[0030] Working principle of the present invention:

[0031] First, the height of the positioning platform is adjusted by lifting the servo electric cylinder 10 to adjust the folding height according to the thickness of the tray, and the stacked tray 9 and the bubble film 8 are pre-placed on the positioning platform;

[0032] Then, at the same time, the left long side folding knife 11 is driven to move horizontally by the left horizontal cylinder, and the right long side folding knife 51 is driven to move horizontally by the right horizontal cylinder 52, so as to complete the folding of the long sides of the left and right sides of the bubble film 8; and the front horizontal slide plate 73 is driven to slide along the front horizontal slide rail 72 by the rodless cylinder, and the front lifting electric cylinder 74 drives the front lifting and pressing plate 75 to move up and down so that the front lifting and pressing claw 76 presses one end of the bubble film 8 after the folded long side to prevent it from spreading; and the rear horizontal slide plate is driven to slide along the rear horizontal slide rail by the rodless cylinder, and the rear lifting and pressing plate is driven to move up and down by the rear lifting electric cylinder so that the rear lifting and pressing claw presses the other end of the bubble film 8 after the folded long side to prevent it from spreading;

[0033] Then, the front short side lower folding knife 62 is driven to rise and fall by the front lower folding knife cylinder 61, and the rear short side lower folding knife is driven to rise and fall by the rear lower folding knife cylinder, so as to complete the upward folding of the lower short sides of the front and rear sides of the bubble film 8;

[0034] Finally, the horizontal motor 24 drives the synchronous screw 25 to rotate and drives the folding knife 27 on the clamping jaw to move relative or oppositely to adjust the folding width in accordance with the length of the tray 9, and the lifting motor 22 drives the lifting platform 23 to descend so that the folding knife 27 on the clamping jaws completes the downward folding of the short sides of the bubble film 8, and the tray 9 wrapped with the bubble film 8 is clamped by further relative movement of the folding knife 27 on the clamping jaws. At the same time, the lifting electric cylinder 28 drives the lifting and pressing plate 29 to descend and press the bubble film 8, and the front lifting and pressing claw 76 and the rear lifting and pressing claw are withdrawn, so that the bubble film 8 can be folded and the product can be directly taken away through the material taking clamping claw assembly 2, thereby improving efficiency.
