Problems solved by technology

[0004] At present, air separators in the industry generally adopt the methods of positive pressure sorting, negative pressure sorting and positive and negative pressure combined sorting, but no matter which way, the wind force is constant. When the wind force is too small, some shredded tobacco cannot be separated. When the wind blows, it will be separated together with the sundries, resulting in a waste of raw materials; when the wind is too strong, some tobacco stems or other sundries will also be blown up by the wind and transported to the next stage of the process, which cannot screen and purify the shredded tobacco. effect, resulting in a decline in the quality of silk

Abstract

The invention discloses a power automatic adjusting device and method for a winnowing machine. A feeding vibration groove is arranged at the front end of a feed inlet of the winnowing machine, the front end of the feeding vibration groove is connected with an electronic belt scale, an infrared moisture meter is arranged near the feeding vibration groove, a detecting portion of the infrared moisture meter is aligned with the feeding vibration groove, an air inlet is formed below the feed inlet of the winnowing machine, the upstream pipeline, connected with the air inlet, of an air return pipeline is provided with a positive pressure fan, the tail end of the air return pipeline communicates with an air outlet of the winnowing machine, the downstream pipeline close to the air outlet is provided with a negative pressure fan, the position, close to the air inlet, of the bottom of the winnowing machine is provided with an impurity outlet, the position, away from the air inlet, of the bottomof the winnowing machine is provided with a discharge gas lock, and the electronic belt scale, the infrared moisture meter, the positive pressure fan and the negative pressure fan are all connected with a controller. The power automatic adjusting method comprises the steps of setting of basic materials, collection of real-time data and automatic adjusting. The power automatic adjusting device andmethod can adjust wind power according to practical conditions so as to achieve precise separation of cut tobacco and impurities. The device is simple in structure, and the method is easy and convenient to operate and easy to implement.

Description

technical field [0001] The invention relates to an automatic wind force adjustment device and adjustment method of a winnowing machine, and belongs to the technical field of control of tobacco shredded equipment. Background technique [0002] Tobacco winnowing machine is widely used in the tobacco industry's shred production line. During the tobacco shred making process, the winnowing machine uses the aerodynamic principle to separate the shredded tobacco from tobacco stems, gravel and agglomerates by using the density of light and heavy materials. To achieve the purpose of purifying shredded tobacco and separating, recovering and reusing tobacco stems. [0003] The wind power of the air separator directly affects the thoroughness of the separation of light and heavy materials. Since the types of incoming materials before the winnowing machine are not fixed, and the moisture and flow fluctuate greatly, these factors will affect the effect of wind force on the materials. Ac...
