The invention discloses a seamless winding large-diameter high-temperature resistant PPH head sealing mechanism and its application method, including a base for supporting the mechanism and an operation console arranged beside the base. A sliding platform is installed on the base, a rotating bracket is arranged on the sliding platform, and a rotating motor for driving the bracket is installed between the platform and the bracket. A main shaft is mounted on the top of the rotating bracket with molds installed at both left and right ends. Head sealing devices made of PPH materials are arranged in front of the two molds respectively. The control terminals of the sliding platform, rotating motor and head sealing devices are electrically connected to the operation console. The invention overcomes the defects of low head sealing quality and low efficiency in the prior art, and has the advantages of low vibration, high stability and high working efficiency during operation.
