Description

Technical Field

[0001] The utility model belongs to the technical field of textile equipment, in particular to a multi-axial knitting device of a high-speed warp knitting machine. Background Art

[0002] The core feature of a multi-axial high-speed warp knitting machine is its ability to interweave warp and weft in multiple directions simultaneously. Traditional uniaxial warp knitting machines can only interweave yarns in a single direction. Multi-axial warp knitting machines, equipped with multiple axial (e.g. longitudinal, transverse, diagonal, etc.) control systems, can achieve more complex fabric structures. The warp and weft yarns of the machine are precisely positioned and adjusted by computer control systems and automation systems, ensuring fabric quality and production efficiency.

[0003] Current multi-axial high-speed warp knitting machines reinforce the edges of the fabric during processing to form a trim. After processing, the fabric is reeled onto a take-up drum. However, the take-up drum is mostly flat and cylindrical. When the fabric is stretched and reeled, the thicker edges of the fabric bear the tension of the entire fabric, resulting in uneven tension and tilted fabric grain, which affects subsequent processing. To address this problem, we have developed a multi-axial weaving device for high-speed warp knitting machines to address this issue. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-axial weaving device for a high-speed warp knitting machine. By cooperating with an expansion component and an adjustment component, the utility model solves the problem in the prior art that the tension of the fabric is not uniform when the multi-axial high-speed warp knitting machine receives the fabric, which affects the subsequent processing.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions.

[0007] The utility model is further configured such that the expansion component further includes a dual-axis motor, the dual-axis motor is arranged inside the rotating rod, both output ends of the dual-axis motor are fixedly connected to screws, and the surface of the screw is threadedly connected to a movable sleeve.

[0010] The utility model is further configured such that the top and the bottom of the movable sleeve are fixedly connected with sliders, and the sliders are slidably connected to the inner wall of the rotating rod.

[0011] The utility model is further configured such that the top output end of the hydraulic rod is fixedly connected to a moving block, and one side of the moving block is fixedly connected to the movable frame.

A movable shell 5 is provided on the surface of the rotating rod 4, and an extension piece 6 is fixedly connected to one side of the movable shell 5, and an adjustment rod 7 is movably connected to the other side of the movable shell 5; an adjustment component is provided on the top of the base 1, and the adjustment component includes a movable frame 8, which is provided on the top of the base 1, and an auxiliary roller 9 is movably connected inside the movable frame 8. A hydraulic rod 10 is fixedly connected to the top of the base 1.

[0026] Specifically: The core components of the multi-axis warp knitting machine body 2 usually include: a frame, a needle bed, a yarn rack, a yarn guide, needles, a comb, a drive system, a control system, etc. The multi-axis warp knitting machine controls the yarn through multiple independently controlled axes (such as longitudinal, transverse, and oblique directions) to weave different fabric structures. It is an existing mature technology application. There are three extension pieces 6, and they are arranged in a circle with the rotating rod 4 as the axis. The hydraulic rod 10 can drive the movable frame 8 and the auxiliary roller 9 to move up and down, and the winding tension of the fabric can be adjusted.

[0027] Example 2

[0028] See also Figure 1-5On the basis of the first embodiment, the expansion component further includes a dual-axis motor 11, which is arranged inside the rotating rod 4. The output ends on both sides of the dual-axis motor 11 are fixedly connected to screws 12, and the surface of the screws 12 is threadedly connected to a movable sleeve 13. The other end of the adjusting rod 7 is movably connected to the movable sleeve 13. The threads on the surfaces of the two sets of screws 12 are opposite. A support rod 14 is slidably connected to the inside of the movable shell 5. One end of the support rod 14 is fixedly connected to a cross bar 15, and the other end of the cross bar 15 is fixedly connected to the inner wall of the rotating rod 4. The top and bottom of the movable sleeve 13 are fixedly connected to sliders 16, and the slider 16 is connected to the rotating rod 4. The inner wall of the rod 4 is slidably connected, and the top output end of the hydraulic rod 10 is fixedly connected to a moving block 17, and one side of the moving block 17 is fixedly connected to the movable frame 8. The surface of the rotating rod 4 is movably connected with a vertical plate 18, and the bottom of the vertical plate 18 is fixedly connected to the base 1. A driving motor 19 is installed on the rear side of the vertical plate 18, and the output end of the driving motor 19 is fixedly connected to the rotating rod 4. A pressure roller 20 is provided on the top of the winding drum 3, and the front and rear sides of the pressure roller 20 both penetrate into the interior of the vertical plate 18. A baffle 21 is provided on the top of the pressure roller 20, and the top of the baffle 21 is fixedly connected to the moving rod 22, and a spring 23 is provided on the surface of the moving rod 22.

[0029] Specifically: there are two groups of auxiliary rollers 9, which are respectively arranged at the top and bottom of the cloth. The dual-axis motor 11 can drive the two groups of screws 12 to rotate at the same time. The threads on the surfaces of the two groups of screws 12 are opposite. Under the drive of the dual-axis motor 11, the two groups of movable sleeves 13 can be driven to move relative to and oppositely. The movable shell 5 is connected to the cross bar 15 through the support rod 14. When the three groups of expansion pieces 6 move relative to each other, it can slide along the surface of the support rod 14 to play a guiding role. The driving motor 19 can drive the rotating rod 4 to rotate to reel in the cloth. The spring 23 has the function of compressing and storing energy, which can elastically support the pressure roller 20 and press down the cloth to improve the fit between the cloth and the winding drum 3.

[0030] The working principle of the present utility model is as follows: the staff starts the multi-axis warp knitting machine body 2 through an external controller to process the fabric, and fixes one end of the fabric after processing by the multi-axis warp knitting machine body 2 to the winding drum 3 and the expansion piece 6, and then starts the drive motor 19. The drive motor 19 cooperates with the rotating rod 4 to drive the winding drum 3 and the expansion piece 6 to rotate, and the inner side of the fabric is wound by the winding drum 3, and the edges and corners of the fabric are wound by the expansion piece 6. The diameter of the three groups of expansion pieces 6 is smaller than the winding drum 3, so thicker fabric edges and corners can be wound.

[0031] As the fabric is rolled up, the edges and corners of the fabric will continue to stack and the thickness will increase. At this time, the dual-axis motor 11 can be started, and the dual-axis motor 11 cooperates with the screw 12 to drive the movable sleeve 13 to move. The movable sleeve 13 cooperates with the adjusting rod 7 to drive the movable shell 5 to move. The movable shell 5 drives the three groups of expansion pieces 6 to move relative to each other, and gradually reduces the diameter of the three groups of expansion pieces 6, so that the edges and corners of the fabric are always flush with the inside, maintaining the uniformity of the tension and improving the flatness during rolling.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.
