Technical Field

[0002] The existing glass tempering method is usually to heat the glass to a predetermined temperature in a heating furnace, and then directly send the heated high-temperature glass into a glass tempering device for cooling, tempering and forming. The existing glass tempering device is mainly composed of a conveying roller and an upper and lower air grille group. When the glass tempering device is working, the heated glass is conveyed by the conveying roller to pass between the upper and lower air grille groups. The upper and lower air grille groups blow cold air to the upper and lower surfaces of the glass respectively, and the hot glass is tempered by air cooling.

[0003] The wind grilles used in existing tempering equipment are all formed by opening holes in aluminum profiles to form air holes for blowing. The cooling air passes through the air holes and blows toward the high-temperature glass. Although there are existing technologies that mention opening air slits (also called air knives) on aluminum profiles to temper the glass with air, the actual application of the technology is rare. In actual production, it is found that the shape, position, and size of the air slits on the wind grilles will affect the tempering quality and tempering effect of the glass. The tempering quality of the glass cooled by the wind grille with a single air slit is not ideal, and further research and improvement are needed. Utility Model Content

DETAILED DESCRIPTION

[0060] The technical solutions in the embodiments of the present invention are described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "inner", "outer", "bottom", etc. used in this specification indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present application.

[0061] It should be noted that the embodiments of the present invention and the features involved in the embodiments can be combined with each other without conflict. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. It is worth noting that the plate in the present invention does not refer exclusively to a flat plate, but can also be a curved plate with a certain curvature.

[0062] Embodiment 1

[0063] As attached Figure 1As shown, a slit-type air-blowing air grille body 5 is used in a glass tempering device, which includes an upper air grille group 3, a lower air grille group 4 and a conveying roller 2, wherein the conveying roller 2 is used to support and convey the glass 1. The upper air grille group 3 and the lower air grille group 4 are each composed of a plurality of air grille bodies 5, and the air grille bodies 5 in the upper air grille group 3 and the lower air grille group 4 are arranged along the transmission direction of the conveying roller 2, and at least one of the upper air grille group and the lower air grille group is a slit-type air-blowing air grille body, so as to improve the cooling effect on the glass 1. When the glass 1 is conveyed on the conveying roller 2, the air grille bodies 5 in the upper air grille group 3 face downward to blow air to the glass 1, and the air grille bodies 5 in the lower air grille group 4 face upward to blow air to the glass 1.

[0064] The air grille body 5 of the slot-type air blowing is in the shape of a long strip, and its material can be selected from aluminum alloy. The air grille body 5 is provided with at least two air blowing slots.

[0065] In the present invention, the spacing between two adjacent blowing slits 524 is 10mm≤d≤150mm, the minimum width of the blowing slit 524 is 0.5mm≤w<3mm, the angle between the blowing direction of the blowing slit 524 and the vertical direction is α, and 0°≤α≤50°. In actual use, the wind grid body is generally arranged between two conveying rollers, and the glass is cooled by wind during the conveying process of the conveying rollers to complete the tempering. If the angle α between the blowing direction of the blowing slit 524 and the vertical direction is too large, the wind blown out of the blowing slit is easily deviated to the rotating conveying roller adjacent to the wind grid body, thereby generating obvious eddy currents, resulting in uneven cooling flow field and affecting the glass tempering quality. Therefore, 0°≤α<30° is more preferred. In addition, unreasonable arrangement of the distance between adjacent blowing slits will lead to uneven distribution of the overall cooling wind blowing flow field. Too close distance between adjacent blowing slits will increase the difficulty of structural design and processing. Too far distance between adjacent blowing slits will result in insufficient wind-receiving area and wind-receiving time for the glass. The tempering quality is not high, so the spacing between two adjacent blowing gaps is preferably 10mm≤d≤85mm; and the minimum width of the blowing gap is selected. If it is too small, the processing difficulty will be too great and the wind pressure will be too concentrated to affect the flatness of the glass. If the minimum width is too large, the wind pressure of the blowing gap will be insufficient to affect the tempering degree of the glass. Therefore, the minimum width of the blowing gap is preferably 0.5mm≤w≤2.5mm. The parameter setting of this embodiment can ensure the uniformity of the blowing distribution and weaken the eddy current, so that the blowing gap distribution is denser and more uniform, and the blowing coverage area of ​​the tempered glass is also larger, thereby improving the tempering quality.

