[0002] Inkjet printing technology is widely used in industrial production, playing a crucial role in the marking and traceability of products such as tires, pipes, and cylindrical workpieces. However, with the increasing level of industrial automation and the diversification of market demands, traditional inkjet printing equipment has gradually revealed many limitations.

[0003] Existing inkjet printing equipment typically employs a single inkjet terminal design, resulting in limited color printing and failing to meet the demands of modern industry for multi-color, high-precision coding. For instance, tire production often requires printing multiple colors of markings such as brand logos and specifications in different locations. Traditional equipment cannot achieve multi-color coding in the same process, leading to low production efficiency. Furthermore, the ink systems of existing inkjet printing equipment are prone to solidification at low temperatures, resulting in unstable coding quality. In addition, the curing speed after coding is also a key factor affecting production efficiency. Moreover, traditional equipment often uses natural air drying or ordinary heat curing methods, which have long curing times, making it difficult to meet the needs of high-speed production lines.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] An automated radial inkjet printing device, such as Figure 1As shown, the device includes a frame 1, a radial moving mechanism 2 on the frame 1, a lifting mechanism 3 that slides vertically on the radial moving mechanism 2, an inkjet box 4 on the lifting mechanism 3, a temperature control device 5 and several detachably connected coding blocks 6 inside the inkjet box 4, and several through holes 7 on the inkjet box 4 with the printheads of the coding blocks 6 aligned with the through holes 7. The frame 1 provides stable support for the entire device, ensuring that the components can cooperate precisely, improving the overall stability and reliability of the equipment. The radial moving mechanism 2 allows the printing blocks to move flexibly in the horizontal direction to adapt to workpieces of different sizes, improving the versatility of the equipment. The lifting mechanism 3 allows the inkjet box 4 to adjust its position in the vertical direction, ensuring accurate coding position and adapting to workpieces of different shapes and heights. By setting a temperature control device 5 inside the inkjet box 4, the ink is kept fluid in a low-temperature environment, avoiding the problem of reduced coding quality or printhead clogging caused by ink solidification. At the same time, since the coding blocks 6 are detachably connected, maintenance and replacement are convenient, improving the operability and service life of the equipment.

[0026] The lifting mechanism 3 is equipped with a retainer 8, on which the curing component 9 and the jetting component 10 are detachably connected. Specifically, the retainer 8 includes a horizontally arranged connecting rod 11 and two mounting blocks 12. The two mounting blocks 12 are both set on the connecting rod 11 and are located on both sides of the inkjet chamber 4. The curing component 9 and the jetting component 10 are respectively set on the two mounting blocks 12. The retainer 8 serves as a support structure for the curing component 9 and the jetting component 10, ensuring that they can be stably installed on both sides of the inkjet chamber 4, thereby improving the overall stability and reliability of the equipment. Furthermore, since the connecting rod 11 is horizontally arranged, it ensures that the positions of the curing component 9 and the jetting component 10 are symmetrical and balanced, avoiding equipment vibration or a decrease in coding accuracy due to a shift in the center of gravity. Moreover, both the curing component 9 and the jetting component 10 adopt a detachable connection method, which facilitates maintenance, replacement and upgrades, thereby reducing the operating cost of the equipment.

[0027] Specifically, the jet assembly 10 includes an air knife 13 for jetting compressed gas and a connecting block 14. The connecting block 14 is slidably connected to the moving block, and the air knife 13 is fixed to the connecting block 14 by bolts. The air knife 13, by jetting compressed gas, can effectively clean debris, dust, and oil stains from the workpiece surface, ensuring the cleanliness of the coding area and improving the yield and quality of coding. The sliding connection design between the connecting block 14 and the moving block allows the position of the air knife 13 to be flexibly adjusted according to the size and shape of the workpiece, improving the adaptability and versatility of the equipment. The bolt fixing method makes the installation and disassembly of the air knife 13 more convenient. Furthermore, the curing assembly... Component 9 includes a connecting plate 15 and a curing lamp 16 for curing ink. Specifically, the curing lamp 16 is a UV curing lamp 16. The two side walls of the connecting plate 15 are connected to the connecting block 14 and the curing lamp 16, respectively. By setting the UV curing lamp 16, it can emit ultraviolet light to cause the photosensitive resin in the ink to undergo a rapid polymerization reaction. The curing process can be completed in a few seconds or even milliseconds, so that the ink forms a uniform and firm cured layer on the surface of the workpiece. This avoids problems such as blurry or peeling of the inkjet printing caused by uneven curing, improves the adhesion and durability of the inkjet printing, and improves production efficiency. In addition, the UV curing lamp 16 has low energy consumption and long life.

[0028] The radial movement mechanism 2 includes a guide rail 17 and a drive motor 18. The guide rail 17 is horizontally mounted on the frame 1. The drive motor 18 drives the lifting mechanism 3 to move along the guide rail 17 via a lead screw. By setting the guide rail 17, which serves as a guide structure for radial movement, the lifting mechanism 3 can move smoothly horizontally, improving the accuracy of the coding position. The lead screw drive has the characteristics of high precision and high rigidity, enabling precise positioning of the lifting mechanism 3 and adapting to the coding requirements of workpieces of different sizes. The lifting mechanism 3 includes a vertically mounted slide rail 19 and a lifting motor 20. The lifting motor 20 drives the inkjet cartridge 4 to move up and down along the slide rail 19 via a synchronous belt lead screw. The slide rail 19 serves as a guide structure for the lifting motion, ensuring that the inkjet cartridge 4 can move up and down smoothly. The chain drive has the characteristics of strong load-bearing capacity and smooth transmission, suitable for the lifting motion of the inkjet cartridge 4, ensuring that the height of the inkjet head can be accurately adjusted to adapt to workpieces of different thicknesses and heights. Through the synergistic effect of the radial movement mechanism 2 and the lifting mechanism 3, high-precision positioning of the inkjet head in the horizontal and vertical directions is achieved, ensuring accurate coding position.

[0029] The constant temperature device 5 is an ink storage tank with an electric heating function. Each printhead is connected to the ink storage tank by a plug-in connection and the temperature is regulated by a temperature controller. The plug-in connection method facilitates quick installation, disassembly and replacement, reducing the difficulty of equipment maintenance. The constant temperature device 5 regulates the ink temperature in real time through electric heating elements and a temperature controller to ensure that the ink remains fluid in low-temperature environments, avoiding the problem of reduced coding quality or printhead clogging caused by ink solidification. It also ensures that the ink is sprayed evenly during the coding process, resulting in clear and firm coding effects, thus improving the marking quality of the product.

[0030] The frame 1 is also equipped with a control panel, which is electrically connected to the radial moving mechanism 2, the lifting mechanism 3, the constant temperature device 5, the curing component 9, and the jetting component 10. As the central control system of the equipment, the control panel integrates the control functions of the radial moving mechanism 2, the lifting mechanism 3, the constant temperature device 5, the curing component 9, and the jetting component 10, which simplifies the operation process and reduces the difficulty of operation. At the same time, the control panel realizes the automated control of each component, reduces manual intervention, and improves production efficiency and consistency.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
