Description

Technical Field

[0001] This invention belongs to the field of metal material recycling technology, and relates to a metal waste recycling device, particularly a waste recycling device for copper strip trimming and shaping. Background Technology

[0002] Copper strip is an important non-ferrous metal material, widely used in various sectors of the national economy, including power, electronics, aviation, aerospace, shipbuilding, metallurgy, transportation, textiles, and construction. During the production and processing of copper strip, after processes such as ingot heating, hot rolling, milling, rough rolling, edge trimming, annealing, surface cleaning, finish rolling, and shearing, burrs and flash will appear on the edges of the copper strip, requiring trimming. This trimming and shaping process generates a large amount of copper strip scrap (i.e., waste material). This waste material is a new resource generated during industrial production and has high reuse value.

[0003] According to the search, a copper strip processing trimming device disclosed in Chinese patent literature [Announcement No.: CN209550721U] collects the waste generated during trimming by setting up a waste bin in the device. However, this method only achieves simple waste collection and fails to effectively process and reuse the waste. The collected waste still needs to be manually transported and processed, which is labor-intensive and has low production efficiency.

[0004] For example, the copper strip waste edge recycling device disclosed in Chinese patent literature [Announcement No.: CN202754618U] uses a take-up reel drive device to achieve the coil recycling of waste edges. Although this method facilitates the collection and transportation of waste materials, it still has the following shortcomings: First, the waste edges are large in volume after being coiled, occupying a lot of space and making storage and transportation inconvenient; second, the coiled waste materials still need to go through sorting, crushing and other processes before they can be reused, which is a long process and costly.

[0005] In summary, existing technologies generally suffer from problems such as long recycling processes, high costs, high labor intensity, and low production efficiency, making it impossible to complete continuous recycling and direct utilization of waste materials online during the trimming and shaping process. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a waste recycling device for copper strip trimming and shaping. The technical problem to be solved by this invention is: how to achieve continuous online recycling and direct utilization of waste materials during the copper strip trimming and shaping process.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A device for recycling waste materials used in copper strip trimming and shaping includes a frame, a compaction and forming component and a crushing component fixedly mounted on the top of the frame, and a material guiding component fixedly mounted on the top of the crushing component;

[0009] The material guiding assembly includes a rotating shaft and a first rotary motor fixed at one end of the feeding hopper. The output shaft of the first rotary motor is fixed with a main rotating shaft. Both the main rotating shaft and the rotating shaft are fixed with pulleys at the other end. A transmission belt is fixed between the two pulleys. A guide roller is sleeved and fixed on the outer wall of the main rotating shaft, and a rubber roller is sleeved and fixed on the outer wall of the rotating shaft.

[0010] The crushing assembly includes a crushing shell fixed to the top of the feeding box, a feeding funnel fixed inside the top of the crushing shell, and two crushing rollers rotatably connected inside the feeding box. Gears are fitted and fixed on the outer cylindrical surface of one end of each of the two crushing rollers, and the two gears are meshed together. A second rotary motor is fixed to the outer wall of one end of the feeding box, and the output end of the second rotary motor is fixed to one of the crushing rollers.

[0011] The compaction molding assembly includes a molding box, a molding mold is fixedly installed inside the molding box, and a compaction push plate is slidably connected inside the molding mold. A hydraulic cylinder is fixedly installed inside the molding box, and a hydraulic rod is slidably connected inside the hydraulic cylinder, with the other end of the hydraulic rod fixedly connected to the compaction push plate.

[0012] The working principle of this invention is as follows: A first rotary motor drives the main rotating shaft and guide roller to rotate, which in turn drives the rotating shaft and rubber roller to rotate synchronously via a pulley and transmission belt. The copper strip scrap enters the feeding funnel and is guided into the crushing shell under the traction of the guide roller and rubber roller. At this time, a second rotary motor drives two crushing rollers to rotate in opposite directions through gears, crushing the scrap into small pieces. The small pieces are then compacted and shaped in the forming box by a hydraulic cylinder pushing a hydraulic rod and a compaction pusher plate in the forming mold. Thus, this copper strip trimming and shaping waste recycling device integrates the guiding traction, crushing, and compaction forming processes into one, enabling continuous recycling and direct forming of waste in the copper strip trimming and shaping production line online. It eliminates the need to transport the waste to a separate smelting workshop for processing, significantly shortening the waste recycling process and time, while avoiding the high-energy-consuming smelting process, and significantly reducing the energy consumption and processing costs of waste recycling.

