[0002] With the rapid development of economic consumption, the use of plastic packaging bags is also alarming. The impact brought about by this is environmental pollution. There are inevitably discarded packaging bags on the streets and alleys, and plastic waste is increasing. Against this background, new green and environmentally friendly packaging bags have emerged. Its research and development and application are undoubtedly a great help to the ecology. After the packaging bags are packed, they need to be sealed. The sealing machine is a machine that seals the container filled with packaging. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, the packaging container needs to be sealed. This operation is completed on the sealing machine. Simply put, a sealing machine refers to a machine that seals the container after the packaging container is filled with products.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reference Figure 1-2The utility model provides an embodiment of an environmentally friendly packaging bag sealing machine, comprising a base 1, the upper surface of the base 1 is fixedly connected with a supporting foot 2, the upper surface of the supporting foot 2 is fixedly connected with a processing table 3, the interior of the processing table 3 is fixedly connected with a breathable plate 4, the lower surface of the processing table 3 is fixedly connected with a purification box 5, the outer wall of the purification box 5 is fixedly connected with an air pump 6, the input end of the air pump 6 is fixedly connected with an exhaust pipe 7, the outer wall of the exhaust pipe 7 is fixedly connected to the interior of the purification box 5, the outer wall of the purification box 5 is fixedly connected with a connecting pipe 8, the outer wall of the connecting pipe 8 is fixedly connected with a shunt pipe 9, the top of the shunt pipe 9 is fixedly connected with a suction nozzle 10 which is symmetrical in center, the outer walls of the shunt pipe 9 and the suction nozzle 10 are fixedly connected to the interior of the processing table 3, the interior of the purification box 5 is slidably connected with two symmetrical permeable membranes 11, the outer walls of the permeable membranes 11 are fixedly connected with handles 12, and a moving component is arranged on the upper surface of the base 1.

[0035] Specifically, during the packaging process, the air pump 6 is started to extract the air in the purification box 5 through the exhaust pipe 7. As the air inside the purification box 5 decreases, a strong suction force comes into being. This suction force further extracts the air in the diversion pipe 9 through the connecting pipe 8. At this time, the gas generated by the packaging bag is attracted by this suction force and is smoothly sucked into the purification box 5. The material of the packaging bag is PLA, which will produce carbon dioxide. These gases enter the filter and then pass through the two permeable membranes 11 inside the purification box 5 for filtration treatment. The material of the filter membrane 11 is polyamide, which ensures that the gas is effectively purified and prevents it from being directly discharged into the environment to cause pollution.

[0036] Reference Figure 3-4 The moving component includes a fixed plate 13, the outer wall of the fixed plate 13 is fixedly connected to an electric slide rail 14, the outer wall of the electric slide rail 14 is slidably connected to an electric slider 15, the lower surface of the fixed plate 13 is fixedly connected to the upper surface of the base 1, the outer wall of the electric slider 15 is fixedly connected to a connecting plate 16, the outer wall of the connecting plate 16 is fixedly connected to an electric push rod 17, the driving end of the electric push rod 17 is fixedly connected to a moving plate 19, the outer wall of the moving plate 19 is fixedly connected to an encapsulation roller 18, the lower surface of the encapsulation roller 18 is fixedly connected to an encapsulation strip 20, the outer wall of the encapsulation strip 20 is fixedly connected to a heater 21, the outer wall of the encapsulation roller 18 is fixedly connected to a diverter 22, the outer wall of the diverter 22 is fixedly connected to an exhaust fan 23, and the bottom end of the diverter 22 is fixedly connected to a plurality of exhaust pipes 24.

