Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to a transverse movement device for a warp knitting machine. Background Technology

[0002] A warp knitting machine is a type of machinery used to produce knitted fabrics, especially suitable for manufacturing fabrics with high density, high strength, and good dimensional stability. Warp knitting machines use longitudinally arranged yarns (i.e., warp yarns), which are woven into fabric through a series of needles. This allows for continuous, seamless fabric production and can accommodate yarns of various materials, making it widely used in the textile industry.

[0003] The lateral movement device is an important component of warp knitting machinery, primarily responsible for controlling and realizing the lateral movement of yarns to complete the fabric weaving process. During warp knitting, the lateral movement device ensures that each yarn moves along a preset path and pattern, thereby forming the desired fabric structure. Chinese invention application CN 104452087 A discloses an electronic guide bar lateral movement device for a multi-comb warp knitting machine. This device consists of multiple lateral movement transmission units; each unit includes a servo motor, a motor mounting base, a coupling, a ball screw pair, a nut connector, a fixed guide rod, a movable guide rod, a guide bar top ball, a guide bar top rod, a tension spring, and a guide bar. The servo motor drives the movable guide rod left and right via the ball screw pair, which in turn drives the guide bar left and right via the guide bar top rod. According to the patent documents, such a structural design requires that the output shaft of the servo motor and the ball screw pair have good installation concentricity. At the same time, the output shaft of the servo motor, the ball screw pair, the fixed guide rod and the movable guide rod should be installed in parallel and kept straight with the guide bar. This makes installation and debugging difficult, and the overall structure is complex with a large drive structure size, making it unsuitable for some small warp knitting machines. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a transverse movement device for warp knitting machines. This device simplifies the structure, thereby reducing the number of parts and lowering costs, while also making the device more compact, applicable to a wider range of machine models, and easier to assemble and debug.

[0005] The technical solution to achieve the purpose of this utility model is:

[0006] A warp knitting machine traverse device includes a guide bar assembly and a linear drive mechanism. The guide bar assembly is slidably arranged in the horizontal direction. The linear drive mechanism is fixedly arranged and connected to the guide bar assembly by a top rod and a tensioning assembly. The top rod is parallel to the tensioning assembly, and its two ends are respectively rotatably engaged with the output end of the linear drive mechanism and the guide bar assembly. It is kept in close contact with the guide bar assembly and the linear drive mechanism by the tensioning assembly. The linear drive mechanism is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0007] Furthermore, one end of the tensioning component is connected to the comb assembly, and the other end is rotatably connected to the output end of the linear drive mechanism.

[0008] Furthermore, the output end of the linear drive mechanism is fixedly connected to a first top block, and a second top block is fixedly mounted on the comb assembly. The second top block and the first top block are respectively fixedly mounted with a first top head and a hook arranged opposite to each other. The tensioning assembly includes a steel wire rope and a pull tube that are elastically connected. The other end of the pull tube is provided with a first spherical groove that is adapted to the first top head. The first top head is rotatably disposed in the first spherical groove. The other end of the steel wire rope is fitted onto the hook.

[0009] Furthermore, a pull rod is connected to the end of the wire rope. The pull rod is inserted into the pull tube and a limiting part is fixedly installed at its end. A pre-compressed spring sleeved on the pull rod is connected between the limiting part and the end of the pull tube near the wire rope.

[0010] Furthermore, the end of the pull rod is provided with a connecting part arranged opposite to each other, and a rolling part is rotatably connected between the two connecting parts by a pin. The outer peripheral surface of the rolling part is provided with an inwardly recessed V-shaped groove, and the end of the wire rope is sleeved in the V-shaped groove.

[0011] Furthermore, the first top block and the second top block are respectively fixedly equipped with opposing second top heads, and the two ends of the top rod are respectively provided with second spherical grooves that cooperate with the two second top heads, and the second top heads are rotatably disposed in the second spherical grooves.

[0012] Furthermore, it also includes a fixed mounting base, which is assembled from four mounting plates. The linear drive mechanism is fixedly mounted on the side of the mounting base away from the comb assembly. The first top block is located on the side of the mounting base near the comb assembly and is fixedly connected to a guide rod. The guide rod is set parallel to the driving direction of the linear drive mechanism and is slidably inserted into the mounting base.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] (1) This utility model adopts an electric cylinder, pneumatic cylinder or hydraulic cylinder as the actuator to replace the traditional servo motor and ball screw pair. The overall layout is redesigned, the structure is simplified, the number of parts is reduced, the cost is reduced, the appearance is more compact, the applicable models are more extensive, no complicated assembly is required, and the assembly and debugging are more convenient.

[0015] (2) This utility model optimizes the connection between the tensioning component and the output end of the linear drive mechanism into a rotational fit, avoiding interference with the transmission of the top rod and improving the flexibility and accuracy of the comb component during lateral translation.

[0016] (3) This utility model achieves a rotating connection through the cooperation of a spherical groove and a top head. The structure is simple, and a steel wire rope that is elastically connected to the pull tube replaces the traditional tension spring structure. This not only achieves the tensioning function, but also provides better support and is less prone to deformation and failure.

