Danqi full paper bucket One of the main products our company operates and supplies is fibre drum Reasonable structural design is crucial for the quality of paper barrels during the process of structural design. User friends should also pay attention to the quality and craftsmanship of the product when choosing it. What aspects should be considered when designing a product? Let's take a look at these issues together:

1. Requirements for the selection of raw materials for Danqi's full paper bucket:fibre drum The structure of the paper drum is multi-layered, and the paper drum is manufactured by spiral winding method. The various indicators of the cardboard are related to the overall quality of the product. Generally, the selected cardboard has a weight of 300-360 grams/square meter. To ensure the strength and rigidity of the paper drum, the ring compression strength of the cardboard raw material is not less than 18N.m/g for those with a weight of 300 grams/square meter, the burst resistance index is not less than 3.0kpa · ㎡/g, the transverse folding resistance is not less than 50 times, and the moisture content is not more than 10%.

2. The design of the concave ring groove on the upper and lower parts of the paper barrel: It is fixed on the paper barrel to enhance its strength, and the lower mouth is rolled with a concave ring groove, also known as a barrel hoop. The pole clamp at the barrel mouth is called the upper barrel clamp, and the lower (bottom) barrel clamp is called the lower barrel clamp. The main function of the upper barrel hoop is to ensure the strength of the paper barrel and maintain the roundness of the barrel mouth. ② Strengthening the closure device can ensure good positioning and interchangeability between the lid and the mouth of the barrel. ③ Position the mold of the paper barrel forming equipment (sealing machine).

3. fibre drum Strength and deformation design: The strength of a paper drum is not only related to the raw materials used, but also to the thickness of the drum and the magnitude of the axial force acting on it. With a certain material and circumference, the vertical compressive strength of the drum should be greater than 8000N, the lateral compressive strength should be greater than 4000N, and the puncture strength should be greater than 10N.
