An automatic reset cleaning device

Abstract

The invention relates to an automatic resetting and material clearing device, and belongs to the technical field of tobacco conveying. When a driving chain drives a material clearing roll, the material clearing roll swings front and back along with the outlines of profile modeling wheels under the action of a following mechanism and depended wheels and compresses the profile modeling edges throughcompression springs, the purpose that the material clearing roll can make zero-clearance contact with a passing conveying mesh plate at any position is achieved, and material leakage is prevented; inthe working process, the driving chain also can swing front and back along with the following mechanism, the swinging range is wide, and the tightness degree of the driving chain can be greatly changed in the process; and in order to enable the driving chain to not skip teeth in the swinging process and keep the tightness degree invariable so as to conveniently and normally drive the material clearing roll and ensure normal conduction of equipment production, a driving tensioning mechanism is arranged to achieve a tensioning function of the driving chain, the whole material clearing device iscompact in structure and reliable and stable in driving, and material leakage is prevented. According to the automatic resetting and material clearing device, the effects are significant, the practicability is achieved, the actions are flexible and reliable, and economic losses caused by material leakage are completely eradicated.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf conveying, and in particular relates to an automatic reset cleaning device. Background technique [0002] At present, most of the cleaning equipment for conveying screens of re-roasting machines at home and abroad adopt fixed independent drive mode to realize the function of cleaning the conveying screens and bringing back the tobacco leaves, keeping the conveying screens clean and free of residual tobacco leaves. However, since the installation position of the cleaning roller is at the arc-shaped turning of the conveying screen, the turning curve is not a continuous smooth arc line, but a segmented (width is the width of the screen) passing through the turning. The convexity is the largest, and the cleaning roller is pushed out to the largest distance. Then when the third block passes through the cleaning roller, the cleaning roller falls back to the lowest point by its own weight. In this c...
