The code spraying machine is a device which is controlled by software and performs identification on products in a non-contact mode. The main process is divided into two steps; in the first step, paper is penetrated between the spray gun and the blanket cylinder, and the paper is transported through the rotation of the blanket cylinder. And secondly, spraying codes by matching with a spray gun. In the first step, the gripper has to be referred to as a spare part, which is functionally divided into a transfer gripper for gripping the sheet on the sheet transport plate and a gripper for transferring the sheet in the printing cylinder. To ensure stability of sheet delivery, the grippers are typically plural, uniformly arranged at the nip of the impression cylinder.
In actual production, deformation of the gripper is often caused by insufficient gripper cleaning, reduced gripper force, abnormal gripper bar delivery and the like. The most common of these is the turning up and tilting of the grippers. Because the distance between the spray gun and the impression cylinder is very close, the tilted gripper is easy to collide with or scratch the accurate spray gun head, and the loss is very large. Moreover, the number of grippers is large, and the grippers are frequently used, so that the time and effort are very consumed for checking one by one, the maintenance is difficult, and the method is not a judicious choice. Thus, there is a need for a solution.

The utility model provides two anti-collision processes by arranging the elastic piece 40, and the code spraying body is protected by the sequential change of the tilting state of the grippers 21. Firstly, the code spraying body is separated from the gripper 21 by the blocking surface 41a, so that the gripper 21 is preferentially hit on the blocking surface when being lifted up; secondly, the elastic restoring action of the elastic unit 42 is matched, so that the blocking surface is always in abutting and pressing fit with the gripper 21, the raising speed of the gripper 21 is slowed down, and the problem that the abrupt abnormal protrusions scratch the code spraying body 10 is avoided. The two are mutually complemented, so that the damage of the code spraying body 10 is radically avoided.
