Abstract

This utility model discloses a heat-sealing furnace for laminated glass production, relating to the field of tempered glass processing technology. The heat-sealing furnace includes a heat-sealing furnace and an elastic pressing device. The elastic pressing device includes hydraulic cylinders, pressing plates, a frame, heating wires, partition plates, spring rods A, and placement plates A. Multiple hydraulic cylinders are fixedly connected to the top of the heat-sealing furnace. Multiple pressing plates are slidably connected inside the heat-sealing furnace. The frame is fixedly connected to the pressing plates. The heating wires are fixedly connected inside the pressing plates. Multiple partition plates are equidistantly fixedly connected inside the heat-sealing furnace. The number of placement plates A is the same as the number of spring rods A, and they are all fixedly connected to the top of the corresponding partition plates. The combination of the elastic pressing device and the heating wires improves the flatness and quality of the finished glass product. The elastic support design of the spring rods prevents deformation of the glass due to rigid compression during the heat-sealing process.
