[0002] CN203049201U discloses a warp feeding mechanism for a multi-comb Raschel warp knitting machine, including a yarn storage mechanism, a warp tension adjustment mechanism, a yarn separating needle, and a tension plate. The yarn storage mechanism consists of a warp frame and several warp bobbins mounted on the warp frame. The looping mechanism includes Jacquard combs. During operation, the warp yarns are unwound from the warp bobbins and sequentially pass through the yarn guide plate, two rollers, the yarn separating needle, and the tension plate to be fed to the Jacquard combs of the looping mechanism for weaving. The yarn frame in this application is fixed and only cooperates with the reciprocating transverse combs to feed yarn. However, the fabric woven by the reciprocating transverse combs has low strength. In order to improve the fabric strength, there is currently a circular rotating comb that can move along a circular track. In order to cooperate with it, it is urgent to develop a rotating yarn frame that moves synchronously with the rotating comb during its movement to ensure synchronous yarn feeding. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to solve the problem that the yarn frame in the prior art is fixed and can only cooperate with the reciprocating horizontal guide bar to supply yarn, but cannot cooperate with the annular rotating guide bar to ensure synchronous yarn supply, a rotating yarn frame for a warp knitting machine and the warp knitting machine thereof are provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a rotating yarn frame of a warp knitting machine, including an annular track, multiple yarn frames that rotate along the annular track, and a power mechanism for driving the yarn frames to move.

[0005] The power mechanism includes a rotary power source, a drive sprocket assembly that is connected to the rotary power source, and a driven sprocket assembly that cooperates with the drive sprocket assembly and is located in a circular track. A lifting device for quick assembly and disassembly of the yarn frame is provided between the driven sprocket assembly and the yarn frame.

[0006] Furthermore, it also includes a guide rail located at the bottom of the yarn frame for guiding the movement of the yarn frame, and rollers that cooperate with the guide rail are installed on the yarn frame.

[0007] Furthermore, the lifting device includes a lifting rod and a hook hinged to the lifting rod and used to engage with a lifting ring at the top of the yarn frame.

[0008] Furthermore, the middle part of the hook protrudes radially to form a limiting part, and a limiting ring is provided between the rod and the limiting part, with the rod and the limiting part confining the limiting ring between them.

[0009] Furthermore, the driven sprocket assembly includes staggered traveling wheels and guide wheels, with their axes perpendicular to each other.

[0010] Furthermore, the top of the boom is bent to form two arms, the tops of the two arms are fitted onto the axles of the traveling wheels, and the bottoms of the two arms are connected to pins for the hooks to be fitted onto.

[0011] Furthermore, the middle sections of the two arms bend away from each other.

[0012] Furthermore, the yarn frame is provided with a tensioner, a threading plate, and a take-up spring in sequence along the yarn direction.

[0013] Furthermore, it also includes a base and multiple columns for supporting the circular track and guide rails.

[0014] A warp knitting machine includes a rotating yarn frame as described above.

[0015] The beneficial effects of this utility model are: This utility model uses a rotary power source to drive the active sprocket group to rotate, and the driven sprocket group rotates synchronously. Through the hanger, it drives multiple yarn frames to rotate along the circular track, so that it can move synchronously with the circular rotating comb to feed yarn synchronously, thereby improving the stability of yarn feeding. In addition, the hanger can realize the quick assembly and disassembly of the yarn frame while reducing stress and increasing the service life of the rotating yarn frame.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components, orientations, and references (e.g., up, down, left, right, etc.) relevant to the present invention and are intended only to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be limiting, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0039] like Figure 1-11As shown, a rotating yarn frame of a warp knitting machine includes an annular track 1, multiple yarn frames 2 that rotate along the annular track 1, and a power mechanism 3 for driving the yarn frames 2 to move. The annular track 1 has an elongated oval structure and includes two straight segments and two arc segments.

[0040] The power mechanism 3 includes a rotary power source 301, a drive sprocket assembly 302 that is connected to the rotary power source 301, and a driven sprocket assembly 303 that cooperates with the drive sprocket assembly 302 and is located in the annular track 1. A lifting device 4 for quick assembly and disassembly of the yarn frame 2 is provided between the driven sprocket assembly 303 and the yarn frame 2. The lifting device 4 can realize quick assembly and disassembly of the yarn frame while reducing stress and increasing the service life of the rotary yarn frame.

[0041] The drive sprocket assembly 302 includes multiple chain links, a connecting block connecting two adjacent chain links, a drive wheel and a driven wheel that drive the chain links to move. The connecting block is provided with teeth for inserting into the driven sprocket assembly 303 to drive the driven sprocket assembly 303 to move synchronously. The top of the annular track 1 is provided with an upper slot for the drive sprocket assembly 302 to extend into, and the bottom is provided with a lower slot for the lifting device 4 to extend out.

