1 , bit by gluing phenomenon
　　 There are dirt on the rubber roller, such as paper scraps, starch agglomerates and other foreign matter, or foreign matter jams on the roller surface, which causes the rubber roller to not be glued smoothly, only a small amount of adhesive is transferred, and it is easy to be rubbed. Falling, when the glue is applied, there will be insufficient glue on the peak, and there will be intermittent glue on the spot. Such a corrugated cardboard surface will show signs of delamination of the face paper and the core paper, and the compressive strength, edge strength and adhesive strength of the carton will be reduced.
When the gap between the top roller and the lower corrugating roller is too wide, the applicator roller cannot contact the lower corrugating roller, and there is not enough adhesive on the corrugated peak.
2 , the lateral ejection of the adhesive phenomenon
　　 Adhesive viscosity is too high; too low or the borax content inside is too high, the adhesive will be laterally ejected when the line is running at high speed, which will cause the board to warp or the cardboard to be soft, the carton is bonded and pressed. And the compressive strength will be reduced.
3 , guide claw marks or vacuum traces
There are guide marks or vacuum marks on the sizing part. The carton made of corrugated cardboard usually breaks during use, and the edge strength of the corrugated board and the compressive strength of the carton are greatly reduced. Corrugated cardboard produced by a single-sided machine with a guide jaw often exhibits a guide paw mark (a clear blank without adhesive) in the sizing portion, usually mainly due to bending, wear, positional deviation or adjustment of the pressure guide flap. Large; the adhesive accumulates on the baffle and condenses into pieces, and the hardened starch rubs off the adhesive on the rubber roller to form a blank mark of the guide. In addition, the corrugated base paper has a high moisture content, and the wide adhesive on the squeegee or the sizing roller is wiped off by foreign matter due to wear on the sizing roller, which may cause this quality problem. Single-sided machines without guides often have vacuum marks on the sizing part, which is mainly caused by too much vacuum of the corrugating rolls. The vacuum will over-adhere the corrugated base paper to the corrugating rolls, causing the core paper to sag and the sizing roller not to The adhesive is applied to the peak of the depressed core paper.
4 , severely blurred intermittent sizing phenomenon
This phenomenon occurs before the rubberizing roller, mainly because the distance between the guide pawl and the corrugating roller is too large, the guide flap is damaged or worn, the moisture content of the corrugated base paper is high, the pressure on the pressure roller is uneven, and the corrugating roller There is dirt, loose brake on the core paper, uneven pressure on the corrugating roller or low pressure, no vacuum on the corrugating roller or no vacuum.
5 , irregular sizing shape
The irregular sizing shape is mainly caused by the unevenness of the corrugation caused by the inaccurate position when the guide claw and the core paper pass between the various rollers, the quality of the core paper, the dirt on the corrugating roller, the rough surface abrasion, the guide claw Wear, damage, bending, foreign matter on the guide claws, insufficient vacuum pressure of the guide claws or blockage of the vacuum holes, improper pressure on the pressure roller, too much or uneven brake tension on the core paper.
6. Insufficient or no adhesive bonding
If the viscosity of the adhesive is too low, the mesh of the rubberizing roller is clogged, and the gap between the rubberizing roller and the upper rubber roller is too small, the glue will be insufficient. The gap between the rubberizing roller and the corrugating roller is too large, and the vapor condensation drops on the rubberizing roller. The liquid level of the adhesive in the adhesive amount is too low, the contact between the lower corrugating roller and the pressure roller is poor, and the corrugating roller is high and the position is not Accuracy can lead to no adhesion.
7 , the adhesive over-glued
The excess of adhesive sizing is usually due to excessive gap between the sizing roller and the squeegee roll, or the adhesive viscosity is too high. Not only does it cause adhesive defects, but it can also cause problems with slab-like cardboard or paperboard warpage, and in the case of severe creases.
8. Effect of corrugating roller on sizing
There are depressions on the corrugated roller, dirt on the surface, damage or wear of the corrugated stick, uneven pressure on the corrugating roller, and non-parallel corrugation will affect the corrugation molding, which directly leads to poor sizing.
9 , poor sizing at the edge of the slit
The longitudinal edge of the corrugated board is not bonded to the corrugated core paper, and the loose paper phenomenon occurs. The main reason is that the slitting cutter is not sharp, the slitting machine is running at an excessive speed, the slitting knife overlaps too much, and the slitting edge is guided. Claw or vacuum marks, uneven moisture content at the edge of the paper, uneven corrugating roll abrasion caused by different paper webs, adhesive agglomeration on the pressure roller or lower corrugating roller.
