A feeding system includes a hopper, a high-pressure fan, a filter, a controller, and a receiving box. The hopper is filled with plastic material. The controller is connected with the high-pressure fan and the filter. The high-pressure fan, the filter, and the controller are received in the receiving box. The filter is connected to the hopper via a feeding pipe. The high-pressure fan is connected to the feeding pipe. The controller controls the high-pressure fan to generate a pulling force to pull the plastic materials out of the hopper, and controls the filter to filter the plastic material.
