Rewinding Machine common fault - The platen roller does not move
1. Proportional valve is unstable. - Clean the proportional valve or replace the proportional valve to adjust the amplification signal.
2. Control failure - on-site debugging of the instrument.
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.

5：Unloading table action
1- Unloading table rise position
2- Middle position of the unloader
The unloading station transfers the paper roll from the winder to the ground.
The unloader is a device mounted on the floor to remove the paper roll. The platform is controlled by a hydraulic cylinder. The platform is a steel structure. The platform hydraulic unit is equipped with a load relief valve. These are to ensure the control process of the unloading roll.
When the paper roll is advanced onto the platform in the upper position, the platform unloads the paper roll to the intermediate position and then onto the floor, and the paper roll rolls off the platform. For safety reasons, the platform will not automatically unload paper onto the floor unless it is moved by the operator from the intermediate position to the unloading position. The reel cannot be unloaded to the floor anyway before the new rewind.
