Abstract

This invention belongs to the field of polyethylene fiber processing technology, specifically a coating device and method for ultra-high molecular weight polyethylene fibers. Addressing the problems of uneven coating of slurry on both sides of the fabric, inability to scrape off excess slurry, slurry sedimentation in the storage tank, and slurry waste in existing technologies, the present invention proposes the following solution: A housing with an inlet and an outlet on one side, the outlet being located above the inlet; a conveying assembly housed within the housing for conveying and winding the fabric; and a coating assembly housed within the housing. This invention enables simultaneous coating of both sides of the fabric, avoiding the uneven coating caused by single-sided coating. Furthermore, after coating, excess slurry on both sides of the fabric can be scraped off, ensuring the smoothness of the fabric. Additionally, during the coating and scraping process, dripping slurry can be recycled, preventing slurry waste.

Description

Technical Field

[0001] This invention relates to the field of polyethylene fiber processing technology, and in particular to an ultra-high molecular weight polyethylene fiber coating device and its application method. Background Technology

[0002] Ultra-high molecular weight polyethylene (UHMWPE) fiber, also known as high-strength, high-modulus polyethylene fiber, has a regular, symmetrical molecular structure. Its non-polar and extended chain structures give it excellent chemical inertness, hydrophobicity, and extremely high surface crystallinity. Therefore, this fiber does not readily react with other substances, and dyes cannot penetrate its interior. Polyethylene fiber is widely used in bulletproof vests and helmets, lightweight armor, sails, cables, fiber optic cable reinforcements, parachutes, and filter materials.

[0003] For example, when coating sails with polyethylene fibers, a rotating roller is often used to coat the fabric. For instance, utility models with announcement numbers CN216585599U and CN114214798A coat one side of the fabric with a rotating roller, allowing the polyethylene fiber slurry to penetrate the fabric and thus complete the overall coating of the fabric.

[0004] However, the existing technology still has the following shortcomings:

[0005] 1. Although the above technical solution achieves the purpose of overall coating by coating one side of the fabric by rotating the roller, the coating process results in uneven coating of the slurry on both sides of the fabric due to the sufficient amount of slurry on one side and the thin amount of slurry on the other side.

[0006] 2. When the coating of the fabric is finished, it is not possible to scrape off the excess paste on the fabric so that the paste can be evenly applied to the fabric. As a result, after the fabric and paste are dried, the surface of the fabric will be uneven, which will affect the appearance of the fabric.

[0007] 3. When the coating of the fabric is finished, the slurry is stored in the storage tank. Since the slurry is mostly applied to the fabric at a uniform and slow speed, it is easy for the slurry to settle in the storage tank over time, which will affect the quality of the subsequent fabric coating.

[0008] 4. When the coating of the fabric is finished, excess slurry drips from the rotating roller, resulting in slurry waste.

[0009] To address the above-mentioned problems, this invention proposes an ultra-high molecular weight polyethylene fiber coating device and its usage method. Summary of the Invention

[0010] This invention provides an ultra-high molecular weight polyethylene fiber coating device and its usage method, which solves the shortcomings of the prior art, such as uneven coating of slurry on both sides of the fabric, inability to scrape off excess slurry on the fabric, sedimentation of slurry in the storage tank, and waste of slurry.

[0011] This invention provides the following technical solution:

[0012] An ultra-high molecular weight polyethylene fiber coating device, comprising:

[0013] The outer casing has an inlet and an outlet on one side, with the outlet located above the inlet.

[0014] The conveying assembly, housed within the housing, is used for conveying and winding the fabric.

[0015] A coating assembly, housed within the housing, is used to coat both sides of the fabric.

[0016] The scraping component, located inside the housing, is used to scrape off the coated fabric to ensure the smoothness of the fabric after drying.

[0017] The stirring assembly is located inside the outer casing to prevent sedimentation of the slurry.

[0018] In one possible design, the conveying assembly includes a first conveying roller rotatably connected within a housing, two guide rollers rotatably connected from top to bottom within the housing, and a take-up roller for winding the fabric rotatably connected via a rectangular plate on the side of the housing near the discharge port.

[0019] In one possible design, the coating assembly includes a trapezoidal coating plate fixedly connected within a housing. The bottom of the trapezoidal coating plate is lower than the top of a first conveying roller and lower than the bottom of a guide roller located below. Multiple sliding rods slide through the trapezoidal coating plate. A fixed plate is fixedly connected to the top of each sliding rod. A first spring, fixedly connected to the bottom of the fixed plate, is fitted onto the outer wall of each sliding rod, and its bottom end is fixedly connected to the top of the trapezoidal coating plate. The bottom ends of the multiple sliding rods slide through the trapezoidal coating plate and are fixedly connected to the same collection box. Multiple coating rollers for coating the lower layer of the fabric are rotatably connected within the collection box. A liquid storage tank located above the trapezoidal coating plate is fixedly connected within the housing. A connecting pipe is fixedly connected to the bottom of the liquid storage tank. An electromagnetic flow valve is fixedly fitted onto the outer wall of the connecting pipe. A conduit is fixedly connected to the bottom of the connecting pipe, and multiple slurry outlet pipes are fixedly connected to the bottom of the conduit, with the slurry outlet pipes located on the side of the trapezoidal coating plate closest to the first conveying roller.

[0020] In one possible design, the scraping assembly includes a fixed plate fixedly connected inside a housing, a sliding plate slidably connected inside the housing, the bottom of the fixed plate and the top of the sliding plate being elastically connected by multiple tension springs, and an upper scraping block and a lower scraping block for scraping off the surface slurry of the fabric being fixedly connected to the bottom of the fixed plate and the top of the sliding plate, respectively.

