[0031] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0032] The following is combined with Figure 1-Figure 5 This embodiment is described in further detail.

[0033] like Figure 1As shown, a yarn winding device of a silk winding machine in this embodiment includes a base plate 100, and a first support plate 110 and a second support plate 120 are respectively provided on the upper end surface of the base plate 100 and at both ends thereof, and a rotatable first protrusion 200 and a second protrusion 210 are respectively provided on the side walls of the first support plate 110 and the second support plate 120, and a winding roller 130 for winding the yarn is provided between the first protrusion 200 and the second protrusion 210, and mounting portions 131 for the first protrusion 200 and the second protrusion 210 to be clamped are respectively provided at both ends of the winding roller 130, and a disassembly assembly for disassembling and assembling the winding roller 130 between the first support plate 110 and the second support plate 120 is provided on the base plate 100, and a winding assembly for driving the winding roller 130 to wind the yarn is provided on the first support plate 110, and a cavity 221 is further provided in the base plate 100, and a driving assembly for evenly winding the yarn around the winding roller 130 is provided in the cavity 221.

[0034] In this embodiment, the first protrusion 200 and the second protrusion 210 are respectively inserted into the corresponding mounting portion 131 by disassembling the assembly, so that the winding roller 130 is installed between the first support plate 110 and the second support plate 120. After the yarn is wound around the winding roller 130, the winding roller 130 is driven to rotate by the winding assembly, so that the winding of the yarn by the winding roller 130 is realized. When the winding roller 130 winds up the yarn, the winding assembly in the cavity 221 drives the yarn to reciprocate along the axial direction of the winding roller 130, so that the yarn can be evenly wound around the winding roller 130. Compared with the existing ones, the yarn winding device of this kind of winding machine can avoid the yarn being not evenly wound around the winding roller 130 during actual use, resulting in poor winding effect of the winding roller 130 on the yarn.

[0035] Among them, when the winding roller 130 completes winding of the yarn, the first protrusion 200 and the second protrusion 210 can be slid out of the corresponding mounting portion 131 through the disassembly and assembly assembly, thereby releasing the installation of the winding roller 130 between the first support plate 110 and the second support plate 120, thereby facilitating the staff to remove the winding roller 130 from between the first support plate 110 and the second support plate 120 and replace it with a new winding roller 130 for subsequent use.

[0036] When it is actually used, the first support plate 110 is fixedly mounted on the base plate 100 .

[0037] like Figure 1-3 As shown, in this embodiment, a driving cavity 301 communicating with the cavity 221 is provided in the first support plate 110, a rotatable first convex rod 310 is provided in the driving cavity 301, one end of the first convex rod 310 passes through the first support plate 110 and is connected to the first convex block 200, and a worm gear 311 is sleeved on the first convex rod 310;

[0038] The winding assembly includes a worm 320 disposed in the cavity 221 and one end of which extends into the driving cavity 301. The worm 320 is rotatable and meshed with the worm wheel 311. The worm 320 drives the worm wheel 311 to rotate, so that the winding roller 130 can wind up the yarn.

[0039] In this embodiment, by setting the driving cavity 301, the first protruding rod 310, the worm wheel 311 and the worm 320, the first protruding rod 310 is rotatably installed in the driving cavity 301 through the bearing seat, so that the first protruding block 200 is rotatably installed on the first supporting plate 110, the worm wheel 311 is fixedly installed on the first protruding rod 310, and the worm 320 is rotatably installed on the bottom plate 100 of the cavity 221 through the bearing seat, and the second protruding rod is fixedly installed on the second protruding block 210, and the second protruding rod is rotatably installed on the second supporting plate 120 through the bearing seat. When the first protruding block 200 and the second protruding rod 210 are respectively inserted into the corresponding mounting parts 131, when the worm 320 rotates, the worm 320 drives the worm wheel 311 to rotate, and the rotation of the worm wheel 311 drives the first protruding rod 310 to rotate, so that the first protruding block 200 drives the winding roller 130 to rotate and winds the yarn;

