Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and specifically provides an efficient glass tempering device. Background Art

[0002] Tempered glass belongs to safety glass. Tempered glass is a kind of prestressed glass. To improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass bears external force, the surface stress is offset first, thereby improving the bearing capacity and enhancing the wind resistance, cold and heat resistance, impact resistance, etc. of the glass itself. The production of tempered glass is to first cut ordinary annealed glass into required sizes, then heat it to about 700 degrees close to the softening point, and then perform rapid and uniform cooling. After tempering, uniform compressive stress is formed on the glass surface, while tensile stress is formed inside, so that the bending and impact resistance of the glass are improved. Its strength is about more than four times that of ordinary annealed glass. The heated ordinary glass needs to be cooled evenly during the cooling process to ensure that the internal stress of the tempered glass after heating can be dissipated just right.

[0003] A glass tempering device with the publication number of "CN113860713A" belongs to the technical field of tempered glass. A tempering box and a cooling box are sequentially installed from right to left above the connecting frame. An anti-slip conveying roller is rotatably connected in the connecting frame. Connecting rods are movably embedded around the anti-slip conveying roller. An adsorption disc is nested on the top of the anti-slip conveying roller. A transmission gear is fixedly connected to the left end of the anti-slip conveying roller. A thin glue layer is fixedly connected to the bottom of the adsorption disc. This kind of glass tempering device can ensure the uniform cooling of the glass, greatly reducing the problem that the heated glass is prone to burst due to uneven cooling speed during the cooling process.

[0004] However, the prior art and the above application still have the following defects: 1. Before tempering treatment, during the conveying process, the dust on the lower surface of the glass is not easy to remove compared with the dust on its upper surface, and the dust will have an adverse effect on the quality of tempered glass. Therefore, there is a lack of an effective bottom surface dust removal structure in the prior art. 2. During the cooling process after the glass tempering treatment, the distance between the air outlet of the cold air device and the glass cannot be controlled, resulting in local stress concentration during cooling and posing a potential hazard of glass bursting.

Detailed implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Example 1, please refer to Figures 1 to 9 , the present invention discloses an efficient glass toughening treatment device, including a toughening furnace 11 and a conveying table 1 arranged on one side of the toughening furnace 11. A conveying component is arranged on the conveying table 1 for conveying the glass to be processed into the toughening furnace 11. The conveying component includes a conveying roller 2, the conveying roller 2 is rotatably installed on the conveying table 1, one end of the conveying roller 2 is provided with a first motor 3, and the surface of the conveying roller 2 is provided with bushing 5 arranged in an equidistant array.

[0029] In this embodiment, a conveying roller 2 is arranged on the conveying table 1. The glass to be toughened is placed on the conveying roller 2, and the first motor 3 is started to drive the conveying roller 2 to rotate, so as to convey the glass and convey the glass into the toughening furnace 11 for toughening treatment.

[0030] It should be noted that only one group of conveying rollers 2 is shown in the drawings. In the actual production process, the length of the conveying table 1 is set according to production needs, and is not limited to one group of conveying rollers 2.

[0031] Lifting components are arranged on both sides of the conveying roller 2. The lifting components include floating rollers 4 arranged in an equidistant array on both sides of the conveying roller 2, and the surface of the floating rollers 4 is also provided with bushing 5 arranged in an equidistant array.

[0032] In order to achieve stable transportation of the glass, floating rollers 4 are arranged in an equidistant array on both sides of the conveying roller 2. Bushings 5 are provided on the surfaces of the conveying roller 2 and the floating rollers 4. Among them, the bushing 5 is fixedly connected to the conveying roller 2, and the bushing 5 is rotatably connected to the floating roller 4. The use of the bushing 5 can not only reduce the contact area between the conveying assembly and the glass, but also minimize the friction generated by the conveying assembly on the glass, thus ensuring the quality of the glass after tempering treatment.

