Continuously pulling the fixed handle 307 can connect the extension chamber 200 with the annealing chamber 101, and at this time drive the motor 208, and the output end of the motor 208 will drive one of the rotating shafts 203 to rotate, so that the rotating rotating shaft 203 drives the other rotating shaft 203 to rotate through the cooperation of the pulley 205 and the belt 206, so that the two rotating shafts 203 rotate in the same direction at the same time, and the two rotating rotating shafts 203 will respectively drive the two linkage gears 204 above to rotate.

When the two movable blocks 309 are flipped, the rotating movable block 309 will rotate on the fixed shaft 313 through the rotating hole 312 to achieve The flip effect is that the movable block 309 rotates and compresses the torsion spring 314 through the cooperation with the rotating hole 312 and drives the arc block 310 to disengage from the arc groove 311, thereby releasing the restriction on the fixed handle 307. Then, the fixed handle 307 is pulled, and the movement of the fixed handle 307 drives the baffle 301 to move, and then the baffle 301 drives the two limiting blocks 316 to slide in the two limiting grooves 315 respectively, thereby limiting the moving direction of the baffle 301, preventing the baffle 301 from deflecting, and continuously pulling The fixed handle 307 can connect the extension chamber 200 with the annealing chamber 101, and the screw rod 306 is rotated.

The continuously moving sliding bar 405 will drive the card slot 407 on the limit block 406 to disengage from the fixed block 408, thereby releasing the restriction on the sealing cover 402, and then flip the sealing cover 402 to drive the connecting bar 401 to flip on the two connecting blocks 400, so that the extension compartment 200 can be opened, and then flip the two movable blocks 309, and the rotating movable block 309 will rotate on the fixed shaft 313 through the rotating hole 312 to achieve the flipping effect. When the movable block 309 rotates, it will compress the torsion spring 314 by cooperating with the rotating hole 312 and bring The movable arc block 310 disengages from the arc groove 311, thereby releasing the restriction on the fixed handle 307. Then, the fixed handle 307 is pulled. The movement of the fixed handle 307 drives the baffle 301 to move, and the baffle 301 drives the two restriction blocks 316 to slide in the two restriction grooves 315 respectively, thereby limiting the movement direction of the baffle 301 and preventing the baffle 301 from deflecting. Continuously pulling the fixed handle 307 can connect the extension chamber 200 with the annealing chamber 101. At this time, the driving motor 208, and the output end of the motor 208 will drive one of the rotating shafts 203 to rotate, so that the rotating rotating shaft 203 drives the other rotating shaft 203 to rotate through the cooperation of the pulley 205 and the belt 206, so that the two rotating shafts 203 are synchronized. When the material plate 201 is moved, the two limiting grooves 209 will slide on the two limiting bars 210 respectively, thereby preventing the material plate 201 from deviating. The continuously moving material plate 201 will drive the two limiting grooves 209 to slide onto the two fixed bars 211, and at the same time, the material plate 201 will drive the fixed rack 202 to move to the other two linkage gears 204, so that the other two rotating linkage gears 204 can continuously transport the material plate 201, and the material plate 201 will be moved. 01 is transported to the outlet of the extension bin 200, the material can be discharged, and then the loading can be completed by following the reverse steps. The workpiece can be annealed in the temperature-controlled energy-saving annealing furnace 100. During the annealing process, the sealing cover 402 and the baffle 301 are closed, and the hot air generated in the annealing bin 101 will enter the extension bin 200 through the connecting holes 304 on the baffle 301 and the movable plate 303, so that the extension bin 200 has a certain temperature. When the workpiece needs to be taken out, the screw rod 306 is rotated. While the screw rod 306 rotates, it will also rotate on the connecting handle 305 and pull the connecting handle 305 to move by cooperating with the fixed handle 307. The moving connecting handle 305 will drive the movable plate 303 to move in the movable groove 302 on the baffle 301.As the movable plate 303 moves, the connecting hole 304 is displaced from the connecting hole 304 on the movable plate 303, thereby completely sealing the baffle 301. The baffle 301 is then fully opened, and the motor 208 is driven to deliver the workpiece to the exit of the extension chamber 200. The baffle 301 is then closed to prevent the heat in the annealing chamber 101 from escaping. The sealing cover 402 is then opened to remove the workpiece.
