The influencing factors on the quality of the cardboard barrels and solution

Publish: 2015-06-04

The depth of China's opening-up policy, more goods are sold overseas, as outer packing paper barrel, followed across the goods, the cost of the implementation. But in the process of transportation, there are some paper barrels of damage, the leakage problem, it is one of the biggest paper barrel quality problems, from the height of the enterprise high.

The main factors influencing the paper barrel quality problem and solving method basically has the following several aspects:

1, the original, the quality of the auxiliary materials

Cardboard barrels used raw materials include: kraft paper, adhesive, strip steel, plywood, etc. What is now worried about is the cardboard barrels competition among manufacturing enterprises mainly on price competition, quality rarely participate in the competition. Most enterprise for customer had to cut corners, with a low quality of paper instead of high quality paper, reduce thickness and width of the strip, plywood material uneven, lack of material, such as fault, poor quality of adhesive, barrel body low adhesive strength between layer and layer, even out of, etc. So the physical performance index of the product turn out must be unqualified, easy to cause customer quality complaints.

2, process problems

(1) on (under) the tight junction welding bad directly affect the strength of the cardboard barrels:

In order to increase the drum strength, on the drum, the mouth area is equipped with upper and lower tight hoop, barrel on parts of the barrel hoop called to tighten the band, the lower barrel hoop called under tight hoop. Fluctuation is the main purpose of hoops to ensure the strength of the drum, and keep the barrel mouth, barrel in roundness; Reinforcing closure, can make the barrel and the barrel mouth positioning well, keep good for the interchange function; Fixed barrel body and the bottom as a firm as a whole. Tight production material is galvanized steel strip, steel strip cut into the length of the regulations, junction after welding and barrel mouth parts, namely into tight pressed into an organic whole, such as welding current, breakdown welding spot, easy to cause virtual welding current is too small, whether it is the what kind of situation, tight hoop will be useless, barrel body and the bottom or barrel mouth out, if appear at the bottom of the barrel with joint release, if the material is flammable, explosive and toxic substances, such as dangerous goods, will lead to serious accidents.

(2) the influence of paper barrel bottom forming method:

Paper barrel production in the process of strengthening body connected to the bottom of the main rely on bottom sealing process to complete, so the sealing process of operation quality and the accuracy and precision of bottom sealing equipment will affect the overall quality of the drum, the back cover mold in the process of work, die ring vertical plane prone to wear and constitute the tightness of paper at the bottom of the barrel is differ, which affects barrel body and the bonding strength of the bottom. In the drum transportation or in use process, the paper barrel itself load heavy, barrel body and bottom plywood from, eventually led to the built-in product leakage, is the main cause of almost all domestic paper barrel manufacturer in production and manufacturing process, adopt plywood as bottom, plywood due to material defect, easy to be affected with damp be affected with damp deformation, lead to mildew, fall off in the process of transport and use.
