Embodiment Construction

[0020] Description with reference to the accompanying drawings.

[0021] The paper cutting device frame body of the illustrated embodiment includes left and right vertical wallboards 11 and a bottom surface. The wallboards 11 on both sides are parallel to each other. The upper part between them is equipped with an upper knife linear guide rail 8, and the upper knife linear guide rail 8 is perpendicular to the wall panel 11. , the rubber wheel seat linear guide 7 on the bottom surface is parallel to the upper knife linear guide 8, see figure 2 .

[0022] figure 2 and 4 As shown, the upper knife rotates and drives the power to drive the upper knife 1 to rotate. The rotary drive power of the upper knife in this embodiment is the rotary drive motor 9 for the upper knife, and the output power of the rotary drive motor 9 installed on the left wallboard 11 is transmitted to the active synchronous belt for the rotary drive of the upper knife through the synchronous pulley and the...

Abstract

The invention relates to a paper cutter, and in particular relates to a paper cutting device of a paper cutter without a lower cutter. The paper cutting device is used for cutting paper. The paper cutting device is characterized in that an upper cutter is matched with the external diameter of a rubber wheel installed on a rubber wheel seat to cut paper; the upper cutter is vertical to the axis of the rubber wheel; and a paper supporting plate is fixedly installed on the rubber wheel seat. The paper cutting device has the following advantages that the technical problems that the paper cutting devices of the existing paper cutters are easily worn, are short in service life and high in costs, waste time and labour in changing cutters and generate deckle edges and winding when in cutting paper are solved.

Description

technical field [0001] The invention relates to a paper cutter, in particular to a paper cutting device of a paper cutter without a lower knife. Background technique [0002] The paper cutting device of the traditional paper cutter uses metal upper and lower blades to cut the paper. The long-term mutual friction and collision during the knife setting greatly reduce the service life of the upper knife, and the phenomenon of knife collapse occurs from time to time. , and it takes time and effort to change the knife, and the paper is prone to burrs. Chinese Invention Patent Publication No. CN 1954978A "Paper Cutting Device" discloses a paper cutting device in which a wheel-shaped knife seat is made of rubber material, and the lower circular knife suit is fixed on the knife seat. Although this patent reduces the difficulty and time of changing the knife, it does not fundamentally solve the defects that the blade is easy to wear and paper cutting is prone to burrs. Chinese Util...
