[0023] like Figures 1-4 As shown, it illustrates a printing apparatus for producing plastic packaging bags according to an embodiment of the present invention, including a printing apparatus body 1, a printing roller frame 6 mounted on the top of the printing apparatus body 1, and further comprising: Protective component 2 is installed on the top of the printing device body 1. A ventilation component 3 is installed on the side of the protective component 2. A static elimination component 4 is installed at one end of the protective component 2. An adaptive adjustment component 5 is installed on the printing roller frame 6. The protective component 2 includes a protective cover 21. Mounting blocks 22 are fixed on both sides of the protective cover 21. Fixing nuts 23 are threaded onto the mounting blocks 22. The mounting blocks 22 are threaded onto the top sides of the printing device body 1. A transparent glass window 24 is fixed on the side of the protective cover 21 near the ventilation component 3. A material inlet 25 is located on the side of the protective cover 21.

[0024] In this example, protective component 2 is used to prevent dust in the air from contaminating the plastic packaging bag during the printing process, which could lead to poor pattern quality on the printed plastic packaging bag and thus affect the final quality of the plastic packaging bag.

[0025] In some examples, the ventilation assembly 3 includes a suction pump 31 with a suction port 32 on its side. A connecting pipe 33 is fixed to the side of the suction pump 31 near the protective cover 21, and an air intake fan 36 is fixed to the side of the connecting pipe 33 near the protective cover 21.

[0026] In this example, the ventilation component 3 is used to ensure that all air entering the protective cover 21 is filtered, thereby keeping the inside of the protective cover 21 clean.

[0027] In some examples, a mounting housing 34 is movably mounted on the side of the connecting pipe 33, and an air filter 35 is fixed inside the mounting housing 34.

[0028] In this example, the air filter 35 is used to filter the air drawn out by the suction pump 31. The mounting housing 34 allows the air filter 35 to be disassembled for cleaning after long-term use, so that the air filter 35 can be used for a long time.

[0029] In some examples, the static elimination component 4 includes a mounting plate 41, which is mounted on top of the inlet 25. An upper ionizing air bar 42 is fixed to the bottom of the mounting plate 41, and a connecting wire 43 is fixed to the side of the upper ionizing air bar 42.

[0030] In this example, the static elimination component 4 enables static elimination treatment on the surface of the plastic packaging bag, thereby allowing dust and other particles on the surface of the plastic packaging bag to be cleaned.

[0031] In some examples, a first motor 44 is installed on the top of the printing device body 1, a lifting screw 45 is fixed to the output end of the first motor 44, a lifting block 46 is threaded onto the lifting screw 45, a lower ion air bar 47 is installed on the side of the lifting block 46, a lifting groove 48 is opened on the inner wall of the printing device body 1, and the lifting screw 45 is rotatably connected in the lifting groove 48.

[0032] In this example, the lower ionizer 47 can be adjusted by raising the lifting screw 45, thereby controlling the distance between the lower ionizer 47 and the bottom surface of the plastic packaging bag.

[0033] For example, such as Figure 3As shown, when printing on plastic packaging bags using the printing device body 1 and printing roller 6, the protective cover 21 is first installed on the outside of the printing roller 6 on top of the printing device body 1 via the mounting block 22, and the protective cover 21 is threadedly fixed by the fixing nut 23, so that the protective cover 21 can be stably installed on the top of the printing device body 1. Then, when the plastic packaging bag enters the protective cover 21 through the feed port 25, the first motor 44 controlled by the PLC drives the lifting screw 45 to rotate, so that the lifting block 46 on the lifting screw 45 drives the lower ion air bar 47 to move up and down, so that the lower ion air bar 47 can fit more closely to the surface of the plastic packaging bag, and the mounting plate 41 and the lower ion air bar 47 simultaneously apply pressure to the plastic packaging bag. The upper and lower surfaces of the plastic packaging bag are electrostatically eliminated, ensuring the bag remains clean during printing on the printing roller 6 while it enters the protective cover 21. Simultaneously, a PLC-controlled suction pump 31 draws air through the suction port 32, which flows into the connecting pipe 33. The air is then filtered by an air filter 35 installed in the connecting pipe 33, ensuring the air entering the protective cover 21 is clean and free of impurities. After prolonged use, the mounting shell 34 can be pulled out, allowing the air filter 35 to be removed from the connecting pipe 33 for regular cleaning and replacement, thus ensuring the longevity of the air filter 35.

[0034] like Figures 1-5 As shown, on the other hand, this utility model also provides a printing device for producing plastic packaging bags, including an adaptive adjustment component 5. The adaptive adjustment component 5 includes a second motor 51, which is installed on the inner wall of the printing roller frame 6. A rotating shaft block 52 is fixed at the output end of the second motor 51, and a cylinder 53 is fixed at the bottom of the rotating shaft block 52. A scraper 54 is fixed at the other end of the cylinder 53.

[0035] In this example, the adaptive adjustment component 5 prevents the blade 54 from being damaged by hard objects in the ink when scraping the printing roller 6, allowing the blade 54 to extend and retract freely, and the tilt angle of the blade 54 can be adjusted within a certain range.

[0036] In some examples, support blocks 56 are fixed on both sides of the bottom of the printing roller holder 6, the rotating shaft block 52 is rotatably connected in the support block 56, the printing roller holder 6 has an installation groove 57 on the inner side, and the second motor 51 is installed on the inner wall of the installation groove 57.

[0037] In this example, the support block 56 is used to support the rotating shaft block 52.

[0038] In some examples, a spring telescopic rod 55 is fixed between the rotating shaft block 52 and the scraper 54. Several sets of spring telescopic rods 55 are provided, and the sets of spring telescopic rods 55 are symmetrically distributed on both sides of the cylinder 53.

[0039] In this example, the spring telescopic rod 55 allows the scraper 54 to retract when it comes into contact with a hard object, while the cylinder 53 allows the scraper 54 to be precisely adjusted to fit against the surface of the printing roller.

[0040] For example, such as Figure 5 As shown, firstly, depending on the actual printing roller holder 6 installed, the second motor 51 controlled by the PLC can drive the rotating shaft block 52 to rotate inside the support block 56, thereby allowing the rotating shaft block 52 to drive the scraper 54 to tilt, so that the scraper 54 can change the tilt angle within a certain range. Then, the cylinder 53 controlled by the PLC makes the blade of the scraper 54 fit against the surface of the printing roller holder 6, so that the scraper 54 can better scrape off the ink on the surface of the printing roller holder 6. When the scraper 54 touches a hard object during the scraping process, the scraper 54 can be retracted by the spring telescopic rod 55 to avoid hard contact between the scraper 54 and the hard object, thereby preventing damage to the scraper 54.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
