Description

Technical Field

[0001] The utility model relates to a yarn doubling device, in particular to a low-pressure yarn doubling machine. Background Art

[0002] Yarns are typically formed into extremely fine fiber strands using forming equipment, and then joined together into thicker fiber strands using a doubling machine. When doubling extremely fine fiber strands, a netting machine is often used to purge multiple strands of fiber to achieve winding and doubling. Because traditional doubling machines only have a traction device behind the netting machine, the fiber strands passing through the netting machine have excessive tension. To ensure smooth doubling, the netting machine's purge air pressure must be increased, resulting in high air consumption and the extremely fine fibers being easily broken. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a low-pressure yarn doubling machine.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a low-pressure yarn doubling machine, including a frame, a take-up assembly arranged on the frame, a network device arranged on the frame, and also including a first traction assembly and a second traction assembly, the network device is located between the first traction assembly and the second traction assembly, the first traction assembly and the second traction assembly have the same structure, the first traction assembly includes a traction roller, an auxiliary roller arranged parallel to the traction roller, and a traction motor driven by the traction roller, and a tension rod is provided on the frame.

[0005] As a further improvement of the present design, the wire take-up assembly includes a switching turntable, take-up shafts distributed in a circular array around the rotation axis of the switching turntable, and a wire arranger located on a peripheral frame of the switching turntable.

[0006] As a further improvement of the present design, a traction guide wheel is provided on the frame between the network device and the second traction assembly, a line feed guide wheel frame is provided on the frame, and a plurality of line feed wheel bodies are provided on the line feed guide wheel frame.

[0007] As a further improvement of the present design, the tension rod is arranged below between the winding assembly and the second traction assembly, and the height of the tension rod is lower than the height of the winding assembly.

[0008] The beneficial effect of the present invention is that the surface tension of the fiber line passing through the network device is reduced by arranging the network device between the first traction component and the second traction component. The network device only needs a small air pressure to make the fiber lines entangle and fold, effectively reducing the air supply and reducing the blow-off of the fiber lines.

DETAILED DESCRIPTION

[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The exemplary embodiments and descriptions are only used to explain the present invention but are not intended to limit the present invention.

[0014] Example: See Figure 1 This embodiment provides a low-pressure yarn doubling machine, including a frame 1, a take-up assembly 7 arranged on the frame 1, a network device 4 arranged on the frame 1, and also including a first traction assembly 2 and a second traction assembly 6. The network device 4 is located between the first traction assembly 2 and the second traction assembly 6. The first traction assembly 2 and the second traction assembly 6 have the same structure. The first traction assembly 2 includes a traction roller 21, an auxiliary roller 22 arranged parallel to the traction roller 21, and a traction motor 20 driven and connected to the traction roller 21. A tension rod 8 is provided on the frame 1, and the network device 4 is a commonly used commercially available part.

[0015] By setting the network device between the first traction component and the second traction component, the surface tension of the fiber line passing through the network device is reduced. The network device only needs a small air pressure to make the fiber line entangle and fold, effectively reducing the air supply and reducing the breakage of the fiber line.

[0016] See Figure 2 The take-up assembly 7 includes a switching turntable 70, winding shafts 71 arranged in a circular array around the rotation axis of the switching turntable 70, and a wire arrangement device 72 located on the frame 1 outside the switching turntable 70. The switching turntable is used to simultaneously unload the fully wound fiber drum while winding, thereby improving production efficiency.

[0017] See Figure 1A traction guide wheel 5 is provided on the frame 1 between the network device 4 and the second traction assembly 6 to facilitate the arrangement of the second traction assembly. A line feed guide wheel frame 3 is provided on the frame 1, and a plurality of line feed wheel bodies 9 are provided on the line feed guide wheel frame 3 to facilitate the introduction of the fiber line into the first traction assembly.

[0018] See Figure 1 The tension rod 8 is arranged below the wire-taking assembly 7 and the second traction assembly 6. The height of the tension rod 8 is lower than that of the wire-taking assembly 7, which is convenient for controlling the tension during winding and improving the winding quality.

[0019] During operation, the fiber line passes through the feed pulley 9, the first traction assembly 2, the network device 4, the traction guide wheel 5, the second traction assembly 6, and the tension rod 8, before being wound onto the take-up shaft 71. The cable arrangement device 72 cooperates with the take-up shaft 71 to wind the paralleled fiber line onto the take-up shaft 71. When one take-up shaft 71 has finished winding, the switch dial 70 rotates to move the other take-up shaft 71 to the winding position, and the worker removes the fully wound fiber line from the take-up shaft 71.

[0020] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
