Description

Technical Field

[0001] This invention relates to the field of glass tempering production technology, and in particular to a glass tempering furnace. Background Technology

[0002] Currently, in the field of glass deep processing, tempered glass, due to the mechanical structure formed by the surface compressive stress and internal tensile stress, has high strength and impact resistance, and is widely used in building curtain walls, car windows, electronic displays and other scenarios. The physical tempering method, which involves heating flat glass to near its softening point and then rapidly cooling it through glass tempering equipment, is the mainstream tempering process. However, existing glass tempering furnaces have significant shortcomings in cleaning functions, which directly affect product quality and production efficiency. Due to the lack of an effective pre-treatment cleaning mechanism, dust, oil, metal shavings, and other impurities remaining on the surface of tempered glass can penetrate into the glass surface during high-temperature heating, causing defects such as blurring and spots. This not only reduces the light transmittance and aesthetics of the glass but also increases the difficulty of subsequent cleaning. Furthermore, the rollers used to transport glass within the tempering furnace operate in a high-temperature, dusty environment, making their surfaces highly susceptible to absorbing dust, glass shavings, and other contaminants. These impurities can then re-adhere to the glass surface during transport, causing scratches, indentations, and other quality problems. This leads to a decrease in the yield rate of finished tempered glass and increases production costs and material waste. In addition, existing tempering furnace cleaning processes largely rely on manual, periodic shutdowns for cleaning, which is not only time-consuming and labor-intensive but also fails to thoroughly remove stubborn impurities from inside the equipment and in the gaps between the rollers. This cannot meet the requirements of modern continuous production for stable product quality. Therefore, the existing equipment has certain deficiencies and shortcomings, necessitating its redesign. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a glass tempering furnace to more accurately resolve the problems described above.

[0004] This invention is achieved through the following technical solution: This invention proposes a glass tempering furnace, including a support frame. A first conveyor frame and a second conveyor frame are fixedly installed on both sides of the top of the support frame. Conveyor rollers are rotatably connected to the inner sides of the first and second conveyor frames in a linear arrangement with equal spacing. A tempering furnace body is fixedly installed between the inner sides of the first and second conveyor frames. Roller cleaning devices are movably installed on the outer surface of each conveyor roller in the first conveyor frame. The two ends of the roller cleaning devices are fixedly connected to the inner side of the first conveyor frame. A glass cleaning device is fixedly installed on the side of the roller cleaning device near the tempering furnace body inside the first conveyor frame. Positioning devices are fixedly installed at both ends of the front and rear sides of the top of the first conveyor frame. The roller cleaning device includes a rail frame, which is linearly arranged at equal intervals and fixedly installed at the bottom of the first conveyor frame. The rail frame is equipped with a drive mechanism inside, and a transmission mechanism is fixedly installed on one side of the drive mechanism. A cleaning mechanism is fixedly connected to the top of the transmission mechanism. The cleaning mechanism is movably sleeved on the outer surface of the conveyor roller inside the first conveyor frame. The glass cleaning device is installed on the outside of the drive mechanism near the tempering furnace body.

[0005] Furthermore, the driving mechanism includes a lead screw and a drive motor. The lead screw is rotatably connected to the inside of the rail frame, and the drive motor is fixedly installed at one end of the rail frame. The output end of the drive motor is fixedly connected to the end of the lead screw. A slider is threadedly connected to the outer surface of the lead screw, and the transmission mechanism is fixedly installed on the side of the slider close to the tempering furnace body.

[0006] Furthermore, the transmission mechanism includes a side rod and a rack. The cleaning mechanism is fixedly installed on the top of the slider. The side rod is fixedly installed on the side of the slider near the tempering furnace body. The rack is fixedly installed on the side of the rail frame near the tempering furnace body. A spur gear is rotatably connected to the top outer end of the side rod. A bevel gear is fixedly connected to the top of the spur gear. The bevel gear meshes with the cleaning mechanism. The spur gear meshes with the rack.