[0021] In one possible design, the stirring assembly includes a rotating shaft rotatably connected within a housing, positioned between two guide rollers. Multiple rubber wheels are fixedly fitted onto the outer wall of the rotating shaft, with the outer walls of the rubber wheels contacting the outer walls of the two guide rollers. Multiple triangular push blocks are fixedly connected to the outer wall of the rotating shaft. A support plate is fixedly connected within the housing. A trapezoidal rod, cooperating with the triangular push blocks, slides through the support plate. A stop block is fixedly fitted onto the outer wall of the trapezoidal rod. A second spring, fixedly connected to the stop block, is fitted onto the outer wall of the trapezoidal rod. The end of the second spring away from the stop block is fixedly connected to a storage tank. The end of the trapezoidal rod away from the rotating shaft slides into the storage tank and is fixedly connected to a push plate, which is slidably connected to the bottom inner wall of the storage tank.

[0022] In one possible design, two bases are fixedly connected to the side of the outer casing near the discharge port. A rotating shaft is rotatably connected to the side of the two bases that are close to each other. A U-shaped frame is fixedly fitted on the outer wall of the rotating shaft. A guide wheel that contacts the fabric being wound on the outer wall of the take-up roller is rotatably fitted on the outer wall of the U-shaped frame. Two torsion springs are fitted on the outer wall of the rotating shaft. The ends of the two torsion springs that are far apart from each other are fixedly connected to the bases, and the ends of the two torsion springs that are close to each other are fixedly connected to the U-shaped frame. The torsion force of the torsion springs can cause the U-shaped frame to drive the guide wheel to rotate downward, so that the guide wheel contacts the fabric being wound on the outer wall of the take-up roller. This makes the take-up roller wind the fabric more smoothly and avoids wrinkles on the take-up roller.

[0023] In one possible design, a liquid pump is fixedly connected to one side of the housing. The inlet of the liquid pump is fitted with a first hose, one end of which extends into the collection tank. The outlet of the liquid pump is fitted with a second hose, one end of which extends into the storage tank. When the slurry collected in the collection tank is about to overflow, the liquid pump is started. The liquid pump guides the slurry collected in the collection tank into the storage tank through the first hose and the second hose, preventing the slurry in the collection tank from overflowing and causing waste.

[0024] In one possible design, the upper scraper has a first liquid guiding groove on the side near the guide roller, and the sliding plate has second liquid guiding grooves on both sides. The outer wall of the first conveying roller is fixedly fitted with two threaded protrusions, which are in opposite directions. When the upper scraper scrapes the upper layer of the fabric, the scraped slurry flows into the first liquid guiding groove, is guided by the first liquid guiding groove to flow to both sides and drips onto the sliding plate. When the lower scraper scrapes the lower layer of the fabric, the slurry flows onto the sliding plate, and the slurry on the sliding plate is guided by the second liquid guiding groove into the storage tank. This not only scrapes both sides of the fabric to ensure its flatness, but also allows for the recycling of the scraped slurry, reducing resource waste. When the first conveying roller rotates to convey the fabric, the two oppositely oriented threaded protrusions on the outer wall of the first conveying roller can allow the fabric to expand and lay flat, preventing the fabric from piling up or wrinkling during the conveying process.

[0025] In one possible design, an upper drying chamber and a lower drying chamber are fixedly connected inside the outer casing, with the upper and lower drying chambers located above and below the fabric, respectively. Multiple resistance wire heating elements are fixedly connected to the inner walls of the upper and lower drying chambers on opposite sides. A blower is fixedly connected to the top of the upper drying chamber, and the air outlet of the upper drying chamber extends into the chamber. A guide plate located below the fabric is fixedly connected inside the outer casing, with the side of the guide plate away from the material guide roller fixedly connected to the lower drying chamber. A vent is provided on the side of the lower drying chamber near the guide plate. When the resistance wire heating elements and the blower are activated, the blower blows the heated air from the upper drying chamber downwards, drying the upper layer of the fabric. As the hot air moves downwards through the fabric, it is guided by the guide plate and flows into the lower drying chamber. The hot air in the lower drying chamber then rises upwards to dry the lower layer of the fabric, completing the double-sided drying task.

[0026] The method of using the ultra-high molecular weight polyethylene fiber coating device includes the following steps:

[0027] S1. The winding roller, the first conveying roller, and the guiding roller are driven by motors to rotate (the motors are not shown in the diagram). The first conveying roller and the guiding roller convey the fabric, and the winding roller winds up the fabric after coating. The electromagnetic flow valve is activated, and the polyethylene fiber slurry in the storage tank drips onto the fabric through the connecting pipe, the guide pipe, and the slurry outlet pipe. Since the bottom of the trapezoidal coating plate is lower than the top of the first conveying roller, the slurry dripping onto the fabric flows towards the trapezoidal coating plate. As the first conveying roller and the guiding roller convey the fabric, the trapezoidal coating plate comes into contact with the slurry. The trapezoidal coating plate and the slurry work together to coat the upper layer of the fabric. During the coating process, the slurry flows along the two inclined surfaces of the trapezoidal coating plate and drips from the fabric into the collection box.

[0028] S2. Due to the elastic force of the first spring, the first spring pushes the sliding rod and the fixed plate to move upward. The sliding rod drives the collection box to move upward, thereby clamping the fabric through the coating roller and the trapezoidal coating plate. During the fabric conveying process, the fabric drives the coating roller to rotate, and the bottom of the coating roller is immersed in the slurry in the collection box. As the coating roller rotates, the coating roller can coat the bottom of the fabric, thereby coating both sides of the fabric at the same time, and avoiding the waste of slurry dripping from the fabric.

