Description

Technical Field

[0001] The invention belongs to the technical field of yarn winding, in particular to a yarn winding method and a device. Background Art

[0002] A yarn winder is a mechanical device used to wind yarn into rolls. It is commonly used in the textile industry. Its main function is to neatly wind the processed yarn into rolls for easy storage and transportation. The winder can adjust the winding tension, speed and winding diameter to adapt to different types of yarn. The working process of the yarn winder usually includes: transferring the yarn from a spinning machine or other equipment to the winder.

[0003] A patent application with publication number CN118954190A discloses a yarn winding machine and a winding method, which dynamically adjusts the yarn winding process through a correction mechanism. That is, when the yarn is thrown out too much due to centrifugal force, the follower ring can be pressed and corrected by applying pressure to the follower ring and through the resistance between the follower ring and the magnetic field, so as to avoid more yarn being thrown out to cause knotting and the breakage of the upper yarn. In addition, the oscillation component can generate oblique shaking to resist the vertical winding pulling force and the lateral centrifugal force, thereby disrupting the balance of the two defect stresses, thereby avoiding the stacking of the two defect stresses, and improving the stability and safety of the winding process.

[0004] In the above-mentioned prior art, when winding the yarn, when winding the heavy yarn, it is necessary to take down the rolled yarn after the winding is completed. Due to the heavy weight of the yarn, it is more laborious to take it down, and the machine needs to be stopped to take down the wound yarn, and then a new reel needs to be reinstalled for a new round of winding, so the work efficiency is low.

DETAILED DESCRIPTION

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0039] Embodiment 1

[0041] The yarn is then wound around the outer edge of the drum 12 and the yarn is then cut off and the end of the yarn is fixed to the outer edge of the drum 12 at the upper end. The arc block 23 is then driven to slide toward the sides of the first cylindrical rod 11 located at the lower end, so that the arc block 23 is close to the sides of the first cylindrical rod 11, and then the arc block 23 is driven to slide toward the side of the first cylindrical rod 11 away from the first rectangular plate 13, and the reel 12 is pushed toward the side away from the first rectangular plate 13 until the reel 12 with the yarn wrapped thereon is completely removed, and the yarn is wound by driving the reel 12 at the upper end to rotate. After the winding is completed, the two reels 12 are exchanged when the circular plate 1 is driven to rotate, so that the wound reel 12 rotates to the lower end, and the new reel 12 rotates to the upper end, and then the yarn is cut off, and then a new round of winding work can be carried out, and the reel 12 with the yarn wrapped thereon is removed while the other reel 12 is continuously wound, and the reel 12 with the yarn wrapped thereon can be automatically removed, and the yarn winding can be realized without stopping the machine, thereby improving the work efficiency.

[0042] like Figure 4 As shown, the material picking assembly also includes a first L-shaped bar 231 fixedly connected to one side of the arc block 23, the lower end of the first L-shaped bar 231 is slidably connected to a rectangular tube 232, the lower ends of the two rectangular tubes 232 are slidably provided with a second slide rail 233, the lower ends of the rectangular tubes 232 are slidably provided with a third slide rail 234, and the third slide rail 234 is fixedly connected to the upper end of the second rectangular plate 2.

[0043] Specifically, after the reel 12 rotates to the lower end after winding is completed, the first L-shaped bar 231 is driven to drive the arc block 23 to slide upward until the arc block 23 slides to both sides of the first cylindrical rod 11, and then the rectangular tube 232 is driven to drive the arc blocks 23 on both sides to approach the first cylindrical rod 11 at the same time through the first L-shaped bar 231, until they are tightly attached to both sides of the first cylindrical rod 11, and then the second slide rail 233 is driven to move at the upper end of the third slide rail 234 away from the first rectangular plate 13. The second slide rail 233 drives the arc block 23 through the rectangular tube 232 to push the reel 12 away from the first rectangular plate 13 until the reel 12 is completely separated from the outside of the first cylindrical rod 11, and the reel 12 wrapped with yarn can be removed.

[0044] like Figure 5 As shown, a material receiving assembly is provided on the side of the second rectangular plate 2 away from the circular plate 1, and the material receiving assembly includes a second arc plate 5 provided on one side of the second rectangular plate 2, the second arc plate 5 is fixedly connected to a third arc plate 52 through a fifth spring 51, the second arc plate 5 can slide on the upper end of the third arc plate 52, the lower end of the third arc plate 52 is fixedly connected to a first rectangular block 53, and the lower end of the first rectangular block 53 is slidably provided with a fourth slide rail 54.

