Section 32, and the material is further divided into two parts in each of the second branching sections 32, and finally output by four second branching outlets 36 at the same time.

According to the above description, it is known that due to the adjacent two split layers, the total number of split sections from the previous split layer to the next split layer is increased in a proportional manner, which can shorten the distance from the inlet to each nozzle, In this way, it is possible to solve the problem that the conventional flow path of the foam inlet is too large due to the long stroke from the inlet to each nozzle.

FIG. 3 shows the foam material flow distribution nozzle provided by the second embodiment of the present invention. Its main structure is the same as that of the first embodiment, and the difference is that the proportional splitting piping system 20 further has a third splitting Layer 40.

The distance from the third splitter inlet 44 to the second splitter outlet 46 is equal. Each of the nozzles 38 is attached to each of the third branch outlets 46 of the third branch layer 40.

It can be inferred from the first embodiment and the second embodiment that the proportional shunt piping system 20 sequentially includes the first shunt layer 22 to the m-th shunt layer, where the m-th shunt layer has r ^{m- 1} m-th shunt section. Each shunt section of each shunt layer has a shunt inlet and an r shunt outlet, and the distance from the shunt inlet to each of the shunt outlets is equal. In the two adjacent shunt layers, the shunt outlets of the shunt sections in the previous shunt layer respectively correspond to the shunt inlets of the shunt section in the next shunt layer. Where m is a natural number, r is a natural number and is greater than or equal to two, and the number of shunt outlets in the ^m- th shunt layer is r ^m . Each of the nozzles 38 is attached to each of the branching outlets of the mth branching layer.

For example, if the proportional split piping system 20 includes a first split layer 22 to a fourth split layer 50 , And each of the shunt sections has one shunt inlet and two shunt outlets, it can be calculated by substituting the above formulas: the fourth shunt layer 50 of the proportional shunt piping system 20 has eight fourth shunt sections 52, There are sixteen fourth diverter outlets 54, so that there are sixteen nozzles 38 respectively installed in the fourth diverter outlets 54.

Please refer to FIG. 5, in actual use, after one part of the material (foamed material) 90 entered from the first diverting section 24 is divided into two parts of the material 90, then the two parts of the material 90 are divided into four parts of the material 90, because The output amount of the material 90 from each nozzle 38 is equal, so when spraying a flat plate 92, the material (foam material) 90 can be stably and uniformly sprayed on the surface of the flat plate 92.

The first shunt channel 801 is connected to the shunt outlet of the previous shunt layer (layer m-1) and the shunt inlet of the next shunt layer (layer m+1); similarly, the second shunt channel 802 and The shunt outlet of the previous shunt layer (layer m-1) and the shunt inlet of the next shunt layer (layer m+1) are connected.

The aforementioned first shunt channel 801 is connected to the shunt outlet of the previous shunt layer, and the second shunt channel 802 is connected to the shunt outlet of the previous shunt layer. The so-called "shunt outlet of the previous shunt layer" is the same ; And, the first shunt channel 801 is connected to the shunt inlet of the next shunt layer, and the second shunt channel 802 is connected to the shunt inlet of the next shunt layer, the so-called "shunt inlet of the next shunt layer" is different Shunt inlet.

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 shunt outlets of the last shunt layer is matched with the nozzle for the purpose of spraying foamed material, and each of the shunt sections can be planned with different widths or depths according to the needs of the cross-sectional size of the finished product , In order to achieve the demand of the raw material to spray the corresponding flow rate according to the cross-sectional position of the finished product.

For example, when the present invention is used to spray a wave plate 94, the wave plate 94 has a plurality of grooves 96, and there is a plane portion 98 between the grooves 96, which is connected The nozzle 38 of the area of the first branching channel 801 is opposite to the plane portion 98, and the nozzle 38 of the second branching channel 802 having a larger cross-sectional area is opposite to the groove 96, because the second branching channel 802 The channel width is larger than the channel width of the first split channel 801, so that the spraying amount of the material (foamed material) 90 in the groove 96 is greater than the spraying amount of the material 90 on the surface of the flat portion, so that it can have a surface structure according to the finished product The effect of spraying the corresponding flow rate, so that the material (foaming material) 90 at each position of the wave plate 94 can have a uniform height after expansion, so as to avoid uneven expansion of the foam layer of the wave plate 94.

It is known from the above embodiments that when the distance between the raw material introduced into the proportional split piping system 20 and each nozzle 38 is the same, the flow velocity of the material in each split section is also the same, except for It will cause the problem of congestion caused by the conjunctiva in the shunt section due to the slow flow rate of the material, and the service life of the foam material flow distribution nozzle can be extended. In addition, this creation can be used in the spraying method of low-pressure gas spray mixing, which can reduce the cost of equipment and achieve the purpose of lower cost.
