The invention provides a cable packing device which comprises a paying off device body, a measuring cable pressing device body and a winding device body which are sequentially arranged. The paying off device body comprises a paying off machine seat and a cable disc rotatably mounted on the paying off machine seat; the right end of the cable disc is connected with a pneumatic braking device main body; and the paying off machine seat is further provided with a paying off mechanism. The measuring cable pressing device body comprises a measuring cable pressing machine seat; and the cable pressing machine seat is provided with a cable leading mechanism, a cable pressing mechanism and an electronic meter device main body. The winding device body comprises a winding machine seat provided with a cable arranging mechanism and a winding mechanism. A cable on the cable disc sequentially penetrates through the paying off mechanism, the cable leading mechanism, the cable pressing mechanism, the electronic meter device main body and the cable arranging mechanism, and then is wound and packed on the winding mechanism. The cable packing device has the beneficial effects that the measuring accuracy of the cable length is improved, inertia rotation of the cable disc can be effectively braked, the cable can be wound and distributed uniformly, the service life of the device is further prolonged, and using safety of the device is guaranteed.
