Abstract
Description
Technical Field
[0001] This invention relates to the field of aramid fiber cleaning and drying, and in particular to a fiber cleaning and drying system for the production process of aramid UD fabric. Background Technology
[0002] At present, UD fabric made of ultra-high molecular weight polyethylene fiber is widely used in the field of bulletproof protection. However, with the improvement of domestic technology, relevant production companies engaged in this field have begun to gradually change the raw material of UD fabric from ultra-high molecular weight polyethylene to aramid fiber. The manufacturing process is similar, and bulletproof protective fabric is made by layering and laminating single-layer UD fabric.
[0003] Existing aramid fibers contain spinning oils, but the current impregnation methods mostly use water-based solvents, such as water-based polyurethane, epoxy, and isocyanate colloids. During the spinning process, the oils still adhere to the fiber surface or the gaps between the fibers, which hinders the penetration of water-based colloids and the adhesion of the fiber surface during the impregnation process. Therefore, an additional cleaning and drying system is needed during the spinning process to remove the oils and other substances that may affect the impregnation.
[0004] A Chinese invention (publication number: CN217869479U) discloses a cleaning device for para-aramid fibers, comprising: a frame; a fiber inlet on one side of the bottom end of the frame and a fiber outlet on one side of the bottom end of the frame; multiple cleaning frames disposed within the frame, the cleaning frames being inclined, wherein the distance between two adjacent cleaning frames is small on one side and large on the other side; multiple water-blocking rollers arranged in an array within the cleaning frames; and guide rollers symmetrically disposed on both sides of the cleaning frames via a rotating axis, the guide rollers being located on one side of the cleaning frames, and the deflecting rollers being located between the guide rollers and the fiber outlet. This invention, by setting multiple cleaning frames inclined at a certain angle, and with the cooperation of guide rollers, deflecting rollers, and spray pipes, can quickly and continuously perform multiple folding cleaning of the fibers, thereby achieving efficient fiber cleaning.
[0005] In the process of realizing this invention, the inventors discovered that the technology has at least the following problems: if cleaning is carried out by simply rinsing with a spray pipe, it is difficult to effectively remove the spinning oil, solvent and other impurities remaining on the surface of aramid fibers. In fact, during the transportation process, the cleaned aramid fibers may absorb dust, which will affect the adhesion between the fiber and the colloid in the subsequent textile impregnation production, thereby affecting the quality of aramid UD fabric. Therefore, a fiber cleaning and drying system for the production process of aramid UD fabric is now proposed. Summary of the Invention
[0006] To address the issue of residual spinning oil, solvents, and other impurities remaining after aramid fiber cleaning, and to prevent dust adsorption, this invention provides a fiber cleaning and drying system for the production process of aramid UD fabric.
[0007] This invention provides a fiber cleaning and drying system for the production process of aramid UD fabric, employing the following technical solution:
[0008] A fiber cleaning and drying system for the production process of aramid UD fabric includes a cleaning box with feeding ports on both sides of its outer wall. A drying box is located at one feeding port on the outer wall of the cleaning box, and a winding device body is detachably connected to the feeding port on the other side of the outer wall of the cleaning box via bolts. Door panels are embedded in the front ends of both the cleaning box and the drying box. A feeding mechanism is fixed at the lower interior of the cleaning box, and a cleaning mechanism is located above the feeding mechanism inside the cleaning box. Guide blocks are fixed on both sides of the bottom of the cleaning box, and a solenoid valve extends from the bottom of the cleaning box. Three second transmission cylinders are installed inside the drying box, and a drying mechanism is located at the top of the drying box. An adjustment mechanism is installed on the side of the drying box near the feeding port away from the cleaning box. An ultrasonic generator is embedded below the front door panel of the cleaning box.
[0009] By adopting the above technical solution, the feeding mechanism set in the cleaning box can tension the aramid fibers to prevent them from becoming loose and tangled, which would affect the cleaning quality. The aramid fibers are rinsed while being soaked in the cleaning mechanism, which further improves the cleaning quality and avoids the residue of impurities.
