[0020] 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.
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] Reference Figure 1-4This invention provides a composite material mixing device, including a working platform 1. Two mixing tank bodies 2 are fixedly connected to the working platform 1. A stirring shaft 3 is rotatably connected inside each mixing tank body 2. A first stirring blade 4 is fixedly connected to the stirring shaft 3. A sleeve shaft 5 is rotatably connected inside the mixing tank body 2, sleeved on the outside of the stirring shaft 3 and rotating in the opposite direction to the stirring shaft 3. A second stirring blade 6 is fixedly connected to the periphery of the sleeve shaft 5. A drive assembly is installed in the mixing tank body 2 to drive the stirring shaft 3 and the sleeve shaft 5 to rotate. An observation port 7 is opened at the top of the mixing tank body 2, and a feed port 8 and a discharge port 9 are opened at the bottom of the mixing tank. By setting two mixing tank bodies 2 on the working platform 1 to mix raw materials of different components respectively, and then mixing the mixture from the two mixing tank bodies 2 again, the mixing time is reduced. At the same time, the sleeve shaft 5 and the second stirring blade 6, which rotate in the opposite direction to the stirring shaft 3, are set inside the mixing tank body 2. The drive assembly drives the first stirring blade 4 and the second stirring blade 6 to rotate in opposite directions, which can fully mix the raw materials in the mixing tank body 2, shorten the mixing time, and improve the mixing efficiency.
[0023] The optimized design includes a control box 10 fixedly mounted on the top of the mixing tank body 2. The top ends of the stirring shaft 3 and the sleeve shaft 5 pass through the top wall of the mixing tank body 2 and are located inside the control box 10. The top end of the stirring shaft 3 is rotatably connected to the top wall of the control box 10. A rotating drum 11 is fixedly connected to the periphery of the stirring shaft 3. A first bevel gear 12 is mounted on one end of the sleeve shaft 5 and on the periphery of the rotating drum 11. The first bevel gear 12 on the sleeve shaft 5 is located below another bevel gear. The two first bevel gears 12 are arranged opposite to each other. The rotating drum 11 is fixedly connected to the first bevel gear 12. A second bevel gear 13 is rotatably connected to the side wall of the control box 10. The second bevel gear 13 is located between the two first bevel gears 12 and meshes with the first bevel gear 12. A drive motor 14 is fixedly connected to the top of the control box 10. The output shaft of the drive motor 14 is fixedly connected to the stirring shaft 3. The drive motor 14 drives the stirring shaft 3 to rotate, which in turn drives the first stirring blade 4 to rotate. At the same time, the stirring shaft 3 drives the rotating drum 11 to rotate, and the rotating drum 11 drives the first bevel gear 12 to rotate. In turn, the second bevel gear 13 drives another bevel gear 12 to rotate, and the first bevel gear 12 drives the sleeve shaft 5 to rotate, thereby driving the second stirring blade 6 to rotate. Since the two first bevel gears 12 rotate in opposite directions, the second stirring blade 6 rotates in the opposite direction to the first stirring blade 4, thereby fully mixing the raw materials in the mixing tank body 2.
[0024] In a further optimized design, a support frame 15 is fixedly connected inside the control box 10. The first bevel gear 12, located below, is mounted on the support frame 15 and rotatably engages with it. The sleeve shaft 5 passes through the first bevel gear 12 and slides along its axis, with its top end sliding within the rotating drum 11. A control component that drives the sleeve shaft 5 to move up and down is installed inside the mixing tank body 2. The sleeve shaft 5 passes through the first bevel gear 12 and slides along its axis, allowing the first bevel gear 12 to drive the sleeve shaft 5 to rotate without affecting its vertical sliding.
[0025] The scheme is further optimized. The control components include a control panel 16 rotatably installed inside the mixing tank body 2, a lifting plate 17 rotatably connected to the circumference of the sleeve shaft 5, a control plate 18 fixedly connected to the side of the lifting plate 17 near the control panel 16, a horizontally arranged strip groove 19 opened on the control plate 18, a connecting column 20 rotatably connected to the side of the end face of the control panel 16, and the connecting column 20 slidingly located in the strip groove 19; a limit rod 21 is fixedly connected to the top wall of the mixing tank body 2, and the limit rod 21 is slidably installed through the lifting plate 17; a control motor 22 that drives the control panel 16 to rotate is fixedly connected to the outer wall of the mixing tank body 2. The control motor 22 drives the control disk 16 to rotate, which in turn drives the connecting column 20 on the control disk 16 to move. The connecting column 20 will undergo horizontal and vertical displacement as it rotates with the control disk 16. When horizontal displacement occurs, it slides in the strip groove 19. When vertical displacement occurs, it drives the lifting plate 17 to move up and down through the control plate 18, which in turn drives the sleeve shaft and the second stirring blade 6 to move up and down. This causes the second stirring blade 6 to move up and down during rotation, which fully stirs the raw materials in the mixing tank body 2.
