Problems solved by technology

Poorly bonded cardboard will block or stop other post-processing equipment, causing loss of production
However, the corrugated cardboard in the prior art has poor bonding, so it is necessary to provide a production method for corrugated cardboard with good bonding quality

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] figure 1 It is a flow chart of the production process of the present invention. Such as figure 1 Shown, corrugated paper production method of the present invention comprises the steps:

[0026] Step 1: Glue making;

[0027] (1) Inject 1150 parts of hot water at 28~32℃ into the mother tank, and add three kinds of additives (13 parts of strengthening agent first, then 5 parts of borax, and finally 3~5 parts of caustic soda) into the mother tank, Stir for 3~5 minutes;

[0028] (2) Add 300 parts of starch to the mother bucket while stirring, and stir for another 9 to 12 minutes;

[0029] (3) Add caustic soda solution with a caustic soda content of 7.5 parts to the mother bucket, stir for 15 minutes, and measure the paste viscosity with a 7# measuring cup to make it reach 27~29 seconds;

[0030] (4) Add 3.5~4.5kg of stabilizer, stir for 3~5 minutes, measure the...

Abstract

The invention provides a production method of a corrugated board. The production method comprises the following steps: step I, making glue; step II, preheating a corrugated medium, and then rolling the preheated corrugated medium by a corrugated roller to obtain corrugated paper; step III, preheating inside paper and face paper to be hung on a paper rack, sending the corrugated paper to a gluing machine for gluing through a transfer device, pressing the face paper and the inside paper on the corrugated paper, and mounting the corrugated board in the gluing machine; step IV, drying the corrugated board for sizing, and then cooling; step V, separating paper and pressing lines according to the required specification, and then cutting the corrugated board by a slitting machine and a crosscutting machine according to press lines; and step VI, stacking the cut corrugated boards, and storing the corrugated boards in a warehouse. Compared with the prior art, the production method has the following technical effects that the corrugated board prepared by the production method has a reasonable process design and low production cost. The gluing degree of the used glue in the production methodis high, the strength of the corrugated board is high, and the corrugated board has a good economic benefit and a good use effect.

Description

technical field [0001] The invention relates to the field of cardboard processing, in particular to a method for producing corrugated cardboard. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"). It has high mechanical strength and can withstand bumps and falls during handling. The actual performance of a corrugated box depends on three factors: the properties of the medium and paperboard and the construction of the box itself. [0003] Reliable bonding is necessary to form the corrugated cardboard frame and maintain its properties, and is also important to the quality of the final corrugated box packaging. Poorly bonded cardboard can block or shut down other post-processing equipment, causing losses...
