Description

Technical Field

[0001] This utility model relates to the field of zipper processing equipment, specifically a small winding device for the upper and lower stop wires of a zipper. Background Technology

[0002] Zipper top and bottom thread is a key raw material in zipper production, and its winding quality directly affects the precision of subsequent processing and product quality. In the zipper manufacturing industry, thread winding must meet the requirements of neatness, compactness, no overlapping threads, and no skipping grooves to ensure the stability of subsequent processes such as unwinding, cutting, and forming. Therefore, the performance of the winding device has a significant impact on thread processing efficiency and finished product quality.

[0003] Currently, there are still many shortcomings in the practical application of winding devices for zipper top and bottom stop wires. In terms of winding neatness, the winding components of existing winding devices mostly only perform a single rotational motion. The arrangement of the wire on the winding drum mainly relies on the wire's own tension or simple guidance, which easily leads to problems such as concentrated wire accumulation and uneven spacing. This results in loose wire rolls with uneven end faces after winding, which not only takes up more storage space, but may also affect the continuity of processing due to messy wire tangling in subsequent use.

[0004] Regarding the adaptability of the wire guide angle, as the thickness of the wire on the take-up spool increases layer by layer during the winding process, the outer diameter of the spool continuously increases, and the angle at which the wire enters the take-up spool gradually changes. The wire guide mechanism of existing winding devices is usually in a fixed position, and the height difference and angle between the wire entry point and the take-up point will change significantly. It is impossible to adjust the position in real time according to the winding thickness. When the winding thickness increases to a certain extent, the deviation of the included angle between the wire and the take-up spool increases, which can easily lead to increased wire tension fluctuations and increased friction, which can easily cause wire skipping and breakage. It also makes it difficult to accurately lay the wire in the predetermined position, resulting in loose winding, uneven edges, and even bulging or collapsed edges.

[0005] Regarding winding stability, the transition section from the yarn guide mechanism to the take-up drum lacks effective guidance. At the moment of final entry into the take-up point, the yarn is prone to lateral swaying or deviation due to factors such as equipment vibration and yarn tension fluctuations. This swaying can cause positional deviation of the yarn at the moment of winding, resulting in phenomena such as yarn overlap, skipping, or even yarn wear, seriously affecting the winding quality. Traditional guiding methods such as yarn guide rollers and yarn hooks are not effective in suppressing this subtle, high-frequency vibration because their guide points are still a certain distance from the take-up point and their constraint direction is limited. This makes it difficult to ensure accurate positioning of the yarn at the moment of winding, affecting the tightness and flatness of the winding. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the prior art by providing a small winding device for the upper and lower stop wires of zippers, which solves the problems of insufficient winding neatness, poor adaptability of the wire passing angle, and low winding stability.

[0007] The technical solution of this utility model includes a take-up mechanism, a guide roller mechanism, and a guide mechanism. The take-up mechanism includes a rotating shaft capable of linear reciprocating motion and a take-up drum detachably and fixedly sleeved on the rotating shaft. The guide roller mechanism is located on the inlet side of the take-up drum and is used to guide the wire introduced into the guide roller mechanism to the take-up drum. A lifting component is also connected to the guide roller mechanism, which drives the guide roller mechanism to gradually rise in the vertical direction. The guide mechanism is fixedly installed on the guide roller mechanism and located between the guide roller mechanism and the take-up drum. The guide mechanism includes two bow arms arranged at intervals and opposite to each other and at least two strings tensioned between the two bow arms. The two strings are arranged in parallel at intervals to form a guide channel for the wire to pass through. The guide channel is arranged perpendicular to the take-up drum and is located at the position where the wire is about to be wound into the take-up drum. The wire is introduced through the guide roller mechanism, passes between the two strings, and is finally wound into the take-up drum.