[0029] S3. After being guided and conveyed by the feed roller, the coated fabric passes between the fixed plate and the sliding plate. The tension of the spring allows the fixed plate and the sliding plate to clamp the fabric, thereby causing the upper and lower scraper blocks to scrape off the slurry from the upper and lower layers of the fabric. When the upper scraper block scrapes off the upper layer of the fabric, the scraped slurry flows onto the upper scraper block and is guided to flow to both sides and drip onto the sliding plate. When the lower scraper block scrapes off the lower layer of the fabric, the slurry flows onto the sliding plate. The slurry on the sliding plate is guided into the storage tank through the second liquid guide groove. This process not only scrapes off both sides of the fabric to ensure its flatness, but also allows for the recycling of the scraped slurry, reducing resource waste.

[0030] S4. When the two guide rollers rotate clockwise to convey the fabric, the friction between the guide rollers and the rubber wheels causes the rotating shaft and the triangular push block to rotate counterclockwise. The inclined surface of the triangular push block contacts the inclined surface of the trapezoidal rod, which in turn pushes the trapezoidal rod, the stop block, and the push plate to move to the right. The second spring begins to compress. When the triangular push block disengages from the trapezoidal rod, the trapezoidal rod and the push plate return to their original positions under the elastic force of the second spring. As the rotating shaft and the triangular push block rotate, the push plate can move back and forth in the storage tank, stirring the slurry in the storage tank and preventing sedimentation.

[0031] S5. When the slurry collected in the collection box is about to overflow, start the pump. The pump will guide the slurry collected in the collection box into the storage tank through the first hose and the second hose to prevent the slurry in the collection box from overflowing and causing waste. In addition, start the resistance wire heating element and the blower. The blower blows the heated air in the upper drying box downwards. The hot air can dry the upper layer of the fabric. When the hot air moves downwards through the fabric, it is guided by the air guide plate and flows into the lower drying box. Then the hot air in the lower drying box rises to dry the lower layer of the fabric, completing the double-sided drying task of the fabric.

[0032] S6. The take-up roller rotates to complete the take-up of the dried fabric. As the take-up roller takes up its length, the thickness of the fabric on the outer wall of the take-up roller gradually increases. Under the torsion of the torsion spring, the U-shaped frame tightly contacts the guide roller with the fabric on the outer wall of the take-up roller, which makes the take-up roller take up the fabric more smoothly and avoids wrinkles on the take-up roller.

[0033] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0034] In this invention, multiple sliding rods slide through the trapezoidal coating plate. A fixed plate is fixedly connected to the top of each sliding rod. A first spring is sleeved on the outer wall of each sliding rod and fixedly connected to the bottom of the fixed plate. The bottom end of the first spring is fixedly connected to the top of the trapezoidal coating plate. A collection box is fixedly connected to the bottom of each sliding rod. Multiple coating rollers are rotatably connected inside the collection box. Under the elastic force of the first spring, the coating rollers and the trapezoidal coating plate clamp the fabric. During the fabric conveying process, the fabric drives the coating rollers to rotate, and the bottom of the coating rollers is immersed in the slurry in the collection box. As the coating rollers rotate, they can coat the bottom of the fabric, thereby coating both sides of the fabric simultaneously and avoiding waste of slurry dripping from the fabric.

[0035] In this invention, a trapezoidal coating plate is fixedly connected inside the outer shell, and the bottom of the trapezoidal coating plate is lower than the top of the first conveying roller. Polyethylene fiber slurry in the storage tank drips onto the fabric, and the slurry on the fabric flows towards the trapezoidal coating plate. As the first conveying roller and the guide roller convey the fabric, the trapezoidal coating plate comes into contact with the slurry. The trapezoidal coating plate and the slurry work together to coat the upper layer of the fabric. During the coating process, the slurry flows along the two inclined surfaces of the trapezoidal coating plate. The slurry drips from the fabric into the collection box. The collection box can not only recover the slurry but also coat the lower layer of the fabric through the coating roller. Thus, both sides of the fabric can be coated simultaneously, and the waste of slurry dripping from the fabric is avoided.

[0036] In this invention, multiple rubber wheels are fixedly sleeved on the outer wall of the rotating shaft, and multiple triangular push blocks are fixedly sleeved on the outer wall of the rotating shaft. A trapezoidal rod that cooperates with the triangular push blocks slides through the support plate. The end of the trapezoidal rod away from the rotating shaft slides into the storage tank and is fixedly connected to a push plate. The friction between the guide roller and the rubber wheels causes the rotating shaft to rotate counterclockwise. The triangular push blocks cooperate with the trapezoidal rod to push the trapezoidal rod and the push plate to move to the right. As the rotating shaft and the triangular push blocks rotate, the push plate can move back and forth in the storage tank to stir the slurry in the storage tank and prevent the slurry from settling.

[0037] In this invention, a fixed plate is fixedly connected inside the outer shell, and a sliding plate is slidably connected inside the outer shell. The bottom of the fixed plate and the top of the sliding plate are elastically connected by multiple tension springs. An upper scraping block and a lower scraping block for scraping off the surface slurry of the fabric are fixedly connected to the bottom of the fixed plate and the top of the sliding plate, respectively. The tension of the tension springs allows the fixed plate and the sliding plate to clamp the fabric, thereby causing the upper and lower scraping blocks to scrape off the slurry on the upper and lower layers of the fabric. The scraped slurry flows into the storage tank through the second liquid guide groove. This not only scrapes off both sides of the fabric to ensure its flatness and aesthetics, but also allows the scraped slurry to be recycled, reducing resource waste.