[0007] Furthermore, the cleaning mechanism includes a top rod, which is fixedly installed on the top of the slider. An annular rail is fixedly installed on the top of the top rod. A cleaning ring is slidably connected to the inner side of the annular rail. Cleaning brushes are fixedly connected at equal intervals to the inner side of the cleaning ring. A bevel gear ring is fixedly installed on one side of the cleaning ring. The bevel gear ring meshes with a bevel gear. The cleaning ring is sleeved on the outer surface of the conveyor roller. The inner side of the cleaning brushes is in close contact with the outer surface of the conveyor roller.

[0008] Furthermore, the overall side shape of the slider is convex, the overall internal cross-sectional shape of the rail frame is also convex, and a wear-resistant pad is fixedly connected to the outer surface of the slider.

[0009] Furthermore, the outer side of the cleaning ring is rotatably connected with balls at equal intervals, the outer side of the balls is in close contact with the inner wall of the annular rail, and the overall cross-sectional shape of the cleaning ring is U-shaped.

[0010] Furthermore, the glass cleaning device includes a connecting rod, which is fixedly installed on the outside of one of the sliders near the tempering furnace body. A concave frame is fixedly installed on the outer end of the connecting rod, and a scraping mechanism is fixedly connected to both the upper and lower ends of the outer side of the concave frame.

[0011] Furthermore, the scraping mechanism includes a fixed seat, which is fixedly installed on the upper and lower ends of the outer side of the concave frame. A first cylinder is fixedly installed in the middle of the fixed seat. The output end of the first cylinder passes through the fixed seat and is fixedly installed on a base plate. A glass cleaning scraper is fixedly installed on the inner side of the base plate. The glass cleaning scraper is located in the gap of the conveying roller.

[0012] Furthermore, the positioning device includes a side plate, which is fixedly installed on both ends of the front and back of the first conveyor frame. A second cylinder is fixedly installed on the outer end of the side plate, a third cylinder is fixedly installed on the top output end of the second cylinder, and a correction positioning plate is fixedly installed on the output end of the third cylinder.

[0013] Furthermore, a groove is provided at the lower inner end of the correction positioning plate, and positioning guide rollers are rotatably connected inside the groove in a linear arrangement at equal intervals.

