Description

Technical Field

[0001] This invention relates to the field of waste copper dismantling technology, and more specifically to a crushing mechanism for waste copper dismantling. Background Technology

[0002] Scrap copper dismantling is a crucial step in resource recycling. It specifically refers to the process of separating and crushing copper components from copper-containing waste materials such as waste cables, motor windings, copper foil, and copper briquettes, using physical or mechanical methods, to obtain high-purity recycled copper raw materials. Its core pretreatment step relies on a crushing mechanism to shred, crush, or cut the copper-containing waste materials, providing a uniform particle size base for subsequent sorting and smelting. Currently, the mainstream scrap copper crushing equipment in the industry mostly adopts single-shaft or double-shaft shredders, roller crushers, and other structures, which achieve material crushing through blade cutting and roller compression, and has been widely used in the field of resource recycling.

[0003] Currently, the industry commonly uses crushing and cutting equipment for scrap copper dismantling operations. These equipment use rotating blades in conjunction with fixed blades on a frame as the core working components. They have a wide range of applications. Conventional equipment has an independent layout for feeding, conveying, crushing, and cutting, with each functional mechanism having its own power drive component. This results in poor overall power matching, high energy consumption, and a large overall installation space requirement. Furthermore, during the crushing process, the material feeding posture is chaotic and disorderly, which can easily lead to material being suspended in mid-air or blades running without material. This results in poor continuity of crushing operations, and hard debris can easily accumulate in the gaps between the blades. Long-term operation can cause abnormal wear on the blades, requiring frequent shutdowns for manual inspection and cleaning. This makes it difficult to meet the needs of large-scale continuous scrap copper dismantling operations. Summary of the Invention

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] Example: Please see Figures 1 to 8 A crushing mechanism for dismantling waste copper includes a housing 1, a base 5, a controller 6, a motor 14, a fixed blade 19, a moving blade 18, a screen 24, and a crushing shaft 16. A drive wheel 25 and a pinion 17 are fixedly connected to the surface of the crushing shaft 16 away from the motor 14. A feeding roller assembly is connected to the inner wall of the housing 1 near the feed inlet via bearings. A transmission mechanism is provided on the outer side of the housing 1, diagonally above the drive wheel 25. The drive wheel 25 is connected to the feeding roller assembly via the transmission mechanism. A reduction gear 13 meshes with the outer surface of the pinion 17. A connecting rod 41 is fixedly connected to the side of the reduction gear 13 near the housing 1. An active pressure ball 42 is fixedly connected to the end of the connecting rod 41 away from the reduction gear 13. A pressing plate 28 is rotatably connected to the surface of the housing 1 on the side of the active pressure ball 42 via a pin shaft. An arc groove 29 is provided on the surface of the pressing plate 28. A pressing switch 30 is connected to the surface of the housing 1 on the side of the pressing plate 28. A pressing plate 21 is provided inside the housing 1 on the side of the feed inlet. The end of the crushing shaft 16 away from the motor 14 extends to the outside of the housing 1. The outer surface of the active pressure ball 42 is slidably connected to the inside of the arc groove 29. The surface of the pressing plate 28 is in contact with the outer surface of the pressing switch 30. An electric telescopic rod 4 is fixedly connected to the surface of the housing 1. The telescopic end of the electric telescopic rod 4 extends into the inside of the housing 1. The telescopic end of the electric telescopic rod 4 is fixedly connected to the surface of the pressing plate 21. The controller 6 is electrically connected to the electric telescopic rod 4 through a wire. The feeding roller assembly includes a first feeding roller 39, a second feeding roller 9, a third feeding roller 8, and a fourth feeding roller 7. The two end surfaces of the first feeding roller 39, the two end surfaces of the second feeding roller 9, the two end surfaces of the third feeding roller 8, and the two end surfaces of the fourth feeding roller 7 are all connected to the inner wall of the housing 1 through bearings. One end of the first feeding roller 39, one end of the second feeding roller 9, one end of the third feeding roller 8, and one end of the fourth feeding roller 7 all extend to the outer side of the housing 1.

