Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a core-spun yarn spinning device with adjustable coating thickness. Background Technology

[0002] Core-spun yarn, an important material in the textile industry, is made by spinning a core yarn (such as spandex or polyester filament) together with an outer fiber (such as cotton or wool). The thickness of the outer layer directly affects the elasticity, strength, and comfort of the fabric, and it is widely used in clothing, home textiles, and other fields.

[0003] In existing technologies, core-spun yarn spinning devices typically employ fixed yarn guide structures or simple mechanical adjustment mechanisms to adjust the coating thickness. However, these methods suffer from several significant drawbacks: First, the adjustment precision of the coating thickness is low, failing to meet the diverse needs of different specifications of outer fibers (such as fine denier and coarse denier fibers). Second, the fixed diameter of the yarn guide holes necessitates frequent replacement of the yarn guide components to accommodate different outer fibers, leading to reduced production efficiency. Third, the lack of a real-time tension monitoring and feedback mechanism makes the coating uneven due to yarn tension fluctuations, affecting product quality. Therefore, there is an urgent need for a core-spun yarn spinning device with optimized structure, precise adjustment, and strong adaptability. Utility Model Content

[0004] The purpose of this invention is to provide a core-spun yarn spinning device with adjustable coating thickness. Through modular structural design, replaceable yarn guide components and intelligent tension monitoring, the device can achieve precise adjustment of coating thickness and improve its adaptability to different specifications of outer fibers.

[0005] The present invention provides a spinning device for core-spun yarn with adjustable covering thickness, comprising a yarn supply mechanism and a thickness adjustment mechanism. The thickness adjustment mechanism includes a fixed frame, a movable yarn guide frame, a yarn guide, and a drive unit. The fixed frame is a frame structure, which is composed of fixed plates at both ends and multiple connecting rods in the middle. One end of the fixed plate is sleeved on the yarn outlet end of the yarn supply mechanism, and the multiple connecting rods are located at the four corners of the fixed plate. The movable yarn guide frame is slidably connected to the connecting rods, and the yarn guide is fixed in the middle position of the movable yarn guide frame. The drive unit is located on one side of the fixed frame, and the drive unit is slidably connected to a drive plate. One side of the drive plate is fixedly connected to the movable yarn guide frame.

[0006] In a preferred embodiment of this invention, the yarn guide has a yarn guide hole in the center, and the yarn guide hole is a replaceable ceramic eyelet. The yarn guide hole is concentrically arranged with the yarn outlet end of the yarn supply mechanism. The yarn guide hole of the yarn guide has different aperture specifications to accommodate outer fibers of different fineness.

[0007] As a preferred technical solution of this utility model, a tension detector is provided at the connection between the movable yarn guide frame and the yarn guide, and the tension detector is arranged in a ring at equal intervals on the outside of the yarn guide.

[0008] As a preferred technical solution of this utility model, the top side of the movable yarn guide frame is provided with a positioning groove at the connecting rod, and the connecting rod at the positioning groove is provided with a corresponding position scale.

[0009] As a preferred technical solution of this utility model, the two ends of the drive unit are extension plates set on one side of the fixed frame, and a guide rod and a precision lead screw parallel to the connecting rod are set between the two extension plates. The precision lead screw is driven to rotate by a stepper motor.

[0010] In a preferred embodiment of this invention, the drive plate is connected to the precision lead screw via a thread and is slidably connected to the guide rod.

[0011] As a preferred embodiment of this invention, the drive unit is connected to a controller for setting and controlling the moving position of the movable yarn guide frame.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. Precise adjustment of covering thickness: Through the transmission structure of precision lead screw and guide rod, combined with stepper motor drive, the linear and precise displacement of the moving yarn guide frame is realized. Combined with the controller setting parameters, the covering thickness error can be controlled within ±0.1mm.

[0014] 2. Strong adaptability: The yarn guide adopts a replaceable ceramic eye mold design, which supports quick switching of multiple aperture specifications and is suitable for outer fibers of different fineness (such as 10D-100D). There is no need to replace the entire yarn guide component, thus improving production efficiency.

