Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber processing technology, and specifically relates to a winding structure for polyester master yarn. Background Technology

[0002] Polyester filament is the commercial name for polyester fiber in China. Its characteristics include resistance to chemicals and frequent washing, reducing fading and discoloration in clothing. Therefore, it is used in hotel uniforms, stonewashed denim, sportswear, and children's clothing. Relatively speaking, polyester filament is more durable than rayon. When embroidering, even with high-speed machine operation, the high-tenacity polyester thread can withstand significant tensile force. Furthermore, it has extremely high fire resistance; even when clothing is near a flame, it is not easily ignited. Polyester masterfilament, similar to conventional yarn, has a multifilament structure. Multifilament is a thread composed of multiple monofilaments arranged in parallel. Polyester masterfilament is one such combination. Through a specific separation process, polyester masterfilament can be broken down into several independent monofilaments. The winding structure of polyester masterfilament is a structure used to wind up the polyester masterfilament during processing for easy storage.

[0003] However, the traditional polyester filament winding structure relies on bolts to fix the winding roller, and special tools are required for loading and unloading, which increases the time spent on production line changeover. At the same time, it is easy to cause local over-tension damage during winding, and loose or tight edges are prone to occur when the winding speed fluctuates, which directly affects the processing stability of subsequent textile processes.

[0004] To address the problems mentioned in the background above, a winding structure for polyester master yarn is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a winding structure for polyester master yarn, which has the advantages of easy disassembly and cushioning protection.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a winding structure for polyester master yarn, including a base, brackets are bolted to both sides of the top rear end of the base, a rotating rod is provided on the opposite side of the bracket, and the left side of the left rotating rod is rotatably connected to the right side of the left bracket, a motor is embedded in the left side of the right bracket, and the left side of the motor is fixedly sleeved to the right side of the right rotating rod, a spring is bolted to the inner end of the two rotating rods, a locking rod is bolted to the end of the spring away from the rotating rod, and the surface of the locking rod is slidably sleeved with the inner wall of the rotating rod, a locking groove is engaged at the end of the locking rod away from the spring, a winding roller is provided on the outer surface of the locking groove, and an adjustment mechanism is provided on the top of the base.

[0007] The above technical solution is as follows: When installing the take-up roller, press the locking lever. After being subjected to external force, the locking lever slides axially along the inner wall of the rotating rod, while simultaneously compressing the first spring inside the rotating rod until the locking lever is fully retracted into the rotating rod. Place the take-up roller between the two rotating rods. After releasing the take-up roller, the first spring releases its elastic potential energy, pushing the locking lever to slide outward along the inner wall of the rotating rod and engage in the slots at both ends of the take-up roller, completing the installation. Start the motor, and the motor output shaft drives the right rotating rod to rotate. The right rotating rod drives the take-up roller to rotate through the locking lever, while the left rotating rod rotates synchronously with the take-up roller, allowing the polyester filament to be wound up. After winding is complete, press the locking lever. The locking lever slides inward along the inner wall of the rotating rod and compresses the first spring, disengaging from the slot constraint, allowing the take-up roller to be removed from between the rotating rods. The installation and disassembly of the take-up roller can be completed quickly without the aid of tools, significantly shortening the process changeover time and significantly improving work efficiency. The purely mechanical structure is simple and reliable, reducing the impact of downtime maintenance, and ensuring high stability during long-term use, thus ensuring dynamic balance during winding.

[0008] The present invention is further configured such that the adjusting mechanism includes a slide groove, the slide groove is opened on both sides of the top front end of the base, a slider is slidably connected in the middle of the inner wall of the slide groove, a bracket two is bolted to the top of the slider, a spring two is bolted to the front and back of the slider, and the end of the spring two away from the slider is bolted to the front and rear ends inside the slide groove, and a guide roller is rotatably connected to the opposite side of the two brackets two.

