Description

Technical Field

[0001] This application relates to the field of glass cooling technology, specifically a flexible bellows grille for cooling irregularly shaped hot-bent tempered glass. Background Technology

[0002] Irregularly shaped hot-bent tempered glass has been widely used in curtain walls, vehicle windows, photovoltaic modules, and other fields due to its unique aesthetic appeal and excellent mechanical properties. However, due to its complex curved surface and uneven thickness, traditional rigid air grating structures struggle to achieve uniform airflow distribution during cooling, easily leading to uneven cooling, stress concentration, and even cracking of the glass surface, severely impacting product quality and yield.

[0003] Currently, conventional tempered glass cooling devices mostly employ fixed air grate structures with fixed air outlet arrangements, making it impossible to adaptively adjust to the glass shape. This is particularly problematic when processing irregular curved glass, resulting in poor contact, low cooling efficiency, and large localized temperature differences. Furthermore, traditional equipment typically only has an upper airflow system, lacking bottom-level coordinating cooling capabilities, leading to asymmetrical cooling of the glass and affecting the tempering effect. Additionally, the support system during the cooling process is relatively simple, lacking flexible protective measures, making it susceptible to mechanical damage to the glass during clamping or cooling. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a flexible bellows grille for cooling irregularly shaped hot-bent tempered glass, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a flexible air box grating for cooling irregularly shaped hot-bent tempered glass, comprising a lower grating frame and an upper grating frame. A hanging unit is provided above the upper grating frame. The hanging unit includes a hanging shaft, a drive seat, a first transmission shaft, an intermediate drive component, a second transmission shaft, and an intermediate transmission assembly. The intermediate drive component is sleeved with one end of the second transmission shaft, and the other end of the second transmission shaft is connected to the intermediate transmission assembly. The intermediate transmission assembly is connected to the first transmission shaft. The first transmission shaft is sleeved with a drive seat, and the drive seat is sleeved with a hanging shaft. The hanging shaft is connected to a lifting fixing frame, and an upper support frame is provided on the lifting fixing frame. A lower support frame assembly is provided on the lower grating frame.

[0006] As a preferred technical solution of this application, the main transmission assembly is provided on both sides of the lower frame of the wind grating. The main transmission assembly includes a support frame and a transmission wheel set, and the transmission wheel set is disposed on the support frame.

[0007] As a preferred technical solution of this application, the upper support frame includes a blower assembly and an elastic cloth bag covering the lifting and fixing frame. The blower assembly is disposed on the lifting and fixing frame, and the air outlet of the blower assembly is also located inside the elastic cloth bag.

[0008] As a preferred technical solution of this application, the lower support bracket assembly consists of four lower supports, which are disposed in the gaps of the lower frame of the air grating.

[0009] As a preferred technical solution of this application, the drive seat is symmetrically arranged on the upper surface of the wind grid frame.

[0010] As a preferred technical solution of this application, the lower end of the lifting shaft is provided with a mounting plate, and the mounting plate is connected to the support hanging parts on the lifting fixing frame by fasteners.

[0011] Compared with the prior art, the beneficial effects of this application are as follows: This application solves the problems of uneven cooling and easy damage to the glass surface that exist in traditional rigid air grids when cooling irregularly shaped glass by organically combining a reasonable mechanical structure with a flexible cooling system. It adopts elastic bags arranged symmetrically at the top and bottom, combined with air blowing groups to form a closed or semi-closed cooling space, so that cold air circulates in the bags. The upper and lower air blowing groups work together to ensure that the airflow evenly covers the entire surface of the glass, which significantly improves the cooling efficiency and cooling uniformity. The elastic bags are made of high temperature resistant and wear-resistant materials, which can adapt to changes in the shape of the glass and achieve flexible fitting. It is particularly suitable for irregularly shaped hot-bent glass with complex curved surfaces and uneven thickness, effectively avoiding stress concentration and cracking problems caused by local temperature differences, avoiding surface defects such as scratches and indentations caused by direct contact between traditional rigid air grids and glass, improving the yield rate, and enhancing the appearance quality and safety of glass.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 1 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-3 This application provides a technical solution: a flexible air box grating for cooling irregularly shaped hot-bent tempered glass, including a lower grating frame 1 and an upper grating frame 2, with a hanging unit provided above the upper grating frame 2.

[0018] The upper frame 2 of the air grid is the upper support platform of the entire device, used to install the hanging unit and related drive components. It is made of welded profiles and has sufficient rigidity and strength to withstand the dynamic load of the hanging unit during the lifting process. The hanging unit is the component that realizes the stability and lifting of the cooling unit.

[0019] The suspension unit includes a suspension shaft 3, a drive seat 4, a first transmission shaft 5, an intermediate drive component 6, a second transmission shaft 7, and an intermediate transmission group 8. The intermediate drive component 6 is sleeved at one end of the second transmission shaft 7, and the other end of the second transmission shaft 7 is connected to the intermediate transmission group 8. The intermediate transmission group 8 is connected to the first transmission shaft 5. The first transmission shaft 5 is sleeved on the drive seat 4, and the suspension shaft 3 is sleeved inside the drive seat 4. The suspension shaft 3 is connected to a lifting fixing frame 9.

