Description

Technical Field

[0001] This invention relates to the field of water jet loom nozzle technology, and in particular to a telescopic relay nozzle for water jet looms. Background Technology

[0002] Water jet looms use jets of water to generate frictional traction on the weft yarn, controlling its introduction into the shed. Utilizing water as the weft-introducing medium, the water jet pulls the weft yarn through the shed. This method provides greater frictional traction on the weft yarn than air-jet weft introduction, with less diffusion, making it suitable for smooth-surfaced synthetic fibers.

[0003] However, when weaving large-sized fabrics or when multiple looms are running simultaneously, the water pressure on one side cannot guarantee the water flow required for a long stroke, resulting in low stability. Therefore, it is necessary to install an internal relay device to enhance the water flow pressure. Traditional relay devices have a simple structure and simply achieve water flow stability by filling and pressurizing with liquid. However, the pressure can only be provided by external replenishment liquid. The hydraulic pressure at different locations is inconsistent, making it impossible to guarantee that the pressure of each relay device is consistent, and it is also impossible to automatically adjust the pressure according to the changes in water flow pressure at different locations. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the relay device used in traditional water jet looms has a simple structure and simply achieves water flow stability by filling and pressurizing. However, its pressure can only be provided by external replenishment fluid. However, the hydraulic pressure at different positions is inconsistent, which makes it impossible to ensure that the pressure of each relay device is consistent, and it is also impossible to automatically adjust the pressure according to the changes in water flow pressure at different positions.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a telescopic relay nozzle for a water jet loom, including a main frame of the water jet loom, an inner flip groove is provided on the inner side of the main frame of the water jet loom, an electrically controlled flip adjustment frame is movably assembled inside the inner flip groove, an outer electrically controlled nozzle is movably assembled outside the electrically controlled flip adjustment frame, an inner pressure boosting hood is fixedly assembled inside the electrically controlled flip adjustment frame, an internal pressure boosting pump is installed inside the internal pressure boosting hood, one side inlet of the outer electrically controlled nozzle is connected to the external inlet of the internal pressure boosting hood, and the other side outlet of the outer electrically controlled nozzle is fixedly connected to the inside of the internal pressure boosting hood through an external drain pipe.

[0006] The electrically controlled flip adjustment frame includes a flip frame that is movably installed in the inner flip groove via two side pivots and a flip support rod that is movably assembled inside the inner flip groove. The top of the telescopic section of the flip support rod is movably assembled with the inner side of the flip frame.

[0007] Lateral telescopic blind holes are provided at both ends of the outer side of the flipping frame. The outer electronically controlled nozzle includes an internal support rod fixed inside the lateral telescopic blind hole, an external telescopic shaft fixed axially to the telescopic end of the internal support rod, and a horizontally placed guide nozzle fixed to the outside of the external telescopic shaft.

[0008] The horizontally positioned guide nozzle has an internal limiting frame with an electromagnet fixedly mounted at its center. The horizontally positioned guide nozzle also has an internally closed water guide seat that slides inside. An iron spring is installed between the internally closed water guide seat and the internal limiting frame.

[0009] The outer side of the horizontally positioned guide nozzle is fixedly connected to the inside of the internal pressure shroud via a lateral liquid inlet pipe, and an internal guide port connected to the lateral liquid inlet pipe is provided on the inner wall of the horizontally positioned guide nozzle.

[0010] The water-facing surface of the internal closed water guide seat is an arc-shaped guide surface that matches the internal guide port.

[0011] An embedded pressure sensor controller and an embedded humidity sensor controller are installed on the arc-shaped guide surface.

[0012] The outer side of the horizontally positioned guide nozzle has an outwardly protruding outer filter cover at the end fixedly connected to the lateral liquid inlet pipe. A detachable internal filter screen is installed inside the outer filter cover, and an external loading and unloading port for installing the detachable internal filter screen is provided on the outer side of the outer filter cover.

