Description

Technical Field

[0001] The utility model relates to the technical field of water jet looms, in particular to a nozzle for a water jet loom. Background Art

[0002] A water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shed. Compared to air jet weft insertion, water jet weft insertion creates greater frictional traction on the weft yarn and reduces diffusion, making it ideal for inserting smooth-surfaced filaments such as synthetic and glass fibers. It also increases the conductivity of synthetic fibers, effectively combating static electricity during weaving. Furthermore, water jet weft insertion consumes less energy and minimizes noise.

[0003] The water sources used in existing water jet looms are generally not pure enough, and the nozzles used generally do not have a filtering function. When using water containing impurities for weaving, the floating objects in the water will cause the nozzles of the water jet loom to be blocked, and the nozzles need to be replaced frequently, which increases the cost of use. At the same time, water containing impurities will also affect the operating efficiency of the loom and the quality of its components and fabrics. Therefore, it is particularly important to improve the existing nozzles and design a new type of nozzle for water jet looms to solve the above technical defects and improve the practicality of the overall nozzle.

DETAILED DESCRIPTION

[0022] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A nozzle for a water jet loom includes a nozzle body 1. A first connecting shell 2 is provided on the outside of the nozzle body 1, and a connecting shaft 3 is provided inside the nozzle body 1. A second connecting shell 4 is threadedly connected to the outside of the first connecting shell 2. A filter cartridge 5 is provided inside the second connecting shell 4. The filter cartridge 5 is connected to the connecting shaft 3 via a connecting assembly 6. A third connecting shell 7 is provided at the end of the connecting shaft 3 away from the second connecting shell 4. The third connecting shell 7 is threadedly connected to the second connecting shell 4.

[0026] The connecting assembly 6 is used for quick connection between the filter cartridge 5 and the connecting shaft 3 .

[0027] Furthermore, the connecting assembly 6 is composed of a sleeve 8, a moving rod 9, a moving block 10, a connecting rod 11 and a clamping block 12. Multiple groups of sleeves 8 are located inside the filter cylinder 5, the moving rod 9 is slidably connected to the inside of the sleeve 8, the moving block 10 is located at the end of the moving rod 9 extending to the outside of the sleeve 8, the connecting rod 11 is fixedly connected to the end of the moving block 10 away from the moving rod 9, and the clamping block 12 is fixedly connected to the end of the connecting rod 11 away from the moving block 10. When the nozzle body 1 is in use, the filter cylinder 5 is installed on the outside of the connecting shaft 3 through the connecting assembly 6, so that the filter cylinder 5 can be connected to the nozzle body 1. The water flow introduced into the nozzle body 1 can be filtered through the filter cylinder 5 to prevent impurities carried by the water flow from adhering to the inside of the nozzle body 1, causing the nozzle body 1 to be blocked, affecting use, and no frequent nozzle replacement is required, which greatly reduces the user's usage cost. Water can also be filtered to prevent water containing impurities from affecting the operating efficiency, components and fabric quality of the loom.

[0028] Among them, a guide groove 13 is opened inside the moving block 10, and the internal structure size of the guide groove 13 is designed to correspond to the external structure size of the moving rod 9. The moving rod 9 is connected to the moving block 10 through the guide groove 13, and the moving rod 9 is slidably connected to the guide groove 13, so that the moving rod 9 is slidably connected to the moving block 10. When the moving rod 9 is displaced, the moving block 10 can be driven to displace through the guide groove 13, so that the connecting rod 11 can be displaced, and the clamping block 12 can be displaced.

[0029] Secondly, a limit block 14 is provided on the outside of the moving rod 9 and inside the sleeve 8, and a compression spring 15 is provided on the outside of the limit block 14. The compression spring 15 is connected to the moving rod 9 through the limit block 14. By connecting the compression spring 15 to the limit block 14, the limit block 14 can be driven to move by the compression spring 15, so that the moving rod 9 can move.

[0030] Furthermore, multiple groups of snap-fit ​​grooves 16 are provided inside the connecting shaft 3. The internal structure and size of the snap-fit ​​grooves 16 are designed to correspond to the external structure and size of the snap-fit ​​block 12. The connecting shaft 3 is connected to the snap-fit ​​block 12 through the snap-fit ​​grooves 16. The snap-fit ​​block 12 is connected to the snap-fit ​​grooves 16 so that the snap-fit ​​block 12 can be limitedly connected to the connecting shaft 3.

[0031] Furthermore, the interior of the third connecting shell 7 and located on the outside of the connecting shaft 3 is rotatably connected to a first spiral blade 17, and a plurality of guide blades 18 are provided on the outside of the first spiral blade 17. The interior of the first connecting shell 2 and located on the outside of the connecting shaft 3 is rotatably connected to a second spiral blade 19, and a third spiral blade 20 is provided on the outside of the second spiral blade 19. When the water flow is introduced into the interior of the nozzle body 1, the water flow can be accelerated by the first spiral blade 17 in cooperation with the plurality of guide blades 18 on its outside. When the water flow is ejected, it is guided and accelerated by the second spiral blade 19 and the third spiral blade 20, so that the ejected water has better linearity and a better spray distance.

[0032] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the filter cartridge 5 needs to be installed, the second connecting shell 4 and the third connecting shell 7 are removed, and then the first spiral blade 17 is removed from the outside of the connecting shaft 3, and the moving rod 9 is pressed to drive the moving block 10 to move through the guide groove 13, so that the connecting rod 11 drives the clamping block 12 to move to the inside of the filter cartridge 5, and the filter cartridge 5 is moved to the outside of the connecting shaft 3. When the filter cartridge 5 is moved to the specified position, the moving rod 9 is loosened, and the limit block 14 can be driven to move by the compression spring 15, so that the moving rod 9 can be moved. When the moving rod 9 is displaced, the moving block 10 can be driven to move through the guide groove 13, so that the connecting rod 11 can be displaced, driving the clamping block 12 is displaced, and the clamping block 12 is connected with the clamping groove 16, so that the clamping block 12 can be limitedly connected with the connecting shaft 3, so that the filter cartridge 5 can be connected with the connecting shaft 3, and the second connecting shell 4, the third connecting shell 7 and the first spiral blade 17 are reset. The water flow introduced into the nozzle body 1 can be filtered through the filter cartridge 5 to prevent impurities carried by the water flow from adhering to the inside of the nozzle body 1, causing the nozzle body 1 to be blocked and affecting the use. There is no need to frequently replace the nozzle, which greatly reduces the user's use cost, and can filter the water to prevent water containing impurities from affecting the operating efficiency and components of the loom and the quality of the fabric. Compared with the existing nozzles, the utility model can improve the overall practicality of the nozzle through design.
