Activating the hydraulic rod 9 moves the moving plate 8 to the right, causing it to also press against one end of the sleeve 5, moving it to the right until the shaft groove 7 on the moving plate 8 engages with the shaft 6 mounted on one end of the film winding roller 4. After the staff adjusts the position of the sleeve 5 on the film winding roller 4, they activate the double-rod hydraulic cylinder 12 installed on the film winding roller 4. This causes the two sets of limiting arc plates 13 to move outward away from the outer wall of the film winding roller 4. The outer walls of the two sets of limiting arc plates 13 abut against the inner ring wall of the sleeve 5, thus fixing the sleeve 5 on the film winding roller 4. As the motor 3 starts, the film winding roller 4 drives the sleeve 5 to perform film winding. After film winding is completed, the double-rod hydraulic cylinder 12 retracts to release the fixation. Then, the hydraulic rod 9 is activated to retract, causing the moving plate 8 to move to the left. In conjunction with the connecting plate 10, the unloading ring 11 moves to the left, thereby removing the sleeve 5 from one end of the film winding roller 4. When installing and unloading the sleeve on the film winding roller 4, it is not necessary to remove and reinstall the film winding roller 4 to install and fix the sleeve, saving a lot of manpower and time and improving film winding efficiency.

[0027] The implementation principle of a film roll for printing composite environmentally friendly packaging bags in this application embodiment is as follows: A sleeve 5 is fitted onto one end of the film roll 4. The hydraulic rod 9 is activated, causing the moving plate 8 to move to the right. The moving plate 8 also abuts against one end of the sleeve 5, causing it to move to the right. The moving plate 8 moves to the right until the shaft groove 7 on it engages with the shaft rod 6 installed at one end of the film roll 4. At this point, the operator adjusts the position of the sleeve 5 on the film roll 4 and then activates the double-rod hydraulic cylinder 12 installed on the film roll 4. This causes the two sets of limiting arc plates 13 to move outward away from the outer wall of the film roll 4. The outer wall of the arc plate 13 abuts against the inner ring wall of the sleeve 5, thereby fixing the sleeve 5 onto the film winding roller 4. As the motor 3 starts, the film winding roller 4 drives the sleeve 5 to perform film winding. After film winding is completed, the double-rod hydraulic cylinder 12 retracts to release the fixation. Then, the hydraulic rod 9 is started to retract, causing the moving plate 8 to move to the left. In conjunction with the connecting plate 10, the unloading ring 11 moves to the left, thereby removing the sleeve 5 from one end of the film winding roller 4. When installing the sleeve and unloading the film winding roller 4, it is not necessary to remove and reinstall the film winding roller 4 to install and fix the sleeve, saving a lot of manpower and time and improving film winding efficiency.
