Four release and one rewinding machine operation program ---
First, prepare for inspection before starting the machine
1. Dust removal: Before cleaning, ensure that the work area is cleaned and there is no dust. There is no dust on the shaft. Clean it once with an air gun to remove the dust.
2, the direction of receiving and discharging: When unwinding the bar, pay attention to the direction of feeding. The discharge stick is counterclockwise. The receiving stick is clockwise.
3. The position of the gear and the position of the barrel are placed: the gear of the discharging stick and the receiving stick should be in the middle of the gear of the motor, avoiding the friction between the gear and the gear around the gear during the fine adjustment, thus causing damage to the gear or the motor; The receiving barrel should be the same on the scale of the stick.
4. Inflatable locking: After the position of the barrel is placed, use a high-pressure air gun to ventilate each barrel to ensure that each barrel is locked. (It is strictly forbidden to start the machine without inflation)
5. Induction: Manually pass the materials through the intermediate rollers and the tension sensor in sequence, and finally wrap the receiving core and fix the material head by hand. Note: Ensure that the material is neat and flat during the process of fixing the material. Put the material well and press the pressure shaft on the receiving roller.

3. Adjust the curved shaft behind the punching knife. The curved shaft is finally stretched as a smooth transition axis before the web is wound up. The position of the position and the working arc size not only affect the smoothness of the paper web, but also affect the stability of the web transport. When the curved axis is too high, the paper web is scratched by the punching surface knife, and the jitter is large and the paper is easy to break. When the position is too low, the paper web is scraped to the low hole and the broken layer is easy to break. Generally, the height of the curved shaft position is adjusted so that when the paper web passes through the punching knife, the bottom layer is preferably 5~8 mm higher than the punching bottom knife, and the working arc of the curved shaft is as small as possible, and the paper can not wrinkle.

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.
