Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

As shown in Figure 1, the inkjet printing device in the utility model includes a printing part 1 and a platform part 2. The printing part 1 includes a guide rail beam and a printing carriage, and the printing carriage reciprocates along the direction of the guide rail beam (first axis) , and at the same time, the printing carriage can also make stepping motion along with the printing part 1 along the direction perpendicular to the first axis (Y axis). A nozzle for ejecting ink is installed on the printing carriage, an ink supply system for supplying ink to the nozzle and a control system for controlling ink supply and printing.

As shown in Figure 2, printing part 2 comprises printing platform 20, lifting mechanism 23 and guiding mechanism 24, and first paper guide roller 21 and second paper guide roller 22 are installed respectively at the front end and rear end of printing platform 20, first guide The paper roll 21 and the second paper guide roller 22 are parallel, and the first paper guide roller 21 and the second paper guide roller 22 are symmetrically arranged on the front end and the rear end of the printing platform 20, the first paper guide roller 21 and the second paper guide roller The central axis of 22 is parallel to the first axis. A plurality of suction holes are provided on the printing platform 20, and a suction device (not shown in the figure) is provided at the lower end of the printing platform 20. The function of the suction device is to generate a negative pressure between the surface of the platform and the medium to be printed. Therefore, the position of the medium to be printed on the printing platform 20 remains unchanged. The suction device in the utility model can adopt a suction pump, and also can install a plurality of suction fans at the lower end of the printing platform 20 . The printing platform 2 of the present utility model is installed on the base of the inkjet printing device through the lifting mechanism 23 .
