[0002] Product label color printing equipment is the core equipment in modern packaging and labeling production. Its main function is to endow product labels with strong visual appeal and information carrying capacity through high-precision and high-efficiency color printing technology. It can clearly present key information such as brand logo, product image, detailed description, ingredient list, barcode, QR code and anti-counterfeiting mark.

[0003] While existing color printing technologies for product labels can achieve basic ink transfer and pattern formation, traditional printing equipment has shortcomings in the drying process. Most of these devices use static drying, where the printed substrate is dried by hot air within a fixed drying area. However, this method is inefficient because the heat source cannot be evenly applied to the upper and lower surfaces of the substrate, resulting in uneven drying and even incomplete drying in some areas, which reduces the overall printing efficiency. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 - Figure 5This utility model provides an embodiment of a color printing device for product labels, including a platform 1 for supporting the substrate and legs 2 supporting the platform 1. A printing execution module is provided on the platform 1, comprising an ink storage tank 3, a feed pump 4, a jetting unit, and vertically distributed, parallel double printing roller assemblies. The feed pump 4 forms a sealed connection with the ink storage tank 3 through a flexible guide pipe. The jetting unit receives the ink output from the feed pump 4 and performs directional jetting dispersion. The double printing roller assembly is used to perform bidirectional imprinting on the surface of the substrate treated by the jetting unit. A drying module is also provided on the platform 1, comprising an independently set support 5. A linear displacement drive mechanism is provided on the support 5. A cooperative sliding mechanism is also provided on the platform 1, linked to the linear displacement drive mechanism. The linear displacement drive mechanism and the cooperative sliding mechanism are jointly equipped with a heat application component that can move synchronously with them. The heat application component performs dynamic heat radiation treatment on the printed substrate. The platform 1 serves as the basic platform for printing operations, supporting the substrate to be printed. The printing execution module is responsible for accurately transferring ink to the substrate to form the desired pattern or text. The ink storage tank 3 is used to store the ink used for printing. The required ink supply is ensured to be stable and continuous. The feed pump 4 forms a sealed connection with the ink storage tank 3 through a flexible guide pipe, which is responsible for drawing the ink from the storage tank and delivering it to the spraying unit. The spraying unit receives the ink output by the feed pump 4 and sprays the ink in a directional manner onto the substrate to form a preliminary printing pattern. The dual printing roller assembly is used to perform bidirectional embossing on the surface of the substrate treated by the spraying unit. By adjusting the pressure and speed of the printing rollers, the distribution and thickness of the ink on the substrate can be controlled, thereby obtaining a clear printing effect. The drying module is used to perform heat radiation treatment on the printed substrate to accelerate the drying and curing process of the ink, improve printing quality and efficiency. The linear displacement drive mechanism is set on the bracket 5 and is responsible for driving the heat energy application component to move linearly. The coordinated sliding mechanism is linked with the linear displacement drive mechanism to ensure that the heat energy application component remains stable and synchronous during the movement. The heat energy application component is mounted on the linear displacement drive mechanism and the coordinated sliding mechanism and can move synchronously with them. The heat energy application component performs dynamic heat radiation treatment on the printed substrate by emitting heat energy (such as infrared radiation) to accelerate the drying and curing of the ink.

[0022] Please see Figure 3 - Figure 4In this embodiment, the dual printing roller assembly includes a gantry 6 mounted on a platform 1. Vertically distributed drive rollers 7 and driven rollers 8 are arranged within the gantry 6. A servo motor 9 is mounted on one outer wall of the gantry 6, and the output shaft of the servo motor 9 is connected to one end of the drive roller 7. A linkage structure is provided between the drive roller 7 and the driven roller 8. The linkage structure includes a drive gear 10 mounted on the outer wall of the drive roller 7 and a driven gear 11 mounted on the outer wall of the driven roller 8. The drive gear 10 and the driven gear 11 are meshed together. The spraying unit includes a support plate 12 mounted on the gantry 6. A retaining ring 13 is provided on the surface of the support plate 12. A feed pipe 14 passes through the retaining ring 13. A nozzle 15 is provided at the outlet of the feed pipe 14. The inlet of the feed pipe 14 is connected to the outlet port of the feed pump 4 via a flexible guide pipe. The dual printing roller assembly is used to process printed rollers... The substrate surface treated by the jetting unit is subjected to bidirectional embossing to ensure that the ink adheres evenly and firmly to the substrate. The gantry 6 provides stable support and positioning for the printing roller. The drive roller 7 and the driven roller 8 achieve synchronous rotation through a linkage structure. The drive roller 7 is driven by the servo motor 9 to provide the power required for printing. The linkage structure includes a drive gear 10 and a driven gear 11, which mesh to achieve synchronous rotation of the drive roller 7 and the driven roller 8. The jetting unit is responsible for accurately jetting the ink onto the substrate. The support plate 12 provides stable support for the feed tube 14. The retaining ring 13 is used to fix the feed tube 14 to prevent it from shaking or deviating during the jetting process. The nozzle 15 is used to jet the ink onto the substrate. The feed port of the feed tube 14 is connected to the discharge port of the feed pump 4 through a flexible guide pipe to ensure a stable supply of ink.

