10. A method of using a continuous feed geogrid welding system according to claim 5, comprising the steps of:

a. according to the requirement of the production beat, the transverse belt conveying and cutting mechanism simultaneously finishes transverse conveying and fixed-length cutting of two or more transverse belts at one time;

b. after a transverse belt cutting mechanism is opened up and down in a belt penetrating die in the mechanism, a plurality of cut transverse belts are conveyed to a set position along the product conveying direction under the state that the spacing is kept unchanged and the transverse belts are tensioned, the transverse belt automatic copying and transferring mechanism clamps a plurality of transverse belts rotated out by the transverse belt cutting mechanism through the clamping action of a telescopic cylinder, the transverse belt automatic copying and transferring mechanism moves a transverse belt group along the longitudinal direction towards the welding mechanism, the transverse belt cutting mechanism simultaneously rotates back to the initial position of the transverse belt cutting mechanism, and the transverse belt conveying and cutting work of the next round is started;

c. the transverse belt automatic copying and transferring mechanism moves to a set zero position, starts to keep the same stepping action as the belt conveying and shaping clamp, and synchronously moves in the same direction, so that the positions to be clamped at the two ends of the clamped transverse belt strip gradually enter the jaw of the clamping assembly; meanwhile, the moving frequency of the belt conveying and shaping clamp is consistent with the subsequent welding frequency, and the belt conveying and shaping clamp moves by one station every time the welding process is completed;

d. one or more transverse strips completely enter the clamping position of the belt conveying shaping clamp, and the clamping cylinder pushes the clamping jaw of the belt conveying shaping clamp to complete the clamping action on the end part of the transverse strip and reset rapidly; the belt conveying shaping clamp and the transverse belt automatic copying and transferring mechanism complete clamping of the transverse belt once and complete clamping of all the belts of the belt group step by step once each time the belt conveying shaping clamp and the transverse belt automatic copying and transferring mechanism move once;

e. after the belt feeding shaping clamp finishes clamping all transverse belts in the whole transverse belt automatic copying and transferring mechanism, the transverse belt automatic copying and transferring mechanism loosens the clamping of the transverse belts and longitudinally moves to an initial waiting position, and meanwhile, the other set of transverse belt automatic copying and transferring mechanism realizes end-to-end connection to ensure the stepping continuity of the welding belt feeding process;

f. tensioning a transverse strip in the belt conveying and shaping clamp in a stretching station, putting the transverse strip into a welding gun assembly for hot melt welding after tensioning, moving the welded transverse strip out of a welding position after welding, and cooling and shaping the transverse strip through an air cooling mechanism;

g. the transverse strips in the belt conveying and shaping clamp move to a discharging position, and the clamping of the transverse strips is released under the action of discharging release driving;

h. and the welded product which is recovered to the free state moves step by step under the stepping traction of the stepping rolling traction device and enters a subsequent automatic coiling device.
