Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, and in particular to an air-jet loom that facilitates the cleaning of lint from the needle holes. Background Technology

[0002] Air-jet looms are high-efficiency weaving equipment that uses compressed air as the weft insertion medium. They mainly consist of a frame, shedding mechanism, warp feeding mechanism, weft insertion nozzles, auxiliary nozzles, beat-up mechanism, take-up mechanism, and control system. During operation, the high-speed airflow from the nozzles carries the weft yarn through the shed formed by the warp yarns, achieving rapid and stable weft insertion. Compared to traditional shuttle looms, air-jet looms offer advantages such as high speed, low noise, minimal mechanical wear, and relatively low energy consumption. They are particularly suitable for weaving lightweight yarns such as synthetic filaments and staple fibers, and are widely used in home textiles, clothing, and industrial fabrics, boasting significant advantages in automation, weaving precision, and production efficiency.

[0003] Traditional air-jet looms often suffer from the problem of needle holes becoming clogged with fiber debris, oil, and dust during long-term operation. Due to the extremely small and densely distributed nozzle orifices, traditional maintenance typically relies on operators manually clearing each one with a thin metal needle bar. This is not only time-consuming and labor-intensive, but also prone to causing scratches on the orifice walls or deformation due to uneven force, leading to deviation in airflow direction and reduced airflow speed. Consequently, weft insertion becomes unstable, and weft breaks occur frequently, severely impacting fabric quality and production rhythm. Furthermore, manual cleaning is insufficient to completely remove the oil and fine fibers adhering to the orifices, causing recurring clogging problems. This increases maintenance frequency and downtime, reducing the overall utilization rate of the equipment and the level of automated production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air-jet loom for easy cleaning of lint at needle holes, comprising a machine body, wherein a take-up roller is rotatably mounted at the front of the machine body for taking up the finished woven fabric, and a support frame, wherein the support frame is integrated and installed at the needle hole position inside the machine body; a translation carriage, wherein the translation carriage is slidably installed inside a track inside the support frame and performs reciprocating lateral movement inside the track of the support frame; and a dredging assembly, wherein the dredging assembly includes an electric push rod fixedly installed on one side of the translation carriage, and a dredging rod fixed at the lower part of the electric push rod for inserting into the needle hole of the machine body to perform a dredging action.

[0006] In at least some embodiments, the translation vehicle includes a housing slidably mounted inside the support frame guide rail, and a motor is fixedly installed inside the housing for driving the housing to move laterally.

[0007] In at least some embodiments, a drive wheel is fixedly connected to the output end of the motor, and a first guide wheel rotatably mounted on the upper part of the housing is engaged with the drive wheel.

[0008] In at least some embodiments, the draining rod has a hook groove on its outside, which is used to hook cotton fibers when the draining rod rotates.

[0009] In at least some embodiments, the support frame has toothed rails on both sides, the first guide wheel is meshed with one of the toothed rails, the transmission wheel rotatably mounted on the upper part of the housing is meshed with the drive wheel and the second guide wheel rotatably mounted on the upper part of the housing on both sides, and the other toothed rail is meshed with the second guide wheel.

[0010] In at least some embodiments, the upper part of the square rod rotatably mounted inside the housing is fixedly connected to the transmission wheel, and the unblocking rod is rotatably mounted on the lower part of the support arm fixed to the output end of the electric push rod. The unblocking rod is slidably sleeved on the lower part of the square rod. In use, the motor synchronously drives the housing to move laterally and the unblocking rod to rotate and unblock.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a support frame and a traverse structure are integrated into the pinhole positions inside the machine body to achieve automated pinhole cleaning. The traverse is slidably installed in the support frame track and can move back and forth in the track, sequentially corresponding to multiple nozzle pinhole positions under the drive of the control system. An electric push rod is fixedly installed on one side of the traverse.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example, according to Figures 1-4 As shown in the figure, this utility model provides an air-jet loom for easy cleaning of lint at the needle holes, including a machine body 1, a take-up roller 2 rotatably mounted at the front of the machine body 1 for taking up the finished fabric, a support frame 3 integrated into the needle hole position inside the machine body 1; a translation carriage 5 slidably mounted inside the track inside the support frame 3 and reciprocating laterally within the track of the support frame 3; and a dredging component 6, which includes an electric push rod 601 fixedly mounted on one side of the translation carriage 5, and a dredging rod 603 fixed at the lower part of the electric push rod 601 for inserting into the needle hole of the machine body 1 to perform a dredging action.

[0017] The aforementioned air-jet loom, which facilitates the cleaning of lint at the needle holes, achieves automated needle hole cleaning by integrating a support frame 3 and a translation carriage 5 structure at the needle hole location inside the machine body 1. The translation vehicle 5 is slidably installed in the track of the support frame 3, and can move back and forth in the track, corresponding to the positions of multiple nozzle pinholes in sequence under the drive of the control system. An electric push rod 601 is fixedly installed on one side of the translation vehicle 5. The extension and retraction of the electric push rod 601 drives the unblocking rod 603 at the lower end to perform a reciprocating insertion motion, thereby mechanically unblocking and removing the lint, fiber debris and dust inside the pinhole. During operation, the electric actuator 601 automatically extends and retracts according to the set program, and works in conjunction with the lateral movement of the translation vehicle 5 to achieve continuous automatic cleaning of multiple nozzle holes, avoiding the inefficiency of manually clearing each hole one by one.

