Description

Technical Field

[0001] This utility model relates to a circular loom, specifically 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 weave tape stiffer, and its density can also hinder the penetration of the adhesive layer in subsequent processes. Twill weave, with a 2:1 warp and weft yarn interlacing ratio, has fewer interlacing points than plain weave for the same specifications and processes. Therefore, twill weave weave tape is more flexible and better facilitates adhesive penetration. Existing twill weave circular looms typically use a large cam to drive the heald frame structure in a reciprocating motion.

[0004] The maximum outer diameter of the large cam is about 1200mm. Due to its large size and weight, the motor and other supporting parts required to drive its rotation are also relatively large, resulting in high energy consumption. Moreover, due to the large inertia when the large cam rotates, the energy consumption is relatively high. Considering safety and actual production, the rotation speed of the large cam is usually about 100 revolutions per minute, which makes the current weaving efficiency relatively low. Utility Model Content

[0005] To address the problems in existing water-weave circular looms where the large cam rotates slowly, resulting in low processing efficiency and potential for the large cam to oscillate during processing, this invention provides a twill water-weave circular loom.

[0006] The technical solution of this utility model is: a twill water-weave circular loom, comprising a first mounting frame and a main shaft, and further comprising:

[0007] A cam is mounted on a main shaft and driven to rotate by the main shaft; the cam is provided with a drive track.

[0008] Brown frame assembly, each brown frame assembly includes multiple warp threads passing through brown fibers;

[0009] The slider assembly, wherein the brown frame assembly is disposed on the slider assembly and is driven by the slider assembly to reciprocate linearly;

[0010] A rocker arm assembly includes a rocker arm, one end of which is connected to a 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 rocker arm slides relative to the slider assembly and drives the slider assembly to reciprocate up and down.

[0011] As a further improvement of this utility model, the brown frame assembly is set in three groups as a whole, with each group of brown frame assemblies corresponding to a group of slider assemblies. The rocker arm assembly is set in three groups as a whole, with each group of slider assemblies being driven by a group of rocker arm assemblies to reciprocate linearly.

[0012] As a further improvement of this utility model, three sets of brown frame assemblies are arranged radially along the cam, and three sets of rocker arm assemblies are arranged vertically along the parallel cam axis. The cam has three drive tracks, which are used to drive three different sets of rocker arm assemblies to swing.

[0013] As a further improvement of this utility model, it also includes a second mounting frame, on which multiple sets of brown frame components are provided. The multiple sets of brown frame components are arranged in three groups as a whole and are evenly distributed around the second mounting frame. The first mounting frame is provided with a first fixing frame and a second fixing frame, and three different swing rod components are respectively provided on the first mounting frame, the first fixing frame, and the second fixing frame.

[0014] As a further improvement of this utility model, the swing arm assembly includes:

[0015] A swing arm seat is used for installation and fixation; the swing arm is mounted on the swing arm seat and swings relative to the swing arm seat.

[0016] A swing arm wheel is located at one end of the swing arm. There are two swing arm wheels, which cooperate with each other to form a swing groove that is adapted to the drive track. The two swing arm wheels are located on the upper and lower sides of the drive track and make the swing arm swing up and down with the trajectory of the drive track.

[0017] As a further improvement of this utility model, the swing arm is provided with a pulley, the slider assembly includes a pressure plate, the pressure plate is provided with a sliding groove, the pulley is disposed in the sliding groove of the pressure plate and cooperates with the sliding groove to form a swing gap; the swing arm swings around the swing arm seat under the influence of the driving track trajectory and drives the pulley to slide relative to the sliding groove and drives the pressure plate to move vertically reciprocating.

[0018] As a further improvement of this utility model, the swing rod is provided with a swing block, the slider assembly includes a pressure plate, the swing block is located on the outside of the pressure plate and forms a swing gap, the swing rod is affected by the drive track trajectory and swings around the swing rod seat and drives the swing block to slide relative to the pressure plate and drives the pressure plate to move vertically back and forth.

[0019] As a further improvement of this utility model, the slider assembly includes a slider, a brown rod, and a limiting rod. The slider drives the corresponding brown frame assembly to move synchronously through the brown rod. The slider is provided with a guide hole, and the limiting rod passes through the guide hole to guide and limit the vertical movement of the slider.

[0020] As a further improvement of this utility model, the slider is provided with a connecting hole for different groups of palm rods to pass through.

[0021] As a further improvement of this utility model, the cam is integrally cast and the drive track is milled out, and the distance from the axis of the cam to the outer surface of the drive track is 400-600mm.

