Description

Technical Field

[0001] This invention relates to the field of pressurization technology for water jet looms, and in particular to a built-in pressurization guide column for use in water jet looms. Background Technology

[0002] Water jet looms use jets of water to create frictional traction on the weft yarn, guiding it 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 than air-jet weft introduction, with less diffusion, making it suitable for smooth synthetic fibers. Simultaneously, water jet looms effectively eliminate the effects of static electricity from synthetic fibers on weaving, making them ideal for weaving synthetic filaments, especially hydrophobic filaments like polyester. However, when weaving larger fabrics or when multiple looms are running simultaneously, the water pressure on one side cannot guarantee stable water flow over a long distance. Therefore, internal relay devices are needed to enhance water flow pressure. Traditional relay devices are simple in structure, achieving water flow stability simply by filling with liquid to increase pressure. However, their pressure can only be provided by external replenishment fluid, and the hydraulic pressure varies at different locations, making it impossible to ensure consistent pressure across all relay devices or automatically adjust the pressure according to changes in water flow pressure at different locations. This results in limited functionality and intelligence. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the traditional relay device 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 is inconsistent at different locations, 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 locations, resulting in relatively simple functionality and intelligence.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a built-in pressure boosting guide column applied to a water jet loom, including a lateral fixing frame installed on the inner wall of the water jet loom and an external water supply pipe installed inside the lateral fixing frame. A lateral guide pipe is assembled on the side wall of the lateral fixing frame. An internal flow collector is fixedly assembled inside the lateral guide pipe. An external transmission cover with an outwardly protruding integral structure is provided on the outer side surface of the lateral guide pipe. A combined pressure boosting component is movably assembled inside the external transmission cover. An internal diffuser hole is opened inside the internal flow collector corresponding to the position of the combined pressure boosting component.

[0005] The combined booster assembly includes a drive stator fixedly mounted on the inner side of the internal manifold, a drive rotor located inside the drive stator, and combined liquid-guiding booster blades fixedly mounted on the inner wall of the drive rotor.

[0006] The combined liquid-guiding and pressurizing blade includes a closed cover fixed on the inner side of the drive rotor, a pressurizing blade fixed on the inner side of the closed cover, a centrifugal extraction blade, and an internal fixing frame fixed between the pressurizing blade and the centrifugal extraction blade.

[0007] The opening inside the internal flow collector gradually decreases in size from the inlet to the outlet.

[0008] The inner surface of the side-mounted guide tube has a spiral-shaped internal flow guiding surface.

[0009] An external connector with a built-in solenoid valve is fixedly mounted on the outer wall of the side-mounted guide pipe, and the outer end of the external water supply pipe is fixedly connected to the inside of the side-mounted guide pipe by being sleeved on the outside of the external connector.

[0010] A plurality of embedded pressure monitoring strips are fixedly mounted on the inner side of the internal flow collector.

[0011] The inner surface of the internal diffuser hole has an obliquely placed flow guide.

[0012] An infrared monitoring module for detecting water flow distance is fixedly installed on the inner side of the internal flow collector at the opening position.

[0013] The lateral fixing frame includes a fixed bracket fixed to the inner wall of the water jet loom and an external adjusting frame bolted to the outside of the fixed bracket.

[0014] The beneficial effects of this invention are:

[0015] (1) The built-in pressure boosting guide column of the present invention applied to a water jet loom can extract the internal scattered flow and repressurize and concentrate it by adopting a built-in flow guiding device, thereby enhancing the pressure of the internal through water flow.

[0016] (2) By installing an internal flow collection hood, internal infrared monitoring equipment and pressure monitoring equipment can be installed, thereby monitoring the internal water flow in real time, facilitating automatic control, and also improving guidance.

[0017] (3) The combined liquid guiding and pressurizing blades can draw the diffused flow from the internal flow collection hood, and then use the internal pressurization to quickly fill back the internal through water flow. The water flow can also be supplemented by the external water supply pipe as needed, thereby ensuring water pressure consistency.

[0018] (4) The combined liquid guiding and pressurizing blades adopt the method of internal centrifugal extraction and then transverse driving, which can guide the air and greatly enhance the guiding effect.

[0019] (5) The internal flow guide surface of the spiral structure located on the inner side of the side guide tube can improve the stability of pressurized air and water flow;

[0020] (6) By adopting a double-layer structure design, flow can be guided and pressurized at different locations without affecting each other, thus improving stability. Attached Figure Description

[0025] 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.

