[0043] The implementation principle of a tempering furnace for producing fireproof double-glazed insulating glass in this application embodiment is as follows: The drive motor 201 is operated, and the output end of the drive motor 201 rotates the threaded rod 202, causing the threaded slider 203 to drive the connecting rod 204 to slide along the surface of the threaded rod 202 and the inner wall of the T-shaped groove 205. This causes the connecting rod 204 to drive the rotary motor 206, which in turn drives the rotating rod 207. The rotating rod 207 drives the connecting block 208, which pulls the glass limiting block 209. The glass limiting block 209 pulls the connecting slide rod 210, causing the connecting slide rod 210 to slide along the inner wall of the limiting shell 211. Simultaneously, the limiting shell 211 drives the fixing rod 212, which pulls the limiting connecting rod 213, thus limiting the connecting rod 213. Rod 213 pulls the rotating shaft 214 to rotate around the central rod 215, thereby causing the rotating shaft 214 to push the limiting connecting rod 216. The limiting connecting rod 216 pushes the connecting slide rod 218, which in turn pushes the glass limiting block 219. This causes the glass limiting block 209 and the glass limiting block 219 to slide outwards simultaneously, thus disengaging the glass 217 from the glass limiting blocks 209 and 219. Simultaneously, the glass limiting block 219 drives the rotating rod 220 to slide outwards along the inner wall of the tempering furnace 1. Furthermore, the symmetrically arranged T-shaped limiting blocks 223 can be slid along the inner wall of the adjusting groove 222, and then the limiting bolt 224 can be adjusted to limit the width of glass 217, thereby increasing... The device's flexibility and applicability are enhanced by the following: after glass limiting block 209 and glass limiting block 219 limit the glass 217, the rotary motor 206 rotates the rotating rod 207, which in turn rotates the connecting block 208. The connecting block 208 then rotates the glass limiting block 209, which in turn rotates the connecting slide rod 210. The connecting slide rod 210 then rotates the limiting outer shell 211, which in turn rotates the connecting slide rod 218. The connecting slide rod 218 then rotates the glass limiting block 219, which in turn rotates the rotating rod 220. This causes glass limiting blocks 209 and 219 to rotate the glass 217, thereby allowing the glass 217 inside the tempering furnace 1 to enter... The glass 217 is processed to ensure uniform heating and increase its mass. During installation and removal of the glass 217, the drive motor 301 is operated, and the output end of the drive motor 301 rotates the threaded rod 302, causing the threaded slider 303 to drive the connecting rod 304 to slide along the surface of the threaded rod 302. At the same time, the connecting rod 304 drives the linkage plate 306, and the linkage plate 306 drives the connecting plate 308 to slide along the inner wall of the guide groove 307. Simultaneously, the connecting plate 308 drives the limiting rubber 309 to slide along the surface of the glass 217, thereby supporting the upper and lower surfaces of the glass 217, facilitating clamping operations on the glass 217, and making it easy to remove the glass 217 after heating, thus increasing operational stability.
