Description

Technical Field

[0001] This utility model relates to the technical field of weft insertion devices for air-jet looms, and in particular to a non-circular oscillating four-color main nozzle. Background Technology

[0002] As a key piece of equipment in the modern textile industry, the weft insertion device on an air-jet loom precisely guides the weft yarn through the shed using compressed air jets, completing the weaving process. This device offers significant advantages in production speed and greatly improves labor productivity. It is highly efficient for producing plain and textured fabrics, as well as coarse and fine high-density fabrics, greatly meeting the market's demand for diverse fabrics and powerfully promoting the development of the textile industry.

[0003] However, in actual production, when dealing with yarns of different thicknesses, the fixed structure of the main nozzle makes it impossible to flexibly adjust the nozzle angle and weft insertion flow rate. This can lead to poor weft insertion results when handling yarns of varying thicknesses. Either the thicker yarns cannot be effectively pulled, or the pulling force on the thinner yarns is too great, resulting in waste. It is difficult to achieve the best weft insertion effect while reducing energy consumption, thus limiting further improvements in production efficiency and product quality. Utility Model Content

[0004] The purpose of this invention is to provide an irregularly shaped, oscillating four-color main nozzle, aiming to solve the problem in existing technologies where, in actual production, the fixed structure of the main nozzle prevents flexible adjustment of the nozzle angle and weft insertion flow rate when dealing with yarns of different thicknesses. This leads to poor weft insertion performance when handling yarns of varying thicknesses; either thicker yarns cannot be effectively pulled, or excessive pulling force is applied to thinner yarns, resulting in waste. It is difficult to achieve optimal weft insertion while reducing energy consumption, thus limiting further improvements in production efficiency and product quality.

[0005] To achieve the above objectives, this utility model employs an irregularly shaped, oscillating, four-color main nozzle, comprising a bracket body, multiple fixing screws, and a support plate. The bracket body is equipped with a nozzle assembly. The upper end face of the bracket body has a waist-shaped hole and multiple upper mounting holes. The upper end face of the support plate has multiple lower mounting holes. The bracket body is fixedly connected to the support plate by multiple fixing screws and is located above the support plate. The multiple fixing screws are respectively located in the corresponding waist-shaped hole, the corresponding upper mounting hole, and the corresponding lower mounting hole.

[0006] The nozzle assembly includes multiple main nozzles and an aluminum sleeve. An air inlet is provided on the outer side of the aluminum sleeve, and a nozzle core is provided at one end of the aluminum sleeve. The multiple main nozzles are respectively provided at the other end of the aluminum sleeve and extend to the bracket body. The aluminum sleeve is provided on the bracket body.

[0007] The number of air intake connectors is four, and the four air intake connectors are arranged in a cross shape around the outside of the aluminum sleeve.

[0008] The number of spray cores is four, and the four spray cores are arranged in a cross shape around one end of the aluminum sleeve.

[0009] The aluminum sleeve has four communicating cavities. Each communicating cavity has a first communicating hole on one side, a second communicating hole at one end, and a third communicating hole at the other end. An accelerator is installed in one of the communicating cavities, and the accelerator is located between the corresponding first communicating hole, second communicating hole, and third communicating hole.

[0010] In this configuration, one of the air intake connectors, one of the nozzles, and one of the main nozzles are all connected to the accelerator. Each of the other air intake connectors is connected to the corresponding first connecting hole, each of the nozzles is connected to the corresponding second connecting hole, and each of the main nozzles is connected to the corresponding third connecting hole.

[0011] The support plate is provided with a positioning pin, the bracket body has a positioning hole, and the positioning pin is inserted into the positioning hole.

[0012] This utility model discloses an irregularly shaped, oscillating four-color main nozzle. The bracket body features a waist-shaped hole and multiple upper mounting holes, which, in conjunction with multiple lower mounting holes and fixing screws on the support plate, allow the bracket body to be fixed to the support plate and adjusted at small angles. This enables flexible adjustment of the nozzle angle to adapt to the traction requirements of different yarns. Simultaneously, the aluminum sleeve has four air inlet connectors, four nozzle cores, and multiple main nozzles. Combined with the four connecting cavities and accelerator design inside the aluminum sleeve, each air inlet connector, nozzle core, and main nozzle can be connected as needed, achieving precise adjustment of the weft insertion flow rate. Thus, whether using thick or thin yarns, the optimal weft insertion effect can be achieved by adjusting the nozzle angle and weft insertion flow rate, effectively traction the yarn while avoiding energy waste, significantly improving production efficiency and product quality.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] Please see Figures 1 to 6 This utility model provides an irregularly shaped swinging four-color main nozzle, including a bracket body 1, multiple fixing screws 2 and a support plate 3. The bracket body is provided with a nozzle assembly. The upper end face of the bracket body 1 has a waist-shaped hole 4 and multiple upper mounting holes 5. The upper end face of the support plate 3 has multiple lower mounting holes 6. The bracket body 1 is fixedly connected to the support plate 3 by multiple fixing screws 2 and is located above the support plate 3. The multiple fixing screws 2 are respectively located in the corresponding waist-shaped hole 4, the corresponding upper mounting hole 5 and the corresponding lower mounting hole 6.

[0023] In this embodiment, the bracket body 1 is adjusted at a small angle on the support plate 3 through the waist-shaped hole 4, so that the nozzle angle can be flexibly adjusted according to the thickness of different yarns and process requirements, which optimizes the weft insertion trajectory and spraying effect, while maintaining structural stability and solving the problem that traditional fixed nozzles are difficult to adapt to diversified production needs.

