[0033] It should be noted that the embodiments in the present application and the features involved in the embodiments can be combined with each other without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0034] Embodiment one
[0035] As shown in the accompanying drawings, a tempering equipment for improving glass tempering quality comprises a conveying roller 2, an air pressing plate 6, an upper wind grid group 3 and a lower wind grid group 4. Figures 1-4
[0036] The conveying roller 2 is used for supporting and conveying the hot glass 1 along a specific direction.
[0037] The upper wind grid group 3 and the lower wind grid group 4 are respectively composed of a plurality of wind grid bodies 5 which are parallel to each other and arranged at intervals, and the wind grid bodies 5 in the upper wind grid group 3 and the lower wind grid group 4 are arranged along the transmission direction of the conveying roller 2.
[0038] The conveying roller 2 is arranged between the air gate bodies 5 of the lower air gate group 4, and the hot glass 1 is located on the conveying roller 2. During the movement of the hot glass 1 on the conveying roller 2, the air gate bodies 5 in the upper air gate group 3 blow air towards the lower side to cool the hot glass 1, and the air gate bodies 5 in the lower air gate group 4 blow air towards the upper side to cool the hot glass 1.
[0039] The air gate body 5 is in the form of a long strip-shaped profile structure, and the material thereof can be selected as an aluminum alloy. The air gate body 5 in the utility model is provided with two air blowing gaps 51.
[0040] The air blowing gap 51 is a long strip-shaped gap formed in the air gate body 5, and the length direction thereof is the same as the length direction of the air gate body 5. The two air blowing gaps 51 on the same air gate body 5 are completely the same in size and shape. After the cold air enters the air gate body 5, the cold air passes through the two air blowing gaps 51 to blow towards the hot glass 1.
[0041] In other embodiments, each air blowing gap 51 can also be composed of a plurality of short gaps arranged at intervals. The short gaps in the two air blowing gaps 51 on the same air gate body 5 are staggered, so that the effect of fully covering the surface of the glass can be achieved.
[0042] The air pressing plate 6 is horizontally arranged between any two adjacent air gate bodies 5 in the upper air gate group 3. Optionally, the two ends of the air pressing plate 6 are inclined and downwardly deviated to the two sides, respectively.
[0043] In the embodiment, the two ends of all the air gate bodies 5 in the lower air gate group 4 are provided with the air blocking structure 7. The air blocking structure 7 is arranged to extend towards the hot glass 1, so that the distance between the side of the air blocking structure 7 close to the hot glass 1 and the hot glass 1 is less than the distance between the air blowing face of the air gate body 5 and the hot glass 1. The air blowing face of the air gate body 5 refers to the surface of the air gate body 5 blowing cold air towards the hot glass 1. Figure 1 The air blocking structure 7 can gather air when the air gate body 5 blows air towards the hot glass 1, can reduce the escape of the cold air blown by the air gate body 5 from the length direction of the air gate body 5, better maintain the air pressure of the glass air receiving area, and thus assist the air gate body 5 to blow the hot glass 1 with high efficiency. The glass air receiving area refers to the area in which the cold air is blown from the air gate body 5 to the air receiving surface of the hot glass 1.
[0044] Further specifically, the wind blocking structure 7 is a blocking plate. The outer edge contour of the blocking plate covers at least a part of the end face of the air grid body 5, and the blocking plate is arranged to extend towards the hot glass 1, so that the distance between the end of the blocking plate towards the hot glass 1 and the hot glass 1 is less than the distance between the blowing face of the air grid body 5 and the hot glass 1. Optionally, the blocking plate is a flat plate structure. In other embodiments, the outer edge contour of the blocking plate in each direction can all exceed the contour size of the end face of the air grid body 5, so that the blocking plate can completely cover and shield the opening at the end face of the air grid body 5.
