Abstract
Description
Technical Field
[0001] This invention relates to the field of sizing, and in particular to a sizing process for high-concentration, low-viscosity sizing agents and sizing equipment thereof. Background Technology
[0002] Sizing is a crucial pretreatment process before textile weaving. Its core principle is to ensure thorough contact between the warp yarn and the sizing agent. Through steps such as soaking, pressing, and drying, the sizing agent evenly coats the yarn surface and penetrates its interior, thereby enhancing warp strength, improving abrasion resistance, reducing fuzz, and improving the yarn's resistance to breakage and friction. This provides protection against repeated friction and stretching from heddles and reeds during subsequent weaving, preventing yarn fuzzing and breakage, and ensuring weaving continuity and fabric quality. The supporting sizing equipment, centered around a sizing machine, integrates key components such as a warp frame, sizing tank, drying device, yarn separating device, and winding device. It enables integrated operations of warp unwinding, uniform sizing, efficient drying, precise yarn separating, and neat winding. Its operational stability and ability to control sizing uniformity directly affect sizing agent utilization, sizing film quality, and subsequent weaving efficiency. However, compared with traditional sizing equipment, when yarn enters the sizing tank for sizing, multiple strands of yarn are prone to squeezing, overlapping, or even tangling. This causes some yarns to be blocked during sizing, resulting in leakage or over-sizing. Furthermore, tangled yarns are prone to breakage during traction, requiring frequent machine stops for cleaning and significantly reducing production efficiency. Unevenly sized yarns entering the weaving stage are prone to problems such as yarn breakage, skipped yarns, and defects, resulting in a lower finished product qualification rate.

[0017] In a preferred embodiment, a support base is fixedly connected to the bottom of the slurry tank, the inner wall of the support base is rotatably connected to the output rod, and a drive bevel gear is fixedly connected to the end of the output rod.

[0020] The technical effect of adopting the above-mentioned further solution is that by setting the forward-rotating agitator and the reverse-rotating agitator to rotate synchronously in opposite directions, the slurry is efficiently and evenly dispersed to form a high-concentration, low-viscosity slurry, thereby improving the sizing speed and sizing effect of the yarn.
[0021] A sizing process for high-concentration, low-viscosity sizing agents in a sizing equipment includes the following steps: S1. Achieve independent positioning of single yarns and avoid mutual interference: When the yarn is introduced into the sizing tank through the guide roller, the positioning grooves on the surfaces of the first pressure roller, the second pressure roller and the third pressure roller correspond one by one, and the guide arc edge of the positioning groove can quickly guide the yarn into the groove, so that each yarn is in the exclusive channel of the positioning groove for independent sizing, effectively avoiding the squeezing, overlapping and tangling between multiple yarns, thereby preventing uneven sizing and traction breakage, and improving the sizing qualification rate and quality; S2. Synchronous rotation of pressure rollers reduces yarn friction damage: After the motor is started, the output rod drives the first driving pulley to rotate, which in turn drives the first driven pulley via the first belt, causing the first pressure roller to rotate. Simultaneously, the first pressure roller rotates synchronously via the second driving pulley and the second belt, driving the second driven pulley. It also rotates synchronously via the third driving pulley and the third belt, driving the third driven pulley. This multi-pressure roller synchronous rotation design, combined with the increased contact area from the limiting groove, reduces friction between the yarn and the pressure rollers, preventing surface damage during yarn sizing. S3. Two-way stirring to prevent slurry sedimentation: When the motor drives the output rod to rotate, the active bevel gear at the end of the output rod rotates synchronously, meshing with the first driven bevel gear and the second driven bevel gear respectively. This causes the outer sleeve and the inner shaft to rotate in opposite directions, thereby driving the forward-rotating and reverse-rotating stirring paddles to rotate synchronously in opposite directions within the sizing tank. This process can efficiently and evenly disperse the slurry, preventing the components from settling after the slurry has been left to stand, avoiding a situation where the slurry at the bottom of the tank is viscous and the upper layer is thin, resulting in large fluctuations in sizing quality. This creates a high-concentration, low-viscosity slurry, thereby improving the speed and effect of yarn sizing. S4. Adjustable tension and improved sizing quality: During the sizing process, by activating the electric push rod, its output end pushes the slide table to slide along the guide rod. The slide table slides and engages with the slide roller on the side of the third pressure roller through the slide groove, causing the third pressure roller to rotate around the rotating seat, thereby changing the distance between the third pressure roller and the second pressure roller, realizing flexible adjustment of the sizing tension of the yarn, and further improving the sizing quality. S5. Sizing liquid recycling, material saving and ensuring uniform sizing film: When the sized yarn passes through the two squeezing rollers in the drain tank, the squeezing rollers squeeze and remove excess sizing liquid from the yarn surface. The excess sizing liquid flows back into the sizing tank from the arc-shaped bottom of the drain tank for recycling, which saves sizing liquid and ensures that the sizing film on the yarn surface is uniformly covered.
