[0038] The working principle of the edge binding device for schoolbag production in the utility model is as follows:

[0039] When the bag production hemming device is in use, one end of the hemming strip is fed into the limiting structure. In the process of feeding into the limiting structure, it is guided by the guide strips on both sides. After passing through the limiting structure, it enters the indentation mechanism and the auxiliary forming block. Then, the driving motor in the indentation mechanism is started to drive the pressing roller to rotate. The pressing roller cooperates with the auxiliary forming block to drive the hemming strip to move. In addition, the hemming strip is indented to cause corresponding deformation of the hemming strip. The hemming strip is formed through the forming space formed between the auxiliary forming block and the pressing roller to achieve the hemming strip forming effect. As the pressing roller continues to rotate, the hemming strip will be continuously formed. Then, one end of the hemming strip will be led out by the limiting rod to prevent the hemming strip from warping after roller forming, thereby affecting the final forming effect.

[0040] As attached Figure 5 As shown, when the edge strip is indenting, the electric push rod and the driving motor in the indenting mechanism can be flexibly changed according to the indenting requirements, thereby meeting different indenting tasks of the edge strip, producing different indenting effects, and improving the use efficiency of the indenting mechanism;

[0041] As attached Figure 5 As shown, when facing hemming strips of different widths, the spacing of the guide strips can be adjusted to assist the hemming strips in better moving work;

[0042] Furthermore, the symmetrically distributed guide strips can be biased to achieve the effect of eccentric indentation, satisfying the eccentric processing of the hemming strips;

[0043] As attached Figure 4 As shown, the limiting structure and the limiting rod can be adjusted accordingly according to the specifications and processing requirements of the edging strip. By controlling the distance between the first limiting roller and the second limiting roller and the upper surface of the fixed seat, different downward pressures can be achieved. When the outer surface of the edging strip is relatively smooth, additional friction can be provided, and the edging strip can be indented in cooperation with the indentation mechanism.
