[0040] The working process of this adjustable spacing steel mesh folding device is:

[0041] When folding the steel mesh, the steel mesh is placed on the loading platform 5 and pushed in the direction of the folding assembly, so that the non-bent steel bars at the end of the steel mesh, which are transverse steel bars in this specific embodiment, enter the feeding trough 14, and the steel bars that need to be bent at the end of the steel mesh, which are bent steel bars in this specific embodiment, extend above the bending shaft 22; turn on the tensioning cylinder 4, and the hook 7 moves along the upper front along the feeding direction until the non-bent steel bars are tightly attached to the positioning groove 15; then turn on the drive motor 3, and the drive shaft 21 drives all the bending parts 10 to rotate to realize Now bend, the bending part 10 rotates 180°; the driving motor 3 is reversed until the bending shaft 22 returns to zero position, and the tensioning cylinder 4 is extended at the same time, and the hook 7 moves backward and downward; pull out the steel mesh; when it is necessary to adjust the spacing of the folding unit 2, loosen the locking bolt 29 and the locking bolt 2, and according to the mesh width, push or pull the two positioning plates 8 of the mobile folding unit 2, and drive the hook to move.