[0017] (4) This utility model achieves elastic connection between steel wire rope and pull tube through pre-compressed spring, and is equipped with pull rod to provide support and guidance for spring, which is not easy to deform and extends service life.

It is also applicable to comb assemblies with axial positional deviations from the output end of the linear drive mechanism.

[0019] (6) This utility model further improves the stability of left and right translational motion by adding a guide rod. Attached Figure Description

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] (Example 1)

[0028] like Figures 1 to 3 The warp knitting machine lateral movement device shown includes a guide bar assembly 1, a linear drive mechanism 2, a top rod 3, and a tensioning assembly 4. The top rod 3 and the tensioning assembly 4 are arranged in parallel and are both located between the guide bar assembly 1 and the linear drive mechanism 2. The two ends of the top rod 3 are respectively rotatably engaged with the output end of the linear drive mechanism 2 and the guide bar assembly 1, and are kept in close contact with the guide bar assembly 1 and the linear drive mechanism 2 by the tensioning assembly 4. The linear drive mechanism 2 directly drives the top rod 3, causing the guide bar assembly 1 to move left and right in the horizontal direction. The linear drive mechanism 2 uses an electric cylinder, pneumatic cylinder, or hydraulic cylinder to replace the traditional servo motor and ball screw pair. The overall layout is redesigned, simplifying the structure, reducing the number of parts, lowering costs, and making it more compact and applicable to a wider range of machine models. It eliminates the need for complex assembly, and assembly and debugging are also more convenient.

[0029] Specifically, this embodiment features a mounting base assembled from four mounting plates. The linear drive mechanism 2 uses an electric cylinder, which simplifies the structure and facilitates precise control. The electric cylinder is fixedly mounted on the side of the mounting base away from the comb assembly. The output end of the electric cylinder is fixedly connected to a first top block 5. The first top block is located on the side of the mounting base closer to the comb assembly and is fixedly connected to a guide rod. The guide rod is set parallel to the driving direction of the electric cylinder and slidably inserted into the mounting base.

[0030] A second top block 6 is fixedly mounted on the comb assembly 1. A first top head 7 and a hook 8 are respectively fixedly mounted on the second top block 6 and the first top block 5. The tensioning assembly 4 includes a wire rope 4-1, a pull tube 4-2, a pull rod 4-3, and a spring 4-4. The left end of the wire rope 4-1 is sleeved on the hook 8, and the right end is connected to the pull rod 4-3. The end of the pull rod 4-3 is provided with a connecting part 4-3-2 that is arranged opposite to each other. A rolling part 4-5 is rotatably connected between the two connecting parts 4-3-2 by a pin. The outer circumferential surface of the rolling part 4-5 is provided with an inwardly recessed V-shaped annular groove 4-5-1. The end of the wire rope 4-1 is sleeved in the V-shaped annular groove 4-5-1. A pull rod 4-3 is inserted into a pull tube 4-2, and a limiting nut 4-3-1 is fixedly installed at its right end to form a limiting part. A spring 4-4 ​​is sleeved on the pull rod 4-3, and its two ends abut against the left end of the pull tube 4-2 and the limiting nut 4-3-1, respectively, thereby realizing the elastic connection between the wire rope 4-1 and the pull tube 4-2. The right end of the pull tube 4-2 is provided with a first spherical groove that matches the first top head 7. The first top head 7 is rotatably disposed in the first spherical groove to realize a rotatable connection. The first top block 5 and the second top block 6 are respectively fixedly provided with opposing second top heads 9. The two ends of the push rod 3 are respectively provided with second spherical grooves that mate with the two second top heads 9. The second top heads are rotatably disposed in the second spherical grooves to realize the rotatable engagement between the push rod and the first top block 5 and the second top block 6.

[0031] This embodiment replaces the traditional servo motor and ball screw pair with an actuator in the form of an electric cylinder, pneumatic cylinder, or hydraulic cylinder. The overall layout is redesigned, simplifying the structure, reducing the number of parts, lowering costs, and resulting in a more compact size and wider applicability to various models. It eliminates the need for complex assembly, making assembly and debugging more convenient. Rotational engagement is achieved through the spherical contact between the push rod 3 and the push head, reducing the positional accuracy requirements of the comb assembly 1 and the electric cylinder's output end. This also applies to comb assemblies with axial positional deviations from the output end of the linear drive mechanism 2. Simultaneously, the connection between the tensioning assembly 4 and the output end of the linear drive mechanism 2 is optimized into a rotational engagement, achieved through the spherical groove and the push head. This simple structure avoids interference with the transmission of the push rod 3, improving the flexibility and accuracy of the comb assembly 1 during lateral translation. Furthermore, a steel wire rope elastically connected to the pull tube 4-2 replaces the traditional tension spring structure, achieving the tensioning function while providing better support and reducing the risk of deformation and failure.

It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
