Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a composite yarn guiding device for core-spun three-core yarn. Background Technology

[0002] As is well known, core-spun three-core yarn is widely used in the production of various textiles in the textile industry due to its unique properties. The yarn guiding device, as a key piece of equipment in the production process of core-spun three-core yarn, directly affects the quality of the yarn and production efficiency.

[0003] Currently, traditional yarn guiding devices have many shortcomings when producing core-spun three-core yarns. First, the yarn guiding mechanism of traditional devices has a fixed position and cannot be flexibly adjusted according to the production needs of different yarn specifications and the diverse layout of spinning equipment. As a result, when producing core-spun three-core yarns of different thicknesses, it is difficult for the three core yarns to maintain a proper relative position during the guiding process, which can easily lead to mutual interference and thus affect the yarn quality.

[0004] Secondly, traditional yarn guiding devices suffer from low precision in adjusting the guide wheel angle and are cumbersome to operate, failing to accurately meet the angle requirements of different yarn guiding paths. In some special core-spun yarn production processes, when the core yarn needs to enter the twisting area at a specific angle, traditional devices struggle to achieve precise angle control, resulting in uneven stress on the yarn during subsequent twisting processes. This reduces the structural stability and product quality of the core-spun yarn, thus necessitating solutions to these technical problems. Utility Model Content

[0023] 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.

[0024] Please see Figures 1-4This utility model relates to a composite yarn guiding device for core-spun three-core yarn, comprising a worktable 1, on which a yarn guiding mechanism is provided. The yarn guiding mechanism includes mounting boxes 2, of which two are provided. The first mounting box 2 is fixed to the top of the worktable 1, and the second mounting box 2 is provided with a sliding mechanism between itself and the worktable 1. A telescopic rod 3 is provided between the two mounting boxes 2. A mounting groove is provided at the top of the mounting box 2, and a heat dissipation hole 4 is provided between the mounting groove and the mounting box 2. A drive motor 5 is provided in the mounting groove, and a bearing seat 6 is provided at the top of the mounting groove. A turntable 7 is provided on the bearing seat 6. The output end of the drive motor 5 is connected to the turntable 7. An angle locking mechanism is provided between the mounting groove and the turntable 7. A yarn guiding wheel 8 is provided above the turntable 7, and both ends of the yarn guiding wheel 8 are connected to the turntable 7. The yarn guiding mechanism is connected by mounting base 9. There are three mounting boxes 2 in this embodiment. One is fixed to the top of the workbench 1, and the other is connected to the workbench 1 via a sliding mechanism, allowing one mounting box 2 to move flexibly. This allows the relative position between the two mounting boxes 2 to be adjusted according to the production needs of different yarns and the equipment layout. The relative position between the two mounting boxes 2 can be adjusted by controlling the telescopic rod 3. Inside the mounting box 2, a drive motor 5 is placed in the mounting slot at the top. The output end of the drive motor 5 is connected to a turntable 7 mounted on a bearing seat 6. The drive motor 5 rotates the turntable 7, and the turntable 7 rotates at a stable angle via the bearing seat 6. Above the turntable 7, a yarn guide wheel 8 is connected to the turntable 7 via mounting base 9. Thus, the rotation of the turntable 7 drives the yarn guide wheel 8 to rotate synchronously, guiding the yarn. Simultaneously, an angle locking mechanism is provided between the mounting slot and the turntable 7 to fix the turntable 7 at a specific angle, meeting the angle requirements of the yarn guide wheel 8 for different yarn guiding paths. In addition, the heat dissipation holes 4 are designed to ensure that the heat generated by the drive motor 5 during long-term operation can be dissipated in a timely manner, maintaining the motor's stable performance and service life. The entire yarn guiding mechanism has three sections, each corresponding to one of the three core yarns in a core-spun three-core yarn. It can guide all three core yarns simultaneously. The sliding design of the mounting box 2 allows the yarn guiding device to flexibly adapt to different yarn specifications and diverse spinning equipment layouts. For example, when producing core-spun three-core yarns of different thicknesses, the distance between the guide wheels 8 can be adjusted by sliding the mounting box 2 to ensure that the three core yarns maintain a suitable relative position during the guiding process, avoiding mutual interference between yarns and improving yarn quality. The drive motor 5 drives the turntable 7 and the guide wheels 8 to rotate. With the help of the angle locking mechanism, the operator can precisely set the guiding angle of the guide wheels 8 according to the requirements of the actual production process. This precise angle control allows the yarn to be guided along a specific path, which is beneficial for ensuring uniform stress on the yarn in subsequent twisting and other processes, improving the structural stability and product quality of the core-spun yarn.For example, in certain specialized core-spun yarn production processes, the core yarn may need to enter the twisting area at a specific angle. In such cases, the device's controllable yarn guide angle function plays a crucial role. By setting up three yarn guide mechanisms, the three core yarns of a three-core core-spun yarn can be guided simultaneously, ensuring consistency and coordination during the guiding process. This helps improve the production quality and efficiency of core-spun yarn. Compared to devices that guide the core yarns one by one, this significantly saves production time and increases production efficiency.

