Description
Technical Field
[0001] This utility model belongs to the field of winding machines, specifically relating to an automatic zinc wire winding machine. Background Technology
[0002] Zinc wire, as a soft and chemically reactive industrial material, faces numerous challenges in its winding process. Due to its low hardness, the sharp edges and burrs of metal reels easily scratch the surface of the zinc wire when using metal reels; therefore, plastic reels are typically used for zinc wire winding. However, existing automatic zinc wire winding machines have deficiencies in their reel fixing methods.
[0003] Traditional winding machines typically rely solely on inserting the winding spool into the spool mounting hole and having a limiting disc on the spool clamp the spool, using friction to drive the spool's rotation. This method makes it difficult to ensure the spool's stability. During the zinc wire winding process, as the number of winding layers increases and tension changes, relative slippage can easily occur between the spool and the winding spool, resulting in loose and unevenly arranged zinc wire.
[0004] Alternatively, after inserting the winding shaft into the spool, the spool can be fixed to the winding shaft with bolts. However, this takes a long time to install and remove the spool, which affects the efficiency of zinc wire winding. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides an automatic zinc wire winding machine that enables rapid assembly and disassembly of the wire spool on the winding machine, improving work efficiency and ensuring synchronous rotation of the wire spool and winding shaft, thereby improving the winding quality of the zinc wire.
[0006] The specific technical solution adopted in this utility model is as follows:
[0007] An automatic zinc wire winding machine includes a frame and a wire feeding assembly. The frame has a pair of winding shafts and translation shafts. The wire spool has mounting holes. The winding shafts are coaxial with the mounting holes. The winding shafts are connected to the power output shaft of a first motor and have the freedom to rotate on the frame. The translation shafts have the freedom to translate towards the winding shafts via a drive unit. Crucially, the winding shafts have a first limiting plate, and the translation shafts have a second limiting plate. The first limiting plate has a pin, which is parallel to the winding shaft. The wire spool has a insertion hole matching the pin.
[0008] The translation axis is rotatably fitted inside the sleeve, which is connected to the drive unit via a connecting plate. A guide tube is provided on the frame, and the sleeve and the guide tube are fitted together to form a sliding guide fit.
[0009] The frame is provided with a slide rail located below the spool, the output end of the slide rail is connected to the storage box, and a flexible pad is provided on the sliding surface of the slide rail.
[0010] The frame is equipped with an angle adjustment assembly for the slide rail. The receiving end of the slide rail is hinged to the frame via a first hinge shaft. The angle adjustment assembly includes a telescopic cylinder and a push plate. The push plate is hinged to the frame via a second hinge shaft. The telescopic cylinder acts on the working end of the push plate, which is located on one side of the second hinge shaft. The push plate has an elongated hole. The output end of the slide rail is fixedly connected to a round shaft. The frame is equipped with a sliding groove that mates with the round shaft. The two ends of the round shaft are respectively in sliding fit with the elongated hole and the sliding groove. The push plate swings around the second hinge shaft and drives the slide rail to swing around the first hinge shaft, driven by the telescopic cylinder.
[0011] The connecting plate is equipped with a pull rope, and the cantilever end of the pull rope is equipped with a hook.
[0012] The cable assembly includes a straightener, which is connected to a screw via a threaded sleeve. The screw is mounted on a frame and its axial direction is parallel to the winding shaft. A second motor drives the screw to rotate, giving the straightener the freedom to reciprocate along the screw's axial direction.
[0013] The pin is located on the first limiting plate, and the insertion length of the pin on the coil is less than the insertion length of the winding shaft.
[0014] The beneficial effects of this utility model are:
[0015] This invention employs a winding shaft and a pin to constrain the wire reel, ensuring that the reel rotates synchronously with the winding shaft and preventing slippage between them. This ensures that the zinc wire is tightly wound and neatly arranged on the reel, effectively improving the winding effect. It also reduces the pressure exerted on the reel by the first and second limiting discs, preventing reel deformation. Furthermore, the reel is easy to load and unload, contributing to improved efficiency in zinc wire winding operations.
[0016] A slide rail was added to the frame. After the winding operation on the reel is completed, the reel is pushed to separate it from the winding shaft. The reel slides down the slide rail into the storage box, eliminating the need for manual removal of the reel and reducing manual labor and human intervention.
[0017] The frame is also equipped with an angle adjustment component for the slide, which can flexibly adjust the tilt angle of the slide according to the actual weight and size of the spool, so that the spool can fall smoothly on the slide and slide off the slide.
