Double Sticky Kraft Aluminum Duct Tape Adhesive Tape Rewinding Machine

Rewinding Machine common fault - platen roller vibration
1. Proportional valve is unstable - cleaning proportional valve or replacing proportional valve
2. Damage to the top core bearing - Replace the bearing
3. The clearance between the support wheel and the guide rail of the core device is too large - Adjust the clearance (the core is clamped at both ends of the top core, 
and the eccentric shaft of the roller is adjusted to the gap between the roller and the guide rail is 0)
4. Guide rail wear - replace or repair the rail
5. Paper core deformation - Replace the paper core
6. The top core device supports the wheel bearing or the copper sleeve wear - replace the support wheel bearing or copper sleeve
7. The thickness of the paper is different - the production process is solved

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.

2.4 Pressure mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work. The paper roll slips because the paper roll is too light, and the winding is too tight because the pressure is too high until the rewinding to the later stage. In the modern rewinder system, the platen roller is automatically controlled, so that the paper can be additionally applied. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is transmitted to the pressure program control unit to calculate the pressure, so that the oil pressure in the suspension scale can be changed, thereby achieving pressure control of the platen roller.
