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 4, a slitting cutter auto-change over device, including bottom plate 1, two slide rails 2 have been erect to the symmetry on bottom plate 1, be equipped with sliding bracket 3 in the slide rail 2, install two sets of different slitting cutters 4 on the sliding bracket 3, still be equipped with two hydraulic stems one 5 between sliding bracket 3 and bottom plate 1, thereby hydraulic stem one 5 controls the slitting cutter 4 that the height of sliding bracket 3 used through flexible control, still be provided with on bottom plate 1 and drive slitting cutter 4 work at the actuating mechanism 6 that can switch over the relation of connection between different slitting cutters 4.

In this embodiment, the sliding rail 2 also has a limiting function on the sliding mounting frame 3, so that the sliding mounting frame can only move up and down without moving or rotating in any other direction.

In this embodiment, the slitting tool 4 is provided with an upper tool shaft 401 and a lower tool shaft 402, and power is transmitted between the upper tool shaft 401 and the lower tool shaft 402 through a pair of meshed gears 403.
