Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical fiber spinning, specifically to an outer ring oiling device. Background Technology
[0002] In the chemical fiber spinning process, the filaments from the spinning box are oiled in an oil pan, cooled by ring blowing, and then sent to the next process. There are generally two methods for oiling the filaments: inner ring and outer ring. Strict control of the oil output and uniformity is required; otherwise, abnormal phenomena such as fuzzy filaments, broken filaments, and roller entanglement may occur. Currently, the outer ring oiling device has several shortcomings: First, the filament separating disc and the oiling disc are integrated, making the separating frame prone to inward deformation when heated. This causes the outer edge of the oiling disc to warp upwards, resulting in uneven oil output and a low oiling rate. Second, the upper and lower oiling discs are either made of stainless steel with a ceramic-coated surface or entirely of ceramic material. Ceramic-coated stainless steel is prone to deformation, leading to unstable oiling and easy peeling of the coating, resulting in waste filaments. Fully ceramic materials are difficult to process and costly. Third, relying on the boss of the lower oiling disc for positioning increases processing difficulty and reduces positioning accuracy, easily causing unstable oil output. Summary of the Invention
[0003] The purpose of this utility model is to address the problems in the related technologies by proposing an outer ring oiling device to overcome the aforementioned technical problems existing in the existing related technologies.
[0004] 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 a thread dividing disc, a positioning rod, a toothed gasket, oil inlet and outlet pipe fittings, an oil receiving pan, an upper oil nozzle, and a lower oil nozzle. The thread dividing disc is mounted on the positioning rod, which is sequentially embedded from top to bottom into the inner hole of the upper oil pan and the groove of the lower oil pan. The oil inlet and outlet pipe fittings and the oil receiving pan are both mounted at the bottom of the lower oil pan. The upper oil nozzle and the lower oil nozzle are detachably mounted on the outer edges of the upper and lower oil pans, respectively. The toothed gasket is installed between the upper and lower oil nozzles to form a toothed oil passage. The lower oil pan has an oil inlet hole, an A-shaped circumferential oil groove, several radial oil grooves, and a B-shaped circumferential oil groove sequentially opened from the inside to the outside. The B-shaped circumferential oil groove communicates with the toothed oil passages. The oil inlet hole and the oil receiving pan are connected to the oil inlet and outlet pipe fittings. During operation, the oil enters the inlet hole through the inlet and outlet pipes and passes through the A circumferential oil groove, radial oil groove, and B circumferential oil groove in sequence. Then, it is evenly distributed to the outer ring lip between the upper and lower oil nozzles through the toothed oil passage. The toothed oil passage can make the oil output more uniform.
[0005] As a preferred option, both the upper and lower oil nozzles are made of all-ceramic Al2O3, which is dimensionally stable and does not deform, has a small size and low cost, and can ensure uniform oiling and stable oiling rate.
[0006] Preferably, guide blocks are installed on both sides of the inlet and outlet oil pipe fittings. The surface of the guide blocks is coated with Al2O3 to prevent the wire bundle from getting caught when passing through the inlet and outlet oil pipe fittings.
[0007] Preferably, the outer end face of the lower oil nozzle is machined with a storage groove, where the oil can be stored and form an oil film. When the filament bundle passes through this groove, a small amount of oil will be applied again, which is the second oiling.
[0008] The beneficial effects of this utility model are as follows: This utility model can perform two oiling processes on the filament bundle, resulting in a high oiling rate; the filament separating disc and the oiling disc are independently separated, avoiding the impact of heat deformation on oiling; upper and lower oil nozzles are added to the outer edges of the upper and lower oiling discs, and the upper and lower oil nozzles are made of small, non-deformable, all-ceramic material, ensuring dimensional stability, low cost, and stable and uniform oiling; independent guide rods are set up, which can simultaneously position the upper and lower oiling discs; the lower oiling disc uses a groove for positioning instead of a convex groove, allowing the upper surface of the lower oiling disc to be machined in one cut, reducing the machining difficulty of the lower oiling disc, improving the positioning accuracy of the upper and lower oiling discs, and solving the aforementioned problems existing in the industry.

