Description

Technical Field

[0001] This utility model relates to the field of cosmetic production technology, and in particular to a raw material mixing device for cosmetic production. Background Technology

[0002] In the cosmetics manufacturing industry, thorough and uniform mixing of raw materials is a key step in ensuring product quality and performance. In existing cosmetic raw material mixing devices, the mixing shaft and its mixing plate are the core mixing components, undertaking the important task of mixing and dispersing various raw materials to achieve the ideal reaction state. However, in actual mixing operations, the mixing shaft and mixing plate face significant heat generation problems.

[0003] Specifically, once the mixing device is started, the mixing shaft begins to rotate at high speed, driving the mixing plate to violently agitate the raw material mixture. During this process, the mixing shaft and mixing plate must overcome not only the internal friction between the raw materials but also the external friction between the mixing plate and the raw materials. The continuous action of these frictional forces causes the mixing shaft and mixing plate to continuously generate heat during mixing. As the mixing time increases, the heat gradually accumulates, causing the temperature of the mixing shaft and mixing plate to rise continuously. This heating phenomenon of the mixing shaft and mixing plate can have a series of adverse effects on the mixing effect of cosmetic raw materials and product quality. First, excessively high temperatures may cause some temperature-sensitive cosmetic raw materials to denature, decompose, or undergo chemical reactions, thereby altering the chemical composition and physical properties of the raw materials and affecting the stability and effectiveness of the final product. For example, some raw materials containing active ingredients may lose their activity at high temperatures, resulting in a significant reduction in product efficacy. Second, increased temperature can also cause changes in the viscosity of the raw materials, increasing the difficulty of mixing, reducing mixing uniformity, and potentially leading to insufficient mixing in certain areas or material stratification, further affecting the consistency of product quality. In addition, prolonged operation at high temperatures will accelerate the wear of the stirring shaft and stirring plates, shorten their service life, and increase the maintenance cost and replacement frequency of the equipment.

[0004] In existing improved technologies, for example, patent number CN112452226A discloses a stirring device and stirring method for cosmetic production, which uses pipe cooling water for heat absorption and cooling. However, in this solution, the cooling pipe is inserted from the bottom and fixedly installed. In order to adapt, a placement groove is opened at the bottom of the mixing rod for stirring. This can easily cause the material being stirred to enter its interior, affecting the pipe or stirring. At the same time, it cannot absorb heat from the stirring plate on the stirring shaft (mixing rod), which cannot meet the usage requirements.

[0005] Therefore, the applicant proposes a raw material mixing device for cosmetic production to solve the problem. Utility Model Content

[0006] This invention provides a raw material mixing device for cosmetic production, which solves the problems mentioned in the background.

[0007] To solve the above-mentioned technical problems, this utility model provides a raw material mixing device for cosmetic production, including a mixing box. An L-shaped frame is installed on the top of the mixing box. A mixing assembly is connected to the L-shaped frame and the mixing box. The mixing assembly includes a mixing shaft rotatably mounted on the mixing box. The mixing shaft has a hollow design and mixing plates arranged on both sides. A condenser tube is installed inside the mixing shaft. The condenser tube is fixedly inserted through the mixing plates. One end of the top of the condenser tube is connected to a pipe joint one fixedly installed on the top of the mixing shaft. The pipe joint one is rotatably and sealingly connected to a pipe joint two. The pipe joint two is fixed on the L-shaped frame and is connected to a pump body through a conduit. The pump body is installed on the top of a cooling water tank installed on one side of the mixing box. The mixing tank is equipped with a reflux assembly, which is used to return water from the other end of the condenser tube to the cooling water tank.

[0008] Preferably, the portion through which the condenser tube is fixed to the stirring plate has a U-shaped design, and the stirring plate has a row of round holes.

[0009] Preferably, the inner wall of the stirring shaft is fixed with a heat-conducting and heat-absorbing aluminum ring plate, and the aluminum ring plate is fixedly connected to the condenser tube.

[0010] Preferably, the reflux assembly includes an annular groove fixed to the top of the mixing tank, the annular groove surrounding the mixing shaft inside, the outer side of the annular groove being higher than the inner side, a return L-shaped pipe installed on the top of the condenser tube relative to the other end of the connecting pipe joint, the return L-shaped pipe extending out of the mixing shaft, and the bottom outlet of the return L-shaped pipe being close to the bottom of the annular groove, and a return pipe connected to the cooling water tank on the outer wall of the annular groove.

[0011] Preferably, a rubber gasket is bonded to the side wall of the inner ring of the annular groove. The rubber gasket slides with low resistance against the outer wall of the stirring shaft, thus providing a sealing effect.

[0012] Preferably, the vertical portion of the return water L-shaped pipe is fixed with an arc plate, and the two sides of the arc plate are close to but not in contact with the inner wall of the annular groove.

