[0023] The cleaning assembly 4 includes a fixed box 41, a mounting plate 42 is fixedly installed on the inner wall of the bottom surface of the fixed box 41, a reciprocating screw 43 is rotatably installed on the side wall of the mounting plate 42, a threaded plate 44 is threadedly installed on the outer surface of the reciprocating screw 43, a connecting rod 45 is fixedly installed on the side wall of the threaded plate 44, a moving plate 46 is fixedly installed on one end of the connecting rod 45, a telescopic airbag 47 is fixedly installed on the side wall of the moving plate 46, an air pipe 48 is connected and installed on the outer surface of the telescopic airbag 47, a guide pipe 49 is connected and installed on the outer surface of the air pipe 48, a nozzle 410 is connected and installed on the outer surface of the guide pipe 49, a transmission gear 411 is fixedly installed on one end of the reciprocating screw 43, and the fixed box The lower surface of 41 is fixedly connected to the upper surface of the support plate 2, the outer surface of the movable plate 46 is slidably connected to the inner wall of the fixed box 41, the side wall of the telescopic airbag 47 is fixedly connected to the inner wall of the fixed box 41, one end of the air pipe 48 extends to the outside of the fixed box 41, the nozzle 410 is aligned with the groove on the roller 3, one end of the reciprocating screw 43 extends to the outside of the side wall of the fixed box 41, a fixing rod is fixedly installed at one end of the roller 3, a driving gear is fixedly installed at one end of the fixing rod, the driving gear is meshed with a transmission gear 411, the diameter of the transmission gear 411 is smaller than the driving gear, and a cleaning rod 6 is fixedly installed on the lower surface of the fixed box 41, and one end of the cleaning rod 6 is aligned with the groove on the outer surface of the roller 3.

[0024] The specific implementation method is as follows: when the motor is used, the two rollers 3 rotate on the side wall of the support plate 2, and then the metal wire is pointed. During the pointing process, the debris on the metal wire will adhere to the groove on the roller 3. As the roller 3 rotates, the cleaning rod 6 will sweep the groove on the roller 3, and some of the debris in the groove will be swept away. Some of the debris that has not been swept away will become loose. Then, when the roller 3 rotates, it will drive the fixed gear to rotate through the fixed rod. Under the action of the transmission gear 411, the reciprocating screw 43 rotates on the side wall of the mounting plate 42. As the reciprocating screw 43 rotates, the threaded plate 44 will move through the threads on the outer surface. When the threaded plate 44 moves, it drives the movable plate 46 to move back and forth through the connecting rod 45. When the movable plate 46 moves, it squeezes the telescopic airbag 47. The gas inside the squeezed telescopic airbag 47 flows into the guide pipe 49 through the air pipe 48, and then the nozzle 410 sprays to the corresponding groove on the roller 3 to clean the metal debris in the groove, so as to avoid the presence of holes on the outer surface of the metal wire due to the presence of debris during the sharpening, resulting in a decrease in the quality of the metal wire sharpening.

[0025] The cooling assembly 5 includes two clamping plates 51, which are adapted to each other, and the interior of the clamping plates 51 is set to be hollow. The upper surface of the clamping plate 51 is provided with a water inlet 52, and the lower surface of the clamping plate 51 is provided with a notch, and a sponge 53 is fixedly installed on the inner wall of the notch. Lifting plates 54 are fixedly installed on both side walls of the clamping plate 51, and a threaded sleeve 512 is fixedly installed on the side wall of the lifting plate 54. A sliding groove is provided on the outer surface of the support plate 2, and the outer surface of the threaded sleeve 512 is slidably connected to the inner wall of the sliding groove. A bidirectional threaded rod 55 is rotatably installed on the inner wall of the bottom surface of the support plate 2, and one end of the bidirectional threaded rod 55 extends to the upper surface of the support plate 2. Outside the surface, the outer surface of the bidirectional threaded rod 55 is threadedly connected to the inner wall of the threaded sleeve 512, and a positioning plate 56 is fixedly installed on the outer surface of the bidirectional threaded rod 55, and a positioning hole 57 is provided on the side wall of the positioning plate 56, and a fixing plate 58 is fixedly installed on the outer surface of the support plate 2, and a telescopic spring 59 is fixedly installed on the side wall of the fixing plate 58, and a pull plate 510 is fixedly installed on one end of the telescopic spring 59, and a positioning pin 511 is fixedly installed on the side wall of the pull plate 510, and one end of the positioning pin 511 extends to the outside of the other side wall of the fixing plate 58. The positioning pin 511 is adapted to the size of the positioning hole, which can effectively avoid bending of the metal wire when it is pointed.

[0026] The specific implementation method is as follows: connect the water pipe to the water inlet 52. During the process of sharpening the metal wire, one end of the metal wire will be inserted between the two clamps 51. At this time, the sponge 53 will cool the pointed metal wire. According to the thickness of the metal wire after being pointed, the bidirectional threaded rod 55 is rotated. Under the action of the outer surface thread, the threaded sleeve 512 will be driven to move. At this time, the threaded sleeve 512 will drive the lifting plate 54 to move. Under the action of the lifting plate 54, the distance between the two clamps 51 will be adjusted. When the distance between the two clamps 51 is adjusted to the appropriate position, the positioning pin 511 will be inserted into the positioning hole 57 on the positioning plate 56 under the action of the telescopic spring 59 and the pull plate 510, thereby fixing the bidirectional threaded rod 55 by fixing the positioning plate 56.

[0027] Working principle: When the motor passes through, the two rollers 3 rotate on the side wall of the support plate 2, and then the metal wire is pointed. During the pointing process, the debris on the metal wire will adhere to the groove on the roller 3. As the roller 3 rotates, the cleaning rod 6 will sweep the groove on the roller 3. At this time, some of the debris in the groove will be swept away, and some debris that has not been swept away will become loose. Then, when the roller 3 rotates, it will drive the fixed gear to rotate through the fixed rod. Under the action of the transmission gear 411, the reciprocating screw 43 rotates on the side wall of the mounting plate 42. As the reciprocating screw 43 rotates, the threaded plate 44 will move through the thread on the outer surface. When the threaded plate 44 moves, it drives the moving plate 46 to move back and forth through the connecting rod 45. When the moving plate 46 moves, it will squeeze the telescopic airbag 47. The gas inside the squeezed telescopic airbag 47 passes through The air pipe 48 flows into the guide pipe 49, and then the nozzle 410 sprays toward the corresponding groove on the rolling roller 3 to clean the metal debris in the groove, and connects the water pipe to the water inlet 52. In the process of sharpening the metal wire, one end of the metal wire will be inserted between the two clamping plates 51. At this time, the sponge 53 will cool the pointed metal wire. According to the thickness of the metal wire after being pointed, the bidirectional threaded rod 55 is rotated, and the threaded sleeve 512 will be driven to move under the action of the outer surface thread. At this time, the threaded sleeve 512 will drive the lifting plate 54 to move, and the distance between the two clamping plates 51 will be adjusted under the action of the lifting plate 54. When the distance between the two clamping plates 51 is adjusted to the appropriate position, the positioning pin 511 will be inserted into the positioning hole 57 on the positioning plate 56 under the action of the telescopic spring 59 and the pull plate 510, thereby fixing the bidirectional threaded rod 55 by fixing the positioning plate 56.
