AI Technical Summary

Technical Problem

Existing cardboard conveying devices cannot effectively limit cardboard of different thicknesses, which makes the cardboard easy to deviate during the conveying process, and the conveying efficiency is low, and the fit between the cardboard and the conveying device is poor.

Method used

The system employs an airbag and limiting wheel system. The airbag adjusts the elastic fit between the limiting wheel and the cardboard, and the screw adjusts the height of the limiting wheel, thus achieving flexible limiting and stable conveying of cardboard of different thicknesses.

Benefits of technology

It enables stable conveying of cardboard of different thicknesses, improves transmission efficiency and protection, avoids damage caused by rigid bonding, and enhances friction and stability.

Abstract

The utility model discloses a paperboard transmission device is used in packing carton processing, include: conveyer, the inside rotation of conveyer is connected with conveyer belt, the top right -hand member fixed connection of conveyer has fixed frame, auxiliary assembly, the auxiliary assembly includes screw rod. The utility model discloses, through pressing air bag can make outside air through telescopic pipe from the air inlet pipe into the inside of sleeve, when the gas in the sleeve enters the air pressure and rises, the piston rod will be subjected to the reverse thrust and make the sliding frame push the limit wheel always with the outside elastic of paperboard and fit, further can make paperboard and conveyer belt between the close contact and improve the friction, realize the purpose of stable conveying can also avoid the limit wheel and paperboard rigidly and fit, improve the protection of paperboard, and through the rotation screw rod can make it along the internal thread of fixed frame and lift, further can realize the height of adjusting limit wheel, finally realize the flexible limit of paperboard of different thickness, the effect of stable conveying.
