Description

Manual cutting mechanism

technical field

The invention discloses a manual paper cutting mechanism, which belongs to the technical field of paper cutting tools for office supplies according to the International Patent Classification (IPC).

Background technique

According to the survey of the office supplies market, when people want to cut a piece of paper, they usually use scissors or a paper cutter: after cutting with scissors, the adjacent edges of the paper are prone to non-vertical phenomena; while the current paper cutter is generally Ordinary slice knife or guillotine structure, when using ordinary slice knife, it needs to press the back of the knife to apply force, and the structure of guillotine is relatively large, so it is not suitable for cutting a certain position in the paper. However, local cutting is very important for office workers or The needs of primary and middle school students to tailor the content of learning materials are still very important.

Generally speaking, it is a difficult problem for education, learning or office personnel to cut data when processing paper documents. Based on this, the inventor created a paper cutting tool after long-term research and combined with practical applications, so the present invention is proposed.

Contents of the invention

Aiming at the deficiencies of the prior art, the invention provides a reasonable structure, safe and reliable manual paper cutting mechanism.

To achieve the above object, the present invention is achieved through the following technical solutions:

A manual paper cutting mechanism, including a serrated blade, a main body shell, a rubber ring and a top cover, wherein

Serrated blade, which is a circular blade with dense serrations along the periphery of the blade, and a transverse shaft hole in the center of the blade;

Rubber rings, which are a group and are respectively placed on the outside of the serrated blade to clamp the blade;

The main body casing is placed outside the rubber ring and the serrated blade. A fixed shaft passes through one side of the main body casing, the rubber ring, the serrated blade and the other side of the rubber ring and the other side of the main casing. The serrated blade and the rubber ring part It is exposed outside the main shell, and the top of the main shell is opened and a top cover is assembled.

Further, the top cover is a transparent cover for real-time monitoring of the cutting path.

Further, the main body casing is provided with a longitudinal groove, which is a red vertical groove and plays a guiding role, and each corner of the main body casing is set on an arc or curved surface.

Further, the two ends of the main body casing are blunt openings to form an inlet or outlet for cutting paper.

The invention adopts a circular sawtooth blade, which can well solve various problems of paper cutting, and the rubber ring holding the blade can protect the paper from being damaged when the force is heavy, and the corners of the cut paper are smooth and beautiful; at the same time, the rubber ring The ring also acts as a wheel, keeping the cutting path straight. The red bright line of the shell can play a good guiding role, and the white transparent top cover on the top gives a position reference when cutting the steering. The appearance of the present invention adopts a streamlined shape to produce a curved aesthetic feeling. The bright colors and the red line on the top play the finishing touch to the overall color matching, and its symmetrical structure conforms to the traditional Chinese aesthetic concept, supplemented by the western style of the bright color appearance to achieve the new aesthetics of Chinese and Western aesthetics. The arc-shaped structure minus the edges and corners has good hand-holding comfort. The compact shape and 5cm body length bring good operability. The top white transparent shell can refer to the position when cutting and turning, which reflects ergonomics. . In the present invention, through the finite element analysis and strength check of Autodesk Inventor software, the contact surplus test finally determines the appropriate size and material thickness.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing:

Embodiment: Please refer to Fig. 1 to Fig. 4, a kind of manual paper cutting mechanism, comprises serrated blade 1, main body shell 2, rubber ring 3 and top cover 4, wherein

Serrated blade 1, which is a circular blade, is provided with dense serrations along the periphery of the blade, and is provided with a transverse shaft hole in the center of the blade;

Rubber rings 3, which are a group and are respectively placed on the outside of the sawtooth blade to clamp the blade;

The main body shell 2, which is placed outside the rubber ring and the serrated blade, a fixed shaft passes through one side of the main body shell, the rubber ring, the serrated blade and the other side of the rubber ring and the other side of the main body shell, the serrated blade, the rubber ring A part is exposed outside the main body casing, and the top of the main body casing 2 is open and equipped with a top cover, which is a transparent cover for real-time monitoring of the cutting path.
