[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] Reference Figure 1-4 An automatic gravure roller ink-spraying mechanism includes an ink-spraying cartridge 1. The provision of an ink-spraying cartridge cover 2 not only protects the cartridge 1 from external impurities during the ink-spraying process, but also provides a convenient way to open it when cleaning or replacing the paint is necessary. This openable and closable design enhances the flexibility and maintainability of the device. The ink-spraying cartridge cover 2 is provided on one side of the ink-spraying cartridge 1, and an ink basin 4 is provided below the ink-spraying cartridge 1. A pipe is provided between the inner cavities of the ink-spraying cartridge 1 and the inner cavities of the ink basin 4. The pipe serves as a bridge connecting the ink-spraying cartridge 1 and the ink basin 4, enabling automatic paint delivery. Through the design of the pipeline, the paint can be stably and continuously transported from the ink basin 4 to the ink shower box 1, providing the necessary paint supply for the ink shower process and ensuring the continuity and uniformity of the ink shower. A suction port is provided at the bottom of the ink shower box 1, and the inner cavity of the suction port is fixedly connected to a section of the outer ring of the pipeline. A gravure roller 3 is provided below the ink shower box 1 and above the ink basin 4. An ultrasonic liquid level protection switch 6 is provided on one side of the ink basin 4. A storage barrel 5 is provided on one side of the ink shower box 1. A liquid inlet mechanism 8 is provided on one side of the storage barrel 5. A number of spray through holes are provided at the bottom of the inner cavity of the ink shower box 1.

[0023] Furthermore, liquid inlet mechanism 8 includes connecting tube 1, connecting tube 2, and a pump. The pump's input end is fixedly connected to one end of connecting tube 1, and the other end of connecting tube 1 communicates with the inner cavity of ink basin 4. The pump's output end is fixedly connected to one end of connecting tube 2, and the other end of connecting tube 2 communicates with the inner cavity of material storage barrel 5. Connecting tube 1 connects ink basin 4 to the pump, which then draws paint from material storage barrel 5 and delivers it to ink basin 4 through connecting tube 2. This process achieves automatic paint supply, avoids the tedious manual addition process, improves production efficiency, reduces paint overflow or shortage due to human error, and ensures continuous and stable printing.

[0024] Furthermore, the bottom side of the ink shower box cover 2 is rotatably connected to the top side of the ink shower box 1 via a hinge. The ink shower box cover 2 can be easily opened via the hinge, allowing operators to easily access the interior of the ink shower box for cleaning or replacing the coating. This design improves the maintainability of the equipment, ensures the accuracy of ink dispensing and the cleanliness of the coating, and thus guarantees printing quality.

[0025] Furthermore, a valve is installed on the outer ring of the pipe, and the inner cavity of the pipe is connected to the inner cavity of the ink spraying box 1. The valve can adjust the flow rate of the paint in the pipe, thereby accurately controlling the amount of paint sprayed onto the gravure roller 3. This setting avoids paint waste, ensures the uniformity and consistency of ink spraying, and improves printing quality.

[0026] Furthermore, the gravure roller 3 is located directly below the ink spraying box 1. Its two ends are rotatably connected to one side of the adjacent bracket via a rotating shaft. The stable rotation and precise positioning of the gravure roller 3 enable the ink spraying box 1 to evenly apply the coating to its surface. This design improves the accuracy and stability of the ink spraying process, meeting the requirements of high-precision printing.

[0027] Furthermore, the input end of the ultrasonic liquid level protection switch 6 is fixedly connected to a liquid level sensor probe, which is located in the inner cavity of the ink basin 4. A return mechanism 7 is provided on one side of the ink basin 4. The return mechanism 7 includes a collection tank. Several collection tanks are opened at the bottom of the inner cavity of the ink basin 4. The liquid level sensor probe monitors the paint level in the ink basin 4 in real time. Once the preset value is reached, the ultrasonic liquid level protection switch 6 is triggered to stop the liquid from entering. At the same time, the collection tank in the return mechanism 7 can collect excess paint or waste for recycling or disposal. This arrangement reduces paint waste and environmental pollution, reducing production costs and environmental risks.

[0028] In summary: Paint supply: Through the operation of the pump of the liquid inlet mechanism 8, the paint in the storage barrel 5 is extracted and pressurized through the connecting pipe 2, and then transported to the ink basin 4 through the connecting pipe 1. This process realizes the automatic supply of paint, reduces manual intervention, and improves production efficiency.

[0029] Liquid level control: The liquid level sensor probe of the ultrasonic liquid level protection switch 6 monitors the paint liquid level in the ink basin 4 in real time. When the liquid level reaches the preset value, the switch is automatically triggered, and the solenoid valve is controlled to close the pump of the liquid inlet mechanism 8, stopping the paint supply, preventing paint overflow, ensuring production safety and saving paint.

[0030] Ink spraying: During the ink spraying process, ink spraying box 1 draws an appropriate amount of paint from ink basin 4 through the suction port at its bottom and transfers it to the interior of the ink spraying box through a pipe. The paint is then evenly sprayed onto the surface of gravure roller 3 located directly below ink spraying box 1. The rotation of gravure roller 3 ensures that the paint is evenly applied to its surface, improving print quality.

[0031] Cleaning and Maintenance: When cleaning or replacing the paint is required, the ink spray box cover 2 can be opened by hinges, allowing the operator to enter the ink spray box for cleaning. This design improves the maintainability of the equipment and ensures the accuracy of ink spraying and the cleanliness of the paint.

[0032] Waste disposal: Excess paint or waste will fall into the collection tank at the bottom of the ink basin 4, and will be collected and recycled or processed by the return mechanism 7. This setting reduces paint waste and environmental pollution, reducing production costs and environmental risks.

[0033] The liquid inlet mechanism 8 and ultrasonic liquid level protection switch 6 enable automatic paint supply and liquid level control, reducing manual intervention and improving production efficiency. The precise coordination between the ink dispenser and the gravure roller 3, as well as the uniform application of paint, ensures consistent thickness of the printed layer and high print quality. The retractable design of the ink dispenser cover 2 simplifies cleaning and maintenance, improving the maintainability and service life of the equipment. The return mechanism 7 collects and recycles waste materials, reducing paint waste and environmental pollution. The valves on the pipeline allow for precise control of the ink dispenser volume, avoiding paint waste and unnecessary costs.

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
