The invention relates to a sole glue applying device used in shoe factories, in particular to a highly-efficient sole glue applying device used in shoe factories. The highly-efficient sole glue applying device used in shoe factories has the advantages of uniform glue applying, high glue applying speed and glue saving. The highly-efficient sole glue applying device comprises a support frame, a compression cylinder, a transfer box, a support, a slide rail, a slider, a disc, a first connecting rod, a strut, a wedge-shaped block, a connecting
pipe, an electronic control valve, a stirring tank, bearing bases, a rotating shaft, a gear, stirring rods, a rack, a guide rod, a liquid outlet
pipe, a first
check valve, a
piston, a push rod, a fixing plate, a spring, a contact wheel, a hose, a glue gun, a pedal and a motor. The motor rotates to drive the stirring rods to rotate, so that glue is stirred; by using the push rod and the
piston, glue enters the glue gun; the highly-efficient sole glue applying device achieves the effects of uniform glue applying, high glue applying speed and glue saving.
