Description

Technical Field

[0001] This application relates to the technical field of metal wire processing equipment, specifically to a double-layer V-shaped reel take-up device. Background Technology

[0002] In continuous production lines for metal wire, winding, as the final and crucial step, often requires coiling wire into spools of varying diameters to meet the demands of different product specifications. Inverted winding machines are widely used because they can produce shaftless, large, and heavy spools, facilitating subsequent packaging, transportation, and unwinding. Currently, most inverted winding machines on the market employ a single-layer traction reel structure. This single-layer structure limits its adaptability to different spool diameters. To wind larger or smaller spools, the entire traction reel assembly needs to be replaced, which is not only cumbersome but also time-consuming and labor-intensive.

[0003] To wind up spools of different diameters, Chinese Patent Publication No. CN216426339U discloses a galvanized steel wire drop-type winding device. This device uses multiple traction spools coaxially fixed to form a traction spool assembly. By selectively winding the steel wire onto traction spools of different diameters, winding up spools of varying diameters can be achieved. While this patent's technical solution enables winding up spools of different diameters, its wire feeding method—where the steel wire must pass from top to bottom through a long, rotating hollow shaft that runs through the entire multi-layered traction spool assembly, reaching the guide wheel system at the bottom of the device, and then turning back upwards to guide it to the target traction spool—makes the wire feeding process cumbersome. Furthermore, the high-speed passage of the steel wire through the narrow inner wall of the hollow shaft may scratch the coating or drawing film on the wire surface, affecting the final product quality. Furthermore, during the actual winding process, due to the difference in the diameter of the traction reels of different diameters, the mismatch in the straightening and guiding angles of the wire before entering different traction reels can easily cause uneven reel diameters in the finished winding product, resulting in a "winding" phenomenon, which affects the overall quality and stability of the reel. Utility Model Content

[0004] The purpose of this invention is to provide a double-layer V-shaped reel take-up device, which can significantly improve the take-up equipment's ability to quickly switch between reels of different specifications and the stability of take-up quality.

[0005] This application is achieved through the following technical solution, specifically:

[0006] A double-layer V-shaped reel take-up device includes a frame, a frequency converter drive assembly disposed on the upper end of the frame, a traction reel connected to the lower end of the frequency converter drive assembly, a take-up frame disposed directly below the traction reel, and a guide wheel assembly mounted on the frame. The traction reel includes an upper traction reel and a lower traction reel coaxially arranged, the diameter of the upper traction reel being larger than the diameter of the lower traction reel. The guide wheel assembly includes a multi-stage guide wheel group disposed on the side of the traction reel and a wire inlet straightener disposed between the multi-stage guide wheel group and the traction reel, the mounting height of the wire inlet straightener on the frame being adjustable.

[0007] In this solution, the synergistic design of a double-layer traction disc structure and an adjustable straightening guide wheel assembly significantly improves the take-up equipment's ability to quickly switch between different spool sizes and enhances the stability of take-up quality. Specifically, the upper and lower traction discs adopt a coaxial, V-shaped layered layout with the upper one being larger than the lower one. This allows the wire to be directly selected to enter different diameter traction discs according to the target spool diameter requirements, without the need to replace the traction disc assembly or rely on a long threading path through the hollow shaft. This avoids scratches on the plating caused by high-speed friction between the wire and the inner wall of the hollow shaft, while also simplifying the threading operation. Furthermore, the multi-stage guide wheel assembly located on the side of the traction disc, combined with an adjustable-height wire straightener, dynamically matches the diameter differences of different traction discs by adjusting the straightener's installation height. This ensures that the wire maintains a consistent straightening angle and tension distribution before entering the traction disc, eliminating localized stress concentration or wire stacking misalignment caused by deviations in the guiding angle of wires with different spool diameters, thereby overcoming the "winding" phenomenon.

[0008] As an improvement to the infeed straightener in this application, the infeed straightener is connected to the frame via a lifting bracket, the lifting bracket including a slide groove and a locking member that cooperates with the slide groove.

[0009] Furthermore, the side of the chute is provided with at least two positioning holes at intervals, and positioning pins are installed in the positioning holes. The positioning pins include a first positioning pin corresponding to the take-up path of the upper traction disc and a second positioning pin corresponding to the take-up path of the lower traction disc.

