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 ---
1 belt roller device
The belt and stick set consists of two belt rollers with intermediate and end supports! A rubber support belt surrounds the belt roller. The inner surface of the support belt has a guiding profile that controls the operation of the belt. There is also a correspondingly concave surface on the belt roller. The belt roller has been joined together by a rocker and a hydraulic cylinder from below. The belt tension can be adjusted with a hydraulic cylinder during the winding process.
The motor drives the rear belt roller to run, and the other roller is carried by the belt. The belt roller is equipped with a hydraulic brake system. The belt roller bearing housing is lubricated with lubricating oil. The oil flow and temperature of the lubricating oil system are detected by the sensor. There is a directional blow tube between the two rolls to ensure that no space remains in the space between the two rolls. The lifting device has been installed under the belt. The lifting device is used for changing rolls. The lifting device comprises a hydraulic cylinder and a lifting plate interlocked with the rear bottom roller during the lifting process.
Belt roller unit:
1- bottom roller
2- rear belt roller
3- front belt roller
5-belt telescopic hydraulic cylinder
Principle of operation
The core is placed between the back bottom roll and the back belt roll. The paper core is supported at that position throughout the initial crimping process up to a diameter of approximately 500 mm (17.9 in). The over 500 mm (17.9 in) belt begins to support the increasing area of ??the paper roll, and the weight of the roll is reached when the paper roll is particularly large. Mainly supported by a belt.