[0033] Embodiment 2. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 9 , a cleaning assembly for dust removal of the bottom surface of the glass is further provided on the conveying table 1. The cleaning assembly includes a first rotating shaft 12 for friction dust removal of the bottom surface of the glass and an electrostatic dust removal rod 17 for dust removal of the first rotating shaft 12. Brush hairs 15 are provided on the surface of the first rotating shaft 12. Axle seats 14 are fixed at both ends of the first rotating shaft 12. A first spring 13 is connected between the bottom of the axle seat 14 and the upper surface of the conveying table 1. A guide rod is penetrated through the first spring 13, and the guide rod is slidably connected to the conveying table 1. The first rotating shaft 12 is rotatably installed on one side of the floating roller 4.

[0034] In this embodiment, a first rotating shaft 12 is provided on the conveying table 1. Brush hairs 15 are provided on the surface of the first rotating shaft 12, and the first rotating shaft 12 and the brush hairs 15 are elastically connected to the conveying table 1 by means of the first spring 13 and the guide rod. When the glass is placed on the surface of the bushing 5 of the conveying roller 2 and the floating rollers 4, due to the elastic tension of the first spring 13, the brush hairs 15 are closely attached to the lower surface of the glass. When the glass moves, it rubs against the brush hairs 15, and the dust attached to the bottom surface of the glass is swept clean.

[0035] A through groove 22 is opened in the conveying table 1 below the first rotating shaft 12. The cleaning assembly further includes an air duct 16. Air nozzles 19 communicating with the air duct 16 are arranged in an equidistant array on the top of the air duct 16. The air outlet of the air nozzle 19 is located directly below the through groove 22.

[0036] In this embodiment, a through groove 22 is provided below the first rotating shaft 12 to facilitate the discharge of the swept dust, minimizing the dust falling on the conveying table 1. At the same time, an air duct 16 is provided below the through groove 22. One end of the air duct 16 is connected to an air suction fan. During dust removal, the air suction fan is turned on to further adsorb the removed dust, avoiding dust flying or dust accumulation on the upper surface of the conveying table 1, which is not conducive to the dust removal treatment of the bottom surface of the glass during subsequent glass transportation.

[0037] Embodiment 3. This embodiment is an explanatory description based on Embodiment 1. Specifically, please refer to Figures 1 to 9A lifting rod 6 is arranged between two adjacent groups of shaft sleeves 5, and a rotatable lifting wheel 7 is arranged at one end of the lifting rod 6. A pulley 23 is fixed to one end of the floating roller 4, and the pulleys 23 are connected by a second conveyor belt 10. One end of one group of floating rollers 4 is driven by a second motor 8 through a first conveyor belt 9. The lifting rod 6 is arranged as a telescopic structure, and the telescopic structure is used to adjust the length of the lifting rod 6.

[0038] In this embodiment, a lifting rod 6 is provided between two adjacent sets of sleeves 5 on the surface of the floating roller 4. After the glass is tempered, it returns to the conveying assembly, and the second motor 8 is started to drive the first conveyor belt 9 to transmit to the pulley 23. The pulley 23 drives the floating roller 4 to rotate 90°, so that the lifting rod 6 flips 90°, thereby driving the glass to be lifted to a certain height. At this time, the air-cooling fan is moved between the glass and the conveying platform 1 to air-cool the tempered glass.

[0039] The length of the lifting rod 6 can be adjusted to control the distance between the glass and the air outlet of the cold air device, so as to better ensure the air cooling effect. One end of the lifting rod 6 is connected to an extension rod 24, one end of the lifting wheel 7 is connected to a hollow plate 35, the extension rod 24 is inserted into the hollow plate 35, and the extension rod 24 is locked in the hollow plate 35 by a locking bolt 36.

[0040] It should be noted that the cold air is provided by an external cold air device. When in use, the cold air machine can be moved between the glass and the conveying platform 1.

