Segment 32, and the material is further divided into two in each of the second splitters 32, and finally output by four of the second splitter outlets 36.

According to the above description, it is known that due to the adjacent two shunt layers, the total number of the shunt segments of the previous shunt layer to the second shunt layer is increased in an equal manner, and the distance from the inlet to the nozzles can be shortened. In this way, it is possible to solve the conventional problem that the flow rate of the foaming material flow distribution nozzle is too large due to the long stroke of the inlet port to each nozzle.

Figure 3 is a view showing a foaming material flow distribution nozzle according to a second embodiment of the present invention, the main structure of which is the same as that of the first embodiment, except that the ratio-type diverting piping system 20 has a third diversion. Layer 40.

The third split inlet 44 of the third splitter section 42 of the third splitter layer 40 is correspondingly connected to the second splitter outlet 36 of the second splitter section 32 of the second splitter layer 30. The distance between the third split inlet 44 and the third split outlet 46 is equal. Each of the nozzles 38 is mounted to each of the third branch outlets 46 of the third splitter layer 40.

It can be inferred from the first embodiment and the second embodiment that the equal-divided diverting piping system 20 sequentially includes the first to m-th shroud layers, wherein the m-th shunt layer has r ^{m- 1} mth diversion section. Each of the split sections of each of the split layers has a split inlet and an r split outlet, and the distance from the split inlet to each of the split outlets is equal.

And each of the splitter sections has a split inlet and a splitter outlet, and can be calculated by substituting the above formulas: the fourth splitter layer 50 of the proportional split line system 20 has eight fourth split sections 52, And sixteen fourth split outlets 54 such that sixteen of the nozzles 38 are mounted to each of the fourth split outlets 54, respectively.

Referring to Figure 5, in actual use, a portion of material (foaming material) 90 entering from the first splitter section 24 is divided into two portions of material 90, and then divided into two portions of material 90 by two portions of material 90, Since the output of the material 90 from each of the nozzles 38 is equal, when the flat plate 92 is sprayed, the material (foaming material) 90 can be sprayed stably and uniformly on the surface of the flat plate 92.

In the relevant formula of the foregoing proportional splitting piping system 20, when r is three (each splitting section has three splitting outlets), and m is two, the foaming material flow distribution nozzle system includes a first splitting layer And a second diversion layer, and the second diversion layer has nine second diversion outlets, so that nine nozzle systems are respectively installed at the respective second diversion outlets.

Referring to FIG. 6, a foaming material flow distribution nozzle according to a fourth embodiment of the present invention is different from the first embodiment in that each of the diverting sections 80 of the proportional diverting piping system 20 Have different widths.

Each of the splitter sections 80 located in the mth layer has the first splitter passage 801 and the second splitter passage 802. The first shunting channel 801 is connected to the shunting outlet of the previous shunt layer (m-1) and the shunting inlet of the next shunt layer (m+1); similarly, the second shunting channel 802 is The split outlet of the previous split layer (m-1) and the split inlet of the next split layer (m+1) are joined.

The first shunt passage 801 is connected to the split outlet of the previous split layer, and the second split passage 802 is connected to the split outlet of the previous split layer, and the so-called "diverted outlet of the previous split layer" is the same Further, the first shunting channel 801 is connected to the shunting inlet of the second shunt layer, and the second shunting channel 802 is connected to the shunting inlet of the second shunting layer, and the so-called "diverting inlet of the second shunting layer" is different. Diversion entrance.

In this embodiment, in particular, the width of the first shunt channel 801 is designed to be smaller than the second shunt channel 802, so that the channel cross-sectional area of the first shunt channel 801 is smaller than the channel of the second shunt channel 802. Cross-sectional area. In actual use, each of the split outlets of the last split layer is coupled to the nozzle for providing the purpose of discharging the foamed material, and each of the split sections can be planned to have different widths or depths according to the required cross-sectional dimensions of the finished product. In order to achieve the demand for the raw material to be discharged according to the position of the finished section.

The nozzle 38 of the first shunt passage 801 of the area is opposite to the flat portion 98, and the nozzle 38 of the second shunt passage 802 having a larger cross-sectional area is opposite to the recess 96, due to the second shunt passage 802 The channel width is greater than the channel width of the first branching channel 801, so that the spraying amount of the material (foaming material) 90 in the groove 96 is larger than the spraying amount of the material 90 on the surface of the plane portion, so that the surface structure of the finished product can be obtained. The effect of ejecting the corresponding flow rate causes the material (foaming material) 90 at each position of the wave plate 94 to have a uniform height after expansion to avoid uneven expansion of the foam layer of the wave plate 94.

It can be seen from the above embodiments that, when the raw materials are introduced into the equal-divided diverting pipeline system 20 to the same distance of the nozzles 38, the flow velocity of the material in each diverting section is also the same, except The problem of blockage caused by the conjunctiva in the split section due to the slow flow rate of the material may occur, and the service life of the foam flow distribution nozzle may be prolonged. In addition, this creation can be used for low-pressure gas-jet mixing, which can reduce equipment costs and achieve lower cost.
