[0003] In the comparative document, a winding device for a film blowing machine and a film blowing machine, during use, use a pressure roller to press the film roll under the action of the compression spring force, and then use an electric telescopic rod and a pressure sensor to enable the pressure roller to adjust the height according to the diameter of the film roll. However, during such use, the device fails to link the winding operation of the film roll and the height adjustment of the pressure roller, but instead additionally adjusts the height of the pressure roller through an electric telescopic rod and a pressure sensor, which increases the use cost and energy consumption of the device and reduces the practicability of the device.
