[0027] At present, when the tempering process is used to produce thin glass in a double-chamber furnace, large folding is likely to occur at the front and rear ends of the glass as it enters the furnace. Excessive folding of the edges of the glass may easily lead to unqualified imaging.
[0028] Therefore, it is urgent to solve the problem of excessive folding position of the edge of tempered glass.
[0029] The utility model provides a wind grille component.
[0030] See also Figure 1 and Figure 2 In one embodiment of the utility model, the wind grille assembly is applied to a glass tempering furnace, the glass tempering furnace has a furnace outlet, and the wind grille assembly includes a wind grille structure 1 and a baffle 2; the wind grille structure 1 is arranged on the outside of the glass tempering furnace and close to the furnace outlet; the wind grille structure 1 includes a plurality of wind blades 11, and the plurality of wind blades 11 are arranged side by side; the baffle 2 is installed on the frame of one or more of the wind blades 11; the baffle 2 is used to partially block or completely block the air outlet of the wind blade 11.
[0031] The technical solution of the utility model is to install a baffle 2 on the wind blade 11 of the wind grille structure 1, and use the baffle 2 to partially or completely block the wind outlet of the wind blade 11, thereby reducing the air outlet volume of the wind blade 11; when the tempered glass passes through the wind grille assembly, it is ensured that the amount of wind blowing on the glass is moderate so as not to cause the glass to be deformed, thereby avoiding the occurrence of glass folding phenomenon.
[0032] In addition, the researchers found through experiments that the wind grille close to the furnace outlet is likely to slightly reduce the temperature at the furnace outlet after long-term blowing. The temperature reduction is likely to cause uneven heating of the glass in the tempering furnace, and also to cause excessive folding of the front and rear ends of the glass. Therefore, after using the baffle 2 to partially or completely block the air outlet of the wind blade 11, it can effectively avoid the temperature at the furnace outlet being too low, thereby avoiding the folding of the front and rear ends of the glass.
[0033] In the embodiments of the present invention, please refer to Figure 1 When the baffle 2 partially blocks the air outlet of the wind knife 11, the baffle 2 covers 60% to 70% of the air outlet area of the wind knife 11. In this way, the air outlet of the wind knife 11 can be reduced to avoid the glass with low rigidity just out of the furnace from bending due to excessive air outlet, and a certain degree of air outlet can be provided to cool the glass as soon as possible.
[0034] In the embodiments of the present invention, please refer to Figure 3 The wind grille assembly also includes a mounting frame 3 in a ring structure; the frame of the mounting frame 3 is connected to the frame of the wind blade 11, and an opening is provided on the top of the mounting frame 3, through which the mounting frame 3 is plugged and matched with the baffle 2.
[0035] In this embodiment, the baffle 2 is plugged into and matched with the mounting frame 3, and the mounting frame 3 fixes the baffle 2 to the frame of the wind blade 11. This fixing method is convenient and efficient to operate, and when it is necessary to replace baffles 2 of different lengths to achieve different degrees of shielding, the baffle 2 can be directly plugged in and pulled out for disassembly and replacement, thereby improving the efficiency of installation and disassembly.
[0036] In the embodiments of the present invention, please refer to Figure 3 The mounting frame 3 includes an upper frame 31 and a lower frame 32. Both the upper frame 31 and the lower frame 32 are open-loop shaped. The open loop direction of the upper frame 31 faces downward, and the open loop direction of the lower frame 32 faces upward. The upper frame 31 is connected to the lower frame 32. The inner ring of the lower frame 32 is provided with a plug-in groove. The lower frame 32 is plug-in-matched with the bottom of the baffle 2 through the plug-in groove. The frame of the lower frame 32 is connected to the frame of the wind knife edge 11. The inner ring of the upper frame 31 is provided with a socket interface connected to the outer ring, and the upper frame 31 is socket-matched with the baffle 2 through the socket interface.
[0037] In this embodiment, the mounting frame 3 includes a split upper frame 31 and a lower frame 32, the lower frame 32 is plugged into the baffle 2 through a plug-in slot to fix the bottom of the baffle 2; the upper frame 31 is then sleeved with the baffle 2 through a sleeve interface to fix the side of the baffle 2. The above-mentioned fixing method is not only easy to operate, but also easy to disassemble and replace, so that the operator can adjust and replace the baffle 2 of different lengths according to actual needs to cover the wind knife 11.
[0038] Among them, as an optional implementation, the frame of the lower frame 32 and the frame of the wind blade 11 can be fixed by welding, and the joint between the lower frame 32 and the upper frame 31 can be fixed by spot welding; and the upper frame 31 can be welded to the frame of the wind blade 11, and can also be not connected to the frame of the wind blade 11. The connection relationship between the upper frame 31 and the wind blade 11 is not limited here.
[0039] In the embodiment of the present utility model, in order to solve the problem that the baffle 2 is difficult to grasp, please refer to Figure 3 The wind grille assembly also includes a handle 4, which is arranged on the top of the baffle 2. In this way, after the handle 4 is provided, the operator can install and remove the baffle 2 by holding the handle 4, thereby effectively reducing the difficulty of applying force.
