The physical tempering method is currently 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. During the heating process, the heating stability of the glass is very important, and during the cooling process, the stability of the cooling wind of the glass is also very important.

[0014] One of the above technical solutions has the following beneficial effects:

[0015] 1. After the hot air is blown to the glass, the heat of the hot air is absorbed by the glass, the temperature of the glass rises, and the temperature of the hot air after the heat is absorbed decreases, and is absorbed by the air inlet of the convection device, and then blown from the air outlet of the convection device to the air inlet of the heating furnace. The hot air with the reduced temperature passes through the heating component, and is thus reheated and the temperature rises. The convection device improves the utilization rate of the hot air in the heating furnace, thereby improving the heating efficiency.

DETAILED DESCRIPTION

[0033] Combine the following Figures 1 to 15 , describes an accurate and stable glass tempering system according to an embodiment of the present invention, comprising a loading platform 1, a heating furnace 2, a cooling air grille 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 grille 3 and the lowering platform 4; Figure 2The furnace top array of the heating furnace 2 is shown as having a plurality of convection devices 21 distributed therein, the air inlet of the convection device 21 is connected to the air outlet of the heating furnace 2, 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 to the glass, the heat of the hot air is absorbed by the glass, the temperature of the glass rises, the temperature of the hot air after the heat is absorbed decreases, and is absorbed by the air inlet of the convection device 21, and then blown from the air outlet of the convection device 21 to the air inlet of the heating furnace 2, the hot air with the temperature reduced passes through the heating component, and is thus reheated and the temperature rises. 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. The air supply module 6 includes an air collecting box 61 and a series fan assembly 63, the air collecting box 61 includes a box body 611, an air inlet pipe and an air outlet pipe 614, the air collecting cavity in the box body 611 and the air outlet of the series fan assembly 63 are connected through the air inlet pipe, and the air collecting cavity in the box body 611 and the air inlet of the cooling air grid 3 are connected through the air outlet pipe 614; the series fan assembly 63 includes an independent fan 631, a series air duct 632 and a rotating shutter 64, a plurality of 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 with the rotating gate 64, and the rotating gate 64 includes an adjustment cover 641, and the rotating gate 64 is used to adjust the opening of the adjustment opening 6321 by rotating the adjustment cover 641. The opening of the adjustment opening 6321 can be accurately controlled by the rotating gate 64, and the wind pressure of the air outlet of the series air duct 632 can be adjusted, so as to achieve the purpose of indirectly controlling the outlet pressure of the air collecting box 61, and then accurately adjusting the wind pressure of the cold air blown out by the cooling air grid 3, so as to ensure the stability of glass cooling and the quality of the finished glass. When making thin glass, the rotary gate 64 is closed, and all independent fans 631 work at the same time. The previous independent fan 631 blows air into the next independent fan 631, and finally the last independent fan 631 blows air into the air collecting box 61. When multiple fans are used in series, the total output wind pressure is the superposition of the wind pressures of the multiple independent fans 631. 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 631 closest to the air inlet pipe needs to be turned on. At this time, the rotary gate 64 is opened, and the wind from the external environment enters the independent fan 631 from the rotary gate 64, thereby achieving the purpose of energy saving.The cold air blown by the fan enters the air collecting cavity in the box body 611 from the air inlet pipe, and then the wind pressure is evenly distributed in the air collecting cavity. Then, the cold air is blown from the air outlet pipe 614 of the air collecting box 61 to the cooling air grille 3, and then blown to the hot glass through the cooling air grille 3, so as to cool the glass.

[0034] The specific process of processing glass in the glass tempering system is as follows: Figure 1 As shown, 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 achieve the purpose of improving 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 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 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, so as to adjust the wind pressure of the cold air blown to the glass surface; after the glass is cooled after passing through the cooling air grid 3, it is transported to the lower table 4 through the conveying roller 5 to form a finished tempered glass.

