Description

Technical Field

[0001] This invention belongs to the field of glass tempering technology, and particularly relates to a glass tempering device. Background Technology

[0002] Glass is an amorphous inorganic solid material formed by the cooling and solidification of molten silicate. With its transparency, hardness, chemical stability, insulation properties, and ability to be thermoformed into various shapes, it plays an extremely important and indispensable role in human life and industry. One type of glass possesses superior bending strength and impact resistance, more than four times that of ordinary glass. This type of glass is the special tempered glass widely used in building curtain walls, doors and windows, aerospace, vehicles, and ships.

[0003] Tempered glass is safety glass obtained by strengthening ordinary annealed glass. In the existing tempering process, sheet glass is conveyed sequentially to a high-temperature heating furnace and an air-cooled tempering furnace via conveyor rollers. The high-temperature heating furnace heats the cut glass to near its softening point (approximately 700°C), followed by rapid and uniform cooling in the air-cooled tempering furnace, thus obtaining tempered glass. However, inherent defects formed during glass production or transportation, combined with uneven temperature during heating or vibration during conveying, can easily cause the glass to shatter inside the high-temperature furnace or air-cooled tempering furnace. When the glass breaks in the heating furnace, the high temperature causes the glass fragments to melt and adhere together, forming blocky or net-like aggregates (similar to "syrup solidification"). This prevents the fragments from falling normally to the collection tank under their own weight, and the aggregates may also obstruct the operation of the conveyor rollers, forcing the production line to stop. Cleaning the glass aggregates in the high-temperature heating furnace requires cooling the equipment before reheating, a process that consumes a lot of energy and time, severely reducing production efficiency. Meanwhile, manual cleaning can easily cause mechanical damage to the precision conveyor rollers, further increasing maintenance costs. Summary of the Invention

[0004] In view of this, the present invention provides a glass tempering device that can shear broken glass so that glass fragments fall from the gap between two adjacent conveying rollers into a debris collection trough.

[0005] To achieve the above objectives, the present invention provides the following technical solutions.

[0006] 1. Glass tempering equipment, including a conveying line and a heating furnace installed on the conveying line for heating glass, the conveying line including conveying rollers arranged in rows for conveying sheets of glass, with gaps between adjacent conveying rollers; also including a shearing mechanism and a hot furnace debris collection trough installed in the heating furnace; the shearing mechanism shears broken glass so that glass fragments fall from the gap between adjacent conveying rollers into the hot furnace debris collection trough.

[0007] This application, through the design of the heating and softening mechanism, shearing mechanism, and hot furnace debris collection trough in the heating furnace, can automatically shear broken glass inside the furnace, forming smaller glass fragments that can fall through the gaps in the conveyor rollers, thus achieving automated cleaning. This avoids the significant energy and time wasted by downtime in handling broken glass, thereby ensuring the production efficiency of tempered glass.

[0008] 2. Based on technical solution 1, the shearing mechanism includes multiple scissors arranged in a row; when the glass breaks, the rows of scissors cut the glass to break it into glass fragments.

[0009] 3. Based on technical solution 2, two adjacent shears are positioned opposite each other so that the two opposite force-bearing surfaces of the glass experience the same force when being sheared.

[0010] 4. Based on technical solution 1, it also includes a lifting mechanism. After the shearing mechanism shears the glass, the lifting mechanism raises the conveying rollers that are spaced apart to increase the gap between two adjacent conveying rollers.

[0011] 5. Based on technical solution 4, the lifting mechanism includes a lifting cylinder and a lifting housing. The spaced conveying rollers are rotatably mounted on the lower side of the lifting housing. The lifting cylinder drives the lifting housing to move upward, so that the lifting housing lifts the spaced conveying rollers.

[0012] 6. Based on technical solution 1, the conveying line also includes a roller drive mechanism for driving the conveying rollers to rotate. The roller drive mechanism includes a roller drive motor, a transmission shaft, and a transmission belt. The transmission shaft is arranged parallel to one side of the row of conveying rollers. The roller drive motor can drive the transmission shaft to rotate. There are multiple transmission belts, each corresponding to one of the conveying rollers. One end of each transmission belt is fitted onto the transmission shaft, and the other end is fitted onto the corresponding conveying roller. When the roller drive motor drives the transmission shaft to rotate, the transmission shaft drives the conveying rollers to rotate through the transmission belts, so that the conveying rollers convey sheets of glass.

