9. The refrigerator glass door metal end stop forming line according to claim 8, characterized in that: in an outlet guide mechanism of the rolling mill (4), the tops of mounting plates (4.11) on two sides are also provided with suspension beams (4.17) in an erected mode, the suspension beams are rotatably provided with wheel shafts (4.14) which are axially horizontal along the left and right sides through vertical connecting rods, one ends of the wheel shafts (4.14) are coaxially and fixedly provided with length measuring rollers (4.15), the length measuring rollers (4.15) are in contact with the upper surface of a plate (7), the other ends of the wheel shafts (4.14) are also coaxially provided with length measuring encoders (4.16), the plate (7) drives the length measuring rollers (4.15) and the wheel shafts (4.14) to synchronously rotate when being conveyed to the cutting machine (5), the rotating distance is measured by the length measuring encoders (4.16) so as to measure the length of the plate (7), the length measuring encoders (4.16) are connected with an external controller, the external controller is also in control connection with a driving servo motor (5.3) in the cutting machine (5), and therefore the external controller can obtain the transmission length of the plate through the, the servo motor (5.3) is controlled and driven to work to realize the chasing and shearing cutting of the plate.
10. The refrigerator glass door metal end rail forming line according to claim 1, characterized in that: material blocking supports (8) are respectively vertically arranged between the uncoiler (1) and the leveler (2), between the leveler (2) and the punching machine (3) and between the punching machine (3) and the rolling mill (4), and a plate (7) output by the former equipment downwards passes through the material blocking supports (8) and then upwards enters the latter equipment.
