Description

Technical Field

[0002] Ton packaging bags are a type of container unit equipment, mainly used for the transportation of bulk powder and granular materials, and are widely used in cement, fertilizers, chemical raw materials, ores, etc.

[0003] In industrial production, materials are filled into ton packaging bags through ton packaging machines, and the filled ton bags need to be transported directly from the ton packaging machine station to the storage warehouse. During the transportation process, the ton bags often encounter the problem of rotating the ton bags in a certain direction before transportation.

[0004] The patent "A three-link chain plate type transfer chain plate machine" (CN207985918U) proposes that when receiving ton bags, the long chain plate in the middle part first contacts the ton bag to provide tension. After conveying a certain distance, the long chain plate and the short chain plates on both sides provide tension at the same time to convey the ton bag to the middle of the transfer chain plate machine. Since the long chain plate only provides tension to one-third of its width when it just contacts the bottom of the ton bag, when the bottom of the ton bag is soft, there is still a bag jam in the gap between the front conveyor and the transfer chain plate machine.

[0005] Therefore, in order to meet the problem of ton bag steering and conveying during factory production and ensure the success rate of ton bag conveying, it is urgent to develop a ton bag packaging material steering and conveying device. Summary of the invention
