When the servo motor 41 drives the grinding disc 44 to rotate, the friction force causes the end of the inner drum to be ground according to the pre-set shape of the annular groove. By rotating the gear ring 22 meshing with the bevel gear 23, a number of adjustment plates 24 with equal spacing in an annular shape are driven to slide on the surface of the mounting frame 21, so that the staff can adjust according to different inner drum sizes and conveniently clamp the inner drums of washing machines of different sizes.

[0034] In this embodiment, the top surface of the base 1 is fixedly connected to a mounting seat 11 for fixing the mounting frame 21 by bolts, and a mounting groove 210 for accommodating the rotation of the gear ring 22 is opened inside the mounting frame 21. The side wall of the mounting frame 21 away from the grinding structure 4 is fixedly connected to a limit plate 28 for limiting the movement of the inner roller body 5 by a plurality of connecting blocks 27, which is convenient for clamping the inner roller body 5 to prevent the inner roller body 5 from moving due to force during grinding and affecting the grinding effect.

[0035] Then, a spiral groove for accommodating a plurality of adjustment plates 24 for spiral sliding connection is opened on one side wall of the gear ring 22 away from the tooth surface, and a slider adapted to the spiral groove is provided on the side wall of the adjustment plate 24 close to the gear ring 22. The longer two side walls of the adjustment plate 24 are slidably connected to the side walls of the mounting frame 21, and a plurality of support plates 221 for supporting the sliding of the adjustment plates 24 are installed on the circumferential outer wall of the gear ring 22. The number of support plates 221 is consistent with the number of adjustment plates 24, and the spacing of a plurality of rotating blocks 26 is adjusted by moving a plurality of adjustment plates 24 arranged at equal intervals in a ring shape, thereby facilitating the clamping of inner roller bodies 5 of different sizes.

[0036] Next, the adjustment structure 3 includes a transmission rod 31 coaxially connected to the bevel gear 23 , and one end of the transmission rod 31 away from the bevel gear 23 is coaxially connected to a rotating rod 32 to facilitate the rotation of the bevel gear 23 .

[0037] Furthermore, a transmission ring 33 is sleeved and fixed on the outer wall of the rotating rod 32 , and a handle 34 is installed on the side wall of the transmission ring 33 , so that the staff can rotate the bevel gear 23 conveniently.

A side wall of the grinding disc 44 close to the inner roller body 5 is provided with an annular groove for grinding the inner roller. The inner walls on both sides of the annular groove are tightly fitted with the end of the inner roller body 5 during the grinding process. When the servo motor 41 drives the grinding disc 44 to rotate, the friction force causes the end of the inner roller to be ground according to the pre-set shape of the annular groove. The threaded connecting tube 43 and the grinding disc 44 are detachably connected, which facilitates the replacement of the grinding disc and improves practicality.

[0041] It should be supplemented that a vertical plate 12 for mounting the servo motor 41 is provided at one end of the top surface of the base 1 away from the mounting seat 11 to facilitate normal use of the structure.
