Description

Technical Field

[0001] This invention relates to the field of tempered glass production technology, specifically a quenching device with adjustable air grid spacing for tempered glass processing. Background Technology

[0002] In the production process of tempered glass, fully tempered glass requires extremely high cooling rates, necessitating higher air pressure and denser airflow coverage. By reducing the spacing between the air grates, it is possible to ensure that high-pressure airflow impacts the glass surface. Semi-tempered glass cools relatively slowly; if the spacing between the air grates is too dense, the air pressure will be too high, causing the glass to directly become fully tempered.

[0003] When using the same air grating to produce fully tempered or semi-tempered glass, traditional techniques often require manual disassembly and adjustment of the grating spacing, followed by manual replacement of the corresponding conduit pipes, to switch the air supply. This process is cumbersome, time-consuming, and labor-intensive, resulting in a significant reduction in production changeover efficiency.

[0004] Therefore, the present invention provides a quenching device with adjustable air grid spacing for tempered glass processing to solve the above-mentioned problems. Summary of the Invention

[0009] Preferably, a crossbar is inserted inside the guide block, and a cylinder is fixed on the side wall of the baffle, with the output end of the cylinder fixed to the crossbar.

[0011] A magnetic attraction assembly is provided between the second air grating and the second baffle.

[0012] Preferably, both the first and second sealing plates have receiving cavities, and each receiving cavity is equipped with an air supply mechanism. Each air supply mechanism includes a conduit, a push rod, a sleeve, a return spring, an airbag, and a hose. The conduit is fixedly inserted through the center of the side wall of the receiving cavity, the push rod is slidably inserted through the edge of the side wall of the receiving cavity, the sleeve is sleeved on the outer peripheral wall of the conduit and fixed to the push rod, the airbag is sealed and connected to the end of the conduit, a first connection hole is opened on the side wall of the conduit, a second connection hole is opened on the side wall of the sleeve, the first connection hole and the second connection hole are intermittently connected, the hose is connected between the airbag and the second connection hole, and a one-way valve is installed in the conduit located between the first connection hole and the airbag.

[0016] Compared with the prior art, the present invention provides a quenching device with adjustable air grid spacing for tempered glass processing, which has the following beneficial effects:

[0017] 1. This device, through the use of a linkage mechanism, enables the movable air grating to automatically control the opening and closing of corresponding through holes when sliding left and right to switch areas. Specifically, when the movable air grating moves from one area to another, the through holes in the original area automatically close to prevent airflow leakage, and the opening and closing components in the new area then automatically open, achieving precise airflow supply. This solves the problems of inconvenient air grating adjustment, low switching efficiency, and the need for manual disassembly and assembly of pipelines in existing technologies.

[0018] 2. By incorporating a sliding second air vent and a magnetic suction component within the movable air vent, the effective ventilation area of ​​the vents is altered through their offset movement. As the movable air vent moves forward, the magnetic suction component keeps the second air vent stationary, causing the vents to transition from partially open to fully open. This disrupts the support points for glass shards or debris stuck to the vent walls, causing them to fall off automatically. Furthermore, the air supply mechanism within the sealing plate utilizes the stored airflow for powerful purging, further removing any adhering materials. This design achieves automatic and rapid unblocking of the vents without the need for manual disassembly and cleaning, effectively ensuring the cooling effect and lifespan of the air vent.

[0038] Reference Figures 1-13 This invention provides a technical solution for a quenching device with adjustable air grid spacing for tempered glass processing:

[0039] A tempered glass processing quenching device with adjustable air grate spacing includes a fixing component, an air grate assembly, and a linkage mechanism. The fixing component includes a first baffle 11 and a second baffle 12 arranged opposite to each other; the second baffle 12 has a cavity 15 on its side facing away from the first baffle 11, and the cavity wall of the cavity 15 has fixed air holes and at least two replaceable air holes 31 sequentially formed. The air grate assembly includes a fixed air grate 13 and a movable air grate 21. The fixed air grate 13 is fixed between the first baffle 11 and the second baffle 12 and communicates with the fixed air holes. The movable air grate 21 is movably disposed between the first baffle 11 and the second baffle 12 and can communicate with different replaceable air holes 31. The linkage mechanism includes a drive component and at least two closing components. The drive assembly is connected to the movable air grille 21, driving the movable air grille 21 to move closer to or away from the fixed air grille 13 and to communicate with different replaceable air holes 31; two sealing assemblies are connected to the cavity wall of the cavity, which can seal the replaceable air holes 31 that are not connected to the movable air grille 21.

