Description

Technical Field

[0001] This invention relates to the field of glass tempering processing, and in particular to a glass tempering equipment, glass processing equipment, and glass tempering process. Background Technology

[0002] Physically tempered glass is an indispensable key material in industries such as construction, home appliances, and automobiles. Its superior safety and high mechanical strength stem from the compressive stress layer on its surface. This compressive stress layer is formed by rapidly and uniformly quenching glass heated to near its softening point within a wind grid.

[0003] Uniformity during the tempering and quenching process is crucial to the quality of tempered glass. Any uneven cooling will directly lead to uneven stress distribution on the glass surface, resulting in optical distortion, commonly known as "wind spots" or "stress spots." This defect is visible to the naked eye under specific lighting conditions, severely affecting the appearance quality of the glass, causing product downgrading or even scrapping, and resulting in huge economic losses.

[0004] Currently, a cold cooling system is commonly used to cool tempered glass. This system typically consists of a high-pressure blower, air ducts, an air box, and two rows of nozzles arranged in a nozzle plate. The cold air blown out by the nozzle plate rapidly cools the glass, achieving the cold cooling process.

[0005] Regarding the aforementioned technologies, since there is an installation gap between the nozzle plate and the air box, during long-term continuous production, due to mechanical vibration of the tempering equipment or unstable ventilation airflow, dust can easily enter the installation gap. Over time, this can cause the nozzle plate to deform, which in turn seriously affects the stability of the airflow emitted from the nozzle plate, making the tempered glass prone to wind spots. Summary of the Invention

[0006] To address the problem of dust accumulation and deformation in the nozzle plate of tempering equipment, this invention provides a glass tempering device, a glass processing device, and a glass tempering process.

[0007] In a first aspect, the present invention provides a glass tempering device, which adopts the following technical solution:

[0013] Preferably, the flow guiding assembly further includes reinforcing rods, and a plurality of reinforcing rods are fixedly installed on two adjacent air guide plates, wherein the cross-section of the reinforcing rods is arc-shaped.

[0014] Preferably, the flow guiding assembly further includes an intermediate guide plate and a fixing plate. Multiple mounting rods are fixedly installed on two adjacent air boxes in the upper air grid mechanism. The fixing plate passes through the mounting rods and is fixedly connected to the mounting rods by nuts. Inclined abutment plates are fixedly installed on the fixing plate. The abutment plates on both sides of the fixing plate abut against the sides of the nozzle plate. The intermediate guide plate is fixedly installed on the mounting rods. The intermediate guide plate and the nozzle plate are arranged alternately.

[0015] Preferably, the air grating mechanism further includes a lifting assembly, which includes guide wheels, guide rails, and telescopic cylinders. Multiple guide wheels are fixedly mounted on the air box, and multiple guide rails are fixedly mounted on the frame of the tempering equipment. The guide wheels roll on the guide rails, and two opposing air boxes move on the frame via the guide wheels and guide rails to adjust the distance between the two opposing air boxes and the tempered glass surface. The cylinder bodies of multiple telescopic cylinders are fixedly mounted on the frame, and the telescopic cylinders are fixedly connected to the non-blowing end of the air box. The telescopic cylinders drive the air box to move on the frame.

[0016] Preferably, the lifting assembly further includes a locking device, which is fixedly installed on the bellows, and the output shaft of the locking device is connected to the rotating shaft of the guide wheel.

[0017] Secondly, the present invention provides a glass processing equipment, which adopts the following technical solution:

[0019] Thirdly, the present invention provides a glass tempering process, which adopts the following technical solution:

[0020] A glass tempering process includes a glass processing apparatus as described in the second aspect, and the following steps:

[0021] Loading: The pre-treated glass sheet is conveyed to the heating furnace;

[0022] Heating: In the heating furnace, the glass is heated to a tempering temperature of 600℃~720℃ and held at that temperature for 90s~500s;

[0023] Cold extraction: The heated glass is rapidly fed into the air grid mechanism, the high-pressure blower is started, and high-pressure airflow is sprayed onto the upper and lower surfaces of the glass through the nozzle plate array on the air box for rapid cooling; wherein, the air pressure of the high-pressure blower is controlled at 8kPa to 20kPa, and the cooling time is 15s to 60s;

[0024] Cooling and unloading: The quenched glass is transported to the unloading table for stacking.

[0025] In summary, the present invention has at least one of the following beneficial technical effects:

[0026] 1. By utilizing the snap-fit ​​method between the first slot and the fixed support leg, multi-angle and multi-edge sealing and multi-segment and multi-plane support are achieved, which improves the sealing strength and installation stability between the nozzle plate and the fixed seat.

