Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, specifically to a water-blocking device for a water jet loom. Background Technology

[0002] A water-jet loom is a shuttleless loom that uses water as a medium and employs jets of water to guide the weft yarn through the shed. Due to the good focusing ability of the water flow and the high frictional pulling force of the water on the weft yarn, the weft speed and loom speed of a water-jet loom are among the highest of all types of looms. A water-jet loom generally includes a body, heald frames, healds, a water jet unit, a reed frame, and a warp beam. Its working principle is as follows: the warp yarn passes through the heald eyelets on the healds from the rear of the loom. The heald frame moves the healds and warp yarns together in a lifting motion to form the shed. Then, the water jet unit sprays water jets, which drives the weft yarn to move and pass through the shed. The reed swings back and forth, beating the weft yarn passing through the shed, thus forming the fabric surface. The reed frame is always located at the edge of the fabric surface to lock the selvage. Because water-jet looms produce a wide variety of fabrics... Due to the diversity of fabrics and the varying weaving widths, when the weaving width is smaller than the maximum weaving width of a water-jet loom, an idle space will appear in the area far from the water jet during weaving. However, the length of the water jet is fixed and will travel the maximum weaving width. At this time, the steel frame moves back and forth, causing the water jet in the idle space to slap towards the rear of the machine. Since there is no obstruction behind the heald frame in the idle space, the water jet will become water droplets splashing onto the machine body and the warp beams behind it, which will cause rust over time. Current technology often involves hanging a plastic curtain behind the machine body in the idle space to block water. However, the plastic curtain in the current technology is fixed and cannot be adjusted according to the different weaving widths of the fabrics, which will result in leakage and inconvenience.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN219824520U discloses a water-jet loom water-blocking device and a water-jet loom, comprising a roller, a water-blocking curtain, and a limiting member. The roller is rotatably connected to the machine body. The water-blocking curtain includes a hook, which is wound around the roller and connected to the movable end of the water-blocking curtain. The hook is used for suspension connection with the ear wire frame. The limiting member is connected to the machine body, and when the hook and ear wire frame are suspended, the limiting member is connected to the roller.

[0004] While the aforementioned existing technical solutions are convenient to use and improve the water-blocking effect, their rollers are directly installed inside the machine body. When the water-blocking curtain becomes damaged or ages, causing a decrease in water-blocking effect, it is difficult for workers to quickly remove the rollers to repair, maintain, or replace the water-blocking curtain, thereby affecting work efficiency.

The structure is simple and the operation is convenient. The movable roller 4 and the water-blocking curtain 5 can be quickly disassembled and assembled by pressing and pulling, which is convenient for personnel to repair or replace, and further improves work efficiency.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the crimping assembly includes two sets of elastic pads 6 installed at the bottom of the movable seat 24. The elastic pads 6 have mounting holes inside. A splicing block 7 is installed on one side of the bottom of the movable seat 24 at the mounting hole on the elastic pad 6. A splicing groove is opened on one side of the top of the fixed seat 3 corresponding to the mounting hole. The splicing groove and the splicing block 7 are slidably connected. The elastic pad 6 is a rubber elastic pad. First, the movable seat 24 is placed on the fixed seat 3, and the elastic pad 6 is pressed down to allow the splicing block 7 to slide into the inner side of the mounting groove along the splicing groove, so that the splicing block 7 and the spring block 11 come into contact and fit together. The two sets of first guide inclined surfaces 13 press against each other, forcing the first limiting block 9 to slide and press the first spring 10 inside the first limiting groove, while stretching the second spring 12.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the fixed base 3 has an installation groove on one side of the splicing groove. A limit seat 8 is installed on one side of the inner wall of the installation groove. A first limit groove is formed on one side of the limit seat 8. A first limit block 9 is slidably connected to the inner side of the first limit groove. A first spring 10 is installed between one side of the first limit block 9 and the inner wall of the first limit groove. A spring block 11 is installed at one end of the first limit block 9. A spring groove is formed on one side of the spring block 11. A second spring 12 is installed between the inner side of the spring groove and the inner wall of the installation groove. The opposite ends of the spring block 11 and the splicing block 7 are provided with mutually fitting first guide slopes 13. A locking groove is formed inside the spring block 11 at its first guide slope 13. A connecting rod 14 is rotatably connected to one end of the inner wall of the locking groove. A locking plate 15 is fitted on the outer side. A torsion spring 16 is installed between one end of the connecting rod 14 and the inner wall of the locking groove. A second guide slope 17 is provided on one side of the locking plate 15. The second guide slope 17 fits into the first guide slope 13. An abutment groove is provided inside the assembly block 7 at its first guide slope 13. Then, the compression continues, causing the first guide slope 13 on the assembly block 7 to press against the second guide slope 17. The locking plate 15 presses the torsion spring 16 back to the inner side of the locking groove until the abutment groove is pushed to the locking groove. Then, the torsion spring 16 drives the locking plate 15 to pop out to the inner side of the abutment groove. At this time, the compression stops, and the elastic pad 6 will rebound a short distance, allowing the inner wall of the abutment groove to abut against one end of the locking plate 15, and quickly locking.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the towing assembly includes a groove on one side of the spring block 11, a movable rod 18 installed on the inner wall of the groove, an extension groove on one side of the outer wall of the fixed seat 3, and a movable groove inside the fixed seat 3 located between the extension groove and the mounting groove. The movable groove and the movable rod 18 are slidably connected. A pull ring 19 is rotatably connected to one end of the movable rod 18 that extends to the inner side of the extension groove. Furthermore, when it is necessary to repair the water curtain 5 or remove it from the movable roller 4 to replace it with a new water curtain 5, simply fasten the pull ring 19 to drive the movable rod 18 to slide inside the movable groove, causing the spring block 11 to retract actively. After the locking plate 15 disengages from the inner side of the abutment groove, the resistance disappears and the elastic pad 6 will fully rebound, causing the abutment groove to move upward. At this time, releasing the pull ring 19 will not reposition it. Then, the movable roller 4 and the water curtain 5 can be removed together for inspection and maintenance.

