AI Technical Summary

Technical Problem

Existing conveying devices are not convenient for adjusting the spacing of guide rollers for different widths of cardboard. This causes narrow cardboard to sway and deviate easily during transport, while wide cardboard is squeezed and wrinkled due to the small spacing, affecting the stability of the transport and the quality of the cardboard.

Method used

An adjustment mechanism and a guiding mechanism were designed. The adjustment mechanism adjusts the spacing between the guide rollers by driving the connecting rod and the moving plate with a motor. The guiding mechanism uses a spring telescopic rod and a rotating shaft to reduce friction and adapt to different cardboard specifications and shapes.

Benefits of technology

It ensures the stability and quality of cardboard during transport, avoids shaking, shifting, and squeezing, improves transport efficiency and overall system efficiency, and adapts to the needs of multi-batch production.

Abstract

This utility model discloses a cardboard conveying device for packaging box processing, relating to the technical field of conveying devices. The utility model includes two support frames, each with an adjustment mechanism and a guiding mechanism. The adjustment mechanism includes rectangular support plates fixedly connected to the inner walls of the two support frames, with a second support frame fixedly connected to the bottom of each rectangular support plate. A second motor is fixedly connected to the bottom of the second support frame. The guiding mechanism includes two third support frames positioned above the first support frames, each containing a fourth support frame. By incorporating the adjustment mechanism, this utility model solves the problem in existing conveying devices where adjusting the guide roller spacing for cardboard of different widths is inconvenient. This leads to narrow cardboard easily swaying and shifting during transport, while wide cardboard is squeezed and wrinkled due to insufficient spacing, severely affecting conveying stability and cardboard quality.
