Description

Technical Field

[0001] The present invention relates to the technical field of high-speed knitting machine tracks, and particularly to a multi-stage track slide structure of a high-speed knitting machine. Background Art

[0002] Traditional high-speed knitting machines are also known as maypole knitting machines. In a maypole knitting machine, the circulating track of the spindles is sinusoidal or reverse sinusoidal. The spindles rotate from the inner chord to the outer chord or from the outer chord to the inner chord, and the knitting thread changes from short to long or from long to short. The knitting thread is knitted with extremely high-frequency changes.

[0003] In the prior art, during the rotation of the spindles around the circulating track, the spindles are slidably mounted on the circulating track through sliders. When transitioning between spindle driving members, the sliders will collide with the circulating track, easily causing deformation damage and excessive noise, and having a high frequency of maintenance problems.

[0004] Furthermore, currently, the concentric movement space of the circulating track is large, and the tension compensation for the running of the knitting thread is insufficient, easily causing the phenomena of wire splitting and back wire of the knitting thread, increasing the design difficulty of the spindles and restricting the improvement of the knitting machine speed.

[0005] Furthermore, due to the long circulating track and large rotation range, the wave force of the knitting thread is relatively large, and the overall operation cannot ensure flexible and reliable movement, resulting in a reduction in the knitting machine speed. Summary of the Invention

[0006] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a multi-stage track slide structure of a high-speed knitting machine, which realizes the sliding rotation of the spindles around the track assembly, enables the spindles to perform concentric rotational motion, solves the traditional motion mode of the sliders and the circulating track, and realizes the advantages of fast wire release and low noise. Since the track set by the track assembly is a circular track, it meets the technical effects of a small movement track range of the spindles and stable relaxation of the wire release tension. Through the setting of the cycloid limit assembly, when the spindles slide on the track, the driving cam drives the swing rod to swing up and down, realizing that the wire release track is approximately a horizontal circular track, solving the problem of a large running track range of the spindles, and realizing the characteristics that the running tracks between the spindles are concentric and the running track range is small, improving the wire outlet speed and being more in line with the running law of the spindles.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: A multi-stage track slide structure of a high-speed knitting machine, including a track assembly and a cycloid limit assembly. The track assembly includes a first slide plate in a cylindrical structure and a second slide plate in a circular structure. The first slide plate and the second slide plate are integrally formed. The middle part of the second slide plate is set as a through-hole structure. A second slide plate is arranged at the vertical bottom of the first slide plate along its axial direction. The outer side of the second slide plate is perpendicularly installed with the first slide plate. An annular groove is formed on the upper surface of the second slide plate. Trajectory limit plates are respectively arranged on both sides of the inner bottom of the annular groove along its diameter direction. A first track is formed between the two trajectory limit plates and the upper part of the inner side of the annular groove. A plurality of cycloid limit assemblies are evenly distributed on the outer circumferential surface of the first slide plate. A receiving long slot is formed in the middle of the cycloid limit assembly. The receiving long slot extends towards the axis direction of the first slide plate, so that the first slide plate and the second slide plate are respectively provided with openings, and the openings formed by the two are formed into a special-shaped opening. A first track plate is arranged at the top of the first slide plate.

[0008] Preferably, a second track plate is arranged on the inner surface of the first slide plate. The second track plate and the first track plate are arranged at intervals, and the interval between the two forms a second track.

[0009] Preferably, the inner surface of the first track plate is set as a first track surface, and the outer surface of the first track plate is set as a second track surface.

[0010] Preferably, the inner surface of the second slide plate is set as a third track surface.

[0011] In summary, the present invention provides a multi-stage track slide structure of a high-speed knitting machine, which realizes the running track of concentric wire feeding between spindles. By rolling the rollers with the tracks and track surfaces, the characteristics of low noise and small running track are realized. The running track between the spindles rotates along the concentric direction. And by driving the upper and lower swing of the cycloid component on the cycloid component through the driving cam, the wire feeding track is approximately in a horizontal circular track for wire feeding, so that the wire feeding track range is smaller, the wire outlet speed is increased, and the knitting quality is improved;

[0012] Specifically: The first track surface on the inner surface of the first track plate is rollingly installed with a first roller, the second track surface on the outer surface of the first track plate is rollingly installed with a second roller, the second track is rollingly installed with a third roller, the first track is rollingly installed with a fourth roller, and the third track surface on the inner side of the second slide plate is rollingly installed with a fifth roller.

