Description

Technical Field

[0001] The utility model relates to the field of textiles, in particular to a winding device for polyester DTY yarns. Background Art

[0002] Polyester DTY yarn, full name polyester low-elastic yarn, is a type of textured yarn of polyester chemical fiber. Polyester DTY yarn uses polyester chips as raw material and is obtained by high-speed spinning to obtain polyester pre-oriented yarn, which is then processed by drawing and false twisting. Its physical properties are high strength and good elasticity. Polyester DTY yarn is widely used in clothing fabrics, household items, decorative materials and other textile fields due to its excellent elasticity and deformation ability, as well as good heat setting and durability. For this reason, the polyester DTY yarn after manufacturing is ensured to be compactly wound on paper rolls or other winding materials in subsequent use to save storage space and transportation costs. At the same time, it is convenient to unwind from the winding material in textile processes such as weaving, printing and dyeing, to ensure the smooth progress of subsequent processing.

[0003] With respect to the above-mentioned related technologies, the inventors found that as the polyester DTY yarn is continuously wound, the diameter of the paper roller used to wind the polyester DTY yarn continues to increase. When the diameter of the paper roller gradually increases and gradually approaches structures such as guide rollers, the winding angle during winding will be too large, which may easily cause the wire to trip and break during the subsequent unwinding process. The wire strips are also easily tangled, and the remaining wire cakes may not be usable. Therefore, reasonably adjusting the spacing between the paper roller and structures such as guide rollers has become an urgent problem to be solved in this field. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a winding device for polyester DTY yarn, which is convenient for reasonably adjusting the distance between the paper roller and structures such as the guide roller to prevent the paper roller from getting too close to the guide roller and other structures when the diameter of the paper roller continues to increase, thereby preventing the winding angle from being too large.

[0005] To solve the above technical problems, the present invention adopts a technical solution: providing a polyester DTY yarn winding device, comprising: a mounting housing and a paper roller winding mechanism connected to one side thereof, a swinging guide mechanism provided on one side of the paper roller winding mechanism, and a guide frame assembly connected to the upper side of the swinging guide mechanism away from the paper roller winding mechanism;

[0006] The swinging guide mechanism includes a supporting rotating shaft connected to the mounting shell, a swinging plate is rotatably connected to the surface of the supporting rotating shaft, a notch is provided on the side of the swinging plate close to the paper roller winding mechanism, a reciprocating guide assembly is provided in the notch, and also includes a telescopic rod assembly for driving the swinging plate to swing.

[0007] By adopting the above technical solution, the paper roller winding mechanism is used for winding the polyester DTY yarn. As the polyester DTY yarn is continuously wound, the diameter of the paper roller gradually increases. At the same time, the telescopic rod assembly drives the swing plate to swing to adjust the distance between the swing plate and the paper roller winding mechanism. The telescopic rod assembly expands and contracts according to the change in the diameter of the paper roller, thereby maintaining a reasonable winding angle. At the same time, it cooperates with the guide frame assembly to further guide and fix the direction of the polyester DTY yarn on the swinging guide mechanism.

[0008] In a preferred example, the present invention can be further configured as follows: the telescopic rod assembly includes an electric push rod and a mounting base rotatably connected to one end thereof, the mounting base is connected to the mounting shell, the other end of the electric push rod is connected to an L-shaped base via a pin shaft, and the L-shaped base is connected to the swing plate.

[0009] By adopting the above technical solution, the electric push rod transmits the thrust to the swing plate, and automatically adjusts the distance between the swing plate and the paper roller winding mechanism as the diameter of the paper roller increases, thereby maintaining a reasonable winding angle and avoiding the occurrence of wire tripping and breakage problems.

[0010] In a preferred example, the present invention can be further configured as follows: a guide rail assembly is connected between the swing plate and the mounting shell, the guide rail assembly includes an arcuate guide rail, a slider adapted thereto is slidably connected to the arcuate guide rail, and the slider is connected to the swing plate.

[0011] By adopting the above technical solution, the arc guide rail adapts to the trajectory of the swing plate during the swinging process and cooperates with the slider to ensure that the swing plate can move smoothly along the arc guide rail during the swinging process, avoiding shaking and deviation during the swinging process, thereby ensuring the stability and uniformity of the polyester DTY yarn during the winding process.

