Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: a film winding device comprises a winding roller 1, a winding roller 2, a fixing rod 3 and a flattening roller 4, wherein the winding roller 2 is fixedly arranged on the winding roller 1, the fixing rod 3 is positioned above the winding roller 1, two groups of brackets 5 are fixedly connected onto the fixing rod 3, two ends of the flattening roller 4 are rotatably connected with the brackets 5, the fixing rod 3 is positioned obliquely above the winding roller 1 and is connected with the flattening roller 4 through the brackets 5, the end part of each bracket 5 is rotatably arranged on the fixing rod 3, the flattening roller 4 is attached to the winding roller 2 under the action of self gravity, as shown in figure 1, the fixing rod is attached to a film on the winding roller 2 only under the action of the self gravity and rotates and flattens along with the rotation of the film, two ends of the flattening roller 4 are both connected with driving cylinders 6, the outer diameter of each driving cylinder 6 is the same as that of the flattening roller 4, two groups of annular air bags 7 in contact with the winding roller 6 are arranged on the winding roller 1, the annular air bag 7 is arranged, can be continuously expanded outwards along with the position change of the flattening roller and is always in contact with the transmission cylinder 6, the outer diameter of the transmission cylinder 6 is the same as that of the flattening roller 4, so that the transmission cylinder 6 is driven by the air bag 7 to rotate and is driven by the film, and the outer surface of the air bag can be set into a surface with larger roughness to keep a relatively static state with the contact surface of the transmission cylinder 6, and cannot slide relatively, so that scratches cannot be generated on the surface of the film.

The inner side of the air bag 7 is fixedly connected with a fixing ring 8 and is arranged on the wind-up roll 1 through the fixing ring 8, the fixing ring 8 is positioned at the axial symmetrical center position of the air bag 7, the purpose of arranging the fixing ring 8 is to keep the contraction change of the two ends of the air bag 7 to be the same, because the position of the fixing ring 8 is positioned in the middle, the roll-shaped diameter formed by the fixing ring is larger and larger along with the rolling of the film, the flattening roll 4 is pushed, the air bag 7 is shortened in the axial direction due to the change of the pressure of the flattening roll 4 to be larger in the radial direction, so that the driving cylinder 6 is always attached, the fixing ring 8 is more convenient to fix, the end part in the wind-up roll 1 is provided with an air pipe 9, the end part of the air pipe 9 is connected with the fixing ring 8 and extends into the air bag 7, because the air bag 7 is changed under the pressure of the flattening roll 4 and is possibly not stable, and the air pipe 9 is arranged to be connected with an air pressure stabilizing mechanism to make the air pressure stably change, thereby better driving.

The mounted position of gasbag 7 is located the both ends of wind-up roll 1, and wind-up roll 1 itself divide into two parts, and partly be detachable part, and the part at both ends is fixed on the rolling machine, because wind-up roll 1 need be convenient receive reel 2 from top to bottom, consequently its mid portion can be dismantled, and still because different customers are different to the width demand of film, consequently its length of receiving reel 2 also just also is different, does not influence the dismantlement and the installation of receiving reel 2 with its setting in the non-detachable part of tip.

The both ends of nip roll 4 can be dismantled and be connected with telescopic link 10, driving cylinder 6 is connected on telescopic link 10, and the convenience of telescopic link 10 corresponds the position of adjustment driving cylinder 6 according to the length of winding drum 2, and telescopic link 10 can be dismantled and connect in the tip of nip roll 4.
