Baking transmission mechanism

A baking transmission mechanism, comprising:

• a dustproof assembly including a box, a main transport wheel, a main conveyor belt and a drive unit, the main transport wheel and the drive unit being mounted on the box;
• a first transportation assembly including a first oven assembly, a first feed wheel, a first discharge wheel, a first pulley assembly and a second pulley assembly;
• the first feed wheel and the first discharge wheel located at a top of the first oven assembly, the first pulley assembly and the second pulley assembly located on opposite sides of the first oven assembly;
• and
• a second transportation assembly including a second oven assembly, a second feed wheel, a second discharge wheel and a third pulley assembly, the second feed wheel and the second discharge wheel located at the top of the second oven assembly, and the third pulley assembly adjacent to the second pulley assembly;
• and
• wherein the main conveyor belt is transported into the first oven assembly via the main transport wheel and the first feed wheel and is transported out via the first discharge wheel, and then is transported into the second oven assembly via the second feed wheel, and is transported out via the second discharge wheel;
• the transmission of the main conveyor belt is achieved by which the drive unit drives the first pulley assembly, the second pulley assembly and the third pulley assembly;
• wherein the first pulley assembly includes an upper pulley and a lower pulley coaxially arranged with the upper pulley;
• wherein the second pulley assembly includes an upper drive pulley and a lower drive pulley coaxially arranged with the upper drive pulley, the first oven assembly includes a first main driving shaft and three first driven shafts, the first main driving shaft includes a first rotation wheel and a first drive wheel, a first transmission belt is coiled around on the first rotation wheel and the upper pulley, a first convection belt is coiled around the first drive wheel and the lower drive pulley.