[0010] Optionally, the material conveying mechanism includes a support plate, which is obliquely and fixedly mounted on the inner wall of the cleaning tank, and a first transmission cylinder is rotatably connected to both ends of the support plate. A traction roller is rotatably connected to the inner wall of the cleaning tank located below the lower side of the support plate, and a limit collar is fixed to the outer wall of the traction roller.
[0011] By adopting the above technical solution, the aramid fibers can be straightened and conveyed through the traction roller and support plate, thereby avoiding the accumulation or entanglement caused by looseness, which would affect cleaning.
[0012] Optionally, the cleaning mechanism includes a through hole located below the rear end of the cleaning tank, and a conveying pipe extends through the through hole. One end of the conveying pipe is connected to a pump, and another set of conveying pipes extending from the other end of the pump is connected to a conveying hose. The two conveying hoses are respectively connected to corresponding water spray pipes, and the water spray pipes have multiple water spray holes evenly spaced on the outer wall of the support plate.
[0013] By adopting the above technical solution, the support plate facilitates the spraying of water from the water pipe for rinsing, and the addition of rinsing during soaking improves the cleaning effect.
[0014] Optionally, the cleaning mechanism further includes a miniature electric push rod, which is fixedly installed on the inner wall of the cleaning tank at one end of the water spray pipe, and a damping spring is fixedly installed at the end of the water spray pipe away from the miniature electric push rod.
[0015] By adopting the above technical solution, the water spray pipe is moved back and forth by a combination of a miniature electric push rod and a damping spring, thereby rinsing the gaps between the aramid fibers on the side.
[0016] Optionally, the pump is connected to the cleaning tank via a delivery pipe, and the delivery pipe is connected to the water spray pipe via a delivery hose. Meanwhile, the water spray pipe is elastically connected to the cleaning tank via a damping spring.
[0017] By adopting the above technical solution, the pump draws the solution from the inside of the cleaning tank through the delivery pipe and sprays it, thereby circulating and rinsing to avoid waste of resources.
[0018] Optionally, the drying mechanism includes a temperature-controlled hot air blower body, which is fixedly installed on one side of the top of the drying chamber, and a filter screen is embedded in the outer wall of the top of the temperature-controlled hot air blower body. An air supply pipe connects the temperature-controlled hot air blower body and the drying chamber.
[0019] By adopting the above technical solution, hot air is blown out by the main body of the temperature-controlled hot air blower and transported to the drying box through the air supply pipe for drying. This makes it easy to dry directly after cleaning and avoids excessive contact with air, which can lead to dust adsorption.
[0020] Optionally, the drying mechanism further includes a vacuum pump, which is embedded in both sides of the bottom of the drying chamber, and a gas storage shell is fixedly installed at the bottom of the drying chamber corresponding to the position of the vacuum pump. A reserved hole is opened at the bottom of the gas storage shell, and an air inlet pipe is inserted into the reserved hole.
[0021] By adopting the above technical solution, the vacuum pump can easily extract the hot air from inside the drying oven and discharge it through the air venting pipe, thus avoiding excessive internal air pressure that could prevent the oven from operating.
[0022] Optionally, the air intake pipe is connected to the drying chamber via a vacuum pump and an air storage shell, and the main body of the temperature-controlled hot air blower is detachably connected to the filter screen via bolts.
[0023] By adopting the above technical solution, the gas can be easily collected into the gas inlet pipe through the gas storage shell, thereby facilitating gas transportation.
[0024] Optionally, the adjustment mechanism includes a drive motor, which is embedded in the outer wall of the drying box near the main body of the winding equipment. The power output end of the drive motor is connected to a drive rod, and a rotating plate is fixed to the outside of the drive rod. A rubber pad is connected to the end of the rotating plate away from the drive rod.