[0018] When the pin is set on the first limit plate, the length of the pin inserted into the spool is less than the length of the winding shaft inserted into the spool. When installing the spool, the spool can be first fitted onto the winding shaft, which provides support for the spool. Then, the spool can be pushed and rotated on the winding shaft to align the insertion hole on the spool with the pin and form an insertion fit, which helps to improve the convenience of operation.

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0024] Specific implementation examples Figure 1 As shown, this utility model relates to an automatic zinc wire winding machine, including a frame 1 and a wire feeding assembly. A winding shaft 2 and a translation shaft 3 are arranged in pairs on the frame 1. A mounting hole 5 is provided on the wire reel 4. The winding shaft 2 is coaxially arranged with the mounting hole 5. The winding shaft 2 is connected to the power output shaft of a first motor and has the freedom to rotate on the frame 1. The translation shaft 3 has the freedom to translate towards the winding shaft 2 via a drive unit 6. Crucially, a first limiting disc 7 is provided on the winding shaft 2, and a second limiting disc 8 is provided on the translation shaft 3. A pin 9 is provided on the first limiting disc 7, and the pin 9 is arranged parallel to the winding shaft 2. A insertion hole 10 matching the pin 9 is provided on the wire reel 4. Figure 2 As shown, an annular groove is provided on the outer side of the mounting hole 5 on the coil 4. The annular groove is coaxial with the mounting hole 5, and the insertion hole 10 is provided in the annular groove.
[0025] The pin 9 and the winding shaft 2 work together to form a mechanical lock on the wire reel 4, so that the wire reel 4 can rotate synchronously with the winding shaft 2, ensuring that the zinc wire is tightly wound and neatly arranged, effectively improving the winding effect of the zinc wire on the wire reel 4, and also reducing the pressure of the first limiting plate 7 and the second limiting plate 8 on the wire reel 4, preventing the wire reel 4 from deforming.
[0026] During installation, the mounting hole 5 of the coil 4 is fitted onto the winding shaft 2. The coil 4 is rotated to align the insertion hole 10 with the pin 9. Pushing the coil 4 towards the pin 9 allows the pin 9 to be inserted into the insertion hole 10. In this embodiment, the winding shaft 2 and the frame 1 are relatively fixed in position. The translation shaft 3 has the freedom to move towards the winding shaft 2 with the help of the drive unit 6, thereby realizing the relative movement of the winding shaft 2 and the translation shaft 3. The translation shaft 3 moves towards the winding shaft 2 with the help of the drive unit 6, so that the first limiting plate 7 and the second limiting plate 8 are in contact with the coil 4, restricting the axial movement of the coil 4 along the winding shaft 3. Combined with the locking effect of the pin 9 and the winding shaft 2 on the coil, the installation of the coil 4 is ensured to be secure.
[0027] Then the first motor and the wire laying assembly start up. The first motor drives the winding shaft 2 to rotate, and the wire laying assembly moves to make the zinc wire neatly wound on the wire spool 4.
[0028] After the zinc wire on the reel 4 is wound, the drive unit 6 drives the translation shaft 3 to move backward, which can remove the reel 4, simplifying the loading and unloading process of the reel 4 and helping to improve work efficiency.
[0029] The translation shaft 3 is rotatably fitted inside the sleeve 11. The sleeve 11 is connected to the drive unit 6 via a connecting plate 12. A guide tube 13 is provided on the frame 1. The sleeve 11 and the guide tube 13 are fitted together to form a sliding guide engagement. Specifically, a protrusion is provided on the side wall of the sleeve 11, and a guide groove matching the protrusion is provided on the guide tube 13. The guide groove is arranged along the axial direction of the guide tube 13. The sleeve 11 is limited by the engagement of the protrusion and the guide groove, ensuring that the sleeve 11 can move along the guiding direction of the guide tube 13, ensuring the movement accuracy and stability of the translation shaft 3, and thus improving the reliability of the coil 4. The drive unit 6 is a cylinder. The sleeve 11 is connected to the telescopic end of the cylinder via the connecting plate 12. The axial direction of the cylinder is parallel to the translation shaft 3.
[0030] A slide rail 14 is provided on the frame 1 below the wire spool 4. The output end of the slide rail 14 is connected to the storage box. A flexible pad is provided on the sliding surface of the slide rail 14. After the winding operation on the wire spool 4 is completed, the drive unit 6 drives the translation shaft 3 to move backward, pushing the wire spool 4 to separate it from the winding shaft 2. The wire spool 4 slides down the slide rail 14 into the storage box without the need for manual removal of the wire spool 4, reducing the degree of manual intervention. The flexible pad provides flexible cushioning for the wire spool 4, effectively preventing damage to the wire spool 4 due to collision during the fall, protecting the wire spool 4 and the wound zinc wire. The flexible pad is preferably made of polyurethane or rubber.