[0045] Specifically, when the driving arc block 23 pushes the reel 12 to the side away from the first rectangular plate 13, the reel 12 wrapped with yarn contacts the upper end of the second arc plate 5 during the pushing process, and the second arc plate 5 supports the reel 12. Then, the pushing continues, and the second arc plate 5 slides on the upper end of the third arc plate 52 and squeezes the fifth spring 51 until the reel 12 is completely pushed to the upper end of the third arc plate 52. The third arc plate 52 can support the reel 12 to prevent it from falling.

[0046] like Figure 5 As shown, a feeding assembly is provided on one side of the material receiving assembly, and the feeding assembly includes an arc base 6 provided on one side of the second arc plate 5, a third rectangular plate 61 is slidably provided on the lower end of the arc base 6, a second rectangular block 62 is fixedly connected to the lower end of the third rectangular plate 61, and a fifth slide rail 63 is slidably provided on the lower end of the second rectangular block 62.

[0047] Specifically, after removing the reel 12 wrapped with yarn, a new reel 12 is placed on the upper end of the arc base 6, and then the second rectangular block 62 is driven to drive the reel 12 placed on the upper end of the arc base 6 to slide toward the side close to the first cylindrical rod 11, and then the arc base 6 is driven to slide on the upper end of the third rectangular plate 61 toward the side close to the first cylindrical rod 11, so that the reel 12 can be automatically sleeved on the outside of the first cylindrical rod 11.

[0048] like Figure 7As shown, the middle part of the circular plate 1 is rotatably connected to the position of the first cylindrical rod 11, the second cylinder 14 is fixedly connected to the first cylindrical rod 11, and a plurality of first rectangular bars 112 are slidably passed through the first cylindrical rod 11 around. The middle part of the second cylinder 14 is fixedly connected to the second cylindrical rod 114 through a second spring 141, and the second cylindrical rod 114 can slide inside the second cylinder 14. The first rectangular bar 112 is rotatably connected to the second cylindrical rod 114 through a connecting rod 113, and a first cylinder 131 is rotatably provided on one side of the first rectangular plate 13 corresponding to the position of the first cylindrical rod 11 located at the upper end. A round head block 133 is fixedly connected to the inside of the first cylinder 131 through a first spring 132, and the round head block 133 can slide inside the second cylinder 14.

[0049] Specifically, after the reel 12 is sleeved on the outside of the first cylindrical rod 11, the second spring 141 pushes the second cylindrical rod 114 to the side away from the first rectangular plate 13, and the second cylindrical rod 114 pushes the first rectangular strip 112 to the outside of the first cylindrical rod 11 through the connecting rod 113, so that the first rectangular strip 112 is against the inner wall of the reel 12. When the driving reel 12 is located at the upper end, the second cylinder 14 located at the upper end is located on the side of the first cylinder 131. At this time, the first spring 132 pushes the round head block 133 to slide inside the second cylinder 14, so that the round head block 133 pushes the second cylindrical rod 114 to one side, so that the first rectangular strip 112 is closer to the inner wall of the reel 12, so that the reel 12 is fixed more firmly, preventing the reel 12 from falling off during rotation and winding.

[0050] like Figure 7 As shown, a cylindrical block 111 is fixedly connected to the side of the first cylindrical rod 11 away from the circular plate 1, and conical grooves 1111 are respectively arranged around the cylindrical block 111. A first slide rail 21 is fixedly connected to the upper end of the second rectangular plate 2. An arcuate bar 15 is arranged at the end of the first cylindrical rod 11 away from the circular plate 1. The arcuate bar 15 is rotatably connected to a first circular ring 151 on the side close to the first cylindrical rod 11. The arcuate bar 15 can slide on the upper end of the first slide rail 21. A conical block 153 is fixedly connected to the inside of the first circular ring 151 through a third spring 152, and the conical block 153 can slide in the conical groove 1111.