[0027] 2. The I-beam structure of the fixed support legs can effectively absorb and suppress high-frequency vibrations generated by high-pressure airflow, prevent the nozzle plate from loosening, and improve the stability of the airflow. The snap-fit ​​connection method may allow for easier disassembly and installation of the nozzle plate assembly when maintenance or replacement is required.

[0028] 3. The reinforcing plate and the first fixing bolt tightly connect the fixed leg, the reinforcing plate and the fixing seat into a stable structure, which greatly enhances the mechanical strength and deformation resistance of the entire fixing point, reduces the possibility of the fixed leg deforming outward, and further improves the sealing effect.

[0029] 4. By adjusting the motor-driven adjusting shaft and the air regulating plate, the opening degree of the dampers in different areas of the air box can be controlled in real time and with precision, thereby adjusting the air volume and airflow angle of the corresponding nozzles.

[0030] 5. The reinforcing rods provide effective support between adjacent air guide plates, significantly increasing the overall rigidity and bending strength of all air guide plates, preventing deformation or swaying under high-pressure airflow, and ensuring the accuracy and long-term reliability of airflow adjustment. The curved cross-section of the reinforcing rods reduces the possibility of the reinforcing rods themselves generating cyclones, making the airflow more stable.

[0031] 6. Driven by a telescopic cylinder, the entire bellows mechanism can be smoothly raised and lowered along the guide rail, allowing for precise and flexible adjustment of the distance between the upper and lower air grilles and the glass. It can adapt to glass of various thicknesses, optimizing cooling efficiency and quality by adjusting the distance. Attached Figure Description

[0048] Example 1:

[0049] This invention discloses a glass tempering device. (Refer to...) Figures 1 to 9 A glass tempering device mainly includes an air grid mechanism 100, which is fixedly installed inside the tempering device. Two sets of air grid mechanisms 100 are arranged opposite the glass tempering surface. The air grid mechanism 100 includes an air box 110, an air inlet pipe 111, a nozzle plate 112, an air guide plate 113, and a fixing component 120. The air box 110 is fixedly connected to the frame 400 of the tempering device. The air inlet pipe 111 is fixedly connected to the air inlet of the air box 110. An air outlet 115 is opened at one end of the air box 110. Multiple nozzle plates 112 are fixedly installed on the air box 110 and are inside the air outlet 115.

[0050] The fixing assembly 120 includes a fixing base 121 and a fixing leg 122. The fixing base 121 is fixedly connected to the air guide plate 113 by welding or integral molding. The fixing base 121 has a first slot 123, and the openings of two adjacent first slots 123 face opposite directions. The top and bottom ends of the fixing leg 122 extend outward in the horizontal direction with extension portions 127. The fixing leg 122 is arranged in an "I" shape. The extension portion 127 at the top end of the fixing leg 122 is fixedly connected to the bottom of the nozzle plate 112 by welding or integral molding. The extension portion 127 at the bottom end of the fixing leg 122 is engaged with the fixing base 121 through the first slot 123. The nozzle plate 112 has multiple air nozzles 114, which are arranged alternately among each other.

[0051] When assembling the air grille mechanism 100, the nozzle plate 112, which is equipped with fixed support legs 122, is inserted and fixed to the fixed base 121 along the installation direction using the snap-fit ​​engagement between the fixed support legs 122 and the first slot 123. A screw can be inserted between the fixed support legs 122 and the fixed base 121 for reinforcement. The snap-fit ​​engagement between the first slot 123 and the fixed support legs 122 achieves multi-angle and multi-edge sealing, as well as multi-segment and multi-plane support, improving the sealing strength and installation stability between the nozzle plate 112 and the fixed base 121. Simultaneously, the I-beam structure of the fixed support legs 122 effectively absorbs and suppresses high-frequency vibrations generated by high-pressure airflow, preventing the nozzle plate 112 from loosening and improving the stability of the outlet airflow. The snap-fit ​​connection method allows for easier disassembly and installation of the nozzle plate 112 assembly when maintenance or replacement is required. The staggered layout of the 114 air jets helps the airflow cover the glass surface more evenly, avoiding cooling dead zones caused by direct airflow and further improving cooling uniformity. The high-strength sealing effect reduces the entry of dust and shortens the time interval for cleaning and maintenance.

