Description

Technical Field

[0001] This utility model relates to the technical field of circular loom textiles, and in particular to a twill water-belt circular loom. Background Technology

[0002] A circular loom is a device that separates warp threads into layers according to a certain pattern to create openings. A shuttle carries the warp threads through these openings, causing the warp and weft threads to interweave and form a cylindrical fabric. The water-weave circular loom is one such device. Water-weave circular looms use different shaped dividing gears to separate the warp threads into layers according to different patterns, thus weaving water-weaves with different textures. Generally speaking, the different textures of water-weaves can be divided into two categories: plain weave and twill weave.

[0003] Plain weave, with its 1:1 warp and weft yarns interlacing, is characterized by its density and high strength. However, the excessive number of interlacing points can make the tape stiffer, and its density can also affect the penetration of adhesive layers in subsequent processes. Twill weave, with its 2:1 warp and weft yarn ratio, has fewer interlacing points under the same specifications and processes. Therefore, twill weave tape is more flexible and better facilitates adhesive penetration.

[0004] The prior art CN202510717898.2 discloses a twill weave circular loom including a first mounting frame and a main shaft, and further including: a cam, which is mounted on the main shaft and driven to rotate by the main shaft; the cam is provided with a drive rail; a palm frame assembly, each palm frame assembly including multiple palm threads for the warp threads to pass through; a slider assembly, the palm frame assembly being mounted on the slider assembly and driven to reciprocate linearly by the slider assembly; and a swing arm assembly, the swing arm assembly including a swing arm, one end of which is connected to the drive rail and driven to swing by the drive rail, and the other end of which is provided with a swing gap with the slider assembly so that the swing arm slides relative to the slider assembly and drives the slider assembly to reciprocate up and down.

[0005] In the aforementioned prior art, although a swing gap is set between the other end of the swing arm and the slider assembly, allowing the swing arm to slide relative to the slider assembly to drive the slider to move up and down reciprocally, in order to ensure that the swing arm and the slider assembly can slide, there needs to be a certain gap between the swing arm and the swing gap to avoid the swing arm and the slider from jamming and affecting the weaving efficiency of the circular loom. The existence of this gap will inevitably cause the swing arm and the slider assembly to rub against each other when the swing arm moves, which will affect the service life of the swing arm and the slider assembly and also generate noise.

[0021] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a twill water-weave circular loom, including a mounting frame 1 and a main shaft 2 and a hem frame assembly 3 mounted on the mounting frame 1. The main shaft 2 is rotatably mounted to the mounting frame 1, and the hem frame assembly 3 is slidably mounted in the vertical direction. A cam 21 is provided on the main shaft 2, and a drive rail 211 is provided on the cam 21. A swing arm assembly 4 is hinged to the mounting frame 1. The swing arm assembly 4 is located between the main shaft 2 and the hem frame assembly 3. One end of the swing arm assembly 4 is connected to the drive rail 211, and the other end is hinged to the hem frame assembly 3 through a connecting rod 43. The rotation of the main shaft 2 causes the drive rail 211 to drive the swing arm assembly 4 to swing and drive the hem frame assembly 3 to move up and down reciprocally. Specifically, in this embodiment, as shown... Figure 2As shown, cam 21 has a specific profile curve to convert the rotational motion of spindle 2 into periodic oscillation. Specifically, when spindle 2 rotates, it drives cam 21 to rotate synchronously. The drive rail 211 on cam 21 drives rocker arm assembly 4 to oscillate around the hinge point. The end of rocker arm assembly 4 away from cam 21 forms a hinged linkage with frame assembly 3 through connecting rod 43. The oscillation amplitude of rocker arm 42 is converted into the vertical displacement of frame assembly 3 through connecting rod 43. The rocker arm assembly 4 is hinged to the mounting bracket 1, to the connecting rod 43, and to the frame assembly 3. The relative motion between the components is achieved only through a rotary joint, eliminating the need for hinges. Compared to the prior art CN202510717898.2, which uses a swing gap to achieve the reciprocating motion of the swing arm assembly 4 driving the brown frame assembly 3, the rotary transmission chain constructed through three hinge points transforms sliding friction into rolling friction, resulting in a more uniform distribution of contact stress and effectively reducing localized wear. Simultaneously, the motion accuracy of the rotary pair is unaffected by assembly gaps, maintaining stable transmission performance over a long period. Eliminating sliding friction between transmission components significantly reduces motion noise and extends the service life of key components. The hinged transmission structure avoids vibration problems caused by traditional clearance fits, making the lifting and lowering motion of the brown frame assembly 3 smoother and more reliable. The low-friction characteristics of the rotary pair also reduce drive power loss, contributing to improved equipment energy efficiency.

