The invention discloses a pushing mechanism for a winding former, comprising a cylinder fixed on a motor bearing. The cylinder is connected with a coupling lever which is fixed on the upper surface of the motor bearing through a base, the coupling lever is connected with a pushing plate, and the surface of the pushing plate is provided with a rubber layer. When a winding working procedure is finished, a winding layer with a certain thickness is formed on the winding former, the coupling lever drives the pushing plate to horizontally and slowly move and lean against the winding layer under the powder-driven action of the cylinder, the winding layer is pushed and move backward together with the winding former, therefore, the purpose of separating the winding former and a rotary fixed hinge pin arranged on a motor is achieved. The invention has stable and reliable operation, improves the production efficiency and saves the manpower, and even more important, the invention improves the production safety and reduces the possibility of occurrence of accidents.
