[0036] The application discloses a warp yarn tension guide frame.
[0037] Embodiment 1
[0038] Reference Figure 1 , 2 The warp yarn tension guide frame comprises a base frame 1, a yarn collecting frame 2, a yarn inlet roller 3, a tension roller 4 and a yarn outlet roller 5 mounted on the base frame 1. The yarn collecting frame 2, the yarn inlet roller 3, the tension roller 4 and the yarn outlet roller 5 are sequentially arranged from left to right, the yarn collecting frame 2 is provided with a plurality of yarn inlets 24 for guiding the warp yarn 100, and the yarn inlet roller 3, the tension roller 4 and the yarn outlet roller 5 are all rotationally mounted on the base frame 1.
[0039] When the warp yarn 100 is unwound, the warp yarn 100 is first gathered and combed through the yarn inlets 24 on the yarn collecting frame 2, then sequentially guided and transported through the yarn inlet roller 3, the tension roller 4 and the yarn outlet roller 5, and then transported to the subsequent loom head position for subsequent weaving work. In this process, the yarn inlet roller 3, the tension roller 4 and the yarn outlet roller 5 can guide and tension the transported warp yarn 100, thereby improving the subsequent weaving quality.
[0040] Specifically, the yarn collecting frame 2 comprises a top sealing plate 21, a bottom sealing plate 22 and a plurality of partition columns 23 mounted between the top sealing plate 21 and the bottom sealing plate 22. The plurality of partition columns 23 are uniformly and spacedly arranged and vertically rotationally arranged, so that the adjacent two partition columns 23 form the yarn inlet 24 for guiding the warp yarn 100 to gather. At the same time, during the transportation of the warp yarn 100 along the yarn inlet 24, the warp yarn 100 can form rotational contact with the partition column 23 to reduce friction and wear.
[0041] Specifically, in the embodiment, the number of the tension roller 4 is one, and the base frame 1 is hinged with the tension arm 61 on both sides, and the two tension arms 61 are symmetrically arranged. The two ends of the tension roller 4 are respectively rotatably installed on the two tension arms 61 away from the hinged ends of the tension arms 61. Correspondingly, the base frame 1 is installed with the stroke-adjustable cylinder 62 on both sides, and the cylinder body of the stroke-adjustable cylinder 62 is hinged to the base frame 1, and the piston rod end of the stroke-adjustable cylinder 62 is hinged to the tension arm 61. In the actual working process, the worker can control the swing of the tension arm 61 through the stroke-adjustable cylinder 62 to control the tension arm 61 to swing, so as to adjust the conveying tension of the warp yarn 100 to adapt to the warp yarn 100 with different tension requirements.
[0042] In the embodiment, the base frame 1 is installed with two first guide rollers 11, and the two first guide rollers 11 are installed between the tension roller 4 and the delivery roller 5. In the conveying process of the warp yarn 100 from the tension roller 4 to the delivery roller 5, the first guide roller 11 can assist in guiding the warp yarn 100 to further improve the conveying stability of the warp yarn 100.
[0043] Specifically, in the embodiment, the delivery roller 5 is a rubber-coated roller. In the actual conveying process, the warp yarn 100 can form a more compact contact with the delivery roller 5, so that the warp yarn 100 can maintain a more stable conveying state.
[0044] In the embodiment, the base frame 1 is also installed with a second guide roller 12 and a delivery reed 13; wherein the second guide roller 12 is installed on the right side of the delivery roller 5, and the delivery reed 13 is installed on the right side of the second guide roller 12. In the actual working process, the warp yarn 100 output from the delivery roller 5 is guided along the second guide roller 12, and then arranged by the delivery reed 13 and output to the loom head position outward, so as to facilitate the subsequent manufacturing work.
[0045] The implementation principle of the embodiment 1 is that when the warp yarn 100 is unwound, the warp yarn 100 is first collected and combed through the yarn inlet 24 on the yarn collecting frame 2, and then guided and conveyed in sequence through the yarn inlet roller 3, the two first guide rollers 11, the tension roller 4, the delivery roller 5 and the second guide roller 12, and then arranged by the delivery reed 13 and output to the loom head position outward, so as to facilitate the subsequent manufacturing work. In this process, the yarn inlet roller 3, the tension roller 4 and the delivery roller 5 can guide and tension the conveyed warp yarn 100, which can improve the subsequent weaving quality.
