Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 3 shown, the present utility model provides a technical solution: a zero-point adjustment mechanism for a winding machine, including: a support frame 1, the support frame 1 is provided with two parallel driving parts, and a moving frame 2 is movably arranged in the height direction of the two driving parts. Both ends of the moving frame 2 are fixedly connected with a moving component, and the support frame 1 is fixedly connected with a guide plate 4 that cooperates with the moving component. By cooperating the moving component with the guide plate 4, the friction between the moving frame 2 and the support frame 1 is reduced, and the operation efficiency is improved.

[0025] The moving components include: support plates 16 fixedly arranged on the upper and lower sides of the moving frame 2. Two rollers are rotatably connected to each of the support plates 16, and the two rollers are respectively arranged on both sides of the guide plate 4. The contact area is reduced by the cooperation of the two rollers and the guide plate 4, and the friction of the moving frame 2 is reduced.

[0026] The support frame 1 is fixedly connected with a driving component, and the driving component drives the two moving frames 2 to move towards or away from each other. The driving component includes: a first motor 5 fixedly arranged on the support frame 1. The output shaft of the first motor 5 is fixedly connected with a first transmission wheel 6. The support frame 1 is rotatably connected with a driving shaft 7. The driving shaft 7 is fixedly connected with a first driving wheel 8. The first transmission wheel 6 drives the first driving wheel 8 to rotate through a first synchronous belt 9. Both ends of the driving shaft 7 are respectively fixedly connected with a first driving wheel 10 and a first driven wheel 11. The driving shaft 7 drives the two moving frames 2 to move towards or away from each other through a transmission component.

[0027] The first motor 5 mainly drives the driving shaft 7 to rotate, and the driving shaft 7 drives the first driving wheel 8, the first driving wheel 10 and the first driven wheel 11 to rotate.

[0028] The transmission component includes: a driven shaft 12. The driven shaft 12 is rotatably connected with the support frame 1 through a rotating seat. Both ends of the driven shaft 12 are respectively fixedly connected with a second driven wheel 13 and a third driven wheel 14. Fourth driven wheels 15 are arranged directly above the first driven wheel 11, the first driving wheel 10, the second driven wheel 13 and the third driven wheel 14. The fourth driven wheels 15 are adjustably connected with the support frame 1 through the support plates 16. The support frame 1 is provided with strip-shaped holes, and the support plates 16 are adjustably connected with the support frame 1 through bolts. The support frame 1 is provided with strip-shaped holes matching the support plates 16, and the specific positions of the fourth driven wheels 15 are adjusted according to the tension of the second synchronous belt 17 and the third synchronous belt 30.

[0029] The first driven wheel 11, the first driving wheel 10 and the third driven wheel 14 all drive one of the fourth driven wheels 15 to rotate through the second synchronous belt 17.

[0030] The driving shaft 7 is connected with a second driving wheel 19 through a clutch 18. The second driving wheel 19 drives the second driven wheel 13 and one of the fourth driven wheels 15 to rotate through a third synchronous belt 20. The second synchronous belt 17 and the third synchronous belt 20 are both fixedly connected with the moving frame 2 through fixing blocks. The second driving wheel 19 is connected through the clutch 18, so as to facilitate the adjustment of the relative positions of the two moving frames 2.

[0031] The first motor 5 drives a plurality of second synchronous belts 17 and a third synchronous belt 20 to cooperate with the moving frame 2. Thus, when one moving frame 2 moves upward, the other moving frame 2 moves downward. Since the first motor 5 transmits the output rotational force through the drive shaft 7, and the drive shaft 7 drives the two moving frames 2 to move towards or away from each other through the second synchronous belt 17 and the third synchronous belt 20. Since one moves upward and the other moves downward during the movement process, the rotational torque of the output shaft of the first motor 5 is minimized as much as possible, and the working efficiency is improved.

[0032] As Figures 4 to 5 shown, the moving frame 2 is fixedly connected with a wire guiding assembly. The support frame 1 is fixedly connected with a wire guiding plate 3 directly above the moving frame 2, and the wire guiding assembly extends to the upper surface of the wire guiding plate 3.