[0041] In the air cooling process of tempered glass, the distance between the cold air outlet and the glass needs to be determined comprehensively based on the actual application scenario and the thickness of the glass. The general recommendation is: 5-10mm. This range can balance the cooling uniformity and process efficiency. There are also the following special scenarios: For large-sized or thick glass (such as 10mm), it can be appropriately expanded to 8-15mm to avoid local stress concentration. In daily production, the cold air spacing is also related to the glass thickness. When the glass thickness is ≤12mm, the spacing should be 1.5 times the thickness (such as 9mm spacing is recommended for 6mm glass); when the glass thickness is >12mm, the spacing needs to be greater than 2 times the thickness (such as 30mm spacing is recommended for 15mm glass).

[0042] The air duct 16 is rotatably installed on the bottom surface of the conveying platform 1. The cleaning component also includes an electrostatic dust removal rod 17 for dust removal on the first rotating shaft 12. The electrostatic dust removal rod 17 is arranged below the through groove 22, and a dust collecting box 18 is provided on the outside of the electrostatic dust removal rod 17. The air duct 16 is fixedly connected to one side of the dust collecting box 18.

[0043] In this embodiment, an electrostatic dust removal rod 17 is provided below the through slot 22, which can absorb the dust that is not sucked away by the suction fan, and prevent the dust after cleaning from scattering and flying as much as possible, thereby affecting the dust removal effect on the glass.

[0044] Example 4: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 , a driving assembly is provided at one end of the floating roller 4, and the air duct 16 is driven to flip through the driving assembly. The driving assembly includes a gear 25 fixedly installed at one end of the floating roller 4, a fixing frame 30 is fixed at one side of the conveying platform 1, a rack 26 is slidably installed in the fixing frame 30, and the rack 26 and the gear 25 are meshed. The driving assembly includes a connecting shaft 27 connected to the bottom of the rack 26, and a pressing plate 28 is connected to the bottom end of the connecting shaft 27. The second rotating shaft 20 is fixedly connected to both ends of the air duct 16, and the second rotating shaft 20 is rotatably connected to the bottom surface of the conveying platform 1. An extension plate 21 is provided at one end of the second rotating shaft 20, and the pressing plate 28 and the extension plate 21 are matched.

[0045] In this embodiment, a gear 25 is provided at one end of the floating roller 4. During the rotation of the floating roller 4, the floating roller 4 drives the gear 25 to rotate, thereby driving the rack 26 on one side to move downward in the vertical direction, and in turn driving the connecting shaft 27 and the pressure plate 28 to move downward synchronously. Since an extension plate 21 is provided at one end of the second rotating shaft 20, the pressure plate 28 presses down the extension plate 21, thereby driving the extension plate 21 to drive the second rotating shaft 20 to rotate, so that the electrostatic dust removal rod 17 is facing upward to absorb the dust generated during air cooling.

[0046] Example 5: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 A knocking assembly is horizontally arranged at one end of the first rotating shaft 12, and the knocking assembly includes a knocking rod 32. A through hole 31 is opened in the fixing frame 30, and the knocking rod 32 passes through the through hole 31. The fixing frame 30 is connected to a bracket 34 at one side of the through hole 31, and the bracket 34 and the fixing frame 30 are elastically connected through a second spring 33. A corrugated plate 29 is fixedly connected to one side of the rack 26, and one end of the knocking rod 32 passes through the through hole 31 and is arranged to fit the groove of the corrugated plate 29.

[0047] In this embodiment, a corrugated plate 29 is connected to one side of the rack 26. As the rack 26 moves downward, the corrugated plate 29 moves downward synchronously. A knocking rod 32 is slidably arranged in the fixed frame 30. One end of the knocking rod 32 faces the first rotating shaft 12, and the other end passes through the through hole 31 in the fixed frame 30. A second spring 33 is connected between the bracket 34 and the fixed frame 30. Since one end of the knocking rod 32 is in contact with the corrugated plate 29, as the corrugated plate 29 moves downward, the knocking rod 32 is driven to reciprocate in the horizontal direction to knock on the first rotating shaft 12, so that the dust on the bristles 15 is knocked off and then adsorbed in time by the electrostatic dust removal rod 17, thereby realizing the cleaning of the bristles 15 and ensuring the cleaning effect during subsequent glass dust removal, thereby ensuring the glass tempering treatment effect.

[0048] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0049] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
