Technical Field

[0002] In the field of hot-bent glass processing, the cooling process plays a vital role in the quality and performance of the glass. With the rapid development of industries such as construction, automobiles, and electronics, the demand for hot-bent glass is increasing, and the requirements for its quality and precision are also becoming increasingly higher. After being heated at high temperatures and formed in the mold, hot-bent glass usually needs to be cooled and shaped within the mold to achieve the desired shape and performance.

[0003] Currently, conventional hot-bent glass cooling equipment often fails to effectively control the temperature difference between the glass surface and interior during the cooling process, leading to quality issues such as cracking or cracking due to excessive thermal stress. For example, some equipment uses water cooling directly, causing the glass surface temperature to drop sharply while the interior temperature remains high. This significant temperature difference generates significant thermal stress within the glass, seriously affecting the quality and yield of the glass. Summary of the Invention

[0020] (3) Beneficial effects

[0021] The present invention provides a uniform cooling machine for hot-bending glass processing, which has the following beneficial effects:

[0022] (1) The cooling machine is equipped with a cooling device. When the mold placement rack pushes the hot-bent glass mold into the box, the hot-bent glass mold is located between the upper and lower positioning mechanisms. At this time, the air cooling mechanism filters the outside cold air and sends it into the connecting pipe. Then, the spray assembly in the positioning mechanism blows it simultaneously to the upper and lower sides of the mold, causing the glass surface temperature to drop slowly and relatively evenly. This can effectively reduce the temperature difference between the glass surface and the interior, prevent the generation of large thermal stress due to excessive temperature difference, avoid cracking or bursting of the glass, and ensure the quality and integrity of the glass.

[0023] (2) The cooling machine is provided with an air cooling mechanism, and the flow channel is switched through the guide component in the air cooling mechanism, so that the cooling water in the cooling water tank enters the connecting pipe through the air cooling mechanism, and finally the coolant is sprayed onto the upper and lower surfaces of the mold through the spray component. On the basis of the initial cooling by air cooling, the glass temperature is further quickly reduced, thereby improving the overall cooling efficiency.

[0024] (3) The cooling machine is provided with a positioning mechanism. The injection components in the positioning mechanisms on the upper and lower sides can simultaneously spray the cooling medium from the upper and lower directions of the mold, thereby avoiding problems such as glass deformation and uneven internal stress distribution caused by uneven cooling. The coolant sprayed on the upper and lower sides of the hot-bent glass mold will flow into the return tank through the downpipe and the flow channels on both sides of the support plate respectively. After it is cooled, it can be re-absorbed into the interior of the cooling water tank through the return pipe by the water pump on the top of the cooling water tank, thereby reducing the consumption of coolant.

[0025] (4) The cooler is provided with a guide assembly, and the lifting cylinder contracts, so that the connecting rod drives the annular guide shell to move downward and separate from the surface of the porous baffle. At this time, the side wall of the downward moving annular guide shell can block the opening at the bottom of the connecting pipe, preventing the cooling water in the cooling water tank from entering the air guide tube through the connecting pipe. At the same time, the filtered cold air can flow downward into the connecting pipe through the holes opened on the surface of the porous baffle, thereby preventing the coolant from overflowing during air cooling.

[0026] (5) The cooler is provided with a guide assembly. When the lifting cylinder is extended, the guide column on the top of the annular guide shell will block the holes opened on the surface of the porous baffle, blocking the air flow channel. At the same time, the cooling water tank is connected to the air guide tube through the connecting pipe, avoiding the mixing of air and water at inappropriate times, ensuring the stability of the cooling process, and meeting the diverse process requirements at the same time, improving the adaptability of the equipment to different products.

[0027] (6) The cooling machine is provided with a positioning mechanism. The electric push rod extends and drives the manifold shell to move on the upper and lower sides of the hot-bending glass mold. At this time, the telescopic tube extends synchronously, and the injection assembly moves synchronously with the manifold shell. This can increase the movable stroke of the injection assembly and then expand the coverage range of the ejected medium. This can ensure that the cooling medium can act evenly on all parts of the mold, avoiding the situation of insufficient or excessive local cooling.

