[0039] Working principle:

[0040] The device makes wind curtains at both ends of the casing 4 through the air curtain machine 3, and the wind curtains form a relatively closed environment, effectively blocking the heat leakage in the first accommodating groove 403. The hot air circulates in the casing 4, and after being heated by the electric heating tube 6, the temperature of the hot air rises, and the diaphragm body 2 is dried.

[0041] The electric heating tube 6 is installed in the second accommodating groove 404 of the casing 4 and supported by the support 7. When the electric heating tube 6 is powered on, heat will be generated, which is transferred to the diaphragm body 2 by the hot air. The partition 402 evenly divides the first accommodating groove 403 into two parts, but the through hole 405 allows the hot air to flow freely between the two parts, thereby realizing the uniform distribution of heat.

[0042] The diaphragm body 2 is tightly supported by the upper support roller 1 and the lower support roller 5, and these support rollers not only support the weight of the diaphragm, but also ensure the stability of the diaphragm during drying. The upper support roller 1 is symmetrically distributed on both sides of the lower support roller 5, so that the diaphragm body 2 can smoothly pass through the two first accommodating grooves 403 of the casing 4 and receive uniform drying.

[0043] During the drying process, the hot air continuously circulates and transfers the heat generated by the electric heating tube 6 to the diaphragm body 2. With the continuous blowing of hot air and the continuous heating of electric heating, the moisture in the diaphragm body 2 is gradually evaporated, thereby achieving the purpose of drying.