[0012] In a preferred example, the present invention can be further configured as follows: the reciprocating guide assembly includes a reciprocating screw, the surface of the reciprocating screw is rollingly connected to a sliding tube, both ends of the sliding tube are respectively connected to a conical limit plate, and also includes a servo motor connected to the side of the swing plate away from the mounting shell, and the output shaft of the servo motor is connected to one end of the reciprocating screw.

[0013] By adopting the above technical solution, the threaded surface of the reciprocating screw is rollingly connected, ensuring that the reciprocating screw can move back and forth along its axial direction when the reciprocating screw rotates. At the same time, the sliding tube enables the polyester DTY yarn to maintain stable guidance during the winding process, and cooperates with the conical limit disk to guide and limit the polyester DTY yarn, ensuring the stability and uniformity of the polyester DTY yarn during the winding process.

[0014] In a preferred example, the present invention can be further configured as follows: the paper roller winding mechanism includes an air-expanding shaft, a mounting flange and a bearing connected to the inner side thereof; the mounting flange is connected to the mounting shell; the bearing is rollingly connected to one end of the air-expanding shaft; a reduction motor is connected to the side of the mounting shell away from the air-expanding shaft; and the output shaft of the reduction motor is connected to the air-expanding shaft.

[0015] By adopting the above technical solution, the air-expanding shaft fixes the paper roller by inflation, ensuring that the paper roller will not fall off or shake during the winding process. At the same time, it makes replacing the paper roller more convenient and quick, improving the operating efficiency of the equipment. In addition, the air-expanding shaft is precisely driven and controlled by the reduction motor to achieve precise adjustment of the winding speed and direction of the polyester DTY yarn.

[0016] In a preferred example, the present invention can be further configured as follows: the guide frame assembly includes an L-shaped mounting frame, and one inner end of the L-shaped mounting frame is rotatably connected to a guide roller.

[0017] By adopting the above technical solution, the guide roller guides and supports the polyester DTY yarn, reducing the problems of yarn tripping and breakage caused by shaking or deviation.

[0018] In summary, the utility model includes at least one of the following beneficial technical effects of the polyester DTY yarn winding device:

[0019] 1. Through the cooperation of the swing plate and the telescopic rod assembly of the swing guide mechanism, the telescopic rod assembly drives the swing plate to swing to adjust the distance between the swing plate and the paper roller winding mechanism to maintain a reasonable winding angle. At the same time, it cooperates with the guide frame assembly to further guide and fix the direction of the polyester DTY yarn on the swing guide mechanism to avoid the occurrence of yarn tripping and breakage problems.

[0020] 2. By introducing components such as the air-expanding shaft, mounting flange, and bearings, the stability of the paper roll winding mechanism during the polyester DTY yarn winding process has been significantly improved. At the same time, the air-expanding shaft fixes the paper roll by inflating, preventing the paper roll from falling off or shaking during the winding process, and making paper roll replacement more convenient and quick.

[0034] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0035] It should be noted that these drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0036] Reference Figure 1-5, is a polyester DTY yarn winding device disclosed in the present invention, comprising: a mounting shell 1 and a paper roller winding mechanism 20 connected to one side thereof, a swinging guide mechanism 30 is provided on one side of the paper roller winding mechanism 20, a guide frame assembly 40 is connected to the upper side of the swinging guide mechanism 30 away from the paper roller winding mechanism 20, the guide frame assembly 40 comprises an L-shaped mounting frame 41, an inner end of the L-shaped mounting frame 41 is rotatably connected to a guide roller 42, the swinging guide mechanism 30 comprises a supporting rotating shaft 31 connected to the mounting shell 1, a surface of the supporting rotating shaft 31 is rotatably connected to a swinging plate 32, a notch 33 is provided on the side of the swinging plate 32 close to the paper roller winding mechanism 20, a reciprocating guide assembly 34 is provided in the notch 33, and further comprises a telescopic rod assembly 35 for driving the swinging plate 32 to swing, the telescopic rod assembly 35 5 includes an electric push rod 351 and a mounting base 352 rotatably connected to one end thereof. The mounting base 352 is connected to the mounting housing 1. The other end of the electric push rod 351 is connected to an L-shaped base 353 via a pin. The L-shaped base 353 is connected to the swing plate 32. The paper roll winding mechanism 20 fixes the polyester DTY yarn paper roll. During the continuous winding process, the diameter of the paper roll continuously increases. In conjunction with the contraction of the electric push rod 351, the swing plate 32 is driven to swing to adjust the distance between the swing plate 32 and the paper roll winding mechanism 20 to maintain a reasonable winding angle. The swing plate 32 is driven to swing in conjunction with the reciprocating guide assembly 34 to change the path of the polyester DTY yarn entering the paper roll winding mechanism 20. At the same time, the guide roller 42 is used to further guide and fix the polyester DTY yarn on the swing guide mechanism 30 to reduce the occurrence of yarn snags and broken ends.

