At this time, the ends of the first push rod 14 on the first clamping movable support bar 12 and the second clamping movable support bar 13 are respectively contacted with the surface of the packaging bag in the working channel 1A to clamp the packaging bag in the working channel 1A;

[0081] Step 3: The first cam rotates to drive the bag opening and closing mechanism 32 to move intermittently, so that the suction nozzles 35 on the first bag opening movable frame 33 and the second bag opening movable frame 34 move close to / far from each other, and the suction nozzles 35 absorb the surface of the packaging bag and move outward at the same time to complete the bag opening work.

[0082] Step 4: When the first push rods 14 on the first clamping movable support bar 12 and the second clamping movable support bar 13 make similar movements, the first push rods 14 and the second flattening movable claws 44 on the first flattening movable frame 42 and the second flattening movable frame 43 make similar movements synchronously, the first push rods 14 clamp one side of the surface of the packaging bag, and the flattening claws 44 clamp the other side of the surface of the packaging bag. Then, the fourth cam plate 56 rotates to drive the flattening shaft 41 to rotate, so that the flip shaft 45 flips intermittently, and under the action of the connecting block, the first flattening movable frame 42 and the second flattening movable frame 43 move horizontally along the conveying direction of the packaging bag, thereby flattening the opening of the packaging bag.

[0083] Step 5: After completing steps 3 and 4, repeat the action of step 1 and at the same time, the first push rod 14 releases the clamping of the packaging bag, and the second push rod 24 alternately clamps the packaging bag between the first push rods 14 and moves it forward one workstation. The second push rod 24 located at the end of the first transfer movable support bar 22 and the second transfer movable support bar 23 moves the packaging bag that has completed the packaging work at the end of the working channel 1A to the outside of the working channel 1A for collection.

[0084] The first, second, third and fourth cam plates of this embodiment adopt an inner cam groove design, which has no external force pressure compared to the prior art and can increase the service life.

[0085] The actions of the clamping mechanism, the transfer mechanism, the bag opening mechanism and the flattening mechanism are realized by mechanical connection respectively, which has the advantages of low cost, good action continuity and synchronization, and stable actions of each mechanism during continuous operation of the equipment.
