bevel gear 5 rotates, due to the first bevel gear 11 It meshes with the second bevel gear 5, causing the second bevel gear 5 to rotate, which in turn drives the lead screw 14 to rotate. The rotation of the lead screw 14 will cause the lead screw sleeve 16 to move downward, causing the filter cloth 12 and the lifting mounting frame 13 to move downward for a fixed stroke. When the lifting mounting frame 13 moves downward, it can scrape the solute off the inner wall of the tank 3. At the same time, it causes the filter cloth 12 to move downward and compress the mixture. During compression, the solvent will be filtered out by the filter cloth 12, while the solute particles are too large to pass through the filter cloth 12. As the filter cloth 12 moves downward intermittently, the physical separation of solvent and solute is achieved.

[0067] When steam enters the connecting seat 2, the steam pressure in the evaporation chamber decreases. At this time, the elastic resisting force of spring 7 on sliding plug 8 is greater than the upward pushing force of steam on sliding plug 8, causing sliding plug 8 to move downward. When sliding plug 8 moves downward, lifting rod 19 moves downward, causing the inclined surface of the lever 21 to slide into contact with the inclined surface of the corresponding ratchet 10. The inclined surface of ratchet 10 exerts a squeezing force on lever 21 toward the radially outward side of ratchet 9, causing the vertical section of elastic swing arm 20 to elastically bend toward the radially outward side of ratchet 9. In this way, when sliding plug 8 moves downward, lever 21 will not drive ratchet 9 to rotate, thus avoiding the up-and-down reciprocating movement of lifting mounting bracket 13. In addition, because the steam pressure in the evaporation chamber increases rapidly, it can achieve the desired effect in a short time. The increased steam pressure drives the sliding plug 8 to move upwards. As evaporation proceeds, the sliding plug 8 moves continuously, causing the filter cloth 12 to move downwards intermittently and filter the solvent and solute. Additionally, when the solute content is greater than the solvent content remaining in the compression chamber, the filter cloth 12 compacts the solute. After distillation, the control valve on the outlet 15 is opened, allowing the gel-like solute to flow out from the outlet 15 for collection. Furthermore, a rotating handle is installed at one end of the rotating shaft 6 that extends out of the tank 3. After discharge, manually rotating the handle rotates the rotating shaft 6, causing the lead screw 14 to rotate and the filter cloth 12 to move upwards and reset, facilitating the next distillation operation.

A paddle (21) extending toward the ratchet (9) is fixed to the lower end of the elastic swing arm (20). The paddle (21) is used in conjunction with the ratchet (10).

9. The apparatus for preparing the acne-removing, whitening, and blemish-fading cream according to claim 8, characterized in that, The elastic swing arm (20) is made of spring steel.

10. A method for preparing an acne-removing, whitening, and blemish-fading cream, applied to the preparation apparatus for the acne-removing, whitening, and blemish-fading cream as described in claim 1, characterized in that, include: The mixture of raw materials and solvent is put into the compression chamber of the tank (3), and the liquid surface of the mixture is below the filter cloth (12). The tank (3) is heated by an electric heating device, so that the mixture is heated and the solvent is heated and evaporated. The raw materials include: 10% by weight of Chinese medicine ingredients, 80% by weight of base material and 10% by weight of excipients. The Chinese medicine ingredients include the following raw materials: Angelica dahurica, Bletilla striata, Poria cocos, calamine, Aconitum carmichaelii, Rosa rugosa, Paeonia lactiflora and pearl powder. The base material includes the following raw material: salicylic acid. The excipients include the following raw materials: stearic acid, glycerin, sorbitol, propylene glycol, polyethylene glycol, petrolatum, plant protein, alcohol, collagen and alkali. The above raw materials are mixed together and then mixed by ultrasound. Then they are mixed with the relevant solvent to form a mixture. As the solvent evaporates, the vapor pressure inside the evaporation chamber increases. When the vapor pressure increases to a certain level, it will trigger the connection unit to operate, allowing some of the vapor to enter the external condensation equipment, where the solvent vapor will be condensed and recovered. When the connecting unit operates, it will drive the lifting unit to operate, which in turn drives the lifting mounting bracket (13) to move downward. When the lifting mounting bracket (13) moves downward, it can scrape the solute off the inner wall of the tank (3) and at the same time make the filter cloth (12) move downward and compress the mixture. During compression, the solvent will be filtered out by the filter cloth (12), while the solute particles are too large to pass through the filter cloth (12). As the filter cloth (12) moves downward intermittently, the physical separation of solvent and solute is achieved. Since the connecting unit operates continuously as evaporation proceeds, the filter cloth (12) will be able to move downward intermittently and continuously, filtering the solvent and solute. In addition, when the solute content is greater than the solvent content remaining in the compression chamber, the filter cloth (12) will compact the solute.
