Description

Technical Field

[0001] The invention relates to the technical field of glass tempering, in particular to a glass tempering air supply system with reliable wind control. Background Art

[0002] The air supply system includes a fan, an air duct and an air collecting box. After the fan works to form high-pressure cooling, the high-pressure cold air is sent to the air collecting box through the air duct. The air collecting box evenly distributes the high-pressure cold air to its own air outlets, and then blows it to the glass heated by the tempered glass furnace through the wind grid. The thickness of tempered glass for different purposes is different. When cooling the glass, the thicker the glass, the slower the cooling rate. Therefore, the air pressure of the air outlet needs to be adjusted according to the thickness of the glass. In the prior art, the upper limit of the air pressure is usually increased by connecting fans in series, and an air duct damper is set between two fans in series to adjust the air pressure. The existing duct dampers are generally plug-in type dampers, which are arranged perpendicular to the duct. When the duct damper is pulled away from the inside of the duct, the duct damper opens, and when the duct damper is inserted into the inside of the duct, the duct damper closes. However, in this structure, the duct damper opens and closes by moving in a vertical guide rail. When the wind pressure is high, the duct damper will be blown to one side of the guide rail, thereby increasing the friction between the duct damper and the guide rail, reducing the opening and closing speed of the duct damper, thereby reducing the reliability of wind control.

DETAILED DESCRIPTION

[0035] Combine the following Figures 1 to 19, describes an embodiment of the present invention, a glass tempering air supply system with reliable wind control, including an air collecting box C1 and a series air unit C3, the air collecting box C1 includes a box body C11 and an air inlet pipe, the air collecting cavity in the box body C11 and the air outlet of the series air unit C3 are connected through the air inlet pipe; the series air unit C3 includes an independent fan C31, a combined air duct C32 and a rotary gate C4, a plurality of the independent fans C31 are connected in series through the combined air duct C32; a side wall of the combined air duct C32 is provided with an air control port C321, the combined air duct C32 is connected to the outside through the air control port C321; the air control port C321 is fixedly connected to the rotating gate C4; the rotating gate C4 includes a rotating baffle plate unit C41, a plate mounting seat C42 and a driving mechanism C43, the plate mounting seat C42 is a cylindrical tube structure, the plate mounting seat C42 is fixedly connected to the tube wall of the combined air duct C32, the rotating baffle plate unit C41 is arranged in the plate mounting seat C42 and the central axis of the rotating baffle plate unit C41 coincides with the central axis of the plate mounting seat C42; thereby, it can rotate in the plate mounting seat C42 with the central axis of the plate mounting seat C42 as the rotating axis, and will not collide with the inner wall of the plate mounting seat C42. A windshield assembly C421 is fixedly connected to the plate mounting seat C42, and the windshield assembly C421 is parallel to the rotating shielding plate unit C41, and the sum of the areas of the windshield assembly C421 and the rotating shielding plate unit C41 is greater than or equal to the cross-sectional area of ​​the plate mounting seat C42; for example, the windshield assembly C421 is a semicircular structure, and the rotating shielding plate unit C41 is also a semicircular structure. For another example, the windshield assembly C421 is a 120° fan-shaped structure, and the rotating shielding plate unit C41 is a fan-shaped structure greater than 240°. For another example, Fig.10As shown, the wind shield assembly C421 is a U-shaped structure, one side of the arc is fixed to one side of the plate mounting seat C42, and the other side is suspended away from the central axis of the plate mounting seat C42, and the rotating shielding plate unit C41 is a structure complementary to the wind shield assembly C421. When the wind shield assembly C421 and the rotating shielding plate unit C41 are staggered with each other, it can be ensured that the surface formed by the wind shield assembly C421 and the rotating shielding plate unit C41 can cover the cross-sectional area of ​​the entire plate mounting seat C42, thereby achieving the purpose of closing the rotating gate C4. The rotating shielding plate unit C41 is provided with a first mounting through hole C413, and the central axis of the rotating shielding plate unit C41 passes through the first mounting through hole C413; the driving mechanism C43 comprises a cylinder C431, a rocker assembly C432 and a driving output assembly C433, the rocker assembly C432 comprises a first rocker C4321 and a second rocker C4322, the output shaft C4311 of the cylinder C431 is fixedly connected to one end of the first rocker C4321, the other end of the first rocker C4321 is hinged to one end of the second rocker C4322, the other end of the second rocker C4322 is connected to the driving output assembly C433, and the driving output assembly C433 is fixedly connected to the first mounting through hole C413; the cylinder The output shaft C4311 of C431, the first rocker C4321 and the second rocker C4322 are located in the same plane, and the drive output assembly C433 is perpendicular to the second rocker C4322; the cylinder C431 drives the rotating shielding plate unit C41 to rotate in the plate mounting seat C42 with its own central axis as the rotating axis through the rocker assembly C432 and the drive output assembly C433; when the rotating shielding plate unit C41 and the wind shielding plate assembly C421 jointly cover the plate mounting seat C42, the rotating gate C4 is closed, so that the wind control port C321 is closed; when the rotating shielding plate unit 1 and the wind shielding plate assembly 21 partially or completely overlap, the rotating gate C4 is opened, so that the wind control port C321 is opened. Specifically, by adjusting the rotation angle of the rotating shielding plate unit C41, the opening degree of the rotating gate C4 can be adjusted, thereby achieving the purpose of controlling the wind pressure. The first rocker arm C4321 and the second rocker arm C4322 can both be formed by hingedly connecting at least one section of rocker arm, so as to convert the linear force generated by the cylinder C431 into a rotational force and apply the rotational force to the drive output component C433.

