Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass production technology, and in particular to a swingable air grating device and glass production equipment. Background Technology
[0002] In the process of tempering and quenching curved glass forming, after the flat glass is heated to a preset temperature in the heating furnace, it is conveyed to the forming tempering and quenching air grid. In the traditional curved glass quenching air grid, the quenching air grid maintains a static position relative to the glass conveying rollers during the quenching process. The air grid has air outlet holes arranged on it. During the quenching process, cold air is blown out from the air outlet holes of the air grid and blown onto the glass surface. During the rapid cooling process, a stress layer is formed on the surface of the glass, completing the tempering process.
[0003] In the related technology, the air vents of the air vents in the air vent structure are fixed. Therefore, during the glass quenching process, the fixed position of the air vents will leave traces of the air blowing quenching on the glass surface corresponding to each air vent position. These traces are commonly known as quenching "air spots". These air spots seriously affect the optical quality and visual effect of the glass surface. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its problem is:
[0006] A swingable air vent device, comprising,

[0008] As an optional implementation, the drive cylinder includes a cylinder body and a drive rod, the cylinder body is mounted on the air grille bracket, and the drive rod is connected to the air knife;
[0009] The swing drive assembly further includes a first support and guide mechanism, which is used to guide the air knife to move along the swing direction.
[0010] As an optional implementation, the swing drive assembly further includes a second support guide mechanism, which is disposed on both sides of the air knife in the swing direction, along with the first support guide mechanism. Both the first support guide mechanism and the second support guide mechanism are used to guide the air knife to move along the swing direction.
[0011] As an optional implementation, the first support and guide mechanism includes a guide sleeve and a first guide rod. The guide sleeve is installed on the air grille bracket and spaced apart from the cylinder body. The first guide rod is connected to the air blade and spaced apart from the drive rod. The first guide rod is slidably engaged with the guide sleeve.
[0012] As an optional implementation, the second support and guide mechanism includes a guide plate and two second guide rods. The guide plate is connected to the air knife, and the two second guide rods are connected to the air grid bracket and are spaced apart. The two second guide rods slide in cooperation with the guide plate.
[0013] As an optional implementation, the drive cylinder is a drive cylinder; the drive cylinder is used to drive the air knife to reciprocate along the swing direction.
[0014] The air grating unit also includes an air path control mechanism, which includes an air supply pipe, a first air guide pipe, a second air guide pipe, and an electromagnetic reversing valve. The air supply pipe has an air inlet and an air outlet. The air outlet is equipped with an electromagnetic reversing valve. The first air guide pipe and the second air guide pipe are both connected to the electromagnetic reversing valve. The electromagnetic reversing valve is used to control the airflow at the air outlet to flow to the first air guide pipe or the second air guide pipe. The first air guide pipe and the second air guide pipe are both connected to the cylinder body of the drive cylinder.
[0015] As an optional implementation, both the first air guide pipe and the second air guide pipe are equipped with airflow speed control valves.
[0016] As an optional implementation, the swingable air grating device includes a plurality of the air grating units.
[0017] As an optional implementation, the drive cylinder is a drive cylinder; the drive cylinder is used to drive the air knife to reciprocate along the swing direction.
[0018] The air grating unit also includes an air path control mechanism, which includes an air supply pipe, a first air guide pipe, a second air guide pipe, and an electromagnetic reversing valve. The air supply pipe has an air inlet and an air outlet. The air outlet is equipped with an electromagnetic reversing valve.

[0020] In summary, this utility model has the following technical effects:
[0021] 1. During the glass blowing and quenching process, each wind grid unit changes from a relatively static state to a dynamic reciprocating oscillation. During the blowing and quenching process, the wind spots blown onto the glass surface change from point-like to line-like. Moreover, during air cooling, the air outlet surface formed by continuous air outlet points is used for quenching, making the glass surface more uniformly cooled by air, thereby eliminating wind spots on the surface of curved tempered glass and improving the optical quality of the glass surface.
