Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a yarn doubling and winding device. Background Technology

[0002] Currently, yarn doubling involves gathering multiple yarns together using a guide roller before winding. However, when doubling multiple yarns, all yarns are gathered at once on the gathering roller, resulting in poor yarn smoothness during the gathering process. The doubled yarn is prone to localized wrinkles, leading to uneven yarn doubling and affecting yarn quality. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a yarn winding and plying device that enables multiple plying of various yarns, resulting in smoother and more stable plying and improved yarn quality after plying.

[0004] This utility model discloses a yarn winding device, including a base plate and a winding seat disposed at one end of the base plate. A winding roller is disposed on the winding seat, and a winding motor is disposed on the winding seat at one end of the winding roller. The winding motor and the winding roller are connected by transmission. A vertical plate is disposed at the other end of the base plate, and multiple yarn spindles are arrayed on the vertical plate. The yarn spindles are rotatably connected to the vertical plate and are perpendicular to the vertical plate. The yarn spindles are used to attach bobbins. At least two guide rollers are disposed above the vertical plate, and a connecting frame is disposed above the end of the vertical plate near the winding roller. A collecting wheel is disposed on the connecting frame. After some yarns on the bobbins are fused together, they enter from the first guide roller and pass through the subsequent guide rollers in sequence before entering the collecting wheel. Some yarns on the bobbins enter from the second guide roller and pass through the subsequent guide rollers in sequence or directly enter the collecting wheel. The yarn output from the collecting wheel is wound onto the winding roller.

[0005] A slide rail is installed on the base plate below the collecting wheel, parallel to the winding roller. Mounting seats are installed at both ends of the slide rail, and a lead screw is installed between the mounting seats. A slider with a screw hole is installed on the slide rail, and the lead screw is connected to the screw hole. A drive motor is installed on the mounting seat at one end of the lead screw, and the drive motor is connected to the lead screw. Two rotating shafts are installed on the slider, and guide wheels are installed on the rotating shafts. The circumferential sidewalls of the two guide wheels contact each other, and the circumferential sidewalls of the guide wheels have arc-shaped grooves. The arc-shaped grooves on the two guide wheels cooperate to form a channel for the yarn to pass through. A guide roller is installed on the base plate between the slide rail and the winding roller, with connecting seats at both ends of the guide roller. The connecting seats are fixed to the base plate, and the guide roller is rotatably connected to the connecting seats.

[0006] A fixed connecting arm is provided at the top of the slider, and a movable connecting arm is provided on the fixed connecting arm. The middle part of the fixed connecting arm and the movable connecting arm is rotatably connected by a pin, forming a scissor structure between the fixed connecting arm and the movable connecting arm. A guide wheel is provided at the end of the fixed connecting arm and the movable connecting arm near the winding roller through a rotating shaft, and a compression spring is provided between the other ends of the fixed connecting arm and the movable connecting arm.

[0007] Both the guide wheel and the collecting wheel have arc-shaped grooves on their circumferential sidewalls. The width of the arc-shaped groove on the guide wheel is greater than the width of the arc-shaped groove on the collecting wheel, and the depth of the arc-shaped groove on the guide wheel is less than the depth of the arc-shaped groove on the collecting wheel.

[0008] The yarn doubling and winding device obtained by this utility model can realize the batch doubling of multiple yarns into the corresponding guide rollers, and gather them in the collection roller to improve the stability and smoothness of yarn doubling. At the same time, the guide rollers move the yarn back and forth to improve the winding quality. Attached Figure Description

[0013] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1:

[0015] like Figures 1-4As shown, this utility model discloses a yarn winding device, including a base plate 1 and a winding seat 12 disposed at one end of the base plate 1. A winding roller 15 is disposed on the winding seat 12, and a winding motor 16 is disposed on the winding seat 12 at one end of the winding roller 15. The winding motor 16 is connected to the winding roller 15 through a transmission. A vertical plate 2 is disposed at the other end of the base plate 1, and five yarn spindles 3 are arrayed on the vertical plate 2. The yarn spindles 3 are rotatably connected to the vertical plate 2, and the yarn spindles 3 are perpendicular to the vertical plate 2. The spindle shaft 3 is used to attach the bobbin 4; two guide rollers 5 are provided above the vertical plate 2, and a connecting frame 7 is provided above the end of the vertical plate 2 near the winding roller 15. A collecting wheel 6 is provided on the connecting frame 7; after the yarn 24 on some of the bobbin 4 is fused together, it enters from the first guide roller 5 and then passes through the subsequent guide rollers 5 in sequence before entering the collecting wheel 6. After the yarn 24 on some of the bobbin 4 enters from the second guide roller 5, it directly enters the collecting wheel 6. The yarn 24 output from the collecting wheel 6 is wound onto the winding roller 15.

[0016] According to actual needs, spindle shafts 3 are arranged in a row at the lower end of the vertical plate 2. Of course, one or more rows of spindle shafts 3 can be selected according to the number of yarns 24 to be wound. In this embodiment, five spindle shafts 3 are used, arranged in a row at the lower end of the vertical plate 2. Two guide rollers 5 are arranged at intervals at the end of the vertical plate 2 near the winding roller 15, with the guide roller 5 closer to the winding roller 15 being positioned higher. In this way, the yarns 24 on the three bobbins 4 away from the winding roller 15 are directly fed into the first guide roller 5. The yarns 24 after the three yarns 24 are wound together are fed into the second guide roller 5 together with the yarns 24 on the other two bobbins 4. After being wound together again, they enter the collecting roller 6 for tightening, making the yarns 24 more compact, and then they are wound. This process makes the yarn 24 winding more stable and the yarn winding process smoother, greatly improving the quality of the yarns 24 after winding.

