Abstract
Description
Technical Field
[0001] This utility model relates to the field of textile machinery manufacturing technology, and in particular to a winding device for preventing yarn overturning. Background Technology
[0002] In recent years, with the rapid development of my country's textile industry and the upgrading of consumption, the demand for mid-to-high-end clothing has been increasing. Therefore, people are constantly improving the quality of textile yarns to enhance the quality of finished garments and meet market demands. Traditional yarn winding is mainly based on the principle of mechanical transmission, using the high-speed rotation of spindles to wind the yarn. However, in the operation of existing winding machines, due to the unavoidable gaps and friction between mechanical parts, the yarn is subjected to inertial forces and reverse torque, resulting in reverse rotation. In actual production, yarn reversal has always been a major problem plaguing the textile industry. Moreover, the transmission systems of some equipment are quite complex, and energy loss and instability are prone to occur during power transmission, further exacerbating the possibility of yarn reversal. Furthermore, different yarns of different materials and thicknesses have different physical properties. For example, some yarns have high elasticity and store a lot of elastic potential energy during winding. When the operating state of the winding equipment fluctuates slightly, this elastic potential energy may be released, causing the yarn to reverse. In addition, the wire may be affected by uneven tension during the conveying process. Excessive or insufficient local tension will damage the stability of the wire during winding and cause reversal problems.
[0003] Once the yarn reverses direction, it will inevitably affect the twist of the yarn. If the twist of the yarn is uneven, the quality of the yarn will drop sharply, resulting in problems such as uneven thickness and inconsistent strength. This will affect subsequent textile processing and even directly affect the quality of the finished garment, making it impossible to guarantee the uniformity, feel, appearance and physical properties of the garment. On the other hand, the yarn reversal will also increase the breakage rate. Dealing with tangles and breaks caused by reversal requires machine stoppage and manual intervention, which greatly reduces the overall production efficiency and increases the cost of manual maintenance and repair.
[0004] Therefore, the textile industry urgently needs a device that can overcome the limitations of existing technology and reliably and efficiently prevent yarn reversal under various working conditions, ensuring the uniformity of the yarn and improving the quality of textiles, thereby fundamentally controlling and avoiding various problems caused by reversal during winding. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this utility model provides a winding device that prevents wire from flipping, effectively solving technical problems such as wire harnesses easily flipping, shifting, crossing, and uneven tension during the winding process. It achieves uniform arrangement and precise guidance of the wire harness, while adapting to changes in wire harness diameter, ensuring the stability and reliability of the winding process, and greatly improving the performance of the winding device and product quality.
[0006] This utility model achieves the above-mentioned technical objectives through the following technical means.
[0007] A winding device for preventing wire rollover includes a first frame and a turret roller. The turret roller is provided with a rotatable winding shaft for winding a wire bundle. The turret roller is mounted on the first frame via a rotary device. The device also includes a planar wire guide device. The first frame is provided with a groove. The planar wire guide device is movably mounted on the groove and is driven to move within the groove by a straight-line mechanism.
[0008] The planar wire guiding device includes a sleeve, a planar pressure roller, and a wire guiding mechanism; one end of the sleeve is located in a groove and connected to a straight-moving mechanism; the two ends of the sleeve support the planar pressure roller, the axis of the planar pressure roller is parallel to the axis of the sleeve, and the planar pressure roller is in contact with or has a gap with the outer side of the wire harness loop formed on the winding shaft; the wire guiding mechanism is axially movable and installed on the outside of the sleeve, and the wire guiding mechanism is provided with several staggered wire guiding rollers for uniformly guiding the wire harness on the winding shaft.
[0009] Furthermore, the gap between the planar pressure roller and the outer side of the wire harness loop is less than half the width of the wire harness and greater than the thickness of the wire harness.
[0010] Furthermore, the outer ring of the sleeve is provided with a guide groove, a lead screw is installed inside the sleeve, a slider is installed on the lead screw, the slider is located in the guide groove, the power unit drives the lead screw to rotate, so that the slider moves back and forth in the guide groove, and the direction of the slider's movement is parallel to the axial direction of the winding shaft; the wire guide mechanism is installed on the slider, and through the reciprocating movement of the wire guide mechanism, it is used to evenly arrange the wire bundle in the axial direction of the winding shaft.