[0022] 2. Since the air grid unit is used to drive the air blade along the swing drive component, it is driven by the drive cylinder and can directly output rotational torque. There is no need for additional gears, connecting rods or other transmission mechanisms to change the motion form. This reduces the accuracy difference caused by the setting of the transmission structure and the air grid swing control accuracy is higher. Attached Figure Description

[0036] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.
[0037] Example 1,
[0038] See Figures 1-5 This utility model discloses a swingable air grating device 100, including an air grating unit 1, which includes an air grating bracket 10, an air blade 20, and a swing drive assembly. The air blade 20 is mounted on the air grating bracket 10 and can swing along the swing direction D. Multiple air blowing holes 21 are provided on the air blade 20. Furthermore, the swing drive assembly includes a drive cylinder 30, which can drive the air blade 20 to swing relative to the air grating bracket 10 along the swing direction.
[0039] Based on this structure, when using the swingable air grid device 100 of this utility model, the air grid device 100 can be applied to glass production equipment for the quenching and tempering of glass 2.
[0040] In glass production equipment, air grid devices 100 can be installed above and below the conveying component. The conveying component can convey glass 2 along the conveying direction. In related technologies, the conveying component conveys glass 2 along the length direction of glass 2, while the swing direction of the air knife 20 is the width direction of glass 2; or, the conveying component conveys glass 2 along the width direction of the conveying component, and the corresponding swing direction of the air knife 20 can be the length direction of glass 2.
[0041] In this embodiment, the swing direction of glass 2 is taken as the width direction of glass 2, and the conveying direction of glass 2 is taken as the length direction of glass 2.
[0042] Based on this structure, the air grid unit 1 set above and below the conveying component can swing along the width direction of the glass 2 above the conveying component, and can blow air up and down on the glass 2 located on the conveying component. The upper air grid unit 1 can guide the airflow to blow back and forth along the width direction of the glass 2 above the glass 2 through the air blowing hole 21 of the air knife. Similarly, the lower air grid unit 1 can guide the airflow to blow back and forth along the width direction of the glass 2 below the glass 2 through the air blowing hole 21 of the air knife.
[0043] Simultaneously, under the conveying action of the conveying assembly, the glass 2 can oscillate back and forth along its length. Multiple upper air grating units 1 form an air outlet surface along the upper length direction of the glass 2, and multiple lower air grating units 1 form an air outlet surface along the lower length direction of the glass 2. Combined with the oscillation of the glass 2 along its length, this creates multiple consecutive air outlet points along the length of the glass 2. Simultaneously, the air grating units 1 oscillate back and forth along the width direction of the glass 2, thus creating an air outlet surface along the width direction of the glass 2, resulting in multiple consecutive air outlet points along the width direction of the glass 2. The combination of two continuous actions along the length direction allows multiple continuous cooling points to be formed on both the upper and lower surfaces of glass 2. That is, each wind grid unit 1 changes from a relatively static state to a dynamic reciprocating oscillation during the air blowing and quenching process of glass 2. The wind spots blown onto the surface of glass 2 during the air blowing and quenching process change from point-like to line-like. Moreover, during air cooling, the air outlet surface formed by the continuous air outlet points is used for quenching, making the surface of glass 2 more uniformly cooled by air, thereby eliminating wind spots on the surface of curved tempered glass 2 and improving the optical quality of the surface of glass 2.
[0044] It should also be noted that since the wind grid unit 1 is used to drive the wind knife 20 along the swing drive assembly, the drive cylinder 30 is used for driving, such as a hydraulic cylinder or a pneumatic cylinder, which can directly output rotational torque without the need for additional gears, connecting rods or other transmission mechanisms to change the motion form. This reduces the accuracy difference caused by the setting of the transmission structure, and the wind grid swing control accuracy is higher.
