Description

Technical Field

[0001] The utility model relates to a beating-up device, in particular to a heddle beating-up device for 2.5D three-dimensional weaving of quartz yarns. Background Art

[0002] The 2.5D three-dimensional fabric of quartz yarns is woven by a weaving machine with quartz fibers. The weaving process of quartz fibers includes processes such as warp threading, weft insertion, and beating-up. During beating-up, the weft yarns need to be beaten by the beating-up mechanism of the weaving machine to tightly weave the weft yarns between the warp yarns. The patent application with the publication number CN220846469U discloses a six-link beating-up mechanism, which includes a crankshaft connecting rod, a bearing bush connecting rod, a triangular connecting rod, a small eight-shaped connecting rod, a rocker, a swinging shaft, and a reed. The lower end of the bearing bush connecting rod is rotatably connected to the connecting rod journal of the crankshaft connecting rod, and the upper end of the bearing bush connecting rod is rotatably connected to the lower corner end of the triangular connecting rod. The triangular connecting rod is installed on the frame through a central shaft. The upper corner end of the triangular connecting rod is rotatably connected to the small eight-shaped connecting rod, the upper end of the small eight-shaped connecting rod is rotatably connected to the lower end of the rocker, the upper end of the rocker is pivotally connected to the central rotating shaft of the swinging shaft, and the swing rod at the upper end of the swinging shaft is connected to install the reed. The overall structure of the utility model is simple, which significantly improves the beating-up force. Moreover, the reed has a long pause time after being placed at the rear, increasing the available weft insertion angle. The weft yarns pass through more smoothly and stably. It can not only weave low-gram-weight fabrics but also be applicable to the weaving of high-gram-weight fabrics. At the same time, it can also reduce the vibration and noise of the beating-up part of the loom.

[0003] During the beating-up process of the above-mentioned beating-up mechanism, the reed swings around the swinging shaft to beat the weft yarns. When the reed pushes the weft yarns between the warp yarns, there is also a downward pressing trend on the weft yarns. Under this downward pressing trend, the tension borne by the warp yarns above the weft yarns is greater than that borne by the warp yarns below the weft yarns, resulting in uneven stress on the warp yarns and causing the manufactured quartz fiber cloth to be uneven. Therefore, it is necessary to redesign a heddle beating-up device for 2.5D three-dimensional weaving of quartz yarns to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a heddle beating-up device for 2.5D three-dimensional weaving of quartz yarns, which can push the weft yarns horizontally, ensure that the warp yarns above the weft yarns and the warp yarns below the weft yarns are stressed uniformly, and guarantee uniform stress, aiming at the deficiencies of the prior art.

[0018] The heddle beating-up device for 2.5D three-dimensional braiding of quartz yarn is composed of a frame 1, a cloth winding mechanism and a beating-up mechanism. A cloth winding mechanism is arranged on the frame 1 to wind the woven quartz fiber cloth through the cloth winding mechanism, so as to avoid the accumulation of the quartz fiber cloth at the beating-up position and affect the beating-up. A beating-up mechanism is arranged on the frame 1 on one side of the cloth winding mechanism to beat the weft yarn through the beating-up mechanism, so that the weft yarn and the warp yarn are tightly woven.

[0019] The beating-up mechanism is composed of a servo motor 2, an eccentric wheel 3, a parallel frame, a fixed seat 4 and a beating-up reed 5. An eccentric wheel 3 is arranged on the output shaft of the servo motor 2. A parallel frame forming a parallelogram four-bar mechanism is arranged on one side of the eccentric wheel 3. A fixed seat 4 is arranged on the top of the parallel frame. The beating-up reeds 5 are evenly distributed on the top of the fixed seat 4. The beating-up reeds 5 are spaced from each other so that the warp yarn can pass through between the beating-up reeds 5, and the warp yarn is constrained by the beating-up reeds 5. The function of the servo motor 2 is to drive the eccentric wheel 3 to rotate through the servo motor 2. During the eccentric rotation of the eccentric wheel 3, the parallel frame is driven to move. Since the parallel frame is a parallelogram four-bar mechanism, the swing angle of the fixed seat 4 arranged on the top of the parallel frame remains unchanged during the swing of the parallel frame. Furthermore, the beating-up reed 5 only beats and pushes the weft yarn, and does not press down the weft yarn, so that the warp yarn above the weft yarn and the warp yarn below the weft yarn are subjected to the same force, thereby ensuring uniform weaving and ensuring the uniformity of the woven quartz fiber cloth.

