Abstract
Description
Technical Field
[0001] This invention relates to the field of metal resource recycling, and in particular to a winding machine and winding method for copper tie rods. Background Technology
[0002] Metal resource recycling aims to transform waste metal products into reusable metal materials, achieving resource recycling. During recycling, waste items such as electronic products and scrapped vehicles are first collected and sorted, then disassembled to separate different metal parts. Subsequently, non-metallic impurities are further removed through crushing and sorting. The smelting process employs upward-drawing copper processing technology, directly drawing high-purity molten metal into continuous copper rods. This process avoids the multiple casting and rolling processes of traditional smelting. Finally, the copper rods are evenly wound into standard copper discs using a winding machine, facilitating storage and transportation, and can be directly used as raw materials for subsequent processes such as wire drawing and extrusion, forming a complete closed-loop utilization system for copper resources.
[0003] In the upward-drawing copper processing flow of metal resource recycling, when the copper rod is wound into a copper disc, the operator presses the stop button to stop the winding equipment and ensure safety when a coil of copper is nearly completed. Next, the fully wound copper disc is removed from the equipment, a new empty drum is installed, and the equipment is restarted. The copper rod will then be driven by the equipment to be wound evenly and tightly onto the new drum, gradually forming a new copper disc.
[0004] The shortcomings of the existing technical solutions are that the machine must be stopped first during the roll changing process. The process of stopping the machine, unloading the full roll of copper discs and restarting the equipment takes a long time, which reduces the overall production efficiency. Summary of the Invention

At least two sets of rotating disks are rotatably mounted on the front side of the switching drum, and at least two sets of second motors are fixedly mounted inside the switching drum. The output end of each set of second motors is coaxially and fixedly connected to one set of rotating disks to drive the rotating disks to rotate. Each set of rotating disks is equipped with a cutting mechanism to cut the copper rod passing above the winding mechanism and fix the leading end of the copper rod. A winding mechanism is also mounted on the rotating disks, and the rotating disks can drive the winding mechanism to rotate, causing the copper rod to wind around the side of the winding mechanism to form a copper coil.
[0007] As a further aspect of the present invention: each group of the winding rod mechanism includes an electric telescopic rod fixedly mounted on a corresponding rotating disk, and a connecting seat is fixedly mounted on the telescopic end of the electric telescopic rod; multiple sets of hinge plates are movably hinged around the electric telescopic rod on the rotating disk, and a support rod is movably hinged to the front end of each set of hinge plates, and each set of support rods is movably hinged to the connecting seat; a winding plate is fixedly mounted on the side of the hinge plate, and the multiple sets of winding plates are arranged around the electric telescopic rod to form a support structure for winding copper rod.
[0008] As a further aspect of the present invention: a baffle is fixedly provided on one side of each set of support rods, the baffle extending radially along the rotating disk to prevent the copper rod from detaching from the winding plate.
[0009] As a further aspect of the present invention: the cutting mechanism includes an electric telescopic device fixedly mounted on a rotating disk, and an electric cutting head is fixedly mounted on the telescopic end of the electric telescopic device.
[0010] As a further aspect of the present invention: the electric cutting head is provided with cutting teeth at the biting end to cut the copper rod into a leading end and a tail end. The electric cutting head is also provided with clamping teeth to fix the leading end of the copper rod and drive the copper rod to wind around the winding mechanism.
[0011] As a further embodiment of the present invention: the electric telescopic device is fixedly installed inside the rotating disk, the front end of the rotating disk has a through-hole, the electric cutting head protrudes from the through-hole, and the electric telescopic device can drive the electric cutting head into the through-hole.
[0012] As a further aspect of the present invention: an inner conductive slip ring is provided between the output end of the second motor and the switching drum. One end of the inner conductive slip ring is electrically connected to the electric telescopic device, the electric cutting head and the electric telescopic rod, and the other end is electrically connected to an external power source.