[0022] The beneficial effects of this invention are that the rocker arm assembly reliably converts the rotation of the cam into the swing of the rocker arm. Simultaneously, the swing gap ensures that the rocker arm's swing is reliably converted into the vertical up-and-down movement of the frame assembly without the frame assembly swaying, thus preventing the rocker arm's swing from causing tension or relaxation in the frame assembly. This invention also features a simple structure, convenient assembly, reliable operation, and long service life. Attached Figure Description

[0034] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0035] Depend on Figure 1 Combination Figure 2-10 As shown, a twill water-weave circular loom includes a first mounting frame 1 and a main shaft 2, and further includes:

[0036] Cam 3 is mounted on main shaft 2 and driven to rotate by main shaft 2; cam 3 is provided with drive rail 31.

[0037] The brown frame assembly 4 includes multiple warp threads passing through brown filaments 41; specifically, the brown filaments 41 are provided with thread holes 411 for the warp threads to pass through.

[0038] Slider assembly 5, wherein the brown frame assembly 4 is disposed on slider assembly 5 and is driven by slider assembly 5 to reciprocate linearly;

[0039] The rocker arm assembly 6 includes a rocker arm 61. One end of the rocker arm 61 is connected to the drive rail 31 and driven to swing by the drive rail 31. The other end has a swing gap 62 between it and the slider assembly 5, allowing the rocker arm 61 to slide relative to the slider assembly 5 and drive the slider assembly 5 to reciprocate up and down. The advantages of this invention are that the rocker arm assembly reliably converts the rotation of the cam into the swing of the rocker arm. Simultaneously, the swing gap ensures that the swing of the rocker arm reliably converts the vertical movement of the frame assembly without causing the frame assembly to swing, thus preventing tension and relaxation of the frame assembly due to the rocker arm's swing. This invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life. In fact, the original twill weave circular loom used a large cam to directly drive the heald frame assembly up and down. The maximum outer diameter of the large cam was 1200mm. However, the distance from the axis of the cam 3 in this invention to the outer surface (maximum outer diameter) of the drive track 31 is 400-600mm. For circular looms of the same size, the cam in this invention is only half the size of the large cam. The specific transmission method is also different. The existing large cam directly drives the slider (fixed heald rod) to move, while the small cam in this invention drives the slider (fixed heald rod) to move through a swing arm. Simply making the large cam smaller would cause more problems with force and lubrication. This allows the cam in this invention to be smaller in size, consume less energy than other circular looms of the same size, and achieve a cam speed of 160 minutes per minute, resulting in higher processing efficiency.

[0040] The brown frame assembly 4 is configured in three groups as a whole, with each group of brown frame assemblies 4 corresponding to a group of slider assemblies 5. The rocker arm assembly 6 is also configured in three groups as a whole, with each group of slider assemblies 5 driven by a group of rocker arm assemblies 6 to reciprocate linearly. This allows each set to produce a warp-to-weft interlacing ratio of 2:1, where the warp yarns relative to the weft yarns can form an up-down-up pattern (the warp yarns passing through the three brown frame assemblies are above the weft yarns after processing the outermost brown frame assembly, above the weft yarns after processing the middle brown frame assembly, and below the weft yarns after processing the innermost brown frame assembly, and so on). When the cam rotates, the rocker arms of the three rocker arm assemblies swing, switching the warp yarns relative to the weft yarns to down-up-up; as the cam continues to rotate, the rocker arms of the three rocker arm assemblies swing, switching the warp yarns relative to the weft yarns to up-down-up, and then reciprocating. The use of three groups of warp yarns, woven from interlaced brown fibers to create a twill flexible hose, provides good flexibility and facilitates adhesive penetration. Specifically, three sets of brown frame assemblies 4 are arranged radially along the cam, and three sets of rocker arm assemblies 6 are arranged vertically along the axis of the parallel cam 3. The cam 3 has three drive rails 31, each used to drive one of the three different sets of rocker arm assemblies 6 to swing. More specifically, each slider assembly includes a brown bar, with three brown bars arranged radially along the cam, forming one set. Multiple sets of brown frame assemblies are mounted on the second mounting bracket. That is, when the cam rotates, the drive rails can drive the three sets of rocker arm assemblies of the same set to swing, thereby driving the slider and brown bars to reciprocate linearly. The brown bars and brown frame assemblies move smoothly up and down, are easy to operate, and reduce power loss and wear on machine parts.

