Edge pressing sample trimmer

Abstract

The invention discloses an edge pressing sample trimmer. A receding groove is formed in the upper surface of a base of the trimmer, a trimming width positioning block is installed inside the receding groove, two fixing seats are arranged on the upper surface of the base, two guide pillars and a sliding block are arranged between the two fixing seats, a blade fixing bock is arranged under the sliding block and provided with trimming blades, and the trimming blades are fixed though a blade clamping block. When the edge pressing sample trimmer works, the sliding block is pushed so that the blade fixing block and the two trimming blades can move forwards, and the two trimming blades finish the trimming operation on corrugated paper through trimming blade edges. The trimming blade edges are respectively of a single-edge structure, and the edge surfaces are outward, and the trimming blade edges of the single-edge structure can guarantee the perpendicularity between a trimming surface of the corrugated paper and the surface of a sample. The invention further discloses a trimming method which comprises the steps of putting the corrugated paper, positioning the corrugated paper, trimming the corrugated paper, driving a handle to reset, taking down the sample and the like, and the above steps can guarantee the perpendicularity between the trimming surface of the corrugated paper and the surface of the sample and the consistency of the width of the sample.

Description

technical field [0001] The invention relates to the technical field of laboratory sample cutting devices, in particular to a side pressure sample cutter. Background technique [0002] As an important paper type, corrugated paper is widely used in packaging boxes; among them, when testing corrugated cardboard products, edge pressure tests must be carried out in accordance with international standards or national standards to test the performance of the side of the cardboard under pressure, and corrugated paper Only when the requirements are met can it be used in the packaging box, especially in some special packaging boxes. [0003] Before carrying out the edge pressure test, the existing technology generally uses a middle-edged blade to cut corrugated paper, but the cutting surface of the corrugated paper sample cut by the middle-edged blade cannot guarantee the perpendicularity to the surface of the corrugated paper, which brings a problem to the test results. A large erro...

Problems solved by technology

[0003] Before carrying out the edge pressure test, the existing technology generally uses a middle-edged blade to cut corrugated paper, but the cutting surface of the corrugated paper sample cut by the middle-edged blade cannot guarantee the perpendicularity to the surface of the corrugated paper, which brings a problem to the test results. A large error (usually the size error exceeds 1mm), or because of the perpendicularity factor between the cutting surface and the sample surface, brings a large measurement uncertainty to the results of the edge pressure test of corrugated cardboard
