Description

Technical Field

[0001] This invention relates to the field of ES fiber oiling technology, and more particularly to an ES fiber oiling blower. Background Technology

[0002] During fiber production, fibers are affected by various external factors, such as oxidation, ultraviolet rays, and friction, which can damage the fiber surface. Oiling can form a protective film, effectively preventing damage to the fiber surface and extending the fiber's service life.

[0003] Oiling ES fibers requires strict control of the amount of oiling agent used. Too much oiling agent will make the fiber surface greasy, affecting the appearance and feel of the textile, while too little oiling agent will not achieve the expected oiling effect.

[0004] In addition, a fiber production oiling device is disclosed in Chinese patent with authorization announcement number CN215925160U, which belongs to the field of fiber production technology. The key points of its technical solution include a placement frame, a horizontal support fixedly connected to the rear end of the placement frame, a vertical support provided on the left side of the horizontal support, and an upper roller and a lower roller movably connected to the upper and lower sides of the front end face of the vertical support, respectively. Fiber feeding roller sleeves and fiber receiving roller sleeves are respectively sleeved on the outer walls of the upper roller and the lower roller.

[0005] However, during the fiber oiling process, the oiling roller rotates to apply oil, which cannot make the oiling of the fiber uniform and is also difficult to control the amount of oil applied, thus resulting in poor oiling effect; therefore, this application proposes an ES fiber oiling blowing device. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems by providing an oiling and blowing device for ES fibers.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An oiling and blowing device for ES fibers includes an upper oil tank. An inlet tube and an outlet tube are coaxially arranged and fixedly connected through the upper oil tank. A fan is mounted on the upper oil tank. A U-shaped tube is installed at the outlet end of the fan. An inclined tube is fixed to the bottom of the U-shaped tube, and a bent tube is fixed to the end of the U-shaped tube. The inclined tube passes through the outlet tube and has a through hole. The bent tube passes through the inlet tube. An oil inlet thin tube is installed at the end of the U-shaped tube near the bent tube. A fixedly connected sleeve is fitted onto the inlet tube. A rotating tube is rotatably connected to the sleeve. Multiple spiral blades are fixed on the inner wall of the rotating tube. A guide tube is rotatably installed on the rotating tube. When the fan operates, it blows a high-speed airflow into the U-shaped tube. When the air passes through the oil inlet tube, it can draw the oil in the upper oil tank into the U-shaped tube and blow it into the yarn inlet tube through the bend tube. The air blown onto the spiral blades can make the spiral blades and the rotating tube rotate, so that the air and atomized oil are spirally transported into the guide tube. The spiral atomized oil can cover the ES fiber, thus applying oil to the ES fiber.

[0008] Preferably, the end of the bend is tapered, and the end of the bend faces the rotating pipe.

[0009] Preferably, it further includes an ES fiber guiding mechanism, which includes a bracket mounted on the upper oil tank. A first drive shaft is rotatably mounted through the bracket. A coaxial drive wheel is fixed on the first drive shaft. A spiral guide groove is wound around the drive wheel. The ES fiber is wound around the guide groove and passes through the inlet tube, the rotating tube, the guide tube, and the through hole.

[0010] Preferably, the system further includes an air intake dust removal mechanism, which includes a circular filter cover connected to the air intake end of the fan. A baffle plate that can block the upper part is fixed on the circular filter cover. Two support plates are fixed horizontally along the diameter direction of the circular filter cover. The two support plates do not abut against each other. A short shaft that is rotatably configured and can rotate with the first drive shaft is passed through the two support plates. A stainless steel dustproof mesh is fixed on the short shaft. A fixing ring is fixed on the outside of the stainless steel dustproof mesh. The fixing ring slides against the inner wall of the circular filter cover. A cleaning brush that abuts against the stainless steel dustproof mesh is fixed on the baffle plate.

[0011] Preferably, the air inlet end of the fan is equipped with a support pipe, which passes through the circular filter cover and is fixedly connected to it, and the support pipe is located below the center of the circular filter cover.

[0012] Preferably, it further includes a transmission mechanism, which includes a first bevel gear fixed on a short shaft, a support block fixed on the baffle plate, a second transmission shaft rotatably connected to the support block, a second bevel gear fixedly connected to the second transmission shaft, the second bevel gear meshing with the first bevel gear, and synchronous pulleys installed on both the first and second transmission shafts, the two synchronous pulleys being connected by a transmission belt.