[0013] As a further aspect of the present invention: the driving mechanism includes a first motor fixedly installed within a support frame, a drive wheel fixedly installed at the output end of the first motor, a transmission wheel fixedly installed coaxially on the rear side of the switching drum, and a transmission belt fitted onto the transmission wheel and the drive wheel.
[0014] As a further aspect of the present invention: the support frame is provided with an outer conductive slip ring in cooperation with the side of the switching drum. A portion of the outer conductive slip ring is electrically connected to the inner conductive slip ring, and the other portion is electrically connected to an external power source.
[0015] A winding method for a rod winding machine includes the following steps: S1. First, wind the copper rod around a set of winding mechanisms, and then rotate the winding mechanisms to form a copper disc; S2. The drive mechanism drives the switching drum to rotate, so that the copper rod can pass over another set of winding mechanisms and into the cutting opening of the cutting mechanism; S3. The cutting mechanism cuts the copper rod and fixes the leading end of the copper rod. The winding mechanism rotates, causing the copper rod to wind around the winding mechanism, thus realizing automatic winding. S4. When unwinding, the cutting mechanism loosens the leading end of the copper rod and retracts it into the through hole.
[0016] The beneficial effects of this invention are: 1. In this invention, the winding machine has two sets of rotating disks on the front side of the switching drum, each disk corresponding to a winding mechanism. The switching drum is driven to rotate by a drive mechanism. When a roll change is needed, the first motor starts, and through the drive wheel, transmission belt, and transmission wheel, the switching drum rotates, allowing the winding mechanism with the pre-formed copper disc to exchange positions with the idle winding mechanism. The cutting mechanism automatically cuts and fixes the coil, achieving uninterrupted production. When one winding mechanism completes the roll change, the other can immediately begin work, greatly reducing production downtime caused by roll changes, improving equipment utilization, and solving the problem of low efficiency in manual roll changes.
[0017] 2. In this invention, the retraction of the electric telescopic rod of the winding mechanism moves the connecting seat backward, causing the lower end of the support rod to move backward, thereby dragging the end of the hinge plate and moving the winding plate away from the center of the copper disc. Simultaneously, the baffle tilts outward. The electric telescopic device of the cutting mechanism can drive the electric cutting head into the through-hole, releasing the fixation on the leading end of the copper rod, making the unwinding operation extremely convenient. The winding plate's distance from the center of the copper disc and the baffle's tilt provide ample space for removing the copper disc. The cutting mechanism releases the leading end and retracts, allowing operators to quickly remove the copper disc, reducing the difficulty and time of manual operation. Attached Figure Description

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.
[0021] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention provides a winding machine for coiling copper tie rods, including a support frame 1, a switching drum 2 rotatably mounted on the support frame 1, and a drive mechanism 3 for driving the switching drum 2 to rotate, which is also provided on the support frame 1. Through the driving action of the drive mechanism 3, the switching drum 2 can be rotated flexibly.
[0022] Two sets of rotating disks 5 are rotatably mounted on the front side of the switching drum 2. Two sets of second motors 4 are fixedly mounted inside the switching drum 2, and the output end of each second motor 4 is coaxially and fixedly connected to one set of rotating disks 5. This allows the second motors 4 to drive the rotating disks 5 to rotate.
[0023] Each set of rotating disks 5 is equipped with a cutting mechanism 7. The cutting mechanism 7 includes an electric telescopic device 701 fixedly mounted on the rotating disk 5, and an electric cutting head 702 is fixedly mounted on the telescopic end of the electric telescopic device 701. The electric cutting head 702 has cutting teeth 7022 at its biting end, the main function of which is to cut the copper rod into a leading end and a tail end. The leading end is located on the copper rod output device side, and the tail end is located on the copper rod winding side. In addition, the electric cutting head 702 also has a clamping tooth 7021, the function of which is to fix the leading end of the copper rod. After clamping and fixing it, it can drive the copper rod to wind around the winding mechanism 6. The specific working process is as follows: when the second motor 4 drives the rotating disk 5 to rotate, the rotating disk 5 will simultaneously drive the winding mechanism 6 and the electric cutting head 702 to rotate. At this time, the electric cutting head 702 bites the end of the copper rod, and under the action of rotational force, the copper rod can be wound around the side of the rod winding mechanism 6 by the electric cutting head 702.
