Description

Technical Field

[0001] The present application relates to the technical field of composite material processing, and in particular to a device for preparing light composite material mixture. Background Art

[0002] The light composite material mixing and preparation device is a device used to manufacture light composite materials. These materials are usually used in aerospace, automobile, construction and other fields, and have the advantages of light weight, high strength and corrosion resistance. The mixing and preparation device is mainly used to evenly mix different materials (such as fibers, resins, additives, etc.) to form composite materials.

[0003] At present, when lightweight composite material raw materials are mixed and processed, if the raw materials are put into the mixing box too quickly, a large amount of raw materials will quickly enter and entrain air to the bottom of the raw materials, and bubbles will be generated in the mixing process. The air bubbles will weaken the mechanical strength and durability of the composite material (the gaps formed by the air bubbles in the composite material will cause local stress concentration, reduce the bearing capacity of the area, and easily crack and break. The presence of air bubbles inside the material makes the structure of the material loose, thereby reducing the overall mechanical strength and stiffness). Therefore, a mixing preparation device for composite material processing is designed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] The present application embodiment discloses a lightweight composite material mixing preparation device. Figure 1-4 , a lightweight composite material mixing and preparation device, including a mixing box 1, wherein both sides of the upper end of the mixing box 1 are fixedly connected to a feed pipe 14, the upper end of the mixing box 1 is rotatably connected to a mounting rod 4, the mounting rod 4 is slidably connected to a mounting ring 5, and the outer wall of the mounting ring 5 is fixedly connected to a guide plate 6, and the guide plate 6 is arranged to guide the raw material to fall along the inner wall, so that the raw material falls slowly, and avoids air being entrained when falling quickly, so that bubbles are generated during stirring and mixing, and both sides of the upper end of the mounting ring 5 are slidably connected to an adjusting tube 7, and the upper end of the adjusting tube 7 is threadedly connected to a threaded rod 8, and the upper end of the threaded rod 8 is rotatably connected to the inner wall of the mixing box 1. The adjusting tube 7 is driven down by the threaded rod 8, and the mounting ring 5 at the lower end is pushed down, so that the mounting ring 5 drives the guide plate 6 to descend, and the guide plate 6 will cover the raw material after it descends, reducing the range of contact between the raw material and the air, thereby further reducing the possibility of bubbles generated by mixing the raw material with air during stirring;

[0022] By adopting the above technical solution, the guide plate 6 is in a truncated cone shape, and the guide plate 6 and the mixing box 1 are adapted, such as Figure 3 and Figure 1 As shown, the side of the truncated cone-shaped guide plate 6 is close to the inner wall of the mixing box 1, and a certain gap is left, so that the raw materials can be discharged along the inner wall.

[0023] By adopting the above technical solution, the upper end of the threaded rod 8 passes through the inner wall of the mixing box 1 and is fixedly connected to the No. 1 gear 9. One side of the No. 1 gear 9 engages with the No. 2 gear 10. The middle part of the upper end of the No. 2 gear 10 is fixedly connected to the rotating rod 11. The No. 2 gear 10 can be driven to rotate by the rotating rod 11, so that the No. 2 gear 10 drives the No. 1 gear 9 to rotate, thereby driving the lower end threaded rod 8 to rotate.

[0024] By adopting the above technical solution, the first gear 9 and the second gear 10 are both rotatably connected to the protection frame 15, and the protection frame 15 is fixedly installed on the upper end of the mixing box 1 to protect the first gear 9 and the second gear 10.

[0025] By adopting the above technical solution, the upper end of the rotating rod 11 is fixedly connected to the rotating handle 12, the two sides of the rotating rod 11 are fixedly connected to the connecting rods, and one side of the connecting rods is fixedly connected to the cover plate 13. The rotating handle 12 can be rotated to drive the cover plate 13 to rotate and cover the feed port 14, so that the inner wall of the mixing box 1 is relatively sealed, reducing the entry of air, thereby reducing the possibility of bubble generation.

[0026] By adopting the above technical solution, the servo motor 2 is fixedly connected to the bottom of the mixing box 1, the output end of the servo motor 2 is fixedly connected to the stirring rod 3, and the upper end of the stirring rod 3 is fixedly connected to the mounting rod 4, which is used to stir and mix the raw materials in the mixing box 1.

[0027] By adopting the above technical solution, a slide groove 51 is opened at the upper end of the mounting ring 5, and a slider 71 is slidably connected in the slide groove 51. The upper end of the slider 71 is fixedly connected to the adjusting tube 7, so that the mounting ring 5 can rotate when driven by the mounting rod 4 without affecting the adjusting tube 7.

[0028] The implementation principle of a lightweight composite material mixing preparation device in the embodiment of the present application is as follows: the raw materials required for mixing are poured in from two feeding pipes 14 respectively. After the raw materials are poured in, they will fall on the guide plate 6. At this time, the servo motor 2 is started to drive the stirring rod 3 to rotate, and the stirring rod 3 drives the mounting rod 4 to rotate slowly, so that the mounting rod 4 drives the mounting ring 5 to rotate, and the mounting ring 5 drives the guide plate 6 to rotate, so that the guide plate 6 drives the upper raw materials to rotate and fall from the side of the guide plate 6. When the guide plate 6 drives the raw materials to rotate, the two raw materials are mixed, thereby playing a role of pre-mixing and improving the mixing efficiency. The raw materials will fall along the inner wall of the mixing box 1. After being guided to the inner wall of the mixing box 1, the materials will be more evenly distributed in the mixing box 1, which is conducive to the full contact and mixing of the various parts of the materials during the mixing process. Compared with direct falling, the materials falling along the wall are more easily constrained by the boundary, reducing the shear force during the mixing process, which is conducive to maintaining the integrity and performance of the materials. Moreover, falling along the inner wall also reduces the possibility of bubble generation due to the reduced contact area between the raw materials and the air.

[0029] After the falling is completed, the handle 12 can be rotated to drive the rotating rod 11 to rotate 90 degrees, and the rotating rod 11 drives the cover plate 13 to rotate, so that the cover plate 13 rotates to cover the feed pipe 14. Figure 1 As shown, a relatively sealed environment is formed, thereby reducing the amount of air entering the mixing box 1 and reducing the possibility of bubbles being generated during mixing. The second gear 10 drives the first gear 9 on both sides to rotate, so that the first gear 9 drives the threaded rod 8 to rotate, and the threaded rod 8 drives the regulating tube 7 to descend, and pushes the mounting ring 5 at the lower end to descend, so that the mounting ring 5 drives the guide plate 6 to descend. After the guide plate 6 descends, it will cover the raw materials, reducing the range of contact between the raw materials and the air, thereby further reducing the possibility of bubbles generated by the raw materials mixing with the air during stirring.
