Description

Technical Field

[0001] This utility model belongs to the technical field of loom parts, and more specifically, it relates to an auxiliary nozzle for an air-jet loom that can be quickly disassembled and assembled. Background Technology

[0002] In the textile industry, the air-jet loom is a widely used weaving equipment. Its working principle is to use compressed air to introduce the weft yarn into the shed formed by the warp yarn, thereby realizing the weaving of the fabric. As one of the key components of the air-jet loom, the auxiliary nozzle is arranged at intervals along the flight path of the weft yarn. It sprays high-speed airflow to relay the weft yarn in flight, supplement the energy required for the weft yarn to fly, and ensure that the weft yarn can accurately, stably and quickly pass through the entire shed to complete the weaving action.

[0003] Based on existing technology, it has been found that the existing auxiliary nozzles for air-jet looms have some shortcomings. Currently, the mainstream auxiliary nozzles generally adopt an external thread connection structure to be assembled and fixed with the air-jet loom body. However, the threaded connection method requires manual loosening or tightening. Especially when textile enterprises perform batch maintenance on air-jet looms or need to replace multiple sets of auxiliary nozzles due to production needs, this manual disassembly and assembly method will consume a lot of labor time, resulting in extended equipment downtime for maintenance and affecting the operating efficiency of textile production lines. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a quick-disassembly auxiliary nozzle for air-jet looms. This solves the problem that current mainstream auxiliary nozzles generally use an external threaded connection structure to be assembled and fixed to the air-jet loom body. However, the threaded connection requires manual loosening or tightening, which is particularly time-consuming in textile enterprises when performing batch maintenance on air-jet looms or replacing multiple sets of auxiliary nozzles due to production needs. This leads to extended downtime for equipment maintenance and affects the operational efficiency of the textile production line.

[0005] The first aspect of this utility model provides a quick-detachable auxiliary nozzle for an air-jet loom, achieved through the following specific technical means: A quick-release auxiliary nozzle for an air-jet loom, comprising: The mounting part includes a prefabricated component with an external thread at its bottom. A connecting part is provided on the mounting part, with a lifting component located inside the prefabricated component. The lifting component slides within a movable groove in the prefabricated component, and the bottom of the lifting component contacts a spring in the movable groove. A fixing tube at the outer end of the lifting component is inserted into a bottom groove within the prefabricated component. An air guide is provided on the mounting part, with its base engaged in a slot within the prefabricated component. A limiting plate at the outer end of the base abuts against the inner side of the prefabricated component, and the base is positioned above the lifting component. The interface within the base is inserted into a connector at the outer end of the lifting component.

[0006] Furthermore, the mounting part includes: a movable groove and a spring; the movable groove is located at the rear inner end of the precast component; the spring is fitted onto a circular rod within the movable groove.

[0007] Furthermore, the mounting part includes: a bottom groove and a slot; the bottom groove is disposed on the inner side of the bottom of the precast component; the slot is disposed on the front side of the top of the precast component.

[0008] Furthermore, the connecting part includes: a lifting component and a connector; the lifting component has a rectangular structure; the connector is located at the upper front end of the lifting component, and the connector has a conical structure and a hollow interior.

[0009] Furthermore, the connecting part includes: a fixing tube and a pull ring; the fixing tube is disposed at the bottom of the lifting component, and the fixing tube and the connector are on the same axis; the pull ring is fixedly installed on the rear side of the lifting component.

[0010] Furthermore, the air guide includes: a base, a limiting plate, and an interface; the base is a cylindrical structure; the limiting plate is fixedly installed on the lower outer end of the base; the interface is opened on the inner bottom side of the limiting plate, and the interior of the interface is a conical structure.

[0011] Furthermore, the air guide includes a nozzle and air holes; the nozzle is located on the top of the base; the air holes are disposed on both sides of the top of the nozzle.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this device, a movable lifting component is installed. A slot is set on the top of the prefabricated component, and a limiting plate is set on the outer end of the base. When disassembling the air guide, simply press the pull ring to drive the lifting component down, so that the connector and interface are separated, and the air guide can be directly taken out from the slot. When installing the air guide, press the lifting component down to lock the base into the slot, and then release the lifting component. The spring can push the lifting component to reset, realizing the automatic insertion and positioning of the connector and interface. This can improve the efficiency of disassembly and assembly of a single set of auxiliary nozzles and greatly shorten the downtime of the air-jet loom for maintenance.

[0013] 2. In this device, a conical joint is set at the top of the lifting component and a conical interface is set at the lower end of the base. When changing different types of nozzles, there is no need to replace or modify the prefabricated parts of the installation part. The conical joint of the lifting component can be adapted to different types of air guides, ensuring a sealed fit between the joint and the interface. This allows for quick adaptation to various types of air guides, thus meeting the weaving needs of different fabrics. At the same time, the spring continuously pushes the lifting component, making the conical joint and the conical interface fit tightly together, forming a self-tightening sealing structure, avoiding sealing gaps caused by vibration. The insertion and matching of the fixed pipe and the bottom groove, and the abutment positioning of the limiting plate and the inner side of the prefabricated part, can further limit the displacement of the air guide, ensuring that the air path remains stable and unobstructed during the weaving process.
