Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced nylon composite material processing equipment, and in particular to glass fiber reinforced nylon composite material extrusion equipment. Background Art

[0002] Glass fiber reinforced nylon is a composite material that is reinforced by adding a certain proportion of glass fiber to nylon resin. Glass fiber reinforced nylon can greatly improve the mechanical properties of nylon, such as tensile strength and flexural strength, so that it can replace metal to manufacture heat-resistant and stress-bearing structural plastic parts in the fields of automobiles, machinery, and chemicals. The processing of glass fiber reinforced nylon composite materials requires the use of extrusion equipment for processing and molding. Glass fiber reinforced nylon composite materials are made by mixing nylon resin pellets and glass fiber pellets in a certain proportion and then putting them into the extruder hopper. The extruder melts, blends, and extrude the pellets to form.

[0003] However, during the processing, since the softening heat temperature of glass fiber is much higher than the softening heat temperature required by nylon resin, when the extrusion temperature of the extruder is too low, the fluidity of the glass fiber will be poor and it will not be easy to be crushed and dispersed. When the temperature is too high, the nylon resin will soften excessively, the viscosity will be high, and the shear effect will be poor, resulting in a decrease in the dispersion of the glass fiber when mixed with the glass fiber. Moreover, since the weight of glass fiber pellets is usually heavier, after the mixed pellets are put into the extruder hopper, the glass fiber pellets are more likely to settle downwards, which can easily lead to uneven mixing of the pellets and affect the quality of the finished product.
