Description

Technical Field

[0001] This invention relates to the field of special tempered glass manufacturing technology, specifically to a furnace unloading device for tempered glass manufacturing. Background Technology

[0002] Tempered glass is widely used due to its high strength, resistance to breakage, and the fact that even if it breaks, it produces almost no sharp-edged particles. Currently, tempered glass is usually manufactured using physical tempering methods. The basic principle is to heat ordinary glass to its softening temperature and then rapidly cool it, causing compressive stress to form on the surface of the cooled glass and tensile stress to form inside the glass, thus turning ordinary annealed glass into tempered glass. The "furnace exit device" for tempered glass is usually not a separate piece of equipment, but refers to the exit end of the tempering furnace, or auxiliary equipment that connects to it to complete the sheet taking, transfer, and cooling.

[0003] Existing tempered glass unloading devices typically consist of two parts: a conveyor roller conveyor and a cooling air grid. The conveyor roller conveyor is responsible for drawing the high-temperature glass out of the heating furnace, while the cooling air grid rapidly cools the glass by blowing cold air. However, during the rapid cooling tempering process, the glass surface is prone to localized micro-bulges or warping deformation due to uneven temperature distribution or raw material defects. Traditional cooling devices use a fixed airflow, which cannot be adjusted in real time according to the actual deformation of the glass surface. This results in insufficient cooling of the protruding areas, exacerbated deformation, severely affecting the flatness of the glass, and even causing defective products. Summary of the Invention

[0015] This invention provides a furnace-unloading device for tempered glass manufacturing, which has the following beneficial effects: During use, the glass exiting the furnace can be rapidly cooled and then slowly cooled sequentially during the conveying process, thereby ensuring successful tempering and smooth unloading. During rapid cooling, the air volume can be adjusted according to the slight deformation of the glass surface to ensure the flatness of the glass. During slow cooling, the glass can be flexibly positioned to prevent it from shifting or being damaged by impact, ensuring smooth unloading. The device also completes the reciprocating oscillation of the glass during the slow cooling process. If the glass breaks during furnace-unloading, it can be automatically handled to prevent the shards from splashing, ensuring the cleanliness of the device and preventing shards from getting stuck in the device and causing malfunctions.

[0016] 1. In the glass conveying process of this invention, a fan can send cold air into the air hood, and then rapidly cool and slowly cool the glass exiting the furnace through the rapid cooling air inlet and the slow cooling air inlet, thereby ensuring successful tempering of the glass and smooth removal of parts. During the rapid cooling process, the soft pressure roller can adhere to the glass surface under the action of the soft pressure spring. When there is a protrusion on the glass and the protrusion passes under the soft pressure roller, the soft pressure roller can cooperate with the conveying roller to perform initial leveling of the glass. At the same time, due to the deformation of the glass, it will drive the slide to move in the slide rail, drive the stop plate to squeeze the liquid in the hydraulic chamber into the control groove through the connecting channel, drive the control plate to move in the control groove and the rapid cooling air inlet, increase the opening of the rapid cooling air inlet, increase the cooling air volume received by the glass protrusion, suppress the protrusion, and prevent the deformation from developing. After passing the protrusion, the control plate returns to its original position, thereby restoring the air volume to normal, avoiding the glass from shrinking due to overcooling and causing dents, thus ensuring that the glass can be successfully tempered and maintain its surface flatness.

[0017] 2. In this invention, after the glass enters the slow cooling section, cold air, guided by the grid plate, slowly cools the glass through the slow cooling vents. When the glass edge contacts the positioning plate, the adhesive plate provides initial cushioning, preventing the glass from directly impacting the positioning plate and causing breakage. Simultaneously, the positioning plate slides within the sliding frame due to the pressure from the glass, compressing the buffer spring for secondary cushioning. As the positioning plate moves, it squeezes the liquid within the sliding frame into the bottom frame. Simultaneously, the limiting rod drives the gear rack to move within the transmission groove, and the grid plate rotates within the slow cooling vents, adjusting the airflow direction to achieve the effect of wind following the object's movement, realizing dynamic matching of wind direction with glass displacement. As liquid is injected into the bottom frame, the friction strip is lifted by the liquid and comes into contact with the glass, slowing down the glass and pushing it away from the conveyor roller. After the glass stops moving, it will apply pressure to the friction strip under the action of gravity. At the same time, the positioning plate slowly rebounds, causing the glass to move back a certain distance. The toothed rod drives the grid plate to rotate in the slow cooling air vent, causing the airflow to return to the original direction as the glass moves back. The glass descends with the friction strip until it contacts the conveyor roller, where it will be moved again by the conveyor roller and squeeze the positioning plate. This process is repeated, causing the glass to swing back and forth on the right side of the frame for cooling, until the glass drops to the predetermined temperature and is then removed.

