Description

Technical Field

[0002] Ton bags, also known as bulk bags, ton bags or bulk bags, are flexible packaging containers that are mainly used to load and transport various types of bulk materials, such as chemicals, grains, minerals and building materials. These ton bags are designed according to international standards and have moisture-proof, dust-proof and radiation-resistant properties. They are widely used in various industrial fields. In order to remove and put materials from the ton bag into the production or processing process, it is usually necessary to use a feeding mechanism as an auxiliary device. This ensures that the materials can be taken out and put into the production line or processing equipment smoothly and efficiently.

[0003] At present, the common ton bag feeding equipment usually hangs the ton bag at the top, so that the discharge port at the bottom is exposed. Then, the material is quickly discharged from the ton bag by applying vibration through vibrators or manual knocking. However, this method is prone to cause "bridging" phenomenon, resulting in uneven material feeding, which in turn affects production efficiency and product quality. In addition, due to the vibration and impact generated when the material falls, a large amount of dust will be raised, resulting in a poor production environment and adversely affecting the health of the operators.
