Above-mentioned design is compared in only making the regulating wheel support and lean on one side, plays the effect that higher efficiency made rubbish separate from the steel needle, prevents to appear fixing the problem that separation failure appears in the tension.

Furthermore, the electromagnet is a plurality of cuboid-shaped electromagnetic blocks, and the electromagnetic blocks are arranged along the conveying direction of the conveying belt. Compared with a larger electromagnet which is pressed down integrally, the design has higher adsorption effect on magnetic metal substances.

Furthermore, the top of the steel needle is conical. The above design has the effect of facilitating the detachment of the flexible substance from the steel needle.

Furthermore, a compression spring is arranged between the bottom of the steel needle and the first conveying belt. The design plays a role in protecting the steel needle by the buffer effect when the steel needle is under a larger pressure.
