Description

Technical Field

[0001] The utility model relates to the field of logistics equipment, and particularly to a bag swinging buffer device. Background Art

[0002] As an important loading, unloading, storage and transportation equipment in the process of logistics operation, pallets play a huge role in modern logistics when used in conjunction with forklifts. In the process of automatic unloading and bagging of bagged items on the existing pallet assembly line, a certain number of pallets with items are placed in the unloading area through the assembly line; since the assembly line transmission has a certain speed, the pallets with items may collide with the rack due to inertia, which increases the risk for some fragile items. Therefore, in order to solve the deficiencies in the existing technology, a simple bag-swinging buffer device needs to be designed. Utility Model Content

[0008] As a further improvement, the upper buffer components are provided in sixteen groups at intervals about the buffer platform.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The materials and pallets are sent to the buffer platform through the conveyor belt. The materials are decelerated and buffered by the buffer rod matched with the torsion spring at the upper end to prevent collision with the frame. At the same time, the materials will drive the slider to slide in the slide rail assembly, and the slider drives the slide rod to move to the right and squeeze the spring. The guide surface on the right side of the slide rod will push the insertion rod to move upward until the insertion rod enters the slot, thereby locking the buffer platform and decelerating the materials. When the materials are taken away, the cylinder drives the upper fixed plate to rise, and the fixed plate drives the connecting seat at the upper end of the insertion rod to move upward synchronously, and then the insertion rod exits the slot, and the buffer platform is reset under the action of the spring to continue buffering the next material.
