Background

When the existing filling device is used for filling bottles, materials in the filling device are output from a discharge port and then enter the bottles under the action of gravity, wherein when the materials at the edge of the discharge port fall, the falling path of the materials does not fall along the vertical direction under the action of the tension of the materials, but moves downwards while moving to one side far away from the axis of the filling device, namely, the materials falling from the discharge port gradually diffuse outwards from top to bottom. The distance of the bottle mouth and the discharge port of the bottle is larger, the distance of the transverse deviation of the materials is larger, when the materials fall to the bottle mouth, the materials falling from the edge of the discharge port deviate from the range of the bottle mouth when falling to the bottle mouth, and therefore partial materials cannot fall into the bottle, and the problem of food safety is caused. The height of the discharge port of the existing filling device cannot be adjusted, and the height of a conveying belt used for conveying bottles on the lower side of the filling device cannot be adjusted. This will result in: when the bottle that highly is lower moves to the downside of discharge gate along with the conveyer belt, the bottleneck of bottle is great apart from the distance of discharge gate, leads to some materials can't fall into the bottle, causes food and security problem. In order to fill such low-height bottles, a cushion block is generally arranged on the upper side of the conveying belt, the bottles are cushioned through the cushion block, but in order to limit the bottles on the cushion block, the height of a limiting block used for limiting the bottles on the conveying belt needs to be increased, so that the height of the limiting block is greater than that of the cushion block, and the limiting block interferes with nearby parts in the movement process.