[0036] The rotating gate C4 adopts a rotating opening and closing structure. The cylinder C431 drives the rocker assembly C432 to move, thereby driving the drive output assembly C433 to rotate, and then drives the rotating shielding plate unit C41 to rotate with its own central axis in the plate mounting seat C42 to realize the opening and closing of the rotating gate C4, and realize the opening and closing of the wind control port C321. Compared with the plug-in gate, the rotating gate C4 does not need a guide rail to guide the opening and closing. In this way, when the wind pressure is large, the friction between the guide rail will not increase, so the opening and closing speed of the gate can be increased, thereby improving the stability of the air duct adjustment. When working, the air outlet of the series fan unit C3 is connected to the air inlet pipe of the air collecting box C1, and the rotating gate C4 is used to adjust the opening of the wind control port C321, thereby adjusting the wind pressure of the air outlet of the combined air duct C32, thereby achieving the purpose of indirectly controlling the outlet air pressure of the air collecting box C1. When making thin glass, the rotary gate C4 is closed, and all independent fans C31 work at the same time. The previous independent fan C31 blows air into the next independent fan C31, and finally the last independent fan C31 blows air into the air collecting box C1. When multiple fans are used in series, the total output wind pressure is the superposition of the wind pressures of multiple independent fans C31. The wind pressure is increased to speed up the tempering rate, so that the thin glass meets the tempering requirements. When making thick glass, only the independent fan C31 closest to the air inlet pipe needs to be turned on. At this time, the rotary gate C4 is opened, and the wind from the external environment enters the independent fan from the rotary gate C4, thereby achieving the purpose of energy saving. After the cold air blown out by the fan enters the air collecting cavity in the box C11 from the air inlet pipe, the wind pressure is evenly distributed in the air collecting cavity, and then the cold air is blown from the air outlet pipe C14 of the air collecting box C1 to the wind grid, and then blown to the hot glass through the wind grid, thereby cooling the glass.

