Description

A slit-type air-blowing wind grid body, wind grid assembly, and glass tempering equipment Technical Field

[0001] The utility model relates to the field of tempered glass production equipment, in particular to a slit-type air-blowing air grid body and glass tempering equipment using the air grid body. Background Art

[0002] Existing glass tempering methods typically heat the glass to a predetermined temperature in a furnace, then feed the heated, high-temperature glass directly into a glass tempering unit for cooling, tempering, and shaping. Existing glass tempering units primarily consist of a conveyor roller conveyor and upper and lower air grids. During operation, the heated glass is conveyed by the conveyor roller conveyor between the upper and lower air grids, which blow cold air onto the upper and lower surfaces of the glass, respectively. This air-cooling process results in tempering the hot glass.

[0003] Existing wind grilles used in tempering equipment all use holes in the aluminum profile to create air holes. Cooling air passes through these holes and is then blown onto the hot glass. Although existing technology mentions using air slits (also called air knives) in aluminum profiles to temper glass, this technology has been rarely used in practice. In actual production, it has been found that the shape, position, and size of the air grille slits can affect the tempering quality and effectiveness of the glass. The tempering quality of glass cooled using air grilles with a single air slit is not ideal, and further research and improvement are needed. Utility Model Content

[0004] In view of the problem existing in the prior art: the tempered quality of glass cooled by a single air knife wind grid is not ideal, the purpose of the present utility model is to provide a slit-type blowing wind grid body.

Therefore, after the glass is tempered by blowing, the granularity, flatness, and waveform of the glass are better, the wind spots are weaker, and the tempered glass quality is higher.

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 only a part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "up", "down", "inside", "outside", "bottom", etc. used in this specification to indicate directions or positional relationships are based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present application.

[0061] It should be noted that the embodiments of this utility model and the features involved in the embodiments may be combined with each other without conflict. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort shall fall within the scope of protection of this utility model. It is worth noting that the plate in this utility model does not refer exclusively to a flat plate; it may also be a curved plate with a certain curvature. Example

[0062] As shown in FIG1 , a slit-type air-blowing air grille body 5 is used in glass tempering equipment, which includes an upper air grille group 3, a lower air grille group 4, and a conveyor roller 2, wherein the conveyor 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 conveyor roller 2. At least one air grille body in each of the upper air grille group 3 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. During the process of conveying the glass 1 on the conveyor roller 2, the air grille bodies 5 in the upper air grille group 3 face downward to blow air toward the glass 1, and the air grille bodies 5 in the lower air grille group 4 face upward to blow air toward the glass 1.

[0063] The air grille body 5 of the slot-type blowing is in the shape of an elongated strip and can be made of aluminum alloy. The air grille body 5 is provided with at least two air blowing slots.

[0064] In the present invention, the spacing between two adjacent blowing slits 524 is 10mm≤d≤150mm, the minimum width of the blowing slits 524 is 0.5mm≤w<3mm, and the angle between the blowing direction of the blowing slits 524 and the vertical direction is α, and 0°≤α≤50°. In actual use, the wind grid body is generally installed between two conveyor rollers, and the glass is cooled by the wind and tempered during the conveyor roller process. 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 will easily deviate to the rotating conveyor roller adjacent to the wind grid body, thereby generating obvious eddy currents, resulting in uneven cooling flow field and affecting the quality of glass tempering. Therefore, it is more preferred that 0°≤α<30°; in addition, unreasonable arrangement of the distance between adjacent blowing slits will lead to uneven distribution of the overall cooling air blowing flow field. If the distance between adjacent blowing slits is too close, the design and processing of the structure will increase. If the distance between adjacent blowing slits is too far, the wind-receiving area and wind-receiving time of the glass will be insufficient. The tempering quality is not high, so the spacing between two adjacent blowing slits is preferably 10mm≤d≤85mm; and the minimum width of the blowing slit 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 slit will be insufficient to affect the tempering degree of the glass. Therefore, the minimum width of the blowing slit 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 slit distribution is denser and more uniform, and the blowing coverage area of ​​the tempered glass is also larger, thereby improving the tempering quality.

[0065] In this embodiment, the distance between two adjacent blowing slits 524 on the air 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°.

[0066] In this embodiment, the blowing slit is a continuous strip extending along the length of the air grille body. Preferably, the continuous strip has an aspect ratio of 200:1 or greater, which can better temper the glass. Alternatively, the blowing slit can be composed of multiple short slits spaced apart along the length of the air grille body.

