The pre-wetting apparatus of a kind of preshrinking machine
Technical field
The present invention relates to a kind of preshrinking machine, particularly a kind of pre-wetting apparatus for preshrinking machine.
Background technology
Printing and dyeing enterprise, on tinuous production, before carrying out preshrinking machine process to cloth, needs to use steam to carry out in advance to wet process cloth.But existing pre-dewing is all clothes that steam jet is directly sprayed in linear transmission by employing.This mode not only cannot accomplish that dewing is even, but also can cause very large waste to steam.
Summary of the invention
The object of the invention is to, provide a kind of preshrinking machine pre-wetting apparatus.It can carry out even dewing to cloth before cloth preshrinking, and energy-conserving and environment-protective more.
Technical scheme of the present invention: the pre-wetting apparatus of a kind of preshrinking machine, be characterized in: comprise dewing casing, dewing box house is provided with multiple top transfer roller side by side and multiple bottom transfer roller side by side, described dewing casing both sides are respectively equipped with import and the outlet of cloth, and import and outlet are all positioned at the top of dewing body side; Described dewing box house is provided with two dewing pipes, and two dewing pipes lay respectively at the both sides in dewing casing; Described dewing pipe horizontal positioned, and parallel with bottom transfer roller with top transfer roller; Described dewing pipe comprises the interior pipe in an outer tube and outer tube, and the side near dewing casing center on outer tube offers axial slit, and the side near dewing wall box on interior pipe offers axial slit.Namely the slit of outer tube is towards cloth cover.
In the pre-wetting apparatus of above-mentioned preshrinking machine, described outer tube is identical with the slit width on interior pipe.
Compared with prior art, the present invention by using dewing casing, and arranges transfer roller bottom, top transfer roller in dewing casing, and cloth can be made to send in the back pass of dewing casing infolding; Coordinate two dewing pipes that water vapour can be made to carry out twice dewing to cloth again, and unnecessary steam is closed in the dewing that dewing casing carries out slow immersion.And dewing pipe of the present invention is the structure of inside and outside two-layer, in conjunction with the slit that both direction is different, final steam can be made to penetrate with uniform air flow, and there is higher penetrability.Therefore, the present invention when carrying out dewing to cloth, not only more evenly, thorough but also energy-conserving and environment-protective more.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Being labeled as in accompanying drawing: 1-dewing casing, 2-top transfer roller, 3-bottom transfer roller, 4-cloth, pipe in 5-, 6-outer tube.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
Embodiment.The pre-wetting apparatus of a kind of preshrinking machine, as shown in Figure 1: comprise dewing casing 1, dewing casing 1 inside is provided with multiple top transfer roller 2 side by side and multiple bottom transfer roller 3 side by side, described dewing casing 1 both sides are respectively equipped with import and the outlet of cloth 4, and import and outlet are all positioned at the top of dewing casing 1 side; Cloth alternately walks around top transfer roller 2 and bottom transfer roller 3 in dewing casing 1.Described dewing casing 1 inside is provided with two dewing pipes, and two dewing pipes lay respectively at the both sides in dewing casing 1; Described dewing pipe horizontal positioned, and parallel with bottom transfer roller 3 with top transfer roller 2; Described dewing pipe comprises the interior pipe 5 in an outer tube 6 and outer tube 6, and the side near dewing casing 1 center on outer tube 6 offers axial slit, and the side near dewing casing 1 sidewall on interior pipe 5 offers axial slit.Described outer tube 6 is identical with the slit width on interior pipe 5.
During work, pipe 5 in steam is communicated with, the steam in interior pipe 5 blows between two pipes through slit, finally turn back to the slit of outer tube 6 and outgoing to cloth cover, this structure can make steam more even, and the vapor transmission power of outgoing strengthens.
