Rail transition device and roasting machine

The utility model discloses a rail transition device and a roasting machine, and belongs to the technical field of pellet roasting. The rail transition device comprises a movable frame, a balancing weight, a straight rail, a side rail, a sliding rail and a bent rail. The straight rail is connected with the side rail, and the side portion of the side rail and the end, facing the sliding rail, of the straight rail form a first groove. The sliding rail is connected with the bent rail, and the sliding rail is arranged in the first groove in a sliding mode; the sliding rail is connected with the movable frame, and the bent rail is fixedly connected with the movable frame. And the movable frame is connected with the balancing weight. According to the track transition device and the roasting machine, displacement caused by thermal expansion and cold contraction in the operation process of the roasting machine trolley can be compensated, and the phenomenon of trolley falling is avoided. 本实用新型公开了一种轨道过渡装置及焙烧机，属于球团焙烧技术领
