[0002] Glass is quite common in our daily life and is mostly installed in doors and windows. Glass can also be used to make containers to store items, such as laboratory glass, which is mainly used to store laboratory supplies. It can store solid, liquid and gaseous substances. In laboratory glass production, it mainly includes raw material preparation, melting, molding, cooling and solidification. In order to prevent the high-temperature processed glass from cracking, the molded glass needs to be cooled, so a cooling device is used.

The glass production cooling device of the present invention has a fast cooling speed and uniform cooling, and the cooling water can be recycled to achieve the purpose of saving resources; However, the cooling device in the above application still has some shortcomings during use. For example, the recycling of cooling water will gradually increase the temperature of the cooling water, and the cooling water cannot be cooled again, resulting in poor cooling effect on the glass.

For example, the rapidly cooled glass will become brittle, which will affect the later performance of the glass. It is not convenient to cool the formed glass in multiple stages, thereby reducing the use effect of the cooling device.

[0021] The first rotating rod 7 and the second rotating rod 8 are both connected to the guide roller 9 by welding, and the first rotating rod 7 and the guide roller 9 are connected to each other, and the inside of the guide roller 9 is hollow.

[0022] When using the cooling device for producing laboratory glass to prevent high-temperature cracking, first place the workbench 1 in the corresponding position, ensure the stability of the device during use through the workbench 1, and ensure that the first cooling box 18 and the second cooling box 24 are filled with coolant. When the glass needs to be cooled, the hydraulic rod 32 can be started first, and the hydraulic rod 32 will drive the supporting plate 33 to rise, and the protective plate 34 can be driven to rise through the supporting plate 33, so that the two protective plates 34 can be stored, so that the left and right sides of the mounting plate 11 are open, and then the glass is placed on the guide roller 9, and the drive motor 2 is started. The drive motor 2 will drive the first rotating shaft 3 to rotate, and the outer wall of the first rotating shaft 3 is installed with a first connecting gear 4, and the first connecting gear 4 and the second connecting gear 5 are meshed and connected, so in the first When the rotating shaft 3 rotates, it will drive the first connecting gear 4 to rotate, and then drive the second connecting gear 5 and the second rotating shaft 6 to rotate through the first connecting gear 4, wherein the second rotating shaft 6 and the first rotating rod 7 are connected by a transmission belt, and the first rotating rod 7 and the second rotating rod 8 are connected by a traditional belt, and adjacent second rotating rods 8 are connected by a transmission belt, so when the second rotating shaft 6 rotates, the first rotating rod 7 and the second rotating rod 8 will drive the guide roller 9 to rotate together, so that the guide roller 9 will operate to transport the glass, and the first connecting gear 4 is an incomplete gear, so it will drive the second connecting gear 5 to rotate intermittently, so that the guide roller 9 will operate intermittently, and the glass will be transported at a fixed distance, ensuring that the glass is cooled more evenly.

[0023] Embodiment 2: In this embodiment, it is disclosed that the conveyed glass can be cooled by blowing air to further improve the cooling effect of the glass. By combining the cooling by blowing air and the cooling by absorbing heat, the cooling effect of the glass can be better, and the phenomenon of the glass bursting due to high temperature can be prevented. Figure 3-Figure 4 , Figure 6-Figure 7 and Fig.10 As shown: A partition 10 is fixed above the workbench 1, and a mounting plate 11 is mounted on the partition 10, and a cooling structure capable of absorbing heat from the glass is arranged on the inner side of the mounting plate 11, and the cooling structure includes a fan 12; The fan 12 is fixed on the top of the mounting plate 11 by bolts, and an air suction pipe 13 is installed at the inlet end of the fan 12, and the end of the air suction pipe 13 away from the fan 12 is connected to the first diverter pipe 14, an air inlet pipe 15 is installed at the bottom of the first diverter pipe 14, a first air outlet pipe 16 is installed at the outlet end of the fan 12, and the end of the first air outlet pipe 16 away from the fan 12 is connected to the second diverter pipe 17, and the end of the second diverter pipe 17 away from the first air outlet pipe 16 is communicated with the first cooling box 18, a fixed shaft 19 is connected to the inner bearing of the first cooling box 18, and a fixed blade 20 and a stirring blade 21 are installed on the outer wall of the fixed shaft 19, and the fixed blade 20 and the outlet end of the second diverter pipe 17 are located on the same horizontal line, there is a gap between the stirring blade 21 and the inner wall of the first cooling box 18, and one end of the second air outlet pipe 22 is fixed to the left side of the first cooling box 18, and a third diverter pipe 23 is installed at the bottom end of the second air outlet pipe 22; The fan 12 is started. An air suction pipe 13 is installed at the inlet end of the fan 12. The bottom of the air suction pipe 13 is connected to the first shunt pipe 14. Inlet pipes 15 are installed at the bottom of the first shunt pipe 14. The first shunt pipe 14 and the air inlet pipe 15 are both located on the inner side of the mounting plate 11. Therefore, the heat of the glass during transportation can be absorbed by the first shunt pipe 14 and the air inlet pipe 15, and the heat can enter the first cooling box 18 through the first outlet pipe 16 and the second shunt pipe 17. The inner bearing of the first cooling box 18 is connected to the first cooling box 18. A fixed shaft 19 is connected, and a fixed blade 20 is installed on the outer wall of the fixed shaft 19, and the fixed blade 20 and the outlet end of the second diverter pipe 17 are located on the same horizontal line, so when the second diverter pipe 17 discharges gas, the fixed blade 20 will be driven to rotate, and the fixed shaft 19 will be driven to rotate by the fixed blade 20, so that the stirring blade 21 will be driven to rotate by the fixed shaft 19, so that the stirring blade 21 stirs the coolant in the first cooling box 18, speeds up the cooling speed of the coolant, and effectively prevents the coolant from having a high temperature. A second air outlet pipe 22 is installed on the left side of the first cooling box 18, and a third diversion pipe 23 is installed at the bottom of the second air outlet pipe 22, so that the cooled gas can be discharged from the third diversion pipe 23. Since the third diversion pipe 23 is located on the left side of the mounting plate 11, the transported glass can be cooled by blowing air, thereby further improving the cooling effect of the glass. By combining cooling by blowing air and cooling by heat absorption, the glass can be cooled by a better effect, thereby achieving the purpose of staged cooling of the glass and preventing the glass from cracking due to rapid cooling.

