Description
Technical Field
[0001] This invention relates to the field of three-dimensional loom technology, specifically to an intelligent feeding and take-up device for three-dimensional looms. Background Technology
[0002] A three-dimensional loom is a textile machinery device used to weave three-dimensional fabrics. It is developed based on the principle of traditional looms. The three-dimensional loom is based on the improvement of the traditional two-dimensional weaving principle. By designing multiple sets of warp yarns, weft yarns and binding yarns, it realizes the interweaving of high-performance fibers between layers. Its core is to precisely control the movement of a large number of multi-layer yarns in space along three dimensions to form a fabric preform with a specific three-dimensional shape and overall fiber structure. The role of the take-up mechanism is to pull the woven fabric away from the weave, and the take-up amount is set according to the weft density of the fabric to make the weft density of the fabric uniform.
[0003] In the existing technology, the three-dimensional loom is rigidly fixed to the upper and lower support beams by the chain fixing block. If there is an installation error in the chain, or the straightness of the support beam itself is insufficient, it will cause the support beam to drive the clamped yarn to deviate from the preset trajectory. The yarn will detach from the guide ring or deviate, which can easily cause the yarn to tangle together. The yarn will break due to the large traction force, thus causing the yarn to detach from the guide ring. Summary of the Invention

[0019] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1:
[0020] Please see Figure 1 - Figure 8As shown, a three-dimensional loom intelligent feeding take-up device includes a take-up frame 1, a rotating shaft 2, and a sprocket assembly 3. Two rotating shafts 2 are respectively located at both ends of the take-up frame 1, and two sets of sprocket assemblies 3 are respectively located on both sides of the take-up frame 1. The ends of the two sets of sprocket assemblies 3 are sleeved on both ends of the rotating shafts 2. Each set of sprocket assemblies 3 consists of two sprockets and a chain. Rotation of the rotating shafts 2 drives the sprockets and chains to rotate, and the two sets of sprocket assemblies 3 also rotate around the rotating shafts 2. A lower support beam 4 and an upper support beam 5 are arranged between the two sets of sprocket assemblies 3, and the lower support beam 4 and the upper support beam 5 move synchronously. The two ends of the lower support beam 4 are respectively connected to the two sets of sprockets. The components 3 are connected together. The two ends of the lower support beam 4 are connected to the chain of the sprocket assembly 3 via pins. The rotation of the chain of the sprocket assembly 3 drives the lower support beam 4 to move. The lower support beam 4 and the upper support beam 5 move along the chain of the sprocket assembly 3. A guide anti-detachment component 6 is provided between the lower support beam 4 and the upper support beam 5. The guide anti-detachment component 6 includes a lower clamping block 61 and an upper clamping block 62. The lower clamping block 61 and the upper clamping block 62 are respectively provided on the opposite sides of the lower support beam 4 and the upper support beam 5. The lower clamping block 61 is installed on the lower support beam 4 with screws, and the upper clamping block 62 is installed on the upper support beam 5 with screws. The lower clamping block 61 and the upper clamping block 62 are arranged opposite to each other. To facilitate the installation of the locking blocks 64 inside the lower clamping block 61 and the upper clamping block 62, a row of locking blocks 64 is provided on the opposite sides of the lower clamping block 61 and the upper clamping block 62. Each locking block 64 has a first reserved groove 65 inside, and a deformable guide ring 66 is embedded in the first reserved groove 65. The guide ring 66 is installed inside the first reserved groove 65, and the yarn passes through a set of corresponding guide rings 66. The inner wall of the lower clamping block 61 and the interior of the upper clamping block 62 are provided with reserved holes 63 at the positions of each guide ring 66. The interior of the reserved hole 63 of the lower clamping block 61 is connected to the interior of the corresponding reserved hole 63 of the upper clamping block 62. The yarn is arranged in a Z-shape. The reserved holes 63 in the lower clamping block 61 and the upper clamping block 62 are used to guide the yarn. The guide ring 66 made of deformable material can be adapted to yarns of different diameters. The guide ring 66 made of deformable material prevents the yarn from being worn. The Z-shaped arrangement of the yarn helps to straighten the yarn. The yarn is arranged in a specific position by following the inside of the corresponding guide ring 66. The yarn will not be tangled together. The guide ring 66 restricts the yarn inside the guide ring 66 and guides the yarn through the inside of the guide ring 66. The inside of the guide ring 66 is adapted to yarns of different diameters. The yarn can be tightened by using the Z-shaped arrangement of the yarn.
