Description

Technical Field

[0001] This invention relates to the field of tempering furnace technology, and more particularly to a glass tempering furnace and its method of use. Background Technology

[0002] A glass tempering furnace is a specialized piece of equipment used for heating and tempering glass. Its basic principle is to heat the glass to near its softening point, then rapidly and uniformly cool it, forming a compressive stress layer on the glass surface, thereby improving the glass's mechanical strength and resistance to thermal shock. A complete glass tempering production line typically includes main processes such as glass cleaning and drying, heating and tempering, and rapid cooling.

[0003] In the glass tempering process, the glass substrate needs to be smoothly transported between different stages using a conveyor system. Existing conveyor systems often employ a roller conveyor structure, using a series of parallel conveyor rollers to move the glass. However, in actual production, it has been found that due to the lack of effective lateral restraint on the conveyor rollers, especially when the glass size is much smaller than the width of the conveyor rollers, the glass is prone to deviation. Once the glass deviates, it can lead to uneven heating after entering the tempering furnace, affecting the tempering quality; in severe cases, it may collide with the furnace sidewalls or cause broken glass to become stuck, resulting in equipment failure or even a production accident.

[0004] To address the issue of glass misalignment, some existing technologies incorporate fixed guide strips or limiting wheels on the conveyor system. For example, fixed baffles are installed on both sides of the conveyor rollers to limit the maximum deviation of the glass. However, these fixed limiting structures have significant drawbacks: their limiting width is fixed and cannot be flexibly adjusted according to the actual width of the glass being processed. When producing glass of different specifications, especially different widths, fixed limiting devices may not effectively constrain small-sized glass, and excessive gaps can still lead to misalignment; while for large-sized glass, insufficient gaps may cause severe friction or even jamming between the glass edge and the limiting device, damaging the glass edge or affecting the smoothness of the conveying process. Therefore, operators need to manually adjust the position of the limiting components according to the glass batch, which is cumbersome, inefficient, and difficult to guarantee in terms of adjustment accuracy. Therefore, a glass tempering furnace and its operating method are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a glass tempering furnace and its usage method, thereby solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A glass tempering furnace includes a conveying device, a spraying device, a drying device, a tempering furnace body, and a cooling device. The spraying device, drying device, tempering furnace body, and cooling device are arranged sequentially on the conveying device from right to left. Observation windows are respectively provided on one side of the spraying device, drying device, tempering furnace body, and cooling device. A water storage tank and a wastewater tank are respectively provided below the conveying device. The water storage tank is connected to the spraying device, and the wastewater tank is located below the spraying device. A limit device is provided on the conveying device.

[0007] Furthermore, the transmission device includes a support frame, a drive roller, several driven rollers, a transmission chain, and a transmission motor. The drive roller is rotatably mounted on one end of the support frame, with one end extending out of the support frame. A gear is mounted on one end of the drive roller, and one end of the drive roller is connected to the output end of the transmission motor. The several driven rollers are equidistantly arranged along the length of the support frame and are rotatably mounted on the support frame. One end of each driven roller extends out of the support frame, and a gear is mounted on one end of each driven roller. The transmission chain is wound around the gear.

[0008] Furthermore, limit blocks are respectively provided at both ends between the two driven rollers, and a limit rod is provided at the middle of the top of the limit block, with a limit sleeve fitted on the limit rod.

[0009] Furthermore, the limiting device includes a limiting motor, several positive and negative threaded rods, and several smooth rods. The positive and negative threaded rods are rotatably mounted on a support frame, with one end of each rod extending out of the support frame. A limiting gear is provided at one end of each threaded rod, and a limiting chain is wound around the limiting gear. The output end of the limiting motor is connected to one end of each threaded rod. Limiting blocks are threadedly connected to both ends of the threaded rods. Two smooth rods are slidably connected to both ends of the two limiting blocks, and the smooth rods are respectively located on both sides of the threaded rods.

[0010] Furthermore, the spraying device includes a water pump, a water suction pipe, several nozzles, and a spraying support frame. The spraying support frame is located at the right end of the transmission device. The water pump is located on one side of the water storage tank. One end of the water pump is connected to the water storage tank, and the other end of the water pump is connected to the water suction pipe passing through the spraying support frame. The water suction pipe is connected to the top of the spraying support frame. A fixed water pipe is provided on the top of the inner side of the spraying support frame. The fixed water pipe is connected to the water suction pipe. The several nozzles are spaced apart on the fixed water pipe, and the nozzles are connected to the fixed water pipe.

