[0002] Printing is a technology that uses processes such as plate making, inking, and pressing to transfer ink to the surface of materials such as paper, textiles, and leather to reproduce the content of the original manuscript in batches.
[0003] When printing on paper packaging bags, a printing press is required. However, some existing printing presses usually print directly on the packaging bags without treating the dust on the surface of the bags. As a result, dust remains on the printing area during later printing, which then adheres to the printing ink and affects the printing effect.
[0004] To address the aforementioned issues, a packaging bag printing machine with a cooling function is proposed. Utility Model Content

[0024] 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.
[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.
[0026] Please see Figure 1-4 This utility model provides a technical solution: a packaging bag printing machine with cooling function, including a workbench 1, a support 3 on the top of the workbench 1, a transmission belt 2 inside the support 3, a printing machine body 11 on the support 3, mounting plates 15 fixedly installed on both sides of the support 3, a motor bracket 14 fixedly installed on one side of the mounting plate 15, a motor 13 fixedly installed on one end of the motor bracket 14, a first rotating shaft 16 fixedly installed at the output end of the motor 13, the first rotating shaft 16 rotatably passes through the two mounting plates 15 and is rotatably connected to the two mounting plates 15, and a cleaning roller 4 is fixedly sleeved on the surface of the first rotating shaft 16.
[0027] When cleaning the packaging bags, the motor 13 is started, which drives the first rotating shaft 16 to rotate, thereby causing the cleaning roller 4 to rotate. The cleaning roller 4 then cleans the surface of the packaging bags on the transmission belt 2, thereby preventing the accumulation of impurities on the packaging bags and preventing them from interfering with the printing process when passing through the printing press body 11, thus improving the appearance of the printed product.
[0028] A second rotating shaft 17 is rotatably connected inside the mounting plate 15. A suction fan housing 5 is fixedly installed between the two mounting plates 15. The second rotating shaft 17 rotates through the suction fan housing 5 and extends into the interior of the suction fan housing 5. A blade 20 is fixedly installed on one end of the second rotating shaft 17 that extends into the interior of the suction fan housing 5. The blade 20 is rotatably connected inside the suction fan housing 5. Pulleys 18 are fixedly sleeved on both the first rotating shaft 16 and the second rotating shaft 17. A belt 19 is connected to the upper side of the two pulleys 18. A fixing plate 12 is fixedly installed on one side of the bracket 3. A water tank 7 is fixedly installed on the top of the fixing plate 12. A first connecting pipe 6 connects the suction fan housing 5 and the water tank 7. One end of the first connecting pipe 6 extends into the interior of the water tank 7 and extends to the bottom of the water tank 7. A second air nozzle 21 is fixedly connected to one end of the first connecting pipe 6 that extends into the interior of the water tank 7. The second air nozzle 21 is connected to the first connecting pipe 6.
[0029] When the first rotating shaft 16 rotates, it drives the second rotating shaft 17 to rotate through the two pulleys 18 and the belt 19, which in turn causes the blades 20 to rotate. This draws the cleaned dust into the inside of the suction fan housing 5 and transports it to the inside of the water tank 7 through the first connecting pipe 6. The water inside the water tank 7 overflows the second air outlet nozzle 21 and is then discharged through the second air outlet nozzle 21. Through the contact between water and air, impurities in the air are carried away by the water, which facilitates the treatment of dust. This minimizes the amount of dust that may be discharged into the water tank 7, reduces dust in the air, and also reduces dust on the packaging bag, preventing dust interference during printing.
[0030] The second air nozzle 21 facilitates the dispersion of air in the water, thereby enabling thorough treatment of dust in the air.
[0031] The upper end of the water tank 7 is connected to the second connecting pipe 8. The support frame 9 is fixedly installed on the bracket 3. The bottom of the support frame 9 is fixedly connected to the first air outlet nozzle 10. The end of the second connecting pipe 8 away from the water tank 7 is connected to the first air outlet nozzle 10. A filter screen 22 is fixedly installed at the connection between the second connecting pipe 8 and the water tank 7.
[0032] When air enters the second connecting pipe 8, it is filtered again by the filter screen 22 to remove impurities. Then, the air is sprayed out through the first air nozzle 10. The sprayed air is cooled by water, which helps to cool the packaging bag and the printing part. The air cooling the packaging bag is also handled to prevent dust from adhering to the printing part and to ensure the appearance of the printing.
[0033] Working principle:
[0034] The motor 13 is started, causing the first rotating shaft 16 to rotate, which in turn causes the cleaning roller 4 to rotate. The cleaning roller 4 then cleans the surface of the packaging bag on the transmission belt 2, thus preventing the accumulation of impurities on the packaging bag. When the first rotating shaft 16 rotates, it drives the second rotating shaft 17 to rotate through the two pulleys 18 and the belt 19, which in turn causes the blades 20 to rotate. This sucks the cleaned dust into the inside of the suction fan housing 5 and delivers it to the inside of the water tank 7 through the first connecting pipe 6. The water in the water tank 7 overflows the second air outlet nozzle 21 and is then discharged through the second air outlet nozzle 21. Through the contact between water and air, impurities in the air are carried away by the water, thus facilitating the treatment of dust.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