[0035] In some embodiments, Figure 2 and 3 The air supply module 6 shown in the figure also includes a single fan assembly 62; specifically, the single fan assembly 62 is a single fan, and the air outlet of the single fan assembly 62 is the air outlet of the fan. The air collecting chamber is divided into a first air collecting chamber 6111 and a second air collecting chamber 6112, and a gate valve 65 is provided between the first air collecting chamber 6111 and the second air collecting chamber 6112, and 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 air inlet pipe is divided into a first air inlet pipe 612 and a second air inlet pipe 613, and the first air inlet pipe 612 and the second air inlet pipe 613 are both installed on the rear side of the box body 611, and the front end of the first air inlet pipe 612 is connected to the first air inlet pipe 612. The rear end of the first air collecting chamber 6111 is connected, the front end of the second air inlet pipe 613 is connected to the rear end of the second air collecting chamber 6112, the rear end of the first air inlet pipe 612 is connected to the air outlet of the series fan assembly 63, and the rear end of the second air inlet pipe 613 is connected to the air outlet of the single fan assembly 62; the glass heated at high temperature by the heating furnace 2 needs to be cooled after it comes out of the furnace. The thicker the glass, the slower the cooling speed. Too fast cooling speed will cause the glass to crack and 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. Figure 1 , 2As shown in , 3 and 14, 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 to the first air collecting chamber 6111 through the first air inlet pipe 612, and the single fan assembly 62 inputs the second cooling air to 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 fan 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 can obtain suitable wind pressure to ensure the production quality when the glass is cooled. 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, and the gate valve 65 is closed, and cooling air with a lower component is output to the cooling section with a higher glass temperature through the second air collecting chamber 6112 and the second group of air outlet pipes 614, 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 a higher 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 a higher wind pressure connected to the first air collecting chamber 6111 can be closed, or the rotating gate 64 can be used to adjust the The wind pressure at the air outlet of the series fan assembly 63 is reduced, and then the gate 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 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 614 and the second group of air outlet pipes 614, 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.

[0036] like Fig.13 and 15The gate valve 65 shown 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 top surface and the bottom surface of the connecting pipe 651; the lower end of the first gate plate 654 passes through the upper side wall of the connecting pipe 651 and is inserted into the connecting pipe 651, and the upper end of the second gate plate 655 passes through the lower wall of the connecting pipe 651. The side wall is inserted into the connecting pipe 651, the upper end of the first gate plate 654 is transmission connected to the output end of the first cylinder 652, and the lower 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 up and down, and the second cylinder 653 drives the second gate plate 655 to move up and down, the second gate plate 655 and the first gate plate 654 are arranged spaced apart from each other up and down, 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 up and down respectively by the first cylinder 652 or the second cylinder 653, 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 downward and the second damper 655 moves upward, the lower end of the first damper 654 and the upper end of the second damper 655 gradually approach each other, and the gap between the lower end of the first damper 654 and the upper end of the second damper 655 gradually decreases, and the air flow in the gap also decreases accordingly. When the lower end of the first damper 654 passes over the upper end of the second damper 655 downward, the channel for air supply is the gap between the first damper 654 and the second damper 655. The gap between the two plate surfaces reaches the maximum stroke when the lower end of the first gate plate 654 passes over the lower side of the connecting pipe 651, and the connecting pipe 651 is completely isolated and is in a completely closed state; in the process from fully open to fully closed, the air supply channel of the connecting pipe 651 is gradually reduced; similarly, in the process from fully closed to fully open, the wind flow conveying channel of the connecting pipe 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 pipe 651 is small, which can effectively avoid the appearance of air mark defects on the glass surface due to excessive wind pressure changes.

