Example Embodiment

[0013] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0014] See figure 1 As shown, the crucible lifting and rotating serial weighing device for the Ezoli sulfur analyzer of the present invention includes an L-shaped frame 1, a crucible lifting module and a crucible rotating module installed on the L-shaped frame 1, and The balance 7, weighing rod 8 and weighing pan 9 on the balance frame 2.
[0015] See figure 1 As shown, the crucible lifting module includes a first motor frame 36, an upper frame 35, a guide rail 31, and a lower frame 30 mounted on the L-shaped frame 1 from top to bottom, a nut 33 mounted on the screw 34, and The slider 32 on the guide rail 31; the first motor 37 is installed on the first motor frame 36, and the output shaft of the first motor 37 is connected to the upper end of the screw 34 through the coupling 4; the two ends of the screw 34 pass through The two bearings 5 ​​are installed on the upper bracket 35 and the lower bracket 30; the lifting plate 62 is installed on the nut 33 and connected with the slider 32.
[0016] See figure 1 As shown, the crucible rotating module includes a U-shaped frame 63 and a second motor frame 61 respectively installed on the upper and bottom of the lifting plate 62, through the bearing 5 installed on the U-shaped frame 63, and installed on the lifting plate 62 The other bearing 5 has a rotating shaft 64 connected to the output shaft of the second motor 60 mounted on the second motor frame 61 at its lower end, and a turntable 65 mounted on the rotating shaft 64; the turntable 65 is provided with four axisymmetrically distributed Crucible hole 651, the crucible 10 containing the experimental product 11 is placed in the crucible hole 651; the lower end of the weighing rod 8 is installed on the balance 7, and the upper end of the weighing pan 9 is installed; the axis of the weighing rod 8 is The axes of a crucible hole 651 coincide.
[0017] Working principle: The second motor 60 rotates, driving the shaft 64 and the turntable 65 to rotate, and then driving the crucible 10 to rotate, so that the crucible 10 to be weighed is aligned up and down with the weighing plate 9; the first motor 37 rotates, the lead screw 34 rotates, and drives The lifting plate 62 and the turntable 65 rise or fall synchronously; after the turntable 65 descends, the crucible 10 is lifted by the weighing pan 9 and leaves the turntable 65, and the balance 7 starts to weigh the crucible 10.