[0009] The above technical solution employs an adjustment mechanism. Under normal conditions, the slider is positioned in the middle of the chute under the balancing force of spring two, and the guide roller maintains a stable height and angle. The filament passes under the guide roller, forming a stable conveying path. When the tension of the filament increases, the pressure of the filament on the guide roller increases, pushing the support two and the slider to slide along the chute in the direction of tension. At this time, the slider compresses spring two on the corresponding side, and the elastic reaction force of spring two offsets part of the tension, preventing the filament from breaking due to excessive tightness. When the tension of the filament decreases, spring two releases potential energy to push the slider back to its original position, and the guide roller tightens the filament, preventing the filament from loosening and causing tangling. The sliding cooperation between the slider and the chute ensures that the guide roller moves only in the front-to-back direction, avoiding lateral deviation that affects the direction of the filament. The dynamic adaptive adjustment elastic compensation mechanism absorbs fiber tension fluctuations in real time, ensuring that the filament bundle maintains a relatively constant contact pressure during winding. The adaptive guiding mechanism can correct fiber trajectory deviations, effectively reducing the overlapping and loose edge phenomena common in traditional structures, reducing frictional damage between the filament and the roller surface, and further ensuring winding quality. This dynamic balance characteristic significantly improves the quality of package forming and production continuity.

[0010] The present invention is further configured such that the top and bottom of the rotating rod surface near the bracket end are provided with slots, and the top and bottom of the clamping rod are bolted with pull rods.

[0011] The above technical solution is adopted: by setting a slot and a pull rod, the pull rod can be easily pressed to lock the lever, and the slot can limit the movement of the lever.

[0012] The present invention is further configured such that a damper is sleeved inside the spring.

[0013] The above technical solution involves setting a damper to limit the movement of spring 1 and prevent spring 1 from rebounding.

[0014] The present invention is further configured such that the lever and the slot are square.

[0015] The above technical solution allows the take-up roller to rotate via a clamping rod and slot, preventing it from spinning idly.

[0016] The present invention is further configured such that a sleeve is fitted onto the surface of the take-up roller.

[0017] The above technical solution involves using a sleeve to wind the polyester filament into the sleeve, which can be removed after winding for easy storage.

[0018] The present invention is further configured such that a baffle is fixedly sleeved at the end of the rotating rod surface away from the support.

[0019] The above technical solution, by setting up baffles, can prevent the polyester master yarn from deviating during the winding process.

[0020] The present invention is further configured such that the height of the guide roller is set to be slightly lower than the horizontal height of the take-up roller.

[0021] The above technical solution is adopted: by setting the height slightly lower than that of the take-up roller, this height difference can make the filament form an inclined wrap angle between the tension roller and the take-up roller. When the tension roller moves back and forth due to tension fluctuations, the tension feedback sensitivity can be enhanced by the slight change in the wrap angle. If the two are horizontal, the contact angle between the filament and the roller surface is close to zero degrees, and slippage is likely to occur during tension adjustment.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model allows for quick installation and disassembly of the take-up roller without the need for tools, significantly shortening process changeover time and greatly improving work efficiency. The purely mechanical structure is simple and reliable, reducing the impact of downtime maintenance. It also ensures high stability during long-term use and guarantees dynamic balance during winding.

