[0034] Referring to Figure 1 and Figure 2 , Figure 1 The schematic view of a glass toughening cooling air grid provided by an embodiment of the present application is shown in the figure, wherein a blowing piece is arranged on the air grid strip of the glass toughening cooling air grid. Figure 2The embodiment of the present application provides a schematic view of a glass toughening cooling air grid provided with two air blowing parts on the air grid strip. The glass toughening cooling air grid provided by the embodiment of the present application comprises at least one air blowing group 10, the air blowing group 10 comprises at least two air grid strips 100 arranged along the running direction of the glass 20; each air grid strip 100 comprises at least one air blowing part 110, each air blowing part 110 comprises a plurality of air outlets 111 uniformly arranged along a first direction; when the number of the air blowing parts 110 comprised by the air grid strip 100 is greater than or equal to two, the air blowing parts 110 of the same air grid strip 100 are sequentially arranged along the running direction of the glass 20; among the air blowing parts 110 of the adjacent air grid strips 100, two air blowing parts 110 located at the same position along the running direction of the glass 20 are defined as a corresponding group; among the two air blowing parts 110 comprised by each corresponding group, two first air outlets 111 located at the same side are relatively staggered along the first direction, and the first direction is perpendicular to the running direction of the glass 20.

[0035] The glass toughening cooling air grid in the present application is applied to an air grid device. The air grid device further comprises a conveying roller, and the conveying roller is provided with the glass toughening cooling air grid on both sides in the radial direction. The conveying roller is used for driving the glass 20 to move along the running direction, so that the gas blown out through the air outlets 111 can act on the glass 20 to cool the glass 20.

[0036] Specifically, in the present application, among the air blowing parts 110 of the adjacent air grid strips 100, two air blowing parts 110 located at the same position along the running direction of the glass 20 are defined as a corresponding group, among the two air blowing parts 110 comprised by each corresponding group, two first air outlets 111 located at the same side are relatively staggered along the first direction, since each air blowing part 110 comprises a plurality of air outlets 111 uniformly arranged along the first direction, the air outlets 111 in each corresponding group are relatively staggered as a whole, so that the arrangement of the air outlets 111 of each air blowing group 10 is more uniform, the air blowing range and the air blowing uniformity are increased, and thus the cooling effect on the glass 20 is better, the wind spots can be reduced, and the quality of the toughened glass 20 is improved. The first direction is the extension direction of the air grid strip 100.

[0037] It should be noted that due to the size limitation of the air grid strip 100 in the first direction, the air outlets 111 in some air blowing parts 110 may be incomplete in the staggered position, or the air outlets 111 can be additionally arranged in some areas of the air grid strip 100, therefore, the number of the air outlets 111 in each air blowing part 110 can be different, and a plurality of air outlets 111 in each air blowing part 110 are uniformly arranged along the first direction, therefore, in the embodiment, the positions of the two first air outlets 111 located at the same side in the two air blowing parts 110 comprised by each corresponding group are compared and contrasted, and the other air outlets 111 in the same air blowing part 110 can be correspondingly arranged.

[0038] See Figure 1 and Figure 2 In one embodiment, the blower group 10 includes N wind grid strips 100 arranged along the travel direction of the glass 20. In each corresponding group, among the two blower elements 110, the first air outlet 111 at one end of the blower element 110 located upstream of the travel direction of the glass 20 is offset from the first air outlet 111 on the same side of the blower element 110 located downstream of the travel direction of the glass 20 by a third preset distance. The third preset distance is 1 / N times the distance between the center points of adjacent air outlets 111 in any blower element 110, where N is an integer greater than zero.

[0039] Specifically, the blowing group 10 includes N air gratings 100 arranged along the traveling direction of the glass 20. The third preset distance is 1 / N times the distance between the center points of adjacent air outlets 111 in any blowing element 110. This allows the air outlets 111 in each blowing element 110 on the N air gratings 100 in each blowing group 10 to cover the air gratings 100 in the first direction, forming a seamless full-coverage connection for blowing. This ensures uniform blowing on the upper and lower surfaces of the glass 20. At the same time, in the traveling direction of the glass 20, the air outlets 111 located at the same position on each air grating 100 are staggered, further improving the uniformity of the arrangement of each air outlet 111 and increasing the blowing range and uniformity.

[0040] It should be noted that in this embodiment, the value of N is 4, that is, the third preset distance is 1 / 4 times the distance between the center points of adjacent air outlets 111 within any blower 110. In other embodiments, N can also be other values.

