What is The Cable Granulator Machine Design Concept?

Wiki Article

Semi-automatic wire stripping machines, commonly used in scrap metal recycling and wire processing, offer advantages such as low operational barriers and moderate costs.

However, constrained by their "semi-automatic" mechanical structure and transmission principles, they exhibit the following core drawbacks in actual production-particularly insufficient adaptability for high-intensity, multi-specification processing scenarios like scrap metal recycling:

1. Limited Production Efficiency, Inadequate for Batch Recycling Demands

Reliance on manual intervention results in poor continuity:

Semi-automatic models require human operators to perform critical steps like wire feeding, positioning, and sorting, preventing full automation of the "loading-stripping-unloading" process. For bundled or tangled wires common in scrap metal recycling, manual disassembly and separation into individual strands is required before feeding. Each wire (or small batch) processed necessitates waiting for the machine to reset, resulting in significantly lower throughput per unit time compared to fully automated equipment (typically only hundreds per hour versus thousands for fully automated models).

Drive Mechanism Speed Bottleneck:

Relying on mechanical transmission like gears and belts, stripping speed is constrained by the physical limits of transmission components. At high speeds, wire slippage and positioning deviations occur, necessitating reduced speeds to maintain accuracy-further limiting efficiency. This makes it difficult to meet the core requirement of "mass processing" in scrap metal recycling for large-scale production.

II. Limited Applicable Wire Range and Poor Compatibility with Scrap Cables

Restricted Specification Adaptability:

Manual adjustment of parameters like blade spacing and stripping length is required. Machines can only reliably process wires of a single cross-section (e.g., 0.5-6mm²) and regular shape (circular). However, scrap wires in recycling often feature mixed specifications (ranging from thin household wires to thick cables), irregular shapes (flat wires, multi-core twisted strands), aging/damage (cracked outer sheaths, fused metal cores), or contaminants (oil, sand). This leads to common issues:

- Thin wires break due to insufficient tension; thick wires remain partially coated due to inadequate blade pressure.

Multi-core twisted wires become tangled after outer sheath removal, requiring secondary manual separation;

Contaminants cause transmission mechanism jamming and accelerated blade wear, further narrowing the adaptability range.

Unable to process specialized wires:

For scrap cables with shielding layers or armor, or wires with severely aged outer sheaths adhering to the metal core, semi-automatic wire strippers lack specialized handling mechanisms. Additional manual removal of outer layers is required, increasing process complexity.

III. Unstable stripping precision and high metal loss rate

Significant manual operation errors:

Positioning deviations during feeding and inherent cable bending/deformation cause inconsistent blade cutting depth. Minor issues leave outer sheath residue, while severe cases scratch the metal core, resulting in metal loss (especially critical in scrap metal recycling where core integrity directly impacts recovery value).

Precision degradation due to transmission wear:

After prolonged use, transmission components like gears and guide rails become prone to loosening and wear, causing blade trajectory deviation and further precision loss. In scrap metal recycling environments, high equipment usage frequency and complex operating conditions (e.g., wire containing impurities) accelerate transmission component deterioration, shortening stable operational cycles.

IV. High Labor Costs and Intensive Workload

Requires Dedicated Full-Time Operation:

Unlike fully automated equipment's "unattended operation," semi-automatic models necessitate personnel for feeding, sorting, parameter adjustment, and troubleshooting (e.g., material jams). Long-term labor costs accumulate significantly, and such models struggle to meet continuous production demands during nights, holidays, and peak periods.

Repetitive labor induces fatigue:

In scrap metal recycling, the high volume and diverse types of wire processing involve strenuous manual repetition of feeding and sorting tasks. Fatigue can lead to operational errors, further compromising efficiency and precision.

Thus, the fully automatic cable granulator recycling machine was born. It overcomes the shortcomings of semi-automatic machines with manual transmission. Simply feed in the cables continuously, and the machine will automatically separate plastic and copper granules.

It enhances recycling efficiency, reduces waste, and controls costs. We further recommend selecting models featuring automatic feeding, multi-specification adaptability, stable precision, and digital management capabilities.
