Το ποιότητα του το re -rolling μηχανή είναι κυρίως καθορίζεται από το ακόλουθο τρία στοιχεία.
1. The tension control of the rolling machine is controlled. During the re -roll, it is necessary to avoid cchange the compound tension as much as possible to secure that the seven the tightness is uniform inside and outside. Επιπλέον, if the tension of the paper is too small, it will cause the paper roll to be loose or slippery on the bottom roller, which is prone to stress και συνυφασμένο χαρτί ασθένειες όπως χαρτί σελίδες. Αν το ένταση έλεγχος είναι πάρα πολύ μεγάλο, αυτό θα προκαλέσει έκρηξη ή ζημιά στο το χαρτί πυρήνας. Επομένως, in the process of re -rolling, the actual control value of the tension is constant and the actual control value of the tension is constant and the tension -closed control system is equipped with a well -adjusted inertial compensation regulator.
2. The wire pressure of the paper roller of the paper roller, and the pressure of the paper roll during the reunion process of the paper roller is pressed. Therefore, in the initial stage of the re -roll, the paper roll is provided with additional load Work together to provide a reunion for paper rolls. With the increase of the roll diameter, the position of the paper roller gradually increases, and the load provided by the paper roller has gradually decreased, especially when the roll diameter reaches a certain value, the load provided by the paper roller is zero. At this time, it is it. It exists only as a device that maintains the location of the paper roll. The pressure control program of the paper roller must be selected according to the quality and final diameter of the paper. Therefore, under normal circumstances, the pressure of the paper roller is automatically controlled according to the pre -set pressure curve, and the operator does not need to change it.
3. The speed difference between the rolling roller before and after the re -roll machine. in particular, the speed difference between the support roller forms the re rolling force. The size of the reunion force determines the tightness of the paper roll, so as to increase the tightness of the paper roll.
