Rewinding Machine safety operation guide - 

Third, the rewinding machine opening and closing operation sequence:
1. Start the rewinding machine and the paper edge blower motor to put the speed to the crawling speed. Tearing the web
Into one. The paper edge is wound into a roller according to the specified path, and the round paper web must be straightened. Loosen and tightly adjust, press the switch and the paper core tube to stick the tape. Stick the paper web to the paper core tube and start crawling. At the same time, the end of the paper roll is flat. The paper can not be wrinkled or discounted to ensure the quality of the rewinding. When the paper has broken ends, the joints are operated, the broken ends are connected and the joint quality is ensured.

Automatic rewinding machine speed ratio adjustment method ---

2. Adjust the paper-pressing gap of the platen roller so that the paper web can be smoothly conveyed between the paper feeding belt and the winding roller. The rear platen roller is the intermediate link of the paper web conveying process. If the adjusted gap is too small, the paper web is easy to wrinkle and sag. When the gap is too large, the three layers of paper are not combined together to facilitate delamination and fault, which affects the speed of the paper feed and Rewind quality. When adjusting the paper-pressing roller, the paper-pressing gap should be gradually increased from small to large, so that the paper web can be locked without sag and not drooping.

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.
