Description

Technical Field

[0001] The utility model relates to the technical field of back pressure devices, and more specifically, to an aluminized paper back pressure device. Background Art

[0002] Aluminum-coated paper is usually wrapped around paper tubes during storage and transportation. However, since the aluminum-coated paper is wrapped around the paper tubes for a long time, the aluminum-coated paper will form a certain curvature, that is, the flatness is poor. When the aluminum-coated paper is directly put into the processing process, the curved surface of the aluminum-coated paper can easily cause errors in the processing process, which in turn leads to unqualified product quality. At present, a back-pressure device is used to flatten the aluminum-coated paper, but the existing back-pressure device is generally provided with three guide rollers. First, the inner side of the aluminum-coated paper is laminated with one of the guide rollers, and then the aluminum-coated paper is passed around the second guide roller, and the outer side of the aluminum-coated paper is laminated with the second guide roller. Then, the aluminum-coated paper is passed around the third guide roller, and the inner side of the aluminum-coated paper is laminated with the third guide roller. The aluminum-coated paper forms a V-shape at the three guide rollers. The back-pressure on the aluminum-coated paper is achieved by the second guide roller, which reduces or even eliminates the curvature of the aluminum-coated paper. However, when the aluminum-coated paper is wrapped around the paper tube, the closer it is to the center of the paper tube, the smaller the curvature of the aluminum-coated paper is. The larger the arc of the aluminized paper at the center, the smaller the arc of the aluminized paper closer to the edge of the paper tube. When the back-pressure arc between the three guide rollers is large, it is easy to over-press the aluminized paper at the edge of the paper tube and cause the aluminized paper to bend in the opposite direction. When the back-pressure arc between the three guide rollers is small, it is easy to over-press the aluminized paper at the center of the paper tube and cause the back-pressure strength to be too small, resulting in poor back-pressure effect. In addition, some paper tubes are not equipped with a rolling device when unwinding, resulting in the aluminized paper not being in a straight state during the unwinding process, which also leads to poor back-pressure effect.
