The designated state in the actual production process can be various, and can be self-defined according to the actual situation, as shown in fig. 8, the designated state in this application means that the long convex edge 111 at the rear end of the printing cylinder is located in the advancing direction of the placing position 133 of the feeding turntable 103, and the liquid outlet port 114 of the cylinder 105 to be printed is located inside the placing position 133.

The specific scheme is as follows:

referring to fig. 6 to 9, a guide slope 110 is formed at the front end of the positioning rail 108, and the long flange 111 at the rear end of the printing cylinder 105 rotates while moving on the guide slope 110 to be adjusted to the first state, and in order to ensure the accurate adjustment of the first state, a transfer groove 112 is formed on the positioning rail 108 behind the vertex of the guide slope 110, and the transfer groove 112 is lower than the vertex of the guide slope 110, and the vertex of the guide slope 110 is lower than the upper end surface of the positioning rail 108.

As shown in fig. 7, the cylinder 105 to be printed after passing through the guide slope 110 enters the transfer slot 112, and the first state is formed after adjustment of the transfer slot 112.

The above-described transfer slot 112 is not necessarily designed, and the cylinder 105 to be printed may be adjusted to the first state by the guide slope 110 without the transfer slot 112.

The function of the transfer slot 112 is to make the process of adjusting the cylinder 105 to be printed to the first state smoother, reduce wear, and avoid the occurrence of burrs on the edge of the cylinder 105 to be printed.

The lowest point of the wire inclined plane 110 is located on the plane where the upper end surface of the feeding turntable 103 is located, and the distance from the wire inclined plane 110 to the center point of the placing position is less than half of the connecting line L of the long convex edge 111, so that the effect that only the long convex edge can move on the wire inclined plane 110 is achieved.

When the cylinder 105 to be printed adjusted to the first state moves into the rotating groove 113, the sidewall of the orientation disk 109 is movably abutted against the outlet port 114 of the cylinder 105 to be printed, and the cylinder 105 to be printed is finally adjusted to a designated state.

In order to ensure that the orientation disk 109 does not excessively adjust the state of the cylinder 105 to be printed, a guide plate 134 is externally connected to the rear end of the rotating groove 113, an included angle is formed between the guide plate 134 and the rotating groove 113, and the long convex edge 111 at the rear end of the cylinder 105 to be printed is movably abutted to the guide plate 134.

The guide plate 134 restricts the rotation of the cylinder 105 to be printed, and ensures that the designated state is accurately formed.
