Description

Technical Field

[0001] This utility model belongs to the field of water jet looms, and in particular relates to a water jet loom for Oxford spinning production and its nozzle. Background Technology

[0002] Oxford cloth, also known as Oxford textile, is a versatile fabric with a wide range of uses. The main varieties on the market are: checkered, full stretch, nylon, and jacquard. It originated in England and is a traditional combed cotton fabric named after Oxford University. A loom is a machine used to interweave two or more sets of yarns at right angles to form a fabric. There are looms and brocade looms. Oxford cloth requires the use of water jet looms for processing. A water-jet loom is a shuttleless loom that uses the frictional traction force generated by a jet of clean water to guide the weft yarn through the shed. It is generally used for weaving synthetic fiber fabrics, such as glass fiber and hydrophobic synthetic filaments. Water-jet weft insertion exerts a greater frictional traction force on the weft yarn than air-jet weft insertion, with less diffusion, effectively overcoming static electricity during weaving. The energy consumed by jetting the weft yarn is less, resulting in lower noise, making it a widely used type of shuttleless loom.

[0003] According to publicly available patent CN222226741U, a water jet loom nozzle structure includes a nozzle body and a nozzle head threadedly connected to the end of the nozzle body. The nozzle body includes an integrally formed and interconnected yarn guide tube and a water inlet tube. One end of the yarn guide tube is fixedly connected to a yarn guide, and the other end is fixedly connected to the nozzle head. The inner wall of the yarn guide tube has a first internal thread near the yarn guide and a second internal thread near the nozzle head. The nozzle head is hourglass-shaped, with a waist section in the middle and a cavity with openings at both ends inside. A section is formed on the outer wall of the nozzle head near the yarn guide tube. With a second external thread, the nozzle of this invention, based on the original threaded connection, is further fixed by a fixing strip. When the nozzle rotates out, the fixing strip will prevent the nozzle from moving outward. However, existing nozzles rely on a water injection channel arranged on one side to introduce high-pressure jet into the hollow cavity inside the nozzle body, and then spray it outward through the jet outlet opened at the front end of the body. When the high-speed jet comes into contact with and collides with the outside air, the air environment will have a resistance attenuation effect on the jet. During the continuous jet spraying process, the jet shape will change, such as dispersion and atomization, which will affect the quality of the yarn guide. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a water jet loom for Oxford spinning production. The annular pipe and annularly arranged water inlet holes ensure more uniform water intake, while the inclined air inlet holes enhance jet kinetic energy and reduce air resistance attenuation of the jet. The guide ring and baffles optimize the water flow pattern, reduce jet dispersion and atomization, and improve yarn guiding quality.

[0005] In view of this, the present invention provides a water-jet loom for Oxford cloth production, comprising: A tube body, one end of which is threadedly connected to a weft yarn feed nozzle; The outer circumferential groove of the tube body is provided with several water inlet holes, all of which are connected to the inner cavity of the tube body. An annular tube is fixedly connected to the outer circumferential groove, and one end of the annular tube is connected to a water inlet pipe. Several air inlets are provided on one side of the groove on the outer periphery of the tube, and the air inlets are all inclined toward the weft yarn injection direction. A guide ring is fixedly connected to the inner cavity of the tube, and multiple baffles are fixedly connected at equal intervals to the inner cavity of the guide ring.

[0006] In this technical solution, the water intake is more uniform through the annular pipe and the annular water inlet holes. The inclined air inlet holes can enhance the jet kinetic energy and reduce the attenuation of the jet by air resistance. The guide ring and baffle can optimize the water flow pattern, reduce jet dispersion and atomization, and improve the yarn guiding quality.

[0007] Furthermore, several of the water inlet holes are distributed in a circular, equidistant pattern on the outside of the pipe body.

[0008] In this technical solution, the water inlet holes are distributed in a circular and equidistant manner, which allows the water to enter the inner cavity of the tube evenly, avoids local water flow turbulence, reduces the instability of the jet shape, and facilitates yarn guidance.

[0009] Furthermore, several of the air inlets are distributed in a circular, equidistant pattern on the outer side of the tube.

