Single Shaft Roll Rewinding Machine

Single Shaft Roll Rewinding Machine

Rewinding Machine common fault - The platen roller does not move
1. Proportional valve is unstable. - Clean the proportional valve or replace the proportional valve to adjust the amplification signal.
2. Control failure - on-site debugging of the instrument.

Rewinding Machine operation safety regulations - 

First, the preparation work before starting
1. Clean up the dust on the machine;
2. Check the circuit of the machine (whether the circuit is damaged), whether the rotating parts (bearings, gears, etc.) are loose, whether the conveying belt is intact, whether the protective device is intact, if there is an abnormality, it needs to be replaced or reported to the workshop supervisor in time;
3. Is the amount of lubricating oil (butter, oil) of the rotating parts of the machine appropriate? Is the amount of white mineral oil on the perforating knife appropriate? If not enough, add the right amount of oil;

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.
