Rewinding Machine common fault - platen roller vibration
1. Proportional valve is unstable - cleaning proportional valve or replacing proportional valve
2. Damage to the top core bearing - Replace the bearing
3. The clearance between the support wheel and the guide rail of the core device is too large - Adjust the clearance (the core is clamped at both ends of the top core,
and the eccentric shaft of the roller is adjusted to the gap between the roller and the guide rail is 0)
4. Guide rail wear - replace or repair the rail
5. Paper core deformation - Replace the paper core
6. The top core device supports the wheel bearing or the copper sleeve wear - replace the support wheel bearing or copper sleeve
7. The thickness of the paper is different - the production process is solved

4. Tension control part: 1 set of tension detection and control system, using Sweden
5. 1 set of coiling roller pressure detection and control system.
6. The diameter detecting sensor of the take-up roller.
7, with position detection, pressure detection, liquid level detection, safety detection sensor and phase
The control agency should be controlled.
8. On-site operation panel, logic control panel, and electric drive panel.
Automatic rewinding machine speed ratio adjustment method ---
The rewinding machine is the first station of the production line equipment of the welcoming machine. The good running condition of the rewinding machine directly affects the quality and production efficiency of the post-processing welcoming paper. The rewinding machine should be able to operate normally and in a good production state. In addition to the good and non-damage of the components, the reasonable adjustment and control of the transmission ratio of the whole machine is very important.
When the rewinding machine is produced, the original paper web is conveyed by five transmission rollers and belts, that is, a paper feeding belt, a curved roller, a rear platen roller, a front platen roller, a winding roller, and the like. Each of the base papers is thin, the elongation is limited, and the transmission speed ratio is unstable, and the paper web is easy to wrinkle and be broken during the continuous acceleration and deceleration operation of the winder. Reasonable adjustment and control of the speed of each drive roller and paper feed belt can greatly reduce the phenomenon that the paper web is broken. After many daily adjustments, the author summarizes the following key adjustment methods. 1. Stable paper feed belt conveys the line speed of the original paper web. The paper feeding belt of the rewinding machine is driven by the V-belt through the stepless speed-regulating wheel. When the output torque is large, the driving V-belt is close to the outer edge of the speed-regulating wheel, and the transmission speed will be more stable. In order to achieve such a stable transmission effect, the speed ratio of the main gearbox can be adjusted step by step to make the speed of the winding roller slower, and at the same time adjust the speed control handwheels of the paper feed belt of the original paper frame, so that the three sets of transmission triangle belts are in The outer edge of the stepless speed regulation wheel is in a reasonable position until the winding speed of the winding roller and the paper feeding belt are the same.