[0037] Specifically, the electric slide rail 14 enables the electric slider 15 to move smoothly. The electric slider 15 is connected to the connecting plate 16. As the electric slider 15 moves, the connecting plate 16 also moves downward accordingly. This moving mechanism allows us to easily adjust the position of the packaging roller 18 and the packaging strip 20, so as to better adapt to packaging bags of different sizes and shapes. Next, the electric push rod 17 plays a driving role in the system. When the electric slider 15 moves, the electric push rod 17 will push the moving plate 19 to make it move accordingly. This design makes the entire system more flexible and can quickly adjust the position according to actual needs. The exhaust fan 23 extracts the air inside the diverter 22. This process is crucial to ensure the sealing of the packaging bag, because the vacuum treatment can effectively remove the air in the packaging bag, thereby improving the sealing effect. In order to further improve the sealing quality, the heater 21 will heat the packaging roller 18, and the packaging roller 18 will transfer the heat to the packaging strip 20, and the packaging strip 20 will then perform a packaging process on the packaging bag. This heating method helps the packaging strip 20 to better adhere to the packaging bag, thereby improving the firmness of the seal.

[0038] Reference Figure 1 and Figure 5 A support plate 25 is fixedly connected to the upper surface of the base 1, a motor 27 is fixedly connected to the outer wall of the support plate 25, an output end of the motor 27 is transmission-connected to a conveyor belt 26, a bracket 28 is fixedly connected to the upper surface of the support plate 25, a rubber roller 29 is rotatably connected to the inside of the bracket 28, a cabinet door 32 is rotatably connected to the outer wall of the base 1, a handle 33 is fixedly connected to the outer wall of the cabinet door 32, a support plate 2 30 is fixedly connected to the right side of the outer wall of the base 1, and a plurality of conveying rollers 31 are rotatably connected to the inside of the support plate 2 30.

[0039] Specifically, the packaging bag is placed on the conveyor belt 26, and the motor 27 is gently started, and the conveyor belt 26 begins to rotate slowly. The rotation of the motor 27 drives the conveyor belt 26, so that the packaging bag begins its transportation process. During the transportation process, the position of the packaging bag is restricted by the rubber roller 29, and the rubber roller 29 is connected to the conveyor belt 26 through the bracket 28. This design cleverly prevents the packaging bag from falling during transportation, ensuring that each packaging bag can complete the entire transportation process safely and smoothly.

[0040] Working principle: when the device needs to be used, first place the packaging bag on the upper surface of the conveyor belt 26, start the motor 27 to drive the conveyor belt 26 to transport the packaging bag, and during the transportation of the packaging bag, the rubber roller 29 connected to the bracket 28 limits the position of the packaging bag, so as to prevent the packaging bag from falling during the transportation. Then the worker places the packaging bag to be packaged on the processing table 3 on the upper surface of the supporting foot 2, starts the electric slide rail 14 to make the electric slider 15 move downward with the connecting plate 16, and pushes the moving plate 19 to move through the electric push rod 17, so as to facilitate the adjustment of the position of the packaging roller 18 and the packaging strip 20, starts the exhaust fan 23 to extract the air inside the diverter 22, and then vacuumizes the packaging bag through multiple exhaust pipes 24, and then starts the heater 21 to heat the packaging roller 18, and then seals the packaging bag. The roller 18 transfers heat to the packaging strip 20, and the packaging strip 20 is used to package the packaging bag, and the sealing effect of the packaging bag is improved by vacuuming. When packaging, the air pump 6 is started to extract the air inside the purification box 5 through the exhaust pipe 7, and the air inside the purification box 5 is reduced to generate suction. Then the air inside the shunt pipe 9 is extracted through the connecting pipe 8, and the gas generated by the packaging bag is sucked into the purification box 5 through the shunt pipe 9 and the connecting pipe 8 through the suction nozzle 10. The gas is filtered through the two layers of permeable membrane 11 inside the purification box 5 to prevent direct discharge of the gas to cause environmental pollution. The permeable membrane 11 can be conveniently moved out of the purification box 5 by pulling the handle, so as to facilitate the cleaning or replacement of the permeable membrane 11. Finally, the packaged packaging bag is placed on the upper surface of the conveying roller 31, and the packaging bag is conveniently unloaded through the rolling action of the conveying roller.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