[0025] By adopting the above technical solution, the drive motor drives the drive rod, which in turn drives the rotating plate to adjust the angle according to the looseness of the aramid fibers and press them tightly, so as to avoid the looseness causing accumulation and entanglement, which would affect the washing and drying.
[0026] Optionally, the rotating plate forms a rotating structure with the drive motor via a drive rod, and the rotating plate is bonded to the rubber pad.
[0027] By adopting the above technical solution, the rubber pad prevents the rotating plate from being too hard, which would cause excessive friction and damage to the aramid fibers when rotating along them.
[0028] In summary, the present invention has the following beneficial effects:
[0029] 1. This invention uses two sets of winding equipment to transport aramid fibers through a cleaning chamber and a drying chamber. In the cleaning chamber, a conveying mechanism tensions the aramid fibers to prevent loosening and tangling that could affect cleaning quality. The cleaning mechanism then rinses the aramid fibers while immersing them, further improving cleaning quality and preventing impurities from remaining. After cleaning, the aramid fibers enter the drying chamber, where they are supported by three triangular second conveyor cylinders and transported under tension. Simultaneously, the aramid fibers are unfurled to facilitate drying by the drying mechanism. Finally, an ultrasonic generator cleans the aramid fibers immersed in the cleaning chamber, significantly improving the removal of dirt and impurities.
[0030] 2. This invention adjusts and places aramid fibers by closing the cleaning box through the door panel, while simultaneously injecting cleaning solution until it submerges the traction roller. Two sets of support plates are provided to facilitate positioning and fit the aramid fibers, providing a certain tension to prevent loosening. First transmission cylinders are embedded at both ends of the support plates to improve the smoothness of aramid fiber transmission and avoid excessive friction that could damage the surface of the aramid fibers. The traction roller facilitates the aramid fibers to be immersed in the cleaning solution during transmission.
[0031] 3. This invention uses a pump to recycle the cleaning solution inside the cleaning tank via a delivery pipe to avoid waste. The pump delivers the cleaning solution to the delivery hose via the delivery pipe, and then into the water spray pipe and sprays it out through the spray holes. The spray holes are aimed at the aramid fibers on the support plate, thereby better rinsing and preventing the aramid fibers from bending or shaking due to the impact, which would result in incomplete rinsing. A miniature electric push rod pushes the water spray pipe to shake back and forth. The water spray pipe is elastically contracted by a damping spring, which helps to reduce shock when the water spray pipe shakes. The water spray pipe drives the sprayed water flow to shake along the aramid fibers, thereby better rinsing the gaps between the fibers.
[0032] 4. In this invention, hot air is delivered to the drying chamber through the air supply pipe by the main body of the temperature-controlled hot air blower. The air is then dried by the drying chamber. The filter screen prevents dust and impurities from entering the air absorbed by the main body of the temperature-controlled hot air blower and contaminating the aramid fibers. The air inside the drying chamber is extracted by the vacuum pump to prevent excessive air pressure and is discharged into the air storage shell and then discharged through the air duct to maintain the air pressure inside the drying chamber.
[0033] 5. This invention uses a drive motor to drive a drive rod, causing a rotating plate to rotate, thereby pushing and limiting the aramid fibers. The angle of the rotating plate is adjusted according to the tightness of the aramid fibers, thus limiting and pressing the aramid fibers to prevent them from becoming loose, resulting in accumulation or entanglement, which would affect the cleanliness of the cleaning and prevent complete drying. The fibers would also easily attract dust and impurities during transportation. A rubber pad is bonded to the contact surface between the rotating plate and the aramid fibers to prevent excessive compression that could damage the surface of the aramid fibers.