[0011] Furthermore, the drying device includes a drying support and several drying fans. The drying support is mounted on the transmission device, and an air outlet is provided on the top of the drying support. A connecting rod is provided on the inner side of the drying support, and the several drying fans are respectively mounted on the connecting rod. Furthermore, the cooling device includes a cooling bracket, several air coolers and an exhaust fan. The cooling bracket is located at the left end of the transmission device, the several air coolers are respectively located on the two side walls of the cooling bracket, and the exhaust fan is located at the top of the cooling bracket. The air inlet of the exhaust fan is connected to the interior of the cooling bracket.

[0012] A method of using a glass tempering furnace includes the following steps: S1: Adjusting the limiting device: Start the limiting motor to drive the positive and negative threaded rods to rotate. The positive and negative threaded rods drive the limiting blocks at both ends to move in opposite directions along the smooth rod, so that the distance between the limiting sleeves on the two limiting blocks is equal to the width of the glass to be tempered. S2: Loading and Spray Cleaning: Place the glass to be tempered on the right end of the conveyor and start the conveyor motor. The conveyor motor drives the glass to be tempered from left to right. The glass first enters the spray device and is sprayed onto the upper and lower surfaces of the glass through the nozzles for cleaning. The wastewater after cleaning falls into the wastewater tank below. S3: Drying process: The cleaned tempered glass is transferred to the drying device via the conveyor. The drying fan blows out hot air to dry the glass surface. S4: Tempering Heating: The dried glass to be tempered enters the tempering furnace body and is heated according to the preset tempering temperature and time; S5: Cooling and Shaping: After heating, the glass enters the cooling device. The cold air blower blows cold air onto the glass for rapid cooling, while the exhaust fan extracts the hot air from inside the cooling bracket to complete the tempering process. The present invention, by adopting the above-described technical solution, has the following beneficial effects: This invention, by setting an adjustable limiting device on the transmission device, uses a positive and negative threaded rod and a limiting motor to drive the limiting blocks on both sides to move synchronously in opposite directions. It can accurately adjust the distance between the two limiting sleeves according to the actual width of the glass to be tempered. This not only effectively prevents the glass from deviating due to vibration, roller skew, etc. during transmission, but also can quickly adapt to the production needs of glass of different widths, avoiding the tediousness and errors of manual adjustment, and greatly improving production efficiency and equipment flexibility.

[0013] The method provided by this invention first adjusts the limiting device to match the width of the glass, and then sequentially performs feeding, spray cleaning, drying, tempering heating and cooling molding. The steps are logically clear. Since the limiting adjustment can be completed quickly before production, and the glass is continuously guided throughout the entire transmission process, no manual intervention is required, which significantly reduces the difficulty of operation.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0017] like Figure 1-3As shown, a glass tempering furnace includes a conveying device 1, a spraying device 2, a drying device 3, a tempering furnace body 4, and a cooling device 5. The spraying device 2, drying device 3, tempering furnace body 4, and cooling device 5 are arranged sequentially on the conveying device 1 from right to left. Each of the spraying device 2, drying device 3, tempering furnace body 4, and cooling device 5 has an observation window 9 on one side for observing the internal operating status. The observation window 9 can be made of high-temperature resistant tempered glass and equipped with LED lighting for convenient observation at night or in low light conditions. A water storage tank 6 and a wastewater tank 7 are respectively arranged below the conveying device 1. The water storage tank 6 is connected to the spraying device 2 and is used to provide cleaning water. The wastewater tank 7 is located below the spraying device 2 and is used to collect wastewater after spraying. A limit device 8 is provided on the conveying device 1 to prevent the glass from deviating.

[0018] like Figure 2 As shown, the transmission device 1 includes a support frame 11, a drive roller 12, several driven rollers 13, a transmission chain 14, and a transmission motor 15. The drive roller 12 is rotatably mounted at one end of the support frame 11, with one end extending out of the support frame 11. A gear is mounted on one end of the drive roller 12, and this end is connected to the output end of the transmission motor 15. The several driven rollers 13 are equidistantly arranged along the length of the support frame 11, and are rotatably mounted on the support frame 11. One end of each driven roller 13 extends out of the support frame 11, and a gear is mounted on one end of each driven roller. The transmission chain 14 is wound around the gear. When the transmission motor 15 starts, it drives the drive roller 12 to rotate, which in turn drives all the driven rollers 13 to rotate synchronously and in the same direction via the transmission chain 14, thereby achieving stable glass transmission.

