Description

Technical Field

[0001] This utility model relates to the field of digital printing machine technology, and more specifically, to a high-speed corrugated digital printing machine that efficiently utilizes an inkjet printing module. Background Technology

[0002] In the development of printing technology for heavy packaging materials such as corrugated cardboard and kraft paper, traditional corrugated machines, while effectively meeting the high-efficiency printing needs of large-area corrugated cardboard with wide-format printheads, have increasingly revealed their limitations. These wide-format printheads are often designed to maximize production efficiency, but in reality, corrugated cardboard varies greatly in size and shape, ranging from small convenience packages to large logistics boxes. Under such diverse demands, the application of a single wide-format printhead is quite cumbersome, especially when processing corrugated cardboard much smaller than the printhead's design capacity. In such cases, a large portion of the printhead remains idle, limiting the effective utilization of printhead resources and exacerbating production costs and resource waste.

[0003] Furthermore, the complex structure and high precision requirements of wide-format printheads result in high manufacturing costs. While such high costs are acceptable in the high-end printing equipment market, in broader market applications, such as small and medium-sized printing enterprises or industries particularly sensitive to cost control, the high cost of wide-format printheads undoubtedly increases the economic burden on enterprises and limits their popularization and promotion in these fields.

[0004] With the rapid development of digital printing technology, the market has placed higher demands on the flexibility, efficiency, and economy of printing equipment. Against this backdrop, improving the adaptability and utilization rate of printheads, and reducing the overall cost of equipment through technological innovation, have become hot topics and challenges in the corrugated printing field. Developing new printhead layout designs, such as detachable and merging printing modules, is one of the important directions proposed to solve these problems. Such designs can flexibly adjust printhead combinations according to actual printing needs, maximizing the utilization of each printhead resource and reducing idle waste. At the same time, the modular design approach can effectively control production costs and promote the widespread application and upgrading of technology.

[0005] In conclusion, addressing the issues of low printhead utilization and high equipment costs in printing on materials such as corrugated cardboard and kraft paper, technological innovation and design optimization can not only improve printing efficiency and flexibility but also effectively reduce production costs, thus promoting the sustainable development of the corrugated printing industry.

[0036] Figure 13 This is a schematic diagram of the second inkjet printing module structure of this utility model patent.

[0037] The components include: conveyor belt 100, first inkjet printing module 210, second inkjet printing module 220, lifting mechanism 300, translation mechanism 400, waste ink recycling mechanism 500, main ink cartridge 600, paper feeding mechanism 700, slide rail 410, conveyor roller 710, first tray 211, second tray 221, printhead 212, and auxiliary ink cartridge 223. Detailed Implementation

[0038] This utility model utilizes a high-efficiency high-speed corrugated digital printing machine, such as... Figure 9 As shown, the main components include a conveyor belt 100, a first inkjet printing module 210, a second inkjet printing module 220, a lifting mechanism 300, a translation mechanism 400, a waste ink recycling mechanism 500, a main ink cartridge 600, and a paper feeding mechanism 700. The conveyor belt 100 transports the corrugated cardboard to be printed to the printing area, while the paper feeding mechanism 700 accurately places the corrugated cardboard onto the conveyor belt 100.

[0039] like Figure 10 and Figure 11As shown, the first printing module 210 and the second printing module 220 are respectively installed on both sides of the translation mechanism 400, and can move horizontally through the slide rail 410. Each module includes an independent printhead bracket (such as the first tray 211 and the second tray 221), on which a high-precision printhead assembly (such as the printhead 212) is installed for ink jetting for printing.

[0040] When it is necessary to print on both sides of the corrugated cardboard separately, the control system controls the translation mechanism 400 to move the first printing module 210 and the second printing module 220 to the two sides of the corrugated cardboard respectively, so that the printing operation can be performed independently. Figure 12 and 13 It can be seen that the first tray 211 and the second tray 221 have an interleaved and complementary structure. This structural design can save the most printheads 212 while ensuring that a single first printing module 210 or second printing module 220 has the maximum printing area.

[0041] If printing is required on the center of the corrugated cardboard or for full-width printing, the control system drives the translation mechanism 400 to bring the two printing modules closer together and merge them to complete the printing task. Figure 11 As shown. When the first printing module 210 and the second printing module 220 are in a combined working state, the first tray 211 and the second tray 221 will be relatively close, but not simply aligned. Instead, they are designed to be staggered at a certain distance, so that the multiple sets of printheads 212 mounted on their respective supports can form complementary spraying areas.

[0042] Traditional aligned printheads can create blind spots, meaning some areas may not be fully printed due to insufficient printhead coverage. Staggered printing effectively reduces or eliminates these blind spots, ensuring comprehensive and uniform printing on the corrugated board surface. Certain areas of corrugated board may require higher printing resolution or richer color gradations. Through staggered design, the spray density and color configuration of different printheads can be adjusted according to actual needs, achieving optimized resource allocation and efficient utilization.

[0043] In this invention, the first tray 211 and the second tray 221, through an alternating arrangement and the complementarity between multiple sets of printheads, achieve efficient utilization of printhead resources and a significant improvement in printing quality. This design not only improves printing accuracy and consistency but also enhances the flexibility and adaptability of the printing press, enabling it to meet various complex and diverse corrugated board printing needs.

[0044] The module drive mechanism consists of linear guides and a drive motor. By precisely controlling the motor's speed and direction, it achieves precise movement of the printing module. The control system integrates advanced algorithms and sensors, capable of receiving user-inputted corrugated cardboard dimensions and printing requirements, and automatically calculating and adjusting the module's position and operating status.
