Rewinding Machine safety operation guide - 

Fifth, the tool change operation:
1. The bottom knife replacement is handled by the mechanic.
2. The rewinding machine must be stopped when the upper round knife is replaced.
3. After removing the round blade, replace the new blade and fix it.
4. Install the round knife seat, adjust the angle, and lower the round knife to make it close to the bottom knife.
5, running, paper test knife, paper edge is not, smooth.
6. The tightness and depth of the blade and the bottom knife should be controlled properly, not too tight, otherwise the new knife
The film will roll the knife; it should not be too loose, otherwise it will jump the knife and the hair; not too deep, otherwise it will cause double trimming; too shallow will jump the knife.

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.

Design and application of constant tension and load distribution control for winder---

4.1 Research significance
The significance of this paper is to apply advanced field bus and frequency conversion technology to the traditional paper industry, making the rewinder control system very practical and advanced for a long time.
Firstly, the new Profibus field bus is used to replace the system's large number of I/O wiring, which effectively avoids the interference of the signal; the OP operation panel is used to replace the analog secondary instrument and switch button of the original system. The control system is divided into two levels: the monitoring machine (operator panel) and the field control level (lower position machine). Through the system, the operator can timely understand the various operating states of the winder through the OP panel, analyze the cause of the fault, and make corresponding adjustments and controls on the OP panel according to the site conditions in time. The new control system adopts the frequency conversion control technology, which abandons the DC rotation control mode of the original system of the winder. The application of the frequency conversion technology improves the speed and control precision of the system. The modified vehicle speed reaches 1200m/min (line speed), which is the original system. Twice, at the highest speed, the speed error does not exceed 2%. The friendly man-machine interface system can effectively control the entire production process of the winder, realize effective control of key production parameters, ensure safe and stable production, improve economic efficiency, and reduce labor intensity of workers.
Secondly, the implementation scheme of the new control system has strong universality. The software and hardware design and transformation of the general data acquisition system can connect the original system to the field bus, and the design of the tension and load distribution control of the winder The equipment transformation in the paper industry and the cigarette industry has certain reference significance.
