Description

Technical Field

[0001] This utility model relates to the field of aluminum coil processing technology, and in particular to a device for recycling the head and tail ends of aluminum coils with surface defects. Background Technology

[0002] In the field of aluminum coil processing technology, especially for the recycling of the beginning and end of aluminum coils with surface defects, existing processing methods face many challenges. A common practice is to directly collect these end coil fragments and then manually transport them to a designated processing area. However, with the rapid development of the aluminum coil processing industry, this traditional processing method has gradually revealed many shortcomings.

[0003] The utility model patent with authorization announcement number "CN217968520U", namely the horizontal extrusion flattening machine for aluminum coil head and tail remnants, includes a base on which a movable end component, a fixed end component, and a movable drive component are installed. This device improves the processing flow of head and tail remnants to a certain extent. Through horizontal extrusion, the device compresses the head and tail remnants of aluminum coils from a circular shape to a flat shape, thereby reducing the volume of the remnants and facilitating subsequent transportation and storage. However, this device still has significant drawbacks in practical applications. Specifically, the device relies entirely on manual handling during loading and unloading, which is not only time-consuming and labor-intensive, greatly reducing work efficiency, but also increases the safety risks for operators. During manual handling, operators need to frequently handle and move heavy aluminum coil head and tail remnants, easily leading to physical fatigue and muscle injury. Furthermore, improper operation or equipment malfunction may cause accidents, posing a serious threat to the life safety of operators. Therefore, a device for recycling the head and tail remnants of aluminum coils with surface defects is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that rely entirely on manual handling during the loading and unloading process. This is not only time-consuming and labor-intensive, greatly reducing work efficiency, but also increasing the safety risks for operators. During manual handling, operators need to frequently touch and move the heavy ends of aluminum coils, which can easily lead to physical fatigue and muscle injury. In addition, improper operation or equipment malfunction may also cause accidents, posing a serious threat to the life safety of operators. Therefore, this invention proposes a device for recycling the ends of aluminum coils with surface defects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for recycling the head and tail ends of surface-defect aluminum coils includes a base. An L-shaped pusher plate and a feeding plate are slidably connected to the top of the base via a slide rail and a slide block, respectively. A hydraulic cylinder is fixedly mounted on one side of the base, with one end of the piston rod of the hydraulic cylinder fixedly connected to one side of the L-shaped pusher plate. Mounting frames are fixedly connected to both sides of the base. A second hydraulic cylinder is fixedly mounted on the top inner wall of the mounting frame, with an upper pressure plate fixedly connected to the bottom of the piston rod of the second hydraulic cylinder. Slide grooves are formed on the inner walls of both sides of the mounting frame, and a common baffle mechanism for positioning and discharging is slidably connected within the two slide grooves. Two sets of transmission mechanisms for driving the feeding plate are provided on both sides of the base.

[0007] In one possible design, the transmission mechanism includes two rotating shafts, both of which are rotatably connected to one side of the base. Gears and pulleys are respectively fixedly connected to the outer circumference of the rotating shafts. The outer circumference of the two pulleys is driven by the same transmission belt. Two gears that are close to each other in the two sets of transmission mechanisms mesh with each other.

[0008] In one possible design, racks are fixedly connected to both sides of the L-shaped pusher plate and the feed plate, and the racks mesh with corresponding gears.

[0009] In one possible design, two T-shaped limiting grooves are provided on both sides of the feeding plate, and T-shaped limiting blocks are slidably connected in the T-shaped limiting grooves. The same support block is fixedly connected to one side of the two T-shaped limiting blocks on the same side. The two support blocks are provided with engaging grooves on the sides away from each other. A connecting plate is fixedly connected to the bottom of the support block. Mounting blocks are fixedly connected to both sides of the base. A limiting rod is fixedly connected to the side of the mounting block near the support block. One end of the limiting rod slides through one side of the corresponding connecting plate. The same tension spring is fixedly connected to the side of the mounting block and the corresponding connecting plate near each other. The tension spring is sleeved on the outer circumference of the limiting rod.

[0010] In one possible design, the material blocking mechanism includes two sliders slidably connected in corresponding grooves. The two sliders are fixedly connected to the same baffle on their adjacent sides. The bottom of the slider contacts the top of the support block. The length of the slider is greater than the length of the baffle. The slider is adapted to the engaging groove. The top of the base has an installation groove, and a reset mechanism for disengaging the slider from the engaging groove is provided in the installation groove.