[0021] Please see Figure 4 and Figure 5As shown, the lower clamping block 61 and the upper clamping block 62 each have mounting grooves on their opposite surfaces, and the engaging block 64 is installed inside the mounting groove. The engaging block 64 can be embedded in the mounting groove, so that the engaging block 64 is securely installed inside the lower clamping block 61 and the upper clamping block 62. Each engaging block 64 has a first reserved groove 65 inside. The cross-sectional shape of the first reserved groove 65 is adapted to the cross-sectional shape of the guide ring 66. The guide ring 66 is engaged inside the first reserved groove 65. The guide ring 66 is truncated cone-shaped. The guide ring 66 can be placed inside the first reserved groove 65, so that the guide ring 66 is inserted into the first reserved groove 65. The outer surface of the guide ring 66 is used to smoothly connect the yarn in a Z-shape. The truncated cone shape of the guide ring 66 can reduce the friction between the yarn and the edge.
[0022] Please see Figure 4 and Figure 5 As shown, each guide ring 66 has a reserved opening 68 inside. The reserved opening 68 is used to put the yarn into the inside of the guide ring 66. One end of the guide ring 66 is integrally provided with a limit buckle 69, and the limit buckle 69 at one end of the guide ring 66 is connected to the other end of the guide ring 66. The limit buckle 69 is used to prevent the yarn from coming out of the inside of the guide ring 66. The yarn can enter the inside of the guide ring 66 through the reserved opening 68, and the reserved opening 68 of the guide ring 66 is closed by the limit buckle 69 to prevent the yarn from coming out of the reserved opening 68.
[0023] Please see Figure 3 and Figure 4 As shown, the first reserved groove 65 of the locking block 64 is provided with a first telescopic spring 67 on both sides. The ends of the two first telescopic springs 67 are in contact with the guide ring 66. The guide ring 66 is made of rubber. The first telescopic springs 67 are used to close the two ends of the guide ring 66. Since the guide ring 66 is made of deformable rubber, the shape of the guide ring 66 changes. Under the action of the first telescopic springs 67, the reserved opening 68 of the guide ring 66 becomes smaller, ensuring that the opening of the reserved opening 68 is relatively small, and preventing the yarn from detaching from the reserved opening 68 of the guide ring 66. The two ends of the guide ring 66 can be brought closer to each other by the first telescopic springs 67. The inside of the guide ring 66 is suitable for binding yarns of different diameters.
[0024] Please see Figure 6 - Figure 8As shown, a fixing post 610 is installed between the lower clamping block 61 and the upper clamping block 62, and at each reserved hole 63. The fixing post 610 is welded to the lower clamping block 61 and the upper clamping block 62. The fixing post 610 and the reserved holes 63 of each lower clamping block 61 and upper clamping block 62 are aligned. Each fixing post 610 has a reserved cavity 612 inside, and a mating hole 611 is opened on the inner end face of the reserved cavity 612. The positions of the mating hole 611, the reserved cavity 612 and the reserved hole 63 are corresponding. The yarn can pass through the interior of the mating hole 611 and the interior of the reserved cavity 612. A locking sleeve 613 and a second telescopic spring 615 are installed inside the reserved cavity 612. Under the action of the second telescopic spring 615, the locking sleeve 613 moves along the interior of the mating hole 611. The locking sleeve 613 moves, thereby changing the overlap between the locking sleeve 613 and the mating hole 611. The side wall of the locking sleeve 613 has a tension groove 614 for changing the diameter of the locking sleeve 613. Three clamping blocks 616 are installed inside the locking sleeve 613. The three clamping blocks 616 close to each other are used to clamp the yarn inside the locking sleeve 613. The locking sleeve 613 blocks inside the mating hole 611, causing the tension groove 614 of the locking sleeve 613 to close. Thus, the three clamping blocks 616 of the tension groove 614 move closer to each other. The second telescopic spring 615 pushes the locking sleeve 613 to move inside the mating hole 611. The three clamping blocks 616 close to each other to clamp the yarn. After the yarn breaks, it can be clamped by the clamping blocks 616 to prevent the yarn from falling out of the guide ring 66 after breaking.
