The film roll is sealed and after cutting, the cut film roll is moved to a position relative to the clamping device 2. The clamping cylinder 2171 drives the clamping block 2173 to approach the constant block 2172. At this time, the film roll is located on one side of the constant block 2172 until the clamping block 2173 abuts against the constant block 2172 to complete the clamping of the film roll. At this time, the film roll is flat, and then the transverse cylinder 215 drives one transverse block 212 to move, and then drives the other transverse block 212 to move through the linkage rod 214 and the linkage block 213. At this time, the two clamping jaws 217 move toward each other, the two sides of the film roll are close, and the film roll appears corrugated, and then the two The film suction head 218 on the side approaches the roll film, sucks one side of the roll film, and then moves away from the roll film. At this time, the roll film is opened, and the feeder 23 can pour the material into the roll film. During the material adding process, the bottom of the roll film is opposite to the support bucket 256. At this time, the support bucket 256 is in the supporting position.