[0013] The bottom of the forming box is slidably connected to a feeding template, and a third rotary motor is fixedly installed at the bottom of the forming box. A lead screw is fixedly installed at the output end of the third rotary motor. The lead screw is screwed into the feeding template. A limiting rod is fixedly installed at the bottom of the forming box. The limiting rod is slidably connected to the feeding template.

[0014] With the above structure, the screw is driven to rotate by the third rotary motor, and the unloading template slides under the drive of the screw and the guide of the limit rod, so as to realize the opening and closing of the bottom discharge port of the forming mold, so that the formed material block is automatically unloaded without manual opening and closing, which improves the continuity of material discharge.

[0015] A pulse generator is fixedly installed at the bottom of the molding box, and a sleeve is fixedly installed at the output end of the pulse generator. A piston slides inside the sleeve, and a drive rod is fixedly installed at one end of the piston. An impact block is fixedly installed at the other end of the drive rod. A return spring is fixedly installed on the inner wall of one end of the sleeve, and the other end of the return spring is fixedly connected to the piston.

[0016] Using the above structure, pulse pressure is input into the sleeve by the pulse machine, which pushes the piston and drive rod to compress the return spring and cause the impact block to strike the forming copper block on the unloading template. The impact assists the forming copper block to be demolded, and the return spring drives the impact block to return to its original position, preventing the material block from sticking to the mold and ensuring continuous unloading.

[0017] The rotating shaft is hollow inside. Multiple first air passage holes are opened inside one end of the rotating shaft, and multiple second air passage holes are opened in the middle of the rotating shaft. A sealing sleeve is rotatably connected to the outer cylindrical surface of one end of the rotating shaft. An air injection pump is fixedly installed on the outer wall of one end of the feeding funnel, and the output end of the air injection pump is fixedly connected to the sealing sleeve.

[0018] With the above structure, an air pump delivers airflow to the sealing sleeve. The gas enters the rotating shaft through the first air passage and is ejected along the second air passage, which in turn squeezes the rubber roller to expand, increasing the radius of the rubber roller. This changes the gap between the rubber roller and the guide roller, keeping the tension of the waste material within a preset range, thereby ensuring the stability of the material guide.

[0019] The bottom of one side of the feeding box has a discharge port, and a guide plate is fixed inside the discharge port.

[0020] With the above structure, the crushed material falls onto the guide plate and is discharged through the outlet. The guide plate ensures that the crushed material flows smoothly to the feed pipe inlet, avoiding material accumulation and spillage, and improving material conveying efficiency.

[0021] It also includes a material conveying assembly, which includes a first material conveying blower. The inlet end of the first material conveying blower is fixedly provided with an inlet pipe, and the other end of the inlet pipe is fixedly connected to the outlet. The outlet end of the first material conveying blower is fixedly connected to the forming box.

[0022] With the above structure, the first material conveying fan operates to draw the crushed material at the outlet through the feed pipe and pneumatically convey it to the forming box, thereby achieving closed conveying of the crushed material, improving the working environment and enhancing the automation of feeding.

[0023] A second material conveying fan is fixedly installed on one side of the molding box, and the material conveying end of the second material conveying fan is fixedly connected to the feed pipe.

[0024] With the above structure, the overflow or excess fragments in the forming box are sucked up by the second material conveying fan and sent back into the feed pipe through its conveying end to merge with the mainstream material, so as to realize the recycling of fragments and reduce material waste.

[0025] A filter plate is fixed to the top of the forming box, and a collection box is fixed to the top of the frame base plate.

[0026] With the above structure, the dust-laden gas in the molding box is filtered by the filter plate, and the trapped copper shavings fall into the collection box for collection. Clean gas is discharged, and fine copper shavings are recovered, reducing environmental pollution and improving raw material utilization.

[0027] The meshing depth between the two crushing rollers is 2mm-8mm, and the crushing gap is 0.5mm-5mm.

[0028] With the above structure, the waste edge material is bitten into the crushing roller with a meshing depth of 2-8mm and torn through the crushing gap of 0.5-5mm to obtain crushed material of appropriate size and uniformity, which improves the density and molding quality of the subsequent compacted blocks.

