Physical tempering is a widely used method for producing tempered glass. The glass is placed in a heating furnace and heated to a temperature close to the softening temperature of the glass. Then it is taken out of the furnace and air is blown to both sides of the glass for rapid cooling. Therefore, the glass needs to pass through the heating furnace and cooling module once before it can be processed and formed.

DETAILED DESCRIPTION

[0040] Combine the following Figures 1 to 22 , describes a tempered glass production system that can improve the quality of the embodiment of the present invention, such as Figure 1 As shown, it includes a loading platform 1, a heating furnace 2, a cooling air grid module 3, a lowering platform 4, a conveying roller 5 and an air supply module 6, wherein the conveying roller 5 sequentially passes through the loading platform 1, the heating furnace 2, the cooling air grid module 3 and the lowering platform 4; Figure 5As shown, the cooling air grille module 3 includes an upper air grille 31, a lower air grille 32 and a first lifting assembly 34, the conveying roller 5 is arranged between the upper air grille 31 and the lower air grille 32, and the first lifting assembly 34 is used to drive the upper air grille 31 and the lower air grille 32 to move simultaneously in a direction close to the conveying roller 5 or simultaneously in a direction away from the conveying roller 5; specifically, the glass heated at a high temperature by the heating furnace 2 needs to be cooled after being taken out of the furnace, and the thicker the glass, the slower the cooling speed, because the cooling speed is too fast, which will cause the glass to burst and cause quality accidents. Therefore, it is necessary to adjust the wind pressure of the cooling air according to the thickness of the glass to avoid the occurrence of quality accidents. When processing glass of different thicknesses, the distance between the upper air grille 31 and the lower air grille 32 and the conveying roller 5 is adjusted by the first lifting assembly 34, and the distance between the upper air grille 31 and the lower air grille 32 and the glass to be processed is adjusted to achieve the purpose of adjusting the wind pressure of the cooling wind blown by the upper air grille 31 and the lower air grille 32 to the surface of the glass to be processed, so that the wind pressure is suitable for the glass to be processed, thereby improving the quality of the finished glass. When processing glass of smaller thickness, the distance between the upper air grille 31 and the lower air grille 32 and the conveying roller 5 can be reduced to increase the wind pressure and speed up the cooling speed; when processing glass of larger thickness, the distance between the upper air grille 31 and the lower air grille 32 and the conveying roller 5 can be increased to reduce the wind pressure and avoid the glass from bursting due to excessive cooling speed. In addition, by adjusting the distance between the upper air grille 31 and the lower air grille 32 and the conveying roller 5, the distance between the upper air grille 31 and the lower air grille 32 can be made more consistent with the thickness of the glass to be processed, so that the glass to be processed can pass through the cooling air grille module 3 smoothly. Fig.11 As shown, the air supply module 6 includes an air collecting box 61, a single fan assembly 62 and a series fan assembly 63. The single fan assembly 62 is a single fan, and the series fan assembly 63 is composed of multiple independent fans 631 connected in series; specifically, the air outlet of the single fan assembly 62 is the air outlet of the fan, and the air outlets of multiple independent fans 631 connected in series are the air outlets of the series fan assembly 63. Fig.12 , 13As shown in Figure 15, the air collecting box 61 includes a box body 611, a first air inlet pipe 612, a second air inlet pipe 613 and an air outlet pipe 614. A first air collecting chamber 6111 and a second air collecting chamber 6112 are provided in the box body 611. A gate valve 65 is provided between the first air collecting chamber 6111 and the second air collecting chamber 6112. The opening and closing of the gate valve 65 controls the connection or closing of the first air collecting chamber 6111 and the second air collecting chamber 6112. The rear end of the first air collecting chamber 6111 is connected to the first air inlet pipe 612 through the first air inlet pipe 613. The air outlet of the series fan assembly 63 is connected, and the front end of the first air collecting chamber 6111 is connected to the air inlet 311 of the upper wind grille 31 and / or the air inlet 311 of the lower wind grille 32 through the air outlet pipe 614; the rear end of the second air collecting chamber 6112 is connected to the air outlet of the single fan assembly 62 through the second air inlet pipe 613, and the front end of the second air collecting chamber 6112 is connected to the air inlet 311 of the upper wind grille 31 and / or the air inlet 311 of the lower wind grille 32 through the air outlet pipe 614. A first air collecting chamber 6111 and a second air collecting chamber 6112 are provided. The series fan assembly 63 inputs the first cooling air into the first air collecting chamber 6111 through the first air inlet pipe 612, and the single fan assembly 62 inputs the second cooling air into the second air collecting chamber 6112 through the second air inlet pipe 613. Since the single fan assembly 62 has only one fan, and the series fan assembly 63 has multiple independent fans 631 connected in series, the wind pressure of the first cooling air is higher than the wind pressure of the second cooling air. A gate valve 65 is installed between the first air collecting chamber 6111 and the second air collecting chamber 6112. According to the thickness of the glass to be cooled, the independent fan 631 connected to the first air collecting chamber 6111 can be opened or closed, or the gate valve 65 can be opened or closed, so that the first air collecting chamber 6111 and the second air collecting chamber 6112 obtain suitable wind pressure, so that the wind pressure of the cooling air blown out by the upper air grille 31 and the lower air grille 32 is suitable for the glass to be processed, thereby improving the quality of the finished glass.