[0038] In this invention, both sides of the fabric can be coated simultaneously, avoiding uneven coating caused by single-sided coating. In addition, after coating, excess slurry on both sides of the fabric can be scraped off to ensure the smoothness of the fabric. Furthermore, during the coating and scraping process, dripping slurry can be recycled to avoid slurry waste and increased coating costs. When the guide roller is conveying, it drives the rotating shaft and triangular push block to rotate, causing the push plate to stir the slurry in the storage tank and prevent slurry sedimentation.

[0056] Example 1

[0057] Reference Figure 1 , Figure 2 and Figure 8This embodiment of an ultra-high molecular weight polyethylene fiber coating device includes: a housing 1, with an inlet 2 and an outlet 3 on one side of the housing 1, the outlet 3 being located above the inlet 2; a conveying assembly, disposed inside the housing 1, for conveying and winding the fabric; a coating assembly, disposed inside the housing 1, for coating both sides of the fabric; a scraping assembly, disposed inside the housing 1, for scraping the coated fabric to ensure the smoothness of the fabric after drying; and a stirring assembly, disposed inside the housing 1, for preventing sedimentation of the slurry. Two bases 23 are bolted to the side of the housing 1 near the outlet 3, with the two bases 23 close to each other. A rotating shaft 24 is connected to the side. A U-shaped frame 25 is fixedly sleeved on the outer wall of the rotating shaft 24. A guide wheel 27 is rotatably sleeved on the outer wall of the U-shaped frame 25, which contacts the fabric being wound on the outer wall of the take-up roller 22. Two torsion springs 26 are sleeved on the outer wall of the rotating shaft 24. The ends of the two torsion springs 26 that are far apart from each other are fixedly connected to the base 23, and the ends of the two torsion springs 26 that are close to each other are fixedly connected to the U-shaped frame 25. The torsion force of the torsion springs 26 can cause the U-shaped frame 25 to drive the guide wheel 27 to rotate downward, so that the guide wheel 27 contacts the fabric being wound on the outer wall of the take-up roller 22. This makes the take-up roller 22 wind up the fabric more smoothly and avoids wrinkles on the take-up roller 22.

[0058] Reference Figure 1 and Figure 2 The conveying assembly includes a first conveying roller 4 rotatably connected inside the housing 1. Two guide rollers 5 are rotatably connected from top to bottom inside the housing 1. A winding roller 22 for winding the fabric is rotatably connected to the side of the housing 1 near the discharge port 3 via a rectangular plate.

[0059] Reference Figure 3 and Figure 4The coating assembly includes a trapezoidal coating plate 6 bolted to the housing 1. The bottom of the trapezoidal coating plate 6 is lower than the top of the first conveying roller 4 and the bottom of the guide roller 5 located below it. Multiple sliding rods 9 slide through the trapezoidal coating plate 6. A fixed plate 10 is bolted to the top of each sliding rod 9. A first spring 11, fixedly connected to the bottom of the fixed plate 10, is sleeved on the outer wall of each sliding rod 9. The bottom end of the first spring 11 is fixedly connected to the top of the trapezoidal coating plate 6. The bottom ends of the multiple sliding rods 9 slide... A collection box 7 is bolted through the trapezoidal coating plate 6. Multiple coating rollers 8 for coating the lower layer of the fabric are rotatably connected inside the collection box 7. A liquid storage tank 12, located above the trapezoidal coating plate 6, is fixedly connected inside the outer shell 1. A connecting pipe 13 is bolted to the bottom of the liquid storage tank 12. An electromagnetic flow valve 14 is fixedly fitted onto the outer wall of the connecting pipe 13. A conduit 15 is bolted to the bottom of the connecting pipe 13. Multiple slurry outlet pipes 16 are bolted to the bottom of the conduit 15, and the slurry outlet pipes 16 are located within the trapezoidal... The coating plate 6 is located near the first conveying roller 4. Under the elastic force of the first spring 11, the coating roller 8 and the trapezoidal coating plate 6 clamp the fabric. During fabric conveying, the fabric drives the coating roller 8 to rotate, while the bottom of the coating roller 8 is immersed in the slurry in the collection box 7. As the coating roller 8 rotates, it can coat the bottom of the fabric, thus coating both sides of the fabric simultaneously. The bottom of the trapezoidal coating plate 6 is lower than the top of the first conveying roller 4. Polyethylene fiber slurry in the storage tank 12 drips onto the fabric, and the slurry on the fabric... The liquid flows towards the trapezoidal coating plate 6. As the first conveying roller 4 and the guide roller 5 convey the fabric, the trapezoidal coating plate 6 comes into contact with the slurry. The trapezoidal coating plate 6 and the slurry work together to coat the upper layer of the fabric. During the coating process, the slurry flows along the two inclined surfaces of the trapezoidal coating plate 6. The slurry drips from the fabric into the collection box 7. The collection box 7 can not only recover the slurry but also coat the lower layer of the fabric through the coating roller 8. Thus, both sides of the fabric can be coated at the same time, and the slurry dripping from the fabric is not wasted.

[0060] Reference Figure 6The scraping assembly includes a fixed plate 17 bolted to the housing 1, a sliding plate 18 slidably connected inside the housing 1, and a bottom of the fixed plate 17 and a top of the sliding plate 18 elastically connected by multiple tension springs 19. An upper scraper 20 and a lower scraper 21 for scraping the surface slurry of the fabric are bolted to the bottom of the fixed plate 17 and the top of the sliding plate 18, respectively. The tension of the tension springs 19 allows the fixed plate 17 and the sliding plate 18 to clamp the fabric, thereby allowing the upper scraper 20 and the lower scraper 21 to scrape the slurry from the upper and lower layers of the fabric. The scraped slurry flows into the storage tank 12 through the second liquid guide trough 40. This not only scrapes both sides of the fabric to ensure its flatness and aesthetics, but also allows for the recycling of the scraped slurry, reducing resource waste.

