Description

Technical Field

[0001] The invention relates to the technical field of textile engineering, in particular to a polyester staple fiber spinning wet-feeding and oiling device. Background Art

[0002] Polyester staple fiber spinning is a key process in the production of polyester (polyethylene terephthalate, PET). It is mainly used to process high molecular polymer melt or solution into short fiber products. It is widely used in textiles, clothing, home textiles, industrial fabrics and other fields. The polyester staple fiber spinning wet oiling equipment is a key equipment used to complete the wet oiling process in the production of polyester staple fibers. Its main function is to evenly apply an appropriate amount of oil on the fiber surface to improve the physical properties of the fiber (such as smoothness, antistatic properties, bundling, etc.) to ensure the smooth progress of subsequent spinning, weaving and other processing procedures. In the field of polyester staple fiber production, the wet oiling process is a key link to ensure the subsequent processing performance of the fiber.

[0003] Traditional polyester staple fiber spinning wet-oiling equipment often utilizes fixed-structure oiling rollers and a single oiling method during the fiber squeezing and oiling process. This makes it difficult to precisely adjust the fiber's oil content, resulting in uneven oil distribution on the fiber surface, which in turn affects the fiber's antistatic properties, smoothness, and other properties, and reduces the quality and stability of the textile products. Secondly, the oil circulation system is poorly designed, and excess oil cannot be effectively recovered and filtered. This not only results in oil waste and increases production costs, but also pollutes the environment. The cleanliness of the circulating oil cannot be guaranteed, affecting the oiling effect. Thirdly, the fiber winding process has a low degree of automation, relying heavily on manual adjustment of the line arrangement. This makes it difficult to achieve uniform winding, and is prone to problems such as fiber stacking and loose winding, resulting in substandard package quality and reduced production efficiency. With the textile industry's increasing requirements for polyester staple fiber quality and the tightening of energy-saving and environmental protection policies, it is necessary to develop a new type of spinning wet-oiling equipment that can achieve precise control, efficient circulation, and automated production to meet the industry's high-quality development needs.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example: Figure 1-8As shown, the present invention provides a polyester staple fiber spinning wet oiling equipment, including a first bracket 11 and a second bracket 12. The first bracket 11 and the second bracket 12 are vertically fixed to a flat surface with high-strength bolts, ensuring that the bracket spacing meets the requirements of the design drawings and firmly supports the entire equipment. On one side of the upper surface of the second bracket 12, a side support plate 19 is fixed by welding, serving as the mounting base for the wire guide device 16; the other side is connected to the oil tank 15 by bolts, ensuring that the oil tank 15 is firmly installed and there is no risk of leakage. At the same time, an oil squeezing device 17 and a winding device 18 are installed at corresponding positions on the upper surface of the first bracket 11, and each component is fixed by bolts or welding to ensure a tight connection. A protective cover 13 is fixedly installed on the upper surface of the second bracket 12 by bolts, and an exhaust box 14 is fixedly installed on the top of the protective cover 13. The protective cover 13 is made of high-strength transparent material, such as PC board or stainless steel frame and tempered glass. Openings for spinning are opened on both sides of the protective cover 13. An exhaust motor and an exhaust fan are installed inside the exhaust box 14 to ensure that the exhaust system can effectively discharge moisture and volatile gases generated during the operation of the equipment.

[0026] The wire guide device 16 is mounted on one side of the side support plate 19. Multiple wire rollers 20 are installed sequentially at the designed spacing. The wire rollers 20 are rotatably connected to the side support plate 19 via bearings to ensure flexible rotation. Synchronous pulleys 21 are fixedly sleeved onto one end of each wire roller 20 and extended out of the side support plate 19. Subsequently, a synchronous belt 25 is wrapped around the outer surfaces of the multiple synchronous pulleys 21, and the tension of the synchronous belt 25 is adjusted to the appropriate level. Finally, a variable frequency motor 24 is fixedly mounted on the upper surface of the side support plate 19. The output end of the variable frequency motor 24 is connected to one of the synchronous pulleys 21 via a connecting shaft 23 to ensure stable power transmission. A tensioning pulley 22 is installed on the side of the side support plate 19 facing the synchronous pulley 21, with its outer surface abutting against one side of the synchronous belt 25, ensuring that the synchronous belt 25 maintains a suitable tension. An encoder monitors the speed of the variable frequency motor 24 in real time, automatically adjusting the speeds of the third servo motor 43 and the drive motor of the winding drum 40 to ensure that the fiber feed speed matches the winding line speed. The variable frequency motor 24 is then started, driving the synchronous pulley 21 to rotate via the connecting shaft 23, which in turn drives the synchronous belt 25 in a circular motion, causing multiple guide rollers 20 to rotate synchronously, pulling the polyester staple fiber bundle from the spinning process into the equipment. During this process, the tensioning pulley 22 always abuts against the outside of the synchronous belt 25, ensuring the appropriate tension of the synchronous belt 25 and stabilizing the fiber feed speed.

