[0041] Working principle: first, the quartz tube body 31 is fixed on the fixed plate two 24, the spring sheet 25 and the clamping plate 26 of the clamping assembly firmly clamp the quartz tube, ensure its stability in the rotating process. After the motor 3 starts, the driving rod 4 drives the driving wheel 5 to rotate, the power transmission system of the belt 7 transmits power to the driven wheel 9, so that the rotating disc 8 and the clamping assembly drive the quartz tube to rotate. In the rotating process, the vacuum pump 21 extracts the air in the quartz tube through the sealing connection, forms a vacuum environment.

[0042] At the same time, the cleaning mechanism starts to work. The motor 3 drives the driving bevel gear 10 to rotate through the driving rod 4, and after engaging with the driven bevel gear 11, the movement of the driven rod 12, the eccentric wheel 13 and the rotating plate 14 is driven. The eccentric movement of the eccentric wheel 13 drives the sliding plate 15 and the brush plate 16 to clean inside the collecting box 19, ensuring that the debris generated in the process of quartz tube processing is effectively cleaned.

[0043] At the same time of the rotation of the quartz tube and the formation of the vacuum, the flame gun 30 obtains gas from the gas storage tank 28 through the pipeline 29, and the nozzle sprays uniform flame to heat and seal the quartz tube. The gas regulating valve controls the size and stability of the flame, ensuring the accuracy and efficiency of the sealing process.

[0044] During the whole process, the precise cooperation of the limiting rod 22 and the sliding block 23 ensures the stability of the fixed plate two 24, preventing the position deviation in the operation process. After the processing is completed, the quartz tube is pushed into the collecting box 19 by the sliding plate, completing the whole sealing and cleaning process.
