Description

Technical Field

[0001] This invention relates to the field of glass tempering furnace technology, and specifically to a glass tempering furnace for vehicle-mounted central control screens. Background Technology

[0002] The glass for the vehicle's central control screen is a key component protecting the vehicle's display screen. It is usually made of high-strength tempered glass, which has scratch-resistant and impact-resistant properties. During the production process, the glass for the vehicle's central control screen needs to undergo a tempering process. Glass tempering is a process that improves the mechanical strength of glass through heat treatment. Its core process is to heat the glass to near its softening point in the heating zone of the tempering furnace, and then quickly transfer it to the cooling zone for uniform and rapid cooling, thereby forming compressive stress on the glass surface and tensile stress inside the glass.

[0003] During the heating process, due to inherent defects in the glass (such as stones or bubbles), uneven heating, or thermal shock, the glass is highly susceptible to cracking within the heating zone, a phenomenon commonly known in the industry as "chamber explosion." Once a chamber explosion occurs, the shattered glass will scatter across the conveyor surface comprised of multiple ceramic rollers. To prevent high-temperature glass fragments from adhering to or damaging the ceramic rollers and to ensure smooth subsequent production, these glass fragments must be cleaned up promptly.

[0004] Currently, the conventional method for cleaning broken glass in the heating zone of a tempering furnace is as follows: First, the equipment is immediately shut down, and the upper heating device of the tempering furnace is raised to open the furnace chamber and allow for natural or forced cooling. Once the furnace temperature has dropped to a level where personnel can barely approach, operators use long poles or other tools to reach into the furnace from the outside and manually knock and move the broken glass on the ceramic roller conveyor. The purpose is to break large pieces of glass into smaller fragments so that they can fall through the gaps between the ceramic rollers into the ash collection bin below. Finally, the ash collection bin is cleaned.

[0005] However, this cleaning method has the following drawbacks:

[0006] First, although the furnace body has undergone initial cooling, the internal environment and the broken glass itself remain at temperatures of several hundred degrees Celsius. Operators working at close range face the risk of being exposed to intense heat and suffering burns. Additionally, the hot glass shards that scatter during forceful striking can also cause injury.

[0007] Secondly, the ceramic roller conveyor is a core conveying component in the heating zone of the tempering furnace. It is brittle and expensive. In poor visibility and limited operating space, the accuracy of manually striking it with a long pole is difficult to guarantee, making it very easy to accidentally hit the ceramic roller conveyor, causing surface damage or even breakage. Once the ceramic roller conveyor is damaged, not only are repair and replacement costs high, but it also leads to a prolonged shutdown of the entire tempering production line, resulting in huge economic losses.

[0008] Finally, due to the high temperature and structural limitations inside the furnace, operators cannot enter to conduct a comprehensive and thorough inspection and cleaning. Inevitably, some small glass fragments or glass debris will remain, either small or stuck on the sides of the roller conveyor. These residues can scratch the surface of newly placed glass sheets during subsequent production, leading to quality defects such as scratches and a decrease in yield. Summary of the Invention

[0049] Example

[0050] To address the technical problems in the background section, the following is proposed: a tempering furnace for in-vehicle central control screen glass.

