Wherein, the unwinding roller 36, the winding roller 37 and the grinding roller 39 can rotate relative to the connecting plate 32.

Referring to fig. 1 again, in the present embodiment, the carrier plate 31 is substantially a plate-shaped structure, and the sliding direction of the carrier 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 slidably connected with the guide groove 311, so that the sliding of the bearing plate 31 is guided.

The connecting plate 32 is of a flat plate-shaped structure, the connecting plate 32 and the bearing plate 31 are perpendicular to each other, the guide rods 33 are of a rod-shaped structure, the guide rods 33 and the connecting plate 32 are perpendicular to each other, the number of the guide rods 33 is two, and the polishing frame 34 is slidably sleeved outside the guide rods 33, so that the reciprocating sliding direction of the polishing frame 34 can be the same as that of the sliding plate 20. The grinding frame 34 is effectively prevented from rotating relative to the guide rods 33 by the two guide rods 33. In other embodiments, not shown, the number of the guide rods 33 may be only one, and in this case, the cross section of the guide rods 33 is non-circular, so that the grinding frame 34 is prevented from rotating relative to the guide rods 33.

In addition, the bearing plate 31 is also 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 fixing plate 312 is arranged, so that the structural strength of the guide rod 33 is enhanced, and the guide rod 33 can be effectively prevented from being bent.

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

Referring to fig. 4 and 6, the unwinding roller 36 is rotatably disposed behind and below the grinding roller 39, and the winding roller 37 is rotatably disposed behind and above the grinding roller 39 (for clarity of illustration of the positional relationship of the components, it is provided that the carrier 200 is disposed in front of the grinding device 100). When the winding roller 37 rotates to wind, the unwinding roller 36 rotates under the driving of the polishing belt 381 to further rotate the polishing roll 38 to unwind, the polishing belt 381 is always in a tight state and tightly extruded on the polishing roller 39 in the winding and unwinding processes of the polishing belt 381, so that when the polishing roller 39 reciprocates left and right under the driving action of the connecting rod 353, the polishing belt 381 abutting against the polishing roller 39 can be driven to reciprocate together to further rapidly polish part of the outer peripheral surface of the guide roller in a reciprocating mode. In this embodiment, in order to increase the friction between the grinding roller 39 and the polishing strip 381 and ensure that the polishing strip 381 at the grinding roller 39 can move together with the grinding roller 39, an anti-slip part (not shown) is provided on the outer circumferential surface of the grinding roller 39, and the anti-slip part includes, but is not limited to, a protrusion, a groove or a knurl. 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, the unused part of the polishing belt 381 is gradually unwound, the peripheral surface of the guide roller is always in contact with the unused polishing belt 381, and the polishing quality is further guaranteed. In this embodiment, the sanding belt 381 is a sanding belt.

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

In a specific embodiment, the connection plate 32 is provided with a winding motor 321, an output shaft of the winding motor 321 is connected with the winding roller 37, and when the winding motor 321 is started, the winding roller 37 can be driven to rotate so as to realize an automatic winding function.

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

Referring to fig. 1 and 2 again, the carrying device 200 includes two opposite frame plates 41 and a carrying motor 42 connected to one of the frame plates 41, the two frame plates 41 are correspondingly provided with mounting holes 411, 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 to an output shaft of the carrying motor 42, so that the carrying motor 42 drives the guide roller to rotate.

In a specific embodiment, a water spray elbow 322 is connected to the connection plate 32, a water inlet of the water spray elbow 322 is communicated with a cooling water tank (not shown), and a water outlet of the water spray elbow 322 is located above the polishing roller 39, so that during polishing, the water spray elbow 322 can spray cooling liquid to the polishing position of the polishing roller 39 to achieve the purpose of cooling and ensure normal operation of each component.

The following describes the use process of the guide roller automatic grinding device of the invention with reference to the attached drawings:

the guide roller to be polished is installed on the bearing device 200 and rotates under the action of the bearing motor 42, the peripheral surface of the guide roller is tightly attached to the polishing belt 381, the polishing frame 34 reciprocates along the guide rod 33 under the drive of the drive assembly 35 so as to polish the peripheral surface of the guide roller, the screw rod 11 rotates slowly under the action of the rotating motor 12, the sliding plate 20 and the bearing plate 31 are driven to move slowly, 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 polishing of the guide roller is completed.
