[0032] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] like Figures 1 to 8 As shown, a yarn winding device of the present invention comprises a frame 1, a winding roller 11 and a thread guiding mechanism, and also comprises a clamping mechanism, a thread cutting mechanism and a gluing mechanism arranged on the frame 1.

[0034] The winding roller 11 can be detachably mounted on the frame 1, and the frame 1 is provided with a mounting opening 100 for installing and removing the winding roller 11. The clamping mechanism is used to clamp and fix the winding roller 11 so that the axis of the winding roller 11 is colinear with the clamping center of the clamping mechanism. The lead mechanism is used to guide the yarn 12 to be wound to the outside of the winding roller 11. The cutting mechanism is used to cut the yarn 12 after the yarn 12 on the outside of the winding roller 11 is wound. The gluing mechanism is used to stick the end of the yarn 12 to be wound on the newly replaced winding roller 11 to achieve the connection between the yarn 12 and the new winding roller 11.

[0035] The wire guide mechanism includes a guide rod 13 and a guide block 14 . The guide rod 13 is disposed on the frame 1 , and the length direction of the guide rod 13 is consistent with the axial direction of the winding roller 11 . The guide block 14 slides with the guide rod 13 along the length direction of the guide rod 13 .

[0036] Specifically, Figures 1 to 6 As shown, when the yarn 12 is wound, the end of the yarn 12 is passed through the guide block 14 and fixed on the winding roller 11. At this time, the yarn 12 can be gradually wound on the outside of the winding roller 11 through the rotation of the winding roller 11. During this process, the guide block 14 can reciprocate along the length direction of the guide rod 13, so that the yarn 12 is evenly wound on the winding roller 11, ensuring that the thickness of the yarn 12 wound on the winding roller 11 is uniform, thereby ensuring the winding effect.

[0037] The clamping mechanism includes multiple groups of clamping components, which are arranged in a circumferential array along the winding roller 11. Each group of clamping components includes a clamping roller 21, an elastic member 22, a U-shaped mounting frame 23 and a sliding rod 24. The clamping roller 21 is rotatably arranged on the U-shaped mounting frame 23. One end of the sliding rod 24 is connected to the U-shaped mounting frame 23, and the other end slides with the frame body 1 along its own length direction. The elastic member 22 is arranged between the U-shaped mounting frame 23 and the frame body 1, so that the circumferential side of the clamping roller 21 is tightly attached to the circumferential side of the winding roller 11, wherein the elastic member 22 can be set as a spring. One of the clamping rollers 21 in the same clamping mechanism is a self-driving structure, so that it can actively rotate around its own axis.

[0038] Specifically, Figures 1 to 5 As shown, when installing the winding roller 11, the winding roller 11 is installed at the center of multiple groups of clamping assemblies. At this time, multiple clamping rollers 21 will be kept in close contact with the side walls of the winding roller 11 under the action of the corresponding elastic members 22, so that the axis of the winding roller 11 is in line with the clamping center of the clamping mechanism. As the thickness of the yarn 12 wound on the outside of the winding roller 11 gradually increases, each clamping roller 21 will move along the length direction of the corresponding slide bar 24, and the elastic member 22 will continue to be compressed to accumulate force. In this process, the circumference of the clamping roller 21 is always in close contact with the circumference of the winding roller 11 to ensure the clamping effect of the clamping mechanism on the winding roller 11. After the installation and fixation of the winding roller 11 is completed, the self-driven clamping roller 21 is rotated around its own axis. At this time, through the contact between the clamping roller 21 and the winding roller 11, the winding roller 11 can be driven to rotate to wind the yarn 12.

[0039] The tangent mechanism includes a cutting shaft 31 and a driving member 1. The cutting shaft 31 is rotatably mounted on a U-shaped mounting frame 23 in one group of clamping assemblies. The circumferential side of the cutting shaft 31 is in contact with the circumferential side of the winding roller 11, and there is a gap between the cutting shaft 31 and the clamping roller 21 for the yarn 12 to pass through. The yarn 12 to be wound first passes through the guide block 14, then passes through the gap between the clamping roller 21 and the cutting shaft 31, and is finally wound on the outside of the winding roller 11. As the amount of yarn 12 wound on the outside of the winding roller 11 gradually increases, the yarn 12 can be tangent to the side wall of the cutting shaft 31 and enter into the fixed groove 311 provided on the cutting shaft 31. A cutting knife 32 is provided on the outside of the cutting shaft 31, and the driving member 1 is used to drive the cutting knife 32 to move to cut the yarn 12.

