[0030] The following will be further described in detail with reference to the attached Figures 1-3 This application will be further described in detail.

[0031] The embodiment of the present application discloses a nozzle structure of an air-jet loom. Please refer toFigures 1 to 3 , including a main pipe 1, the end of the main pipe 1 is threadedly connected with a mounting head 2, the middle of the upper surface of the mounting head 2 is fixedly connected with a fixing seat 3, a spherical connecting groove is formed in the fixing seat 3, a rotatable spherical head 4 is connected in the connecting groove, the upper part of the spherical head 4 is fixedly connected with a connecting pipe 5, and the end of the connecting pipe 5 is threadedly connected with a spray pipe 6;

[0032] Two shaping hoses 7 are symmetrically arranged and communicated between the middle part of the side wall of the connecting pipe 5 and the mounting head 2. The fixing seat 3 added on the mounting head 2 and the connecting pipe 5 are rotatably connected through the spherical head, and a shaping hose 7 is also communicated between the connecting pipe 5 and the mounting head 2, so that the spray pipe 6 can be flexibly rotated and adjusted according to needs. Furthermore, the user can adjust the angle of the nozzle 602 in real time according to the actual processing needs and the feedback of the actual processing effect, greatly simplifying the installation and adjustment process and ensuring the processing effect.

[0033] The spray pipe 6 includes an intermediate pipe 601. The lower end of the intermediate pipe 601 is threadedly connected with the connecting pipe 5, and the upper end of the connecting pipe 5 is also threadedly connected with a nozzle 602. At the same time, both ends of the shaping hose 7 are threadedly connected with the connecting pipe 5 and the mounting head 2 respectively. The threaded connection method between each component is convenient for disassembly and assembly, greatly simplifying the installation process, facilitating cleaning, and saving time and effort.

[0034] The nozzle 602 is a telescopic sleeve structure and can be telescoped according to needs, which can further increase the adjustable range of the nozzle structure of the present application.

[0035] A damping sheet 301 is arranged between the spherical head 4 and the connecting groove. The addition of the damping sheet 301 can increase the friction force between the spherical head 4 and the connecting groove to ensure that after the connecting pipe 5 is rotated to the required position, its fixed relative position can be maintained, thereby ensuring the stability of the angle of the nozzle 602 after adjustment.

[0036] The shaping hose 7 is a corrugated pipe made of plastic. The shaping hose 7 plays a role in connecting the mounting head 2 and the connecting pipe 5. The shaping hose 7 with a corrugated pipe structure made of plastic has excellent flexibility and plasticity, which can ensure the smooth flow of the air flow transmitted from the main pipe 1 to the final nozzle 602 during the rotation adjustment process of the connecting pipe 5 and ensure the normal spraying of the air flow.

[0037] The implementation principle of the nozzle structure of a jet loom in an embodiment of the present application is as follows: When the present application is used, the connecting pipe 5 can be rotated first according to the processing requirements, so that the spray pipe 6 can be flexibly rotated and adjusted according to needs. Subsequently, the angle of the nozzle 602 can be adjusted in real time according to the changes in the actual processing needs and the feedback of the actual processing effect. The adjustment process is simple, and the threaded connection method between each component is convenient for disassembly and assembly, greatly simplifying the installation process, facilitating cleaning, and saving time and effort.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