[0046] At the same time, in the actual working process, the worker can control the swing of the tension arm 61 through the stroke-adjustable cylinder 62 to control the tension arm 61 to swing, so as to adjust the conveying tension of the warp yarn 100 to adapt to the warp yarn 100 with different tension requirements.
[0047] Example 2:
[0048] The difference between this embodiment and example 1 is that the structure of the tension roller 4 is different.
[0049] Referring to Figure 3 , 4 Specifically, in this embodiment, the number of the tension roller 4 is four. The four tension rollers 4 are arranged in a diamond shape, and the left and right two tension rollers 4 are arranged in the horizontal direction, and the upper and lower two tension rollers 4 are arranged in the vertical direction.
[0050] The base frame 1 is also rotatably provided with a yarn separating guide roller 14 and a yarn combining guide roller 15. The yarn separating guide roller 14 is installed between the tension roller 4 and the yarn feeding roller 3, and the number of the yarn separating guide roller 14 is two, and the two yarn separating guide rollers 14 are arranged in the vertical direction. The yarn combining guide roller 15 is installed between the tension roller 4 and the yarn discharging roller 5, and the number of the yarn combining guide roller 15 is two, and the two yarn combining guide rollers 15 are arranged in the vertical direction.
[0051] In the actual conveying process of the warp yarn 100, the warp yarn 100 is guided and conveyed through the yarn collecting frame 2, the yarn feeding roller 3, the yarn separating guide roller 14, the tension roller 4, the yarn combining guide roller 15 and the yarn discharging roller 5. At the same time, the warp yarn 100 is separated by one and staggered at the position of the yarn feeding roller 3 to form two layers of warp yarn 100, and the upper layer of warp yarn 100 is guided and conveyed through the upper yarn separating guide roller 14, the left tension roller 4, the upper tension roller 4 and the upper yarn combining guide roller 15. Similarly, the lower layer of warp yarn 100 is guided and conveyed through the lower yarn separating guide roller 14, the lower tension roller 4, the right tension roller 4 and the lower yarn combining guide roller 15, and then the two layers of warp yarn 100 are combined on the yarn discharging roller 5, and finally conveyed to the outside loom head direction through the second guide roller 12 and the yarn arranging reed 13. In this process, the warp yarn 100 is divided into two layers, which can effectively avoid the overlapping and mutual interference of adjacent warp yarns 100, ensure the smoothness of the warp yarn 100 feeding, and achieve the purpose of improving the quality of the warp yarn 100 fabric product.
[0052] Referring to Figure 5Specifically, the base frame 1 is provided with horizontal slide rails 71 and vertical slide rails 72 on both inner sides, the vertical slide rails 72 are centrally arranged relative to the horizontal slide rails 71, and the vertical slide rails 72 cut the horizontal slide rails 71 at the positions of the horizontal slide rails 71. The left and right two tension rollers 4 are installed on the horizontal slide rails 71, and the upper and lower two tension rollers 4 are installed on the vertical slide rails 72. Each tension roller 4 is rotatably installed at both ends with a mounting seat 73, and the mounting seat 73 is fixed with a sliding block that slides on the corresponding horizontal slide rail 71 or vertical slide rail 72, so that the left and right two tension rollers 4 can slide in the horizontal direction, and the upper and lower two tension rollers 4 can slide in the vertical direction. Adjacent two tension rollers 4 are connected by equal-length connecting rods 74, and the connecting rods 74 are hinged between both ends and the corresponding tension rollers 4, so that the four tension rollers 4 can be linked by the connecting rods 74. The base frame 1 is installed with a support seat 75 below the lower tension roller 4, and a damping spring 76 is installed between the support seat 75 and the lower tension roller 4 on the corresponding side.
