Abstract
Description
Technical Field
[0001] This application relates to the technical field of textile machinery, and particularly relates to an anti-winding structure for a tensioner. Background Art
[0002] A yarn tensioner is an important device for regulating the tension during yarn unwinding. To produce uniform weft-knitted or warp-knitted fabrics, the knitting yarns must be fed in with uniform tension to ensure uniform yarn consumption. Because when the yarn tension is high, the yarn consumption will decrease, while when the tension is low, the yarn consumption will increase.
[0003] Since some yarns have a certain viscosity, when the viscous yarn enters the tensioner from the bobbin, the yarn will rotate when it is released from the bobbin, and during the rotation process, the yarn is easily stuck and wound around the tensioner. At this time, the yarn is easily broken when pulled later, which has deficiencies. Summary of the Utility Model
[0004] In order to improve the problem of yarn breakage due to winding, this application provides an anti-winding structure for a tensioner.
[0005] An anti-winding structure for a tensioner provided by this application adopts the following technical solution:
[0006] An anti-winding structure for a tensioner includes a yarn unwinding rack, on which a tensioner and a bobbin are arranged. A protective baffle is arranged between the bobbin and the tensioner. The protective baffle is provided with a wire inlet hole, and the axis of the wire inlet hole faces the wire inlet end of the tensioner. The yarn passes through the wire inlet hole on the protective baffle and enters the wire inlet end of the tensioner. A centering component is arranged between the tensioner and the protective baffle, and the centering component is used to adjust the concentricity between the wire inlet hole and the wire inlet end of the tensioner.
[0007] By adopting the above technical solution, the worker first passes the yarn on the bobbin through the wire inlet hole on the protective baffle and into the wire inlet end of the tensioner, and then adjusts the concentricity between the wire inlet hole on the protective baffle and the wire inlet end of the tensioner through the centering component, reducing the contact area between the yarn and the wire inlet hole and the wire inlet end of the tensioner. When the yarn on the bobbin is pulled and rotates, the protective baffle hinders the possibility of the rotating yarn being wound around the tensioner, thereby reducing the possibility of the yarn being broken.
[0008] Optionally, an adjustment plate is provided on the wire pay-off frame, and an adjustment groove is provided on the adjustment plate in the direction from the tensioner to the protective baffle, and a plurality of positioning teeth are evenly arranged in the adjustment groove along its length direction. A locking rod is rotatably provided on the protective baffle, and one end of the locking rod extends into the adjustment groove, and a locking block is provided on the locking rod located in the adjustment groove, and a knob is provided on the end of the locking rod facing away from the locking block, and a torsion spring is provided between the knob and the protective baffle.
[0009] By adopting the above technical solution, before the worker passes the yarn into the wire inlet hole on the protective baffle, the worker turns the knob, the knob drives the torsion spring to deform, and at the same time, the knob drives the locking block to rotate synchronously through the locking rod, and the locking block is separated from the positioning tooth. After the worker pushes the protective baffle to the appropriate position and passes the yarn, the worker loosens the knob, the torsion spring recovers its deformation and drives the locking rod to rotate through the knob, and the locking rod drives the locking block to press against the positioning tooth again, thereby preventing the protective baffle from moving.
[0010] Optionally, the centering assembly includes a slider slidably arranged on the adjustment plate, a sliding member for driving the slider to slide is arranged on the adjustment plate, a lifting plate is vertically slidably arranged on the slider, the tensioner is arranged on the lifting plate, and a lifting member for driving the lifting plate to slide is arranged on the slider.
[0011] By adopting the above technical solution, workers drive the lifting and sliding parts to make the axis of the wire inlet end of the tensioner on the lifting plate coincide with the axis of the wire inlet hole on the protective baffle, thereby reducing the contact area between the yarn and the wire inlet hole and the wire inlet end of the tensioner, and reducing the possibility of the yarn sticking to the tensioner.
[0012] Optionally, the sliding member includes a horizontal screw rod rotatably disposed on the adjustment plate, the axial direction of the horizontal screw rod is perpendicular to the length direction of the adjustment slot, the slider is threadedly engaged with the horizontal screw rod, and a rotating handle is disposed on the horizontal screw rod.
[0013] By adopting the above technical solution, the worker turns the rotating handle, which drives the horizontal screw to rotate, and the horizontal screw drives the slider to slide along the axis of the horizontal screw, so that the wire feed end of the tensioner is close to the wire feed hole on the protective baffle in the horizontal direction.
[0014] Optionally, the lifting member includes a vertical screw arranged on the lifting plate, a guide rod parallel to the axis of the vertical screw is arranged on the lifting plate, the guide rod is slidingly matched with the slider, a lifting cylinder is arranged on the slider, the vertical screw is coaxially slidingly matched with the lifting cylinder, an anti-drop block is threadedly connected to the vertical screw, and the anti-drop block is used to press tightly on the lifting cylinder.
