20140346267 | WINDING DEVICE FOR A PE FILTER CORE - A winding device for a PE filter core includes a base pivotally provided thereon with a winding unit formed with a screw rod, and a material winding tube, which is short than the screw rod, is fitted around the screw rod. A driving unit is connected with the winding unit for both driving the screw rod and the material winding tube to rotate coaxially and reversely. By so designing, PE threads can be wound to form a PE filter core by the material winding tube, and the PE filter core can be removed from the material winding tube by the screw rod. Thus, PE filter cores can be produced quickly and incessantly. | 11-27-2014 |
