Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery and equipment, and in particular to a copper alloy wire packaging mechanism. Background Art

[0002] Copper alloy wire is widely used in electrical cables, requiring smooth wire pulling from drums. To increase automation and reduce time spent on repackaging and wire splicing, copper alloy wire is typically packaged in large drums weighing hundreds of kilograms. This process is commonly used to package copper alloy wire in large drums. This process ensures that hundreds of kilograms of copper alloy wire can be loaded into drums through wire packaging machinery. The process requires the wire to be neatly stacked, coiled on top of each other, to prevent tangling during wire pulling, which could disrupt cable manufacturing operations.

[0003] At present, the wire packaging machinery and equipment are mainly conventional wire take-up machines or wire droppers. The structure is to wind the copper alloy wire on a 90° arc-shaped reel, and then the coiled copper alloy wire is gradually dropped into the packaging barrel one by one. In this process, it is easy for the coiled copper alloy wire to suddenly fall into the packaging barrel in multiple coils. In addition, the arc-shaped reel is relatively long, and the outlet end is far from the bottom of the packaging barrel. The multiple coils of copper alloy wire fall into the packaging barrel, and the drop height varies with the amount of copper alloy wire accumulated. Therefore, the fallen copper alloy wires are prone to cause disorderly overlap and entanglement with each other. It is particularly easy for the center of the packaging barrel to be high and the edges of the packaging barrel to be low. The coil diameters are uneven, and a vibration motor needs to be added to make it slightly flat. However, this makes it easier for the copper alloy wires in the barrel to overlap and entangle with each other, resulting in more likely to knot and entangle when the wires are pulled out of the barrel, affecting the continuous operation of cable manufacturing.

DETAILED DESCRIPTION

[0026] The following is combined with Figure 1-8 The embodiments of the present invention are described in detail.

[0027] A copper alloy wire packaging mechanism includes an eccentric rotary table mechanism 2, a lifting device 1, a wire feeding mechanism 3, a coil guide wheel mechanism 4, and a load-bearing platform 5. The eccentric rotary table mechanism 2 is arranged on the lifting fixed platform 19 of the lifting device 1, the coil guide wheel mechanism 4 is arranged on the eccentric rotary table mechanism 2, and the load-bearing platform 5 is located below the coil guide wheel mechanism 4. The copper alloy wire 13 transported by the wire feeding mechanism 3 passes through the eccentric rotary table mechanism 2 and is wound around the coil guide wheel mechanism 4.

[0028] The copper alloy wire 13 conveyed by the wire feeding mechanism 3 passes through the coiling guide wheel mechanism 4. Under the action of the eccentric rotating platform mechanism 2, the copper alloy wire 13 is doffed into a coil of a certain diameter onto the load-bearing platform 5. When the wire is wound up on the load-bearing platform 5, the coiling guide wheel mechanism 4 rotates a certain angle, causing the second coil of the copper alloy wire 13 to fall onto the first coil at a certain angle. This process continues in this way, ultimately causing the copper alloy wire 13 to be stacked and wound in an orderly manner in a plum blossom shape on the load-bearing platform 5, forming a hollow copper alloy wire stacked cylinder. After winding is completed, the packaging barrel is inserted from the top into this hollow copper alloy wire stacked cylinder. The packaging barrel is then flipped 180° by a flipping mechanism or manually, resulting in the packaged copper alloy wire barrel.

[0029] As the wire-taking height gradually increases, the lifting device drives the eccentric rotary table mechanism 2 to rise, so that the lowest guide wheel group in the coil guide wheel mechanism 4 always maintains a certain distance from the upper surface of the accumulated copper alloy wire, achieving a stable plum blossom wire-taking effect.

[0030] Preferably, the eccentric rotary table mechanism 2 includes an eccentric drive device 9, an active eccentric wheel 8, and a rotating platform 20. The eccentric drive device 9 is provided on the lifting fixed platform 19. The eccentric drive device 9 is a motor. The output shaft of the motor is connected to one end of the active eccentric wheel 8 by a keyway. The other end of the active eccentric wheel 8 is provided with a bearing 7, and the bearing 7 is connected to the rotating platform 20. The eccentric drive device 9 drives the active eccentric wheel 8 to rotate, and the active eccentric wheel 8 then drives the rotating platform 20 to rotate, so that the copper alloy wire 13 dropped from the coil guide wheel mechanism 4 is wound up on the load-bearing platform 5.

[0031] Preferably, the eccentric rotating platform mechanism 2 further includes two passive eccentric wheels 6, which are located on the left and right sides of the active eccentric wheel 8. Two bearings 25 are provided at each end of the passive eccentric wheel 6. The second bearing 25 at the lower end of the passive eccentric wheel 6 is connected to the lifting and fixing platform 19, and the second bearing 25 at the upper end of the passive eccentric wheel 6 is connected to the rotating platform 20. The passive eccentric wheels 6 are provided to assist the rotation of the rotating platform 20 and maintain the stability of the entire rotating platform 20.

[0032] The eccentric center distance between the active eccentric wheel 8 and the passive eccentric wheel 6 is d1. The eccentric rotating platform mechanism 2 drives the coil guide wheel mechanism 4, moving along a trajectory with a radius of d1. The copper alloy wire 13 is doffed onto the load-bearing platform 5, forming a coil with a diameter of d3. The inner diameter of the outer wall of the packaging barrel is d4. The difference between the inner diameter d4 of the packaging barrel and the coil diameter d3 is d2. d1 = d2 = d4 - d3, ensuring that the stacked coiled copper alloy wires 13 are arranged in a quincunx pattern within the packaging barrel, without overlapping or excessively staggered.

