The positioning strips 4244 abut against the auxiliary plate 4211 to position the material roll. After positioning, it is convenient for the cutter 4233 to cut and separate the material roll, or for the sealing cylinder 4243 to push the heating strips 4242 to perform heat sealing operations on the material roll. Two positioning strips 4244 are arranged at intervals above the heating strips 4242, and one positioning strip 4244 is arranged below the heating strips 4242. The two positioning strips 4244 above the heating strips 4242 are used for cutting and separating by the cutter 4233, and the two positioning strips 4244 above and below the heating strips 4242 are used for positioning the material strip during sealing.

The first support rod 51 and the second support rod 52 are both fixedly installed in the mounting frame 10. The two ends of the first moving rod 53 and the second moving rod 54 are slidably connected to the first support rod 51 and the second support rod 52, respectively. Two internal support mechanisms 55 are respectively provided on the first moving rod 53 and the second moving rod 54. The movement path of each internal support mechanism 55 is perpendicular to the movement path of the first moving rod 53 and the second moving rod 54. The first support rod 51 and the second support rod 52 are respectively located near the feeding side and the discharging side of the mounting frame 10. The moving rods 54 move closer to or further away from the carton conveying path on both sides of the carton conveying path. The two inner support mechanisms 55 located on the first moving rod 53 or the second moving rod 54 move back and forth in the direction of approaching or moving away from the feeding side or discharging side of the mounting frame 10. The relative movement of the first moving rod 53 and the second moving rod 54, together with the relative movement of the four inner support mechanisms 55 in pairs, realizes that the four inner support mechanisms 55 approach each other and move away from each other, forming support for the opening of the plastic bag. At the same time, the inner support negative pressure head 553 of the inner support mechanism 55 extends downward long enough to form a large support surface for the side wall of the plastic bag, avoiding the bag opening being too large and causing the middle area to sag.

[0053] In another embodiment of this utility model, such as Figure 6 As shown, the inner support mechanism 55 includes a lifting module 551, a telescopic rod 552, and an inner support negative pressure head 553.

Each lifting module 551 is fixedly installed in pairs on the two moving ends of the first moving rod 53 and the two moving ends of the second moving rod 54. The telescopic end of the telescopic rod 552 is fixedly installed downward on the lifting end of the lifting module 551. The inner support negative pressure head 553 is installed on the telescopic end of the telescopic rod 552. The lifting module 551 works with the telescopic rod 552 to achieve two-stage movement to ensure that the inner support negative pressure head 553 is accurately moved to the bottom of the bag. The bottom end of the negative pressure head is set with an arc-shaped curved surface to prevent the bag from being torn.

[0054] In another embodiment of this utility model, such as Figures 7-8As shown, the bagging support device 60 includes a first lifting device 61, a second lifting device 62, a lifting beam 63, and two suction devices 64.

The two suction devices 64 are both fixedly mounted on the lifting beam 63, and the two suction devices 64 are respectively positioned close to the two ends of the lifting beam 63. The free ends of the two suction devices 64 are inclined towards each other. The first lifting device 61 and the second lifting device 62 drive the lifting beam 63 to move up and down, moving closer to and away from the carton, or closer to and away from the opening device 50, so that the plastic bag with the bag opening is placed on the four telescopic rods 552. The four telescopic rods 552 move to fully expand the plastic bag. Then, the four suction devices 64 of the two bagging support devices 60 re-adhere and grab the fully expanded plastic bag. The four telescopic rods 552 retract, detaching from the support of the plastic bag. The four suction devices 64 move down to put the plastic bag into the carton.

The telescopic end of the telescopic cylinder 644 is fixedly connected to the movable positioning head 645. The adsorption head 643 adsorbs and grips the plastic bag. The movable positioning head 645 includes a movable plate 6451, a positioning motor 6452, and a positioning roller 6453. The movable plate 6451 is slidably installed on the carrier plate 642, and the movable end of the telescopic cylinder 644 is fixedly connected to the movable plate 6451. Next, the positioning motor 6452 is fixedly installed on the moving plate 6451, and the positioning roller 6453 is vertically rotatably installed on the upright plate of the moving plate 6451. The rotating end of the positioning motor 6452 is connected to the positioning roller 6453 by a transmission belt, which drives the positioning roller 6453 to rotate. The positioning cylinder 6451 pushes the moving plate 6451 closer to the adsorption head 643. The positioning roller 6453 abuts against the side of the adsorption head 643. The rotation of the positioning roller 6453 pushes the edge of the plastic bag adsorbed on the adsorption head 643 to be located between the adsorption head 643 and the positioning roller 6453. The forward and reverse rotation of the positioning roller 6453 pushes the edge of the plastic bag opening into the adsorption head 643 and the positioning roller 6453 or pushes the edge of the plastic bag opening out of the adsorption head 643 and the positioning roller 6453.
