[0033] The packaging box body 1 is in the shape of a rectangular parallelepiped. The packaging box body 1 and the perforated metal plate 2 are fixedly connected. A plurality of storage slots 4 are arranged in sequence in a horizontal shape in the middle of the top surface.

[0034] The packaging box body 1 and the metal column 5 are movably connected. The metal column 5 is cylindrical in shape, and the middle part is circular groove-shaped. The perforated metal plate 2 and the peduncle shearing device 3 are fixed by bolt connection.

[0035] The packaging box 1 and the cling film roller transmission device 6 are connected and fixed by a rotating shaft, and the cling film roller transmission device 6 is symmetrically arranged on both sides of the upper inner part of the packaging box 1. The packaging box 1 and the supporting frame 7 are fixedly connected, and the supporting frame 7 is a frame setting.

[0036] The support frame 7, the cling film heat sealing device 8, the fixed spring clamp 9, the strapping device 10, the vacuum pump 11, the vacuum extraction device 12, the gas filling device 13 and the pump body 14 are all spliced ​​and assembled, and are all connected and fixed to the support frame 7 by bolts.

[0037] The cling film heat sealing device 8 and the fixed spring clamp 9 are symmetrically arranged in two groups, which are respectively arranged on the upper parts of both sides of the support frame. The bundling device 10 is placed at the bottom end of the storage slot 4, and the bundling device 10 is fixed to the top surface of the middle support frame body 7.

[0038] The vacuum pump 11, the vacuum pumping device 12, the gas filling device 13 and the pump body 14 are all powered by connecting to an external circuit for use.

[0039] Specifically, the structure comprises a packaging box 1, a perforated metal plate 2, a peduncle shearing device 3, a storage slot 4, a metal column 5, a plastic wrap roller transmission device 6, a support frame 7, a plastic wrap heat sealing device 8, a fixed spring clamp 9, a strapping device 10, a vacuum pump 11, a vacuum device 12, a gas filling device 13, a pump body 14, an exhaust port 15 and a gas cylinder connecting pipe 16 to form a modified atmosphere fresh-keeping packaging device for fresh cut flowers. The packaging box 1 combines a variety of flower preservation technologies such as vacuuming, modified atmosphere packaging, and sealed packaging. It is installed inside to form an integrated design, so that the fresh-keeping effect of flowers is better. The perforated metal plate 2 provides support for the fresh-keeping film, which is convenient for forming a cylindrical film barrel. The excess flower stalks are cut off by the stalk cutting device 3 to ensure that the length of each flower is basically the same. The metal column 5 is placed through the storage slot 4, and the fresh-keeping film is continuously supplied through the fresh-keeping film roller transmission device 6 to ensure continuous production. The various fresh-keeping technical structures are fixed inside the packaging box 1 through the support frame 7 to maintain stability. The plastic wrap heat sealing device 8 can achieve rapid sealing, so that the flower branch is isolated from the outside air in the plastic wrap, and the flower branch is fixed by fixing the spring clamp 9 to ensure that the flower branch is moved to the required position during the packaging process. The plastic wrap and the flower stalk are tied tightly with a wire by the bundling device 10 to prevent the flower from shaking greatly in the film barrel after subsequent inflation. The vacuum pump 11 is used for vacuuming, and the vacuuming device 12 is used to extract the air in the space formed by the plastic wrap wrapping the flower branch, and the air is exhausted through the exhaust port 15 at the same time. The plastic wrap wrapped with the flower branch is filled with the prepared gas that can play a preservation role through the gas filling device 13, and the external gas cylinder is connected through the pump body 14 and the gas cylinder connecting pipe 16 to provide power for the gas filling device. The gas-controlled fresh-keeping packaging device of the fresh cut flower needs an electric device, which is powered by connecting an external power supply, so that the overall packaging operation has a high degree of mechanization and automation, and the production efficiency is significantly improved, which improves the economic benefits. The packaging material cost is lower than that of traditional packaging, and large-scale production saves costs.

[0040] Working principle: Wrap fresh cut flowers in a highly elastic and ductile sealed plastic wrap, remove some of the air, and fill it with a certain amount of composite gas. While the composite gas is used to extend the shelf life of the cut flowers, the plastic wrap isolates the flowers from the air environment, avoiding the effects of exogenous microorganisms on the flowers. The air bags formed by the inflated film can effectively protect the cut flowers from mechanical damage such as squeezing during transportation and sales.

[0041] Working process: The metal column 5 is punched through the perforated metal plate 2, so that the high-elasticity and high-ductility preservative film on the perforated metal plate 2 is covered by the cling film roller transmission device 6 to form a nearly cylindrical film barrel, and the fresh cut flowers are placed in the film barrel with the flowers facing downwards, and the fixed spring clamps 9 under the perforated metal plate 2 are closed to clamp the pedicels to fix the cut flowers, and the binding device 10 under the fixed spring clamps 9 uses a wire to tie the cling film and the pedicels tightly to prevent the flowers from shaking greatly in the film barrel after subsequent inflation, and the pedicel shearing device 3 on the perforated metal plate 2 is started to cut off the excess pedicels, and the fixed spring clamps 9 are pressed down. Move a certain distance to leave a certain space for the cling film heat sealing device 8, connect an external power supply, start the vacuum device 12, extract the air in the film barrel, but not completely, to ensure that the film does not press on the flowers and cause mechanical damage, start the gas filling device 13, fill a certain amount of composite gas in the film barrel, the filling amount is enough to form a pressure-resistant air bag in the film barrel, but not to the point of causing the film barrel to explode, start the cling film heat sealing device 8 above the fixed spring clamp 9, seal the cling film, effectively preserve the fresh cut flowers, realize the overall multifunctional preservation technology in one piece, and improve the overall preservation efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
