The paper continues to rotate with the drum and passes through the paper feed switch 400 again, at which time the paper feed switch 400 remains closed. The cylinder continues to rotate and reaches the inkjet printing mechanism 700 again, and the inkjet printing mechanism 700 prints on the second surface of the paper, so that double-sided printing of the paper is achieved. When the sheet rotates around the delivery mechanism 500 again along with the drum, the delivery switch device 600 is turned on, the delivery mechanism gripper bar 530 grips the tail side of the sheet, the gripper 220 on the drum is released, and the delivery mechanism chain 510 transfers the sheet to the delivery table 540, completing the whole double-sided printing process.
In the process, a sheet is received by each group of gripper devices on the cylinder mechanism 200 at intervals, that is, every 240 degrees of cylinder rotation. Accordingly, after the first side of the first sheet on the drum is printed, the sheet turnover mechanism 800 turns over the first sheet, and then, every 240 degrees of rotation of the drum, the sheet turnover mechanism 800 turns over the sheet at that position. After printing on the second side of the first sheet on the platen is completed, the delivery mechanism 500 transfers the first sheet from the platen to the delivery station 540, and then, every 240 degrees the platen rotates, the delivery mechanism 500 picks up and transfers the sheet at that position.
Fig. 6 is a flowchart of an inkjet printer according to an embodiment of the present application during single-sided printing.
Referring to fig. 6, the present embodiment can also be used for single-sided printing of paper. Specifically, when the single-sided printing of the sheet is performed, the sheet storage table 310 starts to be transported, passes through the sheet feeding mechanism 300, reaches the platen surface of the platen mechanism 200, and during this time, the sheet feeding switching device 400 is kept on. The leading side of the sheet reaches the position of the stop 210 in one of the sets of grippers on the cylinder mechanism 200, and the gripper 220 grips the leading side of the sheet as the cylinder rotates, thereby gradually moving the sheet to the surface of the cylinder. The platen rotates to the inkjet printing mechanism 700 and the inkjet printing mechanism 700 prints on a first side of the sheet. Subsequently, the drum continues to rotate past the delivery mechanism 500, the delivery switch 600 is opened, the delivery mechanism gripper bar 530 grips the paper at the paper head side, the gripper 220 on the drum is released, and the delivery mechanism chain 510 transfers the paper to the delivery station 540, completing the whole paper single-sided printing process.
In the process, each group of gripper devices on the cylinder mechanism 200 receives a sheet, that is, each 120 degree rotation of the cylinder, to hold a new sheet. Accordingly, after printing the first sheet on the platen is completed, the delivery mechanism 500 transfers the first sheet from the platen to the delivery station 540, and then, every 120 degrees the platen is rotated, the delivery mechanism 500 picks up and transfers the sheet at that position.
