Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the perfecting press with turn-over device includes a first printing device 1, a turn-over device 2 and a second printing device 3 sequentially disposed.
As shown in fig. 3, the first printing unit includes a first frame 11, and a first ink roller 12, a first water roller 13, a first plate roller 14, a first squeegee 15, and a first printing roller 16 rotatably mounted in the first frame.
As shown in fig. 3, the second printing unit 3 includes a second frame 31, and a second ink roller 32, a second water roller 33, a second plate roller 34, a second squeegee 35, and a second printing roller 36 rotatably mounted in the second frame.
As shown in fig. 1 to 3, the turn-over device 2 includes a first turn roller 21, a second turn roller 22, a bracket 23, a first turn roller 24, a second turn roller 25, a third turn roller 26, a fourth turn roller 27, a third turn roller 28, and a fourth turn roller 29.
The first turning roll 21 and the second turning roll 22 are arranged on the first frame and are parallel to the first printing roll. Meanwhile, the first steering roller and the first printing roller are at the same horizontal level, and the second steering roller is positioned below the first steering roller.
As shown in fig. 1 and 2, the support 23 is composed of four upright columns distributed in a rectangular shape, and the first turnover roller, the second turnover roller, the third turnover roller and the fourth turnover roller are all fixedly connected with two upright columns in the support. Specifically, the first turnover roller and the second turning roller are positioned at the same horizontal height, and an included angle of 45 degrees is formed between the first turnover roller and the second turning roller. The second turn-over roller and the first turn-over roller are at the same horizontal height, and the second turn-over roller and the second turn roller form an included angle of 90 degrees, and meanwhile, the second turn roller, the first turn-over roller and the second turn roller which are at the same horizontal height form a roughly right-angled triangle structure. The third turnover roller and the second turnover roller are positioned on the same side, are parallel to the second turnover roller and are positioned right above the second turnover roller. And finally, the fourth turn-over roller and the third turn-over roller are positioned at the same horizontal height, and an included angle of 90 degrees is formed between the fourth turn-over roller and the first turn-over roller.
As shown in fig. 3, the third and fourth steering rollers are mounted on the second frame. The third turning roller is parallel to the second printing roller in the second printing device and is at the same horizontal height with the fourth turn-over roller. The third turn-over roller, the fourth turn-over roller and the third turning roller form a substantially right triangle.