[0041] For example, when it is necessary to cool tempered glass with a smaller thickness, both the single fan assembly 62 and the series fan assembly 63 are turned on, the wind pressure input to the first air collecting chamber 6111 is higher, and the wind pressure input to the second air collecting chamber 6112 is lower. When the gate valve 65 is closed, a cooling section and a passing section will be formed in the cooling air grid module 3, wherein the cooling section is close to the heating furnace 2, and the passing section is far away from the heating furnace 2. The second air collecting chamber 6112 and the second group of air outlet pipes 614 output cooling air with low wind pressure to the cooling section with higher glass temperature, so that the glass is pre-cooled first, and then when the glass passes through the passing section, the first air collecting chamber 6111 and the first group of air outlet pipes 614 output cooling air with high wind pressure in the passing section to quickly cool the glass, thereby improving production efficiency; conversely, when it is necessary to cool thicker tempered glass, the series fan assembly 63 with high wind pressure connected to the first air collecting chamber 6111 can be closed, or the wind pressure at the air outlet of the series fan assembly 63 can be adjusted by the rotating gate 64 to reduce the wind pressure at the air outlet of the series fan assembly 63, and then the gate can be opened. The plate valve 65 is opened, and the single fan assembly 62 with lower wind pressure connected to the second air collecting chamber 6112 is opened, and the wind in the first air collecting chamber 6111 is mixed with the wind in the second air collecting chamber 6112 through the gate valve 65. The wind pressures of the first air collecting chamber 6111 and the second air collecting chamber 6112 are the same, and the wind pressures are both relatively low, so that the wind pressure of the cooling wind blown out by the upper wind grid 31 and the lower wind grid 32 is uniform and the wind pressure is relatively low, allowing the glass to pass through the cooling section and the passing section at a relatively low speed, and the glass can be continuously and evenly cooled in the cooling section and the passing section, which can avoid the glass from bursting due to excessively rapid cooling, thereby avoiding the occurrence of quality accidents and further ensuring the quality of the output glass.

