Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of yarn guiding, in particular to a yarn guiding device for an FDY winding machine with a function of preventing yarn winding. Background Technique
[0002] The FDY winding machine is a special equipment for producing fully drawn yarn. The FDY winding machine plays a crucial role in the chemical fiber melt spinning process and can combine the three processes of spinning, drawing, and winding into one step to efficiently produce the drawn finished yarn.
[0003] Existing devices are difficult to adapt to diverse yarn winding. The buffer function is lacking, and the yarn is extremely prone to being over-extruded and stretched during winding. The winding process is unstable throughout, with the yarn frequently running off track and shaking significantly, seriously damaging the winding quality and reducing production efficiency. Content of the Utility Model
[0004] The utility model discloses a yarn guiding device for an FDY winding machine with a function of preventing yarn winding, aiming to solve the technical problems of being difficult to adapt to various yarns, excessive extrusion and stretching during yarn winding, shaking and running off track throughout the process, resulting in a double decline in winding quality and efficiency.
[0005] To achieve the above object, the utility model adopts the following technical scheme: A yarn guiding device for an FDY winding machine with a function of preventing yarn winding, including a control cabinet. One side of the control cabinet is provided with an adjusting assembly. The adjusting assembly includes a limiting cylinder. A left mounting frame is arranged on the side of the limiting cylinder close to the control cabinet. And the outer side of one end of the left mounting frame close to the limiting cylinder is movably connected with a right mounting frame. Connecting frames are fixedly connected to the bottom ends of the right mounting frame and the left mounting frame. Moving wheels are movably connected to the opposite sides of the connecting frames. And the inner side walls of the moving wheels are movably connected with extension cylinders. A connecting piece is fixedly connected to the inner wall of the extension cylinder. An electric telescopic rod is fixedly connected to the inner side of the connecting piece. And one end of the electric telescopic rod is movably connected with the inner wall of one side of the moving wheel close to the control cabinet.
[0006] By setting up a control cabinet and an adjustment component, when the winding machine winds the yarn, the yarn is located between the outside of the limit cylinder and the extension cylinder. Due to the differences in the sizes of different yarns, the electric telescopic rod comes into play at this time. When the yarn is thicker, the electric telescopic rod extends, pushing the moving wheel close to the left mounting frame to move to one side, driving the extension cylinder to extend outward synchronously. During this process, the left mounting frame is stretched, and the moving wheel is movably connected to the connecting frame to ensure the smoothness of the extension action. As the extension cylinder moves outward, the contact area with the yarn increases to meet the winding requirements of thicker yarns. When the yarn is thinner, the double-directional electric telescopic rod contracts, and the moving wheel on one side of the left mounting frame contracts inward, and the extension cylinder also moves inward accordingly, reducing the contact area with the yarn to ensure the effective winding of thin yarns. The movable connection between the moving wheel and the connecting frame, the movable connection between the extension cylinder and the inner wall of the moving wheel, and the limitation of the yarn position by the limit cylinder together ensure that the adjustment component can flexibly adjust the contact area between the extension cylinder and the yarn according to the different yarn sizes. During the process of area adjustment of the extension cylinder, the left mounting frame above moves according to the adjustment of the moving wheel, so that the winding work proceeds smoothly. During the process, it can be applied to the winding of various specifications of yarns, and at the same time provides appropriate buffer force to avoid excessive extrusion or stretching of the yarn, which helps to protect the integrity and quality of the yarn, ensures the stability of the yarn during the winding process, reduces yarn deviation or shaking, and improves the quality and efficiency of winding.
[0007] In a preferred embodiment, a protective frame is fixedly connected to one side of the control cabinet. A yarn bobbin is movably connected to one side of the control cabinet. The yarn bobbin is located at the front end of the protective frame. Symmetrical bottom columns are fixedly connected to one side of the control cabinet. The bottom columns are located below the yarn bobbin. Bottom plates are fixedly connected to the opposite sides of the bottom columns. A guide frame is fixedly connected to the front side of the bottom column at the front end. An adjusting assembly is located between the guide frame and the yarn bobbin. A driving motor is arranged on the side of the adjusting assembly close to the control cabinet. The power output shaft of the driving motor is connected to a driving gear through a coupling. The front side of the driving gear is movably connected to one side of the control cabinet. A linkage gear is movably connected to the outside of the driving gear. The linkage gear is meshed with the driving gear through a first tooth groove. The front end of the linkage gear is movably connected to one side of the control cabinet. A rotating threaded rod is fixedly connected to the inside of the linkage gear. The outside of the rotating threaded rod is movably connected to the inside of a limiting cylinder. A circular hole is formed in the side of the connecting frame close to the driving motor. The rotating threaded rod is located inside the circular hole. A through hole is formed in the side of the connecting frame away from the driving motor. The inside of the through hole is threadedly connected to the outside of the rotating threaded rod. A fixing member is movably connected to the end of the rotating threaded rod away from the control cabinet. An auxiliary round rod is arranged above the rotating threaded rod. One end of the auxiliary round rod is fixedly connected to one side of the control cabinet. Holes are formed in both the right-side frame and the left-side frame. The outside of the auxiliary round rod is movably connected to the inside of the holes. The end of the auxiliary round rod away from the control cabinet is fixedly connected to the front end of the fixing member. A fixing column is fixedly connected to the top end of the bottom plate. The fixing column and the adjusting assembly are arranged side by side. The yarn bobbin is located above the fixing column and the adjusting assembly.
