Description

Technical Field

[0001] This utility model belongs to the field of weaving equipment, specifically relating to a circular loom. Background Technology

[0002] A circular loom is an industrial device used to weave tubular fabric. The tubular fabric is woven by the cross-weft of warp and weft threads. The warp threads are threaded through the thread holes of the heddles. The reciprocating motion of the heddles drives the heddles and the warp threads threaded through the heddles to move up and down. The weft threads pass through the reciprocating warp threads to weave the tubular fabric.

[0003] Currently, circular looms typically use a planar cam to drive the end of a rocker arm to swing up and down, thereby moving the heald belt up and down. To connect the rocker arm, the heald belt assembly includes three heald belts, with a connector between two of them. The end of the rocker arm is rotatably connected to the connector. When the rocker arm swings, it rotates relative to the connector, causing the connector to move, which in turn moves the heald belt up and down. This structure is complex. Furthermore, because the rocker arm's trajectory is arc-shaped during its up-and-down swing, the connector, driven by the rocker arm, undergoes not only vertical displacement but also horizontal displacement. This causes the heald belt and heald wires to change position simultaneously in both the horizontal and vertical directions. The repeated horizontal displacement of the heald wires causes them to repeatedly wear down the warp threads threaded through the heald wire guide holes, easily damaging the warp threads and causing significant wear on the heald wires, thus shortening their lifespan. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a circular loom to solve the problem of wear on the warp yarns caused by repeated horizontal movement of the heddles when they drive the warp yarns to move up and down.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A circular loom includes a heald belt assembly and upper and lower rollers for tensioning the heald belt assembly, and also includes a linear drive mechanism with an output rod. The heald belt assembly includes two heald belts and two rows of parallel heald yarns. The two heald belts respectively cover the upper and lower rollers. The upper and lower ends of the two rows of heald yarns are respectively connected to the ends of the two heald belts to form an annular heald belt assembly. The heald belts have through holes, and the output rod passes through the through holes, causing the heald yarns to reciprocate up and down by pulling the heald belts up and down. This technical solution has the following technical effects:

[0006] This invention features a circular loom with a linear drive mechanism whose output rod is directly connected to the heald belt of the heald belt assembly. The linear drive mechanism converts rotational motion into linear motion of the heald belt in the vertical direction. This causes the heald threads connected to the heald belt to pull the warp threads threaded within them in a reciprocating vertical motion. Throughout the entire movement, the heald threads only shift vertically, pulling or pressing the warp threads upwards or downwards. This avoids excessive wear on the warp threads caused by repeated horizontal displacement of the heald threads, effectively protecting the warp threads and preventing the generation of excessive dust due to excessive warp wear. Furthermore, because the drive structure for the heald belt assembly is a linear drive mechanism, the output rod can be directly inserted into the heald belt for transmission. Each heald belt assembly only needs two heald belts to achieve the vertical movement of two rows of heald threads, simplifying the structure of the heald belt assembly and reducing the difficulty of its production and processing.

[0007] In the aforementioned circular loom, a mounting block is provided on the side of the heald belt facing the linear drive mechanism. The mounting block has mounting holes aligned with through holes. An output rod passes through the mounting holes and extends into the through holes to move in conjunction with the heald belt. The mounting holes on the mounting block increase the contact area between the output rod and the heald belt assembly, making it less likely to damage the heald belt when the output rod moves radially up and down to drive the heald belt up and down. Simultaneously, the mounting block fills the gap between the end face of the linear drive mechanism and the side face of the heald belt, preventing the heald belt from wobbling into the gap and making the up and down movement of the heald belt more stable.

[0008] In the aforementioned circular loom, the mounting block is equipped with locking elements located on both sides of the mounting hole. These locking elements are locked to the heald belt to fix the mounting block onto the heald belt. By locking the two locking elements to the heald belt, the mounting block is detachably connected to the heald belt, ensuring that the mounting hole and the through hole on the heald belt are always aligned. In the event of damage to the mounting block or the heald belt, both can be separated for individual replacement, reducing maintenance and replacement costs.

[0009] In the aforementioned circular loom, the locking element is a locking screw. The locking screw passes through the heald belt and locks itself to the mounting block, so that the head of the locking screw and the mounting block together clamp the heald belt. Using a locking screw as the locking element simplifies the structure of the locking element and facilitates its installation and disassembly.

[0010] In the aforementioned circular loom, the mounting block and the heald belt are non-detachably connected. This ensures that once connected, the mounting block and heald belt cannot be separated. By making this non-detachable connection, users can directly insert the output rod into the mounting hole and through hole without needing to assemble the mounting block and heald belt beforehand, reducing assembly steps and simplifying the assembly process.

