Tobacco leaf metal foreign body removal device used for threshing and redrying

Abstract

The invention discloses a tobacco leaf metal foreign body removal device used for threshing and redrying. The tobacco leaf metal foreign body removal device comprises a material return device, a cylinder component, a support, a material falling barrel, a metal foreign body separation belt conveyor, a belt conveyor, a rear end belt conveyor and a control device. The material return device and the cylinder component are each installed on the support. The support is arranged on a support of the belt conveyor. The material falling barrel is arranged below the discharging end of the belt conveyor.The rear end belt conveyor is arranged on one side of the material falling barrel. The metal foreign body separation belt conveyor is arranged below the discharging end of the material falling barrel.The material return device, the cylinder component, the material falling barrel, the metal foreign body separation belt conveyor, the belt conveyor and the rear end belt conveyor are all electricallyconnected with the control device. By means of the tobacco leaf metal foreign body removal device, automatic high-speed and high-precision removal can be conducted on non-tobacco metal foreign bodiesor defective products in tobacco materials, influences caused by containing of the metal foreign bodies to product quality are reduced, the product quality is ensured, the production cost is reduced,and the production efficiency is improved.

Description

Technical field [0001] The invention relates to a foreign matter removal device, in particular to a metal foreign matter removal device for threshing and redrying tobacco leaves, belonging to the technical field of tobacco leaf processing and manufacturing threshing and redrying. Background technique [0002] At present, in the threshing and redrying industry, for redrying enterprises, the content of impurities in the redrying finished tobacco has always been the concern of industrial customers, and industrial customers have more and more requirements for the control of impurities in the redrying finished tobacco. In the redrying process of tobacco leaves, some foreign objects with large volume or weight can be removed by manual selection, sand screening equipment and winnowing and impurity removal equipment, but for some metal foreign objects, they need to be detected by metal detectors. After the material is returned by the return belt conveyor, the material enters the collecti...

Problems solved by technology

[0003] With the traditional return device, on the one hand, the motor needs to be reversed to drive the belt to reversely output the metal-containing tobacco leaves to the collection frame. For some spherical metal foreign objects, it takes a relatively long time to return the material, and the returned tobacco leaves Tobacco leaves containing metal foreign matter are collected by the collection frame and then manually picked up many times to remove the metal foreign matter. The workload of picking up is large, and the efficiency of picking up metal foreign matter is low
