Description

Technical Field

[0001] The present application relates to the technical field of textile processing, and in particular to a polyester staple fiber oiling structure. Background Art

[0002] Polyester staple fiber is a fiber obtained by polymerizing raw materials such as polyethylene terephthalate (PET), PTA, and MEG, spinning them into polyester fiber tow, and then cutting them. Chemically produced polyester is manufactured into polyester staple fiber and polyester filament according to the requirements of the textile industry. During the production and processing of polyester staple fiber, it is necessary to apply oil to the fibers before cutting to ensure their antistatic properties, smoothness, and cohesiveness. After oiling, the polyester fibers must be dried promptly.

[0003] At present, a Chinese patent with announcement number CN210368014U discloses an oiling device for flat coarse denier polyester composite staple fiber, including a protective shell, a power box, an oiling chamber, a support column, a switch, a crimping wheel, a telescopic column and a roller. A switch is provided on one side of the protective shell, and the front end surface of the protective shell is connected to the crimping wheel through the support column, and a power box is installed inside the bottom end of the protective shell; an oiling chamber is provided inside the protective shell, and a telescopic column is provided at the rear end of the protective shell, and a roller is provided at the front and lower part of the telescopic column; the protective shell includes a power column and a second motor, and the power column is provided inside the protective shell, and the second motor is provided inside the power column.

[0004] Regarding the above-mentioned related technologies, the inventors believe that during the use of the above-mentioned oiling device for flat coarse denier polyester composite staple fibers, a certain amount of debris will adhere to the surface of the polyester fiber before the oiling operation. The presence of these debris will cause uneven oiling on the surface of the polyester fiber, thereby affecting the production quality of the polyester staple fibers. Utility Model Content

[0040] Reference Figure 2 and Figure 3 A collection trough 15 is provided below the guide roller 11. The top of the collection trough 15 is open. A collection hose 16 is connected to the collection trough 15. The end of the collection hose 16, away from the collection trough 15, is connected to a filter box 20. The top of the collection hose 16 is connected to the filter box 20, which is equipped with a filter plate 29 for filtering impurities. A first pump body 17 is connected to the collection hose 16. A return pipe 18 is connected to the bottom end of the filter box 20. The end of the return pipe 18, away from the filter box 20, is connected to the oil reservoir 36. A second pump body 19 is connected to the return pipe 18.

[0041] Reference Figure 1 and Figure 5 The drying component 5 is arranged in the drying box, and the drying component 5 includes a heating pipe 51, a flow equalizing plate 57, a guide plate 52, a drying fan 53, a drying header 54, a drying branch pipe 55 and a gas filter 56. Two flow equalizing plates 57 are horizontally connected in the drying box, and a plurality of flow equalizing holes are provided on the flow equalizing plates 57. The two flow equalizing plates 57 divide the drying box body 6 into a flow equalizing cavity at both ends and a drying cavity in the middle, and a plurality of guide plates 52 are obliquely arranged in the flow equalizing cavity. A heating pipe 51 is provided on each of the vertical inner walls on both sides of the width direction of the drying box body 6. The drying fan 53 is connected to one end of the drying header 54, the gas filter 56 is provided on the drying header 54, and two drying branch pipes 55 are connected to the drying branch pipe 55. The two drying branch pipes 55 correspond to the two flow equalizing cavities one by one and are connected.

[0042] Reference Figure 1 and Figure 2 When processing polyester fibers, the fibers first pass through the air shower frame 7. The first fan 10 is activated, and several air shower nozzles 8 are used to blow away debris from the polyester fibers, reducing the amount of debris on the fibers. The blown polyester fibers enter the oiling tank 1 through the line inlet 101. Two cleaning brushes 22 clean any remaining debris from the polyester fibers, helping to improve the quality of subsequent oiling. After a period of use, the two-way adjustment screw 23 is rotated, and the two mounting rods 21 move away from each other, driven by the two-way adjustment screw 23 and guided by the guide rod 24. The operator removes the mounting bolts 28 and removes the cleaning brushes 22 for cleaning.

[0043] Reference Figure 2-4 The cleaned polyester fibers pass through the support plate 31 via the communication port 311. The oil pump 35 is activated, spraying the oil from the oil reservoir 36 onto the surface of the polyester fibers via the oil hose 34, the upper oil ring 32, and the oil spray nozzle 33. The rotating motor 41 is activated, driving the rotating gear 42. The rotating ring gear 43, the rotating ring 44, and the upper oil ring 32 mounted thereon also rotate under the drive of the rotating gear 42. The output shaft of the rotating motor 41 periodically reciprocates, and the rotating ring 44 oscillates accordingly, ensuring a more uniform oil spray.

[0044] Reference Figure 2 and Figure 3 After being sprayed with oil, the polyester fibers pass over two guide rollers 11 and below an abutment roller 12 positioned between them. The tensioning action of these three rollers allows the oil on the fiber's surface to more fully penetrate the fiber's interior, improving the quality of the oil application. At the same time, the guide rollers 11 remove excess oil from the fibers, facilitating subsequent drying operations. The tensioning spring 14 ensures that the abutment roller 12 maintains constant contact with the polyester fibers, reducing the possibility of breakage due to excessive tension. A scraper 30 removes excess oil from the guide rollers 11, which then drips into a collection tank 15 located below. The first pump 17 is activated, and a collection hose 16 transfers the oil from the collection tank 15 to a filter box 20, where a filter plate 29 filters out impurities. The second pump 19 is activated, and the filtered oil flows back through a return pipe 18 to the oil reservoir 36 for reuse.

[0045] Reference Figure 1 and Figure 5The oiled polyester extends from the oiling box 1 through the outlet 102 and enters the drying box 6 through the drying inlet 61. The heating tube 51 heats the drying box, and the drying fan 53 draws air into the gas filter 56 for filtration. The filtered gas is then fed into the flow equalizer through two drying branch pipes 55. Guide plates 26 and flow equalizers 57, located within the flow equalizer chamber, equalize the airflow, allowing gas to enter the drying chamber from all directions. The high-temperature airflow dries the oiled polyester, accelerating the processing of polyester staple fibers.

[0046] The implementation principle of a polyester staple fiber oiling structure in the embodiment of the present application is as follows: when processing polyester fibers, the polyester fibers first pass through the air shower frame 7, and the polyester fibers that have been blown enter the oiling box 1, and the debris remaining by the cleaning brush 22 is cleaned. The cleaned polyester fibers pass through the support plate 31, and the oil pump 35 is started to spray the oil in the oil storage cylinder 36 onto the surface of the polyester fibers. The polyester fibers that have undergone the oil spraying operation pass over the two guide rollers 11 and under the abutting roller 12 arranged between the two, so that the grease on the fiber surface can be more fully immersed in the interior. The polyester that has undergone the oiling operation enters the drying box 6 from the drying inlet 61, and the high-temperature airflow performs a drying operation on the oiled polyester limit, which helps to speed up the processing speed of the polyester staple fibers.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