[0014] The beneficial effects of this invention are: 1. During the application of this equipment, the drive motor drives the lead screw to rotate, causing the convex slider to move linearly along the rail frame. Through gear transmission, the cleaning ring rotates within the annular rail, realizing the dynamic brushing and cleaning of the surface of the conveyor roller by the cleaning brush. The lateral movement and rotation of the cleaning ring are synchronized, and cleaning can be started in real time before the glass is conveyed to the conveyor roller or after it is removed, without stopping the machine. Compared with traditional manual cleaning, it can continuously remove dust and debris from the surface of the conveyor roller during equipment operation, avoid secondary pollution of the glass, significantly reduce the amount of impurities, and improve the surface quality and finished product qualification rate of tempered glass. 2. During the application of this equipment, when the roller cleaning device near the tempering furnace is running, the slider drives the connecting rod to move the concave frame back and forth. The first cylinder on the frame pushes the glass cleaning scraper to fit against the glass surface. With the help of the positioning device to limit the lateral movement of the glass, the scraper can perform a horizontal reciprocating scraping operation. This design, together with the conveyor roller cleaning, forms a dual cleaning mechanism to specifically remove stubborn impurities from the glass surface. This compensates for the lack of pre-treatment cleaning in traditional tempering furnaces, ensuring that the glass surface entering the tempering furnace is clean and reducing defects such as blurriness and spots caused by impurities from the source. 3. During the application of this equipment, its positioning device adjusts the position and height of the positioning plate through the linkage of the second and third cylinders, and uses the positioning guide roller to roll and calibrate the glass position to ensure conveying accuracy. Each cleaning and positioning mechanism is linked by the control system, which can automatically adjust parameters according to the glass size to realize the full automation of the process from positioning and conveying roller cleaning to glass surface cleaning. Compared with traditional manual cleaning with downtime, this equipment can produce continuously, reduce downtime, improve production efficiency, and reduce labor costs. It can ensure the stability of cleaning and positioning, effectively reduce the probability of defective products, and meet the needs of modern high-efficiency production.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0018] A glass tempering furnace includes a support frame 1. A first conveyor frame 2 and a second conveyor frame 3 are fixedly installed on both sides of the top of the support frame 1. Conveyor rollers 4 are rotatably connected to the inner sides of the first conveyor frame 2 and the second conveyor frame 3 in a linear arrangement with equal spacing. A tempering furnace body 5 is fixedly installed between the inner sides of the first conveyor frame 2 and the second conveyor frame 3. Roller cleaning devices 6 are movably installed on the outer surface of each conveyor roller 4 inside the first conveyor frame 2. The two ends of the roller cleaning devices 6 are fixedly connected to the inner side of the first conveyor frame 2. A glass cleaning device 7 is fixedly installed on the side of the roller cleaning device 6 near the tempering furnace body 5 inside the first conveyor frame 2. Positioning devices 8 are fixedly installed at both ends of the front and rear sides of the top of the first conveyor frame 2. The roller cleaning device 6 includes a rail frame 61, which is linearly arranged at equal intervals and fixedly installed at the bottom of the first conveyor frame 2. A drive mechanism 62 is installed inside the rail frame 61, and a transmission mechanism 63 is fixedly installed on one side of each drive mechanism 62. A cleaning mechanism 64 is fixedly connected to the top of the transmission mechanism 63. The cleaning mechanism 64 is movably sleeved on the outer surface of the conveyor roller 4 inside the first conveyor frame 2. The glass cleaning device 7 is installed on the outside of the drive mechanism 62, near the tempering furnace body 5. During the application of this device, when glass is conveyed by the conveyor roller 4 of the first conveyor frame 2, the positioning device 8 adjusts the position of the correction positioning plate 84 through the second cylinder 82 and the third cylinder 83, and uses the positioning guide roller 86 to perform lateral calibration and limit on the glass, ensuring stable and centered conveying. Simultaneously, the drive mechanism 62 of the roller cleaning device 6 drives the lead screw 622 through the drive motor 621. The rotation causes the slider 623 to move linearly within the rail frame 61. As the slider 623 moves, it meshes with the rack 632 via the spur gear 633 of the transmission mechanism 63, driving the bevel gear 634 to rotate. This, in turn, drives the cleaning ring 643 of the cleaning mechanism 64 to slide and rotate within the annular rail 642. The cleaning brush 644 dynamically cleans the surface of the conveyor roller 4. When the glass is conveyed to one end near the tempering furnace body 5, the slider 623 of the glass cleaning device 7 drives the connecting rod 71 and the concave frame 72 to move. The first cylinder 732 pushes the glass cleaning scraper 734 to adhere to the glass surface. With the limiting of the positioning device 8, the upper and lower surfaces of the glass are scraped and cleaned. After cleaning and positioning, the glass enters the tempering furnace body 5 for tempering and is then output by the second conveyor frame 3. Throughout the process, all devices work together to achieve automated cleaning and positioning of the glass and the conveyor roller 4.

[0019] Combination Figures 1-8As shown, the drive mechanism 62 includes a lead screw 622 and a drive motor 621. The lead screw 622 is rotatably connected to the inside of the rail frame 61, and the drive motor 621 is fixedly installed at one end of the rail frame 61. The output end of the drive motor 621 is fixedly connected to the end of the lead screw 622. A slider 623 is threadedly connected to the outer surface of the lead screw 622. The transmission mechanism 63 is fixedly installed on the side of the slider 623 near the tempering furnace body 5. The transmission mechanism 63 includes a side rod 631 and a rack 632. The cleaning mechanism 64 is fixedly installed on the top of the slider 623. The side rod 631 is fixedly installed on the side of the slider 623 near the tempering furnace body 5, and the rack 632 is fixedly installed on the side of the rail frame 61 near the tempering furnace body 5. A spur gear 633 is rotatably connected to the top outer end of the side rod 631. A bevel gear 634 is fixedly connected to the top of the spur gear 633. The bevel gear 634 and the cleaning mechanism 64 are meshed together, and the spur gear 633 and the rack 632 are meshed together.

