Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-7This invention provides a technical solution for a four-sided calender leveling machine: The four-sided calender leveling machine includes a worktable 1, a mounting frame 2 mounted on the upper surface of the worktable 1, a calendering assembly inside the mounting frame 2, and a transmission assembly mounted on the rear surface of the mounting frame 2. The calendering assembly includes four rectangular U-shaped frames 3 mounted inside the mounting frame 2. A calendering roller 4 is rotatably mounted between the two side walls of each U-shaped frame 3. A first gear 5 is mounted on the side of each calendering roller 4. The four calendering rollers 4 together form a calendering opening. The transmission assembly includes two first fixed frames 6 located on one side of the upper and lower U-shaped frames 3 and fixedly connected to the mounting frame 2. Each U-shaped frame 3... A second gear 7, meshing with a first gear 5 on a corresponding U-shaped frame 3, is rotatably mounted between the two side walls of the first fixed frame 6. A second fixed frame 13 is mounted on one side of each of the left and right U-shaped frames 3 on the rear surface of the mounting frame 2. A third gear 14, meshing with a first gear 5 on a corresponding U-shaped frame 3, is rotatably mounted between the two side walls of each second fixed frame 13. A first synchronous pulley 8 is rotatably mounted on the lower surface of each first fixed frame 6, and a second synchronous pulley 9 is rotatably mounted on one side of each first synchronous pulley 8 on the lower surface of each first fixed frame 6. Each first synchronous pulley 8 and its corresponding second synchronous pulley 9 on the first fixed frame 6 are... A first synchronous belt 10 is provided. One end of each second synchronous pulley 9 passes through the first fixed frame 6 and is fixedly connected to a third gear 14. One end of each first synchronous pulley 8 passes through the first fixed frame 6 and is equipped with a first bevel tooth 11. One end of each second gear 7 passes through the side wall of the first fixed frame 6 and is equipped with a second bevel tooth 12 that meshes with the corresponding first bevel tooth 11. Mounting seats 15 are installed on the front surface of the mounting frame 2 on the other side of the upper and lower U-shaped frames 3. A fourth gear 16 that meshes with the first gear 5 on the corresponding U-shaped frame 3 is rotatably installed in each mounting seat 15. In use, the two rotating fourth gears 16 are connected by a transmission. The two first gears 5 meshing with it drive the upper and lower calendering wheels 4 to rotate. Then, the two rotating first gears 5 drive the two second gears 7 to rotate, which in turn drive the second bevel gear 12 to rotate. The first bevel gear 11 drives the first synchronous pulley 8 to rotate, and the first synchronous belt 10 drives the corresponding second synchronous pulley 9 to rotate, which in turn drives the third gear 14 connected to it to rotate. Then, the two rotating third gears 14 drive the two left and right first gears 5 to rotate, which in turn drive the two calendering wheels 4 distributed on the left and right to rotate. When the round wire enters the calendering hole, the four rotating calendering wheels 4 calender the round wire into a square wire.

[0022] A second bracket 26 is mounted on the upper surface of the workbench 1 and the front surface of the mounting frame 2. An input wheel 27 is rotatably mounted on the second bracket 26. A protective cover 24 covering all the first fixed frames 6 and the second fixed frames 13 is mounted on the rear surface of the mounting frame 2. An opening 25 aligned with the calendering hole is opened on the side of the protective cover 24. A first bracket 22 is mounted on one side of the upper surface of the workbench 1 and the protective cover 24. An output wheel 23 is rotatably mounted on the first bracket 22. In use, the round wire is passed around the input wheel 27 and inserted into the calendering hole, and then passed out through the opening 25 and around the output wheel 23.

[0023] A dual-axis drive box 17 is mounted on one side of the mounting bracket 2 on the upper surface of the workbench 1. Both output ends of the dual-axis drive box 17 are equipped with drive shafts 28 that extend into the corresponding mounting base 15 and are connected to the fourth gear 16. A motor 18 is mounted on one side of the dual-axis drive box 17 on the upper surface of the workbench 1. A third synchronous pulley 19 is mounted on the output end of the motor 18. A fourth synchronous pulley 20 is mounted on the input end of the dual-axis drive box 17. A second synchronous belt 21 is provided between the fourth synchronous pulley 20 and the third synchronous pulley 19. In use, the running motor 18 drives the two drive shafts 28 on the dual-axis drive box 17 to rotate through the third synchronous pulley 19, the fourth synchronous pulley 20 and the second synchronous belt 21, thereby driving the two fourth gears 16 to rotate.

[0024] The working principle of this invention is as follows: A circular wire is passed around the input wheel 27 and into the calendering hole, then exits through the opening 25 and passes around the output wheel 23. The running motor 18 drives the two transmission shafts 28 on the dual-shaft drive box 17 to rotate via the third synchronous wheel 19, the fourth synchronous wheel 20, and the second synchronous belt 21. This, in turn, drives the two fourth gears 16 to rotate. The two rotating fourth gears 16, through their meshing with the two first gears 5, drive the upper and lower calendering wheels 4 to rotate. Then, the upper and lower rotating first gears 5 drive the two second gears 7 to rotate, which in turn drives the second bevel gear 12 to rotate. The first synchronous pulley 8 is driven to rotate by the first bevel gear 11, which in turn drives the corresponding second synchronous pulley 9 to rotate via the first synchronous belt 10. This drives the third gear 14 connected to it to rotate. Then, the two rotating third gears 14 drive the two left and right first gears 5 to rotate, which in turn drive the two left and right calendering rollers 4 to rotate. The four rotating calendering rollers 4 drive the round wire forward. When the round wire enters the calendering hole, the four rotating calendering rollers 4 calender the round wire to make it into a square wire. Then, the square wire is discharged from the opening 25, passes around the output wheel 23 and enters the collection box.
