Description

Technical Field

[0001] The utility model relates to the field of glass transportation, in particular to a transportation device for a tempered glass production line. Background Art

[0002] Glass tempering furnaces currently in use typically consist of a loading station, heating section, cooling section, and unloading station. Glass sheets are carried by conveyor rollers through these sections, sequentially passing through them. The glass to be processed is loaded onto the loading station, heated in the heating section, tempered and cooled in the cooling section, and finally unloaded from the unloading station. Glass is fragile, so proper protection is essential to ensure that glass products arrive intact at their destination.

[0003] Prior art CN202021515257.8 discloses a conveyor roller for the heating section of a glass tempering furnace. The conveyor roller comprises a ceramic roller and metal sleeves at both ends. A high-temperature rope is wound around the ceramic roller, tightly wrapped around the surface of the ceramic roller. Although this utility model can achieve flexible contact between the glass and the ceramic roller by wrapping the high-temperature rope around the ceramic roller, thus avoiding hard friction between the glass and the ceramic roller, the following problems still exist:

[0004] 1. Although the high-temperature rope of this utility model can reduce the direct friction between the glass and the ceramic roller, the high-temperature rope may wear or break when used in a high-temperature environment for a long time and needs to be replaced regularly, which increases maintenance costs.

[0005] 2. The glass of the utility model can only wait for the glass to cool down automatically during the transportation process, which takes a long time to cool down and affects the production efficiency.

[0006] 3. In existing production lines, the glass inspection device is usually set up separately after the conveying device. There is no inspection method for the finished glass on the conveying device, which means that the quality of the glass cannot be monitored in real time during the entire conveying process. This separate setting not only increases the length of the production line, but also may lead to delayed problem detection and affect production efficiency. Utility Model Content

[0007] In view of this, the purpose of the present invention is to provide a conveying device for a tempered glass production line. By combining a hollow structure conveying roller with an air cooling device, the glass can be evenly cooled, the cooling speed during the tempering process is accelerated, and the production efficiency is improved; and the detection device arranged on the conveying frame can monitor the quality of the glass in real time, simplifying the production process and improving production efficiency.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Provided is a conveying device for a tempered glass production line, comprising: a conveying frame, conveying rollers, an air cooling device, and a detection device, wherein the conveying rollers are arranged at intervals on the conveying frame, and the conveying rollers are provided with high-temperature barriers for preventing direct contact between the glass and the conveying rollers;

[0010] The conveying roller is a hollow cylinder, the end of which is connected to the air outlet of the air cooling device through a rotary joint, and air holes are evenly spaced on the conveying roller. The detection device is arranged on the conveying frame between adjacent conveying rollers and can detect the glass passing over it.

[0011] It should be noted that the conveyor frame supports the entire conveying system, including conveyor rollers and other components, providing a stable support foundation for the entire conveying system. The high-temperature barrier can reduce the wear caused by direct contact between the glass and the conveyor roller. The high-temperature barrier is provided on the conveyor roller, which can not only protect the glass but also reduce the wear of the conveyor roller; the conveyor roller is a hollow cylinder, which is connected to the air outlet of the air cooling device through a rotary joint. There are air holes on the conveyor roller for evenly distributing the cooling air flow to the bottom of the glass. The cold air generated by the cooling fan is sent into the interior of the conveyor roller through the ventilation duct and the rotary joint, and then discharged from the air hole to form a cooling air flow for the tempered glass. The cooling air flow can not only cool the tempered glass passing over the conveyor roller, accelerate the cooling of the tempered glass, and improve work efficiency, but also reduce the temperature of the conveyor roller and the high-temperature barrier, reduce the impact of the high temperature of the glass on its conveyor roller, thereby extending the service life of the conveyor roller and the high-temperature barrier.

[0012] Preferably, the air cooling device includes a cooling fan and an air filter. The cooling fan is arranged on the conveying frame. The air filter is arranged at the air outlet of the cooling fan, and its two ends are respectively connected to the cooling fan and the conveying roller.

[0013] It should be noted that the cooling fan generates cold air, and the air filter is used to purify the cold air generated by the cooling fan, thereby improving the cleanliness of the cooling air, reducing the impact of impurities in the air on the tempered glass, and avoiding impurities adhering to the glass.

[0014] Preferably, the air cooling device further comprises a flow control valve, and the flow control valve is provided on the connecting pipeline between the cooling fan and the conveying roller.

[0015] It should be noted that the flow control valve can adjust the amount of cooling air delivered from the cooling fan to the inside of the conveyor roller. By adjusting the opening of the flow control valve, the amount of cooling air entering the conveyor roller can be controlled, and then the speed and intensity of the cooling air flow can be controlled. By precisely controlling the cooling air volume, it can be ensured that the glass reaches the required cooling degree in the shortest time, speeding up the production process.

[0016] Preferably, the high-temperature barrier is a high-temperature rope spirally wound on the outer wall of the conveying roller and / or a high-temperature buffer ring sleeved on the conveying roller at intervals.

