Description

Technical Field

[0001] The invention relates to the technical field of glass tempering furnaces, and in particular to a glass tempering furnace. Background Art

[0002] A glass tempering furnace is a device specifically used for tempering glass, which is a special glass made through a heating and rapid cooling process. The characteristic of tempered glass is that compressive stress is formed on its surface, while tensile stress is maintained inside, which significantly improves its strength and safety. Tempered glass has higher impact resistance and compressive strength than ordinary glass, so it has been widely used in modern architecture, automobiles, home appliances, mobile phone screens and other fields. The working principle of a glass tempering furnace is: first, the glass is heated to close to its softening point, usually between 600 and 700 degrees Celsius, and then the surface of the glass is rapidly cooled by rapid cooling (usually using air or coolant), thereby generating strong surface compressive stress. This process not only enhances the strength of the glass, but also makes it better resistant to thermal shock. Modern glass tempering furnaces usually have a highly automated temperature control system that can accurately control the temperature and time of heating and cooling to ensure uniform and consistent tempering effect.

[0003] In the prior art, there is a Chinese invention with the publication number of "CN116040929A", a glass tempering furnace, comprising a feeding track, a heating chamber and a cooling chamber are sequentially arranged on the feeding track along the conveying direction of the feeding track, a plurality of feeding conveying rollers are arranged on the feeding track near the feeding end of the heating chamber, a plurality of discharging conveying rollers are arranged on the feeding track near the discharging end of the cooling chamber, a conveyor belt is arranged below the discharging conveying roller, the conveyor belt is arranged along the conveying direction of the feeding track, a collecting box is arranged at the discharging end of the conveyor belt, a cleaning mechanism 1 is arranged at the bottom of the discharging conveying roller, the cleaning mechanism 1 is located above the conveyor belt, the cleaning mechanism 1 is used to clean the discharging conveying roller so that the glass cullet particles adhered to the discharging conveying roller fall onto the conveyor belt, a cleaning mechanism 2 is arranged at the discharging end of the conveyor belt, the cleaning mechanism 2 is used to clean the conveyor belt so that the glass cullet particles adhered to the conveyor belt fall into the collecting box.

[0004] According to the instruction manual Figure 1As shown in the figure, the cleaning mechanism moves the slider to clean the glass residues adhered to the discharge conveyor rollers one by one. During the cleaning process, since the broken glass residues still maintain a high temperature, it must be cleaned carefully to avoid the broken glass from splashing. In order to prevent the fragments from splashing, the cleaning work needs to be completed slowly and carefully one by one on each discharge conveyor roller, which makes the entire cleaning process very time-consuming and complicated. However, this method will cause the glass residues on the innermost conveyor rollers to further cool and solidify due to the long waiting time for cleaning, which increases the difficulty of cleaning. At the same time, the entire cleaning process consumes a lot of time, prolongs the equipment maintenance cycle, and thus increases production costs. Summary of the invention

DETAILED DESCRIPTION

[0037] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example

[0039] like Figure 2 to Figure 8 As shown, this embodiment proposes a glass tempering furnace, including a conveying platform 11, a feeding platform 12 is fixedly provided on one side of the conveying platform 11, a heating chamber 13 and a cooling chamber 14 are sequentially provided on one side of the feeding platform 12 along the feeding direction, and the heating chamber 13 and the cooling chamber 14 are both arranged above the feeding platform 12;

[0040] The feeding platform 12 includes a feeding frame 21, and a plurality of supporting seats 22 are connected to the feeding frame 21. A first flip plate 231 and a second flip plate 232 are rotatably connected to two coaxial supporting seats 22, and two supporting rollers 24 are rotatably connected between the first flip plate 231 and the second flip plate 232.