[0037] In some embodiments, a single air unit C2 is further included; specifically, the single air unit C2 is a single fan, and the air outlet of the single air unit C2 is the air outlet of the fan. The air collecting cavity is divided into a first air collecting cavity C111 and a second air collecting cavity C112. Fig.12 and 15 As shown, a gate valve C5 is provided between the first air collecting chamber C111 and the second air collecting chamber C112, and the opening and closing of the gate valve C5 controls the connection or closing of the first air collecting chamber C111 and the second air collecting chamber C112; the air inlet pipe is divided into a first air inlet pipe C12 and a second air inlet pipe C13, and the first air inlet pipe C12 and the second air inlet pipe C13 are both installed on the rear side of the box body C11, and the front end of the first air inlet pipe C12 is connected to the rear end of the first air collecting chamber C111, and the front end of the second air inlet pipe C13 is connected to the rear end of the second air collecting chamber C112, as shown Fig.11As shown, the rear end of the first air inlet pipe C12 is connected to the air outlet of the series air unit C3, and the rear end of the second air inlet pipe C13 is connected to the air outlet of the single air unit C2. The glass heated at high temperature in the tempered glass furnace needs to be cooled after it comes out of the furnace. The thicker the glass, the slower the cooling speed. If the cooling speed is too fast, the glass will crack 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 quality accidents. Fig.11 , 12 As shown in Figure 13, a first air collecting chamber C111 and a second air collecting chamber C112 are provided. The series air unit C3 inputs the first cooling air to the first air collecting chamber C111 through the first air inlet pipe C12, and the single air unit C2 inputs the second cooling air to the second air collecting chamber C112 through the second air inlet pipe C13. Since the single air unit C2 has only one fan, and the series air unit C3 has multiple independent fans 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 C5 is installed between the first air collecting chamber C111 and the second air collecting chamber C112. According to the thickness of the glass to be cooled, the fan connected to the first air collecting chamber C111 can be opened or closed, or the gate valve C5 can be opened or closed, so that the first air collecting chamber C111 and the second air collecting chamber C112 can obtain suitable wind pressure to ensure the production quality when the glass is cooled. For example, when it is necessary to cool thin tempered glass, both the single air unit C2 and the series air unit C3 are turned on, the wind pressure input to the first air collecting chamber C111 is higher, the wind pressure input to the second air collecting chamber C112 is lower, the gate valve C5 is closed, and the second air collecting chamber C112 and the second group of air outlet pipes C14 output cooling air with a lower component to the cooling section with a 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 C111 and the first group of air outlet pipes C14 output cooling air with a higher wind pressure in the passing section to quickly cool the glass, thereby improving production efficiency; conversely, when it is necessary to cool thick tempered glass, the series air unit C3 with a higher wind pressure connected to the first air collecting chamber C111 can be closed, or the series air unit C3 with a higher wind pressure connected to the first air collecting chamber C112 can be adjusted by rotating the gate C4. The wind pressure at the air outlet of the connected air unit C3 reduces the wind pressure at the air outlet of the series air unit C3, and then the gate valve C5 is opened, and the single air unit C2 with lower wind pressure connected to the second air collecting chamber C112 is opened, and the wind in the first air collecting chamber C111 is mixed with the wind in the second air collecting chamber C112 through the gate valve C5. The wind pressures of the first air collecting chamber C111 and the second air collecting chamber C112 are the same and both are low, so that the glass can pass through the cooling section and the passing section at a relatively low speed, and the same wind pressure cooling wind is output through the first group of air outlet pipes C14 and the second group of air outlet pipes C14, so that 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 ensuring the quality of the output glass.

