When being put into the connecting cylinder 4, in order to reduce the influence of the hot air at the lower end on the plastic raw materials, the hot air is extracted from the connecting cylinder 4 through the air extraction mechanism, thereby reducing the influence of the hot air on the plastic raw materials.
