What is the division of the internal components of the mask folding and packing machine during work?
1. Tension test roller This roller is the main component that controls the tension when the film of the mask folding and packing machine is rewinded. Usually the tension of the film is detected by the pressure sensor under the bearing at both ends of the tension roller. The detected signal passes through the electronic circuit and controls the mask folding and packaging machine. Winding the motor speed to ensure proper winding tension.
2. The flattening roll flattens the film and eliminates some longitudinal wrinkles produced by the film under tensile stress.
3. The tracking roller is equipped with a tracking roller (also called a pinch roller) which can be changed in position in front of the core of the mask folding and packaging machine. Its main function is to press the film against the winding core to perform contact winding or small clearance. Rewinding is done so that the flat film can be quickly transferred to the core to achieve flat rolling. At the same time, a certain pressure is applied to the mother roll by means of the tracking roller, and the air between the film layers is removed in a timely manner so that the mother roll does not become loose. The air content in the mother roll after the general use of the tracking roller can be reduced to 12% to 18%.
4。 The winding roller is driven by the winding motor of the mask folding and packaging machine。 The control system of the winding speed is linked with the driving system of the stretching machine and synchronized with the stretching machine, and is controlled by the feedback control of the tension controller。
5. The turntable and the empty core do not allow the mask folding and packing machine to stop and replace the core when the film is full of a mandrel. Therefore, the turntable is turned back 180°, the mother roll turns away, the empty winding core enters the winding position, and then the film is cut off. Place the film on the new core and continue winding.