[0040] In the embodiment of the utility model, based on the above-mentioned implementation mode that the baffle 2 is sleeved with the socket of the upper frame 31 and plugged with the plug slot of the lower frame 32, the freedom of the baffle 2 in the direction away from the plug slot is not restricted, and there is a problem that the baffle 2 is easy to loosen and fall off. To solve the above problem, this embodiment provides two optional implementation modes:
[0041] As an alternative implementation, see Figure 3 and Figure 4 The wind grille assembly further includes a fastener 5, and an opening is provided on the top side of the upper frame 31; the fastener 5 passes through the opening and abuts against the baffle 2. In this way, after the fastener 5 abuts against the baffle 2, the movement of the baffle 2 in the direction away from the plug-in slot is restricted because the fastener 5 provides static friction to the baffle 2, which effectively restricts the freedom of the baffle 2 in all directions, and prevents the baffle 2 from loosening and detaching. Specifically, the fastener 5 can be set as a threaded connector, and the opening can be set as a screw hole, so as to improve the reliability of the abutment effect of the fastener 5 on the baffle 2.
[0042] As another optional embodiment, the wind grille assembly also includes a fastener 5, and an opening is provided on the top side of the upper frame 31; the baffle 2 is provided with a first through hole; the fastener 5 passes through the opening and the first through hole in sequence, and fixes the upper frame 31 and the baffle 2 to the frame of the wind blade 11. In this way, the fastener 5 can directly fix the baffle 2 to the frame of the wind blade 11 to achieve a reliable fastening effect. Specifically, the fastener 5 can be set as a threaded connector, and the frame of the wind blade 11 is provided with a screw hole, so that the baffle 2 is stabilized by the threaded connector; the fastener 5 can also be set as a rivet, and the baffle 2 is riveted to the frame of the wind blade 11 by the rivet, so as to achieve the fastening of the baffle 2. Of course, other connection methods can also be used to fix the baffle 2, which will not be repeated here.
[0043] In the embodiment of the utility model, in order to solve the problem of scattered air blowing from the wind knife 11, the wind knife 11 is in a long strip shape, so that the air outlet of the wind knife 11 is concentrated, blowing air to a specific position of the glass, and improving the blowing cooling effect.
[0044] The utility model also provides a glass tempering furnace, which includes the above-mentioned air grille assembly. The specific structure of the air grille assembly refers to the above-mentioned embodiment. Since the glass tempering furnace adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.
[0045] Before the adoption of the wind grille assembly, when thin plate glass was produced using the existing glass tempering furnace, the front and rear ends of the glass had excessive folding, and the distance between the front and rear ends was about 150 mm; after the adoption of the wind grille assembly, the glass produced using the glass tempering furnace of the utility model had a folding distance of about 40 mm at the front and rear ends, which greatly improved the phenomenon of excessive folding at the front and rear ends of the thin plate glass, and solved the problem of excessive folding at the front and rear ends of the thin plate glass; thereby reducing the amount of waste caused by unqualified molding in the process of producing thin plate glass, improving product quality and yield rate, and reducing production costs.
[0046] In the embodiment of the utility model, in the specific implementation of the glass tempering furnace, the glass tempering furnace also includes a furnace body, a glass conveying device and a plurality of wind grille assemblies; the furnace body has a furnace outlet and a furnace inlet; the glass conveying device is used to convey the glass from the furnace inlet to the outside of the furnace outlet; the wind grille assembly is arranged on the outside of the furnace body and close to the furnace outlet; a part of the wind grille assembly is arranged above the glass conveying device and the wind knife 11 is arranged downward; another part of the wind grille assembly is arranged below the glass conveying device and the wind knife 11 is arranged upward. In this way, the upper and lower surfaces of the glass are cooled respectively by the wind grille assemblies respectively arranged above and below the glass conveying device, so that the glass can be cooled and tempered while it is out of the furnace and transported to the next process.
[0047] As an optional embodiment, for the wind grid assembly located above the glass conveyor, the first wind knife mouth 11 and the second wind knife mouth 11 closest to the furnace outlet can be covered by the baffle 2 to cover 60% to 70% of the air outlet area of the wind knife mouth 11; for the wind grid assembly located below the glass conveyor, the first wind knife mouth 11 closest to the furnace outlet can be completely covered by the baffle 2. In this way, the first wind knife mouth 11 and the second wind knife mouth 11 located above the glass conveyor can provide a certain amount of blowing air to the upper surface of the glass, which can avoid the edge bending and accelerate the cooling speed of the glass; and by making the first wind knife mouth 11 located below the glass conveyor completely blocked by the baffle 2, it is avoided that after the air volume of the first wind knife mouth 11 and the second wind knife mouth 11 above is weakened, the first wind knife mouth 11 below provides too much blowing air, thereby achieving the effect of ensuring the glass yield and rapid cooling.
[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
