Detection channel angle adjustable X-ray machine and control method

The invention discloses a detection channel angle adjustable X-ray machine and a control method, and relates to the technical field of X-ray machines. The device comprises an inclined slide way, a rotating shaft is arranged at the feeding end of the slide way, and the slide way can rotate around the rotating shaft; an X-ray recognition mechanism used for recognizing good and bad materials is arranged on the sliding way, and a sorting and rejecting device used for sorting the good and bad materials is arranged at the discharging end of the sliding way. The X-ray recognition mechanism and the sorting and rejecting device rotate along with the sliding way and are kept static relative to the sliding way. By obliquely arranging the slide way, materials automatically slide down along the slide way under the action of gravity, the rotating shaft is arranged at the feeding end of the slide way, and the slide way can rotate around the rotating shaft to adapt to conveying of different types of materials; the X-ray reco
