After the developing roller enters the discharging device 3 from the discharging position of the stepping type conveying device 2, the piston rod 331 of the second cylinder 33 extends out of the second cylinder 33, the developing roller moves downwards along the slide way 31 and is blocked by the two piston rods 331, the developing roller is blocked by the piston rod 331 and slowly stops on the slide way 31, the length direction of the developing roller is perpendicular to the second conveying direction b, the developing roller is aligned to a station of the glue cutting equipment, the piston rod 331 retracts into the second cylinder 33 according to a preset time interval, and the developing roller accurately falls into the station of the glue cutting equipment.

Because the developing rollers move a pitch distance to the first conveying direction a in an action flow that the movable toothed plate 232 of the stepping conveying device 2 moves up and down, and the subsequent developing rollers are independently guided into the stepping conveying device 2, each developing roller is completely limited by the tooth spaces of the fixed toothed plates 223 and is continuously arranged according to the tooth spaces of the fixed toothed plates 223, the feeding sequence and stability can be effectively ensured, when the developing rollers fall into the discharging device 3, the posture of the developing rollers can be adjusted to be transverse by the discharging device 3 (namely, the length direction of the developing rollers is vertical to the second conveying direction), and each subsequent developing roller can be accurately fallen into the rubber cutting device.

The above embodiments are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto. There are many variations in the shapes, constructions, and principles of the invention, such as, for example, the like. Therefore, any changes and modifications made without departing from the spirit and scope of the present invention should be covered by the present invention.
