Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a rotatable and adjustable spray cone tube type main nozzle mounting base for looms. Background Technology

[0002] In the operation of a water-jet loom, the installation position and angle of the main nozzle play a crucial role in the effectiveness of air jet weft insertion. Existing main nozzle mounting seats for looms generally suffer from inconvenient adjustment. An existing patent, CN202644059U, describes a nozzle device for the weft insertion mechanism of a water-jet loom, comprising multiple nozzle assemblies. Each nozzle assembly includes a nozzle seat fixedly mounted on a mounting frame, a nozzle body mounted on the nozzle seat, and a nozzle needle installed within the nozzle body. The key feature is that at least six nozzle assemblies are provided. The nozzle needles in the first and second nozzle assemblies are located on the bisector of the opening formed by the warp threads of the water-jet loom, while the nozzle needles in the remaining nozzle assemblies are located on two horizontal lines parallel to the bisector of the opening formed by the warp threads. This invention allows the use of various weft yarns, increasing the woven patterns of the water-jet loom. Through structural improvements, it ensures the implementation of six or more nozzles.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: they can usually only be installed in a simple fixed manner, making it difficult to flexibly adjust the position and angle of the main nozzle according to different weaving needs. This leads to the inability to accurately control the airflow direction and intensity of the air jet weft insertion when the fabric type, yarn type, etc. change in actual production, which can easily result in unstable weft yarn flight and weft insertion failure, thereby affecting weaving quality and production efficiency. Therefore, we propose a rotatable and adjustable spray cone tube type main nozzle mounting base for looms to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotatable and adjustable main nozzle mounting base for a spray cone tube type loom. This solves the problem that existing technologies make it difficult to flexibly adjust the position and angle of the main nozzle according to different weaving needs. This results in the inability to accurately control the airflow direction and intensity of air jet weft insertion when the fabric type, yarn type, etc., change in actual production, which can easily lead to problems such as unstable weft flight and weft insertion failure.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a rotatable and adjustable main nozzle mounting base for a spray cone tube type loom, including a mounting base, a bearing plate rotatably connected to the top of the mounting base, and two support plate mechanisms fixedly connected in a linear array on the top surface of the bearing plate;

[0006] A servo motor B is fixedly connected to the outer side of the support plate mechanism. A bevel gear A is installed on the output shaft of the servo motor B. A nozzle support is rotatably connected to the inner side of the two support plate mechanisms. A bevel gear B is coaxially installed on the outer side of the nozzle support. The bevel gear B and the bevel gear A mesh and drive each other. Two nozzle assemblies are fixedly connected to the top of the nozzle support in opposite directions. An angle sensor is also fixedly connected to the top surface of the nozzle support.

[0007] Preferably, the outer side of the mounting base is fixedly connected with a support leg assembly, and the support leg assembly has four locations.

[0008] Preferably, the four support leg assemblies are fixedly connected to the four outer corners of the mounting base, and the four support leg assemblies together form a support structure for the mounting base.

[0009] Preferably, each of the four support leg assemblies has a mounting hole inside, a side plate mechanism is fixedly connected to the bottom surface of the mounting base, and a servo motor A is fixedly connected to the inner side of the side plate mechanism.

[0010] Preferably, a worm gear assembly is mounted on the rear output shaft of the servo motor A via a coupling, and a transmission shaft is rotatably connected to the center of the mounting base.

[0011] Preferably, a worm gear assembly is coaxially mounted at the bottom end of the drive shaft, and the worm gear assembly cooperates with the worm assembly for transmission.

[0012] Preferably, one side of the nozzle assembly is used to install the feed end, and the other side is used to spray material, and the nozzle assembly is connected to a high-pressure air pump.

[0013] Beneficial effects

[0014] This invention provides a rotatably adjustable main nozzle mounting base for a spray cone-shaped loom. Compared with the prior art, it has the following advantages:

[0015] The rotatable and adjustable main nozzle mounting base of the spray cone tube type loom is driven by a servo motor B, which drives a bevel gear A to mesh with a bevel gear B on the nozzle support. This allows the nozzle support to rotate easily, thereby adjusting the angle of the nozzle assembly. At the same time, an inclination sensor monitors and provides feedback on angle changes in real time, ensuring the accuracy of the adjustment. This enables precise control of the airflow direction for air jet weft insertion in actual production, regardless of the fabric type or yarn type. It effectively solves the problem of unstable weft flight and greatly improves the weaving quality.