[0038] In some embodiments, the drive output assembly C433 includes a screw rod C4331 and a screw rod seat C4332, wherein the screw rod C4331 is threadedly connected to the screw rod seat C4332, and the screw rod seat C4332 is fixed to the plate mounting seat C42; the other end of the second rocker arm C4322 is provided with a mounting hole C43221, and the hole center of the mounting hole C43221, the central axis of the screw rod seat C4332 and the hole center of the first mounting through hole C413 are located in the same straight line, and the screw rod C4331 passes through the hole center of the mounting hole C43221 and the screw rod seat C4332 in sequence and is fixedly connected to the first mounting through hole C413; the cylinder C431 drives the screw rod C4331 to rotate through the rocker arm assembly C432, and the screw rod C4331 performs telescopic motion in the left and right directions within the screw rod seat C4332 and the mounting hole C43221 while rotating. Figure 2 and 3 As shown, the cylinder C431 drives the rotating baffle plate unit C41 to rotate in the plate mounting base C42 with its own central axis as the rotating axis through the rocker assembly C432 and the drive output assembly C433. At the same time, the screw rod C4331 of the drive output assembly C433 can make telescopic movements in the left and right directions while rotating, thereby driving the rotating baffle plate unit C41 to make telescopic movements in the left and right directions, and then approach or move away from the wind shield plate assembly C421. In this way, when the rotating baffle unit C41 rotates and the rotating gate C4 closes to close the air inlet pipe, the rotating baffle unit C41 moves close to the wind shield assembly C421, avoiding the gap between the rotating baffle unit C41 and the wind shield assembly C421, improving the air tightness of the rotating gate C4, and thus avoiding air leakage in the air inlet pipe; when the rotating baffle unit C41 rotates and the rotating gate C4 opens to open the air inlet pipe, the rotating baffle unit C41 moves away from the wind shield assembly C421, thereby avoiding friction between the rotating baffle unit C41 and the wind shield assembly C421, and improving the smoothness of the rotation of the rotating baffle unit C41. Since the center of the mounting hole C43221, the central axis of the screw seat C4332 and the center of the first mounting through hole C413 are located in the same straight line, the straightness of the screw C4331 can be guaranteed, thereby ensuring the smoothness of the screw 4331 when rotating.

[0039] It is worth noting that the rotating shielding plate unit C41 is provided with a first opening C415, and the wind shielding plate assembly C421 is provided with a second opening C4215. When the rotating gate C4 is fully opened, the first opening C415 is aligned with the second opening C4215. Fig. 9As shown, the first opening C415 and the second opening C4215 play a role in guiding wind. When the rotating shielding plate unit C41 rotates to align the first opening C415 with the second opening C4215, the first opening C415 is connected with the second opening C4215, and wind can be discharged to the outside through the rotating gate C4. The first opening C415 and the second opening C4215 can be processed into different shapes, such as rectangular, circular, triangular or fan-shaped. The first opening C415 divides the rotating shielding plate unit C41 into a wind control connection part C412, a plurality of fan-shaped wind control parts C411 and a plurality of first arc parts C414. The vertex sides of all the fan-shaped wind control parts C411 are connected through the wind control connection part C412, and the arc sides of two adjacent fan-shaped wind control parts C411 are connected through the first arc part C414. The wind control connection part C412 is arranged on the central axis of the plate mounting seat C42, and the first mounting through hole C413 is arranged on the wind control connection part C412. Figure 1 , 7 As shown in Figure 8, the lead screw 4331 drives the wind control connection part C412 to rotate and drives the wind control connection part C412 to perform telescopic movement in the inner and outer directions of the wind control port C321, so that the wind control connection part C412 drives all the fan-shaped wind control parts C411 to perform the same rotation and the same telescopic movement. Since the fan-shaped wind control part C411 is a fan-shaped structure, when rotating and performing telescopic movement, the arc side of the fan-shaped wind control part C411 always matches the shape of the inner wall of the plate mounting seat C42 of the cylindrical tube structure and will not touch the inner wall of the plate mounting seat C42, thereby ensuring the smoothness of the rotation of the rotating shielding plate unit C41. The first arc portion C414 serves to reinforce the rotating shielding plate unit C41, so that the arc side of all the fan-shaped covering parts C4211 are connected, thereby improving the firmness and not being easily damaged when subjected to strong winds.