[0029] Compared with existing technologies, this waste recycling device for copper strip trimming and shaping has the following advantages:

[0030] 1. This invention uses a first rotary motor to drive the main rotating shaft and guide rollers to rotate. A pulley and transmission belt drive the rotating shaft and rubber rollers to rotate synchronously. Copper strip scrap is drawn into the feeding hopper and introduced into the crushing shell by the guide rollers and rubber rollers. At this time, a second rotary motor drives two crushing rollers to rotate in opposite directions via gears, crushing the scrap into small pieces. These small pieces are then compacted in the forming box by a hydraulic cylinder pushing a hydraulic rod and a compaction plate within the forming mold. This copper strip trimming and shaping waste recycling device integrates guiding, crushing, and compaction processes into one unit. It enables continuous online recycling and direct forming of waste in the copper strip trimming and shaping production line, eliminating the need to transport waste to a separate smelting workshop for processing. This significantly shortens the waste recycling process and time, while avoiding the energy-intensive smelting process, thus significantly reducing energy consumption and processing costs.

[0031] 2. In this invention, the lead screw is driven to rotate by a third rotary motor, and the unloading template slides under the drive of the lead screw and the guidance of the limiting rod, so as to realize the opening and closing of the discharge port at the bottom of the forming mold, so that the formed material block is automatically unloaded without manual opening and closing, thus improving the continuity of material discharge.

[0032] 3. In this invention, pulse pressure is input into the sleeve by a pulse machine, which pushes the piston and drive rod to compress the return spring and cause the impact block to strike the formed copper block on the unloading template. The impact assists the unloading of the formed copper block. The return spring drives the impact block to return to its original position, preventing the material block from sticking to the mold and ensuring continuous unloading.

[0033] 4. In this invention, an air pump delivers airflow to the sealing sleeve. The gas enters the interior of the rotating shaft through the first air passage and is ejected along the second air passage, thereby squeezing the rubber roller to expand, increasing the radius of the rubber roller, thereby changing the gap between the rubber roller and the guide roller, adjusting the clamping force on the waste material, and maintaining the tension of the waste material within a preset range, thus ensuring the stability of the guiding material.

[0034] 5. The first material conveying fan operates to draw the broken material from the outlet through the feed pipe and pneumatically convey it to the forming box, realizing the closed conveying of the broken material, improving the working environment and enhancing the automation of feeding. The second material conveying fan sucks out the overflow or excess broken material in the forming box and sends it back into the feed pipe through its conveying end, where it merges with the mainstream material, realizing the recycling of broken material and reducing material waste.

[0043] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0044] like Figures 1-7 As shown, the waste recycling device for copper strip trimming and shaping includes a frame 501, a compaction and forming component and a crushing component are fixedly installed on the top of the frame 501, and a material guiding component is fixedly installed on the top of the crushing component.

[0045] The material guiding assembly includes a first rotary motor 102 fixed to one end of a discharge hopper 101 and a rotating shaft 105. The output shaft of the first rotary motor 102 is fixed to a main rotating shaft 103. Both the main rotating shaft 103 and the rotating shaft 105 are fixed to the other end of a pulley 106. A transmission belt 107 is fixed between the two pulleys 106. A guide roller 104 is sleeved and fixed to the outer wall of the main rotating shaft 103, and a rubber roller 110 is sleeved and fixed to the outer wall of the rotating shaft 105.

[0046] The crushing assembly includes a crushing shell 201 fixed to the top of the feeding box 202, a feeding hopper 101 fixed inside the top of the crushing shell 201, and two crushing rollers 206 rotatably connected inside the feeding box 202. Gears 207 are sleeved and fixed on the outer cylindrical surface of one end of each of the two crushing rollers 206, and the two gears 207 are meshed. A second rotary motor 205 is fixed to the outer wall of one end of the feeding box 202, and the output end of the second rotary motor 205 is fixedly connected to one of the crushing rollers 206.

[0047] The compaction molding assembly includes a molding box 301, a molding mold 302 fixed inside the molding box 301, and a compaction pusher 305 slidably connected inside the molding mold 302. A hydraulic cylinder 303 is fixed inside the molding box 301, and a hydraulic rod 304 is slidably connected inside the hydraulic cylinder 303, with the other end of the hydraulic rod 304 fixedly connected to the compaction pusher 305.

[0048] The first rotary motor 102 drives the main rotating shaft 103 and guide roller 104 to rotate, which in turn drives the rotating shaft 105 and rubber roller 110 to rotate synchronously via pulley 106 and transmission belt 107. The copper strip scrap enters the feeding funnel 101 and is guided into the crushing shell 201 under the traction of the guide roller 104 and rubber roller 110. At this time, the second rotary motor 205 drives the two crushing rollers 206 to rotate in opposite directions via gear 207, crushing the scrap into small pieces. The small pieces are pushed by the hydraulic cylinder 303 to the hydraulic rod in the forming box. 304 and the compaction pusher 305 compact the scrap material in the forming mold 302, thereby integrating the guiding traction, crushing and compaction forming processes into one, so that the waste recycling device for copper strip trimming and shaping can complete the continuous recycling and direct forming of waste online in the copper strip trimming and shaping production line without the need to transfer the waste to a separate smelting workshop for processing, which greatly shortens the waste recycling process and time, while avoiding the high-energy-consuming smelting process, and significantly reducing the energy consumption and processing cost of waste recycling.

