Cardboard ornamental packaging boxes corner warpage is a very difficult problem for many carton packaging enterprises. ornamental packaging boxes cardboard corner warpage will bring many disadvantages to the enterprise, such as increased labor intensity of workers, increased scrap rate, the normal use of automated machines, affecting productivity, etc.. Therefore, it is necessary to find out the causes of corner warping of ornamental packaging boxes and give countermeasures for improvement.
ornament packaging boxes diagonal warpage is the warpage generated by the synthesis of longitudinal and transverse warpage. The cause is mainly in ornament packaging boxes on one side of the corrugated board stacked too much overload, single-sided corrugated board on the tension is too large (tension is the cause of the longitudinal warpage). In addition, ornamental packaging boxes warp up, warp down or S-shaped warpage is caused by the moisture difference of the corrugated board that disrupts the balance of expansion and contraction. Therefore, in order to solve the ornamental packaging boxes diagonal warpage, we should start from the above three situations and give the countermeasures to improve the ornamental packaging boxes diagonal warpage one by one.
When ornamental packaging boxes paper moisture uneven, it is necessary to solve the moisture problem, many companies will choose to ornamental packaging boxes cardboard to increase the cover, the cardboard moisture drying, in ornamental packaging boxes production, so that the moisture error is small, but the paper fiber damage will be large. But the destruction of paper fibers will be large, will lead to ornamental packaging boxes cardboard physical indicators data decline, to solve ornamental packaging boxes moisture unevenly recommended to spray to increase the paper moisture, drying through the pre-heater to balance the moisture content of the paper.
Tension control on ornamental packaging boxes cardboard bending is still relatively large impact, uneven tension or tension too tight and too loose will cause ornamental packaging boxes cardboard bending. In the production process to control the tension, ornamental packaging boxes tension tight on behalf of the paper and pre-heater friction increased and tightness, the heat on the paper will increase will have an impact ornamental packaging boxes cardboard flatness, loose on the opposite heat is small, followed by ornamental packaging boxes tension unevenly leading to uneven paper tension and paper unevenly heated to lead to changes in cardboard moisture temperature difference, the formation of ornamental packaging boxes bending.
Too much paper accumulation on the bridge, then ornamental packaging boxes tension will increase, in the single tile lato, easy to form inverted fluting phenomenon and single tile extrusion on the bridge for a long time, the temperature and moisture evaporation, resulting in ornamental packaging boxes moisture is too low, then it will have an effect on ornamental packaging boxes cardboard bonding impact, while because of the tension gap, resulting in ornamental packaging boxes paper bending.
Ornamental packaging boxes cardboard corner warpage causes and improve countermeasures have a comprehensive understanding, I believe that in the future production of ornamental packaging boxes, ornamental packaging boxes corner warpage problem can easily be handled, so ornamental packaging boxes packaging boxes cardboard flat to no friend!