[0011] Furthermore, the wire guiding mechanism includes a first idler assembly, a second idler assembly, and a third idler assembly. The wire harness passes through the first idler assembly, the second idler assembly, and the third idler assembly in sequence before being wound onto the winding shaft. The axes of several guide rollers in the first idler assembly are perpendicular to the axis of the winding shaft, the axes of several guide rollers in the third idler assembly are parallel to the axis of the winding shaft, and the axes of several guide rollers in the second idler assembly are inclined to the axes of several guide rollers in the first idler assembly, in order to prevent the wire harness from flipping when entering the third idler assembly.
[0012] Furthermore, the angle between the axis of the plurality of guide rollers in the second idler assembly and the axis of the plurality of guide rollers in the first idler assembly is an acute angle.
[0013] Furthermore, the third guide roller assembly includes two first guide rollers and a third guide roller arranged side by side; the third guide roller is the wire roller output by the wire guiding mechanism, and the third guide roller is a guide roller with inverted conical shape on both sides, used to prevent the output wire bundle from deviating.
[0014] Furthermore, it also includes a wire guide device, a tensioning wheel, a tension detection device, and a fourth idler assembly. The wire harness is drawn into the planar wire guide device through the wire guide device and the fourth idler assembly. The tension detection device is used to detect the tension during the wire harness conveying process. The tensioning wheel is used to tension the wire harness.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. The anti-rollover winding device of this utility model uses a second idler roller assembly in a planar wire guide device whose axis is inclined to the axis of several guide rollers in the first idler roller assembly, and the angle between them is acute. The wire bundle passes through the first idler roller assembly, the second idler roller assembly, and the third idler roller assembly in sequence before being wound onto the winding shaft. The inclined arrangement of the second idler roller assembly can prevent the wire bundle from rolling over when entering the third idler roller assembly. This is because the inclined axis design of the second idler roller assembly provides a gradual angle transition for the wire bundle, allowing it to smoothly adjust its direction before entering the third idler roller assembly, thereby ensuring the neat arrangement of the wire bundle and improving the winding quality. Without the second idler roller assembly, when the wire bundle directly enters the third idler roller assembly from the first idler roller assembly, the angle change is too large, and the wire bundle is very likely to roll over once before being output from the third idler roller assembly, resulting in uneven winding and an uneven surface after winding.
[0017] 2. The anti-rollover winding device of this utility model, by setting a movable wire guide mechanism, uses the reciprocating movement of the slider to drive the wire guide mechanism to move along the axial direction of the winding shaft, so that the wire bundle output from the third guide roller can be evenly wound around the winding area of the winding shaft. Since the direction of movement of the slider is parallel to the axial direction of the winding shaft, during the winding process, the reciprocating movement of the slider driven by the screw makes the winding trajectory of the wire bundle on the winding shaft present an axial reciprocating pattern, avoiding the wire bundle from concentrating in a local area, thereby improving the stability and reliability of winding.
[0018] 3. The anti-rollover winding device of this utility model includes a third roller assembly comprising two first guide rollers and a third guide roller arranged side by side. The third guide roller is a guide roller with inverted conical sides. The inverted conical design of the third guide roller helps guide the wire bundle and prevents the wire bundle from deviating during output. This is because when the inverted conical guide roller contacts the wire bundle, its gradually contracting shape can generate a guiding force towards the center of the wire bundle, keeping the wire bundle on the predetermined winding path, thereby further improving the winding accuracy and quality. At the same time, the staggered distribution of the guide rollers on the wire mechanism ensures that the wire bundle can be accurately guided during the winding process, avoiding wire bundle deviation and crossing, and improving the neatness and aesthetics of the winding.