[0041] Among them, the instruction manual is attached Figure 1 Taking an example, four air grates 100 form a blower group 10. In the blower group 10 at the head end, in the direction from left to right, the first air outlet 111 on the upper side of each air grate 100 is offset upwards from the first air outlet 111 on the left side of the adjacent air outlet 111 by 1 / 4 times the distance between the center points of adjacent air outlets 111 in any blower 110.

[0042] See Figure 1 In one embodiment, each air grating 100 is provided with an air blowing element 110, and the aperture d of each first air outlet 111 is equal. The distance between the center points of adjacent first air outlets 111 in any air blowing element 110 is 2.5 to 3.5 times the aperture d.

[0043] Specifically, in order to cope with different sizes of glass 20, different types of toughening furnaces are provided, and when each air baffle 100 is provided with one blowing piece 110, it is used to adapt to the corresponding type of toughening furnace. Wherein, when each air baffle 100 is provided with one blowing piece 110, the aperture d of each first air outlet 111 is larger, so as to reduce the air temperature and improve the cold zone effect on the glass 20.

[0044] Referring to Figure 2 and Figure 3 , Figure 3 The schematic view of the glass toughening cooling air baffle provided by an embodiment of the present application is provided with three blowing pieces on the air baffle. In one embodiment, each air baffle 100 is provided with at least two blowing pieces 110 arranged along the direction of glass 20 movement, and in any adjacent blowing pieces 110 on any air baffle 100, the first air outlet 111 located at one end of the blowing piece 110 on the upstream side of the glass 20 movement direction is staggered along the first direction with the first air outlet 111 located on the same side of the blowing piece 110 on the downstream side of the glass 20 movement direction, so that the arrangement of each air outlet 111 on each air baffle 100 is more uniform, further increasing the blowing range and blowing uniformity of each air baffle 100, so that the stress distribution of the glass 20 after toughening is more uniform, and a better wind spot improvement effect is achieved.

[0045] Referring to Figure 2 , in one embodiment, the air baffle 100 is provided with two blowing pieces 110, and in any adjacent blowing pieces 110 on any air baffle 100, the first air outlet 111 located at one end of the blowing piece 110 on the upstream side of the glass 20 movement direction is staggered along the same direction with the first air outlet 111 located on the same side of the blowing piece 110 on the downstream side of the glass 20 movement direction by a first preset distance, and the first preset distance is 1 / 2 times the distance between the center points of adjacent air outlets 111 in any blowing piece 110, so that each air outlet 111 in the two blowing pieces 110 on each air baffle 100 can be uniformly arranged along the direction of glass 20 movement, so that each air outlet 111 is uniformly staggered, so that the blowing is more uniform, and the corresponding blowing range of each air baffle 100 is wider. And since the third preset distance is 1 / 4 times the distance between the center points of adjacent air outlets 111 in any blowing piece 110, the air outlets 111 on each air baffle 100 are staggered in the direction of glass 20 movement, further improving the uniformity of the arrangement of each air outlet 111 and increasing the blowing range and blowing uniformity.

[0046] Among them, the drawings in the specification Figure 2For example, in the left-to-right direction, on the first end of the air baffle strip 100, the outlet 111 of the lower side of the two air blowing parts 110, the first outlet 111 on the right side is staggered upward by 1 / 2 of the distance between the center points of the adjacent outlets 111 in any air blowing part 110.

[0047] Referring to Figure 2 In one embodiment, when two air blowing parts 110 are provided on the air baffle strip 100, the apertures d of the outlets 111 are equal, and the distance between the center points of the adjacent outlets 111 in any air blowing part 110 is 4.5-6.5 times the aperture d.

[0048] Specifically, to cope with different sizes of glass 20, different types of tempering furnaces are provided, and when two air blowing parts 110 are provided on each air baffle strip 100, the air baffle strip 100 is adapted to the corresponding type of tempering furnace. When two air blowing parts 110 are provided on each air baffle strip 100, the apertures d of the outlets 111 are equal and larger to reduce the air temperature and improve the cold zone effect on the glass 20. It should be noted that when the number of air blowing parts 110 provided on the air baffle strip 100 is different, the apertures d of the outlets 111 are not equal.

[0049] Referring to Figure 3 In one embodiment, three air blowing parts 110 are provided on the air baffle strip 100, and an auxiliary part 120 is also provided on the air baffle strip 100. The auxiliary part 120 includes a plurality of air blowing outlets 121 uniformly spaced in the first direction. In the first direction, the auxiliary part 120 coincides with the air blowing part 110 located in the middle position, and each air blowing outlet 121 is staggered with the outlet 111 located in the middle position.

