Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and more specifically to a straight-tube loom nozzle. Background Technology

[0002] Air-jet looms are one of the important types of modern shuttleless looms. Their core feature is that they use high-speed compressed air as a carrier to draw the weft yarn through the shed formed by the warp yarn. The nozzle is the key actuator of the air-jet loom. As air-jet looms develop towards higher speed, wider width, energy saving and high adaptability, the shortcomings of the straight cylindrical main nozzle are becoming increasingly prominent.

[0003] A search revealed Chinese patent CN208362595U, which discloses a loom nozzle. This device is easy to use, provides clean filtration, and has adjustable water speed, enabling high-speed yarn transport to ensure normal operation of the loom and improve yarn quality. However, with long-term use, viscous substances tend to adhere to the inner wall of the nozzle, and the high-speed flowing liquid inside can cause erosion and wear on the inner wall. If not treated, this will affect the normal use of the nozzle. Utility Model Content

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-5 This utility model provides a straight-tube type loom nozzle, including a nozzle housing 2, a fixing seat 1 on the outer wall of the nozzle housing 2, a water pipe connector 3 threadedly connected to one end of the nozzle housing 2, an annular groove 7 on the inner circumference of the nozzle housing 2, a nozzle inner tube 8 slidably connected in the annular groove 7, two symmetrical guide grooves 9 on the inner circumference of the annular groove 7, and a guide strip 10 welded to the outer circumference of the nozzle inner tube 8 to cooperate with the two guide grooves 9. A fixing component is provided between the nozzle housing 2 and the nozzle inner tube 8 to fix the two. One end of the inner cavity of the nozzle housing 2 is a circular tube structure, and the other end is a conical structure. The inner diameter of the circular tube structure end is much larger than the diameter of the small end of the conical structure.

[0024] Specifically, once the locking cover 12 is disengaged from the square opening 13, the nozzle inner tube 8 can be pulled, causing the nozzle inner tube 8 to slide along the inner wall of the nozzle outer shell 2. Once the nozzle inner tube 8 is disengaged from the nozzle outer shell 2, the nozzle inner tube 8 can be removed for replacement or cleaning.

[0025] By designing the nozzle as a double-layered detachable structure consisting of a nozzle housing 2 and a nozzle inner tube 8, the problem of viscous substances adhering to the inner wall of the nozzle and wear after long-term use can be solved without completely disassembling the nozzle.

[0026] In this utility model, the top inner wall and the bottom inner wall of the square opening 13 are provided with limiting grooves 15. A top plate 14 is slidably connected in the two limiting grooves 15. Multiple springs 16 with the same spacing are welded on one side inner wall of the two limiting grooves 15. The other end of the multiple springs 16 is fixed to one side of the top plate 14.

[0027] Specifically, when it is necessary to clean the inner wall of the nozzle, first disconnect the water pipe connector 3 at one end of the nozzle, and then press the top plate 14 outside the nozzle housing 2 through the round hole on one side of the fixed base 1. During the pressing of the top plate 14, it slides along the square opening 13, while squeezing the spring 16 to compress it.

[0028] The top plate 14 allows for easy disengagement of the locking cover 12 and the square opening 13 by staff, making the structure simple and convenient to use.

[0029] Further fixing components include a groove 11 formed on the guide bar 10, a locking cover 12 slidably connected in the groove 11, a spring 17 welded between one inner wall of the locking cover 12 and one inner wall of the groove 11, and two square openings 13 formed on the inner circumference of the nozzle housing 2 to cooperate with the groove 11, with the locking cover 12 partially embedded in the square openings 13.

[0030] During the movement of the top plate 14, it will press the locking cover 12 located in the square opening 13, thereby causing the locking cover 12 to slide along the slide groove 11, while the locking cover 12 compresses the second spring 17.

[0031] The locking cover 12 and the square opening 13 that work together with it can fix the nozzle inner tube 8 into the nozzle outer shell 2 to prevent displacement of the two during operation, thus affecting the normal operation of the device.

[0032] In this utility model, a clearance hole 4 is provided on the fixed base 1, and a threaded groove 6 that cooperates with the clearance hole 4 is provided on one side of the outer wall of the nozzle housing 2. A screw 5 is threadedly connected in the threaded groove 6, and the screw 5 passes through the clearance hole 4.

[0033] Specifically, when it is necessary to remove the nozzle housing 2, first use a tool to remove the screw 5 so that it is separated from the threaded groove 6 and the clearance hole 4, and then the nozzle housing 2 can be removed along the fixing seat 1.

[0034] In this utility model, grooves are provided on both inner walls of the sliding groove 11, and protrusions are provided on both outer walls of the locking cover 12 to cooperate with the grooves. The protrusions slide in the grooves to form a limit.

[0035] The use of this utility model involves the following steps:

[0036] S1: When it is necessary to clean the inner wall of the nozzle, first disconnect the water pipe connector 3 at one end of the nozzle, and then press the top plate 14 outside the nozzle housing 2 through the round hole on one side of the fixed base 1. During the pressing of the top plate 14, it slides along the square opening 13 and compresses the spring 16. During the movement of the top plate 14, it will press the locking cover 12 located in the square opening 13, so that the locking cover 12 slides along the slide groove 11. At the same time, the locking cover 12 compresses the spring 2 17.

[0037] S2: When the locking cover 12 is disengaged from the square opening 13, the nozzle inner tube 8 can be pulled, so that the nozzle inner tube 8 slides along the inner wall of the nozzle housing 2. When the nozzle inner tube 8 is disengaged from the nozzle housing 2, the nozzle inner tube 8 can be removed for replacement or cleaning.

[0038] S2: When it is necessary to remove the nozzle housing 2, first use a tool to remove the screw 5 so that it is separated from the threaded groove 6 and the clearance hole 4, and then the nozzle housing 2 can be removed along the fixing seat 1.