[0042] In some embodiments, such as Figure 5 and 9 As shown, the first lifting assembly 34 includes a universal joint 341, a first tie rod 342 and a second tie rod 343. The first tie rod 342, the universal joint 341 and the second tie rod 343 are connected in sequence. The first tie rod 342 is movably connected to the frame 33 of the cooling air grille module 3, and the second tie rod 343 is fixedly connected to the upper air grille 31 and / or the lower air grille 32. Specifically, the universal joint 341 is also called a universal joint, which is a component for realizing variable angle power transmission. The first tie rod 342 pulls the second tie rod 343 through the universal joint 341, thereby driving the upper air grille 31 or the lower air grille 32 to move. Figure 5-8As shown, the cooling air grille module 3 further includes a guide assembly 35, and the guide assembly 35 includes a guide rail portion 351 and a sliding portion 352. The guide rail portion 351 is fixed to the frame 33, and the sliding portion 352 is fixed to the upper air grille 31 and / or the lower air grille 32. The sliding portion 352 and the guide rail portion 351 are slidably connected; the extension direction of the guide rail portion 351 is parallel to the length direction of the first lifting assembly 34. In this way, when the first lifting assembly 34 drives the upper air grille 31 and / or the lower air grille 32 to perform lifting motion, the sliding direction of the sliding portion 352 in the guide rail portion 351 is consistent with the lifting direction of the upper air grille 31 and / or the lower air grille 32, thereby preventing the sliding portion 352 from getting stuck with the guide rail portion 351. For example, Figure 6 As shown, the guide rail portion 351 may be a guide column, and the sliding portion 352 may be a guide sleeve sleeved on the guide column; for another example, the guide rail portion 351 may be a guide rail, and the sliding portion 352 may be a guide wheel; for another example, Figure 7 As shown, the guide rail portion 351 is a linear guide groove, the sliding portion 352 is a guide wheel, the sliding portion 352 is arranged in the guide rail portion 351 and rolls in the guide rail portion 351, and when the upper air grille 31 and / or the lower air grille 32 are lifted, the sliding portion 352 rolls in the guide rail portion 351, so that the sliding portion 352 and the guide rail portion 351 play a role in guiding the upper air grille 31 and / or the lower air grille 32. For another example, Figure 8 As shown, the guide rail portion 351 is a straight hollow groove, the sliding portion 352 is a guide block, the sliding portion 352 is arranged in the guide rail portion 351 and slides along the length direction of the guide rail portion 351; the side wall of the guide rail portion 351 is provided with an opening, and the opening extends along the length direction of the guide rail portion 351. When the upper air grille 31 and / or the lower air grille 32 is lifted or lowered, the sliding portion 352 slides in the guide rail portion 351, so that the sliding portion 352 and the guide rail portion 351 play a role in guiding the upper air grille 31 and / or the lower air grille 32.

[0043] Alternatively, if Fig.15As shown, the gate valve 65 includes a connecting pipe 651, a first cylinder 652, a second cylinder 653, a first gate plate 654 and a second gate plate 655; the connecting pipe 651 is installed on the partition between the first air collecting chamber 6111 and the second air collecting chamber 6112, and the first air collecting chamber 6111 and the second air collecting chamber 6112 are connected through the connecting pipe 651; the first cylinder 652 and the second cylinder 653 are respectively installed on the front side and the rear side of the connecting pipe 651; the rear end of the first gate plate 654 passes through the front side wall of the connecting pipe 651 and is inserted into the connecting pipe 651, and the front end of the second gate plate 655 passes through the connecting pipe 651 The rear side wall is inserted into the connecting pipe 651, the front end of the first gate plate 654 is transmission-connected to the output end of the first cylinder 652, and the rear end of the second gate plate 655 is transmission-connected to the output end of the second cylinder 653; the first cylinder 652 drives the first gate plate 654 to move forward and backward, and the second cylinder 653 drives the second gate plate 655 to move forward and backward, and the second gate plate 655 and the first gate plate 654 are arranged side by side, and when the first gate plate 654 slides to the maximum stroke, the first gate plate 654 completely covers the connecting pipe 651, and when the second gate plate 655 slides to the maximum stroke, the second gate plate 655 covers a partial area of ​​the connecting pipe 651. The first damper 654 or the second damper 655 can be controlled to move forward and backward by the first cylinder 652 or the second cylinder 653, respectively, so as to control the opening and closing of the damper valve 65, and further control the connection or isolation of the first air collecting chamber 6111 and the second air collecting chamber 6112, so as to adjust the wind pressure output by the first group of air outlet pipes 614 and the second group of air outlet pipes 614. The first air collecting chamber 6111 and the second air collecting chamber 6112 are connected through the gap between the first damper 654 and the second damper 655. As the first damper 654 moves backward and the second damper 655 moves forward, the rear end of the first damper 654 and the front end of the second damper 655 gradually approach each other, and the gap between the rear end of the first damper 654 and the front end of the second damper 655 gradually decreases, and the air flow in the gap also decreases accordingly. When the rear end of the first damper 654 passes forward over the front end of the second damper 655, the channel for air supply is the channel between the first damper 654 and the second damper 655. The gap between the two plate surfaces reaches the maximum stroke when the rear end of the first gate plate 654 passes over the rear side of the connecting duct 651, and the connecting duct 651 is completely isolated and in a completely closed state; in the process from fully open to fully closed, the air supply channel of the connecting duct 651 is gradually reduced; similarly, in the process from fully closed to fully open, the wind flow conveying channel of the connecting duct 651 is also gradually expanded. When the wind pressure of the fan remains unchanged, the wind pressure fluctuation of the airflow conveyed in the connecting duct 651 is small, which can effectively avoid the appearance of air mark defects on the glass surface due to excessive changes in wind pressure.

