[0028] The inkjet control console 23 is used to control the operation and idleness of multiple inkjet devices 3. The inkjet plate 27 can move up and down, thereby driving the inkjet device 3 on the surface of the inkjet plate 27 to move up and down. When facing papers of different thicknesses, the distance between the nozzle and the surface of the printed object can be adjusted and maintained. An ink tank 31 for storing ink is installed at the top of the inner part of the inkjet device 3. The ink can be transported through multiple ink supply tubes 33 at the lower end of the ink tank 31 and finally sprayed out through the inkjet head 34. In use, multiple printing papers 43 can be put into the feeding area 4 and sent to the conveyor belt 17 in the conveying platform 1 by the paper sheet separation device for transportation one by one. When transporting the paper, the printing paper 43 can be pushed to the surface of the second sensor head 45 and the first sensor head 44 by the first push rod 41. By setting the first sensor head 44 and the second sensor head 45, it can be avoided that the corners of the paper are skewed during the pushing, triggering the detection distance to return to zero in advance.

[0035] Reference Figure 2 The electric lifting seat 26 is installed inside the side plate 28, and the side end of the electric lifting seat 26 is fixedly connected with the inkjet plate 27. The electric lifting seat 26 can drive the inkjet plate 27 to move up and down, and then drive the inkjet device 3 on the surface of the inkjet plate 27 to move up and down.

The slide rod 15 can improve the stability of the adjustment area 2 when it moves.

[0037] Reference Figure 1The front end of the transmission platform 1 is fixedly connected with a discharge box 19, the transmission platform 1 is rotatably connected with a transmission roller 16, the surface of the transmission roller 16 is sleeved with a transmission belt 17, and the inside of the transmission platform 1 and the inner side end of the transmission belt 17 are fixedly connected with a pad 18.

[0038] Working principle: Rotating the transmission roller 16 can drive the transmission belt 17 to rotate, thereby transporting the printed material, and the discharge box 19 is used to collect the printed paper. Starting the motor seat 13 can drive the screw 14 to rotate, thereby driving the adjustment area 2 to move left and right, and adjusting the left and right position of the inkjet device. The slide bar 15 can improve the stability of the adjustment area 2 when it moves. The electric lifting seat 26 can drive the inkjet plate 27 to move up and down, thereby driving the inkjet device 3 on the surface of the inkjet plate 27 to move up and down. When facing papers of different thicknesses, the distance between the nozzle and the printed material surface can be adjusted and maintained. An ink tank 31 for storing ink is installed at the top of the inner part of the inkjet device 3. Ink can be transported through multiple ink supply tubes 33 at the lower end of the ink tank 31. Piezoelectric output and input can be performed to the inside of the piezoelectric ceramic sleeve 35 through the input end 36 and the output end 37. When the piezoelectric ceramic sleeve 35 is subjected to piezoelectricity, it will deform inward and squeeze the ink supply tube 33, thereby squeezing out the ink, and finally spraying it out through the inkjet head 34.

[0039] In use, when paper is transported, the first push rod 41 can be used to push the printing paper 43 to the surface of the second sensor head 45 and the first sensor head 44. By setting the first sensor head 44 and the second sensor head 45, it is possible to prevent the corners of the paper from being skewed during pushing and triggering the detection distance to return to zero in advance. When the first sensor head 44 and the second sensor head 45 simultaneously detect that the distance of the printing paper 43 is zero, the pushing of the first push rod 41 is stopped, and the laser distance measuring head 42 is used to detect the distance between the printing paper 43 and the laser distance measuring head 42 at this time, thereby detecting the width of the printing paper 43. Then, the left electric push rod 46 and the right electric push rod 47 are used to simultaneously push the printing paper 43 to the central part, so that the printing position of the paper is located at the central position below the inkjet device to avoid deviation in the printing position. At this time, the inkjet device 3 is started to print the central printing area 431 at the center of the paper. When printing the next print paper 43, the collected paper width is sent to the control console 12 and the inkjet control console 23, and the frame 11 is used to control the adjustment area 2 to offset. The offset distance can be set in a certain proportion according to the printing time of a single sheet of paper and the width of the paper. At the same time, the inkjet control console 23 is used to control the nozzle at the inkjet device 3 to switch to the opposite direction of the adjustment area 2 by an equal amount.

[0040] The working nozzles are changed while the image position remains unchanged, so that the nozzles of all nozzles can be kept in a regular working state in a round-robin manner, thus achieving a continuous working mode without the need for scattered spraying maintenance. This greatly improves work efficiency and significantly reduces ink loss.
