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. Valve bags have the characteristics of improving packaging efficiency, convenient transportation, strong firmness, and low breakage rate. Therefore, they are widely used to package edible powder, chemical powder, fertilizer, synthetic materials, grain, salt, minerals and other powdered or granular solid materials and flexible items. In the process of filling the valve bags, automatic quantitative filling packaging machines are usually used to operate, which greatly improves the filling efficiency of the valve bags for materials. However, it still has the following disadvantages in actual use:

The valve bag powder quantitative automatic packaging machine can quantitatively fill the material inside the valve bag to improve the processing efficiency. However, during the actual filling, the produced and processed valve bags are usually folded for storage, and the staff is required to unfold the folded valve bags and tidy up the valve mouth so that the discharge nozzle can be smoothly inserted into the inside of the valve bag. However, the feed port of the valve bag that is not filled with material is prone to wrinkles, which makes it difficult to insert the discharge nozzle smoothly, reducing production efficiency;

[0004] The discharge nozzle of the valve bag automatic quantitative filling packaging machine is often fixed on the surface of the machine. After the valve bag is filled, the staff needs to manually remove the valve bag from one end of the discharge nozzle. However, the volume of the valve bag is usually large, and a large amount of material is often filled in it, which makes it difficult for the staff to carry the filled valve bag, and the operation is time-consuming and laborious.
