Description

Nozzle structure for multifilament entanglement and cohesion

technical field

The invention relates to a nozzle structure for entanglement and coagulation of multifilaments, in particular to a nozzle structure for entanglement and cohesion of multifilaments with a faster and more stable gas flow rate.

Background technique

Generally, filament yarns need so-called air treatment after the spinning process, so that individual filaments can be held together more firmly. Among them, the nozzles generally used for multifilament entanglement and cohesion will have a thread channel for carrying the thread and a gas channel for the gas to pass through. The air flow rate in the gas channel will also be closely related to the knotting ability of the thread.

The current existing nozzle structures can be shown in Figures 1 to 7. Figures 1 to 4 are schematic cross-sectional views of nozzles currently available on the market. Figure 1 is the most convenient nozzle configuration. The gas channel 2 is connected to the silk channel 1 in a straight line, so it does not have any effect of changing the air flow rate. The main difference in Figure 2 is that the gas channel 2 is set to taper toward the thread channel 1, but this configuration also has a limited impact on the air flow rate, and the configurations in Figure 1 and Figure 2 do not have an integrally formed air chamber, so usually an additional air chamber is connected during use to allow the air to have a buffering effect, but such an additionally connected air chamber will not only greatly increase the possibility of air leakage, but also more troublesome during installation.

Although the integrally formed air chamber area 3 is connected in Fig. 3, the gas passage 2 in this form is also connected to the thread passage 1 in a straight manner, so the influence on the air flow rate is also limited. Although Fig. 4 also has an integrally formed gas chamber area 3, the gas channel 2 is only connected to the silk channel 1 through a gradually expanding state, which naturally has a limited influence on the air flow rate. Furthermore, since there is no guiding effect between the gas chamber area 3 and the gas channel 2 in Fig. 4 and Fig. 5, it is easy for the gas to flow as shown in the direction of the arrow, resulting in rebound or obstruction.

FIG. 5 is a schematic cross-sectional view of the nozzle of US Patent No. US4535516. Although there is an air chamber area 3 and a special-shaped gas channel 2 to connect the thread channel 1, since the air chamber area 3 is also an additional structure, it also has the disadvantages of the above-mentioned aspects of FIGS. 1 and 2.

Figure 6 is a schematic cross-sectional view of the nozzle of Taiwan Patent Publication No. 503272. Although there is a special-shaped gas channel 2 to connect the thread channel 1, it does not have an integrally formed air chamber, so it does not have the effect of allowing air to buffer. If an additional air chamber is to be installed, there may also be a possibility of air leakage.

Fig. 7 is a schematic cross-sectional view of the nozzle of Taiwan Patent Publication No. M406616, in which although there is an integrally formed air chamber area 3, the gas channel 2 connected to the thread channel 1 is only tapered in the direction of the thread channel 1, so the influence on the air flow rate is also limited.

However, the above-mentioned nozzles have the following problems and deficiencies that need to be improved when they are used: they cannot simultaneously have an integrally formed air chamber that can reduce the possibility of air leakage, and a gas channel that can increase the gas flow rate.

Therefore, how to solve the above-mentioned existing problems and deficiencies is the direction that the applicant of the present invention and related manufacturers engaged in this industry want to study and improve.

The main purpose of the present invention is to reduce the possibility of air leakage through the integrally formed air chamber area, and to increase the air flow rate by cooperating with the gas channel of the Delaware nozzle.

With the above-mentioned structure, when in use, the silk thread can be placed in the thread channel, and the air can be introduced into the air chamber area. When the gas is in the air chamber area, it can produce a buffering effect. Combined with the tapering and guiding effect from the inlet end to the narrow tube part, the air can flow into the gas channel smoothly. Make the supply air source more stable to obtain uniform multifilament entanglement and cohesion effect.

By means of the above-mentioned technology, a breakthrough can be made to solve the problems of poor air flow rate of the existing nozzles or easy air leakage, so as to achieve the practical progress of the above-mentioned advantages.

Please refer to Fig. 3, Fig. 4, and Fig. 8 to Fig. 11, which are schematic sectional views (three) and schematic sectional views (four) of the existing nozzle, and the perspective view of the first embodiment of the present invention to the flow schematic view of the nozzle. It can be clearly seen from the figure that the nozzle N of the present invention mainly includes:

At least one thread channel 1, the cross section of the thread channel 1 in this embodiment forms a U-shaped pattern;

At least one gas channel 2 connected to the thread channel 1;

At least one gas chamber region 3 at one end of the different thread channel 1 connecting the gas channel 2;

at least one inlet port 21 formed in the gas channel 2 and located at one end connected to the gas chamber area 3;

At least one gas outlet 23 formed in the gas channel 2 and located at one end of the connecting thread channel 1;

at least one narrow tube portion 22 formed in the gas channel 2 and located between the gas inlet end 21 and the gas outlet end 23;

a guide inclined surface 211 formed between the narrow tube portion 22 and the inlet end 21;

At least one air chamber communicating end 31 formed in the air chamber area 3 and located at one end connected to the inlet end 21;

At least one air chamber inlet port 32 is formed in the air chamber area 3 and is located at one end of the different air chamber communication ends 31, and the width d1 of the narrow tube portion 22 will be smaller than the width d0 of the air outlet end 23 and the width d2 of the inlet end 21, and the width d3 of the air chamber communication end 31 will be greater than the width d2 of the air inlet end 21, and the width d4 of the air chamber inlet end 32 will be greater than or equal to the width d3 of the air chamber communication end 31.

When the nozzle N of this case is used, the nozzle N will be arranged in a fixed housing 4, and the silk thread will be placed in the thread channel 1, and the air chamber area 3 can be connected to the structure of the gas supply, so that the gas can be introduced into the nozzle N to perform blowing action on the thread, and the material of the nozzle N in this embodiment is one of ceramics or metal.

The gas will first enter the gas chamber region 3 from the gas chamber inlet port 32 to achieve the buffering effect, and then be introduced into the gas channel 2 from the gas chamber connecting port 31, and because the gas chamber region 3 in this case is integrally formed in the nozzle N, there will be no various types of connection parts, and there will be no chance of gas leakage at the connection parts, so the pressure will not drop when the gas flows.

And before the gas enters the gas channel 2, it will be in a state of tapering from the inlet end 21 to the narrow tube part 22, so that when the gas passes through, it can enter the gas channel 2 along the guide slope 211, so that the air flow can be smoother, so as to reduce the flow resistance. And because the direction of the gas channel 2 from the inlet end 21, the narrow pipe portion 22, to the gas outlet end 23 will first taper and then gradually expand, so that the effect of the Delaware nozzle can be produced. The so-called Delaware nozzle uses an asymmetrical hourglass-shaped tube that shrinks in the middle, and by the principle of converting the heat energy of the fluid into kinetic energy, the gas passing through the Delaware nozzle is accelerated to a supersonic speed, and the gas can just reach the speed of sound at the point where the cross-sectional area is the smallest. It has been widely used in steam turbines and rocket engine nozzles, and can also be found in supersonic jet engines.
