Referring to FIG. 1 at the same time, the driving wheel 321 is generally arranged at the included angle where the second vertical section and the second horizontal section intersect, the first driven wheel 323 is arranged on the second horizontal section close to one end of the transition roller 10, The two driven wheels 325 are disposed on one end of the second vertical section close to the base plate 311 . The driving wheel 321 , the first driven wheel 323 and the second driven wheel 325 are all located on the same side of the second polishing frame 315 , and the power source 330 is located on the other side of the second polishing frame 315 . In this embodiment, the first driven wheel 323 and the second driven wheel 315 have the same structure. The first driven wheel 323 and the second driven wheel 325 are respectively connected to the second polishing frame 315 through their corresponding support shafts 302 . The support shaft 302 can be regarded as a fixed end portion of the first driven wheel 323 to support the first driven wheel 323 and enable the first driven wheel 323 to rotate around its axis.

The first horizontal plate and the first vertical section of the first polishing frame 313 are integrally formed, and the second vertical section and the second horizontal section of the second polishing frame 315 are integrally formed, but are not limited to integral formation.

Referring to FIG. 2 , the end of the second horizontal section of the second polishing frame 315 close to the transition roller 10 is provided with a notch 312 , and the notch 312 is configured to extend from the surface of the second horizontal section opposite to the transition roll 10 to the second vertical The direction of the straight section is concave and formed. That is to say, the portion of the second polishing frame 315 corresponding to the first driven wheel 323 is set as the notch 312 . Correspondingly, a top rod 314 and a telescopic rod 316 are provided on the second horizontal section, and the telescopic rods 316 of the top rod 314 are both located on the same side of the second horizontal section and opposite to the polishing wheel 320 . One end of the telescopic rod 316 is fixedly connected to the second horizontal section, and the other end is connected to the fixed end of the first driven wheel 323 . In the horizontal direction, that is, in the moving direction of the polishing mechanism 300 , the top rod 314 is located between the first driven wheel 323 and the telescopic rod 316 .

Referring to FIG. 2 , the telescopic rod 316 is arranged horizontally, and includes a fixed section 303 and a movable section 305 . The fixed section 303 is fixed on the second horizontal section, one end of the movable section 305 is inserted into the fixed section 303 and can move back and forth linearly relative to the fixed section 303, and the other end of the movable section 305 is connected to the fixed end portion of the first driven wheel 323 . In this embodiment, at a position corresponding to the movable segment 305 , a support block 304 is further provided on the fixed end portion of the first driven wheel 323 , and the other end of the movable segment 305 is connected to the support block 304 . One end of the support shaft 302 corresponding to the first driven wheel 323 away from the first driven wheel 323 is connected to the support block 304 through the gap 312 . That is to say, the support block 304 and the first driven wheel 323 are respectively located on two sides of the second polishing frame 315 and correspond to the notches 312 . It should be noted that the telescopic rod 316 is provided with a self-locking structure, and the self-locking structure can make the movable section 305 extend from the fixed section 303 to the set position without retracting to the fixed section 303 under the action of abnormal external force. The specific setting of the self-locking structure is suitable to achieve the above purpose.

Since the first driven wheel 323 is connected to the movable section 305 , the movable section 305 can be close to or away from the fixed section 303 , so that the first driven wheel 323 can be close to or away from the position where the transition roller 10 is provided, wherein the gap 312 provides movement for the support shaft 302 space. That is, in this embodiment, both the driving wheel 321 and the second driven wheel 325 are fixed relative to the second polishing frame 315 , and the first driven wheel 323 is movable relative to the second polishing frame 315 . With the above arrangement, before installing the transition roller 10 to the bracket 100 , the movable segment 305 can be retracted to the fixed segment 303 to move the position of the first driven wheel 323 without interfering with the installation of the transition roller 10 . After the transition roller 10 is installed to the bracket 100 , the movable section 305 can be pulled out from the fixed section 303 to move the first driven wheel 323 to a corresponding station.

Referring to FIG. 2 , the top rod 314 has a substantially rectangular parallelepiped structure. One of the two opposite sides on the top rod 314 is opposite to the side of the support block 304 . When the movable section 305 in the telescopic rod 316 is not retracted relative to the fixed section 303 , the top rod 314 is rotated to make surface contact with the support block 304 . At this time, the top rod 314 is inclined in the vertical plane, and there is a force on the support block 304, which can make the first driven wheel 323 away from the driving wheel 321 and the second driven wheel 325 (not shown in FIG. 2 ), so as to be tensioned The polishing belt 301 is wound around the polishing wheel 320 .

More specifically, teeth are provided on the circumferential direction of the rotating shaft, and teeth are provided on the motion converting member 343 in meshing connection with the rotating shaft. When the driving member 341 drives the rotating shaft to rotate, the motion converting member 343 converts the rotary motion of the rotating shaft into linear motion, so that the polishing mechanism 300 realizes linear displacement. The motion converting member 343 may adopt a rack structure. The driving member 341 may be a motor.

Compared with other ways of driving the polishing frame 310 to move, the polishing mechanism 300 is driven to move by the rotating shaft of the driving member 341 engaging with the motion converting member 343 to drive. The motion of the polishing frame 310 is highly stable and the speed is adjustable.
