[0045] Working principle: the wide temperature range cable filling material injection equipment realizes efficient and stable filling of the cable through the cooperation of the injection assembly, the temperature control assembly and the conveying assembly. The conveying assembly is the basis for material transmission. The conveying pump 3 is made of stainless steel, a special material resistant to high and low temperatures, with a temperature resistance range of-50 to 150 DEG C. The conveying blade 4 rotating in the middle of the inner wall generates power when in operation, sucking the filling material from the injection hole 5 and pushing it into the pipeline 1. The inner layer material of the pipeline 1 system is polytetrafluoroethylene. The pipeline 1 system adopts a double-layer structure. The inner layer of corrosion-resistant material ensures the pure conveying of the filling material, and the outer layer of heat preservation material cooperates with the temperature control assembly to maintain the stability of the material temperature. The temperature control assembly adjusts the material temperature flexibly according to the ambient temperature. When in a low-temperature environment, the heating module 8 fixedly connected to the left side of the outer wall of the conveying pump 3 starts to work, heating the filling material to ensure its fluidity. The heating module 8 adopts a ceramic heater with a power of 500 W. In a high-temperature environment, the cooling module is installed outside the conveying pipeline 1 to cool the material, preventing the material from deteriorating or changing its performance due to excessive temperature. The temperature instrument 9 installed on the rear side of the outer wall of the conveying pump 3 monitors the material temperature in real time, and the internal rotating pointer 19 directly displays the temperature data, so that the operator can adjust the temperature control assembly in time. The injection assembly ensures precise and reliable filling process. The injection port is connected with the filling cavity of the cable.

[0046] The screw nut 201 is fixed to the inner wall of the pipeline 1 as the mounting base of the whole structure, and the motor 203 is fixed to the left side of the inner wall of the screw nut 201.
