As shown in fig. 1 and 2, taking the example of printing a straight line to the left, fig. 2 is the printed straight line, and the straight line is divided into a first line segment 500, a second line segment 600, a third line segment 700 and a fourth line segment 800, wherein the first line segment 500 is printed by the first nozzle 100, the second line segment 600 is printed by the second nozzle 200, the third line segment 700 is printed by the third nozzle 300, and the fourth line segment 800 is printed by the fourth nozzle 400. When moving to the left, the first nozzle 100 and the third nozzle 300 move to the preset positions to print the first line segment 500 and the third line segment 700, and when the second nozzle 200 and the fourth nozzle 400 move to the preset positions, the nozzles are controlled to print the second line segment 600 and the fourth line segment 800. As shown in fig. 3, if the second head 200 and the fourth head 400 are tilted, the tilted line segments shown in fig. 4 are printed. During debugging, the lines printed by the first nozzle 100 are used as a reference, and the lines printed by the nozzle and the reference lines are collinear and part of ink jet points are overlapped by sequentially and manually finely adjusting the positions of the second nozzle 200, the third nozzle 300 and the fourth nozzle 400 and the ink jet time.

In this installation method, each nozzle of the existing scanning digital printing equipment needs to perform independent position adjustment and ink jet time adjustment, the adjustment workload of the nozzle is doubled with the increase of the number of the nozzles, and the randomness and the single adjustment displacement are large when the position of the nozzle is adjusted, so that the nozzle is difficult to align to the reference.

When the linear adjustment expansion device 113 is extended by using the adjustment mechanism 11, the linear adjustment expansion device 113 pushes one end of the movable element 112 to operate the movable element 112, and at the same time, the spring 115 pulls the movable element 112 to move the movable element 112 toward the fixed element 111, and the angle adjustment expansion device 114 abuts against the other end of the movable element 112 to block the movable element 112 from moving toward the fixed element 111, so that the movable element 112 can only move linearly in the direction in which the linear adjustment expansion device 113 is extended; when the linear adjustment expansion element 113 is shortened, one end of the movable element 112 loses the support of the linear adjustment expansion element 113, and the movable element 112 moves linearly in the direction of shortening the linear adjustment expansion element 113 under the pulling action of the spring 115 and the blocking force of the angle adjustment expansion element 114; in this way, the position of the regulating small plate 12 in the front-rear direction can be regulated. When the angle adjustment telescopic element 114 is extended, the angle adjustment telescopic element 114 pushes the other end of the movable element 112 to move away from the fixed element 111, and at the same time, the spring 115 pulls the movable element 112 to make the movable element 112 abut against the angle adjustment telescopic element 114 and the linear adjustment telescopic element 113, and the linear adjustment telescopic element 113 provides a supporting force for one end of the movable element 112, so that the movable element 112 rotates counterclockwise with one end of the linear adjustment telescopic element as a rotating shaft; when the angle adjustment telescopic element 114 is shortened, the other end of the movable element 112 loses the support of the angle adjustment telescopic element 114, and under the pulling action of the spring 115 and the support of the linear adjustment telescopic element 113, the movable element 112 can rotate clockwise with one end of the movable element as a rotating shaft; in this way, the angle of the small adjusting plate 12 can be adjusted, so that the lines printed by the first nozzle 13 are changed from being inclined to being collinear.