[0013] A lateral limiting lock groove is provided on the inner side of the external loading and unloading port, and an external control groove is provided on the outer side of the detachable internal filter screen. An external rotating lock that cooperates with the lateral limiting lock groove is movably fitted inside the external control groove.

[0014] The liquid outlet end of the horizontally positioned guide nozzle is movably equipped with a universal ball guide nozzle.

[0015] The beneficial effects of this invention are:

[0016] (1) The telescopic relay nozzle for water jet loom of the present invention adopts a flip-up design, which can be stored in the inner flip-up groove when not in use, which greatly improves the safety of its storage.

[0017] (2) By adopting a flip-up and telescopic design, the adjustable range of the horizontal guide nozzle can be greatly improved, making it more applicable;

[0018] (3) An internal closed water guide seat controlled by an electromagnet is provided inside the horizontally positioned guide nozzle. The internal closed water guide seat can be used to close the water inlet on the outside of the horizontally positioned guide nozzle, thereby improving internal isolation and durability.

[0019] (4) By using the embedded pressure sensor controller and the embedded humidity sensor controller located on the water-facing surface of the internal closed water guide seat, the electromagnet and the internal booster pump can be automatically controlled according to the pressure and humidity of the water-facing surface.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Figure 1 , Figure 2 and Figure 3The telescopic relay nozzle shown includes a water jet loom main frame 1. An inner flip groove 2 is provided on the inner side of the water jet loom main frame 1. An electrically controlled flip adjustment frame 3 is movably installed inside the inner flip groove 2. An outer electrically controlled nozzle 4 is movably installed outside the electrically controlled flip adjustment frame 3. An internal pressure boosting cover 5 is fixedly installed inside the electrically controlled flip adjustment frame 3. An internal pressure boosting pump 7 is installed inside the internal pressure boosting cover 5. One side liquid inlet of the outer electrically controlled nozzle 4 is connected to the external liquid inlet of the internal pressure boosting cover 5. The other side liquid outlet of the outer electrically controlled nozzle 4 is fixedly connected to the internal pressure boosting cover 5 through an external drain pipe 8.

[0029] An external liquid supply pipe is also installed on the internal pressure boosting hood 5 to ensure consistent pressure at the outlet. A solenoid valve is installed at the connection end of the external liquid supply pipe. A pressure monitoring module is installed at the outlet on the outside of the internal pressure boosting hood 5. When the external liquid supply pipe starts supplying liquid, if the pressure monitoring module cannot reach the set value after the external liquid supply pipe supplies liquid, the speed of the internal pressure boosting pump 7 will be increased. When the external liquid supply pipe supplies liquid and the pressure monitoring module reaches the set value, the speed of the internal pressure boosting pump 7 will be reduced.

[0030] To facilitate the tilt adjustment control, the electronically controlled tilt adjustment frame 3 includes a tilt frame 31 that is movably installed in the inner tilt groove 2 via two side pivots and a tilt support rod 32 that is movably assembled inside the inner tilt groove 2. The top of the telescopic section of the tilt support rod 32 is movably assembled with the inner side of the tilt frame 31.

[0031] The flipping strut 32 is existing technology, and the flipping frame 31 is flipped by telescoping.

[0032] To facilitate telescopic adjustment, both ends of the outer side of the flip frame 31 are provided with lateral telescopic blind holes. The outer electric control nozzle 4 includes an internal support rod 41 fixed inside the lateral telescopic blind hole, an external telescopic shaft 42 axially fixed to the telescopic end of the internal support rod 41, and a horizontal guide nozzle 43 fixed to the outside of the external telescopic shaft 42.

[0033] The built-in support rod 41 extends and retracts to drive the external telescopic shaft 42 to extend and retract within the lateral telescopic blind hole, thereby changing the telescopic adjustment of the horizontal guide nozzle 43. By utilizing the angle adjustment of the flip frame 31 and the telescopic adjustment of the external telescopic shaft 42, the position of the horizontal guide nozzle 43 can be changed within a wide range.

