Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a screw feeding device directly driven by a frameless combined permanent magnet synchronous linear motor. Background technique [0002] Screw feeding is a kind of continuous conveying equipment without disturbing traction components. It uses the rotating screw to push the conveyed material along the surface of the fixed casing for conveying work. Its situation is like being held by a nut that cannot rotate. Like the translational movement along the screw rod, the force that keeps the material from rotating with the screw is the gravity of the material and the frictional resistance of the casing on the material. Screw feeders have been widely used in various industrial sectors, such as building materials, electric power, chemical industry, metallurgy, coal mining, machinery, grain and food industries, etc. [0003] Chinese patent CN206842362U discloses a premixed po...
