Description

Technical Field

[0001] This invention relates to the field of vortex spinning equipment technology, and in particular to an alternating feeding device for vortex spinning. Background Technology

[0002] Vortex spinning is a process of directly spinning fiber slivers into packaged yarns. Like other new types of spinning, it eliminates the need for two processes: roving and winding. Because vortex spinning has a very low breakage rate and minimal waste yarn loss, the yield is as high as 99% or more, which can effectively improve the efficiency of textile processing.

[0003] Chinese invention patent CN116837498A discloses an alternating feeding device for vortex spinning, comprising a transmission device, a feeding device, profile supports, and a material changing device. Profile supports are located at the four corners of the lower end face of the transmission device, and a feeding device is located at the center of the lower end face of the transmission device. Six sets of material changing devices are evenly and equidistantly rotatably engaged on the inner end face of the feeding device. Each material changing device includes a support guide for support, and the outer end face of the support guide has symmetrically formed limiting grooves. This patent, by setting up a transmission device, allows a servo motor to intermittently drive the limiting guide shaft to rotate via a fixed turntable and connecting teeth during alternating feeding of vortex spinning. This enables the material changing device to cyclically position itself at the bottom of the fixed slide, while the fixed slide is positioned inside the limiting guide shaft, thereby completing rapid and precise alternating feeding, improving feeding efficiency and stability.

[0004] However, the above patents still have shortcomings: 1. This invention guides the fibers into the guide chute, and then uses an external pushing mechanism to push all the fibers in the guide chute toward the inlet of the fixed slide. The fibers at the very front can gradually fall into the fixed slide. The fibers need to remain upright during this process, otherwise the fibers cannot enter the fixed slide. However, the external pushing mechanism cannot position all the fibers during the movement. Therefore, once the fibers tilt, they cannot enter the fixed slide, thus affecting the quality of fiber feeding; 2. This invention guides the fibers to the limiting clip shaft through the fixed slide. The fibers undergo free fall during the guidance process. The fibers generate a large potential energy during the fall, meaning that the bottom of the fibers will hit the support guide seat, which can easily damage the fibers. Summary of the Invention

[0005] The technical problem to be solved by this invention is: how to ensure that the fiber remains upright during introduction and how to avoid accidental damage to the bottom of the fiber.

[0010] Preferably, both ends of the arc-shaped guide rod are provided with limiting heads.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In this embodiment, such as Figures 1 to 7As shown, an alternating feeding device for vortex spinning includes a support plate 1. A bevel gear 11 is rotatably engaged at the top center of the support plate 1. A servo motor 12 is located beside the bevel gear 11. A fixed turntable 13 is mounted on the output end of the servo motor 12. Connecting teeth are evenly and equidistantly arranged on the outer wall of the fixed turntable 13. A fixed slide cylinder 14 and four rectangularly distributed profile supports 15 are provided at the bottom of the support plate 1. An annular groove is opened at the top of the support plate 1. A connecting groove communicating with the fixed slide cylinder 14 is provided at the bottom of the annular groove. An annular slide frame 16 is slidably arranged in the annular groove. A plurality of feed inlets 161 are arranged at equal angles along its circumference on the bottom wall of the annular slide frame 16. The feed inlets 161 are provided with a feeding port for feeding... The locking mechanism 2 is used to position and lock the fibers. On one side of the annular slide groove, there is an unlocking mechanism 3 for unlocking the locking mechanism 2. On the other side of the annular slide groove, there is a driving mechanism 4 for driving the annular slide frame 16 to rotate. At the bottom center of the support plate 1, there is a linkage shaft 17 connected to the bevel gear 11. At the bottom of the linkage shaft 17, there is a rotating plate 18. Several connecting slots 181 are set at equal angles along its circumference on the rotating plate 18. A receiving mechanism 5 is rotatably installed in the connecting slots 181 to receive the fibers falling from the fixed slide cylinder 14. A buffering mechanism 6 is provided on the receiving mechanism 5 to buffer the falling fibers. Several rotating motors 182 are provided on the rotating plate 18 to drive the receiving mechanism 5 to rotate.