[0037] It is worth noting that if Fig.15 As shown, the end edge of the lower 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 upper end of the second gate plate 655 is an arc-shaped protruding toward the center direction of the connecting pipe 651; the end edge of the lower end of the first gate plate 654 and the end edge of the upper end of the second gate plate 655 are set to be a protruding arc shape. When the two gate plates are close to each other and the arc-shaped ends of the first gate plate 654 and the second gate plate 655 overlap, the ventilation area changes in a curve, and the change in the force of the wind acting on the plate surface is relatively gentle, so that the force change of the cylinder output is smoother, the control of the first gate plate 654 and the second gate plate 655 is more stable, and the cylinder is not easily damaged. The gate valve 65 further includes a plurality of guide plates 656; guide grooves are provided in the guide plates 656, and the plurality of guide plates 656 are symmetrically installed on the upper and lower sides of the partition in groups of two, and the guide plates 656 are distributed on the upper and lower sides of the connecting pipe 651; the first gate plate 654 and the second gate plate 655 slide along the guide grooves of the corresponding guide plates 656. The front and rear sides of the first gate plate 654 or the second gate plate 655 move up and down in the guide grooves of the corresponding guide plates 656, which can ensure that the first gate plate 654 and the second gate plate 655 will not swing left and right when moving up and down, further improving the operating stability of the air collecting box 61 with wind pressure regulating function.

[0038] Alternatively, if Fig.12 , 14 As shown in 15, 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 cooling air grille 3 through the air outlet pipe 614, and the second air collecting chamber 6112 supplies air to the cooling section of the cooling air grille 3 through the air outlet pipe 614; 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 regulating device 66, the air outlet regulating device 66 includes a lifting device 662 and a wind shield 661, the wind shield 661 is transmission-connected to the lifting device 662, 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 an exhaust air duct 614 can be partially or completely covered, or all of the air outlet ducts 614 can be left uncovered, so as to adjust the wind pressure and wind speed output by the air outlet duct 614 and ensure the production quality of tempered glass cooling.

[0039] Specifically, Fig.12 , 14As shown in Figure 15, the air outlet adjustment device 66 also includes a drive motor 663, and the drive motor 663 is installed on the outside of the box body 611; the lifting device 662 also includes a transmission wheel 6621, a transmission chain 6622 and a connecting rod 6623; the connecting rod 6623 is installed below the wind shield 661, and one end of the connecting rod 6623 is connected to the output end of the drive motor 663; the plurality of transmission wheels 6621 are divided into two groups, the transmission wheels 6621 of the first group are arranged at intervals and are mounted on the connecting rod 6623, and the transmission wheels 6621 of the second group are arranged at intervals and are mounted on the connecting rod 6623. The driving wheel 6621 is installed above the wind shield 661, and the second group of the driving wheels 6621 and the first group of the driving wheels 6621 are arranged one by one with respect to the wind shield 661; every two of the driving wheels 6621 corresponding to each other are provided with a driving chain 6622, and the driving chain 6622 is connected to the rear side of the wind shield 661; the driving motor 663 drives the driving wheel 6621 to rotate forward and reverse through the connecting rod 6623, thereby driving the driving chain 6622 to move up and down, and then driving the wind shield 661 to move up and down synchronously. By driving the wind shield 661 up and down synchronously through the driving motor 663, the transmission wheel 6621, the transmission chain 6622 and the connecting rod 6623, the first exhaust air duct 614 or the second exhaust air duct 614 can be covered by the wind shield 661, thereby ensuring that the wind pressure and wind speed of the cooling air output by each air outlet duct 614 of the first exhaust air duct 614 or the second exhaust air duct 614 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.

[0040] Specifically, Fig.15The box body 611 is also provided with four supporting feet 6113, which are respectively installed below the four corners of the box body 611; the bottom surfaces of the four supporting feet 6113 are in the same plane; the bottom surfaces of the four supporting feet 6113 are 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 cooling air grille 3. The tempered glass running from right to left is located on the front side of the box body 611. The cold wind of 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 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 cooling efficiency of the tempered glass.