[0052] Reference Figures 1 to 4 In some embodiments, the fixing assembly 120 further includes a reinforcing plate 124 and a first fixing bolt 125. The reinforcing plate 124 has a second slot 126, which is used to securely engage with the extension 127 at the bottom of the fixed leg 122. The upper end of the reinforcing plate 124 abuts against the bottom surface of the extension 127 at the top of the fixed leg 122, and the lower end of the reinforcing plate 124 abuts against the fixing seat 121. The reinforcing plate 124 is fixedly connected to the bottom end of the fixing seat 121 by the first fixing bolt 125. The reinforcing plate 124 and the first fixing bolt 125 tightly connect the fixed leg 122, the reinforcing plate 124, and the fixing seat 121 into a stable structure, greatly enhancing the mechanical strength and deformation resistance of the entire fixing point, reducing the possibility of outward deformation of the fixed leg 122, and further improving the sealing effect.

[0053] Reference Figure 4 In some embodiments, the fixing assembly 120 further includes a second fixing bolt 128, through which the extension 127 at the top of the fixing leg 122 is fixedly connected to the top of the reinforcing plate 124. By directly fixing the extension 127 at the top of the fixing leg 122 to the top of the reinforcing plate 124 using the second fixing bolt 128, an additional mechanical fixing connection is provided besides the snap-fit ​​and bottom surface contact, forming a double safety mechanism of "snap-fit ​​+ bolt fastening," thus improving the overall connection safety of the structure.

[0054] Reference Figures 3 to 5 In some embodiments, the air grating mechanism 100 further includes a flow guiding assembly 130. Multiple sets of flow guiding assemblies 130 are sequentially arranged along the air delivery direction of the air box 110. Each flow guiding assembly 130 includes an adjusting shaft 131, an air adjusting plate 132, and an adjusting motor 133. The adjusting shaft 131 is rotatably mounted inside the air box 110. An electromagnetic lock is mounted on the adjusting motor 133. When the adjusting motor 133 needs to drive the adjusting shaft 131 to rotate, the electromagnetic lock is energized, and the locking block on the electromagnetic lock disengages from the output shaft of the adjusting motor 133, allowing the adjusting motor 133 to drive the adjusting shaft 131 to rotate. After adjustment, the electromagnetic lock is de-energized, and the locking block of the electromagnetic lock grips the output shaft of the adjusting motor 133, locking the adjusting shaft 131. The air adjusting plate 132 is fixedly mounted on the adjusting shaft 131, and the adjusting motor 133 is fixedly mounted on the air box 110. The output shaft of the adjusting motor 133 is drively connected to the adjusting shaft 131. By adjusting the motor 133 driving the adjusting shaft 131 and the air regulating plate 132, the opening degree of the dampers in different areas of the air box 110 can be controlled in real time and with precision, thereby adjusting the air volume and airflow angle of the corresponding nozzles. This allows operators to customize the cooling mode for ultra-thin glass, extra-large glass panels, irregularly shaped glass, or glass requiring special stress distribution, effectively reducing processing defects such as deformation and cracking, and greatly expanding the processing range and capabilities of the equipment. The air volume in non-critical areas can be shut off or reduced as needed to achieve energy-saving operation.

[0055] Reference Figures 3 to 5 In some embodiments, the airflow guiding assembly 130 further includes reinforcing rods 134, multiple reinforcing rods 134 being fixedly installed on two adjacent air guide plates 113, with the reinforcing rods 134 having an arc-shaped cross-section. The reinforcing rods 134 form effective support between adjacent air guide plates 113, significantly increasing the overall rigidity and bending strength of all air guide plates 113, preventing deformation or swaying under high-pressure airflow, and ensuring the accuracy and long-term reliability of airflow adjustment. The arc-shaped cross-section of the reinforcing rods 134 reduces the possibility of the reinforcing rods 134 themselves generating cyclones, making the airflow more stable.

[0056] Reference Figures 6 to 8 In some embodiments, the airflow guiding assembly 130 further includes an intermediate guide plate 135 and a fixing plate 136. Multiple mounting rods 138 are fixedly installed on adjacent air boxes 110 in the upper air grid mechanism 100. The fixing plate 136 passes through the mounting rods 138 and is fixedly connected to the mounting rods 138 by nuts. Inclined abutment plates 137 are fixedly installed on the fixing plate 136, with the abutment plates 137 on both sides of the fixing plate 136 abutting against the sides of the nozzle plates 112. The intermediate guide plate 135 is fixedly installed on the mounting rods 138, and the intermediate guide plate 135 and the nozzle plates 112 are arranged alternately. The design of the intermediate guide plate 135 and the fixing plate 136 allows for a smooth transition between the nozzle plates 112 of adjacent air boxes 110, forming a continuous and undisturbed cooling plane. The abutment plate 137 presses against the side of the nozzle plate 112, eliminating installation gaps and preventing abnormal airflow from being ejected or leaking from the gaps. This ensures the ultimate uniformity of airflow throughout the entire glass width direction and reduces the possibility of vibration in the intermediate guide plate 135, thus improving the stability of the airflow.

