PURPOSE: An opening and closing type screen sheet system is provided to easily replace a screen sheet and to reduce working hours for replacing the screen sheet. CONSTITUTION: An opening and closing type screen sheet system(100) includes a support(102), a screen box(104), an actuating motor, a winding drum, a guide rail, a first screen sheet(112), a second screen sheet(114), a first integrated fixture(116), a third screen sheet(118), and a second integrated fixture(120). The supports are installed at regular intervals. The screen boxes are installed between the upper side surfaces of the supports. The actuating motor is installed at one side of the screen box, and rotates forward and backward depending on the control signal of a controller. The winding drum is connected to the actuating motor, and is rotated by the forward and backward rotation of the actuating motor. The guide rails are vertically formed on the centers of the supports. The first screen sheet is inserted into between the guide rails, and can slide. The first screen sheet is connected to the winding drum, and slides up and down depending on the rotation of the winding drum in order to open or close an entrance. The second screen sheet is inserted into between the guide rails, and can slide. The first integrated fixture is installed in between the first screen sheet and the second screen sheet, and slides the second screen sheet up and down in order to open or close the entrance when the first screen sheet slides. The third screen sheet is inserted into between the guide rails, and can slide. The second integrated fixture is installed in between the second screen sheet and the third screen sheet, and slides the third screen sheet up and down in order to open or close the entrance when the second screen sheet slides. |
