Embodiment Construction
[0013] The content of the present invention will be further elaborated below in conjunction with the accompanying drawings of the description.
[0014] Such as Figure 1-Figure 4 As shown, the intermittent dynamic weighing and metering system for small flow rate of the present invention is composed of three units: the buffer bucket 1 at the feed end, the electronic belt scale 2, and the buffer bucket 3 at the discharge end. The buffer bucket 1 at the feed end and the buffer bucket 3 at the discharge end at the feed end and the discharge end are respectively provided with a high-level photoelectric cell 4 and a low-level photoelectric cell 5 at different heights of the buffer bucket 1 at the feed end. The discharge port of the buffer bucket 3 at the feed end is equipped with a height-adjustable vertical movable door 6, and a pair of high-level photoelectric cells 4 and low-level photoelectric cells 5 are respectively arranged on the opposite sides of the buffer hopper 1 at the ...

Disclosed are a system and a method used for intermittently and dynamically weighing and measuring small flow. The measuring system comprises a feeding end caching bucket and a discharging end caching bucket which are positioned at a feeding end and a discharging end of an electronic belt scale respectively, high-material-position phototubes and low-material-position phototubes are arranged at different heights of the feeding end caching bucket respectively, the electronic belt scale is provided with a weighing device and a control system, a vertical moving door adjustable in height is arranged at a discharging port of the discharging end caching bucket, and the high-material-position phototubes, the low-material-position phototubes, the electronic belt scale and the vertical moving door are all controlled by the control system of the electronic belt scale. Start-stop of the electronic belt scale can be controlled through information of the high-material-position phototubes and the low-material-position phototubes and the control system, flow of a lower machine can be controlled by adjusting the height of the moving door, intermittent and dynamic weighting and measuring can be realized, and accurate measuring and accurate mixing can be realized without influencing preset flow of front and rear equipment, so that the problem of inaccuracy in measuring by the electronic belt scale under the condition of small flow is solved.
Description
technical field [0001] The invention relates to the technical field of dynamic weighing of materials, in particular to the technical field of dynamic weighing for small flow conditions. Background technique [0002] With the cigarette production process of major tobacco factories paying more and more attention to the loss of raw materials, the statistical requirements for rejects are becoming more and more accurate, coupled with the increase of small-scale test lines, the flow rate of rejects in both small-scale test lines and conventional silk-making lines is increasing. Very small, if a conventional electronic belt scale is used to weigh and measure, the measurement will be inaccurate because the flow rate of the material to be measured is too small and the load on the metering section is too light. Then how to achieve accurate measurement and accurate blending under the condition of small flow rate becomes a difficult problem, and a weighing measurement method that can...
