Rejecting control device for tobacco impurities

Abstract

The invention discloses a rejecting control device for tobacco impurities. The device comprises a camera set, a digital collection card, a digital signal processor, a pneumatic valve set A, a pneumatic valve set B, a pneumatic valve driving circuit and a tobacco leaf conveying belt. The camera set is used for collecting image information, the digital collection card is used for processing the image information collected by the camera set, the digital signal processor is used for receiving the information which is processed by the digital collection card, the pneumatic valve set A is used for jetting out high-speed airflow to vertically reject the impurities in tobaccos, the pneumatic valve set B is used for blowing the impurities into an impurity containing groove, and the pneumatic valve driving circuit and the tobacco leaf conveying belt are connected with the digital signal processor and drive the pneumatic valve set A and the pneumatic valve set B to work. Pneumatic valves are tightly arrayed to form a seamless connection array, in this way, the corrective rate during rejecting is increased, and the working efficiency of tobacco leaf sorting equipment is improved; the pneumatic valves jet out the high-speed airflow to reject the impurities in the tobaccos, and during detecting, speed is high, reliability is high, and normal tobacco leafs are not damaged.

Description

technical field [0001] The invention relates to a control device for removing tobacco impurities, which belongs to the field of agricultural intelligent equipment. Background technique [0002] Tobacco raw materials purchased by tobacco factories usually contain impurities such as thread, paper scraps, and plastic fragments. If they are not separated, they will be mixed into the shredded tobacco, affecting the purity of tobacco, changing the quality of cigarettes, and causing damage to the product image. Tobacco impurity removal has become a key link in the tobacco factory's shredded process. It is usually required to remove the impurities contained in the tobacco leaves before shredding, so as to improve product quality and increase market competitiveness. Considering that the impurities contained are often small in size and difficult to distinguish in color, the front-end identification of the current tobacco leaf impurity removal system often relies on CCD for image acqui...

Problems solved by technology

Industrial computers and boards are cost-effective and not easy to integrate on the production line, but the current market lacks embedded control cores to replace industrial control equipment

With the increase of control equipment required on the tobacco removal production line, it is also easy to cause performance degradation and collapse of the industrial computer
