These 2 connecting shafts have the same structure, and one of the connecting shafts 245 is described below as an example. The connecting shaft 245 is provided with 2 linear bearings 246, and the linear bearings 246 are in close contact with the second left clamping plate 214.

In order to drive the second left clamp plate 214 to move back and forth between the first left clamp plate 213 and the second vertical seat 241, the first clamping portion may further include a fourth cylinder (duplex cylinder) 251, a roller seat 252, 2 roller needle bearings 253, and 2 movement stoppers 254 (only one roller needle bearing 253 and one movement stopper 254 are shown in fig. 6). The fourth cylinder 251 is fixedly arranged on the bag opening base 201, the fourth cylinder 251 is connected with the roller needle roller seat 252 through bolts, the 2 roller needle bearings 253 are respectively installed at two ends of the roller needle roller seat 252, the movable limiting blocks 254 are respectively abutted against the corresponding roller needle roller bearings 253, and each movable limiting block 254 is respectively fixedly connected with one of the corresponding second group of clamping plates (namely, one movable limiting block is fixedly connected with the second left clamping plate 214, and the other movable limiting block is connected with the second right clamping plate 212). When moving, the fourth cylinder 251 drives the roller pin seat 252 to move, and the movement is transmitted to the movement limiting block 254 through the roller needle bearing 253 on the roller pin seat 252, and further transmitted to the second left clamping plate 214 and the second right clamping plate 212, so that the second left clamping plate 214 and the second right clamping plate 212 move. With the above embodiment, the second right clamping plate 212 and the second left clamping plate 214 can move back and forth with respect to the first right clamping plate 211 and the first left clamping plate 213, and since 4 clamping plates can move left and right, 4 chucks can clamp the packing bag.

With continued reference to fig. 5-7, the bag opening portion of the first bag opening assembly 20 may include: 2 bottom plate supports 261 and 262, bag opening suction cup bottom plate 263, fifth air cylinder (duplex air cylinder) 264, 2 bag opening suction cup supports 265 and 266, suction cups 256, 257, 258, 259. Wherein, the bottom plate supports 261 and 262 are fixedly arranged on the bag opening base 201, and the bag opening sucker bottom plate 263 is connected with the bottom plate supports 261 and 262 and is parallel to the bag opening base 201. The fifth cylinder 264 is arranged on the bag opening suction cup base plate 263, 2 bag opening

suction cup brackets

265 and 266 are respectively arranged at the front end and the rear end of the fifth cylinder 264, and 2 vacuum suction cups, namely 4

vacuum suction cups

271, 272, 273 and 274 are respectively arranged at the top end of each bag opening suction cup bracket. The fifth air cylinder 264 can drive the bag opening

suction cup brackets

265 and 266 to synchronously move back and forth, wherein the synchronous back and forth movement refers to that when the bag opening suction cup bracket 265 moves forward, the bag opening suction cup bracket 266 simultaneously moves backward; when the bag opening suction cup holder 265 moves backward, the bag opening suction cup holder 266 moves forward at the same time, that is, the bag opening suction cup holder 265 and the bag opening suction cup holder 266 move in the opposite direction or in the opposite direction in synchronization. Thus, 4 vacuum chucks move synchronously to suck and open the packaging bag. It should be noted that the heights of the 4 vacuum suction cups of the bag opening portion may be the same as the heights of the 4 chucks of the first clamping portion.

When the first bag opening assembly 20 performs the bag opening action, the clamping heads 216 and 218 move towards the clamping heads 215 and 217 synchronously, the clamping heads clamp the packaging bags after approaching contact, and the clamping positions can be positioned at the left side and the right side of the bag opening. And then, the vacuum suction cups are close to and contact with the packaging bags, the vacuum suction cups suck the bags from two sides respectively, and the positions where the vacuum suction cups suck the bags can be the middle positions of the bag openings. Then, the vacuum chuck moves synchronously to pull the packaging bag, simultaneously, the 4 chucks also move synchronously to the middle, the bag opening is pulled open, and the first bag opening action is completed.
