[0002] The existing non-metal photovoltaic frame is generally formed by pultrusion of glass fiber and resin. Multiple glass fiber yarns are introduced from a glass fiber yarn rack into a mold for pultrusion. Before entering the mold, in order to reduce the moisture in the glass fiber and avoid bubbles in the formed photovoltaic frame, the glass fiber needs to be dried before entering the mold.

[0003] In the existing production process, the glass fiber yarn is first dried and stored, and then the dried glass fiber is introduced into the mold before production. This process has certain requirements for the storage environment of the glass fiber. If it is not stored properly, moisture will still remain in the glass fiber, resulting in bubbles in the produced photovoltaic frame. Therefore, in order to reduce the impact of the external storage environment on the glass fiber, the utility model designs a hot air drying device for photovoltaic frame pultrusion equipment. The drying device can dry multiple glass fiber yarns at the same time, meeting the drying requirements of the glass fiber yarn, and the drying device is placed in front of the pultrusion mold to reduce the moisture in the glass fiber before the pultrusion process.
