Description

Technical Field

[0001] The utility model relates to the technical field of chemical fiber spinning, in particular to a chemical fiber spinning oiling device. Background Art

[0002] In the process of chemical fiber spinning, the spinning raw material polyester melt passes through the melt conveying system and enters the spinning box for spinning. It is formed into undrawn fibers by ring blowing cooling, and is wound, pulled, and fed to the fiber drum, and finally sent to the post-processing process.

[0003] At present, under normal circumstances, in the spinning production process, unstretched fibers enter the winding machine directly without separate oiling, or when there is a single-sided oiling device but uneven oiling, it will seriously affect the oiling quality of the yarn bundle, and then static electricity and roller entanglement will easily occur in the subsequent spinning process. This increases the labor intensity of the operators, wastes resources, and makes it difficult to improve product output and quality. Summary of the invention

[0004] The purpose of the utility model is to solve the problems in the related technology and propose a chemical fiber spinning oiling device to overcome the above technical problems existing in the existing related technology.

[0005] The technical solution of the utility model: The utility model includes an upper oil pan and a lower oil pan, and is characterized in that it also includes an oil return pan, the upper oil pan, the lower oil pan and the oil return pan are installed as a whole from top to bottom by fasteners in sequence, the top of the upper oil pan is a wire guide slope, the inner surfaces of the upper oil pan and the lower oil pan are sprayed with ceramic, and the gap between the two forms an oil storage chamber, an oil pressure channel, an oil pressure chamber and an oil outlet channel from the outside to the inside in sequence, the lower oil pan is provided with an oil inlet, the oil inlet is equipped with an oil inlet joint and is connected to the oil storage chamber; the lower end of the inner surface of the lower oil pan is an oil guide slope, the gap between the lower oil pan and the oil return pan forms an oil return chamber, the oil return pan is provided with an oil return port, the oil return port is equipped with an oil outlet joint and is connected to the oil return chamber.

[0006] The top of the upper oil tray is a wire guide slope, which plays a guiding role when the undrawn fiber bundle falls into the utility model, avoiding the scattered accumulation of fibers and affecting normal spinning. The oil used for spinning is transmitted from the oil supply tank to the oil inlet joint, and enters the oil storage chamber through the oil inlet. The oil storage chamber plays a role in storing and stabilizing the oil, avoiding the foaming and turbulence of the oil. After passing through the oil storage chamber, it enters the oil pressure channel to further evenly distribute the oil. Then the oil enters the oil pressure chamber. The oil pressure chamber plays a role in stabilizing the oil. Then the oil enters the oil outlet channel to evenly oil the bundle. The oil not absorbed by the bundle or the oil flowing out of the oil outlet channel can flow into the return oil chamber through the oil guide slope of the lower oil tray, and finally return to the oil supply tank through the oil return joint. It can be reused, effectively saving human resources and production costs.

[0007] Preferably, an oil replenishing groove is provided at the upper end of the inner surface of the lower oil pan. The oil replenishing groove has the function of storing oil. When the tow contacts the outlet of the oil outlet channel, the surface of the tow absorbs most of the oil. Since the tow runs very fast, some of the oil that is not absorbed by the tow flows directly into the oil replenishing groove. When the tow passes through the oil replenishing groove, the tow can be replenished with oil again, which can ensure that the tow absorbs more oil, effectively increase the time and amount of oiling the tow, increase the cohesion of the fiber, improve the antistatic performance of the fiber, reduce the friction between the fiber and the equipment, and between the fibers, and improve the post-processing performance of the fiber.

[0008] Preferably, a mounting positioning step is provided between the upper oil pan and the lower oil pan, and an adjustment pad is installed on the mounting positioning step. The number of the adjustment pads can be increased or decreased according to different spinning varieties, so as to adjust the gap between the upper oil pan and the lower oil pan, and then adjust the gap of the oil outlet channel, so as to control the oil output of the utility model.

[0009] The utility model has the following beneficial effects: the gap around the oil outlet channel is consistent, the filament bundle is evenly and fully oiled, the phenomenon of filament bundle winding around the roller in subsequent production can be avoided, and the quality of the spinning product is improved.

The upper oil pan 1, the lower oil pan 3, and the oil return pan 4 are installed as a whole from top to bottom through fasteners 2 in sequence, the top of the upper oil pan 1 is a wire guide slope, and the inner surfaces of the upper oil pan 1 and the lower oil pan 3 are sprayed with ceramics, and the gap between the two forms an oil storage chamber 8, an oil pressure channel 12, an oil pressure chamber 9 and an oil outlet channel 10 from the outside to the inside in sequence, and the lower oil pan 3 is provided with an oil inlet 15, and the oil inlet 15 is installed with an oil inlet joint 5 and is connected with the oil storage chamber 8; the upper end of the inner surface of the lower oil pan 3 is provided with an oil replenishing groove 11, and the lower end is an oil guide slope, and the gap between the lower oil pan 3 and the oil return pan 4 forms an oil return chamber 13, and the oil return pan 4 is provided with an oil return port 14, and the oil return port 14 is installed with an oil outlet joint 6 and is connected with the oil return chamber 13.

[0016] The top of the oil tray 1 is a wire guide slope, which plays a guiding role when the undrawn fiber bundle falls into the utility model, avoiding the fiber from being scattered and piling up, which affects the normal spinning. The oil used for spinning is transmitted from the oil supply tank to the oil inlet joint 5, and enters the oil storage chamber 8 through the oil inlet 15. The oil storage chamber 8 plays a role in storing and stabilizing the oil, avoiding the oil from foaming and turbulence. After passing through the oil storage chamber 8, it enters the oil pressure channel 12, and the oil is further evenly distributed. Then the oil enters the oil pressure chamber 9, which stabilizes the oil. Then the oil enters the oil outlet channel 10 to evenly oil the bundle. When the tow contacts the outlet of the oil outlet channel 10, the surface of the tow absorbs most of the oil. Since the tow runs very fast, some of the oil that is not absorbed by the tow flows directly into the oil replenishing groove 11. When the tow passes through the oil replenishing groove 11, the tow can be replenished with oil again, which can ensure that the tow absorbs more oil, effectively increase the time and amount of oiling the tow, increase the cohesion of the fiber, improve the antistatic performance of the fiber, reduce the friction between the fiber and the equipment, and between the fibers, and improve the post-processing performance of the fiber. The oil that is not absorbed by the tow or the oil that flows out of the oil outlet channel 10 can flow into the oil return chamber 13 through the oil guide slope of the lower oil plate 3, and finally return to the oil supply tank through the oil return joint 6, which can be reused, effectively saving human resources and production costs. The utility model can increase or decrease the number of adjustment pads 7 according to different spinning varieties, adjust the gap between the upper oil plate 1 and the lower oil plate 3, and then adjust the gap of the oil outlet channel 10, so as to control the oil output of the utility model. The beneficial effects of the utility model are as follows: the gap around the oil outlet channel 10 is consistent, the filament bundle is evenly and fully oiled, and the phenomenon of the filament bundle being entangled with the roller in subsequent production can be avoided, which is beneficial to improving the quality of the spinning product.
