Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and in particular to a textile twisting machine. Background Technology

[0002] The textile twisting machine is a key piece of equipment in the textile industry used to twist yarn. Through its efficient working principle of "one turn, two twists", it can significantly improve the production efficiency and twisting quality of yarn and is widely used in the production of various high-quality yarns.

[0003] Maintaining constant and appropriate yarn tension is one of the core factors determining the quality of the final yarn during the high-speed twisting process of a doubling machine. Excessive yarn tension can easily lead to yarn breakage or fiber damage; while insufficient tension will result in uneven twist, loose yarn, and poorly structured yarn packages. Therefore, effectively controlling yarn tension is a crucial technical aspect that must be addressed in the design of a doubling machine.

[0004] Currently, existing doubling machines typically employ passive tension devices, such as spring sheets, magnetic components, or gravity blocks, to apply a relatively fixed pressure to the yarn. However, the adjustment methods of these devices are often rather coarse, making it difficult to achieve precise and quantitative adjustments. When it is necessary to change to different yarn counts or materials, or to change the tension value according to process requirements, operators often need to stop the machine for tedious, experience-based adjustments. This not only reduces production efficiency but also fails to guarantee the accuracy and consistency of each adjustment.

[0005] As the textile market continues to demand higher yarn quality, the current technical limitations of not being able to perform convenient and precise tension adjustment have become a bottleneck restricting the further improvement of product quality and adaptation of doubling machines to multi-variety, small-batch production models.

[0006] Therefore, this utility model proposes a textile twisting machine to overcome the shortcomings of the prior art. Utility Model Content

[0007] To overcome the above shortcomings, this utility model provides a textile twisting machine, which aims to improve the problems of inconvenient yarn tension adjustment, low precision, and difficulty in adapting to different process requirements in the existing textile twisting machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a textile twisting machine, comprising: a twisting machine body, a twisting drum rotatably mounted on the twisting machine body; and a guiding mechanism.

[0009] The guiding mechanism includes a guide mounting rod fixedly connected to the body of the twisting machine, and an adjusting screw threaded onto the guide mounting rod. The guiding mechanism also includes a slider, a compression adjusting plate, a disc spring, and a guide roller.

[0010] The slider is slidably connected along the axial direction of the guide mounting rod. One end of the slider is driven by the rotation of the adjusting screw to generate axial displacement. The other end of the slider is fixedly connected to the extrusion adjusting plate. The disc spring is provided between the extrusion adjusting plate and the bearing seat of the guide roller. Through this combination, the rotational motion of the adjusting screw is converted into precise adjustment of the pressure of the guide roller.

[0011] The above technical solution enables precise control of yarn tension, ensuring stable yarn tension during the guiding process and reducing the effects of fuzzing or breakage caused by tension fluctuations.

[0012] Preferably, it further includes a rotating transmission plate, which is connected to the bottom of the twisting drum to drive the twisting drum to rotate.

[0013] The above technical solution enables high-speed and stable rotation of the twisting drum, providing reliable rotation conditions for the yarn twisting process and ensuring uniform twisting quality.

[0014] Preferably, it also includes an airflow compensation ring, which is arranged around the outer periphery of the twisting drum to stabilize the yarn.

[0015] The above technical solution achieves stable tension in the yarn twisting area, avoids the impact of sudden tension changes on twist consistency, and improves the yarn twisting quality.

[0016] Preferably, it further includes a wire guide roller and a winding drum rotatably connected above the body of the twisting machine, and the guiding mechanism is located between the twisting drum and the wire guide roller.

[0017] The above technical solution achieves orderly guidance, uniform yarn arrangement and stable winding of twisted yarn, ensuring that the finished yarn package is tight and neatly arranged, which facilitates subsequent use.

[0018] Preferably, it further includes a pressing assembly, wherein the pressing ring plate of the pressing assembly can elastically abut against the surface of the winding cylinder under the elastic force of the compression spring, pressing the winding cylinder against the wire guide roller.

[0019] The above technical solution achieves stable contact between the winding bobbin and the yarn guide roller during the winding process, avoiding yarn arrangement disorder caused by the winding bobbin slipping and ensuring the winding effect.

[0020] Preferably, the compression spring and a portion of the compression ring plate of the clamping assembly are housed in a mounting groove provided on the transverse support plate.

