Description

Technical Field

[0001] The utility model belongs to the technical field of spinnerets, and particularly relates to a spinneret with detachable nozzles. Background Art

[0002] The spinneret is equipped with a spinneret head. The thimble-shaped metal nozzle for artificial fiber spinning has many small holes, and the spinning solution is extruded from the holes to form filaments. The raw material is melted or dissolved into a viscous solution by chemical methods, and after flowing out of the spinneret, it forms a filament, which is solidified by condensation, evaporation or cooling. As an important equipment for manufacturing synthetic fibers, the spinneret is an indispensable precision component in the spinning machine.

[0003] In the production process of existing chemical fiber filaments, the raw material in a high-temperature and molten state is poured into the spinneret, and the raw material is extruded from the spinneret holes. Since the chemical fiber is solidified by side blowing or ring blowing cooling immediately after being ejected from the spinneret holes, and at the same time, due to the usually very fine diameter of the spinneret holes, the sudden change of the raw material from a high-temperature molten state to a low-temperature solidified state easily causes some raw materials to solidify and accumulate at the outlet of the spinneret holes. Therefore, there are often problems that individual holes in the spinneret holes are blocked and it is not convenient to clean, thus affecting the production progress. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a spinneret with detachable nozzles to solve the technical problem that the spinneret holes are often blocked and it is not convenient to clean.

[0005] To solve the above technical problems, the utility model provides a spinneret with detachable nozzles, which includes a plate. The plate includes two ends, an inlet surface and an outlet surface. A plurality of cavities are provided in the plate, and a hole tube is provided in each of the plurality of cavities. The hole tube includes two ends, an inlet hole and an outlet hole. A convex ring is connected to the hole tube at the outlet hole, and the convex ring is threadedly connected to the plate.

[0006] Preferably, the inlet hole and the inlet surface are at the same end, and the outlet hole and the outlet surface are at the same end.

[0007] Preferably, the hole tube is threadedly connected to the convex ring.

[0008] Preferably, the hole tubes are arranged in an arc segment and evenly distributed on the plate.

[0009] Preferably, the cross-section of the hole tube is trapezoidal.

[0010] Preferably, the diameter of the inlet hole is larger than the diameter of the outlet hole.

[0011] Preferably, a positioning through hole is provided at the center of the plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. During the operation of the spinneret plate, individual hole tubes are often blocked, and the overall cleaning method is rather troublesome. In this device, by unscrewing the corresponding convex ring, the hole tube can be directly taken out from the cavity and then cleaned by rinsing with clean water. In addition, long-term operation of the spinneret plate may even cause damage to the holes inside, and in severe cases, the entire spinneret plate needs to be replaced. However, by adding hole tubes inside the holes, if the hole tubes are damaged, they can be directly replaced.

[0014] 2. The hole tubes are arranged in an arc segment and evenly distributed on the plate. High-temperature raw materials can be contacted at each position, and the temperature can be quickly transferred to each position of the plate, ensuring the same high temperature at each position of the plate and avoiding problems such as blockage of some through holes caused by uneven temperature.

[0015] Other features and advantages of the utility model will be described in the following description, and in part, will be obvious from the description, or can be understood by implementing the utility model.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1-3 , a spinneret with detachable nozzles, comprising a plate 1. The plate 1 is cylindrical, and the plate 1 includes two ends, namely a feed surface 11 and a wire outlet surface 12. The feed surface 11 and the wire outlet surface 12 are circular planes. A plurality of cavities 2 are provided inside the plate 1. The cavities 2 are frustum-shaped columns. A hole tube 3 is provided inside each of the plurality of cavities 2. The hole tube 3 is frustum-shaped columnar and matches the cavity 2. The hole tube 3 includes two ends, namely an inlet hole 31 and an outlet hole 32. A convex ring 4 is connected to the hole tube 3 at the outlet hole 32. The convex ring 4 is circular, and the inner circle of the convex ring 4 has the same size as the outlet hole 32 of the hole tube 3. The convex ring 4 is threadedly connected to the plate 1. External threads are provided on the convex ring 4, and internal threads are provided on the plate 1.

[0025] The inlet hole 31 and the feed surface 11 are at the same end, and the outlet hole 32 and the wire outlet surface 12 are at the same end, which is convenient for unified work planning.

[0026] The hole tube 3 is threadedly connected to the convex ring 4. The threaded connection method is a detachable fixed connection widely used in daily life, which has the advantages of simple structure, reliable connection, and convenient installation and disassembly. As Figure 2 shown, the hole tubes 3 are arranged in an arc segment and evenly distributed on the plate 1, so that each position inside the plate 1 can contact the high-temperature raw material, and the temperature can be transmitted to each position of the plate 1 as soon as possible, ensuring the same high temperature at each position of the entire plate 1 and avoiding problems such as blockage of some hole tubes 3 caused by uneven temperature.

[0027] As Figure 3 shown, the diameter of the inlet hole 31 is larger than the diameter of the outlet hole 32. The cross-section of the hole tube 3 is trapezoidal. Both the tube hole 3 and the cavity 2 are frustum-shaped columns and are mutually adapted, which is convenient for the hole tube 3 to be installed and removed from the feed surface 11 inside the cavity 2, and the wire outlet surface 12 is fixed by threaded connection with the convex ring 4, so that there is a good installation and fixation effect between the cavity 2 and the hole tube 3, and it is also convenient for spinning.

[0028] A positioning through hole 5 is provided at the center of the plate 1. The spinning equipment connected to the plate 1 needs to be provided with a positioning pin matching the positioning through hole 5. A clearance fit connection is adopted between the positioning through hole 5 and the positioning pin, which is convenient for installation and disassembly.

[0029] The material of the orifice tube 3 is a high-temperature resistant material, which ensures that the device can work for a long time and extends its service life.

[0030] Working principle: When the orifice tube 3 is blocked or damaged, the staff unscrews the corresponding convex ring 4 from the plate 1, and the fixed connection of the orifice tube 3 with it is also cancelled. Then, the orifice tube is taken out of the cavity 2 from the feeding surface 11, and the orifice tube 3 is washed and cleaned with water. If it is damaged, a new orifice tube 3 needs to be selected, and then it is inserted back into the cavity 2 from the feeding surface 11 in the reverse steps, and the convex ring 4 is screwed back onto the plate 1 to complete the fixation, realizing the advantage of convenient cleaning of the present utility model.
