This utility model utilizes a first motor, an upper cleaning roller, a lower cleaning roller, a belt, and a pulley to clean dust from the surface of the yarn, leaving the yarn surface cleaner and free of dust residue, allowing it to be used directly, reducing processing costs.

[0003] However, the upper and lower cleaning rollers in this utility model are fixed in position, i.e., they are always attached together, making it difficult for yarn to pass between them. Furthermore, the upper and lower cleaning rollers in this utility model are connected via a pulley and belt drive, so they rotate in the same direction. Furthermore, because the upper and lower cleaning rollers are located above and below the yarn, respectively, they exert forces in opposite directions on the yarn, making it easy for the yarn to bend during transport.

[0008] The lifting structure is used to drive the upper cleaning roller to move up and down, and the lifting structure includes a second brake servo motor, a top plate and a lifting rod, the top plate is fixedly connected between the top ends of the first fixed plate and the second fixed plate, a cavity is opened inside the top plate, and a linkage rod extending horizontally front and back is rotatably connected in the cavity through a bearing, and two second driving gears are fixedly sleeved on the outside of the linkage rod, and the first fixed plate and the second fixed plate are provided with a slide groove extending longitudinally up and down on the opposite sides, and a screw rod extending in the same direction is rotatably connected in the slide groove through a bearing, the top end of the screw rod penetrates into the cavity and is fixed with a second driven gear meshing with the second driving gear, and sliders for inserting into the slide groove and moving up and down along the slide groove are fixed at the front and rear ends of the lifting rod, and the slider is sleeved on the outside of the screw rod in a threaded connection manner, and two extension rods are fixed to the bottom end of the lifting rod, and the bottom ends of the two extension rods are fixed with collars, and the two collars are respectively rotatably sleeved on the outside of the first transition rod and the second transition rod through bearings, and the second brake servo motor is installed on the outer wall of the top plate to drive the linkage rod to rotate;

[0009] The control box is mounted on the rear outer side wall of the first fixed plate, and is electrically connected to the first brake servo motor and the second brake servo motor via a PLC controller, and realizes the positioning parking of the first brake servo motor through programming;

[0010] The cam is secured to the bottom of the second support rod and is secured to the bottom of the second support rod. The cam is secured to the bottom of the second support rod and is secured to the bottom of the second support rod. The shaft is set and located directly below the upper cleaning roller, and the lower cleaning roller includes a lower center rod and two lower shaft rods, and the two lower shaft rods are respectively integrally formed at the center positions of the front and rear ends of the lower center rod, and the center positions of the two ends of the lower shaft rods opposite to each other are respectively integrally formed with a lower rotating rod and a lower connecting rod, the lower rotating rod is inserted into the first notch in a matching connection manner, and is rotatably connected to the first lower rotating shaft through a pin shaft, the lower connecting rod is inserted into the first connecting groove in a matching connection manner, and is fixedly connected to the second lower rotating shaft by a bolt and a nut, and the outer parts of the upper center rod and the lower center rod are both provided with sponge covers in an interference fit manner, and the two sponge covers fit each other.

[0011] By adopting the above technical solution, when the yarn needs to be passed between the upper and lower cleaning rollers, the upper cleaning roller is first moved upward by the lifting structure, thereby forming a gap between the upper and lower sponge sleeves, allowing the yarn to pass more easily between the two sponge sleeves. After the yarn has passed between the two sponge sleeves, the upper cleaning roller is then moved downward by the lifting structure to reset, so that the two sponge sleeves are aligned with each other. When the winding part is activated to transport the yarn from left to right, the upper and lower cleaning rollers are simultaneously rotated slowly and uniformly by the rotating structure. The lower cleaning roller rotates slowly and uniformly counterclockwise, and the sponge sleeve on it applies a leftward force to the yarn. The upper cleaning roller rotates slowly and uniformly clockwise, and the sponge sleeve on it applies a leftward force to the yarn. During the process of transporting the yarn from left to right, both sponge sleeves apply a leftward force to the yarn, which not only improves the cleaning effect of the sponge sleeves on the yarn, but also further tightens the yarn and prevents it from bending. The sponge sleeves rotate slowly, so they do not affect the transportation of the yarn.

[0012] The lifting mechanism drives the upper cleaning roller up and down as follows: The control box activates the second brake servo motor, which drives the linkage rod to rotate. The linkage rod rotates the second driving gear on it. The second driving gear rotates the meshing second driven gear. The second driven gear rotates the screw rod fixed to it. The rotation of the screw rod drives the slider to move up and down along the screw rod and the guide slot. The slider drives the lifting rod up and down. The lifting rod drives the two extension rods to move up and down simultaneously. The two extension rods drive the two collars to move up and down simultaneously, and the two collars drive the first and second transition rods to move up and down simultaneously. The first and second transition rods drive the upper cleaning roller up and down. When the first and second transition rods move upward, the first plug rod moves out of the first plug slot and the second plug rod moves out of the second plug slot. When the first and second transition rods move downward, the first plug rod inserts into the first plug slot and the second plug rod inserts into the second plug slot.

