Infrared rapid preheating tool for laminating air short-cut carbon fiber thermoplastic sheet

Abstract

This utility model discloses an infrared rapid preheating fixture for laminating aerospace chopped carbon fiber thermoplastic sheets, relating to the field of chopped carbon fiber thermoplastic sheet processing technology. The utility model includes a frame with two symmetrically distributed frames. A preheating mechanism is located on the upper part of the two frames for preheating the aerospace chopped carbon fiber thermoplastic sheets. The preheating mechanism includes a flipping assembly comprising two conveyor belts located on the upper part of the frame. An infrared heating device is fixedly installed at the top center of the two frames. When the drive motor drives the drive disk to rotate, the drive block cooperates with the drive groove of the rotating disk, driving the rotating shaft and the rotating disk to rotate intermittently. This causes the aerospace chopped carbon fiber thermoplastic sheet to rotate 180 degrees with the rotating disk in the groove, so that the original bottom surface faces upwards. This allows for rapid and uniform infrared radiation heating of both sides of the sheet, greatly improving the comprehensiveness and efficiency of preheating and ensuring more uniform heating of the sheet.
