A plurality of spaced support mechanisms for supporting shoe lasts are fixedly installed along the traveling direction of the chain plate on the middle of the outer end face of the chain plate. A working chamber is installed at the upper end of the conveyor. A through opening is arranged at each of the two ends of the working chamber, and the through openings are arranged along the traveling direction of the chain plate. The top wall, side wall of the working chamber and the chain plate enclose a long cylindrical channel for the shoe last carried by the support mechanism to pass through. A grinding device for automatically cleaning the adhesive film adhered to the shoe last is also installed on the working chamber. By installing the support mechanism and the grinding device for the shoe last on the plate chain conveyor, the automatic grinding of the shoe last can be realized, the grinding efficiency is improved, and the labor intensity of workers is reduced.

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art:

[0004] After the shoes are made, in order to facilitate the removal of the last, a structure for facilitating the extraction action is usually provided on the current shoe last. For example, for the shoe last described in the above patent, by providing an insertion hole at the shoe mouth position, it is convenient for the assembly of an external pull rod.