[0028] In this embodiment, as Figure 1 and Figure 4As shown, the movable hooking mechanism includes a support plate 20 installed on one side of the fixed base 3. The top of the support plate 20 is provided with an adjustment groove. A threaded rod 21 is rotatably connected to the inner side of the adjustment groove. A handle is rotatably connected to one end of the support plate 20. One end of the handle extends to the inner side of the adjustment groove and is fixedly connected to one end of the threaded rod 21. An adjustment plate 22 is threadedly connected to the outer side of the threaded rod 21. The adjustment plate 22 is slidably connected to the adjustment groove. Two sets of hanging rings are installed on one side of the adjustment plate 22. Hooks 23 corresponding to the hanging rings are installed at both ends of one side of the water curtain 5. Furthermore, holding the handle can drive the threaded rod 21 to rotate together, allowing the adjustment plate 22 to slide to a suitable distance inside the adjustment groove. Then, the water curtain 5 is pulled open to hook the two sets of hooks 23 onto the hanging rings.

[0029] The implementation principle of the water-blocking device for a water-jet loom according to this application embodiment is as follows: The movable seat 24 is placed on the fixed seat 3, and the elastic pad 6 is pressed down, allowing the splicing block 7 to slide into the inner side of the mounting groove along the splicing groove, so that the splicing block 7 and the spring-loaded block 11 come into contact and fit together. The two sets of first guide inclined surfaces 13 press against each other, forcing the first limiting block 9 to slide and press the first spring 10 inside the first limiting groove, while stretching the second spring 12. The pressing continues, causing the first guide inclined surface 13 on the splicing block 7 to press against the second guide inclined surface 17. The locking plate 15 presses the torsion spring 16 back to the inner side of the locking groove until the abutment groove is pushed to the locking groove. Then, the torsion spring 16 drives the locking plate 15 to pop out to the inner side of the abutment groove. At this time, the pressing is no longer performed, and the elastic pad 6 will return. After a short distance, allow the inner wall of the contact groove to abut against one end of the locking plate 15 and quickly lock it in place. When the water curtain 5 needs to be repaired or removed from the movable roller 4 to replace it with a new one, simply hold the pull ring 19 to drive the movable rod 18 to slide inside the movable groove, causing the spring block 11 to retract actively. After the locking plate 15 is removed from the inner side of the contact groove, the resistance disappears and the elastic pad 6 will fully rebound, causing the contact groove to move upward. At this time, releasing the pull ring 19 will not reposition it. Then, the movable roller 4 and the water curtain 5 can be removed together for inspection and maintenance. Holding the handle can drive the threaded rod 21 to rotate together, allowing the adjusting plate 22 to slide to a suitable distance inside the adjusting groove. Then, pull open the water curtain 5 and hang the two sets of hooks 23 on the hanging ring.