[0008] By adopting the above technical solution, the rotating shaft of the take-up mechanism is designed to simultaneously rotate and reciprocate linearly, achieving an orderly arrangement of the wire first being laid out in one layer on the take-up drum and then wound layer by layer. This solves the problems of wire accumulation and uneven gaps caused by the single rotational motion of traditional take-up devices, improving the neatness of the winding. The lifting component drives the wire guide roller mechanism to rise with the winding thickness, dynamically adapting to changes in the wire winding angle, avoiding tension fluctuations and instability of the roll caused by angle deviations in the fixed-height wire guide mechanism. The double-chord guide channel of the guide mechanism is set at a key position before winding, forming a precise constraint on the wire, effectively suppressing the lateral swaying of the wire before winding, solving the problems of wire stacking and skipping caused by insufficient constraint in traditional guide methods, and improving the overall winding stability and roll quality.

[0009] In one possible design, a fixing member and a winding post are installed on the bow arm. The end of the string is fixedly connected to the fixing member of one bow arm, extends from the fixing member through the winding post on the same side of the bow arm, and then extends to the winding post and fixing member on the other bow arm, and is finally fixed to the fixing member of the other bow arm. Multiple spaced mounting holes are provided on the bow arm, and the fixing member and / or winding post can be detachably and selectively fixed to any one of the mounting holes.

[0010] With the above design, when dealing with wires of different characteristics, the tension, spacing and installation angle of the chord can be flexibly adjusted by selecting different mounting hole positions, so that the guide channel is always in a taut state, avoiding guide failure due to chord slack. It can quickly adapt to wires of different characteristics, improving the versatility of the equipment and the ease of operation.

[0011] In one possible design, the lifting assembly includes a vertically arranged lifting screw and a lifting drive component that drives the lifting screw to rotate. The wire guide roller mechanism is connected to the lifting screw in a transmission connection, so that when the lifting screw rotates, it can drive the wire guide roller mechanism to gradually rise in the vertical direction.

[0012] The above design employs a transmission structure consisting of a lifting screw and a lifting drive component, enabling the lifting action of the wire guide roller mechanism to have stable linear adjustment characteristics. Compared to traditional pneumatic or hydraulic lifting methods, the screw drive can achieve millimeter-level precision height control, ensuring that the lifting speed of the wire guide roller mechanism is strictly matched with the winding thickness growth rate, accurately maintaining the consistency of the wire winding angle, solving the problem of winding angle deviation caused by insufficient adjustment precision of traditional lifting mechanisms, and ensuring the uniformity of force during the layer-by-layer thickening process of the roll.

[0013] In one possible design, the take-up mechanism also includes a transverse lead screw, a transverse drive for driving the transverse lead screw to rotate, a rotation drive for driving the shaft to rotate, and a proximity sensor. The proximity sensor is located near the start and end points of the axial movement path of the rotation drive and is electrically connected to the transverse drive to send a reverse switching signal to the transverse drive when the proximity sensor detects that the rotation drive has reached the start or end point.

[0014] By adopting the above design, the automatic reversing control of the axial reciprocating motion of the shaft is realized through the signal connection between the proximity sensor and the transverse drive. When the drive reaches the start or end of the stroke, the proximity sensor triggers a reversing signal in real time, avoiding the impact vibration of the traditional mechanical reversing structure, making the linear reciprocating motion of the shaft smoother, and further improving the uniformity of wire arrangement and winding stability.

[0015] In one possible design, the wire guide roller mechanism includes a lifting base plate, an inlet roller, and an outlet roller. The inlet roller and outlet roller are rotatably mounted on the lifting base plate, and two bow arms are fixedly connected to the lifting base plate and are respectively located on both sides of the width of the lifting base plate.

[0016] The above design extends the guide path of the wire in the guide roller mechanism by combining the inlet roller and outlet roller, pre-constraining the wire and reducing the swaying of the wire before it enters the guide mechanism. The inlet roller, outlet roller, and bow arm are integrated into the lifting base plate to ensure that all guide components rise and fall synchronously, maintaining the vertical alignment between the chord channel and the take-up drum. The bow arms are placed on both sides of the lifting base plate to form a stable triangular support, preventing chord drift caused by winding vibration and consolidating the reliability of near-end guidance.

