Adhesive mixing uniformity enhancement device

Abstract

This utility model discloses an adhesive mixing uniformity enhancement device, belonging to the technical field of adhesive production equipment. The device includes a mixing tank, a cooling tank surrounding it, a mixing assembly containing auger blades and a scraper within the mixing tank, and a stirring rod within the cooling tank. Its core feature is that the mixing assembly and the stirring rod are synchronously driven by the same mixing and cooling drive mechanism, achieving a synergistic effect of mixing, scraping, and enhanced cooling. This utility model eliminates mixing dead zones through the scraping action of the scraper, and simultaneously, through the stirring rod's agitation of the cooling medium combined with forced circulation, efficiently dissipates the heat of reaction, solving the problem of uneven mixing caused by adhesive sticking to the walls and heat accumulation, significantly improving the uniformity and quality of the product.

Description

Technical Field

[0001] This utility model relates to the technical field of adhesive production equipment, and more specifically, to an adhesive mixing device. Background Technology

[0002] In the production and preparation of adhesives, especially two-component reactive adhesives, thorough and uniform mixing is a key step in ensuring their final performance. Existing mixing equipment often faces two interrelated technical challenges when handling such materials. First, because many adhesives have high viscosity, the material tends to adhere to the inner wall of the mixing container during stirring, forming a "boundary layer" that is difficult to stir. This not only wastes raw materials but also creates mixing dead zones, leading to uneven composition of the final product. Second, the mixing process of adhesives is often accompanied by intense exothermic chemical reactions. If the generated heat cannot be effectively dissipated in time, it will cause a temperature gradient inside the material. Excessively high local temperatures can cause premature curing, bubble formation, or performance degradation of the material, seriously affecting the uniformity and quality of the finished product.

[0003] To address the heat dissipation problem, some equipment uses a cooling jacket outside the mixing tank. However, if the cooling medium is stationary or flows slowly inside the jacket, the heat exchange efficiency between it and the mixing tank wall will be greatly reduced due to the formation of a thermal boundary layer. This makes it impossible to achieve rapid and uniform cooling and fundamentally solve the problem of local overheating. Existing technologies lack an integrated structure that can effectively combine wall scraping and material removal with efficient heat dissipation, resulting in significant deficiencies in enhancing mixing uniformity.

[0004] Therefore, this invention proposes an adhesive mixing uniformity enhancement device to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of uneven mixing and unstable product performance caused by material sticking to the wall and heat accumulation in the existing adhesive mixing device, the present invention aims to provide an adhesive mixing uniformity enhancement device with improved structure that can effectively solve the above problems.

[0006] This utility model provides an adhesive mixing uniformity enhancement device, including: a mixing tank, a cooling tank, a mixing component disposed inside the mixing tank; a mixing and cooling drive mechanism and a stirring rod disposed inside the cooling tank.

[0007] The mixing assembly includes auger blades for mixing materials and scrapers for scraping material off the inner wall of the mixing tank.

[0008] Furthermore, the cooling tank covers the outside of the mixing tank, and the mixing and cooling drive mechanism is connected to the mixing component and the stirring rod to synchronously drive the mixing component to rotate in the mixing tank and the stirring rod to rotate in the cooling tank.

[0012] Preferably, the device further includes a body and a lifting mechanism disposed on the body; the hybrid cooling drive mechanism is mounted on the lifting mechanism and is used to be lifted and lowered by the lifting mechanism.

[0016] This utility model has the following beneficial effects: 1.

[0017] 2.

[0018] 3. This utility model, by setting up an independent lifting mechanism to drive the entire mixing and cooling working head to move vertically, solves the problems of existing mixing devices having a fixed structure, poor applicability, and difficulty in matching mixing containers of different specifications. It achieves the technical effect of flexible overall structure and strong versatility, and expands the application range of the device. Attached Figure Description

[0021] 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.

[0022] Please refer to Figures 1 to 4This utility model provides an adhesive mixing uniformity enhancement device, which aims to solve the problems of uneven adhesive mixing and local overheating caused by the lack of effective synchronous cooling and wall scraping structures in the prior art.

[0023] like Figure 1 and Figure 2 As shown, the adhesive mixing uniformity enhancement device includes a body 1, a lifting mechanism 2, a cooling mechanism 3, a fixing frame 4, a cooling tank 5, and a mixing tank 6 mounted on the body 1. The body 1 serves as the mounting base for the entire device. The lifting mechanism 2 is used to drive the core working components of the device to achieve vertical lifting. The mixing tank 6 is used to contain the adhesive material to be mixed. The cooling tank 5 covers the outside of the mixing tank 6, forming a jacket structure for containing the cooling medium. The core of this device is that the mixing component inside the mixing tank 6 and the stirring rod 304 inside the cooling tank 5 are driven by the same mixing and cooling drive mechanism, so that the mixing of the material, the scraping of the inner wall of the mixing tank 6, and the stirring of the cooling medium in the cooling tank 5 can be carried out simultaneously. The mixing component includes a screw conveyor blade 311 for three-dimensional stirring of the material and a scraper 305 for scraping off the material adhering to the inner wall of the mixing tank 6.

