The utility model provides a series of structures to facilitate the device to change the aperture of the yarn outlet and to facilitate installation and disassembly.

[0004] The existing technology has the following deficiencies in use: 1. There is no sealing treatment between the plates. During long-term use, the friction between the plates will cause gaps, and the pressure during the spinning process will cause the liquid to flow into the gaps; 2. Each replacement will cause the upper plate to loosen and fall off, which not only increases the wear between the plates, but also makes the operation more troublesome; 3. During the replacement process, it is difficult to align and position the troughs, which affects the spray flow rate from the top. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a spinneret for producing degradable nylon yarns, so as to solve the problems of wear, cumbersome operation and difficult positioning of the spinneret during use.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a spinneret for the production of degradable nylon yarn, whose structure includes a spinneret body, a clamp, a mounting rod, and a spray hole. The spinneret body is located between the clamps, and the spinneret body is divided into four spinneret units from top to bottom. Each spinneret unit is provided with a number of spray holes. Limiting grooves and sealing rubber rings are distributed on the lower surfaces of adjacent spinneret units. The sealing rubber rings are located inside the limiting grooves. An annular ring is provided on the lower surfaces of adjacent spinneret units, and the inside of the annular ring is the spray hole.

[0007] Furthermore, the diameter of the spray hole of the spray plate unit decreases from top to bottom, and the diameter of the spray hole on the upper surface of each spray plate unit is larger than the diameter of the spray hole on the lower surface.

[0008] Furthermore, a support pad is provided on the inner upper surface of the clamp.

[0009] Furthermore, an extrusion rod is provided below the clamp.

[0010] Furthermore, sliding grooves are provided on the sides of the spray plate units on the spray plate body.

[0011] Furthermore, four spring rods are provided on the side of the clamp, and the spring rods form a matching relationship with the limiting grooves on the spray plate unit.

[0012] Furthermore, mounting rods are provided on both sides of the clamp.

[0013] Beneficial Effects

[0014] The utility model discloses a spinneret for producing degradable nylon yarn. The spinneret body is fixed by a clamp, and the size of the aperture is controlled by increasing or decreasing the number of the spinneret units. During the adjustment process, the spinneret unit is loosened by first loosening the extrusion rod, and the spinneret unit at this time will not fall. The spring rod is pulled outward, and the spinneret unit of the lower layer is not restricted and thus falls, while the spinneret unit of the upper layer is in a suspended state under the action of the spring rod. After the increase or decrease is completed, the extrusion rod is tightened in the opposite direction. Under the action of the extrusion rod, the annular ring on the upper surface of the lower layer of the spinneret unit falls into the limiting groove on the lower surface of the upper layer of the spinneret unit. As the extrusion rod is continuously tightened, the annular ring squeezes the sealing rubber ring in the limiting groove until the spinneret units fit together, which plays the role of positioning and sealing, reduces the wear degree of the surface of the spinneret unit, and improves the service life. Moreover, under the action of the spring rod, each spinneret unit is effectively restricted during the replacement process, and will not fall as the lower layer of the spinneret unit is separated, thereby increasing the stability of use and making the operation more convenient and efficient.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] See also Figure 1-Figure 5 The utility model provides a technical solution for a spinneret for producing degradable nylon yarn, and its structure includes a spinneret body 1, a clamp 2, a mounting rod 3, and a spray hole 4. The spinneret body 1 is located between the clamps 2, and the spinneret body 1 is evenly divided into four spinneret units 5 from top to bottom. Each spinneret unit 5 is distributed with a plurality of the spray holes 4. The lower surfaces of adjacent spinneret units 5 are distributed with limiting grooves 6 and sealing rubber rings 7. The sealing rubber rings 7 are located inside the limiting grooves 6. The lower surfaces of adjacent spinneret units 5 are provided with annular rings 8, and the inside of the annular rings 8 is the spray hole 4.

[0024] The diameter of the spray holes 4 of the spray plate unit 5 decreases from top to bottom, and the diameter of the spray holes 4 on the upper surface of each spray plate unit 5 is larger than the diameter of the spray holes 4 on the lower surface.

[0025] A support pad 9 is provided on the inner upper surface of the clamp 2 .

[0026] A pressing rod 10 is provided below the clamp 2 .

[0027] The sides of the spray plate units 5 on the spray plate body 1 are all provided with sliding grooves.

[0028] Four spring rods 11 are disposed on the side of the clamp 2 , and the spring rods 11 form a matching relationship with the limiting grooves on the spray plate unit 5 .

[0029] The mounting rods 3 are provided on both sides of the clamp 2 .

[0030] Principle of use: The spray plate body 1 is fixed by the clamp 2, and the size of the aperture is controlled by increasing or decreasing the number of the spray plate units 5. During the adjustment process, the spray plate unit 5 is loosened by loosening the extrusion rod 10. At this time, the spray plate unit 5 will not fall off. The spring rod 11 is pulled outward, and the spray plate unit 5 of the lower layer is not restricted and falls off, while the spray plate unit 5 of the upper layer is in a suspended state under the action of the spring rod 11. After the increase or decrease is completed, the extrusion rod 10 is tightened in the opposite direction. Under the action of the extrusion rod 10, the annular ring 8 on the upper surface of the lower spray plate unit 5 falls into the limiting groove 6 on the lower surface of the upper spray plate unit 5. As the extrusion rod 10 is continuously tightened, the annular ring 8 squeezes the sealing rubber ring 7 in the limiting groove 6 until the spray plate units 5 fit together, which plays a role of positioning and sealing, reduces the wear on the surface of the spray plate unit 5, and increases the service life. Moreover, under the action of the spring rod 11, each spray plate unit 5 is effectively restricted during the replacement process and will not fall off as the lower spray plate unit 5 is detached, thereby increasing the stability of use and making the operation more convenient and efficient.
