1. Integrated Vibration‑box Driving Structure for Stable Operation & Less Wearing‑part Loss
QTF3‑20 adopts integrated vibration‑box structure instead of traditional direct‑driven vibration motor. It delivers exciting force of 50KN and vibration frequency of 4500 times per minute, transmitting uniform vibration energy to the whole mold box. The vibration unit runs inside sealed housing with oil‑bath gear lubrication, effectively avoiding frequent motor burnout caused by heavy‑load vibration and extending service life of vibrating components. Table‑type platform vibration transfers vibration from pallet bottom, making raw material fully agitated and degassed inside mold cavity for consistent compaction for both color pavers and hollow blocks. Main frame is welded with high‑strength 12×12 cm square steel, resisting deformation under long‑time high‑frequency vibration and preventing weld‑joint loosening.
2. Built‑in Independent Color‑facing Feeder for Double‑layer Color Paving Products
Equipped with integrated dedicated color‑facing feeder as standard configuration, the machine realizes separate feeding for colored surface layer and base material without extra retrofitting. It is specially developed for manufacturing double‑layer color paver bricks, interlocking blocks, grass‑planting blocks and other municipal‑landscape concrete products. The color feeder is hydraulically driven with precise timing interlock synchronized with main forming cycles. Feeding depth and travel speed are adjustable via control system, ensuring even thickness of colored surface and avoiding color‑material mixing with base concrete. After installing matched paver molds, operators can directly produce clean, well‑defined double‑layer paving bricks, well‑suited for small‑medium block plants focusing on municipal paving products.
3. PLC & HMI Intelligent Control with Complete Safety Interlock & Fault Diagnosis
PLC programmable controller cooperates with human‑machine touch‑screen interface. All technical parameters including pre‑vibration duration, main‑vibration time, pressing holding time and feeding cycles can be adjusted on screen. Process profiles for different brick types can be saved and recalled directly for fast product change‑over, cutting repeated debugging time. Complete electrical action interlock is implemented: pressing head and mold box cannot descend before feeding trolley fully retracts, preventing mold scraping damage from program logic level. Built‑in fault alarm displays error messages on screen under abnormal oil pressure or limit‑switch signal loss, simplifying troubleshooting. Both manual single‑step mode and fully‑automatic continuous mode are available. Operators can master production workflow after short‑term training.
4. Reliable Hydraulic System for Long‑time Continuous Small‑scale Mass Production
Rated hydraulic pressure reaches 16 MPa with well‑known Taiwan Calyca hydraulic components, delivering stable pressure for pressing head, mold box lifting, material trolley and color feeder. Optimized oil‑circuit layout reduces pipeline bending and oil‑leak risks. Under continuous mass‑production of colored pavers, pressure fluctuation is minimized to guarantee consistent compaction force for every mold and uniform block strength. Pressing head and mold box move with controllable gentle speed. Slow demolding protects paver and interlocking‑brick green bodies from corner chipping. Independent hydraulic station is placed away from host‑machine vibration and heavy dust, lowering foreign‑particle invasion into valve assemblies and prolonging hydraulic component service life. Daily maintenance and inspection are simple.
5. Versatile Mold Compatibility, Carburized Manganese‑steel Molds with High Forming Precision
Pallet dimension is 680×550 mm, supporting various mold sets. One machine can produce perforated bricks, hollow blocks, standard bricks, color pavers, interlocking blocks, slope‑protection blocks and curbstones. Molds are made of manganese steel material with carburizing heat‑treatment and wire‑cutting processing for high cavity precision and excellent wear resistance, ensuring regular product geometry in mass‑production. Wearing mold parts can be replaced separately instead of whole‑mold replacement to lower consumable cost. After mold change, clearances among pressing head, mold box and pallet can be quickly calibrated, enabling fast commissioning to fulfill diversified market orders.
6. Broad Raw‑material Compatibility for Cost‑saving Solid‑waste Recycling Production
This machine accepts diversified raw materials: sand, stone, stone powder and cement. It can also utilize industrial residues such as fly ash, furnace slag, gangue and expanded perlite for non‑fired block manufacturing. Reasonable control of aggregate particle size guarantees finished‑product strength. Customers can adopt local available waste resources to reduce cement dosage and raw‑material procurement expenses. By adjusting mixing formulas, users can produce qualified paving bricks as well as wall‑building blocks, complying with green building‑material and solid‑waste‑recycling policies.
7. Compact Footprint for Low‑threshold Project Implementation & Complete After‑sales Support
Overall dimension of QTF3‑20 is 5990×4260×2620 mm. Compact layout requires no extra‑large workshop space, lowering site‑investment threshold for small‑and‑medium investors. Machine is split into modular packages for convenient container sea transportation. After on‑site positioning, leveling, pipeline and cable connection, manual‑joint‑automatic test‑run can be carried out for trial production. Manufacturer provides mold‑installation guidance, reference mixing ratios and troubleshooting tips for common brick‑defects. One‑year full‑machine warranty is offered. Original spare parts including molds, vibration‑box assemblies and hydraulic sealing kits are continuously supplied to keep production line stable.
