Description

Technical Field

[0001] This utility model relates to the field of water-based adhesive mixing technology, specifically to a multi-axis mixing mechanism for water-based adhesive mixing. Background Technology

[0002] Water-based adhesive raw materials are widely used in chemical, coating, and adhesive industries. Their production process typically requires mixing using a stirring device to ensure uniform dispersion and stability of the components. Currently, most commercially available water-based adhesive raw material mixing utilizes a single-shaft stirring device. This device uses a single impeller rotating within the mixing vessel to generate shearing and circulating flow, thereby achieving initial mixing of the raw materials. However, single-shaft agitators have significant limitations in practical applications. First, because the flow field generated by a single impeller is relatively fixed, weak flow "dead zones" easily form on the vessel walls, bottom, and near the liquid surface. These dead zones cause the fillers (such as pigments and stabilizers) to settle or flocculate, leading to problems such as product inhomogeneity, stratification, and scaling, affecting the quality and consistency of the final product. Second, a key function of agitation is to enhance heat transfer. When exothermic reactions or water evaporation are required later, the material easily forms a layer of scale or deposits on the vessel walls. This scale does not participate in mixing, affecting heat transfer and proportioning, and is difficult to clean, further impacting production efficiency and product performance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a multi-axis stirring mechanism for mixing water-based adhesives, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A multi-axis mixing mechanism for water-based adhesives includes a U-shaped frame. A support platform is symmetrically and fixedly connected to the top surface of the U-shaped frame. The top surface of the support platform has a positioning groove. A mixing component is installed between two sets of support platforms. A lifting component is installed on the top surface of the U-shaped frame, and a mixing component is installed on one side of the lifting component. The mixing component includes a gear cylinder. A mixing motor is fixedly connected to the top surface of the gear cylinder. The output end of the mixing motor is rotatably connected to a drive shaft via a worm gear and worm wheel. A drive shaft is rotatably connected to the middle of the gear cylinder. A planetary disc is fixedly connected to one end of the drive shaft. A planetary disc is rotatably connected inside the gear cylinder. An internal gear ring is fixedly connected inside the gear cylinder. One end of the mixing component is connected to the internal gear ring.

[0005] Compared with the prior art, this utility model has the following advantages: 1. By combining the mixing and stirring components, a multi-axis stirring mode of revolution and rotation is formed. That is, the planetary turntable drives the wall scraping component and the stirring component to revolve around the planet, and the stirring component rotates by meshing with the internal toothed ring, eliminating dead zones and improving the uniformity of mixing. At the same time, when the wall scraping component rotates with the planetary turntable, it can scrape off the raw materials attached to the inner wall and bottom of the mixing cylinder, avoiding raw material residue, reducing waste, ensuring that the raw materials are fully involved in the mixing process, and reducing the difficulty of subsequent cleaning. 2. The lifting component can drive the stirring component to move up and down. During stirring, the stirring component is inserted into the mixing drum. After stirring is completed, the stirring component is raised to facilitate cleaning of the stirring component. At the same time, the positioning slot of the support plate fixes the mixing component, which facilitates the loading and unloading of the mixing component and subsequent feeding.

[0009] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0010] As an embodiment of this utility model, in order to solve the technical problems in the background art, the following multi-axis stirring mechanism for mixing water-based adhesives is provided: Combination Figures 1-7 As shown, the multi-axis mixing mechanism for water-based adhesives provided by this utility model includes a U-shaped frame 100. A support platform 200 is symmetrically and fixedly connected to the top surface of the U-shaped frame 100. A positioning groove 300 is provided on the top surface of the support platform 200. A mixing component 400 is installed between the two sets of support platforms 200. A lifting component 500 is installed on the top surface of the U-shaped frame 100, and a mixing component 600 is installed on one side of the lifting component 500. The mixing component 600 includes a gear cylinder 601, and a mixing motor 602 is fixedly connected to the top surface of the gear cylinder 601. The output end of the stirring motor 602 is rotatably connected to the drive shaft 603 via a worm gear and worm wheel. The drive shaft 603 is rotatably connected to the middle of the gear cylinder 601. One end of the drive shaft 603 is fixedly connected to a planetary disk 604. The planetary disk 604 is rotatably connected inside the gear cylinder 601. A wall scraping component is installed in the middle of the bottom surface of the planetary disk 604. Stirring components are installed inside the planetary disk 604 and on both sides of the wall scraping component. An internal gear ring 605 is fixedly connected inside the gear cylinder 601. One end of the stirring component is connected to the internal gear ring 605.

