[0038] The driven pulley 71 has a larger diameter than the driving pulley 72 , the belt pulley 73 , and the driving pulley 74 .

[0039] When polishing the printing plate roller body 21, the operator first moves the two handles 34 away from each other, and the two handles 34 drive the two hexagonal clamping shafts 32 to move away from each other, and the two clamping springs 33 are compressed accordingly. Then the operator places the printing plate roller body 21 between the two hexagonal clamping shafts 32, and then the operator releases the two handles 34. Under the action of the two clamping springs 33, the two hexagonal clamping shafts 32 move toward each other, and the two hexagonal clamping shafts 32 clamp the printing plate roller body 21. Then the operator starts the telescopic rods of the four electric push rods 63 to retract, and the four push rods 63 are retracted. The electric push rod 63 drives the two driving frames 62 to move downward. Under the action of the two inclined grooves on the upper parts of the two driving frames 62, the two rollers 1 64 and the two rollers 2 65 move toward each other. The two rollers 1 64 drive the sliding frame 41, the guide roller 42, the driving roller 43, the polishing belt 44 and the two driving pulleys 72 to move toward the printing plate roller body 21. The polishing belt 44 is in contact with one side of the printing plate roller body 21. The two rollers 2 65 drive the sliding plate 51, the bidirectional screw rod 52, the bidirectional nut 53, the brush plate 54 and the two pulleys 73 to move toward the printing plate roller body 21. The brush plate 54 is in contact with the other side of the printing plate roller body 21; under the action of the tensioning spring 77, the sliding block 76 and the tensioning wheel 78 will move away from the printing plate roller body 21, thereby tensioning the toothed belt 79 so that the toothed belt 79 can be in contact with the driven pulley 71, the driving pulley 72, the pulley 73 and the active pulley 74. The operator starts the two motors 75, and the two motors 75 drive the two active pulleys 74 to rotate. The two active pulleys 74 drive the two toothed belts 79 to run, and the two toothed belts 79 can drive the two driven pulleys 71, the two driving pulleys 72 and the two pulleys 73 to rotate. The driven pulley 71 drives the two hexagonal rotating shafts 31, the two hexagonal clamping shafts 32, the two clamping springs 33 and the two handles 34 to rotate, and the two hexagonal clamping shafts 32 drive the two printing plate roller bodies 21 to rotate. Since the diameter of the driven pulley 71 is larger than the driving pulley 72, the belt pulley 73 and the active pulley 74, when the driven pulley 71, the driving pulley 72, the belt pulley 73 and the active pulley 74 are driven to rotate by the toothed belt 79, the rotation speed of the driven pulley 71 will be lower than that of the driving pulley 72, the belt pulley 73 and the active pulley 74, so the rotation speed of the printing plate roller body 21 will also be lower than that of the polishing belt 44.The two driving pulleys 72 rotate to drive the driving roller 43, and the driving roller 43 rotates to drive the polishing belt 44, and the polishing belt 44 drives the three guide rollers 42 to rotate, and the polishing belt 44 can polish the printing plate roller body 21 with a slower rotation speed, and the two pulleys 73 drive the bidirectional nut 53 to rotate, and the nut rotation drives the bidirectional nut 53 to reciprocate along the sliding plate 51, and the bidirectional nut 53 drives the brush plate 54 to reciprocate, and the brush plate 54 can brush out the burrs in the depression on the printing plate roller body 21, so that the printing plate roller body 21 can be polished more fully, so that the burrs in the depression can be brushed out while polishing, thereby improving the polishing effect and efficiency of the printing plate roller body 21; during the polishing process, the operator controls the telescopic rods of the four electric push rods 63 to continuously reciprocate, and the four electric push rods 63 drive the two driving frames 62 to continuously reciprocate, under the action of the two inclined grooves on the upper parts of the two driving frames 62 Under the condition that the two rollers 1 64 and the two rollers 2 65 continuously reciprocate, the two rollers 1 64 and the two rollers 2 65 drive the polishing belt 44 and the brush plate 54 to continuously reciprocate, so that the contact force between the polishing belt 44 and the brush plate 54 and the printing plate roller body 21 can be adjusted, so that the printing plate roller body 21 can be polished and cleaned more fully, thereby further improving the polishing effect of the printing plate roller body 21. After the printing plate roller body 21 is polished, the operator turns off the motor 75, and then controls the telescopic rods of the four electric push rods 63 to extend and reset, thereby moving the polishing belt 44 and the brush plate 54 away from each other, and then the operator moves the two handles 34 away from each other, and the two handles 34 drive the two inner six-hole clamping shafts 32 to move away from each other, and the two clamping springs 33 are compressed accordingly, and then the operator takes out the polished printing plate roller body 21. ;

[0040] Embodiment 2: Based on embodiment 1, Figure 8-Figure 11 As shown, it also includes an adjustment mechanism, which is arranged on the box body 1, the side plate 2 and the brush plate 54.

A corrugated groove plate 82 is slidably provided between the two side plates 2, and a corrugated groove is opened on the corrugated groove plate 82. The protrusion on the multi-groove frame 81 is located in the corrugated groove on the corrugated groove plate 82. A driving block 83 is slidably provided on the box body 1.

A threaded rod 85 is rotatably provided on the box body 1, and the threaded rod 85 is threadedly connected to the driving nut 84.

[0041] When encountering a more stubborn burr in the depression of the printing plate roller body 21, the operator uses the hexagonal wrench to turn the threaded rod 85 forward and backward, and the threaded rod 85 drives the drive nut 84 to move toward the printing plate roller body 21 or away from the printing plate roller body 21, and the drive nut 84 drives the drive block 83, the corrugated groove plate 82 and the multi-groove frame 81 to move toward the printing plate roller body 21 or away from the printing plate roller body 21. The multiple grooves on the multi-groove frame 81 can limit the bristles on the brush plate 54, so that the brush can be adjusted. The exposed length of the bristles on the plate 54 can adjust the force with which the bristles on the brush plate 54 brush the recessed area of ​​the printing plate roller body 21, thereby being able to adapt to different degrees of burrs in the recessed area of ​​the printing plate roller body 21. The protrusions on the multi-slot frame 81 reciprocate in the corrugated grooves of the corrugated groove plate 82, and the multi-slot frame 81 can fine-tune the brushing force of the bristles on the brush plate 54, thereby being able to more fully brush out different degrees of burrs in the recessed area of ​​the printing plate roller body 21, thereby further improving the polishing effect of the printing plate roller body 21.

A plurality of toggle bars 95 are installed on the ends of the two horizontal shafts 93 that are close to each other. The two driving gears 91 are located on one side of the two driven gears 92.

[0043] When the bidirectional lead screw 52 moves toward the direction close to the printing plate roller body 21, the bidirectional lead screw 52 drives the two driving gears 91 to move toward the direction close to the printing plate roller body 21, and the two driving gears 91 can mesh with the two driven gears 92. The rotation of the bidirectional lead screw 52 drives the two driving gears 91 to rotate, and the two driving gears 91 drive the two driven gears 92 and the two column gears 94 to rotate.
