The utility model relates to a traction rotating structure on a large blown film machine. Involving the equipment and mechanism of large-scale film blowing machines. The advantage lies in. Improve the operational stability of traditional rotating mechanisms. Reduce the lateral fluctuation deviation of the film. Simplify traditional rotating structures. Improve the degree of automation. Easy to operate. Save manual labor.
The structure is as follows. The S1 rotary turntable is equipped with a circular iron plate. Install the traction frame S2 on the circular iron plate, and rotate the mechanism S3-360 degrees back and forth. Install traction roller S3 on traction frame S2. The traction roller adopts a three roller structure. Resolve large wide width equipment. Rubber roller compression deformation. There is a gap phenomenon in the middle. Install the center point on the upper side of the top of the towing frame. The horizontal rotating gear mechanism S4 is equipped with a star shaped gear that meshes with the main shaft and rotates back and forth 180 degrees with the large gear. There are two air floating rods S5 that support the film at opposite angles. Operate horizontally with the toothed disc, with half of the circumferential surface of the air floating rod. Equipped with array micro holes. Install vortex air pumps at both ends. Used to reduce the friction coefficient of thin films. A triangular support frame S6 is installed between two air floating rods. Install guide aluminum rods and flattening rods. Install a herringbone plate gantry bracket S7 below S1. Equipped with an electrically adjustable herringbone plate opening and closing mechanism S8. Auxiliary herringbone plates S9 are installed on both sides of the herringbone plate to improve the stability of film bubble blowing.