[0011] In one possible design, the reset mechanism includes a first abutment, two second abutments, and two connecting rods. The top of the first abutment has an inclined surface, and the first abutment is slidably connected in the mounting groove. The two second abutments are slidably connected in corresponding grooves. The two connecting rods are rotatably connected to the inner walls of both sides of the mounting frame. Two symmetrical and through connecting holes are opened on one side of each connecting rod. Extension shafts are fixedly connected to both sides of the first abutment and the sides of the two second abutments that are close to each other. The extension shafts pass through the corresponding connecting holes, and a limiting plate for preventing them from detaching from the connecting rods is fixedly connected to one end of each extension shaft that passes through the connecting hole.

[0012] Working Principle: In this application, when it is necessary to recycle the head and tail ends of aluminum coils with surface defects, simply place them in the area between the L-shaped pusher plate and the mounting frame at the top of the base. Then, activate hydraulic cylinder one. The piston rod of hydraulic cylinder one will push the L-shaped pusher plate, thereby moving the head and tail ends of the aluminum coils with surface defects towards the mounting frame. At this time, the L-shaped pusher plate utilizes the cooperation of racks on both sides and two sets of transmission mechanisms, and through the racks on both sides of the feeding plate, it drives the feeding plate to move towards the L-shaped pusher plate. Because the sliding plane of the L-shaped pusher plate is higher than the top of the feeding plate, the L-shaped pusher plate will eventually push the head and tail of the aluminum coil with surface defects to the top of the feeding plate. Then, hydraulic cylinder two is activated, and the piston rod of hydraulic cylinder two drives the upper pressure plate to move downward, flattening the head and tail of the aluminum coil with surface defects into a flattened aluminum coil. As the feeding plate moves towards the L-shaped pusher plate, the bottom of the feeding plate will contact the inclined surface of the top of the abutment block one and push the abutment block one downward in the mounting groove. Then, the abutment block one... The extension shafts on both sides drive the connecting rod to rotate, which in turn drives the second abutment block to move upward in the groove on the inner wall of the mounting frame via the extension shaft on one side. This pushes the entire baffle mechanism upward, causing the sliders on both sides of the baffle mechanism to disengage from the locking groove. Then, the support block moves towards the L-shaped pusher plate under the pull of the tension spring. Then, hydraulic cylinder two retracts its piston rod, and hydraulic cylinder one also retracts its piston rod, driving the L-shaped pusher plate to reset. At the same time, due to the transmission of the two sets of transmission mechanisms, the feeding plate also moves outward with the support blocks on both sides, and drives the flattened aluminum coil to move outward together from the gap at the bottom of the baffle mechanism. When the feeding plate moves to the appropriate position, the sliders on both sides of the baffle mechanism will engage downward into the locking groove, so that the bottom of the baffle of the baffle mechanism contacts the top of the feeding plate. When the feeding plate moves inward again, the baffle of the baffle mechanism will block the flattened aluminum coil from moving inward to complete the discharge and start the next recycling process. Finally, the flattened aluminum coil is packaged and recycled.

[0013] Beneficial effects: The aluminum coil head and tail recycling device with surface defects described in this utility model realizes the automated feeding and positioning of the aluminum coil head and tail by setting up components such as an L-shaped pusher plate, a feeding plate, a hydraulic cylinder, a transmission mechanism and a mounting frame. The device uses the driving force of the hydraulic cylinder, combined with the gear and belt drive in the transmission mechanism, as well as the rack on the L-shaped pusher plate and the feeding plate, to automatically push the aluminum coil head and tail from the initial position to the processing area without manual handling. This not only significantly improves work efficiency, but also effectively reduces the safety risks of operators and avoids physical fatigue and muscle damage caused by frequent contact with and movement of heavy aluminum coils.

