Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, and particularly relates to a packaging device for a photothermal antibacterial food packaging film. Background Art

[0002] Plastic is currently a main material for food packaging, but the extensive use of plastic packaging and its non-degradability have led to serious "white pollution", posing great pressure on the ecological environment. Degradable bio-packaging materials are currently the main research direction for food packaging. Frozen storage is a widely used food preservation method, which can inhibit the growth and reproduction of microorganisms and the activity of enzymes in food, retain the nutritional components in food to the greatest extent, and thus extend the shelf life of food. However, the freezer burn effect caused by freezing will lead to the degradation of food quality and limit the development of the frozen food industry. For frozen foods, psychrophilic microorganisms are the main culprits that reduce food quality and threaten human health, among which Listeria is the most serious. As one of the most lethal cold-tolerant pathogens, Listeria can also grow and reproduce at 2-10°C, causing a large number of food poisoning and fatal incidents. In addition, due to the difference between the vapor pressure on the food surface and the water vapor pressure of the air in contact with the food, the ice crystals on the food surface will sublime, resulting in the loss of moisture in the frozen food, the increase in the relative humidity of the air inside the package, and the condensation of water vapor on the inner side of the package into ice when the temperature fluctuates. Over time, it will not only cause the freezer burn effect, but also lead to the adhesion of the food to the packaging material.

[0003] Therefore, existing manufacturers have developed a photothermal antibacterial packaging film for packaging food to reduce the reproduction of germs during the food thawing process.

[0004] However, when the existing fresh-keeping film guiding and covering packaging machine for food packaging is in use, it cannot work continuously. Often, workers need to manually adjust the position of the fresh-keeping film, etc. After the fresh-keeping film is guided and covered, the fresh-keeping film is hermetically wrapped on the outside of the food. Such a device has a low degree of automation when in use, resulting in low work efficiency. At the same time, the guiding, covering and packaging of the fresh-keeping film often require separate power sources to achieve, which has a high cost. Summary of the Utility Model

Detailed implementation manners

[0023] See Figures 1 to 5 As shown, a packaging device for a photo-thermal antibacterial food packaging film includes a base 11. An upper end surface of the base 11 is provided with a conveying device for moving the packaging film. An interior of the base 11 is used for placing a motor and a control panel. The transmission device and the control panel are electrically connected and are controlled by the control panel to work. The conveying device penetrates a radial end surface of the base 11 and is used for transporting foods to be packaged and a bottom film for packaging.

[0024] Among them, for the conveying device, in this example, the conveying device selects rollers 22. There are several rollers 22. The rollers 22 are abutted against each other, radially arranged and connected. A transmission chain is connected between every two rollers 22 to perform interlocking work.

[0025] The base 11 is provided with a conveying groove 21 with an upward opening. The conveying groove 21 radially penetrates the base 11. The rollers 22 are installed in the conveying groove 21. The conveying groove 21 can accommodate the conveying device, facilitating the upper end surface of the conveying device to be flush with the upper end surface of the base 11 and facilitating the carrying out of the conveying work. One end of the roller 22 is connected to a driving motor. The movement of the food to be packaged and the bottom film is realized through the work of the roller 22. In another embodiment, the roller 22 can adopt the form of a conveyor belt, and there is no limit to the specific selection of the conveying device.

[0026] On the other hand, a fixing frame 16 is connected to an end surface of the base 11. The fixing frame 16 is located on one side of the conveying groove 21. The base 11 is provided with a sunken groove. The fixing frame 16 is fixed in the groove. There are two fixing frames 16. A material cylinder 17 is detachably connected between the two fixing frames 16. The material cylinder 17 is a material tray for the packaging film. After the packaging film is used up, the material tray is replaced.

[0027] Among them, the fixing bracket 16 may be provided with a sunken groove. The barrel 17 is connected with a support rod, and both ends of the support rod are inserted into the groove, and there is no structure for locking the support rod in the groove, which facilitates the rotation of the barrel 17 during operation to release the installation film.

[0028] The base 11 is connected with a bracket 12 on the upper side of the conveying device. The bracket 12 is movably connected with a pressing surface 31. There are two brackets 12. The pressing edge 31 is located between the two brackets 12. The pressing surface 31 is used to cover the packaging film and the food. The pressing surface 31 is made of deformable material. The pressing surface 31 is mainly in the shape of strips. In order to control the sufficiency of the contact between the packaging film and the food by the form of covering and pressing. In this embodiment, wire mesh can be selected. The pressing surface 31 needs to have its own toughness and can return to the initial state after contact. At the same time, during the covering and pressing process, it can be in full contact with the food.

[0029] Among them, one end of the pressing surface 31 is connected with a rotating shaft 34. The rotating shaft 34 is fixedly connected with the pressing surface 31. The rotating shaft 34 is rotatably connected with the bracket 12. There is a certain gap between the rotating shaft 34 and the conveying device to prevent the pressing surface 31 from being in direct contact with the food film all the time. And the other end surface of the pressing surface 31 is connected with a connecting rod 32. The upper end surface of the bracket 12 is connected with a top plate 13. A connecting spring 33 is connected between the top plate 13 and the connecting rod 32. The connecting spring 33 can ensure that the pressing surface 31 can move and contact the food film, and at the same time, it can still return after contact.

[0030] A covering and pressing device is arranged above the pressing surface 31. The covering and pressing device can control the pressing surface 31 to press down to the food film. The covering and pressing device includes a movable frame 35. The two ends of the movable frame 35 are provided with connecting slide rails and are slidably connected with the bracket 12. The movable frame 35 can slide in the horizontal direction to adjust the position. And the lower side of the movable frame 35 is connected with a hydraulic rod 36. And the lower side of the hydraulic rod 36 is connected with a pressing shaft 37. The hydraulic rod 36 can move telescopically in the vertical direction to control the movement of the pressing shaft 37. To ensure the stability of the movement, two hydraulic rods 36 can be arranged and symmetrically connected to the pressing shaft 37.

[0031] The lower end surface of the pressing shaft 37 is an arc surface. The pressing shaft 37 contacts the pressing surface 31 and then contacts the food film, which is conducive to the full contact between the food film and the food. A heating device can be connected to the pressing shaft 37. Through the heating device, the food film can be melted by heat to complete the sealing work.

[0032] A connecting rod 14 is provided on the upper end surface of the top plate 13, and a guide shaft 15 for guiding the installation film is connected to the connecting rod 14. The connecting rod 14 is slidably connected to the top plate 13, and the connecting rod 14 can control the movement of the guide shaft 15. After the barrel 17 discharges the material, the food film will bypass the guide shaft 15 and cover the food, and then the packaging work is realized through the covering and pressing device. The guide shaft 15 can ensure that the food film will not directly contact the food during the early transportation process. Through the movement of the connecting rod 14, the position of the food film can also be adjusted to facilitate the subsequent covering and pressing work.