[0013] The operating principle of the rotating structure driving the upper and lower cleaning rollers to rotate in opposite directions simultaneously is as follows: The control box activates the first brake servo motor, which drives the first lower rotating shaft to rotate counterclockwise. The first lower rotating shaft drives the lower cleaning roller to rotate counterclockwise. The lower cleaning roller drives the second lower rotating shaft to rotate counterclockwise. The second lower rotating shaft drives the first driving gear to rotate counterclockwise. The first driving gear drives the first driven gear meshed with it to rotate clockwise. The first driven gear drives the second upper rotating shaft to rotate clockwise. The second upper rotating shaft drives the upper cleaning roller to rotate clockwise. The upper cleaning roller drives the first upper rotating shaft to rotate clockwise, thereby achieving simultaneous counterclockwise rotation of the upper and lower cleaning rollers.

[0014] When the sponge cover needs to be replaced after prolonged use, remove the nuts and bolts between the second transition rod and the upper connecting rod. At this point, since the upper rotating rod fits into the second notch and is pivotally connected to the first transition rod via a pin, the upper cleaning roller can rotate on the first transition rod. Turn the upper cleaning roller leftward to move the upper connecting rod out of the second connecting slot, thereby separating the upper cleaning roller from the second transition rod. Because the sponge cover is highly elastic, stretch it to remove it from the upper center rod and replace it with a new one. Similarly, remove the nuts and bolts between the second lower rotating shaft and the lower connecting rod. At this point, since the lower rotating rod fits into the first notch and is pivotally connected to the first lower rotating shaft via a pin, the lower cleaning roller can rotate on the first lower rotating shaft. Turn the lower cleaning roller leftward to move the lower connecting rod out of the first connecting slot, thereby separating the lower cleaning roller from the second lower rotating shaft. Because the sponge cover is highly elastic, stretch it to remove it from the lower center rod and replace it with a new one.

[0015] The upper cleaning roller of this utility model can move up and down, making it easier for workers to pass yarn between the upper and lower cleaning rollers. Both the upper and lower cleaning rollers exert a force on the yarn opposite to the direction of yarn transmission, preventing yarn bending and improving cleaning efficiency. Furthermore, the sponge cover is easy and convenient to replace.

[0016] The utility model is further configured as follows: two limiting rings are fixedly sleeved on the exterior of the upper center rod and the lower center rod, and the sponge sleeve is clamped between the two limiting rings.

[0017] By adopting the above technical solution, the setting of the limiting ring can prevent the sponge cover from deviating on the upper center rod and the lower center rod due to friction force, or even falling off the upper center rod and the lower center rod.

[0018] A further configuration of the present invention is that the outer diameter of the limiting ring is smaller than that of the sponge sleeve.

[0019] By adopting the above technical solution, when the two sponge sleeves are fitted together, a gap is retained between the limiting rings on the upper and lower sides to prevent the limiting rings from being damaged by collision.

[0020] Further configuration of the utility model: the outer sleeve of the cleaning part is provided with a dust cover, and the dust cover is spliced ​​by two cover bodies arranged symmetrically front and back, the bottom end of the cover body is integrally formed with a slide bar, and the top end of the horizontal plate is provided with a guide groove extending horizontally front and back, and the slide bar is inserted into the guide groove in a matching connection manner and slides back and forth along the guide groove.

[0021] By adopting the above technical solution, when the utility model is in an idle state, the two covers are moved toward each other, so that the two covers are spliced ​​together to form a dust cover installed outside the cleaning part, thereby preventing external dust from accumulating on the sponge cover. In addition, the cover moves on the horizontal plate by moving the slide bar in the guide groove, and the movement of the cover is more stable.

[0022] A further configuration of the present invention is that a handle is fixed on the outer side wall of the cover body.

[0023] By adopting the above technical solution, the staff can move the cover more conveniently through the handle.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] A yarn winding machine with an upper cleaning roller that can move up and down facilitates the worker to pass the yarn between the upper and lower cleaning rollers. Both the upper and lower cleaning rollers exert a force on the yarn opposite to the direction of yarn transmission, preventing yarn bending and improving cleaning efficiency. The sponge cover is also easy and convenient to replace. BRIEF DESCRIPTION OF THE DRAWINGS

Two second driving gears 30 are fixedly sleeved on the exterior of the linkage rod 29. Vertically extending slots 31 are defined on opposing sides of the first and second fixed plates 5, 6. A lead screw 32, extending in the same direction as the lead screw 32, is rotatably connected to the slots 31 via a bearing. The top end of the lead screw 32 extends into the cavity 28 and is secured with a second driven gear 33 that meshes with the second driving gear 30. Sliders 34 are fixed to the front and rear ends of the lifting rod 27. These slides 34 are threadedly mounted on the exterior of the lead screw 32. Two extension rods 35 are fixed to the bottom end of the lifting rod 27. The bottom ends of the two extension rods 35 are fixed with collars 36. The two collars 36 are respectively rotatably mounted on the outside of the first transition rod 15 and the second transition rod 20 via bearings. The second brake servo motor 25 is mounted on the outer wall of the top plate 26 to drive the linkage rod 29 to rotate.

