[0002] In the field of glass deep processing technology, the design and operation of glass conveyor lines are crucial. Glass conveyor lines typically require conveying mechanisms and air blowing equipment to ensure smooth glass transport and uniform cooling. Air vents are an important type of ventilation equipment; their main function is to exhaust air at a specific angle onto the glass surface heated to over 620°C to provide the cooling air required for the tempering process.

[0003] In related technologies, conveyor production lines typically employ rigid air grating structures, composed of multiple grating blocks. These grating blocks control the airflow by raising and lowering. However, this rigid air grating structure is prone to turbulence and uneven airflow when raised, resulting in poor stress uniformity in physically curved tempered glass. Utility Model Content

To this end, this invention proposes a curved air vent, formed by opening air outlets in a flexible metal tube, which can eliminate the wind turbulence problem generated when a rigid air vent is pulled up, thereby improving the quality and stability of glass production.

[0013] The bending tempered glass forming equipment according to the embodiments of this utility model has at least the following beneficial effects: the bending air grid formed by opening air outlets in a metal flexible tube is used as the upper air grid and / or lower air grid. The bending of the air grid itself better conforms to the shape of the curved glass, thereby ensuring the gap with the surface of the glass to be processed; and even when the bending air grid is in a bent state, the air outlets tend to be evenly distributed, which helps to eliminate the wind disturbance problem generated when the rigid air grid is pulled up, and makes the air blown by the bending air grid more evenly act on the glass surface; thereby improving the stress uniformity of the glass surface, the quality and stability of glass production.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] In a first aspect, this utility model provides a curved air grille, which is applied to one of the upper air grille assembly and the lower air grille assembly of a curved tempered glass forming equipment.

[0039] like Figures 1 to 4 As shown, in some embodiments, the curved air duct 100 includes a flexible metal hose 110, at least a portion of which is bendable to form a shape that conforms to the requirements of curved glass. The curved air duct 100 uses the flexible metal hose 110 as its main structure, allowing it to bend to form the shape required for curved glass. Furthermore, by adjusting the bending position and curvature of the curved air duct 100, it can adapt to glass with different curved shapes, making it more consistent with the glass surface shape and improving the blowing effect and tempering quality. The side wall of the flexible metal hose 110 has an air inlet 111, which communicates with the air collection box 200, facilitating the smooth entry of air into the air duct. On the side of the flexible metal hose 110 opposite to the air inlet 111, multiple air outlets 112 are arranged axially at intervals, with adjacent air outlets 112 staggered; this achieves a more uniform airflow effect and reduces turbulence.

[0040] In this embodiment, a curved air grille 100 is formed by opening air outlets 112 in a metal flexible hose 110. The curved air grille 100 can better conform to the shape of the curved glass by bending itself, thereby ensuring the gap with the surface of the glass to be processed. Even when the curved air grille 100 is in a bent state, the air outlets 112 tend to be evenly distributed, making the air blowing more uniform. This avoids the phenomenon that there is no air outlet structure between two adjacent rigid air grilles when the rigid air grille is pulled up. It helps to eliminate the wind disturbance problem generated when the rigid air grille is pulled up, so that the air blowing of the curved air grille 100 acts more evenly on the glass surface. This improves the stress uniformity of the glass surface, the quality and stability of glass production.

[0041] In some embodiments, such as Figure 1 , Figure 3 and Figure 4As shown, the multiple air outlets 112 include multiple first air outlets 1211 and multiple second air outlets 1212. Along the axial direction of the curved air grille 100, the first air outlets 1211 and second air outlets 1212 are alternately arranged, and the air outlet directions of the first air outlets 1211 and second air outlets 1212 are arranged at an angle. Through the alternation and angled arrangement of the first air outlets 1211 and second air outlets 1212, multi-dimensional and multi-directional airflow can be achieved, thereby covering a wider area.

[0042] In this embodiment, the axial direction refers to the extension direction of the flexible metal hose 110, and the circumferential direction refers to the outer circumference of the flexible metal hose 110. It should be noted that the flexible metal hose 110 in this embodiment is not necessarily a circular tube; it may also form an arc-shaped sidewall only at the location of the air outlet 112. In this embodiment, the circumferential direction refers to the arc length of the arc-shaped sidewall. Setting the surface of the air outlet 112 as arc-shaped allows the air outlet directions of the first air outlet 1211 and the second air outlet 1212 to form a certain angle.