[0020] The parallel frame is composed of a support shaft 6, a swing arm 7 and a support rod 8 arranged in parallel. The swing arm 7 is arranged on the support shaft 6, and the swing arms 7 are parallel to each other; a connecting rod 9 is arranged between the swing arm 7 and the eccentric wheel 3. One end of the connecting rod 9 is movably connected to the eccentric wheel 3 through a pin shaft, and the other end of the connecting rod 9 is movably connected to the swing arm 7 through a pin shaft; a support rod 8 is arranged between the swing arms 7 of different support shafts 6. The support rod 8 is movably connected to the swing arm 7 through a pin shaft; the support rod 8 is parallel to the horizontal plane where the support shaft 6 is located; the support shaft 6 is movably connected to the frame 1 through a bearing seat; the support rod 8 is fixedly connected to the fixed seat 4. The support shaft 6, the swing arm 7 and the support rod 8 form a parallelogram four-bar mechanism. Since the relative position of the support shaft 6 remains unchanged, the support rod 8 can always maintain a horizontal state during the swing, and further the fixed seat 4 always maintains a horizontal state. Thus, the angle of the beating-up reed 5 remains unchanged during the movement, ensuring that the beating-up reed 5 does not press down the weft yarn when beating the weft yarn, thereby ensuring balanced force.

[0021] The cloth winding mechanism consists of a cloth winding roller 10 and a cloth winding motor 11. The cloth winding motor 11 is arranged on one side of the cloth winding roller 10 and is connected to the cloth winding roller 10 through a synchronous pulley and a synchronous belt. The cloth winding roller 10 is movably connected to the frame 1 through a bearing seat. The cloth winding motor 11 can drive the cloth winding roller 10 to rotate through the synchronous pulley and the synchronous belt, so as to wind the finished quartz fiber cloth woven by the rotating cloth winding roller 10.

[0022] A cloth guiding roller 12 is movably installed on the frame 1 above the cloth winding roller 10 through a bearing seat to guide and reverse the quartz fiber cloth through the cloth guiding roller 12, avoid the collision between the quartz fiber cloth and the moving beating-up mechanism, and thus protect the quartz fiber cloth.

[0023] A cloth guiding rod 13 is arranged on the frame 1 between the cloth guiding roller 12 and the beating-up reed 5 to adjust the angles of the warp and weft at the beating-up position through the cloth guiding rod 13, so as to ensure the angle between the beating-up reed 5 and the weft. By adjusting the angles of the warp and weft, the acting forces of the beating-up reed 5 on the weft and warp are made uniform and consistent, thereby ensuring uniform weaving.

[0024] When the heddle frame beating-up device for 2.5D three-dimensional weaving of the quartz yarn works, weft insertion is carried out. After the weft insertion is completed, the servo motor 2 is started to make the servo motor 2 rotate one circle. During the rotation of the servo motor 2, the beating-up reed 5 is driven to beat the weft through the eccentric wheel 3, the parallel frame and the fixed seat 4 in sequence, so that the weft and the warp are tightly woven. After the beating-up is completed, the warp is reversed, the warp above the weft is reversed below the weft, and the warp below the weft is reversed above the weft. After the warp reversal is in place, the cloth winding motor 11 is started, and the cloth winding motor 11 drives the cloth winding roller 10 to rotate through the synchronous belt and the synchronous pulley in sequence to wind the quartz fiber cloth. After the quartz fiber cloth is wound in place, the above process is repeated to enter the next working cycle and continue to weave the quartz fiber cloth.

[0025] The parallel frame of the heddle frame beating-up device for 2.5D three-dimensional weaving of the quartz yarn forms a parallelogram four-bar mechanism, which can keep the angle of the beating-up reed 5 unchanged when driving the beating-up reed 5 to move. The beating-up reed 5 only pushes the weft forward without pressing down the weft, so that the warp is uniformly stressed, ensuring uniform weaving of the quartz fiber cloth and effectively improving the finished product quality. The moving parts of the parallel frame, the eccentric wheel 3 and the servo motor 2 are all arranged below the warp and the weft, and the moving parts are not easy to contact the warp and the weft, so it is not easy to affect the weaving. It solves the problem of uneven stress existing in the existing beating-up mechanism, which leads to uneven weaving.
