How to adjust the drawing gauge of Beiren printing machine?

Cam adjustment mode under drawing gauge: left and right adjustment can control the length of paper drawing; The adjustment before and after can control the time of pressing the paper bearing.

Adjustment method of the small roller of drawing gauge: loosen the nut on the small roller shaft and turn the small shaft (eccentric). You can see that the distance between the small roller and the cam under the drawing gauge has changed. The closer the distance is, the longer it takes to draw paper and the farther the distance is.

Adjustment method of paper pressing bearing: just adjust the eccentric shaft, which is the control room to control the height of the drawing gauge plate, just like the adjustment method of the drawing gauge small roller.

Adjustment method of the paper pressing force of the paper pressing bearing: Just adjust the tension nut of the press spring, and pressing it down means applying force, and loosening it means releasing force.

Adjust the relationship between the swinger and the front gauge.

When the front gauge blocks the paper, pull the gauge to pull the paper. The lifting time depends on the turning action of the oscillating teeth after biting the paper, but when the paper is not moving, the paper pressing roller of the gauge should be lifted. No matter how it is adjusted, the front gauge, the drawing gauge and the movable teeth must have a place where the paper can be held steady, so that the rules can be accurate.

Height adjustment of gauge plate: put the thickness of printing paper +80g offset paper (or 157g coated paper) under the gauge plate for adjustment, and just slightly tighten it.
