Dry-wet separation-type preshrinking device

Abstract

The invention discloses a dry-wet separation-type preshrinking device. The device includes a preshrinking mechanism, and a wetting mechanism and a drying mechanism are arranged on the two sides of thepreshrinking mechanism respectively; the wetting mechanism includes a wetting box body, and the internal space of the wetting box body is provided with a first transmission roller, a second transmission roller, a third transmission roller and a fourth transmission roller which are arrayed staggeredly; a first vapor sprayer and a second vapor sprayer are arranged on the front and rear sides of theplane where the second transmission roller and the third transmission roller are positioned. The preshrinking mechanism includes a preshrinking box body, and the preshrinking box body is internally provided with a fabric flattening device and a preshrinking mechanism body; the fabric flattening device comprises a lower shell body and an upper shell body, a fifth transmission roller is arranged inthe lower shell body, multiple groups of flattening wheels are arranged in the upper shell body, and the axial directions of the flattening wheels are spatially intersected with the fifth transmission roller. The device has the advantages that fabric can be thoroughly wetted, the preshrinking effect of the fabric is great, and the service life of the device is long.

Description

technical field [0001] The invention relates to a pre-shrinking device, in particular to a dry-wet separation type pre-shrinking device. Background technique [0002] The fabric pre-shrinking device is an indispensable finishing equipment in the modern garment production process of textile machinery. After the fabric is pre-shrunk, the shrinkage rate can be stabilized, and the quality and dimensional stability of the fabric can be further improved. The existing fabric pre-shrinking generally uses steam Steam pre-shrinking is designed according to the principle of fiber heat shrinkage; however, the existing fabric pre-shrinking device is often used to wet, pre-shrink, and dry fabrics in the same box, and a spraying mechanism is set above the hot roller of the pre-shrinking mechanism. Wetting the fabric, this design makes the whole box in a humid environment, which greatly affects the service life of each internal component, and the fabric is also poorly moistened, and the fab...

[0002] The fabric pre-shrinking device is an indispensable finishing equipment in the modern garment production process of textile machinery. After the fabric is pre-shrunk, the shrinkage rate can be stabilized, and the quality and dimensional stability of the fabric can be further improved. The existing fabric pre-shrinking generally uses steam Steam pre-shrinking is designed according to the principle of fiber heat shrinkage; however, the existing fabric pre-shrinking device is often used to wet, pre-shrink, and dry fabrics in the same box, and a spraying mechanism is set above the hot roller of the pre-shrinking mechanism. Make the fabric wet, this design makes the whole box in a humid environment, which greatly affects the service life of each internal component, and the fabric moistening effect is also poor, and the fabric is often not wet evenly, resulting in poor pre-shrinking effect

Therefore, the existing pre-shrinking device has the problems that the fabric cannot be fully wetted, the pre-shrinking effect of the fabric is poor, and the service life of the device is short.