[0015] By adopting the above technical solution, the worker rotates the anti-drop block. Under the restrictive action of the guiding rod, the reaction force of the anti-drop block pressing against the lifting cylinder pushes the lifting plate upward, causing the inlet end of the tensioner on the lifting plate to approach the inlet hole on the protective baffle in the vertical direction, thereby realizing the concentricity adjustment process between the inlet end of the tensioner and the inlet hole on the protective baffle.
[0016] Optionally, an outer guiding cylinder is arranged on the slider, and the guiding rod is in coaxial sliding fit with the outer guiding cylinder.
[0017] By adopting the above technical solution, when the lifting plate rises, the outer guiding cylinder and the guiding rod slide relative to each other, thereby realizing the function of preventing the lifting plate from rotating.
[0018] Optionally, a guiding wire ring is rotatably arranged at the inlet hole on the protective baffle.
[0019] By adopting the above technical solution, when the yarn contacts the guiding wire ring, the torsional force of the rotating yarn drives the guiding wire ring to rotate, reducing the possibility of long-term friction between the yarn and the guiding wire ring at the same position, and reducing the possibility of the yarn being worn and broken.
[0020] Optionally, a polytetrafluoroethylene coating is applied on the guiding wire ring.
[0021] By adopting the above technical solution, the friction force between the guiding wire ring and the yarn is reduced, further reducing the possibility of the yarn being torn off.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The worker first passes the yarn on the bobbin through the inlet hole on the protective baffle into the inlet end of the tensioner, and then adjusts the concentricity between the inlet hole on the protective baffle and the inlet end of the tensioner through the centering assembly, reducing the contact area between the yarn and the inlet hole and the inlet end of the tensioner. When the yarn on the bobbin is pulled and rotates, the protective baffle hinders the possibility of the rotating yarn winding on the tensioner, thereby reducing the possibility of the yarn being torn off;
[0024] 2. Before the worker passes the yarn through the inlet hole on the protective baffle, the worker rotates the knob, and the knob drives the torsion spring to deform. At the same time, the knob drives the locking rod to rotate synchronously through the locking block, and the locking block separates from the positioning teeth. After the worker pushes the protective baffle to a suitable position and passes the yarn, then the worker releases the knob, the torsion spring restores deformation and drives the locking rod to rotate through the knob, and the locking rod drives the locking block to press against the positioning teeth again, thereby preventing the protective baffle from moving;
[0025] 3. The worker rotates the anti-drop block. Under the limiting action of the guide rod, the reaction force of the anti-drop block pressing against the lifting cylinder pushes the lifting plate upward, causing the inlet end of the tensioner on the lifting plate to approach the inlet hole on the protective baffle in the vertical direction, thereby realizing the concentricity adjustment process between the inlet end of the tensioner and the inlet hole on the protective baffle.

Detailed Description of the Embodiment
[0030] The following will Figures 1-3 further describe the present application in detail.
[0031] An embodiment of the present application discloses a tensioner anti-winding structure.
[0032] Referring to Figure 1 , a tensioner anti-winding structure includes a wire pay-off stand 1, an adjusting plate 7 and a bobbin 3 are arranged on the wire pay-off stand 1, a tensioner 2 is arranged on the adjusting plate 7, a protective baffle 4 is arranged between the bobbin 3 and the tensioner 2, an inlet hole 5 is opened on the protective baffle 4, a guiding wire ring 15 is coaxially rotatably arranged at the inlet hole 5 on the protective baffle 4, and a polytetrafluoroethylene coating 16 is coated on the guiding wire ring 15.
[0033] Referring to Figure 1 , Figure 2 and Figure 3, an adjustment groove 8 is provided on the adjustment plate 7 along the direction from the tensioner 2 to the protective baffle 4. A plurality of positioning teeth 9 are uniformly welded in the adjustment groove 8 along its length direction. A vertical locking rod 10 is rotatably connected to the protective baffle 4. One end of the locking rod 10 extends into the adjustment groove 8. A locking block 11 is welded on the locking rod 10 located in the adjustment groove 8. A knob 12 is welded to the end of the locking rod 10 facing away from the locking block 11. A torsion spring 13 is arranged between the knob 12 and the protective baffle 4.
[0034] Referring to Figure 1 , Figure 2 and Figure 3 , the axis of the inlet hole 5 faces the inlet end of the tensioner 2. The yarn passes through the inlet hole 5 on the protective baffle 4 and enters the inlet end of the tensioner 2. An alignment component 6 is arranged between the tensioner 2 and the protective baffle 4. The alignment component 6 is used to adjust the concentricity between the inlet hole 5 and the inlet end of the tensioner 2.
[0035] The worker rotates the knob 12. The rotation of the knob 12 deforms the torsion spring 13. At the same time, the knob 12 drives the locking block 11 to rotate synchronously through the locking rod 10. The locking block 11 rotates and separates from the positioning teeth 9. Then, after the worker pushes the protective baffle 4 to the appropriate position, the worker releases the knob 12. The torsion spring 13 restores its deformation and drives the locking rod 10 to rotate through the knob 12. The locking rod 10 drives the locking block 11 to press against the positioning teeth 9 again.