[0014] In this utility model, the aluminum coil head and tail recycling device with surface defects is equipped with components such as a hydraulic cylinder, an upper pressure plate, and a material blocking mechanism. This enables the automated flattening of the aluminum coil head and tail. The upper pressure plate driven by the hydraulic cylinder can press the aluminum coil head and tail from a circular coil shape to a flat coil shape, thereby reducing the volume and facilitating subsequent transportation and storage. At the same time, the material blocking mechanism can effectively prevent the displacement of the aluminum coil head and tail during the flattening process, ensuring the stability and accuracy of the flattening process. When the feeding plate moves, the material blocking mechanism can automatically rise and fall to realize the smooth feeding and unloading of the aluminum coil, further improving the automation level of the device.

[0015] In this utility model, the device for recycling the head and tail of aluminum coils with surface defects optimizes the movement stability of the feeding plate and the positioning accuracy of the aluminum coil by setting up components such as T-shaped limiting grooves, T-shaped limiting blocks, support blocks, locking grooves, connecting plates, limiting rods and tension springs. These components together constitute the limiting and resetting mechanism of the feeding plate, which can maintain the stable movement of the feeding plate during the feeding process and automatically reset after flattening, preparing for the next feeding.

[0016] In this invention, by setting up components such as an L-shaped pusher plate, a feeding plate, a hydraulic cylinder, a transmission mechanism, and a mounting frame, the automated feeding and positioning of the aluminum coil head and tail is achieved. This device utilizes the driving force of the hydraulic cylinder, combined with gear and pulley transmission in the transmission mechanism, and racks on the L-shaped pusher plate and the feeding plate, to automatically push the aluminum coil head and tail from their initial position to the processing area, eliminating the need for manual handling. This significantly improves work efficiency and effectively reduces the safety risks for operators, avoiding physical fatigue and muscle injury caused by frequent contact with and movement of heavy aluminum coils. By setting up components such as a second hydraulic cylinder, an upper pressure plate, and a blocking mechanism, the automated flattening of the aluminum coil head and tail is achieved. The upper pressure plate driven by the second hydraulic cylinder can flatten the aluminum coil head and tail. The aluminum coil is compressed from a circular shape to a flat shape, reducing its volume and facilitating subsequent transportation and storage. Simultaneously, the design of the material-stopping mechanism effectively prevents displacement of the aluminum coil's head and tail during flattening, ensuring stability and accuracy. When the feeding plate moves, the material-stopping mechanism automatically rises and falls, allowing for smooth feeding and unloading of the aluminum coil, further improving the automation level of the device. Furthermore, by incorporating components such as T-shaped limit grooves, T-shaped limit blocks, support blocks, locking grooves, connecting plates, limit rods, and tension springs, the movement stability of the feeding plate and the positioning accuracy of the aluminum coil are optimized. These components together constitute the limiting and resetting mechanism of the feeding plate, maintaining stable movement during feeding and automatically resetting after flattening, preparing for the next feeding cycle.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figures 1-6 A recycling device includes a base 1. An L-shaped pusher plate 2 and a feeding plate 5 are slidably connected to the top of the base 1 via a slide rail and a slide block, respectively. A hydraulic cylinder 3 is fixedly installed on one side of the base 1. One end of the piston rod of the hydraulic cylinder 3 is fixedly connected to one side of the L-shaped pusher plate 2 for pushing the L-shaped pusher plate 2 to slide on the base 1.

[0026] Mounting brackets 4 are fixedly connected to both sides of the base 1. A hydraulic cylinder 6 is fixedly installed on the top inner wall of the mounting bracket 4. An upper pressure plate 7 is fixedly connected to the bottom of the piston rod of the hydraulic cylinder 6, which is used to flatten the head and tail of the aluminum coil placed on the feeding plate 5. Sliding grooves are opened on both sides of the inner wall of the mounting bracket 4. The same baffle mechanism 8 for positioning and discharging is slidably connected in the two sliding grooves.

[0027] Hydraulic cylinder 3 and hydraulic cylinder 6 both use hydraulic cylinders with model number "Φ140 / 100-800".

[0028] Two sets of transmission mechanisms for driving the feeding plate 5 are provided on both sides of the base 1. Each transmission mechanism includes two rotating shafts 15, each rotatably connected to one side of the base 1. Gears 16 and pulleys 17 are fixedly connected to the outer circumference of each shaft 15. The two pulleys 17 are connected to the same transmission belt 18, and two gears 16 in the two sets of transmission mechanisms mesh with each other. Racks 14 are fixedly connected to both sides of the L-shaped pusher plate 2 and the feeding plate 5. The racks 14 mesh with the corresponding gears 16, allowing the L-shaped pusher plate 2 and the feeding plate 5 to move via gear transmission.

