Description

Technical Field

[0001] This utility model belongs to the technical field of raw material mixing equipment, specifically a cosmetic raw material mixing and stirring device. Background Technology

[0002] Cosmetic raw materials are mostly composed of a variety of materials in the form of solid powders, pastes, and liquid solvents. The uniformity of raw material mixing, the precision of feeding, and lossless stirring directly determine the texture, stability, and effect of the finished cosmetic product, and are the core links in the cosmetic production process.

[0003] Currently, traditional cosmetic raw material mixing and stirring devices require pre-weighing of materials before addition, necessitating frequent transfers of raw materials. This cumbersome and time-consuming process significantly reduces production efficiency. Furthermore, in the mixing stage, existing devices often employ a single-structure stirring rod, resulting in limited mixing range and a tendency for powders and liquids to separate and clump together at the top, making rapid dispersal and mixing difficult. The bottom of the mixing tank is often curved, making it impossible for conventional stirring rods to precisely fit the bottom, leading to sedimentation and dead zones at the bottom, hindering effective mixing. Additionally, the raw materials tend to settle at the bottom under gravity, and a single stirring cycle cannot achieve sufficient circulation and mixing of all materials in the tank. Consequently, the uniformity of the raw material mixing fails to meet production standards, ultimately affecting the quality and stability of the finished cosmetic product.

[0004] Therefore, a cosmetic raw material mixing and stirring device is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a cosmetic raw material mixing and stirring device, which has the advantages of achieving precise quantitative mixing and efficient uniform mixing of cosmetic raw materials through automatic quantitative feeding of solid and liquid, graded stirring, and circulation reflux, thereby improving stirring efficiency and raw material utilization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cosmetic raw material mixing and stirring device, comprising a mixing tank, a discharge pipe at the bottom of the mixing tank, a cover plate fixed at the top of the mixing tank, a solid feeding component and a liquid feeding component respectively provided on the cover plate, a drive motor fixed at the center of the cover plate, a stirring shaft connected to the output shaft of the drive motor, an upper stirring rod, a middle stirring rod and a lower stirring rod respectively provided on the stirring shaft, the upper stirring rod being blade-shaped, the middle stirring rod being T-shaped, and the lower stirring rod being arc-shaped, an insulation shell being provided on one side of the mixing tank, a circulation pump being installed inside the insulation shell, one end of the circulation pump being connected to the discharge pipe of the mixing tank through a pipe, and the other end being connected to the top side of the mixing tank through a pipe, and an electric heating tube being provided on the inner wall of the mixing tank.

[0007] Preferably, the solid feeding assembly includes a feeding trough, a micro motor, a tilting plate, a weighing platform, and a guide pipe. The feeding trough is connected to the inner cavity of the mixing tank through the guide pipe. The micro motor is fixed on one side of the feeding trough, and the output shaft of the micro motor is connected to the tilting plate. The weighing platform is mounted on the tilting plate.

[0008] Preferably, the liquid feeding assembly includes a metering cylinder, a liquid level sensor, and a liquid feed pipe. The metering cylinder is connected to the inner cavity of the mixing tank through the liquid feed pipe, and the liquid level sensor is vertically arranged inside the metering cylinder.

[0009] Preferably, the solid feeding assembly and the liquid feeding assembly are symmetrically arranged on both sides of the drive motor, and both the guide pipe and the liquid feed pipe are equipped with solenoid valves.

[0010] Preferably, one end of the stirring rod is provided with a scraper, which is attached to the inner wall of the mixing tank.

[0011] Preferably, the bottom of the inner cavity of the mixing tank is arc-shaped, and the arc matches the arc of the lower stirring rod.

[0012] Preferably, the inner wall of the mixing tank is provided with a jacket, and the electric heating tube is evenly coiled in the jacket.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of solid feeding components and liquid feeding components, allows for real-time quantitative weighing of solid raw materials directly on the weighing platform of the tilting plate after they are fed into the feeding trough. After liquid raw materials are injected into the measuring cylinder, the liquid level sensor monitors the liquid level in real time to achieve automatic quantitative weighing, which greatly reduces the difficulty of feeding operations and improves feeding efficiency.