[0067] In this embodiment, the wind grid body 5 used for the glass tempering equipment is provided with two blowing slits 524. The blowing slits 524 set according to the above parameters have a good blowing effect, and the blowing slits 524 are densely distributed and more evenly distributed, and 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 existing technology, the same size of glass is conveyed the same distance on the conveyor roller to be tempered by the wind. The wind grid body can make the wind pressure of the glass more uniform, the wind-exposed area at the same time larger, and the wind-exposed 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. Example

[0068] Further configuration, as shown in Figures 2-4, 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 opened 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 integrated with the wind grid wall 51. In other embodiments, the wind stabilizing structure 52 can 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 processing. 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 divert the cooling air into multiple sub-cooling air 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 vortices after entering the wind grid wall, and the blowing wind pressure of the two blowing gaps cannot be kept stable and uniform.

[0069] In this embodiment, the cross section of the wind grid wall 51 is U-shaped as a whole, with an open top and semi-enclosed structures on both sides and the bottom.

[0070] Specifically, the wind stabilizing structure 52 includes a connecting structure 521 and an air distribution component 522 .

[0071] The connecting structure 521 is a perforated plate structure disposed within the air grille wall 51. In this embodiment, the perforated plate structure optionally includes multiple rectangular holes, with ribs between adjacent rectangular holes to enhance the structural strength of the air grille body 5 and ensure its stability during prolonged use. Alternatively, the perforated plate structure may include multiple rows of circular holes to further improve the uniformity of cooling air flow along the length of the air grille body.

[0072] The length of the air distribution assembly 522 is the same as the length of the wind grid body 5, and the length of the air distribution assembly 522 is the same as the length of the wind grid body 5. The top of the air distribution assembly 522 is fixedly connected to the connecting structure 521, and the bottom of the air distribution assembly 522 is fixedly connected to the bottom of the wind grid wall 51, thereby supporting and fixing the air distribution assembly 522 inside the wind grid wall 51. The air distribution assembly 522 is used to divide the cooling air entering the wind grid body 5 into multiple sub-cooling air streams corresponding to the blowing slits 524, thereby making the air pressure blown out of each blowing slit 524 more stable and uniform.

[0073] 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 .

[0074] In this embodiment, the blowing slit 524 is a long, continuous slit. In other embodiments, the blowing slit 524 can also be formed by a plurality of short slits arranged at intervals to form a long slit.

[0075] In particular, in the present application, the width of the blowing slit 524 on the wind grid 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.

[0076] 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. Example

[0077] As shown in Figures 5-7, a wind grille body disclosed in the present invention differs from the wind grille body in Example 1 in that the connecting structure 521 is tilted, the air distribution assembly 522 is arranged in an inverted V shape, and includes two air distribution plates. Furthermore, the spacing between two adjacent blowing slits 524 on the wind grille body 5 is 35 mm or 60 mm, referring here to the spacing between the air outlets of the two blowing slits 524. The minimum width of the blowing slits 524 is 1.5 mm or 2 mm, and the angle α between the blowing direction of the blowing slits 524 and the vertical direction is 20° or 10°. Glass tempering equipment using this wind grille body 5 can also achieve high-quality tempering of glass. Example

[0078] As shown in Figures 8-10, a wind grid body disclosed in the present invention differs from the wind grid body in Example 1 in that the wind distribution assembly 522 includes a vertically disposed wind distribution plate. The wind distribution assembly 522 cooperates with the wind grid wall 51 to form two left and right circulation channels 523, with two blowing slits 524 connected to the two circulation channels 523, respectively. The spacing between two adjacent blowing slits 524 on the wind grid body 5 is 85 mm or 100 mm, referring here to the spacing between the air outlets of the two blowing slits 524. The minimum width of the blowing slits 524 is 3 mm or 2 mm, and the angle α between the blowing direction of the blowing slits 524 and the vertical direction is 25° or 35°. Glass tempering equipment using this wind grid body 5 can also achieve high-quality tempering of glass. Example

[0079] As shown in Figure 11, a slit-type wind grid body for blowing is disclosed in the present invention. Different from the wind grid body in Example 2, the air distribution component 522 includes two air distribution plates, and the two air distribution plates cooperate with the wind grid 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.

[0080] Each flow channel is connected to a corresponding blowing gap arranged on the wall of the wind grid. The glass tempering equipment using this wind grid body 5 can also achieve high-quality tempering of glass. Example

[0081] The present invention also provides a wind grid body, which is different from any one of the embodiments from the first to the fifth embodiment in that the wind grid body is a combined wind grid body, and the combined wind grid body includes two sub-wind grid bodies, and the two sub-wind grid bodies are formed by left-right splicing or up-down splicing.

