Abstract
Description
Technical Field
[0001] This utility model relates to an emulsifying mixer, and more particularly to an emulsifying mixer for toothpaste viscosity. Background Technology
[0002] The main components of regular toothpaste include abrasives, binders, detergents, humectants, preservatives, flavorings, and water. It contains both powdery and liquid components, requiring emulsification during production. The industry commonly uses single-screw or planetary mixing systems to mix the toothpaste emulsion.
[0003] Single-screw agitators typically employ either a frame-type or a three-bladed swept-back design. Frame-type agitators concentrate shear force at the edges, potentially causing excessive localized disruption of the toothpaste's three-dimensional structure and resulting in inconsistent, locally thinned paste. Three-bladed swept-back designs primarily involve radial shear, which can easily trap air bubbles in the paste, affecting subsequent vacuum degassing. Furthermore, the radial flow diffusion of three-bladed swept-back designs can create a residual layer on the can wall, making it difficult to effectively agitate the material, leading to waste and the risk of contamination from repeated mixing.
[0004] Planetary mixing systems, most commonly used in the toothpaste manufacturing industry, are multi-screw mixers. For example, a novel toothpaste production mixing tank (publication number CN216458128U) includes a tank body. Inside the tank body, near the top, a drive assembly is located. Fixed plates are fixedly installed on the inner walls of both sides of the tank body. Annular discs are bolted to the bottom surfaces of both fixed plates. Annular slide rails are fixedly installed on the bottom surfaces of the annular discs. Two sliders are slidably connected to the bottom surfaces of the annular slide rails. Annular plates are fixedly installed on the bottom surfaces of the two sliders. Two mixing components are located at the bottom of the annular plates. This design uses a motor to drive a rotating rod, which in turn drives a gear to rotate, causing two mixing blades to simultaneously stir inside the tank. However, this method has a single mixing method and generally poor emulsification. The energy transmission method suffers from high losses and low transmission efficiency; insufficient torque forces an increase in rotational speed. The mixing blades use a single spiral design, resulting in a large dead zone and making it easier to form a residue layer compared to a three-bladed swept-back design, which is typically thicker.

[0005] To address the shortcomings of the aforementioned technologies, this invention provides a toothpaste viscosity emulsifying mixer.
[0006] To solve the above technical problems, the technical solution adopted by this utility model is: a toothpaste viscosity emulsification mixer, including a tank with an inlet pipe, an outlet pipe and an inner cavity, a main motor is set at the top center of the tank and drives a ribbon stirring paddle, a first auxiliary motor is set on one side of the main motor to drive a first wall scraping stirring paddle located next to the ribbon stirring paddle, and a second auxiliary motor is set on the bottom surface of the tank to drive a second wall scraping stirring paddle.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0025] like Figure 1-5 As shown in the figure, this embodiment of the toothpaste viscosity emulsifying mixer includes a tank 1 with an inlet pipe 2, an outlet pipe 5, and an inner cavity. The outlet pipe 5 is located at the center of the bottom surface of the tank 1. In this embodiment, the emulsification mixing method of this application is a multi-mixing method, specifically:
[0026] like Figure 1As shown, a main motor 6 is installed at the center of the top surface of the tank 1, driving a spiral stirring paddle 9. A first auxiliary motor 7 is installed on one side of the main motor 6, driving a first wall-scraping stirring paddle 10 located next to the spiral stirring paddle 9. A second auxiliary motor 8 is installed on the bottom surface of the tank 1, driving a second wall-scraping stirring paddle 11. The first auxiliary motor 7 and the second auxiliary motor 8 are offset and located on the same cross-sectional plane. It is understood that each of the multiple stirring units in this embodiment has its own driving unit. Compared with the traditional single stirring form, the stirring effect is better. Compared with the traditional planetary stirring system, the energy transfer efficiency of stirring is faster. Moreover, the speed and direction of rotation can be controlled separately according to actual production needs to prevent the paste from being too thin or the stirring from being uneven. It should be noted that in this embodiment, the spiral stirring paddle 9 provides the main shear force for stirring the toothpaste raw materials, while the first wall-scraping stirring paddle 10 and the second wall-scraping stirring paddle 11 are auxiliary stirring structures to improve the stirring uniformity and paste consistency, and reduce stirring dead zones and tank wall residue.