[0022] like Figures 1 to 4 The illustrated small winding device for zipper top and bottom stop wires mainly includes a winding mechanism 1, a wire guide roller mechanism 2, and a guiding mechanism 4. These three components work together to achieve neat and stable winding of the wire 5. The winding mechanism 1 is located at the winding end of the device and is used to wind and store the wire 5. The wire guide roller mechanism 2 is located on the wire inlet side of the winding mechanism 1 and undertakes the guiding and conveying function of the wire 5. The guiding mechanism 4 is fixed to the wire guide roller mechanism 2 and is actually located between the wire guide roller mechanism 2 and the winding mechanism 1, providing precise constraint on the wire 5 to be wound. A lifting assembly 3 is connected to the wire guide roller mechanism 2 and drives it to dynamically rise and fall with the winding thickness, ensuring a stable winding angle.

[0023] The take-up mechanism 1 includes a rotating shaft 11, a take-up drum 12, a transverse lead screw 13, a transverse drive component, a rotation drive component 14, and a proximity sensor. The rotating shaft 11 adopts a stepped shaft structure, and one end of it is connected to the output shaft of the rotation drive component 14 (such as a servo motor) via a coupling. The rotation drive component 14 can drive the rotating shaft 11 to rotate around its own axis, thereby realizing the winding action of the take-up drum 12. The take-up drum 12 is detachably and fixedly connected to the rotating shaft 11 through a fixed structure (such as a keyway), which facilitates quick replacement of the empty drum after winding is completed.

[0024] The bottom of the rotary drive component 14 is threaded into the transverse lead screw 13, and the bottom of the rotary drive component 14 can also slide horizontally via a guide rail. The transverse lead screw 13 is horizontally positioned, and its end is connected to the transverse drive component (such as a stepper motor). When the transverse drive component is working, the transverse lead screw 13 drives the rotary drive component 14 to drive the rotating shaft 11 to make linear reciprocating motion along the axial direction, so that the wire 5 is laid layer by layer on the take-up drum 12. There are two proximity sensors, which are respectively installed at the frame positions corresponding to the start and end points of the axial movement path of the rotary drive component 14, and are electrically connected to the transverse drive component via wires. When the rotary drive component 14 moves with the rotating shaft 11 to the start or end point, the proximity sensor detects the signal and sends it to the transverse drive component. The transverse drive component immediately switches the direction, realizing shock-free reversal of the reciprocating motion of the rotating shaft 11, ensuring that the wire 5 is evenly distributed.

[0025] The wire guide roller mechanism 2 includes a lifting base plate 21, an inlet roller 22, and an outlet roller 23. The lifting base plate 21 is a rectangular steel plate, serving as the mounting base for the wire guide roller mechanism 2. Its bottom is slidably engaged with the vertical guide rail on the frame via a slider. The inlet roller 22 and the outlet roller 23 are arranged parallel and spaced apart. Both ends of the rollers are rotatably mounted on the top surface of the lifting base plate 21 via bearing seats, and their axes are parallel to the axis of the take-up drum 12. The wire 5 is wound around the inlet roller 22 from above, passes through the gap between the inlet roller 22 and the outlet roller 23, and then exits from below the outlet roller 23, forming an "S"-shaped guide path, extending the guide stroke to stabilize the posture of the wire 5.

