Description

Technical Field

[0001] This invention relates to the field of chemical fiber texturing technology, and in particular to an oiling device for fine denier polyester elastic yarn and a method for modifying the oiling gear. Background Technology

[0002] Existing polyester elastic yarn texturing machines all use oiling gears to oil the processed elastic yarn. The oiling gears are installed between the three rollers and the winding mechanism of the texturing machine, forming a continuous shaft that rotates at a certain speed. The oiling agent in the oil tank is carried to the top through the toothed grooves on the oiling gears. The elastic yarn has a certain length of contact with the top of the oiling gear, thus achieving oiling and meeting the needs of conventional polyester elastic yarn production. However, when using oiling gears to oil fine denier polyester elastic yarn, the large amount of oil carried by the toothed grooves results in an oil content more than twice the standard. If the contact length between the fine denier polyester elastic yarn and the top of the oiling gear is reduced, the oiling time between the yarn and the oil is too short, leading to severely uneven oiling and failing to meet the oil content requirements of subsequent weaving processes. For fine denier polyester elastic yarn, a suitable and uniform oiling rate is a necessary condition for ensuring the weaving of downstream textile enterprises. Therefore, a new technical solution is urgently needed to solve at least one of the above technical problems. Summary of the Invention

[0003] In view of the above shortcomings, one object of the present invention is to provide an oiling device for fine denier polyester elastic yarn, which reduces the amount of oil carried while providing a suitable oiling rate for fine denier polyester elastic yarn to meet the requirements of subsequent weaving processes regarding the oil content of fine denier polyester elastic yarn. Another object of the present invention is to provide a method for modifying oiling gears, which does not damage the original structure of the oiling gears, can meet different oiling needs, is easy to disassemble and assemble, and has high production efficiency.

[0004] To achieve the aforementioned technical objective and meet the aforementioned technical requirements, the technical solution adopted by this invention is as follows:

[0005] A device for oiling polyester fine denier elastic yarn is characterized in that it includes an oiling gear and an oiling belt detachably covered on the oiling gear. The surface of the oiling belt facing the oiling gear is provided with a serrated portion, which meshes with the oiling gear. The surface of the oiling belt facing away from the oiling gear is the oiling surface, and the oiling surface is provided with a plurality of micropores.

[0006] As a preferred technical solution, each end of the oiling belt is provided with at least two fastening holes distributed along the axial direction of the oiling gear, and fasteners are provided in the fastening holes.

[0007] As a preferred technical solution, the oiling strip is made of a flexible hydrophobic polymer material.

[0008] As a preferred technical solution, the flexible hydrophobic polymer material is any one of polyamide, polyphenylene sulfide, polyimide, and polyurethane.

[0009] As a preferred technical solution, the fastener is a fixing pin.

[0010] As a preferred technical solution, an adhesive material is provided in the gap between the two ends of the oiling strip.

[0011] As a preferred technical solution, the adhesive material is polyamide glue.

[0012] The present invention also provides a method for modifying oiled gears, characterized in that the modification is carried out using the aforementioned oiling device, and includes the following steps:

[0013] Micropores are machined on the oiling surface of the oiling strip;

[0014] The oiling tape with micropores is tightened onto the oiling gear, and then the oiling tape is fixed in place with a fixing pin;

[0015] After fixing, gaps are formed at both ends of the oiled strip. The gaps are filled with glue and then sanded smooth.

[0016] As a preferred technical solution, the oil surface is etched using an atmospheric pressure plasma machine to form micropores.

[0017] As a preferred technical solution, the glue is polished smooth with sandpaper after it has solidified.

[0018] Compared with traditional technical solutions, the beneficial effects of the present invention are:

[0019] 1) The existing oiling gear is covered with an oiling belt, and oiling is carried out through the micropores on the oiling belt, which reduces the amount of oil carried and provides a suitable oiling rate for polyester fine denier elastic yarn to meet the requirements of subsequent weaving for the oil content of polyester fine denier elastic yarn.

[0020] 2) Preferably, a fastener is provided in the fastening hole to facilitate installation and disassembly. More preferably, the fastener is a fixing pin, which has a good fastening effect.

[0021] 3) Preferably, the flexible polymer material has good flexibility and good clamping effect. More preferably, the flexible polymer material is any one of polyamide, polyphenylene sulfide, polyimide, and polyurethane, which has good corrosion resistance and extends service life.

[0022] 4) Preferably, the gaps are filled with glue, so that the surface remains seamless, avoiding snagging of the elastic yarn and uneven oiling. In addition, the connection between the two ends of the oiled tape after tightening is more secure, and it can also fix the fixing pin, resulting in a better fixing effect.

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "top", "bottom", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0033] Reference Figures 1-5An embodiment of the present invention provides an oiling device for polyester fine denier elastic yarn, comprising an oiling gear 1 and an oiling belt 2 detachably wrapped around the oiling gear 1. The surface of the oiling belt 2 facing the oiling gear 1 has a serrated portion 201 that meshes with the oiling gear 1. The surface of the oiling belt 2 facing away from the oiling gear 1 is an oiling surface 202, which has a plurality of densely distributed micropores that tighten the oiling belt 2 onto the oiling gear 1. A toothed groove 101 is provided between two adjacent teeth of the oiling gear 1. The serrated part 201 enters the toothed groove 101 and meshes with the oiling gear 1. In this way, the oiling band 2 rotates with the oiling gear 1, and the elastic oiling agent in the oil groove is carried out by the micropores. This makes the oil content of the polyester fine denier elastic yarn and the smooth oiling surface 202 containing micropores controllable under the same contact length, reducing the amount of oil carried while ensuring the oiling rate of the fine denier polyester elastic yarn to meet the requirements of the subsequent weaving process for the oil content of the polyester fine denier elastic yarn. Furthermore, the micropores are evenly set, which ensures that the oiling of the fine denier polyester elastic yarn is more uniform.

