Why Uniform Rubber Blocks Matter
In a complete tire recycling plant, feeding long rubber strips directly into fine grinders leads to frequent equipment jams and premature roller wear. The rubber block cutter machine provides the necessary intermediate sizing step.
Operating downstream from the tire strip cutter , this unit shears irregular 3-5 cm wide strips into standardized, compact pieces. By producing consistent lengths, the equipment protects expensive downstream machinery, stabilizes the continuous feeding process, and optimizes the overall granulation capacity.
Precision Shear Technology & Anti-Jamming System
The mechanical core of this waste tire block cutter relies on a high-speed rotational shear mechanism utilizing two moving knives and one fixed knife. Operating at a uniform speed of 380 r/min, the cutting head generates immense torque. To ensure internal steel wires are severed cleanly rather than pulled apart, operators must maintain a strict 0.1 mm clearance between the moving and fixed blades during operation.
For operational safety and continuous workflow, the machine incorporates a compression gear that automatically pulls and feeds the material post-insertion. An integrated overload protection system safeguards the electrical components. If an oversized or overly dense rubber strip enters the chamber causing a jam, the motor shuts off automatically to prevent structural damage. The operator can then engage the manual reverse switch to clear the blockage quickly and safely.
Scalable Solutions: QKJ-358 vs. Upgraded Models
Processing requirements vary based on facility size and targeted output. Shuliy Machinery engineers have configured two distinct models of the tire block cutting machine to match different throughput demands. Whether outfitting a regional facility with the 5.5 KW common model or investing in 1500kg/h scrap tire recycling equipment, the core cutting consistency remains identical.
Below is the technical data comparison for varying production scales:
| Technical Parameter | QKJ-358 Common Model | Upgraded Heavy-Duty Model |
|---|---|---|
| Motor Power | 5.5 KW | 18.5 KW |
| Machine Capacity | 800 kg/h | 1500 kg/h |
| Blade Rotation Speed | 380 r/min | 380 r/min |
| Specification of Cutting Blocks | 3 × 5 × 6 cm | 5 × 5 cm |
| Dimensions (LWH) | 1.0 × 0.8 × 1.4 m | 1.3 × 1.1 × 1.5 m |
| Machine Weight | 800 kg | 1200 kg |
Minimizing Operating Costs with Alloy Blades
Consumable replacement often constitutes the highest ongoing cost in rubber processing. To address this, the cutting blades on the tyre block cutter are forged from specialized hard-wear resistant alloys. These blades withstand the abrasive nature of vulcanized rubber and embedded steel cords over extended production cycles.
Rather than discarding worn blades, maintenance personnel can detach and repeatedly grind the alloy edges to restore optimal cutting shear. This specific material design lowers the life-cycle maintenance cost of the equipment. Consistent blade sharpness also guarantees that the final rubber chunk cutter output maintains exact physical dimensions, yielding 3x5x6 cm or 5x5 cm blocks depending on the selected machine model.
Downstream Integration in Tire Recycling Facilities
Outputting uniform material is the primary prerequisite for automated material handling in subsequent processing stages. Standardized blocks feed seamlessly via conveyor belts into the Rubber Grinder or secondary shredders without bridging in the hopper. As a highly reliable rubber chunk cutter, the Shuliy QKJ series reduces manual handling interventions while maximizing the hour-by-hour throughput of your entire rubber recycling line .
