Pretreatment device for production of polymer rubber material

According to the technical scheme, the pretreatment device comprises a shell, a barrel is arranged at one end of the shell, a supporting plate and a supporting rod are arranged at the end, away from the shell, of the barrel, the supporting rod is fixedly connected with the barrel, and the supporting rod penetrates through the middle of the supporting plate and is in sliding connection with the supporting plate; the pretreatment device comprises a shell, a crushing mechanism is arranged in the shell, the crushing mechanism comprises a mounting frame, a motor and a fixing plate, the mounting frame is fixedly connected with the inner wall of the shell, and the motor is fixedly mounted at the top of the mounting frame. The transmission rod and the multiple cutting knives are driven to rotate, meanwhile, the barrel body is driven to slide on the two supporting tables in a reciprocating mode, so that internal powder balls can be fully smashed, operation is easy, practicability is high, and the problems that most ex
