Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The present invention provides a wood board inkjet printing device, such as Figure 1-Figure 4As shown, it includes a printing platform 15, a wooden board 1 is arranged on the printing platform 15, a printing system 14 is installed above the wooden board 1, the printing system 14 includes a printing component 1400, the printing component 1400 is driven by a driving component 13 to move horizontally, the printing component 1400 includes a printing module 1401, a prepress processor 1402 is installed on one side of the printing module 1401, a post-press processor 1403 is installed on the other side of the printing module 1401, a prepress heater 11 is installed at the bottom of the prepress processor 1402, and a post-press heater 12 is installed at the bottom of the post-press processor 1403. Through the carefully designed structure and component layout, efficient and high-quality inkjet printing of the wooden board is achieved. The printing platform 15 firmly supports the wooden board 1 to ensure stability during the printing process. Driven by the driving component 13, the printing system 14 and its printing component 1400 can accurately move horizontally, thereby achieving uniform and continuous printing of the wooden board 1. As the core part of the printing system, the printing module 1401 is responsible for accurately spraying ink onto the wooden board 1 to form a clear printing pattern. The addition of the pre-press processor 1402 and the post-press processor 1403 further improves the printing quality. The pre-press processor 1402 preheats the wooden board 1 through the pre-press heater 11 to reduce its surface humidity, making it easier to accept ink, thereby forming an area more suitable for printing. The post-press processor 1403 performs post-processing on the printed wooden board 1 through the post-press heater 12, and controls the depth of ink penetration by heating, making the color quality of the print more stable and lasting.

[0029] In this embodiment, a control system 20 is also installed outside the printing platform 15. The control system 20 includes a main control unit, which is the core of the control system and is responsible for receiving printing instructions from the outside (such as a computer) and parsing and processing them. The main control unit is also responsible for generating control signals to drive other components to perform corresponding operations.

[0030] The control system 20 also includes an input interface for receiving printing data and control signals sent by external devices (such as computers, scanners, etc.) After being processed by the input interface, these signals are transmitted to the main control unit for further processing.

[0031] The control system 20 also includes an output interface for transmitting the control signal generated by the main control unit to various components of the printing system 14 (such as the drive component 13, the prepress processor 1402, the postpress processor 1403, etc.) to achieve precise control of the printing process.

[0032] The control system 20 also includes a sensor interface, which is connected to various sensors (such as paper sensors, ink sensors, etc.) installed on the printing platform 15, and is used to monitor various parameters in the printing process (such as paper position, ink remaining amount, etc.) in real time, and feed this information back to the main control unit so as to adjust the printing strategy in time.

[0033] The control system 20 also includes a power management module, which is responsible for providing a stable power supply to the control system 20 and various components of the printing system 14 to ensure that the equipment can operate normally.

[0034] The control system 20 also includes a user interaction interface, such as a touch screen or a key panel, which allows the user to input printing parameters, view printing status, etc., thereby enhancing the usability and operability of the device.

[0035] Specifically, one side of the printing module 1401 is connected to an ink bottle 1430 via an ink tube 1432 , and an ink storage area 1431 is provided in the ink bottle 1430 for continuous ink supply.

[0036] Furthermore, the bottom of the printing module 1401 sprays ink onto the wooden board 1 through an inkjet head.

[0037] Furthermore, the input ends of the prepress processor 1402 and the postpress processor 1403 are both connected to the control system 20 through a circuit, the output end of the prepress processor 1402 is connected to the prepress heater 11 through a line, and the output end of the postpress processor 1403 is connected to the postpress heater 12 through a line. The input ends of the prepress processor 1402 and the postpress processor 1403 are both cleverly connected to the control system 20 through a circuit. This design realizes intelligent control of the prepress and postpress processing processes. After receiving instructions from the control system 20, the prepress processor 1402 can accurately control the switch and heating power of the prepress heater 11, thereby preheating the wooden board, reducing its surface humidity, and creating more ideal conditions for the subsequent printing process. The postpress processor 1403 is also connected to the postpress heater 12 through a line under the command of the control system 20 to post-process the printed wooden board. This step further controls the depth of ink penetration through heating to ensure that the color quality of the print is more stable and lasting.

