Description
Technical Field
[0001] This utility model relates to the field of loom accessories, and in particular to a fabric stabilization mechanism for a rapier loom. Background Technology
[0002] Rapier looms are an important type of shuttleless loom and are core equipment in the textile machinery field used for weaving various fabrics. They achieve precise introduction of weft yarn through a unique weft insertion mechanism (rapier head), and are characterized by strong adaptability, high weaving efficiency, and stable product quality.
[0003] During the weaving process on a rapier loom, the heald frames periodically rise and fall according to the fabric structure, separating the warp yarns into upper and lower layers to form a shed. Once the shed is formed, the rapier carries the weft yarn through the shed and interweaves with the upper and lower warp yarns. At this time, the warp yarns remain in a layered state under the action of the shedding mechanism until the weft yarn has completely passed through the shed.
[0004] Because rapier looms often require two sets of warp threads to move back and forth alternately in the up and down direction during the weaving process, the woven fabric is easily moved by the warp threads, resulting in unstable position and affecting the finished product. To address this issue, a fabric stabilization mechanism for rapier looms is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 , Figure 2 and Figure 4 One embodiment of this utility model is a fabric stabilization mechanism for a rapier loom, comprising a base plate 1, the upper surface of the base plate 1 being flat, and a woven fabric being placed on the upper surface of the base plate 1. Side plates 2 are fixedly connected to the upper surface of the base plate 1 near the front and rear ends. The number of side plates 2 is set to two, and the distance between the two side plates 2 is greater than the width of the fabric, i.e., the length of the weft thread.
[0037] Reference Figure 1 , Figure 2 and Figure 5A stabilizing component 3 is provided on the inner side of the side plate 2 and the upper end of the bottom plate 1. The stabilizing component 3 includes a sliding groove 31, which is located at one end of the side plate 2 near the middle of the bottom plate 1. A sliding plate 32 is slidably connected to the inner wall of the sliding groove 31. The sliding plate 32 slides up and down. A sleeve 33 is fixedly connected to the bottom end of the sliding plate 32. The sleeve 33 is hollow with an opening at the bottom. A sliding piece 34 is slidably connected to the inner wall of the sleeve 33. The sliding piece 34 slides up and down relative to the sleeve 33. A connecting block 35 is fixedly connected to the bottom end of the sliding piece 34. A rotating shaft 36 is fixedly connected to one end of the connecting block 35 near the middle of the bottom plate 1. A pressure roller 37 is rotatably connected to the outer wall of the rotating shaft 36. The pressure roller 37 is used to press the upper end of the fabric. Through the cooperation of the pressure roller 37 and the bottom plate 1, the fabric can be pressed firmly. The fabric surface is well fixed to achieve a stable effect. The number of rotating shafts 36 and pressure rollers 37 is set to two, and the two pressure rollers 37 are respectively set at the upper end of the bottom plate 1 near the left and right sides. By setting the number of pressure rollers 37, it is ensured that both ends of the fabric surface can be fixed, thereby ensuring the stability of the fabric surface. The upper surface of the sliding plate 34 is elastically connected to the inner wall of the sleeve 33 by a spring 38. One end of the spring 38 is fixedly connected to the upper surface of the sliding plate 34, and the other end of the spring 38 is fixedly connected to the inner wall of the sleeve 33. The top of the sliding plate 32 is rotatably connected to a threaded rod 39. The outer wall of the threaded rod 39 passes through and is threadedly connected to the inner wall of the side plate 2. The front end of the bottom plate 1 is fixedly connected to a support plate 4. The upper surface of the support plate 4 is fixedly connected to a motor 5. The output shaft of the motor 5 is fixedly connected to a clamp 7.
[0038] Reference Figure 2 , Figure 3 and Figure 6 A winding mechanism 6 is provided at the left end of the base plate 1. The winding mechanism 6 includes a winding wheel 61. The outer wall of the winding wheel 61 has a fabric clamping opening 62. The left end of the warp thread is located inside the fabric clamping opening 62. The inner wall of the winding wheel 61 has a pressure chamber 63. The pressure chamber 63 is approximately crescent-shaped and does not pass through the midpoint of the winding wheel 61. The inner wall of the pressure chamber 63 is piston-connected to a sliding plate 64. The shape of the sliding plate 64 matches the shape of the pressure chamber 63. The inner wall of the winding wheel 61 has an arc-shaped chamber 65. The arc-shaped chamber 65 is arc-shaped. The inner wall of the arc-shaped chamber 65 is piston-connected to a clamping block 66. The outer wall of the clamping block 66 fits against the inner wall of the arc-shaped chamber 65, and the clamping block 66 can move along the arc surface of the arc-shaped chamber 65. The arc-shaped chamber 65 is connected to the interior of the pressure chamber 63. When the internal pressure of the pressure chamber 63 increases, the gas inside it can enter the arc-shaped chamber 65.
