The size of curtain is determined according to the size of crossbeam and cantilever, and base fabric is woven into using glass thread, and surface layer is coated with PVC
Material is processed into curtain, and the top side of the curtain after processing is fixed with the reel in cantilever, and curtain is made to keep water
It is flat, the bottom side of curtain is passed through into through slot after the first locating wheel, is fixedly connected through the second locating wheel with crossbeam, protected
Card curtain is disposed vertically rear corrugationless, pulls downward on crossbeam, then unclamps arm, drives reel rotation by torsionspring,
And then curtain and crossbeam is driven to move up, the situation of movement of curtain and crossbeam is observed, until curtain and crossbeam steadily move；
4) link mechanism is installed
A, the upper locating piece and lower locating piece to match with cantilever and crossbeam is selected first, and upper locating piece is limited by the first fixture block
Position is fixed in the first groove with the first lock-screw, and lower locating piece is limited in the second groove by the second fixture block,
It is fixed with the second lock-screw；
B, the then fixed link on right angle setting on the bottom surface of upper locating piece, and limit is uniformly opened up on the side of upper fixed link
Hole, the fixed link under right angle setting on the top surface of lower locating piece, and telescopic rod is installed on the top of lower fixed link, on telescopic rod
Uniformly installation elastic limit block；
C, then the top of telescopic rod is inserted into upper fixed link, moving beam makes curtain reach the length of setting, then will be corresponding
Elastic limit block be caught in and realize in limit hole and fix；
5) large-size screen monitors laser projection device is tested
Large-size screen monitors laser projection device is fixed on the wall according to the requirement in place first, curtain is then determined according to the size in place
The extension elongation of cloth by pulling downward on crossbeam to setting position, and is fixed by elastic limit block and limit hole, reaches curtain
To the length of needs, then cable and Intelligent platform are attached, projected picture on curtain by projector, when in intelligence
When corresponding position is write on energy dais, it is transferred on the projecting lamp of rotating cylinder by electric signal, corresponding text is projected
To the corresponding position of curtain, while controller can be worked by speed sensorless control servo motor, and then pass through driving tooth
Wheel and driven gear control rotating cylinder rotation, rotate projecting lamp, and then the font controlled on curtain moves down.
