Description

Technical Field

[0001] This invention relates to the field of winding device technology, specifically a winding device for knitted fabric production. Background Technology

[0002] Knitting machines are a type of textile machine, and the winding device is an essential part of knitting machines. Patent publication number CN210528112U describes a winding device for knitting machines used in the production of knitted fabrics. It includes a U-shaped bracket with a handle, insert, and winding shaft. The winding shaft has a slot, a groove, a locking plate, an arc-shaped plate, a fixing hole, a side plate, an arc-shaped groove, a limiting plate, a locking nut, and a yarn end winding device. This invention prevents yarn slippage by using a frustum-shaped side, and the yarn end winding device facilitates finding the free end of the yarn when using the same winding device again after winding, meeting production needs. Finally, the locking plate and groove prevent resource waste caused by replacing the entire arc-shaped plate if some parts are damaged.

[0003] However, when the above-mentioned winding device is used, the yarn is basically wrapped around one position on the winding shaft. The yarn cannot be evenly wrapped around the outer surface of the winding shaft, resulting in a reduction in the amount of yarn on the winding shaft. Furthermore, after a winding shaft is finished, the free end of the unwound yarn is difficult to fix quickly, which means that it takes time to find the yarn end when the yarn is wound again, causing many inconveniences to the winding process. Summary of the Invention

[0004] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a winding device for knitted fabric production, which solves the problems of yarn not being able to be evenly wound on the outer surface of the winding spool, resulting in a reduction in the amount of yarn wound on the winding spool; and, after a winding spool is finished, the free end of the unwound yarn is difficult to fix quickly, causing time to be spent finding the yarn end when the yarn is wound again, which brings many inconveniences to the winding process.

[0005] Technical solution To achieve the above objectives, the present invention provides the following technical solution: a winding device for knitted fabric production, comprising a mounting disc, a rotating shaft rotatably connected through the surface of the mounting disc, a rotating guide column fixedly connected to the top end of the rotating shaft, a power assembly for driving the rotating guide column to rotate mounted on the lower surface of the mounting disc, a winding sleeve slidably connected to the outer surface of the rotating guide column, a reset assembly connected to the top of the winding sleeve, a lifting assembly connected between the bottom of the winding sleeve and the upper surface of the mounting disc, four side fixing plates fixedly connected to the outer surface of the mounting disc, a support rod fixedly connected to the upper surface of one of the side fixing plates, a lower fixing strip fixedly connected to the top end of the support rod, an upper fixing strip fixedly connected to the lower fixing strip via two vertical fixing strips, two hollow round tubes fixedly connected between the upper and lower fixing strips, multiple air suction holes formed on the outer wall of the hollow round tubes, an air suction assembly connected to the two hollow round tubes connected to the upper surface of another side fixing plate, and a dust suction assembly connected to the outer surface of the mounting disc.

[0006] Preferably, the power assembly includes a servo motor fixedly connected to the lower surface of the mounting disc. The output shaft of the servo motor is fixedly connected to a first pulley, and the bottom end of the rotating shaft is fixedly connected to a second pulley. The first pulley and the second pulley are connected by a belt drive. When the servo motor is started, the output shaft of the servo motor rotates the first pulley, the second pulley rotates the rotating shaft, the rotating shaft rotates the rotating guide column, and the rotating guide column rotates the winding sleeve.

[0007] Preferably, a sliding strip is fixedly connected to the inner wall of the winding sleeve, and a sliding groove is provided on the outer surface of the rotating guide post. The sliding strip is slidably connected inside the sliding groove, so that the rotating guide post can rotate synchronously with the winding sleeve, and the winding sleeve can slide on the outer surface of the rotating guide post.

[0008] Preferably, the reset assembly includes four guide connecting rods fixedly connected to the top of the winding sleeve. A positioning disc is fitted on the outer surface of the four guide connecting rods. The positioning disc is bolted to the top of the rotating guide column. A reset spring is fitted on the outer surface of the guide connecting rod. One end of the reset spring is fixedly connected to the top of the winding sleeve, and the other end of the reset spring is fixedly connected to the lower surface of the positioning disc.

[0009] Preferably, the lifting assembly includes a drive connecting shaft fixedly connected to the bottom of the winding sleeve. An arc-shaped contact block is fixedly connected to one end of the drive connecting shaft away from the winding sleeve. An inclined fixing column is fixedly connected to the upper surface of the mounting disc. The inclined fixing column is located outside the rotating guide column. The arc-shaped contact block contacts the inclined surface of the inclined fixing column. The winding sleeve moves with the arc-shaped contact block through the drive connecting shaft. When the arc-shaped contact block rises at the top of the inclined fixing column, the winding sleeve rises. When the arc-shaped contact block falls at the top of the inclined fixing column, the winding sleeve falls, thereby causing the winding sleeve to move up and down continuously.

