Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inkjet printers, in particular to a dynamic drying and cooling integrated digital inkjet printer. BACKGROUND

[0002] A digital inkjet printer is a large computer peripheral output device that directly prints digital images on various soft or hard materials through micro-piezoelectric or thermal foaming inkjet technology. It is essentially a large color printer, but its format is larger and the carrier medium is no longer limited to paper. For example, the invention application with publication number CN108528064A discloses an inkjet printer, which includes a workbench, a nozzle, and a three-dimensional moving device. The three-dimensional moving device is used to drive the nozzle to move along the X, Y, and Z axes, respectively. It includes a first moving device, a second moving device, and a third moving device. The second moving device includes a mounting beam and a second power mechanism, and the third moving device includes a third power mechanism. The second moving device is driven by a linear motor, and the third moving device is driven by an electric translation table. Current inkjet printers do not have drying functions. After printing is completed, they are transferred to independent drying equipment for processing. This method is low in production efficiency and prone to picture quality problems such as ink stacking and bleeding. Therefore, integrated digital inkjet printers with drying and cooling functions have appeared. This drying method is called dynamic drying, which refers to the technology of instant and synchronous solidification or drying of ink immediately after it is sprayed onto the material surface, achieving the effect of printing and drying at the same time. However, current inkjet printers with dynamic drying and cooling integration still have the following defects: The drying method of current inkjet printers varies depending on the type of ink. When using uv ink, a curing lamp can be installed on the inkjet head trolley and moved along with it. When using traditional ink, hot air drying or infrared high-temperature drying is usually used. These drying structures have high temperatures and cannot be installed on the trolley. In addition, the timing requirements for cooling are different. When using uv ink, the curing and drying position is completed during ink spraying, and rapid cooling is required to prevent media deformation. When using traditional ink, heating and drying are performed after ink spraying, and cooling can be performed later. Therefore, current inkjet printers cannot meet the drying and cooling requirements of both uv ink and traditional ink, and have poor adaptability. In addition, during the drying process, the overall surface temperature distribution of the medium is uneven, which is often related to the ink spraying amount. During cooling, the same air volume is used for drying at each position, resulting in energy waste.

[0003] Therefore, we propose a dynamic drying and cooling integrated digital inkjet printer to solve the above problems. SUMMARY