[0043] Specifically, multiple first air vents 1211 are spaced apart along the axial direction, and at least two second air vents 1212 are spaced apart circumferentially between any two adjacent first air vents 1211. The first air vents 1211 and second air vents 1212 are staggered. That is, the curved air grille 100 is divided into multiple air outlet positions along the axial direction. In two adjacent air outlet positions, one air outlet position is provided with a first air vent 1211, and the other air outlet position is provided with two circumferentially spaced second air vents 1212. The first air vents 1211 are directly opposite the gap between the two second air vents 1212 along the circumferential direction, so that the air outlet angles of the first air vents 1211 and the second air vents 1212 are set at a certain angle. This layout helps to reduce local turbulence caused by the excessive concentration of air outlets 112, while improving the dispersion and uniformity of air flowing out of the curved air grille 100.

[0044] In other embodiments, in two adjacent air outlet positions, one air outlet position is provided with three circumferentially spaced first air holes 1211, and the other air outlet position is provided with two circumferentially spaced second air holes 1212, with the first air holes 1211 and the second air holes 1212 being staggered. Alternatively, the multiple air outlets 112 may include multiple first air holes 1211, multiple second air holes 1212, and multiple third air holes, with the first air holes 1211, second air holes 1212, and second air holes 1212 being sequentially provided in three adjacent air outlet positions, and the first air holes 1211, second air holes 1212, and third air holes being staggered; this application does not limit this.

[0045] like Figure 1 and Figure 4As shown, each air outlet 112 is an axially extending strip-shaped hole. This strip-shaped design allows for a more uniform and stable airflow as air exits the curved air grille 100. Compared to circular holes, the strip-shaped holes provide a larger air outlet area, thus reducing localized turbulence caused by excessively small air outlets 112. Since the curved air grille 100 can be bent to conform to the shape requirements of curved glass, the strip-shaped hole design better adapts to glass with different curved shapes. This helps ensure that the airflow direction remains perpendicular to the glass surface, further improving the tempering quality.

[0046] Based on the above embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the curved air grille 100 also includes an air distribution element 113, which is disposed between the air inlet 111 and the air outlet 112. The air distribution element 113 is used to evenly distribute the airflow entering the curved air grille 100 and to balance the airflow volume of each air outlet 112. The air distribution element 113 can disperse and guide the airflow from the air collection box 200 to each air outlet 112, ensuring that each air outlet 112 receives a uniform airflow supply and avoiding uneven airflow caused by excessively strong or weak local airflow.

[0047] The specific implementation of the air distribution component 113 can be designed according to the structure of the curved air grid 100 and the air blowing requirements. For example, a perforated plate, a guide plate, or an adjustable air distribution device can be selected to effectively disperse and guide the airflow and achieve a uniform airflow distribution effect.

[0048] In one embodiment, the air distribution element 113 adopts a combination of a perforated plate and a guide plate. Specifically, the air distribution element 113 includes a wind-blocking portion 1131 and air-guided portions 1132 connected to both ends of the wind-blocking portion 1131. Both the wind-blocking portion 1131 and the air-guided portions 1132 have air distribution holes. The wind-blocking portion 1131 is positioned directly opposite the air inlet 111, meaning it faces the airflow from the air collection box 200. The air distribution holes on the wind-blocking portion 1131 can disperse the airflow from the air collection box 200, preventing the airflow from directly impacting the air outlets 112 and causing excessively strong local airflow. The air-guided portions 1132 can guide the airflow along a specific path, increasing the airflow at both ends of the air distribution element 113, thereby homogenizing the airflow distribution from the middle to both ends of the air distribution element 113 and ensuring that the airflow is evenly distributed to each air outlet 112. After being processed by the air distribution element 113, the airflow can be evenly distributed to each air outlet 112, improving the uniformity and stability of the blowing effect.

[0049] Because the curved air grille 100 has a relatively long axial dimension, multiple air collection boxes 200 can be arranged along the axial direction to more effectively distribute and transport airflow. These air collection boxes 200 are evenly distributed axially, ensuring a more uniform airflow into the curved air grille 100. Each air collection box 200 is equipped with a corresponding air inlet 111. The air inlet 111 is connected to the air collection box 200 via a pipe or other connecting structure, such as a P84 fiber high-temperature resistant cloth bag. Each air inlet 111 is correspondingly equipped with an air distribution element 113, positioned directly opposite the air inlet 111. The design of the air distribution element 113 can refer to the previously mentioned combination of perforated plate and guide plate scheme, achieving uniform airflow distribution by dispersing and guiding the airflow.