[0027] The oil squeezing device 17 is mounted on the inner wall of one side of the first vertical plate 26 and the second vertical plate 27. The first transmission block 30 is slidably connected via a slideway, ensuring that the first transmission block 30 can slide smoothly between the vertical plates. The first squeezing roller 32 is rotatably connected to one side of the two first transmission blocks 30 via bearings, allowing the first squeezing roller 32 to rotate freely. Simultaneously, a second squeezing roller 33 is rotatably mounted on the lower portion of the first and second vertical plates 26, 27 via bearings, ensuring that the first and second squeezing rollers 32, 33 are parallel and adjustable in spacing. A threaded rod 29 is mounted inside the second vertical plate 27, rotatably connected to the second vertical plate 27 via bearings. A first servo motor 31 is fixedly mounted on the upper end of the second vertical plate 27, with the output end of the first servo motor 31 fixedly connected to the threaded rod 29. The threaded rod 29 extends through the first transmission block 30 and is threadedly engaged with the first transmission block 30. This ensures that when the first servo motor drives the threaded rod 29 to rotate, the first transmission block 30 drives the first squeezing roller 32 up and down. In addition, a bidirectional screw rod 35 is installed inside the lower support plate 34, and a second servo motor 37 is fixedly installed on one side of the lower support plate 34. The output end of the second servo motor 37 is fixedly connected to the bidirectional screw rod 35, and two third oil squeezing rollers 36 are symmetrically threaded on the outer surface of the bidirectional screw rod 35, so that when the second servo motor 37 drives the bidirectional screw rod 35 to rotate, the two third oil squeezing rollers 36 move toward or away from each other, and cooperate with the first oil squeezing roller 32 and the second oil squeezing roller 33 to extrude the fiber. According to the fiber specifications and process requirements, the first servo motor 31 is started through the control box 51 to drive the threaded rod 29 to rotate, so that the first transmission block 30 drives the first oil squeezing roller 32 to move up and down, and adjusts the distance between the first oil squeezing roller 32 and the second oil squeezing roller 33 to obtain a suitable oil squeezing pressure; at the same time, the second servo motor 37 is started to drive the bidirectional screw rod 35 to rotate, so that the two third oil squeezing rollers 36 move toward or away from each other, further fine-tuning the pressure in the oil squeezing area to ensure that the oil content in the width direction of the fiber bundle is uniform.

[0028] In the winding device 18, the front frame 38 and the lower surface of the support frame 39 are fixedly connected to the first bracket 11 by bolts to ensure a secure installation. On the upper surface of the front frame 38, the winding drum 40 is rotatably connected via a bearing so that the winding drum 40 can rotate freely. Inside the support frame 39, a reciprocating screw 42 is installed so that it is rotatably connected to the support frame 39 via a bearing, and a third servo motor 43 is fixedly installed on one side of the support frame 39, with the output end of the third servo motor 43 fixedly connected to the reciprocating screw 42. A screw nut seat 45 is installed on the outer surface of the reciprocating screw 42, and the wire tube 44 is slidably connected to the reciprocating screw 42 through the screw nut seat 45. A screw drive key 47 is installed on the screw nut seat 45 so that the screw drive key engages with the reciprocating thread groove on the outer surface of the reciprocating screw 42, so that when the third servo motor 43 drives the reciprocating screw 42 to rotate, the wire tube 44 moves back and forth horizontally. Simultaneously, slide rails are symmetrically mounted on the upper surface of support frame 39. Two sliders are slidably connected to the rails, and the upper surfaces of the sliders are fixedly connected to the lower surface of wire tube 44. A guide limit plate 46 is mounted on the lower surface of wire tube 44 to ensure the movement accuracy of wire tube 44 and achieve uniform fiber arrangement. A third servo motor 43 is activated to drive the reciprocating screw 42 to rotate. The screw drive key 47 cooperates with the reciprocating thread groove on the screw surface, causing wire tube 44 to reciprocate laterally along the slide rails on support frame 39. Simultaneously, the winding drum 40 rotates at a constant speed driven by the reducer 41. The wire tube 44 guides the fiber to be evenly wound around the winding drum 40, forming a regular fiber roll. During the winding process, the guide limit plate 46 and the screw nut seat 45 ensure the movement accuracy of the wire tube 44 and prevent the fiber from winding and deflecting.