[0040] Based on the above scheme, for example, please refer to [link / reference]. Figure 2 When the movable air grille 21 is connected to the replaceable air hole 31 on the right, the sealing component on the right opens the corresponding replaceable air hole 31, and the sealing component on the left blocks the corresponding replaceable air hole 31. When the drive component drives the movable air grille 21 to move to the left, the sealing component on the right blocks the corresponding replaceable air hole 31. When the drive component drives the movable air grille 21 to the position of the replaceable air hole 31 on the left, the sealing component on the left opens the corresponding replaceable air hole 31, so that the airflow in the cavity 15 only enters the moved movable air grille 21 and the fixed air grille 13.

[0041] Similarly, when the movable air grille 21 is connected to the left replaceable air hole 31, the left sealing component opens the corresponding replaceable air hole 31, and the right sealing component blocks the corresponding replaceable air hole 31. When the drive component drives the movable air grille 21 to move to the right, the left sealing component blocks the corresponding replaceable air hole 31. When the drive component drives the movable air grille 21 to the position of the right replaceable air hole 31, the right sealing component opens the corresponding replaceable air hole 31, so that the airflow in the cavity 15 only enters the moved movable air grille 21 and the fixed air grille 13.

[0042] As can be seen, through the coordinated use of the drive components and linkage mechanism, the movable air grating 21 can automatically control the opening and closing of the corresponding air pressure zone when sliding left and right under the action of the drive components. That is, when the movable air grating 21 moves from one area to another, the replaceable air holes 31 in the original area will automatically close first to prevent air leakage, and the replaceable air holes 31 in the new area will then automatically open to achieve precise air supply. This allows for flexible adjustment of the position of the movable air grating 21 to meet the quenching requirements of fully tempered and semi-tempered glass, without the need for manual disassembly and replacement of the conductive pipes, effectively solving the problems of inconvenient air grating adjustment and low switching efficiency in the prior art.

[0043] In some optional embodiments, a clearance cavity is provided inside the baffle 11, and a guide hole 111 is provided on the side wall of the clearance cavity. A guide block 212 is fixed to the end of the movable air grille 21, and the guide block 212 slides in the guide hole 111. The drive assembly is located in the clearance cavity and includes a second rack 14, two rotating shafts 18, two third gears 25, two cams 20, and a guide post 17. A dovetail groove is provided on the bottom wall of the clearance cavity, and a dovetail block is slidably provided in the dovetail groove. The second rack 14 is fixed on the dovetail block. Two rotating shafts 18 are distributed along the length of the baffle 11 and are rotatably engaged with the inner wall of the clearance cavity. Two third gears 25 are fixed on the two rotating shafts 18 one-to-one. Both third gears 25 mesh with the second rack 14. Two cams 20 are fixed on the two rotating shafts 18 one-to-one. The guide post 17 is fixed at the end of the guide block 212. The guide post 17 and the two cams 20 alternately abut against each other. A servo motor 19 is installed on the side wall of the baffle 11. The output end of the servo motor 19 is fixed to the rotating shaft 18 located on the side away from the fixed air grille 13.

[0044] Based on the above solution, please refer to Figure 3 and Figure 4 When the servo motor 19 drives the left rotating shaft 18 to rotate clockwise, the left third gear 25 will mesh with the second rack 14 for transmission. The second rack 14 will drive the left cam 20 to rotate clockwise. During the rotation of the left cam 20, the distal end of the cam 20 will press the guide post 17 directly above it to move to the right along the guide hole 111. When the left cam 20 and the guide post 17 complete the pressing action, the guide post 17 will just move to the top of the right rotating shaft 18.

[0045] When the servo motor 19 drives the left rotating shaft to rotate counterclockwise, the left third gear 25 will mesh with the second rack 14 for transmission. The second rack 14 will drive the right third gear 25 to rotate counterclockwise. The right third gear 25 will drive the cam 20 to rotate counterclockwise. During the rotation of the right cam 20, the distal end of the cam 20 will press the guide post 17 directly above it to move to the left along the guide hole 111. When the right cam 20 and the guide post 17 complete the pressing action, the guide post 17 will just move to the top of the left rotating shaft 18.

[0046] It can be seen that by changing the servo motor 19, the moving air grating 21 can be indirectly driven to move in a directional and fixed distance.

[0047] The servo motor 19 is equipped with an external mounting shell and is controlled by an external control terminal.

