A rotor structure for a motor includes a shaft, a single magnet, and two fixing seats. The shaft passes through the single magnet and the two fixing seats, with the two fixing seats being adjacent to and abutting against two end faces of the single magnet, respectively. The single magnet fits with a small clearance or loosely fits the shaft, and the two fixing seats tightly fit the shaft, such that the single magnet is positioned at a predetermined position relative to the shaft without rupture. Furthermore, each of the two end faces and two abutting faces are formed with rough surfaces and/or with corresponding grooves and protrusions, so as to achieve a stable-engaging effect between the single magnet and fixing seats.

The invention discloses a treatment machine for increasing surface roughness of plastic foam particles. The treatment machine is mainly characterized in that a driving shaft of an electric device is fixedly connected with a flying bar in a material bin inner cavity; at least two sets of sawtooth-shaped blades are distributed and connected on a frame of the flying bar in the axial direction; the edges of blade teeth of the opposite sawtooth-shaped blades of on the flying bar are annularly sleeved with a sleeve with sieve holes distributed in the outer circle with the distance a=2 mm to 6 mm, and the sleeve is connected with a material bin; a feeding hole is formed in the other end of the material bin and corresponds to a feeding end opening of the flying bar. Under the action of outside suction force in the work process, the blade teeth on the sawtooth-shaped blades on the flying bar rotate, the surfaces of the plastic foam particles adsorbed on the surface of an inner cavity of the sleeve are scratched and pulled, roughness is increased, and then the plastic foam particles are sucked into the material bin through the sieve holes in the surface of the inner cavity of the sleeve through extrusion to be discharged out. The plastic foam particles with the rough surfaces are in mixed and coated connection through cement and pulverized fuel ash, the adhesive force is high, mixtures are evenly stirred, the material of a forming die shell is even and dense, connecting strength is high, and machining quality of die shell production is improved.

Each of a first rotary blade and a second rotary blade includes a rough surface portion and a smooth surface portion.
