Description

Technical Field

[0001] This utility model relates to the field of shaping mechanisms, and in particular to a pre-twisting shaping mechanism for a winding machine. Background Technology

[0002] The pre-twisting and shaping mechanism of a twisting machine (also known as a yarn twisting machine) is a key component in textile machinery used to improve the structure of yarn or fiber bundles. Its main function is to pre-twistune and preliminarily shape the fibers before formal twisting, so as to improve the uniformity, strength and appearance quality of the final product.

[0003] The current setting process of the twirling machine usually uses carding needles or yarn separating plates with fixed spacing to evenly disperse the yarn fibers, and then the fibers enter the pre-twirling area through the yarn guide to wait for twirling.

[0004] However, existing fixed-gap carding needles and yarn separating plates usually require manual adjustment of the fiber yarn position, making it impossible to change the fiber yarn spacing without stopping the machine, which leads to fiber entanglement. To address this issue, a pre-twisting and shaping mechanism for a twisting machine is proposed. Utility Model Content

Then, the limiting frame is moved laterally to drive the support rod to move towards the middle along the top hinge point. The lateral movement of the support rod drives the balance block to move upwards as a whole. Then, the balance block drives the guide wheel upwards to provide tension for the fiber yarn.

The top set of rotating shafts 7 is used to keep the guide wheel 8 moving stably laterally while also rotating with the guide wheel 8. The outer wall of the bottom set of rotating shafts 7 is slidably connected to a balance block 6, which is used to extend the auxiliary guard plate 9 and keep it moving stably laterally. The top of the balance block 6 is fixedly connected to the auxiliary guard plate 9, which is used to drive the guide wheel 8 to move laterally. The outer wall of the top set of rotating shafts 7 is slidably connected to the guide wheel 8, which is used to lay the yarn and provide a dispersing and guiding effect. The top set of rotating shafts 7 is rotatably connected to the inner wall of the two sets of auxiliary blocks 5. The bottom set of rotating shafts 7 is fixedly connected between the two sets of auxiliary blocks 5. The inner wall of the auxiliary guard plate 9 is penetrated and slidably connected to the outer wall of the top set of rotating shafts 7. The end of the guide wheel 8 is rotatably connected to the inner side wall of the auxiliary guard plate 9.

[0032] Reference Figures 2-3 Five sets of balance blocks 6 are provided. The five sets of balance blocks 6 are connected to each other by connecting rod 10 and connecting rod 21. A threaded rod 12 is fixedly connected to the hinge shaft at the bottom of the middle set of connecting rod 10. The outer wall of threaded rod 12 is connected to threaded rod 24 through threaded sleeve 13. Threaded rod 12 and threaded rod 24 are threaded in opposite directions and are used to move in opposite directions through threaded sleeve 13. The middle end of connecting rod 10 is hinged to the outer wall of balance block 6, and the middle end of connecting rod 21 is hinged to the outer wall of balance block 6. One end of the inner wall of threaded sleeve 13 is threaded to the inner side of the outer wall of threaded rod 12, and the other end of the inner wall of threaded sleeve 13 is threaded to the inner side of the outer wall of threaded rod 24. Threaded sleeve 13 is used to extend and retract the length of threaded rod 12 and threaded rod 24. The end of threaded rod 214 is fixedly connected to the hinge shaft at the bottom of another set of connecting rod 10.

[0033] Reference Figures 3-4A set of balance blocks 6 in the middle is hinged to a support rod 15 at its front end. The support rod 15 is equipped with an elliptical reinforcing strip to provide pressure resistance. A limit frame 16 is hinged to the bottom end of the support rod 15. The limit frame 16 is used to drive the bottom end of the support rod 15 to move laterally. A slider 17 is fixedly connected to the bottom of the limit frame 16. The slider 17 is T-shaped and is used to engage with the slide groove 18 to keep the limit frame 16 moving laterally stably. The top of the base 1 has a slide groove 18 with an inwardly concave T-shaped groove to engage with the slider 17 to keep it moving laterally stably. The inner wall of the limit frame 16 is elastically connected to a limit block 20 through a limit spring 19. The limit block 20 is used to engage with the limit groove 22 to restrict the movement of the limit frame 16. A limit rod 21 is fixedly connected to the top of the limit block 20. The limit rod 21 is used to extend the limit block 20 to the top of the limit frame 16 for easy manual release. In addition to the limiting position, the base 1 has a limiting groove 22 on its top. The limiting groove 22 has grooves at equal intervals with the limiting block 20, which are used to lock the limiting block 20 in multiple positions to change the angle of the support rod 15, thereby changing the height of the guide wheel 8. The bottom of the limiting frame 16 is slidably connected to the top of the base 1. The slider 17 is slidably connected to the inner wall of the slide groove 18. One end of the limiting spring 19 is fixedly connected to the top of the inner wall of the limiting frame 16, and the other end of the limiting spring 19 is fixedly connected to the top of the limiting block 20. Through the opposing pressing force between the limiting spring 19 and the top of the inner wall of the limiting frame 16, the limiting block 20 is always locked to the inner wall of the limiting groove 22 without being affected by external forces. The limiting block 20 is slidably connected to the inner wall of the limiting frame 16. The limiting rod 21 is slidably connected to the inner wall of the limiting frame 16. The bottom end of the limiting block 20 is locked to the inner wall of the limiting groove 22.

[0034] Working principle: When dispersing fiber yarn, manually rotating the threaded sleeve 13 drives the threaded rod 12 and the threaded rod 14 to move inward or outward. Then, the threaded rod 12 and the threaded rod 14 drive multiple sets of connecting rods 10 and 11 to contract inward or expand outward. The connecting rods 10 and 11 drive the balance block 6 to move laterally on the rotating shaft 7. The balance block 6 then drives the auxiliary guard plate 9 to move laterally, and the auxiliary guard plate 9 then drives the guide wheel 8 to move laterally. This achieves the equal-distance change of the spacing of the guide wheel 8, thereby dispersing the fiber yarn and improving the stranding quality.

[0035] When the yarn loosens and collapses downwards, the limiting rod 21 is manually pulled to move the limiting block 20 out of the limiting groove 22 to release the limitation. Then, the limiting frame 16 is moved laterally to move the support rod 15 from the top hinge point to the middle. The lateral movement of the support rod 15 moves the balance block 6 upwards. The balance block 6 then moves the rotating shaft 7 and the auxiliary block 5 upwards. The auxiliary block 5 then moves the guide wheel 8 and the whole structure upwards to the required height. Finally, the limiting rod 21 is pushed downwards to move the limiting block 20 into the corresponding limiting groove 22, thus providing appropriate tension to the fiber yarn and preventing the yarn from collapsing and tangling.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
