AI Technical Summary
In existing polyester filament winding devices, the belt drives two winding rollers to rotate, which is prone to slippage, resulting in inconsistent speeds. This affects the uniformity of the polyester filament winding tension and may cause filament breakage or loosening. At the same time, the device cannot ensure that the polyester filament is evenly distributed.
Gear transmission is used instead of belt transmission. The gear system driven by the first servo motor makes the two rollers rotate synchronously. The uniform distribution of polyester filaments is achieved by the cooperation of the reciprocating mechanism and the limiting roller.
It achieves synchronized rotational speed of the rollers, reduces slippage, improves the tension uniformity of polyester filament winding, avoids filament breakage and loose winding, and ensures that polyester filaments are evenly distributed on the winding rollers.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of low-shrinkage polyester filament winding technology, specifically a winding device for low-shrinkage polyester filament. Background Technology
[0002] Low-shrinkage polyester yarn is a "stable" product in the polyester family. Through process innovation, it has solved the problem of high-temperature shrinkage of traditional polyester and plays an important role in the fields of clothing, home furnishing and industry.
[0003] For example, a polyester filament winding device with announcement number "CN214527360U" describes a device where the first winding roller rotates while simultaneously driving a first rotating shaft via a fixed spring and a limiting plate. This first shaft drives a drive pulley, which in turn drives a driven pulley via a belt. The driven pulley then drives a second rotating shaft, which in turn drives a second winding roller via a limiting plate and a fixed spring. This simultaneous rotation of the first and second winding rollers winds the polyester filament, solving the problem of low winding efficiency and inconvenience in existing winding devices. However, the method of driving two winding rollers via a belt is prone to belt slippage, causing inconsistent rotation speeds and affecting the uniformity of the polyester filament winding tension, potentially leading to filament breakage or loosening. Furthermore, this device does not move the polyester filament, making it impossible to distribute it evenly on the winding rollers. Utility Model Content
[0004] The purpose of this invention is to solve the problems of the above-mentioned device, which drives two take-up rollers to rotate via a belt, and the belt is prone to slippage, causing the two take-up rollers to rotate at different speeds, affecting the uniformity of the polyester yarn winding tension, and even causing yarn breakage or loosening. At the same time, the above-mentioned device does not move the polyester yarn, so it cannot make the polyester yarn evenly distributed on the take-up rollers. Therefore, a low-shrinkage polyester yarn winding device is proposed.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design a winding device for low-shrinkage polyester yarn, including a base plate, with a first outer shell, a second outer shell, and a vertical rod fixedly connected to the upper end of the base plate. The first outer shell is provided with a reciprocating mechanism, the second outer shell is provided with a rotating mechanism, and the inner wall of the vertical rod is rotatably connected to two cylinders through bearings.
[0007] Preferably, the end of the cylinder is inserted into the rotating roller, and the inner wall of the rotating roller is machined with a retaining hole.
[0008] Preferably, the rotating mechanism includes a first servo motor, the output shaft of which is fixedly connected to a first gear. The rotating shafts of the first gear are rotatably connected to a second housing via bearings. Both sides of the first gear are meshed with second gears. The rotating shafts of the second gears are fixedly connected to sliding rods. The outer walls of the sliding rods are slidably connected to sliding sleeves. The outer walls of the sliding sleeves are rotatably connected to the second housing via bearings. The rotating shafts of the second gears are rotatably connected to vertical blocks via bearings. The outer walls of the vertical blocks are fixedly connected to the output ends of the electric telescopic rods. The output ends of the electric telescopic rods are slidably connected to the second housing. The electric telescopic rods are fixedly connected to the second housing via bending plates.
[0009] Preferably, the outer wall of the slide rod is slidably connected to the card hole, the end of the slide rod is pressed against the inner wall of the rotating roller, the outer wall of the first servo motor is threadedly connected to the second housing by bolts, and the protrusions on the outer wall of the vertical block are all slidably connected to the second housing.
[0010] Preferably, the reciprocating mechanism includes a second servo motor, the output shaft of which is fixedly connected to a reciprocating lead screw. Both ends of the reciprocating lead screw are rotatably connected to the first housing via bearings. The outer wall of the reciprocating lead screw is slidably connected to a slider, the outer wall of the slider is slidably connected to the first housing, the inner wall of the slider is slidably connected to a sliding frame, and the inner wall of the slider is rotatably connected to two limiting rollers via bearings.
[0011] Preferably, the outer wall of the sliding frame is fixedly connected to the first housing, and the outer wall of the second servo motor is rotatably connected to the first housing by bolts.
[0012] The present invention provides a winding device for low-shrinkage polyester yarn, which has the following advantages: by cooperating with the rotating mechanism and the locking hole, the first servo motor is started. The output shaft of the first servo motor rotates, which drives the first gear to rotate. The rotation of the first gear drives the two second gears to rotate synchronously. The rotation of the second gears drives the slide rod to rotate. The slide rod engages with the locking hole. The rotation of the slide rod drives the rotating roller to rotate. The two rotating rollers rotate to wind up the low-shrinkage polyester yarn. Compared with using a belt to drive the two rotating rollers, the gear cooperation is more precise and less prone to slippage. It ensures that the rotating rollers rotate at the same speed, reduces the impact on the uniformity of the winding tension of the polyester yarn, and reduces the occurrence of yarn breakage or loose winding.
