Description

Technical Field

[0001] The invention belongs to the field of water jet looms, and in particular relates to a nozzle structure of a water jet loom. Background Art

[0002] A water jet loom is a machine that uses a water jet to separate the warp and weft yarns to weave fabrics. It is usually composed of a nozzle, a sprinkler, a shuttle, a rapier, a yarn guide, a cam mechanism, an electronic control and a pool. When weaving, the warp yarn is suspended from the shaft and sent to the rapier through the yarn guide, the bite and other parts. Then the rapier drives the warp yarn up and down to separate the warp yarn. At this time, the water jet is injected through the nozzle and the sprinkler, and drives the weft yarn to move up and down. The nozzle is the most important component of the water jet loom, which can separate the warp and weft yarns and ensure the stability of the components during operation.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0034] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a nozzle structure of a water jet loom includes a bottom bracket 1, an outer sleeve 2 and a conveying assembly 3, wherein the outer sleeve 2 is provided on one side of the upper end of the bottom bracket 1, and the conveying assembly 3 is fixedly installed inside the outer sleeve 2, and a clamping mechanism 4 is fixedly installed inside the outer sleeve 2, and the clamping mechanism 4 includes an outer frame 41, a rotating frame 43 and an extrusion plate 44, the outer frame 41 is fixedly installed inside the outer sleeve 2, the rotating frame 43 is symmetrically rotatably installed on the upper and lower ends of the inner wall of the outer frame 41, and the extrusion plate 44 is fixedly installed on the side of the rotating frame 43, and the conveying assembly 3 includes a feeding pipe 31, the feeding pipe 31 is arranged inside the outer sleeve 2, and the extrusion plate 44 is in extrusion contact with the outer wall of the feeding pipe 31.

[0035] During use, the conveying component 3 is installed inside the outer sleeve 2, and then the liquid to be sprayed is conveyed through the use of the conveying component 3, and the material of the loom on the side is sprayed. When the fabric on the side away from the conveying component 3 needs to be processed, the feeding pipe 31 of the conveying component 3 can be squeezed by using the clamping mechanism 4. Through the rotation of the rotating frame 43, the two groups of squeezing plates 44 will rotate toward the middle end at the same time, and the two groups of squeezing plates 44 will squeeze the outer wall of the feeding pipe 31 of the conveying component 3 at the same time. By changing the outer diameter of the conveying component 3 itself, the internal pressure of the conveying component 3 is changed, so as to control the impact force of the liquid sprayed by the conveying component 3, thereby realizing the change of the overall working range of the conveying component 3.

[0036] By the attached Figure 3 As shown, in this embodiment, the clamping mechanism 4 also includes a protrusion frame 42 and a driving assembly 45. The protrusion frame 42 is symmetrically fixedly installed on the inner wall of the outer frame 41, and the driving assembly 45 is fixedly installed inside the protrusion frame 42. The protrusion frame 42 is rotatably connected to the rotating frame 43.

[0037] During use, the driving assembly 45 is used to provide power for the operation of the rotating frame 43. When the clamping mechanism 4 is used as a whole, the components of the driving assembly 45 can be controlled by the control box on the side of the control device, so that the operation of the driving assembly 45 can be automatically carried out without the need for staff to waste time on controlling the rotation of the extrusion plate 44, thereby simplifying the operating steps of the equipment itself.

[0038] By the attached Figure 4 As shown, in this embodiment, the driving assembly 45 includes a driving rod 451, a worm wheel 452, a worm 453, a linkage rod 454 and a driving motor 455. The driving rod 451 is rotatably installed inside the raised frame 42, and the end of the driving rod 451 is fixedly connected to the rotating frame 43. The linkage rod 454 is rotatably installed on the side of the driving rod 451 inside the raised frame 42, the worm wheel 452 is fixedly installed outside the driving rod 451, and the worm 453 is fixedly installed outside the linkage rod 454. The worm 453 is meshingly connected with the worm wheel 452, and the driving motor 455 is fixedly installed inside the raised frame 42 at the top of the linkage rod 454, and the output end of the driving motor 455 is fixedly connected to the end of the linkage rod 454.

[0039] During use, the driving motor 455 is started and operated to provide power for the rotation of the linkage rod 454, and then the linkage rod 454 will drive the worm 453 to rotate. By utilizing the meshing and irreversible characteristics between the worm 453 and the worm wheel 452, the driving rod 451 will stably drive the side rotating frame 43 and the extrusion plate 44 to rotate synchronously, thereby extruding the outer wall of the conveying assembly 3 at the bottom end of the extrusion plate 44.

[0040] By the attached Figure 5 As shown, in this embodiment, the conveying assembly 3 also includes a connecting ring 32 and a main nozzle 33. The connecting ring 32 is fixedly installed at the end of the feeding pipe 31, the extrusion plate 44 is in extrusion contact with the outer wall of the feeding pipe 31, and the main nozzle 33 is arranged at the top of the connecting ring 32.

[0041] During use, the main nozzle 33 is connected to the connecting ring 32 to complete the combination of the components. After that, the required liquid is input into the feeding pipe 31 through the use of the feeding pipe 31, and then sprayed in conjunction with the main nozzle 33 to process the material in the textile machine. During the operation of the extrusion plate 44, the outer surface of the feeding pipe 31 will be squeezed to reduce the overall outer diameter of the feeding pipe 31, so as to make the overall impact force of the conveying component 3 greater and increase the working range of the conveying component 3 itself.

[0042] By the attached Figure 5As shown, in this embodiment, the conveying component 3 also includes a threaded end 34, an engaging groove 35, a mounting groove 36 and a connecting component 37. The connecting ring 32 is provided with an engaging groove 35, and the end of the main nozzle 33 is fixedly installed with a threaded end 34, and the threaded end 34 is threadedly connected to the engaging groove 35. The outer sleeve 2 is provided with a mounting groove 36 outside the connecting ring 32, and the connecting component 37 is fixedly installed on the upper surface of the bottom bracket 1.

