Description

Cutting machine{CUTTING MACHINE}

The present invention relates to a cutting device, and more particularly, to a cutting device for cutting the printed paper to fit the dimensions.

In general, when cutting printed paper or flyers, the cutter includes a transport assembly installed on a rail to perform a translational movement across the cutting plate, and is used for cutting or cutting various papers.

In the conventional Korean Patent Publication No. 0327190, the paper cutter 10 is composed of a cutting plate 20, a rail assembly 30, and a transport assembly 40. The cutting plate 20 is provided on a measuring display strip 24 measured by two different measuring instruments, and the two measuring instruments are a first measuring instrument 24' measured in imperial units such as inches and a meter/SI such as centimeter. It includes a second measurer (24'') measured in units.

The rail assembly 30 is rotatably attached to the cutting plate 20 by a pivot shaft 37', 37'' to each side end portion 35', 35'' of the cutting plate 20, It is formed to extend perpendicular to the measurement display strip 24. The transport assembly 40 is slidably installed on the rail 32 of the rail assembly 30, and includes a blade 44 for cutting a similar seed material such as cutting paper or gasket material and plastic sign stock. The blade 44 is circular in shape and operates in a rotary manner, and has a simple edge sharpened along the circumference for continuous straight cutting operation. Optionally, the blade 44 has blades formed suitable for collinear work, scalloped cutting or saw-blade cutting, or other modified cutting operations.

In the case of the conventional paper cutter 10 having the above-described configuration, the user lifts the transport assembly 40 from the cutting plate 20 in a swinging motion, and places paper sheets on the cutting plate 20. After that, it is lowered to the transport assembly 40 to fix the paper sheet. Subsequently, the user slides the transport assembly 40 along the rail 32, and accordingly, the circular blade of the blade 44 touches the paper sheet and the paper sheet is cut. At this time, a self-healing pad is installed on the cutting plate 20 where the circular blade of the blade 44 abuts along the movement path of the blade 44 to provide a smooth cutting surface.

However, since such a conventional paper cutter 10 continuously uses the blade 44 to cut a sheet of paper, the self-healing pad is damaged, and the self-healing pad and the paper cutter dedicated blade are used after a certain period of time. There is a hassle of having to replace it.

It is bent at a predetermined angle from the tip of the wing surface to extend, and when the wing surface is deformed, a tail surface surrounding the circular elastic member; Including,
The circular elastic member,
A cutting device that is fastened to the attachment surface through a fastening means and provided between the attachment surface and the wing surface, and restores the original state when the wing surface is deformed due to its own elastic force.