[0018] In this embodiment, the translation vehicle 5 includes a housing 501 that is slidably installed inside the guide rail of the support frame 3. A motor 502 is fixedly installed inside the housing 501 for driving the housing 501 to move laterally. A drive wheel 503 is fixedly connected to the output end of the motor 502. A first track wheel 504 rotatably installed on the upper part of the housing 501 is engaged with the drive wheel 503. A hook groove 604 is provided on the outside of the unblocking rod 603. When the unblocking rod 603 rotates, the hook groove 604 is used to hook cotton wool.

[0019] The translation carriage 5 moves laterally via a housing 501 located inside the guide rail of the support frame 3. A motor 502 inside the housing 501 serves as the power source, with its output fixedly connected to a drive wheel 503. The drive wheel 503 meshes with a first guide wheel 504 mounted on the upper part of the housing 501, thus driving the entire translation carriage 5 to move smoothly back and forth along the guide rail. During the cleaning process, the motor 502 drives the unblocking rod 603 to insert and rotate at the needle hole position of the air-jet loom. The hook groove 604 on the outside of the unblocking rod 603 effectively hooks and removes impurities such as cotton wool and fiber debris adhering to the needle hole during rotation, achieving efficient cleaning. This structure, driven by the motor 502 and in conjunction with the mechanical hook groove 604, automatically unblocks the needle hole and removes lint, improving cleaning efficiency and the stability of the loom operation.

[0020] In this embodiment, toothed rails 4 are respectively provided on both sides of the support frame 3. The first guide wheel 504 is meshed with one of the toothed rails 4. The transmission wheel 505, which is rotatably mounted on the upper part of the housing 501, is meshed with the drive wheel 503 and the second guide wheel 506, which is rotatably mounted on the upper part of the housing 501, respectively. The other toothed rail 4 is meshed with the second guide wheel 506. The upper part of the square rod 605, which is rotatably mounted inside the housing 501, is fixedly connected to the transmission wheel 505. The lower part of the support arm 602, which is fixed to the output end of the electric push rod 601, is rotatably mounted with a dredging rod 603. The dredging rod 603 is slidably sleeved on the lower part of the square rod 605. In use, the motor 502 synchronously drives the housing 501 to move laterally and the dredging rod 603 to rotate and dredge.

[0021] By setting a translation cart 5 structure inside the guide rail of the support frame 3, the automated precision cleaning of nozzle pinholes is achieved. The translation cart 5 consists of a housing 501, a drive motor 502, a drive wheel 503, and a traveling wheel. The motor 502 inside the housing 501 serves as the power source, and its output end is fixedly connected to the drive wheel 503. The drive wheel 503 meshes with the first traveling wheel 504 installed on the upper part of the housing 501, thereby driving the housing 501 to move smoothly and controllably back and forth along the guide rail of the support frame 3, so that the unblocking component 6 can sequentially perform positioning operations on multiple jet pinholes. During the cleaning phase, motor 502 drives the unblocking rod 603 to perform precise insertion and rotation. The hook groove 604 on the outside of the unblocking rod 603 can generate a cutting and hooking action during rotation, effectively rolling out impurities such as cotton wool, fiber debris, and oil deposits that are blocking the needle hole, thereby restoring the nozzle channel to a clear state. Through the drive of motor 502, the guidance of the travel wheel, and the mechanical cooperation of hook groove 604, automatic unblocking and deep cleaning of needle holes are achieved, avoiding the problems of low efficiency and damage to the hole wall of traditional manual needle bar unblocking, greatly improving cleaning accuracy and loom operation stability, and ensuring the continuous and efficient air-jet weft insertion.

[0022] The working principle of this utility model is as follows: By integrating a support frame 3 and a translation carriage 5 at the needle hole position inside the machine body 1, an automated needle hole cleaning function is achieved. The translation carriage 5 is slidably installed in the track of the support frame 3 and can move back and forth in the track, corresponding to multiple nozzle needle hole positions in sequence under the drive of the control system. An electric push rod 601 is fixedly installed on one side of the translation carriage 5. The extension and retraction of the electric push rod 601 drives the unblocking rod 603 at the lower end to perform a reciprocating insertion force, thereby mechanically unblocking and removing the fluff, fiber debris and dust inside the needle hole. During the operation, the electric push rod 601 automatically extends and retracts according to the set program, and cooperates with the lateral movement of the translation carriage 5 to achieve continuous automatic cleaning of multiple nozzle holes, avoiding the inefficiency of manual unblocking hole by hole. This structure not only ensures the smooth flow of air jet channels, maintains stable airflow and weft insertion accuracy, but also significantly reduces downtime maintenance time, improves the automation level and production efficiency of the loom, and extends the service life of the nozzle assembly.
