[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1
[0019] Please see Figure 1-5 In this embodiment: a multifunctional plastic bag processing equipment includes a base 1, a feeding roller frame 2 and an inlet roller frame 3 are installed on one side of the upper surface of the base 1, a water hanging component is installed on one side of the middle of the upper surface of the base 1, a drying box 4 is fixedly connected to the other side of the upper surface of the base 1, an upper tension roller 6 is rotatably connected to the upper two sides of the drying box 4, a lower tension roller 7 is rotatably connected to the lower two sides of the drying box 4, a heater 8 and a filter box 13 are fixedly connected to one side of the base 1, an air outlet pipe 9 is fixedly connected to the output end of the heater 8, a diversion pipe 10 is fixedly connected to one end of the air outlet pipe 9, the two ends of the diversion pipe 10 are fixedly connected to the upper and lower sides of the inner wall of the drying box 4, nozzles 11 are fixedly connected to both sides of the adjacent surfaces of the diversion pipe 10, and an air suction pipe 12 is fixedly connected to the input end of the heater 8, one end of the air suction pipe 12 is fixedly connected to one side of the filter box 13.
[0020] In this embodiment, the plastic bags are evenly conveyed into the drying chamber 4 by the cooperation of the feeding roller frame 2 and the guide roller frame 3. The feeding roller frame 2 and the guide roller frame 3 ensure that the plastic bags are subjected to uniform force during the conveying process, avoiding deviation and uneven tension. During the conveying process, the plastic bags are first treated by the water-removing component to scrape off the moisture on the surface of the plastic bags, effectively reducing the moisture content before entering the drying stage, thereby shortening the drying time. The plastic bags complete the drying process in the drying chamber 4. Inside the drying chamber 4, the upper tension roller 6 and the lower tension roller 7 are used to adjust the pressure on the plastic bags. The tension of the plastic bag is adjusted to ensure that it unfolds flat during the drying process. The heater 8 draws in external air through the suction pipe 12, and the generated hot air is introduced into the diversion pipe 10 through the exhaust pipe 9. The design of the diversion pipe 10 makes the hot air evenly distributed on the upper and lower sides of the drying chamber 4. The hot air is further sprayed out through the nozzle 11 installed on the diversion pipe 10 to form a uniform thermal environment and avoid local overheating or uneven drying. When the suction pipe 12 draws in external air, it is filtered through the filter box 13, and the gas is purified in stages.
[0021] Furthermore, a connecting pipe 14 is fixedly connected to the other side of the filter box 13; an installation plate 15 is installed at the opening of the filter box 13, and filter plate 16, filter plate 17, filter plate 18 and activated carbon plate 19 are installed sequentially from the outside to the inside on the lower surface of the installation plate 15.
[0022] During the drying process, external air enters the filter box 13 through the connecting pipe 14. After entering the filter box 13, the air passes through filter plate 16, filter plate 2 17 and filter plate 3 18 in sequence. These three filter plates are set with different pore sizes and materials to remove particulate matter and impurities in the air step by step, ensuring that large particles are initially intercepted and small and medium particles are further filtered, ultimately achieving fine purification of the gas.
[0023] Furthermore, the water-hanging assembly includes a collection box 20, the lower surface of which is mounted on one side of the upper surface of the base 1. The collection box 20 is positioned between the feeding roller frame 2 and the guide roller frame 3. Rotating rods 23 are rotatably connected to both sides of the upper part of the collection box 20. Connecting plates 24 are fixedly connected to adjacent ends of the rotating rods 23. Scrapers 25 are fixedly connected to one side of the adjacent surface of the connecting plates 24. A fixing frame 21 is fixedly connected to the other side of the middle of the upper surface of the base 1. A pressure roller 22 is rotatably connected to the upper part of the fixing frame 21. The pressure roller 22 is positioned above the collection box 20. Connecting rollers 5 are rotatably connected to the inlet and outlet of the drying box 4.
[0024] During the conveying process, the plastic bags first pass through the water-removing assembly. The water-removing assembly mechanically removes the moisture from the surface of the plastic bags by scraping the scraper 25 installed in the collection box 20. The design of the rotating rod 23 and the connecting plate 24 ensures that the scraper 25 fits tightly with the surface of the plastic bags. Excess moisture is collected in the collection box 20, which effectively reduces the moisture content before entering the drying stage, thereby shortening the drying time.
[0025] The working principle and usage process of this utility model: Plastic bags are evenly conveyed into the drying chamber 4 by the cooperation of the feeding roller frame 2 and the guide roller frame 3. The feeding roller frame 2 and the guide roller frame 3 ensure that the plastic bags are subjected to uniform force during conveying, avoiding deviation and uneven tension. During conveying, the plastic bags first pass through a water-removing component. The water-removing component mechanically removes moisture from the surface of the plastic bags using a scraper 25 installed in the collection box 20. The design of the rotating rod 23 and the connecting plate 24 ensures that the scraper 25 is in close contact with the surface of the plastic bags, and excess moisture is collected in the collection box 20. Then, the plastic bags undergo drying in the drying chamber 4. Inside the drying chamber 4, the tension of the plastic bags is adjusted by the upper tension roller 6 and the lower tension roller 7 to ensure that they unfold flat during the drying process. The heater 8 draws in external air through the suction pipe 12, and the generated hot air is introduced into the distribution pipe 10 through the exhaust pipe 9. The design of the distribution pipe 10 ensures that the hot air is evenly distributed on the upper and lower sides of the drying chamber 4. The hot air is further sprayed out through the nozzle 11 installed on the distribution pipe 10, forming a uniform thermal environment and avoiding local overheating or uneven drying. When the suction pipe 12 draws in external air, the air enters the filter box 13 through the connecting pipe 14. After entering the filter box 13, the air passes through the first filter plate 16, the second filter plate 17, and the third filter plate 18 in sequence. These three filter plates are set with different pore sizes and materials to remove particulate matter and impurities in the air step by step, ensuring that large particles are initially intercepted and small and medium particles are further filtered, ultimately achieving fine purification of the gas.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
