[0012] Compared with the prior art, the present invention provides a polishing device for copper strip processing, which has the following beneficial effects: 1. The polishing device for copper strip processing passes the copper strip to be polished under the polishing plate, and then places the copper strip on two discs, so that the rotating motor can drive the rotating rod to rotate, thereby driving the two discs to rotate, so that the steel strip can be driven to move to the left by the rotation of the sharp block on the disc, so that the steel strip can be continuously moved to the left, and the polishing plate can be driven to rotate by the rotary drive to polish the steel strip, and when the polishing plate moves to the left to the blade, it will be cut by the blade, so that the concave part inserted by the sharp block can be cut off, so that the copper strip thickness can be avoided from being driven to move by the pressure of the conveying roller, and the copper strip thickness can be changed, and the width of the copper strip can be cut while polishing, so that the user can cut a copper strip of suitable width while polishing.

[0013] 2.

The two baffles 28 can prevent the cut edge strips from rotating upward along the disc 35 and affecting the use of the disc 35.

[0025] Step 3: By rotating the control disk 6, the two screws 9 can be driven to rotate. Since the threads of the two screws 9 are opposite, the two rings 10 can be driven to move in opposite directions during rotation, so that the user can adjust the distance between the two blades 2 while keeping the two blades 2 centered.

[0026] Step 4: The user can move the pressure plate 46 upward through the handle 44, which can drive the pressure rod 49 to move upward, so that the two screw rods 9 can be rotated back and forth. When the two blades 2 are adjusted, the handle 44 can be released, so that the rebound of the tension spring will drive the pressure rod 49 to move downward to squeeze the small rod 18, so that the two screw rods 9 can be fixed, thereby fixing the position of the two blades 2.

[0027] Step 5: Move the handle 44 upward and then rotate it, so that the position of the two thin rods 43 can be driven, and the two thin rods 43 can be rotated and moved above the two blocks 40, so that the two blocks 40 can be used for support, so that the user can rotate the screw 9 back and forth to adjust the blade 2. When the blade 2 is adjusted, pull the handle 44 upward and then rotate it to stagger the two thin rods 43 and the two blocks 40, so that the handle 44 can be released, and the tension spring will drive the pressure rod 49 to move downward to fix the screw 9.
