[0002] Air-cooling units in glass tube production lines play a crucial role in the glass production process, which involves multiple steps such as high-temperature melting, forming, and cooling of glass raw materials. Temperature control and cooling efficiency significantly impact glass quality and production efficiency. Air-cooling units in glass tube production lines offer substantial advantages in improving cooling efficiency, ensuring product quality, and energy conservation and environmental protection. With continuous technological advancements, the design and application of air-cooling units will become more sophisticated, providing more efficient and environmentally friendly solutions for glass production.

[0003] While existing technologies use cooling devices to cool high-temperature glass to create prestress and improve its strength and impact resistance, the cooling effect of single air cooling and water cooling is not uniform, causing thermal stress concentration in some parts of the glass tube. This results in some parts of the glass tube not meeting the hardness standard, affecting the yield. At the same time, the traditional method is to air cool and dry the glass after water cooling, which makes it easy to leave water stains on the glass surface, affecting the aesthetics of the glass tube production and subsequent processing and treatment.

[0017] An air-cooling method for an air-cooling device used in a glass tube production line includes the following steps:

[0018] S1. First, after the glass tube is produced, it is conveyed to the top of the fixed frame. The side wall of the glass tube is contacted by the conveyor rollers. The electrically driven transmission pulley rotates, which drives the first driven pulley to rotate. Since another set of belts is provided, it will drive multiple sets of second driven pulleys to rotate, thereby causing the conveyor rollers to rotate. At this time, the glass tube is conveyed forward.

[0019] S2. During the forward conveying of the glass tube, the second telescopic rod extends to bring the rotating wheel into contact with the surface of the glass tube, and the rotating wheel rotates under electric drive, causing the glass tube to rotate synchronously during the forward conveying process;

[0020] S3. During the conveying process, the water in the tank will be pumped through the connecting pipe and spray pipe and sprayed out by the atomizing nozzle. The atomized water mist will fall on the surface of the glass tube after being sprayed out by the atomizing nozzle. The volume of water sprayed out is monitored by the flow sensor. At this time, the surface of the glass tube will be initially cooled. The rotation conveying and water mist spraying are synchronized, and the positioning accuracy is 0.02mm.

[0021] S4. As the glass tube undergoes initial cooling and continues to be conveyed forward, the second motor drives the rotating rod to rotate, causing the first motor to move in a circular motion under the action of the first and second rotating frames. Simultaneously, the first motor drives the fan blades to rotate, and the fan blades move in a spiral trajectory, blowing high-speed airflow onto the surface of the glass tube. This thoroughly dries the moisture on the surface of the glass tube and rapidly removes heat from the surface of the glass tube through the evaporation of moisture, achieving air cooling.

[0022] S5. After the glass tube is cooled by air, it enters the sleeve and passes through two curved plates. At this time, under the action of the spring, the curved plates are in contact with the surface of the glass tube, and the wiping sponge on the inner wall of the curved plates is used to wipe the residual moisture and debris on the surface of the glass tube. The temperature of the glass tube surface is monitored in real time by the infrared temperature measurement module to achieve cleaning of the glass tube.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. In this invention, during the forward conveying of the glass tube, a rotating device causes the glass tube to rotate synchronously during the conveying process, enabling the glass tube to rotate on its own axis. A second motor drives a rotating rod to rotate, causing the first motor to move in a ring under the action of the first and second rotating frames. Simultaneously, the first motor drives the fan blades to rotate, blowing high-speed airflow onto the surface of the glass tube, thus achieving spiral airflow. This spiral airflow falls on the surface of the self-rotating glass tube, avoiding cooling dead zones and improving the uniformity of cooling of the glass tube. It solves the quality problems caused by uneven air cooling leading to thermal stress concentration, such as substandard hardness and brittleness of the glass tube. Compared with the traditional direct-blowing method, it increases the yield by 5%-10%.