[0066] In this embodiment, the distance between two adjacent blowing slits 524 on the wind grille body 5 is 10 mm or 25 mm; the minimum width of the blowing slit 524 is 1 mm or 1.5 mm, and the angle α between the blowing direction of the blowing slit 524 and the vertical direction is 0°.

[0067] In this embodiment, the blowing slit is a long continuous strip extending along the length direction of the wind grille body. Preferably, the continuous long slit refers to a slit with an aspect ratio of more than 200:1, which can better perform blowing tempering on the glass. Alternatively, the blowing slit is composed of a plurality of short slits arranged at intervals along the length direction of the wind grille body.

[0068] In this embodiment, two blowing slits 524 are arranged on the wind grid body 5 used for the glass tempering equipment. The blowing slits 524 set according to the above parameters have good blowing effect, and the blowing slits 524 are densely distributed and more uniform. The blowing coverage area of ​​the glass is also larger, so that the glass surface is cooled more evenly. During the conveying and cooling process of the glass 1, compared with the prior art, the same size of glass is conveyed on the conveying roller for the same distance to be tempered by the wind. The wind grid body can make the wind pressure of the glass more uniform, the wind-receiving area at the same time larger, and the wind-receiving time longer. Therefore, the particle size, flatness, and waveform of the glass 1 after cooling and tempering are better, the wind spots are weaker, and the final glass tempering quality is higher.

[0069] Embodiment 2

[0070] Further settings, such as Figure 2-4 As shown, the wind grid body 5 includes a wind grid wall 51 and a wind stabilizing structure 52 located inside the wind grid wall 51, the wind stabilizing structure 52 cooperates with the wind grid wall 51 to form at least two circulation channels, the blowing slits 524 are provided on the wind grid wall 51, and each of the circulation channels 523 is connected to a blowing slit. In this embodiment, the wind stabilizing structure 52 is integrally arranged with the wind grid wall 51. In other embodiments, the wind stabilizing structure 52 may also be a separate structure from the wind grid wall 51, and the wind stabilizing structure 52 is assembled into the wind grid wall 51 after being processed. The wind grid wall 51 refers to the profile wall where the outer contour of the wind grid body is located. On the one hand, the wind stabilizing structure strengthens the structural strength of the wind grid body, and on the other hand, the wind stabilizing structure can allow the cooling wind to be diverted into multiple sub-cooling winds corresponding to the blowing slits one by one, so that the wind pressure blown out of each blowing slit is more stable and more uniform, which is beneficial to improving the tempering quality of the glass. If there is no wind stabilizing structure, the cooling wind will form a vortex after entering the wind grid wall, and the blowing wind pressure of the two blowing gaps cannot be kept stable and uniform.

[0071] In this embodiment, the cross section of the wind grille wall 51 is U-shaped as a whole, with an open top and two sides and a bottom that are semi-enclosed structures.

[0072] Specifically, the wind stabilizing structure 52 includes a connecting structure 521 and an air distribution component 522 .

[0073] The connection structure 521 is a perforated plate structure disposed inside the wind grille wall 51. In this embodiment, the perforated plate structure may optionally include a plurality of rectangular holes, with ribs between two adjacent rectangular holes, so as to strengthen the structural strength of the wind grille body 5 and ensure the structural stability of the wind grille body during long-term use. Alternatively, the perforated plate structure may optionally include a plurality of rows of circular holes, which may further improve the uniformity of the cooling air outlet in the length direction of the wind grille body.

[0074] The length direction of the air distribution component 522 is the same as the length direction of the wind grid body 5, and the length of the air distribution component 522 is the same as the length of the wind grid body 5. The top of the air distribution component 522 is fixedly connected to the connection structure 521, and the bottom of the air distribution component 522 is fixedly connected to the bottom of the wind grid wall 51, so that the air distribution component 522 is supported and fixed inside the wind grid wall 51. The air distribution component 522 is used to divide the cooling air entering the wind grid body 5 into multiple sub-cooling air corresponding to the blowing slits 524, so that the wind pressure blown out of each blowing slit 524 is more stable and more uniform.