[0010] As an improvement to the multi-stage guide wheel assembly in this application, the multi-stage guide wheel assembly includes an infeed guide wheel assembly and a steering guide wheel assembly mounted on the upper side of the frame, a first guide wheel and a second guide wheel mounted on the top of the frame, wherein the rotating shaft of the second guide wheel is inclined downward relative to the plane of the traction disc.

[0011] Furthermore, the steering guide wheel assembly includes an adjustment handwheel and a plurality of guide wheels, the handwheel being used to control the relative positions of the plurality of guide wheels.

[0012] Furthermore, the multi-stage guide wheel assembly also includes a third guide wheel disposed in the infeed guide wheel assembly and the steering guide wheel assembly, the third guide wheel being used to adjust the wire height.

[0013] As an improvement to the variable frequency drive assembly in this application, the variable frequency drive assembly includes a drive motor and a reducer connected to the output end of the drive motor, wherein the output shaft of the reducer is connected to the traction disc.

[0014] The beneficial effects of this application are as follows:

[0015] This application's solution effectively solves the problems of poor disc diameter adaptability, wire surface damage, and uneven winding in existing technologies through the synergistic design of a double-layer traction disc structure and an adjustable straightening guide wheel assembly. Specifically, the upper and lower traction discs adopt a coaxial, V-shaped layered layout with the upper one being larger than the lower one. This allows the wire to directly enter different diameter traction discs according to the target disc diameter requirements, without the need to replace the traction disc assembly or rely on a long threading path through the hollow shaft. This avoids plating scratches caused by high-speed friction between the wire and the inner wall of the hollow shaft, while simplifying the threading operation. The multi-stage guide wheel assembly located on the side of the traction disc, combined with an adjustable-height wire straightener, dynamically matches the diameter differences of different traction discs by adjusting the installation height of the straightener. This ensures that the wire maintains a consistent straightening angle and tension distribution before entering the traction disc, eliminating local stress concentration or wire stacking misalignment caused by deviations in the guiding angle of wires with different disc diameters, thereby overcoming the "winding" phenomenon.

[0022] The following will be combined with the appendix Figures 1-3 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] In view of the problems existing in the background technology or products, Figure 1 This paper shows a schematic diagram of the structure of a double-layer V-shaped reel take-up device according to an embodiment of this application. Figure 2 This illustration shows a partial structural diagram of a double-layer V-shaped reel take-up device according to an embodiment of this application. Figure 3 A partially enlarged view of the feed line straightener in an embodiment of this application is shown. For example... Figure 1-3 As shown, this application embodiment provides a double-layer V-shaped reel take-up device, including a frame 1, a frequency converter drive assembly 2 disposed on the upper end of the frame 1, a traction disc 3 connected to the lower end of the frequency converter drive assembly 2, a take-up frame 4 disposed directly below the traction disc 3, and a guide wheel assembly 5 mounted on the frame 1.

[0024] The traction disc 3 includes an upper traction disc 31 and a lower traction disc 32 coaxially arranged, the diameter of the upper traction disc 31 being larger than the diameter of the lower traction disc 32; the guide wheel assembly 5 includes a multi-stage guide wheel group disposed on the side of the traction disc 3 and a line straightener 51 disposed between the multi-stage guide wheel group and the traction disc 3, the mounting height of the line straightener 51 on the frame 1 being adjustable.

[0025] Specifically, the variable frequency drive assembly 2 includes a drive motor 21 and a reducer 22 connected to the output end of the drive motor 21. The output shaft of the reducer 22 is connected to the traction disc 3. The output shaft of the reducer 22 is vertically connected to the rotating shaft of the traction disc 3 via a coupling. The traction disc 3 consists of an upper traction disc 31 and a lower traction disc 32 coaxially welded together to form a stepped double-layer V-shaped structure. When it is necessary to wind spools of different diameters, the wire can be selectively fed into the upper traction disc 31 or the lower traction disc 32 according to the target spool diameter requirement. Through this simple selective winding operation, the production switching between two different specifications of spools can be conveniently achieved without changing any hardware components, significantly improving the adaptability and working efficiency of the equipment.