[0025] To improve the linear movement stability of the mounting box 2, in this design, the sliding mechanism includes a slide rail 10 and a slide groove. The slide rail 10 is installed at the top of the worktable 1, and the slide groove is located at the bottom of the second mounting box 2. The slide rail 10 passes through the slide groove. Both the slide rail 10 and the slide groove have a T-shaped structure. The T-shaped structure design prevents the mounting box 2 from detaching from the slide rail 10 during sliding, ensuring the stability and reliability of the sliding of the mounting box 2. The second mounting box 2 can slide smoothly along the slide rail 10 at the top of the worktable 1, allowing adjustment of the distance between it and the fixed mounting box 2.

[0026] To further improve the linear movement stability of the mounting box 2, this design includes two symmetrically arranged sliding mechanisms. These symmetrical mechanisms significantly enhance the smoothness of the mounting box 2 during sliding. When adjusting the position of the mounting box 2, the sliding mechanisms on both sides can evenly distribute the weight of the mounting box 2, preventing excessive force on one side and thus preventing the mounting box 2 from tilting or wobbling during sliding.

[0027] To facilitate flexible locking of the iron ring 11's angle, in this design, the angle locking mechanism includes an iron ring 11 and an electromagnet 12. The electromagnet 12 is installed on the inner wall of the mounting groove, and the iron ring 11 is installed at the bottom of the turntable 7 and abuts against the top of the electromagnet 12. When the electromagnet 12 is energized, it generates magnetism, attracting the iron ring 11 and thus firmly fixing the turntable 7 in its current position, achieving angle locking. When it is necessary to adjust the angle of the turntable 7, the power supply to the electromagnet 12 is cut off, the iron ring 11 loses its magnetic attraction, and the turntable 7 can then rotate freely under the drive of the drive motor 5. After reaching the desired angle, the drive motor 5 is turned off and energized again to lock the turntable. The electromagnetic locking method is more precise and can fix the turntable 7 at any desired angle with minimal error.

[0028] To precisely adjust the distance between the two mounting boxes 2, in this design, the telescopic rod 3 is an electric push rod. The electric push rod is driven by a motor to rotate a screw, converting the motor's rotational motion into the push rod's linear motion, thereby adjusting the distance between the two mounting boxes 2. The electric push rod's extension and retraction lengths can be precisely controlled by a control system, thus precisely controlling the spacing between the two mounting boxes 2.

[0029] To improve the angular accuracy of the control turntable 7, in this design, the drive motor 5 is a servo motor, which can precisely control the rotation speed and angle. The control system can send precise control signals to the servo motor, and the motor adjusts the output shaft's speed and angle precisely according to the signals, thereby accurately controlling the rotation speed and angle of the turntable 7 and the guide wheel 8.

[0030] To prevent yarn deviation on the guide roller 8, this design incorporates annular grooves 13 on the guide roller 8. These grooves effectively restrict the yarn's position on the guide roller 8, ensuring that the yarn always travels along a predetermined path during the guiding process. This avoids problems such as mutual interference or friction with other components caused by yarn deviation. This is crucial for improving yarn production quality, reducing yarn breakage rates, and increasing production efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
