Rewinding Machine safety operation guide -
Seventh, production operations and quality control during the rewinding process:
4, pay attention to the quality of the rewinding of the paper roll when rewinding, found zigzag, knife, running,
If the color difference is serious, skipping, chain printing, wrinkling, violent edge, etc., the result should be stopped in time. Only after the inspector confirms can the machine be re-rolled.
5. When the rewinding operation is running, the host must be at the console, and must not leave at will to prevent accidents. Transport
The speed of lifting and lowering is slow, and the speed of the vehicle cannot exceed the prescribed limit.
6. When loading the paper core tube, it is necessary to select the paper core with the same outer diameter and the length specification in line with the quality standard.
The installation of the cylinder requires a large deviation of the outer diameter and needs to be replaced.

Stretching device after cutting the web
The purpose of stretching after slitting is to stretch the sheet in the lateral direction and to separate the cut sheets from each other.
After the cut, the stretch is achieved by the wrap angle roll. The wrap angle roll includes a stretch roll. The first spreader roll is above the cut sheet and the second spreader roll is below the sheet. Both rollers are mounted on a frame that is used to adjust the stretch.
The spreader rolls above the sheet have good curvature. The spreader roll is equipped with a bend control device. The hand wheel and screw mechanism are used on the maintenance side to control the direction and tendency of the bend.
The segmented spreader rolls are under the sheet of paper. The segmented stretch roll is placed over an arcuate roll mounted on a steel beam. The cylinder is mounted below the segmented spreader roll. The bending curvature of the spreader roll can be modified by adjusting the gas pressure to adjust the cylinder.
When the sheet passes under the first roller, the sheet is guided from the center to the outside by a curved roller at each slightly different angle. At this time, there is a small gap between the cut sheets. When the sheet is placed over the second roll, the sheet encounters an arc of the opposite direction, which allows the sheet to remain parallel through the gap.
The stretching effect is mainly controlled by changing the wrap angle of the spreader roll. In addition, the stretching effect can also be controlled by changing the bow position of the stretch roll to control and change the arcuate curvature of the segmented spreader roll. The spreader roller is driven by a separate drive motor through a V-belt. The speed of the stretching roller is the same as the speed of the rewinding machine.