[0011] In the aforementioned circular loom, a stop element is detachably connected to one end of the output rod that passes through the heald belt. This stop element abuts against the heald belt around the through hole to prevent the output rod from detaching from the through hole. By abutting against the heald belt on the outer periphery of the through hole, the stop element prevents the output rod from freely separating from the through hole, thus avoiding the inability to transmit power between them and ensuring stable transmission between the output rod and the heald belt. This, in turn, ensures that the heald belt drives the warp yarn to move stably up and down.

[0012] In the aforementioned circular loom, the anti-reverse component is an anti-reverse nut, which is threadedly connected to the output rod. By using an anti-reverse nut as the anti-reverse component, the installation and removal of the anti-reverse component and the output rod can be achieved simply by rotating the anti-reverse nut, making operation convenient and simple. Furthermore, the position of the anti-reverse component in the axial direction of the output rod can be adjusted by rotating the anti-reverse nut. Even if there are certain manufacturing errors in the length of the output rod, rotating the anti-reverse nut will ensure that it abuts against the heald belt, thereby guaranteeing the limiting effect of the anti-reverse component on the output rod.

[0013] In the aforementioned circular loom, the end of the output rod is provided with an annular groove, and the anti-reverse element is a retaining spring, with its inner ring engaging within the annular groove. By using a retaining spring as the anti-reverse element to engage with the annular groove on the output rod, relative rotation between the anti-reverse element and the output rod is possible. Even if the output rod rotates slightly due to friction between itself and the connecting parts, or if the retaining spring rotates due to vibration, the anti-reverse element will not move axially on the output rod, ensuring that the anti-reverse element remains stably abutted against the heald belt.

[0014] In the aforementioned circular loom, the linear drive mechanism further includes planetary gears, an input shaft, and a connecting member. The input shaft is connected to the planetary gears to drive them to revolve around the input shaft and rotate on their own axis. One end of the connecting member is rotatably connected to the central shaft of the planetary gears, and the other end is provided with an output rod passing through a through hole. The structure is simple, and the transmission is stable and reliable.

[0015] In the aforementioned circular loom, the loom includes a frame with an upper mounting base and a lower mounting base. The upper mounting base has an upwardly inclined upper slot, into which the end of an upper roller engages. The lower mounting base has a downwardly inclined lower slot, into which the end of a lower roller engages. This design facilitates the installation of the upper and lower rollers while allowing for a certain amount of movement for both rollers on the upper and lower mounting bases. This allows for adjustment of the tension of the heald belt assembly, preventing over-tensioning and ensuring that the heald belt assembly maintains a suitable tension. This protects the heald belt assembly while facilitating transmission.

[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0028] This utility model proposes a circular loom, including a heald belt assembly and upper and lower rollers for tensioning the heald belt assembly, as well as a linear drive mechanism with an output rod. The heald belt assembly includes two heald belts and two rows of parallel healds. The two heald belts are respectively wrapped around the upper and lower rollers. The upper and lower ends of the two rows of healds are respectively connected to the ends of the two heald belts to form an annular heald belt assembly. The heald belts are provided with through holes, and the output rod passes through the through holes. By pulling the heald belts up and down, the healds are made to reciprocate up and down. This invention features a circular loom with a linear drive mechanism whose output rod is directly connected to the heald belt of the heald belt assembly. The linear drive mechanism converts rotational motion into linear motion of the heald belt in the vertical direction. This causes the heald threads connected to the heald belt to pull the warp threads threaded within them in a reciprocating vertical motion. Throughout the entire movement, the heald threads only shift vertically, pulling or pressing the warp threads upwards or downwards. This avoids excessive wear on the warp threads caused by repeated horizontal displacement of the heald threads, effectively protecting the warp threads and preventing the generation of excessive dust due to excessive warp wear. Furthermore, because the drive structure for the heald belt assembly is a linear drive mechanism, the output rod can be directly inserted into the heald belt for transmission. Each heald belt assembly only needs two heald belts to achieve the vertical movement of two rows of heald threads, simplifying the structure of the heald belt assembly and reducing the difficulty of its production and processing.

[0034] Example 1:

