Pressurizing pre-impregnating die head special for fiber reinforced plastic sheet machine

A pressurizing pre-impregnating die head special for a fiber reinforced plastic sheet machine, comprising a die head body, wherein

• at least one group of fiber channel which is arranged in a longitudinal hole-through manner is formed in a middle part of the die head body, and a fiber yarn is conveyed in the fiber channel;
• and
• the die head body comprises a feeding port and discharging ports, which communicate with each other, the discharging ports are located in outer sides of the fiber channel, and thermoplastic base materials in a molten state are paved on two sides of the fiber yarn respectively;
• wherein a heat flow channel for conveying the thermoplastic base materials is formed in the die head body, and one end of the heat flow channel communicates with the feeding port and the other end of the heat flow channel communicates with the discharging ports in a one-to-one corresponding manner through flow dividing channels;
• wherein a material equalizing chamber is arranged at one end, communicating with each discharging port, of each of the flow dividing channels, and one end of the material equalizing chamber communicates with each of the flow dividing channels and the other end of the material equalizing chamber communicates with each of the discharging ports;
• the material equalizing chamber has a triangular structure;
• the flow dividing channel communicates with one vertex angle position of the triangular structure, the discharging port occupies one side opposite to the vertex angle where the flow dividing channel is located;
• wherein an opening of each of the discharging ports has a thin and long structure, the opening of each of the discharging ports has a flat structure, the material equalizing chamber communicating with the feeding port has a flat structure, two sides of the material equalizing chamber are inclined surfaces, and a thickness of the material equalizing chamber is gradually reduced from the flow dividing channels to the discharging ports.