[0029] When it is necessary to recycle the head and tail ends of aluminum coils with surface defects, simply place them in the area between the L-shaped pusher plate 2 and the mounting frame 4 at the top of the base 1. Activate the hydraulic cylinder 3; its piston rod pushes the L-shaped pusher plate 2, thereby moving the head and tail ends of the aluminum coil towards the mounting frame 4. At this time, the L-shaped pusher plate 2, through the cooperation of its racks 14 on both sides and two sets of transmission mechanisms, moves the feeding plate 5 towards the L-shaped pusher plate 2 via the racks 14 on both sides of the feeding plate 5. Because the sliding plane of the L-shaped pusher plate 2 is higher than the top of the feeding plate 5, the L-shaped pusher plate 2 will eventually push the head and tail ends of the aluminum coil to the top of the feeding plate 5.

[0030] Two T-shaped limiting grooves 9 are provided on both sides of the feeding plate 5. T-shaped limiting blocks 11 are slidably connected in the T-shaped limiting grooves 9. The same support block 10 is fixedly connected to one side of the two T-shaped limiting blocks 11 located on the same side. The two support blocks 10 are provided with engaging grooves 12 on the opposite sides for positioning and discharging in cooperation with the material blocking mechanism 8.

[0031] The material-stopping mechanism 8 includes two sliders, which are slidably connected in corresponding grooves. A common baffle is fixedly connected to the side of the two sliders that are close to each other, used to prevent the aluminum coil from moving. The bottom of the slider contacts the top of the support block 10, the length of the slider is greater than the length of the baffle, and the slider is adapted to the engaging groove 12. When the slider engages in the engaging groove 12, the baffle can stably prevent the aluminum coil from moving.

[0032] The top of the base 1 has a mounting groove 23, and a reset mechanism is provided in the mounting groove 23 to disengage the slider from the engaging groove 12. The reset mechanism includes a first abutment 19, two second abutments 20, and two connecting rods 21. The top of the first abutment 19 has an inclined surface for contacting the bottom of the feeding plate 5 and pushing it to move. The first abutment 19 is slidably connected in the mounting groove 23, and the two second abutments 20 are slidably connected in their respective grooves.

[0033] Two symmetrical and through connecting holes 22 are provided on one side of the connecting rod 21. Extension shafts are fixedly connected to both sides of the first abutment 19 and the sides of the two second abutments 20 that are close to each other. The extension shafts pass through the corresponding connecting holes 22, and a limiting plate for preventing them from disengaging from the connecting rod 21 is fixedly connected to one end of the extension shaft that passes through the connecting hole 22.

[0034] Hydraulic cylinder 6 is activated, its piston rod driving the upper pressure plate 7 downwards to flatten the head and tail of the aluminum coil. Then, hydraulic cylinders 3 and 6 retract their piston rods to reset. Simultaneously, due to the transmission of the two sets of transmission mechanisms, the feeding plate 5 also moves outwards along with the support blocks 10 on both sides, and moves the flattened aluminum coil outwards through the gap at the bottom of the retaining mechanism 8. When the feeding plate 5 moves to the appropriate position, the sliders on both sides of the retaining mechanism 8 will engage downwards into the engaging grooves 12, completing the discharge and starting the next recycling process.

[0035] This application can be used in the field of aluminum coil processing, or in other fields applicable to this application.

[0036] Example 2: Reference Figures 1-6 An improvement based on Embodiment 1: A device for recycling the head and tail of aluminum coils with surface defects, which is applied to the field of aluminum coil processing. A connecting plate 13 is fixedly connected to the bottom of the support block 10. Mounting blocks are fixedly connected to both sides of the base 1. A limiting rod 24 is fixedly connected to the side of the mounting block closest to the support block 10. One end of the limiting rod 24 slides through one side of the corresponding connecting plate 13. The same tension spring 25 is fixedly connected to the side of the mounting block and the corresponding connecting plate 13 that are close to each other. The tension spring 25 is sleeved on the outer circumference of the limiting rod 24 to reset the support block 10.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
