Description

Technical Field

[0001] The utility model relates to the field of valve bags, and more specifically, to a valve bag. Background Art

[0002] Valve bags, commonly known as paste-bottom bags, are internationally popular packaging bags. They are fed from the top or bottom valve port and use special filling equipment to fill the materials into cubes. The bags are neatly stacked and beautiful, and are environmentally friendly bags. Valve bags are mainly used to package edible powder, chemical powder, fertilizer, synthetic materials, explosives, grain, salt, minerals and other powdered or granular solid materials and flexible items. They are particularly suitable for export companies and can improve the packaging grade of products.

[0003] After being filled with products, existing valve bags basically need to be stacked for storage, but the existing valve bags do not have a limiting function, so they will gradually tilt when stacked, making the valve bags prone to tipping over, thereby reducing the storage capacity of the same storage bin. In addition, some valve bag stacking structures on the market are prone to the risk of cracking the raw materials in the compression cavities of adjacent valve bags when stacked for a long time. Therefore, a valve bag support structure is needed that can facilitate valve bag stacking and will not compress the raw materials in the valve bags. Utility Model Content

[0008] By adopting the above technical solution, the telescopic blocks can be unfolded to support the valve bag and facilitate subsequent stacking. At the same time, the unfolded telescopic blocks form a certain inclination, which can facilitate the valve bag to have more space on the side away from the feeding end when the bag is filled with raw materials.
