Abstract
The invention relates to a feeder widely used in plastics and rubber industries, which is especially suitable for bulk density and high powder mixture operation. The feeder comprises a barrel, a hopper and a feed opening which are connected with the barrel, screws arranged in the barrel, a reducer and a motor. The feeder is characterized in that the screws are arranged in parallel and synchronously rotate; spiral grooves of adjacent screws are opposite and meshed with each other; and the number of the screws exceeds 12. The feeder has the following beneficial effects: a frequency conversion device is used for controlling the feed rate, thus realizing uniform, continuous and controllable feeding, and the screws which are horizontally parallel and meshed with each other are arranged, thus greatly enlarging the feeding area, preventing the materials from being bridged and layered and improving the feeding efficiency.
