Description

Technical Field

[0001] This utility model relates to the field of sweater knitting technology, specifically to an automatic sweater yarn feeding device. Background Technology

[0002] Sweaters are primarily made of yarn, which is derived from animal fibers such as wool, cashmere, and mohair, or synthetic fibers such as acrylic and polyester. Sweaters made from different yarn materials have different characteristics and styles; for example, wool sweaters are warm, cashmere sweaters are soft and comfortable, and mohair sweaters have a high sheen.

[0003] For example, utility model patent CN213505300U discloses a feeding device for knitted fabric processing, including a base plate. A first groove is carved into the top of the base plate, and a placement box is slidably connected inside the first groove. A stop bar is screwed to one side of the base plate, directly below the placement box. Support plates are fixedly connected to both ends of the top of the base plate, and a conveying frame is fixedly connected to the top of the support plates. A stop plate is screwed to one side of the conveying frame, and a conveying groove is carved inside the conveying frame. Two first fixing plates are fixedly connected to one end of the bottom of the conveying groove. The advantages of this utility model are: it has a compact structure, is simple and convenient to operate, and is highly practical. By setting up a yarn feeding mechanism, the equipment prevents yarn jamming during yarn feeding. An internal pressure sensor detects the pressure during feeding; if the yarn breaks or feeding ends, the sensor sends a signal to the controller, which then activates an alarm light to alert the operator. However, a problem exists where the yarn becomes loose during feeding, causing it to wobble during knitting and feeding. This reduces knitting efficiency and leads to uneven yarn stress, potentially causing breakage. Therefore, we propose an automatic yarn feeding device for sweaters. Utility Model Content

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.

[0021] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an automatic yarn feeding device for sweater knitting, including a base plate 1. A knitting machine body 3 is fixedly connected to the upper left side of the base plate 1. A tension adjustment mechanism 4 and a yarn storage assembly 5 are provided on the upper end of the base plate 1. The tension adjustment mechanism 4 is located behind the knitting machine body 3, and the yarn storage assembly 5 is located behind the tension adjustment mechanism 4. The tension adjustment mechanism 4 includes two symmetrically arranged fixing blocks 41. Each fixing block 41 has a first sliding groove 42 at its inner end. A guide post 43 is fixedly connected to the inner wall of the first sliding groove 42. A first slider 44 is slidably connected to the outer surface of the guide post 43 and passes through the first slider 44. The outer surface of the first slider 44 is slidably connected to the first sliding groove 42. A cam 41 abuts against the lower end of each first slider 44. 2. A rotating shaft 413 is fixedly connected to the surface of the cam 412 and passes through the cam 412. A pulley 414 is fixedly connected to the rear end of the rotating shaft 413. A belt 415 is sleeved between the two pulleys 414. An L-shaped plate 416 is rotatably connected to the front end of the rotating shaft 413 through a bearing. A fixing block 41 is fixedly connected to the inner end of the L-shaped plate 416. A large gear 419 is fixedly connected to the front end of one side of the rotating shaft 413. A small gear 418 is meshed with the outer surface of the large gear 419. The output end of the second stepper motor 417 is fixedly connected to the inner end of the small gear 418 and passes through the L-shaped plate 416. The inner end of the second stepper motor 417 is fixedly connected to the L-shaped plate 416. A placement strip 45 is fixedly connected between the two first sliders 44.

[0022] In this embodiment, a second sliding groove 46 is provided at the upper end of the placement strip 45. A first stepper motor 47 is fixedly connected to one end of the placement strip 45, and the output end of the first stepper motor 47 passes through one end of the placement strip 45. A rotating rod 48 is fixedly connected to the output end of the first stepper motor 47. Two sets of symmetrically arranged cross threaded grooves are provided on the outer surface of the rotating rod 48. A second slider 410 is threadedly connected to the outer surface of the rotating rod 48. A through hole 411 is provided on the surface of each second slider 410.

[0023] Specifically, the first stepper motor 47 drives the rotating rod 48 to rotate, which in turn drives the second slider 410 to reciprocate within the second slide groove 46.

[0024] In this embodiment, the wire storage assembly 5 includes a C-shaped plate 51 fixedly connected to the upper end of the base plate 1. Two symmetrically arranged rotating circular plates 52 are rotatably connected to the upper end of the C-shaped plate 51. A post 53 is fixedly connected to the middle of the upper end of each rotating circular plate 52. A wire spool 54 is slidably connected to the outer surface of the post 53. A rotating stud 55 is threadedly connected to the upper end of the post 53. A rotating handle 56 is fixedly connected to the upper end of the rotating stud 55.

[0025] Specifically, the rotating handle 56 can be rotated through the yarn storage assembly 5. At this time, the rotating handle 56 drives the rotating stud 55 to move upward. When the rotating stud 55 disengages from the insert 53, the yarn spool 54 can be separated from the insert 53, making it convenient to replace the yarn spool 54. This improves the working efficiency of the weaving machine body 3 and reduces time loss.

[0026] In this embodiment, mounting holes 2 are provided at each corner of the upper end of the base plate 1.

[0027] Specifically, the base plate 1 and any component on the base plate 1 can be installed in a predetermined position through the mounting hole 2.

[0028] In this embodiment, the lower end of the rotating handle 56 abuts against the upper end of the charging tube 54.

[0029] Specifically, ensure that rotating the handle 56 can limit the movement of the spool 54.

[0030] In this embodiment, a blocking circular plate 49 is fixedly connected to the middle of the outer end of the rotating rod 48, and the outer diameter of the blocking circular plate 49 is larger than the outer diameter of the rotating rod 48.

[0031] Specifically, the two second sliders 410 can be separated by the blocking circular plate 49.

[0032] In this embodiment, both the first stepper motor 47 and the second stepper motor 417 are electrically connected to an external power source.

[0033] Specifically, ensure that the first stepper motor 47 and the second stepper motor 417 can operate smoothly.

[0034] Working principle: When using the device, insert the bobbin 54 into the insert post 53, then lock the stud 55 to the insert post 53. Rotate the handle 56, which in turn rotates the stud 55, causing it to move downwards. Once the lower end of the handle 56 abuts against the upper end of the bobbin 54, the installation of the bobbin 54 is complete. Next, pass the thread from the bobbin 54 through the through hole 411 and connect it to the input end of the weaving machine body 3. When the weaving machine body 3 is running, power is supplied to the first stepper motor 47. The output of the first stepper motor 47 drives the rotating rod 48 to rotate. The rotating rod 48 drives the second slider 410 to reciprocate within the second slide groove 46. The two second sliders 410 are separated by a limiting circular plate, allowing both sliders 410 to reciprocate. The 0-axis drives the thread to reciprocate, facilitating the output of the thread wound on the spool 54. When the thread wobbles during movement, power is supplied to the second stepper motor 417. The output of the second stepper motor 417 drives the pinion 418 to rotate, which in turn drives the large gear 419 to rotate at a reduced speed. The large gear 419 then drives the rotating shaft 413 to rotate, which in turn drives the cam 412 to rotate. The cam 412 then drives the first slider 44 to move upward within the first groove 42, which in turn drives the placement bar 45 to move upward. The placement bar 45 indirectly drives the thread upward, thus tightening it. This invention allows for adjustment of the tension of the thread entering the weaving machine body 3, preventing wobbling during transmission and thus preventing thread breakage. This improves the stability of the thread during transmission and increases the working efficiency of the weaving machine body 3.

[0035] 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.
