Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] see figure 2 In order to overcome the existing problems of heat transfer layer by layer in the existing heating method, the method of the present invention is to provide a heating device 4 at the position before entering the double-sided machine 7 after the gluing machine 2, and the heating device 4 only heats the single side. The middle paper in the corrugated paper is directly heated. In this way, before entering the double-facer, the middle paper is heated to make it preheated, and then enters the double-facer and is heated by the hot plate of the double-facer, so that the overall temperature of the corrugated cardboard is balanced and the bonding effect is guaranteed. It overcomes the problem in the prior art that the bonding effect of the part far away from the hot plate of the double-sided machine is not good.

[0038] As far as the specific technica...

Abstract

The invention provides a heating method and device before corrugated paperboard adhesion and solves the problem that parts away from a heating source are insufficient in heating temperature, and adhering effect is poor in the prior art. According to the technical scheme, the method includes: the heating device is used to directly heat the middle paper of multiple single-side corrugated paper after the single-side corrugated paper is coated with adhesives through a adhesive coating machine and before the single-side corrugated paper enters a two-side machine to adhesion. The method has the advantages that medium is directly sprayed on the middle paper surface of the single-side corrugated paper to allow the upper surface of the middle-layer single-side corrugated paper to be heated fast, when the upper surface is in contact with the corrugated paper tips coated with adhesives, the adhesives can be pasted fast, good adhesion effect can be achieved, and the requirements of corrugated paperboard production line high speed and quality can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to a gluing machine and a double-facer of a corrugated cardboard production line in the corrugated packaging machine, and is a method for heating the corrugated cardboard used in the production of corrugated cardboard. Background technique [0002] The gluing machine is a device located between the single-facer corrugating machine and the double-facer machine. It evenly coats the edge of the single-face corrugated cardboard produced by the single-facer corrugating machine with a thin layer of glue, and then enters the double-facer machine and another Layers of single-sided corrugated paper or face paper bonding. During the bonding process, the glue must be heated to gelatinize the glue, so that the bonding of the cardboard can be firmly bonded. Heating temperature directly affects the quality of corrugated cardboard. [0003] figure 1 It is a schematic di...