[0042] The rotary power source 301 can be a servo motor. The servo motor is connected to the drive pulley via a chain assembly or a synchronous belt assembly to drive the drive sprocket assembly 302 to rotate. In this embodiment, it is a synchronous belt assembly, which includes a drive pulley 304 connected to the output end of the servo motor, a driven pulley 305, and a synchronous belt 306 wound around the drive pulley 304 and the driven pulley 305. The driven pulley 305 is coaxially fixed with the drive pulley of the drive sprocket assembly 302. The drive sprocket assembly 302 drives the driven sprocket assembly 303 to rotate synchronously. The driven sprocket assembly 303 drives multiple yarn frames 2 to rotate along the annular track 1 via the hanger 4, so that it can move synchronously with the annular rotating comb to perform synchronous yarn feeding and improve the stability of yarn feeding.

[0043] In some examples, a guide rail 5 located at the bottom of the yarn frame 2 is also included to guide the movement of the yarn frame 2. The yarn frame 2 is equipped with rollers 201 that cooperate with the guide rail 5. The rollers 201 are mounted on the yarn frame 2 by a bracket and roll along the guide rail 5. The guide rail 5 is also annular and has an angular cross-section. The yarn frame 2 extends longitudinally, the annular track 1 is located at the top of the yarn frame 2, and the guide rail 5 is located at the bottom of the yarn frame 2. The annular track 1 and the guide rail 5 are located at the two ends of the yarn frame 2 in the longitudinal direction, which can ensure that the yarn frame 2 rotates along the predetermined track and avoid the yarn frame 2 shaking due to excessive yarn tension.

[0044] In some examples, the lifting device 4 includes a lifting rod 401 and a hook 402 hinged to the lifting rod 401 and used to engage with a lifting ring 205 at the top of the yarn frame 2. The hook portion of the hook 402 passes through the lifting ring 205, and one end of the lifting device 4 away from the hook 402 is connected to the driven sprocket assembly 303.

[0045] In some examples, the middle part of the hook 402 protrudes radially to form a limiting part 403. A limiting ring 6 is provided between the rod 401 and the limiting part 403, and the rod 401 and the limiting part 403 limit the limiting ring 6 between them. The cross-section of the limiting part 403 can be circular, square, or other regular or irregular shapes. It only needs to satisfy the requirement of limiting the downward movement of the limiting ring 6. The limiting ring 6 is annular and has multiple through holes for the rod 401 to pass through. Multiple yarn frames 2 corresponding to the lifting devices 4 can be connected in series through the limiting ring 6 to reduce the sway caused by the lifting devices 4.

[0046] In some examples, the driven sprocket assembly 303 includes staggered traveling wheels 3031 and guide wheels 3032, with their axes perpendicular to each other. The axis of the traveling wheels 3031 extends horizontally, and the axis of the guide wheels 3032 extends vertically. The traveling wheels 3031 are arranged in pairs, and an axle connects the two traveling wheels 3031.

[0047] In some examples, the top of the boom 401 is bent to form two arms 4011, the tops of the two arms 4011 are fitted onto the axle of the traveling wheel 3031, forming a double-layer fit, which can improve the structural strength of the boom 401 and the axle. The bottom ends of the two arms 4011 are connected to pins 404 for the hook 402 to be fitted onto. The top of the hook 402 has a fitting part 405 for fitting onto the outside of the pins 404.

[0048] In some examples, the two booms 4011 are bent in the middle away from each other so that the bottom ends of the two booms 4011 expand to leave enough space for the installation of the sleeve portion 405 of the hook 402. The longer sleeve portion 405 can further improve the structural strength of the connection between the boom 401 and the hook 402.

[0049] In some examples, the yarn frame 2 is provided with a tensioner, a threading plate 203, and a take-up spring 204 in sequence along the yarn direction. The tensioner is mounted on the yarn frame 2 via a tensioner bracket 202. The threading plate 203 and the take-up spring 204 are mounted at the bottom of the yarn frame 2. The yarn is unwound from the yarn bobbin on the yarn frame 2, passes through the tensioner, and enters the threading plate 203. Then, the yarn exits from the threading plate 203 and enters the take-up spring 204, which is used to adjust the yarn tension.

[0050] In some examples, a base 7 and multiple columns 8 for supporting the annular track 1 and the guide rail 5 are also included. The multiple columns 8 include an inner column located inside the yarn frame 2 and an outer column located outside the yarn frame 2. The inner column 8 is used to support the guide rail 5, and the outer column is used to support the annular track 1 and the servo motor. The base 7 is also generally annular in structure.

[0051] In some examples, a warp knitting machine includes the aforementioned rotating yarn frame.
