Auto Rewinding Machine

Design and application of constant tension and load distribution control for winder---

4 Research significance and content
Due to the application and development of frequency conversion technology and computer network technology in the field of industrial control, the establishment of AC drive control system based on field bus has become an effective way to solve the above shortcomings and limitations. Taking PLC as the control unit, the inverter is the execution unit, and the OP operation panel is the operating unit to form the all-digital field bus rewinder AC rotation control system. Based on this assumption, in order to reduce the investment, the original mechanical part and hydraulic part of the system are basically maintained, the original DC rotating system is transformed into an AC rotating system, the solenoid valve and some worn mechanical parts are replaced; and the OP270 man-machine interface is used instead of the machine. Buttons and analog meters, and a part of the mechanical buttons, so that workers can operate on the OP270 or on the console buttons, complement each other, increasing the flexibility of operation.

Belt rewinding machine design and working principle ---

2 rear bottom roller
The roller is covered with a steel shell. It maintains a dynamic balance at a speed equivalent to the design speed. The roller has a coating and a spiral groove. Equipped with hydraulic brake system. The roll outer coating is used to attempt to increase the friction between the roll surface and the paper during rewinding. Air is discharged along the spiral groove between the roll surface and the paper roll.
Vacuum drum
The rear bottom roller has a hole. Vacuum suction is generated by a blower. This facilitates paper machine threading to ensure that the cut sheet fits snugly against the roll during roll change.
(traction) platen roller device:
1-cylinder safety valve
2- Pressing roller
3- Press roller safety lock
4- Photocell
5- Pressing roller beam
6- Paper roll
The platen roller is used to hold the paper roll during the roll paper process. The pressure between the roller and the drum is adjusted by adjusting the pressure of the platen roller. The rewinding pressure affects the roll density and sheet tightness and winding force. In addition, the platen roller ensures that the paper roll is in an adapted position.