[0048] There is a certain friction between the guide block 212 and the guide hole 111, which ensures that the guide block 212 has inertia when it stops being subjected to force, thereby ensuring that the moving distance of the moving air grille 21 is completely controlled indirectly by the servo motor 19.

[0049] As described above, the guide block 212 contains a counterweight, so that the center of gravity of the moving air grille 21 and the guide block 212 as a whole is close to the front side. Therefore, when the guide block 212 moves, it can ensure that the moving air grille 21 moves synchronously. Furthermore, a rectangular groove is provided on the front side wall of the baffle 22 to limit the movement of the moving air grille 21, further ensuring that the moving air grille 21 and the guide block 212 move synchronously.

[0050] In one optional embodiment, the sealing assembly is configured as a first sealing assembly and a second sealing assembly. The first sealing assembly includes a first rotating shaft 41, a first sealing plate 42, and a first gear 43. The first rotating shaft 41 rotatably passes through the cavity 15, the first sealing plate 42 is fixed to the first rotating shaft 41, and the first gear 43 is fixed to the first rotating shaft 41. The second sealing assembly includes a second rotating shaft 51, a second sealing plate 52, and a second gear 53; the second rotating shaft 51 rotatably passes through the cavity 15, the second sealing plate 52 is fixed to the second rotating shaft 51, and the second gear 53 is fixed to the first rotating shaft 41. A connecting rod 61 is fixed to the movable air grille 21, and a first rack 62 is fixed to the connecting rod 61. The first rack 62 alternately meshes with the first gear 43 and the second gear 53.

[0051] Based on the above solution, please refer to Figure 2 and Figure 5 When the movable air grille 21 is in the position of the right replaceable air hole 31, as the external force drives the movable air grille 21 to move forward, the movable air grille 21 will drive the first rack 62 to mesh with the second gear 53, the second gear 53 will drive the second rotating shaft 51 to rotate 180° clockwise, and the second sealing plate 52 will block the corresponding replaceable air hole 31; conversely, as the external force drives the movable air grille 21 to move backward, the movable air grille 21 will drive the first rack 62 to mesh with the second gear 53 in the opposite direction, the second gear 53 will drive the first rotating shaft 42 to rotate 180° counterclockwise, and the second sealing plate 52 will open the corresponding replaceable air hole 31.

[0052] Similarly, when the movable air grille 21 is in the position of the left replaceable air hole 31, as the external force drives the movable air grille 21 to move forward, the movable air grille 21 will drive the first rack 62 to mesh with the first gear 43, the first gear 43 will drive the first rotating shaft 41 to rotate 180° clockwise, and the first sealing plate 42 will block the corresponding replaceable air hole 31; conversely, as the external force drives the movable air grille 21 to move backward, the movable air grille 21 will drive the first rack 62 to mesh with the first gear 43 in the opposite direction, the first gear 43 will drive the first rotating shaft 42 to rotate 180° counterclockwise, and the first sealing plate 42 will open the corresponding replaceable air hole 31.

[0053] In some alternative embodiments, a crossbar 213 is inserted inside the guide block 212, and a cylinder 214 is fixed on the side wall of the baffle 11, with the output end of the cylinder 214 fixed to the crossbar 213.

[0054] Cylinder 214 is controlled by an external control terminal.

[0055] Based on the above solution, please refer to Figure 3 and Figure 6 When the output end of the cylinder 214 is extended by the external control terminal, the crossbar 213 will drive the guide block 212 to move forward, and the guide block 212 will drive the movable air grille 21 to move forward synchronously. When the output end of the cylinder 214 is retracted by the external control terminal, the crossbar 213 will drive the guide block 212 to move backward, and the guide block 212 will drive the movable air grille 21 to move backward synchronously.

[0056] It can be seen that the cylinder 214 can drive the movable air grille 21 to move in the front-to-back direction, and at the same time drive the drive assembly to move in the front-to-back direction.

[0057] The crossbar 213 always moves in the front-to-back direction, and the movable air grille 21 can drive the guide block 212 to move in the left-to-right direction on the crossbar 213. Therefore, the crossbar 213 will ensure that the movable air grille 21 moves in the same direction in the left and right directions, thus ensuring stable movement.

[0058] In some optional embodiments, a second air grille 22 is slidably disposed within the movable air grille 21. The bottom of the movable air grille 21 is provided with a plurality of air holes 211, and the bottom of the second air grille 22 is provided with a plurality of air holes 221. The plurality of air holes 211 and the plurality of air holes 221 are connected in a one-to-one correspondence. A magnetic attraction assembly is provided between the second air grille 22 and the baffle 2 12.

