Rewinding Machine operating procedures - Start thread
1The main operator passes the inspection to confirm that the paper core and the size of the paper cut are correct.
The power-on signal informs the operator to prepare the paper. Open the paper feed roller, blower system, and paper positioning system before threading.
2. Start the rewinding machine and crawl the car at a speed of 15 meters.
3. The base paper is torn or folded into a triangle and sent to the platen roller to be delivered by the platen roller.
The paper is fed to the bottom knife roll and pressed against the horizontal roller.
4. The paper web is drawn flat and the paper trimming is aligned with the paper core and the port.
Introduce the paper edge fan to inform the main operation to stop. At this time, check the trimming situation and adjust it in time.
5. Use a piece of tape to match the paper web to the paper core, and then remove the letter immediately after sticking.
No. To inform the main operation, press the platen roller button to press the platen roller against the paper core, and start the roll paper.

Rewinding machine unwinding tension control system design ---

       This paper presents the design scheme of the rewinding electrical control system of the main drive for the DC motor, including the overall control scheme of the system, the control of the web unwinding tension, the control and establishment of the key quantity mathematical model and the selection of the main drive motor. type.
       Web tension control is one of the most important factors in ensuring the shape of the paper roll. The most important function of the web tension is to flatten the paper web, while the stable web tension will also avoid lateral deflection of the web. In the rewinder, the web tension is generated by the eject roller drive motor operating in the feedback brake state. The magnitude of the web tension, or the stability of the tension, lies in the control of the exit roller motor. For the tension control scheme, the control systems of domestic rewinders can be roughly divided into two categories: direct tension control scheme and indirect tension control scheme. From the control scheme, the so-called direct tension scheme uses the measured tension as the feedback signal. Compared with the given signal, the tension adjuster is used to adjust the tension. The advantage of this scheme is that the control structure is simple and the control response is rapid, but it is difficult to balance the rapidity of control response and the stability of control. The so-called indirect tension control scheme is to analyze the cause of the tension change, and compensate the main disturbance amount. If several disturbances can be controlled at the same time, good results can be achieved. Taken together, direct tension control should be combined with an indirect tension control scheme to take advantage of its fast response while avoiding other deficiencies.
       The selection of the main drive of the rewinding machine should mainly consider whether the three main aspects of the speed regulation range, power and torque of the motor meet the requirements. Of course, the cost and the coordination with the gearbox should be considered comprehensively to achieve the best cost performance. The paper gives an example of the hardware selection of the system for specific tension control requirements.

Automatic rewinding machine speed ratio adjustment method ---

3. Adjust the curved shaft behind the punching knife. The curved shaft is finally stretched as a smooth transition axis before the web is wound up. The position of the position and the working arc size not only affect the smoothness of the paper web, but also affect the stability of the web transport. When the curved axis is too high, the paper web is scratched by the punching surface knife, and the jitter is large and the paper is easy to break. When the position is too low, the paper web is scraped to the low hole and the broken layer is easy to break. Generally, the height of the curved shaft position is adjusted so that when the paper web passes through the punching knife, the bottom layer is preferably 5~8 mm higher than the punching bottom knife, and the working arc of the curved shaft is as small as possible, and the paper can not wrinkle.
