Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Examples

The heat treatment drying device related in the prior art comprises a machine body 1, wherein a steam exhaust hole is formed in the top of the machine body 1, a first air suction device 3, more specifically an air suction cover, is arranged above the steam exhaust hole and can be communicated with an exhaust fan through a pipeline to suck wet air in the machine body 1. A drying device is provided inside the body 1. The drying device comprises a drying cylinder 4 and a plurality of rotating rollers positioned at the periphery of the drying cylinder 4. The rotating roller 5 is sleeved with a mesh belt 2, and the mesh belt 2 is contacted with the drying cylinder 4. The contact area of the mesh belt 2 and the drying cylinder 4 is at least half of the surface area of the drying cylinder 4.

After the fabric 6 is impregnated with the treatment liquid, it is rolled by a roll 11 to a predetermined liquid-carrying rate. After the fabric 6 is soaked, the fabric 6 passes through the space between the mesh belt 2 and the drying cylinder 4, the drying cylinder 4 and the mesh belt 2 clamp the fabric, so that the fabric 6 is in contact with the drying cylinder 4, the drying cylinder 4 with high temperature dries the fabric, and the moisture in the fabric can be emitted from the mesh belt. After the fabric 6 passes through the drying device, it is arranged above the drying device, and the fabric is discharged from the other side of the machine body 1. Since the first air suction device is located above the fabric 6, when the wet air is sucked, the wet air meets the fabric, so that the dried fabric 6 absorbs moisture again.

In order to solve the problem that the dried fabric absorbs moisture again, the fabric 6 is conveyed outside the machine. The present embodiment will be described in detail with reference to fig. 1 to 4.