[0024] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment lies in the cooperative working structure formed between the mixing and cooling drive mechanism, the mixing component and the cooling mechanism 3 of the adhesive mixing uniformity enhancement device.

[0025] Please refer to the following carefully. Figure 3 and Figure 4 The core structure will be described in detail below: The mixing and cooling drive mechanism of the device includes a second motor 301, a rotating short rod 302 connected to the output end of the second motor 301, and a rotating rod 303 driven by the rotating short rod 302. The axis of the rotating rod 303 is perpendicular to the axis of the rotating short rod 302. The rotating rod 303 extends into the interior of the mixing tank 6. The auger blade 311 is fixedly mounted on the outer peripheral wall of the rotating rod 303. The scraper 305 is mounted on the moving part of the mixing component and its working edge abuts against the inner wall of the mixing tank 6. The stirring rod 304 is fixedly connected to the rotating short rod 302 and extends into the interior of the cooling tank 5. This structure allows the second motor 301 to drive the rotating rod 303 and the stirring rod 304 to rotate simultaneously through the rotating short rod 302 when the second motor 301 is started. This enables the composite motion of the auger blade 311 and the scraper 305 in the mixing tank 6 and the stirring motion of the stirring rod 304 in the cooling tank 5 to be carried out synchronously, ensuring the coupling of efficient mixing and uniform cooling. Meanwhile, the water storage tank 309 of the cooling mechanism 3 is connected to the lower part of the cooling tank 5 through the water inlet pipe 310, and the upper part of the cooling tank 5 is connected to the inlet of the water pump 307 through the water outlet pipe 306. The outlet of the water pump 307 is connected to the water storage tank 309 through the flow pipe 308, forming a complete forced circulation cooling circuit. This circuit, together with the stirring action of the stirring rod 304, greatly improves the heat exchange efficiency of the cooling medium.

[0026] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In order to achieve the height adjustability of the entire mixing and cooling components to adapt to mixing tanks 6 of different sizes, the device also includes a body 1 and a lifting mechanism 2 set on the body 1. The mixing and cooling drive mechanism and its driven mixing components and stirring rod 304 are all mounted on the lifting mechanism 2 through a fixed frame 4 so that the entire unit can be vertically lifted by the lifting mechanism 2. As a specific lifting implementation method, the lifting mechanism 2 includes a first motor 201 as a power source, a rotating rod 202 driven by the first motor 201, a driving bevel gear 203 fixed on the rotating rod 202, a driven bevel gear 207 meshing with the driving bevel gear 203, a threaded rod 206 coaxially fixed with the driven bevel gear 207, and a connecting plate 205 threadedly engaged with the threaded rod 206. The fixed frame 4 is fixedly connected to the connecting plate 205, thereby converting the rotational motion of the threaded rod 206 into the linear lifting motion of the fixed frame 4. To further improve the stability of the lifting process, the lifting mechanism 2 also includes a fixing plate 204 for securely mounting the driven bevel gear 207, and a limiting plate 208 for guiding and limiting the lifting movement of the fixed frame 4. The limiting plate 208 ensures that the fixed frame 4 maintains a vertical posture during movement.

[0027] Working principle: The water inside the storage tank 309 is introduced into the cooling tank 5 through the inlet pipe 310, so that the cold water can surround the outside of the mixing tank 6. Then, the second motor 301 is turned on, which makes the rotating short rod 302 rotate, and then the multiple stirring rods 304 rotate synchronously, so that the cold water can be evenly distributed. As the rotating rod 303 rotates with the rotating short rod 302, the auger blades 311 rotate, which can mix the materials more thoroughly. The two scrapers 305 are installed to scrape off the material residue on the inner wall of the mixing tank 6. After working for a period of time, the temperature of the cold water in the cooling tank 5 rises. The water pump 307 is turned on, so that the water in the cooling tank 5 is discharged through the outlet pipe 306, flows through the circulation pipe 308 of the water pump 307 and enters the storage tank 309. The cold water is introduced back into the cooling tank 5 through the inlet pipe 310, thus realizing the circulation of cold water. The cooling mechanism 3 realizes the cooling of the materials inside the mixing tank 6. The first motor 201 is turned on, causing the rotating rod 202 to start rotating, which in turn causes the driving bevel gear 203 to rotate synchronously. The driving bevel gear 203 meshes with the driven bevel gear 207, causing the threaded rod 206 to rotate accordingly, which in turn drives the connecting plate 205 to move. Since the connecting plate 205 is fixedly connected to the fixed frame 4, the connecting plate 205 can drive the fixed frame 4 to move up and down along the threaded rod 206. Through the installation of the limiting plate 208, the fixed frame 4 and the connecting plate 205 can move vertically. Through the installation of the fixed plate 204, the driven bevel gear 207 can be securely installed. Through the installation of the lifting mechanism 2, the fixed frame 4 can adapt to mixing tanks 6 of different heights, which facilitates the operation of the machine body 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