[0020] In the above-described embodiments of this application, during the application of this device, when the drive mechanism 62 is running, the drive motor 621 fixed at one end of the rail frame 61 starts, and its output end drives the lead screw 622 to rotate inside the rail frame 61. Since the lead screw 622 is threadedly connected to the slider 623, and the rail frame 61 and the slider 623 adopt a convex-shaped mating structure, the slider 623 is restricted to only move linearly along the rail frame 61. Therefore, the rotation of the lead screw 622 is converted into the linear displacement of the slider 623. When the slider 623 moves, it drives the cleaning mechanism 64 fixed on its top and the side rod 631 on the side to move synchronously. The spur gear 633 at the top outer end meshes with the rack 632 fixed on one side of the rail frame 61. During the movement of the slider 623, the spur gear 633 rotates due to the limiting effect of the rack 632, which in turn drives the bevel gear 634 fixedly connected to the spur gear 633 to rotate together. The bevel gear 634 meshes with the bevel ring 645 in the cleaning mechanism 64, transmitting the rotational power to the cleaning mechanism 64, causing the cleaning ring 643 to slide and rotate on the inner side of the annular rail 642, so that the cleaning brush 644 on the inner side of the cleaning ring 643 can dynamically clean the surface of the conveyor roller 4, thereby effectively removing impurities from the surface of the conveyor roller 4. Example 2

[0021] Combination Figures 4-8 and Figure 10As shown, the cleaning mechanism 64 includes a top rod 641, which is fixedly installed on the top of the slider 623. An annular rail 642 is fixedly installed on the top of the top rod 641. A cleaning ring 643 is slidably connected to the inner side of the annular rail 642. Cleaning brushes 644 are fixedly connected at equal intervals to the inner side of the cleaning ring 643. A bevel ring 645 is fixedly installed on one side of the cleaning ring 643. The bevel ring 645 and the bevel gear 634 are meshed together. The cleaning ring 643 is sleeved on the outer surface of the conveyor roller 4. The inner side of the cleaning brushes 644 is in close contact with the outer surface of the conveyor roller 4. The overall side shape of the slider 623 is convex. The overall internal cross-sectional shape of the rail frame 61 is also convex. Wear-resistant pads are fixedly connected to the outer surface of the slider 623. Ball bearings 646 are rotatably connected at equal intervals to the outer side of the cleaning ring 643. The outer side of the ball bearings 646 is in close contact with the inner wall of the annular rail 642. The overall cross-sectional shape of the cleaning ring 643 is concave.

[0022] In the above-described embodiments of the present application, during use, when the bevel gear 634 in the transmission mechanism 63 rotates, the bevel gear ring 645 in the cleaning mechanism 64 meshing with it rotates accordingly. Since the bevel gear ring 645 is fixedly installed on one side of the cleaning ring 643, it drives the cleaning ring 643 to slide inside the annular track 642. The balls 646 on the outer side of the cleaning ring 643 are in contact with the inner wall of the annular track 642, reducing the frictional resistance when the cleaning ring 643 slides, allowing it to move smoothly along the annular track 642. At the same time, the cleaning brushes 644, which are evenly distributed on the inner side of the cleaning ring 643, are in close contact with the outer surface of the conveyor roller 4. During the sliding process of the cleaning ring 643, the cleaning brushes 644 continuously clean the surface of the conveyor roller 4. The surface is wiped to remove dust, debris and other impurities. The top rod 641 is fixed to the top of the slider 623, supporting the annular rail 642 and ensuring the stability of the cleaning mechanism 64. The slider 623 and the rail frame 61 adopt a convex-shaped mating structure, which restricts the movement direction of the slider 623 and ensures that the cleaning ring 643 can clean the conveyor roller 4 along a straight trajectory. The wear-resistant pad on the outer surface of the slider 623 further reduces the wear between it and the rail frame 61 and extends the service life of the components. The concave cross-section design of the cleaning ring 643, combined with the structure of the ball bearing 646 and the annular rail 642, not only ensures the stability of the sliding of the cleaning ring 643, but also allows the cleaning ring 643 to be firmly fitted on the outer surface of the conveyor roller 4, achieving efficient cleaning.

