[0074] Among them, the adjustment structure includes a threaded slide rod 6 slidably installed on the inner wall of the base 1, a plurality of linkage push rods 601 rotatably installed on one side of the threaded slide rod 6, two connecting plates 602 fixedly installed on one side of the two adjusting seats 3, the two connecting plates 602 are respectively rotatably installed on the two linkage push rods 601 on the same side, an adjusting screw rod 603 rotatably installed on the inner wall of the base 1, the threaded slide rod 6 is threadedly installed on the adjusting screw rod 603, and the threaded slide rod 6 can slide on the inner wall of the base 1 as the adjusting screw rod 603 rotates.

[0076] Among them, the guiding assembly includes four limiting chutes 605 respectively opened on the inner wall of the base 1, and four limiting sliders 606 symmetrically and fixedly installed on the bottom sides of the two adjusting seats 3 respectively.

During the movement of the adjusting seat 3, the limiting sliders 606 will be driven to slide in the corresponding limiting chutes 605, thereby restricting the moving direction of the adjusting seat 3.

[0077] Working principle:

[0078] When the adjustment motor 604 is turned on, the output end of the adjustment motor 604 can drive the adjustment lead screw 603 to rotate. The rotating adjustment lead screw 603 can drive the threaded slide bar 6 to slide on the inner wall of the base 1 through the threaded fit with the threaded slide bar 6. The sliding threaded slide bar 6 can drive one end of the two linkage push rods 601 to flip and move, so that the other ends of the two linkage push rods 601 drive the two connecting plates 602 to move towards or away from each other respectively. Furthermore, the moving connecting plates 602 drive the adjustment seat 3 to move. The continuously moving adjustment seat 3 can drive the bearing seat 301, the connecting shaft 302 and the supporting roller 303 to move, and thus the distance between the two supporting rollers 303 can be adjusted to be adjusted according to the size of the quartz drawing tube 2;

[0079] When the port of the quartz drawing tube 2 needs to be polished, the quartz drawing tube 2 can be placed on the two supporting rollers 303. The height of the mounting frame 4 can be adjusted by controlling the expansion and contraction of the output end of the electric push rod 401, driving the transmission grinding belt 411 to descend, so that the cutting port of the quartz drawing tube 2 contacts the transmission grinding belt 411 and the second positioning wheel 414. At the same time, it will drive the two adjusting rollers 405 to contact the top surface of the quartz drawing tube 2. At this time, the positioning motor 503 can be turned on. The output end of the positioning motor 503 can drive the screw rod 502 to rotate. The rotating screw rod 502 can drive the threaded slider 5 to slide in the guiding chute 501 through the threaded fit with the threaded slider 5. The sliding threaded slider 5 can drive the positioning seat 402 to move, so that the positioning seat 402 drives the first positioning frame 407 and the first positioning wheel 408 to move, and makes the first positioning wheel 408 contact the other end of the quartz drawing tube 2. Thus, the two ends of the quartz drawing tube 2 can be blocked and positioned by the first positioning wheel 408 and the second positioning wheel 414 to prevent the position of the quartz drawing tube 2 from shifting. When polishing, the grinding motor 412 can be turned on. The output end of the grinding motor 412 can drive the transmission roller 410 to rotate. Under the transmission cooperation of the two transmission rollers 410 and the transmission grinding belt 411, the two transmission rollers 410 can rotate simultaneously and drive the transmission grinding belt 411 to make a circular motion. The circular motion of the transmission grinding belt 411 generates friction with the cutting port of the quartz drawing tube 2 to polish the port. During the process, the two driving motors 406 on both sides can be turned on. The output end of the driving motor 406 can drive the adjusting roller 405 to rotate, so that the rotating adjusting roller 405 drives the quartz drawing tube 2 to rotate through the contact and friction with the surface of the quartz drawing tube 2. The rotating quartz drawing tube 2 will drive the supporting roller 303 to rotate, so as to adjust the position of the port of the quartz drawing tube 2, and make the transmission grinding belt 411 polish the port more comprehensively.