[0025] Please see Figure 7 and Figure 8As shown, the position of the mating hole 611 corresponds to the position of the reserved hole 63. The mating hole 611 is frustum-shaped, and the locking sleeve 613 is also frustum-shaped. The yarn enters from the large end face of the locking sleeve 613 and exits from the small end face. The direction of yarn feeding is opposite to the direction of the force of the second telescopic spring 615, so the yarn is not affected by the second telescopic spring 615. After the yarn breaks, the elastic force of the second telescopic spring 615 increases, allowing the second telescopic spring 615 to extend. The diameter of the large end face of the locking sleeve 613 is larger than the diameter of the large end face of the mating hole 611. The tension groove 614 is V-shaped. When the large end face of the locking sleeve 613 fits into the large end face of the mating hole 611, the diameter of the large end face of the locking sleeve 613 decreases. Under the action of the second telescopic spring 615, the locking sleeve 613 can be moved, and the locking sleeve 613 slides inside the mating hole 611. The large end face of the locking sleeve 613 is pressed against the large end face of the mating hole 611, thereby reducing the gap of the loosening groove 614 and the diameter of the large end face of the mating hole 611. The three clamping blocks 616 move closer to each other, clamping the yarn. After the yarn breaks, the clamping blocks 616 clamp the yarn under the action of the second telescopic spring 615. The second telescopic spring 615 is located inside the fixing post 610. One end of the second telescopic spring 615 abuts against the large end face of the locking sleeve 613. The locking sleeve 613 slides along the inside of the mating hole 611. The second telescopic spring 615 abuts against the large end face of the locking sleeve 613. The extension of the second telescopic spring 615 causes the locking sleeve 613 to slide along the inside of the mating hole 611. The direction of the yarn conveying force is opposite to the direction of the second telescopic spring 615. The locking sleeve 613 is affected by the direction of the conveying force and the direction of the second telescopic spring 615.
[0026] Please see Figure 2 , Figure 9 - Figure 11As shown, both ends of one of the rotating shafts 2 are equipped with chain pretensioning assemblies 7. The chain pretensioning assembly 7 includes two sets of sliding bars 79, which are installed on the side of the winding frame 1. A floating plate 71 is provided between the two sets of sliding bars 79. The floating plate 71 slides along the sliding bars 79, thereby changing the position of the floating plate 71. Both ends of the rotating shaft 2 are connected to the floating plates 71 on both sides of the winding frame 1. The floating plate 71 moves along the inside of the sliding bars 79, causing the floating plate 71 and the rotating shaft 2 to move synchronously. A second reserved groove 77 is opened inside the floating plate 71, and a rack 78 is welded inside the second reserved groove 77. A drive motor 75 is installed on the inner wall of the winding frame 1, and a straight tooth is installed at the end of the drive motor 75. The spur gear 76 is located inside the second reserved slot 77. The spur gear 76 meshes with the rack 78. The spur gear 76 and the rack 78 are used to pre-tighten the rotating shaft 2. The drive motor 75 starts and drives the spur gear 76 to rotate. The movement of the spur gear 76 relative to the second reserved slot 77 can drive the floating plate 71 to move. The change in the position of the rotating shaft 2 causes the chain of the sprocket assembly 3 to be tightened, so the sprocket assembly 3 can be pre-tightened. The position of the floating plate 71 and the rotating shaft 2 can be adjusted by the drive motor 75. The floating plate 71 and the rotating shaft 2 move synchronously along the direction of the chain, which can pre-tighten the chain of the sprocket assembly 3. The fixed bolt 73 is used to abut against the edge of the floating plate 71 to prevent the position of the floating plate 71 from changing.
[0027] Please see Figure 9 - Figure 11 As shown, both floating plates 71 have fitting holes 74 on their surfaces. The interiors of the two fitting holes 74 are rotatably connected to both ends of the rotating shaft 2. The floating plates 71 are slidably connected to the sliding strips 79. The two floating plates 71 located on both sides of the winding frame 1 move synchronously with both ends of the rotating shaft 2. The two ends of the rotating shaft 2 move synchronously with the floating plates 71. The position of the rotating shaft 2 changes through the relative movement of the spur gear 76 and the rack 78.
[0028] Please see Figure 10 and Figure 11 As shown, fixing blocks 72 are welded to both sides of the winding frame 1. Fixing bolts 73 are threaded inside the fixing blocks 72. Rotating the fixing bolts 73 causes them to engage with the fixing blocks 72. Adjusting the protrusion position of the fixing bolts 73 allows for the adjustment of the position of the bolts. Side plates are welded to the edge of the floating plate 71. The end of the fixing bolts 73 contacts the side plates. The fixing bolts 73 are used to restrict the movement of the floating plate 71 and the rotating shaft 2 towards the center of the winding frame 1. The thread length of the fixing bolts 73 is matched with the length of the rack 78. After adjusting the position of the rotating shaft 2 and the position of the floating plate 71, the fixing bolts 73 can be used to press against the floating plate 71 to prevent the floating plate 71 from moving and causing the position of the rotating shaft 2 to change.