[0048] The control box 7 is mounted on the rear outer wall of the first fixed plate 5. The control box 7 is electrically connected to the first brake servo motor 8 and the second brake servo motor 25 via a PLC controller. Programming is used to achieve a positional stop of the first brake servo motor 8 (i.e., whenever the first brake servo motor 8 is turned off, the first rotating shaft body 14 remains in a state where the top side of the first insertion slot 16 extends through the first rotating shaft body 14, and the second rotating shaft body 19 remains in a state where the top side of the second insertion slot 22 extends through the second rotating shaft body 19). Using a PLC controller to achieve a positional stop of the first brake servo motor 8 is a mature prior art technique and will not be described in detail in this embodiment.

[0049] The upper cleaning roller is coaxially arranged with the first upper rotating shaft and the second upper rotating shaft and is located directly below the lifting rod 27 .

[0050] The upper cleaning roller includes an upper center rod 37 and two upper shaft rods 38. The two upper shaft rods 38 are integrally formed at the center of the front and rear ends of the upper center rod 37. An upper rotating rod 39 and an upper connecting rod 40 are integrally formed at the center of the opposing ends of the upper shaft rods 38. The upper rotating rod 39 is inserted into the second notch 18 in a mating manner and is rotationally connected to the first transition rod 15 via a pin. The upper connecting rod 40 is inserted into the second connecting groove 24 in a mating manner and is fixedly connected to the second transition rod 20 via a bolt and nut.

[0051] The lower cleaning roller is arranged concentrically and coaxially with the first lower rotating shaft 9 and the second lower rotating shaft 10 and is located directly below the upper cleaning roller. The lower cleaning roller includes a lower center rod 41 and two lower shaft rods 42. The two lower shaft rods 42 are respectively integrally formed at the center positions of the front and rear ends of the lower center rod 41. A lower rotating rod 43 and a lower connecting rod 44 are respectively integrally formed at the center positions of the opposite ends of the two lower shaft rods 42. The lower rotating rod 43 is inserted into the first notch 11 in a mating connection manner and is rotatably connected to the first lower rotating shaft 9 via a pin. The lower connecting rod 44 is inserted into the first connecting groove 13 in a mating connection manner and is fixedly connected to the second lower rotating shaft 10 via a bolt and nut.

[0052] The outer parts of the upper center rod 37 and the lower center rod 41 are both sleeved with sponge sleeves 45 in an interference fit manner. The two sponge sleeves 45 are fitted to each other.

[0053] Additionally, two retaining rings 46 are fixedly mounted on the exterior of the upper center rod 37 and the lower center rod 41, and the sponge cover 45 is clamped between the two retaining rings 46. The retaining rings 46 prevent the sponge cover 45 from deflecting on the upper center rod 37 and the lower center rod 41 due to friction, or even falling off the upper center rod 37 and the lower center rod 41.

[0054] The outer diameter of the limiting ring 46 is smaller than the sponge cover 45. When the two sponge covers 45 are attached to each other, a gap is left between the limiting rings 46 on the upper and lower sides to avoid collision and damage between the limiting rings 46.

[0055] The outer sleeve of the cleaning part is provided with a dust cover. The dust cover is formed by splicing two cover bodies 47 that are symmetrically arranged front and back. A slide bar 48 is integrally formed at the bottom end of the cover body 47. A guide groove 49 extending horizontally front and back is provided at the top of the horizontal plate 1. The slide bar 48 is inserted into the guide groove 49 in a matching connection manner and slides back and forth along the guide groove 49. When the utility model is in an idle state, the two cover bodies 47 are moved toward each other so that the two cover bodies 47 are spliced ​​into a dust cover arranged on the outside of the cleaning part to prevent external dust from accumulating on the sponge cover 45. The cover body 47 is moved on the horizontal plate 1 by moving the slide bar 48 in the guide groove 49, and the movement of the cover body 47 is more stable. A handle 50 is fixed to the outer wall of the cover body 47. The staff can move the cover body 47 more conveniently through the handle 50.