[0041] Furthermore, it also includes a pressure gauge 67; two pressure gauges 67 are respectively installed on the outer side surfaces of the left and right sides of the box body 611, and the pressure gauge 67 is used to measure the wind pressure of the first air collecting cavity 6111 or the second air collecting cavity 6112. Figure 4 and 12 As shown, the wind pressure of the first air collecting chamber 6111 and the second air collecting chamber 6112 can be effectively monitored through the pressure gauge 67, so that the operator can open and close the gate valve 65 in time, or start and close the series fan assembly 63 to adjust the output wind pressure, and then control the wind pressure of the first air collecting chamber 6111 and the second air collecting chamber 6112 to meet the requirements of the production process. Furthermore, the box body 611 is also provided with a maintenance door 68; the two maintenance doors 68 are respectively installed on the left and right sides of the box body 611, and the pressure gauge 67 is located on the front or rear side of the maintenance door 68. As shown in the figure and, the equipment and facilities in the first air collecting chamber 6111 or the second air collecting chamber 6112 can be repaired and maintained in a timely and effective manner through the maintenance door 68. Furthermore, two lifting ears 6115 are also provided on the top surface of the box body 611; the midpoint of the line connecting the two lifting ears 6115 and the center of gravity of the box body 611 are on the same vertical line; the connection angles in the box body 611 are all arc angles. As shown Figure 4 and 12As shown, the wind collecting box 61 with wind pressure regulating function can be stably lifted by two lifting ears 6115, and disassembly and installation are more convenient. The connection angles in the box body 611 are all arc angles, which can reduce the wind speed loss in the box body 611 and improve the utilization rate of cooling air.

[0042] Preferably, Figure 5 and 6As shown, the rotating gate 64 also includes a gate seat 642 and a driving mechanism 643. 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, it can rotate in the gate seat 642 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, and 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 reduction motor 6431 and a driving output assembly 6432, the driving output assembly 6432 is fixedly connected to the first connecting hole 6413, the rotating shaft of the reduction motor 6431 is transmission-connected to the driving output assembly 6432, and the reduction motor 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 assembly 6432; when the adjusting cover 641 and the baffle assembly 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 baffle assembly 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 adjusting cover plate 641 , the opening of the rotating shutter plate 64 can be adjusted, thereby adjusting the opening of the adjusting opening 6321 to achieve the purpose of controlling the wind pressure.When the adjusting cover 641 rotates and the rotating gate 64 is closed, the adjusting opening 6321 is closed, and the adjusting cover 641 moves toward the direction close to the baffle assembly 6421. When the rotating gate 64 is completely closed, the adjusting cover 641 moves close to the baffle assembly 6421, avoiding the gap between the adjusting cover 641 and the baffle assembly 6421, improving the air tightness of the rotating gate 64, avoiding the inaccurate wind pressure of the wind collecting box 61 caused by the air leakage of the rotating gate 64, 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 3 remains stable, improving the quality of the finished glass. In addition, the rotating gate 64 saves more space than the plug-in gate due to the rotating opening and closing structure, thereby increasing the application flexibility of the rotating gate 64.

[0043] In some embodiments, Figure 5 and 6The drive output assembly 6432 shown in the figure includes a commutator 643A, a screw 643B and a screw seat 643C, the input portion of the commutator 643A is connected to the rotating shaft of the reduction motor 6431, the output portion of the commutator 643A is connected to the screw 643B, the screw 643B is threadedly connected to the screw seat 643C, and the screw seat 643C is fixed to the gate seat 642; the central axis of the output portion of the commutator 643A and the central axis of the screw seat 643C The center of the first connection hole 6413 is located in the same straight line, and the screw rod 643B passes through the output part of the commutator 643A and the screw rod seat 643C in sequence and is fixedly connected to the first connection hole 6413; the reduction motor 6431 drives the screw rod 643B to rotate through the commutator 643A, and the screw rod 643B performs telescopic movement in the screw rod seat 643C and the output part of the commutator 643A along the inner and outer directions of the adjustment opening 6321 while rotating. The reduction motor 6431 drives the adjustment cover plate 641 to rotate in the gate seat 642 with its own central axis as the rotation axis through the drive output assembly 6432, and the screw rod 643B of the drive output assembly 6432 can perform telescopic movement in the inner and outer directions of the adjustment opening 6321 while rotating, thereby driving the adjustment cover plate 641 to perform telescopic movement in the same direction, and then approach or move away from the shielding plate assembly 6421. In this way, when the adjusting cover 641 rotates and closes the rotating gate 64 to close the adjusting opening 6321, the adjusting cover 641 moves toward the direction close to the baffle assembly 6421, and finally the adjusting cover 641 will be completely close to the surface of the baffle assembly 6421, avoiding the existence of a gap between the adjusting cover 641 and the baffle assembly 6421, improving the air tightness of the rotating gate 64, and preventing air leakage in the closed adjusting opening 6321; when the adjusting cover 641 rotates and opens the rotating gate 64 to open the adjusting opening 6321, the adjusting cover 641 moves 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 commutator 643A, the central axis of the screw seat 643C and the center of the first connecting hole 6413 are located in the same straight line, the straightness of the screw 643B can be guaranteed, thereby ensuring the smoothness of the screw during rotation.

