Description

Technical Field

[0001] The utility model relates to the technical field of paper cutters, in particular to a paper cutter. Background Art

[0002] In the prior art, the cutting devices mainly include: a circular quantitative sampler that can cut paper samples of 100 cm2 in size, a punching tool that can cut 15 mm × 250 mm or 25 mm × 250 mm, and a paper cutter that can cut 15 mm × 300 mm or 300 mm × 360 mm. However, they are all cutting tools for a specific standard, and the paper samples they need to cut are all flat products. It is relatively difficult to cut pulp molded products (paper cups, paper bowls, etc.) with three-dimensional shapes. However, in the current paper product hygiene standards, there are cutting requirements in the sample preparation processes of formaldehyde, lead, and arsenic for the detection items of paper cups and paper bowls. Among them, the formaldehyde sample preparation requires making small pieces of 1 cm2, and the sample preparation of arsenic and lead requires pulverizing and mixing evenly before weighing, and the amount of each sample cutting is relatively large. If cut by hand with scissors according to the standard requirements, it will significantly increase the workload in the early stage of the inspection process, which is not conducive to the development of a large amount of work. At the same time, when facing multi-layer cardboard, it is easy to produce offset between the cardboard layers, affecting the work.

[0003] Therefore, this application proposes a paper cutter to solve the above problems. Content of the Utility Model
