Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment for fiber rod material packaging, and in particular relates to an empty box conveying mechanism of a fiber rod material box packing machine. Background Art

[0002] Rod-shaped fiber is made into a slender rod to facilitate subsequent processing and use. For example, cigarette filters are made from rod-shaped fibers. After forming, the rod-shaped fiber needs to be packed in boxes to facilitate subsequent transportation, storage and other processes. At present, in order to improve the boxing efficiency of fiber rods, technicians have developed a fiber rod boxing machine. The fiber rod boxing machine generally includes a silo, a rod conveying mechanism, an empty box conveying mechanism, a sorting mechanism, a pushing mechanism and a full box output mechanism. The rod conveying mechanism is used to convey the fiber rods to the silo, the sorting mechanism is used to sort and stack the fiber rods in the silo, the empty box conveying mechanism is used to convey the empty rod box, the pushing mechanism is used to push the sorted fiber rods into the rod box, and the full box output mechanism is used to send out the rod box filled with fiber rods, thereby completing the automatic boxing of the fiber rods.

[0003] The existing empty box conveying mechanism is mainly conveyed by a conveyor belt or a conveyor chain. For example, the Chinese invention patent with patent number ZL2011101814624 discloses an empty tray conveying device for a filter rod cartoning machine, which is provided with a push plate tooth on the conveyor chain. During the movement of the chain, the empty box waiting tray is longitudinally pushed by the push plate tooth, and then the empty box waiting tray is horizontally pushed by the cylinder to push the empty box to the cartoning station. In this structure, after the conveyor chain conveys one station longitudinally each time, it needs to stop and wait for the cylinder that pushes horizontally to complete the push and reset before it can move again. Therefore, the conveyor chain needs to be started and stopped frequently. However, the empty box waiting tray is just naturally placed on the conveyor chain, and the conveyor chain supports the empty box waiting tray from the lower end. Each start and stop of the conveyor chain is easy to cause the empty box waiting tray to tilt or even fall down under the action of inertia. In addition, the empty box actually takes an L-shaped route, and the empty box conveying cost is high and the conveying efficiency is low. Summary of the invention