[0040] The first protrusion 200 and the second protrusion 210 are both square, and the shape of the mounting portion 131 is also square. When the first protrusion 200 and the second protrusion 210 are respectively inserted into the mounting portions 131 at both ends of the winding roller 130, the first protrusion 200 rotates to drive the winding roller 130 to rotate;

[0041] In actual use, a motor 150 for driving the worm 320 to rotate is fixedly mounted on the upper end surface of the first support plate 110 , and an output shaft of the motor 150 is connected to the upper end of the worm 320 , so that the worm 320 can be driven to rotate by the motor 150 .

[0042] like Figure 1-4 As shown, in this embodiment, a mounting groove 401 is provided in the bottom plate 100, a connecting groove 101 connected to the mounting groove 401 is opened on the upper end surface of the bottom plate 100 along its length direction, and a supporting block 410 with one end passing through the connecting groove 101 and extending into the mounting groove 401 is provided on the second supporting plate 120;

[0043] The disassembly assembly includes a screw rod 420 disposed in the installation groove 401 and having one end threadedly passing through the support block 410 . The screw rod 420 is rotatably disposed to rotate and drive the second support plate 120 to move, thereby realizing the disassembly and assembly of the winding roller 130 between the first protrusion 200 and the second protrusion 210 .

[0044] In this embodiment, by setting the mounting groove 401, the connecting groove 101, the support block 410 and the screw rod 420, the support block 410 is fixedly mounted on the second support plate 120, the support block 410 passes through the connecting groove 101 and is inserted into the mounting groove 401, and the two ends of the screw rod 420 are rotatably mounted in the mounting groove 401 through the bearing seat, and the opposite side walls of the mounting groove 401 limit the opposite side walls of the support block 410. When the screw rod 420 rotates, the screw rod 420 and the support block 410 are threaded. The support block 410 drives the second support plate 120 to slide along the installation groove 401. When the support block 410 drives the second support plate 120 away from the first support plate 110, the second protrusion 210 on the second support plate 120 slides out from the mounting portion 131 on the winding roller 130. At this time, the installation of the winding roller 130 between the first support plate 110 and the second support plate 120 is released, so that after the winding roller 130 completes the winding of the yarn, a new winding roller 130 can be replaced for subsequent use.

[0045] When the mounting portion 131 at one end of the winding roller 130 is inserted into the first protrusion 200, the second support plate 120 is driven to approach the first support plate 110 by the screw rod 420, so that the second protrusion 210 is inserted into the mounting portion 131 at the other end of the winding roller 130, thereby realizing the installation of the winding roller 130 between the first support plate 110 and the second support plate 120;

[0046] In actual use, one end of the screw rod 420 is extended out of the base plate 100, and a hand-cranked wheel 160 for driving the screw rod 420 to rotate is fixedly installed on the extended end of the screw rod 420. The hand-cranked wheel 160 makes it easier to drive the screw rod 420 to rotate, making it more convenient to use.

[0047] like Figure 1-5 As shown, in this embodiment, a slide groove 102 communicating with the cavity 221 is provided on the upper end surface of the bottom plate 100 along its length direction;

[0048] The driving assembly includes a circular plate 230 which is arranged in the cavity 221 and can rotate. A vertical rod 231 is provided on the upper end surface of the circular plate 230 and at the edge. A slidable movable plate 240 is provided in the cavity 221. A movable groove 501 for inserting one end of the vertical rod 231 is provided on the side wall of the movable plate 240 along its extension direction. The movable plate 240 is also provided with a movable block 140 with one end extending out of the slide groove 102. The movable block 140 is provided with a through hole 141 for the yarn to pass through. The rotation of the circular plate 230 is used to drive the movable block 140 on the movable plate 240 to slide along the slide groove 102, so that the yarn passing through the through hole 141 is evenly wound on the winding roller 130. A rotating member for driving the circular plate 230 to rotate is also provided at the lower end of the worm 320.

