The curtain surface unit 201 is a rectangular plate-shaped structure, and the top and the bottom of the curtain surface unit 201 are respectively provided with a hinge shaft 2011 and a connecting plate 2012 corresponding to the hinge shaft 2011; the adjacent curtain surface units 201 are connected through the hinge joint of the connecting plate 2012 and the hinge shaft 2011; the top and the bottom of one side of the curtain surface unit 201 facing the scroll 101 are respectively provided with a fillet 2013; the through groove 202 is arranged on the other side of the curtain surface unit 201 opposite to the round angle 2013.
The side surface of the curtain surface unit 201 is provided with a plurality of uniformly distributed air holes 203, and the air holes 203 are communicated to the penetrating grooves 202.
The inner side of the bottom of the through groove 202 is hinged with a baffle 204, and the free end of the baffle 204 is supported by a limit plate 205 arranged at the bottom of the through groove 202.
A partition plate 104 is arranged in the box 1, the partition plate 104 partitions the reel 101, a relatively closed air draft air box 105 is formed in the box 1, and an air draft fan 103 is arranged on the wall of the air draft air box 105; an inlet 106 for the curtain surface 2 to enter is arranged on the clapboard 104, and an outlet 107 for the curtain surface 2 to pass through is arranged at the bottom of the air draft bellows 105; the curtain 2 on the roller 101 extends outside the box 1 through an inlet 106 in the partition 104 and an outlet 107 in the bottom of the suction box 105.
The partition plate 104 is of an inverted L-shaped structure, the scroll 101 is divided at the left lower corner of the box 1 by the partition plate 104, and the rest part is an air draft bellows 105; the exhaust fan 103 is arranged at the top of the box 1; the outlet 107 is provided at the right side of the bottom of the box 1 at a position corresponding to the suction bellows 105, and the inlet 106 is provided at the bottom of the partition 104 at a position near the outlet 107.
Further, the bottom of the partition board 104 is further provided with an inward bending part 108, and the inclination angle of the bending part 108 is 45 degrees; the inlet 106 is provided on the bend 108.
Further, the inlet 106 includes two arc-shaped support plates 1061 disposed oppositely, the bending portion 108 is provided with a notch portion 1081, the arc-shaped support plates 1061 are disposed on the partition plates 104 at two sides of the notch portion 1081, respectively, and a gap is left between the arc-shaped support plates 1061; the arc-shaped support plates 1061 are respectively provided with arc-shaped sliding plates 1062, and the backs of the sliding plates 1062 slide in the arc-shaped support plates 1061; the front part of the sliding plate 1062 is respectively provided with two symmetrical roll shafts 1063; when the curtain surface 2 passes through the inlet 106, two sides of the curtain surface are respectively supported on the corresponding roller 1063 of the sliding plate 1062.
When the device is used, the rolling door machine drives the scroll to control the rolling and releasing of the curtain surface.
When the curtain face is discharged, the curtain face firstly passes through the inlet on the partition plate, and is discharged to the outside of the box through the outlet at the bottom of the box, the position of the curtain face is limited by the inlet, and the inlet is required to be arranged on the partition plate because the relative air tightness in the air draft bellows is required to be ensured.