[0019] In an embodiment of the present invention, limit blocks 16 are respectively provided at both ends between the two driven rollers 13, and a limit rod 17 is provided at the middle of the top of the limit block 16. A limit sleeve 18 is fitted on the limit rod 17. The limit sleeve 18 is made of wear-resistant rubber or polyurethane material, and its outer surface is smooth, which can reduce friction damage when the glass edge comes into contact with it.

[0020] Preferably, a rolling bearing can be provided between the limiting sleeve 18 and the limiting rod 17, so that the limiting sleeve 18 can rotate freely. When the glass edge contacts it, the sliding friction is changed to rolling friction, which further reduces the damage to the glass.

[0021] like Figure 3As shown, the limiting device 8 includes a limiting motor 81, several positive and negative threaded rods 82, and several smooth rods 83. The positive and negative threaded rods 82 are rotatably mounted on the support frame 11, and one end of the positive and negative threaded rods 82 extends out of the support frame 11. A limiting gear 84 is provided at one end of the positive and negative threaded rods 82, and a limiting chain 87 is wound around the limiting gear 84. The output end of the limiting motor 81 is connected to one end of the positive and negative threaded rods 82. The limiting blocks 83 are respectively threaded to both ends of the positive and negative threaded rods 82. The two smooth rods 83 are respectively slidably connected to both ends of the two limiting blocks 16, and the smooth rods 83 are respectively arranged on both sides of the positive and negative threaded rods 82. The threaded rod 82 has two sections of threads with opposite directions, located at both ends of the rod body. The middle of each limiting block 16 is threadedly connected to the threaded rod 82, and both ends of the limiting block 16 are slidably connected to two smooth rods 83. The two ends of the smooth rods 83 are connected to the support frame 11, and the smooth rods 83 are arranged parallel to both sides of the threaded rod 82, serving a guiding function. When the limiting motor is started, it drives one threaded rod 82, and the other threaded rods 82 rotate synchronously. Due to the action of the threads, the limiting blocks 16 at both ends of the same threaded rod 82 will move towards each other (the distance between them decreases) or move in opposite directions (the distance between them increases), thereby precisely adjusting the horizontal distance between the left and right limiting sleeves 18 to accommodate glass of different widths.

[0022] like Figure 4 As shown, the spraying device 2 includes a water pump 21, a water suction pipe 22, several nozzles 23, and a spraying support frame 24. The spraying support frame 24 is located at the right end of the transmission device 1. The water pump 21 is located on one side of the water storage tank 6. One end of the water pump 21 is connected to the water storage tank 6, and the other end of the water pump 21 is connected to the water suction pipe 22 passing through the spraying support frame 24. The other end of the water pump 21 is connected to the water suction pipe 22. The water suction pipe 22 is connected to the top of the spraying support frame 24. A fixed water pipe is provided on the top of the inner side of the spraying support frame 24. The fixed water pipe is connected to the water suction pipe 22. The several nozzles 23 are spaced apart on the fixed water pipe and are connected to the fixed water pipe. Multiple nozzles 23 are spaced apart along the glass conveying direction on the fixed water pipe, with the nozzle outlets facing the upper surface of the glass. To further clean the lower surface of the glass, a set of nozzles (not shown in the figure) can also be installed below the conveying roller at the spray support frame 24, arranged opposite to the upper nozzles. The wastewater after cleaning falls directly into the wastewater tank 7 below, which has a drain outlet at the bottom for easy periodic cleaning.

[0023] Preferably, a heater can be installed in the water storage tank 6 of the spray device 2 to preheat the cleaning water in winter or when the water temperature is low, thereby improving the cleaning effect.

