Description

Technical Field

[0001] The utility model relates to the technical field of polyester fiber filament processing, in particular to a nozzle structure for polyester fiber filament processing. Background Technique

[0002] Fiber filaments such as cotton, wool, silk, and linen can be used to make yarns and textiles. A certain number of fine threads or fiber bundles are twisted together to form a thread. The combination of multiple fiber filaments can improve the strength. However, multiple fiber threads exist independently and need to be adhesively bonded together in a paragraph shape through a nozzle structure, which not only ensures their flexibility but also improves the tensile strength of the fiber threads.

[0003] However, when the nozzle outputs high-pressure air flow to spray and press multiple strands of threads, due to the looseness between the threads, the threads cannot be in an equidistant paragraph shape, and some paragraphs do not fully receive the spray and bonding of the high-pressure air flow. For this reason, we propose a nozzle structure for polyester fiber filament processing to solve the existing problems. Content of the Utility Model

[0004] The purpose of the utility model is to propose a nozzle structure for polyester fiber filament processing in view of the problems existing in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A nozzle structure for polyester fiber filament processing, including a nozzle body, an outer shell sleeve, and an inner shell sleeve. An outer shell sleeve is arranged at the upper end of the nozzle body. An inner shell sleeve is arranged inside the outer shell sleeve. The outer wall of the inner shell sleeve and the inner wall of the outer shell sleeve are both provided with a diversion arc surface, and the diversion arc surface is in a conical shape from bottom to top. A processing pipe is arranged inside the nozzle body, and a pressure medium delivery pipe is installed through the inside of the processing pipe. A spray head is arranged at one end of the pressure medium delivery pipe located inside the processing pipe.

[0006] Preferably, the lower edge side of the inner shell sleeve is connected to the inner wall of the outer shell sleeve, avoiding the air flow channel being communicated with the inside of the nozzle body from the lower end.

[0007] Preferably, wire outlet openings are respectively arranged inside the upper ends of the outer shell sleeve and the inner shell sleeve. An air flow channel is arranged between the outer shell sleeve and the inner shell sleeve, and the air flow channel is communicated with the wire outlet openings. The fiber threads are transported to the outside through the wire outlet openings, and the air flow channel guides the input air flow.

[0008] Preferably, an air inlet pipe is arranged inside the outer shell sleeve. The air inlet pipe transports air flow into the air flow channel.

[0009] Preferably, a bracket connected to the inner wall of the nozzle body is sleeved on the outer wall of the processing pipe, and a wire inlet opening is arranged inside the lower end of the nozzle body. The processing pipe is fixed inside the nozzle through the bracket, and the fiber threads are transported into the nozzle body through the wire inlet opening.

[0010] Preferably, guide wheels are symmetrically arranged inside the nozzle body. Both ends of the guide wheels are rotatably installed on the inner wall of the nozzle body, and annular wire grooves are formed on the inner wall of the nozzle body. The guide wheels are rotationally supported inside the nozzle body, and the fiber wires are guided and conveyed through the wire grooves.

[0011] Preferably, filter meshes are embedded at both ends of the nozzle body, and grids connected to the inner wall of the nozzle body are arranged at both ends of the filter meshes. The filter meshes intercept foreign matters from the outside. The high-pressure air flow output by the nozzle head is output to the outside through the internal mesh holes of the filter meshes, and at the same time, the grids support the filter meshes to improve their strength.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. An outer shell sleeve and an inner shell sleeve are arranged at the upper end of the nozzle body structure of the present utility model. The flow guiding arc surface formed between the outer shell sleeve and the inner shell sleeve converges the air flow inside the outer shell sleeve and the inner shell sleeve upward to the central position, converges multiple fiber wires to the central position, so that when the multiple fiber wires are conveyed inside the nozzle, they are attached together. When the high-pressure air flow is sprayed and pressed, the loose wires are sprayed and pressed into an equidistant distribution and adhered together in a paragraph shape.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-4 shown, a nozzle structure for processing polyester fiber filaments proposed by the present invention includes a nozzle body 5, an outer shell sleeve 1 and an inner shell sleeve 7. An outer shell sleeve 1 is provided at the upper end of the nozzle body 5. An inner shell sleeve 7 is provided inside the outer shell sleeve 1. The lower side of the inner shell sleeve 7 is connected to the inner wall of the outer shell sleeve 1. The outer wall of the inner shell sleeve 7 and the inner wall of the outer shell sleeve 1 are both provided with a flow guiding arc surface 12, and the flow guiding arc surface 12 is conical from bottom to top. Outlet ports 8 are opened inside the upper ends of the outer shell sleeve 1 and the inner shell sleeve 7. An air flow channel 9 is provided between the outer shell sleeve 1 and the inner shell sleeve 7, and the air flow channel 9 communicates with the outlet port 8. A processing pipe 11 is provided inside the nozzle body 5. A pressure medium delivery pipe 6 is installed through the inside of the processing pipe 11. A spray head 15 is provided at one end of the pressure medium delivery pipe 6 located inside the processing pipe 11. An air inlet pipe 2 is provided inside the outer shell sleeve 1. A bracket 10 connected to the inner wall of the nozzle body 5 is sleeved on the outer wall of the processing pipe 11. An inlet port 14 is opened inside the lower end of the nozzle body 5. Symmetrically distributed guide wheels 13 are provided inside the nozzle body 5. Both ends of the guide wheels 13 are rotatably installed on the inner wall of the nozzle body 5. Annular wire grooves 16 are opened on the inner wall of the nozzle body 5. Filter meshes 3 are embedded at both ends of the nozzle body 5. Grids 4 connected to the inner wall of the nozzle body 5 are provided at both ends of the filter meshes 3.

[0021] Based on the implementation steps of Embodiment 1: Multiple fiber lines enter the processing pipe 11 through the inlet port 14 and move in the wire grooves 16 inside the guide wheels 13. During this process, the air inlet pipe 2 conveys air flow into the air flow channel 9, and the air flow flows upward through the air flow channel 9. When flowing, the air flow is converged from the side to the center by the flow guiding arc surface 12, and the loose fiber lines are converged and adhered together. The pressure medium delivery pipe 6 conveys high-pressure air flow, which acts on the multiple adhered fiber lines inside the pressure pipe. By pressurizing the fiber lines, the fiber lines are adhered together at the force application points. According to needs, an adhesive liquid material can be mixed in the high-pressure air flow, and the adhesive liquid material adheres to the force application points of the multiple fiber lines. The pressure medium conveyed by the pressure medium delivery pipe 6 is output through the spray head 15, and operates in stages, so that the multiple fiber lines are adhesively bonded in an equidistant distributed and sectional manner, avoiding the situation that the lines are loose and some sections cannot be effectively bonded.