[0018] 3. In use, the motor drives the conveyor rollers to transport the glass exiting the furnace. When the glass breaks, the fragments fall onto the guide plate. Upon sensing a pressure change, the pressure sensor immediately activates the telescopic rod, which, via a slider, moves the leftmost conveyor roller, clearing the space above the left guide plate. The broken glass slides along the guide plate into the crushing chamber. During the movement of the slider, the conveyor rollers stop rotating. When the slider reaches the rightmost end of the chute, the drive gear engages with the synchronous gear, allowing the conveyor rollers to rotate the crushing shaft. At this point, the belt tightens again, and the motor drives the conveyor rollers to rotate again. The tension between the conveyor rollers... The tensioning wheel structure rotates synchronously. When the slider moves, it can drive the top plate and the air control plate to move synchronously, adjusting the air direction and air volume of the quench air vents above the crushing box and the guide plate. During crushing, the debris that jumps out of the crushing box will be blown back into the crushing box by the airflow, preventing debris from scattering in the frame and causing equipment failure. After the broken glass has completely moved to the guide plate, the lifting rod can drive the partition to descend rapidly, closing the furnace outlet and preventing subsequent glass from being discharged. When the glass has completely entered the crushing box and no more debris splashes onto the guide plate, the device returns to normal working condition. Then the lifting rod opens the furnace outlet, allowing the discharged glass to be transported and cooled again. Attached Figure Description

A slow cooling air inlet 209 is symmetrically arranged on both sides of the air distribution groove 203 of the fan hood 201. A grid plate 210 is symmetrically rotatably connected in the slow cooling air inlet 209. A transmission groove 211 is provided on one side of the slow cooling air inlet 209 of the fan hood 201. A transmission gear 212 is symmetrically arranged in the transmission groove 211. A rack 213 is provided on one side of the transmission gear 212.

[0028] Please see Figures 1 to 5 The control plate 208 is elastically connected to the control groove 205 via the control spring 207, and the control plate 208 is slidably connected to the fan shroud 201 via the control groove 205. The control plate 208 is L-shaped, and part of the control plate 208 is located inside the quench air inlet 204. The grid plate 210 and the transmission gear 212 are equidistantly arrayed about the fan shroud 201, and the transmission gear 212 is connected to the rotating shaft of the grid plate 210. The transmission gear 212 meshes with the rack 213. A conveying roller 3 is provided on the lower inner side of the frame 1, and a groove 4 is provided on the leftmost conveying roller 3 of the frame 1. A slider 5 is provided in the groove 4, and a telescopic rod 6 is connected to one side of the slider 5. A motor 7 is provided on one side of the frame 1, and a tensioning wheel structure 8 is provided on one side of the frame 1 on the conveying roller 3. A drive gear 9 is connected to the rear end of the leftmost conveying roller 3 of the frame 1. The conveying roller 3 is rotatably connected to the slider 5 via bearings, and the conveying rollers 3 are connected to each other and to the tensioning wheel structure 8 via belts and pulleys. The motor 7 is connected to the leftmost conveying roller 3 via belts and pulleys. A soft pressure roller 10 is provided on the left side of the frame 1 above the conveying roller 3, and slide seats 11 are rotatably connected to both ends of the soft pressure roller 10. The frame 1 is provided with slide rails 12 on both sides of the soft pressure roller 10, and soft pressure springs 13 are connected inside the slide rails 12. The slide seats 11 are slidably connected to the frame 1 via the slide rails 12, and the slide seats 11 are elastically connected to the frame 1 via the soft pressure springs 13. A hydraulic chamber 14 is provided on one side of the slide rails 12, and a stopper plate 15 is provided inside the hydraulic chamber 14. The hydraulic chamber 14 is filled with a high boiling point liquid, and the hydraulic chamber 14 is connected to the connecting channel 206. The stopper plate 15 is connected to the slide seat 11.