[0025] 2. In this invention, by setting up a conveying device, an atomizing device, and a rotating device, water flows through a connecting pipe and a spray pipe and is sprayed out by an atomizing nozzle, so that the atomized water mist falls on the surface of the glass tube to cool the glass tube. At this time, the rotating device drives the glass tube to rotate axially during the conveying process, so that the surface of the glass tube is evenly wetted by the mist. At the same time, a spiral blower is used to make the water mist on the surface of the glass tube after spraying evaporate quickly and take away the heat. By combining the spiral blower, the rotation of the glass tube and the atomizing spray, the surface of the glass tube is further cooled in all directions and evenly, so as to improve the yield rate by 5%-10%.

[0026] 3. In this invention, by setting up a wiping device, the glass tube is cooled and enters the sleeve, passing through two arc-shaped plates. At this time, under the action of the spring, the arc-shaped plates are tightly attached to the surface of the glass tube. The wiping sponge is used to wipe away the residual water and debris on the surface of the glass tube, thus cleaning the glass tube. Through the cooperation of the elastic component and the wiping sponge, the residual water stains and debris on the surface of the glass tube can be effectively removed, preventing water stains and debris from adhering to the surface of the glass tube and adding scratches to the surface of the glass tube. The removal rate can reach 98%, which solves the technical problem of water stains affecting the aesthetics of the glass tube and protecting the integrity of the glass tube surface. Moreover, after wiping away water stains, the subsequent packaging and other processes are significantly improved, increasing the work efficiency of the subsequent processes by 20%.

[0040] The conveying device 2 is also equipped with a rotating device 5 for rotating the glass tube itself when the cooling device 1 cools the glass tube. The rotating device 5 includes a second telescopic rod 501. The movable end of the second telescopic rod 501 is fixedly connected to a mounting plate 502. The top of the mounting plate 502 has a number of mounting frames 504 arranged in a linear array. A fourth motor 505 is fixedly connected to one side of each of the mounting frames 504. A rotating wheel 503 is rotatably connected to the inner side wall of each of the mounting frames 504. The fixed end of the second telescopic rod 501 is fixedly connected to the middle of the fixed frame 202.

[0041] Several second driven pulleys 206 are connected by belts on their sidewalls, and the transmission pulley 203 is connected to the sidewall of the first driven pulley 205 by belts. The output end of the third motor 201 is fixedly connected to the middle of the transmission pulley 203. Several conveying rollers 204 are tapered roller shaft structures.

[0042] Two spray pipes 304 are fixedly connected to the front side of the inner wall of the housing 101. The other ends of two connecting pipes 303 pass through both sides of the housing 101 and communicate with the inside of the two spray pipes 304. Several atomizing nozzles 305 are respectively connected to the inside of the two spray pipes 304. One end of the two connecting pipes 303 passes through the pump 302 and communicates with the inside of the water tank 301.

[0043] The output ends of several fourth motors 505 are respectively fixedly connected to the middle of the rotating wheel 503 through the mounting frame 504. The axes of the rotating wheels 503 and the conveying rollers 204 are perpendicular to each other, and the rotating wheels 503 and the conveying rollers 204 are staggered.

[0044] By setting up a conveying device 2, an atomizing device, and a rotating device 5, water flows through a connecting pipe 303 and a spray pipe 304 and is sprayed out by an atomizing nozzle 305, so that the atomized water mist falls on the surface of the glass tube to cool the glass tube. At this time, the rotating device 5 drives the glass tube to rotate axially during the conveying process, so that the surface of the glass tube is evenly wetted by the mist. At the same time, a spiral blower is used to make the water mist on the surface of the glass tube after spraying evaporate quickly and take away the heat.

[0045] By setting up a conveying device 2, an atomizing device 3, and a rotating device 5, after the glass tube is formed, it is conveyed to the top of the fixed frame 202 and contacts the conveying roller 204. The third motor 201 is then turned on, driving the transmission pulley 203 to rotate. This, in turn, drives the first driven pulley 205 to rotate under the belt drive.

