Further, the winding speeds of two adjacent winding rollers are kept consistent. The winding speed of the grid to be wound can be consistent, so that the moving speed of the grid is consistent, and the condition that the grid to be wound is mistakenly wound and loosened is avoided.
And further, in the second step, the cutting mechanism cuts the grid to be wound to form a margin of a space between two adjacent sections of grids. The allowance enables a space to be formed between two adjacent sections of grids, and the condition of mutual interference in the winding process is avoided.
Furthermore, in the second step, the collection roller is used for winding the allowance, and the collection roller and the winding roller are arranged in a staggered mode. The collection roller and the winding roller are arranged in a staggered mode, interference between the surplus and the grid to be wound can be avoided, the winding roller is used for winding the surplus, and the surplus is prevented from influencing the normal winding of the grid.
And furthermore, the rotating speeds of the winding roller and the collecting roller in the second step are consistent. The speed of the coiled grid and the surplus speed can be consistent, so that the moving speed of the grid is consistent, the size of the grid which is prevented from being cut is prevented from being influenced, and the edge of the coiled grid is guaranteed to be smooth.
Further, the width of the margin is 1-3 cm. The waste of the grids can be avoided, and the effect of keeping the distance between adjacent grids to be wound can be effectively achieved.
Furthermore, a correcting device for adjusting the grid winding error problem is arranged in the second step. When the grid deviates, the grid in winding can be corrected in time conveniently, and the condition that the grid is not wound normally and is interfered with an adjacent grid is avoided.
Further, in the second step, the cutting mechanism and the winding roller are started simultaneously. So set up, the coiling and the cutting synchronization of grid start, have guaranteed the synchronism of coiling with the cutting.