[0040] Optionally, the wind shield assembly C421 is provided with a plurality of second openings C4215, and the second openings C4215 divide the wind shield assembly C421 into a shielding connection portion C4212, a plurality of fan-shaped covering portions C4211, and a plurality of second arc portions C4214, the arc side of the fan-shaped covering portion C4211 is fixedly connected to the inner wall of the plate mounting seat C42, and the vertex sides of all the fan-shaped covering portions C4211 are connected via the shielding connection portion C4212. The arc sides of two adjacent fan-shaped covering parts C4211 are connected by the second arc part C4214, and the second arc part C4214 is fixedly connected to the inner wall of the plate mounting seat C42; the shielding connection part C4212 is arranged on the central axis of the plate mounting seat C42, and the shielding connection part C4212 is provided with a second mounting through hole C4213, and the lead screw 4331 passes through the second mounting through hole C4213 and rotates in the second mounting through hole C4213. Figure 5As shown, since the fan-shaped cover portion C4211 is a fan-shaped structure, the arc side of the fan-shaped cover portion C4211 can cooperate with the inner wall of the plate mounting seat C42, and combined with the wind shielding effect of the second arc portion C4214, it can prevent the wind control port C321 from leaking air after the rotating gate C4 is closed. In addition, since the vertex sides of all the fan-shaped cover portions C4211 are connected through the shielding connection portion C4212, the wind shielding plate assembly C421 can be stably fixed to the inner wall of the plate mounting seat C42, and it is not easy to separate from the plate mounting seat C42 even when subjected to strong winds. The shielding connection portion C4212 also plays a role in supporting the lead screw 4331, and the lead screw 4331 is fixed to the plate mounting seat C42 through the shielding connection portion C4212, so that its own connecting shaft 431 can rotate relative to the plate mounting seat C42, thereby driving the rotating shielding plate unit C41 to rotate. In this embodiment, when the wind shield plate assembly C421 and the rotating shield plate unit C41 are staggered to close the rotating gate C4, the surface formed by the fan-shaped wind control part C411, the wind control connection part C412, the fan-shaped covering part C4211 and the shielding connection part C4212 can cover the entire cross-sectional area of ​​the plate mounting seat C42, thereby achieving the purpose of closing the rotating gate C4.

[0041] Specifically, the fan-shaped wind control parts C411 are arranged at intervals in the plate mounting seat C42, and the fan-shaped covering parts C4211 are arranged at intervals in the plate mounting seat C42. The number of the fan-shaped wind control parts C411 is equal to the number of the fan-shaped covering parts C4211. When the rotary gate C4 is closed, the fan-shaped wind control parts C411 and the fan-shaped covering parts C4211 are staggered. Figure 1 , 9As shown in Figures 11 and 11, the inner side of the wind control port C321 of the combined air duct C32 is the air inlet, and the outer side of the wind control port C321 is the air outlet. The more the number of the fan-shaped wind control parts C411 and / or the number of the fan-shaped covering parts C4211, the smaller the angle that the fan-shaped wind control part C411 needs to rotate when the rotating gate C4 is opened and closed, and the higher the requirement for the rotation accuracy. After the rotating gate C4 is closed, the structure of the fan-shaped wind control parts C411 and the fan-shaped covering parts C4211 that are staggered can make the fan-shaped wind control parts C411 overlap with the fan-shaped covering parts C4211 when the rotating gate C4 is opened, so that the first opening C415 is aligned with the second opening C4215, so that the wind can be evenly discharged from the air outlet of the flip gate. Preferably, the rotating baffle unit C41 includes two fan-shaped wind control parts C411, which are relatively arranged on both sides of the wind control connection part C412; the wind shield assembly C421 includes two fan-shaped covering parts C4211, which are relatively arranged on both sides of the covering connection part C4212, and the angular arc of the fan-shaped covering part C4211 is 90°. When the angular curvature of the fan-shaped covering portion C4211 is greater than 90°, the maximum angular curvature of a single air inlet is less than 90°, which makes the area of ​​the air inlet too small and is not conducive to strong wind flowing through; when the angular curvature of the fan-shaped covering portion C4211 is less than 90°, the maximum angular curvature of a single air inlet is greater than 90°, the arc length of the air inlet is too long, and the angle at which the rotating baffle unit C41 needs to rotate is too large, which is not conducive to the rapid opening and closing of the rotating gate C4; when the angular curvature of the fan-shaped covering portion C4211 is 90°, it is not only conducive to the flow of strong winds, but also conducive to the rapid opening and closing of the rotating gate C4.

