Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a spray plate for generating composite yarns. Background Art

[0002] In the production process of synthetic fiber filaments, most of them use the melt spinning process. The function of the spinning assembly is to filter and mix the spinning melt, so that the melt is extruded through the micropores of the spinneret at high pressure to form filaments. Among them, the various parts of the spinning assembly are responsible for distributing the melt, filtering and mixing the spinning melt.

[0003] After searching, the applicant found that a Chinese patent disclosed "a composite spinneret" with the publication (announcement) number "CN209292519U". This patent mainly uses a guide groove to allow the spinning melt to flow into the first flow hole for spinning. However, the first flow hole can only extrude and spin one type of spinning melt at a time, and it is difficult to mix and spin two spinning melts of different properties. For this reason, we propose a spinneret for generating composite yarns. Utility Model Content

[0004] The purpose of the utility model is to provide a spray plate for generating composite yarn.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spray plate for composite silk generation, comprising a support frame, the inner wall of the support frame is slidably connected to two spray plate bodies, the opposite sides of the two spray plate bodies are overlapped, and the opposite sides of the two spray plate bodies together constitute a plurality of spinneret holes, the inner wall of the support frame is slidably connected to a diverter block, the inner wall of the support frame is fixedly connected to a limiting strip, the right side of the support frame is overlapped with a cover plate, a liquid storage chamber is formed between the diverter block and the spray plate body, the right side of the cover plate is fixedly connected to a connecting valve, and the left end of the connecting valve passes through the left side of the cover plate and is connected to the liquid storage chamber.

[0006] As a further solution of the present invention: a limiting groove is provided on the lower end surface of the diverter block, and the side surface of the limiting strip is slidably connected to the inner wall of the limiting groove.

[0007] As a further solution of the present invention, the diverter block can be configured in two shapes: solid and hollow.

[0008] As a further solution of the present invention: the shape of the limiting strip matches the shape of the limiting groove.

[0009] As a further solution of the present invention: a first threaded rod is threadedly connected to the cover plate and the spray plate body, and a second threaded rod is threadedly connected to the support frame and the spray plate body.

[0010] As a further solution of the present invention: the left side of the cover plate abuts against the right side of the spray plate body, and the left side of the cover plate abuts against the right side of the diverter block.

[0011] As a further solution of the present invention: the shape of the side surface of the spray plate body matches the shape of the inner wall of the support frame.

[0012] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model combines two nozzle plate bodies together and installs a diverter block between the two nozzle plate bodies, so that two or three different spinning melts can be extruded through the spinneret. The staff can select the diverter block according to the specific situation, and can fuse two or three spinning melts with different properties together, thereby enriching the characteristics of the extruded filaments;

[0014] 2. The utility model can realize the disassembly of the cover plate through the first threaded rod.

A liquid storage chamber is formed between the block 9 and the spray plate main body 2. The right side of the cover plate 4 is fixedly connected to a connecting valve 6. The left end of the connecting valve 6 passes through the left side of the cover plate 4 and is connected to the liquid storage chamber. The shape of the limit strip 8 matches the shape of the limit groove 10. The cover plate 4 and the spray plate main body 2 are commonly threadedly connected with a first threaded rod 5. The support frame 1 and the spray plate main body 2 are commonly threadedly connected with a second threaded rod 7. The left side of the cover plate 4 abuts against the right side of the spray plate main body 2. The left side of the cover plate 4 abuts against the right side of the diverter block 9. The shape of the side of the spray plate main body 2 matches the shape of the inner wall of the support frame 1.

[0025] In the first embodiment, a limiting groove 10 is provided on the lower end surface of the diverter block 9, and the side surface of the limiting strip 8 is slidably connected to the inner wall of the limiting groove 10;

[0026] Specifically, during installation, the staff can insert the diverter block 9 into the limiting strip 8 through the limiting groove 10, which can prevent the diverter block 9 from moving during operation and improve the stability of the diverter block 9 in the support frame 1.

[0029] Working principle:

[0030] After the work is completed, the staff can install the spray plate body 2 into the support frame 1, and limit the spray plate body 2 by tightening the second threaded rod 7. At this time, a plurality of spinnerets 3 are formed between the two spray plate bodies 2. Then, the staff can select the corresponding diverter block 9 as needed, install the diverter block 9 on the limiting bar 8 through the limiting groove 10, and tighten the cover plate 4 to the side wall of the support frame 1 through the first threaded rod 5. The cover plate 4 can limit the spray plate body 2 and the diverter block 9. At the same time, the liquid storage chamber can also be sealed. The staff connects the external liquid injection equipment with the connecting valve 6. To extrude two types of spinning melts, only the connecting valves 6 on both sides need to be used. To extrude three types of spinning melts, all the connecting valves 6 need to be used. The spinning melt can be injected into the liquid storage chamber. After the multiple spinning melts are mixed in the liquid storage chamber, they can be extruded into silk through the spinneret holes 3. After the work is completed, the staff can also remove the spray plate body 2 and the diverter block 9 for cleaning. At this point, the entire work process is completed.
