The working process of the utility model is explained as follows:

referring to fig. 8 to 12, when the inflation film manufacturing machine outputs a full length of the plastic film S wound on one reel 17 of the plastic film winding assembly, the plastic film S passes through the front guide roller 5 and is fed to the front of the plastic film winding assembly. The two pairs of fixed supporting heads 28 and the telescopic supporting heads 23 are in horizontal positions at this time, and a reel (i.e. the second reel 17B, the replacing process is described at the end) is just replaced between the rear pair of fixed supporting heads 28 and the telescopic supporting heads 23, and the first reel 17A replaced before is already rotated to the front (as shown in fig. 8); the plastic film S passes through the upper surface of the rotating shaft 6 (roller) of the squeeze roller bracket and the lower surface of the squeeze roller 8 in sequence, and then is wound on the first reel 17A upwards.