[0040] Specifically, Figures 1 to 7As shown, when winding the yarn 12, the end of the yarn 12 needs to pass through the guide block 14, then pass through the gap between the clamping roller 21 and the cutting shaft 31, and finally be fixed on the winding roller 11. At this time, through the cooperation of the winding roller 11 and the guide block 14, the yarn 12 can be evenly wound on the outside of the winding roller 11. During this process, the yarn 12 will reciprocate along the axial direction of the cutting shaft 31 in the gap. As the amount of yarn 12 wound on the outside of the winding roller 11 gradually increases, the clamping roller 21 and the cutting shaft 31 will gradually move away from the clamping center. At the same time, the inclination angle of the portion of the yarn 12 to be wound between the guide block 14 and the winding roller 11 will gradually decrease, so that the portion of the yarn 12 in the gap and the side wall of the cutting shaft 31 are aligned. The distance will gradually decrease until the yarn 12 is tangent to the side wall of the cutting shaft 31. At this time, as the guide block 14 continues to move, the yarn 12 will move along the axial direction of the cutting shaft 31 along the side wall of the cutting shaft 31, so that the yarn 12 can enter the fixed groove 311 provided on the cutting shaft 31 to fix the yarn 12. At this time, the cutting knife 32 is driven to move by the driving member 1. Since one end of the yarn 12 is fixed on the winding roller 11 and the other end is fixed in the fixed groove 311, the yarn 12 is in a tensioned state, which makes it easier to cut the yarn 12. After cutting the yarn 12, the winding roller 11 that has been wound up is removed from the installation port 100, and a new winding roller 11 is installed to continue winding the yarn 12.

[0041] The gluing mechanism includes a film 41, a moving frame 42 and a second driving member. The film 41 is arranged at one end of the moving frame 42 facing the cutting shaft 31. The second driving member is used to drive the moving frame 42 to move toward the cutting shaft 31 to stick the film 41 to the outside of the cutting shaft 31.

[0042] Specifically, Figures 2 to 8As shown, after the yarn 12 is cut by the tangent mechanism, the end of the yarn 12 to be wound is still fixed in the fixed groove 311. In this embodiment, the cutting shaft 31 is a self-driving structure. After the yarn 12 is cut, the cutting shaft 31 starts to rotate around its own axis, driving the fixed end of the yarn 12 to rotate. When the end of the yarn 12 is toward the moving frame 42, the moving frame 42 is driven by the second driving member to move in the direction close to the cutting shaft 31 until the end of the moving frame 42 contacts the side wall of the cutting shaft 31, and then the moving frame 42 is driven by the second driving member to gradually move away from the cutting shaft. 31. During this process, the film 41 pasted on the end of the movable frame 42 will be transferred to the side wall of the cutting shaft 31 and attached to the end of the yarn 12. At this time, the cutting shaft 31 begins to reverse around its own axis. When the film 41 contacts the side wall of the newly replaced winding roller 11, the film 41 will be pasted to the outside of the winding roller 11 and the end of the yarn 12 will be fixed on the winding roller 11 to achieve the connection between the yarn 12 and the new winding roller 11. At this time, the yarn 12 can continue to be wound by rotating the winding roller 11, which reduces the labor cost in the winding process and improves the winding efficiency.

[0043] It should be noted that the adhesion force between the film 41 and the circumferential side of the cutting shaft 31 is smaller than the adhesion force between the film 41 and the circumferential side of the winding roller 11, so that during the rotation of the cutting shaft 31, the film 41 adhered to the cutting shaft 31 can be smoothly transferred to the winding roller 11 after contacting the winding roller 11, thereby fixing the end of the yarn 12 to be wound on the new winding roller 11, realizing the connection between the yarn 12 and the new winding roller 11. At this time, the yarn 12 can continue to be wound by rotating the newly replaced winding roller 11.

[0044] In some embodiments, the clamping mechanism also includes a connecting rod structure arranged between two adjacent groups of clamping components, so that multiple groups of clamping components can be moved synchronously in a direction close to or away from the clamping center. A turntable 15 is rotatably provided on the frame body 1, and a plurality of arc-shaped slide grooves 151 are provided on the turntable 15 along its circumference. The connecting rod structure includes two connecting rods 25, and the ends of the two connecting rods 25 close to each other are hinged through a hinge shaft 1, and the hinge shaft 1 is rotatably connected to the U-shaped mounting frame 23. The other ends of the two connecting rods 25 are respectively hinged to the ends of the connecting rod 25 in the connecting rod structure adjacent to the corresponding side through a hinge shaft 2, and the hinge shaft 2 is slidably matched with the arc-shaped slide groove 151.

[0045] Specifically, Figures 1 to 4As shown, as the thickness of the yarn 12 wound on the outside of the winding roller 11 gradually increases, the clamping roller 21 will move in the direction away from the clamping center, and cause the hinge shaft 1 to move in the direction away from the clamping center. At this time, under the transmission of the connecting rod 25, the hinge shaft 2 will slide along the arc-shaped slide groove 151, that is, under the action of the connecting rod structure, multiple groups of clamping mechanisms can be synchronously moved in the direction away from the clamping center, so that in the process of winding the yarn 12, the axis of the winding roller 11 can always be colinear with the clamping center of the clamping mechanism, avoiding the deviation of the winding roller 11, ensuring the clamping effect of the clamping mechanism on the winding roller 11, and then ensuring the winding effect of the yarn 12.

