During the production process of tempered glass, the glass needs to be heated to a certain temperature and then cooled to a specified temperature at a certain cooling rate.

[0003] A cooling device is designed in the related technology, which adopts an air cooling method, including a box body, a conveying platform and an air guide hood are arranged in the box body, the air guide hood is horizontally arranged above the conveying platform, and an air inlet is arranged on the side wall of the box body. The heated glass is conveyed by the conveying platform, and gas is continuously conveyed into the box body through the air inlet. The gas is guided by the air guide hood and flows between the conveying platform and the air guide hood. The gas passes through the surface of the glass to achieve cooling of the glass.

[0004] With respect to the above-mentioned related technologies, the air guide hood is horizontally arranged above the conveyor platform. When the gas flows between the air guide hood and the conveyor platform, it is affected by the air resistance.

Therefore, it needs to be improved. Summary of the invention

[0012] By adopting the above technical solution, when the first oil cylinder and the second oil cylinder adjust the air guide hood, the piston rod of the buffer retracts and contracts with the air guide hood, and the buffer can cushion the movement of the air guide hood, thereby improving the stability of the air guide hood before and after adjustment and playing a role in protecting the equipment.

[0013] Optionally, a plurality of first guide plates are provided at the bottom end of the air guide cover, and the length direction of the first guide plates is arranged along the length direction of the air guide cover. A rotating assembly is provided on the air guide cover, and the rotating assembly is used to drive the plurality of first guide plates and the air guide cover to rotate together.

The driving shaft of the first motor is connected to the worm, and the worm and several worm wheels are meshed with each other.

[0016] By adopting the above technical solution, when the inclination angle between the first guide plate and the air guide cover needs to be adjusted, the first motor drives the worm to rotate, the worm and the worm wheel are against each other, and then drives several worm wheels to rotate.

[0017] Optionally, a plurality of through holes are provided on the first guide plate.

[0018] By adopting the above technical solution, when the wind flows on the surface of the wind guide cover, the wind will collide with the first guide plate. At this time, part of the wind will be guided by the first guide plate to move toward the glass surface, and part of the wind will flow through the through hole to the next first guide plate, and so on.

After cooling the upper surface of the glass, the wind collides with the first circulation plate and then moves toward the second circulation plate. The wind collides with the second circulation plate and then moves toward the second guide plate. Since the second guide plate is inclined below the conveying roller, the wind guided by the second guide plate will collide with the lower surface of the glass on the conveying roller to cool the lower surface of the glass. Finally, the cooled wind is discharged through the air outlet. The wind forms a cycle in the box, which can cool the upper and lower surfaces of the glass in turn, effectively utilizing wind energy to achieve the effect of energy saving and emission reduction, while improving the cooling effect on the glass, which is beneficial to improving production and processing efficiency.

When the wind flows from the air inlet to the direction away from the air inlet, the wind pressure gradually decreases. Although the wind is subject to resistance, the wind pressure will not drop too much when the opening gradually decreases, thereby keeping the cooling speed and effect of various parts of the glass surface balanced, improving the balance during cooling, and achieving the effect of improving product quality;

[0027] 2.

Since the second guide plate is inclined below the conveying roller, the wind is guided by the second guide plate and collides with the lower surface of the glass on the conveying roller to cool the lower surface of the glass. Finally, the cooled wind is discharged through the air outlet. The wind forms a cycle in the box and can cool the upper and lower surfaces of the glass in turn, effectively utilizing wind energy to achieve the effect of energy saving and emission reduction.

The first oil cylinder 21 is located at one end of the air guide cover 2 close to the air inlet 11, and the second oil cylinder 22 is located at one end of the air guide cover 2 away from the air inlet 11. The first oil cylinder 21 is fixed to the top wall of the box body 1 by bolts, the piston rod of the first oil cylinder 21 is hinged to the air guide cover 2, the second oil cylinder 22 is hinged to the top wall of the box body 1, and the piston rod of the second oil cylinder 22 is hinged to the air guide cover 2. The piston rods of the first oil cylinder 21 and the second oil cylinder 22 are extended and retracted, so that the air guide hood 2 can be tilted above the conveying roller 31. When cooling the glass, the wind enters the box body 1 through the air inlet 11, and the wind passes between the air guide hood 2 and the conveying roller 31 to cool the glass surface. Through the operation of the first oil cylinder 21 and the second oil cylinder 22, the distance between the end of the air guide hood 2 close to the air inlet 11 and the conveying roller 31 is increased, and the distance between the end of the air guide hood 2 away from the air inlet 11 and the conveying roller 31 is increased.

When the wind flows on the lower surface of the wind guide 2, the wind will collide with the first guide plates 6. Since the bottom end of the first guide plates 6 is arranged above the conveying roller 31, the wind will move toward the glass surface under the guidance of the first guide plates 6, which improves the utilization range of the wind, thereby effectively improving the cooling effect on the glass. A plurality of through holes 61 are arranged through the first guide plates 6, and the number of through holes 61 decreases successively on the first guide plates 6 away from the air inlet 11.
