The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-4, the present invention provides an embodiment: a novel paper cutting machine comprises a bottom plate 1; a first upright post 2 is arranged on one side of the bottom plate 1; a second upright post 9 is arranged on the other side of the bottom plate 1; the number of the first upright posts 2 and the second upright posts 9 is two, which are symmetrically arranged on the width surface of the bottom plate 1, namely: the transverse rod 5 horizontally slides in the front-back direction, and the length surface of the bottom plate 1 is the left-right sliding direction of the paper cutter 6; a screw rod 3 is in threaded fit with the first upright post 2; the second upright post 9 is provided with a guide rod 7; a cross rod 5 is in threaded fit with the screw rod 3, and the other end of the cross rod 5 is in sliding fit with the guide rod 7; the first upright post 2 is also provided with a graduated scale 4 for indicating the moving position of the cross rod 5; the cross rod 5 is matched with a paper cutter 6 in a sliding mode, and the scale value of the upper surface of the cross rod 5 is 8.

The paper on the base plate 1 is cut and separated by sliding the paper cutter 6 on the cross bar 5;

the scale 4 can accurately control the front and back movement distance of the cross rod 5, meanwhile, the cross rod 5 is also provided with a scale value 8, and the left and right movement distance of the paper cutter 6 can be accurately controlled, wherein the unit of the scale on the scale 4 and the unit of the scale on the cross rod 5 are both millimeters, and the requirement of paper cutting precision is basically met;

by the scheme, the device not only realizes accurate cutting of paper size, but also is convenient to use and low in use cost; particularly, the device solves the problems that office fragmentary paper cannot be accurately cut in time and large-scale cutting equipment is not used;

meanwhile, the paper cutting can be finished without moving the paper by sliding the paper cutter 6 and driving the transverse rod 5 to move by using the screw 3, so that the paper can be cut more orderly, and particularly, the initial position of the paper is always kept unchanged no matter how many times the paper is cut.

In order to facilitate the sliding of the paper cutter 6 and the installation of the paper cutter 6 on the cross bar 5, the paper cutter 6 comprises a cylindrical connecting part 61, and a sliding hole 68 matched with the cross bar 5 is formed in the middle of the connecting part 61;

because the connecting rod 67 is arranged below the connecting part 61, the connecting rod 67 is connected with the tool rest 65; the connecting rod 67 and the tool rest 65 which are arranged separately enable the tool rest 65 to be convenient to mount and dismount, and particularly facilitate the change of the angle of the tool rest 65;

the knife rest 65 is provided with a blade 63 and a pinch roller 64 for pressing paper; the blade 63 is positioned on the side surface of the knife rest 65, the pinch roller 64 is positioned on the end surface of the knife rest 65, and the pinch roller 64 is used for squeezing paper, so that the problem of creasing of the paper is avoided; it should be noted that the radial surface of the pressing wheel 64 is parallel to the blade 63, and the parallel arrangement makes the circumferential surface of the pressing wheel 64 always tangent to the upper surface of the paper when moving along with the tool rest 65, so as to further ensure the compaction of the paper; in addition, the cutting edge of the blade 63 is obliquely arranged, the included angle between the blade and the bottom plate 1 is 60 degrees, and when the paper cutting knife 6 is better convenient to move, paper is pressed under the cutting edge, so that paper cutting efficiency is higher, and the cut of the paper is smoother.

In order to ensure the positioning after the angle between the connecting rod 67 and the tool rest 65 is adjusted, one surface of the connecting rod 67 facing the tool rest 65 is provided with an inward concave cross-shaped groove 610; one surface of the tool rest 65 facing the connecting rod 67 is provided with a cross column 69 matched with the cross groove 610; the cross column 69 is inserted into the cross groove 610, so that the tool holder 65 is prevented from rotating axially;

because the cross column 69 is in adaptive splicing with the cross groove 610, the cutter frame 65 is in a left and right paper cutting state under the conventional state; when paper needs to be cut forwards and backwards, the cutter frame 65 is pulled down and rotates 90 degrees anticlockwise, and then the cross column 69 is inserted into the cross groove 610, so that the paper can be cut forwards and backwards; through the scheme, the knife rest 65 is convenient to rotate in angle and convenient to position after rotating.

In order to further realize the fixed connection of the connecting rod 67 and the tool rest 65; the connecting rod 67 is also sleeved with a sleeve 62, and the connecting rod 67 is fixedly connected with the tool rest 65 through a bolt 66 arranged on the sleeve 62; meanwhile, the blade 63 is fixed on the tool rest 65 by using the bolt 66, so that the blade 63 is convenient to disassemble and assemble.

Since the push plate 60 is further provided on the connecting portion 61, the left and right sliding of the paper cutter 6 can be realized by holding the push plate 60 and pushing the push plate 60 left and right.

Because the cross section of the cross bar 5 and the cross section of the sliding hole 68 are both rectangular, the sliding of the paper cutter 6 is facilitated on one hand, and the axial rotation of the paper cutter 6 is avoided on the other hand; thus, the sliding of the cutter 6 can be smoothly performed, thereby improving the flatness of the paper cut.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
