Abstract

The utility model relates to a dyeing machine nozzle with an improved structure, which comprises a nozzle body, an internal diameter of a water guide opening of which is probably elliptical; the front and the back sides of the nozzle body are linear, parallel and symmetrical; the left and the right sides are symmetrical in a circular arc shape, and according to the relative proportion, the internal diameter of an inlet of the body above the water guide opening is probably elliptical and is in the reducing state from top to bottom. When spraying and dyeing are conducted, the utility model has the advantage of no dead angles, when the piece goods pass through the utility model, the piece goods can also not be twisted to be a rope shape.

Description

Structure improved dyeing machine nozzle

The utility model relates to a kind of dyeing machine, and relating in particular to does not a kind ofly have the spray-painting dead angle, and cloth by the time also can not reverse the structure improved dyeing machine nozzle that is rope form.

Employed normal temperature of ordinary stain factory or high temperature rapid dyeing machine, the principle of its dyeing mainly is to borrow dye liquor that nozzle sprayed and cloth to contaminate in the groove to circulate, to reach Color.The quality of dyeing quality wherein, about 70～80% depend on the effect of nozzle, and the effect that staining bath is contaminated for cloth only accounts for about 20%～30%.Hence one can see that, and nozzle is for the importance of dyeing machine, the engine in automobile, so, the success or failure of piece dyeing, the design of nozzle and function are occupied very big factor.

Commonly use the employed nozzle of dyeing machine, mainly be divided into two big classes, first kind is rectangular nozzle (being commonly referred to as flood nozzle); Another kind of is round nozzle (being commonly referred to as spout nozzles).When yet it contaminates the engineering use in reality, its inevitable shortcoming is arranged all, conjunction with figs. narration now as back:

As shown in Figure 1 to Figure 3, for commonly using the schematic diagram of round nozzle, this round nozzle (1) current are injected by ring-type water guide mouth (11), the dye liquor that it sprayed is to be inverted cone-shaped and to intersect at a point, as shown in Figure 3, the flow that this spout nozzles characteristics are water is little and pressure is big, thereby it is big and speed is fast to drive the strength of cloth (C).The dye liquor that but its shortcoming is this nozzle to be sprayed is to intersect a bit, though therefore having bigger hydraulic pressure can drive cloth (C) cycle operation, also thereby cause cloth (C) to reverse and be rope form, more easily forms the straight line CREASE MARK, is its disadvantage.

Again, Fig. 4 is to shown in Figure 6, for commonly using the schematic diagram of rectangular nozzle, the water guide mouth (21) of this rectangular nozzle (2) is to be rectangle, the intersection location of the current that its both sides sprayed is (wire) generally in the form of sheets, as shown in Figure 6, rather than is point-like, its characteristics are that the flow of water is big and pressure is little, therefore cloth is difficult for being rope form, can form jet flow " dead angle " but its shortcoming is the place, angle of respectively holding of rectangular nozzle, so herein the cloth (C) of flowing through, it is even to be difficult for spray-painting, is its disadvantage.

This creator is because commonly use round nozzle or all there is inevitable shortcoming in rectangular nozzle, so actively seek to improve at problem points.

Main purpose of the present utility model is, a kind of structure improved dyeing machine nozzle is provided, and the water guide mouth internal diameter of this nozzle is generally to be an oval body, and makes that its forward and backward both sides are the straight line parallel symmetry shape, and again, and arranged on left and right sides is the circular arc symmetry shape; The body inlet of water guide mouth top, its internal diameter is also pressed the general ovalize body of relative scale of water guide mouth internal diameter, and from top to bottom is the convergent state, whereby, has the advantage at no dead angle during its spray-painting, and cloth by the time also can not reverse and be rope form.

The purpose of this utility model is realized by following technical scheme.

A kind of structure improved dyeing machine nozzle, comprise a nozzle body, it is characterized in that, the water guide mouth internal diameter of this nozzle body generally is an oval body, and make that its forward and backward both sides are the straight line parallel symmetry shape, and arranged on left and right sides is the circular arc symmetry shape again, the body inlet of water guide mouth top, its internal diameter is also according to the general ovalize body of the relative scale of water guide mouth internal diameter, and from top to bottom is the convergent state.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Fig. 1 is a stereoscopic schematic diagram of commonly using round nozzle.

Fig. 2 is a cutaway view of commonly using round nozzle.

Fig. 3 is the schematic diagram of 3-3 section shown in Figure 2.

Fig. 4 is a stereoscopic schematic diagram of commonly using rectangular nozzle.

Fig. 5 is a cutaway view of commonly using rectangular nozzle.

Fig. 6 is the schematic diagram of 6-6 section shown in Figure 5.

Fig. 7 is the cutaway view of the utility model preferred embodiment.

Fig. 8 is the schematic diagram of 8-8 section shown in Figure 7.

Fig. 9 is the schematic diagram of 9-9 section shown in Figure 7.

At first, see also shown in Fig. 7,8,9, the modified form nozzle (3) that the utility model disclosed is characterized in that:

Water guide mouth (31) internal diameter of this nozzle (3) generally is an oval body, and makes its forward and backward both sides (F), (B) be the straight line parallel symmetry shape, and again, and arranged on left and right sides (L), (R) are the circular arc symmetry shape; The body inlet (32) of water guide mouth (31) top, its internal diameter is also pressed the general ovalize body of relative scale of water guide mouth (31) internal diameter, and from top to bottom is the convergent state.

By above-mentioned feature, the utility model is when spray-painting cloth (C), and the dye liquor or the current of its forward and backward line part branch ejection can be wire (sheet) and intersect, but not intersect a bit, are rope form so cloth (C) can not reverse.In addition, the circular arc portion of and arranged on left and right sides (L), (R) also carry out spray-painting to the end angle of cloth (C), so without any the dead angle.So, by ingenious design of the present utility model, commonly use the shortcoming of rectangular nozzle and round nozzle, and the advantage that captures both is blended in all over the body and forgo fully, be one to have the new type nozzle of progressive.

In sum, the structure that the utility model disclosed by former times is not had, and really can reach the effect of expection, and has and can supply industry applications, meets novel patent requirement fully.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