[0026] 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.

[0027] Figure 1 , Figure 2 and Figure 3 The illustrated built-in pressure boosting guide column for a water jet loom includes a lateral fixing frame 1 installed on the inner wall of the water jet loom and an external water supply pipe 2 installed inside the lateral fixing frame 1. A lateral guide pipe 3 is mounted on the side wall of the lateral fixing frame 1. An internal flow collector 4 is fixedly mounted inside the lateral guide pipe 3. An external transmission cover 5 with an outwardly protruding integral structure is provided on the outer side surface of the lateral guide pipe 3. A combined pressure boosting component 6 is movably mounted inside the external transmission cover 5. An internal diffuser hole 7 is provided inside the internal flow collector 4 at the position corresponding to the combined pressure boosting component 6.

[0028] High-pressure water flows horizontally through the internal collection shroud 4 to form an internal through-flow. During the flow, it will generate a diffuse flow. The diffuse flow is then processed by the combined pressurization component 6, which draws air into the space between the internal collection shroud 4 and the side guide pipe 3. After being repressurized, the air flows from the right outlet of the side guide pipe 3 to converge with the internal through-flow, thus forming a high-pressure water column again.

[0029] To facilitate the drive, the combined booster assembly 6 includes a drive stator 8 fixedly mounted on the inner side of the internal manifold 4, a drive rotor 9 located inside the drive stator 8, and a combined liquid-guiding booster blade 10 fixedly mounted on the inner wall of the drive rotor 9.

[0030] The drive stator 8 and drive rotor 9 form a structure similar to a ring motor. The drive rotor 9 is controlled to rotate at high speed by generating magnetism through the windings on the drive stator 8.

[0031] To facilitate airflow, the combined liquid-guiding booster blade 10 includes a closed cover 101 fixed on the inner side of the drive rotor 9, a booster blade 102 fixed on the inner side of the closed cover 101, a centrifugal extraction blade 103, and an internal fixing frame 104 fixed between the booster blade 102 and the centrifugal extraction blade 103.

[0032] The waterproofness of the interior of the external transmission housing 5 is ensured by closing the housing 101.

[0033] To improve the internal flow guidance and pressurization effect, the internal opening of the internal flow collector 4 gradually decreases from the inlet to the outlet.

[0034] To improve the pressurization effect and guide distance, the inner side of the side guide tube 3 has a spiral structure internal guide surface.

[0035] To facilitate external liquid supply, an external connector 11 with a built-in solenoid valve is fixedly mounted on the outer wall of the side-mounted guide pipe 3. The outer end of the external water supply pipe 2 is fixedly connected to the inside of the side-mounted guide pipe 3 by being sleeved on the outside of the external connector 11.

[0036] In order to monitor the pressure and location of the internal through-flow water, three embedded pressure monitoring strips 12 are fixedly installed on the inner side of the internal flow collector 4.

[0037] The pressure monitoring strip 12 is mainly installed on one side of the inner bottom surface. When the water pressure decreases, the diffused water will hit the pressure monitoring strip 12, thereby judging the change in water pressure. When the diffused pressure increases, it means that the water pressure is decreasing, and the speed of the combined booster assembly 6 needs to be increased.

[0038] In order to avoid affecting the flow direction of the internal through-flow water, the inner surface of the internal diffuser hole 7 has an inclined guide shroud 13.

[0039] In order to facilitate the monitoring of the internal flow of water, an infrared monitoring module 14 for detecting the distance of water flow is fixedly installed on the inner side of the internal flow collector 4 at the opening position.

[0040] The infrared monitoring module 14 is fixed on the inner side of the internal flow collector 4 in a ring array and then monitors the incoming water flow. When water flow is detected, the pressure monitoring bar 12 is automatically activated. Then, based on the changes in water flow pressure and flow dispersion pressure of the pressure monitoring bar 12, the combined pressurization component 6 and the solenoid valve are automatically activated, and the rotation speed of the combined pressurization component 6 is adjusted.

[0041] To improve applicability, the lateral fixing frame 1 includes a fixing bracket fixed to the inner wall of the water jet loom and an external adjusting frame bolted to the outside of the fixing bracket.

[0042] The side guide tube 3 is fixed to the outside of the external adjustment frame. A side locking bolt is threaded on the outside of the external adjustment frame. By tightening the side locking bolt inward, the external adjustment frame and the fixed bracket can be fixedly assembled.

[0043] 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.
