The covering die 2 comprises an inner molten pool core rod 21, an inner and outer laminar flow sleeve 22, an outer core die 23 and a covering die body 24.
The coating die 2 is fixed on one side of the frame 1. The tensioning dragging frame 3 is arranged on the frame 1 in a sliding manner opposite to the coating die 2. Specifically, a longitudinal adjusting screw 11 facing the coating die 2 is arranged on the frame 1, a sliding nut 12 moving longitudinally along with the rotation of the screw is arranged on the longitudinal adjusting screw 11, and the tensioning dragging frame 3 is fixedly arranged on the sliding nut 12 and moves longitudinally along with the sliding nut 12.
The torpedo head shunting shuttle 4 is arranged on the tensioning dragging frame 3 and shunts the multilayer composite woven fiber annular belt 6. The torpedo head shunt shuttle 4 is provided with a plurality of groups of rolling bearing wheels, so that the inner wall of the braided fabric is smoothly guided into the cladding die 2. The surface of the braided fabric guided backwards by the torpedo head shunt shuttle 4 is flat and neat without folds and the braided fabric is not blocked when entering a mould.
Dragging and conveying rollers 5 are coupled on the tensioning and dragging frame 3 and distributed on two sides of the multilayer composite woven fiber annular belt 6, and the multilayer composite woven fiber annular belt 6 is clamped in opposite directions. The device is used for driving the split multilayer composite woven fiber annular belt 6 to enable the split multilayer composite woven fiber annular belt to penetrate through the coating die 2, and then guiding the split multilayer composite woven fiber annular belt to enter other subsequent processes of spraying, drawing, rolling and the like. The dragging and conveying roller 5 is driven by a motor.
