Description

Technical Field

[0001] This utility model relates to the field of dust control technology in construction, specifically a dual-shaft stirring and homogenizing device for cosmetic production. Background Technology

[0002] In the cosmetics manufacturing industry, the texture, stability, and skin feel of a product are key factors that determine its quality. As a core step in the cosmetics manufacturing process, the mixing and homogenization process directly affects the uniformity of raw material mixing, the dispersion effect of active ingredients, and the physicochemical properties of the final product. In the cosmetics manufacturing process, mixing and homogenization devices have been widely used for the mixing, emulsification, and homogenization of raw materials.

[0003] Most existing mixing and homogenizing devices adopt a single-shaft mixing structure. However, cosmetic raw materials often have large differences in component density and high viscosity. When homogenizing them, it is easy to have problems with insufficient mixing in some areas and insufficient mixing at the edges, resulting in low homogeneity of the finished product, which affects the skin feel and stability of the cosmetic. Furthermore, the mixing components cannot fit against the vessel wall, which can cause material to adhere to the inner wall of the mixing vessel. This not only wastes raw materials, but also may cause oxidation and deterioration of the residual material over a long period of time, contaminating subsequent batches of products. At the same time, the discharge structure mostly uses simple valve control. However, cosmetic finished products have high viscosity, and leakage will lead to product loss. Blockage will require shutdown for cleaning, which will affect production efficiency. Moreover, some equipment is only designed with a single discharge port, which cannot meet the needs of multiple batches or continuous discharge. Utility Model Content

[0004] The purpose of this invention is to provide a dual-shaft mixing and homogenizing device for cosmetic production, which has the advantages of uniform mixing and high discharge accuracy, and solves the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-shaft mixing and homogenizing device for cosmetic production includes a mixing vessel with two discharge ports at the bottom. The mixing vessel contains a mixing assembly for homogenizing cosmetic products, and a discharge assembly for discharging cosmetic products. The mixing assembly includes mixing shafts rotatably connected to the interior of the mixing vessel. Two sets of mixing shafts are provided, with mixing plates symmetrically arranged on the outer sides of the mixing shafts and arranged in a cross configuration. A transmission housing is installed on the left side of the mixing vessel, and one end of each set of mixing shafts is installed within the transmission housing.

[0007] Preferably, a servo motor is installed at the top of the transmission box, and the output end of the servo motor is connected to the transmission box. Rubber scrapers are installed on the back side of the stirring plate.

[0008] It is worth noting that the servo motor can precisely control the operating speed and direction of the transmission box, ensuring that the stirring shaft drives the stirring plate to achieve stable and controllable stirring action, thereby improving the stirring and homogenization effect. The rubber scraper on the back side of the stirring plate can scrape off residual materials from the inner wall of the mixing vessel during the stirring process, which reduces raw material waste and prevents residual materials from adhering for a long time and causing deterioration. At the same time, it keeps the inner wall of the mixing vessel clean, which is convenient for subsequent cleaning, maintenance and next use.

[0009] Preferably, a connecting rod is connected between the stirring plate and the stirring shaft, and the connecting rod is symmetrically arranged on the stirring plate, with a flow divider groove inside the connecting rod.

[0010] It is worth noting that the centrally symmetrically arranged connecting rods make the connection between the mixing plate and the mixing shaft more stable, disperse the force generated during the mixing process, avoid excessive local stress that could damage the components, and extend the service life of the device; the flow divider inside the connecting rods can guide the material during mixing, break up the material agglomeration, and allow the material to contact the mixing plate more fully, further improving the uniformity of the mixing and ensuring the quality of the cosmetic raw material mixture.

[0011] Preferably, a support frame is provided on one side of the mixing vessel, and the mixing shaft is mounted on the support frame via a bearing bracket. A bracket is installed on the other side of the mixing vessel, and the transmission box is mounted on the bracket.