[0023] Please see Figure 2 and Figure 5In this embodiment, the linear displacement drive mechanism includes a U-shaped frame 16 disposed on the upper surface of the support 5. A rotary motor 17 is disposed on the outer wall of the U-shaped frame 16. A reciprocating lead screw 18 connected to the output shaft of the rotary motor 17 is disposed inside the U-shaped frame 16. A movable seat 19 is disposed on the outer wall of the reciprocating lead screw 18. The cooperative sliding mechanism includes a groove 20 formed on the table 1. A guide rail 21 is disposed at the bottom of the groove 20. A slider 22 is slidably connected to the guide rail 21. The heat energy application component includes an active heating seat 23 disposed at the lower end of the movable seat 19. A driven heating seat 24 is disposed at the upper end of the slider 22. A linkage rod 25 is fixedly connected between the active heating seat 23 and the driven heating seat 24. The U-shaped frame 16 provides stable support and positioning for the reciprocating lead screw 18 and the rotary motor 17. The rotary motor 17 drives the reciprocating lead screw 18 to rotate. When the rotary motor 17 drives the reciprocating screw 18 to rotate, the moving seat 19 moves linearly along the reciprocating screw 18. The guide rail 21 is set at the bottom of the groove 20 to provide a sliding track for the slider 22. The slider 22 is slidably connected to the guide rail 21, and its upper end is connected to the driven heating seat 24, realizing the synchronous movement of the driven heating seat 24 and the active heating seat 23. The heat energy application component performs dynamic heat radiation treatment on the printed substrate, accelerating the drying and curing process of the ink. The active heating seat 23 moves with the linear movement of the moving seat 19 to perform heat radiation treatment on the upper surface of the substrate. The driven heating seat 24 is set at the upper end of the slider 22 and is fixed to the active heating seat 23 through the linkage rod 25, realizing the synchronous movement with the active heating seat 23, thereby performing heat radiation treatment on the lower surface of the substrate.

[0024] Working principle: First, the substrate to be printed is placed on the table 1 to ensure that the substrate is stable and accurately positioned. Then, the ink in the ink storage tank 3 is stably delivered to the spraying unit through the feed pump 4 and the flexible guide pipe. The nozzle 15 of the spraying unit, fixed by the support plate 12 and the retaining ring 13, accurately sprays and disperses the ink onto the substrate to form a preliminary printing pattern. Subsequently, the dual printing roller assembly starts to work. The active roller 7 is driven by the servo motor 9 and is connected by the active gear 10 and the driven gear 11 in the linkage structure to drive the driven roller 8 to rotate synchronously. The dual printing rollers perform bidirectional pressure printing on the surface of the substrate treated by the spraying unit. By adjusting the pressure and speed of the printing rollers, it is ensured that the ink is evenly and firmly attached to the substrate to form a clear printing effect.

[0025] Next, the drying process begins. The rotary motor 17 in the linear displacement drive mechanism starts, driving the reciprocating lead screw 18 to rotate, causing the moving seat 19 to move linearly along the reciprocating lead screw 18. At the same time, the slider 22 in the cooperative sliding mechanism slides on the guide rail 21, moving synchronously with the moving seat 19. The active heating seat 23 of the heat energy application component performs dynamic heat radiation treatment on the upper surface of the substrate as the moving seat 19 moves. The driven heating seat 24 is fixed to the active heating seat 23 through the linkage rod 25, moves synchronously, and performs heat radiation treatment on the lower surface of the substrate. In this way, the heat energy application component performs comprehensive dynamic heat radiation treatment on the printed substrate, accelerating the drying and curing process of the ink and improving printing quality and efficiency.

[0026] Through the above steps, the dual printing roller assembly ensures uniform ink distribution and precise thickness control. The integrated drying module uses dynamic heat radiation treatment, which is more efficient than static drying, accelerates ink drying and curing, shortens the production cycle, and improves printing efficiency. This solves the problem that the static hot air drying method used in traditional printing equipment leads to uneven drying of the upper and lower surfaces of the substrate, which reduces the overall printing efficiency.
