The dipping die 1 is used for dipping the fiber bundle 4, various existing dipping device dies can be adopted, and as a preferred technical scheme, an outlet channel 10 is arranged at the end part of the dipping die 1, the outlet channel 10 comprises a circular table section and a cylindrical section, a central positioning cylinder 9 is arranged in the circular table section, the central positioning cylinder 9 is cylindrical, and the central positioning cylinder 9, the circular table section and the cylindrical section are coaxially arranged. The central positioning cylinder 9 can be used for primarily positioning the fiber bundle 4, and in the working process, the fiber bundle 4 penetrates through the central positioning cylinder 9 and then is discharged from the cylindrical section of the outlet channel 10, so that the coaxiality of the fiber bundle 4 and the outlet channel 10 is ensured, and the fiber bundle 4 is prevented from greatly deviating in a fiber bundle traction channel.

The traction mechanism 2 is used for drawing out the impregnated fiber bundle 4, and the structure of the traction mechanism 2 can be realized by adopting the prior art. The traction mechanism 2 is arranged on the position adjusting mechanism, and the position of the traction mechanism 2 can be adjusted through the position adjusting mechanism.

The horizontal deviation detecting mechanism 5 can continuously detect the horizontal position of the fiber bundle 4 in real time and transmit a signal to the controller 3 according to the detection result, and the vertical deviation detecting mechanism 6 can continuously detect the vertical position of the fiber bundle 4 in real time and transmit a signal to the controller 3 according to the detection result. When the fiber bundle 4 deviates left and right, the horizontal deviation detection mechanism 5 can transmit the detection result to the controller 3, the controller 3 controls the position adjusting mechanism to operate, and the position adjusting mechanism drives the traction mechanism 2 to move horizontally to change the deviation state of the fiber bundle 4. When the fiber bundle 4 is vertically deviated, the vertical deviation detection mechanism 6 can transmit a detection result to the controller 3, the controller 3 controls the position adjusting mechanism to operate, and the position adjusting mechanism drives the traction mechanism 2 to move up and down to change the deviation state of the fiber bundle 4. The controller 3 may adopt an existing control device such as a PLC controller, a computer, or the like.

The specific working process of the special prepreg shaping device for printing the composite material is as follows: the fiber bundle 4 is drawn out by the drawing mechanism 2 after passing through the dipping die 1, the horizontal deviation detection mechanism 5 detects the horizontal position of the fiber bundle 4 in real time, when the fiber bundle 4 deviates in the horizontal direction, the horizontal deviation detection mechanism 5 transmits a horizontal adjustment signal to the controller 3, the controller 3 controls the position adjusting mechanism to operate to drive the drawing mechanism 2 to move horizontally, and the moving direction is opposite to the deviation direction of the fiber bundle 4 until the horizontal adjustment signal is terminated. When the fiber bundle 4 is adjusted again, the horizontal deviation detection mechanism 5 detects that the position of the fiber bundle 4 is returned to normal, and stops transmitting the horizontal adjustment signal to the controller 3, so that after the horizontal adjustment signal is terminated, the traction mechanism 2 is at a proper horizontal position, and the adjustment can be stopped.

Meanwhile, the vertical offset detection mechanism 6 detects the vertical position of the fiber bundle 4 in real time, when the fiber bundle 4 is offset in the vertical direction, the vertical offset detection mechanism 6 transmits a vertical adjustment signal to the controller 3, the controller 3 controls the position adjusting mechanism to operate, the traction mechanism 2 is driven to vertically move, and the moving direction is opposite to the offset direction of the fiber bundle 4 until the vertical adjustment signal is terminated. When the fiber bundle 4 is straightened again, the vertical deviation detection mechanism 6 detects that the position of the fiber bundle 4 is normal, and stops transmitting the vertical adjustment signal to the controller 3, so that after the vertical adjustment signal is terminated, the traction mechanism 2 is in the proper vertical position, and the adjustment can be stopped.