[0021] Working principle: The motor 14 is installed on the outer wall of the housing 1 by a fixed connection. The output end of the motor 14 is connected to the crushing shaft 16 by a fixed connection. After the motor 14 is started, it can directly drive the crushing shaft 16 to rotate stably, providing a unified power source for the whole machine.

[0022] The crushing shaft 16 drives the drive wheel 25 and the pinion 17 to rotate synchronously through a fixed connection, so that the drive wheel 25 and the pinion 17 maintain the same speed and movement pace with the crushing shaft 16, thereby achieving synchronous power distribution.

[0023] The drive wheel 25 is connected to the feeding roller group through the transmission mechanism, which can transmit the rotational power of the crushing shaft 16 to the feeding roller group, so that the feeding roller group and the crushing shaft 16 keep running in linkage. There is no need to add an additional feeding drive motor, which simplifies the overall structure of the machine.

[0024] The pinion 17 engages with the reduction gear 13 via a meshing connection. Driven by the pinion 17, the reduction gear 13 rotates stably at a speed lower than that of the crushing shaft 16, achieving a speed reduction and torque increase effect, and ensuring smooth and reliable subsequent triggering actions.

[0025] The reduction gear 13 drives the connecting rod 41 to rotate through a fixed connection. The connecting rod 41 drives the active pressure ball 42 to make continuous circular motion through the fixed connection, so that the active pressure ball 42 forms a periodic triggering action.

[0026] During rotation, the active pressure ball 42 extends into the arc-shaped groove 29 of the pressing plate 28 and forms a sliding connection with the inner wall of the arc-shaped groove 29. The active pressure ball 42 can slide smoothly along the arc-shaped groove 29 and push the pressing plate 28 to rotate around the pin.

[0027] During the swinging process, the pressing plate 28 periodically touches the pressing switch 30, which stably triggers the pressing switch 30 and outputs an electrical signal, thereby realizing the precise conversion between mechanical motion and electrical signal.

[0028] The push switch 30 transmits a signal to the controller 6 via a wire. The controller 6 controls the electric telescopic rod 4 to extend and retract through a preset program. The electric telescopic rod 4 drives the pressure plate 21 to move up and down through a fixed connection, pressing and pushing the waste copper material at the feed inlet to prevent the material from being suspended, piling up, or not being fed.

[0029] The first feeding roller 39, the second feeding roller 9, the third feeding roller 8, and the fourth feeding roller 7 are all rotatably connected to the inner wall of the housing 1 through bearings, allowing each feeding roller to rotate freely and smoothly, reducing transmission resistance and wear.

[0030] The aforementioned fixed connections can be achieved using conventional fixing methods such as bolt connections, welding, interference fits, and key connections. Rotary connections can be achieved using methods such as deep groove ball bearings, needle roller bearings, and bushing fits. Sliding connections can be achieved using structures such as guide grooves, rollers, and slide rails.

[0031] It should be noted that meshing connection is the most commonly used form of power transmission in gear transmission. It features precise transmission ratio, high load capacity, and stable motion, and is suitable for high-precision synchronous transmission scenarios.

[0032] Please see Figures 1 to 8 The transmission mechanism includes a reduction wheel 10, two first driven wheels 31, two second driven wheels 32, and two third driven wheels 33. The outer surface of one end of the first feeding roller 39 is connected to the inner wall of the reduction wheel 10. The outer surfaces of one end of the first feeding roller 39 and one end of the second feeding roller 9 are respectively connected to the inner walls of the two first driven wheels 31. The outer surfaces of one end of the second feeding roller 9 and the third feeding roller 8 are respectively connected to the inner walls of the two second driven wheels 32. The outer surfaces of the third feeding roller 8 and the fourth feeding roller 7 are both connected to the inner walls of the two third driven wheels 33. A first belt 11 is connected between the driving wheel 25 and the reduction wheel 10. A second belt 34 is connected to the interior of the two first driven wheels 31, the interior of the two second driven wheels 32, and the interior of the two third driven wheels 33. A bearing seat 40 is connected to the surface of the housing 1 on one side of the mounting ring 38. The inner ring of the bearing seat 40 is connected to the mounting shaft 12. The outer surface of the mounting shaft 12 is connected to the inner ring of the reduction gear 13. A protective shell 2 is bolted to the surface of the housing 1. The surface of the housing 1 is bolted to the motor 14. The reduction gear 13 and the second belt 34 are both located inside the protective shell 2.

