Description

Technical Field

[0001] This invention relates to the technical field of wire winding, and in particular to a wire winding switching structure and winding machine. Background Technology

[0002] Steel wire is an indispensable basic material in modern industry, and is widely used in the manufacture of tire cords, bridge cables, automotive parts and other metal products. On the production lines in these fields, steel wire needs to be wound at high speed and continuously onto spools such as I-beams for storage, transportation and subsequent processing.

[0003] In traditional wire winding operations, a single-station winding mode is commonly used. When the length of wire wound on a specific spool reaches the predetermined specification, the entire winding process must be interrupted. Operators need to perform a series of operations, such as stopping the machine, cutting the wire, unloading the full spool, replacing the empty spool, and fixing it back onto the new spool, before finally restarting the equipment and resuming production. This repetitive operation mode has become an inherent part of high-speed continuous production processes.

[0004] This traditional single-reel winding operation mode severely restricts the improvement of production efficiency because it cannot perform continuous winding operations. At the same time, its operation is cumbersome, requires a lot of manpower, and has a low degree of automation. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a wire winding switching structure and a winding machine, the specific technical solution of which is as follows:

[0006] The present invention provides a wire winding switching structure, comprising an adjustment disk that rotates on a horizontal plane and a plurality of columns distributed circumferentially around the axis of the adjustment disk, wherein a horizontal axis is provided between two adjacent columns, and each horizontal axis is provided with a spool for winding the wire.

[0007] A drive wheel is provided at both ends of the horizontal shaft, and the two drive wheels on the column are connected to each other for transmission. A cutting unit for cutting steel wire is provided on the column.

[0008] Furthermore, the horizontal axis is composed of two coaxial but separate sub-axis, the reel is composed of two sub-reels joined together, and the sub-reels can slide on the corresponding sub-axis.

[0009] Furthermore, a plurality of locking blocks and a rotating ring are provided on the outer wall of the split shaft. The transmission wheel is located at one end of the split shaft, and a plurality of locking blocks are located at the other end of the split shaft. The plurality of locking blocks are distributed around the circumference of the split shaft. The locking blocks are conical in shape and their direction is towards the transmission wheel. The rotating ring is rotatably connected to the split shaft. A plurality of elastic bodies connected to the corresponding split discs are provided on the outer wall of the rotating ring.

[0010] The inner wall of the partition is provided with several slots that cooperate with each of the card blocks, and the docking positions of the two partitions are provided with several inserts and several slots that cooperate with each other.

[0011] Furthermore, a protective cover is provided on the split shaft to isolate the rotating ring and the elastomer. The protective cover is slidably disposed on the split shaft and is connected to the split disc.

[0012] Furthermore, several right-angle hooks are provided on the retaining edges on both sides of the spool.

[0013] Furthermore, the cutting unit includes a movable ring slidably disposed on the column and a cutting groove formed on the side wall of the column along the length direction of the column. An inclined arm and a cutting tool are rotatably disposed on the movable ring and in the cutting groove, respectively. The inclined arm and the cutting tool are rotatably connected to each other, and the cutting tool is used in conjunction with the cutting groove.

[0014] Furthermore, a sliding column is provided on the outer wall of the movable ring;

[0015] The switching structure also includes an outer ring located outside the plurality of columns and fixedly installed. The inner wall of the outer ring is provided with an annular groove that cooperates with the sliding column. The annular groove is composed of an arc groove and a V-groove.

[0016] A wire winding machine includes the aforementioned wire winding switching structure, and further includes a wire feeding structure for carrying and releasing the wire, a straightening structure for straightening the wire, a tension control structure for adjusting the wire winding tension, a wire laying structure for neatly arranging the wire, and a spreading structure for separating the two spools on the wire reel.

