[0045] The working process of the paper cutter with a single blade structure provided in this embodiment is as follows: Compared with the paper cutter using double blades for cutting, the embodiment of the utility model provides the advantages of low cost and long service life.

[0046] First, load the power supply battery 17 into the power supply battery 17, and then turn on the power switch of the paper cutter.

[0047] The user starts the paper cutter to cut paper by touch sensing or infrared sensing.

[0048] When the paper cutter receives a signal from the user that paper is needed, the paper feed drive assembly 2 drives the upper paper feed roller 3 to rotate, so that the upper paper feed roller 3 and the lower paper feed roller 4 clamp the paper and transport it between the paper pressing rack 9 and the paper support 12.

[0049] When the paper is transported to a specified length, the paper feed drive assembly 2 stops.

[0050] The paper pressing frame 9 and the paper support 12 are fixed, and the lifting drive assembly 8 drives the paper pressing frame 9 to descend, and the paper pressing frame 9 and the paper support 12 fix the upper and lower surfaces of the paper.

[0051] After fixing, the paper pressing frame 9 is continuously driven to descend, the lifting compression spring 11 is gradually compressed, the paper support frame 12 is lower than the height of the paper cutter 7, and the piercing teeth pierce the paper.

[0052] After the piercing and cutting is completed, the lifting drive assembly 8 controls the paper pressing frame 9 to reset, and the lifting compression spring 11 also pushes the paper support frame 12 to gradually reset.

[0053] Due to the setting of the paper cutting notch 701, a small part of the paper cutting assembly is connected, and the user can take out the paper by lightly pulling the paper outlet 1011, thus completing the entire paper cutting process.

[0054] The adoption of the mechanism can effectively solve the problems of high use cost, high matching precision and short service life of the paper cutter in the prior art which adopts the double-knife paper cutting method. By using the product structure, the paper pressing component cooperates with the paper support component to fix the paper, and then the paper is pierced by the paper cutter 7, and the paper is cut by combining dynamic and static methods. The paper cutter 7 only contacts with the paper, which effectively increases the service life of the paper cutter 7, reduces the production cost, improves the user experience, and is conducive to improving the competitiveness of the enterprise.

[0055] The specific implementation methods described above are preferred implementation methods of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
