Abstract

The invention belongs to the field of thermal insulation pipe manufacturing machines, and especially relates to an outer sleeve seal head, comprising an upper baffle and a lower baffle. The upper baffle and the lower baffle are connected through a connecting rod. The rear sides of the upper baffle and the lower baffle are respectively adhered to a rigid foam layer. The diameter of the rigid foam layer is larger than the diameter of the upper baffle and the lower baffle. The middle parts of the upper baffle and the lower baffle are provided with pull rods. The front end of the pull rod is provided with a rope fixing hole. The seal head is simple in structure. Through two connected baffles and adhering a rigid foam layer on the baffle, since the diameter of the rigid foam layer is larger than the diameter of the baffle, when the baffles moves towards a protective pipe which is being molded, the baffle can tightly abut against the inner wall of the protective pipe. When a part of the protective pipe is formed, the seal air block moves forward for a section of distance. The middle part of the protective pipe is not needed pressing, the two baffles and the rigid foam can block. Cutting the pipe again is not needed. The outer sleeve seal head saves materials and time, and is high in working efficiency.
