Description

Technical Field

[0001] The invention relates to the technical field of quartz crucibles, and more specifically to a feeding device for preparing quartz crucibles. Background Art

[0002] Quartz crucibles are mainly made of high-purity quartz materials. The preparation process usually includes raw material preparation, feeding, molding, sintering, cooling and other steps. Among them, feeding is a very important part of the preparation process of quartz crucibles. Many existing feeding steps are still completed manually, which requires a high level of worker proficiency and has high labor intensity.

[0003] Although some loading steps are completed by equipment, in the loading step, the mixed quartz material needs to be poured into the material holding barrel, and then the quartz material is loaded onto the mold through the loading device. When the existing loading device is used to prepare the quartz crucible, the raw materials are easily stuck inside the material holding barrel during the loading process, causing blockage or material jamming, which not only affects the normal loading of the material, but also affects the uniformity of the material loading, resulting in the loading device may not be able to ensure the uniform discharge of the material, resulting in uneven thickness of the material after it adheres to the side wall of the mold, resulting in unsatisfactory loading effect, affecting the production quality of the quartz crucible. In addition, in the preparation process of the quartz crucible, the quartz sand needs to be weighed. Only by accurate weighing can it be ensured that each quartz crucible product meets the production requirements, thereby ensuring the production of high-quality quartz crucible products. Summary of the invention

[0041] Working principle: The feeding device of the present application, the material barrel is used to hold quartz sand. By opening the first valve, the material in the material barrel can fall into the unloading barrel. By opening the second valve, the material can fall from the unloading barrel into the throwing unit. The material falling into the throwing unit is hit by the rotating blades, and the material is discharged from the discharge pipe and attached to the side wall of the mold. And the bottom shell can be rotated by the driving motor, so that the discharge angle can be adjusted. In addition, when the unloading barrel is unloading, the cam can hit the unloading barrel, thereby causing vibration, so that the material in the unloading barrel is unloaded more evenly, and there will be no jamming and failure to unload. During vibration, due to the connection of the spring, a certain buffer is provided to make the overall vibration effect better. And the weighing unit can weigh the material barrel, so that the weight of the used material can be obtained according to the weight difference, thereby achieving the purpose of metering. When loading materials, two unloading barrels can be selected according to different production scenarios. One unloading barrel is used to receive the materials dropped from the filling barrel (the second valve at the bottom of the unloading barrel is closed at this time), and the other unloading barrel is used to drop the internal materials into the material throwing unit (the first valve above the unloading barrel is closed at this time). After the materials in the unloading barrel have finished falling (a time for dropping can be set, and when the time is up (the materials in the unloading barrel are basically at the bottom, not necessarily completely emptied), switch to another unloading barrel for dropping), the unloading barrel is used to receive the materials from the filling barrel, and the other unloading barrel is used to drop the materials into the material throwing unit, and the execution is alternating. Therefore, for the material throwing unit, the dropping of materials is basically uniform, and the throwing of materials is also uniform, so as to achieve a better loading effect.

[0042] In other production scenarios, if the material throwing speed needs to be faster, two material discharge barrels can also drop materials into the material throwing unit at the same time, and the material holding barrel can drop materials into the two material discharge barrels at the same time, so that the overall material throwing speed is faster, which is suitable for large-sized crucible loading and molding.

[0043] In addition, when the lifting frame is raised or lowered, the hard tube part can be raised or lowered with the lifting frame, the position of the material barrel remains unchanged, and the bellows can be extended or retracted to cooperate with the two. The lower material barrel is hoisted on the feed plate through the flexible surrounding unit at the top, and the lower material barrel is not fixedly connected to the upper through hole and the lower through hole, thereby providing space for the shaking of the lower material barrel.

[0044] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
