Electric feeding mechanism is used to doffer

The utility model belongs to the technical field of the doffer and specifically relates to an electric feeding mechanism is used to doffer. It includes: trachea and cable, the cable is worn to adorn in the trachea, tracheal internal diameter is greater than the external diameter of cable, press from both sides regional air flue for being used for the air feed to pass through between trachea and the cable. It utilizes the not wear resistant cable of wear resistant trachea protection, has avoided the wearing and tearing of cable, has reduced manufacturing cost, the problem of having avoided conflagration that the electric leakage led to the fact and workman to get an electric shock, and trachea wearing and tearing back, because gas leakage has sound likely to suffer from existing, and gas leakage compares the electric leakage and can not lead to the fact bad consequence, makes things convenient for the timely break -down maintenance of workman, utilizes indirect mode thoroughly to solve the problem of electric