[0011] In one embodiment of this utility model, by combining a "mixing component + stirring component", the gear cylinder, drive shaft, planetary disc, wall scraping component, stirring component and internal gear ring in the stirring component cooperate to form a multi-axis stirring mode of "revolution + rotation" (the planetary disc drives the wall scraping component and stirring component to revolve, and the stirring component meshes with the internal gear ring to achieve rotation), eliminating stirring dead corners and improving mixing uniformity; when the wall scraping component rotates with the planetary disc, it can scrape off the raw materials attached to the inner wall and bottom of the mixing cylinder to avoid raw material residue, which not only reduces waste, but also ensures that the raw materials fully participate in the mixing process, and reduces the difficulty of subsequent cleaning; Meanwhile, the lifting component can drive the stirring component to move up and down. During stirring, the stirring component is inserted into the mixing drum. After stirring is completed, the stirring component is raised to facilitate cleaning of the stirring component. At the same time, the positioning slot of the support plate fixes the mixing component, which facilitates the loading and unloading of the mixing component and subsequent material feeding.

[0012] In one embodiment of the present invention, the wall scraping component includes a wall scraping shaft 606. The wall scraping shaft 606 is fixedly connected to the center of the bottom surface of the planetary turntable 604. A C-shaped wall scraping rod 607 is fixedly connected to the bottom surface of the wall scraping shaft 606. An extension rod 608 is fixedly connected to the upper surface of the wall scraping shaft 606. An inner scraper 609 is fixedly connected to one end of the extension rod 608.

[0013] The C-shaped scraper rod at the bottom of the scraper shaft can fit against the inner wall of the bottom of the mixing drum and scrape off the residual material at the bottom as the scraper shaft rotates; the extension rod at the top of the scraper shaft is connected to the inner scraper, which can fit against the side wall of the mixing drum and scrape off the residual material on the side wall at the same time, achieving all-round cleaning of "bottom + side wall" and completely avoiding material adhesion and waste; While rotating to clean, the C-shaped scraper, extension rod, and inner scraper can also stir the raw materials in the mixing drum, further assisting the main stirring component to improve the uniformity of raw material mixing, thus achieving the dual function of "cleaning + stirring".

[0014] In one embodiment of the present invention, the stirring component includes a stirring shaft 610, which is symmetrically rotatably connected to a planetary turntable 604. Stirring rods 611 are fixedly connected at equal intervals to the lower part of the surface of the stirring shaft 610. Planetary gears 612 are fixedly connected to the upper part of the surface of the stirring shaft 610. The planetary gears 612 are meshed with an internal gear ring 605. V-shaped stirring paddles 613 are fixedly connected to both sides of the stirring rods 611.

[0015] When the planetary disc drives the stirring shaft to revolve, the planetary gear on the upper part of the stirring shaft meshes with the internal gear ring fixed inside the gear cylinder. The meshing action causes the planetary gear to move around the internal gear ring, which in turn drives the stirring shaft to rotate. The stirring rod on the surface of the stirring shaft "revolves and rotates" with the stirring shaft, which greatly improves the stirring range and intensity, avoids the separation of raw materials, and ensures that the water-based adhesive raw materials are mixed evenly. The stirring rods, which are fixed at equal intervals on the lower part of the stirring shaft surface, can make the stirring force evenly applied to the raw materials in different areas of the mixing drum, further ensuring the consistency of mixing and avoiding the problem of insufficient mixing of local raw materials. The V-shaped stirring rod has a symmetrical inclined layout of two rods. When it rotates, it will form a two-way cross convection, which will cause the material on both sides to converge towards the center and flow upward / downward along the inclined direction of the rod. This breaks the limitation of "vortex stirring" in one direction. At the same time, it can also prevent the emulsion structure from being broken up and maintain the stability of the material.

[0016] In one embodiment of the present invention, the mixing component 400 includes a mixing cylinder 401, a fixing ring 402 is fixedly connected to the surface of the mixing cylinder 401, a handle 403 is symmetrically fixedly connected to the surface of the fixing ring 402, and a discharge pipe 404 is fixedly connected to the bottom surface of the mixing cylinder 401, and a valve is installed inside the discharge pipe 404.

