Description

Technical Field

[0001] The utility model relates to the relevant fields of mechanical engineering, and in particular to a safety limiting device for a movable arm of a bagging lane. Background Art

[0002] With the rapid advancement of science and technology, mechanical engineers are constantly pushing the boundaries of technology to design more efficient, intelligent, and safer equipment. From sophisticated industrial robots to massive production line equipment, every mechanical engineering achievement embodies the wisdom and dedication of engineers. They are dedicated to optimizing mechanical structures, improving material properties, and developing advanced control algorithms to ensure stable operation in complex and changing working environments, achieving efficient production and processing. However, existing movable arms in bagging lanes still present some problems.

[0003] The original equipment was all started and stopped manually on site. This manual on-site start-up and shutdown method not only consumed a lot of human resources, but also led to low production efficiency. More importantly, the lack of a rising limit protection device made the rising height of the equipment during shutdown completely dependent on the operator's visual judgment. This not only led to inconsistent shutdown height standards and increased the complexity of operation, but also easily caused collision accidents between equipment due to misjudgment, posing a serious threat to the safety of the equipment itself and the surrounding environment.

[0004] Therefore, we make improvements to this problem and propose a safety limiting device for the movable arm of the bagging lane. Utility Model Content