[0034] To facilitate electromagnetic control, an internal limiting frame 45 with an internal electromagnet 44 is fixedly mounted at the center of the horizontally positioned guide nozzle 43. An internal closed water guide seat 46 is slidably mounted inside the horizontally positioned guide nozzle 43, and an iron spring 47 is installed between the internal closed water guide seat 46 and the internal limiting frame 45.

[0035] The electromagnet 44 controls the contraction of the iron spring 47 by being energized, and the iron spring 47 controls the sliding adjustment of the internal closed water guide seat 46.

[0036] To facilitate lateral liquid guidance, the outer side of the horizontally positioned guide nozzle 43 is fixedly connected to the interior of the internal pressurization shroud 5 via a lateral liquid inlet pipe 48, and an internal guide port 49 connected to the lateral liquid inlet pipe 48 is provided on the inner wall of the horizontally positioned guide nozzle 43.

[0037] To reduce the resistance at the inlet end, the water-facing surface of the internal closed water guide seat 46 is an arc-shaped guide surface that matches the internal guide port 49.

[0038] To facilitate monitoring of the water-facing surface, an embedded pressure sensor controller 9 and an embedded humidity sensor controller 10 are installed on the arc-shaped guide surface.

[0039] The embedded pressure sensor controller 9 and the embedded humidity sensor controller 10 are existing technologies. When the liquid from the inlet is introduced into the horizontal guide nozzle 43, the liquid will impact the embedded pressure sensor controller 9 and the embedded humidity sensor controller 10. At this time, the embedded humidity sensor controller 10 will activate the electromagnet 44, and then the embedded pressure sensor controller 9 will activate the internal booster pump 7. The internal booster pump 7 starts to rotate and guides the sprayed liquid through the internal guide port 49 into the side liquid inlet pipe 48, and then draws it into the internal booster shroud 5. Then the internal booster pump 7 inside the internal booster shroud 5 discharges the liquid into the liquid inlet on one side of the outer electronically controlled nozzle 4 through the external drain pipe 8.

[0040] When there is no liquid inlet at the horizontal guide nozzle 43, the embedded pressure sensor controller 9 does not monitor the pressure, and then the humidity of the embedded humidity sensor controller 10 drops rapidly. At this time, the electromagnet 44 and the internal booster pump 7 are turned off.

[0041] To facilitate the filtration of the incoming liquid and for easy and quick disassembly and replacement, the outer side of the horizontal guide nozzle 43 has an outwardly protruding outer filter cover 11 at the end fixedly connected to the side inlet pipe 48. A removable internal filter screen 12 is installed inside the outer filter cover 11, and an external loading and unloading port for installing the removable internal filter screen 12 is provided on the outer side of the outer filter cover 11.

[0042] To facilitate rapid loading and unloading, a lateral limiting lock groove 13 is provided on the inner side of the external loading and unloading port, and an external control groove is provided on the outer side of the detachable internal filter screen 12. An external rotating lock 14 that cooperates with the lateral limiting lock groove 13 is movably fitted inside the external control groove.

[0043] The external rotating latch 14, by rotating, inserts into the lateral limiting lock groove 13 through the locking blocks on both sides, thus fixing the detachable internal filter screen 12 inside the external loading and unloading port.

[0044] In order to adjust the lateral liquid discharge angle of the horizontally positioned guide nozzle 43, a universal ball guide nozzle 15 is movably mounted at the liquid discharge end of the horizontally positioned guide nozzle 43.

[0045] An arc-shaped assembly groove is provided on the inner wall of the liquid outlet end on the outer side of the horizontal guide nozzle 43. The universal ball guide nozzle 15 is inserted into the arc-shaped assembly groove through an integral universal ball connector and is movably assembled with the horizontal guide nozzle 43. The angle of the universal ball guide nozzle 15 is fixed by the locking bolt on the outer side of the horizontal guide nozzle 43.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
