AI Technical Summary

Technical Problem

The existing paper lamination machine pressure-free paper feeding mechanism can easily cause cardboard to shift when conveying cardboard, affecting subsequent processing work.

Method used

A paper lamination machine pressure-free paper feeding mechanism is designed, and the cardboard conveying is carried out by combining a vacuum nozzle and a limiting mechanism. The vacuum nozzle absorbs the cardboard through vacuum to avoid damage to the strength of the paper structure by traditional pressure conveying; the limiting mechanism ensures that the cardboard will not be offset during the conveying process through the cooperation of the bidirectional screw and the push plate.

Benefits of technology

It effectively avoids the deviation of cardboard during the conveying process, improves the stability and comprehensiveness of conveying, and protects the structural strength of the paper.

Abstract

The invention discloses a pressure-free paper feeding mechanism of a paper mounting machine and belongs to the technical field of paper product conveying equipment. The device comprises a shell, a first sliding groove is formed in the top of the shell, an adsorption mechanism is arranged on the inner wall of the first sliding groove, a second sliding groove is formed in the bottom of the first sliding groove in a penetrating mode, a conveying belt is fixedly installed in the shell, and the adsorption mechanism comprises a reciprocating frame and a vacuum suction nozzle. A paperboard can be adsorbed through a vacuum suction nozzle, the damage of traditional pressure conveying to the structural strength of the paperboard is avoided, a limiting mechanism is arranged on the side wall of the shell so that the conveying path of the paperboard can be limited during conveying, and a shaking mechanism is arranged in the shell so that when the vacuum suction nozzle adsorbs the paperboard, the shaking mechanism can shake the paperboard in the conveying path of the paperboard. And paperboards which are not conveyed can be tidied. The spring drives the fixing rod to move downwards, the inclined face of the abutting block extrudes the second limiting plate, the falling paperboard is guided and limited through outward rotation of the torsional spring hinge, and stable conveying is guaranteed.
