Abstract

The invention relates to a glue-pouring machine which comprises a glue-pouring fixing rod and a glue-pouring product fixing mechanism. A glue-pouring product is provided with a glue-pouring hole; the glue-pouring machine also comprises a rotating platform; the fixing mechanism is installed on the rotating platform and is used for fixing the glue-pouring product, so that the glue-pouring hole is aligned with a rotating shaft of the rotating platform; and the rotating platform is used for driving the glue-pouring product to carry out fixed-point rotation around the glue-pouring hole. Thus, when glue is poured, colloids poured through the glue-pouring hole diffuse towards the periphery under the action of rotating centrifugal force and are gradually accumulated and encapsulated from the edge to the center (such as an axis of rotation); and by utilizing the centrifugal force, air gaps among the colloids can be effectively avoided, so that the glue is uniformly poured. The glue-pouring machine can be widely applied to glue-pouring various products glue-poured through the hole.
