[0021] A rotating bearing 3 is rotatably connected inside the side plate 2, and the wire winding rod 27 is rotatably connected to the side plate 2 through the rotating bearing 3. By setting the rotating bearing 3, the rotating bearing 3 is used to bear and limit the wire winding rod 27, reducing the frictional resistance between the wire winding rod 27 and the side plate 2, thereby improving the use effect of the wire winding rod 27.

[0022] Two bottom cylinders 4 are fixedly connected to the top of the workbench 1, and a clamping rod 41 is rotatably connected to the top of each bottom cylinder 4. By setting the clamping rod 41, one end of the heating wire passes through the two clamping rods 41 and is wound around the wire winding rod 27, limiting one end of the heating wire, thereby improving the winding effect of the heating wire.

[0023] An upper gear ring 5 is rotatably connected to the bottom of the workbench 1, an upper slide rail 51 is fixedly connected to the bottom of the upper gear ring 5, a lower slide rail 52 is rotatably connected to the bottom of the upper slide rail 51, and a lower gear ring 53 is fixedly connected to the bottom of the lower slide rail 52. By setting the upper gear ring 5 and the lower gear ring 53, the upper gear ring 5 and the lower gear ring 53 drive the upper slide rail 51 and the lower slide rail 52 to rotate in opposite directions, and the upper slide rail 51 and the lower slide rail 52 drive the two sliding rods 28 and the cutting knife 29 to move towards the heating wire, thereby completing the cutting process of the heating wire.

[0024] Two bottom blocks 6 are fixedly connected to the bottom of the workbench 1, a telescopic rod 61 is slidably connected between the two bottom blocks 6, one end of the telescopic rod 61 penetrates through the bottom block 6 and is fixedly connected to a push plate 62, and an upper rack 63 and a lower rack 64 are fixedly connected to the side of the push plate 62 away from the telescopic rod 61. By setting the upper rack 63 and the lower rack 64, the upper rack 63 and the lower rack 64 are meshed with the upper gear ring 5 and the lower gear ring 53, thereby driving the upper gear ring 5 and the lower gear ring 53 to rotate in opposite directions.

[0025] A moving plate 7 is threadedly sleeved on the outer side wall of the first lead screw 25. A moving groove 71 is formed in the top of the workbench 1. The bottom end of the moving plate 7 penetrates through the moving groove 71. By arranging the moving plate 7, the first lead screw 25 drives the moving plate 7 to slide along the moving groove 71, so that the moving plate 7 pushes the telescopic rod 61.

[0026] On one side of the two sliding rods 28 close to each other, a resisting circular block 8 is fixedly connected. By arranging the resisting circular block 8, during the process of the two sliding rods 28 moving towards each other, the sliding rods 28 are limited, preventing the sliding rods 28 from driving the two cutting blades 29 to impact each other, and thus protecting the cutting blades 29.

[0027] Working principle: By starting the motor 12, the motor 12 drives the rotating cylinder 22 to rotate through the output end. The rotating cylinder 22 drives the rotating rod 24 inside it to rotate synchronously. The rotating rod 24 drives the first lead screw 25 and the second lead screw 26 to rotate. Under the action of the threaded cylinder 23, the second lead screw 26 drives the wire winding rod 27 to move spirally towards the side plate 2, so that the wire winding rod 27 winds the heating wire outside it. At the same time, the first lead screw 25 drives the moving plate 7 outside it to slide along the moving groove 71. The moving plate 7 pushes the telescopic rod 61 to move upwards towards the upper gear ring 5 through its bottom end. The telescopic rod 61 drives the upper rack 63 and the upper gear ring 5 to be meshed and connected, and the lower rack 64 and the lower gear ring 53 to be meshed and connected through the push plate 62, so that the upper gear ring 5 and the lower gear ring 53 drive the upper slide rail 51 and the lower slide rail 52 to rotate in the opposite direction. Under the limiting action of the upper slide rail 51 and the lower slide rail 52, the upper slide rail 51 and the lower slide rail 52 drive the two sliding rods 28 to move towards each other. The two sliding rods 28 drive the two cutting blades 29 to move towards the heating wire, so that the two cutting blades 29 cut the heating wire, avoiding manual cutting of the heating wire on the wire winding rod 27, thereby reducing the labor intensity of workers and improving the production efficiency of the heating wire.
