Abstract
Description
Technical Field
[0001] This utility model relates to a stable water jet loom for textile fabrics, belonging to the field of textile equipment. Background Technology
[0002] Water jet looms are a common type of textile equipment. They consist of a motor, nozzles, a water jet device, a control system, and a weaving mechanism. Their principle is to use a high-speed jet of water from the nozzle to draw out the weft yarns, which then interweave with the warp yarns, thus achieving high-speed weaving. However, existing water jet looms have shortcomings. Their water jet device relies on the spring force to apply force to a piston, pushing the piston to eject the water jet. Since the spring force is directly proportional to the spring deformation, initially, the spring deformation is at its maximum, resulting in the maximum spring force and the maximum force exerted by the piston on the water jet. This effect only decreases when the deformation reduces to zero, at which point the spring force and the force exerted by the piston on the water jet become zero. Therefore, the effect of the water jet on drawing out the weft yarns is not constant. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a stable water jet loom for textile fabrics, so as to achieve a constant water jet effect on the weft yarn.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a stable water-jet loom for textile fabrics, comprising a water-jet device, wherein the water-jet device includes a first pressure cylinder, an air pipe, a first piston, a push rod, a first lever, a second lever, a third lever, a rotating shaft, a cam, a drive shaft, a first pressure cylinder, a first hinge, a second hinge, a lower water pipe, an upper water pipe, a first one-way valve, a second one-way valve, a mounting base, a second piston, a second pressure cylinder, a cover, and a pull rod. One end of the lower water pipe is connected to the bottom end of the second pressure cylinder through the first one-way valve, and one end of the upper water pipe is connected to the bottom end of the second pressure cylinder through the second one-way valve. The other end of the upper water pipe is screwed to the mounting base; the cover... The cover is fitted onto the top of the second pressure cylinder; a pull rod passes through the cover and moves up and down within it, with the bottom end of the pull rod connected to the second piston; a rotating shaft is rotatably connected to the frame, and a first lever, a second lever, and a third lever are connected to the rotating shaft; the end of the first lever is connected to the top of the pull rod via a second hinge; the end of the second lever is connected to a roller, which meshes with a cam, the center of which is connected to the drive shaft; the end of the third lever is connected to one end of a push rod via a first hinge, the push rod passes through the first pressure cylinder and moves back and forth within it, with the end of the push rod connected to the first piston; an air pipe is connected to the right end of the first pressure cylinder, and the air pipe and the push rod are respectively located on both sides of the first piston.
[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: The cam is driven to rotate by a drive shaft. The cam, through a roller, pushes the second lever to rotate around the rotation axis, causing the first lever to rotate accordingly. The first lever, through a second hinge, drives the pull rod to rise. The pull rod drives the second piston to rise, creating a negative pressure in the second pressure cylinder. At this time, the second one-way valve closes, the first one-way valve opens, and water enters the bottom of the second pressure cylinder through the drain pipe and the first one-way valve, completing the water suction step.
[0006] High-pressure air is injected into the first pressure cylinder through an air pipe, pushing the first piston and push rod to move. The push rod, through the first hinge, pushes the third lever to rotate around the rotation axis, causing the first lever to rotate accordingly. The first lever, through the second hinge, drives the guide cylinder to descend. The guide cylinder drives the second piston to descend, creating positive pressure in the second pressure cylinder. The first one-way valve closes, and the second one-way valve opens, pushing water in the second pressure cylinder from the second one-way valve and the water inlet pipe to the mounting base. This completes the water jet ejection step. Because the high-pressure gas pressure delivered from the air pipe to the first pressure cylinder is constant, the thrust transmitted to the second piston is constant, ensuring a stable and consistent force is applied to the water jet. The water jet's effect on drawing out the latitude line is constant. By alternating between the water intake and water jet ejection steps, the latitude line is intermittently driven to move.