[0008] By being provided with a fixed column, a protective frame, a yarn bobbin, a bottom column, a bottom plate, a guiding frame, a fixing member, a rotating threaded rod, an auxiliary round rod, a linkage gear, a driving gear and a driving motor, during the yarn winding process, the driving motor is started to drive the driving gear to rotate. Since the driving gear meshes with the linkage gear through the first tooth groove, the rotation of the driving gear will drive the linkage gear to rotate synchronously. When the linkage gear rotates, the rotating threaded rod fixed inside it also rotates accordingly. Because the outer side of the rotating threaded rod is movably connected to the inner side of the limiting cylinder, and the outer side of the rotating threaded rod is threadedly connected to the inside of the perforation formed on the side of the connecting frame away from the driving motor, and the rotating threaded rod is located inside the round hole provided on the side of the connecting frame close to the driving motor, the rotation of the rotating threaded rod will cause the limiting cylinder and the adjusting assembly connected thereto to move along the axial direction of the rotating threaded rod. At the same time, the auxiliary round rod plays a role in guiding and stabilizing. One end of the auxiliary round rod is fixed to one side of the control cabinet, and the other end is fixed to the front end of the fixing member, and the holes on the right placing frame and the left placing frame are movably connected to the outer side of the auxiliary round rod, ensuring that the adjusting assembly will not shift during the movement, enabling it to move smoothly along the direction of the auxiliary round rod. When the yarn bobbin rotates for yarn winding, the position of the yarn will constantly change, and the adjusting assembly can timely adjust its position to adapt to the position of the rotating yarn, ensuring that the yarn can be successfully wound within the effective action range of the adjusting assembly, improving the winding quality and efficiency.
[0009] In a preferred solution, an anti-tangling assembly is provided above the fixed column. The anti-tangling assembly includes a retaining frame. The bottom end of the retaining frame is fixedly connected to the top end of the fixed column, and a servo motor is fixedly connected to the inner side of the retaining frame. The power output shaft of the servo motor is connected to a rotating gear through a coupling. The outer side of the rotating gear is movably connected to a gear plate, and the gear plate meshes with the rotating gear through the second tooth groove. The top end of the gear plate is fixedly connected to a plurality of annular members. The inner sides of the annular members are all fixedly connected to movable rods. One end of the movable rod close to the control cabinet is fixedly connected to a yarn coil, and a plurality of buffer springs are fixedly connected to the inner side of the yarn coil. The opposite sides of the buffer springs are all fixedly connected to arc-shaped auxiliary plates, and the outer side of the yarn is in contact with the inner side of the arc-shaped auxiliary plate.
[0010] By setting up an anti-tangling component, when the yarn passes through the adjusting component and enters the anti-tangling component, at this time the yarn passes through the inside of the yarn coil and contacts the inner side of the arc-shaped auxiliary plate. The servo motor starts and drives the rotating gear to rotate. Since the gear plate and the rotating gear are engaged through the second tooth groove, the rotation of the rotating gear will drive the gear plate to move linearly. The multiple annular parts fixedly connected to the top of the gear plate will move along with the movement of the gear plate, and then drive the movable rod fixedly connected to the inner side of the annular part to move. The movement of the movable rod causes the position of the yarn coil connected to it to change. When the yarn has a tendency to be entangled during the winding process, by controlling the rotation direction of the rotating gear by the servo motor, the gear plate drives the yarn coil to adjust its position. In this process, the buffer spring can provide a certain buffer force to prevent the yarn from being overly pulled or squeezed due to position adjustment. The arc-shaped auxiliary plate contacts the outer side of the yarn, and its shape helps to guide the direction of the yarn, enabling the yarn to more smoothly change its winding path along with the position adjustment of the yarn coil, effectively preventing the yarn from being entangled and ensuring the smooth progress of the yarn winding work.
[0011] As can be seen from the above, a yarn guiding device for an FDY winding machine with an anti-yarn entanglement function provided by the present utility model has the technical effects of being applicable to winding various yarns, providing a buffer force, avoiding the yarn from being overly squeezed and stretched, stabilizing the yarn winding process, reducing deviation and shaking, and improving the winding quality and efficiency.