[0013] Preferably, the L-shaped frame is connected to the stirring shaft by a drive assembly, including a motor fixed on one side of the L-shaped frame, the bottom output shaft of the motor being connected to a pulley, and the pulley and the stirring shaft together having a belt body wound around it; The belt body passes through the corresponding opening of the L-shaped frame, and the outer wall of the stirring shaft is provided with limiting ring plates at the upper and lower ends of the belt body winding position.

[0014] Compared with related technologies, the raw material mixing device for cosmetic production provided by this utility model has the following beneficial effects: Compared to the bottom-insertion installation method of the comparative patent, the present invention, through the segmented U-shaped design of the condenser tube, can more comprehensively cover the stirring plate, ensuring full contact between the cooling water and the stirring plate, maximizing heat removal, preventing the stirring shaft and stirring plate from being affected by overheating, and avoiding denaturation, decomposition, or chemical reaction of some temperature-sensitive cosmetic raw materials due to high temperature. At the same time, the built-in design of the condenser tube eliminates the need for slotting at the bottom of the stirring shaft, preventing material from entering and ensuring stable operation of the device. Compared with the comparative technology, it has better stability.

[0015] In terms of optimized reflux design, the annular groove is combined with the L-shaped return water pipe design. The L-shaped return water pipe discharges cooling water during rotation, allowing the water to fall precisely into the groove and avoid splashing and overflow. The water then flows smoothly back to the cooling water tank through the return pipe, achieving stable circulation of cooling water and ensuring continuous stirring. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1-7 This utility model provides a raw material mixing device for cosmetic production, including a mixing tank 1. An L-shaped frame 11 is installed on the top of the mixing tank 1. A mixing assembly 2 is connected to the L-shaped frame 11 and the mixing tank 1. The mixing assembly 2 includes a mixing shaft 21 rotatably mounted on the mixing tank 1. The mixing shaft 21 has a hollow design and mixing plates 22 arranged on both sides. A condenser tube 25 is installed inside the mixing shaft 21. The condenser tube 25 is fixedly inserted through the mixing plates 22. One end of the top of the condenser tube 25 is connected to a pipe joint 23 fixedly installed on the top of the mixing shaft 21. The pipe joint 23 is rotatably and sealingly connected to a pipe joint 24. The pipe joint 24 is fixed on the L-shaped frame 11 and is connected to a pump body 13 through a conduit. The pump body 13 is installed on the top of a cooling water tank 12 installed on one side of the mixing tank 1. A return flow assembly 4 is installed on the mixing tank 1 for returning water from the other end of the condenser tube 25 to the cooling water tank 12.

[0020] Through the unique design of the stirring component 2, during stirring, materials are added into the stirring tank 1, and then the existing drive equipment causes the stirring shaft 21 to rotate, driving the stirring plates 22 arranged on both sides to fully stir the materials (at a uniform and moderate speed), so that the various raw materials are mixed, dispersed and reach the ideal reaction state. During the stirring process, as the stirring shaft 21 and the stirring plates 22 continuously overcome the internal friction between the raw materials and the external friction between the stirring plates 22 and the raw materials, a large amount of heat is generated, causing the temperature of the stirring shaft 21 and the stirring plates 22 to rise. At this time, the condenser pipe 25 installed inside the stirring shaft 21 and fixedly inserted through the stirring plates 22 begins to play a key role. The pump body 13 starts, and the cooling water in the cooling water tank 12 is transported through the conduit to the pipe joint 24 fixed on the L-shaped frame 11. As the pipe joint 23 and the pipe joint 24 rotate... With a sealed connection, cooling water can smoothly enter the pipe joint 23 at the top of the stirring shaft 21 and further flow into the condenser pipe 25. The cooling water flows in the condenser pipe 25, absorbing the heat generated by the friction between the stirring shaft 21 and the stirring plate 22, thus achieving effective cooling. The part of the condenser pipe 25 that is fixedly inserted into the stirring plate 22 is reasonably designed to ensure that the cooling water can fully contact the stirring plate 22, carrying away heat to the maximum extent and preventing the stirring shaft 21 and the stirring plate 22 from being affected by overheating, thus avoiding denaturation, decomposition or chemical reaction of some temperature-sensitive cosmetic raw materials due to high temperature. This ensures the stability of the chemical composition and physical properties of the raw materials, and ensures the stability and effectiveness of the final product. In an optional embodiment, the output source of the pipe joint 24 can be replaced by a fan instead of a pump. In some cases where the heat is not high, air cooling can be used instead, resulting in lower losses. This will not be elaborated here.

