Slitter Rewinder For Paper

Slitter Rewinder For Paper

Maintenance of the winder
1. The transmission of the toilet paper rewinder, such as the gear chain, needs to be added with butter.
2. The rewinding machine generally does not have problems. The consumable parts are nothing more than small pinions. If one is added, the printing knife is easy to break. The wool roller will become thinner after one and a half years of loading, and it needs to be transported back to the factory for renovation. If the embossing pattern needs to be replaced in the steel roll embossing device, it is necessary to transport the steel roll back to the original factory for modification, and it will not cost much.
3. Pay attention to the voltage of the winder should be stable, otherwise it is easy to burn the motor; pay attention to hygiene, do not let the debris fall between the steel roller and the roller.

2.1 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. However, the paper roll in the new structure can be moved together with the paper exit frame, which ensures greater rigidity of the paper 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.
We have a coupling on the reel of the unwinding roll. When working, we can use a pneumatic device to connect the brake to the motor. We can know that when the high-speed winder is started, the required acceleration time from zero to 2000m/min can be completed within 50~60s, and the deceleration time required for braking is 40s. Or even shorter, so we need to consider the maximum diameter and the maximum braking speed of the paper-removing brake on the winder to reduce the paper loss of the paper-cut, or it will cause a lot of waste. In the selection of the brakes of the eject roll, we often use brakes for starting brakes, magnetic brakes and mechanical brakes. In the usual case, we use the combination of the brake motor and other brake devices. When we press the paper, the paper roll started by the DC motor can enter the acceleration and working state and can be operated by the braking of the DC motor. Control, the tension control of the paper web, in the case of emergency stop, we can use the DC motor and other brakes together to stop the paper roll at the fastest speed.

2.2 Longitudinal section
In the mechanical system of the winder, the slitting mechanism is a very important part of the winder. In order to ensure a straight and smooth cutting edge, the quality control of the finished paper roll plays an important role in ensuring the volume. It is easy and can reduce the fluffing during printing. The slitting mechanism should be installed as close as possible to the paper roll so that it can produce a lateral movement more than necessary during the process of cutting the web without curling.
The high-speed rewinding paper conveying system is also very important in the application. The old-fashioned rewinding machine is mainly handled by manual. With the increase of the speed of the rewinding machine, the manual can no longer be processed. There are two ways to transport the paper side of the reel: fan direct pumping and venturi suction. The direct drawing type of the fan mainly uses a centrifugal fan, and the fan is placed under the floor. The inlet of the fan and the air duct near the longitudinal cutting edge are connected to each other, and the blade of the fan is also equipped with a wind blade. When the fan is sucked, it will be broken by the blade and then sent to the water pulper. However, since the edge of the paper has to pass through the inside of the fan, the blade transported by this type of paper is very worn and needs to be changed frequently. Venturi suction is also used in the high-pressure centrifugal fan, but the paper edge does not pass through the fan, directly the longitudinal cutting edge of the duct into the venturi pipe, the wind machine generates negative pressure in the venturi, and then the paper While washing the venturi tube and then feeding it to the water pulper, the paper edge conveyed at this time is continuous. The disadvantage of this method is that when the speed of the winder is relatively high, the power of the selected fan is large, which will increase the operation. Cost, increase loss.
