Technical field
The utility model relates to a kind of composition system of the heat setting machine of printing and dyeing, and is specifically related to a kind of spray wind system of novel printing and dyeing heat setting machine, belongs to printing and dyeing heat setting machine technical field.
Background technology
Heat setting machine is the important equipment in dyeing process, and its major function is that the wet fabric to having dyeed carries out the processing such as airflow drying, stentering forming.Fabric is in dyeing course, need be via singing, preshrunk, move back boil float, the multiple tracks PROCESS FOR TREATMENT such as drying, mercerising, in processing procedure, fabric need stand the repeatedly warp-wise pulling force effect of machinery, and fabric warp-stretch, broadwise are shunk, and causes the phenomenons such as fabric width is irregular, weft yarn tilting.Heat setting process utilizes fabric to have extension characteristics just under dampness, under the certain tensile force of maintenance, by adopting high-temperature hot air to press it, thereby adjust through weft yarn the state in fabric, eliminate stress and the high elastic deformation of fabric, make high elastic deformation be converted into plastic deformation, guarantee that fabric settles out under new size.
In heat setting machine, high-temperature hot air is under fan action, after heat setting machine air blast beak, acts on fabric.The air blast beak action effect using on heat setting machine will be considered following factor: 1. when high temperature hot gas stream is dried, air blast beak quantity is various, between each air blast beak, exists and influences each other.2. need dry fabric thin and have pliability, when airflow drying, the speed of air-flow, direction and intensity directly affect the fixed effect of fabric.Because dry gas stream direct effect after air blast beak, to fabric, so the structure of air blast beak has a great impact fixed effect and sizing energy consumption, must carry out appropriate design to air blast beak.
The nozzle of the printing and dyeing heat setting machine of prior art is generally directly driveed on the base plate of air channel, and it is circular or square that nozzle cross-section mostly is.Because air channel base plate is generally thinner, therefore gas flow is shorter through the flow process of nozzle passage, cause the flow direction of air-flow after nozzle to disperse, smaller to the impact dynamics of fabric, thus penetrability is poor, and drying efficiency is not high; After the air-flow coupling of simultaneously flowing out from multiple nozzles, uniformity and the less stable of the airflow field forming at fabric upper and lower surface place, be unfavorable for the space suspension stability of fabric; Moreover because the uniformity of air-flow is poor, cause the heating temperature of zones of different of cloth inconsistent, easily cause the drying uniformity of cloth within the scope of fabric width poor, under severe case, can cause the problem such as surface color difference and shrinkage factor difference within the scope of cloth cover fabric width.
Therefore,, for solving the problems of the technologies described above, the necessary spray wind system that a kind of novel printing and dyeing heat setting machine is provided, to overcome described defect of the prior art.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model be a kind of simple in structure, drying efficiency is high and the spray wind system of the novel printing and dyeing heat setting machine of uniform drying.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of spray wind system of novel printing and dyeing heat setting machine, and it comprises air channel, air blast beak and baffle plate; Wherein, described air channel is made up of upper cover plate, end baffle and bottom baffle; On described bottom baffle, offer some installing holes; Described air blast beak is installed on installing hole; Described baffle plate is positioned at the below of bottom baffle, offers some dentation through holes on it; The center of described dentation through hole is consistent with the center of air blast beak.
The spray wind system of printing and dyeing heat setting machine of the present utility model is further set to: described air blast beak is venturi air blast beak, and all the height of air blast beak is consistent.
The spray wind system of printing and dyeing heat setting machine of the present utility model is further set to: described air blast beak is bolted on installing hole by screw thread.
The spray wind system of printing and dyeing heat setting machine of the present utility model is also set to: described upper cover plate, end baffle and bottom baffle are sheet metal component.
Compared with prior art, the utlity model has following beneficial effect: the spray wind system of printing and dyeing heat setting machine of the present utility model is simple in structure, dry gas stream is in acceleration and guide effect through venturi air blast beak, can guarantee vertically to act on fabric through the air-flow of air blast beak, improve the penetrability of air-flow, thereby promote HEAT SETTING drying efficiency; And by adopting dentation through hole, be conducive to upset the air-flow being reflected back through fabric, weaken gas eddy stream, guarantee the stable and uniform of fabric airflow field of living in, thereby guarantee its space suspension stability, guarantee the drying uniformity of fabric within the scope of fabric width, improve fabric sizing quality.

The specific embodiment
Refer to Figure of description 1 to shown in accompanying drawing 5, the utility model is a kind of spray wind system of novel printing and dyeing heat setting machine, and it is made up of several parts such as air channel 1, air blast beak 2 and baffle plates 3.
Wherein, described air channel 1 is made up of upper cover plate 11, end baffle 12 and bottom baffle 13.On described bottom baffle 13, offer some installing holes 14.And described upper cover plate 11, end baffle 12 and bottom baffle 13 are sheet metal component.
Described air blast beak 2 is installed on installing hole 14, and specifically, described air blast beak 2 is bolted on installing hole 14 by screw thread.This air blast beak 2 is venturi air blast beak, and all the height of air blast beak 2 is consistent.
Described baffle plate 3 is positioned at the below of bottom baffle 13, offers some dentation through holes 31 on it.Described dentation through hole 31 center is consistent with the center of air blast beak 2.These dentation through holes 31 are realized by punching press.
Fig. 5 is the design sketch of the spray wind system of printing and dyeing heat setting machine of the present utility model while carrying out HEAT SETTING: the hot blast that air blast blasts is interior in air channel 1 forms certain wind speed after air blast beak 2, and vertically act on the whole fabric width of wet fabric 4, realize the flatiron to fabric 4.Owing to being Venturi tube structure in air blast beak 2 inside, can accelerate the flow velocity of gas flow, thereby increase the penetrability of air-flow, and the guide effect of venturi air blast beak 2 to air-flow, can make steady vertical the blowing to and be in the fabric 4 of printing and dyeing heat setting machine from air nozzle exit of air-flow, thereby improve drying efficiency.
In addition, due to after the thermal current coming from air blast beak 2 acts on fabric 4, part air-flow can reflect and return, and produce gas eddy stream, so very easily cause the airflow field disorder on fabric 4, finally cause the irregular concussion of fabric within the scope of fabric width, increase the residual stress of fabric, destroy the planarization of fabric.Add after the baffle plate 3 that has dentation through hole 31, can play flow-disturbing effect to reflected gas stream, destroy vortex field, make the airflow field on fabric 4 more stable, even, thereby guaranteed the stable and uniform of fabric 4 residing airflow fields.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
