The angle is adjusted, which is convenient for cooperating with multiple groups of photoelectric sensors to continuously monitor the forming state of the quartz tube, so that the guide edge 3012 can be aligned with the position of the preset heat stress groove on the outer peripheral side of the quartz tube, and the heat stress groove opened on the outer peripheral side surface of the quartz tube is dynamically adjusted by using the guide edge 3012.That is, when the stretching control component 10 is used to stretch the quartz tube, if the molded quartz tube grows too much and causes subsequent deviation, the molding guide component 3 is adjusted and forms an alignment guide with the stretching control component 10, and then is stretched at a uniform speed. Then, the groove 3010 on the inner wall of the high-temperature resistant swivel 304 is adjusted to cooperate with the bottom plate 3014, the return damping spring 3013 and the guide edge 3012 to reinforce the thermal stress groove opened on the periphery of the above-mentioned quartz tube. At the same time, the guide edge 3012 is slidably connected with the thermal stress groove on the periphery of the quartz tube being molded to ensure the stability and shape accuracy of the quartz tube during the molding process. The formed quartz tube passes through the other end of the guide tube 303 and enters the quality inspection end 4 for subsequent quality inspection and processing. Thereafter, when the inspected quartz tube is stretched and guided to the position slotted cutting seat 6, it is in a preset cutting position. After that, the guide air rod 16 drives the positioning frame 18 to slide and adjust inside the rail groove frame 17. After the position information is positioned by using the position slot cutting seat 6 and the positioning frame 18, the micro-drilling structure 19 stops at the correct cutting position of the quartz tube. Then the micro-drilling structure 19 performs prestressed drilling on the cutting points of the quartz tube in turn. Then the electric lifting rod 14 drives the position laser cutting end 15 to descend above the quartz tube. The position laser cutting end 15 accurately cuts the quartz tube according to the preset length parameters to ensure that the length of each section of the quartz tube meets the standard. The cut quartz tube section automatically slides into the discharge guide groove 12 through the cooperation of the horizontal linear rail 7 and the longitudinal short linear rail 11 to complete the collection of the finished product. The above-mentioned stretching control component 10 with quality deviation drives the stretched and fixed quartz tube to be placed in the storage guide groove on the other side.