[0042] like Figure 1 , 7 As shown in Figures 8 and 9, the rotating shielding plate unit C41 is arranged on the air inlet side of the plate mounting seat C42, and the wind shielding plate assembly C421 is arranged on the air outlet side of the plate mounting seat C42. In this way, after the rotating gate C4 is completely closed, strong wind blows to the surface of the rotating shielding plate unit C41, thereby pressing the rotating shielding plate unit C41 against the wind shielding plate assembly C421, further improving the sealing performance and avoiding air leakage. It is worth noting that a sealing portion C422 is provided at the edge of the second opening C4215. Figure 1 , 4 As shown in FIG. 9 , the sealing portion C422 can further ensure the air tightness of the rotating gate C4, and after the rotating gate C4 is completely closed, it is not easy to leak air. Optionally, the plate mounting seat C42 is provided with a protective net C423, and the area of ​​the protective net C423 is equal to the cross-sectional area of ​​the plate mounting seat C42. Figure 2 As shown, the protective net C423 can effectively isolate large objects floating in the air duct, thereby preventing the floating large objects from damaging the equipment in the air duct.

[0043] The gate valve C5 includes an installation pipe C51, a first cylinder driving member C52, a second cylinder driving member C53, a first gate C54 and a second gate C55; the installation pipe C51 is installed on the partition between the first air collecting chamber C111 and the second air collecting chamber C112, and the first air collecting chamber C111 and the second air collecting chamber C112 are connected through the installation pipe C51; the first cylinder driving member C52 and the second cylinder driving member C53 are respectively installed on the top surface and the bottom surface of the installation pipe C51; the lower end of the first gate C54 passes through the upper side wall of the installation pipe C51 and is inserted into the installation pipe C51, and the upper end of the second gate C55 passes through the lower side wall of the installation pipe C51. The wall is inserted into the installation pipe C51, the upper end of the first gate C54 is transmission-connected to the output end of the first cylinder driving component C52, and the lower end of the second gate C55 is transmission-connected to the output end of the second cylinder driving component C53; the first cylinder driving component C52 drives the first gate C54 to move up and down, and the second cylinder driving component C53 drives the second gate C55 to move up and down, and the second gate C55 and the first gate C54 are arranged in a front-to-back arrangement, and when the first gate C54 slides to the maximum stroke, the first gate C54 completely covers the installation pipe C51, and when the second gate C55 slides to the maximum stroke, the second gate C55 covers a part of the installation pipe C51. Fig.15 , 18As shown in Figure 19, the first gate C54 or the second gate C55 can be controlled to move up and down respectively by the first cylinder driving component C52 or the second cylinder driving component C53, thereby controlling the opening and closing of the gate valve C5, and further controlling the connection or isolation of the first air collecting chamber C111 and the second air collecting chamber C112, so as to adjust the wind pressure output by the first group of air outlet pipes C14 and the second group of air outlet pipes C14. The first air collecting chamber C111 and the second air collecting chamber C112 are connected through the gap between the first gate C54 and the second gate C55. As the first gate C54 moves downward and the second gate C55 moves upward, the lower end of the first gate C54 and the upper end of the second gate C55 gradually approach each other, and the gap between the lower end of the first gate C54 and the upper end of the second gate C55 gradually decreases, and the air flow in the gap also decreases. When the lower end of the first gate C54 passes over the upper end of the second gate C55 downward, the channel for air supply is the channel between the first gate C54 and the second gate C55. The gap between the two plate surfaces reaches the maximum stroke when the lower end of the first gate plate C54 passes over the lower side of the installation pipe C51, and the installation pipe C51 is completely isolated and in a completely closed state; in the process from fully open to fully closed, the air supply channel of the installation pipe C51 is gradually reduced; similarly, in the process from fully closed to fully open, the wind flow conveying channel of the installation pipe C51 is also gradually expanded. When the wind pressure of the fan remains unchanged, the wind pressure fluctuation of the airflow conveyed in the installation pipe C51 is small, which can effectively avoid the appearance of air mark defects on the glass surface due to excessive wind pressure changes.

