[0009] The two conveyor belts are located on the same straight line, and their inner ends are arranged adjacent to each other. There is a gap between the two conveyor belts (it is difficult to avoid, as the conveyor belts are wound around the drive shaft and have arc-shaped ends), and a sliding surface can be set between them for transition. Existing bottle return machines usually only push the glass bottles along the annealing kiln, which may cause a gap between the glass bottles input by the two conveyor belts. If the conveyor belt sends the glass bottles at the inner end to the sliding surface (transported perpendicular to the annealing kiln), the glass bottles at the inner end may slide in the direction of the annealing kiln, resulting in uneven arrangement of the glass bottles or even tipping over.
