Paperboard pretreatment device for corrugated paper forming

Abstract

The invention relates to the technical field of corrugated cartons, and discloses a paperboard pretreatment device for corrugated paper forming. The paperboard pretreatment device comprises a glue boxcasing; a positive plate is fixedly connected to the inner wall of the glue box casing; a screw rod is in threaded connection in the position, close to the right side of the positive plate, of the inner wall of the glue box casing; a dielectric plate is movably connected to the bottom of the screw rod; and a negative plate is fixedly connected in the position, close to the right side of the dielectric plate, of the inner wall of the glue box casing. According to the paperboard pretreatment device for corrugated paper forming, the glue outlet amount of a glue box is controlled through the electromagnetic principle, glue in the glue box can be sprayed out completely and conveniently during glue spraying, residues on the inner wall of the glue box are avoided, resource waste is prevented, the glue box is prevented from being blocked during intermittent use, and the service life of the glue box is prolonged; and the glue outlet amount is convenient to control, the phenomenon of uneven glue outlet is avoided, uneven glue amount routing on a corrugated paperboard is prevented, and the percent of pass of products is increased.

Description

technical field [0001] The invention relates to the technical field of corrugated paper boxes, in particular to a cardboard pretreatment device for forming corrugated paper. Background technique [0002] Corrugated boxes are assembled and spliced ​​by a plurality of corrugated cardboards. Before the corrugated boxes are formed, the corrugated cardboards need to be glued. Most of the existing gluing machines are self-flowing during the gluing process. During gluing, it is difficult to spray out all the colloid in the glue box, and there will be residues on the inner wall, and the amount of glue is not easy to control during the glue spraying process, and there will be uneven spraying, and the amount of glue required by different corrugated boards is also different. [0003] When the existing corrugated cardboard gluing machine is in use, it is necessary to manually open the valve in the glue box, and it is difficult to spray out all the glue in the glue box when spraying glue...

Problems solved by technology

[0002] Corrugated boxes are assembled and spliced ​​by a plurality of corrugated cardboards. Before the corrugated boxes are formed, the corrugated cardboards need to be glued. Most of the existing gluing machines are self-flowing during the gluing process. When gluing, it is difficult to spray out all the colloid in the glue box, and there will be residues on the inner wall, and the amount of glue is not easy to control during the glue spraying process, and there will be uneven spraying, and the amount of glue required by different corrugated cardboards is also different.

[0003] When the existing corrugated cardboard gluing machine is in use, it is necessary to manually open the valve in the glue box, and it is difficult to spray out all the glue in the glue box when spraying glue, and there will be residues on the inner wall of the glue box, which will cause waste of resources and interruption. When used, it will cause blockage of the plastic box, reduce the service life of the plastic box, and the size of the glue output is not easy to control, and there will be uneven glue output, resulting in uneven glue on the corrugated cardboard, reducing the qualification of the product At the same time, the glue output of the glue box is not easy to control, and the limitations of use are large.
