Rewinding Machine operation safety regulations -
First, the preparation work before starting
1. Clean up the dust on the machine;
2. Check the circuit of the machine (whether the circuit is damaged), whether the rotating parts (bearings, gears, etc.) are loose, whether the conveying belt is intact, whether the protective device is intact, if there is an abnormality, it needs to be replaced or reported to the workshop supervisor in time;
3. Is the amount of lubricating oil (butter, oil) of the rotating parts of the machine appropriate? Is the amount of white mineral oil on the perforating knife appropriate? If not enough, add the right amount of oil;

Second, the system configuration
1. Main transmission part: 1 set of paper-removing brake generator, 400kW (YVP4501-6 or
1LA8357-6), one roller motor (YVP225S-4), 37kW, two pressure roller motors (YVP132S-4), 5.5kW, two coiling motors (YVP355L2-4) (one for each front and rear roller) , 315kW, 6 paper cutter motor, 0.55kW, total installed capacity 1082kw (model and power are subject to final design). The rectification feedback and the inverter unit and the tension controller matched with the above constitute a transmission control system.
2. Logic control part: PLC host 1 block.
3. The logic control system selects the S7-400 series products of SIEMENS.
4. Tension control part: 1 set of tension detection and control system, using Sweden
5. 1 set of coiling roller pressure detection and control system.
6. The diameter detecting sensor of the take-up roller.
7, with position detection, pressure detection, liquid level detection, safety detection sensor and phase
The control agency should be controlled.
8. On-site operation panel, logic control panel, and electric drive panel.
Belt rewinding machine design and working principle ---
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.
