Description

Technical Field

[0001] This utility model relates to the field of coated glass production, specifically to a coated glass air knife cooling device. Background Technology

[0002] Coated glass is a type of glass product with one or more layers of a thin film of metal, alloy, or metal oxide coated onto its surface using a special process. This film significantly alters the optical, thermal, and electrical properties of the glass, giving it functional characteristics not found in ordinary glass. Through surface thin-film technology, coated glass upgrades ordinary glass into a high-end material with energy-saving, aesthetic, and functional properties, and is widely used in modern architecture, transportation, and electronics. With technological advancements, its performance continues to improve while costs gradually decrease, making it a key material for green building and smart living. The production stage of coated glass requires cooling treatment to complete the finished product processing.

[0003] The existing technology has the following problems:

[0004] Current technologies for producing coated glass suffer from poor cooling. After coating, the glass surface relies on natural evaporation or inefficient mechanical wiping for drying, making the drying process a bottleneck. This forces subsequent processes (such as cutting and packaging) to wait, reducing the overall throughput of the production line and impacting capacity. Furthermore, the lack of uniform airflow cooling leads to significant temperature differences on the glass surface, and the concentration of thermal stress can cause cracking or deformation. For example, when thick glass is rapidly cooled, the edges and center shrink at different rates, making it prone to stress cracks. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] A preferred embodiment of the coated glass air knife cooling device provided by this utility model is, for example... Figures 1 to 4 As shown: A cooling device for coated glass air knife includes a frame plate 1, a fixed column 2 is provided on one side of the frame plate 1, a motor 3 is provided at one end of the fixed column 2, a rotating shaft 4 is provided at the output end of the motor 3, a worm gear 5 is provided on the outer wall of the rotating shaft 4, a gear 6 is movably connected to the outer wall of the worm gear 5, a driven shaft 7 is provided on the inner wall of the gear 6, and an air roller 8 is provided on the outer wall of the driven shaft 7.

[0025] An upper air knife 9 is installed on one side of the frame plate 1, a lower air knife 10 is installed on one side of the frame plate 1, a fan 12 is installed on the top of the frame plate 1, an air inlet pipe 13 is installed on one side of the fan 12, and a mounting ear 14 is installed on the top of the frame plate 1. This allows the equipment to have a good cooling effect. The upper air knife 9 and the lower air knife 10 use compressed air to form a high-speed airflow through a slit nozzle, which quickly separates and atomizes the water film on the glass surface like a blade, greatly shortening the drying time and increasing the speed of the production line. In response to the problem of poor cooling effect in the production of coated glass in the prior art, this equipment effectively solves the bottleneck of relying on natural evaporation or inefficient mechanical wiping to dry the glass surface after coating, reduces the waiting time of subsequent processes, and increases the throughput and capacity of the entire production line. By providing uniform airflow cooling, this equipment reduces the problem of thermal stress concentration caused by large temperature differences on the glass surface, effectively preventing stress cracks caused by the different shrinkage rates of the edges and the center when thick glass is rapidly cooled, thus improving product quality.

[0026] In this embodiment, the outer wall of the worm gear 5 is provided with a groove, and the worm gear 5 is movably connected to the gear 6 through the groove. The carefully designed groove structure on the outer wall of the worm gear 5 not only enhances the connection stability between the worm gear 5 and the gear 6, but also achieves more efficient power transmission by optimizing the contact area and friction coefficient.

[0027] Meanwhile, this design allows the worm gear 5 to drive the gear 6 more smoothly during rotation, reducing energy loss and mechanical wear, thereby improving the operating efficiency and durability of the entire cooling equipment. The groove structure also facilitates maintenance and replacement, reducing the maintenance cost of the equipment.

[0028] In this embodiment, two air rollers 8 are provided, and the two air rollers 8 are symmetrically arranged about the horizontal center line of the frame plate 1. The arrangement of two air rollers 8 symmetrical about the horizontal center line of the frame plate 1 not only ensures the uniform distribution of airflow inside the equipment, but also enhances the cooling effect through a dual action. Each air roller 8 is equipped with an independent drive system, which can adjust the speed and airflow direction according to actual needs to adapt to the cooling needs of coated glass of different specifications and shapes.

