Automatic feeding device for nondestructive testing of leafy vegetables

Abstract

The invention relates to the field of testing equipment, and discloses an automatic feeding device for nondestructive testing of leafy vegetables. The automatic feeding device for nondestructive testing of the leafy vegetables comprises a rotation transportation unit, a suction unit, a material storage unit, a power output unit and a motor control unit. The rotation transportation unit comprises a roller, the circumference of the roller is provided with multiple sets of suction holes, and a sealing unit used for blocking one set of the suction holes in the roller is fixedly arranged in the roller; the suction unit comprises a suction pump which is used for sucking air in the roller to form negative pressure on the inner side of the roller; the material storage unit comprises a material tank used for containing the leafy vegetables, the material tank is located below the roller, and when the automatic feeding device works, the leafy vegetables in the material tank are adsorbed on the outer wall of the roller under the negative pressure action of the roller; the power output unit is used for driving the roller to rotate and conveying the leafy vegetables to the corresponding position blocked by the sealing unit to fall; the motor control unit is used for controlling the rotation speed of the roller. According to the automatic feeding device for nondestructive testing of the leafy vegetables, continuous, even and automatic feeding can be achieved, and necessary conditions are supplied to optical nondestructive testing of the leafy vegetable quality.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to an automatic feeding device for non-destructive testing of leafy vegetables. Background technique [0002] my country is a big country in the production and consumption of fruits and vegetables. The output of fruits and vegetables accounts for about 20% and 49% of the world respectively, ranking first in the world. [0003] However, due to the backwardness of our country's fruit and vegetable testing equipment and imperfect testing methods, in international trade, we are often restricted by other countries' technical barriers because we cannot accurately grasp the quality and safety of fruits and vegetables. Export. Moreover, when foreign fruit and vegetable products enter my country, the toxic and harmful substances in them cannot be accurately measured, and technical barriers cannot be effectively implemented to protect the quality and safety of my country's food.