[0021] After heat exchange, the cooling water, whose temperature has increased, flows out from the other end of the top of the condenser tube 25. At this time, the reflux component 4 installed on the mixing tank 1 starts to work and finally flows back smoothly into the cooling water tank 12, realizing the recycling of cooling water. This not only reduces production costs but also improves the environmental protection and sustainability of the entire mixing device. During the entire mixing process, the mixing component 2 and the reflux component 4 work together to continuously cool the mixing shaft 21 and the mixing plate 22, ensuring that the mixing operation is carried out at a suitable temperature.

[0022] The part where the condenser tube 25 is fixedly inserted into the stirring plate 22 is U-shaped. The stirring plate 22 has a row of round holes 221. The inner wall of the stirring shaft 21 is fixed with a heat-conducting and heat-absorbing aluminum ring plate 26. The aluminum ring plate 26 is fixedly inserted into and connected to the condenser tube 25.

[0023] Furthermore, the U-shaped design of the condenser tube 25 and the fixed connection of the stirring plate 22 greatly increases the contact area between them. The row of circular holes 221 on the stirring plate 22 not only assists in mixing and dispersing materials during the stirring process, allowing them to be more evenly distributed within the mixing tank 1, but also promotes relative flow between the materials and the stirring plate 22 to a certain extent, reducing resistance. The heat-conducting and heat-absorbing aluminum ring plate 26 fixed to the inner wall of the stirring shaft 21 further enhances the heat dissipation capacity of the entire stirring device. Aluminum, as an excellent thermal conductor, has high thermal conductivity and can quickly absorb the heat transferred from the stirring shaft 21. The fixed connection between the aluminum ring plate 26 and the condenser tube 25 allows the absorbed heat to be rapidly conducted to the condenser tube 25 and carried away by the flowing cooling water.

[0024] The reflux assembly 4 includes an annular groove 41 fixed to the top of the mixing tank 1. The annular groove 41 surrounds the mixing shaft 21 inside. The outer side of the annular groove 41 is higher than the inner side. A return water L-shaped pipe 43 is installed on the top of the condenser tube 25 relative to the other end of the connecting pipe joint 23. The return water L-shaped pipe 43 extends out of the mixing shaft 21, and the bottom outlet of the return water L-shaped pipe 43 is close to the bottom of the annular groove 41. A return liquid pipe 42 is connected to the cooling water tank 12 on the outer wall of the annular groove 41.

[0025] Through the design of the reflux assembly 4, during the stirring process, when the cooling water in the condenser tube 25 absorbs the heat transferred by the stirring shaft 21 and the stirring plate 22, the temperature rises and flows out from the other end of the top of the condenser tube 25 into the return water L-shaped pipe 43. The bottom outlet of the return water L-shaped pipe 43 is close to the bottom of the annular groove 41, so that the water flowing out of the return water L-shaped pipe 43 can fall into the annular groove 41 smoothly and accurately, avoiding hot water splashing or overflow, and ensuring effective collection of cooling water. Afterwards, the water collected in the annular groove 41 will flow smoothly back to the cooling water tank 12 through the return liquid pipe 42 to achieve recycling.

[0026] A rubber gasket 45 is bonded to the side wall of the inner ring of the annular groove 41. The rubber gasket slides with low resistance against the outer wall of the stirring shaft 21, which serves as a seal. An arc plate 44 is fixed to the vertical part of the return water L-shaped pipe 43. The two sides of the arc plate 44 are close to but do not contact the inner wall of the annular groove 41.

[0027] Furthermore, the sealing effect of the rubber gasket 45 effectively prevents the cooling water from leaking out from the gap between the annular groove 41 and the stirring shaft 21 during the reflux process, while the arc plate 44 can play a certain protective role against the splashing caused by the cooling water dripping. It should be noted that the cooling water tank 12 is an existing technology, which has its own cooling equipment, and will not be described in detail here.

[0028] The L-shaped frame 11 is connected to the stirring shaft 21 by a drive assembly 3, which includes a motor 31 fixed on one side of the L-shaped frame 11. The bottom output shaft of the motor 31 is connected to a pulley 32. The pulley 32 and the stirring shaft 21 are wound together with a belt body 33. The belt body 33 passes through the corresponding opening of the L-shaped frame 11. The outer wall of the stirring shaft 21 is provided with limiting ring plates at the upper and lower ends of the winding position of the belt body 33.

[0029] With the design of the drive component 3, when the rotation stirring is performed, the motor 31 starts and its bottom output shaft begins to rotate at a constant speed, driving the pulley 32 connected to it to rotate synchronously. Since the belt body 33 is tightly and securely wound around the pulley 32 and the stirring shaft 21, and the winding position of the belt body 33 on the stirring shaft 21 is limited by the limiting ring plates at its upper and lower ends to prevent slippage, when the pulley 32 rotates, the powerful rotational force is smoothly and efficiently transmitted to the stirring shaft 21 through the belt body 33 for stirring, which is very convenient.