[0037] A guide rail assembly 36 is connected between the swing plate 32 and the mounting shell 1. The guide rail assembly 36 includes an arcuate guide rail 361. A slider 362 adapted to the arcuate guide rail 361 is slidably connected to the arcuate guide rail 361, and the slider 362 is connected to the swing plate 32. The arcuate guide rail 361 provides a stable and precise motion trajectory for the swing plate 32. The cooperation between the arcuate guide rail 361 and the slider 362 provides a stable and precise motion trajectory for the swing plate 32. This design ensures that the swing plate 32 can move along a predetermined arc path during the swinging process, thereby achieving precise control of the polyester DTY yarn path, and laterally ensuring the stability and uniformity of the polyester DTY yarn during the winding process.

[0038] The reciprocating guide assembly 34 includes a reciprocating screw rod 341, the surface of the reciprocating screw rod 341 is rollingly connected to a sliding tube 342, and both ends of the sliding tube 342 are respectively connected to a conical limit plate 343, and also includes a servo motor 344 connected to the side of the swing plate 32 away from the mounting shell 1, and the output shaft of the servo motor 344 is connected to one end of the reciprocating screw rod 341; driven by the servo motor 344, the sliding tube 342 and the conical limit plate 343 connected to it are driven to roll on the surface of the screw rod, thereby realizing reciprocating motion, so that the swing plate 32 can swing back and forth stably within a certain range, meeting the winding requirements of the polyester DTY yarn, and guiding and limiting the polyester DTY yarn through the conical limit plate 343, preventing equipment damage or polyester DTY yarn breakage caused by excessive swinging.

[0039] The paper roller winding mechanism 20 includes an air-expanding shaft 21, a mounting flange 22 and a bearing 23 connected to the inner side thereof. The mounting flange 22 is connected to the mounting shell 1, and the bearing 23 is rollingly connected to one end of the air-expanding shaft 21. A reduction motor 24 is connected to the side of the mounting shell 1 away from the air-expanding shaft 21, and the output shaft of the reduction motor 24 is connected to the air-expanding shaft 21; the precise matching of the air-expanding shaft 21, the mounting flange 22 and the bearing 23 ensures the stability and smooth rotation of the paper roller during the winding process. At the same time, the air-expanding shaft 21 enables the paper roller to be easily installed and disassembled, and ensures a close fit during the winding process, thereby avoiding slipping or loosening of the polyester DTY yarn during the winding process. In addition, the reduction motor 24 serves as the power source of the paper roller winding mechanism 20. By driving the air-expanding shaft 21 to rotate the paper roller, the winding requirements of polyester DTY yarns of different specifications and materials can be met.

[0040] The implementation principle of this embodiment is as follows: when in use, a suitable winding paper roller is selected according to production requirements, and its quality is ensured to meet the standards. The paper roller is then placed on the air expansion shaft 21 and tightened by the external air pressure device of the air expansion shaft 21 to ensure that the paper roller does not fall off or slip during the winding process, and the air expansion shaft 21 is driven by the reduction motor 24 to drive the paper roller to start rotating. The polyester DTY yarn is then led out of the production equipment and introduced into the paper roller winding mechanism 20 with the help of the guide roller 42 to ensure that the polyester DTY yarn maintains uniform tension during the winding process. At the same time, as the winding paper roller is continuously wound, its diameter continues to increase. At this time, the contraction of the electric push rod 351 drives the swing plate 32 to swing, so as to adjust the distance between the swing plate 32 and the paper roller winding mechanism 20 and maintain a reasonable winding angle, thereby preventing the distance between the paper roller and the sliding tube 342 from being too large and the winding angle from being too large.