[0013] 7. Based on technical solution 1, each conveying roller is fitted with a rotatable roller baffle.

[0014] 8. Based on technical solution 7, the outer surface of the roller baffle is provided with a friction surface.

[0015] 9. Based on technical solution 8, the friction surface is a barb array arranged on the outer surface of the roller baffle.

[0016] 10. Based on technical solution 1, it also includes an air-cooled furnace installed on the conveying line for cooling the glass, and the air-cooled furnace is equipped with a cold furnace debris collection trough for collecting glass fragments. Attached Figure Description

Detailed Implementation

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 1 , Figure 2 , Figure 3 and Figure 8 This embodiment of a glass tempering equipment is mainly used to perform a strengthening process on ordinary annealed glass by sequentially heating at high temperatures and rapidly cooling, thereby obtaining tempered glass with strong bending strength and impact resistance. Combined with... Figure 1 , Figure 3 and Figure 8 The glass tempering equipment in this embodiment includes a conveying line 1, a heating furnace 2, an air-cooling furnace 3, a shearing mechanism 4, a hot furnace debris collection trough 5, and a cold furnace debris collection trough 9. The conveying line 1 is used to convey sheets of glass. The heating furnace 2 and the air-cooling furnace 3 are sequentially arranged along the conveying direction of the glass sheets on the conveying line 1, wherein the conveying line 1 passes through the heating furnace 2 and the air-cooling furnace 3, so that the glass sheets pass through the heating furnace 2 and the air-cooling furnace 3 in sequence. The heating furnace 2 is used to heat and soften the glass, and the air-cooling furnace 3 is used to rapidly cool the glass. Figure 3 Both the shearing mechanism 4 and the hot furnace debris collection trough 5 are located inside the heating furnace 2. The shearing mechanism 4 is used to shear broken glass pieces, and the hot furnace debris collection trough 5 is located below the conveying line 1 to collect the sheared glass fragments. Figure 8 The cold furnace debris collection trough 9 is located inside the air-cooled furnace 3 and below the conveying line 1, and is used to collect the broken glass shards.

[0027] During the operation of the glass tempering equipment, conveyor line 1 transports sheets of glass, which are then sequentially heated and softened at high temperature in furnace 2 and cooled by air in furnace 3. When a glass sheet breaks in furnace 2 due to conveying vibration or internal stress, conveyor line 1 stops transporting the glass sheet, and furnace 2 continues to heat the broken glass sheet until it is softened to a shearable state. Shearing mechanism 4 shears the broken glass sheet to form smaller glass fragments. These fragments fall from conveyor line 1 under their own weight into hot furnace debris collection trough 5, where they are collected. When a glass sheet shatters in air-cooled furnace 3, the fragments are relatively small and can directly pass through the gaps in conveyor line 1 into cold furnace debris collection trough 9, eliminating the need for shearing mechanism 4 for collection.

[0028] Therefore, through the design of the heating and softening mechanism 4 in the heating furnace 2, the shearing mechanism 4, and the hot furnace debris collection tank 5, broken glass pieces inside the heating furnace 2 can be sheared into smaller glass fragments, making them small enough to fall through the gaps in the conveyor line 1, thus achieving automated cleaning. The cold furnace debris collection tank 9 can directly collect glass shards shattered inside the air-cooled furnace 3, avoiding the significant energy and time wasted by downtime for broken glass processing, thereby ensuring the production efficiency of tempered glass.

[0029] See Figure 1 The conveying line 1 in this embodiment includes a row of conveying rollers 11 for conveying sheet glass and a roller drive mechanism 12 for driving the conveying rollers 11 to rotate. The roller drive mechanism 12 is driven to the conveying rollers 11 and is used to drive the conveying rollers 11 to rotate, thereby realizing the conveying of sheet glass.