[0035] A circular loom, such as Figures 1 to 5As shown, it includes multiple sets of drive devices for moving the warp threads up and down. The drive devices include a heald assembly 300, an upper roller 210, a lower roller 220, and a linear drive mechanism 400. The linear drive mechanism 400 includes an output rod 410. The linear drive mechanism 400 is used to convert rotational motion into linear motion so as to output linear motion through the output rod 410. The heald belt assembly 300 includes two heald belts 310 and two rows of heald wires 320. One heald belt 310 is wrapped around the upper roller 210 in an inverted U-shape, and the other heald belt 310 is wrapped around the lower roller 220 in a U-shape, so that the two ends of the two heald belts 310 are respectively arranged vertically and vertically. The two rows of heald wires 320 extend vertically and are arranged parallel between the two heald belts 310. The two ends of the two heald belts 310 are connected by a row of heald wires 320, so that the heald belt assembly 300 is circular in shape. The upper roller 210 and the lower roller 220 are used together to tension the heald belt assembly 300. Each heald wire 320 is provided with a thread hole 321, and different warp threads pass through the thread holes 321 of different heald wires 320. A through hole 311 is provided on the heald belt 310, and an output rod 410 passes through the through hole 311. The output rod 410 outputs a vertical linear motion to the heald belt 310, pulling the heald belt 310 up and down, causing the two rows of heald wires 320 connected to the end of the heald belt 310 to move up and down with the heald belt 310. This causes the warp threads passing through the two rows of heald wires 320 to move up and down. Because the heald belt assembly 300 is annular, when one row of heald wires 320 drives the warp threads to rise, the other row of heald wires 320 drives the warp threads to fall. The weft threads pass through the up and down moving warp threads to weave the tubular fabric.

[0036] This invention establishes a circular loom with the output rod 410 of the linear drive mechanism 400 and the heald belt 310 of the heald belt assembly 300 directly connected. The linear drive mechanism 400 converts the rotational motion into linear motion in the vertical direction of the heald belt 310, thereby causing the heald wires 320 connected to the heald belt 310 to pull the warp threads passing through the heald wires 320 in a reciprocating motion in the vertical direction. During the entire movement, the heald wires 320 only move in the vertical direction, pulling or pressing the warp threads upwards or downwards. This avoids excessive wear on the warp threads caused by repeated horizontal displacement of the heald wires 320, effectively protecting the warp threads while preventing the generation of a large amount of dust due to excessive wear of the warp threads. Furthermore, since the driving structure used to drive the heald belt assembly 300 is a linear drive mechanism 400, the output rod 410 can be directly inserted into the heald belt 310 for transmission. Each heald belt assembly 300 only needs to be equipped with two heald belts 310 to realize the up and down movement of two rows of heald wires 320, which simplifies the structure of the heald belt assembly 300 and reduces the manufacturing and processing difficulty of the heald belt assembly 300.

[0037] like Figure 2 and Figure 3As shown, a mounting block 330 is provided on the side of the heald belt 310 facing the linear drive mechanism 400. The mounting block 330 has a mounting hole 331, which is aligned with the through hole 311. The output rod 410 of the linear drive mechanism 400 passes through the mounting hole 331 and extends into the through hole 311 to move in conjunction with the heald belt 310. The mounting hole 331 on the mounting block 330 can increase the contact area between the output rod 410 and the heald belt assembly 300, so that when the output rod 410 moves up and down radially to drive the heald belt 310 up and down, it is not easy to damage the heald belt 310. At the same time, the mounting block 330 can fill the gap between the end face of the linear drive mechanism 400 and the side of the heald belt 310, preventing the heald belt 310 from shaking into the gap, making the up and down movement of the heald belt 310 more stable.

[0038] In this embodiment, the mounting block 330 and the heald belt 310 are detachably connected. The mounting block 330 is provided with locking members 332 located on both sides of the mounting hole 331. The two locking members 332 are locked to the heald belt 310 to fix the mounting block 330 onto the heald belt 310, preventing the mounting block 330 from rotating or moving relative to the heald belt 310. This ensures that the mounting hole 331 and the through hole 311 on the heald belt 310 are always aligned. If the mounting block 330 or the heald belt 310 is damaged, they can be separated for individual use. Replacing the two reduces maintenance and replacement costs. The locking component 332 can be any type of locking structure commonly available on the market. Preferably, the locking component 332 is a locking screw. The head of the locking screw is located on the side of the helical belt 310 away from the mounting block 330. The screw shank passes through the helical belt 310 and is threadedly connected to the mounting block 330 to lock it in place. This allows the head of the locking component 332 and the mounting block 330 to clamp the helical belt 310 together. Using a locking screw as the locking component 332 simplifies the structure of the locking component 332 and facilitates its installation and disassembly.

[0039] In this embodiment, a stop member 411 is provided at the end of the output rod 410 that passes through the heald belt 310. The stop member 411 is located on the side of the heald belt 310 away from the mounting block 330. The outer diameter of the stop member 411 is larger than the inner diameter of the through hole 311. The stop member 411 is detachably connected to the output rod 410. By abutting against the heald belt 310 on the outer periphery of the through hole 311, it prevents the output rod 410 from freely separating from the through hole 311, thus avoiding the inability of transmission between the two and ensuring stable transmission between the output rod 410 and the heald belt 310. This, in turn, ensures that the heald wire 320 drives the warp wire to move stably up and down. Preferably, the stop member 411 is a stop nut, and the stop nut is threadedly connected to the output rod 410. By using a retaining nut as the retaining element 411, the retaining element 411 and the output rod 410 can be installed and removed simply by rotating the retaining nut. The operation is convenient and simple. At the same time, the position of the retaining element 411 in the axial direction of the output rod 410 can also be adjusted by rotating the retaining nut. Even if there is a certain manufacturing error in the length of the output rod 410, it can still be ensured to abut against the helical belt 310 by rotating the retaining nut, thereby ensuring the limiting effect of the retaining element 411 on the output rod 410.

