Rewinding Machine safety operation guide -
Third, the rewinding machine opening and closing operation sequence:
2. When the paper roll reaches the specified rewinding diameter (meters), the working speed will slowly drop.
After the paper roll reaches the specified diameter (meters), press the “stop” switch. After the quality inspector has measured the paper roll and the appearance quality, tape the outermost piece of paper with a tape and stick the paper. The inner core of the core barrel is pulled out (the thimble) and the bottom knife roll is lifted to remove the paper roll.
3, the rewinding machine should have a long downtime, stop the paper side fan, and do a good job of surrounding sanitation.
Rewinding Machine operation safety regulations -
Fourth, other requirements in the production process：
5. When an abnormality or malfunction occurs in the production process, the machine must be turned off and checked and repaired. If the abnormality or failure is not handled, the workshop supervisor should be reported in time;
6. The perforation line must be inspected every half hour during the production process. If the perforation line is unqualified, it must be shut down immediately;
7. Every paper change must be weighed twice in the production process. If the weight of the original paper is quantitative, the texture and elongation are unstable, the number of knots should be adjusted at any time, the pressure of the riding stick should be adjusted, and the gearbox should be adjusted. The paper is elastically adjusted to meet the product diameter requirements, and the weighing is tracked to see if the weight of the product meets the standard.
8, at any time to patrol the quality of the product.
Rewinder mechanical structure and control process ---
Second, the main structure of the winder
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.