[0017] The fixing ring on the surface of the mixing drum can be locked into the positioning slot of the support plate to achieve precise fixation of the mixing components and the U-shaped frame, preventing the mixing drum from shaking during mixing and ensuring the stability of the mixing process; The symmetrical handles on the surface of the fixing ring make it easy for workers to grab the equipment and easily remove or put the mixing components from the positioning slot. This facilitates the transfer of the mixing drum for unloading after mixing, or the removal of the mixing drum for separate cleaning. The discharge pipe at the bottom of the mixing drum, in conjunction with the built-in valve, allows for precise control of the timing and speed of material discharge. This prevents material leakage during mixing and simplifies the discharge process (eliminating the need to tilt the mixing drum), reducing the risk of material spillage during discharge.

[0018] In one embodiment of this utility model, the lifting assembly 500 includes a guide column 501. The top surface of the U-shaped frame 100 is fixedly connected to the guide column 501. A guide groove 502 is provided on the upper part of one side of the guide column 501. A lifting threaded rod 503 is rotatably connected in the guide groove 502. A lifting block 504 is threadedly connected to the surface of the lifting threaded rod 503. One end of the lifting block 504 is fixedly connected to the surface of the gear cylinder 601. A lifting motor 505 is fixedly connected to the top surface of the guide column 501. The output end of the lifting motor 505 is fixedly connected to the lifting threaded rod 503.

[0019] The lifting motor on the top surface of the guide column drives the lifting threaded rod to rotate. The lifting threaded rod is threaded with the lifting block, which converts the rotational motion of the motor into the linear motion of the lifting block, and can quickly move the mixing component up and down. By controlling the start and stop of the lifting motor, the insertion depth of the mixing component can be precisely controlled to avoid collision between the mixing component and the mixing drum, or insufficient mixing due to insufficient insertion. The guide groove on one side of the guide column guides the lifting block, preventing it from shifting during movement and ensuring that the mixing component always moves vertically, further improving the accuracy of the alignment between the mixing component and the mixing cylinder.

[0020] Working principle and usage process of this utility model: In use: First, the staff put the prepared water-based adhesive raw materials into the mixing drum 401. At this time, the valve in the feed pipe 404 is closed, so the raw materials are all inside the mixing drum 401. Then, the lifting motor 505 is started. As the lifting motor 505 works, it will drive the lifting threaded rod 503 to rotate. When the lifting threaded rod 503 rotates, it will drive the lifting block 504 to move downward. When the lifting block 504 moves downward, it will drive the mixing component 600 to move downward. When the lower end of the mixing component 600 is completely inserted into the mixing drum 401, the lifting motor 505 is stopped. Start the stirring motor 602, which drives the transmission shaft 603 to rotate. When the transmission shaft 603 rotates, it drives the planetary disk 604 to rotate. When the planetary disk 604 rotates, it drives the scraper shaft 606 and the stirring shaft 610 to rotate respectively. Note that at this time, both the scraper shaft 606 and the stirring shaft 610 revolve around the gear cylinder 601. When the scraper shaft 606 rotates, it starts to drive the C-shaped scraper rod 607, the extension rod 608, and the inner scraper 609 to rotate. When the C-shaped scraper rod 607 rotates, it scrapes the bottom inner wall of the mixing cylinder 401, while the inner scraper 609... The rotation scrapes the inner wall of the mixing cylinder 401. At the same time, the rotation of the C-shaped scraper 607, the extension rod 608 and the inner scraper 609 can also stir the raw materials in the mixing cylinder 401. When the planetary turntable 604 rotates, it will drive the stirring shaft 610 to rotate in the gear cylinder 601. When the stirring shaft 610 rotates, it will cause the planetary gear 612 to travel on the inner gear ring 605. When the planetary gear 612 travels, it will start to drive the stirring shaft 610 to rotate. When the stirring shaft 610 rotates, it will drive the stirring rod 611 to rotate, and start to stir the raw materials in the mixing cylinder 401. After mixing is complete, start the lifting motor 505. The lifting motor 505 drives the mixing assembly 600 to move upward through the lifting threaded rod 503, so that the mixing area in the mixing assembly 600 is moved out of the mixing drum 401, which makes it easier for the staff to clean the mixing assembly 600 later. During material feeding, there are two methods: First, the worker opens the valve inside the feeding pipe 404, at which point the mixed raw material is discharged from the feeding pipe 404. Second, the worker uses external equipment to hold the handle 403 and lift it upwards, causing the handle 403 to disengage from the positioning slot 300. The worker can then remove the entire mixing component 400 from between the two sets of support plates 200. After removal, it is convenient for the worker to feed the material and for subsequent cleaning.
