The invention discloses a circulating
drying oven for leather products. The circulating
drying oven for the leather products structurally comprises a
jet engine, an exhaust column
pipe, an
alloy shell, a leather product
drying oven groove, encoding controllers, an integrated
electric control box, a rubber sealing plate, a drying oven door plate, an oven door hand dragging rod and L-shaped plug pincolumns. A
propeller of the
jet engine is inserted into the axis of the leather product drying oven groove in an embedded mode, and the leather product drying oven groove is embedded into the
alloy shell in a sleeved mode. The
jet engine comprises a jet
piston cylinder set, fan rotating mechanisms, mechanical switch supporting bases, separating plate transverse movement devices, conveying belt
pulley sets, lug plate supporting devices, shaft rod transmission mechanisms and a
turbine spiral device. The purpose that the effect of jet type gear-shifting heating of a mechanical structure of the circulating drying oven is enhanced is achieved, mechanical and flexible gear shifting is achieved, and a
piston rod conducts jacking push heating; the
processing quality of a whole belt is improved through gradual temperature increase and decrease of leather product drying, and the working efficiency is also improved; and after the internal environment is cooled through
wind power, the internal environment is continuously used, the working efficiency is improved, and the whole
mechanical integrity cooperation is efficient.
