A vertical silicone rubber extrusion and sulfidization production line is formed by a vertical silicone rubber extruder and a vertical sulfidization drying tunnel; the silicone rubber extruder is placed on a hathpace, equipped with a right-angle machine head, and corresponding to the vertical sulfidization drying tunnel, so as to realize extrusion from the top down; a heating area is arranged on the inner wall of the vertical sulfidization drying tunnel; and a ceramic infrared radiation device is mounted in the heating area. The utility model has the beneficial effects that firstly, the occupancy area is small and is usually about only two square meters; secondly, silicone rubber products can not be deformed due to the vertical extrusion and sulfidization manner; thirdly, compared with thehorizontal drying tunnel, 50 to 80 percent of practical power consumption of the drying tunnel is reduced; and fourthly, the production operation for controlling the size of silicone rubber productsis simpler than that in the horizontal manner.
