Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to an auxiliary nozzle for an air-jet loom. Background Technology

[0002] Since the advent of air-jet loom auxiliary nozzles with air-jet weft insertion technology, they have always been a core component. Their development has progressed from the early simple round hole structure to the high-efficiency and energy-saving irregular hole design. The materials have also evolved from ordinary metals to wear-resistant ceramics and special alloys. As the relay engine of the loom weft insertion system, it continuously pulls and stabilizes the weft yarn through the shed by ejecting high-speed airflow sequentially along the reed width. It is widely used in high-speed, wide-width modern weaving scenarios from ordinary fabrics to industrial textiles, and is a key basic component for achieving high-efficiency and high-quality production.

[0003] Application No. 202420422595.9 discloses an auxiliary nozzle for an air-jet loom, including a nozzle seat. The nozzle seat contains a nozzle body mounted via a fixing assembly. A limiting assembly is installed on the right side of the nozzle seat. This utility model relates to the field of air-jet loom technology. The auxiliary nozzle for this air-jet loom uses a movable nozzle body to drive a hexagonal block, a limiting ring, and a connecting pipe into the inner wall of a through-hole. Rotating the hexagonal block causes the external and internal threads on the connecting pipe to engage, allowing the limiting ring to enter the inner wall of the placement opening. The protective plug can then be removed from the nozzle body. This design makes the installation of the nozzle simple and convenient, maintaining stability during long-term operation and preventing shaking.

[0004] While the aforementioned document simplifies the installation and operation of the nozzle and ensures its stability during long-term operation, preventing shaking, it has the following drawback: the nozzle orifice angle of the auxiliary nozzle for air-jet looms is fixed during manufacturing and cannot be adjusted during use. Therefore, an auxiliary nozzle for air-jet looms has been developed. Utility Model Content

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0019] Reference Figures 1-5 This is an embodiment of the present invention, which provides an auxiliary nozzle for an air-jet loom, comprising: The nozzle seat 101, the shaft 102 rotatably connected to the inner wall of the nozzle seat 101, the adjustment assembly 103 fixedly installed at the end of the shaft 102, and the jet assembly 104 threadedly connected to the inner wall of the adjustment assembly 103; The adjustment assembly 103 includes a mounting base 103a fixedly mounted on the end of the shaft 102, a limiting ring 103b slidably connected to the surface of the mounting base 103a, a collar 103c slidably connected to the inner wall of the nozzle seat 101, and a pin 103d inserted into the inner wall of the collar 103c.

[0020] Pulling the pull plate 103e causes the pin 103d to slide outward along the groove hole between the collar 103c and the nozzle seat 101, compressing the spring 103f and causing the end of the pin to disengage from the limiting hole on the side wall of the mounting base 103a, thus unlocking the angle adjustment function. Then, rotating the shaft 102 causes the mounting base 103a and the jet assembly 104 to rotate synchronously, adjusting the jet direction of the nozzle.

[0021] Specifically, the adjustment assembly 103 also includes a pull plate 103e fixedly installed at the end of the pin 103d, and a spring 103f sleeved on the surface of the pin 103d.

[0022] Furthermore, the side wall of the mounting base 103a is provided with a limiting hole adapted to the pin 103d, the pin 103d is inserted into the side wall of the mounting base 103a, the limiting ring 103b is fixedly installed on the inner wall of the nozzle seat 101, and the side wall of the nozzle seat 101 is provided with a sliding groove hole adapted to the collar 103c.

[0023] Specifically, when the target angle of the weft yarn flight path is aligned, the pull plate 103e is released, the spring 103f returns to its original deformation, pushes the pin 103d to slide inward, and inserts it into the corresponding limiting hole of the mounting base 103a to complete the angle locking and prevent the angle from shifting due to vibration during the weaving process.

[0024] Preferably, the jet assembly 104 includes a nozzle body 104a that is threadedly connected to the inner wall of the mounting base 103a, a hexagonal block 104b fitted on the surface of the nozzle body 104a, a connection port 104c communicating with the bottom of the nozzle body 104a, a round nozzle 104d communicating with the end of the nozzle body 104a, and a rectangular nozzle 104e that is threadedly connected to the end of the round nozzle 104d, wherein the inner wall of the rectangular nozzle 104e is rectangular.

[0025] It should be noted that if concentrated airflow is needed to guide fine weft yarns, round nozzle 104d can be used directly. If wide airflow is needed to support coarse weft yarns or wide fabrics, rectangular nozzle 104e can be installed on the end of round nozzle 104d by thread. The nozzle body 104a can be rotated by hexagonal block 104b to make it threadedly fastened to mounting base 103a to ensure a tight seal without air leakage.

[0026] In use, pull the pull plate 103e, causing the pin 103d to slide outward along the groove hole between the collar 103c and the nozzle seat 101, compressing the spring 103f, so that the end of the pin disengages from the limiting hole on the side wall of the mounting base 103a, unlocking the angle adjustment function. Then, rotate the shaft 102, causing the mounting base 103a and the jet assembly 104 to rotate synchronously, adjusting the jet direction of the nozzle until it is aligned with the target angle of the weft yarn flight path. Release the pull plate 103e, the spring 103f returns to its original deformation, and pushes the pin... Pin 103d slides inward and inserts into the corresponding limiting hole of mounting base 103a to lock the angle and prevent angle deviation caused by vibration during weaving. If concentrated airflow is needed to guide fine weft yarn, round nozzle 104d can be used directly. If wide airflow is needed to support coarse weft yarn or wide fabric, rectangular nozzle 104e can be installed on the end of round nozzle 104d by thread. The nozzle body 104a is rotated by hexagonal block 104b to make it threadedly fastened to mounting base 103a to ensure a tight seal without air leakage.

[0027] In summary, by adjusting the settings of component 103, the spray angle can be adjusted and reliably locked, which can flexibly adapt to the weaving needs of different weave widths and different weft yarn paths. Equipped with two types of detachable nozzles, round and rectangular, the airflow pattern can be switched according to the weft yarn characteristics and fabric density. The device is easy and efficient to operate, effectively solving the problem of the limited adaptability of traditional fixed-angle nozzles and ensuring the stability of weft yarns across the entire weave width.