[0033] Working principle: The drive wheel 25 is connected to the reduction wheel 10 through the first belt 11. When the drive wheel 25 rotates with the crushing shaft 16, it can drive the reduction wheel 10 to rotate synchronously through the first belt 11, so as to realize the smooth transmission of power.

[0034] The reduction wheel 10 and the driving wheel 25 form a diameter difference fit, so that the reduction wheel 10 rotates at a lower speed than the driving wheel 25, thereby achieving deceleration at the feeding end and matching the feeding speed with the crushing speed to avoid feeding too fast or too slow.

[0035] The first feeding roller 39 is connected to the reduction wheel 10 by a fixed connection. The reduction wheel 10 can directly drive the first feeding roller 39 to rotate stably and complete the primary feeding action.

[0036] The first feeding roller 39 drives the second feeding roller 9 to rotate through the first driven wheel 31 and the second belt 34. The second feeding roller 9 drives the third feeding roller 8 to rotate through the second driven wheel 32 and the second belt 34. The third feeding roller 8 drives the fourth feeding roller 7 to rotate through the third driven wheel 33 and the second belt 34, so that the multi-stage feeding rollers can operate synchronously and continuously in the same direction.

[0037] Multiple driven pulleys cooperate with the second belt 34 to keep each feeding roller at the same linear speed, ensuring smooth material conveying without slippage or jamming.

[0038] The bearing housing 40 is fixedly connected to the outer wall of the housing 1. The inner ring of the bearing housing 40 is rotatably connected to the mounting shaft 12, providing stable support for the mounting shaft 12.

[0039] The mounting shaft 12 is connected to the inner ring of the reduction gear 13 by a fixed connection, so that the reduction gear 13 can rotate stably around the mounting shaft 12 and avoid radial runout or axial movement of the reduction gear 13.

[0040] The protective shell 2 is fixed to the outer wall of the shell 1 by bolt connection, completely covering the reduction gear 13, the second belt 34 and each driven pulley inside, forming a closed protective space to prevent dust from entering the transmission components, while avoiding operators from contacting moving parts, thus improving the safety of equipment use.

[0041] Belt drives can be replaced by conventional transmission methods such as sprocket and chain drives, synchronous belt drives, and cylindrical gear drives. Bolt connections can be achieved using snap-fit ​​connections, screw connections, flange connections, etc.

[0042] Please see Figures 1 to 8 A mounting ring 38 is fixedly connected to one side of the reduction gear 13 near the housing 1. A connecting rod 41 is located outside the mounting ring 38. A plurality of balance bars 37 are fixedly connected to one end of the mounting ring 38 near the housing 1. A sliding limit ball 36 is fixedly connected to one end of the balance bar 37 away from the mounting ring 38. An annular groove 26 corresponding to the mounting ring 38 is opened on the surface of the housing 1. Each sliding limit ball 36 penetrates into the interior of the annular groove 26. The inner wall of the annular groove 26 has two inner annular grooves 27, and the interior of each inner annular groove 27 is slidably connected to the interior of the sliding limit ball 36. The bottom surface of the housing 1 has a discharge port 23, and the bottom surface of the housing 1 is connected to the upper surface of the base 5. The connection end of the controller 6 is fixedly connected to the upper surface of the base 5. The crushing shaft 16 is connected to the inner wall of the housing 1 through a bearing. The output end of the motor 14 is connected to the end of the crushing shaft 16 away from the reduction gear 13. The fixed blade 19 is fixedly connected to the inner wall of the housing 1 through bolts. The moving blade 18 is fixedly connected to the surface of the crushing shaft 16 through bolts. The controller 6 is electrically connected to the motor 14 through wires.