[0039] Reference Figure 6 , Figure 7 and Figure 9A control component 67 is provided on the outside of the sliding plate 64 and inside the winding wheel 61. The control component 67 includes a screw 671, the outer wall of which penetrates and is threadedly connected to the inner wall of the winding wheel 61. The front end of the screw 671 is rotatably connected to the rear end of the sliding plate 64. This rotatable connection ensures that the screw 671 can rotate relative to the sliding plate 64, thus ensuring that the sliding plate 64 does not rotate with the screw 671. A control groove 672 is formed on the inner wall of the screw 671, and a slider 673 is slidably connected to the inner wall of the control groove 672. The shape of the slider 673 is similar to that of the control groove 671. The shape of 72 fits, and the shape of the control groove 672 is a cylinder with a non-circular cross-section. The rear end of the slider 673 is fixedly connected to the rotating rod 674, and the rear end of the rotating rod 674 is fixedly connected to the control plate 675. The control plate 675 is cylindrical, and the outer wall of the control plate 675 is rotatably connected to the inner wall of the take-up wheel 61. The rear surface of the control plate 675 is on the same plane as the rear surface of the take-up wheel 61. The control port 676 is cross-shaped. The cross-shaped control port 676 ensures that the operator can better rotate the control plate 675. The control port 676 is opened at the rear end of the control plate 675.
[0040] Reference Figures 6-8 The winding reel 61 has a fixing component 68 inside, which includes a drive rod 681. The drive rod 681 is cylindrical and has a groove 682 on its inner wall. A sliding block 683 is slidably connected to the inner wall of the groove 682. The outer wall of the sliding block 683 is elastically connected to the inner wall of the groove 682 by a spring 684. One end of the spring 684 is fixedly connected to the outer wall of the sliding block 683, and the other end of the spring 684 is fixedly connected to the inner wall of the groove 682. The clamp 7 is set on the outer side of the side plate 2. The front and rear ends of the sliding block 683 away from the drive rod 681 are provided with inclined chamfers. By setting the inclined chamfers, it is ensured that when the sliding block 683 moves back and forth, it can move into the groove 682 by contacting other objects through the chamfers. The inner wall of the winding reel 61 has a slot 685, and the front end of the drive rod 681 is set inside the clamp 7.
[0041] Working principle: When in use, the operator first installs the take-up reel 61 at the left opening of the base plate 1 and ensures that the control plate 675 is in a position close to the left.
[0042] After the take-up reel 61 is placed, the worker inserts the drive rod 681 into the opening at the left end of the base plate 1 and the inside of the take-up reel 61, and fixes the front end of the drive rod 681 with the clamp 7.
[0043] Since the sliding block 683 has chamfered edges on both the front and rear outer sides, when the drive rod 681 slides into the winding wheel 61, the chamfered edge at its front end is subjected to force, which allows it to enter the interior of the slide groove 682. Therefore, the sliding block 683 will not affect the installation of the drive rod 681.
[0044] After installation, the worker inserts the left end of the warp into the fabric clamping opening 62, and then drives the control plate 675 to rotate through the control port 676, which in turn drives the rotating rod 674 to rotate synchronously, thereby causing the slider 673 to rotate.
[0045] When the slider 673 rotates, the outer wall of the slider 673 pushes the inner wall of the control groove 672, thereby causing the screw 671 to rotate. Since the screw 671 is threadedly connected to the winding wheel 61, it moves towards the middle of the pressure chamber 63 while rotating due to the shape limitation of the threaded groove inside the winding wheel 61. During the movement, it pushes the sliding plate 64, thereby pushing the gas inside the pressure chamber 63 into the arc-shaped chamber 65.
[0046] As the gas inside the arc-shaped chamber 65 increases, the clamping block 66 clamps the warp under the pushing force of the gas.
[0047] Therefore, during normal use of the equipment, the motor 5 drives the clamp 7 and the drive rod 681 to rotate, which in turn causes the take-up wheel 61 to rotate and the fabric to be wound up.
[0048] After the left end of the warp is fixed, the worker rotates the threaded rod 39, which causes the sliding plate 34 to move up and down during the rotation. The sliding plate 34 then causes the sleeve 33 to move up and down, which in turn causes the spring 38 and the connecting block 35 to move synchronously with it.
[0049] When the connecting block 35 moves up and down, it also drives the rotating shaft 36 and the pressure roller 37 to move up and down. When the bottom end of the pressure roller 37 contacts the upper surface of the fabric, the pressure roller 37 can no longer move downwards, so the connecting block 35 can no longer move downwards. If the operator continues to rotate the threaded rod 39, and the threaded rod 39 drives the slide plate 32 downwards during the rotation, the sleeve 33 moves synchronously with it. Since the connecting block 35 can no longer move downwards, the spring 38 is compressed. Therefore, the spring 38 has an elastic force in the reset direction and drives the connecting block 35 downwards. So, in addition to the force of direct contact with the fabric, the pressure roller 37 also has a downward pressure. And because the spring 38 has the ability to deform, during the movement of the fabric, whether the point of direct contact between the pressure roller 37 and the fabric is the location of the weft thread or the position between two weft threads, it can fit well with the bottom surface of the pressure roller 37, thus ensuring the stability of the fabric.
[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
