Automatic Adhesive Tape Rewinding Machine

Rewinding Machine structure - Ejection Department
In the rewinder system, we installed the paper roll on the paper exit frame. In order to ensure that the width of the sides of the paper web is the same, we should be moving the seasoning when 
the paper roll is ejected. But the paper roll in the new structure can move with the paper exit frame,
This ensures a greater rigidity of the exit frame. In addition to manually moving the paper roll, we can also use the pneumatic, photoelectric device and electric method to adjust the axial movement 
of the paper exit frame, so that the cutting edge of the winder can be narrowed, and the manual adjustment can not be achieved. Requirements.

Guolian High Speed ??Slitting Rewinder Technical Description ---

The specific technical structure is described as follows:

3. Double curved roller section:
Mainly composed of bracket, double arc roller, worm gear adjustment device, angle gear, air motor and other devices
        After cutting the paper, it enters a set of curved roller stretching assembly, which is mainly composed of two curved rollers and an adjusting mechanism. The adjusting mechanism is driven by a pneumatic motor, and through a set of angular gear mechanism and two sets of worm gear reduction mechanisms, according to The wrap angle between the web and the curved roller needs to be adjusted at any time. The curved roller is introduced from abroad to ensure its performance. This system effectively stretches the web, eliminates wrinkles, and separates the paper rolls.
4. Automatic paper feeding department:
The guiding paper-feeding roller and the compressed air and the guiding plate are adopted, so that the paper head can smoothly and quickly and accurately complete the paper-feeding action on the uniform air cushion generated by the guiding plate and the compressed air, and between the two bottom rollers is used between the conveyor belt and the bottom roller. Friction drive, so that the paper head is close to the surface of the bottom roller, and the paper-feeding action is completed under the action of compressed air.

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.