[0049] The bottom of the forming box 301 is slidably connected to the unloading template 330, and the bottom end of the forming box 301 is fixedly provided with a third rotary motor 310. The output end of the third rotary motor 310 is fixedly provided with a lead screw 320, which is screwed and connected to the unloading template 330. The bottom end of the forming box 301 is fixedly provided with a limiting rod 340, which is slidably connected to the unloading template 330.

[0050] In this embodiment, the lead screw 320 is driven to rotate by the third rotary motor 310, and the unloading template 330 slides under the drive of the lead screw 320 and the guide of the limiting rod 340, so as to realize the opening and closing of the bottom discharge port of the molding mold 302, so that the molded material block is automatically unloaded without manual opening and closing, which improves the continuity of material discharge.

[0051] A pulse machine 401 is fixedly installed at the bottom of the molding box 301, and a sleeve 402 is fixedly installed at the output end of the pulse machine 401. A piston 404 slides inside the sleeve 402, and a drive rod 405 is fixedly installed at one end of the piston 404. An impact block 406 is fixedly installed at the other end of the drive rod 405. A return spring 403 is fixedly installed on the inner wall of one end of the sleeve 402, and the other end of the return spring 403 is fixedly connected to the piston 404.

[0052] In this embodiment, pulse pressure is input into the sleeve 402 by the pulse machine 401, which pushes the piston 404 and the drive rod 405 to compress the reset spring 403 and cause the impact block 406 to impact the formed copper block on the unloading template 330. The impact assists the unloading of the formed copper block. The reset spring 403 drives the impact block 406 to return to its original position, preventing the material block from sticking to the mold and ensuring continuous unloading.

[0053] The rotating shaft 105 is hollow inside. Multiple first air passage holes 108 are opened inside one end of the rotating shaft 105, and multiple second air passage holes 109 are opened in the middle of the rotating shaft 105. A sealing sleeve 130 is rotatably connected to the outer cylindrical surface of one end of the rotating shaft 105. An air injection pump 120 is fixedly installed on the outer wall of one end of the feeding funnel 101, and the output end of the air injection pump 120 is fixedly connected to the sealing sleeve 130.

[0054] In this embodiment, airflow is delivered to the sealing sleeve 130 by the air pump 120. The gas enters the interior of the rotating shaft 105 through the first air passage 108 and is ejected along the second air passage 109, thereby squeezing the rubber roller 110 to expand, increasing the radius of the rubber roller 110, thereby changing the gap between the rubber roller 110 and the guide roller 104, so that the tension of the waste material is maintained within a preset range, thereby ensuring the stability of the material guide.

[0055] A discharge port 203 is provided on the bottom side of the feeding box 202, and a guide plate 204 is fixed inside the discharge port 203.

[0056] In this embodiment, the crushed material falls onto the guide plate 204 and is discharged through the outlet 203. The guide plate 204 guides the material to ensure that it flows smoothly to the inlet of the feed pipe 306, avoiding material accumulation and spillage, and improving material conveying efficiency.

[0057] It also includes a material conveying assembly, which includes a first material conveying blower 307. The inlet end of the first material conveying blower 307 is fixedly provided with a feed pipe 306, and the other end of the feed pipe 306 is fixedly connected to the outlet 203. The outlet end of the first material conveying blower 307 is fixedly connected to the forming box 301.

[0058] In this embodiment, the first material conveying fan 307 operates to draw the crushed material at the outlet 203 into the feed pipe 306 and pneumatically convey it to the forming box 301, thereby achieving closed conveying of the crushed material, improving the working environment and enhancing the automation of feeding.

[0059] A second material conveying fan 308 is fixedly installed on one side of the forming box 301, and the material conveying end of the second material conveying fan 308 is fixedly connected to the feed pipe 306.

[0060] In this embodiment, the second material conveying fan 308 sucks up the overflow or excess fragments in the forming box 301 and sends them back into the feed pipe 306 through its conveying end, so as to merge with the mainstream material, realize the recycling of fragments, and reduce material waste.

