At the same time, the staff pours quartz sand into the inner cavity of the heating box 301 from the feed port 1013 provided above the installation shell 101; Step 2: The staff starts the servo motor 201 again, and the servo motor 201 will be able to drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it will be able to drive the driving gear 2012 to rotate. When the driving gear 2012 rotates, it will be able to drive the gear ring 2013 to rotate. When the gear ring 2013 rotates, it will be able to drive the heating box 301 to rotate. When the heating box 301 rotates, it will be able to drive the circular mounting plate 3012 to rotate through the conical connecting rod 3011. When the circular mounting plate 3012 rotates, it will be able to drive the rotating shaft 302 to rotate, because the rotating shaft 302 is provided with a guide slot 3021, and the inner cavity of the guide slot 3021 is slidably provided with a guide slider 3022, and the outer wall of the guide slider 3022 is connected to the limit rod 3023, and the limit rod 302 3 is connected to the guide sleeve 3024, and the outer wall of the guide sleeve 3024 is provided with a first sliding mechanism, so that the guide sleeve 3024 can move vertically downward, wherein the first sliding groove 3025 in the first sliding mechanism is provided in the inner cavity of the protective tube 3013, and the first sliding block 3026 slidably installed in the inner cavity of the first sliding groove 3025 is fixedly connected to the guide sleeve 3024, because the outer wall of the protective tube 3013 is fixedly connected with the fixing rod 3014, and the fixing rod 3014 is fixedly connected to the connecting rod 3015 at the bottom, and the connecting rod 3015 movably passes through the circular ring placement plate 501, and the bottom end is fixedly connected with the circular ring mounting plate 3016, wherein the circular ring mounting plate 3016 is connected to the outer wall of the mounting shell 101 through the positioning plate 3017, so that it can be ensured that the protective tube 3013 will not rotate; Step 3: When the guide sleeve 3024 moves vertically downward, the moving rod 3027 can be driven to move vertically downward, and the moving rod 3027 can drive the circular moving plate 3028 to move vertically downward. When the circular moving plate 3028 moves vertically downward, the mounting rod 5041 can be driven to move vertically downward, thereby driving the conical plate 504 to move downward; Step 4: When the circular movable plate 3028 moves to a certain position, it will be able to squeeze the annular plug-in plate 503 to move vertically downward with the assistance of the slide rail 5022, and at this time the conical plate 504 continues to move downward; until the annular plug-in plate 503 moves to a certain position, at this time, the second rectangular notch 5031 opened on the annular plug-in plate 503 and the first rectangular notch 5021 opened on the annular plug-in plate 503 are in a semi-closed state, so that the quartz sand accumulated on the annular placing plate 501 at the outer wall of the annular sleeve tube 502 can slowly enter the inner ring of the annular sleeve tube 502 and be located above the conical plate 504, until the second rectangular notch 5031 and the first rectangular notch 5021 are aligned, then they are fully opened, so that the quartz sand can be quickly introduced to the top of the conical plate 504, and at this time the guide sleeve The upward movement of 3024 will be able to drive the circular movable plate 3028 to move upward, so that the conical plate 504 at this time drives the quartz sand above to move upward, and at the same time the circular movable plate 3028 will lose the squeezing force on the annular plug-in plate 503, so that the annular plug-in plate 503 can be reset with the assistance of the second reset spring 5023. When the annular plug-in plate 503 is reset, the circular movable plate 3028 will continue to pull the conical plate 504 to move upward until the conical plate 504 and the second rectangular notch 5031 at the annular plug-in plate 503 are located at the same horizontal plane. At this time, the quartz sand placed above the conical plate 504 can be returned from the inclined surface and the second rectangular notch 5031 to the top of the annular placement plate 501, thereby realizing the transposition of the quartz sand, so that it can be better preheated by the heating box 301. Step 5: When the driving gear 2012 rotates, it will be able to drive the worm 202 set at the bottom to rotate, and when the worm 202 rotates, it will be able to drive the worm wheel 2021 to rotate. Because the worm 202 and the worm wheel 2021 have a deceleration effect, and the reduction ratio is 1:20, so when the worm wheel 2021 rotates, the rotating rod 2022 can be rotated, and when the rotating rod 2022 rotates, it will be able to drive the cam 2023 to rotate, so that after the cam 2023 rotates a certain angle, it can squeeze the guide plate 401 to move vertically downward with the assistance of the second sliding mechanism.