[0051] Combination Figures 1-13As shown, the present invention provides a vehicle-mounted central control screen glass tempering furnace, including a base 100; a conveying heating device 200 is installed on the top surface of the base 100; a crushing and cleaning device 300 is installed on the top surface of the base 100 above the conveying heating device 200; an upper heating device 400 is installed above the crushing and cleaning device 300; a transfer conveying device 500 is installed on the top surface of the base 100 at the unloading end of the conveying heating device 200; and a transfer conveying device 500 is installed on the top surface of the base 100 at the unloading end of the transfer conveying device 200. The feeding end of the conveying device 500 is equipped with an external roller conveyor belt 600, and the surface of the conveying heating device 200 conveys the vehicle central control screen glass 700; the crushing and cleaning device 300 includes a crushing frame 301, the crushing frame 301 is fixedly connected to the top surface of the base 100, and the two sides of the inner wall of the crushing frame 301 are respectively rotatably connected to a driving sprocket 302 and a driven sprocket 303. There are three sets of driven sprockets 303. The surface of the driving sprocket 302 is rotatably connected to the driven sprocket 303 via a suspension chain 304. The device includes a drive sprocket 303 and two sets of suspension chains 304. The suspension chains 304 are U-shaped. A crushing and cleaning component is installed between the two sets of suspension chains 304. A drive motor 305 is fixedly connected to both sides of the surface of the crushing frame 301. The output end of the drive motor 305 is connected to the drive sprocket 302 through a worm gear and worm wheel. The crushing and cleaning component includes a long plate 306. Both ends of the long plate 306 are fixedly connected to the suspension chains 304. A crushing and cleaning component is installed on one side of the long plate 306, and an interception component is installed on one side of the crushing and cleaning component. A cooling observation component is installed on the other side of the long plate 306, and a grinding component is installed on one side of the cooling observation component. The cooling observation component includes a hollow box 307. A hollow box 307 is fixedly connected to the other side of the long plate 306. Observation cameras 308 are fixedly connected at equal intervals on the bottom surface of the hollow box 307. Air jet pipes 309 are fixedly connected at equal intervals on the bottom surface of the hollow box 307 between every two sets of observation cameras 308.

[0052] By integrating modules such as a conveying heating device, a crushing and cleaning device, and an upper heating device into the base, the entire process of glass conveying, heating, tempering, and post-burst cleaning is automated without the need to disassemble the equipment.

[0053] The crushing frame drives the suspension chain (with an open design) via a drive sprocket and a driven sprocket, which in turn drives the crushing and cleaning components to fully cover the heating device, ensuring thorough cleaning without any blind spots.

[0054] The air jet pipe of the hollow box achieves the dual function of cooling the broken glass and the observation camera, avoiding damage to the camera due to high temperature. At the same time, the observation camera locates the broken glass in real time, providing accurate information for cleaning.

[0055] The conveying heating device can not only convey the glass, but also heat the bottom surface of the glass during conveying. At the same time, when broken glass falls into the interior later, it not only collects the broken glass, but also facilitates centralized processing later.

[0056] The broken glass can be cleaned by the crushing and cleaning device, which prevents glass residue from remaining on the ceramic roller and can also clean the surface of the ceramic roller and heating wire.

[0057] The top surface of the glass can be heated by the upper heating device, and the glass can be monitored at all times during the heating process.

[0058] The transfer and conveying device not only facilitates the transfer and conveying of glass, but also makes it convenient to store and collect the breakage and cleaning equipment later.

[0059] In this embodiment, the crushing and cleaning component includes a pneumatic reciprocating track 310. A pneumatic reciprocating track 310 is installed on one side of a long plate 306. A crushing pneumatic rod 311 is symmetrically and fixedly connected to the bottom surface of the pneumatic reciprocating track 310. An arc-shaped block 312 is fixedly connected to the output end of the crushing pneumatic rod 311. An air box 313 is rotatably connected inside the arc-shaped block 312. A brush 314 is fixedly connected to the top surface of the air box 313. A crushing rod 315 is fixedly connected at equal intervals to the bottom surface of the air box 313. Air holes 316 are provided at equal intervals to the bottom surface of the air box 313. A switching gear 317 is fixedly connected to one end of the air box 313. A switching pneumatic rod 318 is fixedly connected to one side of the arc-shaped block 312. A switching rack 319 is fixedly connected to the output end of the switching pneumatic rod 318. The switching rack 319 meshes with the switching gear 317.

[0060] The air box is moved down by the crushing pneumatic rod, and the crushing rod breaks the large pieces of glass into a size that can be dropped (falling into the receiving box from the gap between the ceramic rollers). At the same time, air is sprayed from the air holes on the bottom of the air box to blow away the residual debris on the surface of the ceramic rollers and heating wires.

[0061] The switching pneumatic rod drives the switching rack to mesh with the switching gear, realizing the air box flipping (crushing rod facing up / brush facing down). The brush can be used to clean residual dust, and the crushing rod can be used for crushing operations. No component replacement is required.

[0062] The pneumatic reciprocating track drives the crushing components to move back and forth, adapting to the cleaning needs of different areas. The arc-shaped block and the air box are connected to ensure the flexibility of the flipping mechanism.