[0044] It is worth noting that if Figure 6The adjustment cover 641 is provided with a first opening 6415, and the shielding plate assembly 6421 is provided with a second opening 642E. When the rotating gate 64 is fully opened, the first opening 6415 is aligned with the second opening 642E. The first opening 6415 and the second opening 642E play a role in guiding wind. When the adjustment cover 641 is rotated to align the first opening 6415 with the second opening 642E, the first opening 6415 is connected with the second opening 642E, and wind can be discharged to the outside through the rotating gate 64. The first opening 6415 and the second opening 642E can be processed into different shapes, such as rectangular, circular, triangular or fan-shaped. The first opening 6415 divides the regulating cover plate 641 into a first connecting portion 6412, a plurality of fan-shaped rotating portions 6411, and a plurality of first arc connecting segments 6414. The vertex sides of all the fan-shaped rotating portions 6411 are connected through the first connecting portion 6412, and the arc sides of two adjacent fan-shaped rotating portions 6411 are connected through the first arc connecting segment 6414. The first connecting portion 6412 is arranged on the central axis of the gate seat 642, and the first connecting hole 6413 is arranged on the first connecting portion 6412. Figure 5-11 As shown, the driving mechanism 643 drives the first connecting part 6412 to rotate and drives the first connecting part 6412 to perform telescopic movement in the inner and outer directions of the adjusting opening 6321, so that the first connecting part 6412 drives all the fan-shaped rotating parts 6411 to perform the same rotation and the same telescopic movement. Since the fan-shaped rotating part 6411 is a fan-shaped structure, when rotating and performing telescopic movement, the arc side of the fan-shaped rotating part 6411 always matches the shape of the inner wall of the gate seat 642 of the cylindrical tube structure and does not touch the inner wall of the gate seat 642, ensuring the smoothness of the rotation of the adjusting cover 641. The first arc connecting section 6414 plays the role of reinforcing the adjusting cover 641, so that the arc side of all the fan-shaped shielding parts 642A are connected, thereby improving the firmness and not being easily damaged when subjected to strong winds.

[0045] Specifically, Figure 6The shielding plate assembly 6421 shown in the figure is provided with a plurality of second openings 642E, and the second openings 642E divide the shielding plate assembly 6421 into a second connecting portion 642B, a plurality of fan-shaped shielding portions 642A and a plurality of second circular arc connecting segments 642D, the circular arc side of the fan-shaped shielding portion 642A is fixedly connected to the inner wall of the gate seat 642, the vertex sides of all the fan-shaped shielding portions 642A are connected through the second connecting portion 642B, the circular arc sides of two adjacent fan-shaped shielding portions 642A are connected through the second circular arc connecting segment 642D, and the second circular arc connecting segment 642D is fixedly connected to the inner wall of the gate seat 642; the second connecting portion 642B is arranged on the central axis of the gate seat 642, the second connecting portion 642B is provided with a second connecting hole 642C, and the lead screw 643B passes through the second connecting hole 642C and rotates in the second connecting hole 642C. Since the fan-shaped shielding portion 642A is a fan-shaped structure, the arc side of the fan-shaped shielding portion 642A can cooperate with the inner wall of the gate seat 642, and combined with the wind-blocking effect of the second arc connecting section 642D, it is possible to prevent the adjustment opening 6321 from leaking air after the rotating gate 64 is closed. In addition, since the vertex sides of all the fan-shaped shielding portions 642A are connected through the second connecting portion 642B, the shielding plate assembly 6421 can be stably fixed to the inner wall of the gate seat 642, and it is not easy to separate from the gate seat 642 even in strong winds. The second connecting portion 642B also plays a role in supporting the lead screw 643B, and the lead screw 643B is fixed to the gate seat 642 through the second connecting portion 642B, so that its own connecting shaft can rotate relative to the gate seat 642, thereby driving the adjustment cover 641 to rotate. In this embodiment, when the baffle assembly 6421 and the adjustment cover 641 are staggered to close the rotating gate 64, the surface formed by the fan-shaped rotating portion 6411, the first connecting portion 6412, the fan-shaped baffle portion 642A and the second connecting portion 642B can cover the entire cross-sectional area of ​​the gate seat 642, thereby achieving the purpose of closing the rotating gate 64.