[0051] Specifically, when the first cylindrical rod 11 is driven to drive the reel 12 to rotate, the arc bar 15 is driven to drive the first ring 151 to move toward the side close to the cylindrical block 111 until the first ring 151 is sleeved on the outside of the cylindrical block 111, and the conical block 153 is inserted into the conical groove 1111 under the action of the third spring 152, ensuring that the reel 12 remains stable during rotation, further enhancing the fixing effect of the reel 12.

[0052] like Figure 6As shown, a rectangular frame 3 is fixedly connected to one side of the upper end of the first rectangular plate 13, and two arc-shaped rotating wheels 31 are rotatably provided in the middle of the upper end of the rectangular frame 3. The two arc-shaped rotating wheels 31 can slide on the upper end of the rectangular frame 3 through the second L-shaped bar 311. The second L-shaped bar 311 on one side is commonly fixed with a U-shaped block 32, and a second rectangular bar 321 is rotatably connected to one side of the U-shaped block 32, and two arc-shaped rotating wheels 31 are rotatably provided on the upper end of the second rectangular bar 321.

[0053] Specifically, when winding the yarn, the yarn end is passed between the two arc-shaped wheels 31 at the upper end of the second rectangular strip 321, and then the yarn end is placed between the two arc-shaped wheels 31 at the end of the second L-shaped strip 311, and then the yarn is passed through the rectangular frame 3 and fixed to the outside of the upper reel 12. While driving the reel 12 to rotate, the second L-shaped strip 311 is driven to drive the U-shaped block 32 and the second rectangular strip 321 to move synchronously, ensuring that the yarn is evenly wound on the reel 12, avoiding looseness or misalignment during the winding process, and improving the tightness and stability of the yarn winding. When the yarn becomes loose, the second rectangular strip 321 is driven to drive the two arc-shaped wheels 31 to rotate upward, lift the middle part of the yarn upward, so that the yarn is always in a taut state, realizing efficient automation of the yarn winding process, and significantly improving the quality and production efficiency of the yarn roll.

[0054] like Figure 8-Figure 9 As shown, a pressing assembly is respectively provided on one side of the rectangular frame 3 and one side of the upper end of the second rectangular plate 2, and the two pressing assemblies are respectively located on both sides, and the pressing assembly includes a first arc-shaped plate 4 respectively provided on one side of the first cylindrical rod 11, and a third rectangular bar 43 is fixedly connected to one side of the first arc-shaped plate 4, and the third rectangular bar 43 is rotatably connected to the rectangular frame 3 and one side of the second rectangular plate 2 through a fourth rectangular bar 44, and the first arc-shaped plate 4 is respectively fixedly connected to fan-shaped blocks 45 at both ends of the side close to the first cylindrical rod 11, and a plurality of fifth rectangular bars 452 are respectively fixedly connected inside the fan-shaped blocks 45 through fourth springs 451, and a cylindrical bar 453 is rotatably arranged between the two opposite fifth rectangular bars 452, and the first arc-shaped plate 4 on the upper end is fixedly connected to the cutting knife 41, and the first arc-shaped plate 4 on the lower end is fixedly connected to the knife seat 42.

[0055] Specifically, when there is a lot of yarn wrapped around the outside of the upper reel 12, the circular plate 1 is driven to rotate and drive the upper reel 12 to rotate to the lower end. At this time, the yarn needs to be pressed, and the third rectangular bar 43 is driven to rotate at one end of the fourth rectangular bar 44, driving the first arc plate 4 to rotate to the side of the first cylindrical rod 11. The first arc plate 4 drives the fan-shaped block 45 and the fifth rectangular bar 452 to rotate synchronously, so that the cylindrical bar 453 presses the yarn tightly to ensure that the yarn fits tightly to the reel 12, so that the yarn is close to the outside of the upper reel 12. After the yarn is cut off, a new round of yarn winding can be carried out. When the two first arc plates 4 are driven to rotate to the side of the first cylindrical rod 11, the cylindrical bar 453 is driven to squeeze the yarn on the outside of the reel 12, and at the same time, the cutting knife 41 contacts the knife seat 42 to cut the yarn.

