Automatic inner tube splicing system

The invention discloses an automatic inner tube splicing system which comprises an incoming material conveying line, a material taking mechanism, a feeding turnover mechanism, a splicing machine and a discharging mechanism; the incoming material conveying line is used for conveying a non-spliced inner tube to a first position; the material taking mechanism is used for clamping the non-spliced inner tube from the first position to a second position; the feeding turnover mechanism is used for carrying the non-spliced inner tube from the second position to a third position, for turning over the two ends of the non-spliced inner tube to allow the two ends of the non-spliced inner tube to be opposite and for moving the two ends of the non-spliced inner tube to allow the two ends of the non-spliced inner tube to be in contact in zero distance; the splicing machine is used for splicing the two ends, being in contact in zero distance, of the non-spliced inner tube; and the discharging mechanism is used for transferri