[0061] A filter plate 309 is fixedly installed at the top of the forming box 301, and a collection box 502 is fixedly installed at the top of the bottom plate of the frame 501.

[0062] In this embodiment, the dust-laden gas in the molding box 301 is filtered by the filter plate 309, and the trapped copper shavings fall into the collection box 502 for collection. Clean gas is discharged, and fine copper shavings are recovered, reducing environmental pollution and improving raw material utilization.

[0063] The meshing depth between the two crushing rollers 206 is 2mm-8mm, and the crushing gap is 0.5mm-5mm.

[0064] In this embodiment, the waste edge material is bitten into the crushing roller 206 at a meshing depth of 2-8mm and torn through a crushing gap of 0.5-5mm to obtain appropriately sized and uniform fragments, thereby improving the density and molding quality of the subsequent compacted blocks.

[0065] Working principle of the invention:

[0066] During operation, the first rotary motor 102 starts, driving the main rotating shaft 103 and guide roller 104 to rotate. The main rotating shaft 103 drives the rotating shaft 105 and rubber roller 110 to rotate synchronously via pulley 106 and transmission belt 107. The waste material generated from copper strip trimming is guided between guide roller 104 and rubber roller 110, and under the clamping and traction of the two rollers, it enters the feeding funnel 101 and falls into the crushing shell 201 along the feeding funnel 101. After the waste material enters the crushing assembly, the second rotary motor 205 starts, driving a crushing roller 206 fixed to it to rotate. The crushing roller 206 drives another crushing roller 206 to rotate in opposite directions via two meshing gears 207. The two crushing rollers 206 squeeze and shear the waste material with a meshing depth of 2mm-8mm and a crushing gap of 0.5mm-5mm. The waste material is crushed into granular or flaky fragments. The crushed fragments fall onto the guide plate 204 under gravity and are discharged through the discharge port 203. The first material conveying fan 307 operates, generating negative pressure in the feed pipe 306, which draws the fragments from the discharge port 203 into the feed pipe 306 and through... The first material conveying blower 307 pneumatically conveys the material to the forming box 301 at its discharge end. After entering the forming box 301, the crushed material falls into the inner cavity of the forming mold 302. The hydraulic cylinder 303 is filled with oil, pushing the hydraulic rod 304 to extend. The hydraulic rod 304 drives the compaction pusher 305 to move forward in the forming mold 302, forcefully squeezing the crushed material into the forming cavity of the forming mold 302. Under high pressure, the crushed material is compacted into recycled copper blocks. After compaction and forming are completed, the third rotary motor 310 starts, driving the lead screw 320 to rotate. The feeding template 330 is driven by the spiral of the lead screw 320. The moving and limiting rod 340 slides open under the sliding guide, opening the discharge port at the bottom of the forming mold 302. The pulse machine 401 inputs pulse airflow into the sleeve 402, pushing the piston 404 to slide along the inner wall of the sleeve 402. The piston 404 drives the drive rod 405 and the impact block 406 to extend and compress the return spring 403. The impact block 406 impacts the forming copper block on the unloading template 330, causing it to be removed from the forming mold 302. After the pulse pressure is released, the return spring 403 rebounds, pushing the piston 404, drive rod 405 and impact block 406 to reset.

[0067] During the material feeding process, the air pump 120 delivers airflow to the sealing sleeve 130. The gas enters the hollow cavity inside the rotating shaft 105 through the first air passage 108 and is then ejected through the second air passage 109, causing the rubber roller 110 to expand and its radius to increase, thereby changing the gap between the rubber roller 110 and the guide roller 104 and adjusting the clamping force on the waste material.

[0068] During the material conveying and molding process, the second material conveying fan 308 operates, sucking up the excess fragments that have spilled or not been compacted in the molding box 301, and sending them back into the feed pipe 306 through its conveying end, where they are incorporated into the mainstream material for recycling. The dust-laden gas in the molding box 301 is filtered by the filter plate 309, and the trapped copper shavings fall into the collection box 502 for collection, while the clean gas is discharged.

[0069] In summary, by integrating the guiding, crushing, and compaction processes into one unit, continuous recycling and direct molding of waste materials can be completed online in the copper strip trimming and shaping production line. There is no need to transfer the waste materials to a separate smelting workshop for processing, which greatly shortens the process and time of waste material recycling and utilization. At the same time, it avoids the high-energy-consuming smelting process and significantly reduces the energy consumption and processing costs of waste material recycling and utilization.
