Crumpling amplitude-adjustable paper crumpling performance test device

Abstract

The invention relates to equipment in the technical field of paper test, and relates to a crumpling amplitude-adjustable paper crumpling performance test device. The crumpling amplitude-adjustable paper crumpling performance test device comprises a device body, wherein the device body further comprises a working panel, two parallel vertical plates are arranged on the working panel, a horizontal sliding groove is formed in each vertical plate, a sliding block is arranged in each sliding groove, each sliding block is provided with a clamp in the corresponding vertical plate, a side surface of around frame is connected to a rack, a roller is arranged in the round frame, a lower surface of the roller is in contact with a transmission wheel, a roller side is connected with the front sliding block via a front connection rod, a plurality of front connection points and a plurality of rear connection points are arranged on the transmission wheel and are distributed on the diameter of the transmission wheel, the front connection rod is detachably arranged on the front connection points, a rear connection rod is detachably arranged on the rear connection points, thus, the crumpling amplitude-adjustable paper crumpling performance test device has the advantage of more accurate test numerical value and also has the advantage of adjusting the crumpling amplitude of the paper.

Description

technical field [0001] The invention relates to equipment in the technical field of paper testing, in particular to a device for testing paper flexural properties. Background technique [0002] The flexible folding performance of the paper refers to the changes in the strength of the paper after being folded many times. It is an important index to measure the performance of the paper. The flexible folding performance of the paper means that it has better folding resistance, especially Especially on the tipping paper and cigarette paper of cigarettes, this index is more important. Manufacturers and users hope that the paper used has good flexural properties. [0003] The method of measuring the flexural performance of paper is as follows: First, cut a paper strip with a length of 25-30 cm and a width of 10 cm as a test paper, and place a piece of test paper on the paper tensile strength tester. Of course, the paper tensile strength The tester has clips that clamp both ends o...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there is no special test device for testing the flexural performance of paper. It relies on people's manual rubbing. However, manual hand rubbing has the disadvantages that the strength and magnitude of rubbing are not easy to control, which affects the test. The results cannot meet the requirements of more accurate figures

[0005] In addition, the rubbing range of the paper cannot be adjusted, that is, the rubbing stroke cannot be adjusted, which has the disadvantage of inconvenient use.
