Rewinding Machine common fault - The coil is not tight during operation
1. Unwinding tension controller is not open - Open unwinding tension controller switch
2, did not press the reset button - press the reset button on the two tension controllers
3, the unwinding tension controller tension is too small - increase the unwinding tension controller output current
4, tension controller failure - contact the manufacturer
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.
Belt rewinding machine design and working principle ---
8 core filling
The core loading device supplies a paper core between the take-up rolls.
A fork-like paper core loader is mounted on the paper feed roller. The core loader includes a paper core clip and a centering tray. The core loader is hydraulically operated. The movement of the paper core clamp is operated by compressed air.
The core is placed on a tray in the core loader. It is fixed in position by the paper core clamp.
During the rewinding process, the core loader opens and the new core is advanced. When the core loader is full, the paper core clamp will run to grip the paper core. The core loader moves to the position it should wait when the paper feed roller moves. When the paper advance roller reaches the position where the paper roll is ejected, the core loader is lowered to the drop position. The core holder is opened and the core falls into the middle of the roll.
