DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a safety protection mechanism for a paper cutting system, comprising a bottom plate 1, a bracket 2 fixed on the bottom plate 1, a cylinder 3 fixedly installed on the top of the bracket 2, a guide bar 4 fixedly connected to the output end of the cylinder 3, a blade 14 for cutting paper fixedly connected to the bottom of the guide bar 4, a connecting bar 5 fixedly connected to the front side wall of the guide bar 4, and a protective frame 8 connected to the connecting bar 5 through an elastic telescopic member.

[0024] A protective frame 8 is provided on the front side of the guide bar 4. When the protective frame 8 contacts the paper, the protective frame 8 can play a pressing role under the action of the elastic telescopic member, and at the same time play a protective role during cutting; and in the process of paper feeding, the protective frame 8 on the front side prevents the hand from contacting the blade 14, thereby achieving the protection purpose; and a connecting strip 5, an elastic telescopic member and a protective frame 8 (not shown in the figure) can also be provided on the rear side of the guide bar 4, and the connection method is the same as that of the front side. When the cut paper is unloaded, the protection of the hand can also be achieved, and the effect is better.