[0022] This invention provides a sizing process for high-concentration, low-viscosity sizing agents and its sizing equipment. It offers the following advantages: By using three pressure rollers, each yarn is individually sized in its own dedicated channel within the limiting groove, effectively avoiding squeezing, overlapping, and tangling between multiple yarns, thereby preventing uneven sizing and traction breakage, and improving the sizing pass rate and quality.
[0023] By pushing the slide table along the guide rod, the slide table uses the sliding groove to slide and engage with the sliding roller at the side of the third pressure roller, causing the third pressure roller to rotate around the rotating base, thereby changing the distance between the third pressure roller and the second pressure roller, realizing flexible adjustment of the sizing tension of the yarn, and further improving the sizing quality.
[0024] The stirring paddles rotate synchronously in opposite directions within the sizing tank. This process efficiently and evenly disperses the sizing liquid, preventing sedimentation after settling, avoiding a viscous sizing liquid at the bottom and a thin sizing liquid at the top, which would result in large fluctuations in sizing quality. This process creates a high-concentration, low-viscosity sizing liquid, thereby improving the speed and effectiveness of yarn sizing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this invention provides a sizing and yarn-sizing device for high-concentration, low-viscosity sizing agents, including a sizing tank 1. A support leg 2 is fixedly connected to the lower end of the sizing tank 1. A guide roller 3 is provided at the upper end of the sizing tank 1, through which yarn is introduced into and drawn out of the sizing tank 1. A first pressure roller 4 is rotatably connected inside the sizing tank 1, with the inner circumference of the sizing tank 1 equal to the outer circumference of the first pressure roller 4. A second pressure roller 5 is rotatably connected inside the sizing tank 1, with the inner circumference of the sizing tank 1 equal to the outer circumference of the second pressure roller 5. The surface of the sizing tank 1 is fixed... A rotating base 6 is connected, and a rotating plate 7 is rotatably connected to the inner side of the rotating base 6. The outer circumference of the rotating base 6 is equal to the inner circumference of the rotating plate 7. A third pressure roller 8 is rotatably connected to the surface of the rotating plate 7. Several limiting grooves 9 are respectively opened on the surfaces of the first pressure roller 4, the second pressure roller 5 and the third pressure roller 8. A guide arc edge 10 is provided at the edge of the limiting groove 9. The yarn can be quickly guided into the limiting groove 9 for limiting through the guide arc edge 10. The limiting grooves 9 on the surfaces of the first pressure roller 4, the second pressure roller 5 and the third pressure roller 8 correspond one-to-one. The first pressure roller 4, the second pressure roller 5, and the third pressure roller 8 provide tension and guidance for the sized yarn; The guide arc edge 10 is used to guide the yarn into the limiting groove 9 for limiting and isolation. By opening the limiting groove 9 on the surface of the pressure roller, the single yarn is independently limited and sized within the limiting groove 9. Each yarn has its own dedicated channel and does not interfere with each other, thereby avoiding the situation of squeezing, overlapping or even tangling between multiple yarns, which would cause uneven sizing and traction breakage, thus improving the qualified rate and quality of yarn sizing.
[0029] like Figures 1-2As shown: A motor 11 is installed on the side of the sizing tank 1. An output rod 12 is fixedly connected to the output end of the motor 11. The output rod 12 is rotated by the motor 11. A first driving pulley 13 is fixedly connected to the surface of the output rod 12. A first driven pulley 14 is fixedly connected to the side of the first pressure roller 4. A first belt 15 is installed on the surface of the first driving pulley 13. The surface of the first driving pulley 13 is connected to the first driven pulley 14 through the first belt 15. When the motor 11 is started, the output rod 12 is rotated by the motor 11. The rotation of the output rod 12 causes the first driving pulley 13 to rotate accordingly. The first driving pulley 13 drives the first driven pulley 14 to rotate through the first belt 15, so that the first pressure roller 4 rotates in the sizing tank 1.