[0056] Working principle: When the yarn needs to pass between the upper and lower cleaning rollers, the upper cleaning roller is first moved upward by the lifting structure, thereby forming a gap between the upper and lower sponge sleeves 45, allowing the yarn to pass more easily between the upper and lower sponge sleeves 45. After the yarn passes between the two sponge sleeves 45, the upper cleaning roller is again moved downward and reset by the lifting structure, so that the two sponge sleeves 45 fit together. When the winding part 4 starts to transport the yarn from left to right, the upper and lower cleaning rollers are driven to rotate slowly and uniformly at the same time by the rotating structure. The lower cleaning roller rotates slowly and uniformly counterclockwise, and the sponge sleeve 45 on it exerts a leftward force on the yarn. The upper cleaning roller rotates slowly and uniformly clockwise, and the sponge sleeve 45 on it exerts a leftward force on the yarn. During the process of transporting the yarn from left to right, both sponge sleeves 45 exert a leftward force on the yarn. On the one hand, this can improve the cleaning effect of the sponge sleeves 45 on the yarn, and on the other hand, it can further tighten the yarn to prevent the yarn from bending. Furthermore, the rotation speed of the sponge cover 45 is slow and will not affect the transportation of the yarn.

[0057] The lifting mechanism drives the upper cleaning roller up and down as follows: The control box 7 activates the second brake servo motor 25, which drives the linkage rod 29 to rotate. The linkage rod 29 rotates the second driving gear 30 on it. The second driving gear 30 rotates the second driven gear 33 meshing with it. The second driven gear 33 rotates the screw rod 32 fixed to it. The rotation of the screw rod 32 drives the slider 34 to move up and down along the screw rod 32 and the guide slot 31. The slider 34 drives the lifting rod 27 up and down. The lifting rod 27 drives the two extension rods 35 up and down simultaneously. The two extension rods 35 drive the two collars 36 to move up and down simultaneously. The two collars 36 drive the first transition rod 15 and the second transition rod 20 up and down simultaneously. The first transition rod 15 and the second transition rod 20 drive the upper cleaning roller up and down. As the first and second transition rods 15 and 20 move upward, the first insertion rod 17 moves out of the first insertion slot 16, and the second insertion rod 23 moves out of the second insertion slot 22. When the first transition rod 15 and the second transition rod 20 move downward, the first plug-in rod 17 is inserted into the first plug-in groove 16 , and the second plug-in rod 23 is inserted into the second plug-in groove 22 .

[0058] The working principle of the rotating structure driving the upper and lower cleaning rollers to rotate in opposite directions simultaneously is as follows: the first brake servo motor 8 is started via the control box 7, and the first brake servo motor 8 drives the first lower rotating shaft 9 to rotate counterclockwise. The first lower rotating shaft 9 drives the lower cleaning roller to rotate counterclockwise. The lower cleaning roller drives the second lower rotating shaft 10 to rotate counterclockwise. The second lower rotating shaft 10 drives the first driving gear 12 to rotate counterclockwise. The first driving gear 12 drives the first driven gear 21 engaged therewith to rotate clockwise. The first driven gear 21 drives the second upper rotating shaft to rotate clockwise. The second upper rotating shaft drives the upper cleaning roller to rotate clockwise. The upper cleaning roller drives the first upper rotating shaft to rotate clockwise. This achieves simultaneous counterclockwise rotation of the upper and lower cleaning rollers.

[0059] When the sponge cover 45 needs to be replaced after prolonged use, remove the bolts and nuts between the second transition rod 20 and the upper connecting rod 40. At this point, since the upper rotating rod 39 is inserted into the second notch 18 in a mating connection and is pivotally connected to the first transition rod 15 via a pin, the upper cleaning roller can rotate on the first transition rod 15. Rotating the upper cleaning roller to the left will remove the upper connecting rod 40 from the second connecting groove 24, thereby separating the upper cleaning roller from the second transition rod 20. Since the sponge cover 45 is highly elastic, stretch it to remove it from the upper center rod 37 and replace it with a new sponge cover 45. Similarly, remove the bolts and nuts between the second lower rotating shaft 10 and the lower connecting rod 44. At this point, since the lower rotating rod 43 is inserted into the first notch 11 in a mating connection and is pivotally connected to the first lower rotating shaft 9 via a pin, the lower cleaning roller can rotate on the first lower rotating shaft 9. Rotating the lower cleaning roller to the left will remove the lower connecting rod 44 from the first connecting groove 13. Thereby the lower cleaning roller is separated from the second lower rotating shaft 10. Because sponge cover 45 itself has high elasticity, stretching sponge cover 45 is taken off from lower center bar 41 and the sponge cover 45 that replaces is got final product.

[0060] The upper cleaning roller of this utility model can move up and down, making it easier for workers to pass the yarn between the upper and lower cleaning rollers. Both the upper and lower cleaning rollers exert a force on the yarn opposite to the direction of yarn transmission, preventing yarn bending and improving cleaning efficiency. Furthermore, the sponge cover 45 is easy and convenient to replace.