[0046] In some embodiments, an annular groove is opened on the circumferential side of the cutting shaft 31, and a plurality of baffle rods 312 are arranged in the annular groove. The plurality of baffle rods 312 are arranged at intervals along the circumference of the cutting shaft 31. The fixed groove 311 is the space formed between the baffle rods 312 and the annular groove. A plurality of cutting knives 32 are provided, and are respectively arranged corresponding to the plurality of baffle rods 312. After the cutting knife 32 moves and cuts the yarn 12 fixed in the fixed groove 311, the thread ends of the yarn 12 to be wound are still fixed in the fixed groove 311.

[0047] Specifically, Figures 2 to 7 As shown, as the thickness of the yarn 12 wound on the outside of the winding roller 11 gradually increases, the yarn 12 can be tangent to the side wall of the cutting shaft 31. At this time, the guide block 14 continues to move, and the yarn 12 will move along the axial direction of the cutting shaft 31 along the side wall of the cutting shaft 31. When the yarn 12 moves to the annular groove, the yarn 12 will enter the fixed groove 311 formed by the stop rod 312 and the annular groove, and the yarn 12 is fixed by the fixed groove 311, so that the yarn 12 stops moving along the axial direction of the cutting shaft 31. At this time, the yarn 12 on the outside of the winding roller 11 is wound After the winding is completed, the driving part is started, driving the cutting knife 32 to move along the axial direction of the cutting shaft 31, so that the cutting knife 32 and the blocking rod 312 move closely and alternately. At this time, the cutting knife 32 can cut the yarn 12 fixed on the inner side of the blocking rod 312. After the cutting is completed, the end of the wound yarn 12 will be detached from the cutting shaft 31, and the winding roller 11 that has been wound can be removed. At the same time, the end of the yarn 12 to be wound is still fixed in the fixing groove 311, which is convenient for the subsequent fixing of the end of the yarn 12 to be wound on the new winding roller 11 through the gluing mechanism.

[0048] In some embodiments, the gluing mechanism also includes a feeding assembly for feeding the film 41. The feeding mechanism includes two material rollers 43 and a feeding belt 44. One end of the feeding belt 44 is wound on one of the material rollers 43, and the other end is wrapped around the end of the movable frame 42 and wound on the other material roller 43. The rotation of the feeding belt 44 is realized by the rotation of the two material rollers 43. The films 41 are pasted on the feeding belt 44 at intervals, and the film 41 is double-sided tape.

[0049] Specifically, Figures 2 to 8 As shown, when the movable frame 42 is driven by the driving member 2 to move in the direction close to the cutting shaft 31, the film 41 adhered to the feeding belt 44 can be adhered to the side wall of the cutting shaft 31. Release films are provided on both sides of the feeding belt 44, so that the film 41 can be smoothly removed from the feeding belt 44. After the movable frame 42 is reset by the driving member 2, one of the material rollers 43 rotates to discharge the material, and the other material roller 43 rotates to collect the material, driving the feeding belt 44 to rotate, so that the new feeding belt 44 part with the film 41 adhered to it replaces the original feeding belt 44 part, so as to realize the continuous feeding of the film 41. The entire feeding process does not require manual participation, which reduces the labor intensity of employees and is conducive to improving work efficiency.

[0050] In some embodiments, each clamping roller 21 has an inclined surface at one end facing the mounting opening 100 , and the inclined surface gradually inclines toward the clamping center of the clamping mechanism in a direction away from the mounting opening 100 .

[0051] Specifically, Figures 1 to 6 As shown, in the initial state, the clamping roller 21 is maintained in the initial position under the action of the elastic member 22. At this time, the distance between the clamping roller 21 and the clamping center is small. When the winding roller 11 is installed from the installation port 100, the end of the winding roller 11 will contact the ends of multiple clamping rollers 21 at the same time. When the winding roller 11 continues to be pushed in the direction close to the clamping roller 21, the clamping roller 21 can be moved away from the clamping center under the action of the inclined surface until the winding roller 11 can be inserted into the center of the multiple clamping rollers 21, so that the axis of the winding roller 11 is in line with the clamping center, and the side walls of each clamping roller 21 are in close contact with the side walls of the winding roller 11. By setting the inclined surface on the clamping roller 21, it is convenient to install the winding roller 11.

[0052] In some embodiments, a lead-in coil 16 is further provided on the frame 1, and a plurality of yarns 12 to be wound pass through the lead-in coil 16 and are guided to different winding rollers 11 through a plurality of lead-in mechanisms.

[0053] Specifically, Figures 2 to 4As shown, a plurality of winding devices are installed on the frame 1, which can simultaneously wind up a plurality of yarns 12 on a plurality of winding rollers 11, thereby improving the winding efficiency. In this embodiment, four winding devices are described as an example, and the lead coil 16 is installed at the center of the four winding devices. The four yarns 12 all pass through the lead coil 16 and are wound up on the corresponding winding roller 11 through the corresponding lead-in mechanism. By setting the lead coil 16, mutual interference between the yarns 12 to be wound can be avoided, so that the yarns 12 can be smoothly wound up on the corresponding winding roller 11.