[0042] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0043] Please refer to Figure 1-2 A fiber cleaning and drying system for the production process of aramid UD fabric includes a cleaning box 1, with feeding ports 3 on both sides of the outer wall of the cleaning box 1. A drying box 2 is located at the feeding port 3 on one side of the outer wall of the cleaning box 1, and a winding device body 4 is detachably connected to the feeding port 3 on the other side of the outer wall of the cleaning box 1 via bolts. Door panels 5 are embedded at the front ends of both the cleaning box 1 and the drying box 2. A feeding mechanism 6 is fixed at the lower interior of the cleaning box 1, and a cleaning mechanism 7 is located above the feeding mechanism 6 inside the cleaning box 1. Triangular cross-section guide blocks 8 are fixed on both sides of the bottom end of the cleaning box 1. A solenoid valve 9 extends from the bottom end of the cleaning box 1. Three second transmission cylinders 10 are installed inside the drying box 2. A drying mechanism 11 is located at the top of the drying box 2. An adjustment mechanism 12 is located on the side of the drying box 2 closest to the feeding port 3 away from the cleaning box 1. An ultrasonic generator 13 is embedded below the front door panel 5 of the cleaning box 1.
[0044] In use, the aramid fibers are transported through the two sets of winding equipment 4 into the cleaning box 1 and the drying box 2. In the cleaning box 1, the aramid fibers are tensioned by the conveying mechanism 6 to prevent loosening and tangling that could lead to accumulation and affect the cleaning quality. The aramid fibers are then rinsed while being soaked by the cleaning mechanism 7 to further improve the cleaning quality and prevent impurities from remaining. After cleaning, the aramid fibers enter the drying box 2, where they are supported by three triangular second conveying cylinders 10 and transported. At the same time, the aramid fibers are unfolded to facilitate drying by the drying mechanism 11. The aramid fibers soaked in the cleaning box 1 are cleaned by the ultrasonic generator 13, and the ultrasonic cleaning greatly improves the cleaning and impurity removal effect.
[0045] The material conveying mechanism 6 includes a support plate 601, which is inclined and fixedly placed on one side of the inner wall of the cleaning tank 1. The two ends of the support plate 601 are rotatably connected to a first transmission cylinder 602. The inner wall of the cleaning tank 1 is rotatably connected to a traction roller 603 located below the lower side of the support plate 601, and a limit collar 604 is fixed on the outer wall of the traction roller 603.
[0046] In use, the cleaning box 1 is closed by opening and closing the door panel 5 to adjust and place the aramid fibers, and at the same time, the cleaning solution is injected until the traction roller 603 is submerged. Two sets of support plates 601 are provided to limit and fit the aramid fibers, and to provide a certain tension to prevent loosening. The first transmission cylinder 602 is embedded at both ends of the support plate 601 to improve the smoothness of the aramid fiber transmission and avoid excessive friction that could damage the surface of the aramid fibers. The traction roller 603 facilitates the aramid fibers to enter the cleaning solution for soaking during transmission.
[0047] Reference Figure 1 , Figure 2 and Figure 4 The cleaning mechanism 7 includes a through hole 702, which is located below the rear end of the cleaning tank 1. A conveying pipe 703 extends through the through hole 702. One end of the conveying pipe 703 is connected to a pump 701. Another set of conveying pipes 703 extending from the other end of the pump 701 is connected to a conveying hose 704. The two conveying hoses 704 are respectively connected to corresponding water spray pipes 705. Multiple water spray holes 706 are evenly spaced on the outer wall of the support plate 601.
[0048] In addition, the cleaning mechanism 7 also includes a miniature electric push rod 707, which is fixedly installed on the inner wall of the cleaning tank 1 at one end of the water spray pipe 705. A damping spring 708 is fixedly installed at the end of the water spray pipe 705 away from the miniature electric push rod 707. The pump 701 is connected to the cleaning tank 1 through the delivery pipe 703. The delivery pipe 703 is connected to the water spray pipe 705 through the delivery hose 704. At the same time, the water spray pipe 705 is elastically connected to the cleaning tank 1 through the damping spring 708.
