AI Technical Summary

Technical Problem

Existing box-closing equipment is difficult to adapt to different specifications and models of boxes, and the top cover is prone to shifting or tilting during the closing process, resulting in a high failure rate and affecting efficiency and quality.

Method used

The system employs a lifting assembly combined with a bottom box clamping assembly and a top cover guide assembly. A servo motor drives a lead screw and nut structure to achieve bottom box height adjustment and stable clamping. The guide plate spacing is adjusted by a slide cylinder to ensure that the top cover is accurately inserted into the bottom box slot.

Benefits of technology

It enables flexible adaptation to packaging boxes of different specifications, reduces the risk of sealing errors, improves sealing accuracy and efficiency, reduces manual intervention, and is suitable for large-scale production.

Abstract

This utility model discloses a packaging box closing device, belonging to the packaging field. The device includes a base plate, a lifting assembly, a bottom box placement seat, a bottom box clamping assembly, a top cover placement seat, a top cover guide assembly, and a push-lid assembly. The lifting assembly, top cover placement seat, top cover guide assembly, and push-lid assembly are fixed to the top of the base plate. The lifting end of the lifting assembly is fixed to the bottom box placement seat. The top cover placement seat and the bottom box placement seat are arranged opposite each other. The bottom box clamping assembly is disposed on the bottom box placement seat. The top cover placement seat has a push-lid channel in the middle. The push-lid end of the push-lid assembly extends into the push-lid channel to push the top cover towards the bottom box. The guide end of the top cover guide assembly extends above the push-lid channel. This utility model, through the height adjustment function of the lifting assembly and the stable clamping of bottom boxes of different specifications by the bottom box clamping assembly, allows the device to flexibly handle packaging boxes of various sizes and models, solving the problem of limited adaptability of traditional equipment.
