[0072] The working principle of the fruit and vegetable net cutting device and the bagging machine is as follows: one end of the net passes through the through hole 22 of the fixed plate 18, the net limit ring 19, and the net through hole 17 from bottom to top in sequence. The counterweight block 20 and the counterweight tube 21 are used in combination to play a good guiding role, so that the net moves vertically upward. When cutting the net, the cylinder 11 drives the rectangular frame 12 to move forward, and the steering cam 14 drives the steering plate 1 to rotate under the drive of the rectangular frame 12. Since the top of the cutter 4 is inserted into the upper slide groove 6 on the lower surface of the steering plate 1 through the protrusion 7, and the bottom of the cutter 4 is inserted into the lower slide groove 3 under the lower limit bracket 2 through the cutter cam 5, when the steering plate 1 rotates, the six cutters 4 can be brought closer to each other, and finally the sharp corners 4-5 of the six cutters are converged into one point, thereby realizing the cutting of the fruit and vegetable net. Since the guide vertical rod 29 and the net top plate 26 are provided, the net can be supported, which is convenient for cutting and opening the net. The working principle of bagging is as follows: the rotating plate 41 is driven to rotate by the rotating motor 39, and the rotating plate 41 drives the four pulley protrusions 44 to close along the length direction of the guide rail 30, so that the four closed finger frames 34 are inserted into the net sleeve, and then the four pulley protrusions 44 are driven to open along the length direction of the guide rail 30, so as to open the net sleeve, and the fruit and vegetable net sleeve bagging device is driven to move downward as a whole through the external driving mechanism, and the four finger frames 34 are arranged on the periphery of the fruit. At this time, the bag-rolling cylinder 56 drives the finger plate slider 53 to move downward, and the finger plate slider 53 pushes the finger plate 36 from top to bottom. After the finger plate 36 is subjected to force, it rotates with the rotating shaft 35 as the axis, so that the finger pin 37 below the finger plate 36 is closed in the U-shaped opening 36, so that the finger pin 37 is separated from the net mouth of the net sleeve, and in the process of the finger plate slider 53 moving downward, the net sleeve can be separated from the finger frame 34, and the finger pin 37 is separated from the net sleeve, so that the bag-rolling operation is realized, and the net sleeve is arranged on the fruit. The whole process is convenient and fast, and the production cost of the enterprise is reduced.

[0074] Working principle of the rotary lifting device: Since two profile beams 86 for installing bagging machines are provided, two groups of bagging machines can work alternately. When in use, the bagging machine lifting motor 88 drives the first synchronous pulley 89 to rotate, and drives the profile beam 86 to rise and fall through the bagging machine lifting mechanism, thereby driving the bagging machine to rise and fall. Since two bagging machine lifting mechanisms are provided, and the lifting and falling of the two profile beams 86 are independently controlled, the two profile beams 86 can be lifted and fallen separately, further improving work efficiency. When rotating, the bagging machine rotating mechanism drives the receiving plate 100 to rotate.

When the rectangular frame plate 96 rotates, it drives the profile beam 86 to rotate, so that the two profile beams 86 are interchanged with each other and work alternately, thereby improving work efficiency.
