The controller 15 controls the motor 18 to pause and controls the cylinder 16 to extend or retract. The output end of the cylinder 16 drives the first fixed tube 13 to move, and the first fixed tube 13 drives the elastic hose 11 and the second fixed tube 24 to move. The second fixed tube 24 drives the collecting frame 20 to move, and the collecting frame 20 drives the U-shaped cleaning block 25 to move, so that the U-shaped cleaning block 25 moves along the side wall of the sealing knife 8 to clean the sealing knife 8.

[0042] At the same time, the vacuum cleaner 12 is started.

[0043] The cut products are then conveyed to the unloading conveying platform 7, which conveys the products and starts the fan 30. The fan 30 concentrates the hot air inside the heat shrink box 6 and blows it onto the film of the product to shrink the film quickly. Before use, the distance between the two mounting plates 29 needs to be adjusted according to the width of the product, and the second electric telescopic rod 28 is started. The output end of the second electric telescopic rod 28 drives the mounting plate 29 to move, and the mounting plate 29 drives the fan 30 to move so that the fan 30 is close to the product. Then the first electric telescopic rod 26 is started. The output end of the first electric telescopic rod 26 drives the mounting block 27, the second electric telescopic rod 28, and the mounting plate 29 to move, so that the lower end of the mounting plate 29 is close to the upper end of the unloading conveying platform 7.