[0045] Furthermore, since the drive cylinder 30 is used to drive the swing of the air knife 20, if the air knife 20 experiences a hard impact during its swing, resulting in unstable wind speed, it will also affect the unstable airflow of the air knife 20 and the optical quality of the glass 2 surface. However, since the drive cylinder 30 is driven by a fluid medium (hydraulic oil or compressed air), the fluid medium has a certain buffering capacity, which can effectively reduce the hard impact during the swing of the air knife 20. This improves the swing stability of the air knife 20, thereby stabilizing the wind speed and reducing the impact of unstable wind speed on the cooling of the glass 2.
[0046] As an optional implementation, the drive cylinder 30 includes a cylinder body 31 and a drive rod 32. The cylinder body 31 is mounted on the air grille bracket 10, and the drive rod 32 is connected to the air knife 20. When the air knife 20 is oscillating, the drive rod 32 can extend or retract to drive the air knife 20 to oscillate back and forth.
[0047] Since the air knife 20 needs to swing stably during the swing process, so that the wind speed is relatively stable during the swing process, the swing drive assembly also includes a first support guide mechanism 40. The first support guide mechanism 40 is used to guide the air knife 20 to move along the swing direction. The first support guide mechanism 40 guides the air knife 20 to swing stably in the swing direction. That is, when swinging in the width direction of the glass 2, the blowing point of the air knife 20 will not deviate significantly from the swing motion line. Therefore, the swing blowing point in the width direction of the glass 2 is relatively consistent during the swing process, which makes it easier to eliminate wind spots on the surface of the curved tempered glass 2.
[0048] Similarly, the aforementioned swing drive assembly also includes a second support guide mechanism 50. The second support guide mechanism 50 and the first support guide mechanism 40 are respectively disposed on both sides of the air knife 20 in the swing direction. Both the first support guide mechanism 40 and the second support guide mechanism 50 are used to guide the air knife 20 to move in the swing direction. In this way, the first support guide mechanism 40 and the second support guide mechanism 50 can guide the air knife 20 on both sides of the swing direction, making the swing process more dynamic and the swing line formed by the swing direction less prone to deviation.
[0049] As an optional implementation, the first support and guide mechanism 40 includes a guide sleeve 41 and a first guide rod 42. The guide sleeve 41 is installed on the air grille bracket 10, and the guide sleeve 41 and the cylinder 31 are spaced apart on the air grille bracket 10. The first guide rod 42 is connected to the air knife 20 and spaced apart from the drive rod 32. The first guide rod 42 is slidably engaged with the guide sleeve 41, and the first guide rod 42 and the drive rod 32 can be arranged in parallel. When the drive rod 32 of the drive cylinder 30 guides the air knife 20 to swing, the first guide rod 42 can slide relative to the guide sleeve 41 in a direction parallel to the drive rod 32, thus guiding the stable swing of the air knife 20.
[0050] As an optional implementation, the second support and guide mechanism 50 includes a guide plate 51 and two second guide rods 52. The guide plate 51 is connected to the air knife 20, and the two second guide rods 52 are connected to the air grid bracket 10 and are spaced apart. The two second guide rods 52 are slidably engaged with the guide plate 51. The two second guide rods 52 can be arranged vertically parallel to each other and remain parallel to the swing direction. When the drive rod 32 drives the air knife 20 to move, the two second guide rods 52 can slide relative to the guide plate 51, thereby realizing the swing guidance of the air knife 20.
[0051] As an optional implementation, the drive cylinder 30 is a drive cylinder; the drive cylinder is used to drive the air knife 20 to swing back and forth in the swing direction, so that the piston rod of the drive cylinder can be connected to the air knife 20, and the air knife 20 can be driven to swing back and forth by extending or retracting the piston rod of the drive cylinder.