[0023] In this embodiment, as Figure 3 As shown, the heddle frame assembly 3 includes a heddle rod 31 and heddle wires 32. The heddle wires 32 are mounted on the heddle rod 31 and allow the warp threads to pass through. The heddle rod 31 is provided with a connecting part 311. One end of the connecting rod 43 is hinged to the swing arm assembly 4, and the other end is hinged to the connecting part 311. Specifically, by setting the heddle frame assembly 3 in the form of a heddle rod 31 and heddle wires 32, the heddle rod 31 is slidably connected to the mounting frame 1 and hinged to the swing arm assembly 4. This ensures that when the cam 21 rotates, the drive rail 211 can drive the swing arm assembly 4 to swing, thereby causing the heddle rod 31 to move up and down. The warp threads pass through the heddle wires 32, and the up and down movement of the heddle rod 31 in turn drives the warp threads to move up and down, ensuring the stability of the circular loom weaving.

[0024] In another embodiment, such as Figure 1 and Figure 3As shown, there are three sets of brown frame assemblies 3 radially distributed along the main shaft 2, three sets of cams 21 axially distributed along the main shaft 2, and three sets of rocker arm assemblies 4 corresponding to the cams 21. The uppermost cam 21 is connected to the innermost set of brown frame assemblies 3 through the uppermost set of rocker arm assemblies 4. The middle cam 21 is connected to the middle brown rod 31 assembly through the middle set of rocker arm assemblies 4. The lowermost cam 21 is connected to the outermost brown frame assemblies 3 through the lowermost set of rocker arm assemblies 4. Specifically, the brown frame assemblies 3 are arranged in three sets radially along the main shaft 2, so that the warp yarns passing through the three sets of brown frame assemblies 3 present the following form: the warp yarns processed by the outermost brown frame assemblies 3 are above the weft yarns, passing through the middle After the warp yarns of the innermost palm frame assembly 3 are processed, they are above the weft yarns. After the warp yarns of the innermost palm frame assembly 3 are processed, they are below the weft yarns, so that the warp yarns can form an up-down pattern relative to the weft yarns. As the cam 21 rotates, the rocker arm assembly 4 swings, and the warp yarns switch to down-up-up relative to the weft yarns. The cam 21 continues to rotate, driving the rocker arm assembly 4 to swing, and the warp yarns switch to up-down-up relative to the weft yarns. Then, it moves back and forth, thus weaving a twill weave. Specifically, the rocker arm assembly 4 and the palm frame assembly 3 are offset in the radial direction of the main shaft 2 through the connecting part 311. The hinge point of the connecting part 311 and the connecting rod 43 avoids the palm rod 31 in the circumferential direction of the main shaft 2, so as to avoid the rocker arm assembly 4 colliding with the palm rod 31 during the swinging process and affecting the up-down reciprocating motion of the palm rod 31.

[0025] Because the three sets of frame assemblies 3 are radially distributed along the main shaft 2, the distance between the outer wheel of the cam 21 and the frame is different. Since the rocker arm assembly 4 is of the same specification, its radial length along the main shaft 2 remains constant. Therefore, to ensure that the rocker arm assembly 4 can stably swing and drive the frame assembly 3 to reciprocate up and down, as follows... Figure 1 and Figure 2 As shown, the diameters of the three cams 21 gradually increase from top to bottom, ensuring that the rocker arm assembly 4 remains stably connected to the drive rail 211 after the brown frame assembly 3 moves radially outward; in another embodiment, as... Figure 1 and Figure 4 As shown, the hinge centers of the three sets of rocker arm assemblies 4 are gradually moved outward from top to bottom. Specifically, the hinge point between the bottommost rocker arm assembly 4 and the mounting frame 1 is outside the hinge point between the middle rocker arm assembly 4 and the mounting frame 1, and so on. Specifically, for rocker arm assemblies 4 of the same specification, the outward movement of the hinge point can ensure that the outer end of the rocker arm assembly 4 and the connecting part 311 can be hinged together, ensuring that the rotation of the cam 21 drives the rocker arm assembly 4 to swing, and the rocker arm assembly 4 can drive the heddle rod 31 and the heddle 32 to move up and down reciprocally, thereby driving the warp threads to move up and down reciprocally for weaving.

