Temperature-adjustable paper flexibility testing device

Abstract

The invention relates to a device in the technical field of paper testing, which is a temperature-adjustable paper flexibility testing device. The temperature-adjustable paper flexibility testing device comprises a device body; the device body comprises a working panel; two parallel vertical plates are installed on the working panel; the various vertical plates are provided with transverse slidinggrooves, namely the front sliding groove and the rear sliding groove; furthermore, sliding blocks are installed in the sliding grooves; the two sliding blocks are the front sliding block and the rearsliding block respectively; the device further comprises a cover body; the cover body is a structure covering the parts; the four sides at the lower side of the cover body are installed at four sidesof the working panel; the cover body is provided with a cover thereon; the device further comprises a semiconductor refrigeration part installed on the side surface of the cover body; and the semiconductor refrigeration part is provided with a power connection line. The paper flexibility testing device in the invention has the advantage of being relatively accurate in test numerical value, and also has the advantage of being capable of testing the paper flexibility at different temperatures.

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 clamps that clamp both ends ...

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 flexural properties of paper are different at different temperatures. The existing technology only tests the flexural properties of paper at room temperature, and cannot test the flexural properties of paper at different temperatures, which has the disadvantage of being inconvenient to use.