[0050] Specifically, three air blowing parts 110 are provided on the air baffle strip 100, and the air blowing part 110 located in the middle position has poor heat dissipation effect compared to the air blowing parts 110 located on both sides, so that the cooling effect of the cooling air blown by the air blowing part 110 located in the middle position on the glass 20 is weaker than the cooling effect of the glass 20 by the air blowing part 110 located in the middle. By coinciding the auxiliary part 120 with the air blowing part 110 located in the middle position in the first direction, and staggering each air blowing outlet 121 with the outlet 111 located in the middle, the outlets 111 and air blowing outlets 121 in the middle of each air baffle strip 100 can blow more cooling air, thereby improving the air blowing effect of the air baffle strip 100 on the glass 20 in the middle position and improving the uniformity of the air blowing on the surface of the glass 20.

[0051] In one embodiment, in the air blowing part 110 located in the middle position, the distance between the center points of the two adjacent outlets 111 and the air blowing outlet 121 located therebetween is equal.

[0052] Specifically, on the blowing part 110 located in the middle position, each blowing port 121 is arranged at the middle position between two adjacent air outlets 111, so that the air outlets 111 located in the middle position and the blowing ports 121 are uniformly arranged, and the uniformity of blowing glass 20 is improved. Preferably, the size and shape of the blowing port 121 and the air outlet 111 are the same.

[0053] Referring to Figure 3 In one embodiment, on any air grid strip 100, the first air outlet 111 located at one end of the blowing part 110 on the upstream side of the glass 20 running direction is offset by a second preset distance in the same direction as the first air outlet 111 located on the same side of the blowing part 110 on the downstream side of the glass 20 running direction, and the second preset distance is 1 / 4 of the distance between the center points of adjacent air outlets 111 in any blowing part 110, so that the air outlets 111 on each air grid strip 100 can be uniformly arranged in the first direction, and the air outlets 111 and the blowing ports 121 are uniformly offset, so that the glass 20 is blown more uniformly, and the blowing range of each air grid strip 100 is wider.

[0054] In the drawings, Figure 3 For example, in the direction from left to right, on the first air grid strip 100, the first air outlet 111 on the right side of the upper blowing part 110 is offset upward by 1 / 4 of the distance between the center points of adjacent air outlets 111 in any blowing part 110 relative to the first air outlet 111 on the left side.

[0055] Referring to Figure 3 In one embodiment, three blowing parts 110 are provided on the air grid strip 100, the apertures d of the air outlets 111 are equal, and the distance between the center points of adjacent air outlets 111 in any blowing part 110 is 6-8 times the aperture d.

[0056] Specifically, different sizes of glass 20 have different types of tempering furnaces, and when three blowing parts 110 are provided on each air grid strip 100, they are used to adapt to the corresponding type of tempering furnace. When three blowing parts 110 are provided on each air grid strip 100, the apertures d of the air outlets 111 are equal, which can reduce the air temperature and improve the cold zone effect on the glass 20 compared with the prior art in which the outer air outlet is small and the middle air outlet is large.

[0057] Referring to Figure 4 and Figure 5 , Figure 4 The first schematic view of the glass tempering cooling air grid provided by an embodiment of the present application shows that four blowing parts are provided on the air grid strip. Figure 5A second schematic view of the glass tempering cooling air grid provided by an embodiment of the present application is shown in FIG. 2, in which four air blowing members are arranged on the air grid strip. In one embodiment, four air blowing members 110 are arranged on the air grid strip 100, and the distance between the center points of the adjacent air outlets 111 in each air blowing member 110 is L. In any air grid strip 100, in the first direction, the first air outlet 111 at one end of the three air blowing members 110 is staggered by L / 4, L / 2 and 3L / 4, respectively, with the first air outlet 111 at the same side of the other air blowing member 110.

[0058] Specifically, the four air blowing members are defined as a first air blowing part 112, a second air blowing part 113, a third air blowing part 114 and a fourth air blowing part 115, in which the air outlet 111 in the second air blowing part 113 is staggered by L / 4 with the corresponding air outlet 111 in the first air blowing part 112, the air outlet 111 in the third air blowing part 114 is staggered by L / 2 with the corresponding air outlet 111 in the first air blowing part 112, and the air outlet 111 in the fourth air blowing part 115 is staggered by 3L / 4 with the corresponding air outlet 111 in the first air blowing part 112. By arranging the first air blowing part 112, the second air blowing part 113, the third air blowing part 114 and the fourth air blowing part 115 on each air grid strip 100, the air outlets 111 on each air grid strip 100 can be uniformly arranged in the first direction, and the air outlets 111 are uniformly staggered, so that the air blowing on the glass 20 is more uniform, and the corresponding air blowing range of each air grid strip 100 is wider. In the direction along the movement direction of the glass 20, the first air blowing part 112, the second air blowing part 113, the third air blowing part 114 and the fourth air blowing part 115 can be arranged in any order on each air grid strip 100.

