[0012] Compared with the prior art, the present invention provides a polishing device for copper strip processing, and has the following beneficial effects:

[0013] 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.

[0014] 2. The polishing device for copper strip processing can facilitate users to move the blade back and forth through the support frame and the support bar, so as to adjust the width of the copper strip after cutting. At the same time, the two discs can be driven to rotate through two slide grooves and four small blocks by rotating the rotating rod. In this way, the two discs can be adjusted while adjusting the position of the blade. At the same time, the rotating rod can always drive the disc to rotate. The two baffles can prevent the cut edge strips from rotating upward along the disc and affecting the use of the disc.

[0015] 3. The polishing device for copper strip processing can drive the two screws to rotate by rotating the control disk. Since the threads of the two screws are opposite, the two rings can be driven to move in opposite directions during rotation, so that the user can adjust the distance between the two blades while keeping the two blades centered.

[0016] 4. The polishing device for copper strip processing can move the pressure plate upwards through the handle, which can drive the pressure rod to move upwards, so that the two screws can be rotated back and forth. When the two blades are adjusted, the handle can be released, so that the rebound of the tension spring will drive the pressure rod to move downward to squeeze the small rod, so that the two screws can be fixed, thereby fixing the position of the two blades.

[0017] 5. The polishing device for copper strip processing moves the handle upward and then rotates the handle, which can drive the position of the two thin rods, and rotate the two thin rods to move them above the two blocks, so that the two blocks can be used for support, so that the user can rotate the screw back and forth to adjust the blade. When the blade is adjusted, pull the handle upward and then rotate it to offset the two thin rods from the two blocks, so that the handle can be loosened, and the tension spring will drive the pressure rod to move downward to fix the screw.

[0018] 6. The polishing device for processing copper strips allows users to easily replace the polishing plate through bolts and the connecting plate. The connecting plate can move up and down through the limiting block and the vertical groove, so that the polishing plate can be kept in contact with copper strips of different thicknesses for polishing.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 - 9, the present invention provides a technical solution: a polishing device for copper strip processing, including a workbench 1. On the upper side of the workbench 1, a support half-frame 12 is fixedly installed. On the upper side of the support half-frame 12, a rotation drive 11 is fixedly installed. The output shaft of the rotation drive 11 passes through the support half-frame 12 movably. At the lower end of the output shaft of the rotation drive 11, a polishing plate 38 is provided. On the upper side of the workbench 1, two fixing plates 3 are fixedly installed. Between the two fixing plates 3, two support bars 21 are provided. The front and rear ends of the two support bars 21 are respectively fixedly connected to the mutually adjacent side surfaces of the two fixing plates 3. On the two support bars 21, two cross bars 5 are provided. On the lower sides of the two cross bars 5, two blades 2 are fixedly installed. On the mutually remote sides of the two cross bars 5, two vertical bars 31 are fixedly installed. On the mutually adjacent side surfaces of the two vertical bars 31, bearings 37 are provided. The outer rings of the two bearings 37 are respectively fixedly connected to the two vertical bars 31. The inner rings of the two bearings 37 are both fixedly installed with discs 35. On the outer side walls of the two discs 35, a number of pointed blocks 29 are fixedly installed. On the front surface of the workbench 1, a mounting block 16 is fixedly installed. On the upper side of the mounting block 16, a connecting block 17 is fixedly installed. On the connecting block 17, a rotation motor 15 is fixedly installed. On the output shaft of the rotation motor 15, a rotation rod 33 is fixedly installed. The rotation rod 33 passes through the two vertical bars 31 movably. The two discs 35 are both sleeved on the rotation rod 33. By passing the copper strip to be polished through the lower part of the polishing plate 38 and then placing the copper strip on the two discs 35, the rotation motor 15 can drive the rotation rod 33 to rotate, thereby driving the two discs 35 to rotate. In this way, the pointed blocks 29 on the discs 35 can be used to drive the steel strip to move leftward, so that the steel strip can be continuously moved leftward. At the same time, the rotation drive 11 drives the polishing plate 38 to rotate to polish the steel strip. When the polishing plate 38 moves leftward to the position of the blade 2, it will be cut by the blade 2, so that the recesses poked out by the pointed blocks 29 can be cut off. In this way, it can be avoided that the thickness of the copper strip changes due to the pressure of the conveying roller driving the copper strip to move. At the same time, the width of the copper strip can be cut while polishing, so that the user can conveniently cut out a copper strip with a suitable width while polishing. On the upper sides of the two cross bars 5, two support frames 4 are fixedly installed. The four support frames 4 are respectively movably sleeved on the two support bars 21. On the rotation rod 33, two sliding grooves 34 are provided. In the two sliding grooves 34, two small blocks 36 are movably connected respectively. The two small blocks 36 are respectively fixedly connected to the parts of the two discs 35 penetrated by the rotation rod 33. On the left sides of the two vertical bars 31, two baffles 28 are fixedly installed. Through the support frames 4 and the support bars 21, the user can conveniently move the blade 2 back and forth, so as to adjust the width of the copper strip after cutting. At the same time, when the rotation rod 33 rotates, the two discs 35 can be driven to rotate through the two sliding grooves 34 and the four small blocks 36. In this way, the two discs 35 can be adjusted while adjusting the position of the blade 2. At the same time, the rotation rod 33 can always drive the disc 35 to rotate.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. A cross plate 20 is fixedly installed on the two support strips 21. A ring block 39 is fixedly installed on the cross plate 20. A small rod 18 is movably connected inside the ring block 39. Screw rods 9 are fixedly installed at both the front and rear ends of the small rod 18. The threads of the two screw rods 9 are arranged in opposite directions. Ring members 10 are threadedly sleeved on the two screw rods 9. The two ring members 10 are respectively fixedly connected to the two cross strips 5. Control discs 6 are fixedly sleeved on the two screw rods 9. Grooves 8 are opened on the upper sides of the two fixed plates 3. The two screw rods 9 are respectively movably connected to the two grooves 8. By rotating the control discs 6, the two screw rods 9 can be driven to rotate. Since the threads of the two screw rods 9 are opposite, the two ring members 10 can be driven to move in opposite directions during rotation, so that the user can conveniently adjust the distance between the two blades 2 while keeping the two blades 2 centered. A pressure rod 49 movably penetrates through the ring block 39. A pressure plate 46 is fixedly installed at the upper end of the pressure rod 49. A tension spring 48 is fixedly installed on the lower side of the pressure plate 46. The lower end of the tension spring 48 is fixedly connected to the ring block 39. A handle 44 is arranged above the pressure plate 46. The user can move the pressure plate 46 upward through the handle 44, so that the pressure rod 49 can be driven to move upward, and the two screw rods 9 can be rotated back and forth. When the adjustment of the two blades 2 is completed, the handle 44 can be released, and 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, and thus the positions of the two blades 2 can be fixed. A rotating column 45 is fixedly installed on the lower side of the handle 44. A circular groove 53 is opened in the pressure plate 46. A through groove 50 is opened on the upper inner wall of the circular groove 53. A circular plate 51 is movably connected inside the circular groove 53. The circular plate 51 is fixedly connected to the rotating column 45. A plurality of movable grooves 52 are opened on the upper side of the circular plate 51. Movable balls 54 are movably connected in each movable groove 52. Two square blocks 40 are fixedly installed on the ring block 39. Two thin rods 43 are fixedly installed on the handle 44. Limit plates 42 are fixedly installed on the two thin rods 43. Two small strips 41 are fixedly installed on the ring block 39. Limit rings 47 are fixedly installed on the two small strips 41. The two limit plates 42 are both arranged below the limit rings 47. By moving the handle 44 upward and then rotating the handle 44, the positions of the two thin rods 43 can be driven, and the two thin rods 43 can be rotated and moved above the two square blocks 40, so that the two square blocks 40 can be used for support, and thus the user can rotate the screw rods 9 back and forth to adjust the blades 2. When the blades 2 are adjusted, the handle 44 is pulled upward and rotated to stagger the two thin rods 43 from the two square blocks 40, and then the handle 44 can be released, and the tension spring will drive the pressure rod 49 to move downward to fix the screw rods 9. A connecting plate 56 is fixedly installed on the upper side of the polishing plate 38. A connecting disc 7 is arranged above the polishing plate 38. A transverse groove 25 is opened on the lower side of the connecting disc 7. The connecting plate 56 is movably connected to the transverse groove 25. Four notches 27 are opened on the connecting disc 7.Four notches 27 are internally threaded with bolts 26 passing through. The four bolts 26 are all in contact with the connecting plate 56. Four limit blocks 24 are fixedly installed on the connecting disk 7. A sleeve 55 is movably sleeved on the connecting disk 7. Four vertical grooves 22 are provided on the inner side wall of the sleeve 55. The four limit blocks 24 are respectively movably connected with the four vertical grooves 22. A rotating plate 13 is fixedly installed inside the sleeve 55. The rotating plate 13 is fixedly connected with the lower end of the output shaft of the rotation drive 11. By means of the bolts 26 and the connecting plate 56, it is convenient for the user to replace the polishing plate 38. By means of the limit blocks 24 and the vertical grooves 22, the connecting disk 7 can move up and down, so that the polishing plate 38 can keep in contact with copper strips of different thicknesses for polishing.

