Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0019] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example 1

[0021] See also Figure 1 and Figure 2As shown, a metal plate polishing device involved in this embodiment includes a belt conveyor 1 for forward and backward transmission, inner frames 2 are respectively provided on the left and right sides of the belt conveyor 1, a fixed top plate 3 arranged above the belt conveyor 1 is connected between the inner frames 2, an outer frame 4 for upward and downward movement is provided on the inner frame 2, the outer frame 4 is slidably connected to the inner frame 2, a movable top plate 5 arranged above the fixed top plate 3 is connected between the outer frames 4, and a compression spring 6 with one end connected to the fixed top plate and the other end connected to the movable top plate is provided between the movable top plate 5 and the fixed top plate 3;

[0022] The movable top plate 5 is rotatably connected to a main shaft 7 extending up and down, one end of the main shaft 7 passes through the fixed top plate 3 and is provided with a polishing disc 8 for following motion, and the other end of the main shaft 7 is provided with a first motor 9 for controlling its rotation, and the first motor 9 is provided on the movable top plate 5;

[0023] The movable top plate 5 is also rotatably connected to a lead screw 10 extending up and down, one end of the lead screw 10 passes through the fixed top plate 3 and is threadedly connected to a lead screw nut 11, the lead screw nut 11 is fixed to the fixed top plate 3, and the other end of the lead screw 10 is provided with a second motor 12 for controlling its rotation, and the second motor 12 is arranged on the movable top plate 5.

[0024] Furthermore, a linear guide rail 14 extending up and down is provided on the outer frame 4 , and a linear slider 15 is slidably connected to the linear guide rail 14 , and the linear slider 15 is fixed to the fixed top plate 3 .

[0025] Furthermore, a motor frame 16 is provided on the movable top plate 5 , and the second motor 12 is provided on the motor frame 16 .

[0026] Furthermore, the second motor 12 is a reduction motor.

[0027] In this embodiment, by operating the first motor 9 and transmitting through the main shaft 7, the polishing disc 8 rotates at a high speed for polishing.

[0028] Among them, when the second motor 12 controls the lead screw 10 to rotate clockwise, because the lead screw nut 11 is fixed to the fixed top plate 3, the movable top plate 5 moves downward relative to the fixed top plate 3, causing the polishing disk 8 on the spindle 7 to move closer to the belt conveyor 1; when the second motor 12 controls the lead screw 10 to rotate counterclockwise, because the lead screw nut 11 is fixed to the fixed top plate 3, the movable top plate 5 moves upward relative to the fixed top plate 3, causing the polishing disk 8 on the spindle 7 to move away from the belt conveyor 1.

[0029] The compression spring 6 is provided to be used as a support to prevent the load of the movable top plate 5 and its components from being concentrated entirely on the lead screw pair, thereby affecting the transmission of the lead screw pair.

[0030] The linear guide rail 14 cooperates with the linear slider 15 to provide a guide for the outer frame 4 to move up and down relative to the inner frame 2 .