[0026] In a further optimized design, a dispersing shaft 23 is rotatably connected inside the mixing tank body 2. Two dispersing discs 24 are fixedly mounted on the dispersing shaft 23, and a second stirring blade 6 is located between the two dispersing discs 24. A dispersing motor 25, which drives the dispersing shaft 23 to rotate, is fixedly installed on the top wall of the mixing tank body 2. The dispersing motor 25 drives the dispersing shaft 23 to rotate, which in turn drives the dispersing discs 24 to rotate. Furthermore, the dispersing discs 24 are metal discs with ratchet teeth, which can fully disperse the raw materials.
[0027] In a further optimized design, the discharge port 9 at the bottom of one mixing tank body 2 is connected to another mixing tank body 2 via a connecting pipe, on which a conveying pump 26 is installed. The discharge port 9 of the other mixing tank body 2 is connected to a discharge pipe 27, within which a filter 28 is installed. The conveying pump 26 transports the mixed raw materials from one mixing tank body 2 to the other mixing tank 2 for further mixing. By mixing the raw materials separately in the two mixing tank bodies 2 before mixing them together, thorough mixing of the raw materials can be ensured, effectively avoiding the problem of insufficient mixing caused by continuously adding raw materials during single-tank mixing.
[0028] The design is further optimized by incorporating a double-layer structure for the side and bottom walls of the mixing tank body 2, with an insulation layer 29 within the double-layer structure. This insulation layer ensures the temperature of the mixing tank body 2 during the mixing process, preventing temperature drops in winter from affecting the mixing effect, and also preventing excessively high temperatures in summer from causing reactions between internal raw materials that could negatively impact their quality.
[0029] The design was further optimized so that the main body 2 of the mixing tank runs through the working platform 1 and is fixedly connected to the working platform 1 in the middle; a ladder is fixedly installed on one side of the working platform 1. This allows workers to move to the top of the working platform 1 via the ladder, facilitating observation of the interior of the mixing tank 2 through the observation port 7.
[0030] The design has been further optimized by installing a viscometer 30 at observation port 7. This allows for real-time monitoring of the mixture's viscosity, facilitating timely adjustments.
[0031] The scheme has been further optimized by installing two raw material barrels under the working platform 1. The different raw materials in the two raw material barrels are transported to the two mixing tank bodies 2 for separate mixing.
[0032] The working process of this utility model is as follows: When in use, raw materials of different components are put into two different mixing tank bodies 2 for preliminary mixing. The drive motor 14 is started, and the drive motor 14 drives the stirring shaft 3 to rotate, which in turn drives the first stirring blade 4 to rotate. At the same time, the stirring shaft 3 drives the rotating drum 11 to rotate during the rotation. The rotating drum 11 drives the second bevel gear 13 to rotate through the first bevel gear 12, which in turn drives the other first bevel gear 12 to rotate in the opposite direction, thereby driving the sleeve shaft 5 to rotate in the opposite direction to the stirring shaft 3. The stirring shaft 3 drives the second stirring blade 6 to rotate. Simultaneously, the control motor 22 and the dispersion motor 25 are started. The control motor 22 drives the control disk 16 to rotate. During the rotation of the control disk 16, the connecting column 20 is displaced. When the connecting column 20 is displaced in the horizontal direction, it slides horizontally in the strip groove 19. When it is displaced in the vertical direction, the control plate 18 drives the lifting plate 17 to move up and down, which in turn drives the sleeve shaft 5 to move up and down, so that the second stirring blade 6 can move up and down during the rotation, which can fully mix the raw materials in the mixing tank body 2. After the raw materials in the two mixing tank bodies 2 are mixed evenly, the mixture in one mixing tank body 2 is transported to the other mixing tank body 2 for further mixing.
