Example Embodiment
[0026] figure 1 Shown is an embodiment of the glass fiber reinforced nylon 66 heat insulation strip production device of the present invention, including a feeding system, an extruder 1, a pressure control system 2, a die 3, a shaping die 4, a heating control system 5, and a cooling system 6. And traction system 7.
[0027] Such as figure 1 As shown, the feeding system includes a feeding pipe 8 and a hopper, and each feeding pipe 8 conveys a single component of the raw material to the hopper. There are two hoppers, a main hopper 9 and a side feeding hopper 9'; Give the extruder 1. Extruder 1 is a twin screw extruder.
[0028] The screw of the twin-screw extruder 1 is made of bi-alloy nitrided steel, and the length-to-diameter ratio of the screw is 36-44 to fully plasticize the nylon resin, eliminate glass fiber exposure, and make the temperature distribution of the material more reasonable.
[0029] The shaping mold 4 and the die 3 adopt a double-convex platform 10 structure in t...