[0044] Specifically, Fig.15 As shown, the end edge of the rear end of the first gate plate 654 is an arc-shaped protruding toward the center direction of the connecting pipe 651; the end edge of the front end of the second gate plate 655 and the end edge of the rear end of the first gate plate 654 are arc-shaped curved surfaces that are tightly matched with each other; Fig.18 and 19 As shown, when the two gates are close to each other, the ventilation area changes in a curve, and the force of the wind acting on the plate surface changes relatively smoothly, so that the force of the cylinder output changes more smoothly, the control of the first gate 654 and the second gate 655 is more stable, and the cylinder is not easily damaged. The gate valve 65 also includes a plurality of guide plates 656; the guide plates 656 are provided with guide grooves, and the plurality of guide plates 656 are symmetrically installed on the front and rear sides of the partition in groups of two, and the guide plates 656 are distributed on the front and rear sides of the connecting pipe 651; the first gate 654 and the second gate 655 slide along the corresponding guide grooves of the guide plates 656. The upper and lower sides of the first gate 654 or the second gate 655 move left and right in the guide grooves of the corresponding guide plates 656, which can ensure that the first gate 654 and the second gate 655 will not swing up and down when moving left and right, further improving the operation stability of the air collecting box 61 with wind pressure regulation function.

[0045] Preferably, Fig.13 and 14 As shown, the front end of the first air collecting chamber 6111 and the front end of the second air collecting chamber 6112 are both connected to a plurality of air outlet pipes 614 distributed in an array, the first air collecting chamber 6111 supplies air to the passing section of the upper air grille 31 and / or the lower air grille 32 through the air outlet pipe 614, and the second air collecting chamber 6112 supplies air to the cooling section of the upper air grille 31 and / or the lower air grille 32 through the air outlet pipe 614; specifically, the cooling section of the upper air grille 31 and / or the lower air grille 32 is close to the heating furnace 2, and the passing section of the upper air grille 31 and / or the lower air grille 32 is far away from the heating furnace 2. The front end of the first air collecting chamber 6111 and the front end of the second air collecting chamber 6112 are respectively installed with the air outlet adjustment device 66, and the air outlet adjustment device 66 includes a lifting device 662 and a wind shield 661, and the wind shield 661 is in transmission connection with the lifting device 662, and the lifting device 662 drives the wind shield 661 to move up and down, and when moving up and down, the wind shield 661 blocks a row of the air outlet pipes 614 or the area between the upper and lower rows of the air outlet pipes 614. The upper and lower heights of the wind shield 661 can be adjusted by the air outlet adjustment device 66, and a row of the air outlet pipes 614 can be partially or completely covered, or all the air outlet pipes 614 can be left uncovered, so as to achieve the purpose of adjusting the wind pressure and wind speed output by the air outlet pipes 614, and ensure the production quality of tempered glass cooling.

[0046] Specifically, Fig.15 As shown, the box body 611 is also provided with four supporting feet 6113, and the four supporting feet 6113 are respectively installed below the four corners of the box body 611; the bottom surfaces of the four supporting feet 6113 are located in the same plane; the bottom surfaces of the four supporting feet 6113 are located in the same plane, which can make the box body 611 have better installation stability and improve the operation stability of the air collecting box 61 with wind pressure regulation function. The box body 611 is also provided with a bottom plate 6114; the bottom plate 6114 is located below the first air collecting cavity 6111 and the second air collecting cavity 6112, and the distance between the rear bottom edge of the bottom plate 6114 away from the air outlet pipe 614 and the bottom surface of the supporting feet 6113 is greater than the distance between the front bottom edge of the bottom plate 6114 close to the air outlet pipe 614 and the bottom surface of the supporting feet 6113. The air collecting box 61 is installed close to the cooling section and the passing section of the upper air grille 31 and / or the lower air grille 32. The cooling air is blown downward on the surface of the glass. The cooling air that has exchanged heat becomes hot air carrying heat and is then discharged to the rear side of the box body 611 through the bottom of the bottom plate 6114. The bottom plate 6114 is set to be inclined, and the rear bottom edge of the bottom plate 6114 away from the air outlet pipe 614 is higher than the front bottom edge of the bottom plate 6114, which is beneficial to the discharge and diffusion of hot air and the improvement of the glass cooling efficiency.