[0029] In addition, the symmetrical design simplifies the installation and commissioning process of the equipment, improves production efficiency and product quality, and this layout also helps to reduce vibration and noise during equipment operation, thereby improving the comfort of the working environment.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of the coated glass air knife cooling device provided by this utility model is as follows: Figures 1 to 4 As shown: A bearing 11 is provided on one side of the frame plate 1. The frame plate 1 is movably connected to the rotating shaft 4 through the bearing 11. The bearing 11 carefully installed on one side of the frame plate 1 provides stable and flexible support for the rotating shaft 4. This design not only reduces the friction and resistance of the rotating shaft 4 during rotation, but also ensures the stability and reliability of long-term operation through the precision machining and high-quality material selection of the bearing 11.

[0032] Meanwhile, the structure of bearing 11 facilitates equipment maintenance and upkeep, reduces the failure rate caused by wear, and extends the service life of the equipment. The design of bearing 11 also takes into account sealing and dustproof performance, effectively preventing impurities from entering the equipment and ensuring continuous and stable cooling effect.

[0033] In this embodiment, four mounting ears 14 are provided, with each pair of mounting ears 14 forming a group. The two groups of mounting ears 14 are symmetrically arranged about the vertical center line of the frame plate 1. The design of the four mounting ears 14, arranged in pairs and symmetrically about the vertical center line of the frame plate 1, provides a stable support foundation for the entire cooling equipment.

[0034] Furthermore, this symmetrical layout not only enhances the structural strength of the equipment, but also reduces vibration and deformation during operation through evenly distributed mounting points. The mounting ears 14 are made of high-strength materials and can withstand various forces and torques generated during equipment operation, ensuring the stability and safety of the equipment.

[0035] At the same time, this design facilitates the installation and disassembly of the equipment, improves production efficiency and flexibility, and the position and number of mounting ears 14 also take into account the convenience of equipment transportation and storage, making the entire cooling equipment more adaptable to the needs of modern industrial production.

[0036] In use, the entire equipment can be installed on the coated glass transmission equipment by using the mounting ears 14 in conjunction with the mounting structure, so that the upper air knife 9 is positioned above the coated glass and the lower air knife 10 is positioned below the coated glass. Then, the motor 3 and the fan 12 are turned on. The fan 12 injects the airflow into the interior of the frame plate 1 through the air inlet pipe 13. The motor 3 drives the rotating shaft 4 to rotate, which in turn drives the worm gear 5 to rotate and drives the gear 6 to rotate. This drives the driven shaft 7 and the two air rollers 8 to rotate synchronously. The airflow entering the interior of the frame plate 1 is agitated by the air rollers 8 and discharged through the upper air knife 9 and the lower air knife 10. The upper air knife 9 and the lower air knife 10 use compressed air to form a high-speed airflow through the slit nozzle, which quickly separates and atomizes the water film on the glass surface like a blade, greatly shortening the drying time and increasing the production line speed.

[0037] In summary, this air knife cooling equipment for coated glass achieves excellent cooling performance. The upper air knife 9 and lower air knife 10 utilize compressed air to form a high-speed airflow through slit nozzles, rapidly separating and atomizing the water film on the glass surface like a blade. This significantly shortens drying time and increases production line speed. Addressing the problem of poor cooling performance in existing coated glass production technologies, this equipment effectively solves the bottleneck of relying on natural evaporation or inefficient mechanical wiping for drying after glass surface coating. It reduces waiting time in subsequent processes, increases the throughput and capacity of the entire production line, and provides uniform airflow cooling, reducing thermal stress concentration caused by large temperature differences on the glass surface. This effectively prevents stress cracks caused by different shrinkage rates between the edges and center of thick glass during rapid cooling, thus improving product quality.
