[0004] The size of the transverse cutter in the above scheme is fixed. Since a sheet of paper may need to be slotted with slots of multiple sizes, a transverse cutter of a single size cannot be slotted, which limits its practicality. Therefore, a transverse slotting device for a printing press is proposed. Utility Model Content

[0005] The utility model aims to solve the problems raised by the background technology and proposes a transverse slotting device for a printing press.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0016] Compared with the prior art, the utility model provides a transverse slotting device for a printing press, which has the following beneficial effects:

[0017] 1. The transverse slotting device of the printing press is provided with a transverse cutter and a pressing rod on the protective cover. Since the sizes of the multiple transverse cutters are different, when slots of different sizes need to be opened, it is only necessary to push the pressing rod of the corresponding transverse cutter by hand to push the transverse cutter out from the bottom of the protective cover. At this time, the protective cover is driven downward by the cylinder, so that the transverse cutter can operate to slot on the cardboard.

[0018] 2. The transverse grooving device of the printing press is provided with a telescopic tube and a first spring. When it is necessary to store the transverse cutter exposed outside the protective cover, the first spring applies elastic force to the transverse cutter, so that the telescopic tube retracts and stores the transverse cutter inside the protective cover.

[0019] 3. The transverse slotting device of the printing machine is provided with a push rod, a clamping rod and a second spring on the pressing rod. After the pressing rod pushes out or stores the transverse cutter, the second spring applies elastic force to the two push rods, so that the two push rods drive the clamping rods to extend and be clamped with the inner wall of the protective cover, so that the transverse cutter can be stably stored inside the protective cover.

[0020] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model has transverse cutters of various sizes. When grooves of different sizes need to be opened, it is only necessary to push out the transverse cutters of the corresponding sizes, thereby improving the efficiency and practicality of the groove opening.
