Rewinding Machine operation safety regulations - 

Fifth, machine maintenance and hygiene
1. After the production is completed, first adjust the governor to zero, close the program switch, and finally turn off the power of the control box;
2. Use the air duct to blow the inside and outside of the machine and the electric box, and do not place any debris such as tools in the machine and the electric box.
3. Regularly repair and maintain the rotating parts of the machine (add some amount of oil or butter)
4. The hygiene of the machine area must be cleaned.
5. The waste paper is sent to the pulping station of the designated paper mill. The original paper core is neatly stacked in the specified paper barrel stacking area according to the specifications. The leather tape, waste paper and waste paper core are placed in the designated stacking area.
6, with the machine repair to do the regular maintenance of the machine main maintenance work.

Automatic rewinding machine speed ratio adjustment method ---

4. Adjust the internal toothed chain and external chain of the main gearbox to make the transmission of the whole machine more stable. When the roll paper rewinding machine is running, it is controlled by the automatic acceleration and deceleration program to start and stop frequently, and the automatic trimming and sealing operation is completed. Therefore, the stability of the gearbox transmission ratio is high. By tightening its internal and external chains, the chain can be prevented from slipping and skipping, making the speed ratio more stable during frequent acceleration and deceleration. The tensioned upper chain of the toothed chain can be moved up and down by a tool of about 5 to 8 mm.

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.
Construction
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.
Stretching principle:
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.
