[0028] like Figures 1-4 As shown in the figure, an embodiment of the present invention proposes a woven bag color printing device, which includes a color printing chamber 1, a conveyor 2, woven bags 3, and slots 4. The conveyor 2 is fixedly installed at one end of the color printing chamber 1, and multiple woven bags 3 are installed at the top of the conveyor 2. The bags are conveyed into the interior of the color printing chamber 1 through the conveyor 2. Slots 4 are opened at both the front and rear ends of the color printing chamber 1. The conveyor 2 extends into the interior of the color printing chamber 1 from one end slot 4. A brush 5 is fixedly connected to the inner wall of one end of the color printing chamber 1, and a flattening guide roller 6 is arranged horizontally with the brush 5. The two ends of the flattening guide roller 6 are also connected to the inner wall of the color printing chamber 1 to form a stable support structure.

[0029] An ink inlet pipe 7 is movably installed at the top center of the color printing chamber 1. An ink cartridge 8 is movably installed at the bottom of the ink inlet pipe 7. The ink inlet pipe 7 is located at one end of the ink cartridge 8. Multiple ink nozzles 9 are evenly and equidistantly fixed at the bottom of the ink cartridge 8. An ink-absorbing sponge 10 is embedded and connected to the bottom of the ink cartridge 8. The multiple ink nozzles 9 are located inside the ink-absorbing sponge 10. The ink inlet pipe 7, ink cartridge 8, ink nozzles 9, and ink-absorbing sponge 10 are easy to replace, ensuring a stable ink supply during operation and improving the quality and efficiency of color printing. A piston is movably connected to the top of the ink inlet pipe 7. When the piston is open, ink is poured into the ink inlet pipe 7 and flows into the ink cartridge 8. When the ink flow rate inside the ink cartridge 8 reaches a certain amount, the piston blocks the ink inlet pipe 7 to prevent ink overflow. The ink flows through the multiple ink nozzles 9 inside the ink cartridge 8 to the ink-absorbing sponge 10. After the ink-absorbing sponge 10 evenly absorbs the ink, it accurately sprays the ink onto the surface of the woven bag 3 through the ink nozzles 9, ensuring that the color printed pattern is clear and uniform, improving the overall printing effect, and ensuring that the ink nozzles 9 spray ink evenly.

[0030] A first motor 11 is fixedly installed on the outside of one side of the color printing chamber 1. The output end of the first motor 11 passes through the end wall of the color printing chamber 1. A drive gear 12 is fixedly connected to the output end of the first motor 11. A driven gear 13 is connected to the top of the drive gear 12. The teeth of the drive gear 12 and the driven gear 13 are engaged with each other. A printing roller 14 is fixedly connected to the other end of the driven gear 13. The printing roller 14 is located below the ink-absorbing sponge 10. The bottom end face of the ink-absorbing sponge 10 is in contact with the circumferential surface of the printing roller 14.

[0031] The first motor 11 drives the drive gear 12 to rotate, and the teeth of the drive gear 12 drive the driven gear 13 to rotate. The printing roller 14 rotates with the driven gear 13. When the printing roller 14 passes under the ink-absorbing sponge 10, the ink-absorbing sponge 10 evenly applies ink to the woven bag 3 inside the printing roller 14 and ensures that the pattern on the surface of the woven bag 3 is clear. The woven bag 3 is sent into the color printing chamber 1 by the conveyor 2. The flattening guide roller 6 and the brush 5 work together to make the woven bag 3 flat and improve the printing effect. The first motor 11 drives the printing roller 14 to rotate, and the ink nozzle 9 accurately sprays ink at the bottom of the ink cartridge 8. The woven bag 3 passes smoothly through the color printing chamber 1 under the drive of the conveyor 2, and the pattern is accurately printed on the surface of the woven bag 3.

[0032] The printing roller 14 has a drying chamber 15 at its rear end. Multiple heating tubes 16 are fixedly installed at the top and bottom of the drying chamber 15. The heating tubes 16 are evenly distributed on the top of the drying chamber 15 to ensure that the material is heated evenly from top to bottom, thereby improving the printing quality. A ventilation opening is provided on one side of the drying chamber 15 to regulate the temperature and prevent the temperature inside the drying chamber 15 from overheating, ensuring that the temperature is constant during the printing process and improving the clarity and color saturation of the pattern.

[0033] A channel is provided in the middle of the inner cavity of the drying chamber 15, with a gap only wide enough for the woven bags 3 to pass through. The drying chamber 15 is connected to the printing roller 14, forming a smooth material channel. The woven bag material 3, which is conveyed from the color printing chamber 1, enters the cavity of the drying chamber 15 through the channel and is dried by the heating tube 16. The dried material is smoothly conveyed out through the slot 4 at the other end of the color printing chamber 1 to enter the next process. The high-temperature circulation system of the heating tube 16 effectively improves the drying efficiency, ensures uniform temperature distribution of the material during the drying process, thereby making the surface color of the material consistent, while reducing energy consumption and optimizing the overall production process. The woven bag 3 material, after being uniformly heated, is driven by the rotation of the drive gear 12 and the driven gear 13, which in turn drives the heated woven bag 3 to be rolled into the take-up roller 17. The take-up roller 17 is fixedly installed on the outside of the other end of the color printing chamber 1. There are fixed plates on both sides of the take-up roller 17. A second motor 18 is fixedly installed in the middle of the outside of one side of the fixed plate. The second motor 18 drives the take-up roller 17 to rotate, ensuring that the woven bag 3 is tightly rolled and preventing loosening. The second motor 18 can control the take-up roller 17 to adjust the winding force according to the thickness of the woven bag 3 to ensure uniform winding. The fixed plate makes it easy to control the take-up roller 17 to prevent it from deviating, ensuring a stable winding process and avoiding wrinkles in the material.
