[0002] Existing air curtain shell panels usually use a single curved panel or straight folded edge made of metal thin plates as the front panel of the air curtain, which is covered on the front of the air curtain frame, so as to protect the internal parts However, due to the fact that the front panel or straight edge of the single-curved air curtain machine made of integrated metal sheets often has a large plane area and a long span, the width:length ratio of the front is 1:4~7 Among them, to make the front panel really achieve the protective effect, it is often necessary to achieve sufficient protection strength by thickening the thickness of the metal sheet material. In addition, the single curved shape of the single-curved air curtain panel and the straight-line folded line of the straight plate do not match the involute shape required by the air collection function of the air curtain shell, which affects the The effective wind speed of the air curtain machine and these shortcomings need to be improved

Embodiment Construction
[0007] Below with embodiment and accompanying drawing, the present invention is described in further detail:
[0008] refer to figure 1 and figure 2 , the present invention includes an air curtain machine front panel 1 made of metal thin plates integrated, on the front panel 1 along the radial direction of the wind wheel 5, integrally formed S-shaped hyperboloids 2, 3 are rolled, and the S-shaped hyperboloids 2 and 3 are composed of a smooth transition between the upper curved surface 2 and the lower curved surface 3. The R circle center 4 of the upper curved surface 2 and the R circle center 6 of the lower curved surface 3 are respectively located on the inside and outside of the front panel 1 of the air curtain machine. direction. Since the S-shaped hyperboloids 2 and 3 are rolled radially along the wind wheel 4 on the front panel 1, it is equivalent to rolling two corrugated ribs along the horizontal direction, thus greatly strengthening the front panel made of the metal...

The invention relates to a panel of a wind curtain machine. On a front panel of the wind curtain machine prepared by a whole metal sheet, an S-shaped hyperboloid is prepared by a rolling way, which is equal to adding two rolled corrugated reinforcement ribs on the front panel along the horizontal direction, thereby greatly increasing integrative rigidity and intensity of the front panel prepared by the metal sheet, reaching the purposes of saving material cost and enhancing protection; on the front panel, the S-shaped hyperboloid is rolled along the radial of a wind wheel, which replaces an expanding type shape and an plate-edge-folded type shape of a single-curved surface of the front panel of a traditional wind curtain machine, better meets requirements of the opposite wind wheel of the external shell of the wind curtain machine on the involute-typed wind-drive function, can effectively improve wind speed and is applicable to various wind curtain machines.