[0024] like Figure 5 As shown, the electric telescopic device 701 is fixedly installed inside the rotating disk 5. The front end of the rotating disk 5 has a through-hole 501, through which the electric cutting head 702 protrudes. The electric telescopic device 701 has the function of driving the electric cutting head 702 into the through-hole 501. When the electric cutting head 702 enters the through-hole 501, the leading end of the copper rod will disengage from the electric cutting head 702, making the disassembly of the copper disk more convenient and faster.
[0025] A winding mechanism 6 is also provided on the rotating disk 5. The rotating disk 5 can drive the winding mechanism 6 to rotate, and the copper rod is wound around the side of the winding mechanism 6 to gradually form a copper coil. Each winding mechanism 6 includes an electric telescopic rod 601 fixedly mounted on the corresponding rotating disk 5. The telescopic end of the electric telescopic rod 601 is fixedly provided with a connecting seat 602. Multiple sets of hinge plates 605 are movably hinged around the electric telescopic rod 601 on the rotating disk 5. Each set of hinge plates 605 has a support rod 603 movably hinged at its front end. Each set of support rods 603 is movably hinged to the connecting seat 602. A baffle 604 is fixedly provided on one side of each set of support rods 603. The baffle 604 extends radially along the rotating disk 5. Its main function is to prevent the copper rod from detaching from the winding plate 606 and to ensure that the copper rod can be stably wound on the winding mechanism 6. A winding plate 606 is fixedly installed on the side of the hinge plate 605. The winding plate 606 has a soft contact surface on its side. Multiple sets of winding plates 606 are arranged around the electric telescopic rod 601, forming a support structure for winding the copper rod. The specific working process is as follows: When the clamping teeth 7021 fix the end of the copper rod, the second motor 4 drives the rotating disk 5 to rotate. The rotating disk 5 further drives the multiple sets of winding plates 606 to rotate. Under the action of rotational force, the copper rod will be wound on the winding plate 606, gradually forming a copper disc. After winding is completed, the switching drum 2 will rotate, driving the copper disc to rotate, so that the winding mechanism 6 with the copper disc and the empty winding mechanism 6 are exchanged. The traction copper rod on the copper disc passes through one side of another set of rotating disks 5 and is located in the jaw of the corresponding electric cutting head 702. At this time, the electric cutting head 702 will bite off the copper disc, and the second motor 4 will continue to wind the remaining tail end. When the winding mechanism 6 needs to remove the copper disc, the electric telescopic rod 601 on the corresponding winding mechanism 6 can be activated. The electric telescopic rod 601 retracts, causing the connecting seat 602 to move backward. The connecting seat 602 causes the lower end of the support rod 603 to move backward, thereby dragging the end of the hinge plate 605, so that the winding plate 606 is away from the center of the copper disc. At the same time, the baffle 604 tilts outward, which provides convenient conditions for removing the copper disc. Meanwhile, another winding mechanism 6 will perform a winding operation at the same time, ensuring the continuity of production.
[0026] The drive mechanism 3 includes a first motor 301 fixedly mounted within the support frame 1. A drive wheel 302 is fixedly mounted at the output end of the first motor 301. A transmission wheel 303 is coaxially fixedly mounted on the rear side of the switching drum 2. A transmission belt 304 is fitted onto the transmission wheel 303 and the drive wheel 302. When it is necessary to switch the winding mechanism 6, simply start the first motor 301. The first motor 301 drives the drive wheel 302 to rotate, which in turn drives the transmission wheel 303 to rotate via the transmission belt 304. The transmission wheel 303 then drives the switching drum 2 to rotate, thereby rotating the other winding mechanism 6 to a suitable angle so that the traction copper rod can pass through the bite of the electric cutter head 702 on another set of rotating discs 5, preparing for subsequent roll changing operations.