[0019] 4. In the anti-rollover winding device of this utility model, as the wire harness winds around the winding shaft, the diameter of the winding shaft gradually increases. At this time, the cylinder drives the planar wire guide device to move within the groove, thereby adjusting the gap between the planar pressure roller and the outer side of the wire harness loop, ensuring that the planar pressure roller is always in contact with the outer side of the wire harness loop or maintains an appropriate gap. This helps maintain the pressure of the planar pressure roller on the wire harness, allowing the wire harness to be tightly and evenly wound on the winding shaft during the winding process, avoiding loose winding or wire harness unwinding, and improving the stability and quality of winding.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] like Figure 1 and Figure 2 As shown, the anti-rollover winding device of this utility model includes a first frame 1, a planar wire guide device 23, and a turret roller 24. The turret roller 24 is equipped with a self-rotating winding shaft 16 for winding the wire bundle. The bottom of the winding shaft 16 is connected to a drive motor, and the winding shaft 16 rotates under the drive of the drive motor. The turret roller 24 is mounted on the first frame 1 via a rotary device; the rotation of the turret roller 24 and the self-rotation of the winding shaft 16 are existing technologies and are commonly used in existing winding machines. The first frame 1 is provided with a slide groove 3, and the planar wire guide device 23 is movably mounted on the slide groove. The planar wire guide device 23 is driven to move within the slide groove by a cylinder; in some embodiments, a hydraulic cylinder can also be used for driving, and the hydraulic cylinder is connected to the planar wire guide device 23 via a tension rod.
[0034] like Figure 2 and Figure 3 As shown, the planar wire guiding device 23 includes a sleeve 5, a planar pressure roller 12, and a wire guiding mechanism. The sleeve 5 extends to support the roller shaft of the planar pressure roller 12, which can rotate around the roller shaft. The axis of the planar pressure roller 12 is parallel to the axis of the sleeve 5 and also parallel to the axis of the winding shaft 16. The planar pressure roller 12 contacts or has a certain gap with the outer side of the wire harness loop formed on the winding shaft 16 to prevent the wire harness from turning over during winding, causing uneven winding and an uneven surface after winding. The gap is generally less than half the width of the wire harness and greater than the thickness of the wire harness. One end of the sleeve 5 is provided with a base 4 connected to a cylinder, which can drive the sleeve 5 to move within the slide groove 3. The wire guiding mechanism has several staggered wire guiding rollers to guide the wire harness to the winding shaft 16.
[0035] like Figure 2 and Figure 3 As shown, the outer ring of the sleeve 5 is provided with a guide groove 6. A lead screw 7 is installed inside the sleeve, and a slider 10 is installed on the lead screw 7. The slider 10 is located in the guide groove 6. The motor drives the lead screw 7 to rotate, causing the slider 10 to reciprocate within the guide groove 6. The direction of movement of the slider 10 is parallel to the axial direction of the winding shaft 16. The wire guide mechanism is installed on the slider 10. Through the reciprocating movement of the wire guide mechanism, it is used to evenly distribute the wire bundle along the axial direction of the winding shaft 16.
[0036] like Figure 3 As shown, the sleeve 5 has outwardly extending support frames 13 fitted onto both ends, and the roller shaft of the flat pressure roller 12 is supported between the two support frames 13. Each support frame 13 is fixed to the sleeve 5 by a locking screw. Loosening the locking screw and manually rotating the support frame 13 can adjust the gap between the flat pressure roller 12 and the wire harness loop on the winding shaft 16. Figure 4 and Figure 5As shown, the wire guiding mechanism includes a first idler assembly, a second idler assembly, and a third idler assembly. The wire harness passes through the first idler assembly, the second idler assembly, and the third idler assembly sequentially before being wound onto the winding shaft 16. The axes of the guide rollers in each idler assembly are parallel. The axes of several guide rollers in the first idler assembly are perpendicular to the axis of the winding shaft 16, the axes of several guide rollers in the third idler assembly are parallel to the axis of the winding shaft 16, and the axes of several guide rollers in the second idler assembly are inclined to the axes of several guide rollers in the first idler assembly. The wire harness entering the first idler assembly is basically parallel to the axis of the winding shaft 16 or has a small angle with the axis of the winding shaft 16, while the wire harness entering the third idler assembly is perpendicular to the axis of the winding shaft 16. This facilitates winding on the winding shaft 16. However, without the second idler assembly, the wire harness would easily flip over and be output from the third idler assembly due to the large change in angle. Therefore, the inclined arrangement of the second idler assembly can prevent the wire harness from flipping when entering the third idler assembly.
