Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass tempering equipment, in particular to a curved air grille air outlet structure. Background Art
[0002] In the prior art, after the softened glass is bent into shape by a forming device, a bending wind grid is required to output cooling air to quickly cool the formed glass so as to temper the bent glass.
[0003] Multiple wind grid bars connected to the upper bending mechanism and the lower bending mechanism form two curved surfaces that are bent toward the glass to be tempered and have the same curvature, one of which protrudes toward the glass to be tempered and the other is a concave curved surface; multiple blowing boxes are installed on the side of each wind grid bar facing the glass to be tempered, and multiple air outlet holes are arranged on the side of the blowing box facing the glass to be tempered, and cooling air is output to the surface of the glass to be tempered through the air outlet holes.
[0004] Since the box body of the blowing box in the prior art is a rectangular parallelepiped, when multiple wind grid bars form a curved surface protruding toward the glass to be tempered, the two ends of the two blowing boxes located on two adjacent wind grid bars and opposite to each other are close to each other. As the radial depth of the curved surface increases, the two ends of the two relatively close blowing boxes will offset each other, thereby causing interference and hindering the upper bending mechanism or the lower bending mechanism from continuing to drive the multiple wind grid bars to bend to reach the required radial depth, so that the curved depth of the glass to be tempered that can be prepared is limited and cannot meet customer needs.

[0028] A curved wind grille air outlet structure, comprising an upper curved wind grille and a lower curved wind grille, each of the upper curved wind grille and the lower curved wind grille comprising a plurality of wind grille bars 1 and a plurality of blowing boxes 2; the wind grille bars 1 extending along the direction in which the glass is moved; the plurality of wind grille bars 1 located on the upper curved wind grille or the lower curved wind grille are arranged adjacent to each other in sequence and are respectively connected to an upper bending arc mechanism or a lower bending arc mechanism; the plurality of blowing boxes 2 are respectively connected to a side of the wind grille bar 1 facing the glass to be tempered, and a plurality of air outlet holes are arranged on a side of the blowing box 2 facing the glass to be tempered; the blowing box 2 extends in a direction perpendicular to the length direction of the wind grille bar 1;
[0029] The ends of the blowing box 2 are exposed on both sides of the wind grid bar 1, and the end surfaces of both ends of the blowing box 2 are inclined surfaces 22; the side of the inclined surface 22 close to the wind grid bar 1 is a straight edge 222, and the other side of the inclined surface 22 away from the wind grid bar 1 is an arcuate edge 221;
[0030] The distance between the two straight edges 222 of the same blowing box 2 is smaller than the distance between the two arcuate edges 221 .
[0031] like Figure 1 and Figure 2 The structure diagram of the curved wind grille air outlet structure of the present invention is shown.
[0032] During operation, the upper bending mechanism or the lower bending mechanism drives the multiple connected wind grid bars 1 to form a curved surface protruding toward the glass to be tempered, that is, the upper bending mechanism bends downward to form a curved surface protruding toward the glass to be tempered, so that the tempered glass is a downwardly concave curved steel glass; or the lower bending mechanism bends upward to form a curved surface protruding toward the glass to be tempered, so that the tempered glass is an upwardly protruding curved steel glass, which will make the two ends of the two opposite blowing boxes 2 located on the two adjacent wind grid bars 1 close to each other, and the end faces of both ends of the blowing box 2 are both set with inclined surfaces 22, and the distance between the two straight edges 222 of the same blowing box 2 is smaller than the distance between the two arc-shaped edges 221, which can avoid the sides of the two opposite blowing boxes 2 away from the glass to be tempered from abutting against each other and interfering with each other, and can avoid the phenomenon that the curved surface formed due to the interference of the two blowing boxes 2 does not reach the required radial depth.
[0033] Preferably, along the central axis of the wind grid bar 1, the plurality of blowing boxes 2 are staggered and distributed.
