Description
Heating and impregnation device for continuous fiber reinforced thermoplastic resin matrix composite filaments
The present invention belongs to the field of continuous fiber reinforced thermoplastic resin matrix composites, and specifically relates to a heating and impregnation device for continuous fiber reinforced thermoplastic resin matrix composite filaments.
As a type of novel and high-performance materials, continuous fiber resin matrix composites are currently widely used in the fields of aerospace, wind power generation, rail transit, etc. and have broad application prospects in the civilian field. In the context of environmental protection needs, high-performance continuous fiber reinforced thermoplastic resin matrix composites have become a focus of current research due to their recyclability and environment friendliness.
At present, continuous fiber bundles are first pre-dispensed by pre-tensioning rollers during processing, upper and lower surfaces of continuous fibers are pre-heated by an infrared radiation device, the pre-heated continuous fibers expand a width under the action of a gas-assisted swing device and then enter a filament infiltration mold, and a resin matrix infiltrates the fiber bundles under the action of a wavy flow channel. However, there is no tension control in the flow channel, so filament breakage or uneven infiltration is prone to occur, and product quality control is poor.
To solve the above problems, the present invention discloses a heating and impregnation device for continuous fiber reinforced thermoplastic resin matrix composite filaments, which improves filament spreading efficiency, where fibers are pre-heated by hot pressing of heating rollers to achieve full impregnation and improve filament impregnation quality.
A heating and impregnation device for continuous fiber reinforced thermoplastic resin matrix composite filaments comprises a filament feeding roller, a heating box, and an impregnation box, where the heating box comprises a plurality of heating rollers arranged sequentially; an inlet guide roller and an outlet guide roller are arranged at two ends in the impregnation box respectively; a filament guide nozzle is arranged at a discharge end of the impregnation box; first channel direction rods and second channel direction rods are sequentially arranged at intervals in the impregnation box; an impregnation roller is arranged at a bottom of each of the first channel direction rods and the second channel direction rods; and a length of the first channel direction rod is less than that of the second channel direction rod.
Further, the length of the first channel direction rod is half of that of the second channel direction rod.
Further, an insulation layer is arranged in an inner wall interlayer of the heating box.
Further, a bottom of the impregnation box is arranged in a heating hood, which provides heat for the impregnation box to ensure impregnation fluidity of the impregnation box.
Further, a cover plate is movably arranged at a top of the impregnation box; and the cover plate is connected to a support plate through a cylinder. The cylinder drives the cover plate upwards, and the top of the impregnation box can be opened for later maintenance and repair by workers.
Further, the impregnation box is provided with a plurality of temperature sensors to know internal temperature of the impregnation box in a timely manner for easy regulation.
Filaments are fed into the heating box by the filament feeding roller, and the filaments pass through the heating rollers in the heating box. Fibers are pre-heated by hot pressing of the heating rollers arranged sequentially in the heating box, while a sizing agent is removed from surfaces thereof to enhance an impregnation effect.
The pre-heated filaments are fed into a flow channel of the impregnation box by the inlet guide roller. The low first channel direction rods and the high second channel direction rods arranged in the flow channel ensure stability of the filaments traveling over the impregnation rollers, provide stable tension, and ensure full impregnation. Finally, the filaments are fed into the filament guide nozzle by the outlet guide roller and discharged.
Beneficial effects of the present invention are as follows: a size is removed from fiber bundles and the fiber bundles are pre-heated by the heating rollers, and continuous fibers are fully impregnated in the impregnation box, thereby ensuring that the continuous fibers are fully melted and impregnated, providing stable tension for the impregnation process, and improving filament impregnation quality.
