By changing the connection method between the threaded rod 101 and the extension rod 16, the winding and unwinding device 9 can be installed or disassembled.

[0030] Working principle: In use, first, the take-up and unwinder 9 is installed on the outer wall of the threaded rod 101. Then, the threaded rod 101 passes through the front extension rod 16 and exits from the rear extension rod 16. At this time, the take-up and unwinder 9 can be installed on the extension rod 16 through the connecting assembly 10. The roll 902 is laid on the curved rod 14. Turn on the power of the parallel three-cylinder pressure multiplier cylinder 1. After the parallel three-cylinder pressure multiplier cylinder 1 is turned on, it drives the upper four-point balance bracket 3 to move towards the roll 902 through the connection of the lifting rod 2. The guide rod 4 moves inside the upper four-point balance bracket 3. At this time, the hot-tip device 15 can achieve heat sealing of the filling port. Finally, when it is necessary to disassemble the hot-tip device 15, the fastening bolt 7 can be taken out from the inside of the sleeve rod 19. At this time, the fastening bolt 7 can separate the mounting plate 8 and the lower four-point balance bracket 6, and the hot-tip device 15 can be disassembled.