[0023] Combination Figures 1-7As shown, the glass cleaning device 7 includes a connecting rod 71, which is fixedly installed on the outside of one of the sliders 623 near the tempering furnace body 5. A concave frame 72 is fixedly installed on the outer end of the connecting rod 71. A scraping mechanism 73 is fixedly connected to both the upper and lower ends of the outer side of the concave frame 72. The scraping mechanism 73 includes a fixed seat 731, which is fixedly installed on the upper and lower ends of the outer side of the concave frame 72. A first cylinder 732 is fixedly installed in the middle of the fixed seat 731. A base plate 733 is fixedly installed through the fixed seat 731. A glass cleaning scraper 734 is fixedly installed on the inner side of the base plate 733. The glass cleaning scraper 734 is located in the gap of the conveying roller 4.

[0024] In the above-described embodiments of the present application, during the application of this device, when the glass cleaning device 7 is working, the slider 623 closest to the tempering furnace body 5 moves under the action of the drive mechanism 62, and the connecting rod 71 fixedly connected to it drives the concave frame 72 to move laterally. The first cylinder 732 in the upper and lower fixed seats 731 on the outer side of the concave frame 72 is activated, and pushes the substrate 733 to move in the vertical direction through the output end, thereby driving the glass cleaning scraper 734 fixed on the inner side of the substrate 733 to move. Since the glass cleaning scraper 734 is located in the gap of the conveying roller 4, When the first cylinder 732 extends, the scraper can adhere to the upper and lower surfaces of the glass. At this time, the slider 623 continues to slide back and forth, driving the concave frame 72 and the scraper to move laterally back and forth. The scraping action of the scraper removes the dust, debris and other impurities remaining on the glass surface. During this process, the contact pressure between the scraper and the glass surface can be flexibly adjusted by extending and retracting the first cylinder 732, ensuring that the scraper can effectively remove impurities without damaging the glass during the cleaning process of glass of different thicknesses, thereby ensuring that the glass surface entering the tempering furnace is clean. Example 3

[0025] Combination Figures 1-5 and Figure 9 As shown, the positioning device 8 includes a side plate 81, which is fixedly installed on both ends of the front and back of the first conveyor frame 2. A second cylinder 82 is fixedly installed on the outer end of the side plate 81. A third cylinder 83 is fixedly installed on the top output end of the second cylinder 82. A correction positioning plate 84 is fixedly installed on the output end of the third cylinder 83. A groove 85 is opened on the lower inner side of the correction positioning plate 84. Positioning guide rollers 86 are rotatably connected inside the groove 85 in a linear arrangement at equal intervals.

