[0036] Specifically, in use, the cable first needs to pass through the gap between the rotating wheel one 13 and the rotating wheel two 14 on the longitudinal frame 2, when the thicker cable enters, the rotating wheel one 13 and the rotating wheel two 14 will be forced to drive the sliding block 11 to move along the outer wall of the guide column 10, the movement of the sliding block 11 will exert pressure on the spring 12 connected to the top of the sliding block 11, causing the spring 12 to contract, and the elasticity of the spring 12 allows the rotating wheel one 13 and the rotating wheel two 14 to closely fit the outer wall of the cable of different sizes, at this time the output end of the motor 8 will drive the rotating wheel two 14 to start rotating, forming a continuous conveying of the cable, when the cable passes through the rotating wheel one 13 and the rotating wheel two 14 inside the longitudinal frame 2, it smoothly enters another set of rotating wheel one 13 and rotating wheel two 14 above the transverse frame 3, ensuring smooth transmission of the cable, finally the cable will be conveyed to the stop block 5 inside the fixed frame 4, the output end of the cylinder 6 will push the pressing block 7 to move finely, so that the pressing block 7 can effectively exert pressure on the cable to achieve stable fixation, thereby effectively ensuring the straightening effect of the cable during crimping and improving the quality and stability of the connection.

[0037] Referring to Figure 1 , Figure 2 and Figure 5 , the cleaning assembly includes a fixed frame 15 and a fan 16, the fixed frame 15 is fixedly connected to the top of the machine body 1, providing stable support, the fan 16 is arranged inside the fixed frame 15, ensuring smooth flow of air, effectively improving cleaning efficiency, the machine body 1 is internally provided with a discharge port 17, facilitating material discharge and ensuring operation safety, the machine body 1 is fixedly connected with a baffle 18 on the top, the machine body 1 is fixedly connected with a pipeline 19 inside, the pipeline 19 is in communication with the discharge port 17, making the material conveying efficient, the pipeline 19 is fixedly connected with a dust extraction pipe 20 inside, for strongly adsorbing dust and sundries, keeping the working environment clean, the dust extraction pipe 20 is fixedly connected to the inside of the machine body 1, the dust extraction pipe 20 is provided with a dust extraction fan inside, the machine body 1 is slidingly connected with a collection box 21 inside, so that the collection box 21 can move flexibly for cleaning and maintenance, the machine body 1 is fixedly connected with a support block 22 inside, providing additional stability for the entire assembly, the support block 22 is rotatably connected with an electric push rod 23 inside, the output end of the electric push rod 23 is rotatably connected with a cutting machine 24, ensuring that the cutting machine 24 can maintain stable cutting action during work, the machine body 1 is fixedly connected with a support frame 25 on the top, providing necessary structural support for the cutting machine 24, ensuring that it does not shake during operation, the cutting machine 24 is rotatably connected inside the support frame 25.

[0038] Specifically, after the cable is pressed, the output end of the electric push rod 23 drives the cutting machine 24 to rotate inside the support frame 25, so that one side of the cutting tool of the cutting machine 24 is pressed on the exposed cable, ensuring that the cable remains flat during cutting. At the same time, the fan 16 is started to cool the cutting machine 24 to prevent overheating of the cutting tool, which can cause wear. In addition, the strong airflow generated by the fan 16 not only helps to cool, but also effectively blows the cut-off cable ends and waste generated during cutting to the side of the baffle 18. The design of the baffle 18 is to effectively block these waste materials, ensuring that they fall into the discharge opening 17 inside the machine body 1. In this process, the cable ends fall freely into the pipeline 19 by gravity. The structure of the pipeline 19 helps to smoothly guide the cable ends to fall. At the same time, the dust extraction fan inside the dust extraction pipe 20 can extract waste and dust from the pipeline 19 in real time, ensuring a clean working environment. At the same time, the cable ends fall inside the pipeline 19 to the collection box 21, finally achieving efficient collection and processing of the cable ends and waste.

[0039] Working principle: when using the terminal crimping machine, first pass the cable between the rotating wheel one 13 and the rotating wheel two 14 inside the longitudinal frame 2. When the rotating wheel one 13 and the rotating wheel two 14 contact the thicker cable, they will be forced to drive the sliding block 11 on the outer wall of the guide column 10, and at the same time the sliding block 11 will extrude the spring 12 connected to the top, making it shrink. Through the elasticity of the spring 12 itself, the rotating wheel one 13 and the rotating wheel two 14 can tightly fit the outer wall of the cable of different sizes. At the same time, the output end of the motor 8 drives the rotating wheel two 14 to rotate, so that the rotating wheel two 14 conveys the cable. When the cable passes through the rotating wheel one 13 and the rotating wheel two 14 inside the longitudinal frame 2, it will then enter another set of rotating wheel one 13 and rotating wheel two 14 above the horizontal frame 3. Finally, the cable is conveyed to the stop block 5 inside the fixed frame 4. At this time, the output end of the air cylinder 6 pushes the pressing block 7 to move, so that the pressing block 7 extrudes and fixes the cable, thereby achieving the effect of effectively straightening the cable during pressing. After the cable is pressed, the output end of the electric push rod 23 drives the cutting machine 24 to rotate inside the support frame 25, so that one side of the cutting tool of the cutting machine 24 is pressed on the exposed cable, cutting it, ensuring that the cable remains flat during terminal crimping. During cutting, the fan 16 can be started to cool the cutting machine 24, and at the same time the airflow of the fan 16 can blow the cut-off cable ends and waste generated during cutting to the side of the baffle 18, so that the cable ends are blocked by the baffle 18 and fall into the discharge opening 17 inside the machine body 1, and then fall into the pipeline 19 through the discharge opening 17. At this time, the dust extraction pipe 20 and the dust extraction fan inside it can extract waste and dust from the pipeline 19 outside the machine body 1. At the same time, the cable ends fall freely inside the pipeline 19 into the collection box 21 inside the machine body 1 for collection, thereby achieving the effect of effectively collecting and processing the cable ends and waste.
