[0028] One specific application of the embodiment is:

[0029] In use, the CPP film is conveyed in the box 1, and the transmission roller 14 is used to assist the CPP film conveying. The hydraulic cylinder 111 is started to drive the lifting frame 13 to move upward or downward, and the tension adjusting roller 131 moves together.

The opening 4 can make the adjusting frame 121 turn over smoothly, avoiding the shielding condition. The deviation correcting roller 122 pushes the CPP film forward to correct it. Conversely, when the CPP film deviates to the front, the motor 251 drives the rotating disc 252 to rotate clockwise, so that the fixed shaft 253 moves downward. At this time, the rear of the adjusting frame 121 drives the deviation correcting roller 122 to move downward through the gravity, so as to push the CPP film to the rear to correct it. Through the height adjustment of the deviation correcting roller 122, the CPP film can be corrected smoothly, so that it is more stable during conveying, so as to keep the edges neat and improve the product quality.