[0059] In one embodiment, the first air blowing part 112, the second air blowing part 113, the third air blowing part 114 and the fourth air blowing part 115 are arranged on the air grid strip 100 in the order of the first air blowing part 112, the second air blowing part 113, the third air blowing part 114 and the fourth air blowing part 115 from left to right, and in the direction along the movement direction of the glass 20. Figure 4 For example, in the direction along the movement direction of the glass 20, the first air blowing part 112, the fourth air blowing part 115, the second air blowing part 113 and the third air blowing part 114 can be arranged in the order of the first air blowing part 112, the fourth air blowing part 115, the second air blowing part 113 and the third air blowing part 114, and in the direction from left to right, the air outlet 111 at the lower side of the four air blowing members 110 on the air grid strip 100 at the first end is staggered by 3L / 4, L / 4 and L / 2, respectively, upward with respect to the adjacent air outlet 111 at the left side.

[0060] In another embodiment, the first air blowing part 112, the second air blowing part 113, the third air blowing part 114 and the fourth air blowing part 115 are arranged on the air grid strip 100 in the order of the first air blowing part 112, the second air blowing part 113, the third air blowing part 114 and the fourth air blowing part 115 from left to right, and in the direction along the movement direction of the glass 20. Figure 5Taking this example, along the direction of travel of the glass 20, the arrangement order can be the first air outlet 112, the third air outlet 114, the second air outlet 113 and the fourth air outlet 115. In the direction from left to right, on the wind grid strip 100 at the beginning, the air outlet 111 located on the lower side of the four blowing elements 110, the first air outlet 111 on the right side is offset upward by L / 2, L / 4 and 3L / 4 respectively relative to the first air outlet 111 on the adjacent left side.

[0061] In other embodiments, the order of the first air outlet 112, the third air outlet 114, the second air outlet 113 and the fourth air outlet 115 along the travel direction of the glass 20 can be different, and will not be described in detail here.

[0062] See Figure 4 and Figure 5 In one embodiment, the air grating 100 is provided with four air blowing elements 110. In each air blowing element 110, the diameter d of each air outlet 111 is equal, and the distance between the center points of adjacent air outlets 111 is 7.5 to 9.5 times the radius d.

[0063] Specifically, to accommodate different sizes of glass 20 and different models of tempering furnaces, when each air grille 100 is equipped with four air blowing elements 110, it is used to adapt to the corresponding model of tempering furnace. When each air grille 100 is equipped with four air blowing elements 110, the diameter d of each air outlet 111 is equal. Compared to the existing technology where the outer air outlet is smaller and the middle air outlet is larger, this can reduce the air temperature and improve the cooling effect on the glass 20.

[0064] In other embodiments, to accommodate glass 20 of different sizes and tempering furnaces of different models, each air grid bar 100 may also be provided with five air blowing elements 110, six air blowing elements 110, etc.

[0065] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In one embodiment, in the adjacent groups of blowing groups 10, the arrangement order of each blowing element 110 in the blowing group 10 located upstream of the glass 20 in the direction of travel is the opposite of the arrangement order of each blowing element 110 in the blowing group 10 located downstream of the glass 20 in the direction of travel. That is, by alternately blowing air to various positions on the glass 20 through each air outlet 111 in each group of blowing groups 10, the uniformity of blowing air on the surface of the glass 20 is further increased.

[0066] See Figure 1 , Figure 2 , Figure 3 and Figure 4The embodiment of the present application further provides a wind grid device, comprising the glass toughening cooling wind grid, and further comprising a conveying roller way, and the conveying roller way is provided with the glass toughening cooling wind grid on both sides in the radial direction, and the conveying roller way is used for driving the glass 20 to move along the advancing direction.

[0067] Specifically, in the present application, two blowing parts 110 located at the same position along the advancing direction of the glass 20 in adjacent wind grid strips 100 are defined as a corresponding group, and the two first air outlets 111 located at the same side in the two blowing parts 110 in each corresponding group are relatively staggered in the first direction, and since each blowing part 110 comprises a plurality of air outlets 111 uniformly and spaced apart in the first direction, each air outlet 111 in the two blowing parts 110 in each corresponding group is relatively staggered as a whole, so that the arrangement of each air outlet 111 in each wind grid strip 10 is more uniform, the blowing range and the blowing uniformity are increased, and thus the cooling effect on the glass 20 is better, the wind spot can be reduced, and the adaptability of the wind grid device is improved.

[0068] The technical features of the above-described embodiments can be combined in any manner, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0069] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
