Drying equipment for metal sheet

The invention relates to drying equipment for a metal sheet. The drying equipment comprises a drying cavity. A hot air circulating motor heats blown air through a heating box body and blows the hot air into the drying cavity from top to bottom through an air outlet pipeline. A plurality of air outlets of the air outlet pipeline are uniformly formed in the upper part of the drying cavity, so that primary pre-drying air outlet, secondary drying air outlet and third dry air outlet are achieved. The drying equipment also comprises a wind direction adjusting device arranged corresponding to the airoutlets. The wind direction adjusting device comprises a wind direction adjusting plate which is composed of a plurality of guide plates which are horizontally spaced and arranged obliquely. Guide air ducts are formed between adjacent guide plates. As the air outlet pressure and temperature are relatively low, the metal sheet is not deformed, and meanwhile, as many air outlet directions are available and blow air is unif