[0029] The specific operation is as follows: During the glass conveying process, the blower 202 can send cold air into the air hood 201, and then the glass exiting the furnace is rapidly cooled and slowly cooled successively through the rapid cooling air inlet 204 and the slow cooling air inlet 209. During the rapid cooling process, the soft pressure roller 10 can be pressed against the glass surface under the action of the soft pressure spring 13. When there are protrusions on the glass and the protrusions pass under the soft pressure roller 10, the soft pressure roller 10 can cooperate with the conveying roller 3 to perform initial leveling of the glass under the action of the soft pressure spring 13. At the same time, it will drive the slide block 11 on the slide rail due to the deformation of the glass. The slide 11 moves within the hydraulic chamber 14, compressing the soft spring 13 and simultaneously moving the stopper plate 15 within the hydraulic chamber 14. This forces the liquid in the hydraulic chamber 14 through the connecting channel 206 into the regulating groove 205, causing the regulating plate 208 to move within the regulating groove 205 and the quench air vent 204, stretching the regulating spring 207 and increasing the opening of the quench air vent 204. After passing the protrusion, the slide 11 moves the stopper plate 15 back under the action of the soft spring 13, extracting the liquid from the regulating groove 205. The regulating plate 208 then returns to its original position under the action of the regulating spring 207.

[0030] Please see Figures 2 to 7 A sliding frame 16 is provided on the inner right wall of frame 1, and buffer springs 17 are symmetrically arranged inside the sliding frame 16. One end of the buffer spring 17 is connected to a positioning plate 18, and a rubber plate 19 is connected to one side of the positioning plate 18. A limit rod 20 is connected to the other side of the positioning plate 18. A bottom frame 21 is provided on the lower right part of frame 1 between the conveying rollers 3, and a friction strip 22 is engaged and slidably connected inside the bottom frame 21. The positioning plate 18 is elastically connected to the sliding frame 16 through the buffer spring 17, and the positioning plate 18 and the sliding frame 16 are engaged and slidably connected. The limit rod 20 is connected to the toothed rod 213. The sliding frame 16 is filled with a high-boiling-point liquid, and the sliding frame 16 is connected to the bottom frame 21 through a pipe. A top plate 23 is connected above the slider 5. A control plate 24 is connected between 23. A through groove 25 is opened on the surface of the control plate 24, and the position of the through groove 25 corresponds to the position of the quench air vent 204. A crushing box 26 is set at the lower left of the frame 1. A guide plate 27 is connected to both sides of the upper end of the crushing box 26. A crushing shaft 28 is symmetrically rotated inside the crushing box 26, and a synchronous gear 29 is connected to the rear end of the crushing shaft 28. A waste box 30 is set below the crushing box 26. A bracket 31 is connected to the left end of the frame 1, and a lifting rod 32 is symmetrically connected to the inner side of the bracket 31. A partition 33 is connected to the lower end of the lifting rod 32. A pressure sensor is set inside the guide plate 27. The synchronous gears 29 mesh with each other and mesh with the drive gear 9.

