Wherein the unreeling roller 36, the reeling roller 37 and the polishing roller 39 are rotatable relative to the connecting plate 32.

Referring to fig. 1 again, in the present embodiment, the carrying plate 31 has a substantially plate-shaped structure, and the sliding direction of the carrying plate 31 is perpendicular to the sliding direction of the sliding plate 20. The upper end surface of the sliding plate 20 is convexly provided with a guide strip 22, the lower end surface of the bearing plate 31 is provided with a guide groove 311, and the guide strip 22 is in sliding connection with the guide groove 311, so that the sliding of the bearing plate 31 is guided.

The connecting plate 32 is the dull and stereotyped structure, and connecting plate 32 and loading board 31 mutually perpendicular, and guide arm 33 is the rod-like structure, and guide arm 33 and connecting plate 32 mutually perpendicular set up, and guide arm 33 has two, and the frame 34 of polishing slidably overlaps the outside of establishing at guide arm 33 to make the reciprocal slip direction of frame 34 of polishing the same with the reciprocal slip direction of slide 20. By providing two guide rods 33, the grinding frame 34 can be effectively prevented from rotating relative to the guide rods 33. In other embodiments, not shown, only one guide bar 33 may be provided, and the cross section of the guide bar 33 is in a non-circular structure, so that the grinding frame 34 can be prevented from rotating relative to the guide bar 33.

In addition, the bearing plate 31 is fixedly provided with a fixing plate 312, the fixing plate 312 is parallel to the connecting plate 32, the guide rod 33 is fixedly connected between the fixing plate 312 and the connecting plate 32, and the structural strength of the guide rod 33 is enhanced by arranging the fixing plate 312, so that the guide rod 33 can be effectively prevented from bending.

In this embodiment, the polishing frame 34 includes two vertical plates 341 disposed parallel to each other and a cross bar 342 connected between the two vertical plates 341, the vertical plates 341 are slidably sleeved outside the guide bar 33, and the polishing roller 39 is rotatably installed between the two vertical plates 341.

In addition, in the polishing process, as the polishing belt 381 is continuously wound and unwound, the used part of the polishing belt 381 is gradually wound and the unused part of the polishing belt 381 is gradually unwound, so that the outer circumferential surface of the guide roller is always in contact with the unused polishing belt 381, and further the polishing quality is ensured. In this embodiment, the sanding belt 381 is a sanding belt.

In addition, in order to ensure that the sanding belt 381 is always in a stretched state during sanding, the joint between the unreeling roller 36 and the connecting plate 32 has a certain resistance, which can prevent the unreeling roller 36 from being easily rotated, for example, the aperture of a mounting hole for mounting the unreeling roller 36 on the connecting plate 32 can be reduced, so that when the unreeling roller 36 is mounted in the mounting hole, a large force needs to be applied to rotate the unreeling roller 36.

In a specific embodiment, the winding motor 321 is installed on the connecting plate 32, an output shaft of the winding motor 321 is connected with the winding roller 37, and the winding motor 321 can drive the winding roller 37 to rotate when being started so as to realize automatic winding.

In addition, referring to fig. 6 again, the connecting plate 32 is further rotatably provided with a tensioning roller 40, the tensioning roller 40 is located between the polishing roller 39 and the wind-up roller 37, and the tensioning roller 40 is located above the wind-up roller 37, and when in use, the polishing belt 381 winds around the tensioning roller 40 and then winds around the wind-up roller 37, so as to play a role in tensioning, and further ensure that the polishing belt 381 is in a tensioned state.

Referring to fig. 1 and 2 again, the bearing device 200 includes two opposite frame plates 41 and a bearing motor 42 connected to one of the frame plates 41, where the two frame plates 41 are correspondingly provided with mounting holes 411, and when in use, two ends of a guide roller to be polished are respectively mounted in the two mounting holes 411, and one end of the guide roller is connected with an output shaft of the bearing motor 42, so that the bearing motor 42 drives the guide roller to rotate.

In a specific embodiment, the connecting plate 32 is connected with a water spraying elbow pipe 322, a water inlet of the water spraying elbow pipe 322 is communicated with a cooling water tank (not shown), and a water outlet of the water spraying elbow pipe 322 is positioned above the polishing roller 39, so that when polishing, the water spraying elbow pipe 322 can spray cooling liquid to the polishing position of the polishing roller 39 to achieve the purpose of cooling and ensure that all parts work normally.

The following describes the use process of the automatic guide roller polishing equipment according to the invention with reference to the accompanying drawings:

The guide roller to be polished is arranged on the bearing device 200 and rotates under the action of the bearing motor 42, the outer peripheral surface of the guide roller is clung to the polishing belt 381, the polishing frame 34 is driven by the driving component 35 to reciprocate along the guide rod 33 so as to polish the outer peripheral surface of the guide roller, the screw rod 11 slowly rotates under the action of the rotating motor 12 so as to drive the sliding plate 20 and the bearing plate 31 to slowly move, the moving speed of the bearing plate 31 is far lower than that of the polishing roller 39, and when the bearing plate 31 is driven by the sliding plate 20 to move from one end of the guide roller to the other end, the guide roller polishing is completed.