[0082] In this embodiment, as shown in Figure 12, the combined wind grille body includes two sub-wind grille bodies 53 spliced ​​together 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 connector. This structural method can also achieve the goal of providing two blowing slits on the wind grille body, making the blowing slits more densely distributed and more evenly distributed, thereby improving the tempering quality of the glass. The spacing between the two blowing slits is 120 mm; the minimum width of the blowing slit 524 is 3 mm or 2 mm, and the angle α between the blowing direction of the blowing slit 524 and the vertical direction is 0°

[0083] The location of the connector is optional. For example, the connector can be a connecting plate that connects the two air vents of the two sub-grid bodies. This serves to prevent broken glass from falling between the two sub-grid bodies when the two sub-grid bodies are too close, making it difficult to clean. In other embodiments, the connector can also be a connecting rod or a connecting bolt. Furthermore, the two sub-grid bodies can be connected using threaded connections, plug-in connections, riveting, or welding.

[0084] In other embodiments, as shown in FIG13 , the combined wind grid body includes two sub-wind grid bodies 53 spliced ​​together, the two sub-wind grid bodies being connected by threads, specifically screws. Alternatively, the two sub-wind grid bodies can also be connected by plug-in connection, riveting, or welding.

[0085] It should be noted that, as shown in Figure 14, an external splicing unit can be installed on the air inlet side of the wind grille body. The external splicing unit is connected to the wind grille body via a plug-in connection. Alternatively, the external splicing unit can be connected to the wind grille body via screw threads or other methods. The splicing unit can be connected to the wind box of the tempering equipment. Example

[0086] While the width of the blowing slit described in the above embodiment can be fixed, the present invention further provides a wind grille body, as shown in Figure 15 , in which the width of the blowing slit can be adjusted via an adjustment assembly. Specifically, the initial width of the blowing slit is relatively large, and the adjustment assembly can be used to adjust the specific blowing slit width required by different tempering processes. The adjustment assembly can be an adjustment screw that adjusts the tightness of the wind grille walls on both sides of the blowing slit, thereby adjusting the precise width of the slit to suit the requirements of glass tempering.

[0087] In this embodiment, the minimum width of the blowing gap defines the final adjusted gap width, rather than the initial width of the blowing gap that has not been adjusted when there is no constraint of the adjusting component. Example

[0088] The present utility model also provides a glass tempering equipment, which is different from the first embodiment in that, among the wind grid bodies in the upper wind grid group and the lower wind grid group, the wind grid body on the inlet side of the tempering equipment is a wind hole type wind grid body, and the remaining wind grid bodies are the slit type blowing wind grid bodies described in any of the above embodiments. The wind hole type wind grid body is a wind grid with blowing holes in the prior art.

[0089] The air holes in the vent-type air grille are generally circular through-holes. Specifically, there can be one or more vent-type air grilles, each located at the inlet side of the tempering equipment. Slot-type air grilles are used in other locations. The inlet side doesn't necessarily have to be outside the first roller; it can also be near the glass entrance. Multiple vent-type air grilles can be used. For the lower air grille group, each vent-type air grille can be located between two conveyor rollers.

[0090] The slit-type blowing wind grid body and the wind hole-type wind grid 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 blowing wind grid bodies 5 in Examples 1-7 alone or the glass tempering equipment using the wind grid with blowing holes alone, and can further improve the cooling effect.

[0091] It should be noted that the presence of one or two air dividers refers to the composition viewed from the cross-section of the wind grille. In the longitudinal direction of the wind grille body, i.e., the longitudinal direction of the air dividers, each air divider can be continuous or discontinuous, i.e., composed of multiple sub-sections, which is also feasible. In the above embodiment, the upper wind grille group and the lower wind grille group represent different representations of the placement of the wind grille group.

[0092] It should be noted that the wind grille wall in Examples 2 to 5 is a single unit, and the combined wind grille body in Example 6 can also be used. In addition, the wind grille wall in Examples 2 to 5 can be a single-layer wind grille wall as shown in the corresponding drawings, which is replaceable and deformable. The wind grille wall can also be a sandwich hollow structure including multiple layers of boards. The key is that the wind grille wall and the wind stabilizing structure form multiple circulation channels. All of the above solutions are within the scope of protection.

[0093] It should be noted that the combined wind grille body can also be modified by splitting the structure based on the structure of the above embodiment.
