Inverted paper cutting machine with upward cutting edge

Abstract

The invention relates to an inverted paper cutting machine with an upward cutting edge. The inverted paper cutting machine comprises a cutter driving mechanism and a spring paper pressing mechanism, wherein the cutter driving mechanism comprises a connecting rod and a cutter rest, the cutter rest is fixedly connected with a first sliding block, the spring paper pressing mechanism comprises a motorbase, a shell of a motor is fixedly connected with a paper pressing frame, an output shaft of the motor is connected with a power input shaft, and a supporting plate is connected with the paper pressing frame. According to the inverted paper cutting machine, the paper pressing frame is enabled to press paper downwards through the gravity of the motor and the action of a second spring, a cam drives the connecting rod to generate internal supporting force so as to drive the cutter rest to move upwards, a cutter is driven to move upwards to cut the paper, generated paper scraps fall into a paperscrap box in a machine frame through a first inclined surface of the cutter under the action of the gravity of the paper scraps, moreover, and scraps do not need to be cleaned after cutting, so thatthe cutting efficiency is improved; the cutter rest moves downwards during cutter retracting, the second spring pulls back a working table plate to enable the working table plate to be automatically closed, so that the cutter is covered, and the safety is improved; and the image space of cutting is subverted, and various elements of cutting can be endowed.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a paper cutting device, in particular to an inverted paper cutting machine with upward blades. Background technique [0002] The paper cutter is widely used to trim the paper in the binding process to meet the paper cutting needs in the later stage of printing. In the prior art, the working process of the power paper cutter includes a paper pressing action and a paper cutting action. In the paper pressing action, the paper is placed under the knife, and in the paper cutting action, the knife moves downward to cut the paper. During the cutting process, the debris generated by the upper layer of paper falls with the cutter to the uncut lower layer of paper and the frame under the action of gravity. low efficiency. Contents of the invention [0003] The present invention provides an upside-down paper cutter with an upward blade. The paper cutter with an upside-down blade should solve th...

Problems solved by technology

[0003] The present invention provides an upside-down paper cutter with an upward blade. The paper cutter with an upside-down blade should solve the problem of debris generated by the upper layer of paper when the cutter moves downward to cut the paper in the prior art. Under the action of gravity, the tool falls to the lower layer of paper that has not been cut, which may easily lead to technical problems such as uneven cutting and long-term accumulation of debris inside the machine
