Description

Technical Field

[0001] This utility model relates to the field of nozzle technology for air-jet looms, and in particular to a nozzle for air-jet looms that is easy to disassemble and assemble. Background Technology

[0002] In the field of textile machinery, air-jet looms, as an important representative of high-speed shuttleless looms, have their operating efficiency and fabric quality closely related to the cleanliness of their air supply system. Air-jet looms introduce the weft yarn into the weave through a high-pressure airflow, thus requiring a high level of airflow cleanliness from the nozzle assembly. If the gas contains particulate impurities, it will not only affect weaving precision but may also cause nozzle blockage, wear, or even damage to equipment components, reducing production efficiency and equipment lifespan.

[0003] Currently, conventional nozzle structures mostly employ a single filter or a simple filtration method, which makes it difficult to effectively intercept impurities of different particle sizes, resulting in low filtration efficiency. In practical applications, airflow often contains particles of various sizes, and a single filter cannot meet the requirements of graded filtration, easily causing localized clogging of the filter, increased pressure drop, and consequently affecting airflow stability and loom operating efficiency.

[0004] Therefore, this application provides a nozzle for an air-jet loom that is easy to disassemble and reassemble to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the above-mentioned background technology by proposing a nozzle for an air-jet loom that is easy to assemble and disassemble.

A collection chamber one is formed between the filter screen one and the filter screen two. A secondary core ring is threadedly connected to the outer wall of the main core ring. A filter screen three is arranged on the secondary core ring. A collection chamber two is opened on the main core ring between the filter screen two and the filter screen three.

[0009] Preferably, the end of the main core ring away from the sub-core ring has an internal hexagonal groove for loading and unloading the main core ring.

[0010] Preferably, a trapezoidal guide plate is fixedly connected to one outer edge of the filter screen, and an internal hexagonal block is fixedly connected to the end of the trapezoidal guide plate away from the filter screen, the internal hexagonal block being in contact with the inner wall of the internal hexagonal groove.

[0011] Preferably, a baffle is fixedly connected to the outer edge of the second filter screen, and the outer wall of the baffle is fixedly connected to the outer edge of the second collection chamber. A baffle is fixedly connected to the outer edge of the third filter screen, and the baffle is fixedly connected to the inner edge of the second collection chamber.

[0012] Preferably, the first filter screen, the second filter screen, and the third filter screen are arranged in a conical shape, and the cross-sectional dimensions of the first filter screen, the second filter screen, and the third filter screen decrease sequentially.

[0013] Preferably, the pore size of the filter screens 1, 2, and 3 decreases sequentially.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The present invention provides a nozzle for a jet loom that is easy to assemble and disassemble. The nozzle 1 is threadedly connected to the jet loom. One end of the nozzle 1 body has an external thread structure for a detachable threaded connection to the mounting interface on the jet loom. A core ring 2 is threadedly connected to the inner wall of the nozzle 1. The core ring 2 is a hollow cylindrical structure with its axis aligned with the nozzle 1 body to ensure smooth airflow. A filter screen 6 and a filter screen 8 are sequentially arranged on the inner wall of the core ring 2 along the jet direction of the nozzle 1. A semi-enclosed collection chamber 9 is formed between the filter screens 6 and 8 to allow impurities to pass through, intercepting and storing larger particles carried in the gas entering from the outside. The main core ring 2 has an external thread structure on its outer wall, which allows for a detachable threaded connection with the secondary core ring 10. The secondary core ring 10 is equipped with a filter screen 3 12, which is mainly used for fine filtration of the gas after the first two layers of filtration to remove finer impurity particles. The main core ring 2 has a collection chamber 2 13 located between the filter screen 2 8 and the filter screen 3 12. The collection chamber 2 13 is isolated from the collection chamber 1 9 and is used to collect impurities of different particle sizes, realizing the functions of graded filtration and centralized cleaning, which helps to improve maintenance efficiency and extend the service life of the nozzle 1.

[0030] In this embodiment, as Figures 2-6 As shown; the main core ring 2 is provided with an internal hexagonal groove 3 at the end away from the sub-core ring 10 for loading and unloading the main core ring 2. In order to achieve quick disassembly, assembly and cleaning of the overall structure, the main core ring 2 is provided with an internal hexagonal groove 3 for rotational disassembly with the help of special tools.

[0031] In this embodiment, as Figures 3-4 As shown; a trapezoidal guide plate 4 is fixedly connected to the outer edge of filter screen 6, and an internal hexagon block 5 is fixedly connected to the end of the trapezoidal guide plate 4 away from filter screen 6. The internal hexagon block 5 and the internal hexagon slot 3 are in an interference fit.

[0032] The inner diameter of the trapezoidal guide plate 4 is smaller than the flow diameter of the filter screen 6, forming a guide structure with a certain taper. This structure can be used in conjunction with an expansion clamp tool. When the clamp is inserted into the trapezoidal guide plate 4, the clamp will elastically expand as it goes deeper and eventually fit tightly against the inner wall of the trapezoidal guide plate 4. By applying an axial tensile force to the outside, the trapezoidal guide plate 4 and the internal hexagon block 5 can be pulled out from the main core ring 2, thereby realizing the quick disassembly and replacement of the filter screen 6.

[0033] In this embodiment, as Figures 3-5 As shown; a baffle 7 is fixedly connected to the outer edge of filter screen 2 8, and the outer wall of baffle 7 is fixedly connected to the outer edge of collection chamber 2 13; a baffle 11 is fixedly connected to the outer edge of filter screen 3 12, and baffle 11 is fixedly connected to the inner edge of collection chamber 2 13.

[0034] Baffle 1 7 and Baffle 2 11 not only provide support and positioning, but also enhance the overall pressure resistance of the filter assembly and the sealing of the airflow channel; Collection chamber 2 13 serves as an intermediate impurity collection space, which can effectively intercept and store impurity particles in the area between filter screen 2 8 and filter screen 3 12, making it convenient for centralized cleaning later.

[0035] In this embodiment, as Figures 4-5 As shown; filter screen 1 6, filter screen 2 8 and filter screen 3 12 are arranged in a conical shape, and the cross-sectional dimensions of filter screen 1 6, filter screen 2 8 and the filter screen decrease sequentially.

[0036] The cone shape means that its shape is a truncated cone, and the axis of each filter screen coincides with the central axis of nozzle 1, so as to ensure that the filter pores are evenly distributed and decrease in size when the airflow passes through.

[0037] The conical structure combined with the progressively smaller filter holes not only improves filtration efficiency but also effectively avoids localized clogging, extending the filter's lifespan. Furthermore, as the filter size decreases, the airflow channel area gradually narrows, helping to increase airflow velocity and enhance the spray effect. Simultaneously, this tiered filtration structure is well-matched with the two collection chambers 9 and 13 inside the nozzle 1, which are used to collect impurity particles of different sizes, facilitating subsequent unified cleaning and maintenance.

[0038] The inner walls of collecting chamber 1 (9) and collecting chamber 2 (13) are made of magnetic material.

[0039] As the airflow passes through nozzle 1, impurities such as metal debris and metal particles mixed in with fibers are adsorbed and retained on the inner wall of the corresponding collection chamber after being filtered through the filter screen in stages. This effectively prevents them from continuing to enter the air-jet loom and causing wear, blockage or malfunction.

[0040] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