[0063] In this embodiment, the interception component includes a side frame 320. The side frame 320 is installed on one side of the pneumatic reciprocating track 310. An avoidance damping rod 321 is installed on the bottom surface of the side frame 320. A cleaning plate 322 is fixedly connected to one end of the avoidance damping rod 321.

[0064] A protective barrier is formed by the cleaning plate under the side frame to intercept glass shards that fly when the equipment breaks, ensuring the safety of the area around the equipment;

[0065] The avoidance damping rod provides a buffering force, which can adaptively avoid the cleaning plate when it encounters stubborn residue or protrusions, avoiding hard scratching that could damage the heating wire or the cleaning plate, while ensuring that the scraping force is appropriate for the residue.

[0066] The cleaning plate moves synchronously with the crushing and cleaning components, enabling the simultaneous formation of obstructions during crushing and the scraping of obstructions during movement, thereby improving cleaning efficiency.

[0067] In this embodiment, the grinding component includes a downward pneumatic rod 323. The downward pneumatic rod 323 is fixedly connected to one side of the hollow box 307. An L-shaped plate 324 is fixedly connected to the output end of the downward pneumatic rod 323. A protective damping rod 325 is fixedly connected at equal intervals to one side of the L-shaped plate 324. A gantry frame 326 is fixedly connected to one end of the protective damping rod 325. A first flip motor 327 is fixedly connected to one side of the gantry frame 326. A vertical plate 328 is rotatably connected to the output end of the first flip motor 327 through a worm gear and worm wheel. A C-shaped shell 329 is fixedly connected to one side of the vertical plate 328. Sandpaper 330 is slidably connected inside the C-shaped shell 329.

[0068] The first flipping motor drives the upright plate to rotate, switching the sandpaper from a vertical storage state to a horizontal working state. The pneumatic rod is pressed down to push the sandpaper to adhere to the surface of the ceramic roller / heating wire. The rotation of the ceramic roller achieves polishing and thoroughly removes stubborn residue.

[0069] The protective damping rod buffers the grinding pressure, preventing excessive sandpaper pressure from causing wear on the equipment surface. The C-shaped shell is adapted to the shape of the ceramic roller to ensure a good fit during grinding.

[0070] When not in a sanding state, the sandpaper can be stored vertically with the stand, without affecting other operations such as breaking and cleaning. At the same time, vertical storage can also prevent the glass shards from flying when breaking glass.

[0071] The design of the C-shaped shell 329 will facilitate the quick replacement of sandpaper 330 by staff. When replacing, the sandpaper 330 is pulled out from one side, and then inserted into the C-shaped shell 329 from one end. The inserted sandpaper can not only shape the sandpaper, but also prevent the sandpaper from falling off.

[0072] In this embodiment, the conveying heating device 200 includes a U-shaped receiving box 201. The U-shaped receiving box 201 is fixedly connected to the top surface of the base 100. A scraping assembly is installed on the inner wall of the U-shaped receiving box 201. A discharge port 202 is provided at one end of the bottom of the inner cavity of the U-shaped receiving box 201. A sealing discharge assembly is installed in the discharge port 202. A sealing plate 203 is fixedly connected to one end of the U-shaped receiving box 201 and located at the discharge port 202. A conveying assembly is installed on the top surface of the U-shaped receiving box 201.

[0073] The U-shaped receiving box, sealing plate, and scraper form a closed cavity, reducing the leakage of hot air when the heating wire is heating and improving energy utilization.

[0074] The U-shaped receiving box catches broken glass falling from the gap between the ceramic rollers, preventing it from scattering and accumulating, and providing a foundation for subsequent scraping and slag removal;

[0075] The conveying assembly is integrated with the U-shaped receiving box. During the conveying process, the glass is simultaneously heated by the bottom heating wire. With the addition of a heating device, it achieves double-sided heating from the top and bottom, improving the uniformity of tempering.

