Rewinding Machine common fault - The coil is not tight during operation
1. Unwinding tension controller is not open - Open unwinding tension controller switch
2, did not press the reset button - press the reset button on the two tension controllers
3, the unwinding tension controller tension is too small - increase the unwinding tension controller output current
4, tension controller failure - contact the manufacturer
Guolian High Speed ??Slitting Rewinder Technical Description ---
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.
Design and application of constant tension and load distribution control for winder---
1. Rewinder structure and working principle
The rewinder is generally composed of a unwinding roll (also referred to as a paper take-off roll), a guide roll, a slitting mechanism, a platen roll, a take-up bottom roll (including a front bottom roll and a rear bottom roll), and a double bottom roll. The machine is characterized by two rotating drums to replace and support the take-up reel, usually with or without a rotating platen roller pressed against the top of the reel in the take-up, the take-up reel is taken up The main structure (has become the front and rear bottom rollers respectively). Under normal circumstances, the surface of the front bottom roller is rough, and the surface of the rear bottom roller is relatively smooth. They are connected to the motor through the reduction gear box. The platen roller, also called the load roller, acts to create a downward pressure whose pressure is the difference between its own weight and the load roller lifting pressure. The unwinding roller is composed of a leg paper holder, a unwinding roller coupling, a unwinding roller clamping mechanism, and a unwinding motor. Longitudinal cutters generally have book holders side by side on the same axis, mainly used to cut off the change. Cut a certain width of sheet paper to the required width as needed. Two tension sensors are placed on the tension roller to receive the web tension.