[0026] A multi-stage guide wheel assembly is located on the side of the traction disc 3, guiding the wire from the side of the frame 1 towards the traction disc 3. The wire straightener 51 is positioned between the multi-stage guide wheel assembly and the traction disc 3, and its installation height on the frame 1 is adjustable. When the take-up target is switched to the upper traction disc 31 or the lower traction disc 32, which have different diameters and spatial heights, adjusting the installation height of the wire straightener 51 allows its outlet to match the winding plane of the currently used traction disc. This ensures that the metal wire always enters the traction disc in a straightened and stable posture, eliminating the wire inlet angle deviation caused by traction disc switching. Combined with the variable frequency drive assembly 2's variable frequency speed control, this ensures a uniform diameter of the finished take-up disc, prevents wire winding, and improves the overall quality and stability of the wire disc.

[0027] In one implementation, the incoming line straightener 51 is connected to the frame 1 via a lifting bracket 6, the lifting bracket 6 including a slide groove 61 and a locking member 62 that cooperates with the slide groove 61.

[0028] Specifically, the chute 61 is a straight slot extending along the height direction of the lifting bracket 6, providing a stable vertical movement path for the wire straightener 51. The length of the chute 61 covers the vertical distance between the wire entry points of the upper traction plate 31 and the lower traction plate 32, with a certain margin reserved. The locking member 62 is a device that cooperates with the chute 61 to fix the wire straightener 51 at a specific height position. The locking member 62 can have various specific implementations, such as bolt-nut locking, spring pin locking, etc.

[0029] Preferably, the side of the chute 61 is provided with at least two positioning holes at intervals, and positioning pins 63 are installed in the positioning holes. The positioning pins 63 include a first positioning pin 631 corresponding to the take-up path of the upper traction disc 31 and a second positioning pin 632 corresponding to the take-up path of the lower traction disc 32. By using the positioning pins 63 corresponding to different traction discs, the position of the wire feed straightener 51 can be quickly adjusted to ensure that it matches the take-up path of traction discs 3 of different diameters, and to avoid wire damage or uneven take-up caused by positional deviation of the wire feed straightener 51.

[0030] In one implementation, the multi-stage guide wheel assembly includes an infeed guide wheel assembly 52 and a steering guide wheel assembly 53 mounted on the upper side of the frame 1, a first guide wheel 54 and a second guide wheel 55 mounted on the top of the frame 1, wherein the shaft of the second guide wheel 55 is inclined downward relative to the plane of the traction disc 3.

[0031] Specifically, the feed guide roller assembly 52 is installed on the upper side of the frame 1, consisting of several horizontally arranged guide rollers, used to initially guide the wire from the wire supply source (such as the wire feeding frame). These guide rollers can be made of different materials and have different surface treatments depending on the diameter and hardness of the wire, in order to reduce the coefficient of friction and protect the surface of the wire. The steering guide roller assembly 53 is also installed on the upper side of the frame 1, located after the feed guide roller assembly 52. ​​The main function of the steering guide roller assembly 53 is to turn the wire's travel direction one or more times according to the overall layout of the take-up device and the relative position of the traction disc 3, gradually adjusting the wire from the feed direction along the side wall of the frame 1 to the tangential direction of the traction disc 3. Preferably, the steering guide roller assembly 53 includes an adjustment handwheel 531 and multiple guide rollers 532, wherein the handwheel 531 is used to control the relative position of the multiple guide rollers 532. After the wire reaches the top, it passes through the traction disc 3, the first guide wheel 54 and the wire straightener 51 in sequence, and then enters the traction disc 3 at a suitable angle and tension. After the wire passes out of the traction disc 3, it is slowly lowered onto the take-up frame 4 through the second guide wheel 55, which is set at an angle and downward.

[0032] Preferably, the multi-stage guide wheel assembly further includes a third guide wheel 56 disposed on the infeed guide wheel assembly 52 and the steering guide wheel assembly 53. The third guide wheel 56 is used to adjust the wire height. In actual production applications, the conveying height of the metal wire from the previous process may vary due to differences in production line layout. By setting a third guide wheel 56 that can be finely adjusted in position, the initial height can be calibrated in advance before the wire enters the main steering and lifting path. This effectively avoids unnecessary bending of the wire, abnormal friction with the guide wheel sidewall, or tension fluctuations that may be caused by a poor initial entry angle, ensuring a smooth transition of the entire guiding path.