[0030] like Figures 1-4 As shown: A second driving pulley 16 is fixedly connected to the surface of the first pressure roller 4, and a second driven pulley 17 is fixedly connected to the side end of the second pressure roller 5. A second belt 18 is provided on the surface of the second driving pulley 16. The surface of the second driving pulley 16 is connected to the second driven pulley 17 through the second belt 18. When the first pressure roller 4 rotates, it drives the second driving pulley 16 to rotate as well. The second driving pulley 16 drives the second driven pulley 17 to rotate through the second belt 18, so that when the first pressure roller 4 rotates, the second pressure roller 5 rotates synchronously.
[0031] like Figures 2-4 As shown: A third driving pulley 19 is fixedly connected to the surface of the first pressure roller 4, and a third driven pulley 20 is fixedly connected to the side end of the third pressure roller 8. A third belt 21 is provided on the surface of the third driving pulley 19. The surface of the third driving pulley 19 is connected to the third driven pulley 20 through the third belt 21. When the first pressure roller 4 rotates, it drives the third driving pulley 19 to rotate as well. The third driving pulley 19 drives the third driven pulley 20 to rotate through the third belt 21. This allows the first pressure roller 4 to rotate while the third pressure roller 8 rotates synchronously. As the yarn passes through, the contact area is increased by opening the limiting groove 9. The first pressure roller 4, the second pressure roller 5, and the third pressure roller 8 rotate synchronously, reducing friction and preventing surface damage during yarn sizing.
[0032] like Figure 2 As shown: A guide seat 22 is fixedly connected to the side end of the slurry tank 1. A guide rod 23 is fixedly connected to the surface of the guide seat 22. A slide table 24 is slidably connected to the surface of the guide rod 23. The outer circumference of the guide rod 23 is equal to the inner circumference of the slide table 24. The slide table 24 can slide along the surface of the guide rod 23 and the side end of the slurry tank 1.
[0033] like Figures 2-4As shown: The side end of the third pressure roller 8 is rotatably connected to a sliding roller 25. The surface of the slide table 24 is provided with a sliding groove 26. The slide table 24 is slidably connected to the sliding roller 25 through the sliding groove 26. The side end of the sizing tank 1 is fixedly connected to an electric push rod 27. The output end of the electric push rod 27 is fixedly connected to the slide table 24, so that the third pressure roller 8 can rotate at the side end of the sizing tank 1 under the push of the electric push rod 27, thereby changing the distance between the third pressure roller 8 and the second pressure roller 5, thereby adjusting the tension of the yarn during sizing and improving the sizing quality.
[0034] like Figure 1 As shown: A drain tank 28 is fixedly connected to the side end of the sizing tank 1. A squeezing roller 29 is rotatably connected to the inner wall of the drain tank 28. There are two squeezing rollers 29. The drain tank 28 is adapted to the squeezing roller 29. The bottom of the drain tank 28 is an arc surface. After sizing, the yarn passes between the two squeezing rollers 29. The excess sizing liquid is removed by the squeezing of the squeezing rollers 29. The excess sizing liquid flows back into the sizing tank 1 from the arc bottom of the drain tank 28 for recycling, thereby ensuring uniform coverage of the sizing film.
[0035] like Figures 6-7 As shown: A support base 30 is fixedly connected to the bottom of the slurry tank 1. The inner wall of the support base 30 is rotatably connected to the output rod 12. The inner circumference of the support base 30 is equal to the outer circumference of the output rod 12. An active bevel gear 31 is fixedly connected to the end of the output rod 12. When the motor 11 starts, it drives the output rod 12 to rotate, so that the output rod 12 at the bottom of the slurry tank 1 drives the active bevel gear 31 to rotate synchronously.