[0030] For details, see Figure 1 and Figure 2 In this embodiment, the conveying roller 11 is designed with multiple sections, with one section located in front of the heating furnace 2, inside the heating furnace 2, inside the air-cooling furnace 3, and behind the air-cooling furnace 3. Since the glass sheet needs to be heated for a certain time in the heating furnace 2 and cooled for the required time in the air-cooling furnace 3, a segmented design is adopted to facilitate control of the rotation speed of the conveying rollers 11 in the heating furnace 2 and the air-cooling furnace 3, thereby effectively controlling the dwell time of the glass sheet. A gap is left between adjacent conveying rollers 11 in the heating furnace 2 and the air-cooling furnace 3 to allow glass fragments to fall off. In this embodiment, the conveying roller 11 is a ceramic roller, which can prevent scratches on the glass surface during glass sheet transport.

[0031] See Figure 2 , Figure 3 and Figure 5 The roller drive mechanism 12 of this embodiment includes a roller drive motor 121, a drive shaft 122, and a drive belt 123. The drive shaft 122 is arranged parallel to one side of the rows of conveyor rollers 11, that is, the direction of the axis of the drive shaft 122 is perpendicular to the direction of the axis of the conveyor rollers 11. The roller drive motor 121 drives the drive shaft 122 to rotate via the belt. Multiple drive belts 123 are provided, each corresponding to one of the conveyor rollers 11. One end of each drive belt 123 is fitted onto the drive shaft 122, and the other end is fitted onto the corresponding conveyor roller 11 and tensioned. Since the direction of the axis of the drive shaft 122 is perpendicular to the direction of the axis of the conveyor rollers 11, the drive belt 123 is in a twisted state at this time. When the roller drive motor 121 drives the drive shaft 122 to rotate, the drive shaft 122 drives multiple conveyor rollers 11 to rotate simultaneously via the drive belt 123, thereby realizing the conveying of the glass sheet. This design reduces the design of the roller drive motor 121, simplifying the overall structure and control complexity.

[0032] See Figure 2 , Figure 3 and Figure 4 In this embodiment, the shearing mechanism 4 includes two sets of cutters symmetrically arranged on the upper and lower sides of the conveying line 1. Each set of cutters includes a drive cylinder 41, a mounting plate 42, a guide rod 43, and a row of cutters 44 arranged on the mounting plate 42. The piston rod of the drive cylinder 41 is connected to the mounting plate 42 and can drive the mounting plate 42 to move up and down. One end of the guide rod 43 is installed on the side of the mounting plate 42 facing away from the cutters 44, and the other end is slidably installed on the outer shell 21 of the heating furnace 2. Figure 4 The two rows of cutting blades 44 correspond one-to-one and form scissors, thus creating multiple scissors arranged in a row. Combined with... Figure 2When the glass sheet inside the heating furnace 2 is broken, the upper and lower drive cylinders 41 simultaneously drive the corresponding mounting plates 42, causing the mounting plates 42 to move the cutters 44 on them towards each other. The cutter 44 on the lower side of the conveying line 1 passes through the gap between the conveying rollers 11 and simultaneously squeezes the broken glass sheet with the cutter 44 on the upper side of the conveying line 1, performing a shearing action. The glass sheet is cut into fragments under multiple shearing forces and then falls from the gap between the two conveying rollers 11 into the furnace debris collection trough 5 on the lower side of the conveying line 1.

[0033] See Figure 4 In this embodiment, adjacent shears are arranged facing each other, meaning that adjacent cutters 44 in the same row face opposite directions. This ensures that when all shears are cutting the glass sheet, the glass sheet experiences relatively balanced force on its two opposing surfaces, guaranteeing that the glass sheet remains stationary during cutting and facilitating the cutting process. This avoids the problem of the glass sheet moving to the edge of the conveyor roller 11 due to unidirectional shearing force, and curling at the edge under the constraint of the outer casing 21, which would increase the difficulty of cutting the glass sheet.