[0047] Preferably, Figure 4 As shown, a plurality of convection devices 21 are distributed in an array on the top of the heating furnace 2, and the air inlet of the convection device 21 is connected to the air outlet of the heating furnace 2, and the air outlet of the convection device 21 is connected to the air inlet of the heating furnace 2, and the air inlet of the heating furnace 2 is provided with a heating component. Specifically, after the hot air is blown onto the glass, the heat of the hot air is absorbed by the glass, and the temperature of the glass rises. After the heat is absorbed, the temperature of the hot air decreases, and is absorbed by the air inlet of the convection device 21, and then blown out from the air outlet of the convection device 21 to the air inlet of the heating furnace 2. The hot air with reduced temperature passes through the heating component, and is thus reheated and its temperature increases. The convection device 21 improves the utilization rate of the hot air in the heating furnace 2, thereby improving the heating efficiency. The convection device 21 promotes the air circulation in the heating furnace 2 through the operation of the fan, thereby making it easier to control the heating temperature, improve the stability of glass heating, and thus improve the quality of the finished glass products. It is worth noting that, Figure 5 and 10As shown, one end of the air inlet 311 of the upper air grille 31 and / or the air inlet 311 of the lower air grille 32 close to the air outlet 614 is a circular opening, and the other end of the air inlet 311 of the upper air grille 31 and / or the air inlet 311 of the lower air grille 32 away from the air outlet 614 is a rectangular opening, and the cross section of the side wall of the air inlet 311 is a shape that gradually changes from a circular shape to a rectangular shape from the direction close to the air outlet 614 to the direction away from the air outlet 614. In this way, the inner wall of the air inlet 311 of the upper air grille 31 and / or the air inlet 311 of the lower air grille 32 can be made smoother, and the energy consumed when the cooling air passes through the air inlet 311 of the upper air grille 31 and / or the air inlet 311 of the lower air grille 32 is reduced.

[0048] In some embodiments, such as Figure 2 and 3As shown, the upper sheet platform 1 and / or the lower sheet platform 4 is provided with a glass lifting device 11, and the glass lifting device 11 includes a second lifting component 12, a driving connecting rod 13 and a lifting drive mechanism 14, and the second lifting component 12 is arranged between two adjacent roller shafts of the conveying roller 5; a plurality of second lifting components 12 are rotatably connected to the driving connecting rod 13, and the second lifting component 12 includes a crank 121, a cylindrical boss 122, a support platform 123 and a mounting seat 124; the crank 121 includes a straight portion 1211 and a crank arm portion 1212, and the front side and the rear side of the straight portion 1211 are symmetrically integrally formed with a cylindrical boss 122, and the cylindrical boss 122 is rotatably connected to the driving connecting rod 13; in this way, the central axis of the cylindrical boss 122 arranged on the front side of the crank 121 coincides with the central axis of the cylindrical boss 122 arranged on the rear side of the crank 121. The crank arm 1212 is rotatably connected to the support platform 123, and the intersection of the straight portion 1211 and the crank arm 1212 is rotatably connected to the mounting seat 124, and the mounting seat 124 is fixedly mounted on the bottom surface of the upper platform 1 or the lower platform 4; the lifting drive mechanism 14 is connected to the bottom end of the straight portion 1211 of any one of the cranks 121. The glass lifting device 11 is used to lift the glass located on the upper platform 1 and / or the lower platform 4. For the upper platform 1, after placing the glass on the glass lifting device 11, the glass is lowered to the conveying roller 5 by the glass lifting device 11. For the lower platform 4, when the glass is conveyed to the lower platform 4, the glass lifting device 11 lifts the glass, so that it is convenient for the staff to remove the glass. When lifting a glass with a large area, the cylindrical boss 122 is the main force point. Since the cylindrical boss 122 and the crank 121 are integrally formed, the connection firmness between the cylindrical boss 122 and the crank 121 is improved, so that the cylindrical boss 122 will not be crushed due to the heavy weight of the glass. The integrally formed structure of the cylindrical boss 122 and the crank 121 can withstand heavier glass weight, thereby solving the problem that the rotation connection between the crank 121 and the first driving connecting rod 13 is easily damaged when lifting heavy glass, reducing the probability of production accidents, thereby improving production efficiency.