[0061] Reference Figure 5 The mixing assembly includes a rotating shaft 28 rotatably connected within the outer casing 1, positioned between two guide rollers 5. Multiple rubber wheels 29 are fixedly fitted onto the outer wall of the rotating shaft 28, and the outer walls of the rubber wheels 29 contact the outer walls of the two guide rollers 5. Multiple triangular push blocks 30 are bolted to the outer wall of the rotating shaft 28. A support plate 31 is bolted to the inner casing 1. A trapezoidal rod 32, cooperating with the triangular push blocks 30, slides through the support plate 31. A stop block 34 is fixedly fitted onto the outer wall of the trapezoidal rod 32, and a second spring 35 is fixedly connected to the stop block 34. One end of the rod away from the stop block 34 is fixedly connected to the storage tank 12. The end of the trapezoidal rod 32 away from the rotating shaft 28 extends slidably into the storage tank 12 and is fixedly connected to the push plate 33 by bolts. The push plate 33 is slidably connected to the bottom inner wall of the storage tank 12. The friction between the guide roller 5 and the rubber wheel 29 drives the rotating shaft 28 to rotate counterclockwise. The triangular push block 30 cooperates with the trapezoidal rod 32 and can push the trapezoidal rod 32 and the push plate 33 to the right. As the rotating shaft 28 and the triangular push block 30 rotate, they can drive the push plate 33 to move back and forth in the storage tank 12, stirring the slurry in the storage tank 12 and preventing the slurry from settling.

[0062] Reference Figure 3 A liquid pump 37 is fixedly connected to one side of the outer casing 1 by bolts. The inlet of the liquid pump 37 is fixedly fitted with a first hose 36, and one end of the first hose 36 extends into the collection tank 7. The outlet of the liquid pump 37 is fixedly fitted with a second hose 38, and one end of the second hose 38 extends into the storage tank 12. When the slurry collected in the collection tank 7 is about to overflow, the liquid pump 37 is started. The liquid pump 37 guides the slurry collected in the collection tank 7 into the storage tank 12 through the first hose 36 and the second hose 38 to prevent the slurry in the collection tank 7 from overflowing and causing waste.

[0063] Reference Figure 6 , Figure 7 and Figure 9 The upper scraper 20 has a first liquid guiding groove 39 on one side near the guide roller 5, and the sliding plate 18 has a second liquid guiding groove 40 on both sides. The outer wall of the first conveying roller 4 is fixedly fitted with two threaded protrusions 41, and the two threaded protrusions 41 are in opposite directions. When the upper scraper 20 scrapes the upper layer of the fabric, the scraped slurry flows into the first liquid guiding groove 39, and flows to both sides through the guidance of the first liquid guiding groove 39 and drips onto the sliding plate 18. When the lower scraper 21 scrapes the lower layer of the fabric, the slurry flows to the sliding plate 18. On plate 18, the slurry on sliding plate 18 flows into storage tank 12 through the second liquid guide groove 40. This not only scrapes off both sides of the fabric to ensure its flatness, but also allows the scraped slurry to be recycled, reducing resource waste. When the first conveying roller 4 rotates to convey the fabric, the two oppositely oriented threaded protrusions 41 on the outer wall of the first conveying roller 4 can make the fabric stretch and lay flat, preventing the fabric from piling up or wrinkling during the conveying process.

[0065] Reference Figure 1 , Figure 2 and Figure 8 This embodiment of an ultra-high molecular weight polyethylene fiber coating device includes: a housing 1, with an inlet 2 and an outlet 3 on one side of the housing 1, the outlet 3 being located above the inlet 2; a conveying assembly, disposed inside the housing 1, for conveying and winding the fabric; a coating assembly, disposed inside the housing 1, for coating both sides of the fabric; a scraping assembly, disposed inside the housing 1, for scraping the coated fabric to ensure the smoothness of the fabric after drying; and a stirring assembly, disposed inside the housing 1, for preventing sedimentation of the slurry. Two bases 23 are bolted to the side of the housing 1 near the outlet 3, with the two bases 23 close to each other. A rotating shaft 24 is connected to the side. A U-shaped frame 25 is fixedly sleeved on the outer wall of the rotating shaft 24. A guide wheel 27 is rotatably sleeved on the outer wall of the U-shaped frame 25, which contacts the fabric being wound on the outer wall of the take-up roller 22. Two torsion springs 26 are sleeved on the outer wall of the rotating shaft 24. The ends of the two torsion springs 26 that are far apart from each other are fixedly connected to the base 23, and the ends of the two torsion springs 26 that are close to each other are fixedly connected to the U-shaped frame 25. The torsion force of the torsion springs 26 can cause the U-shaped frame 25 to drive the guide wheel 27 to rotate downward, so that the guide wheel 27 contacts the fabric being wound on the outer wall of the take-up roller 22. This makes the take-up roller 22 wind up the fabric more smoothly and avoids wrinkles on the take-up roller 22.

[0066] Reference Figure 1 and Figure 2The conveying assembly includes a first conveying roller 4 rotatably connected inside the housing 1. Two guide rollers 5 are rotatably connected from top to bottom inside the housing 1. A winding roller 22 for winding the fabric is rotatably connected to the side of the housing 1 near the discharge port 3 via a rectangular plate.