[0033] The wire guiding assembly includes: a positioning rod 21 fixedly arranged on the moving frame 2, and the positioning rod 21 is threadedly connected with the moving frame 2.

[0034] The positioning rod 21 is fitted with a wire guiding rod 23 through a universal coupling 22. Above the moving frame 2, there is a wire guiding plate 3 for the wire guiding rod 23 to pass through. The wire guiding plate 3 is provided with a through hole for the wire guiding rod 23 to pass through. The wire guiding rod 23 extends to the upper surface of the wire guiding plate 3 and is provided with a wire guiding groove for cooperating with the yarn.

[0035] In order to reduce the friction force, the through hole is fitted with the wire guiding rod 23 through a guiding assembly. The moving frame 2 drives the wire guiding rod 23 to cooperate with the guiding assembly and reciprocate linearly.

[0036] The guiding assembly includes: a groove fixed to the guiding frame 24 is provided on the lower surface of the wire guiding plate 3, and the guiding frame 24 is fixedly connected to the lower surface of the wire guiding plate 3 by screws. The guiding frame 24 is provided with a plurality of guiding wheels 25 for cooperating with the wire guiding rod 23 around the axis of the through hole. When the wire guiding rod 23 moves up and down, it will cooperate with the guiding wheels 25, thereby driving the guiding wheels 25 to rotate and reducing the friction force with the wire guiding rod 23.

[0037] The wire guiding rod 23 passes through a plurality of guiding wheels 25 and the through hole and extends to the upper surface of the wire guiding plate 3. The moving frame 2 drives the wire guiding rod 23 to cooperate with the guiding assembly and reciprocate linearly.

[0038] As Figures 1 to 6 shown, during operation, the twisting bobbin is placed on the wire guiding plate 3 by driving, and the yarn of the twisting bobbin is transported to the next working station through the wire guiding groove of the wire guiding rod 23.

[0039] Since the winding machine winds the yarn of the twisting bobbin onto a new yarn bobbin, it is necessary to drive the wire guiding rod 23 to move up and down evenly.

[0040] Therefore, the first motor 5 drives the drive shaft 7 to rotate through the first synchronous belt 9. The drive shaft 7 drives the first driving wheel 8, the first drive wheel 10, the first driven wheel 11 and the second driving wheel 19 to rotate. The first driven wheel 11, the first drive wheel 10 and the third driven wheel 14 all drive one of the fourth driven wheels 15 to rotate through the second synchronous belt 17. The second driving wheel 19 drives the second driven wheel 13 and one of the fourth driven wheels 15 to rotate through the third synchronous belt 20. Therefore, through the cooperation of multiple second synchronous belts 17 and the third synchronous belt 20 with the moving frame 2, the moving frame 2 is driven to move continuously towards or away from each other until the roving machine stops working.

[0041] When the yarn needs to be transferred for different specifications of roving bobbins, the clutch 18 is disengaged, and the first motor 5 drives the drive shaft 7 to rotate. At this time, the drive shaft 7 drives the first driving wheel 8, the first drive wheel 10 and the first driven wheel 11 to rotate, and the second driving wheel 19 does not rotate until it is adjusted to a suitable position and the clutch 18 is closed.

[0042] At this time, the first motor 5 drives the drive shaft 7 to rotate, and the drive shaft 7 drives the first driving wheel 8, the first drive wheel 10, the first driven wheel 11 and the second driving wheel 19 to rotate.

[0043] The first driven wheel 11, the first drive wheel 10 and the third driven wheel 14 all drive one of the fourth driven wheels 15 to rotate through the second synchronous belt 17.

[0044] The second driving wheel 19 drives the second driven wheel 13 and one of the fourth driven wheels 15 to rotate through the third synchronous belt 20. Therefore, through the cooperation of multiple second synchronous belts 17 and the third synchronous belt 20 with the moving frame 2, the moving frame 2 is driven to move continuously towards or away from each other until the roving machine stops working.

[0045] The embodiments disclosed in the present invention are preferred embodiments, but are not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
