Further, a gap is formed between the limiting block and the adjusting plate.

Further, the first rotating shaft and the second rotating shaft are respectively provided with nuts, and the nuts are respectively in threaded connection with the first rotating shaft and the second rotating shaft.

Further, a fastening block is fixedly arranged on the side face of the fixing plate, and an output roller is arranged on the fastening block.

Further, two ends of the output roller penetrate into the fastening blocks and are in rotary connection with the fastening blocks.

Compared with the prior art, the utility model has the beneficial effects that: according to the rolling mechanism for the packaging film, the upper rolling assembly and the lower rolling assembly are arranged to form the packaging film on the strip-shaped plastic raw material pressing roller, the motor can be used for driving the first rotating shaft, the second rotating shaft, the upper pressing cylinder and the lower pressing cylinder to rotate in a rotating mode, so that the pressing roller is carried out, the placing table is arranged to enable the plastic raw material to be kept in a straight state and enter the upper rolling assembly and the lower rolling assembly for rolling, and the phenomena of raw material deviation and the like in the rolling process can be prevented.
