Example Embodiment
[0019] The present invention will be described in detail below with reference to the drawings, and the method of utilizing wind inertia principles is improved, including the steps of the following steps:
[0020] S1: Based on the principle of wind inertia separation, the specific position of the wind conveying photoelectric sorting equipment is designed with a plurality of arc curved curvone pipes for the hierarchical distribution of tobacco destinations;
[0021] S2: The image recognition apparatus and the spray culling device are arranged at the arc curved pipe, and the separation port is opened in the position of the spray shotting device; the related equipment is activated, i.e., sorting the tobacco material.
[0022] Such as figure 1 As shown: This example also discloses an apparatus using a wind inertial principle to improve the inertiatable tobacco grade, including a main fan 1, and a wind conveying conduit 2 with the main fan, the wind conveying conduit away from one end o...

The invention discloses a method and equipment for improving the grade of sorted tobacco leaves by using a wind inertia principle. The method comprises the following steps that S1, based on a wind inertia separation principle, a plurality of sections of arc bent pipelines for layered distribution of tobacco leaf materials are designed at specific positions of a wind conveying pipeline; and S2, an image recognition device and a blowing removal device are arranged at the arc bent pipeline. The equipment comprises a main fan and a wind power conveying pipeline communicated with the main fan, wherein the wind power conveying pipeline is provided with a plurality of sections of arc bent pipelines, and the arc bent pipelines are provided with image recognition devices and blowing removal devices. By the adoption of the method and equipment, image recognition precision and the compressed air injection removing effect of the photoelectric automatic intelligent leaf selecting and impurity removing equipment are improved, a phenomenon that tobacco leaves meeting the grade are removed by mistake is reduced, it is ensured that low-grade tobacco and non-tobacco impurities are reliably removed, and the grade qualification rate and purity of the tobacco leaves meet the technological requirements.
Description
technical field [0001] The present invention relates to the technical field of tobacco processing equipment, in particular to the technical field of on-line photoelectric automatic intelligent sorting of tobacco leaves and the technical field of equipment used in the production and processing of threshing and redrying, and in particular to a method for improving the grade of air-selected tobacco leaves by using the principle of wind inertia Methods and equipment. Background technique [0002] In the wind-driven photoelectric automatic leaf selection and impurity removal equipment of the existing threshing and re-baking production line, due to the fast moving speed of the tobacco leaf materials (mainly tobacco leaves and tobacco sheets) through the vertical pipe or horizontal pipe, and the distribution in the pipe Disorganized (in severe cases, the material exceeds the focal length range of the lens of the image processing system, resulting in blurred and unclear images), and...
