Belt type drying device with high evaporability

The belt type drying device comprises a support, a workbench and a driving motor, the workbench is fixedly installed above the support, and the driving motor is installed on the outer wall of the support through bolts; the first rotating shaft is connected with the output end of the driving motor, a second rotating shaft is arranged on the right side of the first rotating shaft, a third rotating shaft is arranged on the right side of the second rotating shaft, a fourth rotating shaft is arranged on the right side of the third rotating shaft, and meanwhile a fifth rotating shaft is arranged on the right side of the fourth rotating shaft. According to the belt type drying device with the high evaporability, when a cam extrudes a rubber air bag, air in the rubber air bag can enter a sleeve, so that a piston and a push rod are pushed to move, the push rod drives an extrusion block to move together, and therefore the extrusion block extrudes an oil storage bag body to conduct self-lubricating operation; manual ope