[0026] In another embodiment, such as Figure 1 and Figure 5As shown, the rocker arm assembly 4 includes a rocker arm seat 41 and a rocker arm 42, specifically, as... Figure 1 As shown, the mounting bracket 1 includes a first mounting bracket 11 and a second mounting bracket 12, as follows: Figure 3 As shown, the first mounting bracket 11 includes a main mounting bracket 111 and a mounting plate 112 located above the main mounting bracket 111. The main shaft 2 is rotatably mounted on the main mounting bracket 111, the heddle rod 31 is slidably mounted on the main mounting bracket 111 and the mounting plate 112, and the heddle wire 32 is located above the mounting plate 112. Figure 4 As shown, the second mounting bracket 12 includes a first mounting plate 121, a second mounting plate 122, and a third mounting plate 123 distributed along the vertical direction. The first mounting plate 121, the second mounting plate 122, and the third mounting plate 123 are located between the main mounting bracket 111 and the mounting plate 112. The first mounting plate 121, the second mounting plate 122, and the third mounting plate 123 are all provided with mounting holes radially distributed along the main shaft 2. The rocker arm seat 41 is connected to the first mounting plate 121, the second mounting plate 122, or the third mounting plate 123 by screws. Plates 123 are fastened together; specifically, the rocker arm seat 41 on the first mounting plate 121 is installed with screws into the innermost mounting hole, the rocker arm seat 41 on the second mounting plate 122 is installed with screws into the middle mounting hole, and the rocker arm seat 41 on the third mounting plate 123 is installed with screws into the outermost mounting hole; the rocker arm 42 is rotatably mounted on the rocker arm seat 41, and the rigid support structure of the rocker arm seat 41 improves the accuracy of the movement trajectory of the brown frame assembly 3 and improves the uniformity of the fabric weaving; such as Figure 5 As shown, one end of the swing rod 42 is provided with a swing groove 422, which is connected to the cam 21 by insertion, so that the swing rod 42 is connected to the drive rail 211, ensuring that the drive rail 211 drives the swing rod 42 to swing. The other end of the swing rod 42 is hinged to the connecting rod 43, ensuring that the swing rod 42 can drive the palm rod 31 to reciprocate in the up and down direction on the main mounting frame 111 and the mounting plate 112 when swinging. The insertion connection between the swing groove 422 and the cam 21 prevents the swing rod 42 from wobbling in the axial direction of the swing rod 42 rotation axis when swinging, thus affecting the up and down reciprocating motion of the palm rod 31.

[0027] To reduce friction between the rocker arm 42 and the cam 21, such as Figure 5As shown, the end of the rocker arm 42 is provided with two rollers 421. The two rollers 421 are distributed vertically at the end of the rocker arm 42 to form a swing groove 422. When the swing groove 422 is inserted into the cam 21, the two rollers 421 contact the upper and lower side walls of the cam 21. Specifically, the two rollers 421 contact the upper and lower side walls of the drive rail 211 to ensure that when the cam 21 rotates with the main shaft 2, the drive rail 211 drives the rocker arm 42 to rotate through contact with the rollers 421. When the cam 21 rotates, the rocker arm 42 and the drive rail 211 make rolling contact through the rollers 421, which reduces the damage to the rocker arm 42 and the cam 21 caused by friction, thereby improving the service life of the cam 21 and the rocker arm 42.