[0031] Furthermore, such as Figure 1 , Figure 3 As shown, the frame 1 is equipped with an angle adjustment assembly for the slide rail 14. The receiving end 15 of the slide rail 14 is hinged to the frame 1 via a first hinge shaft 16. The angle adjustment assembly includes a telescopic cylinder 17 and a push plate 18. The push plate 18 is hinged to the frame 1 via a second hinge shaft 19. The telescopic cylinder 17 acts on the working end of the push plate 18. The working end is located on the same side of the second hinge shaft 19 as the cable assembly. The push plate 18 is provided with an elongated hole 20. The output end of the slide rail 14 is fixedly connected to a round shaft 21. The frame 1 is provided with a sliding groove 22 that mates with the round shaft 21. The two ends of the round shaft 21 form a sliding fit with the elongated hole 20 and the sliding groove 22, respectively. The push plate 18 swings around the second hinge shaft 19 and drives the slide rail 14 to swing around the first hinge shaft 16 by the drive of the telescopic cylinder 17. The tilt angle of the slide rail 14 can be flexibly adjusted according to the actual weight and size of the spool 4, so that the spool 4 can slide smoothly off the slide rail 14.
[0032] The output end of the slide 14 is equipped with a counterweight, and in the free state, the output end of the slide 14 tends to flip downward. The telescopic end of the telescopic cylinder 17 extends and presses down on the action end of the push plate 18. The push plate 18 rotates around the second hinge axis 19, and the end of the push plate 18 with the elongated hole 20 tilts upward and acts on the round shaft 21. The round shaft 21 drives the slide 14 to rotate around the first hinge axis 16 as the push plate 18 rotates, thereby realizing the adjustment of the tilt angle of the slide 14.
[0033] Furthermore, the first hinge shaft 16 is located on the incoming wire side of the winding shaft 2. The extension of the telescopic end of the telescopic cylinder 17 can cause the output end of the slide rail 14 to tilt upward, raising the part of the slide rail 14 that receives the coil 4. This controls the drop distance of the coil 4 from the winding shaft 2 onto the slide rail 14, preventing the coil 4 from falling too far and causing a strong impact with the slide rail 14, thus further ensuring the smooth sliding of the coil 4.
[0034] Preferably, a pull rope 23 is provided on the connecting plate 12, and a hook 24 is provided at the cantilever end of the pull rope 23. In the free state, the hook 24 hangs naturally around the connecting plate 12. When the worker picks up the hook 24 and places it on the side of the coil 4 near the winding shaft 2 from above, as the connecting plate 12 and the translation shaft 3 move backward, the pull rope 23 becomes taut and the hook 24 fits against one side of the coil 4. As the connecting plate 12 and the translation shaft 3 continue to move backward, the hook 24 pulls the coil 4 towards the direction of the translation shaft 3, and the coil 4 automatically detaches from the winding shaft 2. There is no need for manual disassembly of the coil 4, saving labor. Furthermore, as the coil 4 automatically detaches from the winding shaft 2 under the pulling action of the hook 24 and slides down with the help of the slide rail 14, the worker can pick up the next coil 4 and wait for installation, shortening the waiting time and helping to further improve the efficiency of zinc wire winding.
[0035] The wire laying assembly includes a straightener 25, which is connected to a screw via a threaded sleeve 26. The screw 27 is mounted on the frame 1, and its axial direction is parallel to the winding shaft 2. A second motor drives the screw 27 to rotate, giving the straightener 25 the freedom to reciprocate along the axial direction of the screw 27. This straightens the zinc wire, ensuring that the zinc wire entering the winding process remains straight, and also achieves uniform laying of the zinc wire, so that the zinc wire is tightly and neatly wound on the reel 4.
[0036] When the pin 9 is set on the first limiting plate 7, the insertion length of the pin 9 on the coil 4 is less than the insertion length of the winding shaft 2. When installing the coil 4, the coil 4 can be installed by first fitting it with the winding shaft 2. The coil 4 is fitted on the winding shaft 2, and the winding shaft 2 provides support for the coil 4. Then, the coil 4 is pushed and rotated on the winding shaft 2 so that the insertion hole 10 on the coil 4 is aligned with the pin 9 and a insertion fit is formed, which helps to improve the convenience of operation.