[0028] (7) The cooling machine is provided with a spray assembly. As the amount of cooling medium increases, the pressure in the guide cylinder increases, forcing the return spring to be compressed. At this time, the spray cylinder moves upward, and the cooling medium is finally ejected outward through the rectangular spray hole, and then sprayed backward on the mold surface through the guide at the top of the guide cylinder. The high-pressure sprayed cooling medium can impact the mold surface more forcefully, enhance the contact and heat exchange efficiency between the cooling medium and the mold surface, and can take away the heat of the mold and the hot-bent glass more quickly, thereby effectively improving the cooling speed and cooling effect.

[0029] (8) The cooler is equipped with a return spring. When the cooling medium flow rate is high and the pressure is high, the return spring is compressed to a greater extent, the ejection tube rises greatly, the rectangular nozzle opening becomes larger, and the ejection volume increases. Conversely, when the cooling medium flow rate is low and the pressure is low, the return spring is compressed to a lesser extent, the ejection tube rises less, and the ejection volume decreases accordingly. This automatic adjustment function enables the ejection assembly to adapt to different cooling needs and operating conditions, improving the versatility and adaptability of the equipment.

[0030] (IX) The cooling machine is provided with an internal threaded push rod. When the threaded knob is turned, the internal threaded push rod can slide up and down along the surface of the guide column limit frame, thereby adjusting the position of the limit block in the slide groove, so that the maximum movement stroke of the injection tube can be adjusted. The movement stroke of the injection tube determines the maximum opening size of the rectangular spray hole. During the equipment debugging process, the operator can adjust the position of the limit block according to the actual situation to find the most suitable injection amount and cooling effect.

[0031] (10) This cooler incorporates a filter assembly with a porous air inlet hood fixed to the top of a corrugated protective sleeve. External air first enters the filter assembly through the porous air inlet hood. The evenly distributed small holes in the porous air inlet hood provide preliminary air filtration, blocking the entry of larger dust particles and impurities. The corrugated protective sleeve seals the gap between the retaining ring and the porous air inlet hood, preventing cool air from leaking when the porous air inlet hood vibrates.

[0032] (11) The cooling machine is provided with a knocking assembly, and the fixed frame in the knocking assembly rotates together with the driving shaft of the driving motor. At this time, the slider drives the knocking block to move to the side away from the fixed frame through the sliding rod under the action of centrifugal force, and overcomes the elastic force of the compression spring to gradually approach the arc-shaped spring piece. When the speed of the driving motor becomes faster, the knocking block will knock on the surface of the arc-shaped spring piece, which will cause the porous air inlet hood to vibrate, and shake off the dust and impurities attached to the surface of the porous air inlet hood, so that the filter assembly maintains a good filtering effect.

The outer side of the box body 61 is fixedly connected to the top of the frame 1, and the bottom of the cooling water tank 63 is fixedly connected to the top of the box body 61. The bottom ends of the downpipes 67 of the return pipe 64 extend to the inside of the reflux box 7. The top of the connecting pipe 65 is fixedly connected to the bottom of the air cooling mechanism 62, and the outer side of the positioning mechanism 66 is fixedly connected to both sides of the inner wall of the box body 61. When the mold placement rack 4 pushes the hot-bent glass mold into the box body 61, the hot-bent glass mold is just located between the positioning mechanisms 66 on the upper and lower sides. At this time, the air cooling mechanism 62 filters the external cold air and sends it into the connecting pipe 65, and then blows it to the upper and lower sides of the mold at the same time through the injection assembly 663 in the positioning mechanism 66, so that the surface temperature of the glass drops slowly and more evenly. This can effectively reduce the temperature difference between the glass surface and the interior, prevent large thermal stress caused by excessive temperature difference, avoid cracking or bursting of the glass, and ensure the quality and integrity of the glass; after the air cooling is completed, the flow channel is switched through the guide component 626 in the air cooling mechanism 62, so that the cooling water in the cooling water tank 63 enters the connecting pipe 65 through the air cooling mechanism 62, and finally the coolant is sprayed onto the upper and lower surfaces of the mold through the spray component 663, further quickly reducing the glass temperature on the basis of the initial cooling by air cooling, thereby improving the overall cooling efficiency;