[0028] In another embodiment, such as Figure 6 As shown, to ensure that the swing arm 42 can swing stably on the swing arm seat 41, the upper end of the swing arm seat 41 has a first mounting part 411 and a second mounting part 412. The first mounting part 411 and the second mounting part 412 are spaced apart to form a receiving space 413 for accommodating the swing arm 42. The swing arm 42 is rotatably connected to the first mounting part 411 and the second mounting part 412. The first mounting part 411 is located at the upper end of the swing arm seat 41 to support the rotation of the swing arm 42, and its function is to provide a stable rotation fulcrum for the swing arm 42. The second mounting part 412 is an auxiliary support structure arranged parallel to the first mounting part 411. Specifically, it can be implemented by using a symmetrical block of the same material as the first mounting part 411. The first mounting part 411 and the second mounting part 412 together constitute a double support structure to enhance the axial positioning of the swing arm 42. The receiving space 413 is a cavity area formed by the distance between the first mounting part 411 and the second mounting part 412, which can be adjusted by... The distance between the first mounting part 411 and the second mounting part 412 is made greater than the maximum width of the swing trajectory of the swing arm 42. Its function is to provide an interference-free motion path for the swing of the swing arm 42. When the main shaft 2 drives the cam 21 to rotate, the end of the swing arm 42 near the cam 21 is driven by the drive track 211 to generate periodic swing. Due to the existence of the accommodating space 413, the swing arm 42 will not contact the swing arm seat 41 during the swing. The rotation axis of the swing arm 42 is jointly supported by the first mounting part 411 and the second mounting part 412. The double support structure formed by the first mounting part 411 and the second mounting part 412 makes the swing arm 42 keep the rotation axis stable when it is subjected to the driving force of the cam 21, avoiding radial offset caused by single-point support. The swing amplitude of the swing arm 42 is limited within the accommodating space 413, thereby eliminating the possibility of rigid collision between the swing arm 42 and the side wall of the first mounting part 411 or the second mounting part 412.

[0029] Furthermore, in order to improve the stability of the connection between the rocker arm 42 and the first mounting part 411 and the second mounting part 412, such as... Figure 6As shown, the swing arm 42 is provided with a mounting rod 44, which is rotatably connected to the swing arm 42. One end of the mounting rod 44 is fixedly connected to the first mounting part 411, and the other end is fixedly connected to the second mounting part 412. Specifically, the mounting rod 44 serves as an independent support for the swing arm 42, the first mounting part 411, and the second mounting part 412. By fixing one end of the mounting rod 44 to the first mounting part 411 and the other end to the second mounting part 412, it is ensured that the swing arm 42 can be stably installed on the swing arm seat 41, thereby ensuring the stability of the swing arm 42.

[0030] To ensure the stability of the connection between the mounting rod 44 and the first mounting part 411 and the second mounting part 412, such as Figure 6 As shown, both the first mounting part 411 and the second mounting part 412 are provided with receiving grooves 414. Both ends of the mounting rod 44 are placed in the receiving grooves 414. The mounting rod 44 has a mounting surface 441. Fasteners pass through the mounting surface 441 and are fastened to the first mounting part 411 or the second mounting part 412. The receiving groove 414 is a concave structure located at the upper end of the first mounting part 411 and the second mounting part 412, specifically a U-shaped groove, used for positioning the mounting rod 44 before fastening. The mounting surface 441 can be formed into a plane by milling or casting. The mounting surface 441 facilitates the machining of through holes in the mounting rod 44, thereby facilitating the fasteners to pass through the mounting rod 44 and be fastened to the first mounting part 411 or the second mounting part 412. Specifically, when assembling the swing arm assembly 4, both ends of the mounting rod 44 are respectively embedded in the receiving grooves 414 of the first mounting part 411 and the second mounting part 412. The mounting rod 44 is positioned by the groove wall to prevent the hinge point of the swing arm 42 from deviating. The mounting rod 44 is rotated so that the mounting surface 441 faces upward. Then, the fastener is placed in the through hole and tightened downward to the first mounting part 411 or the second mounting part 412. After the fastener is installed in place, it abuts against the mounting surface 441, so that the pre-tightening force applied by the fastener forms a surface contact fixation, avoiding local stress concentration caused by point contact. During the high-frequency swing of the swing arm 42, the mounting surface 441 abuts against the fastener, improving the abutting force of the fastener, thereby improving the stability of the mounting rod 44.

[0031] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
