Description

Technical Field

[0001] This application relates to the field of glass production technology, and more specifically, to a transition roller table for glass production. Background Technology

[0002] In the industrial production process of various glass products such as flat glass, photovoltaic glass, and electronic glass, after the molten glass is formed into a glass ribbon with a fixed thickness and shape through forming equipment (such as float forming tin baths, calendering machines, overflow drawing forming devices, etc.), a transition roller table is needed to ensure a smooth transition from the forming stage to the annealing stage. As a key transitional device connecting the forming equipment and the annealing furnace in the glass production line, the core function of the transition roller table is to receive the newly formed high-temperature glass ribbon and, through the rotation of the rollers, to uniformly and stably transport the glass ribbon into the annealing furnace for subsequent temperature gradient control and stress relief treatment.

[0003] Patent CN220951567U discloses a transition roller table for glass production. This patent features a cleaning mechanism installed inside the roller table, corresponding to each transition roller. By adjusting the distance between the lifting groove at the top of the adjusting rod and the bottom surface of the transition roller using an adjusting handle, the scraper in the lifting groove abuts against the transition roller. During rotation, the transition roller automatically scrapes away impurities, preventing scratches on the bottom surface of the glass strip and improving the protective performance of the transition roller table for the glass strip during use.

[0004] Although the patent enables the transition roller to automatically scrape off impurities during rotation, there is a lack of effective blocking and collection measures for the impurities during their fall. When the impurities are light powders or debris, they are very easy to be blown away by the airflow in the workshop, which not only pollutes the production environment but may also be inhaled by workers and harm their health. Utility Model Content

[0005] To address the aforementioned problems, this application provides a transition roller table for glass production.

[0006] This application provides a transition roller table for glass production, which adopts the following technical solution:

[0007] A transition roller table for glass production includes a fixed frame, a storage shell at the bottom of the fixed frame, and a dust collection assembly inside the storage shell.

[0008] The dust collection assembly is located inside the storage shell and includes a dust collection funnel, a flow channel and a connecting shell connected in sequence. One end of the connecting shell is equipped with a negative pressure dust removal assembly.

[0009] The negative pressure dust removal assembly includes a negative pressure pipeline connected to the connecting shell, and a pump body located on one side of the fixed frame and connected to the negative pressure pipeline.

[0010] Through the above technical solution, the continuous contact between the dust scraper and the transition roller can promptly remove impurities that have adhered and solidified on the surface of the transition roller due to temperature drop, effectively preventing impurities from accumulating and scratching the bottom surface of the glass belt, thus ensuring the quality of the glass belt. At the same time, by setting up the negative pressure dust removal component, the scraped impurities can be collected in a directional manner and quickly transported to an external collection system through negative pressure, solving the problems of impurity accumulation and blockage and flying during the falling process, and reducing pollution to the production environment.

[0011] Furthermore, the pump body's output end is connected to a dust discharge pipe, and a solenoid valve is installed on the dust discharge pipe.

[0012] Furthermore, the storage casing has two connecting rods fixedly connected inside, and multiple fixing plates are fixedly connected to the top of each connecting rod.

[0013] Furthermore, each mounting plate is detachably equipped with a dust scraper, which is connected to the mounting plate via a plug-in assembly.

[0014] Furthermore, the plug-in assembly includes a plug rod located at the bottom of the dust scraper and a corresponding plug hole opened on the fixing plate.

[0015] With the above technical solution, if the dust scraper becomes worn, aged, or has too much dirt on its surface that is difficult to clean due to long-term use, the staff can easily remove it from the fixing plate. They can simply apply an upward force to pull the rod out of the socket for replacement, which is convenient for maintenance.

[0016] Furthermore, multiple parallel transition rollers are rotatably mounted on the fixed frame via bearing assemblies, which are fixed to the fixed frame by bolts.

[0017] Furthermore, the working surface of the dust scraper remains in contact with the roller surface of the transition roller.

