A carton folding mechanism, a cover folding device and a carton sealing machine

By changing the guide rod of the carton sealing machine to a spiral shape and rotating it, combined with the cyclically rotating rear folding component, the problems of misalignment and deformation of the carton flaps in the carton sealing machine are solved, resulting in a smaller footprint and higher sealing efficiency.

AI Technical Summary

Technical Problem

The existing carton sealing machine's guiding and folding structure for the long carton flaps on both sides of the conveying direction of the packaging box easily causes the carton flaps to become misaligned and deformed. In addition, the guide rods arranged in a figure-eight shape are quite long and take up a lot of space.

Method used

The existing figure-eight shaped guide rods are replaced with symmetrically arranged spiral guide rods, which are connected to the rotating shaft via spokes or spokes. The rotating shaft is driven by a drive assembly, and the spiral guide rods fold the long box pages on both sides of the packaging box in the conveying direction. At the same time, the rear folding component is improved to a circulating rotating structure and driven by a servo motor to reduce vibration.

Benefits of technology

It effectively avoids misalignment and deformation of the carton pages, reduces the length occupied by the guide rod, improves the operational stability and sealing quality of the carton sealing machine, and reduces equipment costs.

Abstract

The utility model discloses a carton folding mechanism, folding device and carton sealing machine relates to packaging machinery technical field. The utility model discloses the two guide bars of existing eight -shaped arrangement are set to the spiral guide bar of symmetrical setting, and the spiral guide bar is connected on the rotating shaft through the spoke, drives rotating shaft rotation through the drive component, to drive spiral guide bar rotation, and the both sides long carton page of packaging box conveying direction are folded, realize the cover. The utility model on one hand can shorten the length of guide rod occupied, the guide rod of helical type produces two directions's rotation vector when rotating on the other hand, one vector is the vector of packaging box conveying direction, and the other vector is the vector of long carton page inward folding, compared with the mode that the existing guide rod adds resistance, the spiral rotatable guide rod adds to long carton page force more soft, effectively avoid the situation that the carton page produces the wrong side, the deformation, and the influence of long carton page deformation, box deformation is little, and the space is little.