[0012] It is worth noting that: the support frame supports the stirring shaft through the bearing frame, which can reduce the shaking of the stirring shaft when it rotates at high speed, ensure its operational stability, and avoid affecting the stirring effect or causing wear of parts due to shaft shaking; the bracket provides a stable mounting base for the transmission box, so that the transmission box and the stirring shaft maintain a precise transmission fit relationship, ensuring efficient and stable power transmission. At the same time, support structures are set on both sides to balance the force on the entire stirring assembly and improve the overall structural stability of the device.

[0013] Preferably, the discharge assembly includes a telescopic cylinder, which is installed on the right side of the mixing vessel, and two sets of telescopic cylinders are provided. The telescopic cylinders are located below the support, and the output end of the telescopic cylinder is connected to a connecting rod, which is located at the bottom of the mixing vessel.

[0014] It is worth noting that the synchronous drive of the connecting rod by the two sets of telescopic cylinders provides sufficient and stable power for the discharge control, avoiding the problems of insufficient power or movement jamming that may occur with single cylinder drive; the connecting rod is set at the bottom of the mixing tank, which can directly drive the subsequent discharge components to move precisely, shorten the power transmission path, reduce power loss, and at the same time make it easy for operators to intuitively observe the operating status of the discharge components, reducing maintenance difficulty.

[0015] Preferably, a sliding ring is slidably connected to the outer side of the connecting rod, a support plate is installed on one side of the sliding ring, and an mounting plate is installed on the top of the support plate.

[0016] It is worth noting that the sliding engagement between the sliding ring and the connecting rod makes the movement of the support plate and the mounting plate smoother, reduces frictional resistance between components, reduces mechanical wear, and extends the service life of components. By connecting the sliding ring and the mounting plate through the support plate, the position of the mounting plate can be flexibly adjusted, making it easy to adapt to different specifications of baffles according to actual material discharge requirements, thereby improving the versatility and adaptability of the device.

[0017] Preferably, the top of the mounting plate is provided with a baffle, and the baffle is located inside the discharge port of the mixing vessel.

[0018] It is worth noting that the baffle is directly installed inside the discharge port of the mixing vessel, which can accurately control the opening and closing of the discharge port, effectively preventing material leakage during the mixing process, ensuring a sealed environment inside the mixing vessel, and ensuring the homogenization effect of the mixing. At the same time, the baffle is firmly connected to the mounting plate and responds quickly under the drive of the telescopic cylinder, which can accurately control the discharge speed and discharge volume, meeting the quantitative output requirements of materials in the cosmetic production process.

[0019] Preferably, a sealing plate is provided at the middle position of the top of the baffle, and fixing rings are installed on both the left and right sides of the top of the mixing vessel, with adjacent fixing rings connected by bolts. A feed inlet is provided at the middle position of the top of the mixing vessel.

[0020] It is worth noting that: the sealing plate at the top of the baffle can further enhance the sealing performance of the discharge port, especially when there is pressure inside the mixing tank or the material is in a viscous state, it can effectively prevent the material from leaking from the gap between the baffle and the discharge port, thus improving the sealing performance of the device; the fixing rings on the left and right sides of the top of the mixing tank are connected by bolts, which facilitates the disassembly and assembly of the mixing tank, and makes it convenient to maintain, replace or clean the internal components of the tank, reducing equipment maintenance costs; the feed inlet in the middle of the top is reasonably positioned, which facilitates the concentrated input of raw materials, reduces the spillage and waste of raw materials during the feeding process, and the matching position of the feed inlet with the mixing components allows the raw materials to enter the mixing area quickly, improving the mixing efficiency.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] When the stirring shaft of this invention rotates, it drives the stirring plates, which are symmetrically arranged and cross-shaped on the outer side, to rotate together. The stirring plates mix the cosmetic raw materials in the mixing vessel. At the same time, the rubber scraper on the opposite side of the stirring plate slides against the inner wall of the mixing vessel, scraping off the raw materials attached to the vessel wall. Through the dual-shaft stirring shaft, the raw materials can be acted on from both sides of the vessel body simultaneously, effectively avoiding the mixing blind zone when stirring with a single shaft. At the same time, the stirring force of the two sets of stirring shafts is more balanced, avoiding the stratification or incomplete mixing of the raw materials due to a single direction of movement, and ultimately improving the uniformity of the texture of the finished product.

