(2) During the grinding process, the booster pump injects water into the multiple atomizing nozzles through the water inlet pipe. Water is evenly sprayed into the crucible through multiple atomizing nozzles, thereby preventing excessive wear of the grinding belt and making the inner wall of the crucible more delicate. The water pump absorbs the accumulated water in the crucible through the drainage pipe and the suction nozzle and discharges the accumulated water, so that water can be sprayed into the crucible while the accumulated water inside the crucible is discharged, realizing water circulation, making the inside of the crucible cleaner after grinding, avoiding the inconvenience of cleaning the crucible again after grinding; (3) By placing the quartz crucible on the top of the support table, through two cylinders The fixing plates are pushed to move respectively, and the two positioning plates are pushed to move by the fixing plates, and the outer wall of the quartz crucible is squeezed and fixed by the positioning plates respectively, and the outer wall of the quartz crucible is contacted by the rubber pads on the inner side of the positioning plates, thereby increasing the pressure of the positioning plates on the outer wall of the quartz crucible and improving the clamping force on the quartz crucible; (4) The winding shaft and the unwinding shaft are driven to rotate synchronously by the two second motors respectively, thereby driving the grinding belt to move, so that the grinding belt slides along the inner wall of the steel plate and the inner wall of the connecting plate, thereby replacing the excessively worn grinding belt.

[0031] Two suction nozzles 328 are fixedly connected to the end of the connecting pipe 301, and a drain pipe 303 is fixedly connected to the outer wall of the connecting pipe 301. One end of the drain pipe 303 is fixedly connected to the two suction nozzles 328, and the other end of the drain pipe 303 is fixedly connected to the water pump 105.

The ends of the water inlet pipe 304 are respectively fixedly connected to the plurality of atomizing nozzles 302, and the other end of the water inlet pipe 304 is fixedly connected to the booster pump 104, and the water inlet of the booster pump 104 is connected to the external water storage container.

[0032] The two ends of the steel plate 305 are respectively fixedly connected with connecting plates 306, and two extension plates 319 are fixedly connected to the top of the steel plate 305. The two extension plates 319 are respectively fixedly connected to the connecting plates 306.

In order to make the steel plate 305 bend when it is squeezed by the inner wall of the crucible, the yield strength of the steel plate 305 is set to be relatively low and the thickness is relatively small. The length setting of the steel plate 305 can ensure stress dispersion.

[0033] The hydraulic cylinder 108 pushes the connecting shaft 109 to slide along the installation box 101 toward the inside thereof, and the connecting shaft 109 drives the second cylindrical gear 110 to slide along the outer wall of the first cylindrical gear 107, and the connecting shaft 109 pushes the connecting pipe 301 to move downward, and the connecting pipe 301 pushes the steel plate 305 to move toward the inner wall of the quartz crucible. At this time, the steel plate 305 bends according to the shape of the inner wall of the quartz crucible. When the steel plate 305 bends, the second hinge seat 315 pushes the connecting rod 312 to slide toward the inner wall of the connecting sleeve 310. At this time, the connecting rod 312 passes through the second limit The ring 314 squeezes the spring 313, and the springs 313 on the multiple connecting rods 312 will shrink according to the shape of the inner wall of the quartz crucible. Under the elastic force of the multiple springs 313, the connecting rods 312 can squeeze the outer wall of the steel plate 305 in the opposite direction, so that the polishing belt 322 at the bottom of the steel plate 305 can fully fit with the inner wall of the quartz crucible. This design can be polished according to crucibles of different sizes, and at the same time, the polishing belt 322 can quickly and fully fit with the inner wall of the crucible, thereby improving the polishing effect and efficiency of quartz crucibles of different sizes.

[0034] During the grinding process, the booster pump 104 injects water into the multiple atomizing nozzles 302 through the water inlet pipe 304, and the water is evenly sprayed into the crucible through the multiple atomizing nozzles 302, thereby preventing the grinding belt 322 from being excessively worn, so that the inner wall of the crucible is ground more finely. The water pump 105 absorbs the accumulated water in the crucible through the drain pipe 303 and the suction nozzle 328, and discharges the accumulated water, so that water can be sprayed into the crucible while the accumulated water in the crucible is discharged, realizing water circulation, so that the inside of the crucible is cleaner after grinding, avoiding the inconvenience of cleaning the crucible again after grinding.

[0035] The working principle of the present invention is as follows.

[0036] By placing the quartz crucible on top of the support platform 102, the two cylinders 201 push the fixed plates 202 to move, and the fixed plates 202 push the two positioning plates 203 to move, the outer wall of the quartz crucible is squeezed and fixed by the positioning plates 203, and the rubber pads 204 on the inner side of the positioning plates 203 contact the outer wall of the quartz crucible, thereby increasing the pressure of the positioning plates 203 on the outer wall of the quartz crucible and improving the clamping force on the quartz crucible.

[0037] The hydraulic cylinder 108 pushes the connecting shaft 109 to slide along the installation box 101 toward the inside thereof, and the connecting shaft 109 drives the second cylindrical gear 110 to slide along the outer wall of the first cylindrical gear 107, and the connecting shaft 109 pushes the connecting pipe 301 to move downward, and the connecting pipe 301 pushes the steel plate 305 to move toward the inner wall of the quartz crucible. At this time, the steel plate 305 is bent according to the shape of the inner wall of the quartz crucible. When the steel plate 305 is bent, the second hinge seat 315 pushes the connecting rod 312 to slide toward the inner wall of the connecting sleeve 310. At this time, the connecting rod 312 squeezes the spring 313 through the second limiting ring 314, and the springs 313 on the multiple connecting rods 312 will shrink according to the shape of the inner wall of the quartz crucible. Under the elastic force of the multiple springs 313, the connecting rod 312 can squeeze the outer wall of the steel plate 305 in the opposite direction, so that the steel plate 305 can be fully fitted with the inner wall of the quartz crucible.

[0038] The support shaft 106 is driven to rotate by the first motor 111, the first cylindrical gear 107 is driven to rotate by the support shaft 106, the second cylindrical gear 110 is driven to rotate by the first cylindrical gear 107, the connecting shaft 109 is driven to rotate by the second cylindrical gear 110, the steel plate 305 is driven to rotate by the connecting shaft 109, and the steel plate 305 drives the grinding belt 322 to rotate, so that the inner wall of the quartz crucible can be effectively and quickly grinded. The first motor 111 rotates forward and reversely during operation to prevent the water inlet pipe 304 and the drain pipe 303 from being excessively wound around the connecting pipe 301, resulting in knots in the water inlet pipe 304 and the drain pipe 303.

[0039] During the grinding process, the booster pump 104 injects water into the multiple atomizing nozzles 302 through the water inlet pipe 304, and the water is evenly sprayed into the crucible through the multiple atomizing nozzles 302, thereby preventing the grinding belt 322 from being excessively worn, so that the inner wall of the crucible is ground more finely.

[0040] The water pump 105 absorbs the accumulated water in the crucible through the drain pipe 303 and the suction nozzle 328, and discharges the accumulated water, so that water can be sprayed into the crucible while the accumulated water in the crucible is discharged, realizing water circulation, making the inside of the crucible cleaner after grinding, avoiding the inconvenience of cleaning the crucible again after grinding.

[0041] The two second motors 327 drive the reel 326 and the unreel 324 to rotate synchronously, thereby driving the grinding belt 322 to move, so that the grinding belt 322 slides along the inner wall of the steel plate 305 and the inner wall of the connecting plate 306, so as to replace the excessively worn grinding belt 322.