[0010] Preferably, the suction assembly includes a negative pressure pump fixedly connected to the upper surface of the side fixing plate. The inlet of the negative pressure pump is fixedly connected to a first connecting pipe. The end of the first connecting pipe away from the negative pressure pump is fixedly connected to a second connecting pipe. The end of the second connecting pipe away from the first connecting pipe is fixedly connected to a third connecting pipe. The lower surface of the third connecting pipe is fixedly connected to two fourth connecting pipes. The bottom ends of the two fourth connecting pipes are respectively fixedly connected to corresponding hollow round tubes. Through the action of the negative pressure pump, the multiple suction holes on the two hollow round tubes generate suction force, and then the wound yarn is cut short, so that the unwound yarn ends are fixed on the two hollow round tubes.

[0011] Preferably, two guide rollers are rotatably connected to the upper surface of one of the side fixing plates, and an upper sealing plate is provided above the guide rollers. Both guide rollers are rotatably connected to the upper sealing plate.

[0012] Preferably, each of the four side fixing plates has a vertical fixing post fixedly connected to its lower surface, and a mounting plate is fixedly connected to the end of the vertical fixing post away from the side fixing plate. Two mounting holes are formed through the surface of the mounting plate.

[0013] Preferably, the vacuuming assembly includes a connecting mounting base fixedly connected to the outer surface of the mounting disc. A vacuum cleaner is fixedly connected to the upper surface of the connecting mounting base. A fifth connecting pipe is fixedly connected to the inlet of the vacuum cleaner. A vacuum head is fixedly connected to the end of the fifth connecting pipe away from the vacuum cleaner. When the vacuum cleaner is started, debris such as loose threads from the yarn enters the interior of the fifth connecting pipe through the vacuum head and then enters the interior of the vacuum cleaner through the fifth connecting pipe.

[0014] Beneficial effects This invention provides a winding device for knitted fabric production. It has the following advantages: This invention involves starting a vacuum cleaner, which draws out loose threads and other debris from the yarn through the suction head into the fifth connecting pipe. The debris is then removed from the yarn surface. A negative pressure pump is then activated, creating suction through multiple air holes on the two hollow tubes. The wound yarn is then cut short, securing the unwound threads to the two hollow tubes. When rewinding the yarn, the unwound threads can be quickly picked up and secured to the winding sleeve.