[0075] The air distribution component 522 cooperates with the wind grid wall 51 to form at least two circulation channels 523 in the space inside the wind grid wall 51. The length direction of the circulation channels 523 is the same as the length direction of the wind grid body 5. Each circulation channel 523 is connected to a blowing gap 524.

[0076] In this embodiment, the blowing gap 524 is a long, continuous gap in a long strip shape. In other embodiments, the blowing gap 524 can also be formed by a plurality of short gaps arranged at intervals to form a long gap.

[0077] In particular, in the present application, the width of the blowing slit 524 on the wind grille body 5 can be set to have a certain change along the blowing direction of the cooling air, and can be trumpet-shaped or of equal width as a whole. Therefore, the minimum width of the blowing slit 524 in the present invention refers to the minimum width of the blowing slit 524 along the blowing direction of the cooling air. If the blowing slit is trumpet-shaped, the minimum width refers to the narrowest width of the trumpet-shaped blowing slit.

[0078] In this embodiment, the air distribution component 522 is arranged in an inverted Y shape, including two air distribution plates. The two air distribution plates cooperate with the wind grid wall 51 to form two left and right circulation channels 523. The circulation channels 523 are connected to the blowing gap 524.

[0079] Embodiment 3

[0080] As attached Figure 5-7As shown, a wind grille body disclosed in the utility model is different from the wind grille body in the first embodiment in that the connection structure 521 is tilted, the wind distribution assembly 522 is arranged in an inverted V shape, and includes two wind distribution plates; and the spacing between two adjacent blowing slits 524 on the wind grille body 5 is 35mm or 60mm, which refers to the spacing between the air outlets of the two blowing slits 524; the minimum width of the blowing slit 524 is 1.5mm or 2mm, and the angle α between the blowing direction of the blowing slit 524 and the vertical direction is 20° or 10°. The glass tempering equipment using this wind grille body 5 can also achieve high-quality tempering of glass.

[0081] Embodiment 4

[0082] As attached Figure 8-10 As shown, a wind grid body disclosed in the utility model is different from the wind grid body in the first embodiment in that the wind distribution component 522 includes a wind distribution plate and is vertically arranged; the wind distribution component 522 cooperates with the wind grid wall 51 to form two left and right circulation channels 523, and two blowing slits 524 are respectively connected to the two circulation channels 523; and the spacing between two adjacent blowing slits 524 on the wind grid body 5 is 85mm or 100mm, which refers to the spacing between the air outlets of the two blowing slits 524; the minimum width of the blowing slit 524 is 3mm or 2mm, and the angle α between the blowing direction of the blowing slit 524 and the vertical direction is 25° or 35°. The glass tempering equipment using this wind grid body 5 can also achieve high-quality tempering of glass.

[0083] Embodiment 5

[0084] As attached Fig.11 As shown, a slit-type wind grille body for blowing air is disclosed in the utility model. Different from the wind grille body in the second embodiment, the air distribution component 522 includes two air distribution plates, and the two air distribution plates cooperate with the wind grille wall 51 to form three circulation channels 523, including two left and right circulation channels 523 and a circulation channel 523 between the two air distribution components 522.

[0085] Each flow channel is connected to a corresponding blowing gap arranged on the wind grid wall. The glass tempering equipment using the wind grid body 5 can also achieve high-quality tempering of glass.

[0086] Embodiment 6

[0087] The present utility model also provides a wind grille body, which is different from any one of the embodiments one to five in that the wind grille body is a combined wind grille body, and the combined wind grille body includes two sub-wind grille bodies, and the two sub-wind grille bodies are formed by left-right splicing or up-down splicing.

