The production process of paper drums is divided into three steps:

1. Cut the raw paper and add the configured adhesive to roll the barrel with a reel and dry it.

2. Then, the configured iron hoop extension and the barrel support are formed, and the barrel bottom is supported on the bottom, and the iron mouth is painted.

3. Finally, the prepared locking hoop and upper cover are combined with the barrel body, and the barrel body is printed with a trademark to complete the manufacturing process of the paper barrel.

The paper barrel quality requirements are as follows:

For export

Paper bucket specifications

Small caliber paper barrel diameter: 30, 35, 37, 38, 40, 42, 44 CM height is generally arbitrary (less than 75CM)

Large diameter paper barrel diameter: 50, 55, 60, 65, 70, 80, 90, 100 CM height is generally arbitrary

Full paper square bucket: 35, 45, 55, 100 CM (also became full paper IBC)

Domestic and international standards for paper drums

With the deepening of China's opening-up policy, more and more products are exported overseas, and paper barrels as outer packaging materials also realize their own value as the products float across the sea. However, during the transportation of Shengshi Wendu wooden doors, there is also the problem of leakage of paper barrels. This is the most serious quality problem of paper barrels, which must cause the height of the enterprise. The leakage of the paper bucket is mainly caused by the heavy load and large deformation of the paper bucket during use or handling, which causes the barrel body to detach from the bottom of the bucket. The main reason is that there are still some problems in the production process. One is the material problem. The plywood used has an impact on product quality. This is because when the bottom cover of the paper bucket is made of plywood, the thickness of the selected plywood is uneven, and most thicknesses do not meet the requirements. In addition, the plywood layer has low adhesive strength between layers, and it is easy to detach from the barrel body. The tolerances of plywood blanking dimensions are inaccurate. Therefore, the selection of raw materials should be consistent with the standard plywood materials. Tolerances and quality control. The thickness of the plywood should be determined according to the maximum weight of the contents of the paper drum. When the weight of the paper drum is about 50 kg, the thickness of the plywood should not be less than 6 mm. The second is the problem of paper barrel production equipment. In the production process of paper barrels, the connection between the barrel body and the bottom of the barrel mainly depends on the bottom sealing molding process. Therefore, the operation of the equipment for forming the bottom cover will affect the overall quality of the paper barrel. For the operation of the equipment, the size changes of the various parts of the bottom sealing mold should be checked frequently. Because when the mold closes the bottom of the paper sealing barrel, the vertical plane of the lock ring mold is liable to deviate, resulting in uneven binding of the bottom of the paper barrel, which affects the degree of fit between the bottom of the barrel and the barrel.