[0049] In this embodiment, by setting the slide groove 102, the circular plate 230, the vertical rod 231, the movable plate 240, the movable groove 501, the movable block 140, the through hole 141 and the rotating member, the vertical rod 231 is fixedly installed on the circular plate 230, and the movable block 140 is fixedly installed on the movable plate 240. When one end of the yarn passes through the through hole 141 and is wound around the winding roller 130, the circular plate 230 is driven to rotate by the rotating member, and the vertical rod 231 on the circular plate 230 rotates along the circumference of the circular plate 230. The vertical rod 231 can drive the movable plate 240 to slide back and forth in the cavity 221. The movement of the movable plate 240 can drive the movable block 140 to reciprocate along the slide groove 102, so that the yarn on the movable block 140 reciprocates along the winding roller 130, and the yarn is evenly wound around the winding roller 130.

[0050] Among them, by setting the moving groove 501, the side walls of the cavity 221 opposite to each other slide and fit with the side walls of the moving plate 240. When the circular plate 230 drives the vertical rod 231 to rotate, the vertical rod 231 slides in the moving groove 501, so that the vertical rod 231 drives the moving plate 240 to slide along the slide groove 102, so that the yarn can be evenly wound on the winding roller 130.

[0051] In actual use, a block 260 is fixedly installed on the opposite side wall of the cavity 221 along its length direction, and a slot 502 for the corresponding block 260 to be inserted into is opened on the opposite side wall of the movable plate 240. By inserting the block 260 into the slot 502, the movable plate 240 is limited, so that the sliding of the movable plate 240 in the cavity 221 is more stable, thereby achieving a better winding effect of the yarn on the winding roller 130.

[0052] like Figure 1-3 As shown, in this embodiment, a first pulley 250 is provided on the lower end surface of the circular plate 230;

[0053] The rotating member includes a second pulley 321 disposed on the worm 320 , and a transmission belt 251 is sleeved between the first pulley 250 and the second pulley 321 . The worm 320 rotates to drive the first pulley 250 to rotate, thereby realizing the rotation of the circular plate 230 .

[0054] In this embodiment, by setting the first pulley 250, the second pulley 321 and the transmission belt 251, the first pulley 250 is fixedly installed on the lower end surface of the circular plate 230 and is located at the center position, and the second pulley 321 is fixedly installed at the lower end of the worm 320. When the worm 320 rotates, the worm 320 drives the second pulley 321 to rotate, and the second pulley 321 can drive the first pulley 250 to rotate through the transmission belt 251, so that the first pulley 250 drives the circular plate 230 to rotate;

[0055] In actual use, the lower end surface of the first pulley 250 is fixedly mounted with a mounting shaft 252 , and the mounting shaft 252 is rotatably mounted on the bottom wall of the cavity 221 through a bearing seat, thereby realizing the rotatable installation of the circular plate 230 and the first pulley 250 in the cavity 221 .

[0056] Working principle: first, one end of the yarn is passed through the through hole 141 and wound around the winding roller 130. When the motor 150 drives the worm 320 to rotate, the first protrusion 200 drives the winding roller 130 to wind up the yarn. At this time, the rotation of the worm 320 can drive the circular plate 230 to rotate, thereby driving the moving block 140 to reciprocate along the slide groove 102, that is, the yarn is reset along the winding roller 130, so that the rotation of the winding roller 130 can evenly wind the yarn around the winding roller 130. When the winding roller 130 completes the winding of the yarn, by rotating the hand wheel 160, the second support plate 120 begins to move away from the first support plate 110, and the second protrusion 210 slides out from the mounting portion 131 on the winding roller 130, thereby releasing the installation of the winding roller 130. At this time, the staff can replace the new winding roller 130 to continue winding the yarn.
