Description

Technical Field

[0001] The utility model relates to the technical field of automatic bag turning, in particular to an automatic bag turning mechanism for a container bag with good stability. Background Art

[0002] FIBCs are flexible transport containers widely used for transporting powdered, granular, and bulky items such as food, grains, pharmaceuticals, chemicals, and minerals. Developed countries widely use FIBCs for transportation and warehousing. Also known as flexible bulk bags, tote bags, and space bags, these bags, also known as FIBCs, are a type of containerized unit (FIBC) that, when used with a crane or forklift, enables unitized transportation. They are suitable for transporting large quantities of bulk powders and granular materials.

[0003] The Chinese authorized publication number is CN 209794719 U. This automatic bag-turning mechanism, when in use, secures the bag's opening with a clamp. The lifting cylinder is then activated to move the cone-shaped rubber pressure block upward, gradually flipping the bottom of the bag over the clamp. The blower is then activated to completely turn the bag over, improving turnover efficiency while reducing worker labor. The mechanism is stable and reliable, highly adaptable, and practical.

[0004] However, this patent still has certain shortcomings when in use. The existing automatic bag-turning mechanism generally uses a fan to turn the bags when in use, but the container bags are large in size. When using a fan to turn the bags, it will generate a lot of noise, causing noise pollution to the surrounding environment and affecting the comfort and health of the staff. Moreover, the fan needs to work continuously when turning the bags, and the use process is very energy-consuming. Therefore, it is necessary to change the bag-turning method and use a mechanical method to turn the bags. In addition, the bag-turning mechanism is generally a fixed structure, and the specifications and sizes of the container bags are various. Therefore, the bag-turning quality when the bag-turning mechanism is used to turn the container bags is poor, and the bag openings may even stick together easily after turning the bags.