[0050] For metal flexible hose 110, stainless steel flexible hoses can be selected. Stainless steel flexible hoses have a simple structure, are easy to manufacture and maintain, which helps to reduce production costs and improve economic efficiency. In addition, stainless steel flexible hoses have strong corrosion resistance and long service life, which helps to improve the reliability and stability of ventilation equipment.

[0051] Secondly, this utility model also provides a device for bending tempered glass. For example... Figure 1 and Figure 5 As shown, in some embodiments, the tempered glass bending forming equipment includes a conveying mechanism 300a, an upper air grid assembly, and a lower air grid assembly. The conveying mechanism 300a includes a plurality of conveying rollers 300, which are spaced apart along a first direction perpendicular to the axial direction of the conveying rollers 300. The conveying rollers 300 convey the glass by rotating, ensuring that the glass can pass smoothly and continuously through the entire forming equipment. The first direction is the glass conveying direction.

[0052] The upper air grating assembly includes multiple upper air grates 100a, and the lower air grating assembly includes multiple lower air grates 100b. The lower air grates 100b are arranged opposite to the upper air grates 100a, and the lower air grates 100b are alternately arranged with the conveyor rollers 300. This alternating arrangement ensures that the glass between each conveyor roller 300 is subjected to the blowing action of the curved air grates 100, thereby achieving uniform glass forming.

[0053] The curved air grate 100 described in the first aspect can be used as the upper air grate 100a or the lower air grate 100b of the tempered glass forming equipment. Because the curved air grate 100 is formed by opening air holes 112 in the metal flexible hose 110, its own bending better conforms to the shape of the curved glass. Furthermore, the top of the lower air grate 100b should be lower than the top of the conveyor roller 300, thus ensuring a gap with the surface of the glass to be processed. This also makes the airflow from the curved air grate 100 more uniform, which helps eliminate the turbulence caused by rigid air grates when pulled up, improving the stress uniformity of the glass surface and the quality and stability of glass production.

[0054] The following description of the wind grating 100b uses the curved wind grating 100 as described in the first aspect as an example.

[0055] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the multiple air outlets 112 include multiple first air outlets 1211 and multiple second air outlets 1212. The multiple first air outlets 1211 are spaced apart along the axial direction, and at least two second air outlets 1212 are spaced apart along the circumferential direction between any two adjacent first air outlets 1211. The first air outlets 1211 and second air outlets 1212 are staggered. That is, the lower air grille 100b is divided into multiple air outlet positions along the axial direction. In two adjacent air outlet positions, one air outlet position is provided with a first air outlet 1211, and the other air outlet position is provided with two spaced second air outlets 1212 along the circumferential direction. The first air outlets 1211 are directly opposite the gap between the two second air outlets 1212 along the circumferential direction. This layout can realize multi-dimensional and multi-directional air blowing, which helps to reduce air blowing blind spots, reduce local wind disturbance caused by the excessive concentration of air outlets 112, and improve the dispersion and uniformity of air flowing out of the curved air grille 100.

[0056] Along the first direction, the first air vents 1211 of two adjacent lower air vents 100b are staggered, and the second air vents 1212 of two adjacent lower air vents 100b are also staggered. That is, along the first direction, the first air vent 1211 of the preceding lower air vent 100b can be aligned with the second air vent 1212 of the following lower air vent 100b. This staggered arrangement further enhances the dispersion and uniformity of the airflow.

[0057] The area with air outlets 112 on the lower air grille 100b is curved. In some embodiments, the first air outlet 1211 is centrally located, so the air outlet direction of the first air outlet 1211 tends to be vertical. The two second air outlets 1212 are spaced apart circumferentially, so the air outlet directions of the two second air outlets 1212 form a certain angle. Furthermore, the air outlet direction of the first second air outlet 1212 is inclined towards the air outlet position of the first air outlet 1211 of the previous lower air grille 100b, and the air outlet direction of the second second air outlet 1212 is inclined towards the air outlet position of the first air outlet 1211 of the subsequent lower air grille 100b. Since there is a conveyor roller 300 between the two lower air grilles 100b, the air outlet of the second air outlet 1212 can be blown to the area corresponding to the conveyor roller 300, which is conducive to the uniform distribution of airflow and avoids excessive concentration of airflow in a local area or the formation of blind spots.