[0043] Working principle: The reduction gear 13 drives the mounting ring 38 to rotate synchronously through a fixed connection. The mounting ring 38 rotates concentrically and stably with the reduction gear 13, providing a uniform mounting base for the balance bar 37.

[0044] The mounting ring 38 is connected to multiple balance bars 37 by a fixed connection. The multiple balance bars 37 are evenly distributed along the circumference of the mounting ring 38, so that the reduction gear 13 is subjected to balanced force and rotates smoothly when it rotates.

[0045] The balance bar 37 drives the sliding limit ball 36 to rotate through a fixed connection. The sliding limit ball 36 extends into the annular groove 26 opened on the surface of the housing 1 and forms a sliding connection with the annular groove 26.

[0046] Two sets of inner annular grooves 27 are opened on the inner wall of the annular groove 26. The sliding limiting ball 36 is inserted into the inner annular groove 27 and forms a sliding connection with the inner annular groove 27, so as to realize the radial and axial limiting of the reduction gear 13 and prevent the reduction gear 13 from deviating, shaking or falling off during operation.

[0047] A discharge port 23 is provided on the bottom surface of the casing 1. The discharge port 23 is located below the screen 24. The crushed material can be smoothly discharged from the machine through the discharge port 23, avoiding material accumulation and machine stalling.

[0048] The base 5 supports the housing 1 through a fixed connection, ensuring the machine is placed stably and operates without shaking. The controller 6 is fixedly installed on the base 5, facilitating operator control and wiring. The crushing shaft 16 is rotatably connected to the inner wall of the housing 1 through bearings, ensuring smooth rotation of the crushing shaft 16 with low resistance. The fixed blade 19 is fixed to the inner wall of the housing 1 through bolts, and the moving blade 18 is fixed to the crushing shaft 16 through bolts. The moving blade 18 rotates at high speed with the crushing shaft 16 and forms a shearing engagement with the fixed blade 19, continuously crushing, cutting, and shredding the waste copper material.

[0049] The controller 6 is electrically connected to the motor 14, the electric telescopic rod 4, and the push switch 30 via wires to realize the automatic control and safety protection of the whole machine.

[0050] Sliding limit connections can be achieved using structures such as roller slide rails, guide bushings, and slide block sliders, while bolt connections can be achieved using methods such as pressure plate fixing, pin fixing, and clamp fixing.

[0051] It should be noted that shearing is the core working method of waste copper crushing. The material is cut off by the relative cutting motion of the moving blade 18 and the fixed blade 19. It is particularly suitable for crushing and dismantling waste cables, copper wires, and scrap copper.

[0052] Please see Figures 1 to 8 Both ends of the screen 24 are fixedly connected to the inner wall of the housing 1 by bolts. The screen 24 is semi-circular and located at the bottom of the moving knife 18. Both ends of the screen 24 are fixedly connected with arc-shaped pads 15 that are adapted to the screen 24. The surface of each arc-shaped pad 15 is in contact with the inner wall of the housing 1.

[0053] Working principle: The screen 24 is fixedly installed on the inner wall of the housing 1 by bolt connection. The screen 24 is arranged in a semi-circular structure at the bottom of the moving knife 18, which is adapted to the rotation trajectory of the moving knife 18 to expand the contact area between crushing and screening.

[0054] Screen 24 can classify and screen the crushed material. Material that meets the particle size requirements passes through screen 24 and falls down, while material that does not meet the particle size requirements remains in the crushing chamber and continues to be sheared and crushed, ensuring uniform output particle size.

[0055] The arc-shaped pads 15 are fixedly connected to both ends of the screen 24. The arc-shaped pads 15 adopt an elastic sealing structure and form a tight contact and sealing fit with the inner wall of the shell 1 to prevent material from leaking from the gaps at the ends of the screen 24 and to avoid the direct discharge of uncrushed material.

