DETAILED DESCRIPTION

[0020] In order to make the purpose and advantages of the utility more clear and explicit, the utility is specifically described below in combination with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the utility, and does not strictly limit the protection scope of the utility.

[0021] For example, Figures 1-4As shown in, a paper roll cutting device, including the bottom plate 1, the top surface of the bottom plate 1 is fixedly connected with two support rods 2, the top end of the two support rods 2 is fixedly connected with the same cross beam 3, the side wall of the cross beam 3 is slidably connected with several adjusting blocks 4, the side wall of the adjusting block 4 is assembled with the movable block 5, the first bolt 6 is assembled between the movable block 5 and the adjusting block 4, the end surface of the movable block 5 is fixedly connected with two arc plates 7, the side wall of the arc plate 7 is provided with a through slot 8, the mounting block 9 is arranged between the two arc plates 7, the side wall of the mounting block 9 is provided with a locking piece, the side wall of the mounting block 9 is provided with a mounting slot 10, and the cutting knife 11 is arranged in the mounting slot 10.

[0022] As shown in Figure 3 The side wall of the mounting block 9 is threadedly connected with two screws 12, and the screws 12 penetrate the mounting slot 10. The mounting slot 10 does not penetrate the front side wall of the mounting block 9. When the cutting knife 11 is clamped into the mounting slot 10, the screws 12 are tightened to press the mounting block 9, thereby reducing the gap between the mounting slots 10 and pressing and fixing the cutting knife 11.

[0023] As shown in Figure 4 The locking piece includes a screw sleeve 13 fixedly connected to the left and right side walls of the mounting block 9, the screw sleeve 13 is movably connected with the through slot 8, the second bolt 15 is threadedly connected in the screw sleeve 13, the gasket 14 is sleeved on the side wall of the second bolt 15, and the gasket 14 abuts against the side wall of the arc plate 7. The locking piece can conveniently fix the mounting block 9, and has the advantages of simple structure, good flexibility and not easy to loosen.