[0088] In this embodiment, Fig.12The combined wind grille body includes two sub-wind grille bodies 53 spliced ​​on the left and right, each sub-wind grille body is provided with a blowing slit, and the two sub-wind grille bodies 53 are connected as a whole by a connecting piece. This structural method can also realize the provision of two blowing slits on the wind grille body, so that the blowing slits are distributed more densely and more evenly, thereby improving the tempering quality of the glass. The spacing between the two blowing slits is 120mm; the minimum width of the blowing slit 524 is 3mm or 2mm, and the angle α between the blowing direction of the blowing slit 524 and the vertical direction is 0°

[0089] The position of the connecting member is optional. For example, the connecting member can be a connecting plate, which plays a connecting role between the two blowing gaps of the two sub-grid bodies. It can also prevent broken glass from falling between the two sub-grid bodies when the distance between the two sub-grid bodies is too close, making it difficult to clean. In other embodiments, the connecting member can also be a connecting rod or a connecting bolt. In addition, the two sub-grid bodies can also be connected by threaded connection, plug-in connection, riveting or welding.

[0090] In other embodiments, Fig.13 The combined wind grille body comprises two sub-wind grille bodies 53 spliced ​​up and down, and the two sub-wind grille bodies are connected by threads, specifically by screws. Alternatively, the two sub-wind grille bodies can also be connected by plug-in connection, riveting or welding.

[0091] It should be noted that if Fig.14 An external splicing unit may be provided on the air inlet side of the wind grille body, and the external splicing unit may be connected to the wind grille body by plugging. Alternatively, the external splicing unit may be connected to the wind grille body by screw threads or the like. The splicing unit may be connected to the wind box of the tempering equipment.

[0092] Embodiment 7

[0093] The width of the blowing gap in the above embodiment can be fixed. The utility model also provides a wind grille body, such as Fig.15 The width of the blowing gap can be adjusted by an adjustment component. Specifically, the initial width of the blowing gap is relatively large, and the width of the blowing gap required by different tempering processes can be adjusted by the adjustment component. The adjustment component can be an adjustment screw, and the expansion degree of the wind grid walls on both sides of the blowing gap can be adjusted by adjusting the screw to adjust the accurate width of the gap to adapt to the glass blowing tempering requirements.

[0094] In this embodiment, the minimum width of the blowing gap defines the gap width after the final adjustment, rather than the initial width of the blowing gap that has not been adjusted when there is no constraint of the adjustment component.

[0095] Embodiment 8

[0096] The present utility model also provides a glass tempering equipment, which is different from the first embodiment in that, among the wind grille bodies in the upper wind grille group and the lower wind grille group, the wind grille body on the inlet side of the tempering equipment is a wind hole type wind grille body, and the remaining wind grille bodies are the slit type blowing wind grille bodies described in any of the above embodiments, and the wind hole type wind grille body is a wind grille with blowing holes in the prior art.

[0097] The blowing air holes of the air hole type wind grille body are generally circular through holes. In particular, there can be one or more air hole type wind grille bodies, which are arranged at the inlet side of the tempering equipment, and the air grille bodies with slit type blowing are still used at other positions. The inlet side is not necessarily the outside of the first roller, but can also be close to the glass entry side. There are multiple air hole type wind grille bodies. For the lower wind grille group, each air hole type wind grille body can be arranged between two conveying rollers.

[0098] The slit-type air-blowing wind grille body and the air-hole-type wind grille body are used in combination to cool the high-temperature glass 1. The glass tempering equipment in this embodiment is particularly suitable for cooling glass with a thickness of less than 6 mm. Its cooling effect is better than the cooling effect of the glass tempering equipment using any one of the slit-type air-blowing wind grille bodies 5 in Examples 1-7 alone or the glass tempering equipment using the wind grille with air blowing holes alone, and can further improve the cooling effect.

[0099] It should be noted that the number of one or two wind splitters refers to the composition from the cross section of the wind grid, and in the length direction of the wind grid body, that is, the length direction of the wind splitters, each wind splitter can be continuous, and each wind splitter can also be discontinuous, that is, composed of multiple sub-parts, which is also feasible. In the above embodiment, the upper wind grid group and the lower wind grid group are different manifestations of the setting position of the wind grid group.

[0100] It should be noted that the wind grille wall in Examples 2 to 5 is a whole, and the combined wind grille body in Example 6 can also be used.