One end of the lower water pipe 14 is connected to the bottom end of the second pressure cylinder 22 through the first one-way valve 16, and one end of the upper water pipe 15 is connected to the bottom end of the second pressure cylinder 22 through the second one-way valve 17. The other end of the upper water pipe 15 is screwed to the mounting base 20. The cover 23 covers the first piston 1, the second piston 21, the second pressure cylinder 22, the second piston 22, the third piston 23, and the fourth piston 24. The top of the second pressure cylinder 22; the pull rod 26 passes through the cover 23 and moves up and down in the cover 23, the bottom end of the pull rod 26 is connected to the second piston 21; the rotating shaft 8 is rotatably connected to the frame, and the rotating shaft 8 is connected to the first lever 5, the second lever 6 and the third lever 7. The end of the first lever 5 is connected to the top of the pull rod 26 through the second hinge 13; the end of the second lever 6 is connected to the roller 11, the roller 11 is engaged with the cam 9, and the center of the cam 9 is connected to the drive shaft 10; the end of the third lever 7 is connected to one end of the push rod 4 through the first hinge 12, the push rod 4 passes through the first pressure cylinder 1 and moves back and forth in the first pressure cylinder 1, the end of the push rod 4 is connected to the first piston 3; the right end of the first pressure cylinder 1 is connected to the air pipe 2, and the air pipe 2 and the push rod 4 are respectively set on both sides of the first piston 3.
[0012] The second hinge 13 is a dual-axis hinge. The first lever 5, the second lever 6, and the third lever 7 are of equal length and are connected in a circular array in the radial direction of the rotating shaft 8. The cover 23 is provided with air holes 24. The end of the drain pipe 14 is connected to a filter cover 19, which is inserted into the water tank 18. A guide cylinder 25 is connected to the cover 23, and the pull rod 26 passes through the guide cylinder 25 and moves up and down within the guide cylinder 25.
[0013] In summary, the method of using the stable water-jet loom for textile fabrics shown in this utility model is as follows: A motor (not shown) drives a cam 9 to rotate via a drive shaft 10. The cam 9, through a roller 11, pushes a second lever 6 to rotate around a rotating shaft 8, causing the first lever 5 to rotate accordingly. The first lever 5, through a second hinge 13, drives a pull rod 26 to rise. The pull rod 26 drives a second piston 21 to rise, creating a negative pressure in the second pressure cylinder 22. At this time, the second one-way valve 17 closes, and the first one-way valve 16 opens. Water enters the bottom of the second pressure cylinder 22 through the drain pipe 14 and the first one-way valve 16, completing the water absorption step.
[0014] High-pressure air is injected into the first pressure cylinder 1 through the air pipe 2, pushing the first piston 3 and push rod 4 to move. Push rod 4 pushes the third lever 7 to rotate around the rotation axis 8 through the first hinge 12, causing the first lever 5 to rotate accordingly. The first lever 5 drives the guide cylinder 25 to descend through the second hinge 13. The guide cylinder 25 drives the second piston 21 to descend, creating positive pressure in the second pressure cylinder 22. The first one-way valve 16 closes, and the second one-way valve 17 opens, pushing the water in the second pressure cylinder 22 to flow from the second one-way valve 17 and the water inlet pipe 15 to the mounting base 20. This completes the water jet ejection step. Because the high-pressure gas pressure delivered from the air pipe 2 to the first pressure cylinder 1 is constant, the thrust transmitted to the second piston 21 is constant, ensuring a stable application of the same force to the water jet. The water jet's effect on the latitude line is constant. By alternating between the water intake and water jet ejection steps, the latitude line is intermittently driven to move. The air hole 24 maintains the upper part of the second pressure cylinder 22 at atmospheric pressure. The filter cover 19 prevents solid impurities from entering the drain pipe 14. The guide cylinder 25 guides the pull rod 26 and the second piston 21 to move vertically together, avoiding increased friction between the second piston 21 and the inner wall of the second pressure cylinder 22 due to the tilting of the pull rod 26.