[0017] The beneficial effects of this invention are as follows:

[0018] By utilizing the rotation of the regulating disc, several reels on it are sequentially transferred to the winding station, allowing the steel wire to be wound onto each reel in turn. This enables automatic switching of the reels, ensuring continuous steel wire conveying and greatly improving the continuity of steel wire winding, increasing work efficiency, and avoiding the cumbersome operation of frequently changing reels in traditional methods, thus achieving an automated switching work mode.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0032] like Figures 1 to 7 As shown, a wire winding switching structure of the present invention includes an adjustment disk 1 that rotates on a horizontal plane and several columns 2 distributed around the axis of the adjustment disk 1. A horizontal axis 3 is provided between two adjacent columns 2, and a wire spool 4 for winding the wire is provided on each horizontal axis 3.

[0033] A drive wheel 5 is provided at both ends of the horizontal shaft 3, and the two drive wheels 5 on the column 2 are connected to each other for transmission. A cutting unit 6 for cutting the steel wire is provided on the column 2.

[0034] In this invention, several horizontal shafts 3 form a polygon, and several wire reels 4 on them are also distributed in a polygonal pattern. Thus, when one wire reel 4 is in the working state of winding steel wire, other wire reels 4 can be in positions such as transferring steel wire, bundling steel wire rolls, unpacking steel wire rolls, and cleaning, so that each position corresponding to each wire reel 4 can have a specific function, improving the functionality of the overall structure. The axis of the adjusting disc 1 is vertical, and the adjusting disc 1 can be supported by several columns 2 on several horizontal shafts 3 and several wire reels 4. When the adjusting disc 1 rotates, it will drive several wire reels 4 to move synchronously, thereby allowing several wire reels 4 to move sequentially between different positions. Since adjacent horizontal shafts 3 are mutually transmitted through two transmission wheels 5, several horizontal shafts 3 and several wire reels 4 can rotate synchronously and in the same direction. Thus, only one motor is needed to drive any horizontal shaft 3 to rotate, which can provide power to several wire reels 4.

[0035] In operation, several horizontal shafts 3 and several wire reels 4 rotate synchronously. The wire reel 4 at the winding station performs wire winding. When the wire winding length on the wire reel 4 reaches the specified value, the adjusting disc 1 is rotated to move the wire reel 4 away, and the next wire reel 4 is transferred to the winding station. Since several wire reels 4 rotate synchronously in the same direction, the wire can be directly transferred from one wire reel 4 to another wire reel 4, realizing a smooth transition of the wire between different wire reels 4. The wire reel 4 at the winding station continues to wind the wire, thus realizing a smooth switching of wire reels 4. Moreover, the rotation of several wire reels 4 and the feeding of wire can be carried out continuously without stopping the machine.

[0036] It should be noted that, due to the presence of the column 2, when the wire is transferred from one spool 4 to another, the wire section between two adjacent spools 4 will be blocked by the column 2. At this time, the wire section between the two adjacent spools 4 can be cut by the cutting unit 6 on the column 2, thereby avoiding interference between the column 2 and the wire and fixing the wire end on the empty spool 4. As the spool 4 rotates, the wire can be smoothly wound and coiled. To fix the wire end, a movable arm or pressure plate driven by a cylinder can be set on each spool 4. The wire end can be pressed onto the spool 4 using this structure.

[0037] By rotating the adjusting disc 1, several coils 4 on it are sequentially transferred to the winding station, so that the steel wire can be wound onto each coil 4 in sequence. This achieves automatic switching of the coils 4, ensuring continuous steel wire conveying, greatly improving the continuity of steel wire winding, increasing work efficiency, and avoiding the cumbersome operation of frequently changing coils 4 in the traditional method, thus realizing an automated switching working mode.

[0038] Furthermore, the horizontal axis 3 is composed of two coaxial but separate sub-axis 7, and the coil 4 is composed of two sub-coils 8 joined together, and the sub-coils 8 can slide on the corresponding sub-axis 7.

[0039] Once the wire winding length on the reel 4 reaches the specified requirement, the wire roll needs to be removed from the reel 4. To facilitate operation, a combination method can be used, namely, the two sub-shafts 7 combined with the horizontal shaft 3, and the two reels 8 combined with the reel 4. The two reels 8 are separated from each other and slide on the corresponding sub-shafts 7. The wire roll located between the two reels 8 can be moved away through the original gap between the two sub-shafts 7, thus allowing the wire roll to be removed directly, improving convenience.