[0032] This invention still uses a servo motor 12 to drive a fixed turntable 13 to rotate, and then uses connecting teeth to drive a bevel gear 11 to rotate intermittently. The bevel gear 11 drives the linkage shaft 17 and the rotating plate 18 to rotate synchronously. Before feeding, the fibers are placed into all the locking mechanisms 2 of the annular slide frame 16 in sequence. The locking mechanisms 2 lock the fibers. The locking mechanism 2 includes an arc-shaped guide rod 21 and a guide slide plate 22. The arc-shaped guide rod 21 has a connecting plate 211 in the middle, and springs 212 are provided at both ends of the connecting plate 211. There are two guide slide plates 22, and the inner side wall of the guide slide plate 22 is provided with a clearance groove. 221, the top of the guide slide plate 22 is provided with an arc-shaped baffle 23 for positioning the fiber sidewall. An L-shaped connecting rod 24 is provided on the side of the arc-shaped baffle 23. The L-shaped connecting rod 24 is provided with a guide hole that slides with the arc-shaped guide rod 21. The connecting plate 211 is fixedly connected to the sidewall of the annular slide frame 16. The two guide slide plates 22 are symmetrically slidably arranged at the feed inlet 161 of the annular slide frame 16. The two L-shaped connecting rods 24 are connected to the arc-shaped guide rod 21 through the guide hole. The two springs 212 are both sleeved on the arc-shaped guide rod 21, and the two springs 212 are respectively connected to the sidewall of the two L-shaped connecting rods 24.

[0033] The fiber is placed between the two arc-shaped baffles 23. The two L-shaped connecting rods 24 are pulled by the pulling force of the two springs 212. The two L-shaped connecting rods 24 can be guided to rotate relative to each other around the axis of the bevel gear 11 through the cooperation of the arc-shaped guide rod 21 and the guide hole. The two L-shaped connecting rods 24 drive the two guide slides 22 to move relative to each other in the annular slide frame 16. The two guide slides 22 drive the two arc-shaped baffles 23 to position and clamp the fiber.

[0034] The fiber positioning clamp can be released by the unlocking mechanism 3. The unlocking mechanism 3 includes an unlocking cylinder 31 and an arc-shaped abutment block 32. Both ends of the arc-shaped abutment block 32 are provided with a first wedge surface 321. The L-shaped connecting rod 24 is provided with a second wedge surface 241 that cooperates with the first wedge surface 321. The unlocking cylinder 31 is horizontally set on the top of the support plate 1, and the arc-shaped abutment block 32 is set on the output end of the unlocking cylinder 31.

[0035] The arc-shaped abutment block 32 is driven by the unlocking cylinder 31 to move between the two L-shaped connecting rods 24. The two first wedge surfaces 321 on the arc-shaped abutment block 32 can respectively abut against the second wedge surfaces 241 of the two L-shaped connecting rods 24. The wedge surfaces of the first wedge surfaces 321 and the second wedge surfaces 241 can be used to allow the L-shaped connecting rods 24 to move on the arc-shaped guide rod 21. The two L-shaped connecting rods 24 move in opposite directions. The two L-shaped connecting rods 24 drive the two guide slide plates 22 to move in opposite directions within the annular slide frame 16. The arc-shaped baffles 23 on the guide slide plates 22 also move accordingly. The two arc-shaped baffles 23 rotate in opposite directions around the axis of the bevel gear 11. The distance between the two arc-shaped baffles 23 gradually increases, and the fiber can fall from the two guide slide plates 22. The guide slide plates 22 are provided with an inner chamfer 222 that connects with the avoidance groove 221. The inner chamfer 222 can keep the fiber always centered and prevent it from shifting. The fiber can fall into the corresponding feed port 161.

[0036] Furthermore, both ends of the arc-shaped guide rod 21 are provided with limiting heads 213. The limiting heads 213 can limit the position of the two L-shaped connecting rods 24 moving in opposite directions, so as to prevent the L-shaped connecting rods 24 from accidentally detaching from the arc-shaped guide rod 21.

[0037] The drive mechanism 4 drives the annular slide frame 16 to rotate within the annular groove so that all fibers can be conveyed sequentially. The drive mechanism 4 includes an L-shaped bracket 41, a drive motor 42, a drive gear 43, and a gear ring 44. The L-shaped bracket 41 is set on the top of the support plate 1. The drive motor 42 is vertically set on the top of the L-shaped bracket 41. The drive gear 43 is connected to the output end of the drive motor 42. The gear ring 44 is set on the outer wall of the annular slide frame 16 and meshes with the drive gear 43.