[0036] At this time, the locking block 11 is located between two adjacent positioning teeth 9. Then, the worker passes the yarn on the bobbin 3 through the inlet hole 5 on the protective baffle 4 and then into the inlet end of the tensioner 2, so that the yarn will not rotate significantly when entering the inlet end of the tensioner 2, avoiding the yarn being wound around the tensioner 2.
[0037] Referring to Figure 1 , Figure 2 and Figure 3 , the alignment component 6 includes a slider 61 slidably arranged on the adjustment plate 7. A sliding member 62 for driving the slider 61 to slide is arranged on the adjustment plate 7. The sliding member 62 includes a horizontal screw rod 621 rotatably connected to the adjustment plate 7. The axis direction of the horizontal screw rod 621 is perpendicular to the length direction of the adjustment groove 8. The slider 61 is in threaded cooperation with the horizontal screw rod 621. A rotating handle 622 is welded to one end of the horizontal screw rod 621.
[0038] Referring to Figure 1 , Figure 2 and Figure 3 , a lifting plate 63 is vertically slidably arranged on the slider 61. The tensioner 2 is welded to the lifting plate 63. A lifting member 64 for driving the lifting plate 63 to slide is arranged on the slider 61. The lifting member 64 includes a vertical screw rod 641 welded to the bottom of the lifting plate 63 and being vertical. A guide rod 642 parallel to the axis of the vertical screw rod 641 is welded to the bottom of the lifting plate 63.
[0039] Refer to Figure 1 、 Figure 2 and Figure 3 At the top of the slider 61, a vertical outer guide cylinder 14 is welded. The guide rod 642 is slidably and coaxially engaged with the outer guide cylinder 14. A vertical lifting cylinder 643 is welded on the slider 61. The vertical screw rod 641 is slidably and coaxially engaged with the lifting cylinder 643. A fall prevention block 644 is threadedly connected to the vertical screw rod 641. The fall prevention block 644 is used to press against the lifting cylinder 643.
[0040] When the worker turns the rotating handle 622, the rotating handle 622 drives the horizontal screw rod 621 to rotate synchronously. Since the slider 61 is slidably engaged with the adjusting plate 7, when the horizontal screw rod 621 rotates and the slider 61 slides a certain distance along the axis direction of the horizontal screw rod 621, the worker rotates the fall prevention block 644. Under the limiting action of the guide rod 642 and the outer guide cylinder 14, the reaction force of the fall prevention block 644 abutting against the top of the lifting cylinder 643 causes the vertical screw rod 641 to slide vertically.
[0041] The vertical screw rod 641 pushes the lifting plate 63 to rise, and the guide rod 642 and the outer guide cylinder 14 slide relative to each other, so that the axis of the wire inlet end of the tensioner 2 on the lifting plate 63 coincides with the axis of the wire inlet hole 5 on the protective baffle 4, thereby reducing the contact area between the yarn and the wire inlet end of the tensioner 2 and the guiding wire loop 15.
[0042] The implementation principle of a tensioner anti-winding structure in an embodiment of the present application is as follows: The worker rotates the knob 12, and the rotation of the knob 12 causes the torsion spring 13 to deform. At the same time, the knob 12 drives the locking rod 10 to rotate synchronously through the locking lever 10. The locking block 11 rotates and separates from the positioning teeth 9. Then, after the worker pushes the protective baffle 4 to a suitable position, the worker releases the knob 12. The torsion spring 13 restores its deformation and drives the locking rod 10 to rotate through the knob 12. The locking rod 10 drives the locking block 11 to re-abut against the positioning teeth 9.
[0043] At this time, the locking block 11 is located between two adjacent positioning teeth 9. Then, the worker passes the yarn on the bobbin 3 through the wire inlet hole 5 on the protective baffle 4 and then penetrates it from the wire inlet end of the tensioner 2, so that the yarn will not rotate significantly when entering the wire inlet end of the tensioner 2, avoiding the yarn from winding around the tensioner 2.
[0044] When the worker turns the rotating handle 622, the rotating handle 622 drives the horizontal screw rod 621 to rotate synchronously. Since the slider 61 is slidably engaged with the adjusting plate 7, when the horizontal screw rod 621 rotates and the slider 61 slides a certain distance along the axis direction of the horizontal screw rod 621, the worker rotates the fall prevention block 644. Under the limiting action of the guide rod 642 and the outer guide cylinder 14, the reaction force of the fall prevention block 644 abutting against the top of the lifting cylinder 643 causes the vertical screw rod 641 to slide vertically.
[0045] The vertical screw rod 641 pushes the lifting plate 63 to rise, and the guide rod 642 slides relative to the outer guide cylinder 14, so that the axis of the wire inlet end of the tensioner 2 on the lifting plate 63 coincides with the axis of the wire inlet hole 5 on the protective baffle 4, thereby reducing the contact area between the yarn and the wire inlet end of the tensioner 2 and the guiding wire loop 15.
[0046] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
