Description

Technical Field

[0001] This invention relates to the field of water jet loom technology, specifically to a high-efficiency water squeezing mechanism for water jet looms. Background Technology

[0002] Water jet looms are shuttleless looms that use jets of water to guide the weft yarn through the shed. Water jet weft insertion exerts a greater frictional pulling force on the weft yarn than air jet weft insertion, with less diffusion, making it suitable for weft insertion of smooth-surfaced synthetic fibers, glass fibers, and other filaments. It also increases the electrical conductivity of synthetic fibers, effectively overcoming static electricity during weaving.

[0003] In the existing technology, the water jet loom mainly relies on nozzles in conjunction with the pump to spray water jets to pull the weft yarn. However, due to impurities in the water, the nozzles will become clogged after a certain period of use, and then need to be unblocked or replaced as needed.

[0004] However, replacing a typical nozzle body is difficult and requires disassembling multiple parts, which leads to a significant time consumption and impacts production efficiency.

[0005] Therefore, this invention proposes a high-efficiency water-squeezing mechanism for water-jet looms to solve the above problems. Summary of the Invention

After cleaning, the sealing plate seals the chip discharge port, allowing the nozzle body to continue spraying water conveniently. This avoids the problem of conventional nozzle bodies being difficult to replace, requiring the disassembly of multiple parts, which leads to excessive time consumption and reduced production efficiency.

[0023] Please see Figures 1 to 8 This invention provides a technical solution: a high-efficiency water-squeezing mechanism for a water-jet loom, comprising: a nozzle body 1, a sealed bearing 2 at one end of the nozzle body 1, a second nut 3 on the surface of the sealed bearing 2, a sealed screw tube 4 on the surface of the second nut 3, a base 5 inside the nozzle body 1, a filter screen 6 on the surface of the base 5, a chip discharge port 7 at the bottom of the nozzle body 1, a sealing plate 8 inside the chip discharge port 7; a second sealing plate 9, a support rod 10 inside the second sealing plate 9, a base plate 11 at one end of the support rod 10, a cleaning plate 12 on the surface of the base plate 11, and a cleaning brush 13 on the side of the cleaning plate 12; The water sprayed from the nozzle body 1 can be used to pull the weft yarn.

Two sets of fixing plates 24 are provided, and the two sets of fixing plates 24 are symmetrically distributed about the support rod 10. In use, the fixing plate 24 can be sleeved on the screw 14, and then the mounting nut 25 can be rotated to make the bottom of the second sealing plate 9 snap into the placement groove 19. The second sealing plate 9, together with the sealing gasket 20, can seal the through hole 17 to prevent water from flowing out of the through hole 17. The fixing screw 15 and the fixing nut 16 are used to make the sealing plate 8 seal the chip discharge port 7 below the nozzle body 1. When the inside of the nozzle body 1 is blocked by large impurities, the second nut 3 can be directly rotated to make the second nut 3, together with the sealing bearing 2, remove the sealing screw tube 4 from the water jet loom, so that the large impurities inside the nozzle body 1 can be poured out more conveniently. Example 3

[0025] Based on Embodiment 2, a cleaning plate 12 is provided to facilitate the cleaning of impurities inside the nozzle body 1. A through hole 17 is provided on the upper surface of the nozzle body 1, and a positioning frame 18 is provided around the through hole 17. A placement groove 19 is provided on the surface of the positioning frame 18, and a sealing gasket 20 is provided in the placement groove 19. The sealing gasket 20 is glued in the placement groove 19 and has a square frame structure.

The cleaning brush 13 provided on the side of the cleaning plate 12 can clean the surface of the filter screen 6. The sealing plate 8 has an arc-shaped plate structure. A second fixing plate 26 is provided on the side of the sealing plate 8. A second hole is opened on the surface of the second fixing plate 26. The second fixing plate 26 can be sleeved on the fixing screw 15 through the second hole opened on the surface. A second sealing groove 27 is opened on the side of the sealing plate 8. A sealing ring 28 is provided in the second sealing groove 27. The sealing ring 28 is glued in the second sealing groove 27. The sealing ring 28 is arranged around the sealing plate 8. A support spring 29 is sleeved on the surface of the support rod 10. One end of the support spring 29 is fixedly connected to the inner ring surface of the second sealing plate 9. The other end of the support spring 29 is fixedly connected to the surface of the base plate 11. When cleaning the surface of the filter screen 6 is required during use, the positioning nut 23 can be rotated first so that the positioning nut 23, in conjunction with the bearing 22, can move the support rod 10 downward. When the positioning nut 23 disengages from the thread on the surface of the support rod 10, the support rod 10 can be moved up and down repeatedly. The cleaning brush 13 provided on the side of the cleaning plate 12 can be used to clean the filter screen 6, and impurities can fall out from the chip discharge port 7. The cleaning brush 13 has hard bristles and can be inserted into the filter holes of the filter screen 6 for easy cleaning. The support spring 29 provides support for the support rod 10. The sealing ring 28 provided on the side of the sealing plate 8 can improve the sealing of the sealing plate 8 to the chip discharge port 7 and prevent leakage.

[0026] Working principle: In actual use, the water sprayed from the nozzle body 1 can be used to pull the weft yarn. When the nozzle body 1 becomes clogged after prolonged use, the positioning nut 23 can be rotated to move the support rod 10 downwards, and then the fixing nut 16 can be rotated to disengage the sealing plate 8 from the chip discharge port 7. Then, the support rod 10 can be pushed up and down repeatedly, and the cleaning plate 12 at one end of the support rod 10 can be used in conjunction with the cleaning brush 13 to clean the surface of the filter screen 6. After cleaning, the sealing plate 8 can be used to seal the chip discharge port 7, so that the nozzle body 1 can continue to spray water. This is more convenient and avoids the problem that it is difficult to replace a general nozzle body 1 when it becomes clogged, which requires disassembling multiple parts and thus consumes a lot of time and affects production efficiency.
