An automatic folder-gluer and a water-based glue sealing process based on the folder-gluer

Abstract

The invention provides an automatic box pasting machine used for an aqueous adhesive sealing process. The automatic box pasting machine at least comprises a machine base, a metal adhesive groove, a paper conveyor, a conveying platform, a pre-folding device and a press fit device, a temperature sensor is arranged inside the metal adhesive groove, the outer wall of the metal adhesive groove is provided with a layer of heat preservation and thermal insulation material, a heating element is arranged between the heat preservation and thermal insulation material and the outer wall of the metal adhesive groove, a transparent separation cover is arranged on the machine base and covers the press fit device and the conveying platform to separate the press fit device and the conveying platform from the exterior, and the transparent separation cover is provided with a hot air circulation system and a dehumidification device. The invention further provides the aqueous adhesive sealing process based on the automatic box pasting machine. The automatic box pasting machine overcomes the defects in the prior art, and the sealing efficiency, the sealing speed and the sealing quality are prevented from being affected by temperature and humidity in the working environment, especially the low temperature and high humidity environment through the automatic box pasting machine.

Description

technical field [0001] The invention provides an automatic folder-gluer, in particular to a folder-gluer using water-based glue for sealing, and also provides a water-based glue sealing process based on the folder-gluer, which belongs to the technical field of printing and packaging. Background technique [0002] Paper products made of paper products are widely used in all kinds of commodity packaging, which are closely related to human life and are products that need to be touched every day. Color printing paper products are square (or rectangular), and often need to be coated or coated with varnish on the paper after printing to become composite paper products that are paper-plastic composited or coated with varnish. These composite paper products are made into paper products It needs to be die-cut and indented by a die-cutting machine to become a semi-finished product, and then the "mouth" is firmly bonded with an adhesive to become a finished product package.

Problems solved by technology

[0012] 1. The hot-melt adhesive in the prior art belongs to the hot-melt cold-setting adhesive, which has excellent initial viscosity and fast viscosity in the molten state, fast curing speed, and also meets environmental protection requirements. Unfortunately, it can bond pure paper boxes (boxes) , bags) but it is extremely economically uneconomical, and it can also bond paper-plastic paper products, but the sealing cannot meet the requirements of high and low temperature resistance for a long time, and hot melt adhesives cannot stick to UV oil-paper products.

[0013] 2. The solvent-based oil-based adhesives in the prior art can also meet the quality requirements of initial tack and fast tack, but it is impossible to meet the standards of stickiness, temperature resistance, and environmental protection

[0018] 4. The nature of the materials bonded to each other restricts the working efficiency and speed of the existing fully automatic equipment: under the conditions of the working environment temperature above 25°C and the air humidity within 50%, the existing water-based sealing glue can only meet the requirements of pure Sealing speed requirements of 170-500 m / min for paper box (box, bag) products or 60-150 m / min for paper-plastic composite and UV oil box (box, bag) products

On the one hand, it is the only choice to use environmentally friendly water-based adhesives for commodity packaging used by human beings. On the other hand, the working methods of advanced equipment for pasting boxes (boxes, bags) in the prior art are not suitable for the application characteristics of water-based adhesives, resulting in the use of water-based adhesives in the most advanced technology. On the folder gluer, the use of the most advanced water-based adhesives can neither meet the full-load work requirements of advanced equipment, nor can it meet the most basic expectations of enterprises to produce with high efficiency, high quality and low cost throughout the year. Therefore, it is a strong expectation of the society, enterprises and users to solve the technical problems of the water-based glue sealing method of the folder-gluer of the prior art, and to improve the efficiency, quality and speed of the folder-gluer of the prior art when using water-based adhesives.
