Online foreign matter removing device for tobacco shred making

Abstract

The invention discloses an online foreign matter removing device for tobacco shred making. The foreign matter removing device comprises a supporting machanism, a detection mechanism and a removal mechanism; the detection mechanism comprises an X-ray machine and a detection module composed of a plurality of detectors, wherein the X-ray machine is located above a conveyor belt, and the detection module is located below the conveyor belt; and the removal mechanism is located below the discharge end of the conveyor belt, and comprises a foreign matter remover and a remover bracket, wherein the foreign matter remover comprises a plurality of high-pressure nozzles, and electromagnetic valves each are arranged at the air inlet end of each of the high-pressure nozzles. The online foreign matter removing device has the advantages that foreign matters in the tobacco shred making process can be imaged and displayed so that online impurity identification and accurate removal can be more accuratelyrealized, the online identification and removal of magnetic, low-magnetic and non-magnetic metal objects can be realized at the same time, removal effect is good, precision is high, practicability ishigh, and quality of tobacco leaves and working efficiency of tobacco shred making are indirectly improved.

Description

technical field [0001] The invention relates to the technical field of tobacco foreign matter removal equipment, in particular to an online foreign matter removal device for shredded tobacco. Background technique [0002] In the production process of shredded tobacco, due to the need to go through multiple processes such as collection and drying, it is inevitable that various sundries will be mixed in the tobacco. At present, the debris on the tobacco shred production line is mostly divided into two categories: metallic and non-metallic. Among them, for metal debris, the general removal method is mostly to install a permanent magnet device on the shred line for adsorption and removal, or It adopts metal detection device and winnowing device to identify and eliminate. However, the above method cannot accurately detect low-magnetic or non-magnetic metal objects such as stainless steel, copper, aluminum, etc., and the removal effect is not satisfactory. At the same time, when...

AI Technical Summary

Problems solved by technology

However, the above method cannot accurately detect low-magnetic or non-magnetic metal objects such as stainless steel, copper, and aluminum, and the removal effect is not ideal.

At the same time, when detecting metal foreign objects, you can only detect whether there are foreign objects, and then remove the area where there are foreign objects. However, due to the different shapes and sizes of metal foreign objects, the force and range of force required for removal are also There will be a big difference. The above method adopts a unified removal method and force, and cannot perform targeted removal actions for foreign objects of different shapes. When the foreign objects are small in size, a large number of tobacco leaves will be removed at the same time with the same range of force, resulting in material waste. When the volume of the foreign matter is too large, the same force is not enough to push the foreign matter, resulting in failure to remove the foreign matter, and the foreign matter flows into the lower process with the tobacco leaves, which may cause a decrease in the quality of the tobacco leaves, or cause damage to the equipment, which greatly affects the work of tobacco shreds efficiency