[0041] The feeding frame 21 is fixedly connected with a first protective plate 251 and a second protective plate 252, and a scraping assembly for scraping the supporting roller 24 is connected between the first protective plate 251 and the second protective plate 252;

[0042] A protective unloading assembly is connected to the lower side of the scraper assembly;

[0043] A linkage gear 26 is fixedly connected to the side of each support roller 24 facing the second flip plate 232, a plurality of driving gears 27 are rotatably connected to the second protection plate 252, and a driving assembly for synchronously driving the plurality of driving gears 27 is connected to the side of each driving gear 27 facing the second flip plate 232 away from the driving gear 27;

[0044] The scraper assembly ensures that the cleaning task can be performed smoothly no matter which side of the support roller 24 is in working condition. The scraper plate 35 can slide stably along the axis of the limit column 32, which makes the scraping work of the scraper plate 35 on the surface of the support roller 24 more stable, thereby improving the cleaning effect. A scraper assembly is arranged between each group of support rollers 24, so that multiple support rollers 24 can work synchronously when cleaning needs occur, which significantly improves the cleaning efficiency and shortens the cleaning cycle, so that glass residues will not solidify on the support rollers 24, reducing the difficulty of cleaning the support rollers 24. In addition, the easy-to-replace design of the scraper plate 35 ensures that it can be quickly replaced when damaged, reducing the maintenance cost of the equipment. At the same time, in order to prevent the limit column 32 from being damaged and ensure its long-term stable operation, the design preferably configures a bellows for the limit column 32 to provide additional protection. Through these design optimizations, the operation of the equipment is more efficient and reliable;

[0045] In the protective unloading assembly, when the support roller 24 is turned over or replaced, the unloading plate 41 will turn around the positioning plate 42, and the glass residues trapped on the unloading plate will be discharged by means of the tilting effect. In daily work, the unloading plate can not only remove waste materials, but also effectively protect the support roller 24 below from damage. When the surface of the upper support roller is damaged, after the surface is cleaned, the support roller below can be quickly replaced without waiting for cooling, which can restore the equipment operation faster, reduce downtime, and thus improve production efficiency. The support spring 48 ensures that after the unloading plate is turned over, it can automatically reset without external force, continue to maintain the waste collection and guidance functions, and ensure stable and continuous operation of the equipment.

[0046] like Figure 3 to Figure 6 As shown, the scraper assembly includes two limit plates 31, each limit plate 31 is slidably connected between the first protective plate 251 and the second protective plate 252, two limit columns 32 are fixedly connected between the two limit plates 31, and the two limit columns 32 are slidably connected to the limit blocks 33, the limit blocks 33 are fixedly connected to the receiving blocks 34, and the receiving blocks 34 are fixedly connected to the two scraper plates 35;

[0047] Each support roller 24 is provided with a spiral scraper groove 241, and each scraper plate 35 abuts against the inner wall of the scraper groove 241;

[0048] The scraper assembly ensures that the cleaning task can be performed smoothly no matter which side of the support roller 24 is in working condition. The scraper plate 35 can slide stably along the axis of the limit column 32, which makes the scraping work of the scraper plate 35 on the surface of the support roller 24 more stable, thereby improving the cleaning effect. A scraper assembly is configured between each group of support rollers 24, so that multiple support rollers 24 can work synchronously when cleaning needs occur, which significantly improves the cleaning efficiency and shortens the cleaning cycle, so that glass residues will not solidify on the support rollers 24, reducing the difficulty of cleaning the support rollers 24. In addition, the easy-to-replace design of the scraper plate 35 ensures that it can be quickly replaced when damaged, reducing the maintenance cost of the equipment. At the same time, in order to prevent the limit column 32 from being damaged and ensure its long-term stable operation, the design preferably configures a bellows for the limit column 32 to provide additional protection. Through these design optimizations, the operation of the equipment is more efficient and reliable.

