[0002] Quartz tube butt sealing is an important step in the processing and packaging of quartz tubes. Its purpose is to ensure that the butt joints of the quartz tubes achieve a good sealing effect.

The support rollers 601 on both sides are used to support the quartz tube. The corresponding rolling motor 602 is turned on, and the output end of the rolling motor 602 can drive the corresponding support roller 601 to rotate, so that the rotating support roller 601 can drive the supported quartz tube to rotate.

The output ends of the two electric push rods 801 are arranged on the two connecting plates 802 respectively, and a guide component is arranged on the base 1 for limiting the moving direction of the adjustment seat 5 and the U-shaped bracket 8. Opening the electric push rods 801 on both sides can push the connecting plate 802 to move. When the connecting plate 802 moves, it can adjust the distance between the adjustment seat 5 and the fixed seat 4, thereby driving the quartz tube on the adjustment seat 5 to align with the quartz tube on the fixed seat 4.

[0063] Example 2:

[0064] On the basis of Example 1, in order to enable the device to adapt to the butt welding and sealing processing of quartz tubes of different sizes, positioning structures for positioning the quartz tubes are arranged on the fixing seat 4 and the adjusting seat 5.

[0065] Among them, the positioning structure includes eight L-shaped adjustment frames 7 symmetrically rotatably mounted on the inner walls of the fixed seat 4 and the adjusting seat 5, and the same positioning roller 701 is rotatably mounted on the two L-shaped adjustment frames 7 on the same side. Eight rotating shafts 702 are symmetrically arranged on the inner walls of the fixed seat 4 and the adjusting seat 5 for providing rotation fulcrums for the L-shaped adjustment frames 7. The eight L-shaped adjustment frames 7 are rotatably mounted on the eight rotating shafts 702, and a linkage component arranged on the fixed seat 4 and the adjusting seat 5 for adjusting the position of the positioning roller 701 is used. Turning on the two positioning motors 707 drives the two threaded slides 703 away from each other. The two threaded slides 703 moving away from each other can cause the L-shaped adjustment frame 7 to flip over. The flipped L-shaped adjustment frame 7 can rotate with the rotating shaft 702 as the fulcrum, so that the flipped L-shaped adjustment frame 7 drives the positioning roller 701 to approach the quartz tube, and finally makes the positioning rollers 701 on both sides rest against the quartz tube to position the quartz tube.

[0066] Among them, the linkage assembly includes four threaded slides 703 symmetrically slidably mounted on the inner walls of the fixed seat 4 and the adjusting seat 5, eight linkage shafts 704 symmetrically arranged on both sides of the four threaded slides 703, eight linkage holes 705 respectively opened on the eight L-shaped adjustment frames 7, the eight linkage shafts 704 are movably mounted in the eight linkage holes 705, and two positive and negative threaded rods 706 respectively rotatably mounted on the fixed seat 4 and the adjusting seat 5, the two threaded slides 703 on the same side are threadedly mounted on the same positive and negative threaded rod 706, two positioning motors 707 respectively arranged on one side of the fixed seat 4 and the adjusting seat 5, the output ends of the two positioning motors 707 are respectively fixedly mounted on one end of the two positive and negative threaded rods 706, and are respectively opened on the fixed seat 4 and the adjusting seat 5. The two guide sliding holes 708 on the inner wall of the screw are used to guide the moving direction of the threaded slide 703. The two threaded slides 703 located on the same side are slidably installed in the same guide sliding hole 708. The rotating positive and negative screw rods 706 can drive the two threaded slides 703 to move away from each other by cooperating with the threads of the two threaded slides 703. The two threaded slides 703 moving away from each other can slide in the guide sliding holes 708, thereby preventing the threaded slides 703 from deviating. The continuously moving threaded slide 703 can drive the linkage shafts 704 on both sides to move in the corresponding linkage holes 705. At the same time, the linkage shaft 704 will squeeze the L-shaped adjustment frame 7 through the linkage hole 705, causing the L-shaped adjustment frame 7 to flip over. The flipped L-shaped adjustment frame 7 can rotate with the rotating shaft 702 as the fulcrum.

[0067] Working principle: Place the quartz tubes to be docked on the support rollers 601 of the fixing seat 4 and the adjusting seat 5 respectively, use the support rollers 601 on both sides to support the quartz tube, and at the same time place one end of the quartz tube against the positioning frame 9, and then turn on the two positioning motors 707. The output end of the positioning motor 707 can drive the positive and negative thread screws 706 to rotate. The rotating positive and negative thread screws 706 can drive the two thread slides 703 to move away from each other by cooperating with the threads of the two thread slides 703. The two thread slides 703 moving away from each other can slide in the guide slide hole 708, thereby avoiding the thread slide 703 from deflecting. The continuously moving thread slide 703 can The linkage shafts 704 on both sides can be driven to move in the corresponding linkage holes 705. At the same time, the linkage shafts 704 will squeeze the L-shaped adjustment frame 7 through the linkage holes 705 to flip the L-shaped adjustment frame 7. The flipped L-shaped adjustment frame 7 can rotate with the rotating shaft 702 as the fulcrum, so that the flipped L-shaped adjustment frame 7 drives the positioning roller 701 to approach the quartz tube, and finally makes the positioning rollers 701 on both sides rest on the quartz tube to position the quartz tube. Then, the electric push rods 801 on both sides are turned on, and the output end of the electric push rod 801 can push the connecting plate 802 to move. When the connecting plate 802 moves, it can drive the adjustment seat 5 to slide on the two guide slides 803, so that The distance between the adjusting seat 5 and the fixing seat 4 can be adjusted, thereby driving the quartz tube on the adjusting seat 5 to align with the quartz tube on the fixing seat 4. During the process, the U-shaped bracket 8 can be pushed to adjust the position of the first sealing nozzle 2, so that the first sealing nozzle 2 is aligned with the joint of the quartz tubes on both sides, and at the same time, the sliding rod 902 is pushed. The sliding rod 902 can slide on the adjusting slider 901 and drive the second sealing nozzle 3 to move, so that the second sealing nozzle 3 extends into the quartz tube and aligns with the joint of the inner walls of the quartz tubes on both sides. By rotating the lifting screw rod 903, it can be rotated in the lifting screw hole 904 and moved vertically, and then the lifting screw rod 903 can be rotated on the adjusting slider 901 and drive The slider 901 can be adjusted to rise and fall, and then the height of the sliding rod 902 and the second sealing nozzle 3 can be adjusted, so that the second sealing nozzle 3 can be close to the joint of the inner wall of the quartz tube so as to be adjusted according to the size of the quartz tube. When docking, the corresponding rolling motor 602 can be turned on, and the output end of the rolling motor 602 can drive the corresponding supporting roller 601 to rotate, so that the rotating supporting roller 601 can drive the supported quartz tube to rotate. During the process, the positioning roller 701 can rotate with the quartz tube. The first sealing nozzle 2 and the two second sealing nozzles 3 can be connected to the sealing equipment to spray flames at the joints of the rotating quartz tubes on both sides to seal the quartz tubes.
