Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of oiling devices for chemical fiber spinning, specifically to an inner lip type oiling device for chemical fiber spinning. Background Technology
[0002] In the production process of chemical fiber spinning, the polyester melt, the raw material for spinning, enters the spinning box for spinning after passing through the melt conveying system. It is then cooled and shaped into undrawn filaments by ring blowing, and then wound, drawn, and fed into the filament holding tank before finally being sent to the post-processing stage.
[0003] Currently, in general, during the spinning process, undrawn yarn bundles are directly fed into the winding machine without separate oiling, or the machine has a single-sided oiling device. The yarn bundles oscillate due to the influence of the ring airflow, resulting in uneven oiling and affecting the quality of the oiling. This, in turn, can easily lead to static electricity and roller entanglement in subsequent spinning processes, increasing the labor intensity of operators and impacting product quality. Furthermore, most oiling trays on the market use ceramic spraying technology for structural simplification; however, in actual use, the ceramic layer is prone to peeling off over time, significantly increasing maintenance difficulty and cost. Summary of the Invention
[0004] The purpose of this utility model is to address the problems in the related technologies by proposing an inner lip oiling device for chemical fiber spinning, so as to overcome the aforementioned technical problems existing in the existing related technologies.
[0005] The technical solution of this utility model is as follows: This utility model includes an upper oil pan and a lower oil pan, characterized in that it further includes an oil inlet, an oil receiving pan, an oil return connector, a positioning pin, an upper lip, a toothed pad, and a lower lip. The upper surface of the upper oil pan tapers downwards from the inside to the outside, and the inner hole is a flared opening. The upper lip, toothed pad, and lower lip are detachably installed between the upper and lower oil pans in sequence from top to bottom via the positioning pin. Both the upper and lower lip are made of ceramic material, and the oil outlet between them is a rounded flared opening. The oil inlet communicates with the rounded flared opening. An oil storage groove is provided below the rounded flared opening on the lower lip. The oil receiving pan is located below the lower oil pan, and the oil return connector is installed at the bottom of the oil receiving pan.
[0006] The inner hole of the oiling tray is flared, which guides the yarn bundle as it falls into the tray, preventing it from scattering and piling up, thus affecting normal spinning. The upper surface of the oiling tray tapers downwards from the inside to the outside. Because the direction of the circumferential airflow is consistent with the yarn bundle's movement, when the circumferential airflow blows onto the upper surface of the oiling tray, it will run outwards along the slope, greatly improving the stability of the yarn bundle's movement. If the upper surface of the oiling tray were flat or conical, the circumferential airflow would blow towards the yarn bundle, causing it to oscillate and affecting the oiling quality. The toothed pad between the upper and lower lips naturally separates the oil outlet gap, allowing the oil to evenly overflow from the gap to form an oil film zone for the yarn bundle's first oiling. The circumferential teeth ensure uniform oil distribution, facilitating the first oiling of the yarn bundle. The lower lip is equipped with an oil reservoir, which has the function of storing oil to form an oil film. The oil overflowing from the arc-shaped flared opening between the upper and lower lip can provide secondary oiling for the filament bundle, effectively increasing the oiling time and amount. This increases the cohesion of the filament bundle, improves its antistatic properties, reduces friction between the filament bundle and the equipment, and between filament bundles, thereby improving the post-processing performance of the filament bundle.
[0007] The beneficial effects of this utility model are: simple structure, high spinning quality, and by using detachable upper and lower lip plates made of ceramic material to replace the ceramic spraying process on the oil pan surface, the maintenance difficulty and cost are greatly reduced.

[0013] like Figures 1 to 3As shown, this utility model includes an upper oil pan 1 and a lower oil pan 3. It is characterized by further including an oil inlet 2, an oil receiving pan 4, an oil return connector 5, a positioning pin 8, an upper lip 9, a toothed pad 10, and a lower lip 11. The upper surface of the upper oil pan 1 tapers downwards from the inside to the outside, and its inner hole is a flared opening. The upper lip 9, the toothed pad 10, and the lower lip 11 are detachably installed between the upper oil pan 1 and the lower oil pan 3 sequentially from top to bottom via the positioning pin 8. Both the upper lip 9 and the lower lip 11 are made of ceramic, and their oil outlet is a rounded flared opening. The oil inlet 2 communicates with the rounded flared opening. An oil storage groove 12 is provided below the rounded flared opening on the lower lip 11. The oil receiving pan 4 is located below the lower oil pan 3, and the oil return connector 5 is installed at the bottom of the oil receiving pan 4.
[0014] The inner hole of the oiling tray 1 is a funnel shape, which guides the filament bundle 7 when it falls into the tray, preventing it from scattering and piling up, thus affecting normal spinning. The upper surface of the oiling tray 1 tapers downwards from the inside to the outside. Since the direction of the annular blower 6 is consistent with the movement of the filament bundle 7, when the annular blower 6 blows onto the upper surface of the oiling tray 1, it will run outwards along the slope, greatly improving the running stability of the filament bundle 7. If the upper surface of the oiling tray 1 is a flat surface or an inner conical surface, the annular blower 6 will blow onto the filament bundle 7 when it blows onto the oiling tray 1, causing the filament bundle 7 to oscillate, thus affecting the oiling quality. The toothed pad 10 between the upper lip 9 and the lower lip 11 can naturally separate the oil outlet gap. The oil evenly overflows from the gap of the toothed pad 10 to form an oil film area for the filament bundle 7 to be oiled once. The circumferential tooth shape can ensure the uniformity of the oil outlet, which is beneficial for the first oiling of the filament bundle 7. The lower lip 11 is provided with an oil storage tank 12, which has the function of storing oil to form an oil film. The oil overflowing from the arc-shaped flared opening between the upper lip 9 and the lower lip 11 can provide secondary oiling for the filament bundle 7, which can effectively increase the oiling time and amount of the filament bundle 7. This can increase the cohesion of the filament bundle 7, improve the antistatic performance of the filament bundle 7, reduce the friction between the filament bundle 7 and the equipment, and between the filament bundle 7 and other filament bundles, and improve the post-processing performance of the filament bundle 7.
[0015] The beneficial effects of this utility model are: simple structure, high spinning quality, and by using detachable upper lip 9 and lower lip 11 made of ceramic material to replace the ceramic spraying process on the oil pan surface, the maintenance difficulty and cost are greatly reduced.
