1. Integrated Mechanical‑Electrical‑Optical‑Hydraulic Cooperation with Precise Non‑contact Proximity‑switch Monitoring
QT4‑20C semi‑automatic brick making machine integrates mechanical, electrical, optical‑sensor, hydraulic and high‑frequency vibration technologies. The workflow including pallet feeding, material distribution, vibration‑pressing, demolding and block discharging adopts non‑contact proximity switches for position signal collection. It eliminates traditional mechanical limit switches and reduces signal‑failure risks caused by mechanical collision and wear. Strict electrical interlock ensures subsequent actions cannot start until previous procedure finishes, preventing mold collision damage from mis‑operation. Stable timing‑logic and sensitive signal response adapt to heavy‑dust workshop environment, lowering mis‑judgement failure rate and guaranteeing reliable semi‑automatic cycle operation.
2. Composite Molding Technology with Hydraulic Pressure Priority & Table‑vibration Auxiliary for High‑quality Blocks
Adopting table‑vibration mode with vibration frequency 50‑70 Hz and vibration acceleration 10‑15 g. Hydraulic pressing serves as main driving force while high‑frequency vibration acts as auxiliary power. Pre‑vibration pushes raw material to fill every corner inside mold cavity and expel trapped air bubbles. Stable hydraulic pressing during forming stage realizes even compaction for green blocks. Compressive strength of finished blocks can reach above 15 MPa with good frost‑resistance, impermeability, sound‑insulation and heat‑insulation performance and high dimensional accuracy. Multi‑layer rubber shock‑absorbing assemblies weaken vibration transfer to frame and foundation, lower noise and slow frame fatigue to keep consistent product quality during long‑time production.
3. Stable 19 MPa Hydraulic Driving System with Gentle Movements for Multi‑product Forming
Rated hydraulic working pressure is 19 MPa. Core hydraulic components adopt imported or domestic famous brands, delivering steady power for pressing‑head movement, mold‑box lifting, feeding trolley and pallet feeder. Independent hydraulic power unit is placed away from host‑machine vibration source to reduce dust contamination into valve groups. Reliable oil‑joint sealing minimizes oil‑leakage risks. System pressure can be adjusted according to different products such as hollow blocks, standard bricks and paving bricks. Gentle lifting‑and‑demolding movement protects green blocks from corner chipping and edge breaking. Low‑pressure no‑load trial‑run is allowed during commissioning to protect oil cylinders and valves and extend hydraulic‑component service life.
4. Reasonable Pallet & Multi‑cavity Layout, Multi‑function Production with Convenient Mold Replacement & Commissioning
Pallet dimension reaches 1020×575×30 mm. One single pallet produces 4 pcs 390×190×190 mm hollow blocks, 28 pcs 240×115×53 mm standard bricks or 12 pcs 240×115×90 mm eight‑hole bricks. By changing molds, it manufactures hollow blocks, standard bricks, eight‑hole bricks, grass‑planting blocks, paving bricks and curbstones for building‑wall and municipal‑landscape projects. Clear mold positioning structure enables fast calibration of pressing‑head lower position, proximity‑switch location and feeding‑box height after mold swap. Simple brick‑pressing test completes commissioning for trial‑production. Wearing mold parts can be replaced separately instead of whole‑mold replacement to cut consumable cost.
5. Wide Raw‑material Compatibility for Cost‑saving Green Production with Industrial‑waste Utilization
QT4‑20C brick making machine supports sand, stone powder and cement as basic raw materials. Large proportion of industrial residues such as fly ash, furnace slag and coal gangue can be utilized for brick‑making. Multiple sets of reference mixing formulas are provided in operation manual. Customers can adjust formulas with local sand‑stone and waste resources to reduce cement dosage while meeting strength requirements. Maximum coarse aggregate size shall not exceed 15 mm. Making full use of local solid‑waste complies with green building‑material recycling policies and greatly cuts raw‑material procurement cost for block factories.
6. Compact Overall Structure, Standardized Installation‑commissioning Procedure & Clear Daily‑maintenance System
Overall dimension is 6950×2000×2600 mm with total machine weight 4200 kg. It is delivered in split modules: main forming host, pallet feeder, block conveyor and hydraulic station for convenient transportation and hoisting. Clear requirements for foundation flatness and horizontal level. After positioning, leveling, pipeline and cable connection, operators shall perform low‑pressure no‑load debugging, single‑unit test and full‑machine joint brick‑pressing trial in sequence. Operation manual specifies lubrication interval, bolt‑tightening cycle, hydraulic‑oil replacement cycle and wearing‑part replacement cycle. Troubleshooting guides cover common defects including conveyor belt deviation, uneven feeding, insufficient hydraulic pressure and poor vibration effect to shorten production‑line downtime.
7. Complete Safety Protection, Full‑set Process Guidance & Reliable Project‑landing Support
Complete safety operation regulations are specified: power supply must be cut‑off during maintenance; safety lifting tools are required for mold replacement; only qualified flat pallets are allowed for production. Besides machine hardware, manufacturer supplies complete mixing‑ratio reference and curing‑process guidance, including block stacking mode, water‑spray curing requirement and 28‑day delivery rule. After‑sales warranty service is offered. Original spare‑parts including molds, vibration‑box assemblies, hydraulic sealing kits and proximity switches are continuously supplied. Operators can take post after reading manual and hands‑on training, well‑suited for stable production of medium‑scale block plants.
