Description

Technical Field

[0001] The utility model relates to the technical field of cooling assembly lines, in particular to a cooling and temperature-reducing assembly line for glass tempering. Background Art

[0002] The cooling and temperature-reducing assembly line for glass tempering is a special continuous cooling equipment supporting the glass tempering production process, whose core definition is a key production assembly line that rapidly and uniformly cools the glass plates just discharged from the tempering furnace at high temperature to normal temperature through a preset conveying system and airflow regulating device, so as to form a uniformly distributed stress structure inside the glass and finally obtain tempered glass with high strength and high safety.

[0003] In the current cooling and temperature-reducing assembly lines for glass tempering, air cooling is the mainstream cooling technology, and its cooling effect is closely related to the matching precision of the air outlet frame and the air return hood. Since glass plates of different specifications and thicknesses have different requirements for cooling speed and airflow distribution, it is often necessary to adjust the spacing between the air outlet frames in the production process to adapt to different production process parameters. However, the air return hoods of the existing assembly lines generally adopt a stamping integral molding design, with a fixed width, which is not convenient to adjust according to the spacing between adjacent air outlet frames, thus affecting the air guiding effect. Contents of the Utility Model

[0004] The purpose of the utility model is to at least solve one of the technical defects mentioned above.

[0005] To this end, one purpose of the utility model is to propose a cooling and temperature-reducing assembly line for glass tempering, so as to solve the problems mentioned in the background art and overcome the deficiencies existing in the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a cooling and heat dissipation production line for glass tempering, comprising a frame, wherein a liftable assembly frame is disposed inside the frame, and a plurality of linearly arrayed first air guide frames are fixedly connected to the top of the assembly frame, and a connecting frame is disposed between every two adjacent first air guide frames, the tops of the plurality of connecting frames are all connected to the assembly frame by bolts, two symmetrically arranged air guide plates are slidably connected inside the assembly frame, and two threaded sleeves that are slidably connected to the top of each air guide plate are fixedly connected to the top of each air guide plate, and a locking bolt is threaded inside each threaded sleeve, the bottom surfaces of the plurality of locking bolts are all in contact with the top surface of the connecting frame, two side plates are fixedly connected inside the frame, and a plurality of linearly arrayed conveying rollers are rotatably connected between the two side plates by bearings, the plurality of conveying rollers and the plurality of first air guide frames are staggered, and a plurality of linearly arrayed second air guide frames are fixedly connected between the two side plates, the plurality of first air guide frames and the plurality of second air guide frames are vertically corresponding, and the first air guide frames and the second air guide frames are all connected to the output end of a fan through pipes.

[0007] Preferably, in any of the above embodiments, the top of the frame is rotatably connected to a plurality of symmetrically arranged first sprockets via bearings, the top of the assembly frame is fixedly mounted with two motors, each motor has a winding reel fixedly connected to its drive shaft, each winding reel is fixedly connected to the frame with two chains, and the top of the assembly frame is rotatably connected to a plurality of symmetrically arranged third sprockets via bearings, wherein the first sprockets and the third sprockets are engaged with the chains.

[0008] Preferably, in any of the above embodiments, a plurality of linearly arrayed raised rings are fixedly connected to the outer surface of the conveying roller shaft, and the center of the raised rings coincides with the axis of the conveying roller shaft.

[0009] Preferably, in any of the above solutions, the top of the connecting frame has a plurality of symmetrically arranged slots, and the threaded sleeve is slidably connected to the connecting frame through the slots.

[0010] Preferably, in any of the above solutions, the first air guide frame has an embedding groove on both the left and right sides, and the end of the air guide plate away from the connecting frame is in contact with the inner wall of the embedding groove.

[0011] Preferably, in any of the above solutions, limit plates are fixedly connected to both the upper and lower sides of the air guide plate, and the inner wall of the connecting frame is provided with a limit groove that matches the limit plate.

[0012] Preferably, of any of the above solutions, a U-shaped frame is fixedly connected to the top of the connecting frame, and the U-shaped frame is fixedly installed inside the assembly frame by bolts.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. The design allows for flexible adjustment of the air guide frame spacing to meet diverse glass cooling needs. When adjusting the spacing of the first air guide frame according to glass specifications, first loosen the locking bolts in the threaded sleeve, then push the air guide plate along the groove of the connecting frame. The limiting plates on both sides of the air guide plate move along the limiting grooves to ensure smooth sliding. Simultaneously, the end of the air guide plate away from the connecting frame slides in close contact with the embedded groove of the first air guide frame. After adjusting to the target spacing, retighten the locking bolts to press the bottom surface of the air guide plate firmly against the top of the connecting frame, thereby adjusting the width of the air guide structure. It can be installed between air outlet frames with different spacings and adjusted according to the actual spacing between adjacent air outlet frames. The motor drives the winding reel to rotate, which in turn drives the first and third sprockets via a chain to raise and lower the assembly frame, adjusting the vertical distance between the first and second air guide frames. This design breaks the limitations of traditional fixed structures, flexibly adapting to the cooling parameters of different glasses, ensuring uniform airflow distribution, and improving cooling effect and product qualification rate.

