Problems solved by technology

In this way, the carton is the surface of the bobbin paper, and the appearance is very ugly, which seriously affects the appearance of the packaging carton. So I thought of bonding another layer of cardboard paper on the surface of the bobbin paper, but the bobbin paper and the carton paper are glued together. Since the two layers of paper are relatively thin, it is not easy to control the direct use of the current technology for bonding, and there will be many bubbles and wrinkles.
As a result, there are a lot of waste cardboards after bonding, and only by manual bonding, but the efficiency of manual bonding is very low.

Embodiment 1

[0016] A composite cardboard production process, comprising the following steps:

[0017] Such as figure 1 , figure 2 As shown, A, a roll of cardboard and a roll of bobbin are respectively placed on two rotatable horizontal shafts 6, and the bobbin and the bobbin are arranged one after the other;

[0018] B. Pull out the paper head of the boxboard paper roll, and pass over the upper rubber roller 2 of the sizing device, and the upper rubber roller 2 rolls to apply glue to the lower surface of the boxboard paper. Roller 2 and squeegee plate 3 are made up, and rubber groove 1 two ends side walls are supported by bearing to have upper rubber roller 2, and bearing is installed in the respective bearing seat of both sides. The lower part of the upper rubber roller 2 is located in the rubber groove 1, and the outer circumference of the upper rubber roller 2 is evenly opened with a ring groove 2a. The rubber plate 3 is composed of a scraper 3a and a cross bar 3b, the scraper 3a i...

Abstract

The invention discloses a production process of a composite cardboard. The production process comprises the following steps: pulling out the paper head of a cardboard paper scroll; coating glue on a gumming roller (2) of a glue-coating device so that glue is coated by gumming roller (2) on the cardboard paper in rows; passing the coated cardboard paper above scrolled bobbin paper; overlapping the cardboard paper and the bobbin paper to pass the same paper-guiding roller; gluing the lower surface of the cardboard paper and the upper surface of the bobbin paper; pasting the cardboard paper and the bobbin paper together; preheating and conveying the cardboard paper and the bobbin paper which are pasted together into a single-side corrugating machine; pasting at both sides of corrugated paper in the single-side corrugating machine; and thermal pressing and molding into a composite cardboard. The invention firstly gums and pastes the cardboard paper and the bobbin paper, thermally presses and molds with the corrugated paper without leaving bubbles or corrugation between the cardboard paper and the bobbin paper, has low defective rate of the finally molded the cardboard, improves the efficiency, can recycle glue scraped by a scraping gear and save the raw materials and the cost.

Description

technical field [0001] The invention belongs to the production process of cardboard, in particular, relates to a production process of composite cardboard. Background technique [0002] The general packaging cartons in China use corrugated paper as the cardboard. For some large electrical appliances, the cartons that only use corrugated paper as the cardboard are often not strong enough to meet the requirements of the transportation process. In the past, some wood was used to make the packaging box. However, using wood to make packing boxes consumes a lot of resources and does not meet the environmental protection requirements advocated by the state. [0003] At present, in order to make the packaging carton reach the required strength, a layer of bobbin paper is pasted on both sides of the corrugated paper, so that the required strength can be fully achieved. In this way, the carton is the surface of the bobbin paper, and the appearance is very ugly, which seriously affect...