[0056] The arc-shaped pad 15 can buffer the hard contact between the screen 24 and the housing 1, reduce vibration and noise, and extend the service life of the screen 24.

[0057] The semi-circular screen 24 can effectively prevent materials from accumulating at the bottom of the crushing chamber, allowing the materials to continuously tumble, shear, and screen under the drive of the rotating blade 18, thereby improving crushing and screening efficiency.

[0058] The screen 24 can be fixed by means of slot fixing, elastic clamping, bolt pressure plate fixing, etc., and the sealing contact can be achieved by conventional sealing structures such as rubber gasket, silicone gasket, and felt sealing.

[0059] Please see Figures 1 to 8 The two inner sidewalls of the housing 1 are provided with two limiting grooves 20 on the outer side of the pressure plate 21. Each limiting groove 20 is slidably connected to a limiting slider 22, and the outer surface of each limiting slider 22 is slidably connected to the inside of the limiting groove 20.

[0060] Working principle: Limiting grooves 20 are respectively opened on the two inner side walls of the housing 1. The limiting grooves 20 extend in the vertical direction to provide vertical movement guidance for the pressure plate 21.

[0061] A limiting slider 22 is fixedly connected to the outer wall of the pressure plate 21. The limiting slider 22 is inserted into the limiting groove 20 and forms a sliding connection with the limiting groove 20, so that the pressure plate 21 can only move up and down in the vertical direction along the limiting groove 20, thus restricting the horizontal displacement and rotation of the pressure plate 21.

[0062] The limiting groove 20 and the limiting slider 22 are symmetrically distributed on both sides of the pressure plate 21, so that the pressure plate 21 is subjected to uniform force and moves smoothly during the up and down movement, and there will be no tilting, jamming or deviation.

[0063] The limit slider 22 and the limit groove 20 are in clearance fit, which allows for smooth sliding without jamming and ensures that the pressing action of the pressure plate 21 is sensitive and reliable.

[0064] The sliding limit structure can be implemented using conventional guiding methods such as guide shaft and bushing cooperation, slide groove and roller cooperation, and linear slide rail cooperation.

[0065] Please see Figures 1 to 8 The outer surfaces of the first feeding roller 39, the second feeding roller 9, the third feeding roller 8, and the fourth feeding roller 7 are all fixedly connected with anti-slip layers 35. The first feeding roller 39, the second feeding roller 9, the third feeding roller 8, and the fourth feeding roller 7 are arranged in a gradual manner from bottom to top, and are arranged to bend upwards in sequence.

[0066] Working principle: The anti-slip layer 35 is applied to the outer surface of the first feeding roller 39, the second feeding roller 9, the third feeding roller 8, and the fourth feeding roller 7 by means of coating, bonding, or vulcanization, which increases the friction coefficient of the roller surface and improves the gripping force on loose materials such as waste copper and cables.

[0067] The anti-slip layer 35 can effectively prevent materials from slipping, spinning idly, or having insufficient feeding power during the conveying process, ensuring stable forward conveying of materials.

[0068] The first feeding roller 39, the second feeding roller 9, the third feeding roller 8, and the fourth feeding roller 7 are arranged in a gradually changing pattern from bottom to top, and are arranged to bend upwards in sequence to form an arc-shaped progressive feeding channel.

[0069] The inclined and curved feeding rollers can guide the material to be fed into the crushing chamber gradually and gently along the arc path, making the material feeding posture more regular and avoiding messy stacking, bridging, and bridging.

[0070] The arc-shaped feeding channel can gradually tighten the material, making it easier for the material to enter the shearing zone and improving the continuity and stability of crushing.

[0071] The inclined arrangement of multiple rollers can also disperse the feeding pressure, reduce the impact on individual feed rollers, and extend the service life of the feed rollers.

[0072] The anti-slip structure can be achieved by surface knurling, diamond mesh, axial ridges, sawtooth anti-slip teeth, polyurethane coating, etc. The feeding rollers can be arranged in a stepped, arc continuous, or tapering layout to achieve the same feeding effect.