[0049] like Figure 3 to Figure 6 As shown, a reset cylinder 36 is connected directly below each limit block 33, and each reset cylinder 36 is rotatably connected between the first protective plate 251 and the second protective plate 252. A rotary gear 37 is fixedly connected between the end of the reset cylinder 36 facing the second flip plate 232 and the second flip plate 232, and a transmission gear 38 is meshed on the lower side of the rotary gear 37;

[0050] The first synchronous wheels 39 are fixedly connected to the same side of the driving gear 27 and the transmission gear 38, and the first synchronous belts 310 are meshed on the two first synchronous wheels 39;

[0051] A transmission column 331 is fixedly connected to the lower side of the limit block 33, and a spiral reset groove 361 is provided on the reset cylinder 36. The spiral direction of the reset groove 361 is opposite to the scraper groove 241, and the transmission column 331 abuts against the inner wall of the reset groove 361;

[0052] By meshing the rotary gear 37 with the transmission gear 38, the special spiral structure of the reset groove 361 is utilized to drive the transmission column 331 to slide along the reset groove 361, thereby completing multiple scraping operations without the need for an extra motor. This simple mechanical transmission replaces the traditional motor drive, which not only improves the efficiency of the scraping operation, but also reduces energy consumption and maintenance costs. Since the equipment structure is more concise and the system failure rate is lower, the maintenance cycle of the equipment is shortened and the maintenance cost is greatly reduced. Therefore, the use cost of the equipment is reduced, the cleaning effect of the support roller 24 is significantly improved, the cleaning difficulty is reduced, and the overall operation efficiency of the equipment is improved.

[0053] like Figure 5 As shown, the side of the feeding rack 21 close to the first protective plate 251 is fixedly connected to the lifting cylinder 311, the telescopic shaft of the lifting cylinder 311 is fixedly connected to the lifting plate 312, and the lifting plate 312 is fixedly connected to one end of each limit plate 31 close to the first protective plate 251;

[0054] By precisely controlling the telescopic shaft through the lifting electric cylinder 311, the telescopic distance of the scraper plate 35 can be precisely adjusted, so that the scraper plate 35 slides along the inner wall of the scraper trough 241 and adjusts its height. This control not only facilitates the scraper plate 35 to perform multiple scraping operations, but also provides convenience during equipment maintenance. Through this mechanism, the scraper plate 35 can automatically reset, maintain continuous working efficiency, and provide a quick operation method for subsequent equipment maintenance or debugging.

[0055] like Figure 3 and Figure 7-Figure 8 As shown, the protective unloading assembly includes a unloading plate 41, two positioning plates 42 are rotatably connected to the lower side of the unloading plate 41, two positioning columns 43 are fixedly connected to the lower side of the positioning plate 42, and each positioning block 44 is fixedly connected to the lower side of each positioning column 43, and the positioning blocks 44 are fixedly connected to the feeding rack 21;

[0056] The positioning plate 45 is slidably connected to the two positioning posts 43, each slider 46 is slidably connected to each positioning post 43, and the support plate 47 is hinged between each slider 46 and the unloading plate 41;

[0057] Each support spring 48 is sleeved on each positioning column 43, and both ends of each support spring 48 are respectively in contact with the positioning block 44 and the positioning plate 45;

[0058] In the protective unloading assembly, when the support roller 24 is turned over or replaced, the unloading plate 41 will turn around the positioning plate 42, and the glass residues trapped on the unloading plate will be discharged by means of the tilting effect. In daily work, the unloading plate can not only remove waste materials, but also effectively protect the support roller 24 below from damage. When the surface of the upper support roller is damaged, after the surface is cleaned, the support roller below can be quickly replaced without waiting for cooling, which can restore the equipment operation faster, reduce downtime, and thus improve production efficiency. The support spring 48 ensures that after the unloading plate is turned over, it can automatically reset without external force, continue to maintain the waste collection and guidance functions, and ensure stable and continuous operation of the equipment.