[0046] like Figure 5 , 6As shown in Figures 9 and 10, the fan-shaped rotating parts 6411 are arranged at intervals in the gate seat 642, and the fan-shaped shielding parts 642A are arranged at intervals in the gate seat 642. The number of the fan-shaped rotating parts 6411 is equal to the number of the fan-shaped shielding parts 642A. When the rotating gate 64 is closed, the fan-shaped rotating parts 6411 and the fan-shaped shielding parts 642A are staggered. The inner side of the adjustment opening 6321 of the series air duct 632 is the air inlet, and the outer side of the adjustment opening 6321 is the air outlet. The more the number of the fan-shaped rotating parts 6411 and / or the number of the fan-shaped shielding parts 642A, the smaller the angle that the fan-shaped rotating parts 6411 need to rotate when the rotating gate 64 is opened and closed, and the higher the requirement for the rotation accuracy. The structure of the fan-shaped rotating parts 6411 and the fan-shaped shielding parts 642A that are staggered after the rotating gate 64 is closed can make the fan-shaped rotating parts 6411 overlap with the fan-shaped shielding parts 642A when the rotating gate 64 is opened, so that the first opening 6415 is aligned with the second opening 642E, so that the wind energy is evenly discharged from the air outlet of the flip gate. Preferably, the regulating cover 641 includes two fan-shaped rotating parts 6411, and the two fan-shaped rotating parts 6411 are relatively arranged on both sides of the first connecting part 6412; the shielding plate assembly 6421 includes two fan-shaped shielding parts 642A, and the two fan-shaped shielding parts 642A are relatively arranged on both sides of the second connecting part 642B, and the angular arc of the fan-shaped shielding parts 642A is 90°. When the angular curvature of the fan-shaped shielding portion 642A 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 shielding portion 642A 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 adjusting cover 641 needs to rotate is too large, which is not conducive to the rapid opening and closing of the rotating gate 64; when the angular curvature of the fan-shaped shielding portion 642A is 90°, it is not only conducive to strong wind flowing through, but also conducive to the rapid opening and closing of the rotating gate 64.

[0047] In some embodiments, Figure 5-11As shown, the adjusting cover 641 is arranged on the air inlet side of the gate seat 642, and the baffle assembly 6421 is arranged on the air outlet side of the gate seat 642. In this way, after the rotating gate 64 is completely closed, strong wind blows to the surface of the adjusting cover 641, thereby pressing the adjusting cover 641 against the baffle assembly 6421, further improving the sealing and avoiding air leakage. It is worth mentioning that a sealing strip 6422 is provided on the edge of the second opening 642E. The provision of the sealing strip 6422 can further ensure the air tightness of the rotating gate 64, and it is not easy to leak air after the rotating gate 64 is completely closed. Optionally, the gate seat 642 is provided with a protective net 6423, and the area of ​​the protective net 6423 is equal to the cross-sectional area of ​​the gate seat 642. As shown in FIG. Figure 4 As shown, the protective net 6423 can effectively isolate large items from the outside, thereby preventing the large items from entering the series air duct 632 and damaging related equipment of the air supply unit.