[0036] like Figures 6-7As shown: An outer sleeve 32 is rotatably connected to the bottom of the sizing tank 1. The inner circumference of the sizing tank 1 is equal to the outer circumference of the outer sleeve 32. A first driven bevel gear 33 is fixedly connected to the bottom of the outer sleeve 32. The surface of the first driven bevel gear 33 meshes with the driving bevel gear 31. The first driven bevel gear 33 and the driving bevel gear 31 are adapted to each other. An inner rotating shaft 34 is rotatably connected to the inner wall of the outer sleeve 32. The inner circumference of the outer sleeve 32 is equal to the outer circumference of the inner rotating shaft 34. A second driven bevel gear 35 is fixedly connected to the bottom end of the inner rotating shaft 34. The surface of the second driven bevel gear 35 meshes with the driving bevel gear 31. The second driven bevel gear 35 and the driving bevel gear 31 are adapted to each other. The upper end of the outer sleeve 32 is fixedly connected to the inner wall of the outer sleeve 32. A forward-rotating agitator 36 is fixedly connected to the inner rotating shaft 34, and a reverse-rotating agitator 37 is fixedly connected to the upper end of the inner rotating shaft 34. When the motor 11 starts, it drives the active bevel gear 31 to rotate, which in turn drives the first driven bevel gear 33 and the second driven bevel gear 35 to rotate synchronously in opposite directions. This, in turn, drives the outer sleeve 32 and the inner rotating shaft 34, which are fixedly connected to them, to rotate. This causes the forward-rotating agitator 36 and the reverse-rotating agitator 37 to rotate synchronously in opposite directions with the sizing tank 1, which efficiently and evenly disperses the sizing liquid. This prevents the components from settling after the sizing liquid has been left to stand, avoiding the sizing liquid at the bottom of the tank from being viscous and the upper layer from being thin, resulting in large fluctuations in sizing quality. This forms a high-concentration, low-viscosity sizing material, thereby improving the sizing speed and sizing effect of the yarn.
[0037] A sizing process for high-concentration, low-viscosity sizing agents in a sizing equipment includes the following steps: S1. Achieving independent positioning of single yarns and avoiding mutual interference: When the yarn is introduced into the sizing tank 1 through the guide roller 3, the limiting grooves 9 on the surfaces of the first pressure roller 4, the second pressure roller 5 and the third pressure roller 8 correspond one-to-one, and the guiding arc edge 10 on the edge of the limiting groove 9 can quickly guide the yarn into the groove, so that each yarn is independently sized in the exclusive channel of the limiting groove 9, effectively avoiding the squeezing, overlapping and tangling between multiple yarns, thereby preventing uneven sizing and traction breakage, and improving the sizing qualification rate and quality.
[0038] S2. Synchronous rotation of pressure rollers reduces yarn friction damage: After starting the motor 11, the output rod 12 drives the first driving pulley 13 to rotate, which in turn drives the first driven pulley 14 via the first belt 15, causing the first pressure roller 4 to rotate. Simultaneously, the first pressure roller 4 drives the second driven pulley 17 via the second driving pulley 16 and the second belt 18, causing the second pressure roller 5 to rotate synchronously. It also drives the third driven pulley 20 via the third driving pulley 19 and the third belt 21, causing the third pressure roller 8 to rotate synchronously. This multi-pressure roller synchronous rotation design, combined with the increased contact area of the limiting groove 9, reduces friction between the yarn and the pressure rollers through synchronous rotation of the pressure rollers, preventing surface damage during yarn sizing.
[0039] S3. Two-way stirring to prevent slurry sedimentation: When the motor 11 drives the output rod 12 to rotate, the driving bevel gear 31 at the end of the output rod 12 rotates synchronously, meshing with the first driven bevel gear 33 and the second driven bevel gear 35 respectively. This causes the outer sleeve 32 and the inner rotating shaft 34 to rotate in opposite directions, thereby driving the forward-rotating stirring paddle 36 and the reverse-rotating stirring paddle 37 to rotate synchronously in opposite directions within the sizing tank 1. This process can efficiently and evenly disperse the slurry, preventing the components from settling after the slurry has been left to stand. It also prevents the slurry at the bottom of the tank from becoming viscous and the upper layer from becoming thin, resulting in large fluctuations in sizing quality. This creates a high-concentration, low-viscosity slurry, thereby improving the sizing speed and effect on the yarn.