[0027] Preferably, the top surface of the tank 1 is also provided with an auxiliary feeding pipe 3 that communicates with its inner cavity. The auxiliary feeding pipe 3 is mainly used for adding food additives, including flavorings and sweeteners, and is adapted to toothpaste that requires the addition of flavorings and sweeteners for production. In addition, one side of the auxiliary feeding pipe 3 is equipped with a viewing window 4 that is sealed and connected to the tank 1. The viewing window 4 is used to observe the stirring of the paste, and it is convenient for the operator to adjust the operating parameters of the main motor 6, the first auxiliary motor 7, and the second auxiliary motor 8 through an external controller to improve the quality of the finished toothpaste paste.
[0028] like Figure 2-3 As shown, the ribbon agitator 9 is a double-ribbon type, with each ribbon spiraling from top to bottom and the upper and lower connection points located on the free end of the support plate, thereby increasing the agitation range of the ribbon agitator 9. The connection between the ribbon agitator 9 and the main motor 6 can be achieved through a coupling or by equipping the main motor 6 with a reducer, which can be customized according to actual production needs. This is existing technology, and its purpose is to enhance the connection stability between the main motor 6 and the ribbon agitator 9 to ensure production capacity.
[0029] refer to Figure 1-2 As shown, the axis of rotation of the three components—the ribbon agitator 9, the first wall-scraping agitator 10, and the second wall-scraping agitator 11—is connected on the same cross-sectional plane. In other words, the axis of rotation of the three components is a straight line, covering the largest possible mixing range to eliminate dead zones. Furthermore, the motion trajectories of the three components within the inner cavity of the tank 1 are complementary. The vortex and shear flow field of the ribbon agitator 9, together with the first wall-scraping agitator 10 and the second wall-scraping agitator 11 on its left and right sides, constitute a mixing cycle, improving the uniformity of mixing. This layout also facilitates observation by the operator through the viewing window 4.
[0030] In this embodiment, as Figure 2 As shown, the first wall-scraping agitator 10 and the second wall-scraping agitator 11 have the same structure and both include a rotating shaft 12 and several support arms 14 located on the outer periphery of the rotating shaft 12. The support arms 14 are provided with a central scraper 17 and a top / bottom scraper 18.
[0031] Preferably, the rotating shaft 12 extends vertically, with a gap between the free end of the rotating shaft 12 of the first wall-scraping agitator 10 and the bottom surface of the tank 1, and a gap between the free end of the rotating shaft 12 of the second wall-scraping agitator 11 and the top surface of the tank 1. Figure 2 As shown above, the first auxiliary motor 7 and the second auxiliary motor 8 are staggered, which clarifies that the driving ends of the first wall-scraping stirring paddle 10 and the second wall-scraping stirring paddle 11 in this embodiment are located at different positions. The first wall-scraping stirring paddle 10 is driven by the upper first auxiliary motor 7, and the second wall-scraping stirring paddle 11 is driven by the lower second auxiliary motor 8. Therefore, the material flow around each of them is different. Combined with the vortex of the ribbon stirring paddle 9, a three-dimensional material flow is formed from one side to the other, which further stirs the paste without excessively breaking the internal structure of the toothpaste paste like in traditional planetary stirring systems. This significantly improves the viscosity during the mixing stage, thereby improving the emulsification and stirring efficiency.
