Description

Technical Field

[0001] This utility model relates to the field of carpet weaving technology, and in particular to a constant tension structure for carpet weaving. Background Technology

[0002] Carpet looms are specialized textile machines invented in the 1870s. They form tufts or loops of pile on the carpet surface through processes such as pile insertion, weft insertion, and weft beat-up. Their core components include pile beams, pile insertion mechanisms, and double weft insertion mechanisms. They can produce carpets from 1.6 meters to 4 meters wide and integrate intelligent control systems to improve efficiency. Modern carpet looms also use double-layer rapier weaving technology to produce fabrics with a pile height of 50 mm to meet different production needs. In the actual working environment of carpet looms, yarn slack will seriously affect the conveying. The temperature and humidity of the workshop fluctuate greatly. After the yarn absorbs or loses moisture, it expands and contracts, and the tension changes accordingly. When multiple strands of yarn are conveyed at the same time, it is difficult to balance the tension of each strand. A change in tension in one place will break the overall constancy, resulting in inconsistent quality of the woven carpet. Therefore, this utility model proposes a constant tension structure for carpet looms to solve the above problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a constant tension structure for carpet looms, which solves the problem in the prior art where, during operation, the yarn of a carpet loom easily expands and contracts due to changes in temperature and humidity, resulting in uneven tension among multiple yarns, leading to slack, affecting conveying, and causing inconsistent carpet quality.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a constant tension structure for a carpet loom, comprising a base plate, a support rod, a top plate and a movable plate, wherein the support rod is fixedly connected to the left side of the base plate, the top plate is fixedly connected to the top of the support rod, the movable plate is slidably connected to the outside of the support rod, and a tensioning mechanism is provided on the top of the movable plate.

[0005] A further improvement is made in that: the tensioning mechanism includes an assembly plate, a rotating rod, a limiting frame, a rotating shaft, a tensioning claw, and a tension spring. Multiple assembly plates are fixedly connected at equal intervals to the top of the movable plate. A rotating rod is hinged to the left side of the assembly plate. A tensioning claw is fixedly connected to the right end of the rotating rod through a rotating shaft. A limiting frame is fixedly connected to the left side of the assembly plate. The limiting frame and the rotating rod are connected to each other through a tension spring.

[0006] A further improvement is that one end of the rotating rod extends through the interior of the limiting frame, and connecting bolts are symmetrically inserted on both sides of the limiting frame. The limiting frame is detachably connected to the assembly plate through the connecting bolts.

[0007] A further improvement is that the tensioning claw is designed with an arc-shaped structure, and multiple guide blocks are evenly distributed on the outer side of the tensioning claw, with guide holes inside the guide blocks.

[0008] A further improvement is that threaded rods are symmetrically fixedly connected to both sides of the movable plate, and multiple partition blocks and assembly plates are provided through the outer side of the threaded rods. A nut is threaded to one end of the threaded rod, and the two sides of the partition blocks are respectively attached to one side of the two assembly plates.

[0009] A further improvement is made in that: a lead screw is rotatably connected to the right side of the base plate, and a motor is fixedly installed on the right side of the top plate. The output end of the motor is fixedly connected to the top end of the lead screw, and the bottom end of the lead screw passes through the right side of the movable plate and is threadedly connected to it.

[0010] A further improvement is that a protective shell is provided on the outside of the motor, and multiple anti-collision strips are fixedly connected at equal intervals on the outside of the protective shell. The anti-collision strips are rectangular in shape.

[0011] The beneficial effects of this utility model are as follows: the yarn passes through the guide holes and exits each guide block, and is connected to the tensioning claw as a whole. When the yarn vibrates, it drives the rotating rod and the tensioning claw to rotate simultaneously, thereby putting the tension spring in a stretched state. The elastic force generated by the tension spring drives the rotating rod and the tensioning claw to reset, and the yarn is re-tensioned. Moreover, the elastic force generated by the tension spring is constant, which makes the yarn conveying more stable. This solves the problem in the prior art that when the carpet loom is working, the yarn is prone to stretching and contracting due to changes in temperature and humidity, resulting in uneven tension of multiple yarns, which leads to slack, affects the conveying, and causes inconsistent carpet quality.