[0024] like Figure 5As shown, the drying device 3 includes a drying support 31 and several drying fans 32. The drying support 31 is mounted on the conveying device 1, and an air outlet 33 is provided at the top of the drying support 31. A connecting rod 34 is provided on the inner side of the drying support 31. The several drying fans 32 are respectively mounted on the connecting rod 34, and the air outlet direction of the fans is towards the glass surface. The drying fans 32 are electric heating fans, which blow hot air to quickly dry the cleaned glass. like Figure 6 As shown, the cooling device 5 includes a cooling bracket 51, several air coolers 52, and an exhaust fan 53. The cooling bracket 51 is located at the left end of the transmission device 1. The several air coolers 52 are respectively installed on the two side walls of the cooling bracket 51. The exhaust fan 53 is located on the top of the cooling bracket 51, and its air inlet is connected to the interior of the cooling bracket 51. The several air coolers 52 are symmetrically installed on the two side walls of the cooling bracket 51, with their air outlets facing the upper and lower surfaces of the glass. Multi-angle airflow can be achieved through the nozzle design. The exhaust fan 53 is installed on the top of the cooling bracket 51, and its air inlet is connected to the interior of the cooling bracket 51. It is used to promptly remove the hot air generated during the cooling process, maintain cold air circulation, and improve cooling efficiency.

[0025] Preferably, the outlet of the exhaust fan 53 of the cooling device 5 can be connected to the factory exhaust system to prevent hot air from being directly discharged into the workshop and affecting the working environment.

[0026] A method of using a glass tempering furnace includes the following steps: S1: Adjusting the limiting device: Start the limiting motor 81 to drive the positive and negative threaded rod 82 to rotate. The positive and negative threaded rod 82 drives the limiting blocks 16 at both ends to move towards or away from each other along the smooth rod, so that the distance between the limiting sleeves 18 on the two limiting blocks 16 is equal to the width of the glass to be tempered. If it is necessary to reduce the distance, control the rotation direction of the limiting motor 81 to move the two limiting blocks 16 towards each other. If it is necessary to increase the distance, rotate in the opposite direction to move the two limiting blocks in the opposite direction until the net distance between the two limiting sleeves 18 is equal to the width of the glass to be tempered (a small gap of 1~3mm can be reserved to ensure smooth passage). After adjustment, turn off the limiting motor 81. The positive and negative threaded rod 82 has a self-locking function and can maintain its position.

[0027] S2: Loading and Spray Cleaning: Place the glass to be tempered on the right end of the conveyor 1, start the conveyor motor 15, and the conveyor motor 15 drives the glass to be tempered from left to right. The glass first enters the spray device 2, and is sprayed and cleaned on the upper and lower surfaces of the glass through the nozzle 23. The wastewater after cleaning falls into the wastewater tank 7 below. When the glass first enters the spray device 2, the water pump 21 is started. The water pump 21 draws clean water from the water storage tank 6 and delivers it to the nozzle 23 through the water pumping pipe 22. The nozzle 23 sprays high-pressure water jets onto the upper and lower surfaces of the glass to remove dust, oil and other impurities from the glass surface. The wastewater after cleaning falls into the wastewater tank 7 below under the action of gravity and is collected to prevent it from flowing to the subsequent process.

[0028] S3: Drying process: The cleaned glass to be tempered enters the drying device 3 along with the conveyor 1. The drying fan 32 blows out hot air to dry the glass surface. The drying fan 32 is started and blows out hot air to quickly dry the glass surface. At the same time, the humid air is discharged from the air outlet 33 at the top of the drying bracket 31. After drying, there are no water stains left on the surface of the glass, which meets the requirements for tempering and entering the furnace.

[0029] S4: Tempering Heating: The dried glass to be tempered enters the tempering furnace body 4 and is heated according to the preset tempering temperature and time. The tempering furnace body 4 is equipped with heating elements (such as electric heating wires or quartz heating tubes), which heat the glass according to the preset tempering process parameters (e.g., heating temperature 680~720℃, heating time set according to the glass thickness, usually 30~60 seconds / mm thickness) to make the glass soften uniformly. During the heating process, because the limiting sleeves 18 on both sides always guide the edge of the glass, the glass will not deviate and ensure that it is located in the central area of ​​the tempering furnace and is heated evenly.

[0030] S5: Cooling and Forming: After heating, the glass enters the cooling device 5. The cold air blower 52 blows cold air onto the glass for rapid cooling, while the exhaust fan 53 extracts the hot air from inside the cooling bracket 51, completing the tempering process. The cold air blower 52 and the exhaust fan 53 are started. The cold air blower 52 blows room temperature or cooled compressed air onto the upper and lower surfaces of the glass, causing the glass surface to cool rapidly and forming a tempered compressive stress layer. At the same time, the exhaust fan 53 continuously extracts the hot air accumulated inside the cooling bracket 51 to prevent hot air from stagnating and affecting the cooling rate. After cooling is completed, the glass is output from the left end of the transmission device 1, thus obtaining the tempered finished product.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