During the forward conveying process, the water in the water tank 301 will be sprayed out by the atomizing nozzle 305 through the connecting pipe 303 and the spray pipe 304 under the action of the pump 302, so that the atomized water mist falls on the surface of the glass tube to cool the glass tube. During the glass tube conveying process, the second telescopic rod 501 is extended so that the rotating wheel 503 contacts the bottom surface of the glass tube, and the fourth motor 505 is turned on to drive the rotating wheel 503 to rotate, so that the surface of the glass tube is evenly wetted by the mist, thus achieving the initial cooling of the glass tube.

[0046] Example 2

[0047] like Figure 1 , Figure 2 , Figure 6 - Figure 8 As shown, the present invention provides an air-cooling device for a glass tube production line, including a cooling device 1, a conveying device 2, and a rotating device 5. The conveying device 2 is disposed inside the cooling device 1. The rotating device 5, which is used to complete the rotation of the glass tube itself when the cooling device 1 cools the glass tube, is disposed inside the conveying device 2. The cooling device 1 includes a housing 101. A plurality of air-cooling components for spiral blowing air onto the surface of the glass tube are linearly arrayed on the inner side wall of the housing 101. The air-cooling components include a fixing plate 102. The bottom end of the fixing plate 102 is provided with an air-cooling drive mechanism for driving the spiral blowing air of the air-cooling components. The air-cooling drive mechanism includes... The system includes a first motor 104, a second motor 107, a first rotating frame 103, a rotating rod 105, and a second rotating frame 1010. The second motor 107 is located at the bottom end of the fixed plate 102. The first motor 104 is located below the second motor 107. The first rotating frame 103 is fixedly connected to the side wall of the second motor 107. The rotating rod 105 is connected to the second motor 107. The second motor 107 is connected to the first motor 104 through the rotating rod 105. The lower part of the inner side wall of the first rotating frame 103 is rotatably connected to the second rotating frame 1010.

[0048] The air-cooling assembly also includes a fan blade 109 that provides a blowing function, a vent pipe 106, and a filter screen 108. The fan blade 109 is located at the output end of the first motor 104, the vent pipe 106 is located at the lower end of the first motor 104, and the bottom end of the inner side wall of the vent pipe 106 is fixedly connected to the filter screen 108.

[0049] The rear end of the conveying device 2 is equipped with a wiping device 4 for elastically adhering to the surface of the glass tube and completing the wiping action of water stains on the surface of the glass tube. The wiping device 4 includes an elastic component and a wiping sponge 406 that adheres to the surface of the glass tube through the elastic component. The elastic component includes a support plate 402. A first telescopic rod 401 is fixedly connected to the rear side of the top of the support plate 402. A sleeve 403 is fixedly connected to the movable end of the first telescopic rod 401. Several springs 404 are linearly arrayed at the top and bottom of the inner side wall of the sleeve 403. Two arc-shaped plates 405 are fixedly connected to the other end of the several springs 404. The bottom ends of the inner side walls of the two arc-shaped plates 405 are fixedly connected to the wiping sponge 406. The support plate 402 is fixedly connected to the rear end of the fixing frame 202. The wiping sponge 406 is made of polyvinyl alcohol sponge.

[0050] The output end of the second motor 107 is fixedly connected to one end of the rotating rod 105, the second rotating frame 1010 is rotatably connected to the middle of the first motor 104, and the inner side wall of the first rotating frame 103 is rotatably connected to the middle of the side wall of the second rotating frame 1010.

[0051] It should be noted that the existing air-cooling equipment for glass tube production uses air-cooling and water-cooling processes such as direct air blowing and water mist spraying. However, the direct blowing method cannot achieve uniform cooling of the glass tube, resulting in a large difference in cooling rate in different parts of the glass tube. Uneven cooling speed in different parts will cause thermal stress concentration inside, making the glass tube brittle and fragile, affecting the yield of glass tubes. Uniform cooling can eliminate residual stress.