[0010] In this technical solution, the air inlets are distributed in a circular and equidistant manner, allowing the airflow to mix evenly with the water flow, stabilizing the jet structure, reducing jet dispersion caused by uneven airflow, and ensuring the yarn guiding effect.

[0011] Furthermore, filters are fixedly connected to the outer sides of several of the air inlets.

[0012] In this technical solution, the filter screen on the outside of the air inlet can prevent impurities from entering, avoid clogging the air hole and affecting the airflow supply, ensure jet stability, and reduce yarn guiding quality problems.

[0013] Furthermore, a rubber sealing ring is provided between the annular tube and the outer circumferential groove of the tube body, and the rubber sealing ring is elastic.

[0014] In this technical solution, the rubber sealing ring enhances the sealing performance between the annular tube and the tube body, preventing water leakage that could lead to unstable water pressure, ensuring stable jet intensity, and reducing the impact of jet shape changes on the yarn guide.

[0015] Furthermore, a nut is fixedly connected to the outer side of the tube near the weft yarn feed nozzle.

[0016] In this technical solution, the nozzle is easily installed and fixed by a nut at one end of the tube.

[0017] Furthermore, the guide ring is placed between the water inlet and the air inlet, and is sleeved on the weft yarn feed nozzle, and the multiple baffles do not contact the weft yarn feed nozzle.

[0018] In this technical solution, the guide ring is located between the water inlet and the air inlet, which can guide the water flow and air flow to mix fully without interfering with the operation of the weft yarn feed nozzle.

[0019] Furthermore, the inner walls of both the water outlet end of the tube and the feed end of the weft yarn feed nozzle are rounded.

[0020] In this technical solution, the inner walls of the water outlet and feed inlet are rounded to reduce the resistance of water flow and air flow, avoid turbulence, maintain the stability of the jet shape, and reduce the impact of atomization on the yarn guide.

[0021] A water-jet loom employs a water-jet loom nozzle for Oxford spinning production. The water-jet loom nozzle for Oxford spinning production is fixed to the loom frame or reed base via a flange, fastening bolts, or a special bracket. Its spray nozzle is aligned with the warp opening channel, and the water inlet pipe is connected to the high-pressure water system of the loom via a pipe joint.

[0022] The beneficial effects of this utility model are: This invention uses an annular tube and an annularly arranged water inlet to make the water intake more uniform. Combined with the inclined air inlet, it can enhance the jet kinetic energy and reduce the attenuation of the jet by air resistance. The guide ring and baffle can optimize the water flow pattern, reduce jet dispersion and atomization, and improve the yarn guiding quality. Attached Figure Description

[0030] Example 1: like Figure 1-3 As shown, this utility model provides a water-jet loom for Oxford spinning production, comprising: a tube body 1, one end of which is threadedly connected to a weft yarn feed nozzle 4; a plurality of water inlet holes 2 are provided in the outer peripheral groove of the tube body 1, all of which are connected to the inner cavity of the tube body 1, and an annular tube 8 is fixedly connected in the outer peripheral groove, one end of which is connected to a water inlet pipe 9; a plurality of air inlet holes 5 are provided on one side of the outer peripheral groove of the tube body 1, all of which are inclined toward the weft yarn spraying direction; a guide ring 11 is fixedly connected to the inner cavity of the tube body 1, and a plurality of baffles 6 are fixedly connected at equal intervals in the inner cavity of the guide ring 11.

[0031] During operation, the water inlet pipe 9 delivers high-pressure water to the outer groove of the pipe body 1 through the annular pipe 8, and then the water enters the inner cavity evenly from all sides of the pipe body 1 through multiple water inlet holes 2, avoiding water flow deviation caused by unilateral water injection. At the same time, the air inlet hole 5 is inclined towards the direction of weft yarn injection, so that the gas mixes with the water flow along the jet direction, forming a gas-liquid mixed jet to enhance kinetic energy and reduce the resistance attenuation when the jet collides with the outside air. In addition, the guide ring 11 and baffle 6 in the inner cavity of the pipe body 1 guide the water flow to form an orderly flow field, suppress the generation of turbulence, further stabilize the jet shape, reduce dispersion and atomization, and ensure the quality of yarn guidance.

