Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging machinery, in particular to a mobile ton bag single-side bag hanging device. Background Art

[0002] The ton bag packaging machine is a large-scale weighing and packaging equipment used for ton bag packaging of materials. It is a multi-purpose packaging machine that integrates electronic weighing, automatic bagging and dust removal. It has a high degree of automation, high packaging accuracy, adjustable packaging speed, superior structure, and a unique pneumatic lifting system that makes it particularly easy to handle ton bag packaging and is very convenient for the subsequent processing. It is widely used in material packaging in the mining, chemical, building materials, grain, feed and other industries.

[0003] During the manual bagging process of the ton bag packaging machine, due to the large distance between the hanging ears, workers need to walk on four operating surfaces to hang the ton bag on the hanging ears. If the ton bag is too high, the manual operating platform needs to be built on three sides to meet production needs. Since the feed port is located in the middle of the hanging ear, the worker needs to lean forward when putting on the feed port, which is somewhat dangerous. The Chinese invention application with application publication number CN 112093145 A discloses a ton bag hanging device, which can effectively drive the movement of the movable hanging ear 1 and the movable hanging ear 2 through the movement of the iterative cylinder and the iterative cylinder guide rod, and then through the moving discharge port, the discharge port is swung to the middle position between the fixed hanging ear 1 and the fixed hanging ear 2, and the movable hanging ear 1 and the movable hanging ear 2 swing close to the corresponding fixed hanging ear 1 and the fixed hanging ear 2, which can effectively narrow the working range, and the iterative support shaft can effectively realize the iterative support of the discharge port, so as to achieve a better discharge effect, and the fixed plate A and the fixed plate B can effectively realize the overall fixation and installation, improve work efficiency, and greatly reduce the range of operation required when loading bags. Workers can load bags at a fixed point without walking, and the bag loading efficiency is improved. The bag loading port does not require the body to lean forward, and the discharge port is tilted downward as a whole, eliminating the risk of falling from a height caused by leaning forward. This working method of controlling the movement of the hanging ear by a cylinder to reduce the operating range required for bagging has a complex structure. The single-sided hook mechanism has a large range of motion of the rotating arm, which limits the applicable bag types. The cylinder pushes with a large impact force, which poses a certain risk of collision. Utility Model Content