[0015] 3. Real-time tension monitoring: The ring-shaped stress plate tension detector monitors the yarn tension in real time and feeds it back to the control system through a signal converter to dynamically adjust the position of the moving yarn guide frame and avoid uneven wrapping caused by tension fluctuations.

[0016] 4. Ease of operation: The positioning groove on the movable yarn guide frame works in conjunction with the scale on the connecting rod to provide an intuitive position reference, facilitating manual calibration and emergency adjustment, and balancing the flexibility of automation and manual operation.

[0025] Example 1:

[0026] As per the instruction manual Figure 1-4 As shown, a core-spun yarn spinning device with adjustable coating thickness includes a yarn supply mechanism 1 and a thickness adjustment mechanism. The thickness adjustment mechanism includes a fixed frame 2, a movable yarn guide frame 3, a yarn guide 4, and a drive unit 5.

[0027] In this utility model, the fixing frame 2 is a frame structure, which is composed of fixing plates 6 at both ends and multiple connecting rods 7 in the middle. One fixing plate 6 is sleeved on the yarn supply mechanism 1 at the outlet end, and multiple connecting rods 7 are located at the four corners of the fixing plate 6.

[0028] In this utility model, the movable yarn guide frame 3 is slidably connected to the connecting rod 7. The top side of the movable yarn guide frame 3 is provided with a positioning groove 11 at the connecting rod 7, and the connecting rod 7 at the positioning groove 11 is provided with a corresponding position scale 12. The position scale on the connecting rod 7 at the current position can be seen through the positioning groove 11.

[0029] In this utility model, the yarn guide 4 is fixed in the middle position of the movable yarn guide frame 3. The yarn guide 4 has a yarn guide hole 9 in the middle, and the yarn guide hole 9 is a replaceable ceramic eye mold. The yarn guide hole 9 of the yarn guide 4 has different hole diameter specifications to adapt to outer wrapping fibers of different fineness. The yarn guide hole 9 is concentrically set with the yarn outlet end of the yarn supply mechanism 1.

[0030] In this utility model, a tension detector 10 is provided at the connection between the movable yarn guide frame 3 and the yarn guide 4. The tension detector 10 is arranged in a ring at equal intervals on the outside of the yarn guide 4. The tension detector 10 consists of multiple stress plates, and the stress plates are electrically connected to a signal converter. The signal converter is connected to a controller to provide tension information.

[0031] In this utility model, the drive unit 5 is located on one side of the fixed frame 2. The two ends of the drive unit 5 are extension plates 13 set on one side of the fixed frame 2. A guide rod 14 and a precision screw 15 parallel to the connecting rod 7 are arranged between the two extension plates 13. The precision screw 15 is driven to rotate by the stepper motor 16.

[0032] In this invention, the drive unit 5 is connected to a controller for setting and controlling the moving position of the moving yarn guide 3.

[0033] Working principle

[0034] 1. Coating thickness adjustment: The controller drives the stepper motor 16 to rotate according to the preset coating thickness parameters. The precision lead screw 15 drives the drive plate 8 to move linearly along the guide rod 14 through the thread transmission, thereby driving the moving yarn guide frame 3 to slide along the connecting rod 7, changing the relative position of the yarn guide 4 and the yarn supply mechanism 1 outlet end, thereby adjusting the number or thickness of the outer fiber coating layers.

[0035] 2. Dynamic tension balance: During the movement of the moving yarn guide 3, the stress plate tension detectors 10 distributed in a ring detect the tension value of the outer fiber in real time. The tension signal is converted into an electrical signal by the signal converter and transmitted to the controller. If the tension value deviates from the set threshold (such as due to yarn speed fluctuations or changes in fiber specifications), the controller adjusts the speed of the stepper motor 16 to compensate for the micro-displacement of the moving yarn guide 3 and maintain tension stability.

[0036] 3. Specification adaptation switching: For outer fibers of different fineness, replace the ceramic eye mold in the yarn guide 4 (large aperture for coarse fibers, small aperture for fine fibers) to ensure that the diameter of the yarn guide hole 9 matches the diameter of the outer fiber and avoid fiber damage or loose wrapping.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
