At the same time, the fixed plate 13 drives the buffer spring 15 to compress and elastically deform, and the sliding plate 16 moves downward to drive the extrusion rod 210 to move, so that the extrusion rod 210 squeezes the inclined plate 28 to drive the sliding frame 26 to move, and the movement of the sliding frame 26 drives the telescopic rod 27 to contract, and at the same time drives the reset spring 29 to compress and elastically deform, until the extrusion rod 210 moves below the inclined plate 28, and then the cutter 17 drives the extrusion bar 3 12 squeezes the sliding rod 37 and the second rack 38 to move downward, the movement of the sliding rod 37 drives the telescopic spring 39 to compress and elastically deform, and the movement of the second rack 38 drives the squeezing block 311 away from the protrusion 310.

At this time, the driving roller 34 stops moving downward, and then the second rack 38 continues to drive the second gear 36 and the ratchet 4 to rotate. The rotation of the second gear 36 will not drive the driving roller 34 to rotate. When the cutter 17 completes cutting the packaging bag, the telescopic hydraulic cylinder 12 drives the sliding plate 16 and the cutter 17 to reset, so that the telescopic spring 39 drives the sliding rod 37 and the second rack 4 to rotate. The bar 38 is reset, and the second rack 38 drives the second gear 36 and the ratchet 4 to rotate.

Under the action of the first gear 24 and the first rack 23, the fixed block 25 drives the two U-shaped plates 22 to move outward, and the movement of the U-shaped plate 22 drives the first rack 23 to squeeze the thrust spring 211 to compress and elastically deform. At the same time, the two U-shaped plates 22 drive the two placement plates 21 to move away from each other, so that the cut packaging bag falls on The packing bags are stacked on the discharge plate 53 in sequence, so that the packaging bags are neatly stacked. The placement plate 21 moves to drive the installation sleeve 55, the movable bar 56 and the pressure rod 57 to move. The installation sleeve 55 moves to drive the insertion rod 58 and the connecting rod 510 to move. When the pressure rod 57 contacts the inclined block 54 and moves to the top of the inclined block 54, the inclined block 54 resists the pressure rod 57 to enter the installation sleeve 55, and drives the compression spring 512 to be compressed and elastically deformed. Since the installation spring 59 is in a stretched state, the installation spring 59 drives the insertion rod 58 to enter the slot 511, so as to fix the movable bar 56. When the extrusion rod 210 is away from the inclined plate 28, the thrust spring 211 drives the first rack 23, the U-shaped plate 22 and the placement plate 21 to reset.The placement plate 21 drives the installation sleeve 55, the movable bar 56 and the pressure rod 57 to reset. When the connecting rod 510 contacts the fixed box 5, the connecting rod 510 pulls the insertion rod 58 away from the movable bar 56, so that the connecting spring 52 drives the movable bar 56 and the pressure rod 57 to reset, so that the pressure rod 57 compacts the stacked packaging bags. As the thickness of the packaging bag increases, the squeezing force of the connecting spring 52 on the packaging bag increases. When the thickness of the packaging bag reaches the set thickness, the connecting spring 52 squeezes the packaging bag and the discharge plate 53 to separate from the sliding pin 51 and fall on the bottom inner wall of the workbench 1. The discharge plate 53 moves to squeeze the sliding pin 51 to move and enter the fixed box 5. The movement of the sliding pin 51 drives the connecting spring 52 to compress and elastically deform. When the discharge plate 53 is away from the sliding pin 51, the connecting spring 52 drives the sliding pin 51 to reset. At this time, the staff puts another discharge plate 53 again, realizing automatic discharge of the packaging bag.