[0017] Of course, in other embodiments, an appropriate number of yarn cones 4 and yarn guide rollers 5 can be selected according to actual needs, and the number of yarns 24 entering each yarn guide roller 5 can also be selected according to actual needs, but generally should not exceed 4.

[0018] A slide rail 20 is provided on the base plate 1 below the collecting wheel 6. The slide rail 20 is parallel to the winding roller 15. Mounting seats 14 are provided at both ends of the slide rail 20. A lead screw 18 is provided between the mounting seats 14. A slider 8 is provided on the slide rail 20. The slider 8 is provided with a screw hole. The lead screw 18 is connected to the screw hole. A drive motor 19 is provided on the mounting seat 14 at one end of the lead screw 18. The drive motor 19 is connected to the lead screw 18. Two rotating shafts 10 are provided on the slider 8. Guide wheels 9 are provided on the rotating shafts 10. The circumferential sidewalls of the two guide wheels 9 are in contact. The circumferential sidewalls of the guide wheels 9 are provided with arc-shaped grooves 11. The arc-shaped grooves 11 on the two guide wheels 9 cooperate to form a channel for the yarn 24 to pass through. A guide roller 17 is provided on the base plate 1 between the slide rail 20 and the winding roller 15. Connecting seats 13 are provided at both ends of the guide roller 17. The connecting seats 13 are fixed on the base plate 1. The guide roller 17 and the connecting seats 13 are rotatably connected.

[0019] Since the yarn 24, after being plied together, enters the winding roller 15 after being output from the collecting wheel 6, the winding position can be controlled according to actual needs to ensure smoother and more stable winding of the winding roller 15. A slider 8 is set on the slide rail 20, and the drive motor 19 drives the lead screw 18 to rotate reciprocally, causing the slider 8 to reciprocate on the slide rail 20. The two rotating shafts 10 on the slider 8 are perpendicular to the winding roller 15, and a channel is formed between the guide wheels 9 on the rotating shafts 10 for the yarn 24 to pass through. Since the two guide wheels 9 are in contact, the channel is a closed annular structure, which can effectively restrict the yarn 24. During the reciprocating movement of the slider 8, the position of the yarn 24 entering the winding roller 15 can be controlled, and the yarn 24 will not come out of the arc-shaped groove 11, resulting in high operational stability.

[0020] The above structure has a problem: when starting, the yarn 24 after being twisted needs to be passed through the channel between the guide wheels 9, which is relatively slow and affects efficiency. Therefore, it is necessary to design the two guide wheels 9 to be adjustable so that the yarn 24 can be passed through quickly.

[0021] Specific solution: A fixed connecting arm 21 is provided on the top of the slider 8, and a movable connecting arm 22 is provided on the fixed connecting arm 21. The middle part of the fixed connecting arm 21 and the movable connecting arm 22 is rotatably connected by a pin, and a scissor structure is formed between the fixed connecting arm 21 and the movable connecting arm 22. A guide wheel 9 is provided at the end of the fixed connecting arm 21 and the movable connecting arm 22 near the winding roller 15 through a rotating shaft 10. A compression spring 23 is provided between the other ends of the fixed connecting arm 21 and the movable connecting arm 22.

[0022] To ensure the two rotating shafts 10 are at the same height, the thickness of the middle section of the movable connecting arm 22 is reduced, resulting in a structure that is thinner at both ends and in the middle. This is achieved through a pivot pin connection, forming a scissor-like structure. The guide wheels 9 located at the ends of the fixed connecting arm 21 and the movable connecting arm 22 separate as the movable connecting arm 22 rotates, facilitating the entry of the yarn 24 into the channel between the two guide wheels 5. To maintain contact between the two guide wheels 5 during operation and prevent the yarn 24 from slipping out, a compression spring 23 is installed between the movable connecting arm 22 and the fixed connecting arm 21 at the other end. This spring holds the two guide wheels 9 in a clamped state. This structure is simple to operate; the yarn feeding process only requires manual intervention to overcome the spring force of the compression spring 23 to separate the two guide wheels 5, quickly guiding the yarn 24 into the channel and improving efficiency. Of course, the spring force of the compression spring 23 can be selected according to actual needs.

[0023] Both the guide roller 5 and the gathering roller 6 have arc-shaped grooves on their circumferential sidewalls. The width of the arc-shaped groove on the guide roller 5 is greater than that on the gathering roller 6, while the depth of the arc-shaped groove on the guide roller 5 is less than that on the gathering roller 6. The relatively wide and shallow arc-shaped groove on the guide roller 5 allows the yarn 24 to remain relatively loose after being bundled, making the bundling process smoother. The relatively narrow and deep arc-shaped groove on the gathering roller 6 better gathers the yarn 24, making the yarn 24 more tightly bound, improving the density of the yarn 24, and resulting in higher overall quality.
