The two transmission wheels 53 on one side are connected to the corresponding transmission belt 54. The movement of the first rack 5 drives the first gear 51 to rotate. The rotation of the first gear 51 drives the first rotating shaft 52 to rotate. The rotation of the first rotating shaft 52 drives the transmission wheel 53 on one side to rotate. The transmission wheel 53 on one side drives the transmission wheel 53 on the other side to rotate through the transmission belt 54. The rotation of the transmission wheel 53 on the other side drives the second rotating shaft 58 to rotate.

[0024] This invention can be equipped with a liquid sensor for detecting the impregnation material. The liquid sensor monitors the impregnation material in the impregnation tank 11 in real time. When there is too much or too little impregnation material, the liquid sensor sends a command to the first servo electric cylinder 33 through the controller, and the control of the liquid in the impregnation tank 11 is completed through component linkage. The aforementioned controller and liquid sensor structures are mature technologies in the prior art and are not shown in the figure, so they will not be described in detail here. During use, carbon fiber material is placed in the impregnation tank 11, and the carbon fiber material is placed at the bottom of the cutting blade 41 after passing through the bottom of the rotating roller 32. During the impregnation of carbon fiber, the first servo electric cylinder 33 adjusts the moving frame according to the impregnation situation. When adjusting the height of the frame 31 and the rotating roller 32, the first servo electric cylinder 33 drives the moving frame 31 and the rotating roller 32 to move via the piston rod. The rotating roller 32 presses the carbon fiber material into the impregnation tank 11 for impregnation. When the piston rod moves up and down, it drives the moving rod 34 to move. The moving rod 34 drives the first rack 5 to move. The moving rack 5 drives the first gear 51 to rotate. The rotation of the first gear 51 drives the first rotating shaft 52 to rotate. The rotation of the first rotating shaft 52 drives the transmission wheel 53 on one side to rotate. The transmission wheel 53 on one side drives the transmission wheel 53 on the other side to rotate via the transmission belt 54. The rotation of the transmission wheel 53 on the other side drives the second rotating shaft 58. The rotation of the second rotating shaft 58 drives the second gear 57 to rotate, which in turn drives the third rack 56 and the second rack 55 to move. The second rack 55 drives the first connecting rod 14 to move via the first crossbar 15. The movement of the first connecting rod 14 causes the first spherical seal 13 to open and close the discharge hole at the bottom of the hopper 12. The third rack 56 drives the second connecting rod 23 to move via the second crossbar 24. The second connecting rod 23 drives the second spherical seal 22 to move, which in turn opens and closes the discharge hole at the bottom of the storage tank 21. By controlling the discharge holes at the bottom of the hopper 12 and the storage tank 21, the material can be transported through the hopper 12. Through the above operations, the amount of impregnating material in the impregnation tank 11 can be controlled. After the carbon fiber material is impregnated, it is moved to the top of one side of the impregnation device body 1, and the second servo electric cylinder 42 is opened. The second servo electric cylinder 42 drives the cutting blade 41 to move through the piston rod, and the cutting blade 41 cuts the carbon fiber material. In this utility model, while adjusting the roller 32 to press the carbon fiber material, the device can simultaneously open and close the discharge hole of the storage tank 21 and the hopper trough 12. The liquid level adjustment of the impregnating material in the impregnation tank 11 can be completed without manual operation. The dynamic adjustment of the impregnating material avoids insufficient or excessive impregnation, reduces impregnation waste, and greatly reduces production costs.
