[0026] See also Figure 1-Figure 2As shown, the batching device for quartz crucible processing described in this embodiment includes a fixed frame 1, an automatic metering mechanism 2, a chute structure 3 and an aggregate structure 4. The automatic metering mechanism 2 is provided in plurality, and the plurality of automatic metering mechanisms 2 are respectively installed on the fixed frame 1. The chute structure 3 is fixedly arranged on the fixed frame 1, and the top of the chute structure 3 is respectively connected to the bottom ends of the plurality of automatic metering mechanisms 2. The aggregate structure 4 is located directly below the bottom end of the chute structure 3 and is used to hold materials.

[0027] This embodiment has a simple structure and a reasonable design. It uses multiple automatic metering mechanisms 2 to perform material measurement and weighing to achieve an accurate weight ratio. The weighed components enter the aggregate structure 4 through the chute structure 3 to complete the batching, thereby improving the batching efficiency and the crucible yield.

[0028] Specifically, the automatic metering mechanism 2 is provided with a barrel 21, a spiral arch breaking structure 22 and a weighing structure 23. The bottom end of the barrel 21 is provided with a discharge box 24 and a discharge pipe 25. A plug-in valve 26 is installed on the discharge pipe 25. The spiral arch breaking structure 22 is arranged in the barrel 21 for discharging materials into the discharge box 24. The weighing structure 23 is arranged at the bottom end of the discharge pipe 25.

[0029] Specifically, a feeding port 27 is provided at the top of the barrel 21 , and a material level meter 28 is installed.

[0030] In this embodiment, the setting of the automatic metering mechanism 2 is specifically shown. Weighing is performed by a weighing structure 23, which can specifically be a pressure sensor weighing device. The weighing and unloading process can ensure that the unloading process is uniform and stable through the spiral arch breaking scraper of the spiral arch breaking structure 22. At the same time, the frequency conversion motor is used to change the rotation speed of the spiral arch breaking scraper to ensure that the unloading accurately reaches the set value. When the unloading amount reaches the set weight, the gate valve 26 can be closed in time to realize the quantitative and automatic metering of the material; and the feeding port 27 arranged at the top of the barrel 21 is convenient for regular addition of materials, and the material level meter 28 therein is convenient for monitoring the material level so as to replenish the material in time.

[0031] In some embodiments, the chute structure 3 is installed at an inclined angle.

[0032] Specifically, a micro-rapping motor 31 is installed at the bottom end of the chute structure 3 .

[0033] In this embodiment, the chute structure 3 is installed at an inclined angle and a micro-rapping motor 31 is provided at the bottom end, so that the material discharge can be smooth.

[0034] In some embodiments, a fixing plate 11 is provided at the bottom end of the fixing frame 1 , a fixing groove 12 is provided on the fixing plate 11 , and a weighing pressure sensor 13 is provided in the fixing groove 12 , and the aggregate structure 4 is placed in the fixing groove 12 .

[0035] Specifically, the aggregate structure 4 is configured as an aggregate cylinder 21 .

[0036] In this embodiment, by setting up a fixed groove 12 for placing the collecting barrel 21, the position of the collecting barrel 21 can be prevented from changing during the batching process, which may cause the material to spill and affect the accuracy of the batching. At the same time, by providing a weighing pressure sensor 13 in the fixed groove 12, the prepared quartz sand material can be weighed and calibrated again. If there is a deviation from the preset value, the automatic metering mechanism 2 at the front end is promptly inspected and maintained to ensure the accuracy of the batching.

[0037] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