[0031] The specific operation is as follows: After the glass enters the slow cooling section, cold air, guided by the grid plate 210, slowly cools the glass through the slow cooling vent 209. When the edge of the glass contacts the positioning plate 18, the adhesive plate 19 provides initial cushioning for the glass. At the same time, the positioning plate 18 slides within the sliding frame 16 due to the pressure of the glass, compressing the buffer spring 17. As the positioning plate 18 moves, it squeezes the liquid in the sliding frame 16 into the bottom frame 21 through the pipe. Simultaneously, it drives the gear 213 to move within the transmission groove 211 via the limit rod 20, causing the gear 213 to drive the grid plate 210 to rotate within the slow cooling vent 209 via the transmission gear 212. As liquid is injected into the bottom frame 21, the friction strip 22 is lifted by the liquid and contacts the glass. When the glass stops... After movement, the glass will exert pressure on the friction strip 22 under the action of gravity. At the same time, the positioning plate 18 will slowly rebound under the action of the buffer spring 17, thereby drawing the liquid in the bottom frame 21 back into the sliding frame 16 and causing the glass to move back a certain distance. The gear 213 will also be driven by the limiting rod 20 to move back with the rebound of the positioning plate 18. Through the transmission gear 212, the grid plate 210 will rotate in the slow cooling air vent 209. At this time, as the liquid in the bottom frame 21 flows back, the glass will also fall down with the friction strip 22 until it contacts the conveying roller 3. Then, it will be driven by the conveying roller 3 to move again and squeeze the positioning plate 18 again, thus repeating the above process, causing the glass to swing back and forth on the right side of the frame 1. In use, the motor 7 will drive the conveying roller. 3. The mechanism rotates to transport the glass exiting the furnace. When the glass breaks during exiting the furnace, the fragments fall onto the guide plate 27. Upon sensing a pressure change, the pressure sensor inside the guide plate 27 activates the telescopic rod 6, causing the slider 5 to slide within the chute 4. This causes the slider 5 to move the leftmost conveyor roller 3 of the frame 1, clearing the space above the guide plate 27 on the left side of the crushing box 26. The broken glass, no longer supported by the conveyor roller 3, slides along the guide plate 27 into the crushing box 26. As the telescopic rod 6 moves the slider 5, the belt connecting the motor 7 and the conveyor roller 3 loosens due to the movement of the conveyor roller 3. At this point, the conveyor roller 3 stops rotating. When the slider 5 moves to the rightmost end of the chute 4, the drive gear 9... It will mesh with the synchronous gear 29, causing the conveyor roller 3 to drive the crushing shaft 28 to rotate in opposite directions within the crushing box 26 via the drive gear 9 and the synchronous gear 29. At this time, the belt will tighten again, and the motor 7 can drive the conveyor roller 3 to rotate again. When the glass enters the crushing box 26, the crushing shaft 28 can crush the glass. When the slider 5 moves, it can drive the top plate 23 and the air control plate 24 to move synchronously. After the slider 5 stops, the air control plate 24 will close most of the quench air vents 204 on the air cover 201 and keep the quench air vents 204 above the crushing box 26 and the guide plate 27 open. At the same time, the air control plate 24 will change the air direction. After the top plate 23 moves to a stop, it will push the soft pressure roller 10 above the crushing box 26 and the guide plate 27 to rise.The control plate 208 above the crushing chamber 26 and guide plate 27 fully opens the quench air vent 204. During crushing, the debris ejected from the inlet of the crushing chamber 26 is blown back into the crushing chamber 26 by the airflow along the guide plate 27, eventually falling into the waste bin 30. Once the pressure sensor on the guide plate 27 detects that the broken glass has completely moved onto the guide plate 27, the lifting rod 32 causes the partition 33 to descend rapidly. When the glass has completely entered the crushing chamber 26 and no more debris splashes onto the guide plate 27, the telescopic rod 6 can drive the conveying roller 3 to reset via the slider 5, restoring the device to normal operating status. Then, the lifting rod 32 causes the partition 33 to rise.

[0032] In summary, when using this tempered glass manufacturing furnace unloading device, first align the frame 1 with the furnace outlet and place the device, then start the motor 7 and the fan 202. The motor 7 will drive the conveyor roller 3 to rotate and convey the unloaded glass. During the glass conveying process, the fan 202 can send cold air into the air hood 201, and then through the rapid cooling air inlet 204 and the slow cooling air inlet 209, the unloaded glass is rapidly cooled and slowly cooled in sequence, thereby ensuring the successful tempering of the glass and smooth removal of the parts.

[0033] During the rapid cooling process, the soft pressure roller 10 can adhere to the glass surface under the action of the soft pressure spring 13. When there is a protrusion on the glass and the protrusion passes under the soft pressure roller 10, the soft pressure roller 10 can cooperate with the conveyor roller 3 to perform initial leveling of the glass under the action of the soft pressure spring 13. At the same time, it will drive the slide block 11 to move in the slide rail 12 due to the deformation of the glass. While compressing the soft pressure spring 13, it will drive the stop plate 15 to move in the hydraulic chamber 14, and squeeze the liquid in the hydraulic chamber 14 into the regulating groove 205 through the connecting channel 206. This will drive the regulating plate 208 to move in the regulating groove 205 and the rapid cooling air outlet 204 and stretch the regulating spring 207, thereby increasing the opening of the rapid cooling air outlet 204, thereby increasing the cooling air volume received by the glass protrusion, suppressing the protrusion, and preventing the deformation from developing.

[0034] After passing through the protrusion, under the action of the soft pressure spring 13, the slide 11 drives the stop plate 15 to move back, and after the liquid in the control groove 205 is extracted, the control plate 208 can return to its original position under the action of the control spring 207, thereby restoring the air volume to normal, avoiding the glass from shrinking due to excessive cooling and causing dents, and thus ensuring that the glass can be successfully tempered and its surface remains flat.

[0035] After the glass enters the slow cooling section, the cold air will be guided by the grid plate 210 and pass through the slow cooling air outlet 209 to slowly cool the glass. When the edge of the glass comes into contact with the positioning plate 18, the adhesive plate 19 can provide initial buffer for the glass to avoid the glass directly impacting the positioning plate 18 and causing damage. At the same time, the positioning plate 18 will slide in the sliding frame 16 due to the pressure of the glass and compress the buffer spring 17 for secondary buffering. When the positioning plate 18 moves, it will squeeze the liquid in the sliding frame 16 into the bottom frame 21 through the pipe. At the same time, it will also drive the rack 213 to move in the transmission groove 211 through the limit rod 20. The rack 213 will drive the grid plate 210 to rotate in the slow cooling air outlet 209 through the transmission gear 212, thereby adjusting the airflow direction and achieving the effect of wind following the object's movement. This achieves dynamic matching of wind direction with glass displacement.

