Description

Technical Field

[0001] This utility model belongs to the field of stirring and mixing technology, specifically a high-efficiency dispersion stirring and mixing kettle for composite prepreg resin. Background Technology

[0002] Prepregs are composites made by impregnating continuous fibers or fabrics with a resin matrix under strictly controlled conditions, resulting in a resin matrix and reinforcement. They have wide applications in aerospace, automotive, and construction industries. In the production process of composite prepregs, resin dispersion and mixing are crucial steps, directly affecting the prepreg's performance. Typically, mixing kettles use a transmission device to drive a stirring shaft to rotate and mix the materials. However, the fixed structure of the stirring shaft, rotating from the same position, leads to uneven mixing of materials at different heights and in different areas, affecting the resin dispersion. Such high-efficiency dispersion mixing kettles for composite prepregs are not suitable for mixing materials at different heights, thus impacting the mixing effect. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0026] like Figure 1 and Figure 2As shown, the present invention proposes a high-efficiency dispersion and mixing vessel for composite prepreg resin, including a reaction vessel 1. A feed pipe 2 is connected to one side of the outside of the reaction vessel 1, through which the material enters the interior of the reaction vessel 1. Discharge pipes 3 are evenly connected to both sides of the lower end of the reaction vessel 1. A support plate 4 is connected to one side of the interior of the reaction vessel 1, which supports the components in the stirring assembly 6. The stirring assembly 6 is connected to the upper end of the support plate 4.

[0027] like Figure 3 As shown, the stirring assembly 6 includes a rotating shaft 61 mounted on the upper end of the support plate 4. The lower end of the rotating shaft 61 extends through to the bottom of the support plate 4. A mixing plate 62 is connected to the outside of the rotating shaft 61. The rotation of the mixing plate 62 drives the material to rotate and mix. A dispersion hole 63 is opened at one end of the mixing plate 62. When the material passes through the dispersion hole 63, it breaks the dead zone of the material flow near the stirring rod, promotes the radial and axial circulation of the material, and enhances the uniformity of stirring and dispersion. A sliding groove 64 is opened on the outside of the rotating shaft 61. A moving plate 65 is connected to the upper end of the rotating shaft 61. Round rods 66 are connected through all four sides of the upper end of the moving plate 65. One end of the round rods 66 is connected to the top of the inner wall of the reactor 1. The moving plate 65 slides along the outside of the round rods 66. Under the sliding limit of 66, the moving plate 65 drives the rotating shaft 61 to move up and down in a straight line. The other end of the round rod 66 is connected to the support plate 4. A spring 67 is sleeved on the outside of the round rod 66. One end of the spring 67 is connected to the support plate 4. When the protruding end of the convex plate 613 contacts the moving plate 65, it drives the moving plate 65 to move upward. The moving plate 65 drives the spring 67 and the rotating shaft 61 to move upward, so that the spring 67 is in a stretched state. When the convex plate 613 is not in contact with the moving plate 65, under the elastic potential energy of the spring 67, the moving plate 65 moves downward. With the continuous rotation of the convex plate 613 and the cooperation of the spring 67, the moving plate 65 reciprocates up and down. The other end of the spring 67 is connected to one side of the moving plate 65.

[0028] like Figure 4 As shown, a support frame 68 is rotatably sleeved on the outside of the rotating shaft 61, supporting the worm gear 69. The lower end of the support frame 68 is connected to the support plate 4, and the worm gear 69 is rotatably connected to the upper end of the support frame 68. The worm gear 69 and the worm 610 have a transmission function. The rotation of the worm 610 drives the worm gear 69 to rotate. The worm gear 69 is fixedly sleeved on the outside of the rotating shaft 61. One end of the worm gear 69 is engaged with the worm 610, and one end of the worm 610 is connected to a transmission rod 611. One end of 611 is connected to a motor 612, which drives the worm gear 610 and the convex plate 613 to rotate simultaneously. One end of the motor 612 is connected to the support plate 4. The convex plates 613 are fixedly sleeved on both sides of the transmission rod 611. One end of the convex plate 613 is rotatably connected to a pulley 614. When one end of the convex plate 613 contacts the moving plate 65, it drives the pulley 614 to rotate, which greatly reduces the friction between the convex plate 613 and the moving plate 65 and improves the service life of the parts.

[0029] like Figure 5 As shown, a slider 615 is connected to the inner side of the worm gear 69. With the cooperation of the slider 615 and the slide groove 64, the moving plate 65 can drive the rotating shaft 61 to slide upward. At the same time, the worm gear 69 rotates, driving the rotating shaft 61 to rotate. Therefore, the rotating shaft 61 rotates while sliding up and down. The slider 615 is located inside the slide groove 64 and is slidably connected to the slide groove 64. Both sides of one end of the slider 615 are rotatably connected to ball bearings 616. The ball bearings 616 rotate under the sliding of the slider 615, reducing the friction between the slider 615 and the slide groove 64, thereby making it easier for the rotating shaft 61 to move up and down, and extending the service life of the slider 615.

[0030] like Figure 6 As shown, a stabilizing rod 617 is connected to the lower end of the rotating shaft 61. When the rotating shaft 61 moves up and down, it slides along the outside of the stabilizing rod 617. With the support of the stabilizing rod 617, the rotating shaft 61 is safer during rotation. The lower end of the stabilizing rod 617 is connected to the bottom of the inside of the reactor 1. One end of the stabilizing rod 617 extends through the inside of the rotating shaft 61 and is connected to a limiting plate 618. The limiting plate 618 limits the stabilizing rod 617, restricting one end of the stabilizing rod 617 to remain inside the rotating shaft 61, and preventing the rotating shaft 61 from separating from the stabilizing rod 617.

[0031] The implementation principle of the high-efficiency dispersion and mixing kettle for composite prepreg resin in this application embodiment is as follows: During use, the motor 612 drives the worm 610 and the convex plate 613 to rotate simultaneously. The worm 610 meshes with the worm wheel 69. Under the transmission action of the worm 610 and the worm wheel 69, the worm wheel 69 drives the rotating shaft 61 to rotate. The rotating shaft 61 drives the mixing plate 62 to rotate and mix the material. When the protruding end of the convex plate 613 contacts the moving plate 65, it drives the moving plate 65 to move upward. 65 drives the spring 67 and the rotating shaft 61 to move upward, so that the spring 67 is in a stretched state. When the convex plate 613 is not in contact with the moving plate 65, the elastic potential energy of the spring 67 causes the moving plate 65 to move downward. With the continuous rotation of the convex plate 613 and the cooperation of the spring 67, the moving plate 65 reciprocates up and down. With the cooperation of the slider 615 and the slide groove 64, the rotating shaft 61 moves up and down during the rotation. The movement of the rotating shaft 61 drives the mixing plate 62 to move up and down, so as to stir the materials at different heights.

[0032] The motor model can be YE2-6344-37KW, which is existing technology and widely used in society, so it will not be described in detail. All electrical components mentioned in this application are connected to an external power supply and control switch during use.

[0033] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