[0017] It should be noted that the high-temperature barrier can reduce the direct contact between the glass and the conveyor roller, thereby reducing the risk of wear and damage. The high-temperature rope is spirally wound around the outer wall of the conveyor roller to form a protective layer, so that the glass does not directly contact the conveyor roller, reducing friction and wear. Moreover, the high-temperature rope is usually softer and easier to replace. When it is worn or damaged, it can be easily replaced with a new high-temperature rope; the high-temperature buffer ring can provide a buffering effect for the glass, reduce the impact force caused by direct contact, provide more stable support for the glass, and reduce vibration.

[0018] Preferably, the conveying frame includes a first conveying section and a second conveying section, a high-temperature rope is spirally wound on the conveying rollers on the first conveying section, and high-temperature buffer rings are arranged at intervals on the conveying rollers of the second conveying section. The detection device is arranged on the second conveying section and is located at an end away from the first conveying section.

[0019] It should be noted that the first conveying section refers to the conveying rack near one end of the glass production device. The high-temperature rope is suitable for scenarios that require higher flexibility and more frequent replacement. Therefore, the high-temperature rope is set on the first conveying section (the conveying section where the glass has just left the heating section), and the high-temperature buffer ring is suitable for scenarios that require higher stability and longer service life. Therefore, the high-temperature buffer ring is set on the second conveying section (the rear end of the conveying rack). The high-temperature buffer ring helps to further stabilize the position of the glass and reduce glass movement or damage caused by vibration or impact, especially when the glass is close to completely cooled, the buffer ring can ensure that the glass passes through the detection device smoothly; the combined use of high-temperature ropes and high-temperature buffer rings can provide different protection measures at different stages of transportation to adapt to the needs of glass in different cooling stages.

[0020] Preferably, a crossbeam is provided on the conveying frame between the adjacent conveying rollers, and upward-facing universal wheels are provided at intervals on the crossbeam, and the vertices of the universal wheels and the vertices of the conveying rollers are located on the same plane.

[0021] It should be noted that the setting of universal wheels helps to ensure smooth transition of glass during transportation, especially between conveyor rollers, reducing vibration or deviation of glass caused by gaps between conveyor rollers. The smooth transportation process helps to improve the overall efficiency of the production line, reduce pauses caused by adjusting the position of glass, and improve production efficiency.

[0022] Preferably, the detection device is a high-brightness light board, which is arranged coaxially with the conveying roller across the conveying frame and can illuminate the glass passing over it.

[0023] It should be noted that the high-brightness light board in the detection device spans the conveyor frame and is set coaxially with the conveyor roller to ensure that the light can be evenly irradiated on the glass during transportation. When the glass passes under the high-brightness light board, the light emitted by the light board will illuminate the glass, so that the operator can more accurately identify defects or flaws on the glass surface. By directly irradiating during the conveying process, real-time detection can be achieved without transferring the glass to a special inspection area, which simplifies the production process, and can detect problems more quickly and adjust the production line in time, thereby improving overall production efficiency.

[0024] Preferably, the detection device includes a detection light, an image acquisition unit and a data analysis module. The detection light and image acquisition unit are arranged on the conveying frame and are respectively located on the upper and lower sides of the glass. The data analysis module is arranged on one side of the conveying frame and is electrically connected to the image acquisition unit and can process the image data collected by the image acquisition unit.

[0025] It should be noted that the detection lights and image acquisition unit are respectively arranged on the upper and lower sides of the glass. The detection lights provide sufficient lighting to ensure that the features of the glass surface are clearly visible, helping the image acquisition unit to capture high-quality image data; the image acquisition unit captures the image of the glass surface and sends it to the data analysis module for automatic analysis (computer vision algorithms can be used to identify defects on the glass surface), realizing real-time monitoring of the quality of tempered glass during the transportation process, and improving the automation level and production efficiency of the production line.

[0026] Beneficial effects of the utility model:

[0027] The utility model provides a conveying device for a tempered glass production line, which effectively reduces direct contact between the glass and the conveying rollers by arranging high-temperature barriers (such as high-temperature ropes or high-temperature buffer rings) on the conveying rollers, thereby reducing the risk of wear and damage; the hollow-structured conveying rollers are combined with air cooling devices to evenly cool the glass, accelerate the cooling speed during the tempering process, and improve production efficiency; the integrated detection device (including a high-brightness light board, a detection light, an image acquisition unit and a data analysis module) can monitor the quality of the glass in real time, simplify the production process and improve production efficiency.

[0046] The working principle and usage of a conveying device for a tempered glass production line of this embodiment:

[0047] The present embodiment provides a conveying device for a tempered glass production line, which provides a stable support base for the entire conveying system through a conveying frame 1, adopts a hollow cylinder with an air vent 21 as a conveying roller 2, and connects the conveying roller 2 with the air outlet of an air cooling device 3 through a rotary joint. When the cooling air flow generated by a cooling fan 31 passes through the conveying roller 2, it can be evenly blown to the bottom of the glass from the air vent 21 to achieve rapid cooling of the glass. At the same time, an air filter 32 is added to the air cooling device 3 to ensure the cleanliness of the cooling air and reduce the influence of impurities on the quality of the glass. The application of the flow control valve 33 makes The cooling air volume can be adjusted according to actual needs, ensuring that the glass can reach the ideal cooling state in the shortest time.
