Description

Technical Field

[0001] The utility model relates to the technical field of polyester filament production, in particular to a two-pass oiling device for sixteen-end spinning of polyester industrial filament. Background Art

[0002] The second oiling device for polyester industrial filament sixteen-head spinning refers to the equipment that oils the filaments that have been oiled once again during the filament spinning process. The main function is to increase the lubricity of the filaments, reduce the friction between fibers, reduce the generation of static electricity, and improve the spinning efficiency and spinning quality.

[0003] The patent with publication number CN215856485U discloses an oiling device for polyester filaments, which includes a frame, a guide wheel arranged on the frame, a material receiving mechanism arranged on the frame, and an oiling mechanism arranged between the material receiving mechanism and the guide wheel; the oiling mechanism includes an oil box fixed on the frame, and a slot arranged on the top of the oil box. The device can drive the oiling roller to rotate counterclockwise through a transmission belt, so that the oiling roller is always adhered to oil; the oil adhered to the upper oil groove can flow from both ends to the middle through an arc-shaped cross-section, so that the filaments can be fully contacted with the oil and the oiling is uniform. However, the device has the problem that the polyester filaments to be oiled pass through the guide wheel and the upper groove. After the oiling groove on the oil roller is passed, the oiled polyester filament is wound on the receiving roller in conjunction with structures such as a motor and a conveyor belt. Although there is a baffle inside the device to cover the oiling roller to prevent excess oil on the oiling roller from being thrown out of the oil outlet box, the oiled polyester filament will still be mixed with a lot of oil during the process of being wound on the receiving roller, so that there will be oil droplets on the filaments between the oiling roller and the receiving roller, as well as during the process of the receiving roller winding the polyester filament, which will not only pollute the oiling device, but also cause oil waste. For this reason, a two-pass oiling device for sixteen-head spinning of polyester industrial filament is proposed to solve the problem that the existing oiling device is prone to oil waste during the winding process.

The movable plate 9 is fixedly connected to the oil shield 7. There is a minimum friction force between the movable plate 9 and the movable groove 8 that can make the two relatively static. Before oiling, when the polyester filament passes through the guide roller 2, the oiling roller 3 and the winding roller 4, the oil shield 7 can be moved to the far right. With the friction between the movable plate 9 and the movable groove 8, the position of the oil shield 7 is automatically fixed, which is convenient for the arrangement of the polyester filament. The oil shield 7 and the movable groove 8 are both tilted and arranged on one side of the inner cavity of the U-shaped seat 1. The top of the receiving plate 12 is flush with the bottom of the movable groove 8. The inner cavity surface of the oil shield 7 is very smooth. The right side of the receiving plate 12 exceeds the left side of the movable groove 8. It is ensured that when the movable plate 9 moves to the far left side of the movable groove 8, the top of the left side of the oil shield 7 is located above the receiving plate 12, which is convenient for the subsequent oil to flow into the oil inlet 11 for recovery. The two gears 14 are respectively fixedly connected to the rotating shaft 5 of the fixed oiling roller 3 and the winding roller 4, and the output shaft of the reduction motor 15 is fixedly connected to the rotating shaft 5 of the oiling roller 3.

[0025] The greasing mechanism 13 includes an extrusion groove 131 opened at both ends of the inner cavity of the U-shaped seat 1, the inner cavity of the extrusion groove 131 is provided with a connecting block 132 and a spring 134, the top of the connecting block 132 is fixedly connected with a pull rod 133, the pull rod 133 passes through the extrusion groove 131 and the U-shaped seat 1, and the pull rod 133 is connected by a connecting plate 137. A fixing rod 135 is fixedly connected between the two connecting blocks 132, and a plurality of rollers 136 are rotatably connected to the outer ring of the fixing rod 135. The plurality of rollers 136 correspond to the positions of the upper oil groove and are slightly smaller in width than the upper oil groove. The connecting block 132 in the extrusion groove 131 is moved upward together with the fixing rod 135 by using the connecting plate 137 in cooperation with the pull rod 133, so that after the roller 136 is moved out of the upper oil groove, the polyester filament is put into the upper oil groove, and then the connecting plate 137 is sent away, and the spring 134 is cooperated to make the roller 136 fit with the polyester filament, and then when the oiling roller 3 is rotated to oil the polyester, the roller 136 is also soaked in the oil in the upper oil groove, so that the top of the polyester filament is oiled, thereby ensuring the oiling effect of this oiling device. A slide groove 16 is provided at the bottom of the inner cavity of the U-shaped seat 1, and a slider 17 is provided in the inner cavity of the slide groove 16. The slider 17 is fixedly connected to the oil collecting box 10, and a handle 18 is fixedly connected to one side of the oil collecting box 10. The slide groove 16 is aligned with the right side of the oil storage tank 6. After all the polyester filaments are oiled, the handle 18 can be used to cooperate with the slider 17 in the slide groove 16 to extract the oil collecting box 10 from the bottom of the oil storage tank 6 to recover and process the oil inside. Otherwise, the oil collecting box 10 can be installed in the U-shaped seat 1 to continue to recover the excess oil, thereby achieving the purpose of unified recovery and treatment of the excess oil.

[0026] Working principle: Using this two-stage oiling device for sixteen-head spinning of polyester industrial filament, the polyester filament is guided by the guide roller 2 and then placed in the oiling tank inside the oiling roller 3, and then wound in the winding roller 4. The speed reducing motor 15 is turned on to cooperate with the rotating shaft 5 to drive the oiling roller 3 to rotate counterclockwise, and the oil is transferred into the oiling tank to oil the polyester. Through two gears 14, the winding roller 4 rewinds the polyester filament while cooperating with the oiling mechanism 13 to oil it from above the polyester filament to ensure the oiling effect; during the oiling process, the movable plate 9 in the movable groove 8 can be used to move the oil shield 7 to cover the winding roller 4, and then the oiled polyester filament can be wound. During the process, excess oil will drip onto the smooth oil shield 7 and cooperate with the receiving plate 12 to flow from the oil inlet 11 to the oil collecting tank 10 for recovery, which solves the problem of oil waste easily caused during the winding process of the existing oiling device.