[0041] This utility model also includes a second mounting bracket 7, above which are multiple sets of brown frame components 4, arranged in groups of three and evenly distributed circumferentially above the second mounting bracket 7; the first mounting bracket 1 is provided with a first fixing bracket 11 and a second fixing bracket 12, and three different swing arm components 6 are respectively mounted on the first mounting bracket 1, the first fixing bracket 11, and the second fixing bracket 12. This structure facilitates the installation of the swing arm components, is simple in structure, easy to assemble, and makes reasonable use of the internal space of the product.

[0042] The swing arm assembly 6 includes:

[0043] The swing arm seat 63 is used for installation and fixation; the swing arm 61 is disposed on the swing arm seat 63 and swings relative to the swing arm seat 63.

[0044] A swing arm wheel 64 is located at one end of the swing arm 61. There are two swing arm wheels 64, which cooperate to form a swing groove 65 adapted to the drive track 31. The two swing arm wheels 64 are located on the upper and lower sides of the drive track 31, allowing the swing arm 61 to swing up and down along the trajectory of the drive track 31. In this invention, the swing arm drives the slider assembly to move vertically up and down. The slider is reliably limited by the limiting rod. The slider and the frame can only move up and down, without any swinging. This avoids the swinging of the swing arm causing the frame assembly to swing, resulting in tension and relaxation, which would affect product quality.

[0045] The swing arm 61 is equipped with a pulley 66, and the slider assembly 5 includes a pressure plate 51. The pressure plate 51 has a sliding groove 52, and the pulley 66 is disposed in the sliding groove 52 of the pressure plate 51 and cooperates with the sliding groove 52 to form a swing gap 62. The swing arm 61 swings around the swing arm seat 63 under the influence of the trajectory of the drive track 31, which drives the pulley 66 to slide relative to the sliding groove 52 and drives the pressure plate 51 to move vertically reciprocally. This structure ensures that the swing trajectory of the swing arm does not affect the slider assembly, allowing the slider assembly to move reliably vertically. Specifically, the swing arm 61 is mounted on the swing arm seat 63 via a swing arm shaft 67, and a first bearing 68 is provided between the swing arm shaft 67 and the swing arm 61.

[0046] The swing arm 61 is equipped with a swing block 69, and the slider assembly 5 includes a pressure plate 51. The swing block 69 is located outside the pressure plate 51 and forms a swing gap 62. The swing arm 61 swings around the swing arm seat 63 under the influence of the drive track 31, causing the swing block 69 to slide relative to the pressure plate 51 and causing the pressure plate 51 to move vertically reciprocally. This structure ensures that the swing trajectory of the swing arm does not affect the slider assembly, allowing the slider assembly to move reliably vertically. Specifically, in Embodiment 1, the pulley is placed in the sliding groove, and there is a radial movement distance between the pulley and the pressure plate along the cam. In Embodiment 2, a groove is provided on the swing block, and the pressure plate is in the groove, with a radial movement distance between the swing block and the pressure plate along the cam. This ensures that the swing of the swing arm can reliably drive the slider to slide without interference.

[0047] The slider assembly 5 includes a slider 53, a brown rod 54, and a limiting rod 55. The slider 53 drives the corresponding brown frame assembly 4 to move synchronously via the brown rod 54. The slider 53 is provided with a guide hole 532, and the limiting rod 55 passes through the guide hole 532 to guide and limit the vertical movement of the slider 53. The limiting rod can limit the movement of the slider, prevent the slider from swinging, and thus prevent the brown rod from swinging.

[0048] The slider 53 is provided with connecting holes 531 for different groups of palm rods 54 to pass through. This allows other palm rods to limit the slider, enabling it to slide up and down. In practice, the topmost slider can have three palm rods passing through it, with one moving synchronously with the slider and the other two driven by the sliders of the two lower slider assemblies. The middle layer slider can have two palm rods passing through it, with one moving synchronously with the slider and the other driven by the sliders of the lower slider assemblies. The bottommost slider can have one palm rod passing through it, moving synchronously with the slider and passing through the two upper sliders. Alternatively, for better synchronization of components, each group can have three connecting holes.

[0049] The cam 3 is integrally cast and the drive track 31 is milled out. The distance from the axis of the cam 3 to the outer surface of the drive track 31 is 400-600mm. This allows for milling out the drive track as needed, controlling the swing amplitude of the rocker arm, i.e., controlling the vertical height of the hemp rod. The overall casting structure is simple, easy to process, and cost-effective. The cam of this invention is only half the size of the cam in the same machine, resulting in a smaller cam size. Compared to other circular looms, this invention has lower energy consumption, and the cam's rotation speed can reach 160 minutes per minute, meaning higher processing efficiency.