[0018] Furthermore, the width of the transition roller is greater than the width of the glass belt.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] (1) This utility model can scrape off impurities that have adhered and solidified on the surface of the transition roller due to the temperature drop in a timely manner through the continuous contact between the dust scraper and the transition roller, effectively avoiding the accumulation of impurities that scratch the bottom surface of the glass belt and ensuring the quality of the glass belt; at the same time, through the setting of the negative pressure dust removal component, the scraped impurities can be collected in a directional manner and quickly transported to the external collection system through negative pressure, which solves the problems of impurity accumulation and blockage and flying during the falling process, and reduces the pollution to the production environment;

[0021] (2) If the dust scraper of this utility model is worn, aged or has too much dirt on its surface that is difficult to clean due to long-term use, the staff can easily remove it from the fixing plate. They can simply apply an upward force to pull the rod out of the socket for replacement, which is convenient for maintenance. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figures 1-5 A transition roller table for glass production includes a fixed frame 1, a storage shell 3 at the bottom of the fixed frame 1, and a dust collection assembly inside the storage shell 3.

[0030] The dust collection assembly is located inside the storage shell 3 and includes a dust collection funnel 4, a flow channel 5 and a connecting shell 6 connected in sequence. One end of the connecting shell 6 is equipped with a negative pressure dust removal assembly.

[0031] The negative pressure dust removal assembly includes a negative pressure pipeline 7 connected to the connecting shell 6, and a pump body 8 located on one side of the fixed frame 1 and connected to the negative pressure pipeline 7.

[0032] In the glass production process, when the glass ribbon is transported from the tin bath to the fixed frame 1, some impurities in the tin bath will be removed from the bottom of the glass ribbon. As the ambient temperature drops after leaving the tin bath, these impurities carried out with the glass ribbon will gradually adhere to the surface of multiple parallel transition rollers 2 due to the temperature change. They will gradually solidify during the continuous rotation of the transition rollers 2, forming an impurity layer attached to the roller surface.

[0033] As the glass belt continues to be transported, the transition roller 2 remains in a rotating state. The transition roller 2 gradually accumulates these solidified impurities, which, if not cleaned in time, can easily scratch the bottom surface of the glass belt that subsequently passes through. At this point, the dust collection assembly installed inside the storage shell 3 begins to function: multiple fixing plates 11 are fixedly connected to the top of the two connecting rods 10 inside the storage shell 3. Because the working surface of the dust scraper 12 is always in close contact with the roller surface of the transition roller 2, the dust scraper 12 continuously scrapes the solidified impurities on the roller surface during the rotation of the transition roller 2, removing the attached impurities. The scraped-off impurities fall naturally under gravity and enter the dust collection funnel 4 of the dust collection assembly, and are then directionally transported to the interior of the connecting shell 6 via the guide channel 5.

[0034] At the same time, the pump body 8 installed on one side of the fixed frame 1 starts to operate. Through the negative pressure pipeline 7 connected to the connecting shell 6, a negative pressure environment is formed inside the connecting shell 6. The impurities collected in the connecting shell 6 are quickly sucked in through the negative pressure pipeline 7 and finally discharged to the external collection system (which can be a collection box, which is existing technology and is not shown in the figure) through the dust discharge pipeline 9 (which is connected to the output end of the pump body 8) (the dust discharge pipeline 9 is equipped with a solenoid valve to control the opening and closing of the dust discharge process). This achieves efficient and continuous cleaning and centralized collection of impurities on the surface of the transition roller 2, effectively avoiding the problem of impurities scratching the bottom surface of the glass belt.

[0035] Reference Figures 1-2 The output end of the pump body 8 is connected to a dust discharge pipe 9, and a solenoid valve is installed on the dust discharge pipe 9.

[0036] Reference Figures 3-5 The storage shell 3 has two connecting rods 10 fixedly connected inside. The top of each connecting rod 10 is fixedly connected to multiple fixing plates 11. Each fixing plate 11 is detachably mounted with a dust scraper 12. The dust scraper 12 is connected to the fixing plate 11 through a plug-in assembly. The plug-in assembly includes a plug rod 13 located at the bottom of the dust scraper 12 and a corresponding plug hole 14 opened on the fixing plate 11. Multiple parallel transition rollers 2 are rotatably mounted on the fixing frame 1 through a bearing assembly. The bearing assembly is fixed on the fixing frame 1 by bolts.