[0026] In the above-described embodiments of this application, during the operation of the positioning device 8, the side plate 81 is fixed to both ends of the front and back of the first conveyor frame 2, providing stable support for the entire positioning structure. When the glass enters the first conveyor frame 2, the second cylinder 82 is activated according to the actual size of the glass, and through telescopic movement, it drives the third cylinder 83 at the top to adjust its vertical position, thereby changing the height of the correction positioning plate 84. Subsequently, the third cylinder 83 extends and retracts horizontally, pushing the correction positioning plate 84 closer to the side of the glass, and the groove 85 at the lower end of the inner side of the correction positioning plate 84... The positioning guide roller 86 contacts the side of the glass. Since the positioning guide roller 86 can rotate flexibly, its rolling contact during the glass conveying process can not only calibrate the lateral position of the glass, keeping the glass in a centered position on the conveying roller 4, but also avoid scratching the side of the glass due to hard compression. Through the coordinated operation of the second cylinder 82 and the third cylinder 83, the positioning device 8 can accurately adjust the position and height of the correction positioning plate 84, ensuring that glass of different specifications can maintain a stable and accurate position during the conveying and processing, providing a reliable positioning basis for subsequent cleaning and tempering treatment.

[0027] The operating principle and advantages of this invention are as follows: During the operation of this glass tempering furnace, the glass is first conveyed by the first conveyor frame 2. When the glass enters the first conveyor frame 2, the positioning device 8 starts operating. The side plate 81 is fixed at the four corners of the first conveyor frame 2. The second cylinder 82 on it can drive the third cylinder 83 to move vertically. The correction positioning plate 84 at the output end of the third cylinder 83 moves accordingly. The positioning guide roller 86 in the groove 85 at the lower inner side of the correction positioning plate 84 can rotate flexibly. When the glass is conveyed, the second cylinder 82 and the third cylinder 83 adjust the position and height of the correction positioning plate 84 according to the glass size. The positioning guide roller 86 contacts the side of the glass, and the glass is laterally calibrated and limited by rolling, ensuring that the glass is in a centered position on the conveyor roller 4, thus enabling the glass to move stably on the conveyor roller 4. Servo motors for driving the rotation of the conveyor roller 4 are provided on the sides of the first conveyor frame 2 and the second conveyor frame 3. At this time, the servo motors can drive the rotation of each conveyor roller 4. By driving the conveyor roller 4 to rotate, the glass can be moved vertically. The stable drive ensures stable conveying displacement of the tempered glass on each conveyor roller 4. Simultaneously, the drive motor 621, fixed to one end of the rail frame 61, rotates the lead screw 622 upon startup. The lead screw 622 is threadedly connected to the slider 623. Because the rail frame 61 has a U-shaped interior, it cooperates with the similarly U-shaped slider 623, restricting the slider 623 to linear motion only along the rail frame 61. When the slider 623 moves, it drives the side rod 631 and rack 632 to move. The spur gear 633 at the top outer end of the side rod 631 meshes with the rack 632, causing the straight... The rotation of gear 633 drives the rotation of bevel gear 634, which is fixedly connected to it. Bevel gear 634 meshes with bevel ring 645 on one side of cleaning ring 643, causing cleaning ring 643 to slide and rotate inside the annular rail 642. The cleaning brush 644 inside the cleaning ring 643 is in contact with the outer surface of the conveyor roller 4. When the cleaning ring 643 rotates, the cleaning brush 644 can wipe and clean dust, debris and other impurities on the surface of the conveyor roller 4. The wear-resistant pad on the outer surface of slider 623 can reduce friction with the rail frame 61 and extend service life.The outer ball bearing 646 of the cleaning ring 643 fits against the inner wall of the annular rail 642, reducing the resistance when the cleaning ring 643 slides and ensuring a smooth cleaning process. The coordinated design of the cleaning mechanism 64 and the transmission mechanism 63 enables the cleaning ring 643 to rotate while moving laterally on the outer surface of the conveyor roller 4, which can better brush and clean the outer surface of the conveyor roller 4. During use, the cleaning brush 644 on the inner side of the cleaning ring 643 can be replaced with a scraper as needed. The cleaning can be flexibly selected according to the requirements. While rotating, it can also move left and right on the outer surface of the conveyor roller 4, which can stably clean