Problems solved by technology

[0004] In the prior art, the vacuum press shaft is used in the pressing process. The conventional vacuum press shaft is thrown out immediately after absorbing water. Although this method is simple, the effect of continuous water absorption is average, and the water removal will also affect the quality of the squeezed water. Cleaning of the external environment during the process

Abstract

The invention discloses a full-automatic vacuum squeezing device for producing high-strength corrugated base paper. The device comprises a heating press roll and a negative-pressure press roll, whichare movably attached to each other; a first rotating shaft is coaxially arranged in the heating press roll; the heating press roll is hollow, two ends of the heating press roll are rotationally connected with the first rotating shaft; a second rotating shaft is coaxially and rotationally arranged in the middle of the negative-pressure pressing roll; two sides of the periphery of the second rotating shaft are fixedly connected with the inner wall of the negative-pressure press roll through multiple sets of second supporting rods, the periphery of the second rotating shaft is movably sleeved with a vacuum negative pressure adsorption mechanism, the output end of the vacuum negative pressure adsorption mechanism and the heating press roll are continuously and oppositely arranged, and the first rotating shaft and the second rotating shaft synchronously and reversely rotate through a transmission mechanism. After the vacuum negative pressure adsorption mechanism is started, the heating press roll and the negative-pressure press roll are matched to press paper, so that water is efficiently removed, and the cleaning problem caused by water throwing of a traditional press device can be avoided by continuously keeping water absorption.

Description

technical field [0001] The invention relates to the technical field of corrugated paper processing, in particular to a fully automatic vacuum press device for producing high-strength corrugated base paper. Background technique [0002] Corrugated base paper is one of the important constituent materials for the production of corrugated cardboard. Corrugated base paper requires good fiber bonding strength, smooth paper surface, good tightness and stiffness, and requires a certain degree of elasticity to ensure that the made carton has shock resistance and pressure resistance. [0003] Pressing is an essential process in the paper forming process, and its main function is to remove part of the water in the wet paper and solidify the paper. How to quickly squeeze out the moisture in the wet paper, and how to store and remove it reasonably is a problem that must be considered and solved in the research of press dehydration. [0004] In the prior art, the vacuum press shaft is u...
