Description

Technical Field

[0001] This utility model belongs to the technical field of oral product manufacturing equipment, specifically relating to a stirring device for mixing high molecular weight plasticizers in toothpaste. Background Technology

[0002] In toothpaste manufacturing, polymeric shaping agents are one of the key functional additives. Their role is to regulate the rheological properties of the toothpaste, such as extrudability and thixotropy, improve the structural stability of the toothpaste, and enhance the sensory experience during use. Since polymeric shaping agents are typically high-viscosity polymers, such as sodium carboxymethyl cellulose and hydroxyethyl cellulose, their uniform mixing with the toothpaste base, containing abrasives, humectants, surfactants, and other components directly affects product quality.

[0003] Currently, traditional toothpaste mixing devices mostly employ single-shaft paddle or frame mixing structures, which have the following limitations when mixing polymer plasticizers: Traditional devices typically have a 5-10mm gap between the mixing paddle and the inner wall of the tank, and the scraping structure is usually a fixed, rigid scraper. When high-viscosity polymer materials adhere to the tank wall, the scraper is difficult to completely remove them, resulting in a gel layer with a thickness of 0.5-2mm remaining on the inner wall. This residual material gradually solidifies after the equipment is shut down, not only increasing the difficulty of subsequent cleaning, requiring repeated manual wiping with solvents, but also mixing into the new batch of materials in the next production run, creating cross-contamination of "old material contaminating new material." This directly leads to fluctuations in key indicators such as viscosity and thixotropy between different batches of products, seriously affecting quality stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, a stirring device for mixing high molecular weight plasticizers in toothpaste is provided to solve the problems of uneven mixing inside the container and residual contamination affecting product quality.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A stirring device for mixing toothpaste polymer plasticizers, comprising: Tank body; A drive motor is installed on the top of the tank. A stirring assembly is disposed in the tank, and the stirring assembly includes: The stirring shaft is connected to the output end of the drive motor; A stirring frame is connected to the stirring shaft; Several scraper assemblies are rotatably connected to the outside of the stirring frame. The scraper assemblies are attached to the inner wall of the tank, and the scraper assemblies on both sides are arranged alternately.

[0006] Compared with existing technologies, the above technical solutions have the following beneficial effects: The system utilizes a drive motor to rotate both the stirring shaft and the stirring frame simultaneously. The stirring shaft stirs the material in the center of the tank, while the stirring frame stirs the material around the outer perimeter of the tank. This ensures thorough mixing of the material inside the tank, guaranteeing more uniform mixing. Multiple scraper assemblies are installed on the outer side of the stirring frame, adhering to the inner wall of the tank. As the stirring frame rotates, the scrapers maintain constant contact with the inside of the tank, removing material adhering to the inner wall. Furthermore, the upper limits of the scraper assemblies on both sides are staggered, ensuring complete coverage of the inner wall during scraping and preventing blind spots.

[0007] Based on the above technical solution, the embodiments of this application can be further improved as follows: In one embodiment, the scraper assembly includes: A connecting bracket is rotatably connected to the outside of the stirring frame, and a stepped groove is provided on the outside of the connecting bracket; A scraper, one side of which is fitted into the stepped groove, and the other side extends out of the stepped groove and fits against the inner wall of the tank; The pad rests against the scraper on the side away from the stepped groove. The fastener passes through the stepped groove and is securely connected to the scraper.

[0008] The scraper is secured by the stepped groove on the connecting bracket, and then the pad plate is used to restrict the scraper on three sides, so that the scraper is firmly and stably installed on the connecting bracket.

[0009] In one embodiment, a rotating shaft is provided on the connecting bracket, and pin seats are rotatably connected to both ends of the rotating shaft. The pin seats are fixed to the outside of the stirring frame. A first elastic element is sleeved on the rotating shaft. One end of the first elastic element abuts against the stirring frame, and the other end abuts against the connecting bracket, which is used to push the connecting bracket to rotate, thereby causing the scraper on it to abut against the inner wall of the tank.

[0010] The first elastic element sleeved on the rotating shaft can push the connecting bracket toward the inner wall of the tank, so that the scraper can be in real time attached to the inner wall of the tank.

[0011] In one embodiment, the telescopic traction component on the connecting bracket has one end connected to the connecting bracket and the other end connected to the stirring frame, which is used to limit the rotation angle of the connecting bracket.

[0012] By setting up a telescopic traction component, it is possible to avoid excessive elasticity of the first elastic element, which would accelerate the wear of the scraper. At the same time, it can ensure that after the scraper wears excessively, the connecting bracket will not rotate excessively due to the elasticity of the first elastic element.

[0013] In one embodiment, the telescopic pulling assembly includes a second elastic element, one end of which is connected to a fixed seat disposed on the stirring frame, and the other end is screwed and fastened to the fastener by a nut.

[0014] In one embodiment, the scraper surface is provided with an anti-adhesion layer.

[0015] By applying a low surface energy anti-adhesion material to the scraper, the adhesion of viscous materials to the scraper surface can be reduced, thereby improving scraping efficiency.

