Description

Technical Field

[0001] This utility model relates to the field of quartz crucible production technology, specifically to a quartz crucible raw material feeding and forming device. Background Technology

[0002] The production process of quartz crucible blanks involves loading high-purity quartz powder into a rotating mold that can be tilted at any angle. Using centrifugal force and manual shaping with a forming rod, the already crucible-shaped rotating device is rotated back to the electrode rod. Then, the electrode is arc-shaped and inserted into the already formed powder cavity, where it is used to quickly melt molten quartz into a crucible shape. After cooling, it is removed, thus completing the production of a quartz crucible blank.

[0003] Quartz crucibles have a multi-layered composite structure. As product quality specifications become increasingly stringent, the material layer structure of quartz crucibles is also becoming more complex. Each layer of the quartz crucible needs to be filled with different types of quartz material. The current feeding process is manual. Due to the long feeding distance and numerous feedings, the labor intensity of the operators is extremely high. Some employees will open the lid of the raw material bucket to feed directly in order to save time, which makes it impossible to effectively control the uniform discharge speed. Moreover, after feeding, manual molding is required to assist in molding, resulting in an uncontrollable material layer structure. Utility Model Content

[0015] like Figure 1-3As shown, the quartz crucible raw material feeding and forming device includes a cylinder 1, a robotic arm 3, and a forming rod 9. A feed inlet 2 is provided on the top end face of the cylinder 1. One end of the cylinder 1 is fixedly connected to the robotic arm 3, and the other end of the cylinder 1 is fixed and connected to a conical guide tube 4. An elbow 5 is fixed at the end of the conical guide tube 4 away from the cylinder 1, and a discharge port 6 is provided at the end of the elbow 5. The robotic arm 3 is used to extend the cylinder 1 into the rotary molding mold. The three-dimensional movement trajectory of the robotic arm 3 is set to adapt to the size of different quartz crucibles. The control of the robotic arm 3 is a conventional design in this field and will not be described in detail in this embodiment. The discharge position of the raw material is controlled according to the different models of quartz crucibles. Then, the feed inlet 2 of the cylinder 1 is connected to a feeding device. Specifically, the raw material in the raw material bin is transported into the cylinder 1 by pneumatic conveying, and then sequentially delivered to the conical guide tube 4, elbow 5, and discharge port 6 under the action of gravity.

[0016] Furthermore, a first support rod 7 is fixed to the outer wall of the elbow 5, and a second support rod 8 is fixed to the outer wall of the cylinder 1. A forming rod 9 is fixed between the first support rod 7 and the second support rod 8. The forming rod 9 is arranged parallel to the axis of the cylinder 1. When the raw material is put into the rotary forming mold, the forming rod 9 spreads the raw material evenly during the rotation of the rotary forming mold, reducing the amount of manual forming labor.

[0017] Furthermore, the discharge port 6 is provided with a discharge chute 10, which is fixedly connected to the outer wall of the elbow 5. The discharge chute 10 can be used to achieve uniform material discharge and reduce local accumulation of materials.

[0018] Furthermore, the discharge port 6 is equipped with a flap valve 11. In this embodiment, the flap valve 11 is a pneumatic flap valve. The auxiliary equipment includes an actuator. A purging nozzle 12 is provided above the discharge chute 10. In this embodiment, the purging nozzle 12 is fixed to the outer wall of the actuator of the flap valve 11. The purging nozzle 12 is connected to the compressed air pipe 13. After feeding is completed or before feeding, the discharge port 6 is closed by using the flap valve 11. The high-pressure clean airflow purifies the discharge port 6 and the discharge chute 10 to remove residual quartz dust or environmental dust and avoid cross-contamination.

[0019] Furthermore, a liner plate 14 is fixed to the inner wall of the cylinder 1 to reduce the contamination of the raw materials by the material of the cylinder 1.

[0020] Furthermore, an electromagnetic vibrator 15 is fixed to the outer wall of the conical guide tube 4. The electromagnetic vibrator 15 breaks the bridging effect between quartz sand particles through high-frequency micro-vibration (frequency adjustable range 50-200Hz) to ensure uniform flow.

[0021] The specific operation process of this embodiment is as follows: The robotic arm 3 is used to extend the cylinder 1 into the rotary molding mold. The three-dimensional movement trajectory of the robotic arm 3 is set to adapt to the size of different quartz crucibles. The discharge position of the raw material is controlled according to the different models of quartz crucibles. Before use, close the discharge port 6 using the flap valve 11, and use high-pressure clean airflow to purge the discharge port 6 and the discharge chute 10 to remove residual quartz dust or environmental dust and avoid cross-contamination. The feed inlet 2 of the cylinder 1 is connected to the feeding device. The raw material in the raw material silo is transported to the inside of the cylinder 1 by pneumatic conveying. Then, under the action of gravity, it is sequentially sent to the conical guide cylinder 4, elbow 5, and discharge port 6. Under the action of the electromagnetic vibrator 15, the material is fed smoothly and evenly. The raw material is put into the rotary molding die. During the rotation of the rotary molding die, the forming rod 9 spreads the raw material evenly. After use, the discharge port 6 is closed by using the flap valve 11, and the high-pressure clean airflow is used to purge the discharge port 6 and the discharge chute 10 to remove residual quartz dust or environmental dust.