[0049] The lifting drive mechanism 14 drives the crank 121 to rotate counterclockwise with the intersection of the straight portion 1211 and the crank arm portion 1212 as the rotation axis. While the crank arm portion 1212 rotates counterclockwise, the end of the crank arm portion 1212 away from the straight portion 1211 tilts upward, driving the support platform 123 to move upward. While the crank 121 rotates counterclockwise with the intersection of the straight portion 1211 and the crank arm portion 1212 as the rotation axis, the straight portion 1211 of the crank 121 pushes the first drive link 13 to move from left to right through the structure of the rotational connection between the cylindrical boss 122 and the first drive link 13, thereby driving the rest of the second lifting components 12 to move counterclockwise, so that the support platforms 123 corresponding to the rest of the second lifting components 12 all move upward synchronously to lift the glass together. The lifting drive mechanism 14 drives the crank 121 to rotate clockwise with the intersection of the straight portion 1211 and the crank arm 1212 as the rotation axis. While the crank arm 1212 rotates clockwise, the end of the crank arm 1212 away from the straight portion 1211 moves downward, driving the support platform 123 to move downward. While the crank 121 rotates clockwise with the intersection of the straight portion 1211 and the crank arm 1212 as the rotation axis, the straight portion 1211 of the crank 121 pushes the first drive link 13 from right to left through the structure of the rotational connection between the cylindrical boss 122 and the first drive link 13, thereby driving the remaining second lifting components 12 to move clockwise, so that the support platforms 123 corresponding to the remaining second lifting components 12 all move downward synchronously, so that the glass falls to the upper plate 1 or the lower plate 4.

[0050] It is worth noting that if Fig.11 , 16, 17 and 18, the series fan assembly 63 also includes a series air duct 632 and a rotating gate 64, and multiple independent fans 631 are connected in series through the series air duct 632; the side wall of the series air duct 632 is provided with an adjustment opening 6321, and the series air duct 632 is connected to the outside through the adjustment opening 6321; the adjustment opening 6321 is fixedly connected to the rotating gate 64, and the rotating gate 64 includes an adjustment cover 641, a gate The gate seat 642 and the driving mechanism 643 are provided. The gate seat 642 is a cylindrical tube structure. The gate seat 642 is fixedly connected to the tube wall of the series air duct 632. The adjusting cover plate 641 is arranged in the gate seat 642 and the central axis of the adjusting cover plate 641 coincides with the central axis of the gate seat 642; thus, the gate seat 642 can rotate with the central axis of the gate seat 642 as the rotating axis and will not collide with the inner wall of the gate seat 642. A shielding plate assembly 6421 is fixedly connected in the gate seat 642. The shielding plate assembly 6421 is parallel to the adjusting cover plate 641. The sum of the areas of the shielding plate assembly 6421 and the adjusting cover plate 641 is greater than or equal to the cross-sectional area of ​​the gate seat 642; for example, the shielding plate assembly 6421 is a semicircular structure, and the adjusting cover plate 641 is also a semicircular structure. For another example, the shielding plate assembly 6421 is a 120° fan-shaped structure, and the adjustable cover plate 641 is a fan-shaped structure greater than 240°. When the shielding plate assembly 6421 and the adjustable cover plate 641 are staggered from each other, it can be ensured that the surface formed by the shielding plate assembly 6421 and the adjustable cover plate 641 can cover the entire cross-sectional area of ​​the gate seat 642, thereby achieving the purpose of closing the rotating gate 64. The adjusting cover 641 is provided with a first connecting hole 6413, and the central axis of the adjusting cover 641 passes through the first connecting hole 6413; the driving mechanism 643 includes a rotating driving component 6431 and a driving output component 6432, the driving output component 6432 is fixedly connected to the first connecting hole 6413, the rotating shaft of the rotating driving component 6431 is transmission-connected to the driving output component 6432, the rotating driving component 6431 drives the adjusting cover 641 to rotate in the gate seat 642 with its own central axis as the rotating shaft through the driving output component 6432, when the adjusting cover 641 and the shielding plate component 6421 jointly cover the gate seat 642, the rotating gate 64 is closed to close the adjusting opening 6321; when the adjusting cover 641 and the shielding plate component 6421 partially or completely overlap, the rotating gate 64 is opened to open the adjusting opening 6321. Specifically, by adjusting the rotation angle of the adjustment cover 641, the opening of the rotating shutter 64 can be adjusted, thereby adjusting the opening of the adjustment opening 6321 to achieve the purpose of controlling the wind pressure. Fig.16As shown, in this embodiment, the rotation drive component 6431 is a reduction motor. Fig.17 As shown, in another embodiment, the rotation drive component 6431 is a cylinder, and the rotation drive component 6431 drives the u-drive output component 6432 to rotate through a crank arm.