[0016] In one embodiment, a first stirring blade is spaced apart on the stirring shaft, and a second stirring blade is spaced apart inside the stirring frame, with the first stirring blade and the second stirring blade arranged at intervals.

[0017] In one embodiment, the tank body is covered with an insulation cylinder, and a coil is provided in the insulation cylinder to surround the tank body. An inlet pipe and an outlet pipe extending out of the insulation cylinder are respectively provided at both ends of the coil.

[0018] During the mixing process, the internal temperature of the tank is maintained within a suitable range by introducing refrigerant or heat through coils, so as to avoid problems such as excessive viscosity or structural damage to polymer materials due to excessively high or low temperatures, which would affect performance.

[0019] In one embodiment, a homogenizing and stirring device is provided at the bottom of the tank, and the stirring head of the homogenizing and stirring device extends into the bottom of the tank.

[0020] In one embodiment, a plurality of support leg assemblies are arranged circumferentially at intervals at the bottom of the tank body. Each support leg assembly includes a first support leg, a weighing module disposed at the bottom of the first support leg, and a second support leg disposed at the bottom of the weighing module.

[0021] By installing a weighing module in the support leg assembly, the weight of each batch of material added to the tank can be detected, and the amount of material added can be fed back to control the amount of material added in batches, so as to avoid adding too much material at once, which would lead to excessively high local concentration and affect the uniformity of mixing.

[0030] Example like Figure 1-2 As shown, the present invention provides a stirring device for mixing high molecular weight plasticizers in toothpaste, which includes: a tank 1, a drive motor 2 and a stirring assembly 7.

[0031] The tank body 1 is provided with a feed inlet 5 at the top and a discharge outlet 6 at the bottom. The tank body 1 is also provided with a manhole 4 at the top, and a sight glass is provided on the manhole 4 for observing the working status of the scraper 7033.

[0032] The drive motor 2 is mounted on the top of the tank 1 via the motor bracket 3. The stirring assembly 7 is disposed in the tank 1. The stirring assembly 7 extends from the top of the tank 1 and is connected to the drive motor 2 for transmission. The drive motor 2 drives the stirring assembly 7 in the tank 1 to rotate as a whole. The stirring assembly 7 includes: a stirring shaft 701, a stirring frame 702, and several scraper assemblies 703.

[0033] A stirring shaft 701 is located at the center of the tank 1 and is connected to the output end of the drive motor 2. A stirring frame 702 is connected to the stirring shaft 701. The outer contour of the stirring frame 702 basically fits the contour of the inner wall of the tank 1 and maintains a certain gap with the inner wall of the tank 1. The scraper assembly 703 is rotatably connected to the outside of the stirring frame 702. The scraper assembly 703 is attached to the inner wall of the tank 1. The scraper assemblies 703 on both sides are arranged alternately, and the scraper assemblies 703 on adjacent sides have a certain overlap in the scraping range, so that after the stirring frame 702 rotates one revolution, there is no scraping blind zone between two adjacent scraper assemblies 703.

[0034] The drive motor 2 drives the stirring shaft 701 and the stirring frame 702 to rotate simultaneously. The stirring shaft 701 stirs the material in the center of the tank 1, and the stirring frame 702 stirs the material on the outer periphery of the tank 1. This can fully stir the material inside the tank 1 and ensure that the material is stirred more evenly. At the same time, multiple scraper assemblies 703 are set on the outside of the stirring frame 702. The scraper assemblies 703 are attached to the inner wall of the tank 1. When the stirring frame 702 rotates, it can drive the scrapers 7033 to keep in constant contact with the inside of the tank 1 to scrape off the material adhering to the inner wall of the tank 1. At the same time, the upper limits of the scraper assemblies 703 on both sides are staggered, which can achieve full coverage of the inner wall surface of the tank 1 during scraping and avoid the creation of scraping blind spots.

[0035] Among them, such as Figure 2 As shown, the scraper assembly 703 includes: a connecting bracket 7031, a scraper 7033, and a pad 7034.

[0036] One side of the connecting bracket 7031 is rotatably connected to the outside of the stirring frame 702. The outer side of the connecting bracket 7031 is provided with a stepped groove 7032, and this side extends out of the outside of the stirring frame 702 without contacting the inner wall of the outer tank 1. One side of the scraper 7033 is fitted into the stepped groove 7032, and the other side extends out of the stepped groove 7032 and is attached to the inner wall of the tank 1. The stepped groove 7032 can fix the side and side edge of the scraper 7033. The pad 7034 abuts against the scraper 7033 on the side away from the stepped groove 7032. The scraper 7033 is clamped by the pad 7034 and the stepped groove 7032. Then, the fastener 7035 passes through the stepped groove 7032 and is fastened to the scraper 7033. The fastener 7035 can be bolts, nuts or the like.