[0015] 2. This utility model is equipped with an upper stirring rod, a middle stirring rod, and a lower stirring rod on the stirring shaft. The upper stirring rod can quickly disperse the added powder and liquid raw materials, preventing powder from flying and liquid from clumping on the surface. The middle stirring rod has strong shearing ability, which can fully stir the raw materials in the middle layer of the tank. At the same time, the scraper at its end is closely attached to the inner wall of the mixing tank and rotates synchronously with the stirring shaft to continuously scrape off the raw materials adhering to the tank wall, avoiding uneven mixing and waste caused by raw materials sticking to the wall. The lower stirring rod is precisely matched with the arc-shaped bottom of the mixing tank, which can efficiently push and tumble the materials at the bottom of the tank, improving the mixing quality of the raw materials.

[0016] 3. This utility model, through the circulation pump, can promptly extract the material deposited at the bottom of the tank during mixing and transport it to the top of the tank to re-participate in the stirring, forming a continuous material circulation and avoiding uneven mixing of raw materials caused by the sedimentation of materials due to gravity.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The following describes an embodiment of this utility model based on its overall structure.

[0025] like Figures 1 to 5As shown, this utility model provides a cosmetic raw material mixing and stirring device, including a mixing tank 1. A discharge pipe 2 is provided at the bottom of the mixing tank 1 for discharging the material after mixing. A cover plate 3 is fixed to the top of the mixing tank 1. A solid feeding component 4 and a liquid feeding component 5 are respectively provided on the cover plate 3 for adding solid and liquid raw materials, respectively. A drive motor 6 is fixed at the center of the cover plate 3. A stirring shaft 7 is connected to the output shaft of the drive motor 6. An upper stirring rod 8, a middle stirring rod 9, and a lower stirring rod 10 are respectively provided on the stirring shaft 7. The mixing tank 1 has a blade-shaped design, a T-shaped middle stirring rod 9, and an arc-shaped lower stirring rod 10, forming a three-dimensional layered stirring structure with no dead corners. A heat-insulating shell 11 is provided on one side of the mixing tank 1, and a circulation pump 12 is installed inside the heat-insulating shell 11. One end of the circulation pump 12 is connected to the discharge pipe 2 of the mixing tank 1 through a pipe, and the other end is connected to the top side of the mixing tank 1 through a pipe, forming a bottom-pull and top-return circulation system to prevent raw material sedimentation. An electric heating tube 13 is provided on the inner wall of the mixing tank 1 to achieve temperature control inside the tank.

[0026] In this embodiment, the solid feeding assembly 4 includes a feeding trough 41, a micro motor 42, a tilting plate 43, a weighing platform 44, and a guide pipe 45. The feeding trough 41 is connected to the inner cavity of the mixing tank 1 through the guide pipe 45. The micro motor 42 is fixed on one side of the feeding trough 41, and the output shaft of the micro motor 42 is connected to the tilting plate 43. The weighing platform 44 is installed on the tilting plate 43. Solid cosmetic raw materials are put into the feeding trough 41 of the solid feeding assembly 4 and fall onto the weighing platform 44 on the tilting plate 43 for real-time and accurate weighing. When the weight of the solid raw materials reaches the preset ratio, the micro motor 42 drives the tilting plate 43 to tilt, and the solid raw materials fall through the guide pipe 45. The solenoid valve on the guide pipe 45 controls the on / off state and quantitatively feeds the solid raw materials into the mixing tank 1.

[0027] The liquid feeding assembly 5 includes a metering cylinder 51, a liquid level sensor 52, and a liquid feed pipe 53. The metering cylinder 51 is connected to the inner cavity of the mixing tank 1 through the liquid feed pipe 53. The liquid level sensor 52 is vertically installed inside the metering cylinder 51. Liquid cosmetic raw materials are injected into the metering cylinder 51 of the liquid feeding assembly 5. The vertically installed liquid level sensor 52 inside the metering cylinder 51 monitors the liquid level height of the liquid raw materials in real time to achieve accurate quantification of the liquid raw materials. After quantification, the liquid raw materials are sent into the mixing tank 1 through the liquid feed pipe 53 under the control of a solenoid valve.