[0047] The air cooling mechanism 62 includes an air guide tube 621, the bottom of the air guide tube 621 is fixedly connected to a drive motor 622, the output shaft of the drive motor 622 is fixedly connected to a fan blade 623 and a knocking assembly 625, the top of the air guide tube 621 is fixedly connected to a filter assembly 624, the inner side of the air guide tube 621 is fixedly connected to a flow guide assembly 626, and both sides of the air guide tube 621 are fixedly connected to a connecting pipe 627.

The spray assembly 663 in 66 can spray the cooling medium from the upper and lower directions of the mold at the same time, avoiding the problems of glass deformation and uneven internal stress distribution caused by uneven cooling, which helps to improve the yield and quality of hot-bent glass. In this process, the coolant sprayed on the top of the hot-bent glass mold will fall into the return box 7 through the downpipe 67, while the coolant sprayed below the hot-bent glass mold will flow along the mold placement rack 4 to the support plate 3, and then flow into the return box 7 through the flow channels on both sides of the support plate 3, thereby completing the coolant recovery process. After the coolant is cooled in the return box 7, it can be re-absorbed into the interior of the cooling water tank 63 by the water pump on the top of the cooling water tank 63 through the return pipe 64, thereby reducing the consumption of coolant.

When the air cooling mechanism 62 is working, the driving motor 622 drives the fan blades 623 to rotate, and the external cold air is sucked into the air guide tube 621 through the filter assembly 624. At this time, the lifting cylinder 261 in the guide assembly 626 contracts, so that the connecting rod 262 drives the annular guide shell 263 to move downward and separate from the surface of the porous baffle 264. At this time, the downward moving annular guide shell The side wall of the flow shell 263 can block the opening at the bottom of the connecting pipe 627, preventing the cooling water in the cooling water tank 63 from entering the air guide 621 through the connecting pipe 627. At the same time, the filtered cold air can flow downward through the holes opened on the surface of the porous baffle 264 and enter the connecting pipe 65, thereby preventing the coolant from overflowing during air cooling. When the lifting cylinder 261 is extended, the guide column on the top of the annular guide shell 263 will block the holes opened on the surface of the porous baffle 264, blocking the air flow path.

The evenly distributed small holes in the porous air inlet cover 243 provide preliminary air filtration, blocking larger dust particles and impurities from entering. The corrugated protective sleeve 242 is used to seal between the fixed ring 241 and the porous air inlet cover 243, preventing cold air from leaking when the porous air inlet cover 243 vibrates.

[0052] The knocking assembly 625 includes a fixed frame 251, the inner walls of both sides of the fixed frame 251 are slidably connected with sliders 252, the outer side of the slider 252 is fixedly connected with a sliding rod 253, the outer side of the sliding rod 253 is fixedly connected with a knocking block 255, the outer wall of the sliding rod 253 is fixedly connected to the inner wall of the fixed frame 251, the inner side of the fixed frame 251 is fixedly connected with a compression spring 254, the outer side of the compression spring 254 is fixedly connected to the outer side of the slider 252, the center of the fixed frame 251 is fixedly connected to the output shaft of the drive motor 622, and when the drive motor 622 rotates, the knocking assembly 625 is fixedly connected to the outer side of the slider 252. The fixing frame 251 in the component 625 rotates together with the driving shaft of the driving motor 622. At this time, the slider 252 drives the knocking block 255 to move to the side away from the fixing frame 251 through the sliding rod 253 under the action of centrifugal force, and overcomes the elastic force of the compression spring 254 and gradually approaches the arc-shaped spring piece 244. When the speed of the driving motor 622 becomes faster, the knocking block 255 will knock on the surface of the arc-shaped spring piece 244, which will cause the porous air inlet cover 243 to vibrate, and shake off the dust and impurities attached to the surface of the porous air inlet cover 243, so that the filter component 624 maintains a good filtering effect.