[0044] The front end of the first air collecting chamber C111 and the front end of the second air collecting chamber C112 are both connected to a plurality of air outlet pipes C14 distributed in an array. The first air collecting chamber C111 supplies air to the passing section of the glass tempering furnace through the air outlet pipes C14, and the second air collecting chamber C112 supplies air to the cooling section of the glass tempering furnace through the air outlet pipes C14. The front end of the first air collecting chamber C111 and the front end of the second air collecting chamber C112 are respectively installed with the air outlet regulating device C6, and the air outlet regulating device C6 includes a lifting mechanism C62 and a shielding plate C61, and the shielding plate C61 is transmission-connected to the lifting mechanism C62, and the lifting mechanism C62 drives the shielding plate C61 to move up and down. When moving up and down, the shielding plate C61 shields a row of the air outlet pipes C14 or the area between the upper and lower rows of the air outlet pipes C14. Figure 16-18 As shown, the upper and lower heights of the shielding plate C61 can be adjusted by the air outlet adjustment device C6, and an exhaust air duct C14 can be partially or completely covered, or all of the air outlet ducts C14 can be left uncovered, so as to achieve the purpose of adjusting the wind pressure and wind speed output by the air outlet duct C14 and ensure the production quality of tempered glass cooling.

[0045] Optionally, the end edge of the lower end of the first gate C54 is an arc-shaped protruding toward the center direction of the installation pipe C51; the end edge of the upper end of the second gate C55 and the lower end edge of the first gate C54 are arc-shaped 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 slowly, the control of the first gate C54 and the second gate C55 is more stable, and the cylinder is not easily damaged. The gate valve C5 also includes a plurality of guide plates C57, and the guide plates C57 are provided with guide grooves. The plurality of guide plates C57 are grouped in pairs and symmetrically installed on the front and rear sides of the partition respectively, and the guide plates C57 are distributed on the upper and lower sides of the installation pipe C51; the first gate C54 and the second gate C55 slide along the corresponding guide grooves of the guide plates C57. Fig.18 As shown, the left and right sides of the first gate plate C54 or the second gate plate C55 move up and down in the guide groove of the corresponding guide plate C57, which can ensure that the first gate plate C54 and the second gate plate C55 will not swing left and right when moving up and down, further improving the operating stability of the air collecting box C1 with wind pressure regulating function.

[0046] Preferably, the air outlet adjustment device C6 further includes a driving motor C63, and the driving motor C63 is installed on the outside of the box body C11; the lifting mechanism C62 further includes a conducting wheel C621, a conducting chain C622 and a connecting rod C623; the connecting rod C623 is installed below the shielding plate C61, and one end of the connecting rod C623 is drivingly connected to the output end of the driving motor C63; the plurality of conducting wheels C621 are divided into two groups, the conducting wheels C621 of the first group are arranged at intervals and are sleeved on the connecting rod C623, and the conducting wheels C621 of the second group are arranged at intervals and sleeved on the connecting rod C623. The wheels C621 are installed above the shielding plate C61, and the second group of the conduction wheels C621 and the first group of the conduction wheels C621 are arranged one by one with the shielding plate C61 between them; every two of the conduction wheels C621 corresponding to each other are equipped with the conduction chain C622, and the conduction chain C622 is connected to the rear side of the shielding plate C61; the driving motor C63 drives the conduction wheels C621 to rotate forward and reverse through the connecting rod C623, thereby driving the conduction chain C622 to move up and down, and then driving the shielding plate C61 to move up and down synchronously. Figure 16-18As shown, by driving the motor C63, the conduction wheel C621, the conduction chain C622 and the connecting rod C623 to drive the baffle plate C61 to move up and down synchronously, the first exhaust air duct C14 or the second exhaust air duct C14 can be covered by the baffle plate C61, thereby ensuring that the wind pressure and wind speed of the cooling air output by each air outlet duct C14 of the first exhaust air duct C14 or the second exhaust air duct C14 are the same, thereby keeping the surface temperature of the tempered glass cooling down at a relatively consistent speed, thereby preventing quality accidents such as glass shattering.