Detailed Implementation
[0015] like Figures 1 to 4As shown, this utility model includes an upper oil pan 2 and a lower oil pan 3. Its features include a thread splitting disc 1, a positioning rod 4, a toothed gasket 5, oil inlet / outlet pipe fittings 6, an oil receiving pan 7, an upper oil nozzle 8, and a lower oil nozzle 9. The thread splitting disc 1 is mounted on the positioning rod 4, which is sequentially embedded from top to bottom into the inner hole of the upper oil pan 2 and the groove of the lower oil pan 3. The oil inlet / outlet pipe fittings 6 and the oil receiving pan 7 are both mounted at the bottom of the lower oil pan 3. The upper oil nozzle 8 and the lower oil nozzle 9 are detachably mounted on the outer edges of the upper oil pan 2 and the lower oil pan 3, respectively. The toothed gasket 5 is mounted on the upper oil nozzle 8 and the lower oil nozzle 9. A toothed oil passage 10 is formed between the oil nozzles 9; the lower oil pan 3 has an oil inlet hole 301, an A-shaped oil groove 302, several radial oil grooves 303 and a B-shaped oil groove 304 sequentially from the inside to the outside, and the B-shaped oil groove 304 communicates with the toothed oil passage 10; the oil inlet hole 301 and the oil receiving pan 7 are connected to the oil inlet and outlet pipe fittings 6; the upper oil nozzle 8 and the lower oil nozzle 9 are both made of all-ceramic Al2O3; guide wire blocks 11 are installed on both sides of the oil inlet and outlet pipe fittings 6, and the surface of the guide wire blocks 11 is sprayed with Al2O3; the outer circular end face of the lower oil nozzle 9 is machined with a storage groove 901.
[0016] During operation, the oil enters the inlet hole 301 through the inlet / outlet pipe 6, then passes sequentially through the A circumferential oil groove 302, the radial oil groove 303, and the B circumferential oil groove 304. It is then evenly distributed through the toothed oil channel 10 to the outer lip between the upper oil nozzle 8 and the lower oil nozzle 9, serving as the first stage of oiling for the filament bundle. The toothed oil channel 10 ensures more uniform oil distribution. Both the upper and lower oil nozzles 8 and 9 are made of all-ceramic Al2O3, ensuring dimensional stability and no deformation. Their small size and low cost guarantee uniform oiling and a stable oiling rate. Guide blocks 11 are installed on both sides of the inlet / outlet pipe 6 to prevent filament snagging as the filament bundle passes through the inlet / outlet pipe 6. Then, the excess oil from the first oiling process flows downwards into the storage groove 901 of the lower oil nozzle 9, where the oil can be stored and form an oil film. When the filament bundle passes through this area, it will be oiled again in a small amount, which is the second oiling process. After that, any excess oil flows to the oil receiving tray 7 and then back to the inlet and outlet oil pipes 6.
[0017] The beneficial effects of this utility model are as follows: This utility model can perform two oiling processes on the filament bundle, resulting in a high oiling rate; the filament separating disc 1 and the oiling disc 2 are independently separated, avoiding the impact of heat deformation on oiling; an upper oiling nozzle 8 and a lower oiling nozzle 9 are added to the outer edges of the upper oiling disc 2 and the lower oiling disc 3, respectively. The upper oiling nozzle 8 and the lower oiling nozzle 9 are made of small, non-deformable, all-ceramic material, ensuring dimensional stability, low cost, and stable and uniform oiling; an independent positioning rod 4 is provided, which can simultaneously position the upper oiling disc 2 and the lower oiling disc 3; the lower oiling disc 3 uses a groove for positioning instead of a convex groove, allowing the upper surface of the lower oiling disc 3 to be machined in one cut, reducing the machining difficulty of the lower oiling disc, improving the positioning accuracy of the upper oiling disc 2 and the lower oiling disc 3, and solving the aforementioned problems existing in the industry.
