Rewinding Machine safety operation guide -
Seventh, production operations and quality control during the rewinding process:
1. The speed must be slow when rewinding, and the inspector should check the appearance quality of the paper.
2, often check the quality of the paper, found that the paper disease stopped in time, to the inspector on duty
Report and contact the upper and lower processes to strip off paper with quality problems. The rewinding can be continued after the inspector confirms.
3. When rewinding, pay attention to the situation of broken ends, trimming, etc., and control the tension of the paper during rewinding.
The car is tight) to keep the inner and outer tension of the paper roll consistent.

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 ---
rear bottom roller
The movable beam is fixed to the frame. The movement of the platen roller beam moves with the hydraulic cylinder attached to the beam. The platen roller is decoupled from the hydraulic cylinder during the rewinding process. The platen roller also includes a pressure sensor to measure the pressure between the platen roller and the frame.
The platen roller has a position measuring device for providing a position about the platen roller and the diameter of the paper roll. Based on the above information, the hydraulic cylinder moves in accordance with the separation design curve as the diameter of the paper roll continues to increase. The hydraulic cylinder is equipped with a hydraulic hose rupture protection valve to prevent the paper roll from suddenly falling when the hose is damaged.
The platen roller provides additional load to the paper roll at the beginning of the rewinding. At a later stage of the rewind, the pressure is released. In the final stage, the platen roller ensures that the paper roll is in place.
During the threading and changing process, the platen roller is raised to the rear of the safety lock at the top position. The safety lock prevents the platen roller from suddenly falling when the device malfunctions. The platen roller is automatically decompressed when the platen roller is lowered to the core or the base. If the lowering control is terminated before decompression, the platen roller will be activated and the platen roller will be raised to the upper position.
During the rewinding process, the contact surface between the platen roller and the paper core must be carefully observed. If the platen roller is very close to the core, special care must be taken during the rewinding process. If the core starts to vibrate, the speed must be lowered immediately. There is a vibration indicator on the pressing roller beam to facilitate speed reduction in that case.