[0053] During the warp yarn 100 conveying process, when there is a deviation between the unwinding speed of the warp yarn 100 and the winding speed of the loom head position, the tension of the warp yarn 100 is easily changed. At this time, the damping spring 76 is deformed by elasticity to control the lower tension roller 4 to adjust up and down, and the lower tension roller 4 controls the remaining three tension rollers 4 to synchronously link through the connecting rod 74, so as to adaptively loosen the excessively tight warp yarn 100 or adaptively tighten the excessively loose warp yarn 100, so as to ensure the stability of the warp yarn 100 conveying.
[0054] Specifically, in the embodiment, the base frame 1 is rotatably installed with a first horizontal linkage rod 77 near the position of the lower tension roller 4, and the first horizontal linkage rod 77 is installed with a transmission gear 78 at both ends. Correspondingly, the mounting seat 73 on the lower tension roller 4 is fixed with a vertically arranged transmission rack 79, and the transmission gear 78 is engaged with the transmission gear 78.
[0055] During the adaptive adjustment of the tension of the warp yarn 100, since both ends of the lower tension roller 4 are synchronously transmitted by the first horizontal linkage rod 77, the adjustment consistency of both ends of the tension roller 4 can be further improved, so that the tension roller 4 is not easy to be stuck during adjustment, and the smoothness of adjustment can be ensured.
[0056] Specifically, in the embodiment, the support seat 75 is slidingly installed on the vertical slide rail 72. The base frame 1 is provided with a ball screw pair 710 on each side near the support seat 75, and the screw of the ball screw pair 710 is vertically arranged and rotatably installed on the base frame 1, and the nut of the ball screw pair 710 is fixedly connected to the support seat 75. A second horizontal linkage rod 711 is rotatably installed on the base frame 1, and the second horizontal linkage rod 711 is in transmission with the screws of the two ball screw pairs 710 on both sides through the intermeshing transmission of the bevel gear pairs at both ends. A driving motor 712 is installed on one side of the base frame 1, and the driving motor 712 drives the screw of the ball screw pair 710 on the corresponding side to rotate through the speed reducer 713.
[0057] In actual work process, since warp yarns 100 made of different materials have different tension requirements. Therefore, during installation, workers can drive the screw of the ball screw pair 710 on the same side to rotate through the driving motor 712, and the screw of the ball screw pair 710 drives the two support seats 75 on both sides to adjust up and down through the second horizontal linkage shaft, thereby adjusting the initial positions of the four tension rollers 4 through the control of the tension rollers 4 below to provide the required conveying tension for the warp yarns 100.
[0058] In the embodiment, the counterweight seat 714 is fixedly installed on the mounting seat 73 of the tension roller 4 below, and the counterweight seat 714 is loaded with adjustable number of counterweight blocks 715. During installation, workers can adjust the counterweight of the tension roller 4 below by increasing / decreasing the number of counterweight blocks 715, thereby being able to preset the initial elasticity of the damping spring 76 to adapt to the changing tension requirements.
[0059] The implementation principle of the embodiment 2 is:
[0060] When the warp yarns 100 are unwound, the warp yarns 100 are first collected and carded through the yarn inlet 24 on the yarn collecting frame 2, and then guided and conveyed through the yarn inlet roller 3, the tension roller 4, the yarn outlet roller 5 and the second guide roller 12 in sequence, and then arranged through the yarn arranging reed 13 and then output to the loom head position for subsequent manufacturing work.
[0061] Meanwhile, in the actual conveying process of the warp yarn 100, the warp yarn 100 is separated by turns and in staggered positions at the position of the feed roller 3 to form two layers of the warp yarn 100, and the upper layer of the warp yarn 100 is guided and conveyed through the upper separating guide roller 14, the left tension roller 4, the upper tension roller 4 and the upper combining guide roller 15; similarly, the lower layer of the warp yarn 100 is guided and conveyed through the lower separating guide roller 14, the lower tension roller 4, the right tension roller 4 and the lower combining guide roller 15, and then the two layers of the warp yarn 100 are combined on the delivery roller 5, and finally conveyed to the outside loom head direction through the second guide roller 12 and the delivery reed 13. In this process, the warp yarn 100 is separated into two layers, which can effectively avoid the overlapping and mutual interference of the adjacent warp yarn 100, ensure the smoothness of the warp yarn 100 feeding, and achieve the purpose of improving the product quality of the warp yarn 100 fabric.