[0013] By sliding the rolling components on the track assembly, the spindle base rotates around the track on the track assembly, and the rotation of each spindle base around the concentric track is realized.

[0014] The installation direction of the rollers on the track or rail surface is specifically as follows: the axis of roller three is perpendicular to the axis of slide plate two, and the axes of roller one, roller two, roller four, and roller five are all parallel to the axis of slide plate two. This enables the rolling assembly to roll in two directions, horizontal and vertical, within the track assembly, ensuring stable rolling motion and enabling movement along a specific weaving trajectory.

[0015] The cooperation mode of the cycloid limit component and the cycloid component is that the cycloid rod on the cycloid component drives the upper and lower swing rods by driving the cam to rotate. When a short side length engages for driving, the cycloid rod quickly swings out from the accommodating long slot. When the driving cam engages and rotates to a long side length, the cycloid rod slowly swings downward and swings into the accommodating long slot. When the driving cam engages and rotates to another short side length, the cycloid rod quickly swings out of the accommodating long slot. When the driving cam engages and rotates to another long side length, the cycloid rod slowly swings upward and swings into the accommodating long slot. Thus, a trapezoidal wire-releasing trajectory is formed. Since the swing at the long side length is slow, the formed trajectory is a horizontal line trajectory, and the swing at the short side length is rapid, forming a vertical trajectory. Since the length of the vertical trajectory is much smaller than that of the horizontal line trajectory, the wire-releasing trajectory approximately forms a concentric circle trajectory, which more conforms to the wire-releasing motion law of the spindle, achieving the characteristics of fast wire-releasing speed, good weaving quality, and stable wire-releasing tension.

Embodiment

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] As Figures 1 to 6 shown:

[0025] As Figure 1 , 2 shown, the present invention is a multi-stage track slideway structure of a high-speed knitting machine, including a track assembly and a cycloid limit component 1. The track assembly includes a slide plate one 2 with a cylindrical structure and a slide plate two 3 with a circular structure. The slide plate one 2 with a cylindrical structure is used to accommodate the rolling components, and the slide plate two 3 with a circular structure is used to support the rolling of the roller four 32 on the rolling components. The slide plate one 2 and the slide plate two 3 are integrally formed. The middle part of the slide plate two 3 is set as a through-hole structure, and the motor drive assembly is installed through the middle through-hole of the slide plate two 3 for driving the driving cam, driving gear 36, driving gear one 33, and driving gear two 34. The slide plate two 3 is arranged perpendicular to the vertical bottom of the slide plate one 2 along the axis direction of the slide plate one 2. The outer side of the slide plate two 3 is perpendicularly installed with the slide plate one 2. An annular groove 4 is formed on the upper surface of the slide plate two 3. On both sides of the inner bottom of the annular groove 4 along its diameter direction, track limit plates 5 are respectively arranged. An track one 6 is formed between the two track limit plates 5 and the surface of the annular groove 4 inside the driving gear one 33 on the upper part. A plurality of cycloid limit components 1 are evenly distributed on the outer circumferential surface of the slide plate one 2. An accommodation long strip opening 14 is formed in the middle of the cycloid limit component 1. The accommodation long strip opening 14 extends towards the axis direction of the slide plate one 2, so that the slide plate one 2 and the slide plate two 3 are respectively provided with openings, and the openings formed by the two form a special-shaped opening 7. A track plate one 11 is arranged at the top of the slide plate one 2.

[0026] Preferably, as Figure 1 shown, the inner surface of the slide plate one 2 is provided with a track plate two 12. The track plate two 12 and the track plate one 11 are arranged at intervals, and the interval between the two forms a track two 13.

[0027] Preferably, as Figure 1 shown, the inner surface of the track plate one 11 is set as a track surface one, and the outer surface of the track plate one 11 is set as a track surface two.

[0028] Preferably, as Figure 1As shown, the inner surface of the second skateboard 3 is set as the third rail surface.

