Air curtain type heat-insulation and heat-equalizing structure for fiber pipeline winding forming machine

Abstract

The invention relates to an air curtain type heat-insulation and heat-equalizing structure for a fiber pipeline winding forming machine. The air curtain type heat-insulation and heat-equalizing structure for the fiber pipeline winding forming machine comprises a long-strip-shaped heating furnace body, wherein the heating furnace body is arranged on the peripheral side of a die shaft of the fiber pipeline winding forming machine; a plurality of heating plates arranged in the length direction of the heating furnace body are arranged inside the heating furnace body; a furnace opening is formed inthe top of the heating furnace body, and a furnace cover is suspended above the furnace opening; openings are formed between the two sides of the furnace cover and the two sides of the heating furnace body; and the two sides of the furnace cover are each provided with an exhaust fan with an air outlet facing downwards in the length direction of the furnace cover, and the two exhaust fans correspondingly form air curtains which are longitudinally blown into the heating furnace body. The air curtain type heat-insulation and heat-equalizing structure for the fiber pipeline winding forming machine is reasonable in design, simple in structure, and good in heat-insulation and heat-equalizing effect, and the problems that deformation, cracking and untight bonding due to uneven heating of a fiberpipeline are effectively solved.

Description

technical field [0001] The invention relates to the technical field of fiber pipe winding processing equipment, in particular to an air curtain heat-insulating and uniform structure of a fiber pipe winding forming machine. Background technique [0002] Most of the existing composite pipes are processed and formed by winding multi-layer sheets on the outer peripheral surface of the mold shaft by a winding machine, that is, sheets such as continuous fibers impregnated with resin glue, cloth tapes, prepreg yarns, etc. After coiling and preheating, it is wound on the mold shaft according to certain rules, and then undergoes processes such as heating and melting, rolling, cooling and solidification, and demoulding to obtain finished products. [0003] The existing fiber pipe winding molding machine includes a mold shaft that is placed horizontally on the frame and rotates along its axial direction, and one side of the mold shaft is provided with a feeding guide device for sending...

AI Technical Summary

Problems solved by technology

Although the heating method of the heating mantle can improve the winding process in the winding process of the sheet, it is easy to cause deformation of the pipeline due to uneven heating due to uneven heating of the composite sheet in the winding process. Problems such as cracking and poor bonding