[0024] Furthermore, the nozzle assembly includes multiple main nozzles 7 and an aluminum sleeve 8. An air inlet 9 is provided on the outer side of the aluminum sleeve 8. A nozzle core 10 is provided at one end of the aluminum sleeve 8. The multiple main nozzles 7 are respectively provided at the other end of the aluminum sleeve 8 and extend to the bracket body 1. The aluminum sleeve 8 is provided on the bracket body 1.

[0025] In this embodiment, by integrating the air inlet connector 9, the nozzle core 10, and the main nozzle 7 into the same structure, the assembly process is simplified and the rigidity of the components is improved; the design of the main nozzle 7 extending to the bracket body 1 ensures that the airflow path is short and straight, reducing energy loss, while facilitating the maintenance and replacement of nozzle components.

[0026] Furthermore, there are four air intake connectors 9, which are arranged in a cross shape around the outside of the aluminum sleeve 8.

[0027] In this embodiment, the four air inlets 9 arranged in a cross shape realize multi-directional airflow input, and the air pressure and flow rate in each direction can be independently adjusted for different yarn types (such as roving or fine yarn), thereby accurately controlling the weft traction force, avoiding the problem of weft insertion failure or excessive energy consumption caused by uneven airflow, and improving the adaptability of the equipment.

[0028] Furthermore, the number of the spray cores 10 is four, and the four spray cores 10 are arranged in a cross shape around one end of the aluminum sleeve 8.

[0029] In this embodiment, the four nozzles 10 arranged in a cross shape (including two specifications: large aperture for roving and small aperture for yarn) can be replaced independently or used in combination, enabling a single device to process yarns of different thicknesses simultaneously without replacing the entire nozzle, significantly reducing production changeover costs and time. At the same time, the coupling efficiency between airflow and yarn is optimized through specification matching.

[0030] Furthermore, the aluminum sleeve 8 has four communicating cavities 11, each communicating cavity 11 has a first communicating hole 12 on one side, a second communicating hole 13 at one end of the communicating cavity 11, and a third communicating hole 14 at the other end of the communicating cavity 11. An accelerator 15 is provided in one of the communicating cavities 11, and the accelerator 15 is located between the corresponding first communicating hole 12, second communicating hole 13 and third communicating hole 14.

[0031] In this embodiment, the four independent connecting cavities 11 inside the aluminum sleeve 8 are integrated with the accelerator 15, so that the airflow can be compressed and modulated before entering the spinneret 10, and then accelerated by the accelerator 15 and precisely acted on the weft surface. This structure not only ensures the uniformity of airflow, but also reduces airflow interference and improves weft insertion stability through the modular cavity design.

[0032] Furthermore, one of the air intake connectors 9, one of the nozzles 10, and one of the main nozzles 7 are all connected to the accelerator 15, and each of the other air intake connectors 9 is connected to the corresponding first connecting hole 12, each of the nozzles 10 is connected to the corresponding second connecting hole 13, and each of the main nozzles 7 is connected to the corresponding third connecting hole 14.

[0033] In this embodiment, the airflow is split and precisely controlled through this connection method: the channel connected to the accelerator 15 is responsible for high-speed airflow output, which is suitable for roving traction; other independent channels provide low-flow airflow, which is suitable for fine yarn; this differentiated design enables a single device to meet the production needs of multiple specifications of yarn at the same time, reducing energy consumption and equipment space occupation.

[0034] Furthermore, the support plate 3 is provided with a positioning pin 16, the bracket body 1 has a positioning hole 17, and the positioning pin 16 is inserted into the positioning hole 17.

[0035] In this embodiment, the cooperation between the positioning pin 16 and the positioning hole 17 ensures the accurate reset of the bracket body 1 after angle adjustment, avoiding angle deviation caused by vibration or long-term use, thereby ensuring the long-term stability of the weft insertion angle. This design improves the reliability of equipment operation, reduces the defect rate caused by angle error, and further optimizes production efficiency.

[0036] In this invention, the support plate 3 is first securely installed in the designated position on the loom. The positioning pin 16 is precisely inserted into the positioning hole 17 on the bracket body 1 to ensure the initial angle of the bracket body 1 is accurate and to prevent displacement due to vibration during subsequent operation. Next, according to the thickness of the yarn to be processed, the relative angle between the bracket body 1 and the support plate 3 is finely adjusted through the waist-shaped hole 4 on the upper end face of the bracket body 1, so that the spray direction of the nozzle assembly is perfectly matched with the weft yarn traction path. After adjustment, the fixing screw 2 is passed through the waist-shaped hole 4, the upper mounting hole 5, and the lower mounting hole 6 to firmly lock the bracket body 1 onto the support plate 3. Subsequently, the appropriate nozzle core 10 is selected according to the yarn type (a large-diameter nozzle core 10 is used for roving, and a small-diameter nozzle core 10 is used for fine yarn) and installed onto the aluminum sleeve 8. The cross-shaped layout holes at one end are used to install the main nozzle 7 of the corresponding specification to the other end of the aluminum sleeve 8 and extend it to the bracket body 1; then, the four air inlet joints 9 are connected to the outside of the aluminum sleeve 8 in a cross shape. By independently adjusting the air pressure and flow rate of each air inlet joint 9, the airflow is split through the four connecting chambers 11 inside the aluminum sleeve 8. The channel connected to the accelerator 15 provides high-speed airflow, which is compressed and modulated by the accelerator 15 and then precisely sprayed through the corresponding nozzle core 10 and main nozzle 7 to pull the roving; the other independent channels provide low-flow airflow, which is sprayed through the corresponding nozzle core 10 and main nozzle 7 to assist in pulling the fine yarn, thereby realizing the need for a single machine to process yarns of different specifications at the same time and efficiently completing the weft yarn introduction work in the weaving process.

[0037] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