[0076] In this embodiment, the scraping assembly includes a scraping groove 204 and a dual-axis motor 205. The scraping groove 204 is symmetrically arranged on the inner wall of the U-shaped receiving box 201. A scraping screw 206 is rotatably connected inside the scraping groove 204. A scraper 207 is threadedly connected to the surface of the scraping screw 206. The bottom surface of the scraper 207 is in contact with the bottom surface of the inner wall of the U-shaped receiving box 201. A dual-axis motor 205 is fixedly connected to one side of the sealing plate 203. The output shaft end of the dual-axis motor 205 is rotatably connected to the scraping screw 206 through a worm gear and worm wheel.

[0077] The dual-axis motor drives the scraper screw to rotate through the worm gear, which in turn moves the scraper along the scraper chute to concentrate the broken glass in the receiving box from a dispersed state to the discharge port without manual intervention.

[0078] The bottom surface of the scraper is in close contact with the inner wall of the receiving box, and can scrape off the debris stuck to the bottom during movement, avoiding residue in the corners;

[0079] The dual-axis motor synchronously drives the scraper screws on both sides to ensure that the scraper is subjected to uniform force, moves smoothly, and avoids jamming.

[0080] In this embodiment, the sealed feeding assembly includes a triangular plate 208, a flipping shaft 209, a translational slide rail 210, and a long groove 211. The bottom surface of the U-shaped receiving box 201, located on both sides of the feeding port 202, is fixedly connected to the triangular plate 208. The flipping shaft 209 is rotatably connected inside the feeding port 202. A flipping plate 212 is fixedly connected to the surface of the flipping shaft 209. Flipping gears 213 are fixedly connected to both ends of the surface of the flipping shaft 209. Translational slide rails 210 and long grooves 211 are fixedly connected to both sides of the U-shaped receiving box 201. The surface of the sliding rail 210 is slidably connected to a rotating rack 214, which meshes with a rotating gear 213. One end of the rotating rack 214 is fixedly connected to a reset damping rod 215 located between the surface of the U-shaped receiving box 201. One side of the rotating rack 214 is fixedly connected to a push rod 216. Long grooves 211 are respectively provided on both sides of the U-shaped receiving box 201. The long grooves 211 communicate with the scraping groove 204. One end of the push rod 216 slides within the long groove 211.

[0081] When the scraper moves to the discharge port, it pushes the push rod, which drives the tilting rack to slide along the translation slide rail. The tilting gear meshes with the tilting gear to drive the tilting shaft to rotate, and the tilting plate automatically opens the discharge port, realizing the synchronous linkage of scraping and slag discharge.

[0082] After the slag discharge is completed, the reset damping rod pulls the tilting rack back to its original position, the tilting plate closes the discharge port, restores the sealing of the receiving box, and reduces heat loss;

[0083] The triangular plate guides the broken glass to slide down the tilting plate into the receiving box, preventing it from scattering during slag discharge.

[0084] In this embodiment, the conveying assembly includes a motor plate 217, a first ceramic strip 218, a second ceramic strip 219, and a ceramic roller 220. The first ceramic strip 218 and the second ceramic strip 219 are fixedly connected to the two ends of the top surface of the U-shaped receiving box 201, respectively. The two ends of the ceramic roller 220 rotate within the first ceramic strip 218 and the second ceramic strip 219, respectively. The surface of the ceramic roller 220 is wound with an electric heating wire 221. The lower part of one side of the U-shaped receiving box 201 is fixedly connected to the motor plate 217. The top surface of the motor plate 217 is rotatably connected to a long shaft 222. The surface of the long shaft 222 is rotatably connected to the ceramic roller 220 through a pulley and belt. The bottom surface of the motor plate 217 is fixedly connected to a conveying motor 223. The output end of the conveying motor 223 is rotatably connected to the long shaft 222 through a sprocket assembly.

[0085] By winding heating wires around the surface of the ceramic roller, the glass comes into direct contact with the ceramic roller, achieving uniform heating at the bottom. Combined with the heating device, this forms coordinated heating from top to bottom, improving the tempering effect.

[0086] The conveyor motor drives a long shaft through a sprocket set, which in turn drives multiple sets of ceramic rollers to rotate synchronously via belt pulleys, ensuring smooth glass conveying and preventing deviation.