[0067] Reference Figure 3 and Figure 4 The coating assembly includes a trapezoidal coating plate 6 bolted to the housing 1. The bottom of the trapezoidal coating plate 6 is lower than the top of the first conveying roller 4 and the bottom of the guide roller 5 located below it. Multiple sliding rods 9 slide through the trapezoidal coating plate 6. A fixed plate 10 is bolted to the top of each sliding rod 9. A first spring 11, fixedly connected to the bottom of the fixed plate 10, is sleeved on the outer wall of each sliding rod 9. The bottom end of the first spring 11 is fixedly connected to the top of the trapezoidal coating plate 6. The bottom ends of the multiple sliding rods 9 slide... A collection box 7 is bolted through the trapezoidal coating plate 6. Multiple coating rollers 8 for coating the lower layer of the fabric are rotatably connected inside the collection box 7. A liquid storage tank 12, located above the trapezoidal coating plate 6, is fixedly connected inside the outer shell 1. A connecting pipe 13 is bolted to the bottom of the liquid storage tank 12. An electromagnetic flow valve 14 is fixedly fitted onto the outer wall of the connecting pipe 13. A conduit 15 is bolted to the bottom of the connecting pipe 13. Multiple slurry outlet pipes 16 are bolted to the bottom of the conduit 15, and the slurry outlet pipes 16 are located within the trapezoidal... The coating plate 6 is located near the first conveying roller 4. Under the elastic force of the first spring 11, the coating roller 8 and the trapezoidal coating plate 6 clamp the fabric. During fabric conveying, the fabric drives the coating roller 8 to rotate, while the bottom of the coating roller 8 is immersed in the slurry in the collection box 7. As the coating roller 8 rotates, it can coat the bottom of the fabric, thus coating both sides of the fabric simultaneously. The bottom of the trapezoidal coating plate 6 is lower than the top of the first conveying roller 4. Polyethylene fiber slurry in the storage tank 12 drips onto the fabric, and the slurry on the fabric... The liquid flows towards the trapezoidal coating plate 6. As the first conveying roller 4 and the guide roller 5 convey the fabric, the trapezoidal coating plate 6 comes into contact with the slurry. The trapezoidal coating plate 6 and the slurry work together to coat the upper layer of the fabric. During the coating process, the slurry flows along the two inclined surfaces of the trapezoidal coating plate 6. The slurry drips from the fabric into the collection box 7. The collection box 7 can not only recover the slurry but also coat the lower layer of the fabric through the coating roller 8. Thus, both sides of the fabric can be coated at the same time, and the slurry dripping from the fabric is not wasted.

[0068] Reference Figure 6The scraping assembly includes a fixed plate 17 bolted to the housing 1, a sliding plate 18 slidably connected inside the housing 1, and a bottom of the fixed plate 17 and a top of the sliding plate 18 elastically connected by multiple tension springs 19. An upper scraper 20 and a lower scraper 21 for scraping the surface slurry of the fabric are bolted to the bottom of the fixed plate 17 and the top of the sliding plate 18, respectively. The tension of the tension springs 19 allows the fixed plate 17 and the sliding plate 18 to clamp the fabric, thereby allowing the upper scraper 20 and the lower scraper 21 to scrape the slurry from the upper and lower layers of the fabric. The scraped slurry flows into the storage tank 12 through the second liquid guide trough 40. This not only scrapes both sides of the fabric to ensure its flatness and aesthetics, but also allows for the recycling of the scraped slurry, reducing resource waste.

[0069] Reference Figure 5 The mixing assembly includes a rotating shaft 28 rotatably connected within the outer casing 1, positioned between two guide rollers 5. Multiple rubber wheels 29 are fixedly fitted onto the outer wall of the rotating shaft 28, and the outer walls of the rubber wheels 29 contact the outer walls of the two guide rollers 5. Multiple triangular push blocks 30 are bolted to the outer wall of the rotating shaft 28. A support plate 31 is bolted to the inner casing 1. A trapezoidal rod 32, cooperating with the triangular push blocks 30, slides through the support plate 31. A stop block 34 is fixedly fitted onto the outer wall of the trapezoidal rod 32, and a second spring 35 is fixedly connected to the stop block 34. One end of the rod away from the stop block 34 is fixedly connected to the storage tank 12. The end of the trapezoidal rod 32 away from the rotating shaft 28 extends slidably into the storage tank 12 and is fixedly connected to the push plate 33 by bolts. The push plate 33 is slidably connected to the bottom inner wall of the storage tank 12. The friction between the guide roller 5 and the rubber wheel 29 drives the rotating shaft 28 to rotate counterclockwise. The triangular push block 30 cooperates with the trapezoidal rod 32 and can push the trapezoidal rod 32 and the push plate 33 to the right. As the rotating shaft 28 and the triangular push block 30 rotate, they can drive the push plate 33 to move back and forth in the storage tank 12, stirring the slurry in the storage tank 12 and preventing the slurry from settling.

[0070] Reference Figure 3 A liquid pump 37 is fixedly connected to one side of the outer casing 1 by bolts. The inlet of the liquid pump 37 is fixedly fitted with a first hose 36, and one end of the first hose 36 extends into the collection tank 7. The outlet of the liquid pump 37 is fixedly fitted with a second hose 38, and one end of the second hose 38 extends into the storage tank 12. When the slurry collected in the collection tank 7 is about to overflow, the liquid pump 37 is started. The liquid pump 37 guides the slurry collected in the collection tank 7 into the storage tank 12 through the first hose 36 and the second hose 38 to prevent the slurry in the collection tank 7 from overflowing and causing waste.