[0032] Several of the water inlet holes 2 are distributed in a circular pattern at equal intervals on the outside of the pipe body 1.

[0033] The water inlet holes 2 are distributed in a circular pattern at equal intervals, allowing high-pressure water to enter the inner cavity simultaneously from multiple points around the pipe body 1. The water flow forms a symmetrical pressure field inside the pipe body 1, avoiding flow field disturbances caused by local water flow velocity differences. As a result, the uniform water flow can form a stable columnar flow inside the pipe body 1, reducing the swaying or dispersion of the jet caused by uneven water flow, and ensuring the stable traction of the jet on the weft yarn.

[0034] Several of the air inlets 5 are distributed in a circular pattern at equal intervals on the outside of the tube body 1.

[0035] The air inlets 5 are distributed in a circular and equidistant manner, allowing the gas to be evenly mixed with the water flow from all sides of the pipe body 1. The airflow from each air inlet 5 forms a symmetrical gas-liquid mixing zone in the inner cavity of the pipe body 1. This uniform gas distribution can balance the kinetic energy of each part of the jet, avoid jet breakage and atomization caused by excessive or insufficient local gas volume, and maintain the integrity of the jet structure.

[0036] A filter screen 7 is fixedly connected to the outer side of each of the aforementioned air inlets 5.

[0037] The filter screen 7 outside the air inlet 5 intercepts impurities when the airflow enters, preventing impurities from clogging the air hole and causing local airflow interruption. The continuous and smooth airflow supply can ensure a stable gas-liquid mixing ratio, avoid sudden changes in jet shape caused by airflow fluctuations, and ensure the continuous and effective traction of the jet on the weft yarn.

[0038] A rubber sealing ring 10 is provided between the annular tube 8 and the outer circumferential groove of the tube body 1, and the rubber sealing ring 10 is elastic.

[0039] The rubber sealing ring 10 forms an elastic seal between the annular pipe 8 and the groove of the pipe body 1, preventing high-pressure water from leaking from the gap. This stabilizes the water pressure, making the water flow pressure output from the inlet hole 2 uniform, avoiding local pressure drop caused by water leakage, ensuring stable jet intensity, and reducing jet dispersion caused by pressure fluctuations.

[0040] A nut 3 is fixedly connected to the outer side of the tube body 1 near the weft yarn feed nozzle 4.

[0041] The nut 3 at one end of the tube 1 allows the operator to easily rotate the tube 1 with a wrench and screw the tube 1 onto the outside of the weft yarn feed nozzle 4.

[0042] The guide ring 11 is placed between the water inlet 2 and the air inlet 5, and is sleeved on the weft yarn feed nozzle 4, and the multiple baffles 6 do not contact the weft yarn feed nozzle 4.

[0043] The guide ring 11 is located between the water inlet 2 and the air inlet 5. It can guide the water flowing in from the water inlet 2 and the gas injected into the air inlet 5 to mix fully in the ring, forming a uniform gas-liquid two-phase flow. It is sleeved outside the weft yarn feed nozzle 4 and the baffle 6 does not contact the feed nozzle. It can regulate the flow field through the baffle 6 without interfering with the weft yarn delivery, so that the jet tightly wraps the weft yarn and reduces the failure of the guide yarn caused by the separation of the jet and the weft yarn.

[0044] The inner walls of the water outlet end of the tube body 1 and the feed end of the weft yarn feed nozzle 4 are both rounded.

[0045] By setting the inner wall rounded corners of the water outlet end of tube 1 and the feed end of weft yarn nozzle 4, the local resistance when the fluid flows through can be reduced, avoiding turbulence caused by right angle structure. In turn, the smooth flow channel keeps the water flow and air flow in a laminar state, reduces the energy loss inside the jet caused by turbulence, maintains the stability of the jet shape, and reduces the impact of atomization on the yarn guiding quality.

[0046] A water-jet loom, wherein the nozzle of the water-jet loom for Oxford spinning production is fixed to the loom frame or reed seat by a flange, fastening bolts or a special bracket, the spray nozzle is aligned with the warp opening channel, and the water inlet pipe 9 is connected to the high-pressure water system of the loom through a pipe joint.

[0047] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