[0043] During use, by using the mounting groove 36, the connecting ring 32 can be stably installed inside the outer sleeve 2, and by the cooperation between the main nozzle 33 and the threaded end 34, the threaded end 34 can be turned into the engagement groove 35 inside the connecting ring 32, thereby completing the rapid installation and positioning of the main nozzle 33, speeding up the disassembly and assembly speed of the equipment, and when in use, the main nozzles 33 of different specifications can be replaced according to the actual spraying range, simplifying the operating difficulty when using the components.

[0044] By the attached Figure 6 As shown, in this embodiment, the connecting assembly 37 also includes a matching bin 371, a connecting hose 372 and a conveying hose 373. The matching bin 371 is fixedly mounted on the upper surface of the bottom bracket 1, the conveying hose 373 is fixedly mounted on the top of the matching bin 371, the connecting hose 372 is fixedly mounted on the side of the matching bin 371, and the end of the connecting hose 372 is fixedly connected to the end of the feeding pipe 31.

[0045] During use, the required liquid is input into the matching chamber 371 through the use of the delivery hose 373 and the pump body at the end of the delivery hose 373, and then the liquid is input into the feeding pipe 31 through the use of the connecting hose 372, so as to facilitate the subsequent spraying of the main nozzle 33. The overall length of the connecting hose 372 is limited, so that the positions of the outer sleeve 2 and the delivery assembly 3 can be adjusted in coordination with the operation of other components.

[0046] By the attached Figure 6 As shown, in this embodiment, the nozzle structure also includes a moving mechanism 5, which is used to push the outer sleeve 2 and the conveying assembly 3 to move forward and backward. The moving mechanism 5 includes an electric push rod 51, a pushing base plate 52 and a limiting assembly 53. The electric push rod 51 is fixedly installed inside the bottom bracket 1, the pushing base plate 52 is fixedly installed at the output end of the electric push rod 51, and the limiting assembly 53 is arranged on the upper surface of the pushing base plate 52.

[0047] During use, the electric push rod 51 is started, so that the output end of the electric push rod 51 pushes the pushing base plate 52, and the pushing base plate 52, with the cooperation of the limiting component 53, moves the position of the outer sleeve 2 and the conveying component 3, and adjusts the distance between the outer sleeve 2, the conveying component 3 and the fabric. Subsequently, the conveying component 3 can process the fabric on the side away from itself, further expanding the working range of the equipment itself.

[0048] By the attached Figure 7 As shown, in this embodiment, the limiting assembly 53 also includes a rotating connecting plate 531, a limiting ring 532, a connecting side plate 533 and a fixing member 534. The rotating connecting plate 531 is symmetrically rotatably installed on the top of the pushing base plate 52, the limiting ring 532 is fixedly installed on the top of the rotating connecting plate 531, and the connecting side plate 533 is fixedly installed on the side of the end of the limiting ring 532 away from the rotating connecting plate 531, and a fixing member 534 is arranged inside the connecting side plate 533.

[0049] During use, the outer sleeve 2 is placed on the top of the pushing base plate 52, and then the angle of the limit ring 532 is adjusted by rotating the connecting plate 531. The two sets of limit rings 532 are rotated toward the middle end at the same time to squeeze and clamp the outer wall of the outer sleeve 2 at the middle end. The fixing part 534 is used to fix the distance between the connecting side plates 533 to complete the combination and positioning of the components. The subsequent operation of the electric push rod 51 can drive the outer sleeve 2 and the conveying assembly 3 to move synchronously as a whole.

[0050] By the attached Figure 8 As shown, in this embodiment, the nozzle structure also includes a collecting mechanism 6, which is installed on the side of the pushing base plate 52. The collecting mechanism 6 includes an outer shell 61, a receiving side plate 62, a flow groove 63 and a receiving component 64. The outer shell 61 is arranged at the lower end of the outer sleeve 2, and the receiving side plate 62 is fixedly installed on the side of the outer shell 61. A flow groove 63 is provided at the connection between the receiving side plates 62 and the receiving side plates 62, and a receiving component 64 is arranged inside the outer shell 61.

[0051] During use, when the conveying component 3 is working, due to the characteristics of the textile machine itself, the conveying component 3 is not in operation for a long time. Each time the conveying component 3 sprays, it needs to stop for a certain period of time. When the conveying component 3 stops spraying, some water will automatically fall to the lower end due to the loss of impact force. At this time, the receiving side plate 62 can be used to receive this part of the liquid. Through the inclination of the receiving side plate 62 itself and the opening of the flow groove 63, the liquid is input into the outer shell 61. The receiving component 64 can receive this part of the water source, thereby ensuring the stability of the equipment during operation and reducing the loss of resources.

[0052] By the attached Fig. 9 As shown, in this embodiment, the receiving component 64 also includes a receiving groove 641, a collecting bin 642, a collecting groove 643 and a pulling cover 644. The outer shell 61 is provided with a receiving groove 641, the collecting bin 642 is slidably installed inside the receiving groove 641, a pulling cover 644 is fixedly installed on the side of the collecting bin 642, and a collecting groove 643 is provided inside the collecting bin 642.

[0053] During use, the liquid received by the receiving side plate 62 will automatically enter the receiving groove 641. At this time, the liquid at the upper end is collected by using the collecting bin 642 and all of it is stored in the collecting groove 643, which is convenient for the staff to collect and process quickly. The installation of the pulling cover 644 facilitates the pulling and pulling of the collecting bin 642 as a whole, thereby simplifying the operating steps of the receiving component 64 itself.

[0054] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