[0059] like Figure 3 to Figure 5 and Figure 7 As shown, a plurality of garbage bins 51 are slidably connected to the feeding rack 21, and each garbage bin 51 is respectively arranged between two discharge plates 41 or between the discharge plate 41 and the side wall of the feeding rack 21;

[0060] Through the design of the garbage bin 51, when the unloading plate 41 is tilted, the glass waste on the unloading plate 41 can be effectively collected to prevent the waste from falling on the ground. This not only keeps the working environment clean, but also facilitates the subsequent centralized treatment of waste, reducing the cleaning trouble caused by the scattered waste. At the same time, this design significantly reduces the labor intensity of workers, so that they no longer need to spend a lot of time and energy to clean up the waste on the ground, thereby improving work efficiency and optimizing working conditions.

[0061] like Figure 3-4 As shown, the driving assembly includes a motor seat 61, the motor seat 61 is fixedly connected to a side of the feeding rack 21 close to the second protective plate 252, the driving motor 62 is fixedly connected to the motor seat 61, and the driving shaft of the driving motor 62 is fixedly connected to the second synchronous wheel 63;

[0062] Each driving gear 27 is fixedly connected to each third synchronous wheel 64 on one side facing the motor base 61, and the second synchronous belt 65 is meshed with the second synchronous wheel 63 and a plurality of third synchronous wheels 64;

[0063] By using a single drive motor 62, the system can rotate multiple support rollers 24 synchronously through the drive gear 27, thereby avoiding the complex structure that requires multiple independent motors. This design not only effectively reduces the number of drive motors 62 purchased, reduces the initial cost of the equipment, but also optimizes the maintenance and operating costs of the equipment. While reducing the number of motors, it improves energy efficiency and equipment reliability, thereby reducing the long-term use cost of the equipment.

[0064] Working principle:

[0065] The glass tempering furnace is composed of a conveying table 11 and a feeding table 12. The feeding table is used to feed the glass into the heating chamber 13 and the cooling chamber 14. The feeding frame 21 on the feeding table and the support seat 22 jointly support and guide the glass plate. Two rotatably connected first flip plates 231 and second flip plates 232 are installed on the support seat. These first flip plates 231 and second flip plates 232 are used in conjunction with the support roller 24 to complete the transmission and processing of the glass. Between the heating chamber and the cooling chamber, the glass will be heated at high temperature and cooled at low temperature to ensure the tempering process of the glass;

[0066] During the glass transmission process, the glass may explode due to overcooling or overheating, and the high-temperature glass fragments may adhere to the surface of the support roller 24. In order to prevent these residues from affecting the quality of the glass and the operation of the equipment, the scraper assembly is designed to clean the residues on the surface of the support roller. The scraper assembly cooperates with the scraper trough 241 through the scraper plate 35 to clean the surface of the support roller. Through the rotation of the support roller 24, the scraper plate 35 cooperating with the scraper trough 241 can automatically clean the support roller 24;

[0067] The scraper plate 35 slides stably through the limit column 32 to ensure a smooth and efficient scraping process. A scraper assembly is arranged between each set of support rollers 24 to ensure that when the support rollers on either side need to be cleaned, the cleaning task can be performed synchronously, significantly improving the cleaning efficiency, shortening the cleaning cycle, and preventing the residue from solidifying;

[0068] The scraper assembly is controlled by a mechanical transmission system. Each limit block 33 is connected to a reset cylinder 36, and the scraper plate 35 slides along the limit column through the spiral reset groove 361 to complete the scraping action, so that a single scraper plate 35 can perform multiple round trips on a single support roller 24, thereby improving the cleaning effect of the support roller 24;

[0069] The lifting electric cylinder 311 on the feeding frame 21 adjusts the height of the scraper plate 35 by precisely controlling the telescopic shaft, and is used to control the scraper plate 35 to be in three working states, namely, scraping operation, stopping operation and resetting operation;

[0070] The protective unloading assembly includes a unloading plate 41, which rotates through a positioning plate 42. When the support roller 24 is turned over or replaced, the unloading plate 41 will tilt, and the glass residue will be discharged in the tilted direction by its own gravity. The unloading plate 41 is automatically reset after the cleaning is completed through a support spring 48, ensuring that the cleaning work is continuous and effective, and protecting the support roller 24 moved below the unloading plate 41.

[0071] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