[0036] As liquid is injected into the bottom frame 21, the friction strip 22 is lifted by the liquid and comes into contact with the glass. This decelerates the glass and pushes it away from the conveyor roller 3, causing the glass to lose its movement power. When the glass stops moving, it will exert pressure on the friction strip 22 under the action of gravity. At the same time, the positioning plate 18 will slowly rebound under the action of the buffer spring 17, thereby drawing the liquid in the bottom frame 21 back into the slide frame 16 and causing the glass to move back a certain distance. The toothed rod 213 will also be driven by the limiting rod 20 to move back along with the rebound of the positioning plate 18. The transmission gear 212 drives the grid plate 210 to rotate in the slow cooling air outlet 209, causing the airflow to return as the glass moves back. At this time, as the liquid in the bottom frame 21 flows back, the glass will also fall along with the friction strip 22 until it contacts the conveyor roller 3. Then, it will be driven by the conveyor roller 3 to move again and squeeze the positioning plate 18 again. This process is repeated, causing the glass to swing back and forth on the right side of the frame 1 until the glass drops to the predetermined temperature and is then picked up. When picking up the glass, simply pausing the conveyor will allow for a smooth glass removal.

[0037] When the glass breaks during the furnace process, the fragments fall onto the guide plate 27. After the pressure sensor inside the guide plate 27 senses the pressure change, the telescopic rod 6 immediately drives the slider 5 to slide in the chute 4, causing the slider 5 to move the leftmost conveyor roller 3 of the frame 1, thus freeing up the space above the guide plate 27 on the left side of the crushing box 26. After losing the support of the conveyor roller 3, the broken glass will slide along the guide plate 27 into the crushing box 26.

[0038] As the telescopic rod 6 moves the slider 5, the belt connecting the motor 7 and the conveyor roller 3 will loosen due to the movement of the conveyor roller 3. At this time, the conveyor roller 3 will stop rotating. When the slider 5 moves to the rightmost end of the chute 4, the drive gear 9 will mesh with the synchronous gear 29, causing the conveyor roller 3 to drive the crushing shaft 28 to rotate in opposite directions in the crushing box 26 through the drive gear 9 and the synchronous gear 29. At this time, the belt will tighten again, and the motor 7 can drive the conveyor roller 3 to rotate again. The belt between the conveyor rollers 3 will always remain taut due to the presence of the tensioning wheel structure 8, so that all the conveyor rollers 3 can rotate synchronously.

[0039] When the glass enters the crushing chamber 26, the crushing shaft 28 can crush the glass. When the slider 5 moves, it can drive the top plate 23 and the air control plate 24 to move synchronously. After the slider 5 stops, the air control plate 24 will close most of the quench air vents 204 on the air cover 201 and keep the quench air vents 204 above the crushing chamber 26 and the guide plate 27 open. At the same time, the air control plate 24 will change the air direction so that the air direction is towards the entrance of the crushing chamber 26.

[0040] When the top plate 23 moves to a stop, it will push the soft pressure roller 10 above the crushing box 26 and the guide plate 27 to rise, causing the control plate 208 above the crushing box 26 and the guide plate 27 to fully open the quench air vent 204, thereby maximizing the air volume of the quench air vent 204 above the crushing box 26 and the guide plate 27. During crushing, the slag that jumps out of the feed port of the crushing box 26 will be blown back into the crushing box 26 by the airflow along the guide plate 27, and finally fall into the waste bin 30, so as to avoid the slag from flying in the frame 1 and causing device failure.

[0041] Once the pressure sensor on the guide plate 27 detects that the broken glass has completely moved onto the guide plate 27, the lifting rod 32 can drive the partition 33 to descend rapidly, sealing the furnace outlet and preventing subsequent glass from being discharged. When the glass has completely entered the crushing box 26 and no more fragments splash onto the guide plate 27, the telescopic rod 6 can drive the conveying roller 3 to reset via the slider 5, allowing the device to return to normal working condition. Then, the lifting rod 32 drives the partition 33 to rise, opening the furnace outlet, allowing the discharged glass to be conveyed and cooled again.
