[0035] Embodiment three:

[0036] On the basis of embodiments one and two, the preferred embodiment of the quartz crucible production accompanying conveying device provided by the utility model like Figures 1-4As shown: positioning component 42 includes: fixed vertical plate 421, symmetrically fixedly installed on the top of the traveling base plate 411; the inside of the fixed vertical plate 421 is sleeved with a short rod 422, one end of the short rod 422 is fixedly installed with a connecting block two 423, the outer side of the connecting block two 423 is symmetrically fixedly installed with a guide short rod 424, the other end of the guide short rod 424 is movably penetrated through the inner side of the fixed vertical plate 421 and extends to the outer side of the fixed vertical plate 421, and is fixedly installed with a limiting square plate 425, the limiting square plate 425 is fixedly connected with the short rod 422, the outer wall of the short rod 422 is sleeved with a spring 426, one end of the spring 426 is fixedly connected with the fixed vertical plate 421, the other end of the spring 426 is fixedly connected with the limiting square plate 425, the opposite side of the connecting block two 423 is fixedly installed with an arc-shaped positioning plate 427, the other side of the arc-shaped positioning plate 427 is fixedly installed with a rubber pad two 428.

[0037] Further, in the embodiment, by placing the quartz crucible 5 on the traveling base plate 411, the protective pad 412 plays a buffering and protection role, at this time, the quartz crucible 5 will contact the arc-shaped positioning plate 427 and push the short rod 422 to slide in the fixed vertical plate 421, the spring 426 is compressed, under the elastic force of the spring 426, the arc-shaped positioning plate 427 will exert a counter force on the quartz crucible 5, so that the quartz crucible 5 is positioned at a suitable position in the height direction, and the rubber pad two 428 also plays a protection role and preliminarily positions the quartz crucible 5.

[0038] In use, first, the quartz crucible 5 is placed on the traveling base plate 411, and the protective pad 412 serves as a buffer and protection. At this time, the quartz crucible 5 will come into contact with the arc-shaped positioning plate 427 and push the short rod 422 to slide in the fixed vertical plate 421. The spring 426 is compressed, and under the elastic force of the spring 426, the arc-shaped positioning plate 427 will exert a counterforce on the quartz crucible 5, positioning the quartz crucible 5 in the appropriate position in the height direction. The rubber pad two 428 also serves as a protective function and preliminarily positions the quartz crucible 5. After positioning is completed, the motor 414 is started, and the motor 414 drives the threaded rod 415 to rotate. Since the threaded rod 415 is threadedly connected with the connecting sleeve ring 416, the connecting sleeve ring 416 will move up and down along the threaded rod 415.

The motor one 8 is started, and its output end drives the shaft 6 connected thereto to rotate. Since the other end of the shaft 6 is fixedly sleeved with the belt pulley 10, and the belt pulleys 10 are transmissionally connected through the belt 11, the other shafts 6 will also rotate synchronously. The conveying roller 7 fixedly sleeved on the outer wall of the shaft 6 rotates, thereby driving the transmission plate chain 9 to start running, achieving conveying of the quartz crucible 5 and other materials placed on the transmission plate chain 9. When it is necessary to adjust the lateral position of the quartz crucible during conveying, the motor two 311 is started to drive the bidirectional threaded rod 312 to rotate. Since the outer wall of the bidirectional threaded rod 312 is symmetrically and threadedly connected with the movable block one 314, under the guiding action of the guide long rod 313 on the movable block two 315, the movable block one 314 and the movable block two 315 will move towards or away from each other. The vertical plate 317, the cross bar 318, the connecting base plate 319, the L-shaped connecting rod 3111, and the limiting plate 3112 connected through the connecting block one 316 will also move, thereby enabling left and right limiting and position adjustment of the quartz crucible on the transmission plate chain 9, ensuring that the quartz crucible remains in the appropriate lateral position during conveying, avoiding deviation or collision.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