[0049] In use, the pump 701 recycles the cleaning solution inside the cleaning tank 1 through the delivery pipe 703 to avoid waste. The pump 701 delivers the cleaning solution to the delivery hose 704 through the delivery pipe 703, and then into the spray pipe 705 and sprays it out through the spray hole 706. The spray hole 706 is aimed at the aramid fibers on the support plate 601, so as to better rinse them and prevent the aramid fibers from bending or shaking due to the impact, which would result in incomplete rinsing. In addition, the spray pipe 705 is pushed to reciprocate by the micro electric push rod 707. The spray pipe 705 is elastically contracted by the damping spring 708, which makes the spray pipe 705 shock-absorbing when it shakes. The spray pipe 705 drives the sprayed water to shake along the aramid fibers, so as to better rinse the gaps between the fibers.
[0050] Reference Figure 1 and Figure 5 The drying mechanism 11 includes a temperature-controlled hot air blower body 1101, which is fixedly installed on one side of the top of the drying chamber 2. A filter screen 1102 is embedded in the outer wall of the top of the temperature-controlled hot air blower body 1101, and an air supply pipe 1103 connects the temperature-controlled hot air blower body 1101 and the drying chamber 2.
[0051] Meanwhile, the drying mechanism 11 also includes a vacuum pump 1104, which is embedded in both sides of the bottom of the drying chamber 2. A gas storage shell 1105 is fixedly installed at the bottom of the drying chamber 2 corresponding to the position of the vacuum pump 1104. A reserved hole 1106 is opened at the bottom of the interior of the gas storage shell 1105, and an air inlet pipe 1107 is inserted into the reserved hole 1106. The air inlet pipe 1107 communicates with the drying chamber 2 through the vacuum pump 1104 and the gas storage shell 1105. The main body 1101 of the temperature-controlled hot air blower is detachably connected to the filter screen 1102 by bolts.
[0052] In use, the main body 1101 of the temperature-controlled hot air blower delivers hot air through the air supply pipe 1103 into the drying chamber 2 to dry the aramid fibers. The filter screen 1102 prevents dust and impurities from entering the air absorbed by the main body 1101 of the temperature-controlled hot air blower and contaminating the aramid fibers. The vacuum pump 1104 extracts the air from the drying chamber 2 to prevent excessive air pressure and discharges it into the air storage shell 1105 and out through the air duct 1107 to maintain the air pressure inside the drying chamber 2.
[0053] Reference Figure 1 and Figure 6 The adjustment mechanism 12 includes a drive motor 1201, which is embedded in the outer wall of the drying box 2 near the main body 4 of the winding equipment. The power output end of the drive motor 1201 is connected to a drive rod 1202. A rotating plate 1203 is fixed to the outside of the drive rod 1202. A rubber pad 1204 is connected to the end of the rotating plate 1203 away from the drive rod 1202. The rotating plate 1203 forms a rotating structure with the drive rod 1202 and the drive motor 1201. The rotating plate 1203 and the rubber pad 1204 are bonded together.
[0054] In use, the drive motor 1201 drives the drive rod 1202, causing the rotating plate 1203 to rotate, thereby pushing and limiting the aramid fibers. The angle of the rotating plate 1203 is adjusted according to the tightness of the aramid fibers, thereby limiting and pressing the aramid fibers to prevent them from becoming loose, resulting in stacking or tangling, which would affect the cleanliness of the cleaning, prevent complete drying, and make them prone to adsorbing dust and impurities during transportation. At the same time, a rubber pad 1204 is bonded to the contact surface between the rotating plate 1203 and the aramid fibers to prevent excessive pressing from damaging the surface of the aramid fibers.
