Technical Field

[0001] The utility model relates to the technical field of texturing machines, in particular to a doffing, drawing and sucking structure of a texturing machine. Background Art

[0002] A texturing machine is a textile machine mainly used to deform untwisted yarns such as polyester and polypropylene through false twisting to produce stretch yarns with medium elasticity and low elasticity. These stretch yarns are widely used in clothing, home textiles and industrial fields. In the processing and production of stretch yarns, after completing the winding of a set of yarn bobbins, a wire cutter is needed to cut the wire to be wound, and a wire aspirator is used to assist in safely removing the wire from the machine so that the yarn bobbins can be replaced. This process needs to ensure that the wire will not be damaged or entangled, so as not to affect production efficiency and wire quality.

[0003] In the existing wire drawing and suction structure of the barrel of a texturizing machine, its power component is generally driven by a cylinder. By using a swing cylinder to control the swing of the wire drawing rod and the double-ear wire collecting hook, although the cylinder drive can realize the use function of the device, it has disadvantages such as high debugging difficulty, poor equipment compatibility, and easy breakage of the wire during mechanism operation, which affects the production efficiency of the product and cannot adapt to the switching use of multiple wires. Utility Model Content

By using a servo motor as a power device, after completing the winding of the wires on a group of wire drums, the servo motor on the bottom plate of the shell drives the left and right wire gathering hooks to hook the wires on both sides, and the servo motor on the top of the shell drives the wire drawing rod and the double-ear wire gathering hook to gather the wires to the opening of the wire cutter. While cutting the wires, the ends of the wires are sucked into the wire suction device, which can effectively improve the wire gathering success rate of the equipment, reduce the difficulty of debugging the equipment, and realize switching of multiple wires by adjusting the motor configuration of the corresponding wires.

[0005] The utility model is achieved through the following technical solutions:

[0006] A wire drawing and suction structure for a texturizing machine includes a shell and a bracket. One side of the shell is open. The bracket is fixedly connected to the edge of the top of the shell bottom plate near the opening. The side of the bracket facing the opening is horizontally connected to a wire sucker and a wire cutter. Two servo motors are fixedly connected to the top of the shell directly above the bracket and the top of the shell bottom plate behind the bracket respectively. The output end of the servo motor at the bottom passes through the shell. The output end of the servo motor at the top of the shell is respectively connected to a wire drawing rod and a double-ear wire gathering hook. The output end of the servo motor at the top of the shell bottom plate is connected to the wire gathering hook.

[0007] Furthermore, the wire cutter includes a U-shaped groove, two cylinders, an upper transmission plate, a lower transmission plate, an upper wire cutter and a lower wire cutter.

[0008] Furthermore, the U-shaped groove opening is opposite to the shell opening, the upper and lower plates of the U-shaped groove are provided with triangular openings, the cylinder is fixedly connected to the bottom plate connected to the back side of the U-shaped groove, the upper transmission plate, the upper wire cutter and the lower transmission plate, and the lower wire cutter are respectively hinged to the bottom surfaces of the upper and lower plates of the U-shaped groove.

One end of the upper wire cutter and the lower wire cutter is slidably connected to the slide groove, and the other end is a blade, which matches the opening shape of the upper and lower plates of the U-shaped groove.

[0010] Furthermore, the silk aspirator includes a vacuum generator, an air inlet pipe, a waste silk straight-through pipe, a vacuum tube, and a suction nozzle.

[0011] Furthermore, the air inlet pipe is connected to the air inlet of the vacuum generator, the waste silk straight-through pipe is connected to the air outlet of the vacuum generator, the vacuum tube is connected to the suction port of the vacuum generator, and the suction nozzle is connected to the other end of the vacuum tube, and the suction nozzle is directly opposite the middle of the openings of the upper and lower plates of the U-shaped groove.

[0012] Furthermore, when the screw-pulling rod is rotated to a position perpendicular to the opening surface of the shell, it is located directly above the openings of the upper and lower plates of the U-shaped groove.

[0013] Furthermore, the double-ear wire collecting hook includes two vertically parallel wire collecting arms, which are hinged to the upper and lower sides of the bracket. The spacing between the wire collecting arms is greater than the width of the wire cutter. A limiting groove is provided at the inner bend of the wire collecting arm. The distance from the limiting groove to the hinge axis is equal to the distance from the hinge axis to the openings of the upper and lower plates of the U-shaped groove.

The utility model uses a servo motor to replace the swing cylinder as the power device to drive the wire hook to hold the wires on both sides, and the wire drawing rod and the double-ear wire hook gather the wires to the opening of the wire cutter, which reduces the difficulty of debugging the equipment. By adjusting the working torque and rotation speed of the motor of the corresponding wire, it can also realize the switching of multiple wires, thereby expanding the scope of application.

[0018] 3. Since the utility model is equipped with an air inlet pipe and a waste silk straight-through pipe on the silk aspirator, when the silk aspirator is in operation, compressed air enters the vacuum generator from the air inlet pipe, forming a vacuum in the vacuum generator, so that external air is sucked into the vacuum tube from the suction nozzle, and the cut silk thread is sucked into the suction nozzle and discharged from the waste silk straight-through pipe. The size of the fluid cavity of the silk aspirator is expanded, and the suction force generated is larger and more stable, ensuring that the silk thread will not be damaged or entangled when being sucked into the silk aspirator, thereby improving production efficiency.
