FIG. 11 is a top view of the structure of FIG. 10. As shown in Figs. 10-11, the difference between this embodiment and the above-mentioned embodiment shown in Figs. 8-9 is that a backing wheel 76 is also fixed at the bottom of the second grinding wheel 71. The diameter of the supporting wheel 76 is larger than the diameter of the second grinding wheel 71, so that the supporting wheel 76 abuts against the edge of the sole support plate 64 during grinding, and the second grinding wheel 71 contacts the edge of the sole. At this time, the grinding is performed according to the shape of the sole support plate 64.

Wherein, when the sole support plate 64 is made, it can be offset inward by a certain distance according to the outer contour of the sole to ensure that the second grinding wheel 71 can always be effectively ground to the sole during grinding.

The working principle of the second embodiment is:

First place the sole on the sole support plate 64, the pressing cylinder 66 drives the sole pressing plate 65 to compress the sole; then, the polishing cylinder 75 drives the second grinding wheel mounting plate 73 to move toward the sole until the supporting wheel 76 abuts the sole support plate 64 At the edge; at this time, the exterior wall polishing motor 72 and the servo motor 67 are activated at the same time. During the polishing process, due to the constant force, the supporting wheel 76 always contacts the sole support plate 64 with a constant force. The sole support plate 64 rotates once, and the second grinding wheel 71 can effectively grind the sole for one full circle. After the polishing is completed, the cylinder 75 is polished to keep the second grinding wheel 71 away from the sole.

In summary, the present invention provides an adaptive sole polishing mechanism. When the bottom of the second grinding wheel 71 is not provided with the supporting wheel 76, the second grinding wheel 71 is constantly pressed against the sole so that the walking track of the second grinding wheel 71 always follows the sole; and when the supporting wheel 76 is provided at the bottom of the second grinding wheel 71, The supporting wheel 76 is constantly pressed against the sole supporting plate 64 so that the walking track of the supporting wheel 76 always follows the sole supporting plate 64. The two polishing methods do not need to reprogram the trajectory program for the soles of different sizes, which greatly reduces the difficulty of use, improves the adaptability of the polishing mechanism, and at the same time solves the problem of inconsistent polishing depth caused by the difference in the shape and size of the sole. Improve the quality of polishing, so it has a high industrial value.

Please refer to Figures 12-13. Figure 12 is a schematic diagram of a radial cross-sectional structure of a second grinding wheel of a sole outer wall polishing device 100 according to a preferred embodiment of the present invention. Figure 13 is a preferred embodiment of the present invention. The top view of the second grinding wheel structure of the sole outer wall grinding device 100. As shown in FIGS. 12-13, the second grinding wheel includes a wheel-shaped base 711, which can be made of a metal material; the outer surface of the wheel-shaped base 711 is formed with a polishing layer 712 for grinding the edge of the sole.

The grinding layer 712 is in contact with the edge of the sole for grinding; the grinding layer 712 includes: a cylindrical cylindrical grinding layer 714 formed along the outer surface of the wheel-shaped base 711 and an arc formed along the outer surface of the wheel-shaped base 711 connected to the cylindrical grinding layer 714磨层713。 Polishing layer 713. Among them, the cylindrical grinding layer 714 is in contact with the thicker part of the sole for grinding, and the arc-shaped grinding layer 713 is in contact with the thinner part of the sole for grinding. The deformation of the sole caused by the grinding force is compensated by the arc section, ensuring that the entire upper and lower edges of the sole can be effectively ground.

The arc radius R of the arc-shaped grinding layer 713 can be set to 2mm-20mm, and the specific arc radius value can be adjusted according to the sole material, wall thickness, and the amount of deformation caused by grinding.

Wherein, the number of the arc-shaped polishing layer 713 can be one, which is formed on the top or bottom end of the cylindrical polishing layer; it can also be two, which are respectively formed on both ends of the cylindrical polishing layer. When two arc-shaped grinding layers 713 are used, the arc radii of the two arc-shaped grinding layers 713 can be set to be the same. If only one of the arc segments is required for grinding during grinding, the other arc segment can be used as a spare , When the abrasive grains on one side of the arc segment are blunt, turn it over and use the other side of the arc segment for grinding, which can increase the effective service life of the second grinding wheel. Of course, the arc radii of the two arc-shaped polishing layers 713 can also be set to be different, which can satisfy different types of shoe soles.

The arc-shaped polishing layer 713 and the cylindrical polishing layer 714 are both provided with alloy or diamond particles, which can be fixed on the wheel-shaped base 711 by brazing or electroforming. The alloy particles can have a particle size of 20 mesh to 400 mesh.

A through hole 715 is provided in the center of the wheel-shaped base body 711 to facilitate the fixing of the second grinding wheel through the second grinding wheel shaft and the driving element to drive it to rotate.

In summary, the second grinding wheel compensates for the deformation of the sole by the grinding force through the arc section, ensuring that the entire upper and lower edges of the sole can be effectively ground, so it has a high industrial value.
