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 technical...

Abstract

The invention provides a heating method and a heating device for corrugated cardboard before bonding, which can solve the problem in the prior art that the heating temperature far away from the heating source is not enough and the bonding effect is poor. The technical solution is a heating method before bonding corrugated boards. After a plurality of single-sided corrugated papers are glued by a gluing machine, before entering the double-sided machine for bonding, the middle paper in the multiple single-faced corrugated papers is heated by a heating device. direct heat. In the present invention, the heating medium is directly sprayed on the surface of the middle paper of the single-sided corrugated cardboard, so that the upper surface of the middle layer of single-sided corrugated cardboard can be heated rapidly. Paste the glue more quickly and fit well to meet the high-speed and high-quality requirements of the corrugated cardboard production line.

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...