the outer surface of the conveyor roller 4 and avoid impurities on the outer surface of the conveyor roller 4 from affecting the glass. During use, when the glass moves onto the conveyor roller 4, the cleaning can be stopped. When the glass moves to the top of the conveyor roller 4, the roller cleaning device 6, which is not on top of the glass conveyor roller 4, can be activated for cleaning. This device can realize the functions of real-time conveying and real-time cleaning, which can maintain the stable conveying of the conveyor roller 4 while ensuring the cleanliness of the outer surface of the conveyor roller 4 and reducing the impact of impurities on the glass. During use, when the innermost roller cleaning device 6 is running, the tempered glass is not on top of the inner conveyor roller 4 of the roller cleaning device 6. At this time, the slider 623 can drive the connecting rod 71 to move. At this time, the connecting rod 71 fixed on the outside of the slider 623 closest to the tempering furnace body 5 will drive the concave frame 72 to move laterally. By driving the slider 623 to slide back and forth, the concave frame 72 can be driven to move back and forth. At this time, the first cylinder 732 in the upper and lower fixed seats 731 on the outside of the concave frame 72 is activated, pushing the substrate 733 and the glass cleaning scraper 734 to move and fit against the outer surface of the glass. Due to the limit on both sides of the glass positioning device 8, the glass cleaning scraper 734 is driven to move laterally back to the original position, thereby scraping and cleaning the impurities remaining on the upper and lower surfaces of the glass, ensuring the cleanliness of the glass surface. After cleaning and positioning, the glass then enters the tempering furnace body 5 for heating and rapid cooling, and is finally output through the second conveyor 3. Throughout the process, the various mechanisms work closely together to achieve effective cleaning of the glass and the conveyor roller 4 and precise positioning of the glass. During the application of this equipment, the roller cleaning device 6 drives the slider 623 through the lead screw 622, which in turn drives the cleaning ring 643 and cleaning brush 644 to rotate via gear transmission, achieving dynamic cleaning of the surface of the conveyor roller 4. The cleaning ring 643 rotates during its lateral movement, enabling more efficient cleaning. The roller cleaning device 6 can be activated to clean the tempered glass before it moves to or after it has moved from the outer surface of the conveyor roller 4. Compared with traditional manual cleaning, this equipment can clean continuously during operation, avoiding secondary contamination of the glass due to impurities on the surface of the conveyor roller 4, significantly reducing the amount of impurities remaining on the glass surface, and improving the surface quality and pass rate of the tempered glass products. The scraper design of the glass cleaning device 7 can specifically remove stubborn impurities on the glass surface, making up for the lack of pre-treatment cleaning in traditional tempering furnaces, ensuring that the glass surface entering the tempering furnace is clean. At the same time, during application, the positioning device 8, through the linkage of the second cylinder 82 and the third cylinder 83, can flexibly adjust the position and height of the correction positioning plate 84 according to different sizes of glass. The positioning guide roller 86 uses a rolling contact method. This system can accurately calibrate the glass position while avoiding scratches on the glass sides, ensuring the positional accuracy of the glass during conveying and processing, and reducing dimensional errors and quality defects in tempered glass caused by positional deviations. During use, the convex-shaped cooperation structure between the slider 623 and the rail frame 61 in the roller cleaning device 6 effectively restricts the movement direction of the slider 623 and prevents deviation. The setting of wear-resistant pads and balls 646 reduces frictional wear between components, extends the service life of the equipment, and reduces maintenance frequency and costs. The glass cleaning device 7 adopts a second cylinder 82 and a third cylinder 83 drive structure, which can adjust the scraper position according to the glass thickness, adapting to the cleaning needs of different specifications of glass and enhancing the versatility of the equipment. All devices in this glass tempering furnace are linked by the control system. From glass positioning and conveying roller 4 cleaning to glass surface cleaning, no excessive manual intervention is required, enabling automated continuous production. Compared with the traditional method of relying on manual periodic shutdowns for cleaning, this significantly improves production efficiency, reduces labor costs, and ensures the stability of cleaning and positioning effects, meeting the needs of modern glass deep processing for efficient and high-quality production.