[0020] The lifting shaft 3 connects the lifting fixing frame 9 and the drive seat 4, and is responsible for transmitting power from the drive system to the supporting structure below. Its vertical arrangement ensures smooth and reliable lifting action. The drive seat 4 is a node in the transmission link, which converts the rotational motion of the first drive shaft 5 into the vertical up-and-down motion of the lifting shaft 3, and transmits power to the lifting shaft 3, thereby adjusting the up-and-down motion of the lifting fixing frame 9. The first drive shaft 5 connects the drive seat 4 and the intermediate transmission group 8, and is responsible for transmitting power downward to the lifting shaft 3. High-precision couplings or gear mechanisms are used for power transmission to ensure transmission efficiency and synchronization. The intermediate drive component 6 provides the original driving force and is the "power source" of the entire hanging unit. It is located in the middle of the upper surface of the wind grating frame 2. Its power is evenly transmitted to the second drive shaft 7. The second drive shaft 7 transmits the power output from the intermediate drive component 6 to the intermediate transmission group 8. The intermediate transmission group 8 is the transfer station for power transmission and coordinates the power connection between the second drive shaft 7 and the first drive shaft 5. It can be a gearbox, sprocket group or multi-stage linkage mechanism, which can be flexibly configured according to actual needs.

[0021] The lifting and fixing frame 9 receives the lower end of the hanging shaft 3, supports the upper support frame structure, and drives the elastic cloth bag 14 to cover the lifting and fixing frame 9. The air blowing group 13 is activated to blow the elastic cloth bag 14 up. The air blowing group 13 and the elastic cloth bag 14 combine to form a closed cooling space. At this time, the elastic cloth bag 14 can cover the glass according to its shape to complete the cooling.

[0022] The lifting and fixing frame 9 is provided with an upper support frame, and the lower frame 1 of the air grid is provided with a lower support frame assembly.

[0023] The lifting and fixing frame 9 is located at the bottom of the hanging unit and is driven by the hanging shaft 3 to move up and down. It is used to install the elastic cloth bag 14 and the air blowing group 13, and serves as a platform for carrying the cooling airflow; thus achieving flexible covering and stable support for the glass.

[0024] Furthermore, main drive assemblies 10 are provided on both sides of the lower frame 1 of the wind grating. The main drive assembly 10 includes a support frame 11 and a drive wheel set 12, with the drive wheel set 12 disposed on the support frame 11.

[0025] The lower frame 1 of the air grille supports the lower support frame assembly, the main drive assembly 10 and other components. The main drive assembly 10 is the component that enables the entire cooling device to move laterally (walk) in the production line.

[0026] The glass is transferred through the support frame 11 and the transmission wheel set 12. The support frame 11 is fixed on both sides of the lower frame 1 of the wind grating and serves as the installation base for the transmission wheel set 12. It adopts a metal frame structure with welding or bolt connection, which has sufficient strength and rigidity. It supports the transmission wheel set 12 and provides guiding and limiting functions to ensure that the transmission wheel set 12 runs smoothly and prevents deviation or jamming.

[0027] Furthermore, the upper support frame includes a blower assembly 13 and an elastic cloth bag 14 covering the lifting and fixing frame 9. The blower assembly 13 is disposed on the lifting and fixing frame 9, and the air outlet of the blower assembly 13 is also located inside the elastic cloth bag 14.

[0028] Furthermore, the lower support frame assembly consists of four lower support seats 15, which are arranged in the gaps of the lower frame 1 of the air grid, and the lower support seats 15 are also provided with air blowing assembly 13 and elastic cloth bag 14.

[0029] The lower support 15 is fixed in the gap area inside the lower frame 1 of the air grille, which facilitates the installation of the elastic cloth bag 14 and the air blowing assembly 13; it works in conjunction with the air blowing assembly 13 on the upper support frame to ensure that the cold air evenly covers the entire surface of the glass and realizes the upper and lower clamping cooling.

[0030] Furthermore, the drive seat 4 is symmetrically arranged on the upper surface of the wind grating frame 2.

[0031] Furthermore, the lower end of the lifting shaft 3 is provided with a mounting plate 16, which is connected to the support hanging member on the lifting fixing frame 9 by fasteners.

[0032] In use: The hot-bent irregularly shaped glass is placed stably on the main drive assembly 10 on the lower frame 1 of the air grating. The four lower supports 15 are located directly below the glass, with the glass facing the elastic cloth bag 14. The intermediate drive component 6 is activated, and the power is transmitted to the intermediate drive group 8 through the second drive shaft 7. The intermediate drive group 8 transmits the power to the first drive shaft 5, which in turn drives the drive seat 4. The drive seat 4 drives the hanging shaft 3 to descend, and finally the lifting fixed frame 9 reaches the set position. At this time, the upper and lower air blowing groups 13 are activated, and the cold air circulates in the closed space formed by the elastic cloth bag 14. The upper and lower air blowing groups 13 work together to achieve uniform cooling of the entire surface of the glass. After cooling is completed, the main drive assembly 10 is activated, and the equipment moves along the track to the next station or returns to the initial position. The cooled glass can then enter the subsequent inspection, flipping, or conveying process.