[0053] Working principle:

[0054] When in use, the servo motor inside the frame 1 drives the turntable 2 to rotate intermittently, and the servo motor is kept rotating at an angle of ninety degrees each time, and then the mold with the hot-bent glass is placed on the mold placement rack 4, and the turntable 2 drives the mold placement rack 4 to rotate together through the support plate 3, wherein the mold placement rack 4 is composed of a placement bin and a push plate fixedly connected to its bottom by a guide column. When the mold placement rack 4 with the hot-bent glass is placed rotates to the top of the telescopic cylinder 5, the telescopic cylinder 5 is started, and its top pushes the mold placement rack 4 and the hot-bent glass mold thereon to move upward until the hot-bent glass mold is sent into the box 61 of the cooling device 6 for cooling. After the cooling is completed, the telescopic cylinder 5 contracts, and the mold placement rack 4 can be reset under the action of gravity;

[0055] Among them, four mold placement racks 4 that can move up and down form a multi-station processing mode. This design allows other mold placement bins to perform loading and unloading operations while one mold is cooling, effectively improving production efficiency and realizing continuous production.

[0056] When the mold placement rack 4 pushes the hot-bending glass mold into the box 61, the hot-bending glass mold is located exactly between the upper and lower positioning mechanisms 66. At this time, the air cooling mechanism 62 filters the external cold air and sends it into the connecting pipe 65. Then, the air is blown simultaneously to the upper and lower sides of the mold through the injection assembly 663 in the positioning mechanism 66, causing the glass surface temperature to drop slowly and relatively evenly. This effectively reduces the temperature difference between the glass surface and the interior, prevents the generation of large thermal stress due to excessive temperature difference, avoids cracking or bursting of the glass, and ensures the quality and integrity of the glass.

[0057] After the air cooling is completed, the flow channel is switched through the guide component 626 in the air cooling mechanism 62, so that the cooling water in the cooling water tank 63 enters the connecting pipe 65 through the air cooling mechanism 62, and finally the coolant is sprayed onto the upper and lower surfaces of the mold through the spray component 663, further quickly lowering the glass temperature on the basis of the initial cooling by air cooling, thereby improving the overall cooling efficiency.

[0058] Among them, the injection assembly 663 in the upper and lower adjustment mechanisms 66 can simultaneously spray the cooling medium from the upper and lower directions of the mold, avoiding problems such as glass deformation and uneven internal stress distribution caused by uneven cooling, which helps to improve the yield and quality of hot-bent glass. In this process, the coolant sprayed above the hot-bent glass mold will fall into the reflux box 7 through the downpipe 67, while the coolant sprayed below the hot-bent glass mold will flow along the mold placement rack 4 to the support plate 3, and then flow through the flow channels on both sides of the support plate 3 to the reflux box 7, thereby completing the coolant recovery process. After the coolant is cooled in the reflux box 7, it can be re-absorbed into the interior by the water pump on the top of the cooling water tank 63 through the return pipe 64, thereby reducing the consumption of coolant.

[0059] When the air cooling mechanism 62 is working, the driving motor 622 drives the fan blades 623 to rotate, and the external cold air is sucked into the air guide tube 621 through the filter assembly 624. At this time, the lifting cylinder 261 in the guide assembly 626 contracts, so that the connecting rod 262 drives the annular guide shell 263 to move downward and separate from the surface of the porous baffle 264. At this time, the side wall of the downward moving annular guide shell 263 can block the opening at the bottom of the connecting pipe 627, preventing the cooling water in the cooling water tank 63 from entering the air guide tube 621 through the connecting pipe 627. At the same time, the filtered cold air can flow downward through the holes opened on the surface of the porous baffle 264 and enter the connecting pipe 65, thereby preventing the coolant from overflowing during air cooling.

