Description

Technical Field

[0001] This invention belongs to the technical field of waste metal recycling equipment, specifically relating to a waste metal recycling and processing equipment. Background Technology

[0002] In the field of waste armored cable recycling, traditional processing methods often use a circular cutter to peel off the cable sheath, simultaneously cutting the armor. The armor forms a C-shaped metal segment. During the separation of the sheath and conductor, as the distance between them increases, the sheath and conductor lose their restraint on the armor, causing it to fall under its own weight. The conductor, after passing completely through the circular cutter, falls to the ground, where it is manually collected for recycling. This recycling method lacks a conductor recovery device, resulting in a significant length of conductor remaining after sheath removal. This necessitates reserving considerable output and storage space on the circular cutter's output side, and requires long transport vehicles. Furthermore, the C-shaped cut armor can easily become stuck inside the sheath, leading to incomplete peeling and requiring manual peeling later, increasing labor costs and impacting overall recycling efficiency. Moreover, the separated armor, sheath, and conductor are scattered mixed on the ground, requiring manual sorting, further reducing the efficiency of metal recovery from waste cables. Summary of the Invention

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: Specific implementation examples Figure 1 , Figure 2 As shown, this invention relates to a waste metal recycling and processing device, including a pair of drive wheels 1. A guide plate 2 for waste metal is provided on the input side of the drive wheel 1. A cutting circular blade 101 is provided on the drive wheel 1. The waste metal includes a conductor, armor and a sheath sequentially wrapped around the conductor. A stripping and collecting unit and a crushing unit are provided on the output side of the drive wheel 1. The stripping and collecting unit is used to recover the armor, and the crushing unit is used to crush the conductor. The stripping and collecting units are respectively located on the left and right sides of the output side of the drive wheel 1. A first pair of conveying rollers 3 with a sheath is provided between the stripping and collecting unit and the drive wheel 1. A second pair of conveying rollers 4 with the conductor is provided between the crushing unit and the drive wheel 1. A guide roller 13 is provided between the second pair of conveying rollers 4 and the drive wheel 1.

[0016] The drive wheel 1 drives the cutting circular blade 101 to rotate, cutting open the waste cable along its axial direction. The sheath is driven by the first conveying roller 3 to be conveyed along a preset path and bent and reversed. During the reversal, the inner side of the sheath is folded outward, causing the armor stuck on the sheath to fall off, improving the success rate of separating the armor from the sheath. The fallen armor falls into the stripping and collection unit, eliminating the need for manual secondary stripping of the armor and picking up the scattered armor from the ground. After being conveyed by the first conveying roller 3, the sheath falls to the side of the drive wheel 1, while the conductor is driven by the second conveying roller 4 to enter the crushing unit. The crushing unit crushes the conductor to shorten its length, reducing the requirements for discharge space, storage space and transfer vehicle.

[0017] This embodiment utilizes the first conveying roller 3, the second conveying roller 4, and the stripping and collection unit to achieve the separation of sheath, armor, and conductor, preventing the three from mixing and scattering at the source. This eliminates the need for manual sorting, helps improve recycling efficiency, and reduces labor costs.

[0018] The crushing unit includes a crushing box 5 and a crushing assembly disposed within the crushing box 5. The crushing assembly includes a first drive roller 6 and a second drive roller 7. The crushing box 5 is located below the second conveying roller pair 4. A feed inlet 501 is provided above the crushing box 5, and a discharge chute 502 is provided below the crushing box 5. The feed inlet 501 is connected to the output end of the second conveying roller pair 4. The second conveying roller pair 4 conveys the conductor separated from the sheath into the crushing box 5 through the feed inlet 501. The crushed conductor is discharged out of the crushing box 5 through the discharge chute 502. Figure 2 , Figure 3 As shown, a first cutter disc 8 and a second cutter disc 9 are respectively interposed on the first drive roller 6 and the second drive roller 7. The first cutter disc 8 on the first drive roller 6 and the second cutter disc 9 on the second drive roller 7 are arranged opposite to each other, that is, the first cutter disc 8 on the first drive roller 6 is aligned with the side wall of the second cutter disc 9 on the second drive roller 7, and the second cutter disc 9 on the first drive roller 6 is aligned with the side wall of the first cutter disc 8 on the second drive roller 7. A set of blades 10 is provided on the first cutter disc 8 and the second cutter disc 9. The blades 10 of the first cutter disc 8 and the coaxial second cutter disc 9 are interposed in the circumferential direction. The first drive roller 6 and the second drive roller 7 rotate in opposite directions, causing the first cutter disc 8 and the second cutter disc 9 to mesh with each other, cutting long conductors and shortening the length of the conductor.

[0019] Tooth grooves are formed between adjacent blades 10 on the same cutter disc. The blades 10 of the first cutter disc 8 and the blades 10 of the opposite second cutter disc 9 are staggered and meshed. During the rotation of the first drive roller 6 and the second drive roller 7, the blades 10 of the opposite first cutter disc 8 and the second cutter disc 9 mesh with the tooth grooves to tear and cut the conductor.

