A wet slurry sample placement device and its control method

Abstract

The present invention relates to the technical field of paper pulp whiteness detection during a pulping papermaking process, more particularly to a wet pulp sample placement apparatus and a control method thereof. The wet pulp sample placement apparatus comprises a first motor, a sliding track connected with the first motor, and a sliding block arranged on the sliding track, wherein the upper end portion and the lower end portion of the sliding track are respectively provided with an upper position limitation switch and a lower position limitation switch. The wet pulp sample placement apparatus further comprises a second motor, a rotation shaft and a tray, wherein the second motor is fixed on the sliding block, one end of the rotation shaft is connected with the second motor, the other end is connected with the tray, and the second motor is provided for driving the tray to rotate through the rotation shaft. The wet pulp sample placement apparatus further comprises a single-chip computer arranged inside the wet pulp sample placement apparatus, wherein the single-chip computer is respectively and electrically connected with the first motor, the second motor, the upper position limitation switch and the lower position limitation switch. The wet pulp sample placement apparatus has the following characteristics that: the structure is simple, up and down displacement can be achieved, 360 DEG rotation can be achieved, and the apparatus can be adopted to replace manual rotation of a sample requiring detection, such that the whiteness detection result of the sample is accurate.

Description

technical field [0001] The invention relates to the technical field of equipment for pulp whiteness detection in the process of pulping and papermaking, and more particularly, relates to a wet pulp sample placement device and a control method thereof. Background technique [0002] All whiteness meters currently on the market, including those used to test paper whiteness, do not have a dedicated wet sample placement device. Manually turning the paper or paddle in this way will pollute the sample to be tested, thereby affecting the accuracy of the measurement result. Especially when testing wet slurry samples, the samples are easily deformed and polluted due to their high water content, and the surface smoothness of the samples has a great influence on the whiteness detection, which in turn causes great errors in the measurement results. Contents of the invention [0003] In order to overcome at least one defect described in the above-mentioned prior art, the present invent...