[0033] Preferably, the lifting device 1 includes a lifting drive device 23, a lifting screw 22, a screw nut 21, and a lifting fixed platform 19. The lifting drive device 23 drives and connects the lifting screw 22, the screw nut 21 is arranged on the lifting screw 22, and the lifting fixed platform 19 is installed on the screw nut 21. The lifting drive device 23 is a motor, and the lifting drive device 23 drives the lifting screw 22 to rotate, thereby driving the lifting fixed platform 19 on the screw nut 21 to rise and fall. When the copper alloy wire 13 is wound on the load-bearing platform 5 for one circle, the lifting fixed platform 19 rises to a corresponding height, so that the wire-out position of the copper alloy wire 13 in the coil guide wheel mechanism 4 and the upper surface of the copper alloy wire pile below are always kept within a certain distance, achieving the effect of stable plum blossom winding.

[0034] Preferably, the wire feeding mechanism 3 includes a wire feeding drive device and a wire feeding assembly. The wire feeding drive device is a motor. The wire feeding assembly includes a driving gear 15, a passive gear 16, two wire feeding wheels 14, and two rotating shafts 26. A driving gear 15 and a wire feeding wheel 14 are installed on one rotating shaft 26, and a passive gear 16 and a wire feeding wheel 14 are installed on the other rotating shaft 26. The driving gear 15 and the passive gear 16 are meshed with each other. The wire feeding drive device is driven and connected to the rotating shaft 26 on which the driving gear 15 is installed. The two wire feeding wheels 14 clamp the copper alloy wire 13 to each other. The wire feeding drive device drives the rotating shaft 26 on which the driving gear 15 is installed to rotate. The driving gear 15 then drives the meshed passive gear 16 to rotate, thereby driving the other rotating shaft 26 to rotate synchronously. The wire feeding wheels 14 on the two rotating shafts 26 rotate together to provide wire feeding power for the copper alloy wire 13. The coiling speed of the copper alloy wire is the same as the wire feeding speed, thereby avoiding pulling or loosening of the copper alloy wire 13.

[0035] Preferably, the loop forming guide wheel mechanism 4 includes a loop forming drive device and a loop forming guide wheel rotating device. The loop forming guide wheel rotating device is installed on the rotating platform 20, and the loop forming drive device drives the loop forming guide wheel rotating device to rotate.

[0036] When one circle of wire is wound on the load-bearing platform 5, the circle-forming drive device drives the circle-forming guide wheel mechanism to rotate a certain angle, so that the second circle is offset by a certain angle and falls on the first circle. Similarly, the circle-forming drive device can be controlled by the PLC to achieve the same rotation angle of the circle guide wheel mechanism each time.

[0037] Preferably, the coil guide wheel rotating device includes a coil rotating shaft 17, a coil pulley 18, a coil guide wheel mounting plate 12, a guide wheel mounting rod 10 and a guide wheel group 11. The coil rotating shaft 17 is rotatably arranged on the rotating platform 20. The coil pulley 18 is mounted on the outer periphery of the coil rotating shaft 17. The coil driving device is drive-connected to the coil pulley 18. The coil wheel mounting plate 12 is arranged at the bottom end of the coil rotating shaft 17. A plurality of guide wheel mounting rods 10 are mounted below the coil wheel mounting plate 12. A guide wheel group 11 is arranged at the lower part of the guide wheel mounting rod 10. In this embodiment, the number of guide wheel mounting rods 10 and guide wheel group 11 is set to 8.

[0038] The length of the guide wheel mounting rod 10 increases in the direction of the copper alloy wire 13's travel, allowing the installation height of the guide wheel assembly 11 to be gradually lowered to meet the coiling requirements, allowing the copper alloy wire 13 to be more effectively coiled. The guide wheel assembly 11 is determined by its installation height, and its inclination angle increases in the direction of the copper alloy wire 13's travel.

[0039] The coiling rotating shaft 17 is hollow, and the copper alloy wire 13 transported by the wire feeding mechanism 3 passes through the coiling rotating shaft 17 , then passes around each guide wheel group 11 in sequence, and is output from the last guide wheel group 11 .

[0040] Preferably, a fixing hole 24 is provided on the coil guide wheel mounting plate 12, and the upper end of the guide wheel mounting rod 10 is inserted into the fixing hole 24 for installation. The coil guide wheel mounting plate 12 is provided with a plurality of fixing holes 24 with different coil diameters, and the guide wheel mounting rod 10 is inserted into the fixing holes 24 with different coil diameters, thereby adjusting the position of the guide wheel assembly 11, and then adjusting the coiling position of the copper alloy wire 13, to ensure that the copper alloy wire 13 falls into the packaging barrel.

[0041] Preferably, the last guide wheel assembly 11 in the direction of travel of the copper alloy wire 13 is in a vertical position. The guide wheel assemblies 11 are gradually tilted from the horizontal position of the first guide wheel assembly 11 to the vertical position of the last guide wheel assembly 11. After the copper alloy wire 13 passes around the last guide wheel assembly 11, it descends vertically, so that the copper alloy wire 13 can form a loop.

[0042] The load-bearing platform 5 is movable horizontally. The copper alloy wire 13, which has passed through the coiling guide wheel mechanism 4, is deposited on the load-bearing platform 5 in a plum blossom shape, forming a hollow cylindrical copper alloy wire stack. Once the hollow cylindrical copper alloy wire stack formed by the copper alloy wire 13 on the load-bearing platform 5 reaches a specified weight, the load-bearing platform 5 is pulled out of its original position. The packaging barrel is then inserted into the hollow cylindrical copper alloy wire stack from above and flipped 180 degrees, with the barrel opening facing upward. This completes the packaged copper alloy wire barrel.
