DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0024] Example

[0025] like Figure 1 , Figure 4 As shown, Figure 1 Shown is an overall schematic diagram of a polishing machine in an embodiment, Figure 4 Shown is a schematic diagram of a high drum roller in an embodiment.

[0026] The device comprises a fixed seat 11, and a plurality of polishing wheel assemblies 20 with lifting functions are arranged at equal intervals on the upper end of the fixed seat 11. By arranging the polishing wheel assemblies 20 with lifting functions, the device is suitable for grinding the middle and high drum rollers 1 with inconsistent overall heights.

[0027] like Figure 2 , Figure 3 As shown, Figure 2 Shown is a schematic diagram of a polishing wheel assembly in an embodiment, Figure 3 Shown is a schematic diagram of a driving structure in an embodiment.

[0028] The polishing wheel assembly 20 includes a fixed frame 21, which is arranged at the upper end of the fixed seat 11. The fixed frame 21 includes a vertical section and a horizontal section at the top. A mounting seat 22 is arranged on the front side of the fixed frame 21, and a polishing wheel 23 is arranged on the mounting seat 22. Specifically, ten polishing wheel assemblies 20 are arranged.

[0029] The utility model also includes a lifting structure, which drives the mounting seat 22 to move up and down in the vertical direction to adjust the height of the polishing wheel 23.

[0030] By setting up a lifting structure, the mounting seat 22 of each polishing wheel assembly 20 can move up and down in the vertical direction, thereby adjusting the height of the polishing wheel 23 of each polishing wheel assembly 20, so that the height of the polishing wheel 23 of each polishing wheel assembly 20 matches the surface height of the middle and high drum roller 1, thereby achieving polishing of middle and high drum rollers 1 of different heights.

[0031] The lifting structure includes a screw 41, which is vertically inserted in the mounting seat 22. The top of the screw 41 is rotatably connected to the horizontal section of the fixing frame 21. The contact surfaces of the screw 41 and the mounting seat 22 are both processed with arc-shaped spiral grooves. The two are sleeved together to form a spiral raceway, and the raceway is equipped with balls that provide power for the mounting seat 22 to move up and down when the screw 41 rotates.

[0032] The lifting structure also includes a driving member 42 and a gearbox 43, both of which are arranged at the top of the horizontal section of the fixed frame 21, the output shaft of the driving member 42 is connected to the input end of the gearbox 43, and the output end of the gearbox 43 is connected to the screw 41.

[0033] The driving member 42 is a servo motor, which drives the screw 41 to rotate. The rotation of the screw 41 causes the balls at the contact surface between the mounting seat 22 and the screw 41 to roll along the raceway, thereby realizing the up and down movement of the mounting seat 22 on the surface of the screw 41, and the rear end wall of the mounting seat 22 is against the fixing frame 21, thereby limiting the rotation of the mounting seat 22 and realizing the lifting and lowering of the mounting seat 22 in the vertical direction.

[0034] By setting up this lifting structure, since the balls and guide rails move in coordination and many small ball points have contact friction, the lifting and adjusting process is smoother, and through the coordination with the driving member 42 and the gearbox 43, it has the effects of precise transmission, high efficiency and flexible transmission.

[0035] The transmission structure 30 is disposed on the mounting seat 22 and drives the polishing wheel 23 to rotate.

[0036] The driving structure includes a second driving member 31 and a bearing seat 35. The second driving member 31 is arranged on the upper end surface of the mounting seat 22 behind the screw 41. The bearing seat 35 is arranged on the front end surface of the mounting seat 22. A horizontal connecting shaft 36 is arranged in the bearing seat 35 and one end of which is connected to the polishing wheel 23. A driving wheel 32 is fixedly sleeved on the output shaft of the second driving member 31. A driven wheel 33 is fixedly sleeved on the end of the connecting shaft 36 away from the polishing wheel 23. A belt 34 is sleeved on the outside of the driving wheel 32 and the driven wheel 33.

[0037] The second driving member 31 is a three-phase motor, which drives the driving wheel 32 with a belt 34 to rotate, and the driven wheel 33 is driven to rotate through the taut belt 34, thereby driving the connecting shaft 36 connected to the polishing wheel 23 in the bearing seat 35 to rotate, that is, driving the polishing wheel 23 to rotate for polishing.

[0038] A protective sleeve 44 is also sleeved on the outside of the screw rod 41 . The protective sleeve 44 protects the screw rod 41 and does not affect the lifting and lowering movement of the mounting seat 22 on the surface of the screw rod 41 .

[0039] Working principle: When using this device to polish the surface of the medium and high drum roller 1, first place the polishing machine as a whole parallel to one side of the medium and high drum roller 1, and then adjust the height of the polishing wheel assembly 20 according to the height of the area to be polished of the medium and high drum roller 1. The adjustment method is as follows: turn on the driving member 1 42 to drive the screw 41 to rotate. The rotation of the screw 41 causes the balls at the contact surface between the mounting seat 22 and the screw 41 to roll along the raceway, so that the mounting seat 22 moves up and down along the length direction of the screw 41, thereby realizing the adjustment of the height of the polishing wheel 23. After the height adjustment is completed, turn on the driving member 2 31, and the driving member 2 31 drives the active wheel 32 with the belt 34 to rotate, and drives the driven wheel 33 to rotate through the tightened belt 34, thereby driving the connecting shaft 36 connected to the polishing wheel 23 in the bearing seat 35 to rotate, that is, the rotation of the polishing wheel 23 is realized, and polishing work is performed.

[0040] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
