[0028] Working principle and advantages of the present invention: When the aircraft composite fiber cloth dipping device is used, the working process is as follows:

[0029] like Figure 1 and Figure 4 As shown, the lifting cover plate 2 is lifted by starting the hydraulic cylinder 3, and then the composite fiber cloth to be dipped in glue is rolled onto the winding roller 8, one end of the composite fiber cloth is pulled out to pass around a portion of the straight rod, and then passes through the tensioning roller group 23, and finally fixed on the winding roller 24. After the composite fiber cloth is installed, the hydraulic cylinder 3 is started again to drive the lifting cover plate 2 to fall and seal on the upper port of the dipping tank 1. At this time, the composite fiber cloth is completely immersed in the glue liquid inside the dipping tank 1, and the sealing ring 4 plays a sealing role.

[0030] After the above operation is completed, the motor 5 is started to work, so that the motor 5 drives the shaft rod 1 7 to rotate, so that the shaft rod 1 7 drives the winding roller 1 8 and the gear 1 12 to rotate synchronously, and the gear 1 12 rotates while driving the shaft rod 3 9 to rotate through the gear 2 13, so that the shaft rod 3 9 synchronously drives the pulley disc 1 11 to rotate, and then the pulley disc 1 11 drives the pulley disc 2 15 to rotate synchronously through the belt 16, so that the pulley disc 2 15 synchronously drives the shaft rod 2 14 and the winding roller 2 24 at its lower end to rotate synchronously , and the winding roller 1 8 and the winding roller 2 24 make a rotational motion in opposite directions, so that when the winding roller 1 8 unwinds the composite fiber cloth roll, the winding roller 2 24 winds the composite fiber cloth, so that the composite fiber cloth can be fully soaked with glue and will not loosen. When the winding roller 1 8 completely unwinds the composite fiber cloth roll, the motor 5 is started to reverse, so that the winding roller 2 24 unwinds and the winding roller 1 8 winds, and so on and so forth, multiple winding and unwinding and dipping can be performed to improve the dipping effect.

[0031] As described above, the rotation of the shaft rod 3 9 drives the turntable 10 and the straight rods 22 thereon to rotate, so that the straight rods 22 roll the composite fiber cloth in the winding process, thereby helping to discharge the bubbles in the composite fiber cloth and allowing the glue to penetrate the pores of the composite fiber cloth. In addition, since the rotation axis of the gear 12 is not at the center of the circle, Figure 2 and Figure 3As shown, the gear 12 is equivalent to a cam, so that when it rotates and under the action of the elastic pull rope 31, the lever 18 swings back and forth, so that the turntable 10 drives each straight rod 22 to rotate and reciprocates in an arc trajectory, so that the straight rod 22 has a stirring effect on the glue, so that the bubbles in the glue are quickly discharged upward, which helps to improve the glue impregnation effect on the composite fiber cloth.

[0032] During the swinging process of the lever 18, the lever 2 19 is synchronously driven to swing, so that the lever 2 19 drives the piston plate 26 to move back and forth in the pump barrel 25 through the pin rod 32 and the push-pull rod 27, so that the piston plate 26 alternately applies suction force and compression force to the space on both sides thereof. When the suction force is applied to the space, since the conduction direction of the one-way valve 1 28 points to the inside of the pump barrel 25, and the conduction direction of the one-way valve 29 points to the exhaust pipe 30, the suction force sucks the air in the dipping pool 1 into the space through the one-way valve 1 28. When the compression force is generated in the space, the compression force discharges the air in the space through the one-way valve 29 and the exhaust pipe 30 to the outside of the dipping pool 1, thereby reducing the spatial pressure above the glue liquid in the dipping pool 1, which helps to discharge the air in the glue liquid, so that the glue liquid can fully penetrate into the pores of the composite fiber cloth, thereby improving the dipping effect.

[0033] As described above, in the process of winding the composite fiber cloth, the diameters of the winding roller 1 8 and the winding roller 2 24 change differently, and the force of each straight rod 22 on the composite fiber cloth is different during the swinging of the lever 18. Therefore, the force of the composite fiber cloth on the tensioning roller group 23 changes continuously, so that the elastic action of the spring 36 can be used to adjust the position of the tensioning roller group 23 in real time, that is, the shaft frame 34 slides on the slide rod 37 to adjust the position, thereby ensuring that the composite fiber cloth is always in a tensioned state and will not loosen, so as to keep the composite fiber cloth impregnation process stable, and the composite fiber cloth is rolled by the tensioning roller group 23 when passing between the tensioning roller groups 23, thereby further expelling the air in the pores of the composite fiber cloth and improving the impregnation effect.

[0034] After the dipping is completed, the pressure relief valve 21 is opened to balance the pressure inside and outside the dipping pool 1, the hydraulic cylinder 3 is started to raise the lifting cover plate 2, the motor 5 works for a suitable time to discharge most of the excess glue on the composite fiber cloth, the motor 5 is turned off, and the composite fiber cloth roll is removed. The operation is simple and convenient.