[0013] Preferably, it further includes a cleaning mechanism capable of cleaning the cleaning brush. The cleaning mechanism includes a negative pressure pipe that passes through and is slidably connected to a circular filter cover. The negative pressure pipe can slide against the cleaning brush. A horizontal block is installed on the baffle plate. A rotatably mounted third transmission shaft passes through the horizontal block. A third bevel gear is fixed on the third transmission shaft. The third bevel gear meshes with a first bevel gear. A reciprocating screw is fixedly connected to the third transmission shaft. A connecting block is rotatably connected to the upper end of the reciprocating screw. A guide rod is fixedly connected to the bottom of the connecting block. The guide rod is fixedly connected to the horizontal block. A movable block is slidably connected to the guide rod. The reciprocating screw passes through the movable block and is engaged with it. An exhaust pipe connected to the negative pressure pipe is installed through the upper oil tank.

[0014] Preferably, a flexible hose is installed on the negative pressure pipe, and the flexible hose is connected to the exhaust pipe.

[0015] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Through the design of the fan and U-shaped tube, the Bernoulli distance is used to deliver the oil to the infeed tube and generate oil mist, so that the oil layer can be evenly covered on the fiber surface and the oiling effect can be improved.

[0016] 2. The air generated by the fan, together with the spiral blades, can drive the rotating tube and the spiral blades to rotate, forming a spiral oil mist that can evenly cover the fiber surface, thus achieving high-quality oiling of the fibers.

[0017] 3. By controlling the fan speed, the airflow speed inside the U-shaped tube can be adjusted, thereby precisely controlling the amount of atomized oil generated and further controlling the amount of oil applied to the fiber, avoiding excessive or insufficient oil from affecting fiber quality.

[0018] 4. Some of the atomized oil adheres to the surface of the rotating tube and guide tube due to centrifugal force, and is blown back to the upper oil tank by airflow, thus achieving effective oil recovery and reducing waste.

[0019] 5. Through the design of the inclined tube and through hole, the excess oil on the surface of the ES fiber is sucked away by negative pressure, which avoids the oil being squeezed and falling to the ground during winding, thus keeping the working environment clean.

[0020] 6. The stainless steel dust filter can filter impurities in the air. At the same time, through the design of the transmission mechanism and cleaning brush, the dust filter can be automatically cleaned, avoiding clogging problems.

[0021] In summary, this invention utilizes the Bernoulli principle to atomize the oil through a fan and U-shaped tube design, forming a spiral oil mist with the help of the spiral blades and rotating tube, ensuring high-quality oil application. By adjusting the fan speed, the amount of oil applied can be controlled, and the oil can also be recovered and reused. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1-10 An ES fiber oiling and blowing device includes an upper oil tank 1. An inlet tube 3 and an outlet tube 2 are coaxially arranged and fixedly connected through the upper oil tank 1. A fan 5 is installed on the upper oil tank 1. A U-shaped tube 10 is installed at the outlet end of the fan 5. An inclined tube 12 is fixed at the bottom of the U-shaped tube 10 and a bent tube 11 is fixed at the end of the U-shaped tube 10. The inclined tube 12 passes through the outlet tube 2 and has a through hole 13 for the ES limiter to pass through. The bent tube 11 passes through the inlet tube 3 and has a constricted end facing the rotating tube 8. An oil inlet capillary tube 40 is installed at the end of the U-shaped tube 10 near the bent tube 11. The upper oil tank 1 contains oil, and the oil inlet capillary tube 40 is located in the oil.

[0026] A fixed sleeve 7 is fitted onto the inlet tube 3. A rotating tube 8 is rotatably connected to the sleeve 7. Multiple spiral blades 14 are fixed on the inner wall of the rotating tube 8. A guide tube 9 is rotatably installed on the rotating tube 8. A bracket can be installed in the upper oil tank 1. When the blower 5 works, it blows a high-speed airflow into the U-shaped tube 10. When the air passes through the oil inlet capillary tube 40, it can draw the oil in the upper oil tank 1 into the U-shaped tube 10 and blow it into the inlet tube 3 through the bend tube 11. The air blown onto the spiral blades 14 can make the spiral blades 14 and the rotating tube 8 rotate, so that the air and the atomized oil are spirally transported to the guide tube 9. The spiral atomized oil can cover the ES fiber and apply oil to the ES fiber.

