AI Technical Summary

Technical Problem

When using elastic films, it is difficult for existing laser die-cutters to accurately correct the stretching situations occurring on one side, resulting in low die-cutting efficiency, short equipment life, and may interfere with the normal conveying of the film when it is not corrected.

Method used

A bias correction roller including a rotating shaft, a cylinder, a movable arc block and a fixed arc block is designed. The deviation correction is achieved through the lifting of the movable arc block, and combined with the image acquisition and processing device and a bias correction guide frame, the precise deviation correction of the elastic film is achieved.

Benefits of technology

It realizes accurate correction of the stretching condition of one side of the elastic film, improves the die-cutting efficiency and equipment service life, and does not interfere with the normal conveying of the film when it is not corrected.

Abstract

The invention belongs to the technical field of packaging equipment, and relates to a laser die-cutting machine convenient for deviation rectification, which comprises a deviation rectification device, a deviation rectification roller of the deviation rectification device comprises a rotating shaft, a cylinder, a plurality of movable arc-shaped blocks and a plurality of fixed arc-shaped blocks, and the plurality of movable arc-shaped blocks and the plurality of fixed arc-shaped blocks are uniformly arranged on the peripheral surface of the cylinder at intervals; the outer side surfaces of the multiple fixed arc-shaped blocks are spatially located on the same cylindrical surface so as to be used for conveying the elastic film, the height of the outer surfaces of the multiple movable arc-shaped blocks arranged between the fixed arc-shaped blocks at intervals is smaller than the height of the fixed arc-shaped blocks in the radial direction of the cylinder, and when deviation correction needs to be conducted, one end of each movable arc-shaped block is lifted, and the other end of each movable arc-shaped block is lifted; the height of the outer surface of the movable arc-shaped block is higher than that of the fixed arc-shaped block in the radial direction of the cylinder, and the sizes of the two ends of the deviation rectifying roller are changed. According to the laser die-cutting machine, deviation correction can be conducted when one side of the elastic film is stretched, and meanwhile normal conveying of the elastic film cannot be disturbed when deviation correction is not conducted.