[0052] During the production process, 1000 glass tubes were selected for comparative experiments using direct blowing cooling and spiral blowing cooling respectively. The following data were obtained: Under direct blowing cooling, with air speeds of 15m / s, 20m / s, and 10m / s and a cooling time of 5 minutes, the yield rates were 83%, 87%, and 81%, respectively. Under spiral blowing cooling, with spiral angles of 30 degrees, 45 degrees, and 69 degrees, air speeds of 15m / s, 20m / s, and 10m / s and a cooling time of 5 minutes, the yield rates were 88%, 96%, and 92%, respectively. Compared with the traditional direct blowing method, the yield rate was improved by 5%-10%. It can be seen that the yield rate is low under direct blowing cooling, while the spiral blowing method improves the yield rate of glass tube production by providing uniform heat dissipation to the surface of the glass tube.

[0053] During the forward transport of the glass tube, the rotating device 5 causes the glass tube to rotate synchronously during transport, making the glass tube rotate on its own axis. The second motor 107 drives the rotating rod 105 to rotate, causing the first motor 104 to move in a ring under the action of the first rotating frame 103 and the second rotating frame 1010. At the same time, the first motor 104 drives the fan blade 109 to rotate, which can blow high-speed airflow onto the surface of the glass tube, thereby realizing spiral airflow. The spiral airflow falls on the surface of the self-rotating glass tube, avoiding the existence of cooling dead zones, improving the uniformity of the glass tube's cooling by airflow, and solving the quality problems such as the glass tube's hardness not meeting the standard and becoming brittle and fragile due to the concentration of thermal stress caused by uneven air cooling. Compared with the traditional direct blowing method, the yield rate is increased by 5%-10%.

[0054] By setting up a wiping device 4, the glass tube is cooled and enters the sleeve 403, passing through two arc-shaped plates 405. At this time, under the action of the spring 404, the arc-shaped plates 405 are tightly attached to the surface of the glass tube. The wiping sponge 406 is used to wipe away the residual water and debris on the surface of the glass tube, thus cleaning the glass tube. Through the cooperation of the elastic component and the wiping sponge 406, the residual water stains and debris on the surface of the glass tube can be effectively removed, preventing water stains and debris from adhering to the surface of the glass tube and adding scratches to the surface of the glass tube. The removal rate can reach 98%, which solves the technical problem of water stains affecting the aesthetics of the glass tube and protecting the integrity of the glass tube surface. Moreover, after wiping the water stains, the subsequent packaging and other processes are significantly improved, increasing the work efficiency of the subsequent processes by 20%.

[0055] By setting up a cooling device 1 and a wiping device 4, when the glass tube is initially cooled and continues to be conveyed forward, the second motor 107 is turned on to drive the rotating rod 105 to rotate, so that the first motor 104 moves in a circle under the action of the first rotating frame 103 and the second rotating frame 1010. At the same time, the first motor 104 drives the fan blade 109 to rotate, which can blow high-speed airflow to the surface of the glass tube, dry the moisture on the surface of the glass tube, and use the evaporation of moisture to quickly remove the heat from the surface of the glass tube, thus achieving air cooling. Finally, the glass tube enters the sleeve 403 and passes through two arc-shaped plates 405. At this time, under the action of the spring 404, the arc-shaped plates 405 are in close contact with the surface of the glass tube. The wiping sponge 406 is used to wipe the residual moisture and debris on the surface of the glass tube, thus cleaning the glass tube.

[0056] Example 3

[0057] like Figure 1 - Figure 8 As shown, the present invention provides an air-cooling method for an air-cooling device used in a glass tube production line, comprising the following steps:

[0058] S1. First, after the glass tube is produced, it is conveyed to the top of the fixed frame 202. The side wall of the glass tube is contacted by the conveying roller 204. The electrically driven transmission pulley 203 rotates, which drives the first driven pulley 205 to rotate. In addition, due to the presence of another set of belts, multiple sets of second driven pulleys 206 will rotate, thereby causing the conveying roller 204 to rotate. At this time, the glass tube is conveyed forward.