[0059] The magnetic attraction component includes a magnetic block one and a magnetic block two. Magnetic block one is located on the second air grating 22, and magnetic block two is located inside the front side wall of the baffle 2 12. Magnetic block one and magnetic block two are close to each other on one side and are opposite magnetic poles.

[0060] Based on the above solution, please refer to Figures 7 to 9 When the movable air grating 21 moves forward, the first magnetic block on the second air grating 22 is attracted by the second magnetic block. Therefore, the second air grating 22 does not move forward with the movable air grating 21. As a result, the movable air grating 21 and the second air grating 22 will be misaligned in the front-back direction. Several air holes 1 211 and several air holes 221 will change from a partially conductive state to a fully conductive state.

[0061] As can be seen, when the movable air grille 21 moves forward, the effective ventilation area formed by air hole 1 211 and air hole 221 will increase, thereby eliminating the support points for glass shards and debris stuck on the inner wall of the original ventilation hole. The glass shards and debris will automatically detach from the inner wall of the air hole. Therefore, the air hole can be quickly cleared without the need for manual disassembly and cleaning of the air grille, thus improving the cooling effect of the air grille.

[0062] In a preferred embodiment, both the first sealing plate 42 and the second sealing plate 52 have a receiving cavity 71. Each receiving cavity 71 is equipped with an air supply mechanism. Each air supply mechanism includes a conduit 72, a push rod 73, a sleeve 74, a return spring 75, an airbag 76, and a hose 77. The conduit 72 is fixedly inserted through the center of the side wall of the receiving cavity 71. The push rod 73 slides through the edge of the side wall of the receiving cavity 71. The sleeve 74 is sleeved on the outer peripheral wall of the conduit 72 and fixed to the push rod 73. The airbag 76 is sealed to the end of the conduit 72. A first connection hole 721 is opened on the side wall of the conduit 72, and a second connection hole 741 is opened on the side wall of the sleeve 74. The first connection hole 721 and the second connection hole 741 are intermittently connected. The hose 77 connects the airbag 76 and the second connection hole 741. A one-way valve is installed inside the conduit 72 located between the first connection hole 721 and the airbag 76.

[0063] Based on the above solution, please refer to Figure 2 , Figure 10 and Figure 11 Taking the first sealing plate 42 as an example, when the movable air grille 21 is connected to the corresponding replaceable air hole 31, the externally supplied airflow will enter the airbag 76 through the duct 72, forcing the airbag 76 to inflate. When the externally supplied airflow is removed, because a one-way valve is installed in the duct 72, the gas will be temporarily stored in the airbag 76. When the movable air grille 21 moves forward, the movable air grille 21 will drive the first gear 43 to rotate through the first rack 62, thereby automatically sealing the replaceable air hole 31. During the process of sealing the replaceable air hole 31, the push rod 73 will contact and squeeze against the front wall of the cavity 15. When the push rod 73 reaches the contraction limit position, that is, when the first sealing plate 42 completely blocks the replaceable air hole 31, the connecting hole 741 and connecting hole 721 on the sleeve 74 are connected. The temporary gas in the airbag 76 will be completely discharged into the second air grid 22 through the hose 77 and the conduit 72, thereby completely removing the glass shards or debris adhering to the inner wall of the air hole, and achieving further rapid unblocking of the air hole.

[0064] When the movable air grille 21 and another replaceable air vent 31 are connected, the process is the same as described above, and will not be repeated here.

[0065] In some optional embodiments, four partition plates 16 are fixed on the inner wall of the cavity 15. The five partition plates 16 divide the cavity 15 into five cooling zones and one spare zone. All five cooling zones are connected to an external fan via air ducts 8. The movable air grilles 21 and the linkage mechanism are each configured with 6N units, where N is a natural number greater than 1.

[0066] It's important to explain that, firstly, during the actual processing of tempered glass, the heated glass needs to be rapidly cooled to allow its surface to solidify and shrink quickly. After this rapid cooling, significant temperature differences and stress remain inside the glass. Gradual cooling with progressively decreasing air pressure allows the glass to cool down evenly and slowly, eliminating residual internal thermal stress and preventing spontaneous breakage or deformation during subsequent storage or use. Therefore, four cooling zones are set up to meet production requirements. (Please refer to [link / reference]). Figure 12 The five cooling zones are, from left to right, high pressure zone, sub-high pressure zone, medium pressure zone, sub-medium pressure zone and low pressure zone. The power of the external fan connected to each cooling zone decreases from left to right.