[0052] Specifically, see Figure 4 as well as Figure 5 The aforementioned air grille unit 1 also includes an air path control mechanism 70, which includes an air supply pipe 71, a first air guide pipe 73, a second air guide pipe 74, and an electromagnetic reversing valve 72. Specifically, the air supply pipe 71 has an air inlet end and an air outlet end. The air inlet end is connected to an air supply device, and the air outlet end is equipped with an electromagnetic reversing valve 72. Both the first air guide pipe 73 and the second air guide pipe 74 are connected to the electromagnetic reversing valve 72. The electromagnetic reversing valve 72 can control the airflow at the air outlet end to flow to the first air guide pipe 73 or the second air guide pipe 74. Both the first air guide pipe 73 and the second air guide pipe 74 are connected to the cylinder body 31 of the drive cylinder.
[0053] Specifically, the cylinder body 31 of the driving cylinder is provided with two air inlets. The first air inlet pipe 73 is connected to one of the air inlets, and the second air inlet pipe 74 is connected to the other air inlet. After the gas is introduced into the cylinder body 31 of the driving cylinder through the first air inlet pipe 73, the piston rod can be driven to extend. At this time, the air inlet connected to the second air inlet pipe 74 can guide the internal gas to be gradually discharged when the piston rod moves, so that the piston rod can extend stably and guide the air knife 20 to swing in one direction.
[0054] After the gas is introduced into the cylinder body 31 of the drive cylinder through the second air guide pipe 74, the piston rod can be driven to retract. At this time, the air guide port connected to the first air guide pipe 73 can guide the internal gas to be gradually discharged when the piston rod moves, so that the piston rod can retract stably and guide the air knife 20 to swing in another direction.
[0055] That is, the solenoid reversing valve 72 can switch the air path to be introduced through the first air guide pipe 73 or the second air guide pipe 74, thereby realizing the control of the reciprocating swing of the air knife 20.
[0056] As an optional implementation, both the first air guide pipe 73 and the second air guide pipe 74 are equipped with airflow speed control valves 75. Since the first air guide pipe 73 and the second air guide pipe 74 can be used to control the extension or retraction of the piston rod of the drive cylinder, the airflow speed control valve 75 is provided on the first air guide pipe 73. The airflow speed control valve 75 can control the gas flow rate in the first air guide pipe 73, thereby controlling the airflow speed entering the cylinder body 31 from the first air guide pipe 73, thereby adjusting the extension speed of the piston rod of the drive cylinder.
[0057] Similarly, an airflow speed control valve 75 is installed on the second air pipe 74. The airflow speed control valve 75 can control the gas flow rate in the second air pipe 74, thereby controlling the airflow speed entering the cylinder 31 from the second air pipe 74, and thus adjusting the piston rod extension speed of the drive cylinder.
[0058] Since both the first air guide pipe 73 and the second air guide pipe 74 are equipped with airflow speed regulating valves 75 for adjusting airflow speed, the extension speed and retraction speed of the piston rod of the drive cylinder can be controlled independently. Thus, the extension speed and retraction speed of the piston of the drive cylinder can be adjusted to be different or the same, depending on the actual needs.
[0059] Of course, in some other embodiments, an airflow speed regulating valve 75 can be installed at the air inlet end of the air supply pipe 71. In this way, the gas flow rate can be uniformly controlled at the air inlet position of the air supply pipe 71, and the extension speed and retraction speed of the piston rod can be uniformly adjusted.
[0060] Example 2,
[0061] See Figure 3 , Figure 4 as well as Figure 5 Unlike Embodiment 1 above, as an optional implementation, the swingable air grating device 100 includes a plurality of air grating units 1. The air grating units of the air grating device are used in groups, and the number of air grating units constituting the air grating device is determined by the specifications of the glass production equipment.
[0062] As an optional implementation, the drive cylinder 30 is a drive cylinder; the drive cylinder is used to drive the air knife 20 to swing back and forth in the swing direction, so that the piston rod of the drive cylinder can be connected to the air knife 20, and the air knife 20 can be driven to swing back and forth by extending or retracting the piston rod of the drive cylinder.
