The invention discloses an automatic glue spraying and glue sheet pasting machine for shoemaking. The automatic glue spraying and glue sheet pasting machine comprises a workbench, a hot-melt glue sheet picking and transferring unit, a pasting unit, a hot-melt glue sheet containing box, a glue spraying head and a heating spraying head. The hot-melt glue sheet picking and transferring unit is vertically suspended above the workbench through a first frame, and the hot-melt glue sheet containing box, the glue spraying head, the heating spraying head and the pasting unit are all fixedly arranged onthe workbench. The hot-melt glue sheet picking and transferring unit comprises a first sliding frame, a second sliding frame, a first linear motion cylinder, a second linear motion cylinder, a connecting rod and a first negative-pressure rubber adsorption plate and further comprises a first driving mechanism for driving the first sliding frame to slide along a first horizontal sliding rail, and asecond driving mechanism for driving the second sliding frame to slide along a second horizontal sliding rail. The pasting unit comprises a guide rod, a sliding block, a stand column, an ejector rod,a second negative-pressure type rubber adsorption plate, a gear rack and a gear.