[0038] In summary, this technical design not only improves the efficiency and quality of wood board inkjet printing, but also realizes fine management of the printing process through intelligent control, bringing significant progress and innovation to the wood board printing industry.

[0039] Furthermore, the driving component 13 includes a shell 131, a screw rod 132 is installed inside the shell 131, a screw rod slider 134 is installed on the screw rod 132, one end of the screw rod 132 is driven to rotate by a screw motor 133, one side of the screw rod slider 134 is connected to the printing component 1400 through a connecting shaft, the outer wall of the shell 131 is provided with a bar hole, and the connecting shaft on one side of the screw rod slider 134 is slidably matched with the bar hole, and a bracket 135 is installed at the bottom of the shell 131 to facilitate the movement of the printing component 1400 to achieve all-round printing of the wooden board 1.

[0040] Furthermore, the printing platform 15 includes a conveyor belt 151, and conveyor wheels 152 are installed at both ends of the conveyor belt 151. The conveyor wheels 152 are driven to rotate by a transmission motor, and auxiliary wheels are installed at equal intervals between the conveyor wheels 152 at both ends. The ends of the conveyor wheels 152 and the auxiliary wheels are installed on the bracket 135 through bearings to realize the horizontal movement of the wooden board 1. The movement direction of the wooden board 1 and the movement direction of the printing component 1400 are vertically set.

[0041] Furthermore, the printing step includes:

[0042] S1. Pre-treat the surface of the wood or cardboard by heating to reduce its surface humidity, making it easier to accept ink and forming an area suitable for printing;

[0043] S2. Printing pictures on the treated wood or cardboard surface;

[0044] S3. Post-process the printed wood or cardboard surface, control the depth of ink penetration by heating, and make the printed color quality stable.

[0045] Furthermore, the ink is water-based ink or weakly soluble ink, the heating power in the pre-treatment step can be adjusted according to the climate and the ambient temperature and humidity, and the heating power in the post-treatment step can also be adjusted according to the climate and the ambient temperature and humidity;

[0046] Further, the printing device moves at a speed of 1.2-1.7 m / s per second, and the heater is positioned 20 cm away from the nozzle to obtain an average heating time of 0.12-0.17 seconds.

[0047] First, by pre-treating the surface of the wood or cardboard, heating technology is used to effectively reduce its surface humidity, making the material more receptive to ink, thus forming an ideal printing area. This step lays a solid foundation for the subsequent printing process.

[0048] In the printing step S2, the required image is accurately printed on the surface of the processed wood board or paperboard, and both the clarity of the text and the fineness of the image have reached an extremely high level. This is due to the high-precision control of the printing system and the excellent performance of the ink.

[0049] Then, in step S3, the printed wood board or paperboard surface is post-processed. By heating again, the depth of ink penetration is accurately controlled, making the printed color quality more stable and effectively avoiding color deviation caused by uneven ink penetration.

[0050] It is worth mentioning that the ink in this embodiment uses water-based ink or weakly soluble ink, which has good permeability to the wood board and can further improve the printing quality. At the same time, the heating power in the pre-treatment and post-treatment steps can also be adjusted according to the climate and ambient temperature and humidity. This design enhances the adaptability and flexibility of the printing device, so that stable printing effects can be obtained in different environments.

[0051] Finally, the printing device moves at a speed of 1.2-1.7 m / s per second, and the heater is positioned 20 cm away from the nozzle. This precise setting enables the heater to provide an average heating time of 0.12-0.17 seconds, which ensures quick drying of the ink and avoids ink diffusion or color distortion due to overheating.

[0052] In summary, the wood board inkjet printing device and printing steps in this embodiment have demonstrated excellent technical effects, and have reached industry-leading levels in terms of printing speed, printing quality, and environmental adaptability.

[0053] Finally, it should be noted that the control system 20, prepress processor 1402, post-press processor 1403, etc. in this embodiment, the electronic components in the above components are all universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods.