[0071] Reference Figure 6 , Figure 7 and Figure 9 The upper scraper 20 has a first liquid guiding groove 39 on one side near the guide roller 5, and the sliding plate 18 has a second liquid guiding groove 40 on both sides. The outer wall of the first conveying roller 4 is fixedly fitted with two threaded protrusions 41, and the two threaded protrusions 41 are in opposite directions. When the upper scraper 20 scrapes the upper layer of the fabric, the scraped slurry flows into the first liquid guiding groove 39, and flows to both sides through the guidance of the first liquid guiding groove 39 and drips onto the sliding plate 18. When the lower scraper 21 scrapes the lower layer of the fabric, the slurry flows to the sliding plate 18. On plate 18, the slurry on sliding plate 18 flows into storage tank 12 through the second liquid guide groove 40. This not only scrapes off both sides of the fabric to ensure its flatness, but also allows the scraped slurry to be recycled, reducing resource waste. When the first conveying roller 4 rotates to convey the fabric, the two oppositely oriented threaded protrusions 41 on the outer wall of the first conveying roller 4 can make the fabric stretch and lay flat, preventing the fabric from piling up or wrinkling during the conveying process.

[0072] Reference Figure 10 The outer casing 1 contains an upper drying chamber 42 and a lower drying chamber 43, which are bolted together and located above and below the fabric, respectively. Multiple resistance wire heating elements 44 are bolted to the inner walls of the upper and lower drying chambers 42 and 43 on opposite sides. A blower 45 is bolted to the top of the upper drying chamber 42, and the air outlet of the upper drying chamber 42 extends into the chamber. An air guide plate 46, located below the fabric, is bolted to the outer casing 1. The side away from the guide roller 5 is fixedly connected to the lower drying box 43 by bolts. The lower drying box 43 is provided with a vent 47 on the side near the air guide plate 46. When the resistance wire heating element 44 and the blower 45 are started, the blower 45 blows the heated air in the upper drying box 42 downward. The hot air can dry the upper layer of the fabric. When the hot air moves downward through the fabric, it is guided by the air guide plate 46 and flows into the lower drying box 43. Then, the hot air in the lower drying box 43 rises to dry the lower layer of the fabric, thus completing the double-sided drying task of the fabric.

[0073] A method of using an ultra-high molecular weight polyethylene fiber coating device includes the following steps:

[0074] S1. The winding roller 22, the first conveying roller 4, and the guiding roller 5 are driven to rotate by motors (the motors are not shown in the diagram). The first conveying roller 4 and the guiding roller 5 convey the fabric, and the winding roller 22 winds up the fabric after coating. The electromagnetic flow valve 14 is activated, and the polyethylene fiber slurry in the storage tank 12 drips onto the fabric through the connecting pipe 13, the conduit 15, and the slurry outlet pipe 16. Since the bottom of the trapezoidal coating plate 6 is lower than the top of the first conveying roller 4, the slurry dripping onto the fabric flows towards the trapezoidal coating plate 6. As the first conveying roller 4 and the guiding roller 5 convey the fabric, the trapezoidal coating plate 6 comes into contact with the slurry. Thus, the trapezoidal coating plate 6 and the slurry work together to coat the upper layer of the fabric. During the coating process, the slurry flows along the two inclined surfaces of the trapezoidal coating plate 6, and then the slurry drips from the fabric into the collection box 7.

[0075] S2. Due to the elastic force of the first spring 11, the first spring 11 pushes the sliding rod 9 and the fixed plate 10 to move upward. The sliding rod 9 drives the collection box 7 to move upward, so that the fabric can be clamped by the coating roller 8 and the trapezoidal coating plate 6. During the fabric conveying process, the fabric drives the coating roller 8 to rotate, and the bottom of the coating roller 8 is immersed in the slurry in the collection box 7. As the coating roller 8 rotates, the coating roller 8 can coat the bottom of the fabric, so that both sides of the fabric can be coated at the same time, and the slurry dripping from the fabric is not wasted.

[0076] S3. After being guided and conveyed by the guide roller 5, the coated fabric passes between the fixed plate 17 and the sliding plate 18. The tension of the tension spring 19 enables the fixed plate 17 and the sliding plate 18 to clamp the fabric, thereby allowing the upper scraper 20 and the lower scraper 21 to scrape off the slurry from the upper and lower layers of the fabric. When the upper scraper 20 scrapes off the upper layer of the fabric, the scraped slurry flows into the upper scraper 20 and flows to both sides and drips onto the sliding plate 18 under the guidance of the upper scraper 20. When the lower scraper 21 scrapes off the lower layer of the fabric, the slurry flows onto the sliding plate 18. The slurry on the sliding plate 18 flows into the storage tank 12 through the second liquid guide groove 40. This not only scrapes off both sides of the fabric to ensure the flatness of the fabric, but also allows the scraped slurry to be recycled, reducing the waste of resources.

[0077] S4. When the two guide rollers 5 rotate clockwise to convey the fabric, the friction between the guide rollers 5 and the rubber wheel 29 drives the rotating shaft 28 and the triangular push block 30 to rotate counterclockwise. The inclined surface of the triangular push block 30 contacts the inclined surface of the trapezoidal rod 32, and the triangular push block 30 can push the trapezoidal rod 32, the stop block 34 and the push plate 33 to the right. The second spring 35 begins to compress. When the triangular push block 30 disengages from the trapezoidal rod 32, the trapezoidal rod 32 and the push plate 33 return to their original positions under the elastic force of the second spring 35. Then, with the rotation of the rotating shaft 28 and the triangular push block 30, the push plate 33 can be driven to move back and forth in the liquid storage tank 12 to stir the slurry in the liquid storage tank 12 and prevent the slurry from settling.