[0045] In the present embodiment, the blocking plate is fixedly connected to the two ends of the air grid body 5, so that the blocking plate is in close contact with the end face of the air grid body 5. In other embodiments, the actual installation scene of the wind blocking structure 7 can be more flexible, for example, the blocking plate is fixed on the rack or other installation platform where the air grid body 5 is installed, at a position corresponding to the end of the air grid body 5, or the blocking plate is height-adjustably connected to the two ends of the air grid body 5, to adjust the relative height of the blocking plate and the air grid body, to adjust the wind blocking amount. At this time, there is a certain gap between the blocking plate and the end of the air grid body 5. However, as long as the blocking plate is in a position covering the two end faces of the air grid body 5, the gap between the blocking plate and the air grid body 5 does not affect the blocking plate to play a role of gathering wind to the glass wind receiving area.
[0046] In some other embodiments, the wind blocking structure 7 can be arranged on the two ends of part of the air grid bodies 5 in the lower air grid group 4, for example, on the air grid bodies 5 at the front half of the conveying roller 2, so as to rapidly cool the hot glass 1 at a high temperature, and the air grid bodies 5 at the rear half of the conveying roller 2 to cool the hot glass 1 more gently.
[0047] In some other embodiments, the outer edge contour of the blocking plate can only cover a part of the two end faces of the air grid body in the length direction of the lower air grid group, and the blocking plate is arranged to extend towards the hot glass 1, so that the distance between the side of the blocking plate close to the hot glass 1 and the hot glass 1 is less than the distance between the blowing face of the air grid body and the hot glass. The key is that the distance between the side of the blocking plate close to the hot glass 1 and the hot glass is less than the distance between the blowing face of the air grid body and the hot glass, to achieve the purpose of reducing the escape of the cooling air blown by the air grid body from the two sides of the air grid body in the length direction, to maintain the wind pressure of the glass wind receiving area. For example, in the lower air grid group, the blocking plate can be fixed on the upper half of the end face of the air grid body, and at this time, the two ends of the air grid body are closed.
[0048] The implementation principle of the above embodiments is as follows:
[0049] When the hot glass 1 moves on the conveyor roller 2, the air blocking structure 7 plays the role of gathering and concentrating the air. When the air grid body 5 blows air onto the hot glass 1, it can reduce the escape of cold air from both sides of the length direction of the air grid body 5, better maintain the wind pressure in the air-receiving area of the glass, and assist the air grid body 5 in blowing air onto the hot glass 1 efficiently, so that the hot glass 1 can be cooled quickly, thereby improving the tempering effect of the hot glass 1 and producing tempered glass of excellent quality.
[0050] Example 2
[0051] As attached Figure 5 As shown, this utility model discloses a tempering device for improving the quality of glass tempering. Unlike embodiment one, both ends of the wind grid body 5 in the upper wind grid group 3 and the lower wind grid group 4 are provided with wind-blocking structures 7.
[0052] Specifically, the wind-blocking structure 7 can be set at both ends of all the wind grating bodies 5 in the upper wind grating group 3 and the lower wind grating group 4, or it can be set only on some of the wind grating bodies 5 in the upper wind grating group 3 and the lower wind grating group 4 according to process requirements.
[0053] Example 3
[0054] As attached Figure 6 As shown, this utility model discloses a tempering device for improving the quality of glass tempering. Unlike embodiment one, the air blocking structure 7 is only set at both ends of the air grid body 5 in the upper air grid group 3.
[0055] Specifically, the wind-blocking structure 7 can be set at both ends of all the wind grating bodies 5 in the upper wind grating group 3, or it can be set only on some of the wind grating bodies 5 in the upper wind grating group 3 according to process requirements.
[0056] Example 4
[0057] Based on the above embodiments, taking Embodiment 1 as an example, the angle between the air blowing direction of the air blowing gap 51 and the vertical direction is denoted as θ. The range of θ is: θ≥20°. Since the air grating bodies 5 of the upper air grating group 3 are arranged with air pressure plates 6 and the air grating bodies 5 of the lower air grating group 4 are arranged with conveyor rollers 2 and the distance between them is also large, the angle θ between the air blowing direction of the air blowing gap 51 on the air grating body 5 and the vertical direction is larger, making it easier to achieve the goal of making the hot glass 1 more uniformly distributed by the air.