[0024] 2. This utility model absorbs fiber tension fluctuations in real time through a dynamic adaptive adjustment elastic compensation mechanism, ensuring that the filament bundle maintains a relatively constant contact pressure during the winding process. The adaptive guiding mechanism can correct the deviation of the fiber travel trajectory, effectively reducing the overlapping and loose edge phenomena common in traditional structures, reducing frictional damage between the mother filament and the roller surface, and further ensuring the winding quality. This dynamic balance characteristic significantly improves the quality of package forming and production continuity. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A winding structure for polyester master yarn includes a base 1. Supports 2 are bolted to both sides of the top rear end of the base 1. A rotating rod 4 is provided on the opposite side of each support 2. The left side of the left rotating rod 4 is rotatably connected to the right side of the left support 2. A motor 5 is embedded in the left side of the right support 2, and the left side of the motor 5 is fixedly sleeved to the right side of the right rotating rod 4. The motor 5 has a power of 0.5-2.2kW, a speed of 50-300r / min, a winding speed of 5-30m / min, and an output torque of 10-50N・m. Springs 6 are bolted to the inner ends of the two rotating rods 4, with an elastic coefficient of 10-20N / mm and a free length of 50-80mm. These springs ensure that the clamping force of the clamping rod 8 on the clamping groove 9 is 80-150N, preventing slippage during winding. A clamping rod 8 is bolted to the end of the spring 6 away from the rotating rod 4, and the surface of the clamping rod 8 is slidably sleeved with the inner wall of the rotating rod 4. One end of spring 6 is engaged with a slot 9, and a take-up roller 10 is provided on the outer surface of the slot 9. An adjustment mechanism is provided on the top of the base 1. When installing the take-up roller 10, press the locking rod 8. After the locking rod 8 is subjected to external force, it slides axially along the inner wall of the rotating rod 4, while compressing the spring 6 inside the rotating rod 4, until the locking rod 8 is fully retracted into the rotating rod 4. Place the take-up roller 10 between the two rotating rods 4. After releasing the take-up roller 10, the spring 6 releases its elastic potential energy, pushing the locking rod 8 along the inner wall of the rotating rod 4. Slide it outwards and insert it into the slots 9 at both ends of the take-up roller 10 to complete the installation. Start the motor 5. The output shaft of the motor 5 drives the right rotating rod 4 to rotate. The right rotating rod 4 drives the take-up roller 10 to rotate through the locking rod 8. At the same time, the left rotating rod 4 rotates synchronously with the take-up roller 10, which can wind up the polyester filament. After winding, press the locking rod 8. The locking rod 8 slides inward along the inner wall of the rotating rod 4 and compresses the spring 6. After it is freed from the constraint of the slot 9, the take-up roller 10 can be taken out from between the rotating rods 4.

[0033] refer to Figure 1 , Figure 2 , Figure 3 The top and bottom of the rotating rod 4 near the bracket 2 are provided with slots 14. The top and bottom of the locking rod 8 are bolted with pull rods 15. By setting the slots 14 and pull rods 15, the pull rods 15 can easily press the locking rod 8, and the slots 14 can limit the movement of the locking rod 8. The slot length is 20-30mm.

[0034] refer to Figure 2 , Figure 3 The spring 6 has a damper 16 inside. By setting the damper 16, the spring 6 can be limited and prevented from rebounding. The damping coefficient is 5-10 N·s / m.

[0035] refer to Figure 2 , Figure 3 , Figure 4The locking rod 8 and the locking slot 9 are set to square. By setting them to square, the locking rod 8 and the locking slot 9 can drive the take-up roller 10 to rotate without idling. The square cross-section size is 8×8mm-15×15mm, which is adapted to the diameter of the take-up roller 10, which is 50-200mm in diameter. The gap between the locking rod 8 and the locking slot 9 is 0.05-0.1mm.

[0036] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The surface of the take-up roller 10 is fitted with a sleeve 17. By setting the sleeve 17, the polyester filament is wound on the sleeve 17 and can be taken out after winding, which is convenient for storage. It is made of polyethylene material with a thickness of 2-5mm and a surface roughness Ra0.8-1.6μm to avoid scratching the filament.

[0037] refer to Figure 1 , Figure 2 , Figure 3 A baffle 18 is fixedly sleeved on the end of the rotating rod 4 away from the bracket 2. By setting the baffle 18, the polyester filament can be prevented from deviating during the winding process. The diameter is 20-50mm larger than the winding roller 10, and the thickness is 3-5mm.