[0040] Furthermore, a number of locking blocks 9 and a rotating ring 10 are provided on the outer wall of the split shaft 7. The transmission wheel 5 is located at one end of the split shaft 7, and the number of locking blocks 9 are located at the other end of the split shaft 7. The number of locking blocks 9 are distributed around the circumference of the split shaft 7. The shape of the locking blocks 9 is conical, and their direction is towards the transmission wheel 5. The rotating ring 10 is rotatably connected to the split shaft 7. A number of elastic bodies 11 connected to the corresponding split discs 8 are provided on the outer wall of the rotating ring 10.

[0041] On the inner wall of the sub-disc 8, there are several slots 12 that cooperate with each card block 9. At the docking position of the two sub-discs 8, there are several inserts 13 and several slots 14 that cooperate with each other.

[0042] Since the two split shafts 7 are separated from each other, and the two split disks 8 need to be connected, in the natural state, the locking block 9 on the split shaft 7 needs to be located inside the split disk 8 near the outer wall of the split disk 8, and several locking slots 12 are also located inside the split disk 8 near the outer wall of the split disk 8. The shape characteristics of the locking block 9 and the locking slot 12 can facilitate the smooth connection between the locking block 9 and the locking slot 12 when the split disk 8 is reset, so that the split disk 8 can be reset smoothly, and the position of the split disk 8 is restricted so that the split disk 8 can rotate synchronously with the split shaft 7.

[0043] In the working state, the locking block 9 engages with the locking slot 12, and the split shaft 7 and the split disc 8 rotate synchronously. When the two split discs 8 separate from each other, the locking block 9 and the locking slot 12 separate from each other. At this time, the split disc 8 can rotate freely on the split shaft 7, so that the wire rolls on the two split discs 8 can be removed in a stationary state, avoiding the difficulty of disassembling the wire rolls when they continue to rotate synchronously with the split shaft 7. When disassembling the wire rolls, the two split discs 8 can be pushed apart by the external supporting structure, and the supporting structure can use friction to limit the rotation of the split discs 8, so that the split discs 8 are stationary. The split discs 8 will use several elastic bodies 11 to drive the rotating ring 10 to rotate relative to the split shaft 7. The several elastic bodies 11 on the rotating ring 10 can provide elastic force for the reset of the split discs 8.

[0044] It should be noted that when the card block 9 and the card slot 12 are not completely separated, the split shaft 7 and the split disk 8 will still rotate synchronously. At this time, the following can be used: Figure 5 The structure of the insert post 13 and slot 14 shown means that the two discs 8 are not completely separated. The insert posts 13 on the two discs 8 can provide support for the wire roll and prevent some of the wire from falling through the gap between the two discs 8. Of course, if the wire roll is removed from the two discs 8 after it has been bundled, then the insert post 13 and slot 14 are no longer required.

[0045] Furthermore, a protective cover 15 is provided on the split shaft 7 to isolate the rotating ring 10 and the elastic body 11. The protective cover 15 is slidably disposed on the split shaft 7 and is connected to the split plate 8.

[0046] When the positions of several reels 4 are changed, the empty reel 4 will move to the winding station. At this time, the steel wire is wound on the reel 4. The steel wire ends cut between the two reels 4 are prone to overlap or entangle with the swivel 10 and the elastic body 11 on the horizontal shaft 3. To avoid this phenomenon, the swivel 10 and the elastic body 11 can be shielded and protected by the cover 15. Since the divider 8 can move on the divider shaft 7, the cover 15 can be fixedly connected to the divider 8. The cover 15 is allowed to slide on the divider shaft 7.

[0047] Furthermore, several right-angle hooks 16 are provided on the side flanges of both sides of the line plate 4.

