However, the EVA sole needs to be polished in the production of EVA foamed flip-flops, and the skin layer formed during the molding of the EVA mold is to better adhere to the non-slip bottom sheet, and the non-slip rubber bottom sheet also needs to be polished.

The existing sole polishing equipment cannot fix the flip-flops with soft material and irregular shape, so that the flip-flops move during polishing, the polishing area is not accurate, some parts of the sole are polished too much, some parts are not polished enough, the surface is uneven, which seriously affects the product quality and appearance. And the flip-flops are integrally formed, and the presence of the vamp can easily cause the flip-flops to have no stable support effect during polishing, reducing the stability of polishing.

[0003] 2. The existing sole polishing equipment cannot clean the debris generated during polishing in time, and the debris will accumulate on the workbench, which can easily cause secondary scratches on the subsequent polishing flip-flops, affect the smoothness and quality of the sole surface, reduce the product qualification rate, and debris entering the equipment can easily cause equipment failure, resulting in production interruption.

[0023] Please refer to Figure 3 and Figure 5As shown, the adjusting mechanism 64 comprises a first connecting block 641, the upper surface of the first connecting block 641 is slidingly connected with a sliding block 642, the inner cavity of the first connecting block 641 is rotatably connected with a second threaded rod 643, the outer surface of the sliding block 642 is fixedly installed with a driving rod 644, the upper side of the first connecting block 641 is provided with a lifting plate 645, the outer surface of the lifting plate 645 is provided with a driving groove 646, the four corners of the first connecting block 641 are fixedly installed with a receiving rod 647, the inner cavity of the receiving rod 647 is slidingly connected with a lifting rod 648, the inner cavity of the lifting plate 645 is slidingly connected with a stretching plate 649, the stretching plate 649 is used for supporting the part of the sole between the vamp and the sole, so that the whole sole can be supported, and when the stretching plate 649 is received, the slippers can be conveniently placed, the vamp and the supporting surface are prevented from contacting, the sliding block 642 and the second threaded rod 643 are connected through threads, the driving groove 646 is obliquely arranged, the driving rod 644 and the driving groove 646 are slidingly connected, the top end of the lifting rod 648 is fixedly connected with the outer surface of the lifting plate 645, and the first connecting block 641 is fixedly connected with the outer surface of the supporting plate 61. Since the slippers are mainly integrally formed, when the sole of the slipper is polished, the vamp and the supporting surface will be unstable when they contact when the slippers are placed on the tabletop with the supporting surface, and the sole is easy to be concave downward when polishing on the hollow supporting surface, thereby affecting the polishing effect. The adjusting mechanism 64 supports the polishing of the slippers, the back of the sole of the slipper is placed on the upper surface of the supporting plate 61, the second threaded rod 643 is rotated to drive the sliding block 642 to slide on the first connecting block 641, the sliding of the sliding block 642 drives the driving rod 644 to slide in the inner cavity of the driving groove 646, at this time the lifting rod 648 slides in the inner cavity of the receiving rod 647, so that the height of the lifting plate 645 changes, the back of the sole of the slipper is placed on the upper surface of the lifting plate 645, and the stretching plate 649 is pulled to stretch between the sole of the slipper and the vamp.

At this time, the limiting block 6585 is accommodated in the inner cavity of the clamping block 6581, that is, the second sliding rod 65810 slides in the inner cavity of the limiting block 6585 and extrudes the second spring 65811, and the first sliding rod 6586 and the grommet 6588 slide in the inner cavity of the sliding groove 6582, so that the clamping block 6581 and the limiting block 6585 can clamp the shoe sole. The clamping block 6581 is a commonly used rigid clamping limiting block 6585, and the limiting block 6585 is a flexible clamping. When the shoe sole slips or deviates during polishing, the clamping block 6581 is always fixed at a position and only relatively displaced with the shoe sole, and the limiting block 6585 is flexibly limited with the shoe sole.