[0032] like Figure 4-5 As shown, several auxiliary connecting plates 13 are welded onto the rotating shaft 12, arranged in a staggered manner. The auxiliary connecting plates 13 are in the shape of a cut semi-circular flange, so that they can fit against the outer peripheral wall of the rotating shaft 12. Then, each auxiliary connecting plate 13 is equipped with a support arm 14 perpendicular to the rotating shaft 12. The auxiliary connecting plates 13 and support arms 14 are connected by bolts 15. It can be understood that the joint between the support arm 14 and the rotating shaft 12 is also shaped and adapted. The auxiliary connecting plates 13 are used to connect the support arms 14, so that the two form a stable connection relationship. In actual production, if the structure of the support arm 14 does not need to be changed in subsequent production, the joint between the support arm 14 and the rotating shaft 12 can be welded after the auxiliary connecting plates 13 and the support arm 14 are connected by bolts 15.
[0033] The free end of the support arm 14 is machined with inclined connecting blocks 16, each connecting block 16 is equipped with a scraper, so the scraper is also inclined. In this embodiment, the scraper includes a central scraper 17 and a top / bottom scraper 18, which are made of rubber to prevent scratching the tank 1. In this embodiment, the central scraper 17 is used to scrape off the residue on the tank wall, that is, the inner wall of the tank 1, and the top / bottom scraper 18 is used to scrape off the paste residue on the tank wall. The paste residue is the paste residue on the top / bottom scraper 18 and the inner top surface and / or inner bottom surface of the tank 1. It should be noted that in actual production, the paste residue on the inner top surface and inner bottom surface of the tank 1 is not much and is not stubborn and difficult to remove.
[0034] Preferably, the support arms 14 located at both ends of the rotating shaft 12 are bolted to the top / bottom scraper 18 via connecting blocks 16. The portions of the top / bottom scraper 18 facing the inner top and / or inner bottom surfaces of the tank 1 form scraper blades 19, which are used to improve scraping efficiency; such as Figure 2 As shown, the first wall-scraping agitator 10, with its top / bottom scraper 18 near the first auxiliary motor 7, can scrape off some of the paste residue on the top surface of the tank 1, and the second wall-scraping agitator 11, with its top / bottom scraper 18 near the second auxiliary motor 8, can scrape off some of the paste residue on the bottom surface of the tank 1.
[0035] Preferably, the support arms 14 located at the two ends of the rotating shaft 12 are respectively bolted to the central scraper 17 via connecting blocks 16. The back of the central scraper 17 is machined with a limiting groove 20 that matches the connecting block 16. The setting of the limiting groove 20 makes the positioning connection between the central scraper 17 and the connecting block 16 more secure, preventing the central scraper 17 from being improperly displaced or tilted after long-term use.
[0036] Several central scrapers 17 are arranged in pairs, with the two central scrapers 17 in each pair having opposite inclination directions, and adjacent central scrapers 17 in each pair having the same inclination angle, and as shown in the figure. Figure 5 As shown, there is also a phase difference between the two central scrapers 17 in the group, so the central scrapers 17 on the entire first wall scraping agitator 10 or the second wall scraping agitator 11 form a gradient difference, which has the ability to perform time-sharing action when rotating and scraping. When rotating, the central scrapers 17 contact the tank wall of the tank 1 in sequence, forming a stepped scraping trajectory, which is conducive to cooperating with the vortex of the ribbon agitator 9 and reducing crossflow.
[0037] This application discloses a toothpaste viscosity emulsifying mixer. Through multiple mixing modes, the material flow design is optimized, enhancing the efficiency of mixing kinetic energy transfer. This significantly improves the mixing efficiency and uniformity of toothpaste production, reduces material residue and contamination risks, optimizes the finished quality of the toothpaste paste, and facilitates observation and adjustment during the production process. Specifically, a multi-mode mixing system is formed by a ribbon agitator, a first wall-scraping agitator, and a second wall-scraping agitator, effectively improving mixing efficiency and uniformity, covering the largest mixing range, eliminating dead zones, and allowing the paste to be more thoroughly mixed within the container. Furthermore, the first and second wall-scraping agitators form a mixing cycle, improving mixing uniformity while reducing residue on the container walls, thereby reducing material waste and the risk of contamination from multiple mixing processes.
[0038] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