[0015] 2. Improve cooling uniformity and conveying stability to ensure production efficiency. After the glass enters the production line, the raised ring on the outer surface of the conveyor roller increases the contact points with the glass, preventing the glass from denting due to its own weight and reducing surface friction to prevent scratches. The fan delivers air to the first and second air guide frames through pipes, forming a counter-flowing airflow that rapidly cools the glass. The U-shaped frame securely fixes the connecting frame within the assembly frame, preventing the connecting frame from shifting due to airflow impact. The air guide plate fits snugly with the embedded groove to form a closed airflow channel, preventing airflow leakage and ensuring that the cooling air is concentrated on the glass surface. When glass specifications change, there is no need to stop the machine to replace the air guide frame components. Parameter adaptation can be completed by adjusting the air guide plate and raising / lowering the assembly frame. Combined with the stable conveying of the conveyor roller, this ensures the continuity of the cooling process, reduces equipment debugging time, and improves production efficiency and cooling quality.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited thereto.

[0025] like Figures 1 to 7 As shown, a cooling production line for glass tempering includes a frame 1. Inside the frame 1 is a liftable assembly frame 2. Several linearly arrayed first air guide frames 3 are fixedly connected to the top of the assembly frame 2. A connecting frame 4 is provided between every two adjacent first air guide frames 3. The tops of the connecting frames 4 are all bolted to the assembly frame 2. Two symmetrically arranged air guide plates 5 are slidably connected inside the assembly frame 2. The top of each air guide plate 5 is fixedly connected to two threaded sleeves 6 that are slidably connected to the connecting frames 4. The internal threads of each threaded sleeve 6 are connected... A locking bolt 20 is connected, and the bottom surfaces of several locking bolts 20 are all in contact with the top surface of the connecting frame 4. Two side plates 7 are fixedly connected inside the frame 1. Several linear array conveying rollers 8 are rotatably connected between the two side plates 7 through bearings. Several conveying rollers 8 are staggered with several first air guide frames 3. Several linear array second air guide frames 9 are fixedly connected between the two side plates 7. Several first air guide frames 3 and several second air guide frames 9 correspond vertically. Both the first air guide frames 3 and the second air guide frames 9 are connected to the output end of the fan through pipes.

[0026] As an optional technical solution of this utility model, the top of the frame 1 is rotatably connected to several symmetrically arranged first sprockets 10 via bearings. The top of the assembly frame 2 is fixedly installed with two motors 11. The drive shaft end of each motor 11 is fixedly connected to a winding reel 12. Each winding reel 12 is fixedly connected to the frame 1 with two chains 13. The top of the assembly frame 2 is rotatably connected to several symmetrically arranged third sprockets 14 via bearings. The first sprockets 10 and the third sprockets 14 are both meshed with the chains 13. The winding reel 12 is driven to rotate by the motor 11. The chain 13 is meshed with the first sprockets 10 and the third sprockets 14 for transmission. The drive shaft end of the motor (11) is fixedly connected to a second sprocket (12). When the second sprocket (12) rotates, it winds up the chain (13). The lifting function of the frame 1 is realized by changing the length of the chain (13). This sprocket and chain drive structure provides a balanced and reliable driving force, ensuring smooth and tilt-free lifting of the assembly frame 2. It precisely adjusts the distance between the first air guide frame 3 and the second air guide frame 9 on the assembly frame 2, allowing for flexible adaptation to the cooling requirements of glass of different thicknesses and specifications. This avoids uneven cooling caused by a fixed spacing between the air guide frames, providing a suitable cooling environment for the glass and ensuring tempering quality. Simultaneously, the symmetrically arranged transmission components ensure balanced force on the assembly frame 2, reducing swaying during lifting, extending equipment lifespan, and improving the stability of the production line operation.

[0027] As an optional technical solution of this utility model, a number of linear array of raised rings 15 are fixedly connected to the outer surface of the conveying roller shaft 8. The center of the raised rings 15 coincides with the axis of the conveying roller shaft 8. The raised rings 15 on the outer surface of the conveying roller shaft 8 are evenly distributed with the axis as the center. This not only increases the contact support points with the glass to prevent the glass from sinking under its own weight, but also reduces the contact area to reduce the risk of friction and scratches, thus ensuring the flatness and surface quality of the glass during conveying.

[0028] As an optional technical solution of this utility model, the top of the connecting frame 4 is provided with a number of symmetrically arranged slots 16. The threaded sleeve 6 is slidably connected to the connecting frame 4 through the slots 16. The slots 16 at the top of the connecting frame 4 provide a precise sliding path for the threaded sleeve 6, ensuring that the threaded sleeve 6 drives the air guide plate 5 to move smoothly without deviation. At the same time, it limits the threaded sleeve 6 to avoid over-adjustment and improves the accuracy of the air guide frame spacing adjustment.

