[0031] A glass conveying roller 7 is installed inside the workbench 2. A glass tempering furnace 4, a glass preheating furnace 5 and a glass cooling furnace 6 are fixedly installed on the upper end of the workbench 2. A cooling water pipe 15 is fixedly connected to the glass tempering furnace 4 and the glass cooling furnace 6.

[0033] The upper end of the cooling water tank 3 is fixedly connected to a first drive motor 11 , an output end of the first drive motor 11 is fixedly connected to a rotating shaft 12 , the rotating shaft 12 is rotatably connected to the cooling water tank 3 , and a spiral stirring blade 13 is fixedly connected to the surface of the rotating shaft 12 .

[0034] A detachable glass residue collection box 8 is installed at the upper end of the base 1, and two fixed brackets 19 are fixedly connected to the lower end of the workbench 2. The surface of the fixed bracket 19 on the right is fixedly connected to a second drive motor 20, and the output end of the second drive motor 20 is fixedly connected to a threaded rod 21, which is rotatably connected to the two fixed brackets 19, and a fixed rod 22 is fixedly connected to the opposite surfaces of the two fixed brackets 19.

A scraper 24 is fixedly connected to the end of the movable plate 23 close to the glass conveying roller 7.

[0035] When using the device, first place the cut glass into the glass preheating furnace 5, start the glass conveying roller 7 to convey the glass, and at the same time start the glass tempering furnace 4 to heat it, start the fan to convey the hot air inside the glass tempering furnace 4 to the inside of the glass preheating furnace 5 to heat the glass, so as to preheat the glass. The glass conveying roller 7 conveys the glass to the inside of the glass tempering furnace 4 to heat the glass. After the heating of the glass is completed, the glass is conveyed to the glass cooling furnace 6 by the glass conveying roller 7 to cool it.

[0036] Since more heat is required in the glass tempering process, the glass tempering furnace 4 may be affected when the device is used for a long time. The water pump 14 is started to pump the water in the cooling water tank 3 from the connecting water pipe 17 to the cooling water pipe 15 to cool the glass preheating furnace 5 and the glass cooling furnace 6. The cooling water in the cooling water pipe 15 is re-injected into the cooling water tank 3 to circulate the cooling water, so as to facilitate preheating and recovery of the device.

[0037] The glass is cooled inside the glass cooling furnace 6, and the cooling fan 25 is started to circulate the air inside the glass cooling furnace 6 to facilitate cooling the glass.

[0038] The first driving motor 11 is started to drive the rotating shaft 12 to rotate, and the rotating shaft 12 drives the spiral stirring blade 13 to rotate, so as to stir the cooling water inside the cooling water tank 3 and improve the uniformity of the cooling water temperature.

[0039] When the cooling water inside the cooling water tank 3 cools the device for a long time, the water temperature will rise. Hot water is pumped out to the outside at the connecting water pipe 17 to facilitate the recovery of waste heat. When the cooling water temperature inside the cooling water tank 3 is too high and boils, the water vapor is discharged through the exhaust pipe 18 for utilization.

[0040] When the device is used for a long time, some impurities may adhere to the surface of the glass conveying roller 7, which may adhere to the glass surface during the tempering process and affect the quality of the glass.

[0042] The cooling water in the cooling water tank 3 is stirred by the movable plate 23, so that the water temperature of the cooling water is evenly distributed, thereby improving the stirring effect of the cooling water.

[0043] By scraping away impurities on the surface of the glass conveying roller 7 with the scraper 24, it is possible to prevent impurities from adhering to the glass surface and causing the quality of the glass to be reduced, thereby improving the quality of the glass.

The glass conveying roller 7 conveys the glass to the inside of the glass tempering furnace 4 to heat the glass. After the heating of the glass is completed, the glass is conveyed to the glass cooling furnace 6 by the glass conveying roller 7 for cooling.

[0045] Since more heat is required in the glass tempering process, the glass tempering furnace 4 may be affected when the device is used for a long time. The water pump 14 is started to pump the water in the cooling water tank 3 from the connecting water pipe 17 to the cooling water pipe 15 to cool the glass preheating furnace 5 and the glass cooling furnace 6. The cooling water in the cooling water pipe 15 is re-injected into the cooling water tank 3 to circulate the cooling water, so as to facilitate preheating and recovery of the device.

[0046] The glass is cooled inside the glass cooling furnace 6, and the cooling fan 25 is started to circulate the air inside the glass cooling furnace 6 to facilitate cooling the glass.

[0047] The first driving motor 11 is started to drive the rotating shaft 12 to rotate, and the rotating shaft 12 drives the spiral stirring blade 13 to rotate, so as to stir the cooling water inside the cooling water tank 3 and improve the uniformity of the cooling water temperature.

[0048] When the cooling water inside the cooling water tank 3 cools the device for a long time, the water temperature will rise. Hot water is pumped out to the outside at the connecting water pipe 17 to facilitate the recovery of waste heat. When the cooling water temperature inside the cooling water tank 3 is too high and boils, the water vapor is discharged through the exhaust pipe 18 for utilization.

[0049] When the device is used for a long time, some impurities may adhere to the surface of the glass conveying roller 7, which may adhere to the glass surface during the tempering process and affect the quality of the glass. At this time, the second drive motor 20 is started to drive the threaded rod 21 to rotate, and the threaded rod 21 drives the movable plate 23 to slide on the surface of the fixed rod 22. The movable plate 23 drives the scraper 24 to scrape the surface of the glass conveying roller 7 to scrape off the impurities on the surface of the glass conveying roller 7, and the impurities are collected using the glass residue collection box 8 to facilitate the use of the device.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
