The invention discloses an automatic production line for double-type corner protectors, comprising a screw extruder, a forming mold, a shaping mold, a water tank, a punching and cutting device and a winding device. The screw extruder, forming mold, shaping mold and water tank are sequentially fixed on a frame. Materials enter the screw extruder through a feeding port arranged on the screw extruder, and the screw extruder conveys the materials to the forming mold. After being heated by the forming mold, the materials are extruded from the forming mold, then enter the shaping mold for shaping, cooled by the water tank, punched and cut by the punching and cutting device, and finally wound on the winding device. The invention has the advantages that stepping feeding can be realized by the rotation of a stamping part pulley, meeting the needs of automatic production. One production line can produce two corner protectors at the same time, doubling the work efficiency.