[0078] S5. When the slurry collected in the collection box 7 is about to overflow, start the pump 37. The pump 37 introduces the slurry collected in the collection box 7 into the storage tank 12 through the first hose 36 and the second hose 38 to prevent the slurry in the collection box 7 from overflowing and causing waste. In addition, start the resistance wire heating element 44 and the blower 45. The blower 45 blows the heated air in the upper drying box 42 downward. The hot air can dry the upper layer of the fabric. When the hot air moves downward through the fabric, it is guided by the air guide plate 46 and flows into the lower drying box 43. Then the hot air in the lower drying box 43 rises to dry the lower layer of the fabric, completing the double-sided drying task of the fabric.

[0079] S6. The winding roller 22 rotates to complete the winding of the dried fabric. As the winding roller 22 winds up, the thickness of the fabric on the outer wall of the winding roller 22 gradually increases. Under the torsion of the torsion spring 26, the U-shaped frame 25 tightly makes the guide wheel 27 contact the fabric on the outer wall of the winding roller 22, so that the winding roller 22 can wind up the fabric more smoothly and avoid wrinkles on the winding roller 22.

[0080] However, as is well known to those skilled in the art, the working principles and wiring methods of the electromagnetic flow valve 14, the resistance wire heating element 44, the blower 45 and the liquid pump 37 are commonplace and belong to conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.

10. The method of using the ultra-high molecular weight polyethylene fiber coating device according to claim 9, characterized in that, Includes the following steps: S1. The winding roller (22), the first conveying roller (4), and the guiding roller (5) are driven to rotate by motors respectively. The first conveying roller (4) and the guiding roller (5) convey the fabric. The winding roller (22) winds up the fabric after coating. The electromagnetic flow valve (14) is activated. The polyethylene fiber slurry in the storage tank (12) drips onto the fabric through the connecting pipe (13), the guide pipe (15), and the slurry outlet pipe (16). Due to the bottom of the trapezoidal coating plate (6) The top of the first conveying roller (4) is lower than the top of the first conveying roller (4), and the slurry dripping onto the fabric flows toward the trapezoidal coating plate (6). As the first conveying roller (4) and the guide roller (5) convey the fabric, the trapezoidal coating plate (6) comes into contact with the slurry. The trapezoidal coating plate (6) and the slurry work together to coat the upper layer of the fabric. During the coating process, the slurry flows along the two inclined surfaces of the trapezoidal coating plate (6), and the slurry drips from the fabric into the collection box (7). S2. Due to the elastic force of the first spring (11), the first spring (11) pushes the sliding rod (9) and the fixed plate (10) to move upward. The sliding rod (9) drives the collection box (7) to move upward, so that the fabric can be clamped by the coating roller (8) and the trapezoidal coating plate (6). During the fabric conveying process, the fabric drives the coating roller (8) to rotate, and the bottom of the coating roller (8) is immersed in the slurry in the collection box (7). As the coating roller (8) rotates, the coating roller (8) can coat the bottom of the fabric, so that both sides of the fabric can be coated at the same time, and the slurry dripping from the fabric is not wasted. S3. After being guided and conveyed by the guide roller (5), the coated fabric passes between the fixed plate (17) and the sliding plate (18). The tension of the tension spring (19) enables the fixed plate (17) and the sliding plate (18) to clamp the fabric, thereby allowing the upper scraper (20) and the lower scraper (21) to scrape off the slurry on the upper and lower layers of the fabric. When the upper scraper (20) scrapes off the upper layer of the fabric, the scraped slurry flows into the upper scraper (20), and flows to both sides and drips onto the sliding plate (18) through the guidance of the upper scraper (20). When the lower scraper (21) scrapes off the lower layer of the fabric, the slurry flows onto the sliding plate (18), and the slurry on the sliding plate (18) flows into the storage tank (12) through the guidance of the second liquid guide groove (40). This not only scrapes off both sides of the fabric to ensure the flatness of the fabric, but also allows the scraped slurry to be recycled, reducing the waste of resources. S4. When the two guide rollers (5) rotate clockwise to convey the fabric, the friction between the guide rollers (5) and the rubber wheel (29) drives the rotating shaft (28) and the triangular push block (30) to rotate counterclockwise. The inclined surface of the triangular push block (30) touches the inclined surface of the trapezoidal rod (32), and the triangular push block (30) can push the trapezoidal rod (32), the stop block (34) and the push plate (33) to move to the right. The second spring (35) begins to compress. When the triangular push block (30) and the trapezoidal rod (32) disengage, the trapezoidal rod (32) and the push plate (33) reset under the elastic force of the second spring (35). Then, with the rotation of the rotating shaft (28) and the triangular push block (30), the push plate (33) can move back and forth in the storage tank (12) to stir the slurry in the storage tank (12) and prevent the slurry from settling. S5. When the slurry collected in the collection box (7) is about to overflow, start the pump (37). The pump (37) introduces the slurry collected in the collection box (7) into the storage tank (12) through the first hose (36) and the second hose (38) to prevent the slurry in the collection box (7) from overflowing and causing waste. In addition, start the resistance wire heating plate (44) and the blower (45). The blower (45) blows the heated air in the upper drying box (42) downward. The hot air can dry the upper layer of the fabric. When the hot air moves downward through the fabric, it is guided by the air guide plate (46) and flows into the lower drying box (43). Then the hot air in the lower drying box (43) rises to dry the lower layer of the fabric, completing the double-sided drying task of the fabric. S6. The winding roller (22) rotates to complete the winding of the dried fabric. As the winding roller (22) winds up, the thickness of the fabric on the outer wall of the winding roller (22) gradually increases. Under the torsion of the torsion spring (26), the U-shaped frame (25) tightly makes the guide wheel (27) contact the fabric on the outer wall of the winding roller (22), so that the winding roller (22) can wind up the fabric more smoothly and avoid wrinkles on the winding roller (22).
