Abstract
Description
Technical Field
[0001] This utility model relates to the field of flat glass processing technology, specifically a flat glass tempering frame. Background Technology
[0002] In the glass manufacturing industry, flat glass is widely used, from doors and windows and curtain walls in the building field to glass tabletops and cabinet doors in home furnishings, and displays in electronic devices. As the demand for flat glass from various industries continues to increase, the requirements for its quality and performance are also increasing. Tempered glass has become a popular product in the market due to its advantages such as high strength, high safety and good thermal stability, which has promoted the rapid development of flat glass tempering technology.
[0003] Currently, common tempering frames for flat glass mainly consist of a frame, a heating device, a cooling device, and a conveying device. The heating device generally uses resistance wire heating or gas heating. Taking resistance wire heating as an example, the resistance wire is evenly distributed in the heating chamber. The resistance wire is heated by the current, which in turn heats the glass placed on the conveying device. When the current passes through the resistance wire, electrical energy is converted into heat energy and transferred to the glass through heat radiation and heat conduction, so that the glass gradually heats up to the softening point. The cooling device is usually used after the glass is heated. A fan blows cold air onto the glass surface, which cools the glass surface rapidly and causes it to shrink. Stress is formed inside the glass, which achieves the tempering process. The conveying device is mostly a roller conveyor. The roller is driven by a motor to rotate, which moves the glass through the heating zone and cooling zone in sequence in the tempering frame to complete the tempering process.
[0004] Existing tempering frames for flat glass have significant shortcomings in adapting to flat glass of different lengths. The heating zone size of the tempering frame is fixed, and the layout of the heating elements is designed according to the specific glass size. When dealing with longer flat glass, the two ends of the glass may not be effectively heated or cooled, resulting in inconsistent tempering effect of the glass as a whole. To address this, we propose a tempering frame for flat glass. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5 This embodiment provides a technical solution: a flat tempered glass frame, including a frame 1. A control switch group 15 is provided on the front side of the frame 1, with its input terminal electrically connected to an external power source. An electric roller conveyor 14 is provided between the front and rear inner walls of the frame 1, with its input terminal electrically connected to the output terminal of the control switch group 15. A cooling chamber 10 is provided inside the left end between the front and rear inner walls of the frame 1. A cooling pipe 11 is provided in the middle of the upper side wall of the cooling chamber 10, and a blower chamber 12 is provided at the lower end of the cooling pipe 11. The blower chamber 12 is located inside the cooling chamber 10, and its lower end has evenly distributed nozzles. A blower 13 is installed on the upper side of the cooling chamber 10. The air outlet of the blower 13 is fixedly connected to the upper end of the cooling pipe 11. The input end of the blower 13 is electrically connected to the output end of the control switch group 15. When the glass is heated to a suitable temperature, the electric roller conveyor 14 transports the glass to the bottom of the cooling chamber 10. The control switch group 15 starts the blower 13. The blower 13 sends air into the air chamber 12 through the cooling pipe 11, and then sprays it out from the nozzles evenly distributed at the lower end of the air chamber 12 to cool the glass quickly. The cold air quickly impacts the glass surface, causing the glass surface to cool down and shrink rapidly, while the inside is still in a relatively high temperature state, thereby forming stress inside the glass to achieve tempering treatment. This facilitates the tempering treatment of flat glass and also includes a heating component 2.
[0026] Heating assembly 2 includes a left heating chamber 21, a slide rail 22, a right heating chamber 23, a left heating frame 24, and a right heating frame 27. The left heating chamber 21 is located in the middle between the front and rear inner walls of the frame 1. Symmetrically distributed mounting plates 6 are located at the rear end of the frame 1. A lead screw 7 is rotatably connected between the two mounting plates 6. The right rear end of the right heating chamber 23 is threadedly connected to the lead screw 7. A motor 5 is mounted on the left side of the mounting plate 6. The output shaft of the motor 5 is fixedly connected to the center of the left end face of the lead screw 7. The input end of the motor 5 is electrically connected to the output end of the control switch group 15. Guide plates 8 are provided on the right ends of both the front and rear sides of the right heating chamber 23. Guide grooves 9 are opened on the right ends of both the front and rear inner walls of the frame 1. The guide plates 8 are slidably connected to the adjacent guide grooves 9. The left heating chamber... The left heating chamber 21 has a slide rail 22 inside, and a right heating chamber 23 is slidably connected inside the slide rail 22. An adjustable left heating frame 24 is located inside the left heating chamber 21. The top wall of the left heating frame 24 has symmetrically distributed heating components. A right heating frame 27 is slidably connected inside the upper end of the left heating frame 24. Both the top walls of the left heating chamber 21 and the right heating chamber 23 have sliding columns 3. The left end of the left heating frame 24 is slidably connected to the outer arc surface of the left sliding column 3, and the right end of the right heating frame 27 is slidably connected to the outer arc surface of the right sliding column 3. An electric cylinder 4 is installed on the upper side of the left heating chamber 21. The telescopic end of the electric cylinder 4 passes through the upper side wall of the left heating chamber 21 and is fixedly connected to the upper side of the left heating frame 24. The input end of the electric cylinder 4 is electrically connected to the output end of the control switch group 15. The top wall of the heating frame 27 is provided with