Abstract

The invention discloses a test-paper-strip-based automatic paper delivery device. A shell of the automatic paper delivery device is divided into two chambers; a specially-shaped rotating shaft, a test paper disc, a motor, a nylon tape guide disc, a guide wheel, a marking detection device and a separation guiding mechanism are arranged in one chamber; the test paper disc sleeves the specially-shaped rotating shaft, a test paper strip is wound on the test paper disc, the other end of the test paper strip goes around the guide wheel to be wound on the nylon tape guide disc, the nylon tape guide disc fixedly sleeves a motor rotating shaft, the marking detection device is arranged near the test paper strip, and the test paper strip is wound outside the guide wheel and is provided with the separation guiding mechanism; and a control circuit, an indicator light and a button are arranged in the other chamber; and the control circuit is connected with the button, the motor, the marking detection device and the indicator light respectively. According to the test-paper-strip-based automatic paper delivery device, the test paper can be delivered out automatically, oxidation deactivation of the test paper or cross contamination among test paper can be effectively avoided, the processes such as package tearing are removed, the automatic paper delivery device is simple, has high efficiency and can remind users of replacing the test paper disc timely.

Description

technical field [0001] The invention relates to an automatic paper output device, in particular to an automatic paper output device based on a test paper strip. Background technique [0002] Various test papers are widely used in applied chemistry and biomedicine, especially for simple chemical analysis and biological determination. The main principle is to attach the indicator to the test paper. When the tested liquid touches the test paper, the elements in the tested liquid react chemically with the indicator on the test paper, making the test paper display corresponding characteristics, mostly color changes. At present, there are mainly two types of packaging forms for test paper. One way is that each piece of test paper is individually packaged, such as figure 1 As shown, this packaging method is convenient to use, and can isolate the mutual contamination between the test papers, preventing the test papers from becoming invalid after being exposed to the air for a long ...