[0034] See Figure 4 In this embodiment, the furnace debris collection tank 5 is mainly composed of multiple rectangular tanks 51 arranged side by side, with a gap between two adjacent rectangular tanks 51 for the cutter 44 to move. One side of each of the multiple rectangular tanks 51 is connected as one unit, so that after a certain amount of glass fragments are collected in the furnace debris collection tank 5, they can be simultaneously removed from the heating furnace 2 and the glass fragments can be cleaned.

[0035] See Figure 3 and Figure 5 The glass tempering equipment in this embodiment also includes a lifting mechanism 6 for lifting the conveying rollers 11. After the shearing mechanism 4 shears the glass, the lifting mechanism 6 lifts the conveying rollers 11 that are spaced apart, so as to increase the gap between two adjacent conveying rollers 11 for the glass fragments to fall, and prevent the sheared glass fragments from being horizontally mounted on the conveying rollers 11 due to lateral force, so that they cannot fall into the hot furnace debris collection tank 5 below through the gap between the conveying rollers 11.

[0036] Specifically, see Figure 5 In this embodiment, the outer shell 21 of the heating furnace 2 is divided into upper and lower shells. Two sets of cutters are respectively disposed within the two shells and slidably connected to the corresponding shells. Combined with... Figure 5The lifting mechanism 6 includes four lifting cylinders 61, which are respectively arranged at the four apex corners of the upper outer shell 21 of the heating furnace 2, wherein the upper outer shell 21 of the heating furnace 2 serves as the lifting shell. The cylinder body of the lifting cylinder 61 is connected to the lifting shell, and the piston rod of the lifting cylinder 61 is fixedly connected to the lower outer shell 21 of the heating furnace 2. The conveying rollers 11 inside the heating furnace 2 are divided into two parts, one part of which is rotatably mounted on the lower side of the lifting shell, and the other part of which is rotatably mounted on the lower outer shell 21. When the shearing mechanism 4 shears the glass, oil is supplied to the four lifting cylinders 61. The piston rods of the lifting cylinders 61 extend and generate an upward supporting force on the cylinder body and the lifting shell. The lifting shell drives the spaced-apart conveying rollers 11 to rise, thereby increasing the gap between the lower conveying rollers 11. At this time, glass fragments can fall from the larger gap into the furnace debris collection trough 5.

[0037] Obviously, by using the separate design of the outer shell 21 and the conveying rollers 11 of the heating furnace 2, and by setting up the lifting cylinder 61, some of the conveying rollers 11 can be lifted, thereby increasing the space for glass fragments to fall. It should also be noted that since the rows of conveying rollers 11 inside the heating furnace 2 are divided into two parts, each part of the conveying rollers 11 corresponds to a set of roller shaft drive mechanisms 12, and is driven to rotate by the corresponding roller shaft drive mechanism 12.

[0038] See Figure 3 , Figure 5 , Figure 6 and Figure 7 In this embodiment, each conveying roller 11 is fitted with a rotatable roller baffle 7. When the glass sheet is sheared and before the conveying roller 11 is lifted, the roller baffle 7 is rotated to face upwards, and the lifting housing 21 lifts the conveying roller 11. At this time, some glass fragments may be lifted to a certain height and then fall onto the conveying roller 11 below under gravity. The roller baffle 7 can prevent the falling glass fragments from directly impacting the ceramic conveying roller 11. That is, the roller baffle 7 protects the ceramic conveying roller 11 and ensures that the ceramic conveying roller 11 will not be damaged or broken. When the lifted conveying roller 11 returns to its original position, all roller baffles 7 rotate and return to their original position, so that the ceramic surface of the conveying roller 11 faces upwards to convey intact glass sheets.

[0039] See Figure 6 and Figure 7This embodiment also includes a baffle drive mechanism 8 for driving the rotation of the roller baffles 7. The baffle drive mechanism 8 has a structure basically the same as the roller drive mechanism 12. The baffle drive mechanism 8 also includes multiple baffle rotating shafts 81, which correspond one-to-one with and are connected to the roller baffles 7. The transmission belt in the baffle drive mechanism 8 is sleeved on the baffle rotating shafts 81 and the transmission shaft 122. When the drive motor in the baffle drive mechanism 8 drives the transmission shaft to rotate, the transmission shaft drives the multiple baffle rotating shafts 81 to rotate simultaneously through the transmission belt, thereby driving the multiple roller baffles 7 to rotate synchronously.