[0020] Even if plastic deformation of the conductor occurs during the crushing process, the blades 10 in the first or second cutter disc 8, which are arranged opposite each other, come into contact with the conductor and pull it downward. The blades 10 of the other cutter disc then act on the conductor. The two blades 10 exert forces on the conductor from top to bottom, thereby achieving the breakage of the conductor.

[0021] During shearing, the conductor of the metal undergoes plastic deformation and can easily become stuck in the grooves of adjacent cutting edges 10, such as... Figure 3 As shown, the first cutter head 8 and the second cutter head 9 are respectively provided with a guide groove 11 and a material ejector block 12. The material ejector block 12 is guided and slidably engaged with the guide groove 11. The material ejector block 12 is located on the tooth groove of the first cutter head 8 and the tooth groove of the second cutter head 9 respectively. The material ejector block 12 has the freedom to be lifted on the first cutter head 8 and the second cutter head 9 with the help of the driving device. In the initial state, the material ejector block 12 is located in the guide groove 11. After passing the engagement position, the driving device drives the material ejector block 12 to be lifted. The material ejector block 12 pushes the conductor stuck on the tooth groove of the first cutter head 8 and the second cutter head 9, realizing the forced separation of the conductor from the first cutter head 8 or the second cutter head 9, ensuring that the first cutter head 8 and the second cutter head 9 are always in an effective shearing state.

[0022] like Figure 3 As shown, the first drive roller 6 and the second drive roller 7 are rollers, each with a gear at its end that is connected to the drive unit via the gear. The drive unit is a motor, and the drive device is located inside the roller. The lower end of the unloading block 12 has a sliding rod 1201 that extends into the cylinder cavity of the roller. The drive device includes a fixed shaft 14 with a protrusion 1401, which is fitted onto the roller. Both ends of the fixed shaft 14 extend outward from the roller and are fixedly mounted to the mounting frame of the crushing box 5. The first drive roller 6 and the second drive roller are roller-shaped. 7 is installed on the crushing box 5. The first drive roller 6 and the second drive roller 7 have the freedom to rotate around their own axis on the crushing box 5 with the help of a motor. The protrusion 1401 is suspended along the radial direction of the fixed shaft 14 toward the inner wall of the first drive roller 6 or the second drive roller 7. The slide rod 1201 passes through the protrusion 1401 in sequence with the protrusion 1401 by means of the rotation of the first drive roller 6 or the second drive roller 7 to form a lifting drive cooperation with the protrusion 1401. A spring 15 is fitted on the slide rod 1201. The spring 15 is located between the bottom of the guide groove 11 and the unloading block 12.

[0023] Specifically, when the conductor being cut gets stuck on the first cutter disc 8 or the second cutter disc 9, as the roller rotates, the slide bar 1201 passes the protrusion 1401. The protrusion 1401 exerts a pushing force on the slide bar 1201. Under the pushing force of the protrusion 1401, the ejector block 12 is lifted to push the stuck conductor out between the blades 10, automatically completing the ejection of the stuck conductor. Then, under the action of the spring 15, the ejector block 12 is pulled back to the initial position, avoiding incomplete cutting or equipment shutdown caused by conductor jamming, ensuring the continuous and stable operation of the crushing unit, and helping to improve the overall recycling efficiency.

[0024] In this embodiment, the crushing unit relies on the rotation of the rollers to force the unloading block 12 to be lifted, eliminating the need for an additional unloading drive source. This simplifies the structure and reduces energy consumption, which helps reduce the cost of recycling waste cables.

[0025] like Figure 1 , Figure 2 As shown, the stripping and collection unit includes a collection box 16 and a feeding roller 17. The collection box 16 is located below the first conveying roller pair 3. A guide roller 13 is arranged between the first conveying roller pair 3 and the conductor. The guide roller 13 abuts against the outer side of the sheath. The feeding roller 17 is arranged on the inner side of the sheath. Both the guide roller 13 and the feeding roller 17 are located above the collection box 16. The axial direction of the guide roller 13 is set at an angle to the axial direction of the feeding roller 17. The guide roller 13 and the feeding roller 17 clamp the sheath to flatten the arc-shaped sheath. The armor originally wrapped in the sheath loses the constraint of the sheath. The feeding roller 17 rotates to form a downward driving force on the armor on the sheath, ensuring that the armor is successfully separated from the sheath. The armor falls into the collection box 16, realizing the directional collection of the armor.

[0026] Preferably, the waste metal recycling and processing equipment includes multiple pairs of drive wheels 1, each pair of drive wheels 1 having a stripping and collection unit on its output side, and each pair of drive wheels 1 being matched with a crushing unit. This enables the simultaneous stripping of multiple cables and the crushing of multiple conductors, improving the utilization rate of the crushing unit, avoiding equipment redundancy, and increasing recycling efficiency.