[0059] S2. During the forward conveying of the glass tube, the second telescopic rod 501 is extended so that the rotating wheel 503 contacts the surface of the glass tube, and the rotating wheel 503 rotates under the drive of the fourth motor 505, so that the glass tube rotates synchronously during the forward conveying process;

[0060] S3. During the conveying process, the water in the water tank 301 will be pumped by the pump 302, and then sprayed through the connecting pipe 303 and the spray pipe 304 and sprayed out by the atomizing nozzle 305. The atomized water mist will fall onto the surface of the glass tube after being sprayed out by the atomizing nozzle 305. The volume of water sprayed out is monitored by a flow sensor (existing technology will not be described in detail here). At this time, the surface of the glass tube will be initially cooled. The rotation conveying and water mist spraying actions are synchronized, and the positioning accuracy reaches 0.02mm.

[0061] S4. When the glass tube is initially cooled and continues to be conveyed forward, the second motor 107 will drive the rotating rod 105 to rotate, causing the first motor 104 to move in a ring under the action of the first rotating frame 103 and the second rotating frame 1010. At the same time, the first motor 104 drives the fan blade 109 to rotate. At this time, the movement trajectory of the fan blade 109 is spiral, blowing high-speed airflow to the surface of the glass tube, drying the moisture on the surface of the glass tube in all directions, and using the evaporation of moisture to quickly remove the heat from the surface of the glass tube. The temperature of the glass tube surface is monitored in real time by an infrared temperature measurement module (existing technology will not be described in detail), realizing air cooling heat dissipation.

[0062] S5. After the glass tube is cooled by air, it enters the sleeve 403. The glass tube will pass through two arc-shaped plates 405. At this time, under the action of the spring 404, the arc-shaped plates 405 are in contact with the surface of the glass tube, and the wiping sponge 406 on the inner wall of the arc-shaped plates 405 is used to wipe away the residual moisture and debris on the surface of the glass tube, thus cleaning the glass tube.

5. A method for air cooling of an air-cooling device for a glass tube production line according to any one of claims 1-4, characterized in that: Includes the following steps: S1. First, after the glass tube is produced, it is conveyed to the top of the fixed frame (202). The side wall of the glass tube is contacted by the conveying roller (204). The electrically driven transmission pulley (203) rotates. The transmission pulley (203) drives the first driven pulley (205) to rotate. And because another set of belts is provided, it will drive multiple sets of second driven pulleys (206) to rotate, thereby causing the conveying roller (204) to rotate. At this time, the glass tube is conveyed forward. S2. During the forward conveying of the glass tube, the second telescopic rod (501) is extended so that the rotating wheel (503) contacts the surface of the glass tube. The rotating wheel (503) rotates under electric drive, so that the glass tube rotates synchronously during the forward conveying process. S3. During the conveying process, the water in the water tank (301) will be sprayed out through the connecting pipe (303) and the spray pipe (304) by the atomizing nozzle (305) under the action of the pump (302). The atomized water mist will fall on the surface of the glass tube after being sprayed out of the atomizing nozzle (305). At this time, the surface of the glass tube will be initially cooled, and the rotation conveying and water mist spraying are synchronized, with a positioning accuracy of 0.02mm. S4. When the glass tube is initially cooled and continues to be conveyed forward, the second motor (107) will drive the rotating rod (105) to rotate, so that the first motor (104) moves in a circle under the action of the first rotating frame (103) and the second rotating frame (1010). At the same time, the first motor (104) drives the fan blade (109) to rotate. At this time, the movement trajectory of the fan blade (109) is spiral, blowing high-speed airflow to the surface of the glass tube, drying the moisture on the surface of the glass tube, and using the evaporation of moisture to take away the heat from the surface of the glass tube, thus achieving air cooling. S5. After the glass tube is cooled by air, it enters the sleeve (403). The glass tube will pass through two arc plates (405). At this time, under the action of the spring (404), the arc plate (405) is in contact with the surface of the glass tube, and the wiping sponge (406) on the inner wall of the arc plate (405) is used to wipe away the residual moisture and debris on the surface of the glass tube, thereby cleaning the glass tube.