[0040] Among them, see Figure 6 and Figure 7 In this embodiment, the roller baffle 7 is arc-shaped, and a support ring 71 is provided at each end of the roller baffle 7. The conveying roller 11 is inserted into the roller baffle 7 and is rotatably connected to the support ring 71 through a bearing.

[0041] Additionally, see Figure 6 and Figure 7 The outer surface of the roller baffle 7 is provided with a friction surface 72, specifically barbs arranged in an array on the outer surface of the roller baffle 7. Since the glass sheet is in a soft state when being sheared, under the constraint of the conveyor roller 11, the glass sheet may be cut in an arc shape and hang on the lifted conveyor roller 11, unable to fall normally. By setting barbs, the friction between the roller baffle 7 and the glass sheet is increased, thereby increasing the driving force of the roller baffle 7 on the glass sheet when it rotates. First, the lifted roller baffle 7 is driven to rotate, causing the glass fragments hanging on the upper conveyor roller 11 to fall onto the lower roller baffle 7. Then, the lower roller baffle 7 is driven to rotate, causing the glass fragments to fall into the furnace debris collection trough 5. This ensures that all glass fragments fall into the furnace debris collection trough 5 in an orderly manner.

[0042] In addition, since some of the glass fragments that fall into the lower hot furnace debris collection tank 5 may be stuck on the lower cutter 44, making it impossible to properly pull out the hot furnace debris collection tank 5 and remove the broken glass, after the upper conveyor roller 11 is reset, the cutter 44 above the conveyor line 1 can be driven to pass through the gap between the conveyor rollers 11 and cut the glass fragments that fall below the conveyor line 1 again, ensuring that all the glass falls into the hot furnace debris collection tank 5.

[0043] The following further explains the working process of the present invention to further demonstrate its working principle and advantages: When a piece of glass breaks inside the heating furnace 2 due to conveying vibration or internal stress, the conveying line 1 stops conveying the glass sheet, and the heating furnace 2 continues to heat the broken glass until it softens to a shearable state. The upper and lower drive cylinders 41 simultaneously drive the corresponding mounting plates 42, causing the cutters 44 on them to move towards each other. The cutter 44 on the lower side of the conveying line 1 passes through the gap between the conveying rollers 11 and simultaneously presses against the broken glass sheet with the cutter 44 on the upper side of the conveying line 1, performing a shearing action. The glass sheet is sheared into fragments under multiple shearing forces. The drive motor in the baffle drive mechanism 8 drives the transmission shaft 122 to rotate. The transmission shaft 122 drives multiple baffle shafts 81 to rotate simultaneously via the transmission belt 123, thereby causing the roller baffles 7 to rotate above the conveying rollers 11. Oil is supplied to the four lifting cylinders 61, causing the piston rods of the lifting cylinders 61 to extend and exert an upward supporting force on the cylinder body and lifting housing. The lifting housing drives the spaced-apart conveyor rollers 11 to rise, thereby increasing the gap between the lower conveyor rollers 11. First, the lifting roller baffle 7 is driven to rotate, causing the glass fragments hanging on the upper conveyor rollers 11 to fall onto the lower roller baffle 7. Then, the lower roller baffle 7 is driven to rotate, causing the glass fragments to fall into the furnace debris collection trough 5. The lifting cylinders 61 are unloaded, and the upper conveyor rollers 11 are reset. The cutter 44 above the conveyor line 1 is driven to pass through the gap between the conveyor rollers 11 and cut the glass fragments that have fallen below the conveyor line 1 again, ensuring that all the glass falls into the furnace debris collection trough 5. When the furnace debris collection trough 5 has collected a certain amount of glass fragments, the furnace debris collection trough 5 is removed from the furnace 2 and the glass fragments are cleaned.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions created by the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions created by the present invention without departing from the essence and scope of the technical solutions created by the present invention.