[0015] This invention involves starting a servo motor, whose output shaft rotates a first pulley, a second pulley rotates a rotating shaft, the rotating shaft rotates a rotating guide post, and the rotating guide post rotates a winding sleeve. This causes the yarn to wind onto the outer surface of the winding sleeve. As the winding sleeve rotates, it moves an arc-shaped contact block via a drive connecting shaft. When the arc-shaped contact block rises above the inclined fixed post, the winding sleeve rises; when the arc-shaped contact block falls below the inclined fixed post, the winding sleeve falls. This continuous rising and falling motion of the winding sleeve ensures that the yarn is evenly wound around its outer surface, significantly increasing the amount of yarn wound.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example: like Figures 1-6 As shown, this embodiment of the invention provides a winding device for knitted fabric production, including a mounting disc 1. A rotating shaft is rotatably connected through the surface of the mounting disc 1. A rotating guide column 2 is fixedly connected to the top of the rotating shaft. A power assembly for driving the rotating guide column 2 to rotate is mounted on the lower surface of the mounting disc 1. The power assembly includes a servo motor 12 fixedly connected to the lower surface of the mounting disc 1. A first pulley is fixedly connected to the output shaft of the servo motor 12. A second pulley is fixedly connected to the bottom of the rotating shaft. The first pulley and the second pulley are connected by belt drive. When the servo motor 12 is started, the output shaft of the servo motor 12 drives the first pulley to rotate, the second pulley drives the rotating shaft to rotate, the rotating shaft drives the rotating guide column to rotate, and the rotating guide column drives the winding sleeve 3 to rotate. A winding sleeve 3 is slidably connected to the outer surface of the rotating guide post 2. A sliding strip 5 is fixedly connected to the inner wall of the winding sleeve 3. A sliding groove 4 is opened on the outer surface of the rotating guide post 2. The sliding strip 5 is slidably connected inside the sliding groove 4. A reset assembly is connected to the top of the winding sleeve 3. The reset assembly includes four guide connecting rods 6 fixedly connected to the top of the winding sleeve 3. A positioning disc 7 is fitted on the outer surface of the four guide connecting rods 6. The positioning disc 7 is bolted to the top of the rotating guide post 2, so that the winding sleeve 3 can be separated from the rotating guide post 2. A reset spring 8 is fitted on the outer surface of the guide connecting rods 6. One end of the reset spring 8 is fixedly connected to the top of the winding sleeve 3, and the other end of the reset spring 8 is fixedly connected to the lower surface of the positioning disc 7. A lifting assembly is connected between the bottom of the winding sleeve 3 and the upper surface of the mounting disc 1. The lifting assembly includes a drive connecting shaft 10 fixedly connected to the bottom of the winding sleeve 3. An arc-shaped contact block 11 is fixedly connected to the end of the drive connecting shaft 10 away from the winding sleeve 3. An inclined fixing column 9 is fixedly connected to the upper surface of the mounting disc 1. The inclined fixing column 9 is located outside the rotating guide column 2. The arc-shaped contact block 11 contacts the inclined surface of the inclined fixing column 9. The winding sleeve 3 moves with the arc-shaped contact block 11 through the drive connecting shaft 10. When the arc-shaped contact block 11 rises at the top of the inclined fixing column 9, the winding sleeve 3 rises. When the arc-shaped contact block 11 falls at the top of the inclined fixing column 9, the winding sleeve 3 falls, thereby making the winding sleeve 3 move up and down continuously. Four side fixing plates 13 are fixedly connected to the outer surface of the mounting disc 1. A support rod is fixedly connected to the upper surface of one of the side fixing plates 13. A lower fixing strip is fixedly connected to the top of the support rod. The lower fixing strip is fixedly connected to an upper fixing strip 16 through two vertical fixing strips 17. Two hollow round tubes 18 are fixedly connected between the upper fixing strip 16 and the lower fixing strip. Multiple air suction holes 19 are opened on the outer wall of the hollow round tubes 18. An air suction assembly connected to the two hollow round tubes 18 is connected to the upper surface of the other side fixing plate 13. The air suction assembly includes a negative pressure pump 20 fixedly connected to the upper surface of the side fixing plate 13. The inlet of the negative pressure pump 20 is fixedly connected to... The first connecting pipe 21 is fixedly connected to the end of the first connecting pipe 21 away from the negative pressure pump 20, and the second connecting pipe 22 is fixedly connected to the end of the second connecting pipe 22 away from the first connecting pipe 21, and the lower surface of the third connecting pipe 23 is fixedly connected to two fourth connecting pipes 24. The bottom ends of the two fourth connecting pipes 24 are fixedly connected to the corresponding hollow round tubes 18 respectively. When the negative pressure pump 20 is started, the multiple suction holes 19 on the two hollow round tubes 18 generate suction force through the action of the negative pressure pump 20. Then the wound yarn is cut short, so that the unwound yarn ends are fixed on the two hollow round tubes 18. Two guide rollers 25 are rotatably connected to the upper surface of one of the side fixing plates 13. An upper sealing plate 26 is provided above the guide rollers 25. Both guide rollers 25 are rotatably connected to the upper sealing plate 26. Vertical fixing columns 14 are fixedly connected to the lower surfaces of the four side fixing plates 13. An mounting plate 15 is fixedly connected to the end of the vertical fixing column 14 away from the side fixing plate 13. Two mounting holes are opened through the surface of the mounting plate 15. A dust collection assembly is connected to the outer surface of the mounting disc 1. The dust collection assembly includes a connecting mounting seat fixedly connected to the outer surface of the mounting disc 1. A vacuum cleaner 27 is fixedly connected to the upper surface of the connecting mounting seat. A fifth connecting pipe 28 is fixedly connected to the inlet of the vacuum cleaner 27. A vacuum head 29 is fixedly connected to the end of the fifth connecting pipe 28 away from the vacuum cleaner 27. When the vacuum cleaner 27 is started, the thread ends and other debris on the yarn enter the interior of the fifth connecting pipe 28 through the vacuum head 29 and then enter the interior of the vacuum cleaner 27 through the fifth connecting pipe 28.

[0020] Working principle: In use, the yarn is passed through two guide rollers 25, then passes around two hollow tubes 18 in an S-shape, and finally fixed on the outer surface of the winding sleeve 3. The servo motor 12 is started, and the output shaft of the servo motor 12 drives the first pulley to rotate, the second pulley drives the rotating shaft to rotate, the rotating shaft drives the rotating guide post 2 to rotate, and the rotating guide post 2 drives the winding sleeve 3 to rotate, so that the yarn is wound around the outer surface of the winding sleeve 3. When the winding sleeve 3 rotates, the winding sleeve 3 moves with the arc-shaped contact block 11 through the drive connecting shaft 10. When the arc-shaped contact block 11 rises at the top of the inclined fixed post 9, the winding sleeve 3 rises. When the arc-shaped contact block 11 falls at the top of the inclined fixed post 9, the winding sleeve 3 falls. Thus, the winding sleeve 3 moves up and down continuously, so that the yarn is evenly wound on the outer surface of the winding sleeve 3, which greatly increases the amount of yarn wound. When winding the yarn, start the vacuum cleaner 27. Through the action of the vacuum cleaner 27, the yarn ends and other debris enter the interior of the fifth connecting pipe 28 through the vacuum head 29, and then enter the interior of the vacuum cleaner 27 through the fifth connecting pipe 28 to remove the debris from the surface of the yarn. After the winding sleeve 3 has finished winding, the negative pressure pump 20 is started. The negative pressure pump 20 causes the multiple air holes 19 on the two hollow round tubes 18 to generate suction. Then the wound yarn is cut short, so that the unwound yarn ends are fixed on the two hollow round tubes 18.