Arc-shaped auxiliary plates 909 are bolted to opposite sides of the buffer springs 908. The outer side of the yarn is in contact with the inner side of the arc-shaped auxiliary plate 909.
[0023] Working principle: When the winding machine winds the yarn, the yarn is located between the outer sides of the limiting cylinder 703 and the extension cylinder 705. Due to the differences in the sizes of different yarns, the electric telescopic rod 707 comes into play at this time. When the yarn is thicker, the electric telescopic rod 707 extends, pushing the moving wheel 704 close to the left mounting frame 708 to move to one side, driving the extension cylinder 705 to extend outward synchronously. During this process, the left mounting frame 708 is stretched. The moving wheel 704 is movably connected to the connecting frame 702 to ensure the smoothness of the extension action. As the extension cylinder 705 moves outward, the contact area with the yarn increases to meet the winding requirements of the thicker yarn. When the yarn is thinner, the electric telescopic rod 707 contracts, and the moving wheel 704 on one side of the left mounting frame 708 contracts inward, and the extension cylinder 705 also moves inward accordingly, reducing the contact area with the yarn to ensure the effective winding of the thin yarn. The movable connection between the moving wheel 704 and the connecting frame 702, the movable connection between the extension cylinder 705 and the inner wall of the moving wheel 704, and the limitation of the yarn position by the limiting cylinder 703 jointly ensure that the adjusting assembly can flexibly adjust the contact area between the extension cylinder 705 and the yarn according to the different yarn sizes. During the process of adjusting the area of the extension cylinder 705, the left mounting frame 708 above moves according to the adjustment of the moving wheel 704, so that the winding work can proceed smoothly; During the yarn winding process, the driving motor 15 starts to drive the driving gear 14 to rotate. Since the driving gear 14 and the linkage gear 13 are engaged through the first tooth groove, the rotation of the driving gear 14 will drive the linkage gear 13 to rotate synchronously. When the linkage gear 13 rotates, the rotating threaded rod 11 fixed inside it also rotates accordingly. Because the outer side of the rotating threaded rod 11 is movably connected to the inner side of the limiting cylinder 703, and is threadedly connected between the outer side of the rotating threaded rod 11 and the inside of the perforation opened on the side of the connecting frame 702 away from the driving motor 15, and the rotating threaded rod 11 is located inside the circular hole provided on the side of the connecting frame 702 close to the driving motor 15, the rotation of the rotating threaded rod 11 will cause the limiting cylinder 703 and the adjusting assembly 7 connected thereto to move along the axial direction of the rotating threaded rod 11. At the same time, the auxiliary round rod 12 plays a role of guiding and stabilizing. One end of the auxiliary round rod 12 is fixed to one side of the control cabinet 1, and the other end is fixed to the front end of the fixing member 10. The holes on the right mounting frame 701 and the left mounting frame 708 are movably connected to the outer side of the auxiliary round rod 12, ensuring that the adjusting assembly 7 will not shift during the movement process and can move smoothly along the direction of the auxiliary round rod 12. When the yarn bobbin 4 rotates to wind the yarn, the position of the yarn will change continuously. The adjusting assembly 7 can adjust the position in a timely manner to adapt to the position of the rotating yarn, ensuring that the yarn can be wound smoothly within the effective action range of the adjusting assembly 7 and improving the quality and efficiency of winding;After the yarn passes through the adjusting component 7, it enters the anti-winding component 9. At this time, the yarn passes through the inside of the yarn coil 907 and contacts the inner side of the arc-shaped auxiliary plate 909. The servo motor 901 is started to drive the rotating gear 902 to rotate. Since the gear plate 904 and the rotating gear 902 are engaged through the second tooth groove, the rotation of the rotating gear 902 will drive the gear plate 904 to perform a linear motion. A plurality of annular members 905 fixedly connected to the top of the gear plate 904 will move along with the movement of the gear plate 904, thereby driving the movable rod 906 fixedly connected to the inner side of the annular member 905 to move. The movement of the movable rod 906 causes the position of the yarn coil 907 connected thereto to change. When the yarn has a tendency to become entangled during the winding process, the rotation direction of the rotating gear 902 is controlled by the servo motor 901, so that the gear plate 904 drives the yarn coil 907 to adjust its position. During this process, the buffer spring 908 can provide a certain buffer force to prevent the yarn from being excessively pulled or squeezed due to the position adjustment. The arc-shaped auxiliary plate 909 contacts the outer side of the yarn, and its shape helps to guide the direction of the yarn, so that the yarn can more smoothly change its winding path along with the position adjustment of the yarn coil 907, effectively preventing the yarn from becoming entangled and ensuring the smooth progress of the yarn winding work.

The substitution may be a substitution of some structures, devices, method steps, or a complete technical solution.