[0037] The scraper 7033 is secured by the stepped groove 7032 on the connecting bracket 7031, and the scraper 7033 is further secured by the pad 7034 on three sides, so that the scraper 7033 is firmly and stably installed on the connecting bracket 7031.

[0038] Specifically, a rotating shaft 7036 is provided on the connecting bracket 7031. The rotating shaft 7036 is located on the side of the connecting bracket 7031 away from the scraper 7033. Pin seats 7037 are rotatably connected to both ends of the rotating shaft 7036. The pin seats 7037 are fixed to the outside of the stirring frame 702, so that the connecting shaft 7036 and the stirring frame 702 are rotatably connected. At the same time, a first elastic element 7038 is sleeved on the rotating shaft 7036. One end of the first elastic element 7038 abuts against the stirring frame 702, and the other end abuts against the connecting bracket 7031. The first elastic element 7038 can be implemented by a torsion spring. The torsion spring is used to push the connecting bracket 7031 to rotate, causing the scraper 7033 on it to abut against the inner wall of the tank 1. The first elastic element 7038 sleeved on the rotating shaft 7036 can push the connecting bracket 7031 toward the inner wall of the tank 1, so that the scraper 7033 can be in real time against the inner wall of the tank 1.

[0039] To prevent the first elastic element 7038 from excessively rotating the connecting bracket 7031, a telescopic tensioning component 706 is provided on the connecting bracket 7031. One end of the component is connected to the connecting bracket 7031, and the other end is connected to the stirring frame 702. This component is used to limit the rotation angle of the connecting bracket 7031. By providing the telescopic tensioning component 706, it is possible to prevent the first elastic element 7038 from having excessive elastic force, which would accelerate the wear of the scraper 7033. At the same time, it is possible to ensure that after the scraper 7033 is worn excessively, the connecting bracket 7031 will not rotate excessively due to the elastic force of the first elastic element 7038.

[0040] Specifically, the telescopic traction assembly 706 includes a second elastic element 7061, which can be implemented as a tension spring. One end of the second elastic element 7061 is connected to a fixing seat 7062 disposed on the stirring frame 702. The fixing seat 7062 is fastened to the stirring frame 702 by screwing. The other end of the second elastic element 7061 is screwed to the fastener 7035 by a nut. Specifically, the other end of the second elastic element 7061 is connected to a blind hole nut 7063, which is screwed to the protruding screw of the fastener 7035.

[0041] In this embodiment, to improve the self-cleaning ability of the scraper 7033, an anti-adhesion layer is provided on the surface of the scraper 7033. Specifically, a coating such as polytetrafluoroethylene can be used. By setting a low surface energy anti-adhesion material on the scraper 7033, the adhesion of viscous materials to the surface of the scraper 7033 can be reduced, thereby improving the scraping efficiency.

[0042] In this embodiment, a first stirring blade 704 is spaced apart on the stirring shaft 701, and a second stirring blade 705 is spaced apart on the inner side of the stirring frame 702. The first stirring blade 704 and the second stirring blade 705 are arranged at intervals to improve the stirring effect between the stirring shaft 701 and the stirring frame 702.

[0043] The tank body 1 is covered by an insulation cylinder 8. The insulation cylinder 8 is provided with a coil 9 surrounding the tank body 1. The insulation cylinder 8 covers the entire outside of the coil 9. The coil 9 is provided with an inlet pipe 10 and an outlet pipe 11 extending out of the insulation cylinder 8 at both ends. The insulation cylinder 8 can protect the coil 9. During the stirring process, the internal temperature of the tank body 1 is maintained within a suitable range by introducing refrigerant or hot medium through the coil 9. Correspondingly, the tank body 1 is also equipped with several temperature sensors. The sensing end of the temperature sensor extends into the inside of the tank body 1 to avoid problems such as excessive viscosity or structural damage to the polymer material due to excessively high or low temperatures, which would affect its performance.

[0044] A homogenizing and stirring device 12 is provided at the bottom of the tank body 1. The homogenizing and stirring device 12 is located near the discharge port 6 at the bottom of the tank body 1. The stirring head of the homogenizing and stirring device 12 extends into the bottom of the tank body 1. By providing a homogenizing and stirring device 12 at the bottom of the tank body 1, the uniformity of the discharge can be ensured, the problem of uneven mixing in certain areas can be avoided, and the material discharge can be accelerated, reducing the material residue at the bottom of the tank.

[0045] To prevent the addition of too much polymer plasticizer at once, it is necessary to add a fixed amount of material in batches. Accordingly, a number of support leg assemblies are arranged at intervals along the circumference at the bottom of the tank body 1. The support leg assembly includes a first support leg 13, a weighing module 14 disposed at the bottom of the first support leg 13, and a second support leg 15 disposed at the bottom of the weighing module 14.

[0046] By setting a weighing module 14 in the support leg assembly, the weight of each batch of material added to the tank 1 can be detected, and the amount of material added can be fed back to control the amount of material added in batches, so as to avoid adding too much material at one time, which would lead to excessively high local concentration and affect the uniformity of mixing.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