[0047] Furthermore, the box C11 is also provided with four supporting feet C113, which are respectively installed below the four corners of the box C11; the bottom surfaces of the four supporting feet C113 are located on the same plane. Fig.18 As shown, the bottom surfaces of the four support legs C113 are located on the same plane, which can make the box body C11 have better installation stability and improve the operating stability of the air collecting box C1 with wind pressure regulation function. Furthermore, the box body C11 is also provided with a bottom plate C114; the bottom plate C114 is located below the first air collecting cavity C111 and the second air collecting cavity C112, and the distance between the rear bottom edge of the bottom plate C114 away from the air outlet pipe C14 and the bottom surface of the support legs C113 is greater than the distance between the front bottom edge of the bottom plate C114 close to the air outlet pipe C14 and the bottom surface of the support legs C113. Fig.18 As shown, the air collecting box C1 is installed near the cooling section and the passing section of the tempered glass output by the glass tempering furnace. The tempered glass running from right to left is located on the front side of the box body C11. The cold air with the tempered glass blows downward on the surface of the tempered glass. The cold air that has exchanged heat becomes hot air carrying heat and then passes through the bottom of the bottom plate C114 and is discharged to the back side of the box body C11. The bottom plate C114 is set to be inclined, and the rear bottom edge of the bottom plate C114 away from the air outlet pipe C14 is higher than the front bottom edge of the bottom plate C114, which is beneficial to the discharge and diffusion of hot air and the improvement of the cooling efficiency of the tempered glass. Furthermore, it also includes a pressure gauge C7; the two pressure gauges C7 are respectively installed on the outer side surfaces of the left and right sides of the box body C11, and the pressure gauge C7 is used to measure the wind pressure of the first air collecting chamber C111 or the second air collecting chamber C112. As shown Fig.12 and 13 As shown, the pressure gauge C7 can effectively monitor the wind pressure of the first air collecting chamber C111 and the second air collecting chamber C112, so that the operator can open and close the gate valve C5 or start and close the series fan unit C3 in time to adjust the output wind pressure, thereby controlling the wind pressure of the first air collecting chamber C111 and the second air collecting chamber C112 to meet the requirements of the production process. Furthermore, the box body C11 is also provided with a maintenance door C8; the two maintenance doors C8 are respectively installed on the left and right sides of the box body C11, and the pressure gauge C7 is located in front of or behind the maintenance door C8. Fig.13 and 14As shown, the equipment and facilities in the first air collecting chamber C111 or the second air collecting chamber C112 can be repaired and maintained timely and effectively through the maintenance door C8. Furthermore, the top surface of the box body C11 is also provided with two lifting ears C115; the midpoint of the line connecting the two lifting ears C115 and the center of gravity of the box body C11 are on the same vertical line; the connection angles in the box body C11 are all arc angles. Fig.12 and 14 As shown, the wind collecting box C1 with wind pressure regulating function can be stably lifted by two lifting ears C115, which makes disassembly and installation more convenient. The connection angles in the box body C11 are all arc angles, which can reduce the wind speed loss in the box body C11 and improve the utilization rate of cooling air.