[0060] When the lifting cylinder 261 is extended, the guide column on the top of the annular guide shell 263 will block the holes opened on the surface of the porous baffle 264, blocking the air flow path. At the same time, the upward moving annular guide shell 263 will also move above the bottom opening of the connecting pipe 627, so that the cooling water tank 63 is connected to the air guide tube 621 through the connecting pipe 627, blocking the water flow channel during air cooling and blocking the air flow channel during water cooling, avoiding the mixing of air and water at inappropriate times, ensuring the stability of the cooling process, meeting diverse process requirements, and improving the adaptability of the equipment to different products.

[0061] When the cooling medium enters the adjustment mechanism 66 through the connecting pipe 65, the electric push rod 664 extends and drives the confluence shell 662 to move on the upper and lower sides of the hot-bending glass mold. At this time, the telescopic tube 661 extends synchronously, and the injection assembly 663 moves synchronously with the confluence shell 662. This increases the movable stroke of the injection assembly 663 and further expands the coverage of the ejected medium. This ensures that the cooling medium can evenly act on all parts of the mold, avoiding the situation of insufficient or excessive local cooling.

[0062] When the cooling medium enters the guide cylinder 301 in the injection assembly 663, as the cooling medium increases, the pressure in the guide cylinder 301 increases, forcing the return spring 303 to be compressed. At this time, the injection cylinder 302 moves upward, and the cooling medium can finally be ejected outward through the rectangular spray hole 309 after passing through the gap between the limit block 307 and the injection cylinder 302. Then, it is guided backward at the top of the guide cylinder 301 and sprayed onto the mold surface. The high-pressure injection of cooling medium can more forcefully impact the mold surface, enhance the contact between the cooling medium and the mold surface and the heat exchange efficiency, and can more quickly remove the heat from the mold and the hot-bent glass, thereby effectively improving the cooling speed and cooling effect.

[0063] The placement of return spring 303 enables injection assembly 663 to automatically adjust the elevation of injection tube 302 based on the coolant flow rate and pressure, thereby controlling the injection volume. When the coolant flow rate and pressure are high, return spring 303 is compressed significantly, causing injection tube 302 to rise significantly, widening the opening of rectangular spray hole 309 and increasing the injection volume. Conversely, when the coolant flow rate and pressure are low, return spring 303 is compressed less, causing injection tube 302 to rise less, and the injection volume is correspondingly reduced. This automatic adjustment function enables injection assembly 663 to adapt to varying cooling requirements and operating conditions, improving the versatility and adaptability of the device.

[0064] When the threaded knob 304 is turned, the internal threaded push rod 306 can slide up and down along the surface of the guide column limit frame 305, thereby adjusting the position of the limit block 307 in the slide groove 308, so that the maximum movement stroke of the injection cylinder 302 can be adjusted. The movement stroke of the injection cylinder 302 determines the maximum opening size of the rectangular spray hole 309. During the equipment debugging process, the operator can adjust the position of the limit block 307 according to the actual situation to find the most suitable injection volume and cooling effect.

[0065] As cold air passes through filter assembly 624, porous air inlet hood 243 is fixed to the top of corrugated protective sleeve 242, and outside air first enters filter assembly 624 through porous air inlet hood 243. The evenly distributed small holes in porous air inlet hood 243 provide preliminary filtration of the air, blocking the entry of larger dust particles and impurities. Corrugated protective sleeve 242 is used to seal between fixed ring 241 and porous air inlet hood 243, preventing cold air from leaking when porous air inlet hood 243 vibrates.

[0066] When the driving motor 622 rotates, the fixing frame 251 in the knocking assembly 625 rotates together with the driving shaft of the driving motor 622. At this time, the slider 252 drives the knocking block 255 to move to the side away from the fixing frame 251 through the sliding rod 253 under the action of centrifugal force, and overcomes the elastic force of the compression spring 254 and gradually approaches the arc-shaped spring piece 244. When the speed of the driving motor 622 becomes faster, the knocking block 255 will knock on the surface of the arc-shaped spring piece 244, which will cause the porous air inlet cover 243 to vibrate, and shake off the dust and impurities attached to the surface of the porous air inlet cover 243, so that the filter assembly 624 maintains a good filtering effect.
