Embodiments of the present application provide a feeding device for loading a material into a container, which relates to the technical field of product assembly. The feeding device is configured to load a material into a container having an opening. The feeding device includes a pressing unit. The pressing unit includes a pressing member having a pressing plane, and a driving member configured to drive the pressing member to move cyclically along a closed track. The closed track includes a first planar track segment, and when the pressing member moves along the first planar track segment, the pressing plane forms surface contact with the material and keeps extending in a material loading direction, the material loading direction being a movement direction of the material relative to the container. The feeding device can reduce damage to the material during a feeding process.

Feeding device