Detailed Implementation

[0031] 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.

[0032] To address the problems of uneven mixing and poor material discharge in existing technologies, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-6 ;

[0033] A dual-shaft mixing and homogenizing device for cosmetic production includes a mixing vessel 1 with two discharge ports at its bottom. The mixing vessel 1 contains a mixing assembly for homogenizing cosmetic products and a discharge assembly for discharging cosmetic products. The mixing assembly includes a mixing shaft 301 rotatably connected to the interior of the mixing vessel 1. Two sets of mixing shafts 301 are provided. Mixing plates 302 are symmetrically arranged at the outer center of the mixing shafts 301 and are arranged in a cross configuration. A transmission housing 303 is installed on the left side of the mixing vessel 1, and one end of each set of mixing shafts 301 is installed within the transmission housing 303.

[0034] A servo motor 304 is mounted on the top of the transmission housing 303, and the output end of the servo motor 304 is connected to the transmission housing 303. Rubber scrapers 305 are mounted on the opposite side of the stirring plate 302. A connecting rod 306 connects the stirring plate 302 and the stirring shaft 301, and the connecting rod 306 is symmetrically arranged on the stirring plate 302. A flow divider 307 is opened inside the connecting rod 306. A support frame 308 is provided on one side of the stirring vessel 1, and the stirring shaft 301 is mounted on the support frame 308 through a bearing bracket. On the other side of the mixing vessel 1, a bracket 309 is installed, and a transmission box 303 is mounted on the bracket 309. This prevents uneven mixing of raw materials due to unstable power. At the same time, the transmission box 303 can effectively transmit and buffer the motor power, reduce power loss, and ensure the continuous and stable operation of the mixing shaft 301. The rubber scraper 305 installed on the opposite side of the mixing plate 302 can closely follow the inner wall of the mixing vessel 1 and move synchronously during the mixing process. It can scrape off the cosmetic raw materials adhering to the vessel wall in real time, preventing the raw materials from being damaged by prolonged contact with the wall. The solidification and deterioration of the adhering material reduces raw material waste and prevents residual raw materials from contaminating subsequent batches of products, meeting the stringent hygiene requirements of cosmetic production. The stirring plate 302 and the stirring shaft 301 are connected by a centrally symmetrically arranged connecting rod 306. The symmetrical structure ensures that the stirring plate 302 is subjected to uniform force during operation, avoiding the displacement or vibration of the stirring shaft 301 due to excessive force on one side, thereby ensuring consistent force on the raw materials within the stirring range and improving the uniformity of raw material mixing. At the same time, the flow divider 307 opened inside the connecting rod 306 can guide the flow of raw materials during stirring, breaking the phenomenon of raw material agglomeration and further enhancing the homogenization effect, which is especially suitable for mixing powder and liquid raw materials in cosmetics. The support frame 308 on one side of the mixing vessel 1 supports the stirring shaft 301 through the bearing frame, which can reduce the shaking of the stirring shaft 301 during high-speed operation and reduce shaft wear. The bracket 309 on the other side fixes the transmission box 303 to prevent the connection of components from loosening due to equipment vibration, thereby improving the overall structural stability of the device and extending the overall service life of the equipment.

