Rewinder For Adhesive Tapes

Rewinder For Adhesive Tapes

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

Design and application of constant tension and load distribution control for winder---

1. Rewinder structure and working principle

1.1 Structure
The rewinder is generally composed of a unwinding roll (also referred to as a paper take-off roll), a guide roll, a slitting mechanism, a platen roll, a take-up bottom roll (including a front bottom roll and a rear bottom roll), and a double bottom roll. The machine is characterized by two rotating drums to replace and support the take-up reel, usually with or without a rotating platen roller pressed against the top of the reel in the take-up, the take-up reel is taken up The main structure (has become the front and rear bottom rollers respectively). Under normal circumstances, the surface of the front bottom roller is rough, and the surface of the rear bottom roller is relatively smooth. They are connected to the motor through the reduction gear box. The platen roller, also called the load roller, acts to create a downward pressure whose pressure is the difference between its own weight and the load roller lifting pressure. The unwinding roller is composed of a leg paper holder, a unwinding roller coupling, a unwinding roller clamping mechanism, and a unwinding motor. Longitudinal cutters generally have book holders side by side on the same axis, mainly used to cut off the change. Cut a certain width of sheet paper to the required width as needed. Two tension sensors are placed on the tension roller to receive the web tension.

Belt rewinding machine design and working principle ---

8 core filling
The core loading device supplies a paper core between the take-up rolls.
Construction
A fork-like paper core loader is mounted on the paper feed roller. The core loader includes a paper core clip and a centering tray. The core loader is hydraulically operated. The movement of the paper core clamp is operated by compressed air.
working principle 
The core is placed on a tray in the core loader. It is fixed in position by the paper core clamp.
During the rewinding process, the core loader opens and the new core is advanced. When the core loader is full, the paper core clamp will run to grip the paper core. The core loader moves to the position it should wait when the paper feed roller moves. When the paper advance roller reaches the position where the paper roll is ejected, the core loader is lowered to the drop position. The core holder is opened and the core falls into the middle of the roll.