[0013] Through the cooperation of the reciprocating mechanism and the rotating roller, the output shaft of the second servo motor rotates, driving the reciprocating screw to rotate. The rotation of the reciprocating screw drives the slider to move back and forth. The slider's reciprocating movement is limited by the linear motion of the sliding frame and the first outer shell. The reciprocating motion of the sliding frame drives the reciprocating motion of the limiting roller. The limiting roller has a groove in the middle, which can limit the low-shrinkage polyester filament within the groove. At the same time, the arc of the limiting roller is lower in the middle and higher on both sides. Even if the low-shrinkage polyester filament moves out of the groove, it will re-enter the groove due to the arc of the limiting roller, which is higher on both sides and lower in the middle. The reciprocating movement of the limiting roller drives the low-shrinkage polyester filament to move back and forth, which can make the low-shrinkage polyester filament evenly distributed on the rotating roller.

[0029] The rotating mechanism 7 includes a first servo motor 701, the output shaft of which is fixedly connected to a first gear 702. The rotation of the output shaft of the first servo motor 701 drives the first gear 702 to rotate. The rotating shafts of the first gear 702 are rotatably connected to the second housing 4 through bearings. Both sides of the first gear 702 are meshed with second gears 703.

[0035] Working principle:
[0036] When winding low-shrinkage polyester yarn.
[0037] Work process:
[0038] The operator installs the entire device at the low-shrinkage polyester filament production outlet through the threaded holes on the base plate 1. Two low-shrinkage polyester filaments are passed from left to right through the openings of the slider 803 above the two limiting rollers 804, so that the low-shrinkage polyester filaments are placed on the limiting rollers 804. Then, the low-shrinkage polyester filaments are fixed on the rotating rollers 5. Then, the first servo motor 701 and the second servo motor 801 are started simultaneously. The output shaft of the first servo motor 701 rotates, which drives the first gear 702 to rotate. The rotation of the first gear 702 drives the two second gears 703 to rotate synchronously. The rotation of the second gears 703 drives the slide rod 705 to rotate. The slide rod 705 engages with the locking hole 9. The rotation of the slide rod 705 drives the rotating rollers 5 to rotate. The two rotating rollers 5 rotate to wind up the low-shrinkage polyester filaments.
[0039] The output shaft of the second servo motor 801 rotates, driving the reciprocating screw 802 to rotate. The rotation of the reciprocating screw 802 drives the slider 803 to move back and forth. The reciprocating movement of the slider 803 is limited by the linear motion of the sliding frame 805 and the first outer shell 2. The reciprocating movement of the sliding frame 805 drives the reciprocating movement of the limiting roller 804. The limiting roller 804 has a groove in the middle, which can limit the low-shrinkage polyester yarn in the middle groove. At the same time, the arc of the limiting roller 804 is low in the middle and high on both sides. Even if the low-shrinkage polyester yarn moves out of the middle groove, it will re-enter the middle groove due to the arc of the limiting roller 804, which is high on both sides and low in the middle. The reciprocating movement of the limiting roller 804 drives the low-shrinkage polyester yarn to move back and forth, so that the low-shrinkage polyester yarn is evenly distributed on the rotating roller 5. There are baffles on both sides of the rotating roller 5 to prevent the low-shrinkage polyester yarn from winding outside the rotating roller 5. When the winding is completed, the first servo motor 701 and the second servo motor 801 are stopped, and the operator cuts the low-shrinkage polyester yarn.
[0040] The operator starts the lower electric telescopic rod 706, and holds the lower rotating roller 5. The output end of the lower electric telescopic rod 706 retracts. The output end of the electric telescopic rod 706 is limited by the second outer shell 4 and moves linearly, driving the lower vertical block 704 to move to the right, thereby driving the lower second gear 703 to move to the right. Because the first gear 702 is a wide gear, the second gear 703 is always meshed with the first gear 702. The movement of the lower second gear 703 to the right drives the lower slide rod 705 to move to the right. The movement of the slide rod 705 is limited by the sliding sleeve 707 and moves linearly. When the output end of the electric telescopic rod 706 retracts to the limit distance, the electric telescopic rod 706 is a self-locking electric telescopic rod to ensure that when the output end of the electric telescopic rod 706 stops, the position of the second gear 703 is fixed and the slide rod 705 is disengaged from the locking hole 9.
[0041] The worker moves the rotating roller 5 to the right. After the rotating roller 5 is separated from the cylinder 6, the worker can remove the rotating roller 5. The working principle of removing the upper rotating roller 5 is the same as described above. When reinstalling the rotating roller 5, the working principle is the opposite of the above. First, install the upper rotating roller 5, and then install the lower rotating roller 5. After the processing is completed, the worker uses an industrial vacuum cleaner to suck out any lint that may be present in the first outer shell 2 to prepare for the next work. At the same time, the worker performs maintenance and repair on the internal parts through the inspection doors on the first outer shell 2 and the second outer shell 4.
