Embodiment 1
[0032] Such as Figure 1-3The melt impregnation method shown is the equipment for producing long-fiber reinforced thermoplastic resin, including the equipment for decomposing fiber loops into fiber bundles and pretreating them. The fiber bundle independent channel 1 is connected with the fiber pre-fluffing and preheating system 2; Full impregnation and molding equipment, its melt inlet die 6 communicates with the fiber impregnated body 5 through the melt inflow channel 12, and is inclined upward at a certain angle, and the fiber inlet die 4 is used to connect the fiber pre-fluffing and preheating system 2 and the fiber The impregnated body 5 can make the fiber enter the fiber impregnated body 5 horizontally, and the other end of the fiber impregnated body 5 is connected with the forming die 8 .
[0033] In addition, the melt inlet die 6, the fiber inlet die 4, the forming die 8 and the fiber impregnated body 5 are detachable and flexibly combined; the fiber bundle independent ...