[0087] The first and second ceramic strips position the two ends of the ceramic roller, and the motor plate integrates the conveyor motor and the long shaft, reducing the space occupied by the equipment and improving the structural stability.

[0088] In this embodiment, the upper heating device 400 includes lifting hydraulic rods 401. The top surface of the crushing frame 301 is fixedly connected to the lifting hydraulic rods 401. There are four sets of lifting hydraulic rods 401. The output end of the lifting hydraulic rods 401 is fixedly connected to the upper hot air hood 402. The top surface of the upper hot air hood 402 is symmetrically fixedly connected to the air inlet pipe 403. The top surface of the inner wall of the upper hot air hood 402 is fixedly connected to high-temperature resistant cameras 404 at equal intervals. The lower part of the inner cavity of the upper hot air hood 402 is fixedly connected to the barrier rod 405. The upper surface of the barrier rod 405 is fixedly connected to the heating wire 406.

[0089] The upper hot air hood is raised and lowered by four sets of lifting hydraulic rods. After the explosion, the hot air hood is raised to quickly dissipate hot air and provide ample cleaning space, thus improving the safety of the operation.

[0090] High-temperature resistant cameras capture the glass heating status in real time, promptly identifying any explosions and providing a basis for staff to respond quickly.

[0091] The air inlet duct connects to hot air, and the upper hot air hood forms a closed heating space. The hot air circulates and, together with the heating wire on the baffle rod, achieves uniform heating of the upper surface of the glass, improving the tempering quality.

[0092] In this embodiment, the transfer conveying device 500 includes a roller conveyor 501 and a U-shaped frame 502. A drive shaft 503 and a driven shaft 504 are fixedly connected to both sides of one end of the roller conveyor 501, and an extension rod 505 is fixedly connected to both sides of the other end of the roller conveyor 501. The bottom surface of the extension rod 505 is in contact with the top surface of the U-shaped frame 502. The drive shaft 503 and the driven shaft 504 are rotatably connected inside the U-shaped frame 502. A second tilting motor 506 is fixedly connected to one side of the U-shaped frame 502. The output end of the second tilting motor 506 is rotatably connected to the drive shaft 503 through a worm gear and worm wheel.

[0093] The second flipping motor drives the drive shaft to rotate, causing the roller conveyor to flip from a horizontal conveying state to a vertical storage state, exposing the crushing and cleaning components below and avoiding spatial interference;

[0094] The roller conveyor, through the cooperation of the drive shaft, driven shaft and U-shaped frame, ensures that the glass is smoothly transferred from the conveying heating device to the external roller conveyor belt, reducing deviation;

[0095] During normal tempering, it is conveyed horizontally, and during cleaning operations, it is stored vertically without disassembling components, enabling rapid switching between operating states and improving equipment utilization.

[0096] Working principle and usage process of this invention:

[0097] In use:

[0098] When tempering glass by heating:

[0099] First, the glass to be tempered is conveyed onto the ceramic roller 220 via an external conveyor roller. Then, the conveyor motor 223 is started, which drives the long shaft 222 to rotate via a sprocket and chain. When the long shaft 222 rotates, it drives multiple sets of ceramic rollers 220 to rotate with the help of multiple pulleys and belts. When the ceramic rollers 220 rotate, they start to convey the glass forward. During the conveying process, the heating wire 221 and heating wire 406 are activated respectively. At this time, the heating wire 221 and heating wire 406 can heat both sides of the glass, making the glass soften. At the same time, by connecting the air inlet pipe 403 to an external fan, hot air is injected into the upward hot air hood 402, which blows the hot air onto the glass, creating convection inside and better heating the glass. While the glass is being heated, the heating process can be monitored in real time by the high-temperature resistant camera 404.

[0100] After the glass is heated and softened, it will be conveyed out from below the upper hot air hood 402 by the ceramic roller 220. After being conveyed out, the softened glass will be conveyed to the transfer conveyor 500. At this time, the glass will be conveyed to the external roller conveyor belt 600 by the roller conveyor 501 on the transfer conveyor 500. Finally, it will enter the external cooling equipment for cooling and tempering, which will increase the hardness of the glass.