[0063] Specifically, see Figure 4 as well as Figure 5 The aforementioned air grille unit 1 also includes an air path control mechanism 70, which includes an air supply pipe 71, a first air guide pipe 73, a second air guide pipe 74, and an electromagnetic reversing valve 72. Specifically, the air supply pipe 71 has an air inlet end and an air outlet end. The air inlet end is connected to an air supply device, and the air outlet end is equipped with an electromagnetic reversing valve 72. Both the first air guide pipe 73 and the second air guide pipe 74 are connected to the electromagnetic reversing valve 72. The electromagnetic reversing valve 72 can control the airflow at the air outlet end to flow to the first air guide pipe 73 or the second air guide pipe 74. Both the first air guide pipe 73 and the second air guide pipe 74 are connected to the cylinder body 31 of the drive cylinder.
[0064] Specifically, the cylinder body 31 of the driving cylinder is provided with two air inlets. The first air inlet pipe 73 is connected to one of the air inlets, and the second air inlet pipe 74 is connected to the other air inlet. After the gas is introduced into the cylinder body 31 of the driving cylinder through the first air inlet pipe 73, the piston rod can be driven to extend. At this time, the air inlet connected to the second air inlet pipe 74 can guide the internal gas to be gradually discharged when the piston rod moves, so that the piston rod can extend stably and guide the air knife 20 to swing in one direction.
[0065] After the gas is introduced into the cylinder body 31 of the drive cylinder through the second air guide pipe 74, the piston rod can be driven to retract. At this time, the air guide port connected to the first air guide pipe 73 can guide the internal gas to be gradually discharged when the piston rod moves, so that the piston rod can retract stably and guide the air knife 20 to swing in another direction.
[0066] That is, the solenoid reversing valve 72 can switch the air path to be introduced through the first air guide pipe 73 or the second air guide pipe 74, thereby realizing the control of the reciprocating swing of the air knife 20.
[0067] Unlike Embodiment 2, this embodiment has multiple sets of air grille units 1, so it is necessary to supply air to the drive cylinders of multiple sets of air grille units 1 to drive the air blades 20 of the corresponding air grille units 1 to swing.
[0068] See Figure 4 In the relevant implementation structure, the first air guide pipe 73 in each air grid unit 1, which is connected to the air guide port of the cylinder, is connected to the first branch pipe 76, and the second air guide pipe 74, which is connected to the other air guide port of the cylinder, is connected to the second branch pipe 77. That is, the first air guide pipe 73 is connected to the electromagnetic reversing valve 72 through the first branch pipe 76, and the second air guide pipe 74 is connected to the electromagnetic reversing valve 72 through the second branch pipe 77. In this way, the airflow can be guided into the first branch pipe 76 or the second branch pipe 77 through the air supply pipe 71 to realize the reciprocating swing control of the air knife 20 of multiple air grid units 1.
[0069] Based on this structure, airflow speed control valves 75 can be installed on both the first branch pipe 76 and the second branch pipe 77 to control the swing speed of the wind grid unit 1 in a unified manner.
[0070] Alternatively, an airflow speed control valve 75 can be installed on the first air duct 73 and the second air duct 74 of each group of air grid units 1 for individual control.
[0071] See Figure 5In the relevant implementation structure, each air grille unit 1 is separately equipped with a first air guide pipe 73, a second air guide pipe 74, and an electromagnetic reversing valve 72. The air supply pipe 71 is equipped with multiple branch pipes, each of which serves as a separate air inlet pipe and is connected to the electromagnetic reversing valve 72 of the corresponding air grille unit 1. In this way, each air grille unit 1 can be oscillated and controlled individually.
[0072] Example 3,
[0073] See Figures 1-6 Unlike Embodiments 1 and 2, this embodiment provides a glass production equipment, including the swingable air grid device 100 and the conveying roller assembly as in Embodiments 1 and 2. The conveying roller assembly includes multiple conveying rollers 3, which form a conveying surface and can convey glass 2 along the conveying direction; the swinging direction is perpendicular to the conveying direction on the plane of glass 2.