[0055] The implementation principle of this invention is as follows: The outer walls of the cleaning tank 1 are provided with feeding ports 3 on both sides, which are connected to the drying tank 2 for immediate drying after cleaning, preventing the adsorption of external dust and thus avoiding contamination that could affect the impregnation process. A feeding port 3 is opened on the side of the drying tank 2 away from the cleaning tank 1. A winding device body 4 is provided on the other side of the feeding port 3 in the cleaning tank 1 and on the side of the feeding port 3 in the drying tank 2, facilitating the winding of aramid fibers. Door panels 5 are provided at the front of both the cleaning tank 1 and the drying tank 2 for easy maintenance of internal components or placement and adjustment of aramid fibers. After opening the door panel 5, the cleaning solution is injected into the cleaning tank 1. The aramid fibers entering the cleaning tank 1 are attached to the support plate 601 of the conveying mechanism 6 and straightened by the traction roller 603 to prevent loosening. The traction roller 603 is located in the cleaning solution to facilitate the soaking and cleaning of the aramid fibers. The cleaning tank 1 is equipped with a water temperature control device to control and maintain the temperature of the internal cleaning solution. At the same time, the ultrasonic generator 13 (model PLS-DLB-200W) embedded in the cleaning tank 1 is used to improve the cleaning effect and prevent impurities from being difficult to remove. The support plate 601 is fixed inside the cleaning tank 1, and the first transmission cylinder 602 is provided at both ends to improve the smooth conveying of the aramid fibers.
[0056] A limiting collar 604 is fixed outside the traction roller 603 to prevent the aramid fibers from shifting during transmission. The pump 701 of the cleaning mechanism 7 operates, drawing cleaning solution from inside the cleaning tank 1 through the through hole 702 via the conveying pipe 703. This solution is then conveyed to the conveying hose 704 via another set of conveying pipes 703 and sprayed out through the spray holes 706 of the spray pipe 705. Two sets of spray pipes 705 are provided to rinse the aramid fibers on the support plate 601 at two angles, improving the cleaning effect. Two support plates 601 are also provided. 1. No water spray pipe 705 is installed at the discharge port 3 to avoid the cleaning solvent containing debris from re-contaminating the cleaned aramid fibers. A miniature electric push rod 707 is installed at one end of each of the two sets of water spray pipes 705, and a damping spring 708 is installed at the other end. The miniature electric push rod 707 facilitates the movement of the water spray pipe 705, so that it can sway left and right during rinsing, which can rinse the aramid fibers in the gaps or layers, improving the cleanliness. At the same time, the damping spring 708 provides shock absorption while the water spray pipe 705 moves due to elastic contraction.
[0057] Secondly, the cleaning solution after cleaning is discharged through solenoid valve 9 and guided by guide block 8 to avoid water accumulation. Three second transmission cylinders 10 are arranged in a triangular pattern inside the drying chamber 2 to maintain tension on the aramid fibers and facilitate the drying process. The main body 1101 of the temperature-controlled hot air blower (model Vanke NFJ-886, customizable to actual dimensions) of the drying mechanism 11 is fixed at the top of the drying chamber 2. Air is blown into the drying chamber 2 through air pipe 1103 to dry the aramid fibers, preventing them from absorbing dust and impurities after cleaning, which would affect subsequent processing. A filter screen 1102 is installed at the top inlet of the temperature-controlled hot air blower 1101 to prevent dust and impurities from entering. Vacuum pumps 1104 are embedded on both sides of the bottom of the drying chamber 2 to extract internal hot air and guide it into the air storage shell 1105. The air intake pipe 1107 passes through the reserved hole 1106 into the air storage shell 1105 to facilitate the exhaust of air and prevent excessive internal air pressure from affecting the operation. The drive motor 1201 of the adjustment mechanism 12 is embedded on the outer wall of the drying box 2 near the feed port 3 of the main body of the winding equipment 4. The drive motor 1201 drives the drive rod 1202 to rotate. The bearing sleeve on the end of the drive rod 1202 away from the drive motor 1201 is bolted to the inner wall of the drying box 2, so that the drive rod 1202 can drive the rotating plate 1203 to rotate and adjust the angle. The angle can be adjusted according to the looseness of the aramid fiber to increase the tension and prevent it from being too loose and causing entanglement, which makes it difficult to clean impurities and dust. A rubber pad 1204 is bonded to the contact surface between the rotating plate 1203 and the aramid fiber to prevent excessive compression from damaging the outer wall surface of the aramid fiber.
[0058] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