[0034] like Figure 1 As shown, the multiple blowing boxes 2 are staggered relative to the central axis of the wind grid bar 1, so that the gaps between two adjacent and close blowing boxes 2 are staggered, so that the end faces of the multiple blowing boxes 2 exposed to the same wind grid bar 1 are not in the same plane parallel to the central axis of the wind grid bar 1, which can avoid the phenomenon that the corresponding parts of the glass are not blown by cooling air during the tempering process, thereby avoiding affecting the tempering quality of the glass.
[0035] Preferably, the side of the blowing box 2 facing the glass to be tempered is a curved surface 21;
[0036] The plurality of air outlet holes are staggered and distributed on the arc surface 21 .
[0037] like Figure 2 As shown, a plurality of air outlet holes are staggered and distributed on the arc surface 21 of the blowing box 2 facing the glass to be tempered, which can improve the uniformity of the distribution of the cooling air on the surface of the glass to be tempered.
[0038] Specifically, the arc surface 21 includes a plurality of long strip planes 211, and the long strip planes 211 extend along the length direction of the blow box 2. The long sides of the plurality of long strip planes 211 are sequentially connected, so that the arc surface 21 forms a multi-faceted surface.
[0039] The plurality of elongated planes 211 are distributed symmetrically with respect to a plane perpendicular to the central axis of the wind grid bar 1 and where the central axis of the blowing box 2 is located;
[0040] Along a direction perpendicular to the central axis of the blow box 2 , angles between the plurality of long strip planes 211 sequentially arranged outward from the center point of the blow box 2 and the horizontal plane where the central axis of the blow box 2 is located increase sequentially.
[0041] like Figure 2 As shown, the arc surface 21 including a plurality of long strip planes 211 forms a multi-faceted surface, and the angles between the plurality of long strip planes 211 arranged sequentially from the center point of the blowing box 2 to the outside and the horizontal plane where the central axis of the blowing box 2 is located increase sequentially, so that the blowing area of the cooling air distributed on the surface of the glass to be tempered is expanded, which can avoid the phenomenon that the surface part of the glass to be tempered between two adjacent blowing boxes 2 located on the same wind grid 1 is not covered by cooling air.
[0042] In addition, the arrangement of the arcuate surface 21 including a plurality of elongated flat surfaces 211 can also improve the convenience of positioning operations when drilling holes in the elongated flat surfaces 211 .
[0043] Furthermore, the wind grid bar 1 is connected to the output ends of multiple air supply pipes, and the wind grid bar 1 is provided with multiple cold air outlets. The blowing box 2 is connected to the wind grid bar 1 through the corresponding cold air outlets, and the cold air outlets are located in the middle of the contact surface between the blowing box 2 and the wind grid bar 1;
[0044] The plurality of air outlet holes are divided into a first air outlet hole 2112 and a second air outlet hole 2111;
[0045] The aperture of the first air outlet 2112 is smaller than the aperture of the second air outlet 2111;
[0046] A plurality of the first air outlet holes 2112 are arranged on the long strip plane 211 close to the cold air outlet;
[0047] A plurality of second air outlet holes 2111 are arranged on the long strip plane 211 away from the cold air outlet, and the second air outlet holes 2111 are located on a side of the first air outlet hole 2112 away from the central axis of the blower box 2 .
[0048] like Figure 2 As shown, the first air outlet 2112 is close to the cold air output port, and the aperture of the first air outlet 2112 is set to be smaller than the aperture of the second air outlet 2111, so that the flow rate of the cooling air output from the first air outlet 2112 is relatively larger, which can increase the flow rate of the cooling air output from the first air outlet 2112, thereby improving the cooling effect of the cooling air on the surface of the tempered glass and improving the quality of glass tempering.
[0049] In summary, if Figure 1-2 In the embodiment of the utility model shown, the curved wind grid air outlet structure has end faces of both ends of the blowing box 2 that are inclined surfaces 22, and the distance between the two straight edges 222 of the same blowing box 2 is smaller than the distance between the two curved edges 221, which can avoid the two ends of the two relatively close blowing boxes 2 from resisting and interfering with each other, thereby increasing the adjustable range of the bending depth of the tempered glass obtained.
