Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a dual-system veneer glue application method for carton production, which has the advantages of not being easy to open the glue and increasing the speed of the equipment, and solves the problem of the flow rate of the B and E cartons currently on the market during glue application. It is 23mm / S. In the process of gluing, because the glue is too thin, it is easy to cause quality problems of gluing, and the speed of the equipment is slow, which affects the production efficiency.

Embodiment 1

[0018] Embodiment 1: A double-system veneering and gluing method for carton production, comprising the following steps:

[0019] 1) import 880 kg of water in the rubber storage tank, then import 11 kg of rubber powder, add 160 kg of starch, and finally add 20 kg of caustic soda to obtain mixed solution A;

[0020] 2) Start the stirring device, stir the mixed solution A prepared in step 1), the stirring time is 3 minutes, and obtain the fully mixed solution B;

[0021] 3) Fermenting the mixed solution B prepared in step 2) at room temperature for 12 minutes to obtain the mixed solution C after fermentation;

[0022] 4) Add 11 kg of borax to the fermented mixed solution C obtained in step 3), then start the stirring device again, and the stirring time is 3 minutes to obtain the final glue;

[0023] 5) When producing E flute products, use a flow rate of 21mm / S. When switching to BC flute, just switch the glue formula directly on the hose system.

Embodiment 2

[0024] Embodiment 2: A double-system veneering and gluing method for carton production, comprising the following steps:

[0025] 1) import 1100 kg of water in the rubber storage barrel, then import 14 kg of rubber powder, add 200 kg of starch, and finally add 25 kg of caustic soda to obtain mixed solution A;

[0026] 2) Start the stirring device, stir the mixed solution A prepared in step 1), the stirring time is 5 minutes, and obtain the fully mixed solution B;

[0027] 3) Fermenting the mixed solution B prepared in step 2) at room temperature for 15 minutes to obtain the mixed solution C after fermentation;

[0028] 4) Add 14 kg of borax to the fermented mixed solution C obtained in step 3), then start the stirring device again, and the stirring time is 5 minutes to obtain the final glue;

[0029] 5) When producing E flute products, use a flow rate of 23mm / S. When switching to BC flute, just switch the glue formula directly on the hose system.

Embodiment 3

[0030] Embodiment 3: A double-system veneering and gluing method for carton production, comprising the following steps:

[0031] 1) import 990 kilograms of water in the rubber storage barrel, then import 12 kilograms of rubber powder, add 180 kilograms of starch, and finally add 22 kilograms of caustic soda to obtain mixed solution A;

[0032] 2) Start the stirring device, stir the mixed solution A prepared in step 1), the stirring time is 4 minutes, and obtain the fully mixed solution B;

[0033] 3) Fermenting the mixed solution B prepared in step 2) at room temperature for 13 minutes to obtain the mixed solution C after fermentation;

[0034] 4) Add 12 kg of borax to the fermented mixed solution C obtained in step 3), then start the stirring device again, and the stirring time is 4 minutes to obtain the final glue;

[0035] 5) When producing E flute products, use a flow rate of 22mm / S. When switching to BC flute, just switch the glue formula directly on the hose system.

Abstract

The invention relates to the technical field of carton gluing. The invention discloses a double-system veneering gluing method for carton production. The method comprises the following steps of (1) introducing 880-1100 kg of water into a glue storage barrel, then introducing 11-14 kg of glue powder into the glue storage barrel, adding 160-200 kg of starch, and finally adding 20-25 kg of caustic soda flakes to obtain a mixed solution A, and 2) starting a stirring device, and stirring the mixed solution A prepared in the step 1) for 3-5 minutes to obtain a fully mixed solution B. According to the double-system veneering gluing method for carton production, starch is added in the glue production process, starch is a polymeric carbohydrate, the polysaccharide is composed of a single type of sugar unit, the basic composition unit of the starch is alpha-D-glucopyranose, a covalent polymer formed by connecting glucose after water molecules are removed through glycosidic bonds is a starch molecule, the starch becomes turbid gradually after being placed in a thin paste state for a certain period of time, and finally insoluble white precipitate is generated.

Description

technical field [0001] The invention relates to the technical field of carton gluing, in particular to a double-system veneer gluing method for carton production. Background technique [0002] Carton is the most widely used packaging product. According to different materials, there are corrugated cartons and single-layer cardboard boxes, etc., with various specifications and models. Cartons are commonly used with three layers, five layers and seven layers. Seven layers are less used. The layers are divided into lining paper, corrugated paper, core paper and surface paper. The lining paper or surface paper includes tea board paper and kraft paper, and the core paper uses corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers is also different. , usually used as a wrapper for the product or the outer layer of the product to protect the product. The volume of the carton changes due to the size of the product. The ...
