AI Technical Summary

Technical Problem

Existing cardboard printing equipment suffers from low conveying efficiency and requires operators to spend a lot of manpower and time when conveying heavy cardboard. Furthermore, the carrier plate cannot be tilted or adjusted, which affects printing efficiency.

Method used

A paperboard lifting mechanism for paperboard printing was designed. The first threaded rod in the drive box is threadedly connected to the movable frame and driven by a motor. The support column is hinged to the carrier plate. The slide and slider work with the electric cylinder to realize the stable lifting and tilting adjustment of the carrier plate. Rollers are set on the top of the carrier plate to reduce friction and adapt to different paperboard sizes and weights.

Benefits of technology

It enables stable and convenient paperboard conveying, reduces the labor intensity of operators, improves conveying and printing efficiency, is highly adaptable, has a compact structure, occupies little space, and is easy to install and maintain.

Abstract

The utility model discloses a paperboard lifting mechanism for paperboard printing, which comprises a bottom plate, and the top of the bottom plate is fixedly connected with a driving box. When the motor is adopted to drive the first threaded rod to rotate, the movable frame stably ascends or descends in the threaded direction, the supporting column moves up and down, and therefore the bearing plate is driven to achieve position adjustment in the vertical direction. By means of the structural design, the paperboard is evenly stressed in the lifting process, inclination or shaking is avoided, and the stability of the paperboard is guaranteed. When the electric cylinder pushes the sliding block to slide in the sliding groove, the connecting rod drives the bearing plate to rotate around the hinge point, the inclination angle of the bearing plate can be adjusted according to needs, paperboards can be smoothly conveyed to the surface of a conveyor, the paperboard conveying convenience and efficiency are improved, the paperboard printing efficiency is indirectly improved, and the whole lifting mechanism is compact in structure, small in occupied space and convenient to use. The device is convenient to install and maintain, is suitable for various paperboard printing production lines, and has the advantage of being good in lifting effect.