Detailed Implementation

[0014] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0015] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a constant tension structure for a carpet loom, including a base plate 1, a support rod 2, a top plate 3, and a movable plate 4. The support rod 2 is fixedly connected to the left side of the base plate 1, and the top plate 3 is fixedly connected to the top of the support rod 2. The movable plate 4 is slidably connected to the outside of the support rod 2. The top of the movable plate 4 is provided with a tensioning mechanism. In use, multiple strands of yarn are passed through multiple tensioning mechanisms on the movable plate 4. The tensioning mechanism separates the multiple strands of yarn from each other, and the tensioning mechanism has the ability to elastically recover. When the yarn vibrates, the elastic force drives the yarn to reset and re-tension it, making the yarn transport smoother.

[0016] The tensioning mechanism includes an assembly plate 5, a rotating rod 6, a limiting frame 7, a rotating shaft 8, a tensioning claw 9, and a tension spring 10. Multiple assembly plates 5 are fixedly connected at equal intervals to the top of the movable plate 4. The rotating rod 6 is hinged to the left side of the assembly plate 5. The tensioning claw 9 is fixedly connected to the right end of the rotating rod 6 via the rotating shaft 8. The limiting frame 7 is fixedly connected to the left side of the assembly plate 5. The limiting frame 7 and the rotating rod 6 are interconnected via the tension spring 10. The tensioning claw 9 has an arc-shaped structure. Multiple guide blocks 11 are evenly distributed on the outer side of the tensioning claw 9. Guide holes 12 are provided inside the guide blocks 11. The yarn passes through the guide holes 12 and exits each guide block 11, connecting with the tensioning claw 9 as a whole. When the yarn vibrates, it drives the rotating rod 6 and the tensioning claw 9 to rotate simultaneously, causing the tension spring 10 to be in a telescopic state. The elastic force generated by the tension spring 10 drives the rotating rod 6 and the tensioning claw 9 to reset, re-tensioning the yarn. The elastic force generated by the tension spring 10 is constant, thus making the yarn delivery more stable.

[0017] One end of the rotating rod 6 passes through the interior of the limiting frame 7. Connecting bolts are symmetrically inserted on both sides of the limiting frame 7. The limiting frame 7 is detachably connected to the assembly plate 5 through the connecting bolts. The limiting frame 7 is fixed to the assembly plate 5 through the connecting bolts. The rotating rod 6 passes through the inside of the limiting frame 7. The limiting frame 7 can limit the rotation range of the rotating rod 6.

[0018] The movable plate 4 is symmetrically fixedly connected to threaded rods 13 on both sides. Multiple partition blocks 14 and assembly plates 5 are provided through the outer side of the threaded rods 13. A nut is threaded to one end of the threaded rod 13. The two sides of the partition blocks 14 are respectively attached to one side of the two assembly plates 5. Multiple assembly plates 5 and partition blocks 14 are inserted into the outer side of the threaded rod 13 in sequence. Then, the nut is tightened on one end of the threaded rod 13. The nut is used to clamp and lock the multiple assembly plates 5 and partition blocks 14 in position. The partition blocks 14 are used to separate the multiple assembly plates 5 at equal distances, that is, to separate the yarns on the assembly plates 5 at equal distances.

[0019] A lead screw 16 is rotatably connected to the right side of the base plate 1, and a motor 15 is fixedly installed on the right side of the top plate 3. The output end of the motor 15 is fixedly connected to the top end of the lead screw 16. The bottom end of the lead screw 16 passes through the right side of the movable plate 4 and is threadedly connected to it. The support rod 2 can restrict the movement trajectory of the movable plate 4. The lead screw 16 and the movable plate 4 are threadedly engaged. When the output end of the motor 15 drives the lead screw 16 to rotate forward and backward, it can drive the movable plate 4 to move up and down along the outer wall of the support rod 2, thereby driving the yarn to move up and down within a certain range and finely adjusting the position of the yarn.

[0020] The motor 15 is provided with a protective shell on its outer side. Multiple anti-collision strips are fixedly connected at equal intervals on the outer side of the protective shell. The anti-collision strips are rectangular in shape. The protective shell and the anti-collision strips enclose the motor 15, separating the motor 15 from external objects and preventing the motor 15 from directly contacting external objects, thus protecting the motor 15.

[0021] The carpet loom uses a constant tension structure. The yarn passes through the guide hole 12 and exits through each guide block 11, and is connected to the tensioning claw 9. When the yarn vibrates, it drives the rotating rod 6 and the tensioning claw 9 to rotate simultaneously, thereby putting the tension spring 10 in a telescopic state. The elastic force generated by the tension spring 10 drives the rotating rod 6 and the tensioning claw 9 to reset, and the yarn is re-tensioned. The elastic force generated by the tension spring 10 is constant, which makes the yarn feeding more stable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