[0051] Preferably, Figure 19-22As shown, the drive output component 6432 includes a screw rod 643B and a screw rod seat 643C, the output part of the rotation drive component 6431 is connected to the screw rod 643B, the screw rod 643B is threadedly connected to the screw rod seat 643C, and the screw rod seat 643C is fixed to the gate seat 642; the central axis of the output part of the rotation drive component 6431, the central axis of the screw rod seat 643C and the center of the first connecting hole 6413 are located in the same straight line, and the screw rod 643B passes through the output part of the rotation drive component 6431 and the screw rod seat 643C in sequence and is fixedly connected to the first connecting hole 6413; the rotation drive component 6431 drives the screw rod 643B to rotate, and the screw rod 643B performs telescopic movement in the screw rod seat 643C along the inward and outward directions of the adjustment opening 6321 while rotating. The rotating drive component 6431 drives the adjusting cover 641 to rotate in the gate seat 642 with its own central axis as the rotating axis through the driving output component 6432. At the same time, the screw rod 643B of the driving output component 6432 can make telescopic movements in the inner and outer directions of the adjusting opening 6321 while rotating, thereby driving the adjusting cover 641 to make telescopic movements in the same direction, and then approach or move away from the baffle assembly 6421. In this way, when the adjusting cover 641 rotates and closes the rotating gate 64 to close the adjusting opening 6321, since the adjusting cover 641 moves close to the baffle assembly 6421, a gap between the adjusting cover 641 and the baffle assembly 6421 is avoided, the air tightness of the rotating gate 64 is improved, so that the adjusting opening 6321 after closing will not leak air, thereby improving the adjustment accuracy of the wind pressure of the air supply module 6, so that the wind flow generated by the air supply module 6 remains stable, and then the wind flow blown to the glass surface by the cooling air grid module 3 remains stable, thereby improving the quality of the finished glass product; when the adjusting cover 641 rotates and opens the rotating gate 64 to open the adjusting opening 6321, the adjusting cover 641 moves in a direction away from the baffle assembly 6421, thereby avoiding friction between the adjusting cover 641 and the baffle assembly 6421, and improving the smoothness of the rotation of the adjusting cover 641. Since the central axis of the output part of the rotary drive assembly 6431, the central axis of the screw seat 643CC and the center of the first connecting hole 6413 are located in the same straight line, the straightness of the screw 643BB can be ensured, thereby ensuring the smoothness of the screw 643B when rotating. In addition, the rotary gate 64 adopts a rotary opening and closing structure, which saves more space than the straight-insertion gate, thereby increasing the application flexibility of the rotary gate 64.

[0052] The specific process of processing glass in the glass tempering system is as follows: first, the glass to be processed is placed on the upper table 1, and the glass to be processed is sent into the heating furnace 2 through the conveying roller 5. The heating furnace 2 heats the glass to be processed. During the heating process, the convection device 21 works to promote the air flow in the heating furnace 2, so as to improve the heating efficiency of the glass; after the glass to be processed is heated to a preset temperature, it is sent into the cooling air grid module 3 through the conveying roller 5. At this time, the air supply module 6 works, and its corresponding independent fan 631 moves to deliver high-pressure air, and blows the high-pressure air to the surface of the glass through the cooling air grid module 3 for cooling. For processing glass of different models and sizes, the opening of the adjustment opening 6321 is adjusted by the rotating gate 64, and the gate valve 65 is adjusted to adjust the wind pressure of the cold air blown to the glass surface; after the glass is cooled by the cooling air grid module 3, it is transported to the lower table 4 through the conveying roller 5 to form a finished tempered glass.