[0021] The above technical solution achieves the orderly storage of internal components of the clamping assembly, reduces the space occupied by the components, and avoids the components from being exposed to external interference, thereby improving the compactness and stability of the structure.

[0022] Preferably, it also includes an electrical controller, which is electrically connected to a power device for driving the twisting drum and the winding roller.

[0023] The above technical solution enables centralized control and parameter adjustment of the core operating components of the equipment, allowing for flexible adjustment of process parameters such as rotation speed, and facilitating real-time monitoring of the operating status, thereby improving operational convenience and equipment controllability.

[0024] Preferably, the guide roller is made of ceramic material.

[0025] The above technical solution reduces frictional loss between the yarn and the guide roller, reduces yarn fuzz, extends the service life of the guide roller, and ensures long-term guiding stability.

[0026] This utility model has the following beneficial effects: 1.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 6 The present invention provides an embodiment of a textile twisting machine, which aims to solve the problem that existing textile twisting machines are unable to accurately and dynamically adjust yarn tension, resulting in tension fluctuations affecting the twisting quality.

[0032] The textile twisting machine includes a twisting machine body 1 as an overall support frame, and a twisting drum 2 rotatably mounted on the twisting machine body 1. The twisting drum 2 is driven to rotate by a rotating transmission plate 7 connected to the bottom of the twisting drum 2 to realize the twisting operation of the yarn. The guide mechanism 8 is set on the yarn lead-out path of the twisting drum 2 and is used to precisely adjust the yarn tension. The guide mechanism 8 includes a guide mounting rod 801 fixedly connected to the body 1 of the twisting machine. The guide mounting rod 801 provides a stable mounting base for the entire guide mechanism 8. The adjusting screw 802 is threadedly engaged with the guide mounting rod 801. By rotating the adjusting screw 802, precise position adjustment can be achieved. The slider 803 is slidably connected to the guide mounting rod 801 along the axial direction of the guide mounting rod 801. One end of the slider 803 is directly driven by the rotation of the adjusting screw 802, thereby converting the rotational motion of the adjusting screw 802 into the precise axial displacement of the slider 803 itself. The other end of the slider 803 is fixedly connected to the extrusion adjustment plate 804, so that the extrusion adjustment plate 804 can move axially synchronously with the slider 803; a guide roller 806 is rotatably provided in front of the extrusion adjustment plate 804, and the yarn passes around the surface of the guide roller 806. A disc spring 805, serving as an elastic buffer and pressure transmission component, is provided between the bearing seat of the compression adjusting plate 804 and the guide roller 806. By rotating the adjusting screw 802, the slider 803 and the compression adjusting plate 804 are moved, thereby changing the degree of compression of the disc spring 805 by the compression adjusting plate 804. The disc spring 805 then applies the precisely adjusted elastic pressure to the guide roller 806, ultimately achieving precise control of the yarn tension passing through the guide roller 806.

[0033] Driven by the transmission mechanism, the yarn guide roller 5 not only rotates itself, but also reciprocates along the transverse direction of the twisting machine body 1. The reciprocating motion of the yarn guide roller 5 is used to guide the yarn to be evenly arranged on the winding bobbin 3. The winding bobbin 3 is rotatably connected to the top of the twisting machine body 1 and is used to wind up and store the twisted yarn. In order to ensure that the winding bobbin 3 forms a stable and reliable frictional transmission with the winding roller 5 during the winding process, the textile twisting machine also includes a pressing assembly 9. The pressing assembly 9 includes a pressing ring plate 905 elastically connected to the compression spring 904. The pressing ring plate 905 can elastically abut against the surface of the winding bobbin 3 and press the winding bobbin 3 against the lower winding roller 5 by applying continuous pressure. Specifically, the clamping assembly 9 also includes a longitudinal support plate 901 and a transverse support plate 902 as the mounting base. A portion of the compression spring 904 and the clamping ring plate 905 are housed in a mounting groove 903 opened on the transverse support plate 902, making the structure of the clamping assembly 9 more compact, while providing stable and reliable guidance and limiting for the elastic movement of the clamping ring plate 905. In addition, to compensate for the sudden change in yarn tension caused by the high-speed rotation of the twisting drum 2, the textile twisting machine is also equipped with an airflow compensation ring 6. The airflow compensation ring 6 is arranged around the outer periphery of the twisting drum 2 and compensates for the yarn tension by outputting airflow, thereby further improving the twisting quality of the yarn. In order to improve the wear resistance and reduce friction damage when the yarn passes through, the guide roller 806 in the guide mechanism 8 is preferably made of ceramic material. The ceramic material has a smooth surface and high hardness, which can effectively reduce the fuzz generated by the yarn during high-speed movement and ensure the quality of the yarn. In order to achieve comprehensive monitoring and precise control of the equipment's operating status, the textile twisting machine also includes an electrical controller 4. The electrical controller 4 is electrically connected to the power unit used to drive the twisting drum 2 and the winding roller 5. Through preset programs or operating instructions, it coordinates the rotation speed of the twisting drum 2, the winding speed of the winding roller 5, and the operating parameters of other related components.

