The invention relates to the technical field of folium artemisiae argyi, and discloses a pressing device for extracting juice from the folium artemisiae argyi. The pressing device comprises a shell, the exterior of the shell is fixedly connected with a feeding port, the interior of the shell is fixedly connected with a photosensitive
assembly, the interior of the shell is provided with an electric telescopic rod, and the interior of the shell is fixedly connected with a
fixed frame; and a movable frame is slidably connected into the
fixed frame, and a rotating shaft is rotatably connected into the
fixed frame. Through mutual cooperation of the feeding port, the photosensitive
assembly, the electric telescopic rod, the fixed frame, the movable frame, the rotating shaft, a first
rotating disc, a connecting frame, a pressing plate, a telescopic rod and a movable filter screen, the device can automatically detect the amount of the folium artemisiae argyi, when the amount reaches a certain amount, an inlet is controlled to be closed, and the situation that in the juice extraction process, the juice quality is influenced due to the fact that dust enters inside is avoided, so that the effects of improving the juice quality and automatically
mashing the folium artemisiae argyi are achieved.