[0058] Similar to the lower air grating 100b, the upper air grating 100a can also adopt the curved air grating 100 as described in the first aspect. Along the first direction, the first air vents 1211 of two adjacent upper air gratings 100a are staggered, and the second air vents 1212 of two adjacent upper air gratings 100a are also staggered. That is, along the first direction, the first air vent 1211 of the preceding upper air grating 100a can be aligned with the second air vent 1212 of the following upper air grating 100a; this staggered arrangement further enhances the dispersion and uniformity of the airflow.

[0059] Furthermore, both the upper air grating 100a and the lower air grating 100b can be curved air gratings 100 as described in the first aspect. In this case, the upper air grating 100a and the lower air grating 100b are aligned in the vertical direction, and the first air hole 1211 of the upper air grating 100a is arranged opposite to the first air hole 1211 of the lower air grating 100b, and the second air hole 1212 of the upper air grating 100a is arranged opposite to the second air hole 1212 of the lower air grating 100b.

[0060] The arrangement of the upper windshield 100a and lower windshield 100b described above is only one embodiment of this application, and this application does not limit it.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the conveyor roller 300 includes a flexible shaft 310 and multiple drive wheels 320, which are axially spaced and sleeved around the flexible shaft 310. The drive wheels 320 are made of heat-insulating material. During the bending and forming process of tempered glass, the conveyor roller 300 is responsible for conveying the glass sheet from the heating zone to the cooling zone. The flexible shaft 310 provides the necessary support and transmission, while the drive wheels 320 directly contact the glass sheet, ensuring smooth and uniform conveying.

[0062] In the process of bending tempered glass, the glass sheet undergoes two stages: heating and cooling. The heating stage softens the glass, making it easier to shape; while the cooling stage solidifies the glass, forming the desired curved shape. During this process, the uniformity of heat dissipation on the lower surface of the glass has a significant impact on the stress distribution and stress spot quality of the final product. Because the drive wheel 320 is made of heat-insulating material, it does not transfer excessive heat when in contact with the glass sheet, thus avoiding uneven heat dissipation on the lower surface of the glass due to heat conduction. This helps ensure a uniform stress distribution during the cooling process, improving the stress uniformity of physically curved tempered glass.

[0063] Specifically, the transmission wheel 320 can be made of high-temperature resistant ceramic material. The transmission wheel 320 can also be made of fiber insulation material, aerogel insulation material, etc., and this application does not limit its use in this regard.

[0064] The conveyor roller 300 also includes a support base 330, and the flexible shaft 310 is rotatably connected to the support base 330. The support base 330 can also be made of heat-insulating material.

[0065] Based on the above embodiment, the drive wheels 320 of two adjacent conveying rollers 300 along the first direction are staggered. The staggered drive wheels 320 can better distribute the stress points of the glass plate during conveying, reducing instability caused by excessive stress at a single point. This helps maintain the stability of the glass plate during conveying, reducing quality problems caused by shaking or bouncing. It also helps to further improve the heat dissipation uniformity of the lower surface of the glass, reduce the formation of stress spots, and improve the stress uniformity of physically curved tempered glass.

[0066] To accommodate the shape requirements of curved glass, the tempered glass bending forming equipment also includes an adjustment mechanism (not shown). The upper air grate 100a, lower air grate 100b, and conveyor roller 300 all have multiple connection points with the adjustment mechanism. The adjustment mechanism is used to adjust the height of each connection point, allowing the conveyor roller 300 to form a shape that conforms to the curved glass's shape requirements. During the processing of curved tempered glass, the flexible shaft 310 needs to undergo a certain degree of deformation to adapt to the curved shape of the glass, ensuring close contact between the transmission wheel 320 and the glass, thereby providing smooth and accurate glass conveying. The upper air grate 100a and lower air grate 100b also need to undergo a certain degree of deformation so that the air outlet 112 of the curved air grate 100 can always maintain a certain distance and angle from the glass surface, allowing the blowing airflow to evenly cover the entire glass surface.

[0067] It should be noted that the adjustment mechanism can be a screw lifting mechanism, linkage adjustment mechanism, worm gear adjustment mechanism, etc., which are commonly used in the field, and this application will not describe them in detail.

[0068] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