[0016] This rotatable and adjustable main nozzle mounting base for a cone-shaped spray loom allows for horizontal adjustment of the bearing plate and nozzle assembly via a servo motor A, worm gear assembly, worm wheel assembly, and drive shaft. It also allows for adjustment of the nozzle assembly angle. This comprehensive and flexible adjustment function enables the main nozzle to quickly adjust to the optimal position and angle according to different weaving needs, precisely control the airflow intensity of air jet weft insertion, effectively avoid weft insertion failure, and significantly improve production efficiency.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6This utility model provides a technical solution: a rotatable and adjustable spray cone tube type main nozzle mounting base for a loom, including a mounting base 1, a bearing plate 2014 rotatably connected to the top of the mounting base 1, and two support plate mechanisms 3 fixedly connected in a linear array on the top surface of the bearing plate 2014.

[0026] A servo motor B301 is fixedly connected to the outer side of the support plate mechanism 3. A bevel gear A3011 is installed on the output shaft of the servo motor B301. A nozzle support 3012 is rotatably connected to the inner side of the two support plate mechanisms 3. A bevel gear B3013 is coaxially installed on the outer side of the nozzle support 3012. The bevel gear B3013 meshes with the bevel gear A3011 for transmission. Two nozzle assemblies 3014 are fixedly connected to the top of the nozzle support 3012 in opposite directions. An tilt sensor 3015 is also fixedly connected to the top surface of the nozzle support 3012.

[0027] The support plate 2014 is rotatably connected to the top of the mounting base 1. The support plate mechanism 3 on the support plate 2014 is connected to the servo motor B301. The bevel gear A3011 of its output shaft meshes with the bevel gear B3013 of the nozzle support 3012, driving the nozzle support 3012 to rotate, thereby adjusting the angle of the nozzle assembly 3014. The tilt sensor 3015 can monitor the angle change, realizing flexible and precise adjustment of the angle of the nozzle assembly 3014.

[0028] See Figures 1-3 The mounting base 1 is fixedly connected to the outer side of the support leg assembly 101, which has four parts;

[0029] The four support legs 101 on the outside of the mounting base 1 provide stable support for the mounting base 1, ensuring that the entire mounting base 1 remains stable during operation and preventing shaking that could affect the operation of the nozzle assembly 3014.

[0030] See Figures 2-4 The four support leg assemblies 101 are fixedly connected to the four outer corners of the mounting base 1, and the four support leg assemblies 101 together form a support structure for the mounting base 1.

[0031] The four support leg assemblies 101 located at the four corners of the outer side of the mounting base 1 form a support structure, which evenly distributes the weight of the mounting base 1 and the upper part, further enhancing the stability of the mounting base 1 and ensuring the smooth operation of the main nozzle mounting base 1.

[0032] See Figures 5-6 The four support legs 101 are provided with mounting holes 1011 inside. The bottom surface of the mounting base 1 is fixedly connected to the side plate mechanism 2, and the inner side of the side plate mechanism 2 is fixedly connected to the servo motor A201.

[0033] The mounting holes 1011 inside the support assembly 101 facilitate the connection and fixation of the mounting base 1 to external equipment. The servo motor A201 on the side plate mechanism 2 provides power for subsequent transmission and is the power source basis for realizing the rotation adjustment of the bearing plate 2014.

[0034] See Figures 1-2 A worm gear assembly 2011 is mounted on the rear output shaft of the servo motor A201 via a coupling, and a drive shaft 2012 is rotatably connected to the center of the mounting base 1.

[0035] The worm gear assembly 2011 on the rear output shaft of the servo motor A201 works in conjunction with the worm wheel assembly 2013 at the bottom of the transmission shaft 2012 to transmit the rotational motion of the servo motor A201 to the transmission shaft 2012, thereby driving the bearing plate 2014 to rotate and realizing the adjustment of the horizontal position of the bearing plate 2014 and the nozzle assembly 3014 on it.

[0036] See Figures 3-5 A worm gear assembly 2013 is coaxially mounted at the bottom end of the drive shaft 2012, and the worm gear assembly 2013 cooperates with the worm assembly 2011 for transmission.

[0037] The worm gear assembly 2013 and the worm shaft assembly 2011 work together to ensure the stability and accuracy of power transmission, making the rotation adjustment of the bearing plate 2014 more stable and precise, which is conducive to the precise control of the position of the nozzle assembly 3014.

