Combined type sealing screw rod structure of universal rubber post-treatment equipment

The utility model discloses a universal type rubber post-treatment equipment combined type sealing screw rod structure which is characterized in that a screw rod mandrel is divided into a welding section and a combination section, a screw sheet is welded on the welding section, a screw sleeve with the screw sheet is sleeved on the combination section, a sealing ring is arranged at each connectingend of the screw sleeve, and the screw sleeve is fixed and clamped by a screw rod head. According to the screw rod structure, two modes of combining the welding screw sheet and the screw sleeve are simultaneously used, so that the rigidity of the screw rod is greatly improved, and shaft breakage is effectively prevented; the effect of reuse can be achieved by replacing the thread sleeve, and the maintenance cost is reduced; the sealing performance is good, water is effectively prevented from entering the gap to cause corrosion of the mandrel, and therefore the durability of the screw is improved. 本实用新型公开了一种通用型橡胶后处理设备组