[0074] In glass production equipment, air grid devices 100 can be installed above and below the conveying component. In this embodiment, the air grid device 100 includes multiple air grid units 1, which are distributed in the conveying direction of the conveying component. The conveying component can convey glass 2 along the conveying direction. In related technologies, the conveying component conveys glass 2 along the length direction of glass 2, while the swing direction of the air knife 20 is the width direction of glass 2. Alternatively, the conveying component conveys glass 2 along the width direction of the conveying component, and the corresponding swing direction of the air knife 20 can be the length direction of glass 2.
[0075] In this embodiment, the swing direction of glass 2 is taken as the width direction of glass 2, and the conveying direction of glass 2 is taken as the length direction of glass 2.
[0076] Based on this structure, the air grid unit 1 set above and below the conveying component can swing along the width direction of the glass 2 above the conveying component, and can blow air up and down on the glass 2 located on the conveying component. The upper air grid unit 1 can guide the airflow to blow back and forth along the width direction of the glass 2 above the glass 2. Similarly, the lower air grid unit 1 can guide the airflow to blow back and forth along the width direction of the glass 2 below the glass 2.
[0077] Simultaneously, under the conveying action of the conveying assembly, the glass 2 can oscillate back and forth along its length. Multiple upper air grating units 1 form an air outlet surface along the upper length direction of the glass 2, and multiple lower air grating units 1 form an air outlet surface along the lower length direction of the glass 2. Combined with the oscillation of the glass 2 along its length, this creates multiple consecutive air outlet points along the length of the glass 2. Simultaneously, the air grating units 1 oscillate back and forth along the width direction of the glass 2, thus creating an air outlet surface along the width direction of the glass 2, resulting in multiple consecutive air outlet points along the width direction of the glass 2. The combination of two continuous actions along the length direction at the air outlet point allows multiple continuous cooling points to be formed on both the upper and lower surfaces of glass 2. That is, each wind grid unit 1 changes from a relatively static state to a dynamic reciprocating oscillation during the air blowing and quenching process of glass 2. The wind spots blown onto the surface of glass 2 during the air blowing and quenching process change from point-like to line-like. Moreover, the air outlet surface formed by the continuous air outlet points is used for quenching during air cooling, making the surface of glass 2 more uniformly cooled by air, thereby eliminating wind spots on the surface of curved tempered glass 2 and improving the optical quality of the surface of glass 2.
[0078] It should also be noted that since the wind grid unit 1 is used to drive the wind knife 20 along the swing drive assembly, the drive cylinder 30 is used for driving, such as a hydraulic cylinder or a pneumatic cylinder, which can directly output rotational torque without the need for additional gears, connecting rods or other transmission mechanisms to change the motion form. This reduces the accuracy difference caused by the setting of the transmission structure, and the wind grid swing control accuracy is higher.
[0079] Furthermore, since the drive cylinder 30 is used to drive the swing of the air knife 20, if the air knife 20 experiences a hard impact during its swing, resulting in unstable wind speed, it will also affect the unstable airflow of the air knife 20 and the optical quality of the glass 2 surface. However, since the drive cylinder 30 is driven by a fluid medium (hydraulic oil or compressed air), the fluid medium has a certain buffering capacity, which can effectively reduce the hard impact during the swing of the air knife 20. This improves the swing stability of the air knife 20, thereby stabilizing the wind speed and reducing the impact of unstable wind speed on the cooling of the glass 2.
[0080] Of course, in some implementation structures, the glass production equipment is used for curved glass forming. In this case, the conveying components of the glass production equipment can be curved under the drive of the arc-changing derrick. In order to make sure that the blowing surface of the air grid device is consistent with the curved surface of the curved glass, the air grid bracket of the air grid unit of the air grid device can be connected to the arc-changing component 60 of the arc-changing derrick. In this way, when the curved glass is formed, the multiple air grid units of the air grid device can be arc-changed synchronously with the curved conveying components.
[0081] It should be noted that the variable arc gantry structure in the glass production equipment used for curved glass production requires existing technology and is not part of the technical content to be protected in this application, so it will not be described in detail here.
[0082] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