[0101] Because the U-shaped receiving box 201, scraper 207 and sealing plate 203 cooperate to form a sealed box, when the heating wire 221 heats the vehicle central control screen glass 700, the generated hot air will be retained in the sealed box to prevent the hot air from escaping and causing waste.

[0102] When the vehicle's central control screen glass 700 shatters between the upper heating device 400 and the conveying heating device 200 (the shattering will be captured by the high-temperature resistant camera 404, and will also be visible to outsiders through the screen), the following measures will be taken:

[0103] First, the staff quickly shut down the conveyor motor 223, heating wire 221, heating wire 406, roller conveyor 501, and the external fan. After all these are shut down, the lifting hydraulic rod 401 is activated. When the lifting hydraulic rod 401 is working, it will move the upper hot air hood 402 upward, moving it away from the U-shaped receiving box 201. This allows the hot air between the upper hot air hood 402 and the U-shaped receiving box 201 to dissipate quickly, cooling the cracked glass.

[0104] The second step involves the staff starting the second tilting motor 506. As the second tilting motor 506 operates, it drives the drive shaft 503 to rotate via a worm gear and worm wheel. When the drive shaft 503 rotates, it drives the roller conveyor 501 to rotate along the drive shaft 503 under the action of the driven shaft 504. When the roller conveyor 501 rotates, it rotates from a horizontal position to a vertical position, thereby exposing the broken glass cleaning components stored below the roller conveyor 501, which facilitates the subsequent processing of broken glass.

[0105] The third step is to begin cleaning the broken glass, and at the same time, clean the surfaces of the ceramic roller 220 and the heating wire 221. The cleaning method is as follows:

[0106] S1. The staff starts the drive motor 305. As the drive motor 305 works, it will drive the drive sprocket 302 to rotate. When the drive sprocket 302 rotates, it will drive the suspension sprocket 304 to rotate under the action of the driven sprocket 303. When the suspension chain 304 rotates, it will start to move the crushing and cleaning components below the transfer conveyor 500 onto the two sets of ceramic rollers 220.

[0107] S2. An external blower begins to inject air into the air box 313 and the hollow box 307 respectively. When air is injected into the hollow box 307, the air will be ejected from the jet pipe 309. When it is ejected, it begins to cool down the broken glass. During the cooling process, the blown air can also cool down the observation camera 308. The observation camera 308 may be damaged due to high temperature. The observation camera 308 can view the broken glass and its location so that the position of the breaking rod 315 can be adjusted later.

[0108] S3. After the shattered glass is cooled, the breaking rod 315 will move above the cooled glass and be positioned between the two sets of ceramic rollers 220. The jet pipe 309 will move forward to cool the lower piece of glass. When the breaking rod 315 is above the shattered glass, the breaking pneumatic rod 311 is activated. The operation of the breaking pneumatic rod 311 will drive the breaking rod 315 downwards. As the breaking rod 315 moves downwards, it begins to break the shattered glass into smaller pieces. The glass is broken again, and the broken glass will fall between the two sets of ceramic rollers 220. The falling glass fragments will fall into the U-shaped receiving box 201. While the breaking rod 315 is breaking the glass, the air in the air box 313 will be ejected from the air hole 316. The ejected air will start to blow away the glass fragments remaining on the surface of the ceramic rollers 220 and the heating wire 221, so that the glass fragments are blown off the ceramic rollers 220 and the heating wire 221.

[0109] When the breaker bar 315 is breaking the glass, in order to prevent the broken glass from splattering, the intercepting component and the grinding component will start to intercept the splattered glass to prevent the glass from splattering to both sides.

[0110] S4. After the glass on the first set of ceramic rollers 220 is cleaned, the crushing rod 315 will be conveyed to the top of the second set of ceramic rollers 220 under the action of the suspension chain 304. At the same time, the jet pipe 309 will also be conveyed from the second set to the top of the third set of ceramic rollers 220. As the crushing rod 315 moves, it will also drive the cleaning plate 332 to move forward. As the cleaning plate 332 moves forward, it will start to scrape off the broken glass adhering to the heating wire 221. If it cannot be scraped off, the cleaning plate 332 will pass over the broken glass and squeeze the damping rod 321 to facilitate the cleaning plate 332 to clean the surface of the next set of ceramic rollers 220 and heating wire 221 later.