[0048] The central area of ​​the reel 4 is used to wind up the steel wire, and the side guards on both sides of the reel 4 are used to confine the steel wire within it. With the setting of several right-angle hooks 16, when the reel 4 at the winding station is changed, the previous reel 4 and the reel 4 at the winding station can use the right-angle hooks 16 to hook the steel wire and rotate synchronously. This allows the steel wire to be wound smoothly on the empty reel 4 and avoids the steel wire from being wound on the horizontal axis 3 outside the empty reel 4, which facilitates a smooth transition of the steel wire winding work.

[0049] It should be noted that the cut wire ends can also be fixed using the right-angle hook 16, thus preventing the wire ends from failing to rotate synchronously with the reel 4. This method also eliminates the need to fix the wire ends to the reel 4 using an external structure.

[0050] In some embodiments, at least one auxiliary wheel 25 may be provided between the two sides of the coil 4. The auxiliary wheel 25 is close to the side of the coil 4. The auxiliary wheel 25 is mounted on the adjusting plate 1 via a telescopic rod 26. The fixed end and the movable end of the telescopic rod 26 are connected by a spring piece 27. By using the auxiliary wheel 25 to press the wire end onto the coil 4, the wire winding operation can be smoothly carried out without the need for other external auxiliary structures to fix the wire end. The auxiliary wheel 25 can be set at any position in the circumferential direction of the coil 4, as long as it can perform the above functions. As the thickness of the wire winding on the coil 4 gradually increases, the wire can push the auxiliary wheel 25 to move in the opposite direction. The auxiliary wheel 25 pushes the telescopic rod 26 to retract, and the spring piece 27 undergoes elastic deformation.

[0051] Furthermore, the cutting unit 6 includes a movable ring 17 that can be slidably disposed on the column 2 and a knife groove 18 that is opened on the side wall of the column 2 along the length direction of the column 2. An inclined arm 19 and a knife 20 are respectively rotatably disposed on the movable ring 17 and in the knife groove 18. The inclined arm 19 and the knife 20 are rotatably connected to each other, and the knife 20 is used in conjunction with the knife groove 18.

[0052] When the reel 4 at the winding station is replaced, the wire section between the two reels 4 will move synchronously with the reel 4 and approach the column 2. At this time, the moving ring 17 is moved, such as... Figure 3As shown, in the triangle formed by the three connection points between the moving ring 17, the inclined arm 19, and the cutter 20, the upward movement of the moving ring 17 will shorten one of the vertical sides of the triangle. At this time, the inclined arm 19, as the hypotenuse of the triangle, will push the cutter 20 upward. That is, the moving ring 17 can push the horizontal cutter 20 upward and rotate through the inclined arm 19. The rotatable connection between the inclined arm 19 and the cutter 20 is the basis for the movement of the cutter 20. The cutter 20 cooperates with the cutter groove 18 to cut the steel wire segment, thereby separating the steel wires on the two wire reels 4.

[0053] Furthermore, a sliding post 21 is provided on the outer wall of the moving ring 17;

[0054] The switching structure also includes an outer ring 22 located outside several columns 2 and fixedly installed. The inner wall of the outer ring 22 is provided with an annular groove that works with the sliding column 21. The annular groove is composed of an arc groove 23 and a V groove 24.

[0055] The outer ring 22 is located outside the adjusting plate 1, and the sliding column 21 is fixed. When the adjusting plate 1 rotates, it will drive the sliding column 21 to slide in the ring groove through the column 2. When the sliding column 21 slides in the arc groove 23, the position of the moving ring 17 on the column 2 is fixed. When the sliding column 21 slides in the V groove 24, the moving ring 17 moves vertically on the column 2, thereby providing power for the cutting unit 6 to cut the steel wire.

[0056] A wire winding machine includes the switching structure described above, as well as a wire feeding structure for carrying and releasing the wire, a straightening structure for straightening the wire, a tension control structure for adjusting the winding tension of the wire, a wire laying structure for arranging the wire neatly, and a spreading structure for separating the two spools 8 on the wire spool 4.

[0057] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
