Rewinding Machine common fault - Rolls are not collected
1. The original coil is not uniform - Finish the original coil to ensure that the original coil is neat
2, paper core size head - check the paper core
3, only start a short period of time - normal phenomenon,
4, bearing damage - bearing damage is often accompanied by abnormal noise, pay attention to check the bearing, found that the damage is replaced in time
5, shaft damage - contact the manufacturer

Rewinding Machine safety operation guide - 

Seventh, production operations and quality control during the rewinding process:

4, pay attention to the quality of the rewinding of the paper roll when rewinding, found zigzag, knife, running,
If the color difference is serious, skipping, chain printing, wrinkling, violent edge, etc., the result should be stopped in time. Only after the inspector confirms can the machine be re-rolled.
5. When the rewinding operation is running, the host must be at the console, and must not leave at will to prevent accidents. Transport
The speed of lifting and lowering is slow, and the speed of the vehicle cannot exceed the prescribed limit.
6. When loading the paper core tube, it is necessary to select the paper core with the same outer diameter and the length specification in line with the quality standard.
The installation of the cylinder requires a large deviation of the outer diameter and needs to be replaced.

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.