[0029] As an optional technical solution of this utility model, the first air guide frame 3 has an embedding groove 17 on both the left and right sides. The end of the air guide plate 5 away from the connecting frame 4 is attached to the inner wall of the embedding groove 17. The embedding groove 17 of the first air guide frame 3 is tightly attached to the end of the air guide plate 5 to form a closed airflow channel to prevent the cooling air from leaking out, ensuring that the cooling air is concentrated on the glass surface, improving the cooling efficiency and uniformity while enhancing the installation stability of the air guide plate 5.

[0030] As an optional technical solution of this utility model, the upper and lower sides of the air guide plate 5 are fixedly connected with limit plates 18, and the inner wall of the connecting frame 4 is provided with a limit groove 19 that is adapted to the limit plate 18. The limit plate 18 of the air guide plate 5 and the limit groove 19 of the connecting frame 4 slide together to form an upper and lower limit on the air guide plate 5, preventing deviation and shaking during adjustment, ensuring that the air guide plate 5 is always horizontal, and ensuring stable airflow guidance and consistent cooling effect.

[0031] As an optional technical solution of this utility model, a U-shaped frame 21 is fixedly connected to the top of the connecting frame 4. The U-shaped frame 21 is fixedly installed inside the assembly frame 2 by bolts. The U-shaped frame 21 at the top of the connecting frame 4 is firmly fixed inside the assembly frame 2, which enhances the installation firmness of the connecting frame 4, avoids displacement caused by airflow impact or equipment vibration, and provides a reliable structural foundation for uniform delivery of cooling air.

[0032] A cooling and temperature reduction production line for glass tempering operates on the following principle:

[0033] 1) To achieve flexible adjustment of the air guide frame spacing and adapt to various glass cooling needs. When it is necessary to adjust the spacing of the first air guide frame 3 according to the glass specifications, first loosen the locking bolt 20 inside the threaded sleeve 6.

[0034] 2): Push the air guide plate 5 to slide along the slot 16 of the connecting frame 4. The limiting plates 18 on both sides of the air guide plate 5 move along the limiting slot 19 to ensure smooth sliding. At the same time, the end of the air guide plate 5 away from the connecting frame 4 slides in the embedded slot 17 of the first air guide frame 3.

[0035] 3): After adjusting to the target spacing, tighten the locking bolts 20 again to press the bottom surface of the connecting frame 4 against the top fixed air guide plate 5. This allows for adjustment of the width of the air guide structure and can be installed between air outlet frames with different spacings.

[0036] In summary, this glass tempering cooling production line allows for flexible adjustment of the air guide frame spacing, adapting to diverse glass cooling needs. When adjusting the spacing of the first air guide frame 3 according to glass specifications, first loosen the locking bolt 20 inside the threaded sleeve 6, pushing the air guide plate 5 to slide along the groove 16 of the connecting frame 4. The limiting plates 18 on both sides of the air guide plate 5 move along the limiting groove 19 to ensure smooth sliding. At the same time, the end of the air guide plate 5 away from the connecting frame 4 slides against the embedded groove 17 of the first air guide frame 3. After adjusting to the target spacing, retighten the locking bolt 20 so that its bottom surface presses against the top of the connecting frame 4 to fix the air guide plate 5. This allows for adjustment of the air guide structure width and can be installed between air outlet frames with different spacings. The motor 11 drives the winding reel 12 to rotate, which in turn drives the first sprocket 10 and the third sprocket 14 to rotate via the chain 13, thereby raising and lowering the assembly frame 2 and adjusting the vertical distance between the first air guide frame 3 and the second air guide frame 9. This design breaks away from the limitations of traditional fixed structures, flexibly adapting to the cooling parameters of different glasses, ensuring uniform airflow distribution, and improving cooling effect and product qualification rate. It enhances cooling uniformity and conveying stability, ensuring production efficiency. After the glass enters the production line, the raised ring 15 on the outer surface of the conveyor roller 8 increases the contact points with the glass, preventing the glass from denting due to its own weight and reducing surface friction to prevent scratches. The fan delivers air to the first air guide frame 3 and the second air guide frame 9 through pipes, forming a counter-flowing airflow that rapidly cools the glass. The U-shaped frame 21 securely fixes the connecting frame 4 within the assembly frame 2, preventing the connecting frame 4 from shifting due to airflow impact. The air guide plate 5 and the embedded groove 17 form a closed airflow channel, preventing airflow leakage and ensuring that the cooling air is concentrated on the glass surface. When glass specifications change, there is no need to stop the machine to replace the air guide frame components; parameter adaptation can be achieved by adjusting the air guide plate 5 and raising / lowering the assembly frame 2. Combined with the stable conveying of the conveyor roller 8, this ensures the continuity of the cooling process, reduces equipment debugging time, and improves production efficiency and cooling quality.