[0111] After all the broken glass on the ceramic rollers 220 has been cleaned, the crushing and cleaning assembly will move from one end of the conveying heating device 200 to the other end. When the crushing and cleaning assembly reaches the other end of the conveying heating device 200, it will be switched and returned along the original path. On the return trip, the ceramic rollers 220 and heating wires 221 need to be cleaned again.

[0112] During switching, firstly, the crushing pneumatic rod 311 is activated. As the crushing pneumatic rod 311 works, it drives the air box 313 to move downwards. When it reaches the appropriate position, the switching pneumatic rod 318 is activated. As the switching pneumatic rod 318 works, it drives the switching rack 319 to move, thereby driving the switching gear 317 to rotate. When the switching gear 317 rotates, it drives the air box 313 to flip. When the pneumatic box 313 flips, the crushing rod 315 is flipped to the top, while the brush 314 is flipped to the bottom. After flipping, the crushing pneumatic rod 311 is activated again to raise the brush 314, making it easier to clean the ceramic roller 220 and the heating wire 221 again later.

[0113] As the crushing and cleaning device 300 moves backward, the conveyor motor 223 can be started before the backward movement. The conveyor motor 223 will drive the long shaft 222 to rotate, which in turn will drive the ceramic roller 220 to rotate. As the crushing and cleaning device 300 moves backward, the cleaning plate 322 moves forward, followed by the brush 314. The brush 314 begins to clean the surfaces of the ceramic roller 220 and the heating wire 221. After cleaning, the observation camera checks for any glass shards remaining on the surfaces of the ceramic roller 220 and the heating wire 221. Simultaneously, the gas ejected from the jet pipe 309 also begins to clean the surfaces of the heating wire 221 and the ceramic roller 220. If the observation camera 308 observes any residue on the surface of the heating wire 221... When glass residue remains, the first tilting motor 327 is activated. When the first tilting motor 327 is working, it drives the vertical plate 328 to rotate via a worm gear and worm wheel. As the vertical plate 328 rotates, it drives the C-shaped shell 329 and sandpaper 330 to rotate, changing the vertical position of the vertical plate 328 to a horizontal position. After this change, the first tilting motor 327 stops working. Simultaneously, the downward-pressing pneumatic rod 323 begins to operate. When the downward-pressing pneumatic rod 323 operates, it drives the L-shaped plate 324, the protective damping rod 325, the gantry frame 326, the C-shaped shell 329, and the sandpaper 330 to move downwards. When the C-shaped shell 329 is engaged with the surface of the ceramic roller 220, the surface of the sandpaper 330 will adhere to the surface to be polished. At this point, the rotation of the ceramic roller 220 begins to use the sandpaper 330 to polish the glass adhering to the surface.

[0114] After all the ceramic rollers 220 and heating wires 221 have been cleaned, the conveying heating assembly will be moved to the transfer conveying device 500 and stored away.

[0115] When it is necessary to clean and maintain the surface of ceramic roller 220 and heating wire 221 in the later stage, only sandpaper and brush are needed to clean and maintain the surface of ceramic roller 220.

[0116] When it is necessary to clean the broken glass inside the U-shaped receiving box 201, the cleaning method is as follows:

[0117] First, the dual-axis motor 205 is started. As the dual-axis motor 205 operates, it drives the scraper screw 206 to rotate. When the scraper screw 206 rotates, it drives the scraper 207 to move. As the scraper 207 moves, it begins to scrape the broken glass forward. When the scraper 207 moves to the push rod 216, it contacts one side of the push rod 216 and pushes the push rod 216 to move. As the push rod 216 moves, it drives the rotating rack 21... 4. As the rack moves, the tilting rack 214 stretches and resets the damping rod 215. As the tilting rack 214 moves, it drives the tilting gear 213 to rotate. When the tilting gear 213 rotates, it drives the tilting plate 212 to rotate. When the tilting plate 212 rotates, the discharge port 202 is opened. At this time, the cleaned broken glass will slide down along the tilting plate 212 and the triangular button 208, thus falling into the receiving box below, which is convenient for the staff to clean up later.
