A lifting platform 5, which is correspondingly arranged at the middle position of the film-wrapping chain plate machine 1;

The mounting frame 6 is fixedly mounted on the outer side of the coating chain plate machine 1, and the guide rails 7 are symmetrically fixed on the left and right sides of the upper surface of the mounting frame 6, and the outer part of the guide rails 7 is fitted with a guide slider 8, and the upper surface of the guide slider 8 is fixedly mounted with a support column 9, and the upper part of the support column 9 is connected through a centering adjustment rod 10.

In this example, 5 groups of reflective photoelectric switches 3 and reflective plates 4 are arranged transversely on the sides of the film-wrapping chain plate machine 1, and the reflective photoelectric switches 3 and reflective plates 4 are distributed front and back in correspondence; the reflective photoelectric switches 3 and reflective plates 4 at the middle position of the lifting platform 5 correspond front and back, and the reflective photoelectric switches 3 at the second and fourth positions are respectively arranged on the left and right sides of the lifting platform 5;

The paper roll is set on the film wrapping chain plate machine 1 and transmitted from left to right. During the transmission process, the five groups of reflective photoelectric switches 3 and reflective plates 4 installed at the frame of the film wrapping chain plate machine 1 can detect the transmission and movement position of the paper roll. When the reflective photoelectric switch 3 at the middle position detects the paper roll, the reflective photoelectric switches 3 at the second and fourth positions do not detect the paper roll. At this time, the paper roll is in the center position of the workstation, and the paper roll can directly proceed to the next step of film wrapping processing. If the reflective photoelectric switch 3 at the second or fourth position detects the paper roll, the processing position of the paper roll is offset at this time, and it is necessary to correct its processing position before film wrapping processing.

When the detected paper roll processing position is offset, the electric lifting rod 12 is controlled to operate, and the electric lifting rod 12 controls the driving cross bar 13 to move downward. The side of the driving cross bar 13 drives the centering adjustment rod 10 to move downward synchronously through the transmission side rod 11, and the bottom of the centering adjustment rod 10 passes through the inside of the supporting column 9 and slides downward.

At this time, the two ends of the limit pull rod 15 connected to the side of the positioning plate 14 rotate, and the limit pull rod 15 controls the support column 9 to move horizontally. The guide slider 8 below the support column 9 is engaged with the upper side of the guide slide rail 7 and slides horizontally. This part of the transmission structure can control the centering adjustment rods 10 on the left and right sides to move inward synchronously while moving downward. The centering adjustment rods 10 on the left and right sides move downward gradually with the side of the paper roll, pushing the paper roll to the center at the film wrapping station, correcting the processing position of the paper roll, and improving the accuracy of paper roll film wrapping.
