[0027] A cable processing raw material feeding device, such as Figures 1 to 4 As shown, it includes a high-pressure gas chamber 2, a particle container chamber 3, and a feed storage container 5. The high-pressure gas chamber 2 has an air-material mixing chamber 21 formed inside. The high-pressure gas chamber 2 is provided with a feed pipe 1 connected to the air-material mixing chamber 21. The feed pipe 1 is a hose. A high-pressure air inlet 22 connected to the air-material mixing chamber 21 is provided on the side of the high-pressure gas chamber 2.

[0029] The particle container chamber 3 is hingedly connected to a rocker arm 6, one end of which is equipped with a lever 61, which extends into the lower end of the particle container chamber 3. The cable processing raw material feeding device also includes a reciprocating drive device 7, which drives the rocker arm 6 to swing back and forth, thereby driving the lever 61 to reciprocate within the particle container chamber 3. A rotating drum 75 is mounted on the upper end of the feed accumulator 5. The rotating drum 75 is connected to the upper end of the feed accumulator 5 via a bearing, and the exhaust port 52 is located within the rotating drum 75.