[0057] Reference Figure 9 and Figure 10 In some embodiments, the air grating mechanism 100 further includes a lifting assembly 140, which includes guide wheels 141, guide rails 142, and telescopic cylinders 143. Multiple guide wheels 141 are fixedly mounted on the air boxes 110, and multiple guide rails 142 are fixedly mounted on the frame 400 of the tempering equipment. The guide wheels 141 roll on the guide rails 142. Two opposing air boxes 110 move on the frame 400 via the guide wheels 141 and guide rails 142 to adjust the distance between the two opposing air boxes 110 and the tempered glass surface. The cylinder bodies of multiple telescopic cylinders 143 are fixedly mounted on the frame 400, and the telescopic cylinders 143 are fixedly connected to the non-blowing end of the air box 110. The telescopic cylinders 143 drive the air box 110 to move on the frame 400. Driven by the telescopic cylinders 143, the entire air box 110 mechanism can be smoothly raised and lowered along the guide rails 142, thereby precisely and flexibly adjusting the distance between the upper and lower air grates and the glass. It can adapt to glass of various thicknesses and optimize cooling efficiency and quality by adjusting the spacing. For example, thin glass requires a closer distance to increase the cooling rate, while thick glass requires a slightly farther distance to prevent the surface from overcooling and the interior from undercooling, which could lead to cracking.

[0058] Reference Figure 9In some embodiments, the lifting assembly 140 further includes a locking device 144, which is fixedly mounted on the air box 110. The output shaft of the locking device 144 is connected to the rotating shaft 145 of the guide wheel 141. The guide wheel 141 can be a gear-shaped guide wheel 141, and the guide rail 142 can be a rack and pinion guide rail 142. By utilizing the meshing of the gear on the guide wheel 141 and the rack on the guide rail 142, the locking device 144 can directly lock the rotating shaft of the guide wheel 141, preventing any movement of the air grating during operation and improving the absolute stability and repeatability of process parameters.

[0059] The implementation principle of a glass tempering device according to an embodiment of the present invention is as follows:

[0060] By utilizing the snap-fit ​​engagement between the first slot 123 and the fixed support leg 122, multi-angle and multi-edge sealing, as well as multi-segment and multi-directional support, are achieved, greatly enhancing the sealing strength and installation stability between the nozzle plate 112 and the fixed seat 121. The I-beam structure of the fixed support leg 122 effectively absorbs and suppresses high-frequency vibrations generated by the high-pressure airflow, preventing the nozzle plate 112 from loosening. While ensuring stable airflow, its snap-fit ​​design also facilitates maintenance and replacement. The added reinforcing plate 124 and the first fixing bolt 125 tightly connect the fixed support leg 122, the reinforcing plate 124, and the fixed seat 121 into a stable whole, significantly improving mechanical strength and resistance to deformation. The sealing effect has been optimized in one step; by adjusting the motor 133 to drive the air regulating plate 132, the opening of the air damper in different areas can be precisely controlled in real time, thereby flexibly adjusting the air volume and airflow angle; the arc-shaped cross-section reinforcing rod 134 set between adjacent air guide plates 113 not only significantly enhances the overall rigidity and bending strength and prevents the air regulating plate 132 from deforming and swaying, but also effectively reduces the possibility of generating its own cyclone, making the airflow more stable; in addition, by driving the air box 110 mechanism to rise and fall smoothly along the guide rail 142 through the telescopic cylinder 143, the distance between the air grid and the glass can be precisely and flexibly adjusted, so that the equipment can adapt to the cooling requirements of glass of different thicknesses, and comprehensively optimize the cooling efficiency and the final product quality.

[0062] This invention discloses a glass processing apparatus. (Refer to...) Figure 10 A glass processing apparatus includes a glass tempering apparatus as described in Example 1, and includes a heating furnace 200 and a conveying roller 300. The conveying roller 300 is rotatably mounted on a frame 400. A high-pressure air compressor is fixedly connected to an air inlet pipe 111. The polished glass is transported to the heating furnace 200 for heating via the conveying roller 300 mounted on the frame 400. The heated glass is then transported to the air grid mechanism 100 for cold extraction via the conveying roller 300.

[0063] The implementation principle of a glass processing equipment according to this invention is as follows:

[0064] This processing equipment can produce higher quality tempered glass with no wind spots, uniform stress, and greater consistency. It can also process a wider range of products, from thin to thick, from ordinary to irregularly shaped glass, and the equipment itself is more durable and energy-efficient.

The air pressure of the high-pressure blower is controlled at 8 kPa to 20 kPa, and the cooling time is 15 s to 60 s.

[0070] S4: Cooling and Unloading: The quenched glass is transported to the unloading table for stacking.
