Problems solved by technology

Because the thickness of the metal sheet is relatively thin (usually around 0.15mm), it often occurs that the sheet is deformed due to excessive wind pressure during air drying; Both lead to the problem that some areas of the metal sheet cannot be completely dried

Embodiment

[0027] Example: see attached figure 1 As shown, a metal thin plate drying equipment includes a closed drying cavity 1, the metal thin plate is placed in a product carrier 2 after cleaning, and is sent into the drying cavity 1 through an assembly line 3 for drying. dry.

[0028] It also includes a hot air circulation motor 4, which heats the air supply through a heating box 5 and then blows the hot air into the drying cavity 1 from top to bottom through the air outlet pipeline 6; the heating method of the heating box 5 Including but not limited to existing heating technologies such as resistance wire heating and electromagnetic heating; in addition, a return air pipeline (not shown in the figure) can also be provided in the drying chamber 1, and the return air pipeline returns the hot air through negative pressure. To hot air circulation motor 4, to realize the circulation of air-flow.

[0029] Wherein, the air outlet 7 of the air outlet pipeline 6 is provided with a pluralit...

Abstract

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 uniform, parts of the metal sheet can be fully dried. The drying equipment has the advantages of being high in drying efficiency and good in drying effect.

Description

technical field [0001] The invention relates to the field of sheet metal processing, in particular to a drying device for a cleaned metal sheet. Background technique [0002] In the sheet metal processing process of metal sheets, automatic ultra-microwave cleaning is required after punching and cutting processes such as punching and crimping, and heating and drying after cleaning. Generally, drying equipment is used in the heating and drying process. However, the existing drying equipment has the following shortcomings when used: [0003] When the existing drying equipment performs the drying operation, most of them increase the flow rate of the air on the surface of the metal sheet by blowing to accelerate the evaporation of water vapor. Because the thickness of the metal sheet is relatively thin (usually around 0.15mm), it often occurs that the sheet is deformed due to excessive wind pressure during air drying; Both lead to the problem that some areas of the metal sheet ...