[0026] The lifting assembly 3 is connected to the lifting base plate 21, and specifically includes a lifting screw 31 and a lifting drive component 32. The lifting screw 31 is vertically arranged, with its lower end fixed to the frame via a bearing seat, and its upper end connected to the output shaft of the lifting drive component 32 (such as a geared motor). A nut seat is fixed on the lifting base plate 21, and the nut seat is threadedly engaged with the lifting screw 31. When the lifting drive component 32 drives the lifting screw 31 to rotate, the nut seat drives the lifting base plate 21 to rise and fall smoothly along the vertical guide rail, thereby driving the entire winding roller mechanism 2 to rise synchronously, realizing dynamic adaptation between the winding height and the winding thickness.

[0027] The guiding mechanism 4 includes two bow arms 41, a string 42, a fixing member 43, and a winding post 44. The two bow arms 41 are arc-shaped steel plates, respectively located on both sides of the lifting base plate 21 in the width direction, with the arc-shaped opening formed by the two bow arms 41 facing the take-up drum 12. Each bow arm 41 has multiple mounting holes 411, which are evenly spaced along the arrangement direction of the bow arms 41.

[0028] The fixing member 43 is a threaded cylindrical structure, and the winding post 44 is a cylinder. Both are detachably installed in the mounting hole 411 by bolts. The string 42 is made of high-strength nylon thread or steel wire. One end is fixed to the fixing member 43 of one bow arm 41, and after passing through the winding post 44 of the same bow arm 41 and the winding post 44 of the other bow arm 41 in sequence, the other end is fixed to the fixing member 43 of the other bow arm 41. The string 42 can be tensioned by tightening the fixing member 43 or adjusting the position of the winding post 44. The winding post 44 is a cylinder with a soft surface or a surface with several spaced grooves. When the string 42 passes through the soft surface of the winding post 44, it will be scraped into the soft layer, or the string 42 will enter the corresponding groove, thereby restricting the position of the string 42. In this embodiment, two strings 42 are provided, which are arranged in parallel and spaced apart to form a guide channel 421 with adjustable width. The guide channel 421 is perpendicular to the axis of the take-up drum 12 and is located at or near the position where the wire 5 is about to be wound into the take-up drum 12.

[0029] The working process of this device is as follows:

[0030] In use, the empty take-up spool 12 is fixed on the rotating shaft 11. The spacing and tension of the string 42 of the guiding mechanism 4 are adjusted according to the specifications such as the diameter and physical characteristics of the wire 5. By selecting different positions of the mounting holes 411, the fixing piece 43 and the winding post 44 are moved so that the spacing of the double string 42 is slightly larger than the diameter of the wire 5, ensuring that the wire 5 can pass through smoothly without obvious shaking. In addition, the double string 42 is kept in a taut state to ensure that there is enough tension to guide the wire 5.

[0031] After the device is started, the wire 5 is introduced sequentially through the inlet roller 22 and the outlet roller 23, then passes through the guide channel 421 formed by the double chord 42, and finally reaches the take-up drum 12. The rotation drive 14 drives the rotating shaft 11 to rotate, which in turn drives the take-up drum 12 to wind the wire 5; at the same time, the transverse drive drives the transverse lead screw 13 to rotate, so that the rotating shaft 11 makes a linear reciprocating motion along the axial direction. The wire 5 is first laid on the take-up drum 12 in one layer, and then wound up layer by layer with the reciprocating motion of the rotating shaft 11.

[0032] As the winding thickness increases, the lifting drive 32 drives the lifting screw 31 to rotate, causing the wire guide roller mechanism 2 to gradually rise, thus maintaining a stable winding angle for the wire 5. When the rotation drive 14 moves to the start or end of its stroke, the proximity sensor triggers a signal, and the lateral drive switches its direction, achieving a smooth reversal of the shaft 11. The double-chord line 42 of the guide mechanism 4 always constrains the wire 5, suppressing swaying before winding and ensuring precise arrangement of the wire 5.

[0033] This implementation method effectively solves the problems of insufficient winding neatness, poor adaptability of thread passing angle, and low winding stability through the coordinated cooperation of various mechanisms, and is suitable for efficient winding operations of various zipper upper and lower stop wires 5.