[0034] Working principle: In the process of using this textile twisting machine, the raw yarn to be twisted is first installed on the twisting drum 2. The raw yarn is guided into the twisting drum 2 by the guide roller 806 of the guide mechanism 8. The twisting drum 2 is rotatably connected to the rotating transmission plate 7 and rotates at high speed under the drive of the rotating transmission plate 7, so that the raw yarn completes the twisting action in the twisting drum 2. At the same time, the airflow compensation ring 6 is arranged around the outer circumference of the twisting drum 2. By outputting a small airflow, it balances the tension fluctuation of the yarn during the twisting process and improves the twisting uniformity. The twisted yarn is guided again by the guide mechanism 8 and enters the winding roller 5. The winding roller 5 rotates... The reciprocating motion of the winding bobbin 3, connected to the body 1 of the twisting machine, evenly distributes the yarn onto the winding bobbin 3. The winding bobbin 3 is rotatably connected to the top of the body 1 of the twisting machine to realize the winding and storage of the finished yarn. Throughout the process, the electrical controller 4 is electrically connected to each component to control the operating parameters of the equipment, such as speed and tension. The longitudinal support plate 901 and the transverse support plate 902 of the pressing assembly 9 are fixedly connected. The transverse support plate 902 is elastically connected to the pressing ring plate 905 through the shrinkage spring 904 set in the mounting groove 903 to elastically press the winding bobbin 3 to ensure the stability of the bobbin during the winding process. In actual operation, the raw yarn is drawn out from the twisting drum 2 and enters the guiding mechanism 8. The guide mounting rod 801 is fixed on the body 1 of the doubling machine. The adjusting screw 802 is threadedly connected to the guide mounting rod 801. By rotating the adjusting screw 802, the compression adjusting plate 804 can be moved, thereby compressing the disc spring 805 and adjusting the pressure of the guide roller 806 on the yarn to achieve the adjustment of yarn tension. The yarn laying roller 5 rotates under the drive of the transmission mechanism, and in conjunction with the rotation of the winding bobbin 3, the yarn is evenly arranged. The winding bobbin 3 is pressed... Under the elastic pressing action of component 9, it always maintains a suitable contact with the yarn guide roller 5 to ensure the tightness of the winding. The high-speed rotation of the twisting drum 2 is powered by the rotating transmission plate 7. The rotating transmission plate 7 is connected to the drive component in the body 1 of the twisting machine to ensure the stable speed of the twisting drum 2 and provide reliable power for yarn twisting. The airflow compensation ring 6 continuously outputs airflow to compensate the tension of the yarn in the area of ​​the twisting drum 2, avoids sudden changes in yarn tension caused by the high-speed rotation of the twisting drum 2, and further improves the twisting quality of the yarn. In this textile twisting machine, the twisting drum 2 is made of high-strength alloy material to ensure structural strength and dynamic balance performance during high-speed rotation. The guide roller 806 is made of ceramic material to reduce yarn friction and reduce fuzz generation. The yarn guide roller 5 is made of carbon fiber composite material to reduce transmission inertia and improve operating efficiency. The rotating transmission plate 7 is equipped with a belt and gear transmission structure. Its main motor is a high-efficiency and energy-saving permanent magnet synchronous motor, which is matched with a frequency converter to achieve stepless speed regulation function, providing power to the twisting drum 2 and ensuring its high-speed and stable rotation.