[0038] The drive motor 42 drives the drive gear 43 to rotate, the drive gear 43 drives the gear ring 44 to rotate, and the gear ring 44 drives the annular slide frame 16 to rotate in the annular slide groove. The fibers in all the locking mechanisms 2 in the annular slide frame 16 can move synchronously. After a feed port 161 is connected to the docking groove, the locking mechanism 2 is unlocked by the unlocking mechanism 3, and the fiber can fall into the feed port 161. It enters the fixed slide cylinder 14 through the feed port 161 and the docking groove, and is then received by the buffer mechanism 6 and the receiving mechanism 5.

[0039] The receiving mechanism 5 includes a support guide 51 and a limiting pin 52. The support guide 51 is rotatably disposed in the connecting groove 181, and the limiting pin 52 is fixedly connected to the center of the support guide 51. The output end of the rotating motor 182 is connected to the support guide 51, and the buffer mechanism 6 is installed on the support guide 51 and the limiting pin 52.

[0040] The buffer mechanism 6 includes a buffer motor 61, a screw 62, an outer support rod 63, and a length compensation rod 64. There are three outer support rods 63, one end of which has a guide arc surface 631. The length compensation rod 64 has three circumferentially arranged inner grooves 641 on its outer wall near its top. The bottom of the length compensation rod 64 has a threaded hole 642 that mates with the screw 62. The limiting shaft 52 has a sliding hole 521 that slides and retracts with the length compensation rod 64. The top of the limiting shaft 52 has an outer chamfer 522. The buffer motor 61 is located at the bottom of the support guide 51. The length compensation rod 64 is slidably disposed in the sliding hole 521. The screw 62 is located in the sliding hole 521. One end of the screw 62 is fixedly connected to the output end of the buffer motor 61, and the other end of the screw 62 is connected to the threaded hole 642. The other end of the outer support rod 63 is rotatably disposed at the lower end of the inner groove 641.

[0041] Before the unlocking mechanism 3 operates, the buffer motor 61 prioritizes driving the screw 62 to rotate. The screw 62 engages with the threaded hole 642 of the length compensation rod 64, allowing the length compensation rod 64 to gradually rise within the sliding hole 521. The length compensation rod 64 can then extend into the fixed sliding cylinder 14. Simultaneously, the three outer support rods 63 can rotate outwards using eccentric gravity, meaning the outer support rods 63 can extend out of the inner groove 641. To ensure the stable extension of the outer support rods 63 from the inner groove 641, a rubber pad 643 is provided on the inner wall of the upper end of the inner groove 641. The rubber pad 643 deforms when squeezed by the outer support rods 63. After the outer support rods 63 lose the pressure from the inner wall of the sliding hole 521, the rubber pad 643 uses its own elasticity to resist the outer support rods 63. As the fiber rotates outward from the inner groove 641, the three outer support rods 63 can receive the fiber falling into the fixed slide cylinder 14. Then, the buffer motor 61 drives the screw 62 to rotate in the opposite direction. The screw 62 drives the length compensation rod 64 to move downward. The length compensation rod 64 can gradually enter the slide hole 521. The three outer support rods 63 retract into the corresponding inner groove 641 by abutting against the top of the limiting pin 52. That is, the outer support rods 63 can rotate in the opposite direction and enter the inner groove 641. After that, the fiber is separated from the support of the three outer support rods 63. The fiber can enter the limiting pin 52 by the guidance of the outer chamfer 522. After that, the fiber enters the limiting pin 52. Since the fiber is buffered, the bottom of the fiber is not damaged when it enters the limiting pin 52.

[0042] The present invention also includes a buffer receiving box 7, on both sides of the outer wall of the head end of the buffer receiving box 7, a synchronous shaft 71 is provided, a horizontal plate 8 is provided between the two profile support columns 15, and two symmetrically arranged rotating seats 81 are provided on the horizontal plate 8. An angle adjustment motor 82 is provided on one of the rotating seats 81. The buffer receiving box 7 is rotatably mounted on the two rotating seats 81 through the synchronous shaft 71, and the output end of the angle adjustment motor 82 is connected to one of the synchronous shafts 71.

[0043] The receiving mechanism 5 is driven to rotate by the rotating motor 182, and the waste material on the receiving mechanism 5 is released into the buffer receiving box 7. The buffer receiving box 7 can buffer the waste material. When it is necessary to discharge the waste material, the buffer receiving box 7 is driven to rotate around the axis of the synchronous shaft 71 by the angle adjustment motor 82, so that the waste material in the buffer receiving box 7 can be automatically poured out.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
