The second suction cup 431 is connected to an external compressor through an external air pipe, and the external compressor controls the operation of the second suction cup 431. The rotary cylinder 423 is rotatably connected to the rotating seat 42, and the output shaft of the rotary cylinder 423 is rotatably connected to the rotating plate 421. The rotary cylinder 423 drives the rotating plate 421 to rotate on the rotating seat 42, so that the second connecting plate 43 moves and moves closer to the feeding port and the first connecting plate 41 in sequence.

[0031] During operation, the rotary cylinder 423 pushes the rotary plate 421 to rotate 90°, so that the second connecting plate 43 is located below the feeding port. The push cylinder 422 pushes the second connecting plate 43 to rise, so that the second suction cup 431 touches the packaging bag 111 located at the bottom of the material trough 11. The second suction cup 431 adsorbs the packaging bag 111. The push cylinder 422 pulls the second connecting plate 43 to descend, and pulls the packaging bag 111 out of the feeding port.

[0032] Rotary cylinder 423 pushes rotating plate 421 to rotate -90°, causing second connecting plate 43 to approach first connecting plate 41, making second connecting plate 43 opposite to first connecting plate 41. Propulsion cylinder 422 pushes second connecting plate 43 even closer to first connecting plate 41, first suction cup 411 adsorbs packaging bag 111, propulsion cylinder 422 pulls second connecting plate 43 away from first connecting plate 41, first connecting plate 41 and second connecting plate 43 open the opening of packaging bag 111, guide cylinder 32 pushes guide plate 321 to slide down, bottom of guide plate 321 enters through opening at top of packaging bag 111, allowing packaging bag 111 to fully open; feeding plate 21 puts product into guide plate 321, guide plate 321 assists product to fall into packaging bag 111, completing the automatic product placement into packaging bag 111.

[0036] A connecting plate 6 is fixedly connected inside the housing 1. A lifting cylinder 61 is fixedly connected to the connecting plate 6. A bearing plate 611 is fixedly connected to the output shaft of the lifting cylinder 61. The bearing plate 611 is located below the first connecting plate 41 and the second connecting plate 43. The lifting cylinder 61 pushes the bearing plate 611 closer to the first connecting plate 41. When the packaging bag 111 is used to place the product, the lifting cylinder 61 pushes the bearing plate 611 to touch the packaging bag 111, supporting the packaging bag 111 to place the product. After the packaging bag 111 has finished placing the product, the first suction cup 411 and the second suction cup 431 stop adsorbing the packaging bag 111. The lifting cylinder 61 pulls the bearing plate 611 down, which also drives the packaging bag 111 down.

[0042] The support plate 611 is lower than the pusher plate 811. After the packaging bag 111 is sealed, the pusher cylinder 81 pushes the pusher plate 811 close to the unloading plate 82. The pusher plate 811 pushes the packaging bag 111 into the unloading plate 82. The packaging bag 111 slides from the unloading plate 82 into the unloading conveyor belt 83. The unloading conveyor belt 83 sends the packaging bag 111 out of the equipment.

[0043] This utility model provides a packaging machine. Multiple packaging bags are placed in a material trough. A rotating mechanism drives a second connecting plate to rotate and approach the feeding port via a rotating plate. A second suction cup adsorbs the packaging bags placed at the bottom of the material trough. The rotating mechanism drives the second connecting plate to rotate and approach the first connecting plate. A propulsion cylinder pushes the second connecting plate closer to the first connecting plate, causing the packaging bag to touch the first suction cup. The first suction cup then adsorbs the packaging bag. The propulsion cylinder pulls the second connecting plate away from the first connecting plate, causing the first and second connecting plates to unfold the packaging bag. After a lifting cylinder pushes the connecting plate to touch the packaging bag, the feeding mechanism feeds the product into the packaging bag. The first and second suction cups release the packaging bag, and the lifting cylinder pulls the connecting plate and the packaging bag down synchronously. A sealing mechanism melts the opening of the packaging bag.