[0073] In summary, during operation, the entire equipment works as follows: After the motor 14 starts, it continuously outputs power and drives the crushing shaft 16 to rotate at high speed and stably. The crushing shaft 16 synchronously drives the drive wheel 25 and the pinion 17 to rotate at the same speed. The drive wheel 25 transmits power to the reduction wheel 10 through the first belt 11, causing the reduction wheel 10 to rotate at a low speed and stably to match the crushing rhythm. This, in turn, sequentially drives the first feeding roller 39, the second feeding roller 9, the third feeding roller 8, and the fourth feeding roller 7 to achieve multi-stage synchronous rotation in the same direction. Each feeding roller, with an anti-slip layer 35 on its surface, continuously clamps and pushes the waste copper material along an upwardly inclined and curved arc-shaped channel, increasing the friction between the material and the roller surface and preventing slippage, idling, or poor feeding. Meanwhile, the arc-shaped channel gradually guides the material into the crushing chamber in a regular manner, avoiding messy stacking and bridging. At the same time, the pinion 17 drives the reduction gear 13 to rotate at a low speed through meshing transmission. During the rotation of the reduction gear 13, the connecting rod 41 and the active pressure ball 42 move in a uniform circular motion. The active pressure ball 42 periodically extends into the arc-shaped groove 29 and slides, pushing the pressing plate 28 to swing back and forth around the pin shaft, thereby stably triggering the pressing switch 30 to generate an on / off signal. The pressing switch 30 transmits the signal to the controller 6 in real time. The controller 6 controls the electric telescopic rod 4 to extend and retract according to the signal. The electric telescopic rod 4 drives the pressing plate 21 to move up and down to press the material. The pressing plate 21 moves up and down to press the material in the limiting groove 20 and the limiting position. Under the guiding and limiting action of the slider 22, it maintains stable vertical movement without deviation, shaking, or jamming, continuously and smoothly pressing the material at the feed inlet into the crushing area, ensuring uninterrupted material entry between the blades, preventing empty blade operation and material accumulation. During the rotation of the reduction gear 13, the mounting ring 38 synchronously drives multiple balance bars 37 and sliding limit balls 36 to slide smoothly and stably along the annular groove 26 and inner annular groove 27 on the housing 1, forming radial and axial double limiting for the reduction gear 13, ensuring that it does not shift, deviate, or fall off during long-term operation, improving transmission stability and reliability. Under the action of gravity and pressing, the material entering the crushing chamber continuously enters between the moving blade 18 and the fixed blade 19. The high-speed rotating moving blade 18... In conjunction with the fixed blade 19, a continuous shearing process is formed to stably shred, cut, and tear waste copper materials. After crushing, the material falls onto a semi-circular screen 24 for grading and screening. Qualified materials that meet the particle size requirements pass smoothly through the screen 24 and are stably discharged through the discharge port 23 at the bottom of the shell 1. Unqualified materials with excessively large particle sizes are retained in the crushing chamber and continue to be sheared and crushed until they reach the qualified particle size. The arc-shaped pads 15 at both ends of the screen 24 tightly abut against the inner wall of the shell 1 to form a sealing structure, preventing material leakage from gaps and avoiding direct discharge of uncrushed materials, thus ensuring screening accuracy and crushing effect. The entire process of feeding, guiding, pressing, crushing, screening, and discharging is completed synchronously using a single power source.This technology effectively solves the problems of traditional equipment, such as complex multi-motor drive structures, high energy consumption, large space occupation, poor power matching, easy material bridging, disordered feeding, empty blade operation, poor crushing continuity, easy wear of blade sets, easy material leakage from the 24-inch screen, and uneven output particle size. It significantly improves the continuity, stability, and efficiency of waste copper dismantling and crushing operations, reduces equipment failure rate and labor maintenance costs, and can meet the needs of large-scale, continuous waste copper recycling and dismantling.