symmetrically distributed auxiliary heating components. The heating components 2 also include electrothermal silicon molybdenum rods 25 and extended electrothermal silicon molybdenum rods 28. The heating components are electrothermal silicon molybdenum rods 25, which are symmetrically distributed and installed on the top wall of the left heating frame 24. The auxiliary heating components are extended electrothermal silicon molybdenum rods 28, which are symmetrically distributed and installed on the top wall of the right heating frame 27. The input terminals of both the electrothermal silicon molybdenum rods 25 and the extended electrothermal silicon molybdenum rods 28 are electrically connected to the output terminals of the control switch group 15. The heating components 2 also include reflectors 26. The top walls of both the left heating frame 24 and the right heating frame 27 are provided with reflectors 26 (both reflectors 26 are aluminum-plated reflectors). When using this flat glass tempering frame, first place the flat glass to be tempered on... The glass is placed on an electric roller conveyor 14. The equipment is started via control switch group 15, and the electric roller conveyor 14 begins operation, smoothly conveying the glass to below the heating assembly 2. At this time, control switch group 15 controls motor 5 to start, and motor 5 drives lead screw 7 to rotate. Since the right heating chamber 23 is threadedly connected to lead screw 7, and guide plate 8 cooperates with guide groove 9, the right heating chamber 23 will move horizontally along the central axis of lead screw 7 within slide rail 22, thereby adjusting the distance between the left and right heating chambers according to the size of the glass, ensuring that the glass can be heated evenly. During the movement of the right heating chamber 23, the sliding column 3 on the top wall of the right heating chamber 23 will pull the right heating frame 27 to slide inside the upper end of the left heating frame 24. Then, control switch group 15 controls electric cylinder 4 to operate.The telescopic end of the electric cylinder 4 drives the left heating frame 24 to move up and down along the left sliding column 3, thereby adjusting the distance between the left heating frame 24 and the glass. Simultaneously, the right heating frame 27 slides along the right sliding column 3 as the left heating frame 24 moves, adapting to glass of different thicknesses. After the position is adjusted, the control switch group 15 connects the power supply to the electrothermal silicon molybdenum rod 25 and the extended electrothermal silicon molybdenum rod 28, which begin to heat up, heating the glass. The reflectors 26 on the top walls of the left and right heating frames 24 reflect heat onto the glass, improving heating efficiency, reducing heat loss, and making the glass heated more evenly. The size of the heating chamber can be adjusted according to the length of flat glass. The reflectors 26 also reflect the heat from the heating components onto the glass, improving heating efficiency, reducing heat loss, and making the glass heated more evenly.
[0027] The working principle of the flat glass tempering rack provided by this utility model is as follows: When using the flat glass tempering rack, firstly, the flat glass to be tempered is placed on the electric roller conveyor 14. The equipment is started by controlling the switch group 15, and the electric roller conveyor 14 starts to run, smoothly conveying the glass to the bottom of the heating component 2. At this time, the control switch group 15 controls the motor 5 to start, and the motor 5 drives the lead screw 7 to rotate. Since the right heating chamber 23 is threadedly connected to the lead screw 7, and the guide plate 8 cooperates with the guide slide 9, the right heating chamber 23 will move horizontally along the central axis of the lead screw 7 in the slide rail 22, thereby adjusting the distance between the left and right heating chambers according to the size of the glass, ensuring that the glass can be heated evenly. During the movement of the right heating chamber 23, the sliding column 3 on the top wall of the right heating chamber 23 will pull the right heating rack 27 to slide inside the upper end of the left heating rack 24. Then, the control switch group 15 controls the electric cylinder 4 to work, and the telescopic end of the electric cylinder 4 drives the left heating rack 24 to move up and down along the left sliding column 3, thereby... Adjust the distance between the left heating frame 24 and the glass. At the same time, the right heating frame 27 will slide on the right-side sliding column 3 as the left heating frame 24 moves to accommodate glass of different thicknesses. After the position is adjusted, the control switch group 15 connects the power supply to the electric heating silicon molybdenum rod 25 and the extended electric heating silicon molybdenum rod 28. They start to heat up and heat the glass. The reflector plate 26 on the top wall of the left heating frame 24 and the right heating frame 27 can reflect heat onto the glass, improve heating efficiency, reduce heat loss, and make the glass heated more evenly. When the glass is heated to a suitable temperature, the electric roller conveyor 14 transports the glass to the bottom of the cooling chamber 10. The control switch group 15 starts the blower 13. The blower 13 sends air into the air blowing chamber 12 through the cooling pipe 11, and then sprays it out from the nozzles evenly distributed at the bottom of the air blowing chamber 12 to quickly cool the glass. The cold air quickly impacts the glass surface, causing the glass surface to cool down and shrink rapidly, while the inside is still in a relatively high temperature state, thereby forming stress inside the glass and achieving tempering treatment.
[0028] It is worth noting that the electrothermal silicon molybdenum rod 25 and the extended electrothermal silicon molybdenum rod 28 disclosed in the above embodiments can both be GM6 / 8-180 models, the electric cylinder 4 can be an MME series electric cylinder, the motor 5 can be a MI NASA6 series servo motor, the blower 13 can be a GL200-4 type centrifugal blower, the electric roller conveyor 14 can be a DryLi nD W series, and the control switch group 15 is provided with control buttons that correspond one-to-one with the electrothermal silicon molybdenum rod 25, the extended electrothermal silicon molybdenum rod 28, the electric cylinder 4, the motor 5, the blower 13, and the electric roller conveyor 14 and are used to control their switching.