[0040] In this embodiment, the linear drive mechanism 400 further includes a gear ring 420, planetary gears 430, an input shaft 460, a connector 440, and a limiting member 450. The planetary gears 430 are disposed inside the gear ring 420, and their outer circumference meshes with the gear ring 420. The input shaft 460 is coaxially arranged with the gear ring 420 and is rotatably connected to the planetary gears 430 through a transmission member 470 fixed at its end, so as to drive the planetary gears 430 to rotate inside the gear ring 420. The limiting member 450 is disposed on the side of the gear ring 420 facing the heald belt 310 and is fixed on the gear ring 420. A sliding hole 451 is provided on the limiting member 450, which is strip-shaped and extends vertically along the radial direction of the gear ring 420. The output rod 410 extends horizontally and passes through the sliding hole 451. The two ends of the connector 440 are rotatably connected to the central shaft of the planetary gears 430 and the output rod 410, respectively. When the input shaft 460 drives the planetary gear 430 to rotate within the gear ring 420, as the planetary gear 430 meshes with the gear ring 420 at different positions, the planetary gear 430 rotates on its own axis while revolving around the central axis of the gear ring 420. This, in turn, drives the connecting piece 440, which is rotatably connected to the planetary gear 430, to rotate around the central axis of the planetary gear 430 and simultaneously undergo displacement in both the horizontal and vertical directions. Because the sliding hole 451 extends vertically, it can guide and limit the output rod 410, so that the connecting piece 440 can only transmit vertical displacement to the output rod 410, thereby driving the output rod 410 to slide up and down within the sliding hole 451. The sliding hole 451 on the limiting piece 450 can prevent the output rod 410 from pulling the heddle belt 310 laterally, making the transmission smoother. Of course, it is understandable that since the heald belt can only move in the vertical direction, in another embodiment, the limiting component may not be provided, and the output rod may be directly connected to the heald belt without passing through the guide of the sliding hole, which can also realize the up and down movement of the heald belt.

[0041] In this embodiment, the transmission component 470 is a transmission rod, with its two ends connected to the central shaft of the planetary gear 430 and the input shaft 460, respectively. In another embodiment, the transmission component can also be a sun gear fixed to the end of the input shaft, which meshes with the planetary gears.

[0042] like Figure 1 and Figure 2As shown, the circular loom includes a frame 100, on which an upper mounting base 110 and a lower mounting base 120 are provided. The upper mounting base 110 has an upwardly inclined upper slot 111, in which the shaft at the end of the upper roller 210 is engaged. The lower mounting base 120 has a downwardly inclined lower slot 121, in which the shaft at the end of the lower roller 220 is engaged. By setting the openings of the upper slot 111 and the lower slot 121 to face different directions, it is convenient to install the upper roller 210 and the lower roller 220, while ensuring that the upper roller 210 on the upper mounting base 110 and the lower roller 220 on the lower mounting base 120 have a certain amount of room for movement. This allows for adjustment of the tension of the heald belt assembly 300, preventing over-tensioning and ensuring that the heald belt assembly 300 is maintained at a suitable tension, thus protecting the heald belt assembly 300 and facilitating transmission.

[0043] Example 2:

[0044] The difference between this embodiment and Embodiment 1 is that in this embodiment, the mounting block and the heald belt are non-detachable. That is, the mounting block is fixed to the heald belt by means of adhesive bonding or other methods, so that once the mounting block and the heald belt are connected, the two cannot be separated. By making the mounting block and the heald belt non-detachable, the user can directly insert the output rod into the mounting hole and through hole without assembling the mounting block and the heald belt in advance when assembling the circular loom, reducing assembly steps and simplifying the assembly process.

[0045] Example 3:

[0046] The difference between this embodiment and Embodiment 1 is that, in this embodiment, the end of the output rod is provided with an annular groove. When the output rod is threaded onto the heald belt, the annular groove is located on the side of the heald belt away from the mounting block. The anti-reverse element is a retaining spring. The inner ring of the retaining spring is engaged in the annular groove, and the outer ring of the retaining spring extends out of the annular groove to abut against the heald belt. By using a retaining spring as the anti-reverse element and cooperating with the annular groove on the output rod, relative rotation can occur between the anti-reverse element and the output rod. Even if the output rod rotates slightly due to the friction between it and the connecting part, or if the retaining spring rotates due to vibration, the anti-reverse element will not move axially on the output rod, ensuring that the anti-reverse element is always stably abutting against the heald belt.

[0047] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