[0029] An oil drain port 48 is opened at a suitable position on the inner surface of the oil tank 15, and an impregnation roller 49 and a temperature sensor are symmetrically installed inside the oil tank 15, so that the impregnation roller 49 is rotatably connected to the oil tank 15 through a bearing; at the same time, a heating copper tube 50 is installed inside the oil tank 15 to heat the oil agent. One end of the return oil pipe 57 is connected to the oil drain port 48 at the bottom of the oil tank 15, and the other end is connected to the input end of the filter 52; the control box 51 and the filter 52 are fixedly installed at a suitable position on the inner wall of the second bracket 12, and the output end of the filter 52 is connected to the inside of the oil tank 15 through the oil delivery pipe 55, and the oil pump 54 and the manual valve 53 are installed on the oil delivery pipe 55 in sequence. A one-way valve is installed on one side of the oil delivery pipe 55 to ensure the one-way flow of the oil during the oil delivery process to reduce the resistance to the flow of the oil, ensure that the output end of the oil pump 54 is fixedly connected to the oil delivery pipe 55, and realize the circulation filtration and pumping of the oil. When the fiber bundle passes through the oil tank 15, the impregnated roller 49 partially immersed in the oil rotates synchronously with the movement of the fiber, and the oil is evenly adhered to the roller surface. The oiling is completed during the contact between the fiber and the roller surface. The heating copper tube 50 is equipped with a PID temperature control module. Based on the data from the temperature sensor in the oil tank 15, it automatically adjusts the heating power to control the oil temperature fluctuation within ±1°C, adapting to the process temperature requirements of different oils (such as mineral oil and synthetic esters). The heating copper tube 50 continuously heats the oil, maintaining the oil temperature at around 50°C, ensuring oil fluidity and improving fiber wetting. Excess oil drips naturally through the oil drain port 48 or is diverted by the oil scraper structure into the return oil pipe 57. After the oil enters the filter 52 through the return oil pipe 57 to filter impurities, it is pressurized by the oil pump 54 and re-delivered to the oil tank 15 through the oil delivery pipe 55, forming a circulation system. The oil circuit is open and closed and the flow rate can be adjusted by the manual valve 53. The control box 51 monitors parameters such as the liquid level in the oil tank 15 and the pressure of the oil pump 54 in real time to ensure the stable operation of the oil circulation system.

[0030] Working Principle: When the equipment is in operation, the first bracket 11 and the second bracket 12 serve as the basic support structure, stably supporting various functional components. First, the variable frequency motor 24 starts, and power is transmitted to the synchronous pulley 21 via the connecting shaft 23. The synchronous pulley 21 drives the guide roller 20 to rotate synchronously via the synchronous belt 25. With the support of the side support plate 19, the wire guide device 16 pulls the polyester staple fiber bundle smoothly into the equipment. The tensioning pulley 22 presses against the synchronous belt 25 to ensure stable transmission and prevent slipping during fiber transportation.

[0031] The fiber bundle enters the oil tank 15. The impregnation roller 49 is partially immersed in the oil and rotates synchronously with the movement of the fibers, evenly adhering the oil to the fiber surface, completing the oiling process. The heating copper tube 50 heats the oil in the oil tank 15, maintaining it at a process temperature of 40 to 60 degrees Celsius to ensure fluidity. Excess oil flows through the oil drain port 48 into the oil return pipe 57. After being filtered by the filter 52 for impurities, it is pressurized by the oil pump 54 and returned to the oil tank 15 through the oil delivery pipe 55 for recycling. The manual valve 53 controls the oil circuit and flow rate, and the control box 51 coordinates the operation of various components.

[0032] After the fibers enter the oil tank 15 and are oiled, they pass through the oil squeezing device 17. The first servo motor 31 drives the threaded rod 29 to rotate, causing the first transmission block 30 to drive the first squeezing roller 32 to move up and down between the first vertical plate 26 and the second vertical plate 27, accurately adjusting the distance between it and the second squeezing roller 33. At the same time, the second servo motor 37 drives the bidirectional screw rod 35, driving the third squeezing roller 36 to move horizontally, squeezing oil from different directions to control the uniform oil content of the fibers.

[0033] Finally, the oiled fiber bundle enters the winding device 18. A third servo motor 43 drives the reciprocating screw 42. The screw drive key 47 engages the threaded groove of the reciprocating screw 42, driving the screw nut seat 45 and the connected wire tube 44 to perform horizontal reciprocating motion on the slide rails of the support frame 39. Simultaneously, the winding drum 40 rotates at a constant speed driven by the reducer 41, and the wire tube 44 guides the fiber to be evenly wound around the winding drum 40. Throughout this process, the protective cover 13 prevents oil from splashing, and the exhaust motor in the exhaust box 14 drives the exhaust fan to remove moisture and volatile gases from the equipment, ensuring a safe working environment.

[0034] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