[0027] It also includes an air intake dust removal mechanism, which includes a circular filter cover 6 connected to the air intake end of the fan 5. The air intake end of the fan 5 is equipped with a support pipe 34, which passes through the circular filter cover 6 and is fixedly connected to it. The support pipe 34 is located below the center of the circular filter cover 6.

[0028] A baffle plate 41 that can block the upper part is fixed on the circular filter cover 6. The circular filter cover 6 is horizontal and has two support plates 36 fixed along the diameter direction. The two support plates 36 do not abut each other. A short shaft 35 that is rotatably configured and can rotate with the first drive shaft 15 is provided through the two support plates 36. The filter cover 6 also includes a transmission mechanism. The transmission mechanism includes a first bevel gear 25 fixed on the short shaft 35. A support block 23 is fixed on the baffle plate 41. A second drive shaft 24 that is rotatably connected to the support block 23 is provided through the support block 23. A second bevel gear 26 is fixedly connected to the second drive shaft 24. The second bevel gear 26 meshes with the first bevel gear 25. Synchronous pulleys 19 are installed on both the first drive shaft 15 and the second drive shaft 24. The two synchronous pulleys 19 are connected by a transmission belt 18.

[0029] A stainless steel dustproof mesh 38 is fixed on the short shaft 35. A fixing ring 37 is fixed on the outside of the stainless steel dustproof mesh 38. The fixing ring 37 slides against the inner wall of the circular filter cover 6. A cleaning brush 39 is fixed on the baffle plate 41 and abuts against the stainless steel dustproof mesh 38.

[0030] Since the cleaning brush 39 produces filtered material when cleaning the stainless steel dust filter 38, it needs to be cleaned. A cleaning mechanism is also included to clean the cleaning brush 39. This mechanism includes a negative pressure pipe 33 that passes through and is slidably connected to the circular filter cover 6. The negative pressure pipe 33 can slide against the cleaning brush 39. A horizontal block 29 is mounted on the baffle plate 41, and a rotating third drive shaft 28 passes through the horizontal block 29. A third bevel gear 27 is fixed on the third drive shaft 28. The third bevel gear 27 interacts with the first bevel gear 25. The reciprocating screw 30 is fixedly connected to the third drive shaft 28. The upper end of the reciprocating screw 30 is rotatably connected to the connecting block 22. The bottom of the connecting block 22 is fixedly connected to the guide rod 31. The guide rod 31 is fixedly connected to the cross block 29. The guide rod 31 is fitted with a sliding block 32 that is slidably connected to it. The reciprocating screw 30 passes through the sliding block 32 and is connected to it. The upper oil tank 1 is connected to the exhaust pipe 20 that is connected to the negative pressure pipe 33. The negative pressure pipe 33 is fitted with a hose 21 that is connected to the exhaust pipe 20.

[0031] When this invention is used, the ES fiber is wound in the guide groove 17, and then passes through the inlet tube 3, sleeve 7, rotating tube 8, guide tube 9, through hole 13 and outlet tube 2 in sequence. After passing through the outlet tube 2, it is wound on the tensioning mechanism or wound up, so that the ES fiber is taut. Driven by fan 5, the operation of fan 5 causes external air to be filtered through stainless steel dustproof mesh 38 and delivered into U-shaped tube 10. The high-speed airflow passes through the upper end of oil inlet capillary tube 40 and is finally discharged through bend 11. Due to the high airflow velocity at the upper end of oil inlet capillary tube 40, the pressure at the upper end is low and the pressure at the bottom of oil inlet capillary tube 40 is high. The pressure difference between the two ends of oil inlet capillary tube 40 can force the oil through oil inlet capillary tube 40 into U-shaped tube 10 (Bernoulli's principle). Finally, it is discharged through bend 11 with the air and is in atomized form, thus forming oil mist. The oil mist is blown into the rotating tube 8 by the air and passes through the spiral blade 14, which drives the spiral blade 14 to rotate. This principle is similar to the rotation of a fan in flowing air. The rotating tube 8 and the spiral blade 14 form a shaftless fan. The rotation of the rotating tube 8 and the spiral blade 14 will cause the air and atomized oil passing through the spiral blade 14 to form a spiral shape. Finally, the spiral air and atomized oil are delivered to the guide tube 9. The spiral atomized oil can adhere to the surface of the ES fiber, achieving uniform oiling of the ES fiber. Compared with the existing technology, the oiling effect is better and will not cause excessive oil volume to affect the quality of the ES fiber. Some of the atomized oil adheres to the surface of the rotating tube 8 and the guide tube 9 due to centrifugal force. As the air flows in the direction of the guide tube 9, the oil in the rotating tube 8 and the guide tube 9 can be blown outward, eventually detaching from the guide tube 9 and falling into the upper oil tank 1, thus realizing the recovery of the oil. When high-speed air passes through the U-shaped tube 10, it also passes above the inclined tube 12. When the oiled ES fiber passes through the through hole 13, since the outlet tube 2 contains air, the air will flow through the through hole 13 and the surface of the ES fiber into the inclined tube 12, and finally enter the U-shaped tube 10. In this way, the oil on the surface of the ES fiber can be sucked away by negative pressure, so as to prevent the oil from being squeezed and falling to the ground during winding, which would cause the ground to become wet or difficult for subsequent workers to clean.

