PURPOSE: A film winding wheel is provided to effectively use a wheel fitting the width of a film by controlling the gap in between a first holding fixture and a second holding fixture to fit the width of a corresponding film. CONSTITUTION: A film winding wheel includes a first holding fixture(10A), a second holding fixture(10B), a connector(20) and a nut(30). The first holding fixture and the second holding fixture have a shaft coupling hole(12a) to connect a rotary shaft on the center and a protrusion part(12b) on one side in a longitudinal direction. The first holding fixture and the second holding fixture are composed of a support pipe(12) formed with a male screw(12c) on the outside, multiple holding fixing parts(14) connected pipe in all directions to the projection part of the support, a fixing ring(16) installed on the end of the support part to fix the support and a reinforcing ring(18) attached to the outside of the support part to reinforce the fixing of the support part; and supports the sides of a wound film. A female screw(22) is formed on the bore of the connector in order to be connected to the male screw of the first holding fixture and the second holding fixture. A female screw(32) is formed on the bore of the nut to prevent the loose connection of the connector by being coupled with the male screw of the first and the second holding fixture and the outer circumference of the nut is formed with multiple coupling concave grooves(34). |
