At the same time, the grinding head driving member 31 of the grinding head assembly 30 rotates to drive the grinding head 36 to rotate. In this way, the grinding head 42 can grind the steel belt during rotation and reciprocating swing.

[0032] See also Figure 1 The first shielding plate 34, the second shielding plate 35 and the third shielding plate 67 can all be used to prevent the splashing of the grinding liquid during the grinding process of the grinding head 42. When the grinding head 42 stops grinding the steel belt, the second shielding plate 35 can be pulled up and swung upward.

[0033] In summary, the present invention drives the carrier frame 22 to swing through the swing drive mechanism 40, and then drives the grinding head 42 at the lower end of the carrier frame 22 to swing. The grinding head driving member 31 simultaneously drives the grinding head 42 to rotate during the swinging of the carrier frame 22. In this way, the grinding head 42 can not only grind the surface of the steel belt during rotation, but also repeatedly swing to other positions on the surface of the steel belt for repeated grinding. The grinding is more comprehensive and thorough, and the grinding quality is good.

[0034] The first baffle plate 34, the second baffle plate 35 and the third baffle plate 67 can effectively block the grinding liquid splashed when the grinding head 42 grinds the surface of the steel belt, thereby avoiding the waste of grinding liquid caused by the splash of grinding liquid and corrosion of other structures.

[0035] It can be understood that a retractable folded paper can be further arranged between the first shielding plate 34 and the long wall 101 to block the gap between the first shielding plate 34 and the long wall 101 to prevent the grinding liquid from splashing out.

[0036] It can be understood that a connecting rod is connected to the long wall 101, and a certain swing gap is preset between the connecting rod and the first baffle plate 34. Then, the second baffle plate 35 does not need to be hinged to one side of the first baffle plate 34, and the second baffle plate 35 can be hinged to the connecting rod.
