[0002] After the existing fin tubes are produced and discharged, they still need to be manually tested for multiple parameters, such as whether the total length of the whole tube and the length of the interval light tube reach the calibration value. After the inspection and sorting, they need to be transported, classified and isolated. Subsequently, the fin tubes that meet the requirements are transported to the corresponding machines for subsequent processing, and then weighed and tested. Such repeated isolation, transportation and transfer work is time-consuming and labor-intensive, and the production efficiency is low.

At this time, the servo motor reverses, and the remaining tubes fall back to their original positions together with the transmission chain, and the blocking cylinder retracts. Under the action of gravity, the single finned tube rolls and slides to the top feeding mechanism along the slope of the discharging platform. Since the suspended pressing mechanism is parallel to the discharging platform and only adjusts the entry spacing of the single finned tube, it is effectively ensured that the finned tubes on the platform will not be stacked, thereby realizing the orderly discharging of the single finned tubes in the whole frame;

The multi-parameter detection of the produced finned tubes and the orderly upper discharge feeding can be organically integrated, which provides an assistance for improving the intelligence level of the multi-parameter detection equipment of the finned tubes.