[0027] An outer conductive slip ring is fitted to the side of the support frame 1 and the switching drum 2. An inner conductive slip ring 8 is fitted between the output end of the second motor 4 and the switching drum 2. One part of the outer conductive slip ring is electrically connected to the inner conductive slip ring 8, and the other part is electrically connected to an external power source. One end of the inner conductive slip ring 8 is electrically connected to the electric telescopic device 701, the electric cutting head 702, and the electric telescopic rod 601, and the other end is electrically connected to the outer conductive slip ring. This achieves continuous power supply, ensuring stable operation of each electric component during rotation. A wireless control system can be installed inside the rotating disk 5. This system can adjust the state of the electric telescopic device 701, the electric cutting head 702, and the electric telescopic rod 601 in a timely manner, allowing the entire device to be flexibly adjusted according to different production needs, thereby improving production efficiency and product quality.
[0028] Working Principle: The operator first manually fixes one end of the copper rod to a set of electric cutting heads 702, where the clamping teeth 7021 on the electric cutting heads 702 grip the end of the copper rod. Then, the corresponding first motor 301 is started, driving the drive wheel 302 to rotate. The drive wheel 302, through the transmission belt 304, drives the transmission wheel 303 to rotate, which in turn drives the switching drum 2 to rotate, causing the winding mechanism 6, with the copper rod wound around it, to enter the working position. At this time, the corresponding second motor 4 starts, driving the connected rotating disk 5 to begin rotating. Simultaneously, the rotating disk 5 drives the electric cutting heads 702 of the winding mechanism 6 and the cutting mechanism 7 to rotate synchronously. Under the action of rotational force, the copper rod is continuously pulled and gradually wound onto the take-up plate 606. As the rotating disk 5 continues to rotate, the copper rod gradually forms a copper disc on the take-up plate 606.
[0029] When the copper disc being wound reaches the preset length, a roll change operation is required. At this time, the first motor 301 starts again, driving the switching drum 2 to rotate via the drive mechanism 3, causing the winding mechanism 6 with the formed copper disc to exchange positions with the empty winding mechanism 6. During the switching process, the traction copper rod on the copper disc passes one side of another set of rotating disks 5 and is positioned precisely within the jaws of the electric cutting head 702 on that set of rotating disks 5. Then, the electric cutting head 702 starts, and its cutting teeth 7022 quickly cuts the copper rod, forming a new leading end and tail end. At the same time, the clamping teeth 7021 fix the new leading end, and then the second motor 4 corresponding to the winding mechanism 6 starts, driving the rotating disk 5 to rotate, thereby causing the new winding mechanism 6 to start working, driving the copper rod to wind around its winding plate 606, realizing automatic roll change, while the second motor 4, which had previously finished winding, continues to wind the remaining tail end, ensuring that the winding process is uninterrupted.
[0030] After the winding mechanism 6 completes the winding of the copper rod to form a complete copper disc, a dewinding operation is required to remove the copper disc. At this time, the electric telescopic rod 601 on the winding mechanism 6 retracts, causing the connecting seat 602 to move backward. The movement of the connecting seat 602 causes the lower end of the support rod 603, which is movably hinged to it, to move backward, thereby dragging the end of the hinge plate 605 and moving the winding plate 606 away from the center of the copper disc. At the same time, the baffle 604 fixed to one side of the support rod 603 tilts outward, providing sufficient space for the removal of the copper disc. Simultaneously, the electric telescopic device 701 of the cutting mechanism 7 is activated, releasing the fixation on the leading end of the copper rod, allowing the leading end of the copper rod to detach from the electric cutting head 702, and driving the electric cutting head 702 into the through-hole 501 at the front end of the rotating disk 5. At this time, the operator can easily remove the formed copper disc from the winding mechanism 6. While unwinding, another winding mechanism 6 continues to rewind under the drive of the second motor 4, ensuring the continuity of the entire production process.
[0031] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