[0024] Embodiment 3: In this embodiment, during the glass conveying process, the glass can be cooled again by the guide roller 9 to improve the cooling progress of the glass. For details, please refer to Figure 5 , Figure 8 , Figure 10-12 : A second cooling box 24 is provided on the right side of the workbench 1, and an air suction pump 25 is installed above the second cooling box 24; The outlet end of the suction pump 25 is connected to the connecting pipe 26, and a conduit 27 is provided on the connecting pipe 26, and one end of the conduit 27 away from the connecting pipe 26 is connected to the first rotating rod 7 and the second rotating rod 8; A sleeve 28 is installed on the inner side of the guide roller 9, and a ball stopper 29 is arranged on the inner side of the sleeve 28. The end of the sleeve 28 connected to the guide roller 9 is open, and the end of the sleeve 28 located on the inner side of the guide roller 9 is porous. The inner wall diameter of the sleeve 28 changes from small to large, and the minimum diameter of the inner wall of the sleeve 28 is smaller than the diameter of the ball stopper 29. A heat dissipation hole 31 is opened on the upper surface of the second cooling box 24, and an exhaust pipe 30 is installed between the inlet end of the suction pump 25 and the second cooling box 24. Because the guide roller 9 is connected with the first rotating rod 7 and the conduit 27, the suction pump 25 on the second cooling box 24 can also be started during the glass conveying process. The suction pump 25 will extract the gas in the second cooling box 24 through the suction pipe 30. The second cooling box 24 is provided with an air inlet. When the air enters the second cooling box 24, it will contact the coolant in the second cooling box 24, so that the gas can be cooled. The suction pipe 30 does not contact the coolant, so that when the suction pump 25 is working, the low-temperature gas can enter the connecting pipe 26, and then enter the first rotating rod 7, the second rotating rod 8 and the guide roller 9 on the rear side through the conduit 27. Because the end of the sleeve 28 located on the inner side of the guide roller 9 is porous, the gas will enter the sleeve 28, and the other end of the sleeve 28 is open. Therefore, when the sleeve 28 rotates with the guide roller 9 and the blocking ball 29 on the inner side of the sleeve 28 does not block the gas outlet end, the gas will be discharged from the open end of the sleeve 28, which will cool the glass. Air blowing is performed for cooling. When the sleeve 28 continues to rotate, that is, when the open end of the sleeve 28 faces downward, the blocking ball 29 will block the open end of the sleeve 28 under the action of gravity, so that the gas will not be discharged. Therefore, when the open end of the sleeve 28 corresponds to the glass, gas will be discharged for cooling. When the open end of the sleeve 28 faces downward and does not correspond to the glass, gas will not be discharged, which effectively reduces the waste caused by gas discharge. In this way, during the glass transportation process, the glass can be cooled again by the guide roller 9 to improve the cooling progress of the glass. The upper surfaces of the first cooling box 18 and the second cooling box 24 are both provided with heat dissipation holes 31, which can speed up the heat dissipation progress of the coolant and prevent the coolant from having a high temperature, thereby achieving a better cooling effect on the glass. By combining the adsorption of heat and the cooling by air blowing, the purpose of cooling the glass in multiple stages can be achieved, and the glass cooling can be more uniform, effectively preventing the glass from bursting due to rapid cooling, thereby completing a series of tasks.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
