Embodiment 1

[0031] The creasing softening process for carton printing includes the following steps:

[0032] 1) Place the cardboard for manufacturing the carton;

[0033] 2) The pressing wheel 8 is in contact with the cardboard placed below, and the cardboard is transported along the track of the pressing line;

[0034] 3) While conveying, the nozzle 11 splits and sprays out the softener to wet and soften the cardboard;

[0035] 4) Set the working temperature through the operation panel;

[0036] 5) air-drying, air-drying the cardboard softened by the softener, and controlling the moisture content to 7%-10%.

[0037] The softener includes components in parts by weight: 30-40 parts of water, 6-10 parts of sodium alkylsulfonate, 10-15 parts of sodium alginate, 10-15 parts of acrylic acid, 2-5 parts of oxalic acid, 8-16 parts 10-25 parts of water-based polyurethane, sodium polyacrylate, 5-20 parts of hexanediol, 2-5 parts of sodium stearate; 10-30 parts of sodium hydroxide; 10-30 parts of...

Abstract

The invention provides a crimping line softening process for carton printing, which uses the crimping line softening equipment for carton printing to soften the cardboard to be treated, comprising the following steps: 1. Place the cardboard for making the carton; 2. The placed cardboard touches, and the cardboard is transported along the track of the creasing line; 3. At the same time of transmission, the nozzle sprays out the softener to wet and soften the cardboard; 4. Set the working temperature through the operation panel; 5. Air dry, Carry out air-drying operation to the cardboard softened by the softener, and control the moisture content to 7%-10%. The invention has the characteristics of simple structure and convenient creasing process.

Description

technical field [0001] The invention relates to the technical field of printing press line softening, in particular to a press line softening process for carton printing. Background technique [0002] Carton is a common packaging material. During the production process, it is necessary to soften the cardboard to obtain folding marks so as to facilitate subsequent assembly and molding operations. It is often processed by softening equipment. When the traditional crimping and softening equipment is in use, it does not provide a rotating guide for the crimping parts, which cannot ensure that the creasing operation is carried out on a fixed track, which affects the accuracy of the creasing process. At the same time, the softening quality of the cardboard is not good, which affects The use of crimping and softening equipment. [0003] To sum up, in order to solve the shortcomings of the existing carton printing softening technology, the present invention designs a creasing softe...