[0029] As Figure 1 , 2 , 3, and 4 show that a rolling component is slidably mounted on the track assembly. The rolling component includes a rack bar 15, a mounting base 16, and an assembly gusset 17. A number of rack bars 15 are provided on the upper part of the second skateboard 3. A mounting base 16 is provided at the top of the rack bar 15. The middle part of the mounting base 16 is used to mount a spindle base 21, a wire deflecting rod 22, and a wire outlet roller 23. Two roller ones 24 are distributed on both sides in the length direction of the mounting base 16. An assembly gusset 17 is provided above the two roller ones 24. The rack bar 15, the mounting base 16, the assembly gusset 17, and the second skateboard 3 are all coaxially arranged. In this embodiment, 16 rack bars 15 are selected as an example. The number of selected rack bars 15 should follow more than 8 and be a multiple of 4. The inner surface of the rack bar 15 is set as a gear surface 25, and the outer surface is set as a smooth surface. On one side of the assembly gusset 17 away from its axis and along the axial direction, two roller twos 26 are provided. The roller twos 26 are provided at the bottom of the assembly gusset 17. Four roller threes 31 are provided on the outer surface of the mounting base 16 along its axial direction. Three roller fours 32 are provided at the bottom of the rack bar 15 along its axial direction. The gear surface 25 on the inner side of the rack bar 15 is meshed and connected to a driving gear one 33. On the side of the driving gear one 33 away from the rack bar 15, it is meshed and connected to a driving gear two 34. The driving gear two 34 meshes and drives the driving gear one 33, and then the driving gear one 33 meshes and drives the rack bar 15, so that the roller ones 24, the roller twos 26, the roller threes 31, and the roller fours 32 are rollingly arranged in the track assembly. A roller five 37 is provided at the bottom of the driving gear one 33. The roller five 37 is slidably arranged with the track assembly.

[0030] The specific sliding connection method is as follows: The first rail surface on the inner surface of the first rail plate 11 is rollingly installed with the roller one 24. The second rail surface on the outer surface of the first rail plate 11 is rollingly installed with the roller two 26. The second rail 13 is rollingly installed with the roller three 31. The first rail 6 is rollingly installed with the roller four 32. The third rail surface on the inner side of the second skateboard 3 is rollingly installed with the roller five 37.

[0031] The specific installation direction of the rollers on the track or rail surface is as follows: The axis of the roller three 31 is perpendicularly arranged with the axis of the second skateboard 3. The axes of the roller one 24, the roller two 26, the roller four 32, and the roller five 37 are all parallel to the axis of the second skateboard 3, which can realize the rolling of the rolling component in the track assembly along two directions of horizontal and vertical, meet the stability of the rolling motion, and realize the movement along a specific braiding track.

[0032] The specific usage method of the cycloid limit component 1 is as follows: As Figure 1 , 2As shown in Figures 5 and 6, a cycloid component is installed at the bottom of the cycloid limit component 1. The side of the cycloid component close to the axis direction of the second slide plate 3 is set as the driving cam 36. The upper cycloid rod 35 of the cycloid component realizes the up and down swinging of the cycloid rod 35 through the driving of the driving cam 36. Specifically: when the long side of one side of the driving cam 36 meshes with the motor driving component, the cycloid rod 35 swings slowly upward within the accommodating long strip opening 14. As the driving cam 36 continues to rotate and meshes with the motor driving component through the short side of one side, the cycloid rod 35 quickly swings out of the accommodating long strip opening 14. When the long side of the other side of the driving cam 36 meshes with the motor driving component, the cycloid rod 35 swings slowly downward and swings into the accommodating long strip opening 14. When the short side of the other side meshes with the motor driving component, the cycloid rod 35 in the downward position quickly swings out of the accommodating long strip opening 14. When the long side of one side meshes with the motor driving component again, the cycloid rod 35 swings slowly upward and returns to the accommodating long strip opening 14. Thus, the up and down swinging trajectory of a unit of the spindle wire feeding is formed. When the spindle wire feeding rotates with the long side meshing, the wire is fed along the horizontal line trajectory. When the short side meshes and rotates, the spindle wire feeding is fed along the vertical direction trajectory. The overall trajectory forms a trapezoidal structure trajectory for wire feeding. However, the vertical direction trajectory is much smaller than the horizontal wire feeding trajectory length. Therefore, the spindle wire feeding trajectory is approximately the horizontal wire feeding trajectory, enabling the spindles to rotate along the concentric trajectory with a small trajectory operation range, improving the wire outlet speed, being more in line with the spindle operation law, improving the knitting quality and knitting efficiency, and solving the problems of large swing amplitude, slow knitting efficiency, and poor compactness in the traditional cycloid positive rotation trajectory; reducing the noise generated by the impact of the slider and the knitting movement trajectory in the prior art, as well as the wear between the slider and the trajectory, achieving the purpose of concentric wire feeding, reducing the space of the operation trajectory, and improving the knitting wire outlet speed.

[0033] The embodiments in the present invention are only used to illustrate the present invention and do not constitute a limitation on the scope of the claims. Other substantially equivalent alternatives that can be thought of by those skilled in the art are all within the protection scope of the present invention.
