How to improve the efficiency of toilet paper rewinding machine
Jan 01, 2018

1: the tension control of the reel: during the rewinding of a paper roll, the rewinding tension should be avoided as far as possible to ensure the uniformity of the compactness inside and outside the rewinding machine. Secondly, during the rewinding process, if the tension control of the sheet is too small, the paper roll will loose or slide on the bottom roller, causing wrinkle and paper intertwined. While the tension control is too large, it will cause the detonation or damage of the paper core. Therefore, the actual control value of the tension is kept constant during the rewinding of the paper, and it is very necessary to install a good instantaneous inertia compensatory regulator in the tension closed-loop control system.

2: the pressure of the paper roller, the pressure of the paper roller during the rewinding process, and the additional load of the paper roll provided by the paper roller at the initial stage of the rewinding, together with the front and bottom rolls, to provide a rewinding force for the roll. With the increase of the coil diameter, the position of the press roller increases gradually, and the load provided by the paper roller decreases. When the coil diameter reaches a certain value, the load provided by the paper roller is zero. At this time, it only exists as a device to maintain the position of the paper roll. The pressure control program of a paper roller must be selected according to the quality of the paper and the final diameter. In general, the pressure of the paper roller is automatically controlled according to the preset pressure curve, and the operator does not need to change it.

3: the speed difference between the front and back support rolls. The speed difference of the supporting roller forms the rewinding force, the size of the rewinding force determines the size of the paper compactness, and the rewinding force of the rewinder can increase the compactness of the paper roll.
