[0019] like Figure 23, it also includes an expansion mechanism 16, the expansion mechanism 16 includes a ring 17 sleeved on both ends of the winding roller 24, a telescopic rod 18 arranged on the outside of the ring 17, the upper end of the telescopic rod 18 is movably provided with a sleeve rod 9, a part of the telescopic rod 18 is movably engaged in the interior of the sleeve rod 9, the upper end of the sleeve rod 9 is provided with an expansion ring 10, the upper end of the telescopic rod 18 is provided with an electric push rod 19, and the output end of the electric push rod 19 is connected to the inner upper end of the sleeve rod 9.

[0020] When the winding roller 24 is winding the packaging film, the sleeve rod 9 can be pushed to move by the electric push rod 19, and the sleeve rod 9 drives the expansion ring 10 to move, so that the distance between the expansion ring 10 and the telescopic rod 18 becomes larger, so that the winding roller 24 can wind more when winding the packaging film, and at the same time prevent the two ends of the packaging film from protruding from the two ends of the winding roller 24, which is more convenient for the subsequent storage and use of the packaging film.

[0021] like Figure 4 5, it also includes a disassembly mechanism 11, a disassembly mechanism 11 is arranged between the fixed shaft 3 and the quick-release shaft 7, the disassembly mechanism 11 includes a limit block 12 and a groove 13, the outer wall of the quick-release shaft 7 is integrally formed with the limit block 12 and the inner wall of the fixed shaft 3 is provided with a groove 13; the outer wall of the quick-release shaft 7 is provided with a limit block 12, when the quick-release shaft 7 and the fixed shaft 3 are docked, the limit block 12 on the outer wall of the quick-release shaft 7 is aligned with the groove 13 on the inner wall of the fixed shaft 3, after the docking is completed, the limit block 12 is just inserted into the groove 13, through the cooperation of the groove 13 and the limit block 12, a connection locking effect is played, so that when the transmission shaft 1 rotates under the action of the motor 15, it can drive the carbon fiber roller 4 to rotate synchronously.

[0022] The end of the movable shaft 6 away from the quick-release shaft 7 is fixedly connected to a central shaft 8 that penetrates the spring 5 and extends to the inside of the carbon fiber roller 4.
