[0027] Feeding baffle 21 is designed as two layers same part, the bottom end of feeding frame 25 and the top end of main frame 1 are fixedly connected, and the outer wall of fixed cross bar 24 and the inner wall of feeding baffle 21 are slidingly connected.
[0028] Crushing mechanism 5 includes crushing roller 52, both ends of crushing roller 52 are rotationally connected with the inner wall of main frame 1, a motor 51 is arranged outside the crushing roller 52, the motor 51 is fixedly connected with the outer wall of main frame 1 through a rack, and the output end of the motor 51 is fixedly connected with the outer wall of the crushing roller 52.
[0029] Inert gas recovery mechanism 3 includes a tank body 31, a filter plate 32 is clamped on the inner wall of the tank body 31, a gas pump 33 is fixedly connected to the outer wall of the tank body 31, and a gas pipe 34 is fixedly connected to the output end of the gas pump 33.
[0030] Filter plate 32 presents linear arrangement in the tank body 31, the top of the tank body 31 is fixedly connected with the side wall of the main frame 1, and the outer wall of the gas pipe 34 away from the gas pump 33 is fixedly connected with the outer wall of the main frame 1.
[0031] The outer wall of the pull frame 43 is slidably connected with the inner wall of the main frame 1, and the pull frame 43 penetrates through the main frame 1 and extends to the outside.
[0032] Working principle: when the carbon fiber composite material needs to be processed, inert gas is injected from the gas injection valve 8, and here the inert gas plays a role in protecting the pyrolysis process and preventing carbonization of the carbon fiber in the pyrolysis process.
[0033] The main frame 1 is mainly composed of a feeding mechanism 2, an inert gas recovery mechanism 3, a quick-release heating mechanism 4, a crushing mechanism 5, a discharge baffle 6, a discharge chute 7, and a gas injection valve 8. The carbon fiber composite material enters through the top of the feeding mechanism 2, is crushed by the crushing mechanism 5, and is accumulated in the main frame 1 after being heated. The composite material covering the surface of the carbon fiber is melted into waste gas by high temperature. At this time, the inert gas recovery mechanism 3 recovers the inert gas in the main frame 1, opens the discharge baffle 6, and the processed carbon fiber is discharged through the discharge chute 7.
[0034] The main structure of the feeding mechanism 2 includes a feeding baffle 21, a strip type sealing plate 22, and a compression spring 23. When the carbon fiber composite material needs to be processed, it enters from the top of the feeding mechanism 2 and the feeding baffle 21 opens downward due to gravity.

[0035] The main structure of the crushing mechanism 5 includes a motor 51 and a crushing roller 52.

[0036] The main structure of the inert gas recovery mechanism 3 is composed of a tank body 31, a filter plate 32, a gas pump 33, and a gas pipe 34. When the carbon fiber composite material is processed, the gas pump 33 starts to suck the contaminated inert gas in the main frame 1, which is filtered by the filter plate 32 in three stages, and then is transported back to the main frame 1 by the gas pump 33. When the filter plate 32 needs to be replaced, it can be directly taken out through the handle of the filter plate 32 for convenient replacement.
[0037] The main structure of the quick-release heating mechanism 4 includes a protection plate 41, an electric heating wire 42 and a pulling frame 43. When the carbon fiber composite material passes through the crushing mechanism 5, the protection plate 41 effectively protects the electric heating wire 42 from being damaged. When the quick-release heating mechanism 4 needs to be maintained, the pulling frame 43 can be directly taken out for maintenance through the handle.