[0037] In this embodiment, the first idler roller assembly includes two first guide rollers 8, the axes of which are perpendicular to the axis of the winding shaft 16, and the two first guide rollers 8 are staggered in the mounting plane; the second idler roller assembly includes two second guide rollers 9, such as... Figure 4 and Figure 5 As shown, the second guide roller 9 is located diagonally below and to the right of the first idler roller assembly. The angle between the axis of the second guide roller 9 and the axis of the winding shaft 16 is 60 degrees (the angle projected onto the plane of the first frame 1). The two second guide rollers 9 are staggered in the mounting plane. The third idler roller assembly includes two first guide rollers 8 and one third guide roller 11. The axes of the first guide rollers 8 and the third guide roller 11 in the third idler roller assembly are parallel to the axis of the winding shaft 16. The third idler roller assembly is located diagonally below and to the left of the second idler roller assembly, and directly below the first idler roller assembly. The two first guide rollers 8 and the one third guide roller 11 of the third idler roller assembly are arranged side by side. The third guide roller 11 is the output roller of the entire wire guiding mechanism. The third guide roller 11 is a guide roller with inverted conical shapes on both sides, which ensures that the wire bundle output by the third guide roller 11 will not deviate. Figure 7 As shown, in this embodiment, the wire harness sequentially passes through two first guide rollers 8 in the first idler roller assembly, two second guide rollers 9, and two first guide rollers 8 in the third idler roller assembly before being output by the third guide roller 11 and entering the winding shaft 16. The diameter of the second guide roller 9 is smaller than the diameter of the first guide roller 8.
[0038] Since the direction of movement of slider 10 is parallel to the axial direction of winding shaft 16, during the winding process, slider 10 is driven to move back and forth by lead screw, so the wire mechanism moves back and forth in the axial direction, and the wire output by third guide roller 11 can be evenly wound on the winding area of winding shaft 16.
[0039] like Figure 2 and Figure 6 As shown, in this embodiment, the anti-rollover winding device of the present invention further includes a wire guide device 21, a tensioning wheel 18, a tension detection device 22, and a fourth idler roller assembly, arranged in the following order according to the wire feeding sequence: wire guide device 21, tension detection device 22, fourth idler roller assembly, flat wire guide device 23, and winding shaft 16. The second frame 2 is used to place the wire guide device 21 and the tension detection device 22.
[0040] The lead-in device 21 is used to pull the wire on the raw material roll. The lead-in device includes several wire pulleys 14, which are generally arranged in a straight line. After one end of the wire is pulled out from the raw material roll, it is wound in an S-shape on the several wire pulleys 14 arranged in a straight line, and then passes through the tensioning wheel 18 and the tension detection device 22 before entering the fourth idler roller assembly. The tension detection device 22 includes a force-measuring wire pulley 15 and a sensor. The force-measuring wire pulley 15 is supported on the second frame 2, and the sensor is used to detect the tension on the force-measuring wire pulley 15.
[0041] like Figure 6 As shown, the fourth guide roller assembly includes two fourth guide rollers 25 and two fifth guide rollers 26. The two fourth guide rollers 25 are located to the lower right of the force-measuring wheel 15, and are staggered (i.e., diagonally arranged) within the mounting plane. The two fifth guide rollers 26 are located to the lower left of the two fourth guide rollers 25, and can be seen in the figure to be directly below the force-measuring wheel 15. The two fifth guide rollers 26 are arranged in a straight line. The angle between the axis of the fifth guide roller 26 and the axis of the force-measuring wheel 15 is 90 degrees. The angle between the axis of the fourth guide roller 25 and the axis of the force-measuring wheel 15 is 45 degrees.
[0042] In use, the wire harness is first threaded: one end of the wire from the raw material roll is pulled out and guided in an S-shape on the wire wheel 14 of the wire guide device 21, then sequentially threaded through the tension wheel 18, the force measuring wheel 15, and the fourth guide roller, then sequentially passed through the planar guide device 23, and finally wound onto the winding shaft 16. While the winding shaft 16 is rotating, the slider 10 is driven by the lead screw to move back and forth, causing the wire guide mechanism to move back and forth along the axial direction. This allows the wire harness output from the third guide roller 11 to be evenly wound around the winding area of the winding shaft 16. The parallel pressure roller 12 maintains a constant pressure on the winding shaft 16. As the wire harness winds, the diameter of the winding shaft 16 gradually increases. At this time, the planar guide device 23 is driven by a cylinder to move within the groove, ensuring that the parallel pressure roller 12 is always in contact with the outer side of the wire harness coil or has a certain gap.
[0043] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
[0044] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