[0032] During use, the first step: Pass the copper strip to be polished through the lower part of the polishing plate 38, and then place the copper strip on the two disks 35. In this way, the rotating motor 15 can drive the rotating rod 33 to rotate, thereby driving the two disks 35 to rotate. In this way, the pointed blocks 29 on the disks 35 can be used to rotate and drive the steel strip to move leftward, so that the steel strip can be continuously moved leftward. At the same time, the rotation drive 11 drives the polishing plate 38 to rotate to polish the steel strip. When the polishing plate 38 moves leftward to the blade 2, it will be cut by the blade 2, so that the recesses poked out by the pointed blocks 29 can be cut off. In this way, it is possible to avoid the change in the thickness of the copper strip caused by driving the copper strip to move by the pressure of the conveying rollers, and at the same time, the width of the copper strip can be cut while polishing, so that it is convenient for the user to cut a copper strip with a suitable width while polishing.

[0033] The second step: By means of the support frame 4 and the support strip 21, it is convenient for the user to move the blade 2 back and forth, so as to adjust the width of the copper strip after cutting. At the same time, when the rotating rod 33 rotates, the two disks 35 can be driven to rotate through the two chute grooves 34 and the four small blocks 36. In this way, the two disks 35 can be adjusted while adjusting the position of the blade 2. At the same time, the rotating rod 33 can always drive the disks 35 to rotate. The two baffles 28 can prevent the cut side strips from rotating upward along the disks 35 and affecting the use of the disks 35.

[0034] The third step: By rotating the control disk 6, the two screw rods 9 can be driven to rotate. Since the threads of the two screw rods 9 are opposite, they can drive the two rings 10 to move in opposite directions when rotating, so that it is convenient for the user to adjust the distance between the two blades 2 while keeping the two blades 2 centered.

[0035] 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.

[0036] 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.

[0037] Step 6: The bolts 26 and the connecting plate 56 can facilitate users to replace the polishing plate 38, and the limit block 24 and the vertical slot 22 can make the connecting plate 7 move up and down, so that the polishing plate 38 can keep in contact with copper strips of different thicknesses for polishing.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