[0060] Step 3, reel replacement: driving the circular plate 1 to rotate the reel 12 wound with yarn to the lower end, and rotating the other reel 12 not wound with yarn to the upper end, so that the position of the reel 12 is replaced;

[0061] Step 4: Processing the yarn ends: The first arc-shaped plates 4 on both sides drive the cylindrical strips 453 to rotate to one side of the first cylindrical rod 11, and the cylindrical strips 453 at the upper end press the yarn against the outside of the reel 12 that is not wound with the yarn, and the cylindrical strips 453 at the lower end press the yarn against the outside of the reel 12 that is wound with the yarn to prevent the yarn from loosening;

[0062] Step 5, cutting the yarn: In step 4, the first curved plate 4 drives the cylindrical strip 453 to squeeze the yarn outside the two reels 12 respectively, while the first curved plate 4 drives the cutting knife 41 to contact the knife seat 42 to cut the yarn between the two reels 12;

[0063] Step 6, taking out the rolled yarn: drive the two arc blocks 23 to approach each other, close to the two sides of the first cylindrical rod 11 at the lower end, and then drive the arc block 23 to slide to the side away from the first rectangular plate 13, and push the reel 12 at the lower end to the side away from the first rectangular plate 13, so that the reel 12 with the yarn wound at the lower end can be completely removed from the outside of the first cylindrical rod 11 and pushed to the upper end of the second arc plate 5; then place the new reel 12 on the upper end of the arc base 6, drive the arc base 6 to drive the reel 12 to move to one end of the first cylindrical bar 11 at the lower end, and then drive the arc base 6 to slide on the upper end of the third rectangular plate 61, so that the new reel 12 can be sleeved on the outside of the first cylindrical rod 11;

[0064] Step 7: Repeat steps 1 to 6 to continuously and automatically wind the yarn.

[0065] The cutting knife 41 used in step 5 may be a hard alloy fiber cutting knife.

[0066] Working principle: After the reel 12 is sleeved on the outside of the first cylindrical rod 11, the second spring 141 pushes the second cylindrical rod 114 to the side away from the first rectangular plate 13, and the second cylindrical rod 114 pushes the first rectangular strip 112 to the outside of the first cylindrical rod 11 through the connecting rod 113, so that the first rectangular strip 112 is against the inner wall of the reel 12. When the driving reel 12 is located at the upper end, the second cylinder 14 located at the upper end is located on the side of the first cylinder 131. At this time, the first spring 132 pushes the round head block 133 to slide inside the second cylinder 14, so that the round head block 133 pushes the second cylindrical rod 114 to one side, so that the first rectangular strip 112 is more closely attached to the inner wall of the reel 12, so that the reel 12 is fixed more firmly.

[0067] The yarn end is passed between the two arc-shaped wheels 31 at the upper end of the second rectangular strip 321, and then the yarn end is placed between the two arc-shaped wheels 31 at the end of the second L-shaped strip 311, and then the yarn is passed through the rectangular frame 3 and fixed to the outside of the winding drum 12 above, and then the arc strip 15 is driven to drive the first ring 151 to move toward the side close to the cylindrical block 111, until the first ring 151 is sleeved on the outside of the cylindrical block 111, and the conical block 153 is inserted into the conical groove 1111 under the action of the third spring 152. The second L-shaped strip 311 is driven to drive the U-shaped block 32 and the second rectangular strip 321 to move synchronously while driving the reel 12 to rotate, so as to ensure that the yarn is evenly wound on the reel 12, and to avoid looseness or misalignment during the winding process, thereby improving the tightness and stability of the yarn winding. When the yarn becomes loose, the second rectangular strip 321 is driven to drive the two arc-shaped wheels 31 to rotate upward, and the middle part of the yarn is lifted upward, so that the yarn is always in a taut state;

[0068] When the winding reaches a certain thickness, the circular plate 1 is driven to rotate so that the reel 12 wrapped with the yarn is located at the lower end, and the reel 12 without the yarn is located at the upper end, and the yarn end is fixed again on the outside of the reel 12 at the upper end, and then the winding can be carried out again, and at the same time, the arc block 23 is driven to slide to the two sides of the first cylindrical rod 11 at the lower end, so that the arc block 23 is close to the two sides of the first cylindrical rod 11, and then the arc block 23 is driven to slide on the outside of the first cylindrical rod 11 to the side away from the first rectangular plate 13, and the reel 12 is pushed to the side away from the first rectangular plate 13 until the reel 12 wrapped with the yarn is completely removed, and while the reel 12 wrapped with the yarn is removed, the other reel 12 is continuously reeled, and the reel 12 wrapped with the yarn can be automatically removed, and the yarn can be wound without stopping, thereby improving work efficiency.
