Then the piston rods of the first material feeding cylinder 16 and the second material feeding cylinder 17 are extended to perform two-stage material feeding action, drive the positioning material clamp 6 to advance on the first sliding rail 14 towards the cord cutting machine 2, so that the material head protrudes out of the cutting knife pressure plate of the cord cutting machine 2; Step three, as shown in the figure Figure 12 The first speed reduction motor 30 drives the traction frame 18 to move along the second sliding rail 23 on the top beam 21 towards the cord cutting machine 2, so that the traction material clamp 19 is in butt joint with the material head of the steel cord 46, and the material head enters between the movable clamping plate 28 and the fixed clamping plate 29; Step four, as shown in the figure Figure 13 The piston rod of the second material clamp cylinder 26 is extended, drives the rotating member 27 to rotate forward and thereby drives the movable clamping plate 28 to press down, clamps the material head of the steel cord 46 in cooperation with the fixed clamping plate 29, the piston rod of the first material clamp cylinder 9 is retracted, raises the lifting plate 10, so that the two sets of clamping plates 13 loosen the steel cord 46, and the piston rod of the first material feeding cylinder 16 is retracted, drives the positioning material clamp 6 to retreat for resetting; Step five, while the positioning material clamp 6 is resetting, the first speed reduction motor 30 drives the traction frame 18 to move along the second sliding rail 23 on the top beam 21 towards the transfer mechanism 4, so that the traction material clamp 19 pulls the steel cord 46 to move along the second roller conveyor 33 to carry out cord length setting. After the first speed reduction motor 30 moves to the length setting position and stops moving, and at this time the positioning material clamp 6 has been reset, then the first material clamp cylinder 9 lowers the lifting plate 10, so that the two sets of clamping plates 13 clamp the steel cord 46, the cutting knife of the cord cutting machine 2 is pressed down, clamps the steel cord 46 in cooperation with the cutting knife pressure plate, and the material feeding cylinder group 7 starts to repeat the working process of steps one to five; Step six, the first speed reducer motor 30 drives the traction frame 18 to move along the second slide rail 23 on the top beam 21 to the direction of the reversing transfer device 34, at this time, the lifting roller conveyor 41 is in the raised state, so that the cut steel cord fabric 46 is smoothly transferred from the second roller conveyor 33 to the lifting roller conveyor 41, the traction clamp 19 loosens the material head, the lifting cylinder 42 retracts the piston rod, the lowering roller frame 43 and the roller 44, the cut steel cord fabric 46 falls on the conveying belt 39, the second speed reducer motor 40 starts to drive the rotating shaft 35 to rotate, the rotating shaft 35 drives the driving wheel 37 to rotate, thereby driving the conveying belt 39 to move, the cut steel cord fabric 46 is 90° reversed and transferred to the next process, the traction clamp 19 starts to repeat the working process of steps three to six, and continuously operates. The application can not only eliminate the length deviation caused by belt slip, but also stabilize the clamping of the steel cord fabric 46 to separate and feed the material to a certain length, effectively improving the efficiency and effect of the steel cord fabric 46 length cutting, and reducing the labor intensity of the workers.

[0044] In the application, the description of the orientation or relative position relationship of the structure, such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like, is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the application and simplifying the description, and does not indicate or imply that the indicated structure must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the application.