[0058] Furthermore, in actual production, it was found that the tempering effect of the hot glass 1 is optimal when the value of θ is in the range of 20°≤θ≤30°. This is because if θ is too large, the vertical wind pressure blown onto the surface of the hot glass 1 by the air curtain will be too small. The range of 20°≤θ≤30° makes it easier to achieve the goal of more uniform wind distribution on the hot glass 1, while ensuring the wind pressure and strength of the hot glass 1.
[0059] Embodiment five
[0060] As shown in the accompanying drawings, the utility model discloses a glass toughening equipment using the air grid body, on the basis of any one of the above embodiments, each air grid body 5 is provided with a wind guide structure 52. Figures 7-8 The wind guide structure 52 is located around the air blowing gap 51, so as to guide the cold air blown from the air blowing gap 51 and reduce the mutual influence of the cold air blown from the two air blowing gaps 51.
[0061] Specifically, the wind guide structure 52 in the embodiment is a wind guide plate. The wind guide plate is a long strip plate structure, and its length is the same as that of the air grid body 5. Two wind guide plates facing each other are arranged on the same air grid body 5, and the two wind guide plates are located between the two air blowing gaps 51 and close to the air blowing gaps 51. The wind guide plate can be vertically arranged or obliquely arranged. In the embodiment, the oblique direction of the wind guide plate is matched with the oblique angle of the air blowing gap 51, so as to guide the cold air flow to the greatest extent and guarantee the cooling effect on the hot glass 1.
[0062] In other embodiments, only one wind guide plate can be arranged between the two air blowing gaps 51, and the single wind guide plate can be arranged at the middle position between the two air blowing gaps 51.
[0063] Embodiment six
[0064] As shown in the accompanying drawings, the utility model discloses a glass toughening equipment using the air grid body, which is different from the embodiment five in that the air grid body 5 is further provided with an air equalizing plate 53.
[0065] Figure 9 The air equalizing plate 53 is a flat plate structure, and its size is matched with the air grid body 5 and is fixed inside the air grid body 5. A plurality of circular or other shape through holes are formed in the air equalizing plate 53, and the cold air in the air grid body 5 can only pass through the through holes in the air equalizing plate 53 and then be blown to the hot glass 1 from the air blowing gap 51. Therefore, the air equalizing plate 53 has a certain adjusting effect on the air volume passing through the air blowing gap 51 and the balance degree of air pressure at different positions.
[0066] For example, the area of the through hole at the position with high air pressure on the air equalizing plate 53 can be appropriately reduced, and the area of the through hole at the position with low air pressure on the air equalizing plate 53 can be appropriately enlarged, so that the air volume after passing through the air equalizing plate 53 tends to be balanced, and the cold air blown from different positions of the same air blowing gap 51 is more uniform, which is beneficial to improve the toughening effect of the hot glass 1.
[0067]
[0068] In some other embodiments, two or more layers of the uniform air distribution plates 53 with different shapes and sizes of the through holes and different positions can be arranged in the wind screen body 5 according to actual conditions, so as to further balance the air pressure at different positions in the wind screen body 5.
[0069] It should be noted that, in the above embodiments, the wind screen body can have the structure of both ends being open as shown in the drawings, or can have the structure of both ends being closed in the length direction on the basis of the structure of both ends being open. Figure 3 It should be noted that, in the above embodiments, the wind screen body can have the structure of both ends being open as shown in the drawings, or can have the structure of both ends being closed in the length direction on the basis of the structure of both ends being open. Figure 3 The purpose of the wind blocking structure is to maintain the air pressure of the wind receiving area, reduce the escape of the cooling air from the wind screen body after the cooling air from the air blowing gap of the wind screen body reaches the wind receiving area, relatively improve the wind pressure of the hot glass in the glass wind receiving area, and improve the cooling efficiency. In the drawings of the above embodiments, the conveying roller 2 is a metal roller, the surface of the metal roller is provided with aramid heat insulation ropes or heat insulation members of other materials and forms, or can not be provided with the heat insulation members.