[0028] Solid feeding assembly 4 and liquid feeding assembly 5 are symmetrically arranged on both sides of drive motor 6. Solenoid valves are installed on both guide pipe 45 and liquid feed pipe 53 to ensure that solid and liquid raw materials fall evenly from both sides of the top of mixing tank 1, avoiding the accumulation of raw materials on one side.

[0029] A scraper 14 is provided at one end of the stirring rod 9. The scraper 14 is attached to the inner wall of the mixing tank 1. The scraper 14 rotates with the stirring shaft 7 to continuously scrape off the raw materials adhering to the inner wall of the mixing tank 1, so as to avoid the raw materials sticking to the wall and leaving residue.

[0030] The bottom of the inner cavity of the mixing tank 1 is arc-shaped, and the arc matches the arc of the lower stirring rod 10. The lower stirring rod 10 matches the arc of the bottom of the tank, pushing and stirring the high-viscosity raw material deposited at the bottom of the tank, eliminating the dead corner of the stirring at the bottom of the tank.

[0031] The inner wall of the mixing tank 1 is provided with a jacket, and the electric heating tube 13 is evenly coiled in the jacket to uniformly heat the raw materials in the tank and maintain a constant temperature, so as to meet the temperature process requirements for mixing, dissolving and emulsifying cosmetic raw materials.

[0032] The working principle and process of a cosmetic raw material mixing and stirring device: When mixing cosmetic raw materials, solid cosmetic raw materials are put into the feed trough 41 of the solid feeding component 4 and fall onto the weighing platform 44 on the tilting plate 43 for real-time and accurate weighing. When the weight of the solid raw material reaches the preset ratio, the micro motor 42 drives the tilting plate 43 to tilt, and the solid raw material falls through the guide pipe 45. The solenoid valve on the guide pipe 45 controls the on and off of the flow and quantitatively feeds it into the mixing tank 1. Liquid cosmetic raw materials are injected into the metering cylinder 51 of the liquid feeding component 5. The metering cylinder 51 is vertically... The liquid level sensor 52 monitors the liquid level in real time to achieve precise quantification. The quantified liquid material is then fed into the mixing tank 1 via the liquid feed pipe 53 under the control of a solenoid valve. The solid feed assembly 4 and liquid feed assembly 5 are symmetrically distributed on both sides of the drive motor 6, ensuring that the solid and liquid materials fall evenly from both sides of the top of the mixing tank 1, preventing accumulation on one side. When the materials are being stirred and mixed, the drive motor 6 starts, rotating the stirring shaft 7. The upper stirring rod 8, middle stirring rod 9, and lower stirring rod 10 on the stirring shaft 7 rotate synchronously, achieving layered stirring. The blade-shaped upper stirring rod 8 disperses and initially mixes the raw materials in the upper part of the mixing tank 1, preventing powder raw materials from flying and liquid raw materials from clumping on the surface; the middle stirring rod 9 strongly shears and fully stirs the raw materials in the middle layer of the tank, while the scraper 14 at the end of the middle stirring rod 9, which is attached to the tank wall, rotates with the shaft to continuously scrape off the raw materials adhering to the inner wall of the mixing tank 1, avoiding raw materials sticking to the wall and leaving residue; the lower stirring rod 10 matches the curvature of the arc-shaped tank bottom, pushing and tumbling the high-viscosity raw materials deposited at the bottom of the tank, eliminating the dead zones in the stirring at the bottom of the tank, and the circulating pump 12 works synchronously during mixing, through pipelines to... Material is extracted from the discharge pipe 2 at the bottom of mixing tank 1 and then transported back to the top side of mixing tank 1, allowing the material to flow and be remixed repeatedly, improving the mixing uniformity and emulsification effect of cosmetic raw materials. At the same time, the electric heating tube 13 in the jacket of mixing tank 1 is powered on to uniformly heat the raw materials in the tank and maintain a constant temperature, meeting the temperature process requirements for mixing, dissolving and emulsifying cosmetic raw materials. After the raw materials are mixed, the circulation pump 12 is turned off and the valve of the discharge pipe 2 is opened. With the pushing action of the arc-shaped tank bottom and the arc-shaped lower stirring rod 10, it is easy to discharge the raw materials after mixing, which is convenient and practical.