[0032] The ES fiber is wound up and moved. The ES fiber moves within the guide groove 17, which in turn drives the drive wheel 16 to rotate. The rotation of the drive wheel 16 drives the first drive shaft 15 to rotate. With the cooperation of the synchronous pulley 19 and the drive belt 18, the second drive shaft 24 rotates. The rotation of the second drive shaft 24 drives the second bevel gear 26 to rotate. The rotation of the second bevel gear 26 drives the first bevel gear 25 to rotate. The rotation of the first bevel gear 25 drives the short shaft 35 to rotate. The rotation of the short shaft 35 drives the stainless steel dustproof mesh 38 and the fixing ring 37 to rotate. In this way, the position of the air filtered by the stainless steel dustproof mesh 38 is constantly changing, avoiding the easy clogging of the stainless steel dustproof mesh 38 when it is used in a fixed position. As the stainless steel dust filter 38 rotates, the surface of the stainless steel dust filter 38 can be cleaned by the cleaning brush 39 to prevent the filter material from accumulating and causing blockage. The cleaning brush 39 will cause the filter material to accumulate at the cleaning brush 39. If it is not cleaned, the cleaning effect will be reduced, which will reduce the filtration effect of the stainless steel dust filter 38. As the blower 5 continuously supplies air into the upper oil tank 1, the air pressure in the upper oil tank 1 increases, causing some air to be discharged through the exhaust pipe 20. When the air is discharged through the exhaust pipe 20, the air velocity at the opening of the hose 21 is high, while the air velocity at the opening of the negative pressure pipe 33 is low. According to Bernoulli's principle, a negative pressure will be generated at the opening of the negative pressure pipe 33. Therefore, the filter material on the cleaning brush 39 can be sucked away and discharged through the exhaust pipe 20. It can also suck away the filter material on the stainless steel dustproof mesh 38, thus cleaning the stainless steel dustproof mesh 38 and the cleaning brush 39. To better clean the cleaning brush 39, the first bevel gear 25 rotates, driving the third bevel gear 27 to rotate. The third bevel gear 27 rotates, driving the third transmission shaft 28 to rotate, which in turn drives the reciprocating screw 30 to rotate. Since the moving block 32 is guided by the guide rod 31 and cannot rotate, the reciprocating screw 30 rotates to move the moving block 32 up and down, which in turn drives the negative pressure pipe 33 to move up and down. The up and down movement of the negative pressure pipe 33 can effectively clean the stainless steel dustproof net 38 and the radius length of the cleaning brush 39 without manual intervention. As mentioned above, the ES fibers can be wound or stretched to ensure continuous and uniform oiling, thus guaranteeing the quality of the oiling. By controlling the rotation speed of the fan 5, the airflow speed inside the U-shaped tube 10 can be controlled, thereby controlling the amount of atomizing oil produced and further controlling the amount of oil applied to the fiber. The control is simple.

[0033] Since the ES fiber is wound in the guide groove 17 to drive the transmission wheel 16 to rotate, the tensile fracture quality of the ES fiber can also be detected. If it is broken, it is unqualified; otherwise, it is qualified.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
