[0040] The working principle of the above embodiment is:

[0041] (1) When winding the plastic film around the outer side of the paper roller body 2, firstly place the two ends of the support roller 3 on the two support frames 4 respectively, and insert the second positioning rod 110 into the left support roller 3, then start the cylinder 105, and the cylinder 105 drives the movable box 106 to move slowly to the left through the output shaft, and the movable box 106 drives the rotating plate 108 and the first positioning rod 109 to move slowly to the left through the motor 107. During the movement of the first positioning rod 109, the support roller 3 is rotated so that the first positioning groove on the right support roller 3 is aligned with the first positioning rod 109, until the first positioning rod 109 is inserted into the first positioning groove, and then the cylinder 105 is closed, and the cylinder 105 is closed. After the plastic film is attached to the paper roller body 2, the motor 107 can be started. The motor 107 drives the rotating plate 108 to rotate through the output shaft. The rotating plate 108 drives the supporting roller 3 to rotate through the first positioning rod 109, and drives the paper roller body 2 to rotate together through the supporting roller 3, so that the paper roller body 2 can complete the work of winding the plastic film during the rotation process. The driving mechanism 1 drives the supporting roller 3 to rotate automatically through the cooperation of the limit block 101, the cylinder 105, the movable box 106, the motor 107, the rotating plate 108 and the first positioning rod 109, thereby driving the paper roller body 2 to rotate continuously in one direction, avoiding the reversal phenomenon caused by manual operation of the staff.

[0042] (2) After the first positioning rod 109 is inserted into the first positioning groove, the electric push rod 605 is started. The electric push rod 605 drives the mounting frame 607 to move upward through the output shaft, and drives the plastic film to move upward through the mounting frame 607 until the plastic film is attached to the paper roll body 2. Then, the beginning of the plastic film for winding is attached to the position of the paper roll body 2 close to the plastic film. Then, the motor 107 and the drive motor 604 are started. The drive motor 604 drives the threaded rod 602 to rotate slowly through the output shaft. The two threaded sleeves 601 move to the left or right as the threaded rod 602 rotates, and The supporting frame 4 is driven to move together through the connecting block 603, thereby driving the paper roller body 2 to move together. The paper roller body 2 rotates while reciprocating left and right, and drives the attached plastic film to rotate during the rotation, so that the plastic film is wound around the surface of the paper roller body 2 to form a protective layer, and the protective layer is formed comprehensively and multi-layered during the continuous rotation and left and right movement. The packaging mechanism 6 makes the plastic film as close to the paper roller body 2 as possible through the cooperation of the electric push rod 605, the limit plate 606 and the mounting frame 607, so as to facilitate the paper roller body 2 to wind the plastic film to form a protective layer during the rotation process.
