[0002] In order to make sports shoes more colorful and richer in layers, the uppers are generally made of shoe pieces of various shapes and colors glued to the uppers using a hot stamping machine.

[0003] The existing semi-automatic hot stamping machine needs to be manually loaded at the loading station onto the mold for positioning the shoe upper; then it is transported to the hot stamping station for hot stamping. After the hot stamping is completed, it is output to the loading station to remove the hot stamped shoe upper and put the shoe upper waiting for hot stamping on the mold again.

[0004] In this semi-automatic hot stamping machine structure, before the mold is loaded, the upper that has been hot stamped needs to be taken out and then placed on the inclined surface waiting for hot stamping. During the process of loading or unloading the upper, there is no mold and upper processing under the hot stamping machine, and the hot stamping machine is in a non-working state during this period; therefore, the processing time interval between two adjacent uppers is long, and the processing efficiency of the hot stamping machine is low.