[0067] In addition, setting up 6N movable air grates 21 not only ensures that the density of the air pressure meets the requirements, but also ensures that each of the five cooling zones can have a cooling effect on the glass after the spacing of the movable air grates 21 is adjusted.

[0068] Based on this, please refer to Figure 3 , Figure 4 and Figure 6 The number of drive components needs to be set to 6N. When the second rack 14 moves to the left, the third gear 25 from right to left will disengage from the second rack 14 in sequence. That is, the third gear 25 from right to left will stop rotating one by one. Thus, each moving air grille 21 will stop moving after completing the equal spacing adjustment. Finally, the amount of shortening of the spacing between two adjacent moving air grilles 21 is uniform, ensuring consistent cooling effect.

[0069] Conversely, when the second rack 14 moves to the right, the third gear 25 from left to right will mesh with the second rack 14 one by one. That is, the third gear 25 from left to right will rotate continuously one by one. Thus, after each movable air grille 21 completes the equal spacing adjustment, it will continue to move to the left, and finally achieve a uniform increase in the spacing between two adjacent movable air grilles 21, thereby ensuring consistent cooling effect.

[0070] In addition, the high-pressure area is connected to the external fan 1 through duct 1, the second-high pressure area is connected to the external fan 2 through duct 2, the medium pressure area is connected to the external fan 3 through duct 3, the medium-low pressure area is connected to the external fan 4 through duct 4, and the low pressure area is connected to the external fan 5 through duct 5.

[0071] In some alternative embodiments, two vertically symmetrically arranged fixed components, movable air vents 21, and linkage mechanisms are provided. The vertically symmetrically arranged movable air vents 21 can cool both sides of the glass.

[0072] In some optional embodiments, the mobile quenching air grid device for tempered glass production also includes a support frame 3. Each fixed component is connected to the support frame 3 by a hydraulic rod. A conveying component is provided between the two mobile air grids 21. The conveying component includes two connecting frames 91, multiple conveying rollers 92, a belt drive mechanism, and a drive box 93. The two connecting frames 91 are fixed side by side on the support frame 3 in the front-to-back direction. The multiple conveying rollers 92 are evenly distributed in the left-to-right direction. The two ends of the multiple conveying rollers 92 rotate one-to-one within the two connecting frames 91. The belt drive mechanism is connected to one end of the multiple conveying rollers 92. The drive box 93 is equipped with a drive component for driving the belt drive mechanism to rotate.

[0073] For different glass thicknesses, the distance between the movable air grille 21 and the glass surface can be adjusted by adjusting the output of the hydraulic rod, thus increasing the applicability.

[0074] Please see Figure 13 When the drive unit starts, it can drive the belt drive mechanism to operate. The belt drive mechanism will drive multiple conveyor rollers 92 to rotate, and then the multiple conveyor rollers 92 will drive the glass to move from right to left.

[0075] The belt drive mechanism is an existing transmission component, and its principle and structure will not be described in detail here.

[0076] Specifically, the operating principle of this invention is as follows:

[0077] When processing from semi-tempered glass to fully tempered glass: First, the output end of cylinder 214 is extended by controlling the external control terminal, so that the moving air grille 21 indirectly drives the second sealing plate 52 to block the corresponding replaceable air hole 31. Then, the servo motor 19 is driven clockwise by controlling the external control terminal, so that the moving air grille 21 moves closer to the fixed air grille 13. Then, the output end of cylinder 214 is retracted by controlling the external control terminal, so that the moved air grille 21 indirectly drives the first sealing plate 42 to open the corresponding replaceable air hole 31, thus completing the position adjustment of the moving air grille 21.

[0078] When processing from semi-tempered glass to fully tempered glass: First, the output end of cylinder 214 is extended by controlling the external control terminal, so that the moving air grille 21 indirectly drives the first sealing plate 42 to block the corresponding replaceable air hole 31. Then, the servo motor 19 is driven counterclockwise by controlling the external control terminal, so that the moving air grille 21 moves away from the fixed air grille 13. Then, the output end of cylinder 214 is retracted by controlling the external control terminal, so that the moved air grille 21 indirectly drives the second sealing plate 52 to open the corresponding replaceable air hole 31, thus completing the position adjustment of the moving air grille 21.

[0079] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
