The working principle is as follows: starting the first driving member 31, the first driving member 31 drives the power shaft 49 to rotate, the power shaft 49 drives the left polishing barrel 13 to rotate, meanwhile, the power shaft 49 drives the first belt pulley 52 to rotate, the first belt pulley 52 drives the second belt pulley 30 to rotate, the second belt pulley 30 drives the right polishing barrel 13 to rotate, the power shaft 53 drives the third belt pulley 55 to rotate, the third belt pulley 55 drives the fourth belt pulley 56 to rotate, the fourth belt pulley 56 drives the pinion 57 to rotate, the pinion 57 drives the bull gear 58 to rotate, the bull gear 58 drives the third transmission shaft 59 to rotate, the third transmission shaft 59 drives the first transportation barrel 33 to rotate, the first transmission barrel 33 drives the second transmission barrel 13 to rotate, the power shaft 49 drives the fifth belt pulley 66 to rotate, the fifth belt pulley 66 drives the sixth belt pulley 28 to rotate, the sixth belt pulley 28 drives the turbofan 46 to rotate, the second driving member 8 is started, the second driving member 8 drives the transmission shaft 9 to rotate, the transmission shaft 9 drives the template 10 to rotate, after polishing is finished, 90-degree rotation can be performed through the second driving piece 8, the hand wheel 81 is rotated manually, the hand wheel 81 drives the rotating shaft 80 to rotate, the rotating shaft 80 drives the bevel gear 24 to rotate, the bevel gear 24 drives the threaded pipe 22 to rotate through meshing transmission with the bevel gear ring 25, the threaded block 21 moves upwards under the limitation of the spline grooves 78 and the splines 29, therefore, the proper lifting height of the straight rod 77 can be selected according to the thickness of jeans, and polishing can be performed at different positions through matching of the positioning hole 40 and the polishing block 41.

The transport cylinder is a metal cylindrical drum, and the size of the transport cylinder needs to be customized by a factory.

The first driving member and the second driving member are not limited to a motor, but also include a device capable of driving the device, and also include manual driving.

Has the advantages that: the jeans front and back polishing device is simple in structure, the front and back surfaces of jeans can be polished at one time, the working efficiency is improved, and the labor is saved.