[0038] See Figures 1-2 One side of the nozzle assembly 3014 is used to install the feed end, and the other side is used to spray the material. The nozzle assembly 3014 is connected to a high-pressure air pump.

[0039] The nozzle assembly 3014 is connected to a high-pressure air pump, allowing material to be fed from one side and ejected from the other, thus realizing the air jet weft insertion function. It is the key actuator of the main nozzle mounting seat 1 to complete the air jet weft insertion operation in textile production.

[0040] During operation, the mounting base 1 serves as the basic component of the entire device. Four support leg assemblies 101 are fixedly connected to its four outer corners. Each support leg assembly 101 has a mounting hole 1011 inside. Through these mounting holes 1011, bolts and other connectors can be used to securely connect the mounting base 1 to external equipment, thereby providing a stable mounting foundation for the entire main nozzle mounting base 1. The four support leg assemblies 101 together form a support structure for the mounting base 1, evenly distributing the weight of the mounting base 1 and the upper components, ensuring that the entire mounting base 1 remains stable during operation and preventing shaking.

[0041] A side plate mechanism 2 is fixedly connected to the bottom surface of the mounting base 1. A servo motor A201 is fixedly connected to the inner side of the side plate mechanism 2. A worm gear assembly 2011 is mounted on the rear output shaft of the servo motor A201 via a coupling. A transmission shaft 2012 is rotatably connected to the inner center position of the mounting base 1. A worm wheel assembly 2013 is coaxially mounted on the bottom end of the transmission shaft 2012. The worm wheel assembly 2013 and the worm gear assembly 2011 cooperate to transmit power. When it is necessary to adjust the horizontal position of the bearing plate 2014, the servo motor A201 is started. The output shaft of the servo motor A201 drives the worm gear assembly 2011 to rotate. The worm gear assembly 2011 and the worm wheel assembly 2013 mesh with each other, transmitting the rotational motion of the worm gear assembly 2011 to the transmission shaft 2012. The rotation of the transmission shaft 2012 drives the bearing plate 2014, which is rotatably connected to its top, to rotate, thereby realizing the adjustment of the horizontal position of the bearing plate 2014 and the nozzle assembly 3014 above it.

[0042] Two support plate mechanisms 3 are fixedly connected in a linear array on the top surface of the support plate 2014. A servo motor B301 is fixedly connected to the outside of the support plate mechanism 3. A bevel gear A3011 is installed on the output shaft of the servo motor B301. A nozzle support 3012 is rotatably connected to the inside of the two support plate mechanisms 3. A bevel gear B3013 is coaxially installed on the outside of the nozzle support 3012. The bevel gear B3013 meshes with the bevel gear A3011 for transmission. When it is necessary to adjust the angle of the nozzle assembly 3014, the servo motor B301 is started. The output shaft of the servo motor B301 drives the bevel gear A3011 to rotate. The bevel gear A3011 and the bevel gear B3013 mesh with each other, thereby driving the nozzle support 3012 to rotate around its rotation axis. The two nozzle assemblies 3014 fixedly connected to each other at the top of the nozzle support 3012 also rotate accordingly, realizing the adjustment of the angle of the nozzle assembly 3014.

[0043] An angle sensor 3015 is also fixedly connected to the top surface of the nozzle support 3012. During the process of rotating the nozzle support 3012 to adjust the angle of the nozzle assembly 3014, the angle sensor 3015 monitors the angle change of the nozzle support 3012 in real time and feeds the monitoring data back to the control system. The document does not mention the specific control system, but it is assumed to exist. The control system compares and analyzes the preset angle parameters with the data fed back by the angle sensor 3015, and then precisely controls the operation of the servo motor B301 to achieve precise adjustment of the angle of the nozzle assembly 3014.

[0044] One side of the nozzle assembly 3014 is used to install the feed end, and the other side is used to spray the material. The nozzle assembly 3014 is connected to a high-pressure air pump. After the position and angle of the nozzle assembly 3014 are adjusted, the high-pressure air pump delivers high-pressure airflow to the nozzle assembly 3014, carrying the weft yarn into the feed end of the nozzle assembly 3014 and spraying it out from the other side, realizing the air-jet weft insertion function and completing the key operation steps in textile production.

[0045] In summary, the device, by providing the support plate mechanism 3, enables the nozzle support 3012 to be rotated and installed.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
