A rewinding device after web cutting

Abstract

The invention discloses a roll inversing device after slitting of roll papers. The roll inversing device comprises a roll releasing machine, a main paper transmission roller, an air blowing pipe, a first front guide roller, a second front guide roller, a distance measuring sensor, a paper sucking platform, a pair of damping rollers, an air blowing roller and a rolling mechanism. The roll releasing machine includes a roll releasing shaft and a first variable frequency motor; the main paper transmission roller is driven through a second variable frequency motor; the air blowing pipe is mounted on the right lower side of the roll releasing machine; the first front guide roller and the second front guide roller are correspondingly mounted on the left and right sides of the air blowing pipe one to one by the same horizontal height; the distance measuring sensor is mounted rightly below the air blowing pipe; the paper sucking platform is mounted on the right side of the second front guide roller; the pair of damping rollers is mounted on the right side of the paper sucking platform; the air blowing roller is mounted below the main paper transmission roller; and the rolling mechanism includes a cylinder, a pair of linear guide rails, a slide base and a rolling shaft. The roll inversing device after slitting of the roll papers can effectively improve the end surface flatness of the roll papers, can largely reduce the manufacturing cost, and satisfies the product requirements.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a rewinding device after cutting a roll paper. Background technique [0002] The roll paper is the paper made by the paper machine, which is cut into a roll by a rewinder, and meets the national standard or the width and diameter of the user's requirements. However, the width of this kind of roll paper is relatively large, and multiple narrow-width finished products can be combined under this width, which requires a single finished product by slitting, and a single finished product is formed by rewinding after slitting. web. Since the current high-speed packaging machines have high requirements on the flatness of the end surface of the web, and the end surface of the web is often uneven during the cutting process, that is, the end surface of a single finished web after rewinding Uneven, does not meet the working requirements of the high-speed packaging machine. The reason for the unevenne...