[0037] During the transport of the glass strip, these transition rollers 2 rotate accordingly, thus supporting and conveying the glass strip. To ensure the coordinated rotation of the transition rollers 2, meshing gears are installed at the ends of their roller shafts. Through the meshing relationship between the gears, power is sequentially transmitted to the other transition rollers 2, ensuring that all transition rollers 2 rotate in a coordinated manner, thereby stably completing the glass strip transport.

[0038] After a period of use, the dust scraper 12 will wear out or become dirty on its outer wall. At this time, the transition roller 2 needs to be removed. First, loosen the bolts fixing the bearing assembly and the fixing frame 1, remove the bearing assembly from the fixing frame 1, and then completely remove the transition roller 2 from the equipment to fully expose the dust scraper 12 below. After that, apply an upward force to pull the insert rod 13 at the bottom of the dust scraper 12 out of the corresponding insertion hole 14 on the fixing plate 11 to complete the removal of the dust scraper 12.

[0039] After the maintenance is completed or a new dust scraper 12 is prepared, align the insertion rod 13 at its bottom with the insertion hole 14 on the fixing plate 11, apply downward force to insert the insertion rod 13 into the insertion hole 14, and complete the installation of the dust scraper 12; finally, reinstall the transition roller 2 back onto the fixing frame 1 through the bearing assembly, tighten the bolts to fix the bearing assembly, restore the normal structure of the equipment, and ensure that the transition roller 2 and the dust scraper 12 re-form the correct contact fit.

[0040] The dust scraper 12 can often be made of high-strength engineering plastics (such as polytetrafluoroethylene, nylon, etc.) or elastic rubber. The hardness of this material is lower than that of the metal roller surface of the transition roller 2. When it comes into contact with the transition roller 2 and scrapes away impurities, it can effectively clean solidified impurities with its own structural strength, and avoid scratching or wearing the surface of the transition roller 2 through its own elasticity or low hardness.

[0041] Meanwhile, this type of material has good heat resistance and chemical stability, and can adapt to the temperature environment and possible impurities in the glass production process. It maintains its own performance stability during contact friction, thereby ensuring that the transition roller 2 is not damaged while achieving the impurity cleaning function.

[0042] Reference Figures 1-2 The working surface of the dust scraper 12 is in contact with the roller surface of the transition roller 2, and the width of the roller body of the transition roller 2 is greater than the width of the glass belt.

[0043] Working principle: When the glass ribbon is transferred from the tin bath to the fixed frame 1, the impurities in the tin bath carried at the bottom of the glass ribbon are moved out with the glass ribbon. After leaving the tin bath, due to the decrease in ambient temperature, the impurities gradually adhere to the surface of the transition roller 2 of the fixed frame 1, and solidify to form an impurity layer during the rotation of the transition roller 2.

[0044] The rotation of the transition roller 2 is powered by a drive motor, which transmits the power to other transition rollers 2 in sequence through meshing gears at the ends of the roller shafts, ensuring that all transition rollers 2 rotate in a coordinated manner to support and transport the glass belt.

[0045] During the glass belt conveying process, the working surface of the dust scraper 12 remains in contact with the roller surface of the transition roller 2. When the transition roller 2 rotates, the dust scraper 12 continuously scrapes the solidified impurities on the roller surface to remove the impurities.

[0046] The scraped-off impurities fall into the dust collection funnel 4 of the dust collection assembly inside the storage shell 3 under the action of gravity, and are then transported to the connecting shell 6 through the guide channel 5. At the same time, the pump body 8 on one side of the fixing frame 1 starts, and a negative pressure is formed in the connecting shell 6 through the negative pressure pipeline 7, which draws the impurities into the negative pressure pipeline 7. Finally, the impurities are discharged to the external collection system through the dust discharge pipeline 9 connected to the output end of the pump body 8, thus achieving efficient cleaning and centralized collection of impurities.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