[0040] S4. Adjustable tension and improved sizing quality: During the sizing process, by activating the electric push rod 27, its output end pushes the slide table 24 to slide along the guide rod 23. The slide table 24 slides and engages with the slide roller 25 on the side of the third pressure roller 8 through the slide groove 26, causing the third pressure roller 8 to rotate around the rotating seat 6, thereby changing the distance between the third pressure roller 8 and the second pressure roller 5, realizing flexible adjustment of the sizing tension on the yarn, and further improving the sizing quality.
[0041] S5. Sizing liquid recycling, material saving and ensuring uniform sizing film: When the sized yarn passes through the two squeezing rollers 29 in the drain tank 28, the squeezing rollers 29 squeeze and remove excess sizing liquid from the surface of the yarn. The excess sizing liquid flows back to the sizing tank 1 from the arc-shaped bottom of the drain tank 28 for recycling, which saves sizing liquid and ensures that the sizing film on the surface of the yarn is uniformly covered.
[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.

10. A high-concentration, low-viscosity sizing process for a sizing equipment, based on the high-concentration, low-viscosity sizing equipment according to any one of claims 1-9, characterized in that: Includes the following steps: S1. Achieve independent positioning of single yarn and avoid mutual interference: When the yarn is introduced into the sizing tank (1) through the guide roller (3), the limiting grooves (9) on the surface of the first pressure roller (4), the second pressure roller (5) and the third pressure roller (8) correspond one by one, and the guiding arc edge (10) of the limiting groove (9) can quickly guide the yarn into the groove, so that each yarn is independently sized in the exclusive channel of the limiting groove (9), effectively avoiding the squeezing, overlapping and tangling between multiple yarns, thereby preventing uneven sizing and traction breakage, and improving the sizing qualification rate and quality; S2. Synchronous rotation of pressure rollers reduces yarn friction damage: After starting the motor (11), the output rod (12) drives the first driving pulley (13) to rotate, which in turn drives the first driven pulley (14) through the first belt (15), causing the first pressure roller (4) to rotate. At the same time, the first pressure roller (4) drives the second driven pulley (17) through the second driving pulley (16) and the second belt (18), causing the second pressure roller (5) to rotate synchronously. It also drives the third driven pulley (20) through the third driving pulley (19) and the third belt (21), causing the third pressure roller (8) to rotate synchronously. This multi-pressure roller synchronous rotation design, combined with the increased contact area of the limiting groove (9), can reduce the friction between the yarn and the pressure roller through synchronous rotation of the pressure rollers, avoiding surface damage when sizing the yarn. S3. Two-way stirring to prevent slurry sedimentation: When the motor (11) drives the output rod (12) to rotate, the active bevel gear (31) at the end of the output rod (12) rotates synchronously, and it meshes with the first driven bevel gear (33) and the second driven bevel gear (35) respectively, causing the outer sleeve (32) and the inner rotating shaft (34) to rotate in opposite directions, thereby driving the forward-rotating stirring paddle (36) and the reverse-rotating stirring paddle (37) to rotate synchronously in opposite directions in the sizing tank (1). This process can efficiently and evenly disperse the slurry, avoid the sedimentation of components after the slurry has been left to stand, and prevent the slurry at the bottom of the tank from becoming viscous and the upper layer from becoming thin, resulting in large fluctuations in sizing quality, thus forming a high-concentration, low-viscosity slurry, thereby improving the sizing speed and effect on the yarn; S4. Adjustable tension and improved sizing quality: During the sizing process, by starting the electric push rod (27), its output end pushes the slide table (24) to slide along the guide rod (23). The slide table (24) slides and engages with the slide roller (25) on the side of the third pressure roller (8) through the slide groove (26), so that the third pressure roller (8) rotates around the turntable (6), thereby changing the distance between the third pressure roller (8) and the second pressure roller (5), realizing flexible adjustment of the sizing tension of the yarn, and further improving the sizing quality; S5. Sizing liquid recycling, material saving and ensuring uniform sizing film: When the sized yarn passes through the two squeezing rollers (29) in the drain pool (28), the squeezing rollers (29) squeeze and remove excess sizing liquid from the surface of the yarn. The excess sizing liquid flows back to the sizing pool (1) from the arc-shaped bottom of the drain pool (28) for recycling, which saves sizing liquid and ensures that the sizing film on the surface of the yarn is uniformly covered.