[0035] The discharge assembly includes a telescopic cylinder 401, which is installed on the right side of the mixing vessel 1. Two sets of telescopic cylinders 401 are provided, and each is positioned below the bracket 309. The output end of the telescopic cylinder 401 is connected to a connecting rod 402, which is located at the bottom of the mixing vessel 1. A sliding ring 403 is slidably connected to the outer side of the connecting rod 402. A support plate 404 is installed on one side of the sliding ring 403, and an mounting plate 405 is installed on the top of the support plate 404. A baffle 406 is provided on the top of the mounting plate 405. The device is placed inside the discharge port of the mixing vessel 1. A sealing plate 407 is installed at the middle position of the top of the baffle 406. Fixing rings 408 are installed on both the left and right sides of the top of the mixing vessel 1, and adjacent fixing rings 408 are connected by bolts. A feed port 2 is located at the middle position of the top of the mixing vessel 1. The device is equipped with two sets of telescopic cylinders 401. Through the connecting rods 402 and sliding rings 403 connected to their output ends, the baffle 406 is moved, which can precisely adjust the opening and closing degree of the discharge port of the mixing vessel 1. This facilitates the control of the discharge speed and quantity of cosmetic raw materials and meets the requirements of different production stages. The discharge requirements are met; simultaneously, the sealing plate 407 at the top center of the baffle 406 can fit tightly when the discharge port is closed, effectively preventing raw material leakage or the entry of external impurities during the stirring process, ensuring the purity of cosmetic raw materials and the cleanliness of the production environment; the telescopic cylinder 401 is installed on the right side of the mixing vessel 1 and located below the bracket 309, which can support and fix the telescopic cylinder 401, reducing its shaking during operation; the fixing rings 408 on the left and right sides of the top of the mixing vessel 1 are connected by bolts, further enhancing the overall structural stability of the mixing vessel 1. To prevent components from loosening due to vibration during biaxial mixing and homogenization, ensuring long-term stable operation of the equipment and reducing the production failure rate, a feed inlet 2 is set at the top center of the mixing vessel 1. This position allows operators or automated feeding equipment to directly put various raw materials required for cosmetics into the vessel without additional adjustment of the feeding angle or path, simplifying the feeding operation process. At the same time, the design of feeding in the middle allows the raw materials to be more evenly distributed in the mixing vessel 1, laying a good foundation for the subsequent biaxial mixing and homogenization process, and helping to improve the mixing uniformity of cosmetic raw materials and product quality.

[0036] Working principle: The cosmetic raw materials to be homogenized are slowly added into the mixing vessel 1 through the feed inlet 2 according to the formula ratio. After the raw materials are added, the feed inlet 2 is closed to prevent splashing during the mixing process. The servo motor 304 is started, and the power is transmitted to the transmission box 303. Through the transmission gear inside the transmission box 303, the two sets of stirring shafts 301 are driven to rotate synchronously inside the mixing vessel 1. When the stirring shafts 301 rotate, they drive the stirring plates 302, which are symmetrically arranged and cross each other on the outer side, to rotate together. The stirring plates 302 mix the cosmetic raw materials in the mixing vessel 1. At the same time, the rubber scraper 305 on the opposite side of the stirring plate 302 slides against the inner wall of the mixing vessel 1 to scrape off the raw materials adhering to the vessel wall. The connecting rod 306 moves with the stirring plates 301 and 302. 2. Rotation allows the raw materials to flow through the diversion groove 307 inside the connecting rod 306, further improving the uniformity of the raw material mixing and achieving homogenization of the cosmetic raw materials. After stirring, the piston rod of the telescopic cylinder 401 is extended, driving the connecting rod 402 to move horizontally at the bottom of the mixing vessel 1. The sliding ring 403 on the outside of the connecting rod 402 slides synchronously with the connecting rod 402, thereby driving the mounting plate 405 to move through the support plate 404. The baffle 406 at the top of the mounting plate 405 moves out of the discharge port of the mixing vessel 1, and the sealing plate 407 separates from the inner wall of the discharge port, opening the discharge port. The cosmetic raw materials that have been homogenized in the mixing vessel 1 are discharged through two discharge ports. The staff places a collection container below the discharge port to collect the finished raw materials.
