Description

Technical Field

[0001] This utility model relates to the field of carbon fiber composite material mixing technology, and specifically to a high-efficiency mixing device for carbon fiber composite materials. Background Technology

[0002] The core raw material of carbon fiber composites consists of two parts: the reinforcement and the matrix. In some applications, auxiliary materials are added to optimize performance. Currently, during the mixing process of carbon fiber composite raw materials, when the raw materials are piled up in the equipment, it is difficult to turn them over between the upper and lower layers. This can easily lead to the formation of carbon fiber agglomerates, which is not conducive to the material's full contact with the matrix. This results in uneven internal properties of the composite material, which in turn reduces the mixing effect. Moreover, the difficulty in turning over the composite material raw materials requires more time for mixing, thus reducing the mixing efficiency. Utility Model Content

[0010] The beneficial effects of this utility model are as follows: 1.

This effectively reduces material accumulation and the difficulty of turning the material. Then, a servo motor is activated to drive the supporting rotating shaft to rotate, which in turn drives the spiral blades to rotate.

This avoids the inconvenience of turning the material due to accumulation, thereby increasing mixing efficiency. It also ensures good mixing efficiency, reduces the probability of agglomeration of the carbon fiber composite material raw materials, and guarantees good internal properties of the composite material.

[0017] like Figure 1-4As shown, a high-efficiency mixing device for carbon fiber composite materials includes a mixing chamber 1. Two support frames 2 are symmetrically fixedly installed at the bottom of the mixing chamber 1. A support shaft 12 is rotatably mounted on one side wall of the mixing chamber 1, and the support shaft 12 is located inside the mixing chamber 1. A servo motor 5 is fixedly installed on the outer side wall of the mixing chamber 1, and one end of the output shaft of the servo motor 5 is fixedly connected to one end of the support shaft 12. The servo motor 5 provides power for the mixing of the device. Inlet ports 4 are opened on the upper side of multiple mixing spaces on the mixing chamber 1, and inlet pipes 3 are fixedly installed inside the inlet ports 4. A sealing cover is provided on the inlet pipes 3.

[0018] Multiple partitioning mechanisms are fixedly installed on the side wall of the supporting shaft 12. The partitioning mechanism includes a supporting bearing 13, which is fixedly sleeved on the outer side wall of the supporting shaft 12. A supporting partition 10 is fixedly sleeved on the outer side wall of the supporting bearing 13. The supporting partition 10 is fixedly installed inside the mixing box 1. Sealing ring plates 11 are fixedly installed on both sides of the supporting partition 10, and the sealing ring plates 11 are sleeved on the outside of the supporting shaft 12. The sealing ring plates 11 can protect the supporting bearing 13. At the same time, the supporting partition 10 and the supporting bearing 13 can provide support for the supporting shaft 12, thereby ensuring the good stability of the supporting shaft 12.

[0019] Multiple mixing spaces are formed within the mixing chamber 1 by multiple supporting partitions 10. Raw materials are fed into these spaces through multiple feed pipes 3, effectively reducing material accumulation and simplifying material handling. A stirring mechanism is installed on the supporting shafts 12 within each mixing space of the mixing chamber 1. This mechanism includes a spiral blade 8, which is spirally mounted on the outer wall of the supporting shaft 12 and fixedly connected to it. Multiple material discharge holes 9 are provided on the side wall of the spiral blade 8, and multiple dispersing teeth are fixedly installed thereon. The material discharge holes 9 are arranged in a circular pattern on the side wall of the spiral blade 8, with equal spacing between them. The shearing and stirring action, achieved through the material discharge holes 9 and the dispersing teeth, improves the mixing effect of the raw materials.

[0020] The mixing box 1 has a discharge port 14 on the lower side of each of the multiple mixing spaces, and a discharge pipe 6 is fixedly installed on the lower side of each of the multiple discharge ports 14. A guide strip opening 7 is opened on the side wall of the discharge pipe 6. A sealing mechanism is slidably arranged in the guide strip opening 7. The sealing mechanism includes a sealing plate 15. One end of the sealing plate 15 is slidably inserted into the discharge port 14, and an L-shaped connecting rod 17 is fixedly installed on the lower side of the sealing plate 15. One end of the L-shaped connecting rod 17 slides through the guide strip opening 7 and is fixedly installed with an electric push rod 18.

[0021] One end of the electric push rod 18 is fixedly installed on the outer side wall of the mixing box 1. A sealing side plate 16 is fixedly sleeved on the side wall of the L-shaped connecting rod 17, and the sealing side plate 16 is located on one side of the guide bar opening 7. The sealing side plate 16 can seal the guide bar opening 7, thereby facilitating material discharge through the discharge pipe 6.

[0022] In summary: When mixing carbon fiber composite materials, the raw materials are fed into multiple mixing spaces within the mixing chamber 1 through multiple feed pipes 3. Then, the sealing covers on the feed pipes 3 are closed. Next, the servo motor 5 is activated to rotate the support shaft 12, which in turn rotates the spiral blade 8. The spiral blade 8 utilizes the discharge holes 9 and dispersing teeth on its surface for shearing and mixing. The spiral blade 8 continuously flips the carbon fiber composite material upwards, further agitating the material. Once mixing is complete, the electric push rod 18 on the mixing chamber 1 is activated, causing it to move the L-shaped connecting rod 17 and the sealing plate 15. This allows the sealing plate 15 to exit from the discharge port 14, enabling the mixed material to be discharged from the discharge port 14 and the discharge pipe 6.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
