[0035] The working principle of the present utility model is as follows: When it is necessary to air-dry the ink on the surface of the photovoltaic glass filaments, the user places the photovoltaic glass filaments inside the placement plate, then fixes them inside the placement plate through the limiting plate, and starts the driving motor 9 through the external controller. The driving motor 9 drives the first rotating rod 4 to rotate, the first rotating rod 4 drives the first pulley 10 to rotate, the first pulley 10 drives the second pulley 11 to rotate, and the second pulley 11 drives the second rotating rod 5 to rotate.

The push rod 18 drives the piston plate 16 to move to the right and compresses the spring 17. At this time, the first one-way valve 24 closes and the second one-way valve 25 opens, so the air inside the ventilation pipe 13 flows into the drying chamber 1. When the pushing block 21 separates from the inclined block 19, the spring 17 rebounds through its own elasticity and pushes the piston plate 16 to move to the left. At this time, the first one-way valve 24 opens and the second one-way valve 25 closes, so as to suck the outside air into the inside of the ventilation pipe 13. Repeating this way can achieve the purpose of reciprocating piston. Coupled with the settings of the first one-way valve 24 and the second one-way valve 25, the flow of air can be accurately controlled, so as to achieve the purpose of ventilating the inside of the drying chamber 1, ensure the dryness of the internal air, and increase the air-drying efficiency.
