Technical Field

The invention belongs to the technical field of cut stem mechanical equipment, and particularly relates to a method and a device for adjusting a press roll gap.

Background

The stem presser is a key device for processing cut stems, and after the tobacco stems are rolled by the stem presser, the shapes of the tobacco stems are changed, and the tobacco stems become thin and wide. The stem pressing equipment used at present generally comprises a fixed pressing roller and a movable pressing roller which are parallel to each other, the fixed pressing roller is fixed on a stem pressing machine frame and cannot move back and forth, and the fixed pressing roller drives a roller shaft to operate through a direct connection speed reducing motor. The rotating direction of the dynamic pressure roller direct-connection speed reducing motor is opposite to that of the fixed pressure roller, and the tobacco stems are continuously extruded by the two rollers to deform when passing through the gap between the two rollers.

Because the two compression rollers of the stem presser have large volume and high weight, if the compression roller gap is adjusted by the traditional pure gear machinery, the gear adjusting mechanism is complex, the adjusting and converting direction and times are more, and the adjusting amount is measured by the scale value on the rack, the adjusting method has long time and large labor amount, and the compression roller gap is not easy to adjust or the adjusting value is inaccurate. If the gap between the compression rollers is not uniform and stable, the thickness of the extruded tobacco stems is not uniform, the cut stems are more, the cut stems are thicker, and the stems are not easy to be mixed in high-grade tobacco shreds.
