Problems solved by technology

[0003] The paper feeding mechanism of the existing filter paper smoke meter and filter paper particulate matter monitor mainly includes a motor, a transmission system driven by the motor, and a paper reel driven by the transmission system; The feeding motor and multiple photoelectric sensors are used to control the paper travel of the filter paper, and the detection of paper breakage or no paper, the structure is relatively complicated and the cost is relatively high, and the chassis of the instrument must always work at high temperature, and there are many photoelectric sensors. The probability of working damage at high temperature increases, and the stability is difficult to guarantee; it can be seen that it is necessary to improve it

Embodiment 1

[0104] refer to figure 1 and 3 According to an exemplary embodiment of the present invention, the paper-feeding mechanism for filter-paper particle detection includes: a main mounting plate 1, a filter paper positioning component 2, a pressure paper detection component 3, a tensioned paper-feeding component 4, a roll paper component 5, and a motor drive component 6 and a control device (not shown in the figure), wherein the filter paper used to detect the smoke value passes through the filter paper positioning assembly 2, the pressure paper detection assembly 3, the tension paper feeding assembly 4 and the roll paper assembly 5 in sequence.

[0105] The main mounting plate 1 is the installation basis of the paper-feeding mechanism of the filter paper type particle detection, and the above-mentioned filter paper positioning component 2, paper pressure detection component 3, tensioning paper-feeding component 4 and roll paper component 5 are arranged on the same side of the main...

Embodiment 2

[0123] In the second embodiment of the present invention, a paper-feeding mechanism for filter-paper particle detection is disclosed. The structure of the detection mechanism is different, and the other components are the same, so only the platen detection component 3 in the second embodiment will be described in detail below, and other components will not be repeated.

[0124] see Figure 5 , in the second embodiment, the paper-pressing detection assembly 3 of the paper-feeding mechanism for filter-paper particle detection includes a pull rod assembly, an upper pressing plate 38', a lower pressing plate 37', a radioactive source 33', a detector 36' and an air outlet channel 39'.

[0125] The pull rod assembly is made up of pull rod 31 ' and cross frame 32 ', and one end of pull rod 31 ' is connected with external driving device, and the other end is connected with cross frame 32 ' by hinge. A filter paper gland 35' is arranged inside the upper platen 38', and the filter pap...

Description

technical field [0001] The invention relates to the technical field of automobile exhaust detection, and more specifically, to a paper-feeding mechanism for filter-paper particle detection and a filter-paper particle detection method. Background technique [0002] At present, the exhaust gas emitted by motor vehicles and the particulate matter emitted by soot-type enterprises are the main sources of air pollution. With the rapid increase in the number of motor vehicles and the rapid development of industry, along with the rapid increase in pollutant emissions, the air in major cities across the country Serious pollution leads to frequent smog weather. It is very meaningful to protect the living environment of human beings through the detection of motor vehicle exhaust pollution and the detection of suspended particles in the air, and to restore a blue sky to human beings. [0003] The paper feeding mechanism of the existing filter paper smoke meter and filter paper particula...
