Analysis Of The Cause Of Abnormal Operation Of Rewinder.

Rewinding machine is a kind of special equipment for paper, film, etc., which is used to rewind the paper roll produced by the paper machine (called the base paper roll) in turn, and the paper is made into finished paper after rewinding. At present, AC transmission instead of DC transmission has become a development trend in the paper machinery industry.
The paper roll rolled by the rewinder is relatively soft, the inside may be damaged or broken, the edges on both sides are not neat, and the width of the paper web can not be directly used in paper processing or printing machines. Most types of paper (such as newsprint, letterpress printing paper, wrapping paper, etc.) must be cut, slitter, joint, and rerolled on the paper core to form a certain specification and a certain tightness of the finished paper roll before leaving the factory.
Common anomalies of the rewinder 1, line up, the core tube length is correct, the core tube down to the front section of the track, the car does not push the core tube to the corresponding position in the back section, the core tube backlog in the front section, automatic tube stop. Abnormal cause: unknown (no abnormality in instrument control inspection), solution: this batch of manual tube, online tool change, change the platoon sequence, or change the width ±1-2mm(usually the latter is selected for the convenience of the core tube operator), and then reset, and then the next batch of automatic tube
General online knife change can be once, this class at most tried continuous online knife change 3 times, the last class use normal, suspected may be the process of the problem.
The common anomaly of the rewinding machine is two, the tool is correct, the core tube has reached the ready position, the induction limit is also, the core tube is sensed, but it does not begin to automatically lower the tube. Solution: Reset, this batch of manual tube, online tool change, change the tool successfully manual tube, check whether the limit near the position of the tube trolley is interfered with paper damage, check OK, start, accelerate and then reset, automatic, it should be OK.
The operator on the tube too fast, did not pay attention, in the case of a tube in the track, reset the empty data, and automatically next a batch of core tubes, resulting in the tube push car motor protection alarm. Don't worry. After the paper is off, remove all the core tubes in the track
Out, on the inside touch screen to manually push the tube trolley to the initial position, the exception is removed.