[0034] like Figures 1-5 As shown, in some embodiments, at least two fastening holes 203 are provided at each end of the oiling belt 2, which are distributed along the axial direction of the oiling gear 1. Fasteners 3 are provided in the fastening holes 203. Further, the fasteners 3 are fixing pins. One end of the fixing pin is fixedly disposed in one of the fastening holes 203, and the other end is inserted into the other fastening hole 203 to lock it in place, thereby fixing both ends of the oiling belt 2 and preventing the oiling belt 2 from falling off. The fixing method of the oiling belt 2 will not be described in detail.

[0035] like Figures 1-5 As shown, in some embodiments, the oiling tape 2 is made of a flexible polymer material, further, any one of polyamide, polyphenylene sulfide, polyimide, and polyurethane. Preferably, the oiling tape 2 is made of polyamide. The oiling tape 2 made of flexible polymer material has a smooth surface, preventing excess elastic oiling agent from sticking on it. In addition, polyamide, polyphenylene sulfide, polyimide, and polyurethane have good corrosion resistance, which extends the service life of the oiling tape 2, has good oil absorption effect, and improves the oiling rate of polyester fine denier elastic yarn.

[0036] like Figures 1-5 As shown, in some embodiments, adhesive material is provided in the gap between the two ends of the oiling tape 2. Since the oiling tape 2 rotates with the oiling gear 1, even though fasteners such as fixing pins are provided, the oiling tape 2 may still fall off during rotation. Moreover, after the oiling tape 2 is tightened, a gap will be generated between its two ends, which will affect the oiling of the polyester fine denier elastic yarn. Therefore, the gap is filled with adhesive material, so the continuity of the entire oiling surface 202 is better, and the oiling effect of the polyester fine denier elastic yarn is improved. Generally, the oiling tape 2 is made of polyamide, so polyamide glue is used as the adhesive material for better results.

[0037] This invention also provides a method for modifying oiled gears, which involves using an oiling device and includes the following steps:

[0038] Microholes are machined on the oiling surface 202 of the oiling belt 2. The oiling belt 2 with microholes is then tightened onto the oiling gear 1. The oiling belt 2 is then fixed with fixing pins. After fixing, gaps are formed at both ends of the oiling belt 2. Glue is filled into the gaps and then the surface is polished smooth.

[0039] Existing technology often requires replacing the entire oiling gear 1 when oiling fine denier polyester elastic yarn, which is costly and inconvenient to disassemble and assemble. In addition, regular elastic yarn also needs to be oiled. After the fine denier polyester elastic yarn is oiled, the oiling gear 1 must be replaced again, which greatly increases the cost and wastes time. This invention uses an oiling belt 2 to tighten onto an oiling gear 1. The oiling belt 2 has a serrated section 201 that meshes tightly with the oiling gear 1. It is then fixed with a fixing pin, allowing the oiling belt 2 to rotate with the oiling gear 1 without damaging its original structure. After tightening with the oiling belt 2, a gap will remain between its two ends. This gap is filled with glue and then polished smooth, resulting in better continuity of the oiling surface 202. Maintaining a seamless oiling surface 202 avoids snagging on the polyester fine denier elastic yarn and uneven oiling, leading to better oiling results. After modification, the elastic oiling agent is carried out through the micro-holes. Compared to the oiling gear 1, the amount of oil applied is significantly reduced, but the oiling rate of the polyester fine denier elastic yarn is still guaranteed, meeting different oiling needs. It is easy to assemble and disassemble, and has high production efficiency. After the polyester fine denier elastic yarn is oiled, the oiling belt 2 can be removed.

[0040] like Figures 1-5 As shown, in some embodiments, the upper oil surface 202 is etched using an atmospheric pressure plasma machine to form micropores. These micropores are densely distributed on the upper oil surface 202, and their diameters are extremely small. Specifically, this can be seen from... Figure 4 As can be seen, the oiling tape 2 is made of a flexible polymer material to ensure that the oiling surface 202 is a smooth surface. This ensures that the oiling of the polyester fine denier elastic yarn is more stable and smooth, and will not cause yarn breakage or fuzzing. However, the surface of the flexible polymer material is too smooth, which will also affect the adhesion. As a result, the elastic oiling agent cannot adhere to the oiling surface 202, resulting in a low oiling rate. Therefore, an atmospheric pressure plasma machine is used to etch micropores to improve its surface properties, wettability and adhesion. In this way, the elastic oiling agent can adhere to the oiling surface 202, improve the oiling uniformity of the polyester fine denier elastic yarn and increase the oiling rate of the polyester fine denier elastic yarn.

[0041] like Figures 1-5 As shown, in some embodiments, the adhesive is polished with sandpaper after it has solidified to prevent the surface from becoming rough and affecting the oiling of the polyester fine denier elastic yarn.

Polyamide glue is filled into the gaps. After the polyamide glue solidifies, it is polished smooth with polishing sandpaper. The oiling surface 202 is etched to form micropores using an atmospheric pressure plasma etching machine.