[0038] Example 2:

[0039] refer to Figure 1A winding structure for polyester master yarn includes an adjusting mechanism comprising a chute 13. The chute 13 is located on both sides of the top front end of the base 1, and is 100-200mm in diameter. It meets the movement requirements of the slider 12 during tension fluctuations, with a movement range of ±50mm. The slider 12 is slidably connected to the middle of the inner wall of the chute 13. A bracket 2 3 is bolted to the top of the slider 12. Spring 2 7 is bolted to the front and back of the slider 12, and the end of the spring 2 7 away from the slider 12 is bolted to the front and rear ends inside the chute 13. The spring 2 7 has an elastic coefficient of 5-15N / mm, a free length of 80-120mm, a maximum compression of 30-50mm, and is suitable for polyester master yarn tension ranges of 50-300N. Guide rollers 11 are rotatably connected to the opposite sides of the two brackets 2 3. Under the balancing force of spring 7, slider 12 is positioned in the middle of groove 13. Guide roller 11 maintains a stable height and angle. The filament passes under guide roller 11, forming a stable conveying path. When the tension of the filament increases, the pressure of the filament on guide roller 11 increases, pushing bracket 3 and slider 12 to slide along groove 13 in the tension direction. At this time, slider 12 compresses spring 7 on the corresponding side. The elastic reaction force of spring 7 offsets part of the tension, preventing the filament from breaking due to excessive tightness. When the tension of the filament decreases, spring 7 releases potential energy to push slider 12 to reset. Guide roller 11 tightens the filament to prevent it from loosening and causing tangling. The sliding cooperation between slider 12 and groove 13 ensures that guide roller 11 moves only in the front-back direction, avoiding lateral displacement that affects the direction of the filament.

[0040] refer to Figure 1 The height of the guide roller 11 is set slightly lower than the horizontal height of the take-up roller 10. By setting it slightly lower than the horizontal height of the take-up roller 10, this height difference allows the filament to form an inclined wrap angle between the tension roller and the take-up roller 10. When the tension roller moves back and forth due to tension fluctuations, the tension feedback sensitivity can be enhanced by the slight change in the wrap angle. If the two are horizontal, the contact angle between the filament and the roller surface is close to zero degrees, and slippage is likely to occur during tension adjustment. The height difference is 5-15mm.

[0041] Brief description of the usage process: When installing the take-up roller 10, press the locking lever 8. After being subjected to external force, the locking lever 8 slides axially along the inner wall of the rotating rod 4, while simultaneously compressing the spring 6 inside the rotating rod 4, until the locking lever 8 is fully retracted into the rotating rod 4. Place the take-up roller 10 between the two rotating rods 4. After releasing the take-up roller 10, the spring 6 releases its elastic potential energy, pushing the locking lever 8 to slide outward along the inner wall of the rotating rod 4 and engage with the slots 9 at both ends of the take-up roller 10, completing the installation. Start the motor 5. The output shaft of the motor 5 drives the right rotating rod 4 to rotate. The right rotating rod 4 drives the take-up roller 10 to rotate through the locking lever 8. At the same time, the left rotating rod 4 rotates synchronously with the take-up roller 10, which can be used to wind up the polyester filament. After winding is completed, press the locking lever 8. The locking lever 8 slides inward along the inner wall of the rotating rod 4 and compresses the spring 6, disengaging from the constraint of the slot 9, and the take-up roller 10 can then be wound up. Removed from the rotating rod 4, under normal conditions, the slider 12 is positioned in the middle of the groove 13 under the balancing force of the second spring 7. The guide roller 11 maintains a stable height and angle, and the mother wire passes under the guide roller 11 to form a stable conveying path. When the tension of the mother wire increases, the pressure of the mother wire on the guide roller 11 increases, pushing the second bracket 3 and the slider 12 to slide along the groove 13 in the direction of tension. At this time, the slider 12 compresses the second spring 7 on the corresponding side, and the elastic reaction force of the second spring 7 offsets part of the tension, preventing the mother wire from breaking due to excessive tightness. When the tension of the mother wire decreases, the second spring 7 releases potential energy to push the slider 12 to reset, and the guide roller 11 tightens the mother wire to prevent the mother wire from loosening and causing tangling. The sliding cooperation between the slider 12 and the groove 13 ensures that the guide roller 11 only moves in the front-back direction, avoiding lateral displacement that affects the direction of the mother wire.

[0042] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
